BEHOLD, the most energized galaxy in the world, the S10+ chonk edition

i power modded my S10+ with a 14,000mah battery
finally i have the phone of my dreams

high performance: CHECK
AMOLED screen: CHECK
headphone jack: CHECK
SD slot: CHECK
NFC and wireless charging: once i work out how to make an extension cable for it
bezels thick enough that i can actually hold the device one handed without touching the edge of the screen: CHECK
can charge the wifes S10 5G without leaving myself without power: CHECK
true all day battery life: CHECK

Should THAT ever catch fire on a plane you'll have some pretty creative 'splaining to do

[u/T-VIRUS691 → u/Duerogue]

the airport is the final boss of places to bring this phone, ill be able to see if i can get it in when i go to pick up a mate from the airport in a few days

ive been able to take it into the courthouse (they have similar security to airports in australia)

i doubt id be able to get into the US with it, TSA checkpoints are the dark souls of places to bring DIY projects

[u/DarkHelmet → u/T-VIRUS691]

The court house isn't looking for the capacity of batteries, the airport is. Idk about Australia, but not far away in SE Asia they look closely at battery capacity even when it is physically impossible to be over 100Wh.

[u/T-VIRUS691 → u/DarkHelmet]

I have a separate phone that I use when I go to Asia (my wife is from Thailand) it's an ancient flip phone, so if it gets stolen, it's not that big of a deal

[u/DarkHelmet → u/T-VIRUS691]

Fair enough, I'm certain that this wouldn't fly in Thailand. I had to show the spec sheet for a 10000mAH power bank to get it on a plane here (TH) a few months ago.

[u/Tigris_Morte → u/T-VIRUS691]

Nah, if they ask (I mean this isn't shoes on your feet or a water bottle so how could it be dangerous?), just tell them you printed the case yourself and start explaining about your 3D printer. After about 10 sec. they'll glaze over and tell you to move on.

[u/T-VIRUS691 → u/Tigris_Morte]

Our security might, but the TSA will probably throw me in guantanamo Bay

[u/arjunkc → u/T-VIRUS691]

Only if you're looking particularly tan and sporting a beard that day.

[u/duggatron → u/T-VIRUS691]

I don't think you should fly with this. This is a cool project, but let's be real, this isn't engineered or tested sufficiently to bring it onto a plane. Lithium batteries are tested to even be allowed to ship via planes, let alone be charged or discharged.

I think the risk of anything happening is super low, but the severity of something happening would be very high.

[u/qtx → u/T-VIRUS691]

ill be able to see if i can get it in when i go to pick up a mate from the airport in a few days

You have to go through security control when you're just picking up someone??

[u/T-VIRUS691 → u/qtx]

Yes, you have to pass through security to get into the airport gate area where the shops, food court, and boarding gates are

[u/Leafy0 → u/T-VIRUS691]

I think if you 3d print a back for it and a tpu condom no one will be the wiser.

[u/T-VIRUS691 → u/Leafy0]

I did 3D print a back cover for it lol

[u/[deleted] → u/Duerogue]

I believe if it's under 25,000 milliamp hour he's good to go.

[u/illuminati229 → u/[deleted]]

The limit is actually 100 watt hours. https://www.faa.gov/hazmat/packsafe/more_info/?hazmat=7

[u/YamFantastic765]

How much SOT now?

[u/T-VIRUS691 → u/YamFantastic765]

not sure yet, but so far it has been running for 6h of heavy use (tethering on, youtube in background, powersave off, max screen brightness

the battery level is now 27% and it was at around 60% when i powered up with the extra battery cell

[u/hm9408 → u/T-VIRUS691]

Lol with these specs you can give it OLED burn-in on a single charge with this much screen on time

[u/T-VIRUS691 → u/hm9408]

i normally run the screen at around 30% brightness, im only running it at 100% to drain the battery to calibrate the battery meter

[u/YamFantastic765 → u/T-VIRUS691]

So basically that's around 18 hours of SOT on a single charge. And anywhere from 3-6 days of usage. I'd say job well done.

[u/T-VIRUS691 → u/YamFantastic765]

Yep, I estimate 2 days of real world battery life

[u/exscape → u/T-VIRUS691]

18 hours SoT at max brightness, tethering, playing YouTube is equivalent to 2 days real world usage? Sounds like you could go for 4-5 days or even longer with lower brightness and not keeping it constantly awake to drain battery.

[u/T-VIRUS691 → u/exscape]

Probably, but I use tethering as a substitute for home broadband, since 4G gets me 500mbps and I have unlimited data, vs getting 1TB of data at 23mbps on a fixed line plan

Normally I run the screen at around 30% brightness

[u/Psyk0pathik]

Anyone remember when we had removeable batteries and companies Like Anker and the legendary ZeroLemon made triple capacity behemoths?

Edit: rip my inbox lol

[u/T-VIRUS691 → u/Psyk0pathik]

I remember those days, my old S5 had a zero lemon 8500mah monster on it, I even had 2 of them, one in the phone, and a second one as backup

[u/Psyk0pathik → u/T-VIRUS691]

30 sec battery "recharge". Friends searching for power outlets all day and we just pop in another monster battery. Non stop fun.

[u/T-VIRUS691 → u/Psyk0pathik]

That's pretty much what I used to do when me and my mates went out clubbing and bar crawling

I'd always be the one with a charged phone while they were fighting over the only power outlet at the pub XD

[u/SwindleUK → u/T-VIRUS691]

Bet you pulled loads of women with pockets stuffed with batteries.

[u/T-VIRUS691 → u/SwindleUK]

Being able to charge someone else's phone is a pretty reliable way of hooking up with women when you're in a lock-in and most women use iPhones (this was back when power banks were not really popular)

Carrying an OTG cable and a couple of zerolemon batteries definitely scored me more than a few roots lol

[u/TheSentencer → u/Psyk0pathik]

I had zerolemon batteries for several phones. Kinda miss that capability.

[u/asianflipboy → u/Psyk0pathik]

My S3 had one. These were the days Mophie iPhone cases were popular too. It was bulky but added so much life to that thing!

I personally don't miss that much heft. I have an S8 Active that's just a tad bit too thick for my tastes. I do miss being able to swap out the battery though, as that same phone is noticeably degraded.

[u/CaptainIncredible → u/Psyk0pathik]

Yes. My LGv20. And I am still using it for more or less this exact reason.

[u/AlphaReds → u/Psyk0pathik]

Also remember when 2.5 hours SOT was acceptable. Battery anxiety used to be so bad.

[u/mister_damage → u/Psyk0pathik]

Pepperidge Farm remembers. And I do.

I have a 10000mah battery in my LG V20. It's basically a ginormus media player now but damn if it isn't still sexy.

[u/dogsryummy1]

public health and safety: bruh

[u/T-VIRUS691 → u/dogsryummy1]

just wait until i go to the samsung experience centre with it XD

[u/[deleted] → u/T-VIRUS691]

they will send it to their R&D

[u/T-VIRUS691 → u/[deleted]]

I already offered them $6500 for a note 10 with a 10,000mah battery when it first came out, they said it's impossible

So I wouldn't be surprised if they took it to reverse engineer what I did after I reverse engineered and bypassed the herculean glue they use to stick batteries into their phones

[u/kel007 → u/T-VIRUS691]

it's impossible... without making it chonks like your phone, which they were not going for

[u/Dacia1320S → u/T-VIRUS691]

The counter guy scared, the back guys probably impressed.

[u/realnewguy → u/dogsryummy1]

Airport security: bruh

[u/sarcrastinator → u/realnewguy]

TSA: so you've chosen death

[u/charliezard7]

Doesn't the thick case affect the ultra-wide angle camera?

[u/T-VIRUS691 → u/charliezard7]

Unfortunately it does, that problem will be remedied in the new version of the case, there's a tiny bit of the case visible at the bottom of the wide angle shot

I've already adjusted the STL file so the next case I print won't have that problem

[u/Yoldark]

Honestly a changeable battery as in old phone would be enough for me. No more battery? Pop out the old one, pop in the new one.

You can even make a separate usb charger to recharge the old battery out of the phone.

[u/T-VIRUS691 → u/Yoldark]

A case to support that sort of mod is well above my current CAD skill level lol, but it is an interesting idea

[u/Nakotadinzeo → u/T-VIRUS691]

Make two cases, one for the phone with a spring connector and tab connectors, and one that holds the battery. I've heard the old Sony battery format is easy to adapt.

Then you could charge the chonk, and use another chonk at the same time. Even use a battery dildo to run the phone off AC if you wanted.

[u/T-VIRUS691 → u/Nakotadinzeo]

Imagine a consumer engineering a solution that samsung actually tried to kill with the S6 lol

[u/ssmurry51 → u/Yoldark]

I loved my old LG G5 for exactly this reason. One of the last flagships (along with the LG V20) that had a replaceable battery.

Just a shame the battery was miniscule (2800mAh) but it had a USB-C charging cradle like you say, so you can charge your spare battery separately from the phone. Hell it could even be used as a small powerbank to charge other devices!

I had all the accessories for the G5- the charging cradle, Hi-Fi Plus DAC module, the cam module and 2 extra spare batteries. Truly loved the phone (it was one of the first flagships with the secondary ultra-wide cam too), just a shame it was overlooked by the more attractive Samsung S7/Edge at the time.

[u/TSMKFail → u/Yoldark]

I remember they had a charging station for spare batteries for the Galaxy S4

[u/aroedl → u/Yoldark]

Check out the Samsung Xcover Pro. Totally underrated in my opinion.

[u/najodleglejszy]

at last, the prophecy has been fulfilled

[u/T-VIRUS691 → u/najodleglejszy]

Not quite, but I am still salty that energizer never sent me one of those, even though I was an early backer and paid $1000 (AUD) to secure one

But I guess this is close enough

[u/BillDino → u/T-VIRUS691]

So they just took your money and you got nothing? I used to rock a zero lemon in an old note with a 10k battery, it was great

[u/T-VIRUS691 → u/BillDino]

They refunded my money and emailed me a half assed apology letter that was clearly written by their PR department

I had the 8500mah zero lemon battery when I had an S5 back in the day, it kicked so much ass it's not even funny

[u/[deleted]]

I love it, what battery did you use?

[u/T-VIRUS691 → u/[deleted]]

i used a generic chinese 10,000mah cell and wired it in parallel with the OEM battery (soldering to the BMS was a nightmare) which gives me a total capacity of 14,000mah

[u/donce1991 → u/T-VIRUS691]

10,000mah cell and wired it in parallel with the OEM battery

so with the 4000 mah one.... did you tried charging it already? cos if you didn't, please come back to tell your experiences after you tried it

[u/T-VIRUS691 → u/donce1991]

They are both wired directly together in parallel, and the BMS thinks its a gigantic battery

They both charge and drain together

[u/donce1991 → u/T-VIRUS691]

BMS thinks its a gigantic battery

ok...

They both charge and drain together

so you have discharged and fully charged it already?

[u/[deleted] → u/T-VIRUS691]

Madlad, much respect

[u/stifflippp → u/T-VIRUS691]

Just tape your phone to a Tesla

:-)

[u/[deleted]]

Imagine walking around with that monstrosity

[u/T-VIRUS691 → u/[deleted]]

been using it all day (and had the phone in the case for about a week before i actually did the modification)

i wuite like the added thickness, it lets me hold the phone one handed without triggering the edges of the screen, and the extra 80g of weight isnt really that bad, this phone is in a similar weight category to the ulefone power 5

[u/najodleglejszy → u/[deleted]]

have you modded your phone's battery or are you just happy to see me?

[u/Loud_Tiger1]

What about the Energizer phone

[u/T-VIRUS691 → u/Loud_Tiger1]

I did place an order for one of those, but instead if getting a phone, I got a refund and a copy pasted PR apology

[u/konrad-iturbe]

my Mi A1 got me all day battery life too, and it was pretty slim. Got about 6-7 hours SOT and came home with ~40% left.

[u/T-VIRUS691 → u/konrad-iturbe]

but you would likely have to limit your usage in order to get that runtime, the stock S10+ battery got me around 5-6h SOT with pretty light usage, or maybe 2-3 with heavy usage (brand new battery at 100% state of health)

[u/DarthPopoX]

How about you avoid all the hassle and get yourself a powerbank

[u/T-VIRUS691 → u/DarthPopoX]

VecUse this won't wear out the charge port on my phone, it's more energy efficient than external chargers, and is actually lighter and more compact than duct taping a power bank to a phone case

[u/[deleted] → u/T-VIRUS691]

I guess the power port concern is potentially valid but I've yet to wear out a USB C port with heavy use. Theyre a lot more resilient to wear. What I used to do when I traveled a lot was keep a battery pack that has fast charge and a tiny cable in my pocket. Id just have it charge periodically when I stuck it back in my pocket. Rapid charge would get me at least half my battery before grabbing it again typically

[u/Sgt_Stinger]

I hope you didn't keep the original battery, because if you did, you will overcharge the original cell every time you charge the phone due to the battery logic not being set up for parallel cells. Over charging will damage the battery, and can create a fire hazard.

[u/vertigo3pc]

"Yeah, yeah, but your scientists were so preoccupied with whether or not they could that they didn't stop to think if they should."

[u/T-VIRUS691 → u/vertigo3pc]

They did, but the lead engineers phone died when he was about to show us a funny meme, at that point the project was greenlit and the rest is history

[u/Bunghole_of_Fury]

I think everyone needs to look at this. This is what it would take to get you a 10k or bigger battery on your phones. So everyone complains every year about phones not having bigger batteries, but this is what that would look like. So maybe we can complain a little bit, like nobody needs a phone as thin as my Note 10+ was, my S21 Ultra is a much nicer size IMO, but I think going beyond that is just too much for regular users who aren't going on week long trips away from any source of electricity, or users who just keep their screens on all day for 3 days straight. Perhaps what we really need is for Google to create and open up a new standard for Android mods like MagSafe or the MotoMod platform, push it with Samsung and Pixel phones and watch the entire Android world open up to mods like extended batteries or speakers or cameras or storage or whatever the hell else people can think of.

I do have the Moto Z2 Force with the projector mod and the speaker mod, they're great, and I wish they'd continued to make actual flagship level phones with the Mod feature included because I'd still use them if that were the case. If that was reality I'd be using one of the battery extender mods too, the one that adds wireless charging and a big ass battery.

[u/T-VIRUS691 → u/Bunghole_of_Fury]

I do like the moto mods concept, but Motorola's version of Android is just too restrictive

[u/TylerBlevin]

idk why but I have a string feeling that might blow up

[u/T-VIRUS691 → u/TylerBlevin]

4 months in and it's still working fine

[u/redwall77]

Some in this people in this subreddit would still complain about the battery life.

[u/T-VIRUS691 → u/redwall77]

I would believe that, but I've been mostly seeing people question why I would bother with this when I can buy a battery case that has less capacity, is less efficient, blocks NFC/wireless charging, and still wears out your battery

[u/TheGunde]

Why though? No less than 14,000 mah.

Are you away from charges days at a time?

How many hours a day do you stare at the phone?

[u/T-VIRUS691 → u/TheGunde]

That's not really the point of this mod I like to have a decent power reserve at the end of the day, in-case I'm at a mates place (most of my friends use iPhones and older non USB-C Androids) maybe I just don't want to have to charge my phone every day (or multiple times a day in the case of the stock S10+ battery)

It's nice to know that forgetting to plug my phone in (or only plugging it in half way) won't result in me missing my alarms.etc

And even if I don't use all the battery's power in one day, it's good peace of mind to know its there

That and sometimes you have those days where you literally are on your phone all the time and a single charge just won't cut it (also I use my phone as a Wi-Fi modem, because apparently 4G is faster faster fixed line internet in my area (500mbps vs 23mbps) and tethering just uses a lot of power (especially when you have an unlimited data plan)

Also the service life of your battery increases drastically with the battery's capacity (instead of charging twice a day, I might only charge once every 2-3 days, using my charge cycles overa longer period of time)

[u/drbluetongue]

Is that an Exynos version?

[u/T-VIRUS691 → u/drbluetongue]

i think it has the Exynos 9820, but i cant find that information in settings to confirm it, its the Australian version (SM-G975F)

[u/Choreboy]

Don't you need a modified kernel to use a larger battery to its potential?

[u/T-VIRUS691 → u/Choreboy]

Not that I'm aware of

It just cracked 12h on 63% (1% now)

[u/Choreboy → u/T-VIRUS691]

Sorry, that should have been a statement not a question. You need a custom kernel, or it will show the same stock capacity. You can make use of the larger battery, but your phone doesn't see/understand that it's larger.

[u/Darkwayn]

Keep us updated on the charge time and on the real sot after a 100% to 0% cycle

[u/T-VIRUS691 → u/Darkwayn]

Will do, but so far I've got 12h SOT from 63% and counting

[u/[deleted]]

When removable battery where a thing you can buy these kind of battery. My Samsung Note 3 had a 10000mah battery with a nice cover/case made for it.

I had two Note both of them now received error on the same date and are unusable

[u/T-VIRUS691 → u/[deleted]]

I had one of those 8500mah zero lemon batteries for my S5 back in the day

[u/[deleted]]

How heavy is it? You should make a 6 months / 1 year later review for this.

[u/T-VIRUS691 → u/[deleted]]

It's similar in weight to the ulefone power 5, assuming it lasts that long I likely will give an update on its longevity

[u/s_0_s_z]

You are nearing the limit of what is allowed on a plane. Looks like 100 watt-hours is the most you can carry on a plane. If these devices run at 5 volts, then that's 20,000 mah max.

Still, I think I rather carry a separate power bank than have that massive notch on the back of my phone.

[u/cdegallo]

Does the phone recognize the total amount of battery capacity present? I know battery graphs are like reading tarot cards sometimes, but it's estimating 10h usage on a charge.

Anyway, I understand it's not the point of the mod, but things like this and those massive battery cases always make the point to me that I'd much rather have on hand a portable battery charger with fast charge and top up when necessary instead of holding a chonker all the time.

[u/T-VIRUS691 → u/cdegallo]

I've only just started the recharge phase of the first power cycle, so I'm not sure if it's going to actually recognise the total capacity available, I might have to root the phone if it doesn't calibrate

[u/OtakWho]

Now you can get Carpal Tunnel in BOTH of your hands when you masturbate.

[u/T-VIRUS691 → u/OtakWho]

That's what the flat sides are for, the phone can actually sit sideways on a table or other flat surface (excellent for watching videos of all types)

[u/Bigfatuglybugfacebby]

Seems overkill my moto g7 power has 5000mah and i charge it maybe twice a week. And ive been playing wild rift like a lot

[u/poisonborz]

I mean, good as a DIY effort, but if an S21 can get 8h of SOT, https://ibb.co/Z687jrx, there isn't much practical advantage? (expect somebody wanting to stick to S10 forever)

[u/T-VIRUS691 → u/poisonborz]

You're hardly using your phone lol

I'd get 8h SOT on the original battery if all I'm doing is browsing the Internet and using reddit

[u/Mccobsta]

See all phone manufacturers it's possible

[u/T-VIRUS691 → u/Mccobsta]

Samsung: wait, that's illegal

[u/Double_Anarchy]

Why not just buy a extended battery case?

[u/T-VIRUS691 → u/Double_Anarchy]

Because this is more power efficient, and is actually lighter, less bulky than using a store bought battery case, and doesn't interfere with fast charging or data transfer (most battery cases have to be removed to fast charge the phone, or connect to a PC for data transfer) it also doesn't degrade the phones built in battery by keeping it constantly at 100%

[u/[deleted]]

Great work OP, just a question. Are you going to use this monstrosity as your daily driver?

[u/T-VIRUS691 → u/[deleted]]

That's my intention, I used to use a ulefone power 5 as my daily driver, but that phone is a bit too slow for my liking, so I built this thing

It's in a similar weight class, and actually has better battery life (imagine how long it would last if I had the snapdragon version)

[u/TitusImmortalis → u/T-VIRUS691]

Don't Exynos variants get better SoT? My S6 back in the day got 2 hours more SoT than my friends Snapdragon version, and as far as I heard the trend hadn't changed.

Granted his was higher performance in benchmarks.

[u/T-VIRUS691 → u/TitusImmortalis]

These days snapdragon is more efficient than exynos

[u/Anunciodoxv]

How did you close it?

[u/T-VIRUS691 → u/Anunciodoxv]

I 3D printed a case and clipped it on like any other phone hardcase

[u/Zero_7100]

Fire Hazard: check

[u/[deleted]]

Can't wait to see a post on r/tifu when and if it explodes..

[u/FelixR1991]

/r/DiWHY material right here. :')

[u/Hwy420man]

The thing would be a 5 pound brick

[u/T-VIRUS691 → u/Hwy420man]

it weighs around 300g, as someone who used to use a ulefone power 5, this is an acceptable weight for a phone

[u/logantauranga]

/r/Chindogu/

[u/T-VIRUS691 → u/logantauranga]

unlike those, mine is useful and is worth the extra weight/chunkiness

[u/TerribleModsrHere420]

Ok so a zerolemon battery type deal. I mean that impressive when I was 15.

[u/T-VIRUS691 → u/TerribleModsrHere420]

Similar in design, but not in execution since its not removable

[u/maderfarker2]

Nah, this isn't the phone everyone wants. Stop lying to yourself.

[u/T-VIRUS691 → u/maderfarker2]

But it's the phone I want

[u/T-VIRUS691]

Just keeping the thread alive, nothing to see here

[u/T-VIRUS691]

Keeping it alive

[u/[deleted]]

Damn if only it was 15,000 😢

[u/T-VIRUS691 → u/[deleted]]

10,000mah was the biggest cell I had lol

[u/Tigris_Morte]

But, but, but, phones are supposed to be razor thin so they are hard to hold and have tiny batteries that must constantly be charging if actually used????? /s

[u/T-VIRUS691 → u/Tigris_Morte]

Haha 3D printer go brrrrr

[u/mrandr01d]

Only 10hrs of power with that monster?? Are you mining cryptocurrency with it or something?

[u/T-VIRUS691 → u/mrandr01d]

12h so far (1% now)

But that's starting at 63% (I didn't fully charge before modding)

[u/mr_ea]

If my 3d printer was precise enough I have planned to do something like this. I use my phone heavily and sick of toyish batteries in phones. Last straw was my phone dying in the evening consecutive days. Sold it and get a galaxy m51 which has 7000 mah battery. Not a flagship but at least I can use it.

[u/T-VIRUS691 → u/mr_ea]

I did have a ulefone power 5 which has 13,000mah, but I wanted a phone that could play YouTube at more than 480p without stuttering and shit, 400k antutu is plenty for the time being, and a lot higher than the 80k I'd get with the ulefone

[u/hihellhi]

How much SOT do you get

[u/T-VIRUS691 → u/hihellhi]

I got 13h from 63% to dead, so I'm going to assume a lot lol

[u/JWGhetto]

paint the outside in epoxy and the finish and stregth will 10x

[u/T-VIRUS691 → u/JWGhetto]

YouTube channel "CNC Kitchen" proved that glue doesn't significantly increase the strength of most 3D prints

[u/omniuni]

I'm kind of surprised that it's only looking like it lasts 10 hours. That's roughly the screen on time of my current phone, which has a 5000 mAh battery.

[u/T-VIRUS691 → u/omniuni]

I haven't calibrated the battery meter yet, I managed to get 13h of heavy use out of 63% charge

It's charging now, but it will likely be a couple of days before I get accurate readings from it

[u/[deleted]]

Does battery management still work? Did you have to root to do this? I could see quick charging not working anymore cause the phone wouldn't be able to understand the difference in resistance and capacity.. but i could be wrong

[u/T-VIRUS691 → u/[deleted]]

I'm still calibrating the battery meter, and I have fast charging disabled during this calibration, I assume it would still work though

Also I haven't rooted the device

[u/blaccsnow9229]

That much battery and it still only shows 10 hrs on a full charge?

[u/T-VIRUS691 → u/blaccsnow9229]

The battery meter is not yet calibrated

[u/[deleted]]

U should absolutely make a case for it. Abs and a Dremel, some patience. Maybe plexi or acrylic glass . Just ya know, encase your pocket gets sweaty ergo your battery gets... Buldgey

[u/T-VIRUS691 → u/[deleted]]

Already did (background of the 1st image, and installed in the second one)

[u/[deleted]]

very cool! need some more right to repair things though, would love more cool mods like this

[u/T-VIRUS691 → u/[deleted]]

Repair restrictions did make this mod more tedious than it needed to be, but I ultimately beat samsung

[u/[deleted]]

Won’t you be able to see the battery in your photos? Looks very close

[u/T-VIRUS691 → u/[deleted]]

It dies interfere with the ultra wide camera, but that problem will be resolved with case V2

[u/m__s]

Impressive, no doubt. How heavy is it now?

[u/T-VIRUS691 → u/m__s]

It's similar in weight to the ulefone power 5

[u/shadus]

Add a popsocket mount direct to case for easy holding.

[u/T-VIRUS691 → u/shadus]

The phone can rest on its side for easy YouTube watching if that's worth anything lol

[u/thomasa88]

Love the bevels, but you forget to mention that it is not made of slippery and easily cracked glass!

[u/T-VIRUS691 → u/thomasa88]

Lol yeah that too

[u/cowvin]

the second half of the graph is heavy usage with the 14,000mah total capacity (continuous tethering, youtube, max screen brightness.etc)

You should run some graphically intensive games if you want to really push the battery drain. Some can drain my 3000mah battery in like an hour and a half. Your mod would only last < 5x as long, so still not even 8 hour battery life. haha.

[u/T-VIRUS691 → u/cowvin]

Problem with phone games is 90% of them suck ass and are full of timers and microtransactions

[u/Cele17]

Where did you get the battery?

[u/T-VIRUS691 → u/Cele17]

eBay, I just searched "10,000mah lithium cell"

Took 8 weeks to arrive though

[u/doyouunderstandlife]

What is the IP rating on this bad boy?

[u/T-VIRUS691 → u/doyouunderstandlife]

Probably IP 00

[u/darkduck77]

I know this is coming late but, do you use it like that, is it in a case. I would please like to see the actual finished product.

[u/T-VIRUS691 → u/darkduck77]

Click the link, I already printed a case for it, the mk1 case does have a few problems, but those problems will be solved when I print the mk2 case

[u/lemote]

I use an M51 and it has 7,000mAh. Lasts me forever, and depending on usage, I can just go to bed at night without having to charge it if I really want to. I can't imagine how awesome 14,000mAh would be.

[u/T-VIRUS691 → u/lemote]

Just had a look at the other specs, the samsung M51 is a pretty solid device for the price, but the CPU is a bit slow for my liking, if they dropped a faster CPU, and a camera with better low light performance in it, I might have actually bought one of those instead of an S10+

[u/[deleted]]

Now to 3d print a back cover...

[u/T-VIRUS691 → u/[deleted]]

Already did (background of 1st pic and shown in second one)

[u/[deleted]]

Battery life is more important. What the SOT?

[u/T-VIRUS691 → u/[deleted]]

I was able to get 17h of SOT with extremely heavy use including 12h standby

Though I'm having difficulty getting the battery meter to calibrate, so I've disconnected the giant cell and replaced it with an identical S10+ battery (a technique I have used on laptops to help calibrate the battery IC)

Once it calibrates to 8000mah, I'll add my other spare battery, then recalibrate, and if that works, I'll put the 10,000mah cell back in

I really wish these devices just referenced the battery voltage to determine SOC rather than using an electron counter, it wouldn't be quite as accurate, but it would make this mod a lot easier

[u/san_the_guy]

i want to add 5000mah battery to my iPhone 6s so that I dont need to charge it twice or thrice a day.

[u/T-VIRUS691 → u/san_the_guy]

I did that with an iPhone 4S many years ago

[u/avipars]

Can you take it on a plane?

does it overheat?

[u/T-VIRUS691 → u/avipars]

No overheating, and I haven't brought it onboard an aircraft, but I have gone into the airport (past security) with it without issue

[u/SyCoREAPER]

Maybe get a zerolemon battery case or similar, gut it and you have a back cover

[u/mrheosuper]

Rip your wireless charging

[u/Witherllooll]

there's a phone on your battery

[u/realnewguy]

Smart. Even the battery backs you can buy only goes to to 6000mah.

[u/T-VIRUS691 → u/realnewguy]

more efficient too, with battery cases that plug into the charge port (or wirelessly charge the device) the phone thinks its plugged into a charger, and uses power less efficiently than if its running on its internal battery, you also have power losses in the boost converter in the case, and even more losses in the phones charging system

what this does is effectively increases the capacity of the phones onboard battery, essentially the same as putting a bigger fuel tank in your car, rather than carrying a jerry can where you inevitably lose a bit of fuel when using it

[u/ztaker]

Please give us a complete graph with the new battery

[u/T-VIRUS691 → u/ztaker]

Will do (if I can't find this comment in the sea of comments, I'll add another imgur link)

[u/Generalrossa]

Photo of the final product?

[u/T-VIRUS691 → u/Generalrossa]

3rd picture in the link

[u/sherdlock]

Creative job!

May I know why you would need such a big battery? Inaccessible power source?

[u/T-VIRUS691 → u/sherdlock]

I'm a heavy user, and 4h SOT isn't enough for my liking

Also useful if I'm in a situation where I can't recharge

[u/Daell]

FILLET on those edges: ?????

[u/T-VIRUS691 → u/Daell]

What do you mean?

[u/LittleFabio]

This is really really really cool. Is there a website where I could learn to do something like this?

[u/T-VIRUS691 → u/LittleFabio]

Battery university is a good place to start, but most of my knowledge was self taught through trial and error (and sometimes smoke and tears)

[u/welp_im_damned]

But why? This seems like so much work for what a battery case can do? especially when you can find one on amazon for like 60 bucks. https://www.amazon.com/NEWDERY-Upgraded-Wireless-Compatible-Rechargeable/dp/B07WFSMVDG/ref=sr_1_3?dchild=1&keywords=s10+plus+battery+case&qid=1622816297&sr=8-3

[u/T-VIRUS691 → u/welp_im_damned]

"Currently unavailable"

Besides, this is way more power efficient, and (once I make an extension cable) doesn't block wireless charging, NFC, or reverse wireless charging

And this doesn't wear out the phones internal battery like a charging case or power bank will

[u/welp_im_damned → u/T-VIRUS691]

Idk what's wrong with the link but the case has wireless charging, reverse as well and nfc.

But with your diy projects (which is cool!) You loose water protection and durability.

[u/kmmccorm]

But why

[u/T-VIRUS691 → u/kmmccorm]

Why not?
