text: Doubles My Battery Life.....Hands Down.
  
  After calibrating this extended battery via full 2 cycle discharge and charge I can confidently say it was a great buy. This has fixed one of the few flaws in my v20, now I can comfortably go 2 full days without charging with moderate use with almost 7 hours screen time, while still maintaining fast charging. There are some minor short comings. The case does not offer much in protection as others have mentioned, the bump surrounding the screen is quite small. Also the screen protector will protect at minor scratches at best but not from drop damage as its not a full glass version. The front camera is also exposed. There is the issue with having to remove the case to fully insert the charger. So I'm taking off a star for that. Still highly recommended would buy again.
