I'm getting more and more desperate, actually i've tried these combinations (xperia neo v)

Stock firmware 4.0.2.A.42 rooted, with:

* .283 kernel .42 baseband
* .283 kernel .283 baseband
* .283 kernel .64 baseband

Stock firmware 4.0.2.A.283, with:

* .283 kernel 283 baseband (ouviously)

Stock firmware 4.0.2.A.64 with:

* .283 kernel .64 baseband

None of these combinations worked for me..., i've switched the battery with my brother who has the same terminal (he doesn't have any problem at all, at 4.0.2.A.64 stock), and his battery in my terminal has drained like mad, however my battery in his doesn´t drained too much. I've tried a different charger...

Any solution? Thanks in advance, and sorry for my english!

Let it settle for couple days, after 3 or 4 charging and discharging it will be fine.

What rom do you use? And dont bloat your phone with any battery tweaks.

And give me a screenshot about your battery usage.

h tt p://i .imgur. com/ TNQAk.png (sorry i dont have 8 post even)

Display - 47%
Cell Standby - 17%
Phone idle - 13%
Music - 11%
Voice calls - 5%
Mediaserver - 3%
Wi-Fi - 2%
Android System - 2%

Battery remaining 22%

These are my stats, i've just back to 4.0.2.a.42, root and calibrated the battery with BatteryCalibrator. It seems it's during a few more. At leats the graph is better than before

edit: I've tested for about 24h and after calibration, none of these stats have changed. I will test 4.0.2.a.42 and 283 kernel more thoroughly.

I mean, charge and discharge for three or four times then see how it works.
BatteryCalibrator not even do anything to your battery.

I've been testing for 4 days but none of these solutions have solved my problem, i think i'll send it for technical support (it's still under warranty)...

If anyone have any suggestion before i send it, i would appreciate it so much...

Try turn off your bluetooth, wifi, and gps if you dont use it, and check your applications, maybe some apps eat your battery so much.

Or reflash your phone (dont restore your apps), then check wether it still drain or not.

I've done what you said before, no wifi nor bluetooth. I've make all the tests with all wiped and just flashed, and no results, 30% in about 8 hours, and battery is full drained in about 20h
