Pros: Never have to recharge except overnight
Cons: A bit heavy and bulky, but worth it
I had become dissatisfied with my HTC Thunderbolt because of the battery that came with the phone. I finally looked on the internet for a better battery and found it! Now I am able to enjoy the functionality of my Thunderbolt without worrying about my battery charge.

Star Star Star Star Star What A Difference
User: Bob W, Feb 22, 2012
Pros: Impressive length of charge
Cons: None
This is an awesome battery. The stock battery is only 1400mAh, and it needed recharging after just a single day of moderate use. The Innocell 3200mAh battery lasts me 2-3 days. I also bought a nifty hard case from HTC Depot which accommodates the thicker 3200mAh battery. Im all set! What great service. Will spread the word!
