How to make the battery more durable
1. About 0.1% of the total battery energy will be used to turn on the backlight for
15 minutes. For users who need backlight and also have to frequently press
the key during use, the battery will be consumed much faster. Assume the
backlight will be on for 15 minutes a day, then in a year, it already used up
36.5 % of the total battery energy just for backlight. We recommend our users
to enable the auto backlight function, so the backlight will not be
unnecessarily turned on.
2. The shortest measurement interval for the INNO 320 is 10 seconds. However,
for most usage scenarios, a measurement interval of 5 minutes to 15 minutes
is sufficient. The faster the measurement rate, the higher the power
consumption. We recommend our users to choose the measurement rate that
suits their applications. When the user selects a different measurement
interval, the application software will calculate the number of days of the
remaining battery capacity can be used. The user can use this as a reference
to select the measurement interval that can fulfill their application scenario,
