Never ignore the yellow battery bar on iPhone – it has two very serious meanings that you need to learn

YOUR iPhone battery bar is probably green most of the time — and sometimes red — but not always.

It can also turn yellow, and this has a very important meaning.

Apple uses the yellow color of the battery icon in the status bar to signal when an iPhone has entered a special state.

This state is called sleep mode, and you may have heard of it.

It’s a setting that reduces the power consumption of your iPhone.

There’s really only two times you might see it, and both are important.

First of all, the battery saver mode offers itself as an automatic prompt when you reach 20% charge.

That’s a very low battery, so don’t ignore the warning: Sleep mode could save you in a crisis.

It should turn off automatically when you recharge your iPhone to 80% or more.

Until you do this, the battery saver mode will remain active unless you turn it off manually.

The second time you might see it is if you accidentally activated the iPhone hack.

That doesn’t seem like a big deal (who doesn’t like extra battery life?), but it can be an issue.

The power saving mode saves energy by restricting certain functions.

So you don’t get the full iPhone experience when the battery saver mode is active.

Here are the features affected by power saving mode:

• 5G (except for video streaming) on ​​iPhone 12 models
• Automatic lock (30 seconds by default)
• screen brightness
• Display refresh rate (limited to 60 Hz) on iPhone and iPad models with ProMotion displays
• Some visual effects
• iCloud Photos (Temporarily Paused)
• Automatic Downloads
• email retrieval
• Update background app

Because of this, Apple indicates users with a yellow icon when they are in sleep mode.

It is important for users to be clear when the power saving mode is active, as you may find that your device is not working normally.

And it’s a good reminder to turn off battery saver mode when you don’t really need it.

If you find that you’re constantly running out of battery, check the Settings > Battery page to see if any apps are using too much charge.

You can also tap Battery Health to see if your battery has been degrading over time.

If your total battery capacity is less than 80% compared to when it was new (which should last about two years), it may be worth purchasing a replacement battery from Apple.

This gives you a fresh battery, can improve phone performance, and is far cheaper than buying a new iPhone.
