Has anybody else had trouble with rapid battery drain and Cell Standby being the process that's taken up most of the battery? I'm completely stock and unrooted at the moment

It's a known issue. They apparently added the wrong power draw amount when calculating the percentages so those are wrong but it's not really using more battery, just misreporting.

Any fixes out there?
You need to be rooted. http://forum.xda-developers.com/showthread.php?t=1732722

Do you know if this works only with a custom ROM or can I just use the non-Odin root method?

I used the non-odin route and just installed it on mine. Cell standby dropped from about 30% to only 3% after install.

So with that calculation being incorrect does that result in your battery life draining faster? I just got mine on 9/22 and battery is draining significantly due to cell standby (cell radio being at the top of the list) I heard through a friend that this will be fixed with jelly bean update?
Can anyone shed some light as I just switched over from iPhone 4 and this whole battery issue is disappointing, thanks!

Battery not draining faster. Percentage reported in stats is wrong. 30% shown is actually 3% and should be at bottom of list.

Thanks for the reply prdog..one more question cuz I just came back from the Verizon Store and they can give me a new one if I go back since I just got this on Saturday..
So the reported stats is wrong as you stated in Battery setting..so thats the reason why I see my battery level indicator draining? Because it does drain pretty fast.
I had battery saver installed and seemed to do great work but when uninstalled, my tablet's battery doesn't last more than 30 mins and it got much slower too. No virus was detected from CM though.

It can be due to many reasons. Firstly, there can be many heavy ram consuming apps running in background. Try to close them. Keep the brightness of screen low. Keep Wifi and Other data connections off when not needed. You can also turn off auto-rotation. This will increase your battery backup to a considerable amount.
Incase, it doesn't makes much of a difference, you should buy a new battery !

This isnt a battery save issue. When it reaches like 92% it instantly goes to 56 and at about 51% it goes like 15% or less, or it may even go from 54% instantly to zero. How can i possibly change battery? Its a tablet. How can i open it? If taken for service will they accept it? Its rooted.

I'm sorry. I didn't read your question properly.
Keeping in mind what you're saying, it seems like a "Failing Battery" . Tablet batteries can be changed but you will have to unroot first or the people at service center won't accept your device. So, unroot first and then go to service center.

Frankly speaking, No.I think you should get a new battery because a bad battery can be really-really dangerous !

Hello guys,
I have a problem with my new Galaxy S7. The battery is draining way too fast.. I'm constantly getting around 2 hours of SOT a day and the battery lasts about 12 hours... I'm desperate... I have tried everything from turning off Wi-Fi, Bluetooth, uninstalling apps to even factory resetting the phone. The problem is still there.. Please help me
BTW, my battery level is dropping 1% every 2-3 minutes

So after resetting it and without installing any app you still have 4-5% battery drain per hour on standby ?

No, I have 1% drain every 2 minutes when using the phone on light tasks( Internet, messaging, Facebook and email). Little to no battery drain is visible when not using the phone. But I can'tell get more than two hours of SOT on a full charge

I'll suggest you do something that worked for me, charge your phone to 100% and then restart it. Idk if it will work for you but tell me if you see any difference.

Facebook app is draining battery like that for me at the moment.
Uninstalled Facebook and it's still there... Nothing funky in battery stats apart from high usage on Android System
Update: just done another factory reset, the problem still persists

That's weird, try disabling everything you don't need like Bluetooth, NFC if you haven't already. Turn screen brightness lower, disable fast charging and "nearby device scanning", optimize the apps in settings/battery. Then do a restart and see if it makes any difference.
Hi mate,
I was in the same boat on Monday with a faulty device that overheating and kept freezing.
What I found was I had a weird bug, and 'Mediaserver' was constantly the biggest battery drain.
So saying that, when you go to your battery stats, what is your phone telling you is the main culprit?
Try this: charge your device to 100% restart it and then unplug the charger.

Yep, now I got about 4 hours of SOT (I did this once)

Hello,
The main battery consumer when looking at the battery stats is Android System.
Take a look at this
After a couple days of owning the S7, I checked battery usage of apps
OM Customise = 10%
KNOX = 10%
I've installed Package Disabler Pro, and disabled both the above, charging the phone now and will see if it makes any difference
If the above is true, that should give me 20% back by the end of the day

How much SOT did you have at that point?

I was at home all day yesterday, I barely used my phone. I unplugged it in the morning around 6:00am, and battery was reported at 100% until about 10:00am. That can't be accurate because I made a couple calls and browsed around a bit.
From 10:00am, it discharged slowly to about 60%, when I went to bed at 9:00pm.
When I woke up at 6:00am this morning, the phone was totally drained and off. This doesn't make sense. Standby drain should be 2 or 3% an hour. not 60% over 9 hours.
Something is up...I'd greatly appreciate if anyone can help me solve this.
The battery on this phone doesn't seem to be calibrated all that well, so it is dropping faster than it appears to be when you unplug with a full charge. It doesn't really stay at 100% for 4 hours, so eventually it will start dropping faster once the phone realizes you are missing more battery than it thought.
With that said, you definitely seem to have had some process that bugged out and was running all night until the battery died. If that keeps happening I'd do a factory reset

thanks. I appreciate the answer. Any idea how to find that bugged process? All of the battery stat apps require root to identify this, which doesn't exist at the moment.

I don't know how to yet on unrooted 8.0. I don't know if the keyboard is considered a system app, but I lost 20% of my battery yesterday to Gboard so I wonder if that's also your problem. Mine did show up somewhere in the battery stats though so if you didn't see it there that's probably not your issue
Try Better Battery Stats (there's a good xda thread) and gsam (from the play store). If unrooted, you have to set some things with adb to get all functions.

There is root now that is definitely some rouge apps and or un calibrated battery hope u get it sorted out
I don't have this phone (yet), but isn't there a way to boot into the stock recovery/bootloader and wipe the battery stats there? or maybe an app that can do it that does NOT require root?

Hi Nobody know ???
Why do you think that something is wrong here ??
You have 2 days of usage, with more than 5h SOT ...
Facebook apps are eating alot of battery too.

Thank you for your reply, I have the impression that the battery drains quickly, after charging it 100%. the percentage digits go down empty, is this normal?
(edit)
Even if you do not use the phone, its system is still running.
Many applications still run in the background if you haven't turned them off ...(settings - battery - app launch)
