I'm beginning to wonder if my battery is borked for my phone. I've done every single thing out there to ensure my battery was always 100% charged and calibrated.
However, today my phone read as being 100%. Went home, charged it up when the phone was powered off to make sure it actually did get to 100%. It did that, all was fine, or so I thought. A bit later, I check my phone and it's reading 72%.
There is no way this is normal for a battery. My phone has been dropped a couple times (mild drops, not huge ones), so wondering if it's possible a cell in the battery has been borked?
Had it been calibrated?

I said it in my first post.
What ROM? Did you look at it when you removed the charger? Did it still say 100%? Was it warm when you picked it up? Did you have signal? Did you install any new apps? Did you just reboot? Did you have a random reboot?
Don't sweat it, charge it and check it again.
No ROM, just a regular Gingerbread shoved through Odin, along with CWM purple.
The phone was 100% before I put it on the charger. I only checked the phone when I heard it doing the signal lost/found noise, and that's when I saw it went down dramatically (there is NO way that attempting to find a signal can lose battery power by 28% in 30 minutes).
Phone was not warm at all.
I have about 2 bars of signal.
I have not installed any new apps.
I did not reboot.
I never have random reboots (it's a reason why I don't mess with the Gingerbread ROMs).
I'm not sweating this, I'm more annoyed. And, all people do is say "Charge it, do this and that to calibrate, turn off phone, charge it again, reset battery stats, spin it 360 degrees, read it a bed time story...." But it simply doesn't fix it some times.
Wouldn't this point towards a faulty cell in the battery?

Look at your percentage when you pull it off charge. There is a bug in the Gingerbread leaks that kills the bump charging. So while it says 100% while connected, at that time it continues to run at 100 Mhz but not charging actually killing your battery. So you can go back to EC05 stock and see if it still does it to be sure. Assuming you did reset the battery stats already with that bed time story...LOL.
I see Spare Parts has a "battery condition" category. Can anyone verify its accuracy?
Hey guys, hopefully someone can help.
I have a Nexus with severe charging, overheating and battery drain issues. It's on stock jellybean, factory reset, no extra apps installed, and the battery will discharge in about 1 hour by just sitting idle. It takes maybe 2 days to actually charge to 80%. I'm about to replace the charging port to see if that will help.
However, it's also getting extremely hot. Not just mildly warm. And this is when it's just sitting there idle. Not only that, it's staying hot when the phone is off and not even charging. The only time it stops is when the battery fully discharges in about 2 hours... while the phone is still off.
Anyone experience this?
I have a grey market Galaxy Nexus which means I can't send it in for US repairs.

sounds like its time to replace the battery. is the battery leaking, discolored, warped, or "pregnant"?

Yes, I'm also saying it's the time for a battery replacement. They are fairly cheap, so you can fix it without spending too much money.

Nope, battery looks brand new, but I'll definitely order a new battery. Hopefully the ones on eBay are really OEM.
My battery gets to 122f while charging and wifi tether. I try to keep it near a fan and it helps some. But I don't have any battery drain issues. You probably just need a new battery.

New charging port, new battery and phone still charges extremely slow and drains real fast. About 20% in 40 minutes. Takes around 30 minutes to charge 2%.
Then when I take the battery out and put it back in, the phone thinks the battery is empty (I took it out with 30% charge left). Not sure what to do at this point since the only thing left to do is replace the mainboard which will probably cost more than it's worth.
Anyone have any other ideas?
Some screen shots
Sent from my Galaxy Nexus using xda app-developers app
After threatening to throw this phone in the ocean, it started working normally.
Trying to figure out what was wrong with it, opened it up again, put back in the old charging port (which had a higher revision number than the one I bought).
I waited 1.5 days for the phone to charge to 96%. Drained it to about 20% in less than 2hrs. Stuck it into the charger again but the battery was still draining. All the way down to 7% where it seemingly stayed stuck for a day. Then I guess it shut itself off.
Went to check on the phone randomly and saw on the power-off screen the battery had charged to 100% which never has happened and especially not in less than a day.
Turned it back on, started using it and battery drains sort of normally now. Overheating has also disappeared completely and now it also charges normally.
So in summary, I have no idea if this problem is going to resurface and I really didn't do anything to fix it. Though I would really like to know what happened to have it malfunction like this for almost a month.
I've spent the entire evening tonight trying to find out why I'm getting very erratic battery performance on my Tab S 10.5. I've seen the battery jump and drop 10-30% within a half hour, I've seen the battery percentage go UP from 55% to 67% after rebooting it while it wasn't plugged in, and all kinds of other battery level weirdness. I've even seen it lock itself at random and randomly reboot both when plugged in and when running on only battery.
Tonight, I had had enough and did a factory reset, and it got WORSE! After the reset, it went from 10% tom 17% when I unplugged it. Once I did, it rebooted itself and the battery dropped to 0% and shut itself off!
I've seen other people on here complaining about the same battery weirdness, but the threads seem to mix people talking about different Galaxy Tab S tablets. My question is if I return this to Amazon and get a new one, am I likely to have the same problem? Will it be better? Worse?

For me, the biggest drain is the screen and I have it at a very low level. I put it into ultra power saving mode last night before going to bed. The batter level this morning was fine, but GSam Battery Monitor said I had the screen on for 8 hours, whereas the built in batter app shows otherwise.
I'm seeing alot of battery issues for people that root. You play. You pay.

I haven't rooted my Tab. I'm running stock.
Here's another example of what I was seeing. Once it dropped down to 0% last night, I left it plugged in and left it alone. hen I looked at the battery meter, it didn't show a gradual increase in battery level, it showed a huge spike up in the middle of the night. So it charged very slowly, then at some point jumped around 50% or more and continued to charge until it showed 100%.
Today my T800 did something similar, it was full, then unplugged, started to use it and it went to 92% in just 15min so I was like WTF, plugged to the charger and then immediately jumped to 99%, I unplugged and did a reboot and it once it was back was at 99% again, so I charged again to full and I will see later how it's behaving.
I did notice that when this happened it was warmer than usual
Mine is not rooted.
My T800 doesn't behave like that. I'd definitely return it.

Mine is doing the exact same thing. Also loses all wifi connections and I have to put in the passkey every time it reboots. It started about a week or so ago. I think I'll just return it.
Guys, see this thread. Tab S 8.4 T705. I had issue with battery too and i managed to settle it by this way.

Do you even know what rooting is? If you did, you'd know that rooting on its own does nothing to the battery, not only that but it CAN'T do anything to the battery
my battery problems solve (maybe)
Finally after reading dozens of post and trying all kinds of apps to solve the draining and rebooting of mt Tab 5 10.5 t800 I decided to replace the battery so I watched a video on you tube about how to replace the battery and took the back cover off.it was easy I used one of my guitar pics and before I took the battery out I remembered seeing a post here on xda about the battery plastic connector not making good contact so before I took the battery out i disconnected the white plastic connector it just pulls up and off and used a q-tip with some electrical cleaner on it and cleaned the contact and plugged it back in, I charged it to 100% witch I could not do before because it would stop at 98% and put the unit through the paces playing games and videos and doing every thing i could to drain the battery and the first thing I noticed was the battery life was about 5 times greater and it did not drop or reboot yet after 7 hours im at 54 percent battery life .. the screen is more responsive and the unit is running smooth as butter. I am REALLY excited and hope this is the answer to my problems because I really dont want to buy a new battery and find out it does the same thing.
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
I have never had good battery life on my Galaxy Tab S 8.4 ever since I got it in April of 2015. I did a battery test using the Geekbench app and it gets only 4-5 hours of life. And since this is just screen on time, my battery normally drains much faster. I've tried 4.4 Kitkat, 5.1.1 Lolipop, and even 6.0 Marshmellow with no real difference to battery life. I have also tried battery monitoring and battery doctor apps, as well as deleting the batterystats.bin file and even ripping my tablet apart and reseating the battery connector. I've thought about replacing the battery, but the only battery i can find is from NewPower99 and that's $60.00, way too much for a battery in my eyes.
Plenty of battery`s on eBay.

me too in my tab s sm t700
battery life is die quickly in stock rom 5.0.2
Keep your screen brightness as low as usable, avoid white or light screens as they use the most power it is a disadvantage of oled displays, I keep my display on auto -5

Downgrade to KitKat, as the other day i upgraded to lollipop and the battery was dropping 1% every other min its a joke. So i downgraded to KitKat and it gives me easy 3 days use and that's heavy use T705!
How to downgrade t705 to kitkat
I use a built-in feature to keep the screen toned down. In the display settings, there is a reading more feature where I select the apps I primarily use, including my default launcher Nova Launcher, and it tones the screen brightness down while those apps are in focus. Like right now while I'm using the Tapatalk app.

Head over to http://www.sammobile.com/firmwares/ download your firmware and flash using odin it's real simple!
Found this over at Android Central as last few days my battery has been all over the place, as it was fine before. Anyway my battery dropped to 5% turned it off. Waited a minute or so, turned it back on bat was showing 45% wow so i'm draining it again Ive let it drop to 5% again this is the 3rd run now its showing 42% crazy credit goes to rouge-hawkins
I had the same issue on my brand new Galaxy Tab S LTE version with Exynos chip. I was like WTF on the battery because the moment i disconnect it from the charger it would soon drop to about 85% in 5 minutes. Then the dropping continuous in huge leaps like from 70% down to 30% while i'm just browsing the web. Then when it came down to 5% it would turn off. The moment i plug in the charger while the device is off the battery level would start at 40%. It was erratic for 2 weeks. Good news is i was able to resolve this without doing factory resets.
What i did was the moment the battery came down to like 5% i completely turn off the tab and turn it on , the tab reported a higher battery level like 45% then i continued using and until it drops again to a lower level like 3%. I power cycled the tab again and it reported battery level at around 24%. I used it again until battery level went to 3% and rebooted it, then it reported 12%.. used it again until the device really wont boot anymore. Then i used a slow charger. I used the 1A usb charger from my other phone (while off) and waited until 100% full. Then things became normal.. it reports battery level fine after. I also installed Clean Master and disabled some background apps and Samsung bloatware that i really dont use. Everything is ok now and im happy with my Tab S 8.4... hope this helps for those who got their device over the holidays. I resumed using the 2.1A default charger and issue doesnt seem to repeat anymore.
