Hi,
Bit long story, I know, but I'll have rooted Galaxy tab 3 8.0 and the problem for few weeks has been that the battery has gone mad.
So, when battery dies and tablet shutdown and I try to start again after a while there's no enough juice to even start fully or if it starts it shows 1% and shutdown immediately. That's as it should be I guess.
BUT, if I plug into charger when batt is empty and it has shutdown it suddenly shows very random percentages like 12%, 45%, 52%. 75% etc totally random even it should be something like 0%-1%.
If I then fully start it android shows that same big percentage but batt won't last a minute if I plug off the charging cord.
If I then plug in the charger again when it has shutdown it may show totally different percentage than last time but also dies as soon as I plug off the charger.
First time it could be like 12% but immediately after shutdown suddenly 71% etc.
Also when I try to fully charge battery it often jumps from around 70%-80% to 100% and while discharging it can suddenly drop from around 45% to 1%.
I have tried many things like wiping batt stats and fully charge from empty to full with power off/on, restart after full and charge again, leaved it screen on to slowly kill the batt etc.
So is that batt just badly worn after many years or is that "battery information file etc" somehow messed up that it can still be fixed/calibrated?
Ouh, and my current rom is AICP 12.1 (Nougat 7.1.1) if it matters.
Thanks

Hey XDA, I just purchased a new AT&T SGS3 and I'm having some issues with the battery on the phone.
When I charge the phone overnight it charges to 100% then when I unplug it, the battery drops tremendously in about 5 seconds down to anywhere from 50%-75%. I tried manually recalibrating the battery by charging it 8+ hours, removing the battery, charging again while off, charging it again while on, then restarting. That seemed to work for one charge and the battery acted the way that it would have on my Nexus S.
However charging it again after a full battery drain, the same thing happened.
Also when the phone is low on battery, it displays the normal battery messages, but then the screen stays on, draining the battery faster.
Solutions? I want the root the phone, but only after I have these issues sorted out. (I'm still under warranty right now)

Did you try a reset of the phone through the settings ? After that try charging to 100% then drain completely and then recharging without break then use the phone mormally and try to recharge only when it hits 10% remaining for the next 2 or 3 charge cycles and see if that helps

Looks like a bad device. I would send it in if i were you.
Hey guys, I've had my phone for 4 or so months now and I always charge it while my phone is off and never had any charging/battery issues until today, I decided to charge my phone while it's on and it charged up to 25% and I restarted my phone without removing it from the charger and after it booted back it it's showing 50%, I restarted a few times, tried a cold boot, it's still 50%.
Is this a known issue with this phone? does anyone know what's causing this? I've never had this happen before.
EDIT: After this happened I ran my battery to 0% so I can attempt a battery calibration and when I poped it on the charger it showed my battery was actually 0% and showed a yellow hazard triangle thing (normally it only drops to 1% and there has never been a yellow triangle before)
Sometimes the Android system can incorrectly report a battery charged. I have had it happen to me on my Nexus by about 10%, but have not had it happen to me on my G3. I would not worry about it too much if it only happened to you once. If in continues you to jump around in battery percentage, then I would suggest getting a replacement battery. Keep in mind to try not to leave it charging for very long after reaching 100%, from my experience it can effect a battery's ability to hold a charge if that is done repeatedly. Which means do not leave it charging overnight while you are sleeping. Also I would not suggest running it until 0%, I would imagine a sudden shut down of the Android Operating system is not a healthy thing for it either. Just like it is not good to go up to a computer and just pull the power cord.

Thanks for the input.
I never leave my phone on the charger while I sleep since it only drops 1% while I sleep. My phone actually only goes on the charger like 3 times a month
I know it's not good to fully drain the battery very much, I was just draining it to attempt a battery calibration in the os. And when I do this my phone usually only drops to 1% then dies, but all of a sudden it dropped to 0% this time and showed a big yellow triangle with a big exclamation mark in it
Anyways I reflashed my rom in hopes I can flush the problem out. In 4 months of owning this phone I've never seen this warning before.
This is almost exactly what happened with my old phone (Samsung Captivate Glide). If this continues to happen, it is one of the first signs of the battery failing. But if this is a one time thing, I wouldn't worry about it.
In my case, the battery was going bad. It started going from any % battery, down to 0 instantly, forcing a shutdown. After rebooting, It would show a decent charge (~60% most of the time), but would do the same thing within 5 minutes. At first it only acted up like this once a month, but it became more and more frequent that it happened every day, after using the phone for only 15 minutes. The only fix is to get a replacement battery.

tyvm, This is extremely helpful info to keep in mind. Now that you mention it I have seen the battery kinda swollen up a couple times when it got hot, only ever so slightly but I did notice it.
If my issue persists i'll defnitly try a new battery, thanks for the tip
Hi everyone,
My G3 (D851 T-mo, not that it likely matters) yesterday shut off dead at about 40% battery reported as remaining. I was early to a movie and fired up Angry Birds 2 to kill the time. Just as I was about to start playing the phone went black. Tried turning it on, nothing at all happened. I had noticed the battery was at 41% just a minute or two before. Usually this means I have PLENTY of juice left.
After the movie I tried turning on the phone; again no response at all. Pulled the battery, replaced it, still nothing.
I got to my car and plugged it in to charge on the way home. After a moment the screen came on and gave the "powered off charging" screen showing 71% battery remaining. Huh. 71% ?
I was driving for about 10 minutes, got home, and plugged it into a wall charger. At this point the phone (still powered off) reported 51% charged.
Shortly thereafter, I booted the phone up and it reported 55% charged on the usual battery % notification.
I charged it to completion, and all seems normal, but I'm worried about it dying again at ~40%. I frequently run the phone down to 15-20% before charging in the normal course of events. Is there some battery calibration I should run? Or, is it time to get a new battery (and if so, any recommendations...)?
Hi, I picked up my phone from repair shop a week ago and since then when my battery goes below 55% i get message that battery is 0% and phone is shutting down, and then I put it on charger and sometimes it starts recharging from 1% but sometimes from 55% and if i charge it to 60% it works normally, but when i charge it to 100% it turns off on 55%, can someone help me please is it problem in software or maybe it is problem in battery?

It sounds very much like this:
http://forum.xda-developers.com/son...ttery-reporting-phone-dying-suddenly-t3095120
I replaced the battery and it's been working well for a few months now.
Battery drop from 50 % to 0 %
I had the same issue.
After force shut down (power + vol-up for 10 sec), the battery went back to normal.

EDIT :
That was a short lifesaver, battery is "fubar".
Guys , maybe there's something wrong with the battery charging in Amami . I have two Z1C, one of which normally charge up to 100 %. But the other charges the battery to 100% only in Stock 4.4.4 ... In all versions of Lollipop (stock or not) battery charges to 82% ... Calibration of the battery does not help. I replaced the battery - no change. I tried another powerful charger by Samsung - without effect. Anybody have an idea what's going on ?
The phone suddenly stuck at boot screen and was not able to load the system. whenever it loads the system it crashes BUT this issue was over when it was plugged into the charger.. the phone worked fine and battery is 52%.
I charged it fully 100% and wait an hour more and i calibrated it.. but once i removed the charger plug .. 1 min and the phone turned off and started bootlooping not able to boot the system without being plugged to charger.
so i bought a new battery... this battery also made the phone turn off at about 30% " without any warning of low battery" and not boot saying it is 0% and i put it on charge and charge it up to 100 and again stops around 40%/ this battery charges fast tho. according to the % displayed.
I m now going to charge the battery for 4 hours as I read since it is new, it should be charged for 4 hours.
Am i having problem due to battery or the phone is not estimating right the full charge of the battery or the phone have something corrupted or also the new battery is bad?
