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;

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.
I hope I am in the right forum for this...
Lately my two year old tf700t won't stay on for more than 10 mins at a time. I have the dock and both parts say more than 100% charged.
Due to my device being out of warranty and thinking something was wrong with my stock asus rom. I downgraded the rom, rooted it, unlocked and tried several different roms.
My tablet is still turning off even though it says it is 100% charged.
Is my problem a bad battery? I think it has discharged "fully" (to where it warns me) maybe 10 times in the two years i've had it in the dock. It has almost always been plugged in or lightly used around the house. It has never been drained and recharged repeatedly to the point that I would have thought it to be worn out by now.
When I've had batteries go previously, they just drain fast from 100% to 0%. Both batteries are at 100% and it won't stay on but maybe 10 minutes unplugged. When I plug it in, it takes about 5-10 mins before it turns back on again. Meanwhile, the led by the power button blinks orange like the battery is dead. When it turns back on, it tells me I'm fully charged. grr
Does anyone know what is going on? Is there a way to test the battery or is there some chip inside the thing that needs to be reset or something.

It sounds like that you have a calibrations issue with your device. When your device is shut off by itself, you should leave it unplug about a day. Then recharge your device after a day of depletion and hope that it will solve your problem, good luck...:fingers-crossed:
Mhhhh - "almost always plugged in"?
Not the best use for these batteries. 2 years of that could have killed it.... And then - may not have anything to do with it if the battery went bad. 2 years is not an unreasonable life expectancy for a battery for a portable device.
In addition to LMK's suggestion, you could try this:
Let it die and then sit for a day unplugged.
Connect it via USB to your PC and let it trickle charge for 8+ hours (charging indicator will not even come on). Make sure your PC doesn't shut down or go into sleep mode during that time.
It should be charged enough to boot it. Check if it made a difference.
So, I have a Verizon Samsung Galaxy S 3 that I got around the time they first came out. It's never gotten wet or really had any problems until the past few months. The first thing that happened was the power button broke and it was stuck down for quite a while before I figured out how to "fix" that. A little carefully applied WD-40 around the power button did the trick. I got a new battery and everything seemed fine.
Lately, however, the charging is not working correctly at all. I'm using the same charger that came with the phone and it will seem to work fine most of the time, but it has problems once unplugged. For example, I'll charge it overnight and wake up to it being at 50-80% battery. Other times, I'll charge it overnight, it will then show 100%, but after unplugging it, it will very quickly, like a few minutes, drop to the ~85%. What happened today though was the final straw. I turned it off and let it charge for about 4 hours until it said it was full. I then took the battery out for 5 minutes before putting it back in and plugging it in again. It then said it was at ~15% battery. I turned it on and, yes, 13% after ~4 hours of charging. I still occasionally have problems with the power button getting stuck and causing a rapid discharge, but I can fix that now and I carry two batteries usually. Not being to charge them though isn't going to work.
I currently live in Taiwan and use Chunghwa Telecom. I constantly have a little notification that says "This SIM card is from an unknown source", but I didn't have problems until months after moving here.
Any thoughts on what could be causing the charging to malfunction and how to fix it? I love my phone and would hate to part with it.
Recently had to replace battery.
Phone was shutting almost immediately after it was disconnected from charger. Charging status when not switched on showed the battery kinda going in reverse. Phone was really odd as it would suggest the battery had 100% charge and then within minutes of disconnecting it was shutting down.
I tried a factory reset/refresh with no change. So I ordered a Genuine replacement battery off flea bay and installed that last Thursday.
Initially phone seemed ok, then wen a bit weird and shut down even though charge was like at 70% or so. Wouldn't restart until plugged in and then in shutdown mode the battery/charging indicator would show 0% and then very quickly showed 70%. Good bit though was it was going up and not down like before.
Fully charged phone overnight. It then seemed really good and lasted until Tuesday with 66% charge still showing. I had not installed FB or Twitter which made a huge difference. Then yesterday it just shutdown again. When plugged in showed 0%, within minutes back to 70% and then charged to 100% in the space of an hour or so.
So I am looking for any advice. Is this just calibration issues that the phone needs to get past. Is it possible the phone has corruption int he ROM.
I appreciate it might be a hardware fault but seems weird that the replacement battery is clearly showing a big improvement suggesting battery was EOL after 2 years use.
TIA

Same problem here i will try to install the oficial rom of xt890 if works i back here if not i don't know what to do
Sooo............issue is still present. Odd thing which I am unable to confirm, due to rnadomness of shutdowns, it that I think it is slowly learning the state of the battery as it originally was shutting down at 70% after 2-3 days on standby. then 66% hen 56%. I did a clear cache partition and a fresh install but still the issue was present.
Clearly the new battery is lasting longer than the old one, just the phone does not seem to know to reduce the charge indicator all the way to 0%.
Anyone any idea why this might be happening.
TIA

Just to add i'm having the same problem.
Symptoms started last week running the stock kitkat rom so i ordered and a fitted a new battery. Initially everything looked good phone said 100% left it over night and noticed it had shut off when i came back to it. Plugged it in to the charger and it said 0% so i charged back to 100%, booted up android and almost immediately it begins discharging rapidly, i would say within 15 minutes its back down to 0%.. I've done this a few times now even left it on charge overnight for 8 hours but its still discharging rapidly everytime. The craziest thing is even if it says 0% in android i can still boot in to recovery and flash away so clearly there is charge in the battery its just android thats out of sync.
What i've tried so far:
Different wall chargers/USB leads/Outlets
Wiped everything in TWRP and flashed CM11
Factory Reset several times
Various battery calibration apps
My next step is going to be trying RSD to flash the stock ROM but beyond that i dont know what to do.
I'm experiencing EXACTLY THE SAME ISSUE with my Razr i, replaced the battery and it's still discharging very fast
Eventually managed to resolve my new battery issue simply by fully charging and discharging several times. It started to hold charge after the 7th charge and after several more discharges it's now up to full capacity.
Hi all.
I've had my gear for about 2 years now.
One day, about a month ago I forgot to put it in the charger and the battery drained totally. After this small incident I can't get the watch to start anymore.
I'ts completely dead, does not respond when I try pressing/holding buttons, charging it or whatever. The charger starts blinking red after a short while.
I also tried to solder a USB cable to the connections on the motherboard but no reaction with that either..
I've tried to replace the battery the other day and success, it started!! But, only for an hour or so, now it's dead again, exactly like before.
The battery that sits in the watch right now is almost fully charged and measures 3.7 volts directly on the contact surfaces.
Anyone got an idea what to try next?
Note that it's completely dead and does NOT respond to any pressing of the buttons or charging it in any way.
Regards
Emil
If correct soldered wires...
Then charging via USB possible...
Try maybe for 30 minutes to charge via USB...
Check if device will be hot
Maybe Hardware damage...
You could check Service Manuals... Schematics:

Lithium battery fully charged are at "4.20V". "3.7V" is the nominal voltage (mean stay at 3.7V 80% of the time during discharge time).
Samsung Gear S3 Battery Issue Fix
Samsung S3 Frontier Learning Mode found for charging issue SM-R760. The solution (keep in the charger while doing resets) is to reset the watch 8 to 10 times and keep holding the power button and shutting it off about another 10 times. This is unusual however my battery went from 1%, 4%, 16% and the flashing red light stopped and went to 100% charge in 2 1/2 hrs. I will keep the forum informed any changes if this reoccurs. I definitely think the latest update blew-up the cache in watch and somehow takes multiple resets and power button presses to reset the functionality of Samsungs mistakes.

I changed the battery because it was no longer charging. Recharged and gave 100% charge but now the power button does not turn on. He charges but does not care. Any suggestion?
Thank you.

It is supposed to have 100% battery but in about two minutes it drops to 90% and turns off.
