iPhone 15 Charging Anomaly: 27W Feels Hotter Than 100W

In our assessment of iPhone 15 Charging, a notable concern emerged with the iPhone 15 Plus—unexpectedly high temperatures during charging. This prompted a thorough investigation into the underlying reasons for this unexpected behavior.

iPhone 15 Charging:Temperature Surprises

Tech expert Xiao Heipang’s tests revealed the iPhone 15 Plus, with its 27-watt charging, got hotter than some 100-watt Androids. Initial dismissal of the problem changed due to increasing user complaints, prompting us to reevaluate with more extensive tests.

The results were startling. Despite its slow 27-watt charging, the iPhone 15 Plus hit a peak temperature of 52.59°C and stayed at 45°C for almost 25 minutes, beyond safe battery limits.

iPhone 15 Charging(Pro): A Milder, Yet Warm Encounter

Looking at the iPhone 15 Pro, limiting its charging power to 20 watts to prevent overheating didn’t fully solve the issue. Its temperature still peaked at 48.59°C during charging, challenging the idea that Apple’s caution is just for battery protection.

iPhone 15 Charging Comparisons with Competitors

To understand Apple’s charging performance, we compared it with Realme GT5 and Redmi K60 Ultra, both claiming higher charging capacities. Realme GT5 briefly hit 200 watts, reaching 45.3°C. Redmi K60 Ultra at 120 watts stayed at 46.6°C.

This comparison raised questions about the effectiveness of Apple’s approach compared to its Android counterparts.

The Unveiled Mystery

Digging deeper, we aimed to unravel the mystery—battery quality or charging technology? Rumors of a cheap battery were debunked. Our investigation suggests Apple’s choice of charging technology, possibly a traditional DC step-down chip, is a key factor.

Looking Forward

As user complaints persist and speculation swirls, the exact charging chip in the iPhone 15 remains a secret due to Apple’s confidentiality policy. Until revealed, the iPhone’s charging capabilities may continue lagging behind. Enthusiastically waiting for Apple to bridge the gap in fast-charging technology, freeing users from the frustration of extended charging times.
