GT-P7500 - Is there anyway to fix JellyBean battery drain without rooting? - Galaxy Tab 10.1 General

I have a P7500 that my work gave me and recently I updated it and now the battery doesnt last me 12 hours and I need it to last me for work.
Im all for rooting it but since it is not my tablet I cant. Is there anyway to fix the battery drain without rooting?

It helps for sure to pinpoint the leechers on your device and maybe you're able to squeeze a few more minutes out of your battery without a custom kernel.

better battery on stock non-rooted

hey guys i have looked around and searched but i cant seem to find what im looking for, my atrix battery last literally 3 hours with about 10 min of craigslist, 10-20 min of game and rest for texting, that cannot be normal. so my question is are there any ways to fix the battery life on 2.3.4 stock with no root? or is my phone defective since my battery life is so bad.....? thx
Need more details like rom, kernel, phone version, how old phone/battery is. Also, for starters charge phone fully and then run down battery to 5% and charge fully again, and run down low again and charge fully again. This should calibrate battery. If nothing improves then it could be rom, app, kernel that is screwing with you. In the unlikiely event trying all these solutions doesn't help, your battery might be fried and not holding charges well, or you have a hardware probelm that sucks up juice.
I voided my warranty and your mum.
everything is completely stock i just updated it from 2.1 i think, thinking it would help but no. i updated it thru the phone to 2.3.4. the phone apparently is only 1 week old.

Battery life decreasing...

Ok, so I've had my SGN for little under a month for the first few weeks I had it I was getting great battery life, almost 6 hours screen time full day of battery etc.. Then I rooted it using one click root because I wanted some more access, since then battery life has seemingly been slowly getting worse. I have tried changing back to stock roms and custom roms, I've fully discharged the battery and charged while it is off a number of times but I'm down to 3 hours screen time and can't get a full day out off it anymore.
Is this something to do with the way I rooted, what can I do test and try and get back my battery life, this is the main reason I got this phone..
It's hard to say if it was the first update I installed/rooting or something wrong with the way I'm charging but it's certainly decreased even on a stock ROM without installing anything..
Anybody else encountered this?
Check battery stats and show us a print screen

Going to try latest firmware and just bought Odin mobile.. Hoping that'll fix it.
Won't let me add a picture says I don't have permission.. Sigh.

I have the same "feeling" with my Note. I have installed System Panel to monitor usage but I can't find anything specific that seems to be sucking the power. But it certainly "feels" like my battery is draining faster than before.
It's probably as the phone gets older, you install more & more Apps. Some of these are probably working in the background sucking your battery.

Even with a clean stock rom, it doesn't seem as good as it was without root or any updates.. Wish I remembered what the phone came loaded with, I'd give that a go..

Try Rocket Rom v17 or latest XXLA1 firmware and your battery life will come back even better than before, just me
Same "feeling" here! I will try LA1 firmware....
So I'm currently sitting on 4.30 hours screen time, 15 hours uptime with 20% battery remaining.
Running la1 firmware and la3 modem, been using stock browser. Taking lots of photos with flash too, so I think this combo has rectified my issues but I know there's more potential as this is roughly the same stats I got on my dhd, although that was underclocked and tweaked to the clappers.
Faith is resetored in my device, hopefully it improves.

Battery drain

Hello!
I rooted my phone as of yesterday, I charged it all night and when I took it off today the battery went from completely full to dead withint 3 hours of no use. I did not use the phone at all.
Any ideas?
If you just rooted your phone, you should not have battery drain... Try to temporarily disable root (with Voodo OTA RootKeeper for exemple)
Use better battery stats to nail down which app is causing the drain
Did you try wiping your battery stats in CWM - advanced?
There's also an app, Battery Calibration, on the Play Store that may help with that.
Not uncommon to get weird battery readings after changing rom's or rooting.

+1 that app will tell you exactly what's bogging down your cpu, and which apps prevent proper deep sleep mode.

This is soooo strange. Not a normal behavior!! Before you root your phone, how the battery lifes goes??? Are you in a stock or modified ROM? Wich kernel are you using?
I faced this issue a couple weeks ago. Android S.O was the culprit and it was driving me crazy. I was using a custom ROM (RemICS-UX). I solved the problem returning to stock and erasing everything, then i reflashed the ROM and the kernel, in my case Devil3 0.79. If you want to give it a try!!
After that my batterys life is pretty fine, during at least 2 days!
Feel free to ask anything you want! Cheers mate

Go through a couple more full charge cycles, if android os usage isn't very high then, it should be fine.
Edit: on second thought, draining the battery without use in 3 hours is extreme, and would suggest that the CPU is running at max speed all the time. If it doesn't solve itself or improve a lot after a few more charge cycles, reflash everything.

Did you just root your phone or did you flash another ROM? Some ROMs have horrible battery life.
The stock battery usage monitor (Settings>Battery) should be enough to tell you what ate your battery. If it's a particular app you're running, try disabling that and see if it improves. If the usage is mostly "Android System", "Mobile standby", or something like that, then you have a tougher problem. The free app CPU spy will let you know if something is keeping your CPU usage high. Better battery stats is pretty cheap and will give you much more specific information.
+1s for BetterBatteryStats and waiting a few charge cycles before judging/debugging your battery drain, especially if you changed your kernel to root or flashed a rom.
I find that after flashing a new rom or kernel my phone, the battery level shown in recovery mode is higher than in the rom's settings, for a couple days. (You can see batt level in semaphore's recovery). I once dud a lazy search about this and found nothing, but I figure that's what is meant about waiting a few cycles gir your battery to calibrate.

There's no such thing as "calibrating your battery". It's a myth. Wiping your battery stats file doesn't do anything other than reset the tracking of what's using power. It doesn't magically fix your battery meter. Flashing a new ROM doesn't leave left over data, again a myth.
Battery life is never consistent after flashing because your ROM needs to "settle" for a day or two first and during that time your ram and cpu usage are all over the place.
The rest is a placebo effect.

I think I may know what is happening to you as of now. Try to bring up the Battery settings if you are on ICS and take a screenshot and post it here. If my 'spider' senses are correct, your phone did not go to 'sleep' and remained awake.
Since I can't put my signature for unknown reasons...(Maybe because I just created an account since I did not want my old one)

Currently I'm experiencing a huge battery drain too. I used both tools which where mentioned here in this thread and when the drain occours, CPU spy reports that my SGS didnt go in deep sleep at all with turned off display, it was at least at 100mhz all the time! I attached 2 logs from better battery stats and it seems like the NotificationService is causing it?
I'm using JW6 PDA JW4 Modem and JVC CSC in combination with the MNGB 0.5.8 Kernel.
Definitely, now you got to find out what is causing it!

CM 12.1 battery drain problem

Somedays ago, i use CM12.1 10xx build and experience a battery problem, i though it was only me who had this problem.
But guess what, it's actaully from CM build problem.
And after the days, people says that they fix it which having a 6 hours of SOT and AMAZING things.
ANd right now i am suing 10192015 build which still suffering Battery Drain.
I mean, 44% for 1h and 15min.
I was like WTF?
So, guys, please, help me out, gimme ur review on CM12.1 that have the most stabil battery life.
Otherwise, i should go back to Cloudy ROM again which giving me 5h of SOT. :/
I use this phone for works, so of course battery life is damn important for me. :silly:
The only reason that i switch from Cloudy to CM is rotation got some bug. But that's another story.
anyway, dont forget to answer my question.
A clean flash of cm12.1 may resolve the battery issue.
I'm using Inazuma 2.8c and the battery life seems to be quite good, although I am not a heavy user.
A clean flash does not solve anything because i already did.
Anyway, i appreciate ur reply.
i have the same problem on note 4 with zero lemon10,000 battery. Let me know if you find a answer
Try going into privacy guard and setting location to ignored or always off (I did this to the built in apps as well).
Where is privacy guard?

S7 Edge Battery Life after root is worse, due to Kernel / CPU usage?

So just before I continue this I want to say that I have Trickster installed and have done all the tips and fixes for root on the phone, and I notice that my battery drains pretty fast when in use.
I just was curious if it's cause of the Verizon version I'm on (before PE1) would anyone be able to tell me their battery life after root and give me any tips other than the ones already posted?
And please if you require more info on my battery stats, please ask, and I'll give you guys whatever you need.
Thanks in Advance.

I went back to stock after having almost all the possible modifications to enhance battery life on root. One small tip is that if you flashed the V15 fix zip, you didn't need to change governor settings manually. Even so, no matter what I did, I could only get to about 3 hours of SOT by the end of the day even without GPS use and all that before the battery is drained. After restoring stock, I'm seeing my usual 4-5 SOT of daily usage.
I'd rather wait to see if root is improved without the high CPU usage because of eng boot, from what I was told. Good luck.
I too have noticed decreased battery life though I can offer no suggestions to fix. I just downloaded a CPU control app to play around with. Right now I am able to get through the day so thats all that really matters, but its definitely decreased from before root.
