TLR Anyone willing to see if their tab pro drains battery when fully powered off. Like overnight when you're sleeping or at work. Thanks
Hi,
I got a 10.1 tabpro back at the end of Jan. I thought it would be a massive step up from my Nook HD+ (rooted) but it's not. Not only is it slower than expected the battery life is atrocious. Samsung advertises over 2500 standby hours for their 10.1 tablet, I get 200. Also I get about 6 hour video, mp4 files, not 10 and I don't like a bright screen, I know companies exaggerate but this is daft. But it's the standby that's a problem, having to charge it every few days in case I want to use it is a big step down from my Nook.
It's been into Samsung repair 4 times now and I'm currently at a dead end.
Problem
It loses 0.5% an hour on standby even with wifi, gps, updates off etc
It loses 0.5% an hour fully powered off. Fully powered down. OFF, not on standby. Just to be clear
Compare this to my nook with a smaller battery capacity which loses less than 1% a day. I've tried turning off other android devices (mobiles & tablets) and none lose battery over 12 or 24 hours when powered off.
Current situation
It's been in 4 times, it has been returned with a squeaky corner which they've failed to repair and the retail box is torn and tatty like they played football with it.
I've now been told
I have spoken to our product specialist regarding this and the decline in battery life over the 24 hour period is not considered to be unusual. In the 12 hour period where the tablet was powered on, even though the screen is off and apps closed down the tablet will still be transmitting, searching for system updates or connecting to networks or wireless. The 12% decline in battery is considered normal for this kind of activity.

This doesn't address that wifi, gps, updates etc is turned off and drain whilst it's powered off. I responded 2 weeks ago but there has been no reply.
Feedback please
1. I've been all over the internet. I've tried greenify, I've tried battery calibration, there's a ridiculous amount of bloatware that I can't delete but I've reduced apps running as much as I can. Does anyone have any other ideas?
2. What's your tablet like, does it lose battery life when powered off? I've seen people posting on here about their 8.4 inch tabpro and they've put screen shots showing better standby battery life than my 10.1 with a much better battery capacity.
I've attached some screen shots, less than 3 days and it lost 33% doing nothing on standby.
I would really appreciate if anyone could feedback on battery life when switched off, is someone able to test theirs for me?
Many thanks,
Anna
Is someone willing to see if their tab pro loses battery even when powered off?
Thanks
Uh-oh. I hope this is unusual and anomalous. I'm actively seeking a replacement for my HD+. I want to love it. I *SO* want to love it but it infuriates me that the browser crashes so often. Yours? Which ROM?
Nook is fine, It's the Samsung that's utter pants. Nook battery loses less than 1% a day on standby and screen is good. Surprisingly I thought the octo core samsung wouldn't be laggy but it is, it's not that much better than the Nook.
I have cyanogenmod 11 I think. Yes the browser crashes but that's partly because many sites are badly designed and web 2.0 is badly implemented and I use Dolphin because I like the format however it's a terrible browser for crashing. The new Guardian site I struggle with on tablets and mobiles no matter what browser for example.
Anyone willing to test their tabpro for me????
I'm actually on my 3rd day with my 8.4 it's 10:35 pm and I still have 35% left

I don't understand. 3rd day of what, off, on standby, has it been used?
Mine loses battery at 0..5% an hour on standby and fully powered off. I'm trying to establish if other tab pro's have the same level of drain on standby and powered off. Can you give me more info please? Thanks

Take the rear cover off, disconnect the battery from its connector. Bring it to a repair shop where they can do a solder work. Ask them to re solder the battery connector, this rework only takes under 5 minutes. It will fix the problem of battery quick discharge. If the problem is still the same, you only need to replace the battery, cost only around $30 for new battery.

Thanks but it was only a few months old so well within warranty.
They replaced it with an tab s 10.5 (no more tabpro's available). Tab s gives me the battery life I expect and speed. Big difference between the two is the tabpro used up a lot of battery with 'tablet idle', well over 50% whereas on the tab s it's a few %. I think the tabpro didn't quite deliver, it was discounted quickly, the software wasn't right plus squeaky case, but so far imo they seem to have got it right with the tab s. Despite the lower capacity battery and bigger screen it lasted me over 5 days and that included setting up and installing apps. The tabpro by that point would have been long dead.
I'm glad you get a new replacement but this's a common problem of Samsung tablets . Be aware of this problem is the future of battery quick discharge. Most users just simply think this is a problem of battery.

You can lower your brightness if it is not already at the lowest setting.
Unfortunately, the galaxy nexus has poor battery life. You could also try turning off data when you don't need it.

the screen is at lowest and it doesnt make sense turning of data if the problem is from screen right?
I'm having the exact same issue. Screen is totally eating up my battery life. It took 30 minutes for the battery to go down by like 10%. And the screen is 40% of the battery life issue.

Maybe I just don't use the screen as much as you, but I don't find this to be true for me. I find it has great battery life. I don't sit for hours with the screen on, but I do regularly text and check emails throughout the day, do a bit of web browsing, take some calls, and play some Angry Birds or other games in the evening. The screen is always at the top of the list for battery usage, but even on an extreme day I still have more than 30% battery left by the time I go to bed. I throw it on the charger and I'm ready to go again in the morning.
I disagree that the Galaxy Nexus has poor battery life, in general. I would argue that: all high-end phones have "poor" battery life because of all the things they do (especially 720p screens), your personal use of it consumes a lot of power and you could benefit from an extended battery, or you have a faulty device.
hi there, i do that exact same things with no games, so less usage but i get less than a day... i love the phone but the batery is just no working...
I don't understand why people don't get that when you have a screen that is 4.65'' it will destroy the battery life. My screen use is always at 60% or more but yet I still get good battery life. The screen is going to use the majority of your battery when compared to other things, that's just how it is.
sorry but thats not the point, when you pay 700 for a top phone, that is suposed to be the google experience to carry arround wiith you and you can only get 10 hours of battery time something went wrong in the process...
Most phones are $600 to $700, and name one 4g phone that will last more than 10 hours with moderate use and no extended battery, just not going to happen. You need to reset your expectations.
GN battery is giving lots of trouble, too. I picked up the phone from charge and it was 100% charged. ! hour of usage with 3g on. Usage includes 1 hours or music and reading of pdf books simultaniously and battery is dropped to 61%.

I think you should take a look at every other android phone that has come out with the same specs in the last year. Everything from the EVO 3d to the thunderbolt have their default battery's not last more than around 6-8 hours with constant use because of the screen & processors.
THis is why Verizon offered the extended batteries at a discounted rate right off the bat, because default batteries have never ever lasted that long in topof the line smartphones. FFS the new iphone 4s I've heard from a friend that their phones don't even last 24 hours.
I have a galaxy nexus, and mine has lasted... let me see.. one sec...1 day 3 hours and 25sec's with 35% left. (of course I have the extended battery) but here's the kicker: the extended battery has basically the same back as the regular phone does. so if they so desired, verizon could technically put out another extended battery just like all the rest of the phones, but they might not do that. I'm content with the battery life as it is almost identical as the droid X from which I came. The only difference is since I have a lot of un-updated apps for ice cream sandwich one of them is using "mediaserver" A LOT. I'm talking about that being the top of my battery draining with the screen being second. They both have taken ~20% with android OS itself taking 13, PlayerPro taking 13, and other random things like calls and txt msging taking ~10% each.
So I would suggest not trying to watch a lot of stuff on your phone while on battery, or don't expect your battery to survive long while watching stuff on that great screen
hymn thanks for the feedback so the only solution I see would be to go for a bigger battery. I'm from Portugal were could I buy one and whays the power?

If your screen usage is less than 50%, it be more worried about what else is killing your battery........
I recently got a Note 8 (for the pen) after having a Blackberry Playbook. The Note 8 charges fine, but if I put it to sleep overnight (with a full or nearly full charge, I find a low battery notice in the morning, or it does nothing unless plugged in. The Playbook will go down by maybe 10% overnight. I used the app manager to turn off all the applications I can see. Samsung support chat had me reset the device to factory settings, but the battery is still not sleeping correctly--or is it?
Since the playbook is heavier, I assume it has a heftier battery. Maybe you simply must power down the Note 8 at night? I like the device, but if I got a lemon I had better return it now.
What is the normal battery behavior on this thing? Thanks for any help. (BTW, I am a total android newbie and not looking forward to spending yet more hours working on this.

If you look in the battery option in the settings menu, it will give you a breakdown of the battery usage and should help you identify what the main culprets were in eating up your battery. My guess it would be having all the connections (GPS, wifi, etc on while the screen is off). It could be something else, either way that should help you narrow down what the issue is. Click on the graph to get a view on the hardware usage.
take it back; the battery shouldnt go down more than a % or 2 every hour when idling, so you got a dud..

hi
(i stated this in another thread while back),
i am on stock rom,not rooted and leaving Note8,in standby, overnight i get +_ 1% drainage for plus9/11...12 hrs..
i ran n test to see my battery drainage, and did 25 hrs on 6 % ( from 100% down to 94 %)
in this period i connected to web,twitter update weather update,google play update ,otherwise i left it to see results ..see screenshot
i would say its a 3 rd party app or otherwise you did not" tweak" ...3g off ,location ,etc.etc it right
My battery drain is excellent.i have had Note 8 for a couple months and also have the note 2
the note 8 gives better battery service( slightly ) but better ..in my case..
good luck

This. Don't even waste your time trying to resolve the problem. You definitely got a lemon.
Thanks--now store or Samsung?
Thanks to everyone for the replies. I just did a different kind of reset with Samsung--holding down buttons rather than going into settings. We will see. But if the problem persists, am I better of returning to Best Buy (I missed their fifteen day return window by a day or so) or using the service request directly with Samsung? (The store involves a bit of a drive.)
Update on battery
I just wanted to post a quick update. The hard reset (holding down the power and volume up buttons together) seems to have done the trick. At 1:30 today my battery read 83% and I have had it in sleep mode for 5 hours now and it is reading at 82%. Unless it is just that the meter is wrong, the Samsung Support Chat process SEEMS to have worked. I will try tonight and make double sure.
Once again, thanks to all who replied. The information really helped.
If you got a lemon, I joint to make a big lemonade!
I have a 5120 LTE.
After a full charge it doesn't last for half a day.
I paid attention tweaking everything: from LTE to 3g, saving energy mode, screen light, wifi on-off, gps etc.
Now the point is: I wanted this tablet to do a lot of things and it seems I can't really do anything.
And yes I already have a hard reset.
It's rooted so the guarantee is spoiled.
I hope 4.2.2 release will help me somehow.
Anyone suggesting a good tutorial to change the battery?
How long you guys charge Tab S until fully charged? is it normal if my tab S fully charged only 1hour and half.. It suprises me cause Ive never have tab that can charged this fast. Im afraid my Tab have battery problem.

My 8.4 takes about 2.5 to 3 hours on average using the stock travel charger. The 10.5 longer because of the larger battery.

i noticed this on my tab 8.4LTE too, the battery simply drains away, almost close to rendering the tablet useless as I use this as my primary phone. tried playing online games and 30 mins later, it ate 40% of the battery (no unusual warm ups) i had this tab for almost a week now and it's still the same. i'm getting worried that i have battery issues

I was getting worried as well. Every time I've used it for anything other than movies my battery percentage has dropped like an aerodynamic rock. Browsing, games, magazines, etc. Movies (assuming because of the typically large amount of black pixels) look fantastic and the battery does quite with them, but for everyday consumption it left me concerned.
An hour ago I asked Amazon for an exchange which they did no questions asked. Perhaps round 2 will fare better. If not, I'll shed a tear as I give up this amazing display for another device altogether.

Yes. Lte version as well. I noticed that when he do wifi file transfers and other stuffs. Batt will drain as well.
I want a heads on comparison with his tab but it's hard since we use the tab differently. This is my primary phone while his is for browsing only. Tomorrow. I'll try to transfer s huge file via wifi and see if we'll have the similar percentage of battery drain. I already did the calibration as advised from another thread and it seems to work. A few more charge cycle might do the trick.

Same for me.... It takes forever to fully charge it (10,5 in)
I use a 10.5 LTE and it takes about 5 hours to fully charge. I recommend to switch it off while charging because when it's on you loose about 500mAh (also if the screen is off) and with a 2Ah charger if the battery sees (optimistically) 1.5Ah it takes 5h 20' plus the time required by the slow charge when it reaches 85-90%, so more than 6h.
Anyway I charge it every time I can when it goes under 50%, it's a big battery and needs a special care. Nothing to say about batterylife, excellent.
Most tablets/phones fast charge to 80% and then slow down for the last 20% , so if you don't need a full charge just grab it after it goes past 80% , your battery will live longer as well, as the closer you charge to 100% the more damage is done to your battery, it`s very small but it adds up.
Have a read of the link below, if you want to make the battery in your tablet live longer, if you have the money to easily replace it then don't worry, charge away

John.
New here and new to Android. I'll try to make this as brief as possible:
Two weeks ago I purchased a used "refurbished" Galaxy Tab S 8.4 with Lollipop installed. I very much wanted to try to make the slow but gradual switch from iOS and thought this would be a good place to start.
Battery life is horrendous compared to iPad. Here is the issue broken down:
Powered on. Battery drains at the rate of 1 percent an hour in standby.
Powered OFF. Battery drains at the rate of 1 percent an hour.
Powered on and using for web, video, etc (no games). Battery drains at the rate of ~10 percent every 15 minutes or so.
What I've done:
Wifi OFF except when in use
Location services OFF
Sync OFF
Bluetooth OFF
Screen at just below 50 percent
Wakelock detector finds some activity (mostly Android battery "WLAN" monitor stuff)
Did full restore
Most importantly: I REPLACED THE BATTERY WITH A BRAND NEW ONE and am seeing nearly identical drains as I did with the stock battery that was two years old
I have scoured the internet, rooted the device to try to kill any rogue activity, and "reseated" the battery connector 3 times.
Can anyone tell me WHY this battery is losing one percent an hour while completely powered off?
One clue is that, with everything turned off (listed above) the battery drain is nearly identical when off as it is when it is "sleeping" which would indicate...well, something.
I'm frustrated that I have been focused on fixing this issue rather than enjoying my "new" Tab S.
Any help would be greatly appreciated.
Thanks!
EDIT: I have read through other batter drain threads here and, although others share similar problems, don't have an answer. Maybe there is no answer?
I had a similar battery drain (when the device was off) 1.5 years ago with my couple of months old tablet. Had to take it to warranty repair twice, on the second attempt they changed the battery connector and the power circuit (if I remember correctly), and that was enough to fix the problem.
If the tablet drains the battery while completely off, it's clearly a hardware issue.
I'm thinking hardware has to be the culprit too, at this point. Very frustrating as this is a used tablet and out of warranty. I have done everything possible to try and get decent battery life out of this thing to no avail. I'm loving android but have a bad taste in my mouth as to their hardware. Should I keep or just get a couple hundred bucks on ebay? I'd be thrilled with this if the battery life came anywhere near the iPad mini.
The 8.4" is known for having a problem with the battery connector (maybe flexing of the case makes it loosen), some people have soldered the battery wires directly to the motherboard and say it fixed the problem, Samsung knows there is a problem with the battery connector according to some service centers, one service center actually fitted a more heavy duty connector to fix one problem according to what i read.
John.
I would contact the seller and try to return it and then get one from a different seller.

Hi,
I've been using this Tab S since July 2014 and been very pleased of it.
I only use it every night for Web browsing or watching movies.
Not any games or any social network or anything draining the battery.
Average autonomy was around 7 to 8 hours.
9 months ago it has started to drain a little bit more and especially when off (totaly off, not in sleep mode)
Before that event I was turning it off at night and 24 hours later the battery level was exactly the same. (zero percent of drift)
Then it started to suck a little bit every day: 1%, 2%, 3% each 24 hours when completly OFF.
First thing I've done was to make a wipe cache/data and restore to factory settings from recovery mode.
It didn't help.
Then Samsung released Lolipop Upgrade so I did it.
It didn't help any more.
So I ordered a new battery to an official dealer and replaced it.
You know the answer.... didn't help.
Then Marshmallow has come and I did it.
.... idem.
So as electronics and automation technician I am, I decided myself to do some measurements.
I opened the Tab S and checked battery voltage when off every hour with a high accuracy Fluke D.M.M.
And I found that it was loosing ~34mV every 24 hours, which makes the 3% loss.
(Boring calculations just for knownledge : LiPo Vmax 4350mV - LiPoVmin 3200mV = 1150mV corresponding to 100% capacity.)
First thing I did after that was to make the same check but with battery disconnected to the Tab S.
And you know what? not even a mV drained in 24 hours when not connected to Tab S PC Board!
Then I measured the resistance between + and - socket on the PC board : value between 800KOhms and 1,2MOhms.
Same values when I crossed the wires.
Theses values are too low, I should have found many many MOhms.
I've also checked the battery connector that some other guys said it was loosy or bad soldered: that's not the case but I've soldered it.
same problem.
MY CONCLUSION: it's a hardware problem.
Maybe it's a drifting component, probably a capacitor which as lost insulation, or a defective diode.
Unfortunately I don't have the diagrams of this Tab S and can't diagnose it.
Is there on XDA any guy from Samsung Tech Support who can help me?
No answer?
Anybody has Galaxy Tab S 8.4 diagrams?

i had the same issue Android – Marshmallow Android – Lollipop etc battery life sucks on the upgrades.. The battery would not last more than 3/4 hours, it was a pure joke. Best thing is to downgrade to KitKat XXU1ANF8 since my downgrade battery easily last a few days of heavy use.

Hi guys!
I have a serious problem with a used A5 (2017) I got from some friends. The battery life is abysmal. I already changed the battery and it didn't change anything.
It is running on Android 8 Oreo. The most serious problem, I think, is that the phone even discharges when it's powered off. I tried using the latest hadesrom, but it didn't changed a thing. Lifetime is around 12hours, doesn't matter if I run some apps or just let it lie around in standby. I tried factory rests and some battery saving apps... nothing works. Is there any way to get better battery life? Thanks in advance!

Lifetime is around 12hours, doesn't matter if I run some apps or just let it lie around in standby. I tried factory rests and some battery saving apps... nothing works. Is there any way to get better battery life? Thanks in advance!

You could try the naptime app. But I don't think my battery life is any better than yours.
The a5 2017 has a famously good battery life.
I am not a heavy user - make and get few calls and mainly use it for receiving emails and a few texts plus a bit of web browsing.
Occasionally listening to podcasts.
3 days battery life is easy for me - reckon I could get 5 days if I just left it sitting quietly.
If it's going flat quickly even when switched off, it sounds like a fault somewhere.
Don't know what else to tell you.

I never tried letting it sit, but if I just left mine alone it would last for days too. But if I am gaming on it, it will go down to around 50 percent at noon.
wow - 3 days life battery!! I can hardly get to 2 days, without heavy us - but I would never try to change the battery -> sounds too complicated
One thing that is worth looking at is the Always on Display (AOD).
I found it sucks a lot of power despite the claims that it 'doesnt use much'. It seemed to use around 1% an hour - I guess thats around a quarter of your battery in a day. So unless you find it useful either turn it off - or set it on a schedule for when you actually want it to be on.
Battery life is always sujective and depends on what your phone is doing - gaming will burn through a battery like nothing else.
The OP said the battery drains even when the phone is switched off - That sounds like a hardware fault. The battery will gradually drop when switched off - but it should take months for a healthy battery to drop much if the phone is switched off.

1 percent an hour doesn't matter to me lol. I am a heavy user so I charge every day anyway.
