Does ‘Fast Charging’ Really Ruin Your Phone Battery? Experts Weigh In.

You knew it was bound to happen. In our fast-paced world, the desire to charge a smartphone even faster has led to some super fast charging options. Now, instead of weighing the pros and cons of leaving your phone on its charger all night long, or trying to figure out when in the day you’ll have a free hour to charge your phone and not use it (answer: never), you can just plug it into one of the latest and greatest faster chargers and, minutes later, you have yourself a fully charged battery. 

But is there a downside to fast charging? And can it have a negative effect on your battery when all is said and done? Here’s what tech experts have to say.

The biggest worry about fast charging is that it will cause your phone to overheat because it’s being powered up rapidly. As we know, extreme heat or cold is one major cause of battery degradation. 

But here’s why you needn’t worry about fast charging and your battery: the lithium-ion battery that’s powering your iPhone or Android today is NOT the same version of the battery that caused these worries several years ago when you’d hear of so-and-so’s phone exploding from overheating.
