Millions of iPhone users are just now realizing that there is a “life-changing” charging hack

APPLE fans have just now discovered a handy feature on their iPhones that will save you from running out of battery.

But the “life-changing” trick only works if you have a fellow iPhone user by your side.

It can be frustrating when your phone dies at a crucial moment and there is nowhere to plug in the charger.

But if you have a friend by your side who is also an iPhone owner, you might be in luck.

iPhone 15 can act as a portable charger with this one smart charging feature.

You can charge other Apple devices, e.g models iPhone, Airpods and Apple Watch using your mobile device.

Apple’s website explains that if both devices have a USB-C connector, you can connect them and share the battery.

If there are two iPhones, then the one with the higher battery level will charge the other.

When connected, the iPhone will automatically recognize which phone has a lower battery percentage and will charge it without draining itself.

And this option is not only limited to the iPhone 15, because you can increase the battery in older models as well.

You just have to make sure you have a USB-C cable for lighting, as the iPhone 15 had to switch from Apple’s signature cable.

One user shared online that his iPhone 15 lost nine percent of its battery to boost the iPhone 11 from 10 to 32 percent.

Unfortunately, this feature isn’t available on older iPhones, and they can’t charge each other, even the iPhone 15.

The charging hack has been hailed as a modern-day romantic gesture, as it allows you to show another iPhone user that you “really love” them.

One person wrote on Twitter: “This is how you show someone you really love them.”

Another said: “This is it future.”

A third person wrote: “That might be useful.”

But others weren’t convinced and remained skeptical about the feature’s effect on the phone’s battery life.

One person said: “I’m not sure if I want to charge other people’s phones, I’m keeping my battery.”

Another wrote: “Yes it’s great but you’ll fry your phone.”

“It will hurt battery life,” someone else added.

One tech whistleblower shared a simple trick that can boost your iPhone’s battery life in just ten seconds.

Another tech guru pointed out all the things that can be unexpected battery drain for your iPhone.

With a few simple settings changes, you can save some juice.

Someone else pointed out a sneaky background feature that could be draining it without you knowing!

Apple also revealed a “quick charge” trick that works on millions of iPhones but fails if it’s too cold.

Battery saving tips

There are a few other things you can do when your device is on low power, such as enabling low power mode.

This handy tool for iPhone helps extend battery life when your device is running low on juice.

To turn Low Power Mode on or off, go to Settings, then Battery, and toggle Low Power Mode.

Another setting you can adjust that causes battery drain is screen brightness.

Some experts suggest that keeping your screen brightness somewhere between 65% and 70% can save you a lot of battery power.

However, you should keep your brightness as low as your eyes can comfortably handle.

To change the brightness levels, simply slide your fingers down from the top right corner of the home screen.

Once you’ve done this, you should see a brightness slider – adjust it as you like.
