Until recently I was wondering why my iphone always heats up for no apparent reason, this has been happening since a couple of months ago,

The battery drains really quickly as well, already replaced it 2 months ago,

It happens when charging, during usage, sometimes even when not doing anything,

Until I found out that the mail app is the one causing this, at times it kept running on the background for hours,

So I deleted the original mail app and moved to alternative email app,

Been a week without a hitch, battery life was fine, until just now suddenly my phone heats up again,

Lo and behold, recently deleted app is working on the background,

    Lolol restart phone to complete unlinking files

    Turn off auto fetch.
    It won't run in the background that way.

    Settings -> passwords and accounts -> fetch new data -> select account

    @melezorus34 that did the trick, though I've already hard reset once after deleting the mail app, let's see if it doesn't happen again

    @C0D4 that's the first thing I tried, I got 3 accounts connected and all fetch set to manual, I even turned off background refresh for all apps lol

    Are you running beta releases?
    they can have battery issues, reason I stopped using them actually.

    If not, try a full restore if you can.

    @C0D4 nope, I've never touched beta releases, I'm actually still using 12 the first time it happened,

    I'll try a full restore if this persist
