Since yesterday, my Z00A has run into a serious problem with the battery. The phone is fine until it gets down to ~65% and then it shuts down without warning. If i try to reboot, it won't work unless I plug it in.
The really confusing factor is that if I boot into recovery or bootloader, the phone will continue running. I just had a shut down and tried to reboot a few minutes ago. The phone shut down within a few seconds of reaching the lock screen, which still said the battery had 64%. I've rebooted into recovery and the battery is now down to 57%, but it's not shutting down.
I've tried to do a factory reset including a full system wipe and reinstallation. I'm running 20170902 Lineage 14.1. I've already done a factory reset and tried other versions of the ROM. I get the same result every time.
Seems like it's a hardware related issue, may be battery or with the main board.
Its the battery, same problem happened to a lot of people including me (mine shuts down at around 30% tho)
You need a replacement, good luck getting an original since asus refuses to sell the battery and all the ones on ebay and other sites are knockoff
Some users report said knockoffs don't work at all and now they are stuck with a phone that only works when charging

Hey,
I'm in a bit of a panic ...
my cell phone ran out of battery life. When I came hame I pressed the power button and he showed the boot screen. Then I plugged him in en left him there for a while. Now , coming back, I tried to boot again but nothing happens. When he's unplugged from the power socket, he doesn't do anything at all, not even bootloader. When I plug hiim in he get's into a loop. He boots(shows black Touch Pro2 sign, red led goes out) then he immediatelly goes to black screen again (red led goes on again) and does this in a loop. Also when I can get to bootloader (rainbow screen) for 3 seconds, power off instantly again)...
I have done a HardSPL and installed Energy Rom 2 weeks ago..;everything worked fine (more or less, had at least 1 crash every two days, but better then the crash every day with stock rom)...
A phone of 600 euro's, I hope it's not bricked Any solution or can I send it in for repairs like this? Rom flashing voids warranty I suppose?

This is common when the battery is below a certain threshhold. Until it is charged above that the phone will not boot. If the battery is not taking a charge then it's time for a new battery. Yes, a non=OEM ROM will void your warrnty. Do not send it in for service with anything but the stock ROM and no HardSPL on it.
but why does it boot by itself, when plugged in, followed by power off within 2 seconds? There was nothing wrong with battery before this? Shouldn't it be a steady decline instead of being wasted just at once?
It will try to boot, but the phone will not run on just the AC power and if the battery is too low it will go into a reboot loop. LioN batteries can just go bad and stop taking a charge. That's why I have 2.
Are you near a place that has this phone in stock ? or a friend that has one ? if so go there and ask them to let you use the battery for a minute, power the phone up completely , then shut it down properly, take out battery, then put your old battery back in , do not power it on , fully charge it. You should be good to go...
after leaving the battery out for a night, he charged normally and booted normally...fieuw..bit strange, but will not ask any questions about it ...thanx for all the help!!!
Yeah, I knew it eventually would. Happened to me once. I think it has less to do with the battery and more to do with a glitch in the phone reporting that the battery level is low upon boot when it really isn't.
Completely stock T-Mo m8. Been running Lollipop since the OTA came through, and it has worked fine for the longest time, no problems other than a bit of lag, even after clearing the cache.
A couple of days ago, the phone began to shut down whenever (seemingly) any app was launched when on battery, and then would not boot on repeated attempts. It doesn't seem to make it past the first stage of the bootloader (first HTC screen, pre-animation), most of the time. Sometimes it will make it to the T-Mobile animation and then give up.
While plugged in, it boots and works fine 9/10 times, but sometimes gives some resistance to booting. If it is unplugged and any apps are launched, it shuts down as if the battery were removed. Though, the whole while the battery seems normal, no weird fluctuations or sudden drops in battery level.
If it is unplugged after having booted and it is relatively inactive (no apps launched, or any processes, i.e. alarms, syncing, downloads, etc.), it will remain powered on.
I have attempted to Factory Reset a couple of times, and cleared the cache a couple of times. The problem persists. I can boot into recovery, though I am not rooted.
Is my battery in need of a replacement or some such? I would like to remain fully stock if at all possible. I may be able to get a replacement phone out of T-Mobile, but would also like to avoid that.
Try to RUU. Otherwise, it may be a battery or other hardware issue. In that case, a warranty replacement is probably your best course.
Agree that modding the phone is not recommended, since the phone is fully stock, and it looks to be a hardware defect of some kind (covered under warranty).
Ah! It's been so long since I've even had to connect my phone to the computer that I'd completely forgotten that RUU is an option.
I'm trying it now, thanks!
Model: Tab S T805M (that's the 10" with LTE) rooted and stock firmware. I've had it for over 6 months and nev er had any issues, ever!
Yesterday I fully charged the battery using an original Samsung charger (from my late Nexus 10) until it was full.
I then used it for a while (basic stuff) then installed a game (Hill Climb Racing), played for a bit, then let it sit on the coffee table. Naturally, it went into sleep mode. Once I tried to turn it back on, about 30 minutes later, it was dead.
It doesn't have a SIM nor micro SD card in it.
I tried the key combos to get into bootloader or recovery, no go.
I tried holding power button for several seconds, no go.
I tried connecting the original charger that came with it, no go.
I hooked it up to my laptop, the same I had used to root the thing months ago and has Odin and all drivers installed and everything, no go. It won't even acknowledge there's some USB device connected.
Then, for some reason, while still connected to the laptop, I was randomly pressing buttons on the tablet (out of mild desperation, I was tired, just wanted to get it fixed and get some sleep) and I saw the battery logo again. It was at 99%, the way it was wen I last used it. So I unplugged the tablet and booted it normally.
Then, again, I used it for a while, connected to my WiFi, everything normal, and once it went into sleep mode, it died again. No buttons, no USB, no response to charger.
So, the problem is repeatable, but I haven't figure out yet the exact procedure to bring it back from the dead.
I'd like to fix it, even if I need to flash the stock ROM back on and lose root. If that's impossible, I'll settle with a tip on how to reboot the stupid thing once it enters this state. Then, eBay, here we go.
KNOX was tripped when I rooted, so I guess I can only try my luck with the warranty.
I think you should start your post letting people know that you have rooted and flashed your 10.5" and not in the last three lines.
Do you think your battery level is being reported correctly, as if your tab thinks you have 90% left when you only have 50% , then you game and use 50%, and think you still have 40% left but when your battery hits 39% it will just die, no battery warning or anything.
Flashing a tablet can cause the battery to be reported incorrectly, since you are rooted, download a free battery calibration app off the play store.
You say you have had your tablet 6 months, if you game or use other apps that rapidly drain the battery, the battery might be failing.
Since you say the fault is repeatable i would have the tablet replaced, flash it back to the stock rom and remove the root, Can you reset the KNOX counter, I think i read you can somewhere on this forum.
Good Luck

Yes, I did mention in the FIRST line I had a rooted device with stock ROM.
Tonight I was just able to enter bootloader and stock recovery and did a data wipe / factory reset. Let's see what happens now.
I'll install a battery tool to see what's really going on. Maybe my battery is ****.
GSam is the battery monitor i use, have a look at the alarms in the setting, I have them all set, I got a high temp alarm while my tab was in it`s case while i was asleep in bed, I remove my tab and the back was hot, just shows what can happen when you think your tablet is sleeping.
I bought my 10.5" before Christmas and it has never been turned off or rebooted, I have about 170 days continuous use in the battery settings, so it`s been quite reliable for me apart from that little temp hiccup.

Strange symptoms started a week or so ago. Phone works normally while plugged in to charger, and seems to get up to 100% as normal. When taken off of charge, it will slowly drain as normal...
But then, for example, it will be on 95%, and then just turn off (or maybe say the "Shutting down battery low" screen, then shut down). When I turn it back on, it might say 92% (dropping a couple percent points.
OR, when I turn it back on, it might say 3%, and be almost dead.
And then after a while obviously it will shut down again, as the battery is almost dead. It just did this from what it said was 3%, but when I restarted the phone... it now says 85%!!
So yeh, it seems like it can't decide if the battery is full or drained or both. I have tried full restarts, and this is a factory reset phone at the moment too so totally empty and on stock ROM. Not currently rooted either, as I restored everything to stock recently.
I'm assuming the battery has broken itself, somehow. It seemed to happen very suddenly though, as it was working a couple weeks ago. But before I sell it for spares/repairs, I thought I'd ask in case there was another possible cause!
edit: Also, once or twice when the phone has restarted, it has gone to the "Android is Starting Optimising application 1 out of 144" screen, where it configures all the apps? I thought it only did this on a factory reset, or after installing a new rom or something. Weird.
Yes, sounds like a dead battery:

Quite a few of us have had something similar and replacing the battery fixed it for me.
Early on this year i had an idea of installing nethunter on my old Nexus5X well everything was smooth untill i forgot about phone being in middle of installation and where it prompted me if i want to keep this system read only, I havent noticed that prompt and it automatically selected it as default. As nexus booted into nethunter everything seemed okay untill i launched app, phone froze started to heatup and drained whole battery. After that i charged it for few hours and still no powerup there was only red flashing light as indicator of drained battery. Pressing buttons in any order did nothing didn't even got charging up icon on screen. So i thought that i hard bricked this phone. Put it aside and few months later had an idea of taking it to scraps and mybe sell individual parts as screen, battery and body for few moneys. I unplugged battery and said to myself "its gonna power up rn, i can feel it" and it actually did. So my question here is did it fry the battery or connector on mb or just some messed up corrupted bloat preventing battery to charge up(didnt flashed it to stock yet so everything is set to read-only)
So I tried to install stock rom and realised that because i have to unplug battery it wont boot just loops endlessly.
If you don't mind you could order a cheap battery replacement and try with that one. Sounds like it fired the battery, but it could also have damaged the device (BLODed).
