FF02 Battery life?

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

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

I bought an oem battery from eBay

[TIPS] Lower Your Screen Power Consumption

Hello guys I wrote a guide that will help you improve your battery life because screen is the most thing that uses battery, here is a solution for all that, don't forget that the screen sensor for auto brightness is also taking lot of power.

I think we tested screen filter current draw on the nexus one and it showed no difference since its a software solution only. The mA draw remained unchanged using it or not.

Anybody noticed the difference, its doing great here.

This doesn't strain my eye as much, but doesn't see much on battery.
Sent from my Galaxy Nexus using xda app-developers app

I've been using screen filters for a long time now. Great app!

Sounds interesting, I guess, but lately I've been thinking my screen is actually more dim than I'd like it to be. To be honest, I wish auto-brightness settings erred on the side of "more bright" rather than "less bright." There's probably a mod for just that, but I haven't really looked for it yet.

I managed 4h30m screen time on auto brightness, data on.

My battery life time is pretty bad with CM9...
But when I tested that, my battery was already dead (not working well)
I've ordered a new one. Because my battery lasts only about 10 minutes. No joke !
You should probably get a new one, or don't use CM9...
Because this isn't normal. Others battery lasts about 1-2 days on CM9. (saw some screenshots in this forum, with cm9 and 2 days battery lifetime, without charging)
Try to turn of your Data connection (if you have one) or try to use WiFi instead of Data Connection if possible.
What about display brightness? Turn it down on about 50% to save power.
Hope I could help you a bit..

I think so aswell, because I had the same problem..

I'm using CM9 Beta 3 ,, And for me battery is much good
(But after Calibrating Battery and 3x full cycle charge)
Check this for battery calibrating https://play.google.com/store/apps/details?id=com.nema.batterycalibration&hl=en
And you may also check CPU Spy.. and see if your phone doesn't go to deep sleep : https://play.google.com/store/apps/details?id=com.bvalosek.cpuspy&hl=en

Deep sleep is a process qhen your phone processor is ''stand by mode'' so it doesn't consume too much battery but all the phone's apps are still working. That is deep sleep with my version. If anyone could add more or correct me please do
Pressing "Thanks" button will be much appreciated if user's posts useful for you

Got it. Thanks

I don't use my phone for long periods of time usually. Run cm10.1 and can get through a day and a half with typical use. This isn't a good representation but figured I post any ways. Just shy of 3 hrs screen on. Had to transfer some files to the computer hence the charging.

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.
