well... I think is "normal" is it got stuck at boot or restarted itself... that "normally" happen when flashing another rom: you have a #% when doing TitBu and those stuff then you flash a rom and when finally bootup you got [usually] -#% and since it was from boot to boot it can't get the correct graph... or at least thats what I think

not normal i think... i've seen thing like this once - with older version of Zeus (don't remember which one exactly). When i had SoD, after i remove battery (warmer than usual) and put it back, the graph was similiar.

its either a self boot or an sod.... ive experienced alot of these myself =P.... the screen goes black then when you press the power button repeatedly goes very bright then it reboots then the battery chart gets cut off like that.....
for my part i think its mostly cos i install and uninstall alot of apps (even those that are not supposed to work for our ob) so im pretty sure its not a rom problem cos i dont see anyone else talking about it....
i posted sometime back on another thread abt my phone always losing 3g and rebooting itself (after what seems like the 3g hangs) but that problem, (although not for its intended purpose) has been solved for me by using the FD off patch that Huexx posted for his rom.
it could also be (im guessing here) due to not clearing old data (ie battery charge levels) after flashing a different rom... i read somewhere that someone has an almost similar problem coming from froyo to custom rom. something about the battery charge remembers the charge and discharge levels from the prev rom and cannot charge/ discharge properly with the new rom causing the erratic power levels.... its something like... in your picture, shows that it rebooted at 90% and went to abt 80% cos in actual fact you have used your battery to 80% just that the system failed to update this in the background hence it forced itself to reboot to get the proper reading again... again for this last part im really guessing....

by the way my phone has not any problem sod fc or restarting etc. everything is normal except battery graph.

GT N7000-misleading battery indicator on stock JB

Hello everyone!
So i am having a problem with my N7000.I flashed it to JB with stock ROM the german version of it from this thread.
http://forum.xda-developers.com/showthread.php?t=2241106
I had JB before i flashed it with this ROM but i used KIES to update my N7000.I had that problem since i updated via KIES.
So let's start:
1.I am having a very fast battery drain,here is a pic showing that for only 2 and a half hours my phone is down to 73%.

}
2.The battery indicator is misleading.IDK how to describe it so here is a pic:
Now the thing here is that The green battery bottle when it is 100% it indicates as the bottle is completely green.Now on the n7100 and the S3 and S2 when the battery reaches 90% the green goes down by one line,as for me it goes down at 94%,so i don't see why does it do this.
PS:After flashing my phone i did a full Factory Data Reset.My phone was never rooted or modified.I would really like to see why is this battery indicator misleading.
Thanks everyone in advance .Hope i will get some help here.
Anyone?
80+ views and no one can help?Seriously....
Beacause its not a problem. Maybe?
The battery drain is quite normal specially if the first or second charge-discharge cycle of a newly flashed Rom..
The indicator is quite normal also.. but you can change that on systemUi.apk editing.. or just flash a custom theme..
<<<The CRACKS on my NOTE shows how often it KISSES the FLOOR>>>
Battery indicator is ok, but fast draining its not normal. Try to make factory reset again, this stock rom is scrab.
He has more than an hour of screen on time for 27% of batt...
Estimatedly if you multiply that to 4 times it will give MORE THAN 4 HOURS SCREEN ON TIME which is decent enough..
<<<The CRACKS on my NOTE shows how often it KISSES the FLOOR>>>
The stock battery indicator considers the entire icon to represent 100%.
If you don't fancy that, there are numerous mods in the Themes and Apps section that allow you to customise your battery indicator.

Problem with kernel

Can anyone help? I just got my Nexus 6 a few days ago and have already had a lot of problems. Battery draining fast, randomly turning off, phone battery "dying" at 45% etc. I heard the Franco kernel could fix this so I flashed it via fast boot (storage wasn't mounted in recovery so I couldn't do it that way. But in any case the fast boot flash went through and the battery started draining normally so I thought all was good. I even took a screenshot just in case.

That was until my phone randomly turned off and when I turned it back on the battery was draining super fast again so I checked kernel and here is what I believe is the stock kernel reverted back on its own
I don't know what causes this but it's happened twice and not sure how else to proceed.

When I got my N6 about 19 months ago the battery life was not enough for a day.
I got a better battery life as follows.
a. Deleted apps I hardly use.
b. Switch apps to use black/dark themes. Use layers with dark themes.
c. Deleted apps with only a white background.
Replaced f.i. Gmail by Aquamail.
At this moment I use the lite stock rom MOB30m of Danvdh. Prerooted and debloated.
I suggest to start with flashing this ROM.

I signed up for the Android N beta and updated, that seems to have fixed the draining problem but not the battery dying at 50% . Any ideas how to fix that? Or do I need a new battery?

Sounds like a calibration issue. Google that and try and see if that helps.

P) high battery drain

hello everyone, here is my problem - in last couple of week i'm having really big battery problems (to the point i'm thinking of smashing my phone to the ground ) I take my P9 of the charger and it says it is at 100%, after only few min it drops to about 90%, and when i open some app (facebook atc) it freezes and when i try to turn it on again it says 0% battery!! when i hook it up on charger it takes 20 mins to charge to 1%, and when i turn it on again it says anywhere between 40% and 100%!!! Freezing most commonly appears when i turn on my camera and take a picture, it snaps then freezes. Tried with the factory reset it didn't help.
Please anybody!!!
Most likely the battery has worn out. Is it still under warranty?
Same here, sometimes camera apps freeze and then i will reboot it. After reboot, phone shows 5% power and then force itself into shutdown. The battery actually may not empty as told by phone, when i start charging, it shows more than 5% and phone actually have juice to run longer.

Sounds like a battery replacement to me. Have to tried installing AccuBattery or anything similar to check the battery health?

It's not the battery causing this fault

I have replaced the battery in my P9 and it still gets a power drain when the camera is operated. This usually occurs in low light environments. If I immediately turn the phone back on it starts up with maybe 20% battery, which then drops 1% a second and gets hot. This is with a brand new battery fitted. I conclude there is a glitch with updated software. Hopefully Huawei will read these posts and correct with future updates.

Not the battery
Try removing your sd memory card. I think a malfunctioning sd card was causing issue of battery drain during camera use. I can't explain the full science behind this, but my p9 phone has been fine since I removed the sd

Random turning off of OnePlus 3T

Hi guys, I have the following problem. My phone keeps turning off at random times. Today it happened more then 5 times. The problem started about a month ago. The phone started turning off at random times. So I did a factory reset with complete data wipe and it didn't help. So then I disabled Google services like Chrome, Disk, Gmail etc., Cleaned the chache as well. So this stopped the problem for a while. The I decided to turn back the services one by one to see if it works and it did work alright for a week or so. But since yesterday the problem got worse. I disabled the services one again but the problem stays. I should point out that about 6 months ago I send the phone for a battery change and it was done in official OnePlus service center with OEM part. So the battery should be fine. What I noticed is a huge battery drain on the phone while is turnes off. I attach screens showing the drain and that it had about 1,5 hours of screen on time. There is barely any app on the phone. I use Edge instead of Chrome, I have Viber plus three or four other apps to try keep it simple. Can you help me with that issue?

Just wow. I have exactly the same problem. I also changed the battery 6 months ago like you did but myself with eBay battery. I was thinking it has something to do with the battery cable not connecting properly but the battery was changed 6 months ago and the problem started 1 month ago like yours. The eBay seller is sending me a free replacement to see if it works. I also tried formating ,wiping cache etc but nothing worked. I have no issues with battery drain at all though. The new battery works fine. Sometimes I notice a little overheat that I have never seen before in the 3 years I use as a daily driver. Also sometimes when it powers off, the only way to power it on is by plugging the charger.

Catastrophic Failure?

I've had my SM-T810 (Tab S2 9.7, wifi) for four or five years now. A year ago, half of the screen began flashing brightly if I tried to use it on low brightness. To solve this, I turned up the brightness a bit and used the app Darker.
Over the last few weeks, things got much much worse. The tablet required more and more brightness to avoid flashing, it would stutter when playing videos, and responsiveness was slow. Every so often it would lose WiFi connection when my other devices didn't have trouble connecting.
Today, there has been some type of catastrophic failure. I was watching a video, when suddenly the video stuttered, froze, and the tablet became completely unresponsive. None of the buttons worked at all. It would not turn off. After about 15 minutes, the screen began its old flashing routine...and then something new happened: the flickering was joined by colorful lines, and about five minutes later the tablet shut itself off. It had become quite warm around the volume rocker/card slot area.I can't turn it back on, but if I plug it in, it shows the battery percentage. The tablet has never gotten wet, and it hasn't been dropped recently. Any thoughts? Thanks in advance!

Is the battery indicator dimmer than normal? Normally I would just assume at least the screen is bad, but since the charging indicator seems to work? Perhaps you should try download mode? Odin over fresh firmware? (You will lose data on the tablet though)
No, the battery indicator doesn't seem dim. I'll have to try your suggestions. I'm starting to think the motherboard is bad, and that would help me determine if it is or not.

Maybe some files in EMMC corrupted? Then if ODIN works it might get it back to life.
