[Q] Is it necessary to wipe the battery stat after new Rom installed?

[peterlolty]

As same as the title, I found several posts said that the battery stat would be incorrect and it should be wipe after a new Rom installed.

My question is:

1. Aren't we do the 3 wipe before installing the new Rom and the battery stat should be also wiped?

2. Why the Android OS needs the battery stat file to determine the battery status?

I don't believe so because I think when the dalvik gets wiped, it wipes that too.
