Useful Power
I've had it about three weeks and it is now giving me up to three days power (depending on useage) between charges. A day's Geocaching is nothing for this battery and I still have more than a days charge left. 30% power left will still see me through the day.
I would certainly recommend this battery pack and I have found the increased size and weight of the phone no problem at all. In fact it is a small price to pay for the benefit it has given me. I was also able to buy the unit at a very attractive price - thank you for that and for the good service all round.
