Despite the new charger, the charging speed of the iPhone 17 is still behind the competitors

New tests conducted by the authoritative website “ChargerLAB” have challenged the charging performance of Apple’s new flagship, the iPhone 17, with the company’s various adapters. The results of this review show that Apple’s new 40W charger, contrary to expectations, does not significantly improve the charging speed of this device. This test was conducted in a controlled environment with a temperature of 25 degrees Celsius and using precision measuring equipment such as the POWER-Z KM003C tester and compared the performance of four official Apple adapters 20, 40, 70 and 140 watts. The obtained results clearly reveal the hardware limitations of this phone in terms of charging speed.

According to published data, when the iPhone 17 is connected to a 20W adapter, it takes 27 minutes to reach 50% charge and 52 minutes for 80%. It takes 1 hour and 50 minutes to fully charge the device. In this case, the phone with a voltage of 9 volts receives a power of about 19 watts for 36 minutes, and then the input power gradually decreases. But with the use of the new 40 W adapter, the situation changes a little. In this case, the device works with a voltage of 15 volts and achieves a maximum power of 36 watts. The time to reach 50% of charge is reduced to 19 minutes and 80% to 44 minutes, and full charging is done in 1 hour and 42 minutes.

The surprising thing here is that using more powerful 70 and 140 watt adapters gives almost the same results. With the 140W adapter, the full charge time is only one minute faster, 1 hour and 41 minutes. This proves that the iPhone 17 is not able to receive more than 36 watts of power, and the charging curve with the three adapters of 40, 70 and 140 watts almost coincides. Finally, the test showed that the new SPR AVS protocol in Apple’s 40W charger has no particular advantage for the iPhone 17, as the phone still uses the standard USB-C PD protocol. Therefore, users who seek The best Apple phone are, they should not expect a revolution in charging speed.
