Well, I would not say it holds better than the original battery (for me that I did not feel as she held one day and a half in this debut is not the case for Anker ). However, it holds well the day or even more if you use little phone. We must therefore think about such recharge every night if you do not want to be in the harbor the next day. But this is already the case for most smartphone. In short, for the price, I think it is still worth a shot.
