First advice is always wipe and upgrade to latest, listing kernel would help and you should also get betterbattery to check wake locks.Hey all,
This may be a bit antiquated since M4 is out, but I am running M3 and lately my battery life has been awful, with little or no changes to applications/usage/etc. I noticed under the battery info that the CPU isn't allowing the device to go to sleep. For instance, I have been unplugged for ~3 hours and am at 67% battery, with 2h24m Keep Awake time. Any ideas? Would just upgrading to M4 be a simple fix, seeing as I would probably have to wipe to "cure" my M3 of this problem?
