I'm not root ... and have no plans to be ... so I'll just play the wait and see game then. I'll rotate through all three batteries and let them expend all the way out a couple times each ... maybe that will help.
Otherwise, I just have to 'know' that 10% = done!
For $15 for three batteries + charger, that'll be quite alright.
I am doing the same thing, I have three Laza batteries and three HTC batteries but never had an extended battery... The battery guage is usually about right, but I only trust GSAM Battery Monitor.
