somebody please tell me why is that? and how do i get more life out of my battery?

Maybe your phone only goes up to 9 hours...

Maybe it's kernel related.. Are you on custom rom already?

My Droid on a JB ROM has the Android OS consume about 90% of the battery and it dies after 8 hours of screen off time, airplane mode. *shrugs* if anyone has a solution id like to know.

This has probably to do with something that is running in the background.
your phone apparently doesnt go into "deep sleep mode" Only in this mode you lose just few % per night.
I recommand to shut off your phone, take out the battery for a few seconds, put it back in, charge it in one go, then turn it on again. See what happens.

You can, of course, sleep with the charger in.

Welcome to Android, for the most part, our battery life sort of sucks :/

Don't let your battery get below 10%?
The system is designed so that when the battery gets too low it turns off a lot of stuff so that the device will last for longer to do what it was actually made for - be a phone.

Indeed often the cpu is slowed down to which would cause lag.
But yes the best thing to stop it would be to keep your phone charged

Random battery drain. Please look at pictures

I have been running CleanRom 3.0 for about 7 months now and have been getting great battery life. For the last week or so I have been getting horrible battery life and i cannot figure out why. I have not done anything different or added any apps since the fall. I have done all the tips and tricks to saving battery ....display set at 10%/30 seconds, All notifications turned off, gps off, bluetooth off etc... I can usually get an average of 22 hours before needing to look for a charger.
Today:
10.5 hours and 12% left. Not even 2 hours of screen time. I have phone forced on 3g and get good reception at my home where I was for most of the day.
Can someone please give me some insight here? maybe I'm missing something??

Maybe your battery itself.
There are far to many variables that play a part in battery life.
Look into 5.6 and remember to toggle off data and WiFi when not in use.
Worth a try.
Edit: now I clearly see you toggle WiFi and data off when not in use. Haha sorry.

Agreed, try changing kernel or kernel settings, gov types, speeds, tweak options.
Sometimes it take alot of trial and error to figure out the best rom/kernel combos. May also have to change a few things in the rom and/or kernel to do so. Goodluck!

You can try an app call "Better Battery Stats"

Battery life on One SV

I have the Boost One SV (k2cl) and I've owned this phone for 3 weeks. I'm noticing battery here isn't so great. Well I've been testing some options out and I think I found a way to maximize battery life. I enable the power saver option and set everything to optimize power, then I enable the super saver option in Battery Doctor. Below is after almost 12 hours of heavy use.

What do you all do to optimize power?
EDIT: Woops didn't see the other battery thread but this is different in some ways lol.

Posted something about my battery handle in another thread, but here whats helping me for good battery life.
Note: It depends on everybodys location, situation and if he need some of this or not.
Basically i charge my phone every night, so i have the full power on the upcoming day.
I untick the options for Incoming calls:
Under Settings -> Mobile Data -> Network mode i usually don't let it switch between modes (most time i use GSM only and only switch manually to WCDMA if a network is available and i need it fast) cause always searching for "best network" is very power consuming. A low (or bad) mobile network can be one of the biggest battery eater.
I only switch Wifi on, if i'm in my Wifi network, cause it always search for any Wifi network, also if you are away.
And i only start bluetooth when i need and so on.

Battery life seems a lot better on ICS.

Mine is pretty good by changing cpu governor.

And how many screen on ? (most important) 4h for me

Screen on 2 hours in the morning and 3/4 after, MM is great with the battery, but i miss root access

i got between 2 and 4 hours depending on signal strength... for me there is no improvement in MM to LP.. but i think there can be if we could only limit the screentouch boost and/or the max frequencies of booth clusters

close pokemon go

Check out which apps are draining the most battery. Then select them to sleep via Greenify. Whenever you put your phone on standby, select the Greenify button shortcut instead of double tapping your screen to turn off. And use a normal charger instead of the fast charger that comes in the box, whenever possible. Only use your fast charger when urgency occurs.
