In September 2017, Apple unveiled its latest flagship phone “iPhone X” with some top notch tech features, one of which is the wireless charging technology. But then, is wireless charging good for your iPhone?.
Being a new technology, we have had plenty of reasons to believe that Apple’s implementation of wireless charging would be superior to the technology employed by its rivals like Samsung but new evidence probably just proved otherwise.
According to Apple, iPhone’s “battery is designed to retain up to 80% of its original capacity at 500 complete charge cycles” beyond which point the Li-Ion battery pack is considered worn and should be showing signs of degradation.
Each user’s personal experience with their batteries will vary depending on factors including how often they use their iPhone and ultimately how often it requires a power-up.
As a general rule of thumb, users should know that as their battery ages it won’t last as long as it did fresh out of the box, and so your recharge frequency is going to increase, accordingly.
Does Wireless Charging Damage iPhone Batteries?
Back in January, Adrian Kingsley-Hughes ZDNet blogger figured out wireless charging might not be good for the health of his iPhone with time. He observed his device reached 90 recharge cycle in just four months of wireless charging and 135 cycles barely just six weeks after.
Utilizing the macOS-based iPhone battery monitoring app, CoconutBattery, Kingsley-Hughes suggested that at this rate he expects to hit 150 charge cycles by the six-month mark.
“That means that in 18 months I should be at 450 recharge cycles, and will break the 500 mark after another two months,” he said. He previously “would have expected an iPhone to make it closer to the 36-month/three-year mark before hitting the 500 recharge cycle.”
Kingsley-Hughes conceded that he considers himself an iPhone power user and that when he’s not using the device it’s generally left on the wireless charger for convenience. Previously, he would have plugged a Lightning cable into it like the rest of us.
“The issue is that when the iPhone is being charged using a cable, the phone is being powered by the cord (there is some load on the battery, but it’s minimal) but when using wireless charging, the battery is what’s powering the iPhone, with the wireless charger only being used to top up the battery.”
In other words, his battery isn’t getting a break and appears to be burning through recharge cycles at a much faster rate due to switching from the cable to a wireless charger.
“I’m switching back to cable charging” he continued, adding that “the idea that my battery could be trash in under two years is frankly worrying.”
If you’re an iPhone 8, 8 Plus or iPhone X user who utilizes wireless charging like Kingsley-Hughes, you may want to consider switching back to the standard Lightning cable, at least to experiment a bit and see whether you’re encountering the same issues.
