Google Backup Transport was frozen with TitBkup (but not removed) since 2 hr 52 min ago.
ROM: RemICS-JB v3.0
Kernel: Revolution Kernel v1.5FIX; SIO, SmartAssV2, 300 - 1000 MHz
V6 supercharger applied.
EDIT: The % of Android OS is gradually dropping and it's now only 12% vs screen on at 30%... Probably because I was having screen on.
UPDATE: New cycle drained 5% after 1 hr plus. And android OS took 51% of it, it hit 60% the other day. O_O
So I tried googling and found a very simple suggestion, which is to wipe cache in recovery mode. So i did that and rebooted. The Android OS took only 12% instead of 50% now. I'm leaving it on for some time and will report back if it recurs.
