[2025] Does iPhone Charge Faster on Low Power Mode?

The Low Power mode is a very convenient feature that helps extend your iPhone’s battery life by limiting most of your phone’s background functionality like reducing the display brightness, system animations, app refresh, etc.

Many users wonder whether iPhone charges faster on Low Power mode. Well, that’s what we’re going to find out in this article. So keep reading!

What is Low Power Mode on iPhone?

Before discussing the effect that Low Power mode has on iPhone charging speed, let’s first understand what this mode actually does. As the name suggests, when you enable this feature, your iPhone immediately enters a low-power diet to further extend the battery life.

To achieve this, Apple limits or turns off many of the background apps/tasks running on your iPhone. For instance, it disables email syncing, AirDrop, iCloud photos syncing, 5G connectivity, background refresh, Siri, automatic downloads, and more. It also reduces the screen brightness and the system animations.

By limiting all these tasks, your iPhone’s overall power consumption is significantly reduced, allowing the battery to last longer. Note, though, that the Low Power mode has little to do with the hardware. It’s mainly a software-level implementation.

Does iPhone Charge Faster on Low Power Mode?

From the test we did on an iPhone 15 and the thorough research we carried out online, we found that the Low Power mode does not affect iPhone’s charging speed. And even if it does, the impact is so minimal that it’s not even noticeable.

In our test, the iPhone 15 charged from 20% battery power to 100% a minute faster while in Low Power mode. Of course, this was probably due to other factors and not the Low Power mode—it’s worth noting that we had put the phone on Airplane mode during the charging test.

Therefore, we can conclude that an iPhone’s charging speed doesn’t increase on Low Power mode. The mode only limits background tasks and slightly reduces the CPU strain such that more power can go to the battery.

There won’t be a difference even if you charge your iPhone using the slow standard 5W Apple charger. The mode just affects other things that influence the battery life such as screen brightness, iCloud photos syncing, and 5G connectivity while the iPhone is discharging.

How to Charge Your iPhone Faster?

Battery-saving techniques such as turning your device off, enabling the Airplane mode, avoiding using the phone when charging and more can help your iPhone charge faster.

Avoid Using Your iPhone While Charging

Leave your iPhone alone while it’s charging. Don’t browse, visit social media, or check emails. Just avoid using it completely. Doing so will help quicken the charging process, hence increasing the charging speed.

This is equally crucial when it comes to safety, as using the phone while it charges can cause the battery to explode. Besides that, it causes the charger to work harder to fully charge your phone.

Switch off Your iPhone

Another way to increase the charge speed is turning off the device. Here are the steps to power off the device:

• Keep pressing the Volume+ and lock button until you see the slider to power off the device.
• Then drag the slider to right to turn off the device.

Enable the Airplane/Flight Mode

This Airplane Mode is also able to increase your phone’s charging speed. When you have this mode turned on, your phone will consume much less energy since most of its operation will get halted. Thus, it will charge quickly because it will concentrate only on charging. It will take a bit longer though compared to when you have the phone turned off.

Now, follow the steps below to enable the airplane mode:

• Open Settings on your iPhone.
• Find the Airplane Mode icon here and turn it on.

Use A Fast Charger

While it's common to use 3.5-volt chargers, we still recommend investing in 5.0-volts adapters because they are high-power fast-charging chargers that can reduce your charging time. These adapters are able to charge phones faster than many normal chargers.

Use A Wall Outlet Instead Of A USB Port

It’s easy and convenient to charge your phone via a USB port as you work on your computer. However, this method isn’t the most ideal since your phone may take much longer to fully charge as not much electrical voltage gets dissipated through the USB port. However, a wall charger dissipates higher electrical voltage hence connecting your phone directly to it will no doubt increase the charging speed.

What To Do When Your iPhone Won’t Charge?

There are times when an iPhone may fail to charge or even to come up when you turn it on. This could happen due to several reasons and the most common one is software issues which is what we will focus on here. If a phone has software issues, it’s very likely to start malfunctioning. It may not come up when you power it on, it may freeze, etc. While these problems might be overwhelming, the FoneGeek iOS System Recovery software offers the best solution.
