‘I love this feature’ cheers iPhone owners on the trick to extend battery life

A SIMPLE iPhone setup can make your battery last much longer.

It is designed to dramatically improve performance health of your iPhone battery.

All lithium-ion batteries – including the batteries inside them iPhones – degrade over time.

They age chemically for many reasons: the way you charge your iPhone and even its temperature can cause a battery to degrade faster.

This means they hold less charge than when they were new, meaning you’ll need to charge more often.

Last year, Apple unveiled a new feature designed to protect your battery and keep it “healthy” for longer.

It’s called the “80% limit” and is designed to keep your iPhone’s battery healthy for longer.

When a battery is fully charged, it is put under pressure – and that is not good.

When this feature is enabled, your iPhone will not charge more than 80% (except in specific circumstances).

You can find it with three taps by going to Settings > Battery > Battery status & charging.

Apple explains: “If you choose the 80% limit, your iPhone will charge to approximately 80 percent and then stop charging.

“If the battery charge level drops to 75 percent, charging will resume until the battery charge level reaches approximately 80 percent again.”

‘I can’t believe it,’ say iPhone owners after finding a secret trick to falling asleep, saying it’s ‘the only way I can sleep’

Apple added: “When the 80% limit is enabled, your iPhone will occasionally charge to 100 percent to maintain accurate battery health estimates.”

But there’s a catch: this setting is only available on the iPhone 15, iPhone 15 Plus iPhone 15 Pro and iPhone 15 Pro Max.

Apple notes that not using this feature “may increase battery wear and shorten its lifespan.”

And that means you’ll have worse battery life in the long run – and you may need to upgrade your battery or smartphone sooner.

iPhone fans raved about the trick in a Reddit thread, with one proverb“I love this feature!”

Another said: “I’m using this feature too. I hope it actually extends my battery life as I usually pass my phones on to family members!”

One added: “From an environmental point of view, it’s better to have a battery last longer than one that runs out sooner. Less replacements in general, you can’t deny that.”

And another commented: “I’ve always charged to 100%, but with iPhone 15 Pro I’m going to give the 80% feature a try. In some ways it makes a lot of sense, like you I have chargers everywhere, and it doesn’t take long to refill the battery.”

OPTIMIZED!

You may see the other mode under Battery Status in your iPhone settings app has optimized battery charging.

This is available on multiple iPhones models – not just the 2023 batch.

It is enabled by default when you set up your iPhone.

Apple explains: “With the feature enabled, your iPhone will delay charging beyond 80% in certain situations.

“Your iPhone uses on-device machine learning to learn your daily charging routine so that optimized battery charging only activates when your iPhone predicts it will be connected to a charger for an extended period of time.

“The algorithm aims to ensure that your iPhone is still fully charged when disconnected.”

You’ll know when optimized battery charging is active because a notification will appear on the lock screen.

This notification indicates when your iPhone needs to be fully charged.

If you want to fully charge it sooner, you can press and hold the notification and then press Charge now.
