I remember the guy at my phone store talking about this in passing, but I thought better of it. Was Phone Store Guy right?
We all do it, but they're saying it's not good for your phone. Charging it overnight.
According to some tech experts, ZDnet, it's bad for your battery to charge your phone all night.
Even though modern phones charge smarter than they used to, they're still keeping the battery warmer than room temperature, and over time damages your battery.
To max out your battery's life, they say do it this way:
Charge it for about 30 minutes or so in the morning when you wake up.
Then charge it for another 30 minutes or so in the afternoon to get it around 80%.
Hence, your phone is spending less than two hours a day getting charged, which is a lot less time than if you charge it overnight.
Now, to counter that argument, PCMag.com says that's a myth about the over-heated phone. Your phone stops charging when it hits 100%, but they do say that over time, the battery will wear if left charging overnight.
Their advice: Plug the phone in or place it on the wireless charger when you go to sleep. If you wake up in the night, unplug it or move it to prevent constant trickle-charging.
So, maybe they agree that the fully-charged overnight thing, in the long run, may wear your battery out faster.
