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.

After a difficult update with Kies I was able to upgrade to Gingerbread.
Everything seemed to go well the first time then I found drain battery and slowing down on the system.
So I decided to make a simple wipe which reported the phone as fast as at first, but the battery still has problems.
In one night from 90% it was completely drained so today I decided to use 'Battery Calibration' made from user 'marosige'. This time in 5 hours I lost 30% of battery life using some sms, internet for 15 minutes, and playing cut the rope for 10 minutes. More or less.
However I have to see if the battery loses all of a sudden like last night which is the biggest problem.
All of this is not normal have you any advice?
Thanks in advance
Hi Fattox,
Dont worry your socks off I flash Roms quite often and this requires me to calibrate the battery. Sometimes with certain Roms I find the battery may drain quickly the first time and then things get better.
You say you have calibrated so that means the app you used should have deleted the old battery stats from your systems file. In saying that if you follow these next few step you should be ok (unless there are other issues causing the drain)
1. Make your you drain the battery fully until phone dies and can't be turned on by pressing the power button then....
2. Plug in phone and keep it off until battery is fully charged. Don't take it off charge as soon as it says full. Just let it go for about an hour more or so to ensure it's at capacity.
3. Turn phone on and use as normal until dead...
Providing there are no other issues causing the battery drain you should find your battery usage to be satisfactory. Remember to turn off wifi and gps when your not using them as well as maybe turning your screen brightness down. Anything that uses less power the better....
Hope this helps.
between the recalibration with the app and your point 1, I had the same problem: during the night the battery loose all the energy.. so strange.
All this after I upgraded to Gingerbread.
I'm going to test all this week then I'll spend my warranty.
Hello,
I have an Ativ S and about a week ago the battery started to drain very quickly - about 15 to 20 per cent an hour.
I do not have wifi, bluetooth or gps on and usually the battery lasted 2 -3 days but now I need to recharge twice a day.
I thought that this was maybe caused by a program so I reset my phone and reinstalled only a few programs, but that did not work.
1) Is there any way that I can see if an app is draining my battery quickly?
2) Could this be a hardware problem? If so, how can i tell if it is the battery or the phone? I think that my warranty has expired, so returning it is not an option.
PS It is on GDR2, no interop unlock or any other tweak whatsoever.
Thanks
I'm not going to say it's flat-out impossible for an app to drain your battery that fast in the background, but it's not far off. If you want to be really sure, though, enable Battery Saver mode immediately after unplugging the phone (at full charge) and don't use it. Battery Saver prevents all background app activity, so there won't be any apps running and therefore they *cannot* be affecting the battery.
I'm pretty sure that, given the rate of drain and the fact that it persisted through a hard reset, you have a hardware problem. The good news is that it might just be a bad battery - that is a thing which happens, and it's even fairly common on batteries a couple years old - in which case it's a good thing you have a phone with a user-replaceable battery! The way I'd test that is to swap your battery into somebody else's ATIV S and see if the problem persists. If so, it's the battery; if not, it's your phone. Alternatively, you could just buy a second battery and see if that helps.
One other thing to check: if the battery really is still working and the phone is draining it that fast, it'll be dissipating a lot of energy as heat. Does the phone stay abnormally warm while the battery drains like that? That would be a sign of a problem with the phone or the OS, as opposed to the battery itself.
Oh, and I'm pretty sure there are some battery diagnostics and charging statistics located in the Diagnosis app (##634# in the dialer). I forget the code for them but I have all of the codes written somewhere; alternatively, you could do some searching. You could compare the reported battery capacity there with the expected (design) capacity.
I reset my phone again, installed only Viber and till so far, the battery drain seems to have disappeared (or at least improved).
Some users on wpcentral reported that they had major issues with battery drain caused by Whatsapp.
I used Whatsapp for quite some time but never had any problems( till now).
Maybe the last update caused this, i dunno...
Anyway, thanks for your answer.
I will see how it goes and I will let you know.
I just sideloaded 5.1 and I use Battery widget pro.
After 5.1 when I unplug my device this widget tells me I have 8 hours of battery left.
Even on 5.0 my battery seemed pretty poor but at least it would be at 12 to 14. I just don't get how it can be that bad.
Sometimes after turning it off then back on the battery level will adjust to something higher.
Is this possibly an app issue draining my battery? Anyone have any tips suggestions?
Best,
Ryan

Let it run for a day and see how much battery life you actually get. Maybe let it drain all the way out once and recharge it to 100%. I know when I ran custom ROMs on my Nexus devices, it would take a couple of days before the battery stats adjusted and displayed correct info. I once had a battery meter say 1% for about an hour before my phone died after switching to a new ROM.
How did it go? I noticed massive battery draining wakelocks on 5.1, related to phone and location. Without Xposed I don't know how to control them.
Cheers!
Hello, I hope all of you are well and I can get a reply or suggestion from you guys for this.
I have a new P20Pro. Bought it on the end of October.
The battery life is absolutely great with almost two full days of usage.
The issue I got is this.
When I am using my phone and it comes on the last 10% of battery it staets droping by 2-3% immediately. So it will go from 10 to 7 and then 4 and then 2 and immediately shut down.
The whole thing would happen to 3-4 mins in total.
When it gets to 2-3% it says it will shut down in 30secs and never goes to the last 1% or 0%. The other thing that bothers me, connected with what I said before, is that when I connect it to the charger when it turns off completetly, usually starts charging from 2-3%, almost never starting from 0. Today for example turned down when it was 4% and started charging from 12%>
I have tried almost everything, recalibrating the battery, doing the charging cycle correctly, wiping the cache and factory resetting it and also chenging the settings but nothing seems to be working.
Any ideas please ?
What you describe is usually a battery problem on older phones and a new battery remedies that. Mine us also in a bit of hurry ti switch off below 15% so I make sure to keep my juice always relatively high. I might take it for replacement of battery in a few months to have a new one after 500-600 cycles [emoji4]

Mine starts shutting down at 6% I think! It's caught me out a few times, thinking I had at least another 20 minutes.
I can't complain about the battery life though so no big deal really. Conversely when I unplug from a full night's charge it can stay at 100% for ages whilst using it.
I'm guessing either calibration is a bit off or EMUI is really going the extra mile to protect your battery from being damaged by draining too low.
almost 2 full days usage?
man I barely get one day, the battery is being drained quite quick
I just switched from OnePlus 5T to P20 Pro, and the battery life of the first is way ahead (and recharges much faster)
maybe there's a problem with my p20pro?

Hi!
Follow the below steps.
Phone manager>Do optimise>tap on battery icon>Optimise battery usage. And dont let any apps to run in background. Using auto start manager you can control the apps which are running in the background.
and please post the battery usage details and check which app is consuming more battery & kill the apps which are consuming more battery
Hopefully it would help.

Hi Thanks for your help
I will definitely do it and will keep yous updated
Meanwhile, let me bring something else: My phone doesn't supercharge. Even when I use the original cable + charger (and plugged straight into the wall) it doesn't fast charge. Doesn't display that it is being supercharged or something and it will take about 3 hours to finish charging.
This is a brand new phone which I got last week.
I used to have an OnePlus 5T which recharges pretty quick but this P20 Pro, although it is a beautiful phone, charges like my old Moto X.
Anything else I need to setup in order to enable supercharge?

Download Ampere from the app store and see what the charging rate is.
When almost empty I get a rate of 4200mA ish.
The more it charges the lower the charging rate.

When I use the original chargers from Huawei, it won't get past 1800mA
Then I went to visit a friend who got a Mate 20 Lite, he has a fast charger and I tested his in my p20pro and it went to ~2300mA (and then it displays in my phone "fast charge"). However, if we use on his phone, it will go more than 3500mA
The supercharger won't come by default in the box? I'm asking because when I got at home I checked the output of my recharger and it shows 4.5-5v -> 2A, it seems it isn't the fast/super charger
Hi there! What you have described with the battery percentage going to 3% and then immediately to 0% is an issue on ALL Huawei phones. I had previously owned a P10 LITE, a Honor 7C, Huawei P20 PRO and Mate 20 Pro. They all do this. I suspect it has something to do with the reserved battery percentage . It shuts down quickly so that it can keep 2 % and not drain completly. I do not know the benefit of this but all phones do it, however Huawei's software implementation is so poor that it actually displays wrong percentages. It has nothing to do with the battery being old. They do it straight out of the box and ufortunately do not know of any solution to this.
Just an update:
I had a chat with the store which sent me the phone and then they sent me the correct charger with supercharge.
Now it works well and on Ampere it shows 4.5A

Goto Phone Manager touch power saving->Optimize.Phone Manager will rapidly identify apps or features that are rapidly drainning the battery.Touch the Optimize button net to each or feartures to disable it and start saving power.You can touch Recover to re-enable the app or feature.When you remove an app from the protected apps list,your phone will close the app automatically when you turn off the screen to save batterry.
Hello!
I've been experiencing worse battery life on my Nokia 8 since Pie upgrade, I haven't installed any apps nor services...
Note that the battery improved -but not as good as Oreo- after calibration using an app...
Are you experiencing the sane issue? Or should I further investigate?
Thank you..
yes
Same here. I got 12 hours screen on time once on oreo but now, it is a dream. Battery drains fastly due to background services. App restriction doesn't work as well as oreo's restriction. So, this situation causes battery draining. Also there is a weird thing i've faced, battery drains quickly from %100 to %95. I am waiting for Maintenance Release impatiently.
is battery life on oreo really that good?
I'm using pie since day 1 and never got more than 7h sot and 1.5 days.
My battery life is dire since pie, I was impressed with the battery in the 8 until this update, I cant even make a day without having to charge. When I say day I mean from 7am to 10pm as its left charging overnight.
Before pie I could quite happily last 2 days between charges, I'm not a heavy user, initially I thought I must be using the phone more. But I'm actually using it less just so it makes it to the end of the day!
Somehow it's worse again today, dead by 4:30!
Basically just checked phone to see the time, around 10 minutes of faffing in the morning, rebooted it before charging last night incase sonething was using battery. Madness!
For me, I've given my phone a factory reset before I installed the Beta labs/initial final(V5.110, December 2018-January 2019) build. Despite that, I did notice my battery life taking a hit when running this iteration of Pie. I was at most getting not more than 5 hours of SoT on average. And I do use my phone a lot throughout the day, the camera, web browsing, videos and social media. Meanwhile on Oreo, I can get 6 hours on average no problem. Sometimes even 7 hours if I'm lucky.
After updating to V5.140(February 2019) with Adaptive Battery brought in, I seem to have gotten back my average SoC just like when my phone was running Oreo. Running 5-6 hours on average. I'm not sure if Adaptive Battery has anything to do with this since I did notice the improvement immediately. I also disabled some of the Evenwell crap before updating to V5.140, so that may or may not have an effect.
If apps restricted didnt work then try manually restrict each app go to ur up hold it then info Then choose battery from there change background restriction
Ifaced this problem in beta when iwas sleep and wake up morning my battery was almost below 20 percent but i manually restrict all apps and its working 100 percent ?
Sorry to heat that. Have you tried installing some apps like better battery stats to see what exactly is saying up your battery? If your phone is rooted consider installing ForceDoze from f-droid and maybe WakeBlock to regulate some wakelocks that may be the cause of your terrible battery life. I have been able to get great battery life using the latest put version. See screenshot below from a few days ago.
I know that this is old thread but i have solution which i use with my nokia. change default launcher to another lightweight. This works and my battery feel better.
I should of updated, battery went back to normal after newer updates.
However, biggest thing for me, using DNS666 Ad blocker has seemingly doubled my battery life, might be a combination of just gotten bored of the phone or blocking all the ad's saves battery, or a bit of both, its also made the phone feel a lot more responsive overall, i'm using Squarehome as my launcher so maybe that was affecting the battery before?
Maybe which update can fix battery life? I rooted my phone and can't download latest update.
