So I was wondering whether it is worthwhile at this battery to buy it. The price is of course tempting, and you wonder if it really is an original part at this price. Although I can not really understand the latter, I have to say I'm really surprised. So far I have a battery with twice the capacity, so the one who makes the phone thicker used. He held just a day with occasional gimmicks (Internet etc). Now I use the above battery and will interface with the same strain so far on average 2days and a couple of hours. I can only recommend this battery. Super price, Long performance. Even the delivery was very fast. The next day the goods were already in the mailbox. Since I like to give it 5 stars!
