Okie Here Is The Battery Result As I Test.

Firstly Compare Between Stock Battery ( 720p Video Play Back On HTC Desire HD )

Normally I See This Video http://www.youtube.com/watch?v=_sa1GWrN6eQ its 20 Minutes Long And At Stock Battery After I Finish This Video Battery Drop 5%. But On The 2450 Mah Battery I Replay This Video For 2 Times Full Only Drop 2%.

Secondly Compare Between Stock Battery ( 320 KBPS Music Play Back On HTC Desire HD )

Normally I Listen To SNSD Music And Now I Test My Whole SNSD Music Album Got Around 36 Music On Stock Battery And It Drop 10%. But On The 2450 Mah Battery It Drop Only 7%.

Thirdly Compare Between Stock Battery ( Shooting Picture With Flash And Without Flash )

With Flash For 100 Shoot Of Picture On Stock Battery Drop 17% And The Phone Turn To Be Hot. But On The 2450 Mah Battery 100 Shoot Of Picture With Full Flash Battery Drop 8 %

Without Flash For 100 Shoot Of Picture On Stock Battery Drop 11%. But On The 2450 Mah Battery 100 Shoot Of Picture Without Flash Drop 6 %

Fourthly Compare Between Stock Battery ( Bluetooth 2 GB File ) ( Takes 41 Minutes To Finish Bluetooth )

Stock Battery Drop 44% And The Phone Turn To Be Hot. But On The 2450 Mah Battery Drop 31% Same The Phone Turn To Be Hot.

Fifthly Compare Between Stock Battery ( Wifi Download 2 GB File ) ( My House Unifi So Takes 29 Minutes To Finish )
