Horrible Battery Life - T-Mobile Samsung Galaxy S II SGH-T989

So my battery life was, decent, I suppose for the most part until the other day it started going to hell. Idk if this was caused at all by the status bar battery mod I flashed, but even when I flashed back to stock it's still horrible. I charged my phone to 100% and let it sit on the charger for an hour just to make it was really full. Then I took it off and went to bed. I woke up 9 hours later and the battery was at 38%. It was on standby the entire night so idk why it drained so much. I looked at the battery stats and android systems took up around 40% and standby took up about 20%. On a day of normal use it goes from 100% to 80% in about 1.5 to 2 hours. I am rooted on stock rom but that's it. Like I said it use to be decent on battery life. Anyone have a suggestion? Should I call samgsung to see if I can get a replacement?

Go to recovery and clear cache and then go to advanced/wipe dalvik cache and then wipe battery stats and then try to fix permissions!

same problem here

Clearing the cache and everything definitely seems to have helped. Had decent battery life yesterday. Today I'm 2 and a half hours in and instead of being at 80% it's only dropped to 94%.

Battery Help

How well is the battery supposed to be while running the universe V1.4. All I get is about 5hrs with everything usually off. Is that normal. Should I get an extended battery? Can someone like me to one? Thanks.

While I cant speak for universe V1.4 that seems to be extremely poor battery life, i am currently on Blazer 4.1 GB, and with Wifi on, and moderate usage getting a whole day or more on a single charge.
have you wiped your batteries memory recently or just flashed the rom? it usually takes 4-5 full charges and discharges after a flash for the phone to re-learn the battery.
I would reset battery data in the recovery and then charge the phone to full and then fully discharge the battery, do this 4-5 times and see how your battery life is then.
Thanks but how am I supposed to reset my battery stats?
Edit:Nvm Got it.

besides going into recovery to wipe battery stats there is an app called battery calibatiion (market). does the same thing.

Battery script.

I need a script to reset my battery stats. I'm running cm10 a5. Battery is new flashed a few ROMs and now its funky. It super charges in a period of 20 mins it will charge damn near 60% and it will die just as fast.

Battery stats can be erased by simply fully charging it. Doesn't do anything really

what do you meant by "hard reset" Epic?
I think he means by hard reset that you need to go into recovery and do a complete factory wipe. That would erase everything.
Also, last night I was trying to download something with really bad reception. My battery dropped like 30 percent over an hour period. I was using the screen a fair bit. But, like a lot of phones, the battery life and bad reception are intertwined quite strongly.

Got it, thank you!
Signal levels aside, it takes a couple days before a newly flashed kernel/ROM/Update "settles in". Give it a couple days of normal use and then start looking at your battery life.

How much screen on time do you have? That's what really counts. Anything between 3-4 hours is good.
Im running stockmodrom and right now im at 50% with 14hrs and 1.5hrs screen on time.

Wow something's really messed up. Try clearing data and cache and force stopping the messaging app.
If that doesn't work then I guess a factory reset or flashing a new rom or kernel might.

Try greenify it will stop apps from waking up/running in the background, also you can freeze or uninstall stuff with titanium backup, and also monitor things with better battery stats app.
here is how greenify works, in case u never used it before.hope it helps.

Battery draining this fast while the phone isn't in use can only mean one thing: your phone is awake all the time. You had 1.5 hours of screen use but then, your phone was idle for the remaining time. I suggest you install BetterBatteryStats, it will show which process is preventing the phone from going into deep sleep (this is called a wakelock).

What's wrong with my phone?

So I have a zero lemon 9300mah battery and got the mean bean rom been almost a month that I charge my phone fully and in 2 hours it goes to 50% so I though it was the battery. I changed the battery to a new one still died fast than I thought it was my rom. So I changed that last night to liquid smooth and charged overnight. Woke up at 8.30 and now it's 11.00am I am at 33% from 100% what's going on please help me.

If your screen/display isn't the top thing then in most cases you have a problem
This is what mine looks like

This may sound silly, but do you ever turn your screen off, lol.
Just kidding, but that's pretty bad.
Click the screen on and see what your time is. Is that with the Zero Lemon?

Either a CPU max run state...or a serious wake lock...or both..
Zero lemon getting drained like that is a serious problem...
I would suggest a "complete" wipe...and the flashing of a rooted stock rom as a test base...
If the device still exhibits the behavior...then a hardware issue may be at Work here...
If the device gets hot to the touch....then get the device to a stock and clean state...so some unmodified testing can take place...
Let us know...g

Even if you leave your screen on, never turn off zerolemon should still last you much longer than 4 hours of screen time. I have one, I get 3 days usage out of it
