My phone has started to do odd things regarding battery charge level. Have tried full-charge-delete-batterystats more than once, tried restoring older version through CWM and that doesn't seem to fix it.
This pic shows the behaviour quite well:

The phone was shut down (with fast boot enabled) over night, and appeared to be off, but it was draining the battery quite fast and reports that the display was on, despite this not seeming to be the case.
Disabling fast boot cures this, but it never used to be a problem - I've used fast boot for months without this happening. And I quite like the fast power up.
I think put the phone on to charge, and it often seems to charge really slowly. I did a full reboot and left the house. Rebooting caused the charge level to jump up, and then it discharged as I used it quite heavily, before putting it on to charge when I got to work. Other times, when I do a reboot it'll drop 30-40% in charge immediately!
the phone is about 16 months old and maybe the battery is just worn out ... or is there anything else i can try which might fix it?

Hi,
WIPING BATTERY STATS, IS A MYTH
Looks like it might be worth trying a new battery.
That spike in battery % left when you rebooted looks like the standard Sensation battery goofiness... I replaced my battery at about the same age that yours was and its performance had definitely degraded quite badly. It would discharge much faster than when new and charging took longer as well. Replaced it with an Anker 1900 and it's better than ever. Lasts all day and charging is nice and fast.

So my TF101 appears to be completely dead. I had it rooted and rom'd running KatKiss 4.3,not sure of which number . I loved it too. Anyway, before it died, it rebooted and would not leave the "updating apps"screen so I did a factory install which fixed the problem but only temporarily. A few days later the same thing happened. This time I could not even reboot it. I left it charged overnight but could not get it to boot at all. I think I have tried everything. I tried booting with and without being on the keyboard dock, I have tried plugging into the computer, tried hdmi to a monitor to see if the screen went bad. I tried seeing if the computer recognized it in APX mode. NOTHING. The USB charges the keyboard dock but does nothing for the tablet. The computer does not see it period. It looks completely dead. It is out of warranty but I even called ASUS and all they would do is charge me $340 to send it in.
I would love to troubleshoot to see if it is a board or battery or whatever gone bad , but I cannot find anything on the Web. Can anyone help. Otherwise it's a lovely paperweight.
It's possible that the battery has come to the end of it's life and won't hold any charge, which would explain why APX mode won't work, the PC can't power on the TF via USB, only trickle charge it while it's powered off / screen is off, but if the battery is dead then that's not gonna happen either
Not sure if the charger needs the battery for it to power on the TF too or not
You could try disconnecting the battery and plugging in the charger
Here is a good teardown video to show exactly how to get that done

Im not 100% sure, but if the dock battery is fine, you could check and see if the connections are the same and swap them over

Still DEAD
Detection,
Thanks for the awesome YouTube of breaking down the TF101. Unfortunately, I swapped batteries and still no good. Nothing happens. It looks like the old battery has power too, based on my multimeter. Is there anyone else with suggestions at this point or do I leave it as a nice paperweight?
THansk....
Apologies for resurrecting this thread. My TF101 (with dock) had also gone dead after running one of the KatKiss ROMs (maybe 4.2). Wouldn't charge, wouldn't turn on even to the bootloader or recovery. Charged it for days, nothing. I left it for dead and forgot about it for over 6 months. Uncovered it the other, dusted it off, charged it and it magically powered up. Everything was still on the tablet as it was before it went unresponsive.
My guess is that a microcontroller responsible for powering up the tablet got into a bad state. Even when powered off, these very low power microcontrollers remain on to handle the button press that powers on the device. It took the tablet being absolutely, fully discharged to clear it out of that bad state. Not just 0% as reported by the battery firmware, but a true complete emptying of the battery where its voltage drops below what the microcontroller needs to remain running.
Hopefully if you still have the TF101 after all this time, try charging it up all the way and see if it comes back to life.
I'm experiencing some weird battery issues on my Samsung B5330 (Galaxy Chat). Since there is no GC forum and it's probably a software issue I'll wirte here.
The phone is full stock, no root nor any modifications were made, 4.1.2.
At the beginning of my adventure with this phone I experienced a problem with Media process eating the battery. That was probably caused by one of videos, faulty mp3 file or Gallery system application. Once or twice a day 46% of battery was eaten as shown in battery stats. However from time to time the phone just died and battery stats had just a blank space from the last reading The phone got hot because of CPU usage. As it also happened at night and affected an alarm clock and had to be dealt with.
I turned off Gallery, Media and Media history services (in App properities) and replaced them with independent applications. First problem was solved and the second one become clearly visible.
It looks like this:

There is nothing indicating extensive battery use:
The battery reading goes from 80% to 0% in 80 seconds and the phone dies. Nothing overheats, nothing hangs. After 1 - 2 days if 60% is shown and I restart it, it goes to 0% instantly.
It's either faulty battery or software bug :/
Any ideas what can I do with it apart from buying a new battery?
battery problem
This looks like a hardware problem (with the battery), my apenion is that it coudn't be a problem with some faulthy mp3, music or video player or so, it could be a problem with your background working apps / make sure you clear all of them and make sure you turn off all wify, 3g, edge and so in your phone settings, and see how much time it works then.
The com.android.media process as a source of the first problem is confirmed, as it is widely described on the net and it was noted in battery stats.
The problem is what is shown on the photo. I'll just buy a new battery since it's not expansive. I thought it may be a software problem as it looked like the indicator was not properly calibrated or refreshed.
The longest the phone was alive after solving the Media problem was over 3 days with everything on. It went down to 20% and then died.
This also suggests the battery...
OK, problem solved. Good ole' wipe did the trick.
The problem was purely of software origin as voltage of charged battery was marked as 100% but voltage of an empty battery was marked as 50%. So it reached 50% and died. After the wipe it goes down normally to 0%.
Hi all,
Recently my brand-new Be Touch was suddenly bricked, I don't know why but it was unresponsive to everything... they screen just didn't wanted to show anything even when I connected the charger or plugged it to my laptop.
I tried all the instructions I found (there are really a lot of just googling "recover bricked phone"), even the official instructions to flash a new ROM (http://ulefone.com/download/betouch.html) But again nothing... screen completely black.
I tested the battery with a multimeter and it appeared to be full charge.
Finally when I had already contacted the seller for a return, I found a very old post (2013) about recovering a bricked device using Ubuntu (I'm using Linux Mint).
So I had SP Flashing Tool open (not doing anything special because it didn't detect my phone any longer) and in the Options -> Connections -> "with battery" marked.

The USB cable was plugged and the battery on its place.
I pressed "Power + Home" buttons simultaneously for around 30 seconds. It's real, I had tried before for around 10 seconds and nothing happened... and arriving to the 30th second suddently the screen brighted once, showing for an instant a 0% battery and went down again... Hope was back
I left the cable plugged for some minutes before touching anything. When I pressed again (5min) the percentage was still at 0% but the screen response was faster. So I decided to boot the phone and it started
It was connected and still showing 0% battery. It started as on the 1st boot, asking me for everything, but everything working. I wait for around 10 minutes and... the battery was still showing 0% :-/ I decided to turn it down for a faster charge.
I left it around 45 minutes shut down to reach the 15% of battery (fast charge they said!) after that it started charging a little bit faster, I waited until 100% before turning it on.
Once at 100% it booted well, restored my config and everything seems to work well again.
Today I have installed a battery repair app (called Repair Battery Life free on PlayStore), and it has detected around 10 deffective units on the battery :-/ (someone in red) but after clicking on "Fix it" and wait for some minutes it everything appears OK now. So I will pay more attention to it working and the battery from now on.
I don't know if all that story was caused by the battery... but at least my Be Touch is back
I'm trynig to paste screenshots of battery recovery, but I can't :-/
PS: if you find this info useful, I would appreciate if you click on "Thanks"
Maybe this post should be on "Help & Troubleshooting" ?
Not sure...
My phone has been turning off at seemingly random times during usage. It started with the camera taking photos, then when the keyboard was about to be brought up, then right when the boot logo finished, now its when the white HTC boot screen starts. It seems to stop when i plug it in but after it take it off the charger its prone to turning off. I've gone the entire day without it because of this issue. Anyone else experience this / have a fix? Any advice is greatly appreciated at this point.
Its also worth noting i am on the latest FW and am running the marshmallow GPE rom, although i flashed a sense marshmallow rom and its was happening upon boot as well.
I'm still using lollipop on my m8, but my mother in law and I have had awful battery issues with ours. Sometimes it decides to die at 40% battery, seemingly while using barely any ram. The battery icon flashes red and turns off. Many times It won't register being plugged in with various chargers, including a brand new one. When it does, it will estimate several hours to charge, as much as 8!
As I type this, I'm stuck standing by a wall while it charges. It had 100% when I went to bed at 3am and was completely dead when I awoke at noon. (such a reliable alarm clock) I plugged it in and it went from 0 to 40%. Wtf. It estimates 3 hours and 6 minutes until full.
It may very well be a bad battery but it could be the sensor. Found this a while back on Android central, copied the relevant bit below. (http://forums.androidcentral.com/ve...ry-charger-reset-procedure-htc-one-m7-m8.html)
This is directly from HTC tech support. To recalibrate battery and HTC charger when battery rapidly or erratically discharges, this procedure clears all battery stats, coordinates and normalizes charging.
Turn off Fast Boot in settings. Power off phone.
Plug phone into HTC charger and charge for two minutes or more
While charging, hold down volume up+volume down+power button and continue holding
Phone will turn on and off repeatedly every 15 seconds or so while continuing to hold all three buttons
Keep this going for 2 minutes, then release buttons when phone is ON
Now, let phone charge fully normally (with phone either on or off--doesn't matter) and battery level reporting, charging and battery life should be normalized.

Also, I don't know about yours but mine will drain the battery while searching for WiFi. So I usually turn WiFi off outside of my home.
Check out my battery chart. Haha.

Even with 2900mAh battery my phone last a day for me. Suddenly one night my phone discharged from 80 to 2% overnight in airplane mode and I found that 10%/h discharge on Accubattery (screen off). I checked my previous record it was 5%/h.
My phone also get too warm for idle. I tried shutting down and turning it back on and found that power button not working tried to turn on while charging it worked (Thank GOD!). I also found that battery drain continues even after shutdown.
Tried bitdefender (no problem found), factory reset, still the problem continues. any suggestions?
Accubattery estimation: 85% (2500 mAh)

If the battery drain happens quickly even with the phone switched off, then I'd guess it needs a new battery.
Another idea I've read somewhere is to drain the battery until the phone shuts off. Then keep trying to switch on the phone until there's absolutely no sign of life anymore, it might take a half hour. Then plug in a charger and let it charge to 100% before switching on. Supposedly, the idea is to calibrate the battery percentage meter and get a more accurate reading of your battery capacity.

It sounds like a hardware or battery failure, but you could try reflashing the ROM. Reflashing costs nothing, and there is a chance it could help. If it was me, I'd be looking for a new phone if the reflash didn't help.
