Appalling battery performance, Wakelocks. Please help.
My M8 went from being the best phone I've ever had in terms of battery performance, to being utterly awful a few days back. I organised an exchange, but in the time I was waiting for the exchange to take place, a factory reset seemed to fix it. Still went with the exchange anyway.
I restored from HTC backup, and this one is having the same issue, battery wise. Also heating up sporadically. GSAM tells me I am getting an awful lot of BAM_DMUX_WAKELOCK and I've tried uninstalling apps, factory wiping and HTC restore, factory wiping and Google restore only, factory wiping and everything manually, and factory wiping and leaving it completely stock and nothing seems to make any difference.
Any ideas? It's bugging the hell out of me, I get about 12-16hrs of life with the phone barely being used now, whereas before I could get through a day of moderate to heavy use with more than half charge left.
Should I try another exchange?
