I picked this phone up literally 3 days ago as a backup phone. it's running jellybean stock.
I can overlook a lot of its shortcomings due to its sale price but one thing bothering me is that when the battery is fully charged, it plays this loud notification sound that wakes me up in the middle of the night. I can't find a way to just turn that and only that off.
I don't have this problem with my Nexus 5 on Kit Kat or my trusty Galaxy s1 running a custom jellybean ROM. They never make a sound when the battery is fully charged and I have all the notifications on.

Edit: Duh: it was the battery saver app that was making the sound I shut it off and it was fine after that.

Last night my phone was down to like 5% so I plugged it into the charger and kept using it. It was plugged in for maybe 10 minutes when I got another bettery warning that my device was at 14% (the plug had come out). Since I was almost done, I decided to leave it unplugged since the plug gets in the way anyway. Shortly thereafter, I think the Volume+ app caused my phone to crash. It just turned off. When I turned it back on, my battery was reporting 39%! I wondered if it was a fluke, so to test, I switched to 4G from WiFi on, listened to music, and continued to use my device to see if I did indeed have more time with it. It went for another 40 minutes or so before the battery was back down to 5% and I plugged it back in and went to bed.
What gives? I feel like my battery life is exceptionally awful, but I thought I was experiencing the Android OS awake thing, since my awake times do seem to be pretty high, like 50% of my time on battery even though the screen is probably on for less than 25% of my time on battery and I only have google apps set to sync in the background. Last night's mysterious battery increase now leads me to think differently though.
Are my battery stats out of whack? I'm not rooted yet so I can't reset them that I know of. I am planning to tackle it this weekend, though. I was waiting to make sure the phone doesn't have any issues so I didn't have to go through relocking it to return it.

Normal Android behavior. I've seen it on every device I've had since the G1
The battery and the OS become mismatched if you restart while charging. The OS will report a "faster drain" when it reality itsvjust trying to match back up with the battery.

Welcome! I've got Galaxy Note 3 for 3 days and i'm not satisfied about battery life. I read that it is possible to work on one charging even 3 days! I can work on my max 8h!!! I've got wifi/bt off, battery saver mode on, screen bright on auto and -5, only gsm (not LTE), no sync, no facebook app. When i'm working on my phone i can easily see how battery is discharging When the battery is full and after 10 usage i've got 90% without doing nothing special. Is my battery broken? shoud i use warranty?
You got some app going crazy or something. I get apps that hang sometimes and will kill my battery in a day. Lately ive been paying attention and trying to kill apps that are uselessly draining and ive only used a third of my battery in 24 hours. Just gotta hunt the problem down.
Regardless, its probably just software and not the phone itself.
For some reason my battery is acting like it barely wants to charge. It'll take hours just to go up by 4% and once it reaches a certain point, it no longer moves up in percentage. Sometimes it stops at 14%, sometimes it stops at 32% and sometimes it stops at 8, it's completely random. Also when I restart it, the battery percentage is completely different than what it was before. The weirdest thing is that the battery percentage actually decreases sometimes while it's on the charger. Even when I cut the phone completely off and it's showing the battery charge icon, the phone drains in percentage. This just started a couple of days ago, maybe a week after I flashed a kit kat rom.
Did you even check your port or chord? I would flash back to stock to make sure that it isn't the ROMs fault. Though it could be the battery?

This has happened to me with third party batteries so try another battery and another charger. I'm running kit kat on my S2 and battery usage is quite a bit better.
I had the same problem, I tried different USB cables, flashed back to stock, nothing fixed it. I finally figured out it's charging port was going out. I took it to a place they had it replaced in 30 minutes, I'm now able to charge my phone fully and my battery life is back to being great.
Hello, I have a feeling my battery as quit on me. I was running the latest CM for it and one night I was listening to YouTube and my phone was charging and it just turned off. So I started it back up and then it gave me a error that androids system UI quit responding. Kept happening after a couple reboots. So I wiped the phone (just my stuff) and kept CM, and now my battery will not go beyond 5%. I had it charging while off for 4 hours and I looked at it and it said "4%" and now it will barley get past 2%, is my battery dying?
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.

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.

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.
