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.

Hi guys, I've flashed the 4.2.1 ROM by albinoman887 and only when the screen is on the lowest brightness it uses a lot of battery, really quickly.
Thread can be found here
When it's on standby the battery lasts for about 7 hours, but when it's on it lasts for around 45 minutes. Please help
I've tried
- Wiping battery stats
- Calibrating battery.

Your horrible cell signal is at least part of the problem. Your phone is constantly pinging the towers looking for a better connection. That's a serious battery hog.
You may have the wrong radio for your carrier. Or you may live in a dead zone for your carrier.
Also, is this your first battery cycle after a full wipe? I get results like that for the first discharge cycle after install. But then it becomes fantastic. Drain the battery all the way until the phone shuts off. Then charge it using a USB cord on your computer (not the standard power charger) for an hour past when it says 'full'. The slower USB charge can help to give it accurate voltage readings while charging so it doesn't stop charging too early. See if that helps.
The battery on Albino's 4.2.1 is pretty spectacular for most people, so the good news is that this is probably a fixable issue on your end.
The signal was when I'm out and about, most of the time I have 3-4 bars on HSDPA, I may do a full 24 hour charge or get a new battery
I have this problem too.But if i flash last build,baterry life is good.
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.

In mid-January I've bought a Redmi Note 6 Pro Blue 3GB / 32GB. My idea was to use it mostly for music (Spotify and Google Play Music) and video (Netflix and IPTV streaming) as a secondary phone. I was so happy with its battery life and overall performance in the first couple of weeks that I even considered using it as my main phone. However, after less than two months of very irregular use, the phone's battery life dropped quite drastically.
I tried a factory reset yesterday, but the issue remains. AccuBattery estimates the battery health at 19% of the advertised 4000 mAh. Do I have a defective battery? Because this certainly does not look like a software issue - I also tried removing all the apps I could to ensure there is no battery hoarder eating away my battery's juice, including most MIUI software through the adb tools I've seen recommended in a thread here and no luck. It's probably even worse than before. What should I do?
I'm running the latest MIUI Global 10.2 stable 10.2.2.0 (OEKMIXM). No root, bootloader is locked.

^ One and a half hours of battery life after charging it up to 100% post-factory reset. 15min after this screenshot, the battery is at 9%. How is this possible on a phone purchased less than two and a half months 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.
