While using camera app, my pixel 2's battery drop 1% per minute.
Is this normal ? Does anyone else facing this level of battery drain ?
Bought pixel 2 a week ago. Screen on time is mostly below 5hrs
I've never measured the drop rate, but it is normal for the battery usage to be super high while the camera is operating. It sucks a lot of juice on any device to keep the screen illuminated and process images.
Could it be the HDR mode that's constantly taking photos in the background just in case you capture a shot?

Or maybe you have location saving enabled... That could drain quickly too.
Yes, I have very high drain whilst the camera app is 'live'. Take a few photos and it's always the top draining foreground app. I have considered this 'normal'. I think the processor and/or sensor is working hard doing whatever it has to do. I was hoping this drain would stop in later firmware that uses the image processor in the Pixel, but maybe it's not yet being used or have similar power drain.
Other than the camera app, I have very good battery performance out of my Pixel with my usage model. AccuBattery reports a 6h54m SOT full battery time estimate but my phone never does 100% - 0% cycles, so this is only an estimate.

I know there's a battery thread but I wanna have a more detailed comparison of battery drain so that users can check against their own stats please post how much 1% of drain gives you in screen time and specify some things like:
*bin chip: get the info by entering the download mode
*Wi-Fi or cellular1
*brightness
*sync gmail/push mail etc
*screen resolution
*location on/off and settings
*any saving mode
*other settings you think would impact the battery life.
I know it's time consuming but let's be thorough for a minute and please no cheating
We can do by usage as well like: audio/video /gaming/browsing
I'll start
Browsing: 1% drain for 5 mn SOT
Gpu 4 small cores 6 big cores 6
4g
50% brightness
Syncing 4 gmail accounts and Twitter notifications
Fhd+
Location on battery saving on with Wi-Fi scanning
Limiting CPU to 70%
Edge light on
5 apps notifications on
Video: 5mn 1% drain
Watched 1080p video on YouTube
Same settings as above

Update; I have exchanged my s8 for a new one and this one looks promising as I get 10mn SOY with same settings as previously used in browsing scenario
Better chip bin on this one?

Only on GPU as this one is 4 vs 3 but something was definitely wrong about the first one either a bad battery or something else.

Hello,
My used S7 came in yesterday from Amazon and everything has been fine except the battery. The battery drains very quick. Earlier today the battery went from 100 to 80% in around 20 minutes and the phone was hot just on the home screen and browsing the internet..
The phone came with G930U software and I flashed it back to G930R4 which is what the phone is originally, then I flashed it back to G930U XAA because Oreo came out for it earlier today.
I disabled Always on Display, device scanning, etc. I even ran ADB and removed Gear Vr and bloatware apps.
Here's some screenshots:

I don't know why the Screen is using so much battery. Any help will be appreciated!

That's so weird... Why is my screen so high compared to yours?

look at your SOT (Screen On Time) and also i used no auto brightness and set it up eith 0% brightness + lowerung resolution (720p instead of QHD) and using app callef Pixel Battery Saver to turn off some extra pixel. and don"t forget to make it black.
See hidden screenshot below for system information.

Long story short, I've been noticing sudden system shutdowns recently at normal battery state of charge levels. Like ≈40% or even a little above 50%, for example. I have Battery Monitor Widget installed and I see battery current drain spikes just prior to each shutdown, like ≈2000mA or over 3000mA shots. This for sure is caused by some application, I use many at once but…
Mmm, the recorded voltage levels are pretty low, 3353mV or even 3082mA for the biggest drain shot. Now that I think of it and being the battery expert I am, this totally looks like an unhealthy battery problem, when charging the voltage also ramps up high and early. This means abnormally high connector and/or battery internal resistance. The terminal was bought second-hand and in superb condition, but now I guess that was due to the original owner having it inside a rubber cover case with a screen protector attached. Main problem nailed.
Carrying on with the abnormal battery power drain spikes, any of you noticed some application going rogue with power after some recent upgrade? Telegram maybe? Saw Telegram on top of the battery draining apps recently, and I do not honestly use it proportionally that much. Chrome browser usually is at the top but with a lower percentage to time ratio.
Buff! Did I fully answered myself?
Wellp, if some of you is willing to add something please do so.
2021/01/01 edit: The problem was indeed due to a weak battery, fixed it long ago.
I have Xiaomi 12s ultra, i was extremely happy with battery life.
One evening camera was recording while charging by mistake, when i wanted to check, it was 35>56 in 40 minutes, and phone battery charging was very slow because it was unbelievable hot. Did i just killed my battery?
I think battery is draining very fast after this. Can you share usage stats?
Is there any way to undo this, like draining battery to 0 and charging to 100?
Before this day i was using 20-80 charging method to save my battery. All efforts are gone i guess.

Yes, phone batteries don't like charging and draining at the same time. However, it could just as easily have burnt out or permanently deteriorate the quality of some electronic component.

Yeah i know. I hope camera sensor did not get any damage.
Yesterday i get about 5-6 hour screen on time, 14 hours without plugging with wireless internet only, %45 left. How much did my battery lost of its capacity with that incident? I guess my battery was better. Thanks for the chip in 12SU it didn't go on charging. It could have exploded.
I made a mistake to my battery.
I'd like to see what did i lose, can you share your battery usage screenshot.
What i did bad to my battery :
Charging while video recording by mistake, did i kill the battery?

Ask other users to post their battery usage screenshot remains very relative, indeed for absolute precision, it would be necessary that you use the same rom and especially with the same settings and that you use, for example, Chrome on the same duration, same for other apps.
Note that Wifi consumes more than data for certain uses.
Wi-fi Vs Mobile Data Battery Drain: Do Mobile Batteries Drain Faster On Mobile Data Than On Wi-fi?
Mobile data drains more battery than Wi-Fi because a continuous cellular connection needs to be maintained constantly with towers quite far away.

Seems like there is not a big problem. I'm sure it was bad in the first days. Xiaomi 12s ultra has a battery management chip, which is said to be repairing cells. It is doing what it says i think. Well done Xiaomi engineers. 5:30 SOT from morning to night with lte most of the day is simply amazing.
