New chargers for mobile devices have appeared on the market with capacities of 18, 36, 50, 65, and even 100 Watts! Naturally, buyers have a question – does fast charging kill a smartphone battery or not.
Quick and accurate answer – NO!
Fast charging does not damage the battery of mobile devices. And this is great news. But not for everyone. Because this statement applies only to certified Quick Charge chargers. Fortunately, counterfeits on the market are becoming less common, as most smartphone manufacturers offer branded chargers for their devices.
Does fast charging kill a smartphone battery?
The question itself cannot be called foolish. After all, at the dawn of mobile devices based on Windows Mobile and early versions of Android, there were problems. You can still find photos online of swollen or torn batteries that simply could not withstand increased current. But the situation changed fundamentally when Apple decided to implement fast charging technology in their phones. Other brands quickly followed suit. The result – recent statements from Chinese manufacturers about a 100 Watt power supply.
All the credit for answering the main question (Does fast charging kill a smartphone battery?) can be given to OPPO. The well-known mobile device manufacturer conducted laboratory tests and officially announced their results worldwide. The studies showed that even after 800 charge and discharge cycles, the smartphone’s battery retained its capacity. And its efficiency (in terms of time) remained unchanged. That is, the owner can expect two years of active phone use.
The testing involved OPPO smartphones with a 4000 mAh battery and a SuperVOOC 2.0 charger with a capacity of 65 W. How other smartphones’ batteries will perform is unknown, as technologies differ slightly among brands. But it can be said with certainty that representatives of the mid-range and premium segments will not disappoint us.
