Hi!
Im trying to solve my girlfriends battery drain problems on her P10 Lite. Im asking in this forum because there isnt a P10 Lite forum here (yet?).
Anyways, she is really struggling with the battery. I've tried to set it up with many of the same settings as me (i have a P9) but it looks like Android OS is the enemy. On my friends P10 Lite Android OS only takes like 7-8%, but on my girlfriends it can be from 10% to almost 20%. Yesterday she charged up to 100% and with 37% left she only has 3 hour SOT. That is pretty bad. I have also wiped cache.
Any ideas what can cause this?

Hi from Denmark.
I have a Huawei P10 Lite.
I no problem what so ever regarding battery life.
The 1st one you always should look at is whether or not GPS switched had been switched on.
If i remember it correctly, some apps can switch the GPS on.
You remove an app permission, fx the GPS, if you are of the opinion that the app should not have that permission.
Start Telefonstyring. It does some clean up, and will also tell you which app is using a lot of battery. Google+ is always there, but I use Google+ a lot, because I make many comments on YouTube., so it is OK with me.
Take a look around in Telefonstyring - you can fx. automatically close apps when you log out (=not rebooting) by pressing the power button for a short time. Be aware that some apps need to have stateful information, or will otherwise restart. If you choose to let the P10 lite close an app automatically you could lose progress in fx a game, or a language learning app like Duolingo, so to a lot of apps it would be a bad idea.
I also has a habit of swipe close apps I won't use for a long time (fx not before some time at the next day).
That also saves some battery juice.
In battery settings you can switch on the normal battery saver. It also have the Ultra Battery feature.
There is also the soft reset (reboot).
The final desperate one to use is to do a hard reset (wipe data/factory reset):
Search after hardreset [dot] info and search for **Huawei P10 lite**.
Thank you my danish friend! Will go through the steps this weekend
hi hope someone can help with this.
I have a huawei p9 32gb EU version
model EVA-L09 emui 4.1.1 (still on) android 6.0 (says no update available)
build number is: EVA-L09C432B182
An issue seems to have developed in the past 2 weeks (i've had it almost a year) - it has decided to close itself down when I try to use the camera. I am using the default/stock camera app not a 3rd party one. I want to make clear it does not happen every time seems (at the moment) quite random/intermittent
The battery was at 79% the first time it happened and a few days ago it was at 55% and it happened. Auto flash was on but flash not activated at the time the phone shut down.
The first time I thought I just hadn't realised the battery was that low but when I plugged it in to charge it said 79% on screen.
A few days ago when it was 55% I was able to put the phone back on after it shut itself down and it was fine/behaved normally since putting it back on - the battery appeared to drain at the usual rate. I even took a few other photos after switching it back on & it didnt shut down. I had been using camera the same morning when the battery % would have been higher & it didn't shutdown then. (& i actually took quite a few photos during that time).
Hope someone out there has an idea of how to fix this issue, though i'm thinking its maybe the a sign the battery may be failing?
I also have this issue, I think it may be a sign the battery is beginning to fail, or possibly the cpu gets too hot. (again first started happening around a year into ownership)
Under 70% battery if i take a bunch of photos it can shut down but would normally turn back on again with 20% less battery. if battery gets less than 50% then if it powers off, it may power back on breifly and then go back to the exclamation mark for empty battery and shut down.
I have tried following the guide to calibrate the battery (let it charge to 100%, turn off, plug back into charger) but it made no difference.
What did help a bit though was ensuring cloud photo apps (google photos/onedrive etc) were set to only upload photos while on wifi and charging.
Hi, I have the same issue with my EVA-L09 with EMUI 4.1.1 build EVA-L09C900B182 bought in october 2016. Shuts down after shooting few photos/videos and can't start it again without plugging it. Once plugged, the battery level seems to be the same as before the shutdown. Seems to happen with any battery level.
If anybody can help solve this, that would be great. I can't decide to change the battery for the moment without certainty that it would fix this issue.

To all of you...unlock bootloader and update firmware. Maybe your issues will be solved. Its a conflict and not a battery issue
Sent from my EVA-L09 using XDA Labs
Any resolution?
I am having the same problem with my L09 and the P9 camera app. Was on Nougat so rolled back to MM in attempt to fix. Also tried a faster SD. No luck with either.
No such issues with other camera apps from Play Store, but they don't use both sensors.
Anybody resolved this problem definitely yet? If yes, how?
Thanks.

I have the same problem since the last 6-9 months.
However I noticed that the problem occurs when I make photos when I'm outside and the weather is windy/damp. I never had the problem when shooting photos inside, always outdoors.
The solution is indeed connecting the phone with a charger (or portable battery) or wait for a couple of hours.
It could be a problem with the battery but it is strange that the phone is ok again after charging a couple of minutes. If it was moisture this idid not yet vanish in just a couple of minutes. Maybe a sensor which is not working ok (or the firmware is not resetting/reading it correctly) ?
I'm thinking of sending my phone into repair for this problem, however I think this is a difficult to identify problem because it does happen randomly (as it seems).
I'm having the same problem, after battery goes under 50% It drains fast, bellow this it only takes 30min of use to shoot down, taking a few photos just makes it drain even faster. And when plugged to the charger it suddenly gets up to 40% . I tried everything software wise with no luck. I bought a new OEM battery planning to change it this week, then I'll post the results.
I am facing the same problem L09C432B395. I observed its somehow being related to cold temperatures outside in my case - it happens only when walking outdoor and the phone is in my hand for a while - so its probably cools down. And than when pressing the camera button I see the message "waiting to sharpen the photo" and then beeeep! battery down to 1% and phone shutdowns. Regardles the battery level.. happening accidentaly and randomly, but only once a week.. and only when taking phone outdoor in a winter time. I did factory reset, re-installed the latest ROM etc but the problem persists. Might be some conflict between battery state and temperature read error?

Update: I change the battery, everything back to normal. I used a OEM battery, screen time is +6h with moderate use during the first row cycles of battery use from 100% to 10%.
Hi all together. Faced the same issue up times (Huawei P9 EVA-L09C432B395, Kamera App 4.1.1) with battery in good state 46 to 76% and taking a picture caused draining it to zero at a moment. Sitting down immediately. BUT only if flash ? is set to bulb-light ?! Tested it several times. Normal (auto/always active) flash is ok - but not bulb-mode...
So, that's obviously the reason - but where's a solution? ?
Some Huawei officials here at xda? ?
Same problem here and without solution yet ... camera causes phone to shutdown and battery indication goes crazy.

Experiencing the same issue on both P9 we have and getting very annoying would be glad to see if is there any solution of this.

These are my exact symptoms - combination of cold and camera gives false battery reading and shuts down phone entirely. Software update hasn't fixed.
I have same problem
EVA-L09C55B383
it's the last firmware
emui 5.0.1
android 7
at 50% battery i make a photo with flash and the p9 turn off.
to turn on i need connect it to recharger.
it's very very impossible.
i think to send it to customer care.
have someone resolved this issue?
i ask to huawei on facebook. i wait a answer.
Any luck with Huawei support for any of you?
Hi,
I'm having the same problem. It's amazing how there's no information at all from Huawei about this issue... it's frustrating. I was planning on buying a P20 during this year and give my P9 to my wife, but if she can't use the camera it's useless. And I will not buy another Huawei if they don't do anything regarding a problem like this one...
Did any of you had any positive experience with Huawei Customer Care?
Thank you!

Did you try yourself any search for custom ROMs ob XDA for Huawei P9?!
https://forum.xda-developers.com/p9/development
I tried Huwawei customer care.
Their best offer was factory reset of all firmware!
Install updates doesn't fix.

Even when connected to charger!!
Even when the phone is connected by USB to my computer and charging, if I open the camera the battery % starts to drop like 1% every 4-5 seconds!!
So the battery is being drained faster than what it charges.
I close the camera and it starts charging again.
Huawei, I was very happy with this phone, now I'm constantly in fear of getting out of battery in the middle of an unknown city while taking photos!
Hey guys. Massive problem here. I have stock EMUI 9 9.0.0.163 installed and I seem to lose 15 to 20% battery overnight when left idle. Gsam and BBS show nothing major or out of place so not sure what is keeping my device awake. Also I have only my main apps set to be managed automatically by EMUI and 90% of all my other apps are manually managed to not auto run/secondary launch/background etc.
Anyone got any idea as to why this is happening? I have factory reset several times and a few days ago my mother used this phone with only WhatsApp and Pinterest installed and she still experienced the same as me.
You had better make a factory reset..
Hi guys, since emui 9 and 9.1 my SOT it's about 4 hours or 4.5 hours max,sometimes even 3 hours if i played a lot, I usually play games for a couple of hours, spotify youtube and instagram and the max i can get is 4 hours (From 100% to like 20-25%)
When i don't play and i use only instagram youtube and watch streamings i get more SOT but like 5 hours max
I've looked into the battery details and nothing seems strange (With gsam i found that i have some wake lock that drains battery like 1-2% at night) and during the night i lose like 5-6% battery with wifi on and bluetooth and gps off
Is that normal? Do you get the same SOT?
Also my screen lights up for no reason at all very often, i disabled the feature that can unlock the screen from lifting
I got emui 9.1.0.328
Do a Factory reset. Just to be sure that is not software related.

Still same SOT
what's yours
@Danyy29
This such a subjective subjective.
Give or take you should be seeing around 1.5-2 days total up time and around 5-8 on average SOT.
But and I'll quote this as it's a massively expansive word for this subject.
"It Depends!!!"
Signal strength.
Routine
Battery efficiency
Age of device
Apps installed
Amount of apps installed
App usage
Device set up
Switch choices (WiFi/BT etc)
Firmware
Model
Variant
These are the tip of the ice berg.
You cannot measure two devices as they're just so different, even though they appear the same.
When I was sick one time. I stayed in bed playing Zelda the wind waker on the dolphin emulator.
During that weekend, I managed to get 14 hours 45 mins on a OnePlus 5.
Same situation 1 year later on my p20 pro, 17 hours 47 mins.
I have all this in a thread with proof.
Great signal
Only used internet
Few messages
Few calls
Great WiFi
Didn't leave house
No mobile gaming
That being said... 9.1 is not as efficient as 8.1 by a country mile, it's an apple style nudge to get you to buy a new phone even though you don't need one.
Hope this helps.
If I had to give you a top tip, it would be too lighten the load, no Facebook. No Snapchat, Instagram, any apps with ads, get rid. Any apps that run all the time! Get rid.
No excess apps, get rid. Get drastic.
Then test
Internal short or the battery is defective. Take it to a huawei care center.
With Accubattery the life it's like 90%
I bought this device in november 2018
I don't think it has problems that much
It doesn't get overheated
I get a maximum of 40°C when high end gaming
So idk
but ty for advices
Hi,
I recently bought a galaxy s10 and I'm wondering if the batterylife is rly so "Bad" or if there is something wrong with my Software.
I have a screenshot attatched. This was a Day with biking (Navigation in background) and only liddle screen on time.
Before I had a xiaomi Mi 9t pro and i was able to use the Phone for two days without charging. Even sot of 7 hours or more.
Why is my s10 not Even lasting "one day".?
Seems to me Q is the culprit
Are you on Android Q yet? My S10 used to reach 30-40+ hours of battery time on P (mostly web whatsapp and regular phone calls, no games at all, see pic).
After upgrading to Q, juice can't even give me 30 hours. As I see it, in my case Q is clearly the culprit.
SOT is not a valid metric for me, as I'm always on web whatsapp -- lots of use, screen always off.
I am Android 9 with the AT&T firmware G975U model. I can get around 25 or 26 hours out of it before I have to recharge it.
Yes I'm on Android Q.
I think it's due to aod and Google Service.
With the Installation of gms fix Module of magisk the betterylife got better. Also im using the adaptive battery Management setting and disabled aod. Now it's only on when I received a message, which is fine for me.
Now im getting through a Day, but still it's not that impressive compared to other phones (one plus and so on)
