Apple’s newest iPhones – the iPhone 8, iPhone 8 Plus and iPhone X – have been found to charge slower than rival smartphones running Google’s Android operating system. The iPhone X and iPhone 8 both lag behind competition despite supporting the new fast charging technology based on the USB Type-C standard.
In a test comparing charging time of leading smartphones, the iPhone X, iPhone 8 and iPhone 8 Plus charged slower than the OnePlus 5T and LG V30. Tom’s Guide tested these devices by charging from zero and measuring the battery percentage after 30 minutes and one hour of charging time. While all the major Android smartphones come bundled with fast charging adapters, iPhone users need to buy a separate 29-watt power adapter and USB-C to lightning cable, which retails for a combined price of around $68.
The first test measured the battery percentage of these smartphones in 30 minutes of charging with their included adapters. In the case of the iPhones, both the standard AC plug and the separate fast charging adapter were used to precisely conclude the charging time. During the test, the phones were on but the screens were turned off.
The OnePlus 5T, which relies on its own proprietary Dash Charge technology, emerged as the clear winner by reaching 59 percent charge in just 30 minutes. The OnePlus 5T comes bundled with a 20W power adapter that delivers higher amperage of current and uses a dedicated circuit within the charger for heat management. OnePlus 5T was followed by LG V30, which reached 53 percent in 30 minutes.
They were followed by Apple’s iPhone X, iPhone 8 and iPhone 8 Plus with 50 percent, 49 percent and 47 percent battery in 30 minutes of charging with the $68 fast-charging adapter and USB-C to lightning cable. The charging time was relatively slower when charged with the included adapter with iPhone X reaching just 17 percent after 30 minutes. The iPhone 8 and iPhone 8 Plus managed 30 percent and 26 percent respectively with their included adapters.
OnePlus 5T reached a commendable 93 percent battery after one hour of charging while LG V30 managed 86 percent. After 60 minutes of charging, the iPhone X, iPhone 8 and iPhone 8 Plus were at 81 percent, 80 percent and 79 percent respectively while charging over fast charging adapter. Google Pixel 2 and Samsung Galaxy Note 8, which rely on Qualcomm Quick Charge, managed to reach 38 percent and 35 percent respectively after 30 minutes. The smartphones hit 75 percent and 74 percent mark after one hour of charging.
With the bundled adapter, Apple iPhone 8, iPhone 8 Plus and iPhone X hit 58 percent, 55 percent and 37 percent respectively after charging for an hour. The test highlights the strength of OnePlus’ Dash Charge technology but it also makes it clear that iPhone users will be better off buying the separate adapter and cable for fast charging their iDevice. Apple should have ideally included them in the box but the company makes healthy profits by selling key accessories separately in its stores and online retail channels.
