at this point we don't know what ROM/kernel zakkkkk is using, so droidzone's may not even be compatible.
calibrating does not increase battery life, just might stop if from shutting down suddenly at a higher than normal percentage.

so what rom/kernel combination are you running at the moment, did this occur after flashing something/installing an app?
in the battery usage, is it shown as awake during this time? i would check using something like betterbatterystats to see if anything is accidentally keeping it awake.
if there is still a problem, make a nandroid and do clean install of your ROM or 2.3.3 RUU without installing anything else, see if the problem still persists. may then be hardware.
(can't remember exactly, but i think the dialer issue could have been a gb sense error, which reported it much higher than it actually was actually using. i remember clicking the dialer battery use and seeing the actual cpu usage and runtime was minimal)

im using droidzones supernova rom and have been using it for about 6 months now. my battery life has been excellent. this problem only occurred today. i installed a few apps/games over the weekend but i dont know which one is causing this. i have also tried uninstalling a few but with no affect. are the any apps in the market that show which apps are draining battery?

sounds like you've partially answered your own question...
if you were having excellent battery life, then suddenly went bad after installing something, then this is the likely cause...

i think you can download it for free on xda on dev's thread.

can you please send a link for the batterystats apk please?

[Q] DARTHSTALKER v8 Battery life

What's your "Screen on" time? I usually get 30-36 hours using stock kernel on V8. Have you cleared cache/dalvik? Also, check to see if you have any runaway processes by going to Settings > Battery and seeing what's eating up your battery power.

You can always try another kernel also. I run faux's kernel and I love it.

This is my battery life on the ROM

Is it better on other roms? If not, maybe bad batter, but if so, first you need to start fresh with this rom and wipe everything and start over. It should not lose 12% with only 4 minutes of on screen time.

Here's my battery stats as of today. Mind you, my ROM is really debloated.

Battery drain on 4.2.2 Roms

Hey guys, I have a terrible problem here. The problem is that I got tired of Sense and I love stock android 4.2 and I just cannot use roms built on that android version because the battery drain is humongous. Using my phone just to check twitter and facebook and it goes down in 3 hours. I tried Cyannogen Mod and I'm now on Icecoldjelly both with Xm kernel and it is always the same. This is terribly annoying because the roms are perfect and so is the phone, except for that battery. Does anybody recommend I do something, are there some mods/tweaks to increase battery life? Is I cleared battery stats and performed more than 3 charge cycles, in case you ask. Thank you, hope you can help me

haha! and I thought I was the only one... I see people who are getting 15-18 hours on ICJ...
I also get terribly low battery backup... even though battery is calibrated.. Sync off... Auto Brightness.. etc etc...
However, on sense roms I get great battery!

I would suggest a faulty battery, I use mine for twit and fb too and a whole load of other stuff but i get a lot more than 3 hours. I am on slimbean 4.2 now but I have tried cyanogen 10.1 and icj, both of which gave me similar battery life to slim, although neither of them could equal slimbean they were not as bad as you are experiencing

But the battery is fine in sense roms so that is a bit hard to believe. This is really crazy, in 4 hours today it got to 25%, one of those hours being in standby. I'll try some other roms

The reply wasn't intended to get you to try slim, only to show that not all 4.2 roms are as heavy on battery. there are plenty of others to try, I just prefer slim

I get around this much:

Not that bad... Not good either! :/

I'd say thats about normal, but the op's 3 hours is seriously wrong. I would have to use navigation, music, facebook, twitter and XDA all at the same time to run my battery down that fast

With minimal usage I got around 5/6 hours. I'm going to try other roms and settings to see if I get this right. I'm currently on slim. I'll see how it performs tomorrow. If it goes bad then wth, I'll just go back to a Sense rom

Disable auto sync/fb location... use trickster mod and set governor to smartmax and IO scheduler to row/sio...
Cap the max frequency to 1.2 GHz... Use greenify to hibernate apps which you don;t need..
There is absolutely no lag for me... When I want to play some games I just switch to interactive or gaming governor!

Thanks everybody, I found my daily driver, today I got 13 hours with regular usage and still 25% to go, slimbean is the best. Even if it was not a recommendation to test the rom, it helped a lot

4.4.2 Battery drain

I've tried a couple kitkat roms for my note 2 and the battery drains at 15-20% an hour with no activity. It's also slow to charge.
Is this common with 4.4.2? Should I stick with 4.3 for the time being?

Trying and using are a lil different.[emoji48]
Trying we flash it (Rom) then if it's not acting right we flash something else...
Using is when you AT least let the Rom settle into your phone/device. A day or two should be good enough to know what's doing what...
Check this app out if you don't have it yet»» http://goo.gl/vffD4d
In order to compare battery stats...
Another thing is your kernel and your setting that affect your battery life...

Bajanman is dead on. Gotta let the ROM settle.
However, in the meantime, check your Location settings. In "Mode" take it off "High Accuracy" and change to "Battery Saving"
This was draining my 4.4.2 ROM'd Note 2 badly.

I always get great battery life with my note 2 on 4.4.2 roms.

[Q] About battery life, compared to GS2

I would like to know, no ROM specific, how is battery life in general, compared to GS2 i9100. Ive been thinking on getting an S2 plus but I recently read that battery life is worse than the original S2, and I would love to hear some opinions.
Thanks!
Enviado desde mi GT-I9100 mediante Tapatalk

Well the S2 is quite old, so no matter what variant you use don't expect to much from the battery. Also since our devices are old, and many using different Roms, kernels, and varying other things. Comparing battery life is going to be difficult to do. I have the Hercules variant running cm 11 (4.4.4). Battery life is typically around 8-10 hours of usage and 13+ hours of nonusage.

Just installed fresh 4.1.2 stock on my S2...rooted and debloated a LOT.
First full charge I got 1 day 9 hours with 4 hours screen time.
Do note 13 of those 33 total hours was on airplane mode.
Still, nothing beats stock if setup right. Location(gps) off of course.
And only used tapatalk and browser mostly.
And the 20 hours NOT on airplane mode was on WiFi. (No sim card)
