Star Star Star Star Star Seidio Innocell 3300mAh Extended Battery
User: JP P, Apr 18, 2011
Pros: GREAT Performance
Cons: Cant find a case to fit the phone.
This battery does ALL it claims. I have never had performance out of a cell phone like this. I can go through two full days with heavy usage and still have a charge. Incredible! Now if I could just find a case for my Epic that fits with the battery Id be in heaven.
Star Star Star Star Star big but worth it

Pros: last a long time!
Cons: a little extra thick
I got this battery after some recommendations and I feel like it is totally worth the cost and weight. I used to have to charge my phone constantly throughout the day to make sure it actually last all day which for me is usually about 20 hour days. I work in IT and its important to be available.

Now, I barely charge it during the day, its usually in my pocket and im answering about 40 more calls and getting more work done on the go. I can go on day trips and not worry about being out of contact. I can go 20 hours just fine , itll be low but at least not dead.

The difference is, before I would keep the phone in my pocket and not use it. Now I have it in my pocket and its getting email, playing radio, synchronizing and waiting for alerts.

Regular battery would lose 30 in 1.5 hours of playing pandora over 3g. This battery loses only 8 in 1.5 hours of playing pandora over 3g.

I know its bulky but I cant go back to the default battery ever again!

Pros: Incredibly impressive battery life
Cons: Adds a fair amount of bulk
I will keep this short and sweet- the only thing holding me back from truly loving my samsung Epic was the fact that I was deathly afraid of using it for fear its less than stellar battery would crap out on me around noon (as a heavy texter, twitter user, etc. This was rather commonplace), but now with this battery I couldnt drain it in a single day if I tried. If you are an Android power user (or any kind of user at all, for that matter) invest in one of these! You wont even mind the little bit of additional bulk, promise

Star Star Star Star Star overheating and weak cover
User: Laura N, Feb 1, 2012
Pros: battery lasts all day
Cons: cover falls off and the phone overheats
I was happy to get this battery and be able to use the phone all day. A first since I had bought the epic 4G. but it makes the phone HUGE. and the phone gets super hot now, it crashes frequently, (which may or may not have to do with the battery). but also the cover has weakened after using it, and it falls off multiple times a day. i have to tape it on, which looks and feels ridiculous.

they need to fix the design for the cover for this to be legit.
