So, the title says it all. I have had my rezound for a couple of weeks. I actually had one when they first came out but could not justify $300 with no service at home at the time but I broke down when I got a good deal on ebay. So since getting it I have noticed the horrid battery drain from the acore process but I figured an extended battery would help turn 5 hours to 10, I could live with that. With my standard battery it would get hot (115 degrees F +) and would actually drain while on the charger and screen on. Battery Mix showed quick charge only at night. Moving to my extended battery. Got it in the mail today and have been charging it unsuccessfully. I got a 3500mAH from hyperion which has a great rating on ebay and amazon. Now I plug it into the charger and it will charge for 2 minutes then the LED flashes orange and green (overheating) for a minute then back to charging when screen on or off, power on or off. Here's the bass ackwords part, the battery temp of the extended battery has not gone over 77 degrees F in the 3 hours on the charger, apps running and screen on. I am baffled that it says overheating at battery temp 77 with ext battery but not with standard battery at 115+. What Gives? I know it is probably the phone at this point but am not sure if VZW will replace under warranty because it was not purchased from VZW. I do pay for the total equipment protection on my account and am afraid to call and ask just to find out they won't do anything under warranty/insurance. Any thoughts?
