My phone is closeing itself below 30% like the battery is finished when it's drained fast as 3g surfing etc. So I want to change my battery with an OEM-one. I live in Turkey and Apple doesn't seem to open its AppleStore until a few weeks here. I'm thinking about to buy one from alie. or dx. Is there anyone that you could suggest, I usually read comments before purchasing something but when it's about batteries I can not find any reliable comment.
