iPhone 16 Pro Max MagSafe Charging Too Slow? 5 Potential Causes and Solutions

MagSafe technology was introduced to provide iPhone users with a seamless and efficient wireless charging experience. However, many iPhone 16 Pro Max owners have encountered an issue where MagSafe charging is significantly slower than expected.

Despite Apple’s claims that MagSafe delivers up to 15W of power, users have reported inconsistent results. So, what’s causing these slow MagSafe charging issues? In this blog, we’ll talk about the iPhone 16 Pro Max MagSafe charging too slow and provide actionable solutions to help you charge faster and more efficiently again.

Multiple issues have been associated with the premium iPhone 16 Pro Max, including ‘extremely slow’ MagSafe charging performance. The unusually slow MagSafe charging issue didn’t happen immediately. It happened when using the same MagSafe charger twice on the iPhone 16 Pro Max, with the first instance charging as intended and the second barely charging the phone at all.

Speculations of older MagSafe chargers used on the new iPhone 16 Pro Max and Apple’s new MagSafe ecosystem, which is Qi2 certified, were pointed out as the likely causes. Perhaps a MagSafe phone case is causing the slow charging issue, or the iPhone itself is failing.

“Sometimes, the phone barely charges. Sometimes, it works flawlessly. It’s pretty random.” One user stated and included a proof of this mind-boggling problem, which we attached below:

Another specific issue we’ve heard of is the slow MagSafe charging using the Anker MagGo 3-in-1 Qi2 certified charging station, which previously charged the iPhone 15 Pro Max to 100% overnight, now only charges the iPhone 16 Pro Max to approximately 65-70% in the same timeframe.

This wasn’t an isolated case. According to the Reddit thread we linked above, other users experienced the same thing. Some have the same slow charging issue, but this time, their phone’s interface becomes unresponsive, which is then solved by a reboot.

In the next section, we’ll discuss the potential causes and solutions to address the iPhone 16 Pro Max MagSafe charging too slow issue. Continue reading below.

The cause of slow MagSafe charging can be attributed to various factors. In the following sections, we’ll explore the common reasons behind slow MagSafe charging and provide practical solutions to help you maximize your iPhone 16 Pro Max’s wireless charging experience.

Using non-MagSafe-compatible or particularly thick cases can interfere with the magnetic alignment necessary for efficient charging. Misalignment due to incompatible cases can reduce charging speeds or even prevent charging altogether.

First, your iPhone case should be MagSafe-compatible, like our iPhone 16 Pro Max aramid fiber case. This case is not simply made of the five times stronger than steel 600D aramid fiber. It’s also MagSafe-compatible, making it the perfect iPhone 16 Pro Max case.

Always remember to choose cases designed to align perfectly with MagSafe chargers to facilitate optimal charging speeds. If you’re unsure about your case’s compatibility, try removing it during charging to see if there’s an improvement in charging speed.

Improper alignment between the iPhone and the MagSafe charger or using non-certified chargers can significantly reduce charging efficiency. MagSafe technology relies on precise alignment to deliver optimal power, and uncertified chargers may not meet the standards for efficient charging.

To eliminate this alignment and incompatibility problem, use only certified MagSafe or Qi2 chargers to ensure compatibility and safety. When placing your iPhone on the charger, ensure it’s properly aligned; the magnets should guide it into the correct position. Using certified chargers and ensuring proper alignment can greatly enhance charging performance.

The Optimized Battery Charging feature is designed to prolong your battery’s lifespan by learning your charging routine and delaying full charges. While beneficial for battery health, this feature can result in slower charging times, especially if your charging habits are inconsistent.

Consider disabling this feature if you consistently need your iPhone to charge fully and quickly. To do this:

Step 1: Navigate to Settings.

Step 2: Go to Battery.

Step 3: Tap on Battery Health & Charging.

Step 4: Toggle off Optimized Battery Charging.

Keep in mind that while this may speed up charging, it could potentially affect long-term battery health.

High temperatures can cause your iPhone to slow down charging speeds to protect the battery from overheating. Charging generates heat; if your device becomes too warm, it will automatically reduce charging speed as a safety measure.

To solve the temperature regulation issue, charge your iPhone in a cool, well-ventilated environment. Avoid using the device during charging, as this can generate additional heat. If you notice your iPhone becoming warm while charging, consider removing it from its case to allow better heat dissipation.

Using low-power adapters may not provide sufficient energy for efficient charging. For instance, a wireless charger that offers less than 10W can result in slower charging times.

Opt for a higher wattage power adapter compatible with your MagSafe charger. Apple recommends using a 20W or higher USB-C power adapter with MagSafe to achieve optimal charging speeds. Make sure that both the charger and the power adapter can deliver the necessary power for efficient charging.

Slow MagSafe charging with your iPhone 16 Pro Max is a hassle, especially when you rely on fast wireless charging to get your day going. Maybe it’s time to stop and understand the potential causes that can help you find the solutions. Remember, maintaining optimal charging practices improves charging speed and contributes to the longevity of your iPhone’s battery.
