P) high battery drain - Huawei P9 Questions & Answers

hello everyone, here is my problem - in last couple of week i'm having really big battery problems (to the point i'm thinking of smashing my phone to the ground ) I take my P9 of the charger and it says it is at 100%, after only few min it drops to about 90%, and when i open some app (facebook atc) it freezes and when i try to turn it on again it says 0% battery!! when i hook it up on charger it takes 20 mins to charge to 1%, and when i turn it on again it says anywhere between 40% and 100%!!! Freezing most commonly appears when i turn on my camera and take a picture, it snaps then freezes. Tried with the factory reset it didn't help.
Please anybody!!!

Most likely the battery has worn out. Is it still under warranty?

Same here, sometimes camera apps freeze and then i will reboot it. After reboot, phone shows 5% power and then force itself into shutdown. The battery actually may not empty as told by phone, when i start charging, it shows more than 5% and phone actually have juice to run longer.

Sounds like a battery replacement to me. Have to tried installing AccuBattery or anything similar to check the battery health?

It's not the battery causing this fault

I have replaced the battery in my P9 and it still gets a power drain when the camera is operated. This usually occurs in low light environments. If I immediately turn the phone back on it starts up with maybe 20% battery, which then drops 1% a second and gets hot. This is with a brand new battery fitted. I conclude there is a glitch with updated software. Hopefully Huawei will read these posts and correct with future updates.

Not the battery
Try removing your sd memory card. I think a malfunctioning sd card was causing issue of battery drain during camera use. I can't explain the full science behind this, but my p9 phone has been fine since I removed the sd

Might not be your power bank, try using BBS to find out
After a day i can confirm is NOT the power bank. since this happened in the past 3 days
i used Airplane mode all the night to see if some a is Wakelock my phone and got just 3 % of battery usage with the power bank attached, so i manage another test since BBS told me is Android System RIL or something like that.
Second Test: Disabled 3G+ Connectivity for 2 hours and enable just GSM 2G and just got 4 % dropped ( i make a few calls and used whatsapp so is OK), i think is 3G becuase where ilive is outside the city and recently we got a heavy storms (causing shoutdown of the nearest anntena) i have low reception rnothing and 3g running so i think my phone is using more battery trying to acquire more signal and 3G support.

Sudden Battery Drain - 50% to 4%

Hi guys
S10 5G (SM-G977B) owner. Been using since launch. Exynos version with latest update - G977BXXS2ASJ7.
Always recharge to 80% battery to maintain health for lifespan of phone. Avoid leaving it plugged in overnight.
This looks like a bug that I have noticed following the last major update which introducted a bunch of Galaxy Note features such as Samsund DeX for windows.
Phone will literally hold 4% charge for hours. Picture attached. Is there a fix for this or is this a known issue? Couldn't find anything online with all posts about high drain touching on the usual suspects (always on display, 5G switched on, performance mode, screen brightness etc)

Have you tried a factory reset? Or ever done a clean install using Odin files with CSC_OMC?
I'd suggest factory reset as this seems like a glitch with your device. It's definitely not a known issue with the 5G or any S10 variant.
Hopefully it's not a battery or other hardware issue that's apeared. But the reset will help rule that out. It's a good idea to do it once in a while anyway.
Also, not charging overnight, and only charging to 80%, is saving you next to nothing on long term battery life. Unless you plan to keep the phone for something like 4 or 5 years, you'll see absolutely no difference in the life of the battery over the next years or two by doing that. You're best to charge to 100% and get the full 100% charge during the day.
Thanks mate. No factory reset yet attempted. Always painful re-synching all the apps and 2fa services so generally try to avoid. I have attempted Davlik cache wipe but that made no tangible benefit. Accubattery reporting 85% battery health and this is despite my battery babysitting ways (3774mAh actual vs 4400mAh design)

Catastrophic Failure?

I've had my SM-T810 (Tab S2 9.7, wifi) for four or five years now. A year ago, half of the screen began flashing brightly if I tried to use it on low brightness. To solve this, I turned up the brightness a bit and used the app Darker.
Over the last few weeks, things got much much worse. The tablet required more and more brightness to avoid flashing, it would stutter when playing videos, and responsiveness was slow. Every so often it would lose WiFi connection when my other devices didn't have trouble connecting.
Today, there has been some type of catastrophic failure. I was watching a video, when suddenly the video stuttered, froze, and the tablet became completely unresponsive. None of the buttons worked at all. It would not turn off. After about 15 minutes, the screen began its old flashing routine...and then something new happened: the flickering was joined by colorful lines, and about five minutes later the tablet shut itself off. It had become quite warm around the volume rocker/card slot area.I can't turn it back on, but if I plug it in, it shows the battery percentage. The tablet has never gotten wet, and it hasn't been dropped recently. Any thoughts? Thanks in advance!

Is the battery indicator dimmer than normal? Normally I would just assume at least the screen is bad, but since the charging indicator seems to work? Perhaps you should try download mode? Odin over fresh firmware? (You will lose data on the tablet though)
No, the battery indicator doesn't seem dim. I'll have to try your suggestions. I'm starting to think the motherboard is bad, and that would help me determine if it is or not.

Maybe some files in EMMC corrupted? Then if ODIN works it might get it back to life.

Question Important battery drain not understood

Hello all,
I recently buy an OPPO find X3 pro and I'm really annoying with battery life. I could not succeed to reach more than 3h of SOT and would like to know if it's normal.
I already perform a factory reset without success (back-up and restore from a PC). I don't know what to do know.
I've installed GSAM and allow "more stats" with ADB and notice that Android System is the most battery consumer but I don't know if it's normal. In idle, power consumption is acceptable 3-5% overnight but as soon as use it I see battery level decrease rapidly.
I've also a Galaxy watch. At the begining I saw a high drain from "watch plugin" but I authorize it to run in background + no battery optimization and it seems Ok now.
Does anyone have a solution to help me solve this problem ? I really like this new phone btw (after my old OP6T) but the battery is really awful...
Thanks in advance !
Below some screenshots :
2h20 of SOT only and 35% left

Hi,
I had the same problem. Did the following:
1) Reset to factory settings;
2) Restarted the phone;
3) went to Settings > Battery > More Settings > Optimise battery use > set all apps to Auto-Optimise.
If you want to test if you probably have a faulty battery you shoud do the following:
1) charge your phone till 100%;
2) restart the phone;
3) disconnect it from the charger;
4) switch on airplane mode;
5) leave the phone unused for 8-10h.
If the battery drops bellow 93%, you have a faulty battery that needs to be replaced.
Bare in mind that this processor is very power hungry, nevertheless OPPO should have predicted it and pack with the phone a, at least, 5000mAh battery.
Hope it helps!

Question Massive Battery drain on idle. Battery went from 70% to 45% overnight with all background apps closed.

I have no idea why this is happening. It's been 2 weeks since I purchased the phone. The screen time is showing 1hr 23mins but the phone was idle at night. Is there a fix for this issue?

Something is keeping your phone from deep sleeping. When the display is off it can be in one of two states, one is the phone is still on, CPU is running but the screen is blanked out, this lets apps continue to work, for example sending an email you've just sent then turned off the phone. Then after a little bit more time the phone goes into deep sleep, this sees everything frozen so nothing is running and the CPU is off. It should be in this deep slate state most of the time you are not using the phone. What can happen is applications take a wake lock, and stop the phone from going to deep sleep, and over many hours that really drains the battery.
Restart the phone and see if it is now okay. Consider what applications you have installed recently that might be causing the issue.
