Mail Causing battery draining on iPhone iOS 11
Hello
I m using an iPhone 7 with iOS 11.2
I noticed , in the battery statistics , that mail shows 8 minutes of usage , 7 in background but it was responsible for the 23% of the battery usage in the last 25 hours.
This keeps happening every day.
I have 4 email accounts : 2 set on push , 2 on fetch every 30 minutes. Always had this 4 since the previous iPhones, but this problem started to show up with iOS 11 .
i don't want to set everything to manual......i wouldn't want to...
iPhone 7, iOS 11.2.1
