FF02 Battery life? - Samsung Epic 4G Touch

I'm getting horrible battery life. Did a clean flash of ff02 right after it was leaked. 100% to 4% in 4hrs25mins. Anybody else getting this? I use it pretty heavily but it's still under 3hrs screen on with brightness at minimum.

Using data uses a lot of battery too. How much data were you using when this happened? If you turn airplane mode on you'll likely get 6 hours of screen time.
Also, try removing bloatware. There's like 6 sns apps running in the background.

You don't by chance use the official Facebook app do you? That can get into a state where it will never allow the phone to sleep and will be constantly using %25 cpu.

which ones did you remove?

ko's tweaks
not sure what rom ur running..but if its compatible with kobridge's batt tweaks, u should def check it out. I jumped on ff02 on venum's boa rom with the sf tweak and battery life is awweessooome!! and super fast!

Airplane mode would defeat the purpose of having a phone wouldn't it. I do use the Facebook app. I uninstalled it and will see if that helps.

Alternatively, just hold down the home button and swipe it closed after you're done with it each time.

All of them. I don't use Facebook or hardly anything that syncs often but removing sns apps made my battery better. Unsure of what appd to uninstall? Flash Calks bare from converter.

Turns out it was a bad battery. I'm now getting close to 10hrs total with 4hrs screen on time

Did sprint replace it or did you buy a new one?

I'm always seeing horrific battery life, very disappointing.

I bought an oem battery from eBay

Not bad. What was your actual screen on time?
Can't post screenshots right now,but I am getting stellar battery life with FC15 and FC07 kernel. 5 and a half hours on battery,down to 65%. Been streaming music and using GPS this morning too.

Yup, not bad at all. I definitely notice this phone drains slower during actual use than my precious 2 phones.
Fc15 seems pretty stable and comparable to GB on battery life. Keep in mind calk automatically wipes battery stats during install, so it will take a couple of cycles for the battery meter to be reliable again. I wouldn't be surprised if fc15 is the official ota. I am having wifi constantly restart, but I am pretty sure it is my college's wifi security and not the ROM.

Here's mine today after the first full charge since flashing. Mostly Tapatalk cruising the forums though. Pretty respectable, but in line with my particular usage pattern.

Agreed. I ask currently trying to get five charge cycles and screenshots completed. Will pay up at the end of it.

Any idea why this happens? Also phones keep restarting
Sent from my GT-I8150 using xda premium
I don't have a clear idea but I assume that the battery counter on your phone is wrong in comparison to the actual battery % so what I did was turn off my phone and remove the battery for a few seconds and then put it back in and turn on my phone, it usually shows that my battery is lower than what the counter said.
So you mean I have to re calibrate my battery?

I pull my battery out and leave it for a few seconds but first off I actually think its the ROM and not you, PaanoidAndroid for our phone drains quicker than CM9 so its expected also is this on standby or playing games and stuff?

Its probably the ROM your using that's causing the big battery drain.

I was using stock ROM until about 2 weeks ago. Then I installed CM9 and I noticed a huge difference in battery life. I tried ParanoidAndroid today and it's the same story here. I'd suppose that since it's based on CM9 it has the same flaws.
I read though, that some guys are using CWM patches to "improve" battery life. Worth looking into, if you're not considering going back to stock ROM.
Yeah... After a few days ago i'am using stock rom. And I got better battery life, rooted no cwm, voltage control & juice defender. I have about 12-16 hours.
Compare with custom rom before, I never get more than 10 hours battery life.
But stock rom have less animation than custom rom.

What is your screen on time? If it's 4 or more hours then this is normal.
I'm not worried about that and this is new the media server.

If you stream music, or listen to music in the background while using other apps, that could be it. Surprisingly low battery life, I get mostly 12 hours with heavy use on full brightness.

Wow really? Do you think my battery is faulty? That's actually average battery life for me moderate use. At 50 brightness

Sent from my SGH-T999 using Tapatalk 2
The fact that depletion is seemingly almost as fast as charging, I'll call a faulty battery. But your screen-on time is rather long at times, so that might lead to it. Try setting the brightness to automatic for a day, and see if that helps at all.
Post your screen on time and how long you were listening to music and stuff. Was it streamed or was it off your sdcard? Are you in a poor signal area or descent? Your awake bar shows you use your phone a lot or you have wake locks. Give us a little more info before you return the phone/battery.

Need more info, my guess is a background app. Looks like you are stock 100%? That's your problem, lol... Just messing. What is your screen time? Click on display to see that... You're in a 4g area so signal shouldn't be the culprit. Your media is #1 user, but why, were you using it?
More like an hour and a half close to 2..if you used it for like 20 to 25 minutes I would think it's common. Like dude said above me we need screen time, also data technically eats battery away faster than wifi just a thought. Brightness is important too maybe you can try power saving mode, don't expect much difference though. Darker wallpaper helps, but most importantly are you auto syncing and if so which apps it usually starts there. Every little bit helps, most powerful phones have average battery life. Unless you start undervolting voltages and cpu that's where you see the big difference.

Has to be a rogue app. Try wiping the phone and reinstall everything with increments to get to the root of your problem.

Media server battery drain issue

I have searched a few times for a resolution to this problem, but have been unable to find one that works. I have noticed that when the media server shows up under my battery stats screen I usually have an update waiting on play store.
Is there any way play store could be the cause?
In other posts I see people complaining of 10-20% battery consumption. Mine has hit up to ~70% battery consumption.

Turn your data off when you're not using it. But most likely it's an app causing a wakelock.

Ok this may be a dead question, but something I would like to add. For the past two days I have not seen the media server in my battery stats. This is a shot of what I saw this evening. Which this is what I think my battery page should look like. I have not made any changes that would explain why it's not showing up. Any ideas or comments appreciated.

Not today, not sure about yesterday. This is not the only time it has not shown up for a few days. I also have not had any app updates. I think it's like bilgerryan stated that something is causing a wake lock but I close out apps when I finish. And usually use avg task killer to kill most running tasks.
