Hello,
Since some time (maybe weeks, I didn't pay attention), I believe my battery is totally out of calibration. When reaching about 20%, the drop to 0% is very fast, loosing percents every few seconds then the phone shutdowns at about 2%.
When fully charged at 100%, it stays at 100 for easily an hour while I'm using it (music, chat ...). It's like the calibration curve shifted by 20%.
I've tried 3 calibrations :
- Emptied battery, power off, charge until 100%, turn on then off again and continue charging to 100%.
- Emptied battery, phone turned on, charge to 100% and kept charging.
- used a calibration app (I'm not rooted)
Nothing seemed to work ... Do you have a solution to properly re-do a calibration of a P9 battery ?
Model AL10C00B389
Thanks
Nope. All I can think of is faulty battery should be replaced under warranty if possible.
Hi, it seems better after a proper calibration using XDA's calibration app. Now the decrease is more stable until 5-6%, then it goes fast to shutdown. The battery is 2 years old only (?) ...

The app is named Battery Calibration in Google store and is working also for non rooted phones.
There are a lot with that name, can you share the link?
I have similar issues with my L09-C432 P9.
There has been occasions under heavy use (like taking lots of photos on holiday) that the phone has turned off due to low battery when battery level was previously showing 40-50% - after plugging into the charger for a couple of mins the phone will power back up to show the % it was at before.
Other times the battery has "stuck" at 20% despite being used and then powered off.
Just today while playing a game, the phone was showing 8% battery - so i plugged it into a USB3 port on my laptop and it was showing 28% again within a minute or two!
The app link : https://play.google.com/store/apps/details?id=com.nema.batterycalibration
I have had exact same phenomena : shutdown at 20% when taking lot of photos and impossible to restart without plugin to a charger. Also the same quick increase of battery indication while charging. Try this app and see if it helps.
I'm having same problem, dbranded L09C432B390
Eventually the problem came back despite calibrating the battery ... today the phone turned off while taking just a single picture with a battery at about 30% ! It seems more and more the battery has an issue. It is appearing randomly but I noticed it is linked with the camera and the fact of taking pictures.
I have the exact same problem with my chinese version ( Eva- L10). The turning point is ( i believe) around 45 % remaining battery and below. The phone behaves normally at these levels ( games, web, music, etc.), until the camera app is started. First couple times the phone turned off and after starting again, it was on the previous battery level and continued to work normally ( until I open the camera app again). This behavior turned into complete refusal to turn on or to stay on after the bug.
First I believed that this is a software issue, but it goes again after the latest system update. Not sure if the Hard/factory reset will change anything ( trying to avoid that, its annoying).. Maybe the solution is to change the battery, but no guarantee for that to fix it either.. The third option is to get a portable battery and not letting it down below 50 %.
Same Issue here - on B393. First i thought that the battery is broken. But no, i have read about it in severel german and international Forums, on Facebook and so on. More and More User of the P9 have this problem, Power off by using Camera, oder totally going down between 40-20 percent. Because of this, i dont believe in a single problem with battery. There are to much users at the same time with this heavily battery bug.
Mine has started doing this...
Goes from ~25% straight to 1% then power off. Turn back on, and it says 25% for a second, then 1% then back off.
I kept turning it back on over and over untill the battery was so flat it didnt stay turned on for more than a few seconds before it shut down.
I then did a very slow charge to 100% with the phone tuned off from computer USB port and this seems to have helped a little bit, but still there is a problem.

Today I got a new phone black-out by taking just a single photo with 82% battery. I think there is no typical percent value under which the problem will come. Fortunately I had on me a power bank ... The battery still indicated 82% when I plugged it to the phone and restarted it. After restarting the phone and unplugging the power bank, I took several photos without any issues.
This problem appears so randomly ... the phone's camera becomes useless as it always has the risk to crash the phone ! Does anybody tried a hard reset or something which helped ?

I did something similar a few times to recalibrate the battery, it seemed to help but didn't took long before the problem appeared again.
Same problem here
L09
If I open the camera app having below 45% or so, the phone shuts down and only turn on to show 1% and the banner telling me that the phone will shut down in 30sec. If I plug the phone to a charger goes up to 20-25% very quick (5 minutes or even less) but obviously it doesn't last as 25%.
I did a full reset and nothing. IDK what to think, battery problem? Software issue ?
My P9 is currently away for repair
I was having a similar issue. My phone quickly went to 2% and powered off. If I then plugged in the charger, it would say 48% charged. Unplug the charger and power the phone on and it would work for a few hours. I thought it was a battery issue, so have sent it in for repair (at the retailers expense). The repair company have found a faulty charging port, but no fault with the battery.
I've never made the link between the camera app, and the charge issue, and when I get it back will test it.

Usan cargador original? Cq3.0? Supercharge?? He oído y leído que al usar el cargador cq3.0 la batería se degrada y pueden ocasionar errores de batería, descarga rápidamente o que no llegue a cargar al 100%.

ocupo cargador huawei de carga rápida, a veces pienso que eso puede ocasionar el problema... pero no estoy seguro, supuestamente no debería alterar en nada la vida de la batería.
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
Hey. I received an Android 10 update on my Mi 9 lite a week ago. Do you recommend doing factory reset after the major update?
It's running relatively fine, quicker reactions (except the recent apps menu, still lagging), but the battery lasts like 5 hours SOT. Android process is relatively high. It's 4000mah, everyone is reporting sot like 8 at least. I mean I had sot like this before the update but still. I have dark mode everywhere it's possible (wallpaper, even chrome) so I expected like 10 hours and I have possibly less sot than on my previous redmi note 5/3.
Is it recommended, in general, to do a factory reset after a major update? Concretely on Mi 9 lite?
Thank you
I do always factory reset.Try it.
I have the EU Version. Can i switch from oxygenos to coloros? If yes how?
Can I ask why you want to downgrade your phone? Coloros is terrible and limits a lot of control. I ditched it on the 9RT as soon as I could.
I think the reason might be high battery drain in the EU and IND ROM , the color OS was giving close to 7hours SOT but oos gives like 4 hrs only
I hate to tell you, but having used both the Oppo Find X5 Pro (ColorOS) and OnePlus 10 Pro (OxygenOS) - the Find X5 Pro actually has the better OS. OnePlus removed a lot of the customisation options from ColorOS to "match" older OxygenOS releases, and in the process introduced some annoying bugs like not being able to dismiss hidden notifications.
There's nothing in OxygenOS that goes above and beyond ColorOS these days - in fact, OxygenOS is the poor relative! (that's why my OP 10 Pro has been sold this morning).

And that battery drain is really awful!
I'm not sure if you can go from OOS to COS but I wouldn't bother, the amount of people wanting to go the other way is incredible.
Plus I do not buy into the battery drain issue. My first ever discharge I got a little under 11 hours SOT and I was not holding back at all.
If I had to guess I'd say you could jump to color OS, you'd have to grab a firmware, pull payload.bin then boot to Fastboot mode and flash each image to each part of the phone..
Just an FYI, ROMs are coming so if it were me I'd optimize android 12 OOS as best as I can and wait for the good times to roll in.
I will say coloros has a much longer SOT than OOS, but that is because no more than 5 apps are allowed to launch on startup so it is really debilitating since you will not receive any notifications until you open the app, but then coloros will close the app after a while and you won't get notifications again. ColorOS would be good if they get rid of all the debilitating features, remove phone manager, allow you to change default apps without changing it back, and install the default android installer.
Hi all, I have just updated my Vivo X70 pro + to Funtouch OS 13 from the Trial version option from the system update options. Once the update was done, the first thing I noticed was the temperature of the phone which shot up and all the things were stuttering to run smoothly for around half an hr straight which made me want to downgrade the OS again. But now it is running smoothly.
But I would love to know a way to downgrade it.
Also, the battery on this phone is just disappointing just after a year. It gives me around 4-5 hrs of SOT and I end up charging the phone for 2-3 times a day. Please let me know if anyone else is facing the same issue and if anyone has found any fix for the issue.
I have done the uppgrade to and i have non problem , all it just good and the best is that VoLTE is included i bought mine in april , the battery is just fine , it holds like 2 days
Damn... Mine drains even when the screen is locked. It's 33% less in the morning after i sleep. Is this normal?
Can more people give me some reviews for the battery?
Also, just got an OTA update and my phone seems to be working perfect again
how did you downgrade?
