Smartphones have become an inseparable part of our lives. We all use our smartphone until we fall asleep at night. We tend to leave it charging overnight. But is it safe to leave your smartphone charging overnight? The short answer to this question is yes, you can.

Is it a Myth?

The explosion of smartphones due to overcharging is a myth. There are lots of cases of smartphones exploding, but they usually result from faulty cheap batteries available in the market. If you use good batteries supplied by the manufacturer of the phone itself, then it is highly unlikely that you will face such issue. The infamous case of Note 7 that caused the explosion of batteries all over the world. The company admitted that the battery on that phone was faulty and they stopped its production.

There is a major reason that out smartphones are called smart, one of them being that it knows when it should stop charging. When your phone gets to 100% then it will stop the flow of current and thus saving the battery from being overcharged.

Most of the devices today including smartphones and laptops run on Lithium Ion batteries. They are rechargeable batteries with small memory effect. In the past batteries were made up of nickel. Nickel based batteries have cyclic memory and if they weren’t given full charges between cycles they tend to forget their full capacity. Many of us never used nickel-based batteries as the technology moved toward Lithium based batteries during the early 2000s.

“Contrary to what you might think (or have been told), leaving your phone or laptop plugged in all the time is not bad for its battery. ”
