My answer to Does charging my iPhone 6 overnight destroy my battery?

Answer by Allen He:

Yes, we know, our smartphone batteries are bad as they barely last a day. At the earlier days when we buy it, it’s the fault of smartphone manufacturers. But what about several days later? It’s to some extent your own fault for charging it wrong this whole time. For example, charging phone overnight.

Firstly, let’s have a look at the following saying: charging phone overnight, or more specifically, charging phone when it’s already fully charged, will keep it in a high-stress, high-tension state, which will surely do wear down the battery with lasting damage at the same time.

So, is it true? Is charging phone overnight bad?

Well, you’d better ignore that. We couldn’t be more wrong.

And the truth is that Charging phone overnight will not harm your battery in the slightest. Any device with a Lithium Polymer battery must incorporate a charging circuit that will cut off charging power when the battery reaches 100%.

Besides, the smartphone battery is as smart as the phone itself. Apple, Samsung and all the top tech companies, almost of whose products use lithium-based batteries.
