Battery Doctor Encourages Good Charging Habits on Android:
Android: Description looks good, but would not install on my old or new android tablet, incompatible device message for both devices.
Battery Doctor encourages better overall battery health by well-timed charging.
Battery Doctor uses the best practices of batteries—charging to certain percentages, never letting your charge go below a certain amount, using up fewer cycles—and gives you examples and opportunities to live with them. Instead of just letting you know you're at 64 percent and need to charge, it will tell you that you should charge for 24 minutes soon, or 40 minutes later on today.
