Since the MM update I have had horrible battery drain and any wifi I connect to is virtually impossible to use.... In the last 3 weeks I have performed 2 Factory resets and replaced the battery with an original Samsung replacement. All apps are optimized and I have NO other apps installed other than what was on the phone since day one. It appears there is something keeping the phone in a wakelock condition. I am in a good service zone so that is not it. I have had pretty poor battery issues since the 5.0 update but not this bad. I can barely get 8 hours of MINIMAL use before the battery is dead. I have the extended warranty/service plan. Can I get this replaced under that plan? The phone has very minor scratches around the bezel... I don't know what else to do. I need to get these 2 issues straightened out. I pay for Wifi at home but can't use it as my phone will not load anything on that connection while my laptop works just fine as does the GF's S5 also on MM...
