Just a few weeks ago I started to see slowness on my phone. Meaning whenver I press an icon, type, etc...there's a delay. I have advanced task manager and fast reboot, but that doesn't help. It does help however when I restart my phone and within the day I start experiencing the response time issue again. During work I end up restarting my phone 3 times a day. What I've also noticed is that the battery life drains quicker than usual. I would say within 6 hours my battery would be gone, without using my phone. So I'm thinking there's a process running in the background that's eating up my memory, but when I look at current running apps there's nothing out of the ordinary. I'm using Maty's 215 (6.16.215.XT912). How do I track what process is dragging my phone? Is there a new update I should be using from the 215? Also, I purchased my Maxx from Ebay 6 months ago and I have never got the Maxx to go long in battery life as advertised. I've factor reset my phone serval times, battery caliberation. If I don't use my phone, it will last up to a good 12 hours without charging. But if I'm emailing, phone, web browsing, it will only last 6 hours. Is it safe to purchase phones through EBay? Meaning, whatever application, tweaks that the previous owner has done, doing a factory reset basically baselines everything from scratch? Thanks.
