I don't use email a ton, much less than the other apps listed at the top of my usage chart. I closed the app via the switcher last night and it's still at the top with 19%. I killed the app last night and woke up and it had more usage even after not touching my phone for 8 hours. Background app refresh is completely off Anyone know why? I have push off and fetch set to every 30 mins. I deleted my Gmail account through Mail last night as I'm switching back to Mailbox. I probably just have to wait another day or so for the usage statistics to change.
