r/OnePlus13R

There was 30% battery left before I put it in charging

So this is the sot am getting . Idk how everyone else is getting that good. Someone recommend me to use suspend cache but unfortunately didn't work.

🥲

The sky doesn't turn red everyday.

16.0.3.800 update says two sets of bluetooth earbuds can be used to listen same audio with your friends. Does it work? Also after this update any battery drop? Should i update? What do you think?

I wanted to buy this case for my 13r but I am confused because it is showing the picture of 13 but in the text it is written 13r so what should I do?

When i try to unlock picture from private safe gives me this error. I already have "My files" installed. When i click install button doesn't work. Anyone to fix it?

I have a OnePlus 13R (CPH2691) running OxygenOS 16.0.8.300 (EX01V30P01).

I recently tried the most hyped battery "calibration" method that many people recommend:

• Drain the battery to 0%

• Let the phone switch off automatically

• Charge it while powered off for 1 hour 30 minutes

• Turn it on

After doing this, I noticed several strange issues with the built-in battery statistics.

1. Why is "Used since last full charge" showing 14–15 days?

Instead of resetting after a complete charge, it kept showing:

• 14 days 15 hours

• 14 days 16 hours

• 14 days 17 hours

• 14 days 19 hours

• 15 days 11 hours

How is this possible after charging the phone to 100%?

Shouldn't this counter reset after a full charging cycle?

2. Why is Screen-on Time already several hours immediately after charging to 100%?

After unplugging the phone from 100%, the Screen-on Time didn't reset.

Instead, it already showed values like:

• 4h 50m

• 5h 06m

• 5h 17m

It later increased normally, and currently I'm at:

• 31% battery remaining

• 7h 49m Screen-on Time

But why didn't the Screen-on Time reset after a complete charge?

3. Why is Screen-off Time decreasing instead of increasing?

During the same discharge cycle, the Screen-off Time changed like this:

• 2h 57m

• 2h 54m

• 2h 55m

• 2h 42m

• 2h 30m

• Currently: 2h 09m

As far as I know, Screen-off Time should only increase, not decrease.

Is this a bug in OxygenOS?

AccuBattery vs OnePlus Battery Stats

I'm also using AccuBattery Pro, which currently shows:

• 100% → 31% battery

• 6h 40m Screen-on Time

• 19h 29m since unplugging

Meanwhile, the built-in OnePlus battery page shows:

• 7h 49m Screen-on Time

• Used since last full charge: 15 days 11 hours

The two apps are reporting completely different battery statistics.

My Thoughts

At this point, it feels like the built-in battery statistics on OxygenOS are inaccurate or not resetting properly after a complete charging cycle.

The phone also reports 100% Battery Health, but when the battery statistics themselves appear inconsistent, it's difficult to know how reliable the battery reporting actually is.

Questions

• Is anyone else experiencing this on the OnePlus 13R?

• Is this a known OxygenOS 16 bug?

• Is there any way to reset or fix the battery statistics properly?

• Have you noticed similar inconsistencies in Screen-on Time, Screen-off Time, or "Used since last full charge"?

Any insights would be appreciated.

I am not a techie by any means, consider my digital tech knowledge equivalent to that of a grandma. So now that's said, I'm honestly alarmed by the fact that my screen off time is so high, higher than my actual screen itself.

I am a very casual user, I use my phone for watching videos on YT, Gpay, Maps, Occasional AI applications like gemini or perplexity and on my off days I doom scroll on soc media (this day that the stats attached depicts one such lazy day of the week).

I've never done any CPU intensive tasks like heavy gaming or editing, anything as such. My battery life and drain is honestly not impressive either, roughly 10 to 15% on casual usage per hour.

It's been less than a month since I purchased this device from oneplus official store.

Can someone please provide some insight as to why this is happening, could this be the reason for unusually high battery consumption, what are the solutions, quick fixes that I can do from my end to mitigate this problem.

Even if the recommended solutions are a Lil tech savvy, I wouldn't mind trying it by learning to do the procedure through YT or tech blogs, It'd be great if you're willing to share the source as well. Thanks in advance, I also apologise for the horrible formatting, I'm using the mobile application.

After every OOS 16 updates performance increases but my 13r still gets warmer in 30mins gameplay of CODM
