[Q] Battery Stuck at 100% for an hour, shuts off at 20%

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.

This is what I did. except I left it plugged in over night, then unplugged it, turned it on and it is back to normal.

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.

[Q] Xolo Q700(mediatek 6589)---Battery drop from 97% to 1% !!!!!!!

NO kidding.
97% to 1%. That is what happened to my battery level after I rebooted my phone. This is my replaced phone that i got from service center and the previous one was also suffering from this condition.
What the hell is wrong.
I have tried this:
Drained battery till it turned off and recharged to 100%.
deleted battery stats.
used an called Battery for calibration.
Note: I have read almost every thread regarding this problem and i am posting this thread thinking that this might be related to this specific phone because nothing else works.
SO anyone?

Your Battery is gone, Use Nokia BL5C with empty spaces filled with thick cardboards so that battery doesnt shifts position. It'll give you half of the original battery life though its only 1020mAH, while batteries available in market are waste of money, they wont even give you fourth of the talktime original one gave.

galaxy j7 battery problem

i think my phone has some serious problems and i'm wondering if it's the battery dying or a short circuit
when i plug it on a charger while of it shows a normal charging image but how it switches from one animation to the other so i can see the status of battery percent it's like a short on the screen happened
it chargers to 100 but when i switch it on it shows mybe 95 but never 100 and if i connect it to a charger to get to 100 it only decreases
it gets warm now days which did not happen and it like drains 50% overnight which is obviously not normal. these two days the battery life is like 4 hours with internet wich with j7's battery it should not happen. if i switch it off and then on again i loose like 20% of battery and if that is all i had i get 0% and the phone doesnt switch on. the phone never had contact with water . it's been 4 days since this started and it happened all of sudden like today my phone stays up to two days at most and i just woke up it barely finishes a day without data and with power saving mode
i'm sure it's not about background apps or any activities because i hard reset it already and i don't have any app. and it's not about wifi or sync or poor network i tried all that. i did everything it didnt help. i could buy a new battery but i'm scared it might be a short because i don't think a battery can just die in one night like this.
can anyone help me with this or it's nothing serious and i have to change the battery

Hold down power and vol-up buttons until you enter Recovery.
Format cache partition.
Reboot.

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.

Thanks.. its 100% effective!!

I did the recovery mode and formatted the cache partition. there was a significant increase from 63% to 70%. It's still not charging up to 100%. Should I continue to perform recovery mode or is there any other alternative? Please anyone, I need your assistance.

You might need to let your battery run down totally to the point that the phone goes off before charging again
I found out that it actually charges to 100%, it just reads wrongly

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!

Hi sir why my Nokia 3 is not charging from 82% to 100% thank you.

Charging Problem

It has been just 20 days, and I have just realised that there is a charging problem with my Honor View 10.
At night, when I turn off my phone and put on charge, the phone starts charging but in the morning i. e arnd after 7 hours I see that the battery is around 70% and still its shows that its charging but actually the battery is draining because after sometime when I check it again the battery is like 68% or so and it still shows charging P. S in whole process the phone is switched off and this happens every time (around 6 to 7 times). And I am using the same charger that came with the phone. Phone is updated to the latest firmware.
I have done the factory reset but still the same problem persists.
Please you guys check and let me know if anyone else is also suffering with same issue.

Better you should visit company service center or probably honor official forum for support from company... As far as I think it is your handset problem either check with ampere app from play store to see how much current it is taken when charging , so either your charging port is damaged , maybe charging IC or maybe battery issue... Not sure though..

Apr 2018.. Same charging issue. Shows fast charging but doesn't
This post is from Feb and I bought this phone now in Apr. I am facing the same issue. The fast charging lasted for a day and then it is very slow.. Max 750mah measured via Ampere app. Earlier it used to be excess of 2500mah when it was fast charging.
Have you find any solution to this issue?
