Honestly? I don't have the patience to do that! Seriously! But, I actually did delete the bin file after rooting the phone. Didn't make any difference.
Got the new battery using it right now and yeah! There is just one difference between the two and it's that ke there is a slight improvement in the backup, that's it.
genuine one or from other manufacturers ? price ?
your old battery , did u notice some deformation or bulging ?
