Well organized my emails, quick alert for new mails, and allow you to separate your mail account if you have more than one account.
Battery draining
Vidthaya
My iPhone 14 Pro Max’s battery has been unexplainably consuming more power, that my phone would die in half day. I have been trying to find the cause and ended up seeing that Spark is the app that has consumed the most battery in the past weeks. I did not even open the app that much. The app just used background activity too much even if I turned it off in settings. After deleting the app, my phone’s battery came back to its normal cycle.
