My TF thinks the battery is empty

I am now under the assumption that my TF thinks the battery is dead even though there was a full charge in it before I shut it down yesterday. I have been having issues regarding turning it on and couldn't even get into APX mode. I have just tried APX again and manged to get connected, started to run NVflash, then the screen came on showing the large battery image with the red power amount tne just disconnected. I had the TF on charge all night to so there should be full battery.
Anyone else have this issue or know about a fix?
Thanks

Can you get to recovery? Have you tried reseting battery stats?
Also are you using stock charger or have you charged the tablet with another device?

Cheers for your reply m8. At this moment in time, I can't get into anything. Managed to get APX mode earlier, but like I say, it shut down thinking it had no battery, even though it should have been full. Yes it is stock charger and not I haven't used any other method of charging. I am unrooted and stock so other than using CWM, I don't know how to wipe battery stats. Will wiping Battery stats help? What does it wipe?
Thanks

Well I emailed ASUS this morning and have got an email back from them saying it needs to go for service. Just filled out the form for RMA, now just waiting for return details.
Gutted, not even 4 weeks old.

Wiping battery stats clears the data that the device has of the battery. Its like reseting or recalibrating it if the device's battery level isn't displayed as it should be.
EDIT: Seems you posted before I finished with this one... Since ASUS told you to service it, it might came like that from the start. Good thing you didn't root or install a custom ROM.

Thanks Azureus.
I looked at wiping the battery stats when I first rooted, but wasn't sure what it did so just left it.
Yeah it is a good job it aint rooted. Just wondering now on what the turn around will be. This thing has grown to be like my right hand, lol

Well looks like I am getting a replacement tommorrow all being well. Just got an email back from the place where I bought my TF from and they have 1 left in stock. Gonna leave the RMA ongoing until I have the new one in my hands.
Ooooh, can't wait.

[Q] Wiping Battery Stats?

Hi Guys.
Hooray! My TF finally turned on again this morning after 1 and a half days of not turning on.
Is there any way to clear/reset/wipe battery stats without being rooted. As in previous posts, my TF thinks the battery is dead when I restart it even though it is either full or nearly full. Thought I would try and wipe the battery stats to see if that helps. I don't want to root as I may have to send back to ASUS and if I can't turn it back on again, then I can't unroot.
I haven't been able to turn on for a day and a half, nor could I get into APX mode. I did however get the large depleted battery flash on screen when trying to start up yesterday.

Didn't you get a replaced one?
Battery Stats can be deleted from CWM, but I don't know if there's another way of doing it if you're not rooted. Also if you've got a new device, I will suggest you run it a couple of times to see if it works as intended or not before deleting the stats...

Hi Azureus.
Unfortunately I couldnt get a replacement as the box it came in was somehow thrown out with the christmas rubbish, so they wont take it back. They will only send it off to Asus for me. Im not sure now whether to root and then wipe stats, Just worried it wont come back on at all.

IIRC someone else posted something similar a while back.
Try a factory reset before you do anything else.

Do you reckon factory reset will help? The battery reads fine i android, its just when you try to power up it shows the depleted battery icon sometimes and then doesnt show anything other times, just doesnt start.

I can't say for certainty, I just remember that's what was posted. Trying to find that post but it's buried somewhere.
At the least it doesn't hurt to try a factory reset. If it still doesn't help than you can root after that.
I think your problem is related to the "deep sleep" trouble more than the battery stats itself.

Cheers Baseball.
I was reluctant to do a factory reset as this would require a restart and I really didnt want to wait a day and a half for the damn thing to start back up again. While I was at the shop today, I got them to check the charger, he in turn said it wasnt working and gave me a new one. Strange how my battery was telling me that I had 99%. Anyway, I bit the bullet and downgraded to .19 so I could root again and do the wipe battery stats. Low and behold, after my TF turned off to restart and do the install of the .19 software, it didnt turn back on. So I thought I would plug it in and then press the power button as this had become the norm. To my amazement, after plugging in and before I could press the power button, the TF fired up and continued to install the downgrade. Hooray!!!
I am now just pumping in the last 2% of battery needed then going to wipe cache, date, dalvik and battery, then hopefully, and I say this with fingers crossed, that that might be the end to my issues.

Batteries not charging.

Hi, so i say batteries because i already tried 3 different ones. My problem started in gingerbread when i could not charge pass 50~60%, won't even matter how much time i have it "charging", then i rooted and install the AT&T release of ICS 4.0.4, then some days later it started to won't charge pass 1% and sometimes lowers to 0% and if i disconnect turns off, and connected never charges. I have tried with different chargers also, i have tried every forum "solution", factory resetting, procedure and no luck. If i go into CWM and delete batterystats or to do anything, the phone doesn't turn off, that's weird also. I bought an external charger and charged the three batteries to full, and when i put it in the phone, android still says 1% or 0% and turns off if i disconnect.
So anybody who can help me with this, i would extremely grateful. Thanks

Hi, yes i have bbs installed and i dont see any weird wakelocks, right now is just audio, which i read is normal. Today i get a 4th new charger and cable OEM Samsung to try, but honestly i dont think it will help.
The thing that confuses me the most, is that i charged every battery I've tried in an external charger, so the battery IS actually full, but when i put it in the phone, android still says 1% or even 0%. :crying:

Charge the battery in another phone or device, if you can. That would be the only option.

To be honest it sounds like something you may have installed or run on your phone, you said it started only a few days after upgrading to ICS which I'm guessing is how long it took you to finish restoring everything from GB.
My advice is to do a complete reset to the phone using kies, let it run for a few days with the minimal stuff you need and then start adding few apps at a time and wait to see if everything runs ok.

He can't do anything to it, no battery life, it will get stuck at flash or reset (kies) and brick.
The charger doe not charge, so he can;t even do it with the usb plugged. If he had power there are lot's of thing to test, ODIN or flash.

I'm out of warranty time now.

He said he already used an external charger and it didn't help, unless all 3 of his batteries are trash it's an issue with the phone.
He also said as long as his phone stays connected it runs fine so using kies should work I guess.
If nothing works I'd say it's some type of hardware issue and that means he will have to pay for a repair or he will have to upgrade.

Just take it to a small shop that unlocks or fixes phones, something small but nice looking, with bunch of phones for sale. Not Bestbuy or something)
They would usually ship the phone to a factory for fixing, that means they ship it to Samsung facility where some dude does work on the side.
I had my main board replaced to OEM for $190 where Rogers doing same would have charged me $420.
Your problem should not cost much, but you can;t put price on how relived you would be once it's fixed)

Hi, just to make an update, i did uninstall some stuff with root uninstaller, now the battery charges!! BUT to about 15~17%, then starts to discharge itself even connected to a charger. :crying:

So I suggest to do what I said before, start from fresh and install slowly, something must have screwed with your rom.

Would you recommend to install the stock release of ICS 4.0.4 or a custom rom? if so which is the best ?Im considering using this http://forum.xda-developers.com/showthread.php?t=1763195. Thank you

OK, so i installed this custom rom http://forum.xda-developers.com/showthread.php?t=1763195, the battery charges to about 19%, then starts discharging itself being connected to the charger. This is driving me crazy, i have tried so may things and nothing, been a few weeks without using the phone normally. :crying:

First go fresh stock using kies to see if the issue still persists, if it does it's probably a hardware issue. If you know someone that has a device with a battery thats works fine and it fits your device ask him to try it out so you can be certain it's your device and not all of your batteries.

Ok, i did all that i could, reinstalling stock GB 2.3.5, same problem. So im pretty sure it is a hardware issue, or possibly the 3 batteries i have are trash. I will see some place in san antonio texas, that can fix it. Thanks for the help everyone. Sadly this stuff happens, but what can you do.
PS. If someone sees this and thinks that can fix my problem ill gladly discuss payment for your work. Pm me. Thanks.

Phone shutting down at random %ages (50, 60, 40+)

Hi All,
I'm facing a weird issue with my phone from more than 2 months and it has reached a frustrated level now. It used to shut off at levels like 15%, sometimes between 15-25%. But nowadays, it shuts down automatically at 40-60% and that is really unreliable. So, i wanted to check if there are other people facing the same issue or is it only my device. Please share your views, any possible solutions, possible reasons, and if applicable, similar experiences.

thanks for the info, i got my oneplus one back in 2013, hopefully it will not shutdown after a while. i have not found such problem and hope i will not in the future as i want to have the phone for at least 5 years

thanks so much, bought it after my nexus4 died which im still sad about because its one of my 1st real android phones after having a contract android phone.

As an update, i kept my phone on charge for straight 4-5 hours. and now it shuts down after 20-25%. Definitely an improvement. But still it's a mystery why does it show this bug in the first place.

Umm, how has no one mentioned maybe trying battery calibration!? Seems like a fairly obvious first step here to take before swapping out for a new battery.. Plug the phone in and let it charge entirely. Even at 100% in Settings > Battery it will still show "100% - Charging on AC" (or USB whatever you've got connected)
You need to wait for that to turn into "100% - Charged." Then, calibrate using any battery calibration app from the playstore, ( I use this one )
After it charges to 100% - Charged, hit "calibrate" in the app, disconnect the charger, and let it drain entirely. You might find it dying out before 0% once again, but this hopefully should have been the last time. Plug the phone in and switch it on as soon as you can while it starts to charge. Let it charge uninterruptedly to 100% - Charged, again.
Not saying this might solve it 100% but it is an option to try.

Well already tried and i may sound a bit silly, but studies have proved that battery calibration is a myth. Android automatically cleans the batterystats.bin file after every single full charge. Rest assured, i have already done that with no avail.

I had the same problem, phone was switching off @ 40% and at times @35%. Battery calibration certainly helped. No more problems now. Works well if the phone is rooted.

Battery losing power when phone is switched off!

Has anyone else experienced this?
I fully charged my phone in the evening, unplugged it and switched it off. About 10am I went to switch it on and found the phone to be warm to the touch. When I switched it on the battery was showing 60%.
This is one of a long line of battery issues.
What can I do to sort this?

Seems like your phone doesn't shut off at all :s
I would just turn it back to the store. Nothing you should have to do with it at all to get it working.. It's a new phone.

Unfortunately I bought it from Gearbest, and as such returning back to store is not an option.

Your best shot is try to factory reset then.
But if there is a hardware issue u just have to live with it.

Has anyone else had a hardware issue?

Does your battery life section show what's consuming the battery?

U sure it was off ?
Not just locked...

Have a look at these battery stats.
Seem weird to me.

This morning my phone turned it's self on just prior to a 6am alarm. Seems like when the phone is off, there are still some processes active.

I agree with @whizeguy here.

But I would go a step further than that. . . . I would "fastboot boot twrp.img" and then within twrp, do a "format data". . . . Backup your phone's download / music / pictures to your PC first ! ! !
.
Use this twrp with mtp working . . .

Then I would put the rom back on with this guide.

It sounds to me as if your phone is hanging during shutdown and not truly turning off. It can happen as certain process take place that can freeze. The other possibility is a serious hardware defect/short that is pulling juice from the battery even when everything is off.
Do a full wipe and clean flash of OOS, and see if the problem continues before you reinstall anything. If it does, you have a defective phone and need to return it.
