Fast charging is a feature that has been exclusive to high-end phones until this year, but we are now seeing the same trickle down to affordable phones. Of course, the fast charging on flagships is now a lot faster (going all the way up to 40W), but you easily get 15W, 18W and 20W fast charging on affordable phones priced under 20K, spread across standards like VOOC, Qualcomm Quick Charge 3.0 and 4.0, and Samsung’s Adaptive fast charging.

Advantages and disadvantages of fast charging

Fast charging is a matter of convenience, having tasted which, you wouldn’t want to go back. Charging gadgets by itself is a pain that most people would want to avoid altogether if they could, and fast charging lets you get done with the process quickly. It can also be a lifesaver in situations when you forget to top up your phone and are scrambling for charging points last minute.

On the downside, to implement fast charging, the separator within the battery needs to be thicker, consequently inflating the size of your phone and battery. Fast charging also has an impact on your phone’s battery health in the long run, but not as much to be a deal-breaker.

But is fast charging a must-have? If you are buying a phone today, we’d recommend you at least gun for 15W fast charging support.
