Part 1: Why Isn't My iPhone 15 Pro Max Charging?
Why is my iPhone 15 Pro Max not charging? This is a valid question because the correct answer leads to the right solution. The most probable reasons for the iPhone 15 not charging are either a faulty charging cable, faulty power outlet, charging port, or software glitches.
- Faulty charging cable: A faulty or low-quality third-party charging cable is the most common reason the iPhone 15 won't charge. We highly encourage you to use the original charging cable, which keeps your phone charging and working great.
- Faulty Power Outlet: When investigating why my iPhone 15 Pro Max is not charging, I must check my power outlet. A faulty power outlet or a burnt wire can also affect your phone's charging.
- Charging Port: Another common cause of iPhone 15 not charging is a faulty or dusty charging port. Sometimes dust settles in your iPhone's charging port, and since you cannot easily reach it, the dust can accumulate, and your iPhone 15 won't charge.
- Software Glitches: Apple devices are generally very robust and bug-free. However, some malware can still sneak in through third-party apps. When this happens, your iPhone’s charging can be affected.
Part 2: How to Fix iPhone 15 Pro Max Not Charging?
Method 1: Check the Basics
As we discussed in the reasons why my iPhone 15 pro max is not charging, simple basic stuff is usually the cause you can fix quickly. You can start by inspecting the charging cable and adapter, checking the charging port, and ensuring the proper power source is used.
Use Another Power Source
When your iPhone 15 does not charge when plugged in, you can use an alternate power source, another wall socket, or another wall outlet to ensure that the issue is not with the phone.
Change Your Charging Cable
Your charging cable may wear out and become faulty due to extensive use. Sometimes, you can see the cut, while other times, the damage is inside, and you may not notice. Also, if you are using a third-party app, your iPhone may not charge. So, getting a new original charging cable, ESR cable, or PD charger can fix the iPhone 15 not charging issue.

Sometimes, dirt can accumulate in the charging port and block it. If your iPhone is not charging, there are two ways to fix this issue. You can either try cleaning it yourself or consult a professional.
You can try to clean your charging port using a clean paper towel, cleaning liquid (e.g., without alcohol), and a tiny sharp object like a wooden toothpick. Now, wrap the paper towel around the toothpick and carefully scrape the port.
