Ye, my battery just went from 48% to 3% in about 3 minutes. Does anyone have any idea why this is?
Same problem here. From about 43 % down to 7 % while it started to charge the battery with the original charger. Afterwards the Tab didn´t charge at all. Battery drained and got very warm.
I Called Vodafone and was told i have to send the Tab in for fixing. I hate waiting for the tablet 3 weeks.
Update: After 2 hrs. of waiting the Tab cooled down and i was able to start it again. Did a factory reset and was able to charge again with the wall mount charger.
Just wanted to bump this as my battery life is miserable and it discharges really fast in standby...
My HTC desire has been on for 52 hours, used for a lot of stuff and is at 20% battery.
The Tab charges to 100%, I unplug it at night and in the morning it has lost approx 10%, I leave it a few more hours and it't down to around 60%. This is with no use and no apps running!
I've tried killing apps or leaving them in memory and it doesn't seem to make much difference. I also use setcpu and have a profile where the CPU speed decreases when in standby to conserve battery?!
If I charge to 100% and use it constantly, I get fair life out of it maybe 4-6 hours of light use - some streaming over wifi, web surfing, kindle, sudoku etc. If I use it occasionally or heavily though, it dies very quick and if I leave it at about 40% on the evening, it's generally dead in the morning.
Why does it discharge so fast in standby??
Check to see if it continually searching for a signal. I've noticed that mine loses a lot of power constantly searching for a signal, cellular and wifi. So, I used airplane mode to conserve power. Remember that it syncs to different services that require it to periodically download data. That may be your issue.

Thanks Chuck, I use it in airplane mode all the time and only use web over wifi (bought unconnected in the UK). Would it still be syncing for email etc? I didn't think it could turn on wifi and sync itself but only when I turn wifi on. I always turn wifi off when not in use. I had problems with widgetlocker asking for superuser permission quite often and that killed the battery quicker so I removed that until it's fixed and saw an improvement.
I'm not seeing the times that other people are though, losing at least 10% overnight and there's nothing really running.
I installed battery doctor and the times it quotes are high for different types of usage and nowhere near what I'm getting.
I'll make sure email and calendar are set to manual update, adjust brightness etc and see what happens. It seemed better when I first got it so perhaps an app is draining it? I installed system panel to monitor this but it's hard to see what is actually draining it, any recommendations anyone???
Quite disappointed at the moment, ipads barely drop 1% overnight and I'd rather not have to turn it off to conserve battery when it should maintain it in standby...
Check the task manager and see what application are running. Also you can go in settings- about device - battery use to see if a specific application is using your battery out of normal. Also , the display is generally the battery hog, you may have set it to a super high level. One last thing you may have the buggy 3d gallery app, and it will show in the battery usage.

this is an interesting problem. its very similar to the Apple Macbook Air.
The Macbook Air was very thin - very nice looking - however it needed to depend on wifi to do most things.
the association i am trying to build here is this: the Tab needs a bluethooth headset so you dont get all your calls broad-casted over speakers and that could drain the battery a lot.
for me the battery drainage didnt seem so bad and its been on for the last 36 or so hours. the battery icon didnt look like it moved so much and i was impressed considering this thing had a gigantic battery. then i loaded up a utility that read the battery and said i had 59% so my jaw dropped. not only is the battery indicator wrong there maybe rogue processes casuing the battery drainage. and this is on 2.2 which is supposed to be somewhat battery efficient.
i dont know - frustration is what i am all about here with this thing. it seems that every time i buy a new android device i want to move to another android device. no one is getting the damn thing correctly setup.
Am at work right Now, Charged the tab overnight, just few minutes ago my battery said 60% left and now the tab is completely dead, wont turn on, I ll wait until i get home to charge, fingers crossed.

I am experiencing the same thing. Tab on flight mode and charged to 100% overnight. Unplugged at 9am, still on flight mode with no apps running, and it is 88% at 2pm.
12% drop in 5 hours with no usage whatsoever is way too much imo, comparing let say to my HD2, even not in flight mode. Wonder if they have a bad batch of battery for certain tabs........
Just wanna report back after my last post. When the percentage was dropped to 85%, I did a reboot. And guess what, now it displays 95% !!!!!!
5% drop from the morning til now in flight mode seems right and okay. Does it mean the tab is miscalculating the percent left?
PS.
I have been following the voltage in Spare parts this morning. All settings are the same (no apps opened, same screen brightness and in flight mode. Only turn on to record voltage)
94% - 4087mV
91% - 4081mV
88% - 4075mV
85% - 4067mV
But then after the reboot
95% - 4040mV
Man, I am not sure whats going on here........

let me jump in here again and share a similar deli-ma i had with my X10i.
while i was messing around with some custom roms i decided to stick to one that looked somewhat nice. well the funny thing is the battery indicator would always display 100% and for about 4 hours it would drop ever so slightly. then i removed the battery and put it back in -- the battery indicator showed 0% and i got a red light flashing ....
after screwing around with it for a bit i re-flashed the stock firmware from Sony-Ericsson and magically my battery meter and my battery worked fine.
so to sum up -- it maybe a software issue like the one i had on my SE X10i above?
Hello,
I can't believe this has not been mentioned already - but I've done a search and I can't see anything regarding this subject.
I'm just curious as to the battery chart in regards the Display. It is always really high. As a test - I charged my phone to 100% and then over night left my phone alone, with the screen off to see what the stats were. When i awoke the battery chart had the display eating up 54% (even though the screen had been off all night).
Is that normal? Can the Battery useage chart be trusted?
I'm running a rooted device - with XE2.
Am I missing something here
My chart has been 100 precise for me. Post a screen shot if you can.
Also make sure you are not running NoLED.
Yep, ill sort a screen shot out.
And what is NoLED?

So you are NOT running it
It is a utility that uses your screen to display notifications, because there is no LED indicator on the phone that flashes for missed calls, voicemails, messages, etc.
NoLED displayes those little dots on the black screen itself.
Theoretically it makes the screen to be always on, and wastes extra power. But again there is a huge market for that great app (developed by an XDA member here).
Ok - here is a screen shot. Anyone else getting results like this even when the screen is off??
I got the same battery issue like you when i was on KE1.

i have the same problem, my sgs2 is so bad whit the battery life, i cant use the phone a normally working day from 07:00 until 17:00.. and allways i see the screen in the battery chart all the time whit more then 50% battery usage.
if this problem still exist, i will sold my device, thats not for a daily use..
Same answer as always .
Your display has been the part of the phone that has used most of the power used .
NOT your display is using 70% of the battery .

but did you read the first post from the theard owner? over the night, the display stay the whole night off, and use more then 50% battery.. thats not normal sorry.. a device which runs between 4 and 6 houers its a device for fun and play, but not more..
when im driving to the work i need 1 hour and 20min.. in this time, the screen is maybe 10min on while im listening music, and in this 1 hour and 20min my battery drain is 22%..
unbelivable...
from 07:00h in the morning until 12:00h 5 hours later, my battery is on 50%. i had htc desire hd before, and this device had a 1300mah battery and it was better than samsung whit 1600mah..
im really dissapointed..
The display = the majority use of the battery fact .
OP thinks display showed using 54% of the battery overnight .
It showed as a percentage of the total power consumed that the display consumed 54% so if the battery dropped 10% of its capacity overnight then 54% of that was from turning the screen on .
I repeat the battery usage shows what has been using the battery as a percentage of the amount used it does not show the battery drain ,Or even amount of battery used in that time frame
||||||||||Drained 50% of battery today display 20% .
Drained 30 of battery yesterday display 70% ..
WHY HOW AND other stuff regarding battery usage on SGS 1 forum .
jje
after the night was the battery down 54%, e.g. have you lost %46 battery over night? Or was battery down to lets say 90% but display accounted 54% of that 10% loss???
Battery 100% to 99% that is 1% used thats clean with no battery stats .
Battery stats usage shows Display 74% .
Or the display has used 74% of the 1% used .
Its a really simple reading of the usage of the battery by the varying components its not a measure of the battery .

i think we didnt understand us..
i try it again.
we start whit 100% full battery.. you dont touch your phone over the night.. and when you stand up, you look on it and see, the battery(only a example) is on 50%.. from this 50% which battery loose, 50% goes to the display.. so, the real drain from the display is 25%, over night, and you didnt switch it on.. you think that's not too much?

yes its a problem. when i do that same test on another phone, display does not appear in the list. if i charge to full at night, unplug and go to bed. when i wake up 8 hours later, the top of my list says Cell Standby, WiFi, Android OS. Display does not appear.
once i use the phone for a few minutes, display jumps to the top very quickly.

what i did:
- boot in recovery mode
- wipe data
- wipe cache
- power off
- boot in download mode
- download follow rom:
http://galaxy.androidgamer.org/Firmware/GT-I9100_XWKE7_XXKE4_OXXKE2.zip

pit file, so download it to if you want
---> finish.. other steps like root is not neccesssary to describe here.
---> i will report again today in the evening.
for me its better right now.. i found the drain is to quickly again, but really much better.. something around 22h, but whitout a lot of use.. this time on the first place is the android os in the battery chart.. display is showed on the place 3..
hoping to get some help...
i have update my SM-N9005 from 4.3 to 4.4.2 through Odin. rooted. with CWM Recovery.
tried probably 3 custom ROM that support 4.4.2 and end up on the Official leaked.Build 4.4.2 ( rooted)
the battery performance is driving me crazy.
on 4.3 stand By mode i used to loose 0.8 per hour now with the same setting same features turned on. i loose 2.3 percent per hour.
on 4.3 screen time with the lowest Brightness i lost 1 percent every 10 minutes. now i loose 3% with same brightness level. 3 percent every 10 minutes.
Android OS and Android System are always on top of screen in the battery Graph. i
media is also on top of the screen in the battery graph.
have tried a lot of solutions and factory reset with no luck at all. ( i have placed the device with Airplane mode with no SUCCESS )
installed a lot of battery analyzer apps did not have a clue who's eating all the Juice.....
any idea how to fix this??

Partial Wakelocks are usually caused by apps running in the foreground. There's usually not much you can do about that. If you are actually using the phone, battery will run out. What you need to find out is what happens when you are not using the phone.
Do this:
1) Charge the phone to 100%. Disconnect the cable.
2) Let the phone sit idle for 1-2 hours with screen off.
3) Get Kernel Wakelocks from Better Battery Stats.
Then you'll know what's eating your battery when you are not actually using the phone.
In my case, I get ril-fd, l2-hsic and wlan_rx_wake wakelocks the most. I know the causes, but I can't do anything about them without rooting.

I've noticed the first 10 percent (from 100 to 90) go away fast as hell. Use your phone as you would today, just make sure you have enough juice by the end of the day. Leave it as it is overnight and then post your screenshots.. You don't seem to have any wakelocks so your battery shouldn't be draining.. Mine is going like 1% for 8 hours or something, the problem starts when I turn me screen on lol!
I had this problem on my all my Samsung device
the only solution was to take out the battery for a few seconds
worked for me on
note 2 and 3

i am loosing more than1.5% per hour where on stand by mode... everything is switched of.f im surprised there is no wakelocks showing... ill wait till the end of the day.
its been 4 hour since last charge and now im on 93%..
im assuming the drain is happening due to the bad reception where i am at.
how do you manage 1% per 8 hours that's Awesome (knock on wood) :laugh: .. is this with WIFI and Data on?
i don't understand ... how come i have no wakelock after screen off.. and my battery draining 1.5 % per hour on stand by mode.... and android Os always on top ?
BBM.
And I haven't done anything special, actually you have to do something to NOT get great battery life while idle. After a factory reset, nothing disabled (so G+, G search and all those wake cycles still present) with WiFi off and Mobile Data ON I lost the usual 1 to 2% per 8 hour sleep. The problem starts for me when I turn on my screen, not when it's turned off

It's caused by broadcast packets sent by other devices in your network waking the phone up. The solution is to install a custom kernel that filters such packets.
My battery life was amazing when i bought the phone lasted like 2 days
Recently I got an update of less than 150mb after that my battery life is now horrible in normal mode it lasts 9 hours the screenshot i attached show my phones battery usage on POWER SAVING mode (50% used on power saving mode in 9hrs at NIGHT when i don't use the phone)
and rite now i'm charging the phone again dont know whats wrong with it.
(It doesn't overheat or anything just loses battery.)
Will appreciate if someone can help troubleshoot this issue.

First of allI would say that your active GPS is a high battery drain so I would turn it of and see again if the battery drain is still that high.
Thnx turned off GPS and restarted phone now it's fine 85% from 100% in five hours with moderate use.
So is my GPS app is faulty?
I use maps a lot so how do I keep my GPS on but without this issue, my GPS was on from purchasing time but nothing like this happened.
Hoping for a permanent fix.
Once again appreciate the prompt help.

it's hard to answer your question without any other details. do you use any widgets? any apps that might cause waking of the device? use apps that could show the wakelocks during deep sleep
I use the s health, the clock and calender and the track id however I went back to the store even after reset the issue was there They said I can change the fone but didn't have the black color ( white to me looks tacky) so I got the m8 instead. Thnx for the help.
Sent from my HTC One_M8 using Tapatalk
change location service mode to power saving when not using maps, change to gps only when you need. Turn off bluetooth and wifi tethering. Switch to HSPA when you're using map because you don't need lte speed.
As the title says, standby battery is awful.
I have all the bloatware disabled, only things on push are gmail and facebook messenger.
Cell standby is also sitting at 20% battery usage, no matter what, 2nd on the list behind screen time. Note 3 had exactly the same issue where cell standby is concerned. None of my other phones have had this issue, including my S2 with buggy as hell CM11, OnePlus One, Moto G LTE, etc.
No matter what I do, even with everything disabled and on airplane mode, there's a constant 1% battery drain every hour.
In my Note 3's case, this only happened on stock samsung firmware. When I flashed CM11, the issue went away completely. Something like 0.3% drained per hour instead.
So to me the issue is with Samsung's crappy software. I know the battery life was woeful on the Note 4 anyway before an update came in to fix things up a bit. Maybe they're saving the fixes for 5.0?
I know a new update for the N910C was released a couple of days ago too, but not available on European models yet.
Anyone else having these issues?
I dont have this issue at all my friend if i were u id try a complete wipe 1st, some people have had this issue too so returning could be an answer
Same here...
I only lost 4% battery overnight and don't have this problem too
20% battery loss on standby but mobile data was enabled.
^ you may have a bad app and/or bad signal
I have 4 bars lte at home, 2-3 bars at work, wifi always full signal at both work and home, one is ac 5ghz, other n 2.4ghz, no difference in drain either way.
Ive done a factory wipe 3 times now, even through recovery once. No change. Better battery stats and gsam both report no rogue apps, and ive also tested by having no apps installed, with and without bloatware disabled.
Im not really keen on the idea of voiding my warranty to test other kernels etc, and the only other option is to flash the ank5 update to test.
Ive attached another screenshot showijg the issue better. The drain gets noticeably worse after the first 50% or so, but that could be caused by many things, like inaccurate readings.
Like i say though, 1 of my 2 note 3s had the same issue. Could well be a faulty wifi/cellular chip.
Ignore the time its been on, the same thing happens during a day of heavy usage when in standby, same level of drain constantly.
1%+ may not seem that much to a lot of people, but with my usage i should get through 2 days regardless. It should be less than half of what it is. From the curent reporting in the battery stats, im losing almost 50% of my battery in standby over a day and a half or so.

The only things enabled for sync right now are the basic google apps such as chrome, calendar etc. They rarely sync though, and no other phone I've used in the last 2 years has had an issue with them.
Samsung sync constantly returns errors so I leave that off.
Last thing I'll be trying tonight is a full wipe without disabling any built in apps. Its doubtful, but maybe one of the core shamsung apps are trying to communicate with a disabled app or something. I really don't know.

My n910c is terrible too. 15% battery loss in 3 hours of standby alone! Wtf! Tried every battery saving trick' no location on etc...
i would suggest u do few thing while u get on bed next time,
Full charge your phone and unplug before you on bed,
1. Restart the phone while on charging,after restart go to home screen and lock the screen and unplug then go to sleep,check it at the next morning u wake.
2.Left the phone with your daily apps running,full charge and unplug then go to sleep,check it at the next morning too when u wake.
this is how i solve those apps running not right.
like the screenshot below,
An apps running at night drained 30% battery within 6hours & 30mins & without switch on the screen or touch anything since i'm asleep *with wifi on*
2nd screen shot shown that cm browser running and consume 94% of processing among 30% battery
while cpu only running 20mins since i had weather & sync on during night.
After that i report to cm team and they send me latest version,
after re-install my phone just back to normal.
now my N910c note 4 is consuming 1% every 1.5hours standby with wifi/3g connected *my area 4g only 1~2 bar so i changed to 3G*
average daily usage were 4.5~5.5 hours screen on time with social apps,browsing infomation,checking e-mail every 1or2 hours,reading news with flipboard,news app,drawing something,watch some youtube video & with auto brightness but indoor most of the time.
hope this would help you

I did a full wipe, installed ANK5 update, unplugged at 10pm at 100%, woke up at 7am with 97%. This is what it should ALWAYS be.
However, after the 2nd charge after the full wipe, it's back to what it was, if not worse. Last night I unplugged at 11pm, woke up at 7am with 92% left. That's bang on 1% an hour again.
There is nothing keeping the device awake at all. It's very frustrating.
I can only assume Cell Standby is so high due to the fact that the phone isn't actually doing anything while the screen is off. After a 20hr day with only 1 hour SoT it's sitting at 72% battery left, with cell standby at 31%, just above Device Idle at 29%. It's a mystery to say the least.

Thanks for your post. I'll definitely try restarting etc again beforehand. I'm also considering another wipe, as S-Voice being disabled seems to cause quite a few errors in the camera app. The battery drain increased after I opened the camera app too, even after force closing etc. That could just be coincidence though.
1% every 1.5 hours still seems like a lot to me, but it seems like you have a lot more apps and things running, so it's actually very good!
Very tempted to just root the thing now and throw on a debloated OS and custom kernel.
Last night i go sleep with 10% of battery left, ( im not force closing any application at all - just exit ) when i wake up ( about 7 hours of sleeping ) phone was showing 8%
No data/wifi/gps etc. If you are not using mobile internet, switch to GSM! It takes more than 30% less battery power than 3G
I'm thinking this is a hardware fault of some sort. Maybe battery, I'm gonna replace and see cause tried from full charge placing it in airplane mode to see if signal was causing the problem, didn't touch it, screen off whole time for 2 hours. Upon looking at it I saw I'd lost 7% battery! Omg! In airplane mode?! In 2 hours?! In standby?!!
In normal use there are no Rouge apps or strange readings in battery stats at all. May be hardware fault.
I've had the N910K exynos, 6 hours plus sot battery life
I've had the N910F snapdragon, 6 hours plus sot battery life
This n910c give me 3 hours sot. I'm pissed lol. Right off!!
Thats really weird, it can be issue of the battery. My 910C has about 8/9 hours of SOT ( wifi only ).

I have 4 bars lte at home, 2-3 bars at work, wifi always full signal at both work and home, one is ac 5ghz, other n 2.4ghz, no difference in drain either way.
Ive done a factory wipe 3 times now, even through recovery once. No change. Better battery stats and gsam both report no rogue apps, and ive also tested by having no apps installed, with and without bloatware disabled.
Im not really keen on the idea of voiding my warranty to test other kernels etc, and the only other option is to flash the ank5 update to test.
Ive attached another screenshot showijg the issue better. The drain gets noticeably worse after the first 50% or so, but that could be caused by many things, like inaccurate readings.
Like i say though, 1 of my 2 note 3s had the same issue. Could well be a faulty wifi/cellular chip.

Your mobile signal is very poor. I believe you have full bars but your screenshot ... well it shows us that your reception is poor. It may be one of the causes for your fast drain...

Yes, in airplane mode I should lose practically nothing withing 2 hours. Please screen shot your battery stats for us!

My SoT is fine if im only using it during 1 day. Its usually close to 6 hours. But its not heavy usage, just browsing mainly.
Let me know how the battery change goes. Im likely going to order a spare anyway for when im away from home, so will also report back.

So mobile data completely disabled? Not that it should matter much if youre on wifi all the time.

At work its pretty poor, usually a bar or two on lte, but no other phone ive had has displayed battery drain like this in standby.
That still doesnt explain why it drains 1%/hr with nothing happening at home though with 4 bar lte and full wifi signal.
Ive also noticed voice calls are taking up significant battery. A 3min call used more battery than 20 mons of screen time at half brightness apparently, unless thats normal.
If its normal, then to me the cause seems to be battery related. If not, then faulty cellular chip.
Also heres some more screenshots.
This is over the course of the day with barely any usage.
The chunks where its awake, that's just when I'm playing music, not a rogue app.
Note the big standby drop at the start, then the standby drop later, both completely different amounts of drainage, yet both when doing nothing.
