According to Battery University, leaving your phone plugged in when it’s fully charged, like you might overnight, is bad for the battery in the long run.
Once your smartphone has reached 100 percent charge, it gets ‘trickle charges’ to keep it at 100 percent while plugged in.
Is it bad to leave your phone charging all night?
Don’t leave it charging overnight. That’s why you can plug your iPhone or Android phone into a charger, and revving it up to at least an 80% charge happens fairly quickly. But as we all know, our smartphone battery charges don’t last long.
Can you make your phone stop charging at 100?
The concept is that if you leave your phone on the charger for a while after it hits 100 percent, it will keep pumping in the current and that will reduce the capacity of the battery or even cause it to catch fire. This myth has some pretty legitimate origins, so it’s no surprise that it’s stuck around.
Should you charge your phone to 100?
For years, it’s been said that letting your phone charge all the way to 100% will result in the battery degrading faster compared to unplugging once it reaches 80% or so. According to Cadex (the world’s largest manufacturer of battery testing equipment), who should know, 50% to 80% is ideal for lithium batteries.
Do smartphones stop charging full?
Your phone will stop charging once the battery is full — but power will trickle in to keep it fully charged until you unplug it.
