Introduction

About a month ago, shortly after the release of the iPhone 15 series, we purchased the iPhone 15 Pro Max and conducted a ChargerLAB compatibility 100 test video. The results demonstrated its consistent and excellent compatibility. Since then, many people have left comments on our YouTube and official website, expressing their interest in seeing the charging compatibility of the base model, the iPhone 15. Therefore, today, we will examine whether its compatibility matches that of the Pro Max.

Charging Compatibility Test

Next, ChargerLAB will conduct a comprehensive test on the compatibility of the iPhone 15, evaluating its performance with a selection of more than 100 charging devices. These devices include Apple chargers, third-party chargers, power banks, and portable power stations, aiming to cover the majority of users' charging scenarios.

Apple Chargers

First, let's take the Apple 30W charger (model: A2164) as an example. ChargerLAB POWER-Z KM003C shows that it can deliver 8.44V 2.39A, equivalent to 20.16W of power to the iPhone 15.

Actually, that represents a huge step back from the previous generation, which could reach up to 25W!

We tested all the Apple fast chargers we have.And we can see that just like the 15 Pro Max's test, only the 29W one reaches a power of more than 20W with relatively high voltage and low current, while the others are at the 9V2A level.

Create a bar chart to visualize the tested charging power. It's evident that almost all chargers consistently hover around the 20W level. For chargers with an output power of 30W or more, the bottleneck is the phone's charging strategy, while for those with a maximum output power of 20W or less, the bottleneck is the charger's own maximum output power.

Third-Party Chargers

Moving on to third-party chargers. First, we want to emphasize a point that wasn't mentioned in the previous test of the iPhone 15 Pro Max. The iPhone 15 series has specific pin requirements for USB-A to USB-C charging cables, and even cables from the same batch may experience charging issues. We may address this issue in a future video, so stay tuned!

For now, in this test, we are only assessing the charging compatibility performance of third-party chargers when paired with USB-C to USB-C cables (with some margin of error).

Next, let's take the AOHi 140W charger (model: AOC-C012) as an example. It can deliver 8.67V 2.24A, equivalent to 19.41W of power to the iPhone 15.

Summarizing the data into a table, it's evident that all of them trigger 9V2A, and the special 15V condition of Apple's 29W charger doesn't appear. This is because Apple's 29W charger has a unique PDO, which is 14.5V2A.

Plotting the data into a bar graph, we can see that this time, the charging power of the iPhone 15 also stays at the 20W level. However, the HONOR 65W charger is an exception, consistently delivering only 17W, ranking at the bottom.

Power Banks

Next up, let's take a look at the power banks. All the tested devices trigger 9V2A, including the IDMIX Magnetic 10000mAh, which had only 5V2A in the previous test of the 15 Pro Max.

Once again, plotting the data into a bar graph, the power output remains around 20W. So, power banks that support the PD 9V2A level can meet the iPhone 15's charging needs.

Power Stations

Lastly, we have power stations. These devices generally have 60W/100W USB output ports. As expected, all the devices tested triggered the 9V level, with no 5V level detected.

Plotting the data into a bar graph, the iPhone 15's charging power remains around 20W, showing no significant variation when compared to other chargers, and power banks.

Summary of ChargerLAB

In brief, the iPhone 15 performs well when paired with both Apple's charger and third-party chargers rated at 20W or higher. It consistently achieves a maximum charging power of around 20W, showcasing excellent charging compatibility, as always. However, it falls behind some Android competitors that offer faster charging speeds, such as 45W, 100W, or even 200W. We hope that Apple addresses this limitation in future generations to meet users' expectations.

However, the new USB-C port makes charging and data transfer more convenient. It also enhances the compatibility of third-party chargers, cables, and docks, extending their lifespan. In conclusion, the iPhone 15 successfully passed the ChargerLAB Compatibility 100 Test. Below is the compatibility 100 test report issued by us.
