We consistently make updates to improve battery life so please make sure you always download the most recent version of MobileDay. We recommend using Wi-Fi instead of a cell network whenever possible.
Here are some common reasons for battery drain:
1) MobileDay will check our database for new information each time your iPhone or Android calendar refreshes. A more frequent refresh rate (which is needed for people who have calendars that change on short notice) will use more battery life.
2) Those users who have multiple calendars with many meetings running simultaneously on their native calendar may also see more battery usage.
3) MobileDay might also use additional battery life while you are traveling in rural areas with poor signal strength or when you are changing cell towers frequently.
