Since updating to the latest version, I was experiencing high 3G drain, even if reverting to an older stock-based ROM from backup or fully wiping and reinstalling.
Yesterday while out, battery was plummetting on 3g, so I switched to 2g and it was drastically improved... now here's the biggie. I NEVER switch to 2G. But yesterday, running CM11 with 2g only enabled, I rebooted into recovery, did full wipes, and restored a B199 stock backup. When it booted, it had 2G only enabled. I KNOW that the backed-up state was 3g. So I am concluding that the wipe and restore is NOT restoring something properly. I know this sounds bizarre. So last night, I installed the latest CWM, did full wipes and reflashed B199 stock, and have no significant battery drain on 3G again.
