Is the 40 80 Battery rule real?

Is it OK to leave phone charging overnight?
Make sure you unplug it from the charger after it reaches 100%. 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.
Is Fast charging bad?

Should you charge your iPhone at 100 percent?
Apple recommends, as do many others, that you try to keep an iPhone battery between 40 and 80 percent charged. Topping up to 100 percent isn’t optimal, although it won’t necessarily damage your battery, but letting it regularly run down to 0 percent can prematurely lead to a battery’s demise.

At what percentage should I charge my phone?
Most Smartphones have a lithium-ion battery that lives longer when charged regularly. Unlike the nickel batteries used in older phones, lithium-ion batteries do best when kept above a 50 percent charge. Repeatedly allowing the battery to drain fully may shorten its life and decrease its overall capacity.
Why you should not charge your phone to 100?
When your phone hits 100%, it stops charging. As the battery drops to 99% and beyond, sometimes a “trickle charge” kicks in to bring your phone back to 100%. This constant trickle stresses your phone battery, leading to increased heat (ya know how your phone feels hot?) that, as we now know, wears out the battery.
Is it dangerous to use phone while charging?
There is no danger in using your phone while it’s charging. This myth comes from fears about batteries overheating. Lithium-ion batteries can be dangerous if they have any type of manufacturing defect, but this is rare. … Also, charging from a wall plug is always faster than using a computer or car charger.
