Hi All, I like to think of myself as a moderately advanced user but I don't mind admitting I don't have a clue when it comes to this. I've recently invested in an Anker 1900 mAh battery for my S2 after reading great reviews online. I was planning on putting it in tonight when I go to bed and giving it its first full charge overnight. Here's my question: I'm going to be replacing the stock 1650mAh battery with this so do I need to recalibrate? And if so, what do I need to do and when? What difference will it make? I'm rooted and have Titanium Pro and Superuser and all that malarkey. Thanks in advance. P.
