Can I Charge My Phone Overnight?

Monday, May 4th, 2015 by | Filed Under: Quick Tips

Is it okay to leave your phone plugged into charge overnight? Harry from Canton, MI wants to know and he’s not the only person who’s asked that question recently.


You may have heard that it’s a bad idea to leave your phone plugged in overnight, but truthfully it shouldn’t be an issue. Your phone is smart enough to know when to stop charging once the battery is full and overnight is the one time you don’t need your phone.

You do waste a minimal amount of electricity, but it’s not going to bankrupt you. The total would probably be less than $1 per year. I would advise making sure that you have the charger plugged into a surge protector. I’m paranoid about power surges and electronics.

    Before I got a smartphone, I had Nokia cell phone, which I used to charge overnight everyday. After about a year the battery swelled and the lid came off. The repair man told me that due to overcharging the battery swelled and was unusable. I had to replace the battery. I wonder whether this is also applicable to the battery in the new Samsung Galaxy phone. So I do not charge it overnight.
    Further, I am told that it is not wise to wait until the battery completely drains off and also not to charge it full. For longer life of battery, charge it when 20% charge is remaining and then charge up to about 80 % and I am following that.
