→Battery life: Fixed grammar and improved writing
The Pokéwalker contains a 3V CR2032 battery with a capacity of 220–225 mAh. The battery will last approximately four months if the Pokéwalker device is used 30 minutes a day and about 10,000 steps are taken. This will vary depending on the temperature, the number of steps taken, how often the Pokéwalker is used, how often infrared communication is used, and how often the buttons are pressed. If the battery power gets low, a battery icon will appear on the top-left corner of the display and the Pokéwalker will save the information once every hour before the battery runs out. The battery is currently not rechargeable and must be replaced with another 3V CR2032 battery if it runs out. If the Pokéwalker's battery runs out and the session is not saved, all steps will be lost and all watts, items and Pokémon that were obtained during the trip will be deleted
, however the Pokémon deposited at the start of the session will remain unaffected.
To sustain battery life
in the midst of a session, the Pokéwalker puts itself into sleep mode after 60–90 seconds of inactivity, so the display will turn off and the screen will go blank. The Pokéwalker can be revived by holding down the central button for one second. While in sleep mode, the Pokéwalker will still maintain its primary function and record the amount of steps the player takes. The device's settings can also be set in order to turn the display sharpness down and decrease or mute the sound, as a way to conserve battery life. To replace the battery, a Phillips-head screwdriver is needed to remove the plain backing or the optional belt clip. Removing the battery will cause all steps taken and watts obtained to be cleared. The Pokémon inside will not be erased.
