Now there are a lot of articles out there that will tell you to start by turning off background app refresh. Okay, we’ll instead of doing that, let’s do something even better…
If you’re running the latest version of iOS your iPhone, you’ve got a Low Power Mode which “temporarily reduces power consumption”. Well it does that by, you guessed it, disabling background app refresh. But it also takes things a bit further by turning off mail fetch, automatic downloads and some of your phone’s visual effects. So if you’re going to do one you might as well do them all at once with the flick of a switch.

To adjust your notification settings go to Settings > Notifications. To turn off location services to to Settings > Privacy > Location Services and flip the switch to off.

Finally you can try reducing animations in iOS because overtime you open a folder or launch an app, those zoom in or zoom out animations use the processor which saps a bit of battery life. To turn them off go to Settings > General ...
