Cdma tab cm9 battery drain while off - Galaxy Tab Q&A, Help & Troubleshooting

While running the latest cm9, does anybodies battery drain while the cdma galaxy tab is off?
Sent from my SPH-D700 using Tapatalk 2

On my galaxy tab, since I flashed cm9, battery goes down too fast... With stock Gingerbread, battery survived for one week, now only one day and half... I'm a little confused...

Install CPU spy from Google play store and monitor your CPU to see if it entering deep sleep or not.

I did... And my tab didn't enter in deep sleep.. Only in 100 Mhz... Or 800 Mhz when I played...

Install better battery stats.

none of these custom ROM are optimized for battery.. i have tried a couple of them..
you can give 'Easy battery saver' from google play a shot.. it is a good tool and can help you in optimizing the battery..
BTW what do you primarily use your phone for?

Not 5% for that short period of time.
Something is seriously wrong dude, download betterbatterystats and run it a bit and see what drains so much. Either your battery is bad or you have some app that drains a lot battery in background.
Can someone please guide me on how to use betterbatterystats?? I installed it but I don't know how to make it work :s

Go uninstall facebook.
it made my incredible S last like, 3 hours longer
and my nexus 7 battery life went from 3 days to 4 days
3.5 hours of screen on time is a lot, id say at almost lasting a whole day you're doing pretty well?

Galaxy s random power off...

Hi has anyone heard of the galaxy s turning itself off now and again, for example i put it on charge then two mins later theres no reaction from buttons i press, have to take battery out then power on. It happens when i leave it for a while, not just on charge...
Thanks
Sent from my GT-I9000 using xda app-developers app
I think it could be the battery not holding its charge or something to do with battery. It happened since i updated to fishears 10.1 latest

Ah! Problem fixed, it was apparently called Sleep of Death and fixed by changing cpu gov. And I/0 scheduler.
Thanks guys!!!

Battery drain

I'm having a problem with my phone not going into deep sleep, I've tried reboots and stopping background processes, it didn't help. Any ideas?

Try betterbatterystats from store then see what's actually happening behind the scenes.

Why are you complaining? You got more than 17 hours from only 35% battery loss! I get maybe 15 hours with 100% battery loss -_-
But to help your problem, install an app called greenify. It allows you to block certain apps from being active in the background.
I usually lose about 5% tho after 12 hours with everything off

I'm getting 25% drain after about 9 hours of deep sleep on the newest Slimbeaan 4.1 release. I seem to remember only having 5-10% drain overnight on the first few builds. Is my battery dying or is it the newer builds?

Are you sure you mean 4.1 or 4.2 which has recently been released? The battery drain on 4.2 ROMs is an issue right now, although 4.1 isn't a whole lot better either.

I switched onto the 4.2 bandwagon a while ago and just recently reverted back to Slimbean 4.1 as I had remembered having great battery life on it. But after flashing and using for a few days, it's really not that much better. I still lose about 20-25% overnight on both 4.2 and 4.1 on the stock battery.
Well I just noticed something, it clearly says 17 hours, I assume on a 1+ year old battery am I correct? If so, then why are you complaining!!! Lmao you have Fantastic battery life!!!!

17 hours?
I'd be interested to know what ROM, etc. the OP is using to get 17+ hours of battery life out of this phone. Is it an extended battery? I'm getting pretty poor batter life after recently switching from Peach to Slimbean 4.1.2. Greenify seems to help.

If you have noticed, most people with good battery life seem not to use the phone to make calls. I think searching for a network drains the battery

Battery problem.

My phone is consuming too much battery power.
I will give you picture and tell me if this consumption is normal if not tell me why am I getting this awkward battery problem.
Sent from my GT-I8190 using xda app-developers app
I think thats normal since you surf the net much or you can try read the thread at the galaxy SIII mini general forum about the latest kernel for better battery life.

Try benz rom. It has good battery life and performance.

You can give it a try to a new rom if you have rooted your device, if you haven't you can install juicedefender from google play to optimize your battery life and optimize your time while surfing the web with chrome.

Awesome battery now!!

I have awesome battery now after trying many roms. I'm using rextreme 4.3 stable with megabass audio driver and boeffla kernel. I'm using boeffla config to set it to 500 mhz touch boost, all loggers off, -75mv cpu, 160/266 gpu with -15mv.
In setcpu I've set 1200 to maximum and using smartass v2. These are the settings on setcpu and what battery life I get with using YouTube for 2 hours, a bit of hspa+ and the rest Internet browsing. The phone only gets hot occasionally and my battery is 2 years old. Soon I will get a 7500 mah battery which will be great!
