iON can be installed on any S60 while offering the control of operating time remaining to complete discharge, providing the estimated future date and time of the battery being completely discharged and presenting how long the battery holds its charge on average. The iON provides data in three ways - the main application, the standby plug-in and dedicated power saver.
* Provides information about:
o Operating time remaining to complete discharge,
o Estimated future date and time of the battery being completely discharged,
o How long the battery holds its charge on average,
* Fast and handy access to remaining operating time at the home/standby screen.
* Power saver with additional the ‘big’ battery levels percentages indicator, built-in system notifications (e.g. missed calls, messages, unread emails, current profile, keypad lock).
During the installation you will be prompted for accepting required installation on your device memory not an additional card (uses small amount of memory, about 150kb). It also needs background ‘Core’ process which must starts automatically each boot time and utilizes device CPU in less than 1% once per minute.
