I have the battery for my Samsung touch since about 3 weeks. I'm constantly online and mobile write many messages every now and then I play Angry Birds and make a lot of photos. The original battery lasted me more than 12 hours. When I was economical with the energy. The power battery held in full use by 1.5 days. So I am very happy with it. Unfortunately, there is what to say to the size of the battery, because the note is Galasy already a very large smartphone - fortunately it is very schmall! But with the power battery provides the notes of how a cell phone !!! Madness! No case fits more going back, if the phone should fall off times, it has completely no protection and it can easily happen that the chrome edges scratch. Would be very a pity! I will keep the battery of course, just in case. Property me but now a ZNEX POWERPACK XM | 11000mAh | output 1.1A | External high-capacity battery (0_s00_i00) ordered, at which one can be mobile (and many other devices) charge, and will use the original battery.
Otherwise, the delivery was very fast and everything packed undamaged and original.
Who as size does not bother with this battery makes nothing wrong.
