Why should we recharge our batteries before they hit 0% for a better durability ?

The unhealthiest state for a battery is 100% but also 0% because quite Literally all the electrons are on one side…that is quite the uneven state… the way a battery works in general is you move electrons from one side to the other electrode so ideally you want to avoid those uneven states.
If you have that happen, over time crystallisation can happen, making battery cells unusable and even making them bloat and prone to exploding
The healthiest state for a lithium ion battery to be in is somewhere around 50% which is why you also find your new phone somewhere around 50% charge in the storage when u buy it.. or a bit less because the battery after all drains with time…this is no accident, really more a measure to keep the battery safe in storage for longer.
Many companies tend to have protective mechanism there. Some give features that prevent your phone from reaching those too high or too low areas. Others just plain do it and not tell you. Meaning your 100% and 0% isn’t exactly the truth.
It is similar to the saying that the last 20% of progress need 80% of the work.
Imagine a battery like a sponge.
A sponge is easily taken from soaking to slightly wet . But if you want to completely dry it until there is no water whatsoever it is a harder task.
Same with a battery. Draining the last percentages of energy from one side puts immense strain on the battery.
Well I’ve been charging my batteries all wrong then. If this is the case, when is the best percentage to charge a battery?
Because, if you don’t the phone will turn off and you will have to wait for the phone to charge a little before you can turn it back on and use it plugged in.
Depending on the battery and device, 0% may not actually be 0%, likewise 100% may not be 100%. Many modern devices with lithium batteries have protection logic that keeps the battery in the 10-90% charge range during normal use and just lies to the OS or user about how much charge there is.
Going outside of this range can permanently damage a lithium battery, so there’s a good reason for this deception.
A device left in storage for a long time can actually hit 0% through gradual internal drain and will often not function or charge properly afterwards.
If you don’t, the phone will shut off and you’ll need to give it a little time to charge before you can use it while plugged in.
