Unleash the Power: Is Low Power Mode the Hidden Thief of iPhone Speed?

Key Points:

• Low Power Mode was introduced in iOS 9 in 2015 and reduces power consumption by turning off or reducing various hardware and software features.
• Low Power Mode can be enabled manually or automatically when the battery level falls below 20%.
• The feature reduces display brightness, performance, and visual effects, and may slow down your iPhone.

As a tech journalist, I’ve noticed that some users often face slow performance issues with their brand-new iPhones.screenshots or videos showing that Low Power Mode is on. As it turns out, this feature can significantly impact iPhone performance. Let’s dive in to understand how Low Power Mode works and its effects on your device.

How it works:

When enabled, Low Power Mode reduces power consumption by turning off or reducing various software and hardware features. Apple describes it as a way to extend battery life in situations where charging might not be possible for a while. The feature can be enabled manually or automatically when the battery level falls below 20%.

What does it change on your iPhone?

According to Apple, Low Power Mode:

• Turns off or reduces 5G on compatible devices
• Sets Auto-Lock to 30 seconds
• Reduces display brightness and limits the refresh rate to 60Hz on devices with ProMotion
• Turns off Always-On Display on compatible iPhones
• Reduces visual effects
• Pauses background activities, such as downloads, iCloud sync, backup, and email fetch

Does it slow down your iPhone?

Yes, it does. Apple doesn’t mention performance in the official list, but Low Power Mode also reduces the use of the device’s performance cores, relying more heavily on the efficiency cores. This can result in significant performance degradation.

Benchmark tests:

To illustrate the impact, I ran a benchmark test using GeekBench 6 on an iPhone 16 Pro Max with and without Low Power Mode:

• Without Low Power Mode: Single-core score: 3341, Multi-core score: 8270
• With Low Power Mode: Single-core score: 1384, Multi-core score: 4093

The results demonstrate that the device runs at roughly half its performance with Low Power Mode enabled.

Conclusion:

It’s essential to use Low Power Mode strategically, as it’s more effective in reducing battery consumption in standby mode but less so when actively using the phone. If you only need it in certain situations, enable it when necessary, but be aware of the potential performance impact. The good news is that Low Power Mode is also available on iPad, Mac, and Apple Watch.
