Lithium batteries do not have a memory effect in a sense, but we must first understand that everything has a lifespan, and the memory effect of lithium batteries can be ignored in a sense, but we cannot say that there is no memory effect. at all. If you use You may experience the performance degradation of lithium battery through laptop. You can fully discharge the battery after using it for a while (it will automatically turn off during normal use), then fully charging it 2-3 times can restore the battery's power performance.
Is it better to charge the cell phone battery when it has the last bar left or when it is exhausted?

Will recharging the exhausted cell phone lithium battery help extend its life? (If you understand, learn the principles)
Charge well, too much empty energy has a great impact on the battery. 1. Lithium-ion batteries have a long service life. Lithium-ion batteries
are limited in the number of times they can be charged, but at the same time, lithium-ion batteries, like everything else, also have a limited lifespan

.
2. Do not let the device completely run out of power. If the lithium-ion battery charge is too low, it may permanently damage the lithium-ion battery. So you can plug it in and charge it whenever it suits you
as much as possiblewheat.
3. Lithium-ion batteries will not be overcharged and are protected by internal circuitry.
4. The biggest fear of lithium-ion batteries is the problem of excessive temperature.
Temperatures above 40 degrees will reduce the ability of lithium-ion batteries to be charged.
4. p>
of power.
Try to use the cell phone battery until it indicates low battery before recharging (it can be charged three times). This can better activate its potential ability, but remember to charge it immediately when the time is up. The battery shows that it is low, the battery cannot be lower than its protection voltage, otherwise it will not be charged no matter how long it charges, so you can only remove the battery and use a universal charger to activate it, then charge it again.
