Should I charge overnight with 60% battery?

My iPhone 14 Pro Max gets to the end of the day with 60% battery left. Should I still charge it overnight every night, or leave it for the next day, risking going below 20% and/or making it harder for the Optimised Battery Charging to adjust to my routine?

iPhone 14 Pro Max, iOS 16

Hello!

When the phone is fully charged, it is no longer accepting power until the phone drops below 100%. If the phone is in sleep mode and idle all night, it should only accept minimal levels of power. Modern smartphones are very clever with charging nowadays.


iPhones have multiple features which can extend battery lifespan in regards to overnight charging. There's "Optimized Battery Charging", which will learn your routine so that the phone will only charge to 80%, then stop, then finish charging closer to when you wake up.

Another cool feature that limits how much the phone charges at night is "Clean Energy Charging", which only accepts power when the energy from your local power grid is "clean".

You could totally leave it overnight if you want to, the phone is easily a 2 day phone in my experience. That would probably be the "healthier" option for the battery, as charging produces heat, and heat is bad for batteries.

However you probably don't need to worry about charging overnight or not, because the battery should last multiple years just fine with normal usage, and it can be replaced.

That is completely, totally, utterly NOT TRUE. Using Optimized Battery Charging and charging at night, EVERY night will NEVER hurt the battery on iPhone.


You suggest it's common logic. It is NOT. Maybe you should read on it --> When to charge your iPhone or iPad - Apple Community
