People are just realizing iPhone settings trick gives you battery boost – it’s easy to get it wrong

A CLEVER feature on your iPhone can give your battery a very handy boost.

It's important to make sure you've got it set up – you'll thank yourself later.

The feature is called Optimized Battery Charging, and it's designed to

As you charge and discharge your iPhone over the months and years, your total battery capacity will shrink.

That means after two years of charging, you're likely to have lost around 20% of total capacity.

But you can slow this loss down by taking advantage of a clever iPhone hack called Optimized Battery Charging.

"As lithium-ion batteries chemically age, the amount of charge they can hold diminishes, resulting in reduced battery life and reduced peak performance," Apple explained.

"With iOS 13 and later, Optimized Battery Charging is designed to reduce the wear on your battery and improve its lifespan by reducing the time your iPhone spends fully charged."

It works by limiting the amount of time that your iPhone spends fully charged.

This reduces the stress on the battery, which improves its health.

So you'll find that you have a healthier battery in the long run – giving you better charge down the line.

The feature delays charging beyond 80%.

Your iPhone will use machine learning to understand your daily routine, and work out the best time to do this.

That means Optimized Battery Charging will only kick in when it thinks your iPhone will be on charge for a while.

For many people, this will be at night – although your own pattern might be different.

Your iPhone will complete the final 20% charge just before it thinks you'll need it.

Of course, you can override the feature at any time.

How to activate Optimized Battery Charging

The good news is that if you have iOS 13, Optimized Battery Charging is on by default.

To make sure you haven't turned it off, go to Settings > Battery > Battery Health & Charging.

Then look for Optimized Battery Charging and make sure the toggle is in.

But the feature won't work unless you have some other settings active.

This is the key part that people miss, so check your settings right now.

According to Apple, you need to make sure the following settings are switched on:

• Settings > Privacy & Security > Location Services > Location Services
• Settings > Privacy & Security > Location Services > System Services > System Customization
• Settings > Privacy & Security > Location Services > System Services > Significant Locations > Significant Locations

The other important point to note is that the feature needs "at least 14 days to learn your charging habits", the iPhone maker explained.

Apple added: "Also, your iPhone needs to experience at least 9 charges of 5 hours or more in a given location for Optimized Battery Charging to engage."
