Star Star Star Star Star Battery-great! Back is terrible
User: Aaron T, May 10, 2011
Pros: Great battery life
Cons: Poor door design
It seems to have doubled my use time. Hard to tell as Im very inconsistent with my data use.

Size? Coming from the old Nextel camp it makes the Hero feel much more like a REAL phone. (g) Little thicker and a little heftier.

As for the door, I finally got so tired of it popping off when I put it in a case or taking it out that I resorted to applying clear electrical tape on both sides to hold it in place. Much thinner plastic than the original.

Been working fine for almost a year (with the occasional replacement of the tape).

It works and is not THAT bad looking. (Like I care bout looks!)
Star Star Star Star Star Hero runs twice as long between charges
User: PK K, Jun 28, 2010
Pros: Long battery run time, great back cover design for camera access
Cons: Back cover disconnects occasionally
Buy this battery if you want to run your Hero all day without charging. Spring Hero updated to 2.1.
Star Star Star Star Star The Battery makes the phone last FOREVER
User: Jorge L, Apr 12, 2010
Pros: Battery Works
Cons: The case sucks
I am so happy that my phone lasts forever now. I reasonably expect my phone to go from 7am until 10pm without needing a charge. Thats with 4 hours of Pandora playing and another 3-4 hours of internet/app usage. I do use a task manager often to ensure longevity. The case is bad, it doesnt not fasten snug like the original and sometimes it will pop off in my pocket. It also feels cheap, very cheap.

Summary: More than twice the phone time, fat boy phone, annoying back cover. Worth it for me because I need to use time.
