Hey guys, i've seen some other threads about batteries being stuck at 100% but they were generally with rooted devices so i figured i'd make one here.
The Problem
My infinity will charge fine, usually 1% per minute and when discharging going from 100% to 35% in about 5 hours screen on time, mainly using web apps, no real gaming, maybe dead trigger for 20 mins per charge. However when i take my tab off the charger it will stay at 100% for over 45 mins, and most recently over 1h 20m, causing the battery reading to be way off. Today it randomly shut down claiming i had 20% left.
Does anyone have any ideas? Like i said device is non-rooted and i dont have much interest in rooting it. Problem started just before we got the Jelly Bean update, and i got the tab in mid august, so it was working fine for a couple months.
The next logical step would be to factory reset and contact asus if that doesn't solve anything. I was hoping to avoid that if you guys had any tips or tricks.
Thanks
My TF700T has just started doing this. So your not the only one. I've only just started to search around for a solution.

I suggest you make a backup then do a a factory reset (twice). After that check to make sure this issue is gone, before re install any apps. If this doesn't resolved the issue, you need to reflash the full Asus firmware. This eliminated your software issue, and the last 1% chance is your hardware.(but very rare).

I've done as you suggested. Including factory reseting the tablet twice.
I've had the tablet off the charger for 14 hours and 28 minutes. And it's still showing 100%...
Worth noting: It was fully charged with the dock this morning. I've taken the tablet off the dock and used it for the day and it's still 100%
Anyone else got any other suggestions?
Same problem here, started two days ago, the transformer shuts down at ˜33-35%. Installed battery monitor app and it reports ˜500mAh still availble just prior to the shutting down. After it shuts down it's dead until I plugg it the power chord, it charges to 100% but then the same story again, shutting down at 33-35% remaining battery left. I've tried the battery calibration app which deletes the batterystats.bin file but that didn't do anything. Also tried three factory resets without any success... I'm on stock ROM but rooted.
Any ideas to what to try now? Or should I wait for the next firmware upgrade and see if the reflashing of the firmware will resolve this?
How do I reflash the installed firmware version, want to try that next...

What do your power saver settings show under settings?
Mine are at 10%
Have you factory reset your tablet recently?

Everything in power saver settings is left default, 15%. But the transformer never reaches that level..
Oh, and I also have the same behaivor as the orginator of this thread, the battery shows 100% for good while after a full charge until it stops dropping, forgot to mention that. My tablet is four month old and this just started... Unfortunaltey is feels like a HW issue with the battery reporting the wrong remaining charge to the OS... But I will wait for a new firmware to see if a reflash resets the battery configuration somehow.

My TF700 shut down at 25% battery today. I think it's time to contact ASUS to see what they can do.

Try to poweroff your device and let it stay down for 1/2 hrs, then power it back on see if that resolved your issue.
You need to recalibrate the battery.

I tried this to no avail. Worth noting the device was off for about 5 hours when the battery went flat. I've also tried turning it off and charging it.
I have a TF700 on a TF300 dock, and I have found that if I unplug the tablet from the dock, while the dock is plugged into the wall, it stays at that battery level until I plug it back into the keyboard. Deleting batterystats.bin, turning it off, waiting long enough for it to get to 8.4V, and then doing a cold boot seems to fix it.

Hi,
I loaded my TR101 yesterday to 99 or 100% ( tablet, undocked), disconnected it from the adapter, used it for some time, and then shut it off. The battery level was around 75% then.
This morning I started it again and the battery level was 98%! So it tells me it loaded in the night from 75 to 98% from thin air. No adapter connected. The dual battery widget shows this too: battery level went up from around 75 to 98.
Is thre any explanation for this? I suppose the battery level is not really 98, but what happened? I conbected the adapter, and the it starts loading to 100%.
I am no twaeker, so I did nothing unusual. I installed all the system updates Asus gave me. Now I have Android 4.0.1.
Any thoughts?

If you docked it again once you shut it off then the dock would have charged it

Yes, I know that the dock charges the tablet battery, but the tablet has not been docked for two days!
BTW: When I started the tablet (undocked) up again after two hours, the battery once more said that it was charged for 98%.
I then used it until the battery said it was charged for 31%. I wonder how the situation will be tomorrow.
First, wipe battery stats if you can. Second, empty it out completely (be careful about the 0% bug) then do a full charge.
Recommended battery use is always to empty it out completely then charge it completely. It'll extend its performance and lifetime.
How do I wipe my battery stats? I cannot find any control to do so. My tablet is not rooted btw.
Anyway: This morning when I started it up the battery icon was red and it shut down by itself (empty battery?), but when I started it up then with the adaptor the battery stood at 17%. This might have been the real status after several wrong indications yesterday, I suppose. Battery health is displayed as "good".
It only seems a matter of wrong indication. The battery last the normal time, it seems to me.
I will let it go to down now util just a few % and fully load it again then.
The reason why I normally shut the tablet completely down when I do not plan to use it for several hours, is that the battery drains when the tablet is 'sleeping', but when I shut it down completely it later starts up at the same level when I shut it down.
This sees to be an issue Asus had to solve (you could read about it all over the internet when I fist noticed it) but as usual Asus is only intrested in upgrading its latest models and soon abandons active support for what they consider "older" models.
However, I do not buy a new tablet every few months. I consider a tablet old after maybe 3 years or longer.
To continue the battery issue: Also, when I shut the tablet down when docked both battery levels have changed when I start it again. To avoid these battery annoyances I often shut it down.

Well the battery stats part is debatable really, but you need root as far as I know, so you can ignore that part.
About the battery draining while sleeping, I've heard other people having that issue. Not sure if it was ever solved... I haven't had that issue.
Last case scenario would be to make sure it's not a software issue by doing a full factory reset with something like Easyflasher. Corrupted files happens, and there's no easy way to "fix" it. Make sure you backup all important data as easyflasher will completely wipe your device clean, but it's the best way to confirm it's a software-related issue.
Hi,
A cold reboot did it!
For those of you that are as afraid of a factory reset as I am: a cold reboot does not wipe any of your data. You press the 'on/off' button together with 'volume down' button for about 10 seconds. You will see some small print and some unfamiliar pics on your screen. Ignore everything, because a cold reboot is the default thing that will happen.
When your Transformer has booted after this, several things have changed for the better, including your battery indication.
If this instruction is not clear enough, google for 'cold reboot Transformer'.
For me it worked and I found it to be fool-proof.

I have a locked & unrooted WW TF700 & genuine dock on JB 4.2.1.
A week ago I started to notice an issue where the tab would constantly drain whilst it should have been asleep. Overnight it would loose ~30% instead of ~2%. I tried a few settings, but couldn't seem to solve it. I decided to do a factory reset because I haven't done one since I last upgraded to jelly bean. That appears to have cured that problem, but has created two more.
The first problem is that I can't seem to charge the tab over 81% when being charged directly. If I then plug it into a fully charged dock it will charge to 90% but no more, even with the charging cable in the dock.
The second problem is that the tab now decides to shut off at about 30% battery left. It won't shutdown as normal, just go blank and won't boot up again without being charged a little first. I have read threads about artificially overcharging the tab, but a symptom of that is the battery level will remain at 100% for hours before starting to drain normally. My tab won't charge to 100% and will start to drain immediately after removing the charging cable. Regardless I have tried to drain and recharge overnight with the tab both off and on but the tab won't charge past 76% overnight in either case. Restarting multiple times doesn't help at all.
For the first issue I started to suspect the charger may be at fault. This is because if I charge the tab directly, it will never get past 81%. However, if I then plug it into the freshly charged dock it will charge upto 90%. I understand that the dock will never charge the tab past 90%, unless it is plugged into the charger. Does it assume in my case that it isn't plugged in to a charger even when it is? I should mention I am using the original asus charger. Frustratingly I can't just use my phone charger to see if it solves the problem due to the 15v of the asus charger. I have noticed a slight hum/buzz coming from the charger but I can't be sure that it didn't do that before. I have had issues with the internal connections not be pushed together quite right before and getting no charge out of it, but 'clicking it together' a bit more firmly did the trick there.
Even with an overnight charge, plugged into the dock to get it to 90% I now get terrible battery life. Roughly 30mins per 10% juice. Previously I was getting around an hour per 10%.
Does anyone have an suggestions for me on how to eliminate the charger as a problem, or say doing another factory reset on a 'full charge'? The only other thing I can think of is to let it drain, give it enough charger to turn back on, then turn it off and leave it unplugged overnight (I saw it mentioned in another thread). I really appreciate any help you can give before I have to try the dreaded warranty route!
Try this with it undocked. Let the battery discharge to zero, and leave it 24 hours.
Then recharge it fully. This seems to cure the battery calibration memory issues.most us know how you get on.
Luckily I have located an Asus charger to borrow and hopefully find out if it is just my charger or not.
I also tried out CPU-Z and the battery is reporting as only having 7mV. I'm sure that can't be correct as my HOX+ is around 3500mV, and 7mV just couldn't power anything. I don't know if this is just CPU-Z issue with reporting correctly, or a clue that there is something not right with my battery? Has anyone else tried CPU-Z or know what the mV should be roughly, fully charged say?
Unfortunately a different charger didn't solve my issue :'(
I've posted a screenshot to show what is happening. I'll try draining the battery flat and leaving 24 hours to see what happens then. Luckily I still have two months left on warranty.
Pretty annoying because everything else the tablet does is fantastic. I replaced my laptop with it and use it daily for everything.

Unfortunately things have become worse. I tried using the tab until it died (at around 50% battery this time...) and left for 24 hours as suggested. Unfortunately now I can't get the tab to turn on or take a charge at all. I have tried holding power button down, with vol up/down, for over a minute etc. Tried the reset button all numerous times with no luck. All I get is the LED blink twice when pressing the power button and this only happens when the charger is connected, otherwise nothing.
I have the phone number for Asus support and will be giving them a call tomorrow. I'm so glad I never unlocked my device!

Leave it for 24 hours not on charge first then try again. We've seen this happen so many times - the fix is to let it discharge completely.

Thanks Sbdags, I appreciate your response. I've read numerous threads tonight with similar issues. I did try leaving the tab for 24 hours completely dead overnight last night. I'll try it again (I don't know if the battery is dead or not currently) but I'll leave it unplugged as there is nothing else for me to do with it anyway!
OK, I thought I would complete this thread.
After leaving my tablet for a few more days not on charge I could seem to get no life out of it whatsoever so went down the RMA route and the result of that is in the following thread;

All of a sudden my phone started to turn off when it read that there was still battery life left on device. But it will not boot up until I plug it into a charger. Once I do, there are times it reads 100% charge, random %, or completely dead. Since the first time there hasn't been a time it has properly drain the battery with a proper shut down. I have done numerous factory resets and complete wipe/fresh ROM flash. Currently I am on CM snapshot M6. If anyone could please me that would be great. It is starting to become pain in my side.
Thanks.

i hope you remember if you solved it
I have been using Nexus 5 for a year and half now. After upgrading to android 6.0.1 recently, I have been facing serious battery issues, such as:
1. Sudden shut down of the device, from various % of battery remaining. After trying to switch back on, the battery shows empty, or even 5-10% charge remaining.
2. If I charge it fully and then switch to safe mode, the phone works fine, the discharge rate is pretty stable and long-lasting. If I then try to switch back to normal mode from safe mode with a simple restart, the battery percentage again shows drastic change in between the two modes.
3. Sometimes when I keep it in safe mode, the battery percentage shows an increase, even if it's not charging.
* Yesterday I did a factory reset, yet these problems continue. I am confused about this being a battery problem, android bug or something else entirely.
I am a newbie in this forum, so please pardon me if I am missing some things here. Any help would be much appreciated. Thanks

Yesterday evening I charged my N5 to 100%, used it 5-10 minutes while in bed and turned it off; this morning I turned it on, used it for other 5 mins (the charge was 86%) and it shut down on its own: when I tried to switch it back on it appeared to be completely discharged.
This happened several times in the last weeks, alongside a way faster discharge of the battery.
Is there a way to check if this is related to some software or it a physical problem of the battery? And, in case, is it possible to change it?
Flash back to stock LP to see if the problem goes away. If the problem continues, it could be time for a new battery.
I've not been playing with roms and stuff for a while and I don't remember that, if I flash stock LP (I'm on stock Marshmallow now, if that matters) will I have everything on my phone wiped?

You could try flashing everything except the userdata.img file. After flashing the other partitions, erase cache before booting the LP ROM for the first time.
I always recommend taking a back up of your data before flashing anything to the phone as there is always the possibility that something goes wrong.

I tried to install an app to calibrate the battery but I'd need to root my phone to make it work (as now it's not rooted), and if I remember correctly the root process would wipe my phone (and as right now I don't have much time for that I'd rather try first everything I can without wiping).

Alright, though I'm afraid it might come down to that..
But lemme know anyway if you managed to fix your battery issue without having to calibrate the battery. I had a similar problem but it hasn't gone away yet even after calibrations. Maybe a new battery is in order.

No... It will be ok after the phone has run out of battery and charging it again will restore the state of battery. But it will not get full if you use it rapidly while charging, then you have to use the phone again until the batteries level reach 1-3 % so that it restore the battery state.

Hi. Use your phone until the battery drained to 0% and switched off automatically. now let it breath for few minutes and after few minutes, charge it while it is in switched off, leave it for 3 hours let it charge until full, and don't switch it on in the middle, see if it is successfully charging completely within three and half hours. Hope this helps. Jai Hind!
Try disconnecting charger, turn off phone, then connect charger again and let it get to 100% before turning phone on again.

If you don't mind voiding your warranty you can open your phone, disconnect the battery and reconnect it. That's what I did when I had the same problem, but I would advise you to look up instructions on opening the Nokia 3 if you're going to do that. Otherwise you might have to go to Nokia support

It still reads 70% but gradually comes up to 74% finally but 100% yet. Any other options I can try please?
I just discovered something. It's whenever my phone enters recovery that the battery reading gets messed up so this is what I'm going to do: next time my battery falls down to say 3% I will boot to recovery and let the phone run down from there. Maybe when I start charging again the problem will be resolved
Update:
It worked. I let my phone run down till it shut down on its own then I booted into recovery. Interestingly twrp kept showing the battery as 50% even though I'm sure the battery percentage was much lowere. I'm guessing the twrp is not reading the battery well or even at all. Anyway I waited for a while before powering off the phone then charging. My phone finally reached 100%
When should we release the buttons in recovery mode ?
It worked
Guys, I followed the thread and it worked for me. I have been experiencing the same issue.
To fix it did the following:
Let the phone run out of energy
Wait some 10 minutes
Connect the phone to power and run the wipe caché instructions
Let the phone charge completely till 100%
I experienced the problem of not reaching 100% on energy (just 80%) for 2 days. Then I found the post. Fixed it.
Thank you!
