Ok, thanks! Do you think my range (30% to 70%) is "optimal" for the battery?With your routine, you still need to let the battery discharge to 15 - 20 and then charge to 100% twice a month.
I use the built-in Stickies app and have a sticky on my Home Screen that shows the dates when I did a full calibration of the battery. You might consider doing something like that as well.
BTW, does anyone know of an app that has an option to RELIABLY alert me when the battery level goes done so a set level (in my case 30%)?
