Some people say that leaving the phone and laptop charged overnight will damage the battery.
I can tell you that I left my device to charge continuously overnight or all the time and never noticed a problem with the Battery.
Should the phone, laptop be charged overnight or not.
The short answer to this is that you can charge your devices overnight as long as you use a charger that has automatic shutoff to avoid overcharging.
Virtually any brand name charger that comes with a device from the factory must have an automatic circuit breaker built in and third-party chargers sold by reputable companies.
That being said, I advise you to avoid cheap “nameless” and “knockoff” chargers that are sold in nonspecific stores and many less reputable websites as they actually can. damage to the device’s battery (and worse).
The “nameless” charger is just that. They usually won’t have a brand name printed anywhere on the package or on the chargers.
“Counterfeit” chargers are branded with names like Apple, Samsung or Motorola, but they are usually sold by third-party sellers at low prices.
Many “unnamed” and “knockoff” chargers are poorly designed and sloppy built. Some have been known to not only damage batteries, but also cause fire and electric shock. In Vietnam, there are often fake products originating from China
As a general rule, you can always trust a charger if it came with the device from the manufacturer. And you can trust a third-party charger as long as it has automatic shut-off and it’s sold by a reputable company.
