I have had my Thunderbolt for a week and a half and have already swapped it out for a new Thunderbolt and have been on the phone with Verizon Tech support and to the Verizon store almost every single day since I got it. My 2 biggest issues were: the battery (I know it's not going to last long but...2 & 1/2 hrs to drain after having it for 5 days??) And yes, I know all about my running applications and switching from 3G and 4G to save battery life. But still - it seems ridiculous for a battery to last that little amount of time, especially since I didn't even make a phone call or check my email on it in those 2 & 1/2 hrs. #2 issue and probably my biggest complaint is this: my phone will say "4G LTE" with 4 reception bars and it won't connect to any web page. I will go to my wireless settings and the "Mobile Network" will just keep saying "turning on...". That was the reason I had to trade out my 1st Thunderbolt. I really want to love this phone and when it works, it works great and is superfast but it has NOT worked so much in the week and a half of having it that I am starting to HATE it...
