40W Fast Charging degrades the Smartphone Battery faster, Oppo warns

Oppo Super VOOC Charging

Oppo has taken its charging technology to the next level with the launch of a phone with 65W fast charging support. The company launched the Ace2 smartphone back in April. The phone launched with a 90Hz screen, the Snapdragon 865 chip, and an in-screen fingerprint sensor. However, one of the most intriguing specs of the Ace2 remains its charging speed.

The phone is powered by a 4,000mAh battery with support for 65W wired fast charging and 40W wireless charging. This may seem like all you need, but it is not exactly an absolutely perfect solution.

Oppo has confirmed that its 40W fast charging technology has a negative effect on battery life. In fact, the company revealed that 40W fast charging degrades battery life to 70% in the same cycles that 15W charging would degrade it to 90%. This may just be the reason some OEMs like Apple and Google have not been after the big charging speed numbers.

According to some manufacturers, in fact, 15W charging speed is sufficient for most people in any case. Even though fast charging enables smartphones to charge faster, it comes at a cost. Your phone charges faster but the battery life also depreciates faster.

Since many people do not use their phones for more than three years, it may not be so easy to notice the change. However, it is still worth noting that fast charging comes at a cost.

In order to tackle this to an extent, some smartphone manufacturers are slowing charging after about 50%. However, it is still interesting to note that upcoming devices from Oppo and other BBK Electronics brands (which include Vivo, OnePlus, and Realme) will still support 65W fast charging.

Would you be willing to sacrifice battery life for fast charging? Let us know your thoughts in the Comments section below.
