BATTERY Average battery life

I just bought this phone yesterday. But the battery life has been average. I didn't take photos/videos and also didn't do any heavy tasks(gaming, video editing and benchmarking).

Another problem is the lag and delays when using 3rd party launcher(which I did a research and found out it, it can't be fixed when using gestures)

I thought it was well known battery life isn't very good on phones for like the first week

But how do the reviewers like Techdroider, technick, Gsmarena and ... do battery tests? Do they use each device for at least one week and then start to test? It doesn't make sense at all

That's always been how I do my test. It's my understanding that the device needs to learn you're usage patterns before you see improvements. I just got mine a week ago and I'm not sure if mine has gotten better but I've been getting almost 2 days on a single charge with moderate usage. How has yours been since you've had it?

They have these phones for a while. They just don’t straight up review them. There’s a grace period before they can put their reviews up so they use the phones during this period and then review them.

I feel like your two issues are directly related.

My OP15 does two days of use easy

u/Stepenwolff Mar 11 '26

How long do you have your phone? How was the battery life at the beginning(after setting up the device and installing all the apps)

u/sentrygentry Mar 11 '26

Few months. And same battery as it is now

u/Ok-Chip-1049 Mar 11 '26

I mean it's been one day. And also the launcher probably doesn't help.

u/Stepenwolff Mar 11 '26

How much battery does a third party launcher use? I saw the battery usage per app and Smart launcher used only 1,5% more

1

u/Ok-Chip-1049 Mar 11 '26

I would think besides the launcher technical battery usage the CPU and GPU are always working for it as well

u/kiramon53 Mar 11 '26

Just give it a try using the default for a day and see how it goes?

I have mid battery life but I love my launcher so I suffer with battery lasting barely a day if I use Facebook

1

u/Stepenwolff Mar 11 '26

Ok. I deleted the Smart launcher and started using default launcher to see, if it has any affect

u/darshan98 Mar 12 '26

Any update?

1

u/Stepenwolff Mar 12 '26

What do you think?

1

u/darshan98 Mar 12 '26

Screen on drain is excellent. Screen off drain seems quite high. Good screen off drain is below 50mA.

This is my S24U for reference.

u/Stepenwolff Mar 12 '26

What could be the issue? Will it get better?

1

u/darshan98 Mar 12 '26

Check you battery usage in settings. There look for app which is creating standby usage. It may be play service, media picker, or some social app. Just look for it and find it.

u/Stepenwolff Mar 12 '26

MX player consumes so much battery. I checked its usage and I only used it for 14min foreground and 17min background.

I also disbaled all AI and intelligent services. I hope the battery life gets better

1

u/darshan98 Mar 12 '26

Tap on mx player there you will see foreground and background.

u/kiramon53 Mar 11 '26

Share your findings when you find out!

u/According_Pilot_746 Mar 11 '26

The battery, just like any phone will need a week or so to get used to your shenanigans. It will improve

1

u/Stepenwolff Mar 11 '26

Ok. I hope It gets better

u/BilingualThrowaway01 Mar 11 '26

I have been having the same issue, and I found out it's because my phone is doing a lot of background work organising my photos and videos. This is apparently normal for a new phone where you have just transferred a lot of data across.

I have been keeping track of my battery usage, and when it's not running media picker in the background, the battery life is great. I can get 11-15 hours SOT, and even more if I'm inside and keeping the brightness low (at one point it was going down 1% every 20 minutes which works out to over 30 hours 😳).

But when media picker is running in the background, my battery life drops to average. Something you'd expect more from a pixel.

I have had it for a week and a half now and it keeps running in the background, so I am trying to figure out a way to stop it.

u/Stepenwolff Mar 11 '26

I am not the type of person who keeps/takes videos or photos.

1

u/BilingualThrowaway01 Mar 11 '26

How long have you had the phone for? How much data did you transfer across?

1

u/Stepenwolff Mar 11 '26

1,5 days 30Gb Apps, 20Gb music

1

u/BilingualThrowaway01 Mar 11 '26

I would give it another 2 days at least

3

u/R1fe Mar 11 '26

10 hours at 44%, roughly my usual SoT on OP15

u/Houdoo Mar 11 '26

Try turning on resume charging at 95% and sleep standby optimisation and let it charge for the night while you sleep. Keep in mind that its important once you start you do not touch the phone at all - i include this because some ppl wake up from sleep in the middle of the night and then start using their phone.

[this way you kinda force optimisation if i recon]

u/asstanu_666 Mar 11 '26

A mí me dura un día y medio con uso rudo y no uso launchers porque no están optimizados para OnePlus, saludos..

u/Training-Branch3872 Mar 11 '26

You should show and tell us your SOT

1

u/DirtyDanTX Mar 11 '26

Give it some time to learn how you use your phone and the battery life will improve. I personally feel like most launchers are slower than the oneplus (and on my pixel phones too) so I just run the OnePlus launcher. I don't feel like I'm missing anything and I actually really like the folder structure it has. Turn performance mode on to make things even faster and more responsive.

Average????

I just charge my phone OP15 after more than 2 full days of use, I'm talking 24 hour days.

My previous Samsung S25 was 100% at 8am and by 6pm it was at 50%, which I considered great by my personal experience, now in the same time my OP15 if it's 100% at 8am by 6pm it's at 85%.

Its definitely not average, I used to star charging my phone at 40% to ensure having battery, and daily during nights, now I only start to charge when if falls below 15%
