Since the end of 2018, some smartphones have been compatible with a technology called “ultra-fast charging”. By using chargers much more powerful than before, manufacturers are trying to drastically reduce the charging time of our smartphones.
The most powerful chargers today are Oppo’s (65W), but brands like Xiaomi and Vivo seem determined, in the near future, to go further with models exceeding 100W. This ranking is therefore likely to be regularly upset over the course of smartphone launches.
At the 01net.com lab, we measure the recharge time of all the devices we receive. To ensure that our results correspond to reality, we charge a smartphone to 100% when it arrives and then we completely discharge its battery. Once it reaches 0%, we plug it into its original charger and use little software to measure its remaining battery capacity at regular intervals. You will see in this top 10 that Chinese brands are particularly ahead of this technology and occupy all the places in this ranking.
Is this technology dangerous?
Before presenting our results to you, it seems important to us to discuss the doubts that some may have about the potential dangerousness of such a technology. While it is proven that batteries age less well when they heat up a lot, it is still too early to determine the impact of super fast charging on the lifespan of our smartphones. Note also that some manufacturers like Oppo and Realme use two batteries in their devices to reduce the heating temperature during recharging. By dividing the energy received in two, the smartphone retains normal heat and therefore does not suffer from the high power of its charger (it remains at low voltage). Our thermal camera confirms that, in some cases, ultra-fast recharging causes the batteries to heat less than conventional recharging.
