Advance Charging Controller for Android

Love it. Controlling charge current & setting a max charge % should be a big boost to battery lidecycles.

I'm curious if phones actually know their battery charge rate. I believe they know how much power comes in to the phone, but being able to differntiate between power going to the battery versus the rest of the phone would be awesome. Being able to say, charge at 100ma & have that really happen would be exceptionally cool.

I want to know opinions of people who are using this script ,is it worth ?
