Hi,
I've recently got a Samsung Galaxy Tab S 8.4 T705 and it is an amazing bit of kit, but I am having an issue with battery life. I am only getting about 2:30hrs screen on time, even with the screen brightness on pretty much the lowest setting. I am currently only using it for emails (Gmail) and light Web browsing, so nothing taxing. It is not rooted and running the latest UK released updates. I have debloated the tab using the debloater v3 available on XDA. I've also switched off mobile data, WiFi scanning etc and I am solely usi get home WiFi at the moment. Just typing this post has used 4% of the battery charge
I've noticed a lot of people managing between 7-9hrs,so I was wondering if there is something I have missed or I am doing wrong?
Thanks in advance for any assistance.
Ross
Can you fully charge your battery play/loop a youtube video for 10 minutes and tell me how much has droped? And can you show us your battery stats/graph
I have a T700, only had it for a couple days, but battery life seems pretty poor. I mostly use it for email, browsing and Twitter.
I don't have a lot of apps, widgets or accounts refreshing. Disabled any apps I don't use as well.

Thanks for the reply. I will charge the tablet and then report back.
I just rebooted the tablet as I inserted my sim card and it went from 55% battery to 45% after the reboot.
@cjw_101 it's quite shocking isn't it. I like you have no widgets. Hoping it is just something I am doing wrong or an easy fix.
Bit of an update. I intended on running the battery out fully before recharging it and noticed some strange behaviour:
I restarted the device and it went from 55% before the restart to 45% after the restart. It then discharged over an hours use of general Internet use and switched off at 1%. I pressed the power button again and it turned back on with apparently 14% battery. It then ran down to 1% again over 10 minutes and it switched off. I turned it back on again and it showed at 1% and switched off again. I plugged in my charger while the tablet was off and it showed on the screen that the battery was 12% full.
Now just recharging it.

I heard from the same stuff as you are describing here. Maybe it would be the best when you bring back your tablet, that they can repair it/or replace the battery... because this is just not normal!
If you are rooted, I would try a custom rom from here: http://forum.xda-developers.com/galaxy-tab-s/development
Choose one of your choice and try it again with this new rom!
Thanks for your help.
I've emailed Samsung to see if they can arrange to fix it. Hopefully it won't take too long.
can you kindly provide a link the debloater v3?

I had similar problems and eratic reporting for the battery level.
tried all soft solutions (fully charge / discharge, reset battery stats, custom kernels, etc.) with no durable effect.
at last resort I opened it, unplugged and replugged the battery, and it has been functionning perfectly since, with something like 7 hours screen on time.
did that because sending it back was a bit complicated (import), but you may not be in the same situation.
hope it helps.
Thanks for the reply.
I've just had a phone call from Samsung and they've agreed there is an issue, so they will be sending out packaging for me to send it back for repair.
Thank you everyone for all your help and advice, it's very much appreciated
I sent my tablet off on Monday and received it back today, so I cannot fault Samsungs service. I'm not sure what they have done to the tablet, as they haven't advised me of the fault. They have supplied me with a new USB cable and adapter, which I assume is normal with battery related issues. I will report back once the tablet has charged and I have been able to test it more.
So I've been testing the tab since Friday and I am on target for at least 8hrs screen on time That's with the tablet being on for over 2 days straight as well. It looks like the issue is now resolved
Thank you everyone for all your help
I had the same problem with you. If I fully charged it and turned it off, the battery will be around 4% after 2 days. If I used the tablet, the battery drained a lot.
I sent it to Samsung Service Centre here. They wrote 'replaced Power IC' in the repair bill. Now the battery is fantastic. I can watch movies in MX Player Pro for 2 hours and the battery drains around 15%-ish only. You definitely need to send it in. It's hardware problem, not software.
Hope this helps.

In the morning, I take the phone off charge at 100%, and it will then drop to 90% within the first 5mins (with no use)
Sometimes it charges until 90% and the light goes green and it does not continue charging to 100%.
To fix this I have to take out the charger and put it back in, it then charges to 100% like it should.
Anyone else have this problem? Its really inconvenient, if its not a software issue, should I cal t-mobile to have the battery replaced?
Thanks
I'm not sure but try this: uplug the power, restart the phone and then charge it and see if fully goes through.
Someone here once wrote that if he restarts the phone while charging it (he was talking about the Hero btw) it doesn't register the correct battery charge!
Just a thought. If that doesn't work then call them to replace the battery/phone.
I read somewhere else that the phone does not trickle charging once it is full, so what is probably happening is the phone fully charges, then gradually loses some of its charge, though I'm not 100% on that.
Ah just found the link where I read about the charging issue http://forum.xda-developers.com/showthread.php?t=658338
I have seen mine do the same (once) except it went from 100% to 91% - literally in seconds though.
Some have said it's a bug in the Android OS (?)
I found updating to fw .11 has made a difference for me.
I also removed Sky Sports news app ( not sure if coincidence that it's ok again since doing both those)
May install Sky app again to see.
Sometimes apps can cause problems.
How do you check the specific level of the battery? i tried pressing it in the top bar but nothing....

Yep, upgrading the firmware and removing apps can improve battery performance.
I would suggest you pull out the battery a few times and then try a full discharge/charge to reset the digital circuit of the battery to improve the state-of-charge estimation.

Hello, I will try a complete battery drainage, til it wont switch on, and then see if it is fixed.
So far my full drains have been to 1%.
I will report back

I've been looking for the sky sports news app and I can't find it in the marketplace anywhere. I've got it on my old hero?
where did you get the app?
Just type sky news in market.
Ny phine only charged to 98 last night its now 94% after 20 mins. I hot it up to 100 but that quick a drop is not right. It's now 92%!
Ok, so last night I ran my phone down til it switched off, switched it on again and waited for it to turn off. I did this continuously til the power button no longer worked. I then took out the battery and replaced it. Then I put it on charge without having the phone switched on.
Turned the phone on today and it was at 99%. Its now 95% so the charge seems weak, but it seems to have improved since the 90%?
Maybe after a few more full calibrations it will be fine. I will try this for another couple of days and see if it helped.
After 2 days of running it down to 0 and charging while switched off, I got good battery life with the charge holding up to 100% quite well
So today I decided to charge it while it was switched on, and it charged to 100%, a couple of minutes later and its below 90% again!
I don't know why this is happening because it seems to work fine when charged while switched off, but not when its on.
What should I do?

Exactly same thing happened with mine this morn and I definitely became alarmed. It only charged to 99% when on and the charge fell very fast to 90% within 40mins of just standby - not even WiFi on.
So then I charged it to 99% while on and then switched it off disconnecting and reconnecting the charger. Turning it on 5mins later, it was back at 100% again. Browsed web using WiFi and updated all apps and widgets for 22mins continuous before it dropped to 99% this time. Been fine since.

interesting because I can't seem to get rid of mine!
T-mobile think its a problem with my battery and are sending me a new battery to see if that fixes the issue. I will post back with an update on the topic when I get the new battery in a few days.
On the phone keypad, if you dial *#*#4636#*#*, you will be taken to a testing menu. In this menu there are options to see phone and battery information as well as usage statistics for apps.

Same thing I described above repeated itself this morn except that the charge dropped to 93% within 12mins this time - on standby with airplane mode and no WiFi or Bluetooth enabled. However, It's held steady after that. I poll battery charge, voltage, temperature and usage levels using the Testing notification icon (I use the BarControl app).

Wondering if anyone else has had any battery issues? I went to sleep last night with about 85% or more battery, and 5.5 hours later my phone was dead....when i plugged it in for like 5 minutes to call my work and tell them i was going to be late...when i got to work my phone said 45% phone idle and 45% cell standby for battery use
none here - took phone off charger about midnight, this morning after alarm rang for the full 10 minutes, it still showed 100%
i've been watching it and am really impressed with battery life - is it possible you've got a program running in the background? - i had Startup Auditor to stop apps in the background but had that from before, on my Vibrant
on the vibrant,running a predominantly black wallpaper, screen brightness at 13%, putting phone in "airplane mode" when i sleep, keeping GPS off, data sync off etc, it'd be down to 17-22% at end of day before going back on charger
this G2, running live wallpaper (thunderstorm), no efficiency moves (ie GPS off, etc), screen brightness at 50%, phone still had 34% last night before going back on the charger - and the battery has not "conditioned" - i noticed on the past 2 phones batteries life got better after the first few weeks of use.
Nothing different than my nexus...and i was thinking maybe it was a game but that should have been killed automatically and i dont think it would say phone standby and cell idle if it was an app would it?
tonite you might try putting the phone in airplane mode when you go to bed, and turn off GPS
see what happens to battery drain overnite - if it diminishes then i'd look at what apps you've installed. there was an article on engadget not too long ago that some researchers had analyzed the 358 most popular apps, and found 30 were reporting data to their "mothership" that had not declared it or asked for permission to report data.
hope that helps
well another weird thing is, that when i bought the phone and brought it home, usually it comes with half battery and thats what it showed but i had to charge it quick with no apps really installed on it yet...Im charging now and will test to see what happens with battery...i just removed off alot of my apps.... to see whats up
I'm getting about 10 hours with regular usage though I wish I knew why Photobucket keeps starting everytime i kill it.
I hope you guys charged the phone fully before you used it first. That can play a big role in battery life.
I got my phone yesterday and haven't done any calibrations yet. I've been playing with it like you normally would if you buy a new smartphone. I took it off the charger around 9pm last night and at 7:32am right now I have about 60% left. So roughly 10.5 hours later and I've only lost about 40%. I'm very impressed by that. My vibrant would have been dead by now, it rarely lasts through the night if its not on the charger.

What's your time with out signal, sounds like the 50% bug to me, google the airplane mode fix, if not you might want to look into a new radio, and you should allways recal your battery after you flash

Hey guys, my nexus out of the blue started to rapidly deplete its battery. My charge will go from 100%-0 within 2 hours with the screen OFF. Yep, a total screen on uptime of about 13 seconds. I hoped the problem was with the battery itself so I bought a replacement 3800mah extended battery and it's still having the same problem, except now it'll drain in about 4 hours with the screen off.
I tried all the things I could find via search, turning off all syncs and settings I could but nothing improved it. Also I've wiped several times, there's no additional apps installed or anything, just stock. The phone seems to charge normally, taking about the same time as when it worked fine to get to 100%.
I'm guessing it's a hardware issue, but I'm out of warranty on the phone. Any of you experience something similar and was able to replace a part manually, or is my phone prettty much a brick.
Also I should add that there is no service currently on the phone since I had to switch it out, It's pretty much on airplane mode w/ mobile network turned off so it's not looking for a signal or lte draining. Another thing is that the drain is pretty consistent, meaning I could be using the phone or have it off the whole time and it's still going to 0% at the same time.
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 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.
Greetings,
I've had my Tab S 10.5 for just over 10 months now. My battery life drops 20% on standby over the course of a few hours. I was watching a video on YouTube and it dropped by 25% over 15 minutes. So, I ordered a new battery and replaced it fine. However, the same type of things persist. Today I watched 15 minutes of YouTube and the battery dropped 27% (to 12%). When I powered it back on it was 55%. So, I cleared the cache via recovery mode as other users have suggested and I'm waiting for it to charge to see if that helped. However, it's only charged 3% in an hour. Obviously something is going on. I want to say my battery life took a dive with Lollipop, but I can't say conclusively. I did downgrade to KitKat and the problems still persisted so I upgraded again figuring it didn't make a difference. Then I replaced the battery yesterday. I'm not sure Samsung will take it back but I could replace the old battery (depends if they can tell I opened the case). Anyone have any advice? It seems like the battery % isn't being correctly read by the device so I was hoping wiping the cache would do it. Thanks for any help.
Recalibration?
