I currently have the “official” extended battery by Verizon for the HTC Thunderbolt that comes with a different back cover. That battery is 2750mAh and I can get 2 full days off of 1 charge, assuming I turn my phone off at night time and I only listen to music to and from work, and while I’m at the gym.
I’m getting sick of having to carry around this brick in my pocket. This is the heaviest phone I’ve ever owned and when I put the phone in my pocket, my pants start to sag!
Don’t get me wrong, I still love the phone! It’s fast, nice big screen, and way better than an iPhone! I ordered two batteries off eBay today that claim to be extended batteries but don’t require a new back cover. Therefore, I can put the original cover back on the phone making in slimmer and lighter. The Thunderbolt’s original battery was a 1400mAh battery. I’m not quite sure how much longer I’m going to get out of these batteries since they’re only offering an extra 300mAh. I’m hoping for maybe an extra 3 hours, but that might be pushing it. If anyone is reading this, please let me know what you think?
The seller offered 7 day money back guarantee and his feedback was pretty outstanding. Let’s hope for the best!
