Part 1: Is iPhone 15 Boot Loop a Serious Problem

If your iPhone 15 isn’t going beyond the Apple logo, it’s the boot loop problem. Your iPhone will restart but won't surpass the Apple logo as the device fails to boot properly. It’s a common problem that iPhone users face due to many reasons.

Most of the symptoms of the “iPhone 15 stuck on Apple logo” problem are related to the software end, such as installing 3rd party apps, malware, viruses, or even jailbreaking the device may lead to such a problem.

Part 2: [Basic 5 Ways] How to Fix iPhone 15 Boot Loop Quickly

Here are the 5 basic ways to quickly fix the iPhone 15 boot loop. Refer to the advanced method of this guide if none of these solutions fix the problem on your device.

Way 1: Checking for a Drained Battery and Ensuring Proper Charging

If your iPhone 15 is stuck in a boot loop, connect it to the charger and let it sit for 15 to 30 minutes. Sometimes, drained batteries can lead to the iPhone boot loop issue. The battery might not have enough power to boot the device properly. So whenever you turn it on, it reaches the Apple logo and turns off automatically, or it may get stuck.

Plug your iPhone 15 on a charge, and make sure it’s properly charging. If you’re using an old lighting cable, look for wear and tear on the cable. The damaged wire can’t interfere with the charging process.

Prefer using the Apple-recommended MFI-certified cables and charger for better battery charging performance. The aftermarket, non-certified iPhone accessories aren’t suitable and may damage the battery in the long run.
