We've all been there.When we need to really do something and your phone's dead, it all goes bad.Use these tips and you'll have a good difference.
Go to settings>general>background app refresh and only leave on the apps you NEED up to date.This is one of the places where good battery can get wiped out.
Go to control center from the bottom of the screen.Turn off airdrop.Only turn it on if you need it at a certian time.This is another loophole where battery sweeps out.
Since you're still in control center,turn off bluetooth and/or wifi(I only leave wifi on for ipods).Also,lower your brightness to the lowest place thats comfy for you,or the 50% mark.
This is an optional thing.I've heard that getting rid of apps on multitasking doesn't really affect battery.I still do it,but this is on you.
I hope this helps a lot of people! Comment if this helped! Don't forget to follow.
UPDATE: airdrop is only for:iPhone 5 and later,iPod touch 5th gen. and later,iPad 4th gen. and later,and iPad mini
