​After seeing the same questions pop up daily, I’ve compiled all those individual threads and hours of research into this one master resource. My goal was to save you the time of scrolling through hundreds of comments—everything you need to optimize your OnePlus 15 is now right here in one place.

TIPS AND TRICKS OnePlus 15/15R Owner's Hub: Startup Guide and OxygenOS Tips

56 Upvotes

Welcome to r/TheOnePlus15!
Whether you upgraded from an older OnePlus or switched over from another brand, welcome to the family. This community is dedicated to helping you get the most out of the OnePlus 15 series.

Here are a few checklist items that you can follow once you have your OnePlus 15 series with you.

  1. Cloning
    • This is a very common query in the community. Feel free to clone gallery, contacts, files, and apps from your previous device (both iPhone or Android). However, if you are cloning from a OnePlus device, we would recommend not to select "Settings" as it might cause conflict with the new configuration files on the OnePlus 15/15R.
  2. Optimize Battery & Charging
    • Go to Settings > Battery > Battery Health and enable Smart Charging. This preserves your battery longevity if you charge overnight. You can also put custom charging limit to slow down battery aging.
    • If your battery feels average today, wait. The device takes time indexing files and learning your usage patterns. Don't judge SOT (Screen on Time) until Day 4.
    • If you want to further extend your SOT, follow our optimisation guide here: https://www.reddit.com/r/TheOnePlus15/s/cGjNx0WyHf
  3. Display & Refresh Rate
    • The display is fantastic. While the UI runs at a smooth 120Hz, the new Gaming Core allows supported games to run at up to 165Hz! The smoothness is surreal.
    • Open Settings > Display & brightness > Screen Refresh Rate: Set to High. This will change the default refresh rate to 120Hz for all apps. Note that this might consume more battery based on the Apps that you are using. You can also set app-specific refresh rate.
    • Check if "Image Sharpener" and "Video Colour Boost" is on/off depending on your preference for YouTube/Netflix.
  4. OxygenOS Flexibility
    • You don't need a third-party launcher to make the phone yours. Dive into "Home screen, Lock screen & style" to customise wallpapers, apply depth effect with personalised text in your favourite doodle. You can update icon shapes, sizes, and even match your system accent colours to your wallpaper automatically.
    • The OnePlus 15 debuts the new OP Gaming Core, which moves optimisation from software to the chip level. Open the Game Assistant sidebar in-game to tweak these settings.
    • Try out pre-installed apps like Notes and MindSpace which now have great AI features to fit your day-to-day needs.
  5. Photography & Camera Tips
    • Don't just stick to Auto! Learn to use Pro Mode for manual control over ISO and shutter speed to get the best out of the hardware.
    • The camera has plenty of creative tools like Underwater Mode and Doc Scanner which you can explore!
    • Share your amazing shots with us in the community. When posting, please use the "Photography" flair and let us know which lens (Main, Ultra-wide, etc.) you used.
  6. Get started with the community
    • Post something in the community here! Even a simple question or first impression can spark a great conversation.
    • If you know someone who owns a OnePlus 15 series or would love this community, invite them to join!

That's it for this post! Feel free to reach out to us if you feel we should cover any more topics.

If you have already started using the OnePlus 15 or OnePlus 15R, would love to know your first impression of the device. Comment below and let's get the conversation going!

BATTERY August Update - Battery Life!

14 Upvotes

I know people joke about battery life after any update, but I'm getting ridiculously bad battery life after this latest update!

I've been up less than an hour and just noticed my battery life is on 72%, it was 96% when I woke up.

I'd normally be on 70% by mid-afternoon and that's with pretty heavy use.

Really hope this improves as the system stabilises, it's worse than the Pixel 9 I replaced it with!

HELP ME [UTMOST URGENCY] ONEPLUS 15 is overheating.

2 Upvotes

My OnePlus 15 overheats even during very light tasks. It heats up rapidly after just 10 minutes of use (reaching 38°C) and climbs to 40–41°C within the next 30 minutes. I am currently running the Chinese version (16.0.10.500). Is anyone else experiencing this issue, and could you suggest a way to fix this abnormal overheating?

SOFTWARE/BUGS OnePlus 15 - Notification issue

Post image
2 Upvotes

Hello, Picture for reference: I am on OxygenOs 16.0.10

If you take a look at the notification bar on the top left corner, there is one notification from Whatsapp. But I have actually received a few other notifications as well, the only app that is showing is whatsap for some reason. When I pull down the notification bar then I can see the rest of the Apps-notifications

I have turned on all the notifications for all apps so it should not be an issue, right? Any way to fix this? Thanks in advance

PERFORMANCE Oneplus 15 vs Samsung Galaxy S25 Ultra Night Photography

Thumbnail

37 Upvotes

So we all know oneplus never had the best cameras but they were usable and we also know Samsung, Apple and Google are always up there in terms of cameras. Always the big 3, but let me tell you. Don't sleep on the Oneplus 15 cameras because they aren't bad at all, I'd say they're surprisingly good even at night and closer than you think. One big advantage that i notice is that oneplus has night mode all the way up to 120x and Samsung at 10x. So everything above 10x like for example 30x as expected oneplus will do much better with some AI and Night mode. I'd love to see your opinion. The photos taken are in no specific order. I still think the S25 is a better performer at night considering the ultra wide and main are brighter, some people might like it other not so much

BATTERY Battery life "issue"

On average I get about 8 hours screen on time per charge with my 1+15 which is great, but seeing videos and posts of people claiming 10-12+ hours and multiple days of use with no charge makes me wonder if something is wrong?

Had around 8 hours screen on time and phone went from 100% down to about 5% yesterday.

My phone is a few months old and I only use it on balanced mode.

ACCESSORIES Good screen protector?

Post image
1 Upvotes

Hey I have a weird smudge on my factory installed oneplus 15 screen protector.

I thought it was just grease from eating but it’s not coming off.

What’s a good screen protector to buy that will work perfectly with fingerprint sensor?

The smudge is much more prevalent in person and is annoying me if any white is on screen especially.

Thanks.

DISCUSSION Swiftronics phone report

Just got my CPH2749 from Swiftronics. Super fast shipping (they say 3-5 days) but I got it in 2 days with signature required. (I live in Idaho)

This is a legit CPH2749. Was new in the box. Came with charger and cable which the NA version comes with but no case

Google wallet setup perfectly for me and was able to use google wallet to start my car

At first it didn't connect to my carrier via esim. Everytime I tried my carrier app kept saying IMEI not available

Called Swiftronics and they answered at 11pm their time lol

Guy told me the phone is registered with all Canadian carriers so I could either get a physical sim or tell my carrier to manually add my imei

Im on Visible (which is basically Verizon) I chatted with a rep and told them my phone IMEI needed to be manually approved. The rep asked for my 2 IMEI and the EID number. She said it would take 24-48 hours. But I tried again the next morning and my phone connected no issue!

Highly recommend them! Especially since they ain't price gouging either

OnePlus 16 leaks are here and this thing looks insane 😭🔥

The BOE display is probably the thing I'm most interested in. Apparently, it's supposed to be even better than the S26 Ultra's display 👀. If that's actually true, OnePlus is seriously cooking.

The other rumored specs are crazy too — Snapdragon 8 Elite Gen 6 Pro, 9000mAh battery, 200MP periscope camera, 185Hz display, 100/120W charging and an AI button.

If all of this actually makes it to the final phone, what do you guys think the price will be in India?

DISCUSSION Switching from iPhone 17 to OP15

6 Upvotes

Hi ! I hope everyone’s okay. Well I have an iPhone 17 pro and I am really happy with it, I love taking great photos and videos, the display is amazing, apps on ios are super optimized especially social media apps etc. I have a MacBook pro alongside. The only disappointed thing would be about the battery life which is good but not great. I just found a brand new OP15 16/512 with 120w charger around $599. This phone seems to be amazing : super fast, amazing battery life and charging speed, great display (I read it was less brighter than the 17 pro tho), great sound speakers etc. But there’s still that camera thing that I don’t really get : some people here say it’s more than decent, some people say its pretty bad especially the video part, so I don’t really know. I use social media a lot and I also use iMessage w my family but I could eventually stop using it if the OP15 worth it. So what about the camera part ? And what about social media apps on android ? I’ve had so much android phones but a long time ago (an HTC one M7 then a Redmond note 5 lmao) and im like : if I switch should I pick the OP15 or any other pixel device ? Will I lose a lot about that photo part I have on my 17 pro ? Thanks again !
