Ok, have had a new Galaxy Tab 10.1 for three days, and the battery is draining at a horrible rate. I left it this morning with 29% at home. Came back 12 hours later and the thing is dead. Rebooted and it confirms it's at 2%.
This can't be normal, can it? I've tried fiddling with the settings- turning off wifi, turning it on, etc... but this is just horrible.
Anyone have suggestions or settings I should flip?
yeah something wrong there. might want to check check your running apps, or if possible do a factory reset. I'm assuming you didn't root it yet. my tab does not drain at all when idle

It's definitely not the Tab in general. Battery life is fantastic. Mine loses not one percent when I don't use it.
Try setting the Wifi sleep policy to shut down Wifi when the screen is off. Then there are the standard procedures like turning off GPS and Bluetooth when you are not using them. Also there is a pretty comprehensive battery statistic in the settings which should help identifying battery hungry apps.
Make sure you have WiFi set to turn off when the screen is off, I think it is set to always on by default.
When the tab is asleep with all radio's off the battery should drain about 1% per hour. There are also apps available in the market that can also do some pretty detailed tracking of what is draining the battery if you continue to have problems.

How much percent does your battery go down over night when you sleep? When i first got my tab it literally went down at most 2% and usually it was 1% or none at all.
After using it for 3 months and having a ton of APKs installed on it. I just installed Galaxy task's fat 14 and my tab died while i was sleeping, and I went to bed when it was around 18%
how is everyone's elses battery consumption during the 7 or 8 hrs of sleep?

dude. you answered your question yourself. "After using it for 3 months and having a ton of APKs installed on it." you have apps running in the background and who knows which one is going crazy. i have apps on my tab and at most i'll lose 3% while sleeping for 8-10 hours. you issue has nothing to do with the rom. it has everything to do with whatever app is going haywire.
I wasn't trying to blame it on your rom, its great, I'll investigate the apps/games i installed.
but i was using your task v12 for several weeks without this happening. Maybe something happened to my settings when i upgraded i guess. Thanks.

I know you weren't bro. I was just explaining how with a lot of apps this issue can happen relatively easy. You just gotta try and figure out which app is causing this and then I'm sure you won't have an issue anymore.
go to settings>about>battery use to see which app is using more of the battery.
you can also check to make sure your wifi sleeps when your tablet is off.
I am using task rom also and I don't have any battery issues. Before I go to bed, I always turn wifi off and kill all the apps thats running in the background and my battery never drains more then 3%. I hope this helps.
ot: how long does it take to fully charge the Galaxy Tab? i charged my gt for the first time yesterday and i wondered it took half of the day to reach the 100 percent
Thanks for the tips.
For the official charger that gets bundled i can usually charge fully in what feels like 3 hours.
Via USB on the non official it feels like i need 6 hours

Is there a difference between wifi sleep and OFF? I know there are some market apps that turn the wifi off based on certain conditions but i don't know if that saves more than wifi sleep
I put my tab in "Airplane Mode" when I sleep, and kill all active applications. I found this usually drops 1% or so when sleeping for 8 hours. The airplane mode shuts off all radios.
I have a button on my home screen that toggles the airplane mode, so I just tap that before hitting the power button.
This thread is very useful. I have been noticing a lot of battery drain while the Tab is in sleep mode. Changing the WIFI setting so it was turned off when the Tab screen is off made a big difference.
When I check the battery use info, one of the biggest power users is something called "Mediaserver". Does anyone know what this is. I am not sure if this is something running in the background or just displays as a result of viewing a video recently. If it is a background app, can it be safely disabled? Should it be disabled?
BTW, for those of us who are using Task's ROM, it is really easy to enter airplane mode. Just press the power button to bring up a dialogue box that allows various options including Airplane mode, reboot, recover, etc. This is a very useful feature.
Razr MAXX running ICS leak
I decided to let my battery run down to zero last night and let it charge while I sleep. I got to work this morning and just notice my battery is at 50%! The only change I really made yesterday was re-enabling smart actions, and setting a wifi connected trigger to turn data off. I'm thinking this may be the cause of the drain. Here are some screens.

I have no clue what "deleted_wake_locks" is. All my google results seem to point to wifi usage, and am thinking there is an issue with Smart Actions and Wifi might be the culprits.

There is an app that is not letting your wifi sleep.
Something is keeping your wifi on all the time and eating up your battery. Check out this app in the market and report back with the results, it's called "My Data Manager" and it will tell you which app or process is eating up all your wifi. Let me know what it says.

This might be helpful as well, this guy changed the DTIM interval on his router and it fixed his issue.

I've found on the stock rom, the Verizon wifi control app works well for turning wifi on and off by cellular location, ive heard tasker does this well also. Ive had no luck with smart actions. You also might want to go to settings, wireless, wifi settings, hit menu, then advanced settings, then change the sleep policy, if you have root you could also change the scan interval by editing the build.prop or using rom tool box. But do kill the wake lock, it not only keeps the wifi from sleeping, it also keeps your phone from going into its low power state

I am having a similar problem with my Razr (not MAXX). Just today i noticed the phone getting hot in my pocket. I then saw the battery was almost dead after only 4 hours unplugged and very little use. I recently rooted and flashed the clutch extreme version. I dont use wifi. I have autokilled everything useless, ive checked the running apps and nothing wierd seems to be running, in the battery usuage, after 4 hours unplugged "google services" and "android os" both had 33% of the battery use. But like i said i cant see what is draning it...any ideas?
Thanks in advance.
Even im having some issue there's a process called Media which always is 92% and eats lot of battery.....so is there any way to kill this process?
If your phone is rooted my advice is to use ti backup and freeze the bloat ware the list of pre installed apps safe to freeze/uninstall can be found in the forum, when your phone reports "android os" "system" "media" its a general term that covers built in apps. The major culprit ive found is Verizon's back up apps, media is probably motocast, try mulling around in the settings and set the sync settings to as minimal as possible, also if you guys don't mind, I'm curious about this, when i first had batt life problems i ran voodoo ota and disabled root and forgot to re-enable root, with bloat and all i seemed to have better bat life, anyone want to test and see if its the same for them? Wondering if Verizon is being sneaky, and pulling carrier iq -esqe info from rooted stock

Never let your battery go down to zero. That is very bad for lithium batteries.
ok guys i found solution to media process.....Android media was trying to update it's music player and galery and since there were some media files which were too big in size and seems other files were corrupt so Media was trying to read them and thus eating up lot of clock cycles and thus draining battery. So once you identify which media file is causing the problem then media process get's minimal. About android OS process there's nothing we can do except to freeze some bloat.
Another way to disable media, though you have to do it every time you reboot, is to kill the process in running process in settings then applications. Mine does the same thing.

I was under the impression that the android os has a safety built in that keeps you from actually reaching 0, and the process of draining your phone until it shuts off, wiping battery stats in recovery, and charging too full while shut down was more to retrain the os to see 100% at a closer point to full and 0% at a lower safe point of shutdown... i know flashing roms not at 100% battery can muck up the scale, a good indicator is that your phone shuts off from low battery, you reboot and it reports a something like 20-30% battery

I would assume this is true for all android devices but at least for Razr I can assure you that it will turn off the phone before the battery gets below the critical voltage. That said it is almost always better to recharge well before it gets that low and as much as it is possible charge to full. I almost always charge over night.
Has anyone noticed significant battery drain whilst the screen is off, my phone loses around 1-3 % every hour even when there are no programs running. I have monitored the running apps and uninstalled many that were running in the background. Does this mean that the 5th core is not activating or am I doing something wrong, google now, wifi, bluetooth, 3g, etc are all turned off, If anyone experiences similar issues or knows a solution please post, other than that the battery life on this device is actually pretty good despite all the people stating how horrible and unsatisfactory it may be.
I believe someone mentioned that the WiFi is the cause of the drain while the phone is on, is your WiFi on while it's sleeping?

Google Now may cause battery drain while on standby, I think. You might want to install Better Battery Stats so you'll know what's eating up your battery while the phone is in sleep mode.
My WiFi, Bluetooth and 3g are all turned off and Google now has been disabled, don't know what is causing the drain but the people over at the original one X forum are sating that standby drain is higher as of the jb update which I find odd seeing that the battery life is better screen on.
Turn off auto sync & just enable it when you need to, or use an app that will enable it for you after a certain time period.

Nah I can go a day and half on stand by with little use. I have 30+ apps installed and mods to firmware plus nik3r's custom elite kernel.
I'd say its one of your obscure apps you still have I stalled. Do a factory reset on your phone and install each app one at a time each hr monitoring the drain till you find the culprit.
Install nik3r's kernel.

1) go to Facebook app, disable chat, disable location... disable auto updates/notifications too if you can. This crap (especially the latest version) can take 20% of your battery life easily.
2) go to Google Maps settings, disable all the tracking/reporting options out there (up to 15% battery life without ever even starting the map app)
3) install EliteKernel and use power saving if you need that extra standby juice (it actually saves power in my flavor compared to the stock version)
There - fixed.
Wifi is not the issue, I get better life on 100% wifi than on data connection. It's the apps that actually use tha data.
Thanks guys much better now!
turn off this, do not use that.....
if is this the solution what is this? a phone or what?
only hope a room that end with this battery drain, is not normal that my wife S3, the same battery (2100mA) like hox+ has more hours, and not only 1 or 2, 6 hours more battery life, both without use.... in the same place, we did it as a test and..... that´s the Q, why? we have the same apps installed, and we have the same on, wifi, data, gps, blutooth..... the same conditions
First and foremost I'm stock rooted and unlocked (bootloader). Got an Anker 6200 mah battery and recently cycled it for the first time with great results. Used the app battery calibration to wipe stats after charging to 100%. Unplugged the phone and turned on the tether. Noticed it went from 100% to 80% ridiculously fast. Opened up betterbatterystats and realized I had some wlan wakelocks and the top offender was mdm_hsic_mp0 kernel wakelock.
I've found a FEW references to this but not many and still not sure what exactly it is. Nothing unusual pops up in the dump log file. Sure I have a few sync partial wakes but nothing over 4 to 5 seconds. This mdm_hsic_mp0 has been kernel wakelocking for 2 hours. Now, I did turn on my hotspot tether during that time, but strange I never noticed this wakelock prior to this seemingly increased battery drain.
So my question to you all is, what is this wakelock. I've disabled almost all my syncs, no location services on, etc. Trying to eliminate every possible source and build my way back up.
I hate wakelocks about as much as I hate politicians.
Thanks for any help you can give me.
Okay left the phone on the charger all night and got her back up to 100%. Now checking BBS this mdm_hsic_pm0 wakelock is still happening. I have not used tether/hotspot what so ever and wifi is off. However I have noticed that when I go to the stock battery stats screen w/in android settings it appears my data is shutting off. Almost like a fast dormancy is taking place to conserve battery. I didn't think Verizon supported fast dormancy. But I do not see any references of "fast dormancy" in BBS.
Any ideas?
I used to have that issue on an old version of cleanrom... I turned off multi windows and that seemed to help it... Not sure if that is it though... Could be a coincidence

Thank you for your input.
Installed Beans build 8 and have it (the wakelock) but I've got it figured out and now it's not wakelocking when nothing is going on. Prior to flashing Beans rom however it was still wakelocking w/out what I think is the cause.
It's for the verizon mobile hotspot app. I timed how long I had it on and roughly was the same amount of time that the wakelock was occuring. Phone has no problems going into deep sleep as it's been in deep sleep for 9 hours on this cycle. So I'm content w/ what's happening now.
Hi guys, I don't know what's going on, but my phone's battery has just turned to crap recently. Today, I left for work at 7 with a fully charged battery, and hardly used it aside from a few texts. By noon it was dead in my pocket out of nowhere (my battery saver mode never came on any of the times I did check a text). After that, I threw in my second battery at 12:30. After browsing on my phone to 87% on my lunch break, I started checking on my battery from there:
Within a half hour, my battery life went down 7% to 80%.
Another half hour passed, and it was down to 77%
After another half hour, 74%
By 4:12 PM, my phone was at 68%
54% at 4:45 after reading and replying to one email
Looking in GSAM, I see that 57% of my battery is used by apps, with Android System taking up 18%. OS Services is also my highest data use today, at 16.9 MB. Screen wake is only 1%, so it isn't a wakelock issue. I have sync, bluetooth, wifi, and NFC turned completely off, and am on LTE throughout my work day, with a good connection.
Strangely, even though my phone is in my pocket for most of the day and GSAM says Android System is #1, the built-in battery usage setting shows Screen as #1, followed by Android System, then Android OS.
I'm honestly at a loss right now. I can't think of anything new that I've downloaded. My phone usually makes it through an 8 hour shift fine and then some; the thing has pretty darn good screen off life normally. Please help me figure this out!
I think, because it happens to me at work, that is something related to marshmallow amd wifi, Try to go in the advanced wifi settings and select only when connected under the second option in the menu, Then See if it is better.
Another person that works with me has the problem with his s7 edge so i thougth that it could be related to the wifi bug of marshmallow

I always disable it because google services is calling it a lot of times (I know that it's for "lost my phone" feature and so, but still disabling it anyway)
Yeah, battery is bad. I have to G5 for a week. Its a great device but tge battery sucks.

Try turning off Always on Display. That batters battery life.
I get a full day, minimum 4 hours SOT at 75-100% battery.
Fingerprint also wastes battery.
