I have a ZTE Blade XMax and I've been having issues with the bluetooth draining battery much faster than it should be. I'm leaning towards it being a software issue because if I do a factory reset on the phone it will resolve the issue for a while and then it'll eventually start having the issue again. If I go into the battery in settings and look under "use since last full charge" the percentage is always a large majority or ALL bluetooth. I know bluetooth uses a fair amount of battery but when the issue is not occuring I get through a day of work with a fair amount of battery left on my phone, 30% or so, and I have the exact same listening habits every day. What kind of software issue could possibly cause problems like this? Some sort of conflict? On a side note I'm quite tired of the phone and it's constant malfunctions and I'll be going away from ZTE for good eventually but I'm trying to milk it. Thanks ahead for any advice!
