I have been experiencing this problem for 2-3 months. I charge my phone to 100% and when i reboot my phone (for some other purpose) battery level drops to 40 or 60% and this is extremely annoying. Usually when this happens i shut down my phone pull the battery out and put it back. After powering on the battery level is back to the correct value. But now it is not working. The battery level stays there and decreases. Well it only happens sometimes but still when i need my device it is low on battery.
I searched on the internet but most people using galaxy s2 were facing this and they recommend doing a battery calibration which i didnt find useful.
Any solution?
I have uploaded the battery usage in case it is needed.
Guys, just asking for those already running EMUI 5 build on Huawei P9, have you guys face problem such as battery drain very fast? My P9 battery draining very fast until I have to charge OR bring my powerbank with me all the time. Is it the latest build caused the battery run fast? or there are something wrong with my phone?
Start by checking third party apps, my battery is great, it's the first phone I've had that I don't really think about charging, it gets through the day every day with heavy use.

don't use beta build if u are not willing to receive bugs
Check the battery logs for imonitor. I had high battery usage by this process - it may be that the beta has higher analytics so that's using more battery (and therefore should be fixed for full release).
Do you have root?
If you do, install that: http://www.onexuan.com/battery/
Or, pro version (you know what to do if you have root): http://www.opgpro.com/
If you don't have a root, play a bit with: Settings\Advanced Settings\Battery Manager\Protected Apps - Put "some" or all to sleep when screen is off...
Same here... Even with power saving mode enabled
Hi had issues with the battery on mine but I think it was down to being rooted and some other software that was on it. Since flashing it back to stock the battery life is so much better. Easily gets through a day now.
Can Phone Manager be silent battery killer? It closes all apps (except protected) when you turn off screen and you have to relaunch them again. I've read in multiple sources that you shouldn't be closing manually apps because in newer Androids RAM management is great and closing/opening again apps will consume more battery that just leaving them be?
P9 battery is damaged after 6 months here. Also a small spot appeared behind the back of my screen. Send it to warranty. They said the battery bloated inside and was pushing in the screen. Replaced both battery and screen. It seems there is a huge battery problem with all p9....
I'm running EMUI 4.1.1 and the battery drain is real.
Left it at 100% charge when I went to bed yesterday and when I woke up this morning battery percentage had already decreased by 12% (88% charge left). That's insane.
Hi guys,
I keep having weird battery behaviour which led me to believe, that the battery is not properly calibrated:
When charged to 100%, the phone usually stays at 100% for a few hours depending on usage. Around 40% however it keeps dropping 1% every 2-3 seconds until after a few minutes it is drained completely and switches off.
Did anyone else notice that kind of behaviour? (Some guys on Reddit are facing the same issues)
And does anyone know a fix except waiting for a custom rom?
Thanks and all the best.
Jay

Same here, I didn't notice the battery after 40% but the phone stays at 100% for a really long time, I played Honkai Impact at max setting and it still manages to stay at 100% for an hour, mb it's software issue, I'm on 12.5.7 Global btw.
I didn't experienced that kind of issue. 12.5.13.0 EEA here.
you have to calibrate the battery.
- discharge the battery until the phone turns off
- with a slow charger (10 / 25w) charge the mobile OFF
- once it reaches 100% (1-2 hrs) wait another 2 hours.
- Power up and test.
This method usually solves this problem, it is important to use a slow charger and only use the 120w one when it is really necessary. It seems that some batteries have not been properly calibrated

Thanks, I'll try to do that with a slow charger.
After it reached 100% still keep the phone on charge for the next two hours or just wait two hours to power up?

Still keep the phone on charge min 2 hours or more (ex. When you sleep) next you can turn on

It does fix something, now my phone can stay till 1% without turning at 3% like before, thanks.

For me viper4android it's much better if you use wired headphones. I tried to use Dolby but it's not the same.
I'm on 12.5.13.0 EEA, same problem. Phone stay at 100% for hours, then when power dropped to 35-30% weird thing happened, it keeps dropping 1% every 2-3 seconds until after a few minutes it is drained completely and switches off.
Then it takes 5-10 minutes to start again
I will try to calibrate the battery tonight
Hi, I was facing a similar issue.
I have used 3 chargers. 120W (stock), 10W (samsung), 65W (Anker). I was worried about my battery life, so decided to ditch the 120W charger which was also not giving me a good enough battery life, considering its a 5000 mah phone.
Im not paid by anker or something, but I saw a major difference between SOT compared with stock and samsung charger as well. I dont know why this is working out so well, but im getting 7+Hrs SOT easily, on heavy usage. AndI have been getting consistent results from the past week since i switched to anker. I genuinely dont know why or how this is working. But if it works, it works.
Im assuming due to the 120W quick charge, the battery calibration gets messed up. But idk how to explain the longer duration of SOT on the anker charger.
Ps. I dont use 5G

yes, I don't think you are very far from the problem. I also think that charging the mobile at 120w spoils the calibration of the battery so I use it only at specific times. I use a standard 15w charger (approx 2hrs)
3 days later It looks like calibration sorted my issues. Now battery behaves as is should.
So calibration is very recommended if battery plays up
I recently purchased this cell phone, and I am experiencing this problem. I have disabled almost everything, and uninstalled blotware. Should I calibrate the battery to improve battery drain?

Please read my reply in this thread, that will extend the battery drastically.
im facing this problem with this phone as well but also something else: after the battery drops to 18-20% it then discharges very very quickly to a point where in a matter of 5-10 minutes of use it's down to 0%. is this normal or is it another one of those side effects that their trashy fraudulent scamming xiaomi battery measurement causes?
will another rom fix these issues or are we stuck with them in this phone i rapidly regret getting?
I'm also facing the same issue, below 25% to 0% it drains like a liquid, I attached the screen record

mine got fixed (at least for now) by calibrating the battery (leave it to discharge and turn off - try to turn on again until it wont - charge to 100% with phone off) i'll see how long this lasts and update
Ya i did it for now it is fixed might be a temporary fix. I'll post here if it happens again
Same problem at first month, 100 - 99 became shorter and shorter while charging cycle increasing.
After updating to MIUI 13 heavy battery drain issues. Did clean flash of fastboot rom still battery drain still no solved.
In MIUI 12.5 used to get 9-10 hours SOT with light usage. Now getting 6 -7 hours.
Is this for me only or everyone? Any way to fix the drain
I did not notice any battery drain but the fast charging speed was reduced and also the phone was not at all heating up when fast charging
I can suggest you to turn off "google services" or if possible, dissable it. This might help you increasing the battery backup.
