Part 1: Why My iPhone 15 Keep Lagging?

There can be multiple reasons behind the new iPhone 15 lagging. Here are the most common obstacles affecting the performance of your device:

Low Storage Space

The closer your iPhone gets to maxing out its storage space, the slower it becomes. This is because your device requires standard free space to operate with any bumps. Lack of significant storage space can make your iPhone 15 laggy.

Outdated Software

The presence of outdated software on your iPhone can make it hard for your device to manage new apps and features effectively. This is another likely answer to your question, “Why is my iPhone 15 freezing and lagging?” Thus, it’s integral to frequently update the iPhone 15 software for optimal functionality.

Too Many Apps Running in the Background

Heaps of apps running in the background can result in iPhone 15 lagging. Your iPhone’s processor allocated power to all the apps, even those open in the background. The greater the number of apps, the harder for the processor to juggle power between them. This eventually leads to the iPhone lagging when typing or performing other tasks.

Old Hardware

The more you use your iPhone 15, its hardware will become older, making it hard to manage new apps and features. When this happens, your device will start slowing down or become unresponsive.

Environmental Factors

Extreme temperatures on the higher and lower ends of the scale can cause the iPhone 15 to slow down. In such circumstances, your device tries to regulate its temperatures, taking away resources from additional tasks. Thus, keeping your device at moderate temperatures is crucial to prevent performance issues.
