massive battery drain without visible reason ?
many of you will think: "OMG, another drain thread". But this one is special, and really weird. I noticed a significantly lesser screen-on-time on the last days (1 - 1.5h instead of 2.5 - 3.5h). I have changed nothing before, no new apps, no updates... I couldn't identify a cause for this drain with the usual tools due to high usage, so i charged the phone and left it at the desk overnight. the battery drained overnight 80% in 8 hours, and there were nearly no wakelocks, the phone was in deepsleep the whole time (98%). My first thought was, that somehow my omnirom installation was derping, so i wiped dalvik & cache and flashed the rom again without a full wipe (without custom kernel). that didn't fix the problem, so i made a full backup, wiped the complete device (bootloader lock and unlock), reflashed stock google rom (flash_all.bat, so modem etc. is uptodate, too). the drain occured with stock google rom, too. After that, i restored my backup, wiped cache, system and dalvik. after that, the drain still occured, so i thought about a hardware fault and doing a RMA. But since yesterday, the problem is gone as nothing had happened...
So: Is it possible, that the drain was caused somehow by the modem and the cellular provider has fu**ed something up real bad ? A friend of mine has the same problem now (stock google), he resides a few kilometres away in the same town...
