I'm well aware of the common issues that cause battery drains, such as app wakelocks, Google Play Services, wifi scanning, location etc... Sometimes my phone's battery just tanks @ idle, dropping like 5-10% per hour, with nothing causing wakelocks at all. Normally, my phone probably drains < 1% per hour, so obviously it's an issue.
I was able to fix the issue after going into recovery and wiping cache/dalvik and what not, but it's really odd. It seems like the phone sometimes just can't measure the % correctly.
And again, my phone generally drains <1% per hour, and when the issue occurs, I check my phone and I see it tank to like 40% after 5-6 hours idling when settings were not altered.
Does anyone else have similar issues as this??
