MIR/fellow EVO 4G LTE users, wtf has happened to my battery in the last week?
Battery used to last well over 24 hours, now the thing drains in less than half a day, even if it is pretty much idle. I've tried a lot of things too, no explanation. I've seen people bitching about the jelly bean upgrade as the reason, but i don't understand. I downloaded jelly bean months ago with no problems. The last week or so has been hilarious in terms of battery life.
I live in a place that struggles with reception so when I'm not moving my phone is constantly on the charger. Searching for signal is the ultimate battery drain.
The problem has gone away. The only things I have done is A) uninstalled the Groupon app after noticing that it was draining loads of battery even when I had not opened the app for days, and B) I let the battery completely drain itself before plugging it in a couple times. Now it's back to normal.
PS I could not find any settings in the groupon app for syncing or anything like that, so I'm not sure why it was using so much battery without me ever opening it. I re-downloaded the app, and boom, it happened again. So I uninstalled it again. I guess it just doesn't get along with the EVO.
