I'm posting this to basically to document our experience with the EVO 4G. My wife and I both have an EGO 4G which was purchased last March 2011 or maybe it was April 2011. Both worked fine up until around beginning of July when all of the sudden I was having problems with data connection. I ran thru update after update and now finally it started working again though it isn't as good as it was before as I still occasionally get data connection errors. My wifes phone worked great up until about the beginning of August. Since the beginning of August she has gone thru about 3 batteries as they keep saying it needs a battery. The problem is it just won't turn on and sometimes won't charge. She only uses a wall charger and a car charger. My phone Hardware version 0004 Android version 2.3.3 (since I updated trying to fix the data issue) Her Phone Hardware version 0004 Software version 2.2 Her phone just randomly seems to stop charging. Sometimes it won't come on sometimes it does. Last night I swapped the batteries since they keep giving us new ones. My phone charged her battery to 100% (well 94% after a few minutes of use) and had a green light this morning. Her phone charged my battery to 64% and still had an orange light Her phone was using the HTC charger that came with it plugged into the wall mine was using a sanyo charger that came with another phone. I've never had a problem with my battery. So her phone only charging it to 64% after like 8 hours of charge time tells me it has nothing to do with the battery. In fact I believe it had more charge before it was plugged in and after charging it all night it lost power. Neither phone was turned on while charging they both were off. In the past 20 minutes her phone with her battery (that was at 94%) is now at 98%. At this point it seems to me that the HTC charger that came with the phone is a piece of !$!@.
