I've had this phone about 100 days - give or take.
Phone history: Use the factory wall plug every night. I will also often have to top-off at work via a USB cable hooked to my laptop computer. I'm in a WiFi environment almost every day - I tend not to keep Data on. Actually, I generally only turn WiFi on when I need it.
Issues:
When battery gets down to 14% - the low battery warning will not go away. It comes back repeatedly until phone is either dead or plugged in. Basically renders the phone useless (pretty sure I've read a thread on this)
Battery icon will often show the "bolt" when not plugged in; and often won't show the "bolt" when plugged in (read about this one, too)
USB connectivity icon will often stay after phone has been unplugged from USB / computer charger
When battery gets down to less than 50%; often times the screen will come on as if the power button has been tapped
Often cannot turn data on with either phone controls or via a widget - must reboot phone to get data to work (WiFi has no issues coming on/off)
herky/jerky movement of apps (Euchre, Angry Birds, etc) as they're being utilized - even after clearing "recently run" apps. Sometimes even does this after re-boot
Would really appreciate the advice from one of the "Pros" on what I can do with this cruddy phone.
