Before starting to use Halfmind Reminder with batteries, you should check your device's working mode first. If your device is working in Host Mode, it can't enter power-saving mode, which will lead to a very short battery life. Under this mode, wired power is strongly recommended instead. If your device is working under Satellite Mode, then you can proceed.
How to Install Batteries
Take off the back case by turning it anti-clockwise. Insert 3 AAA batteries inside, then close the back case clockwise.
Power-Saving Mode
When working with battery supply, the device will automatically enter power-saving mode to extend battery life as long as possible. Some performance will be affected under this mode. Check the table below to see the differences. You can still change the settings in the device info page on Halfmind Todo.
