I got a question about the power consumption because I managed to reflash the phone 3 times ^^

1. First time I flashed both:
RX-51_2009SE_21.2011.38-1_PR_COMBINED_MR0_ARM.bin
RX-51_2009SE_10.2010.13-2.VANILLA_PR_EMMC_MR0_ARM.bin
to achieve condition as from the box. Then after a few days I realized that the power consumption was big enough: about 20% discharge over the nigt.

2. after some reserch of forums I decided to install CSSU testing, so after that the consumption of battery power normalised and the phone was able to work few days with normal usage.

The next thing was to install usbmode, but it requires kernel power. I don't know why, but kernel power v52 does not wanted to install on top of CSSU.

3.Therefore I re-flashed my phone again, installed kp52 and then CSSU. Straight after installed usbmode. Day later I noticed that power consumption became higher again..

And yes, I did all tests with closed keyboard and blank screen.
Now I am not sure, whether usbmode or kernel power itself eats the battery.
what about 1150 MHz frequency? is it kp52 settings or just lag?
