I use this battery for 1 month now and my laptop does not even take a whole day! Yet to save the battery, I'm not constantly on 3G, I do not surf much, I do not listen to music. I "check" my emails 2-3 times a day (no push up). What makes me say that I doubt that this is an HTC product, this is my 2nd HTC replacement battery for my phone. The first gave me satisfaction and has given a new autonomy in my mobile. Not this one ...
Before choosing original batteries "HTC" I ordered on Amazon, a battery noname ten euros ... and I got my money, ie a battery holding 3 5:00
