Q: Can Battery Doctor save power and extend battery life?
A: Yes
Tap the circle at the home screen (Save Juice) to kill power hog apps that are not currently in use to improve battery life
Run our app while charging to let Battery Doctor manage the process with its unique 3 stage charging system that ensures a longer battery life
Use the ''Tasks Killer'' widget to optimize your power consumption conveniently

Q: What is a full charge and why does it matter?
A: Batteries have memories, these memories are manipulated by charging habits so the manner in which you charge your device is very important. Plug in your phone when the battery has about 20% remaining and continue to charge until Battery Doctor tells you the 3rd stage of trickle charging is complete. Do not overcharge by keeping your device plugged in nor undercharge by charging in short bursts whenever convenient.

Q: How does ''Saving Mode'' work?
A: ''Saving Mode'' is an extreme setting that shuts down all non-essential functions of your phone with exception of making phone calls and sending/receiving text messages. Wifi, Data, GPS, etc will all be shut down to ensure battery life and defend your juice.

Q: How do I set up the widgets?
A: The ''Tasks Killer'' widget will automatically appear on your home screen with installation. The other widget that monitors wifi/gps/etc can be installed just as any other widget on your device would be set up.
