[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] sarf2k4:
Just wanted to drop off a simple comment and guide regarding the battery life and l2_hsic based on my observation and tests for some of these days.

l2_hsic been known to drain a lot of batteries for most people who are living in a poor coverage and for me, it can mow down my battery up to 50% in 8 hours with wi-fi on. The l2_hsic information is on the OP.

Last night I tried to change my network mode into GSM only and head to sleep, measured using the bbs with custom reference,for about 8 hours, only mows down 4% of my battery, from 66% to 62%, will provide bbs dump, although my bbs dump shows more battery usage, that's because I delayed the time to post this so it does shows that I used 15% battery.

I was wondering if there is an app/process made by any xda members to switch between GSM only and dual mode when the data mode active/deactivated? I don't have the resource if I were to create this process to hook into android system. This process from my theory, would've saved a lot of batteries when we disabled the data paired with GSM only mode.

:)

P.S:

I will continue to monitor if this really helps
