Do i need to recalibrate battery?

[elosogrande7076]

Hey guys,

I have a quick question. I am currently running one of Silence's custom ROMS but have been switching/flashing between other chef's and I noticed that my battery life is still pretty good but will go down kinda fast till it gets to the 59% (60% if i use a rom that does the 10% increments). After it gets down to that spot it will stay there for a long time (several hours) then start going down to 0 at a regular pace according to activity (more if Im online/talking or steady if its idle). Is this regular? In the beginning it will just gradually go down to 0 so i wasnt sure if this is normal. If its not, any ideas what I could do?

Thanks
