Trying to figure out an app that will charge my phone to a specified percentage, then stop, and if necessary begin recharging it if it drops below a certain threshold. Searches have me at an Open Source app called AccA. In order to operate it, it’s said I need root access though.
Does anyone know (or have some resources/advice) how to obtain root access? I’m looking for more-or-less someone with some been-there-done-that successful experience before I try to do anything on my system to risk messing it up.
