Battery calibration issue - Huawei P9 Questions & Answers

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 (?) ...

Which app... Without being root?

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.

[Q] My Awful Battery Experience

The battery life on my NC is absolutely horrible. I average 3 hours unplugged, 1 hour if I'm using it. It doesn't seem to charge up all the way -- after plugging it in the light on the Nook cord is orange for about 10 minutes then goes green even though the screen still stays "Not enough power to turn on - Try again in 15 minutes".
I've tried using software like juicedefender and other battery mon apps that are supposed to be able to predict when you're going to lose your power -- but they appear to be useless. Often I'll get the "Your Battery is Getting Low" message at the very same time as the "Shutting Down" dialog appears -- almost like there was a very sudden dramatic drop in available power.
I am beginning to wonder if it's the result of faulty hardware.
Has anyone else experienced problems like these? Or should I restore back to stock and send it in for warranty?
That definitely sounds abnormal. I'd probably restore it back to factory and if it's still acting like that, you'll know it's not due to any modifications.
Yeah, I second that. Mine drains pretty quickly, I go from 100% to about 60% in a day with normal usage. I use Wifi Auto Toggle to turn Wifi off when the screen turns off. So far I have to recharge every other day or so. But what the OP has going on sounds pretty extreme.
What ROM are you using?
What programs have 'keep screen alive' do you run?
How bright is your screen?
Screen/wifi burn most of the power in this - so minimizing them helps battery life considerably.
I had one game (HexDefense) that prefers to run in maximum brightness and burned through the battery very quickly. Nook was the warmest I've ever seen it and the temperature on my battery monitor actually moved for the first time ever.
SO if you're getting 3 hours doing nothing, that's bad. If you're getting 3 hours running a really processor/graphic intensive game, that's good.
If you can get it back to stock and still have low battery life, consider talking to the manufacturers about it.

You really question this? Something is wrong with your NC, cable, or charger.

HTC ONE serious battery draining problem

Hello, i have my htc one a couple of weeks now and from the first time i noticed paranormal battery drain activity!
So first i tried to turn everything off it didn't help, more analyticaly:
Energy Saving Mode = On
Beats Audio = on
Brightness = 1st of the three brightness modes
Wifi = off
GPS = off
Location Services = off
Accounts Sync = all off
HSDPA = on and off after done using data
Apps running in the background = i closed each and every one immediately after done using them
Blinkfeed = completely off
Then I tried to reset battery memory by completely let the battery discharge and recharge overnight twice, i have seen no improvement.
When i surf or facebook i can see the battery meter to drop down 1% almost every 2 minutes or so, some times less with the above mentioned settings.
Also i have noticed that in standby with everything off there's still significant battery drainage.
I kept the best for last, just 10 minutes ago while connected on my computer via usb cable, fully charged at 100% with green led on top for more than an hour i just did a reboot, and after the reboot with the usb cable still connected i saw the battery 99% ?????? After what, a reboot and still connected to the usb and charging ? WTF?
Device info:
HTC one 32 gb bought from Vodafone Greece
android version 4.2.2 stock
software version 2.24.401.1
kernel version 3.4.10-g445d072
On top of that, it seems that my device also has the blue ghosting noise camera bug on low light enviroments.
My emotions are like; I love and hate this phone at the same time.
I'm afraid using my phone's capabilities due to serious battery drainage!!
Any thoughts ?

Try this app to see if you have an app installed that is draining your battery.
My first One had a bad battery - would only last for half a day.. the phone I have now lasts a day or more.

With stock? Holy Damn that's crazy! I get 2.5 on a regular day. 3 with continuous use. Should I do a factory reset?
I get 5+ hours screen time but not if it's a day full of voice calls.. all based on how you use the phone!

it depends on how you use your phone and how much time it has been turned on. If your phone has been on for more than 24 hours then 3 hours of screen is fine. But yeah maybe you should do a factory reset and install gsam to monitor your battery stats and the apps that are sucking your battery. I have noticed that facebook chat drains the battery too fast.

I think you live in a sunny place, if you do than 2.5 hours is sort of normal at full brightness, if you want 5 or longer you need to set the brightness way lower but I think that sort of dimishes the beauty of the screen, enjoy it on auto-brightness

What nonsense?!
70% of my screen time is medium. I rarely use my phone in the sun.
I usually get around 2.5 screen/<14 total hrs. That's not normal? My phone's not set up right? Yay!
Or maybe it's the facebook. My auto sync is off, but I will disable the FB apps and see how that goes.
I actually do have GSAM, and it tells me that my kernel uses ~25% of my power. Android system is usually ~15%. Is that normal? If so, I may try a backup/reset.
Screen uses ~10% of power and main app is Chrome, with little to no Maps/Voice in a day.
A quick report after factory reset seems like that my battery is somewhat normal
1day 7hours and I still have 34% remaining
Use: half standby half normal use
I have the Dev Edition 64Gb One and I'm getting just 12 hours! I have autobrightness on, Greenify taking care of all the apps I don't use so frequently, not using maps/location services. I noticed each time I enter recovery, I have like 4% less than what my phone says and if I turn it on I have now what the bootloader said! Weird, and I was shocked to see this when I red a lot of people were having fantastic battery life.
Also, as I'm so lucky, mine has the blue/red thing in the camera, and a small gap in the top. It seems I got the All-(Problems)-In-One One..

Try with InsertCoin + Elemental kernel, with no pocketdetection or sweep2wake etc. and the recommended undervolting in the aroma installation
That gives me like 5.5 hours of screen with the phone turned on for 20+ hours and wifi: 6+hours, all of this with an average usage
hello again I noticed a rather peculiar thing regarding battery drainage.
couple of days ago when I reported that my battery was somewhat normal I had my phone charged with energy saving mode off I charged this way two times since the factory reset. Everything was normal I was able to get one+ day of use. Yesterday though I charged my phone with energy saving mode ON and I immediately noticed abnormal battery drain as before.
Can anyone with battery drain problem try to fully charge their phone with energy saving mode off and post their results?
I have a strong feeling that there is a bug or something.
My problem is, the phone is fully charged. i disconnect the charger and a few seconds later the battery is between 96% and 93%. I connect it to the charger, charge it back to 100% (led green) disconnect it, and the same happens again.
I already let the Phone discharge to 1%. The same happening again.
Someone any idea? thx
Same problem here, just sent it in to HTC for camera repair, got it back. Then battery problems. Sent it back because of the battery, still crappy. 32GB Unlocked. I get 10 hours at most on idle, everything off.

Go to setting>mobile data>network mode select something else than LTE and reboot your phone. Then select back Lte and reboot your phone.I had the same problem. I found this on other forums and this helped me a lot.
I have a HTC One 32 gb Three UK.
I have exactly the same problem with the high drainage.. before I could get easy 5-6 hours screen on throughout the day. now it even don't lasts a half day.. no change in my apps or settings/kernel.. really weird problem. I think it has to do with the hotness of the Phone and the purple camera fault. Don't know what to do anymore!

[Solved] Fast Battery drop from 100%

First off, i know ALOT of people have this issue, and have brought it up across several topics and custom rom pages, but i dont think theres a specific thread for this.
After unplugging my phone from the charger at 100%, it drops to 98 percent immediately, within seconds. After that to 96, then 94, and then it stays steady and starts discharging normally. Basically, within a minute or two the charge drops from 100 to 94 percent without any use whatsoever. This happens across multiple roms so its not a rom issue.
Ive tried wiping the entire phone, running it down to 0% and recharging, recharging it back to 100% once it hits 94%, but the problem keeps recurring.
Is the battery starting to lose its life? What are some ways i can test to see whats causing this? Or better yet, a way to fix this?
For example, is there an app that can tell you the capacity of the battery at any given time, so i can check if it actually drops mAh between 100% and 94%?
Oh yea, and i normally take the phone off the charger right when the green light turns on and it hits 100%, so its not caused by trickle charging.
Any tip is appreciated.
Unplugging and plugging it back in right after it hits 100% causes the phone to start charging from 95% again, happened twice in a row now.

im not sure if its a battery issue or a system issue, it seems like the battery isnt getting topped off properly since plugging it right back in causes it to start charging from 95% again. It seems to me that it never actually reaches 100%
Same here with AOSP or Sense Rom, after i load the One over the night, plugged it off (with 100%) and turn the scrren 2 minutes later on - it loose 2 %.
In beginning i never had this - sometimes my mobile was running over 2 days without charging (Slimrom) now over 1 day running is rarely.
I think its the battery, the companies want the people buy new stuff year by year and now the time is correct with the new HTC M8 release..

thats prolly just a delay because turning on the phone uses quite a bit of battery, so the 2% is probably a result of that. One or two percent after charging is explainable, but anything more than that (ie 4-10%) then theres a problem.
same problem
I have the same problem...I charge the phone until 100% and turn off , next i turn on and lose 10% ......
this problem start with rom 4.4.2....i change to other 4 roms and the problem not go away
Now i try to downgrade to 4.3 to test

Found a way to fix it: turn off fastboot, fixed the issue for me.
Additionally, theres a calibration method that comes directly from HTC to fix this issue.
Let the phone charge while on for at least ten minutes, turn the phone off while still plugged in, and hold power, volume up, and volume down for two minutes. The phone will reboot several times.
Didn't have to do this since turning off fastboot did the trick for me.
How i turn off fastboot??
Here i can find calibration method from HTC?

I thought this was normal. it happens to me too but i thought it was because when the phone is at 100 while charging, it stops charging till it gets to 95 while still reporting 100. so if the charge is at 95 but it displays 100 and you remove the charger it would drop to 95 after a minute.

T810 Screen flickering when battery is low

Hi. Anyone have screen flickering when battery is low and immediately before shutting down? Large vertical bars.
I'm unsure if this is a software glitch of an hardware defect. It shutdown around 9% or 10% battery remaining.
Yes a few of us have reported / experienced that. No real workaround so far except to avoid single digit battery levels.
I returned one unit and had the same thing happen on the second. Both were updated to 5.1.1. What version are you on?
Hummm do you think is defect and it should be sent to warranty or is it ok? since the battery isn't completely depleted i'm unsure if it correctly shutdown or if it hard shutdown, possibly causing data loss or other issues
I have it on original and exchanged 9.7 units and my wife has it on her s2 8.0. All are on 5.1.1 I'm wondering if anyone on 5.0.2 (shipped rom) has seen this happen?
Hello. I have this problem as well! Has anyone been able to solve it?
This happened to me last night around 5%. I just turned it off and took it to the charger.

a me succedeva nel vecchio tablet (samsung tab s 8.4) ho provato a reinstallare il software ufficiale ma niente da fare...!:confuso:
Shame here, Galaxy tab s2 t715

My phone turns off at 5%

My phone turns off at 5% every time!! The phone is working great. It doesn't turn off randomly but everyday at 5% it turns off and tells me to plug in the charger. After plugging in the charger the phone keeps on showing the battery logo and it turns on after pressing power button a couple of times while the charger is plugged in. What could be the problem? Or is it normal? I remember when i was on stock, the phone used to turn off at 2%. Im using Chroma Rom.

Seems normal to me. The battery condition becomes slowly worse.
When possible don't discharge below 20-30%.
haven't seen one of these in a while. people used to talk about battery calibration, but i'm not sure if it is a real thing.

The battery on this phone is being let to go very low in the normal 100 - 0 range as it is. As it ages the low end will drop quicker and quicker. The qhd oled they used on this phone is really not nice for the battery. You can buy a new one on aliexpress.
Fixed!
