Here's how to change auto lock on an iPhone. Check it out!

One of the most power hungry parts of an iPhone is the screen on it. The screen is the biggest consumer of battery power when it is lit up. So having it on when you don't really need it on can waste a lot of power unnecessarily and drain your battery even quicker.

There are a few ways you can save some of this power. You can lower your screen brightness levels a bit in settings, this will help reduce the amount of power consumption a little even if the screen remains on.

If your iPhone is a slightly older one and does not hold a charge for as long as it used to, you can switch the Low Power Mode on to save as much battery life as possible. This is especially helpful if you need to get through the day and will have no option to charge your iPhone during the day.

Another power saving tactic is to set your screen, Auto Lock, to the shortest duration you are comfortable with, that way the screen turns itself off as soon as possible when it is not in use. Although having a very short limit may be frustrating when you are actually using your iPhone but stop only for short periods.
