I have a new tablet or my very first and I read something that you should never charge the battery over 95%, because otherwise the battery would lose capacity more quickly. Is that true or are you charging your cell phones, tablets, notebooks all the way?
Full to the limit, empty to the limit, every atom in the cell should have something to do.
that plays a rather subordinate role. The number of charging cycles is limited, so only charge your tablet when it is empty and not at 60%
You should never let your device run completely empty, this is not particularly good for the battery. Fully charging it is not a problem. You should always charge ws in the range from 20% to about 90 95.
Doesn't the number of charge cycles relate to the percentages? So that when you charge 50% only half of it is "used up"?
No.
Okay thanks!
The service life in cycles is heavily dependent on the depth of discharge (DOD). If you always recharge after removing 20% of the charge, the number of cycles is about 10 times as large. The battery lasts about twice as long.

But. The cycle life is always dependent on the depth of discharge.
This only applies to NiCd and NiMh batteries. Not for Li-Ion batteries. For lead-acid batteries it is imminent death.
If you have the option to limit the charge to 90% or 95%, do that.
Li-Ion batteries have the longest lifespan if they are neither charged too high nor discharged too deeply.
Of course, there's also the question of whether the charging electronics of the device see 100% at the maximum voltage of 4.2V per cell or voluntarily go a little lower.
The duration of the high tension is also significant. If the battery is immediately discharged again through use of the device, it is less of a problem than if it is completely switched off.
It is completely different with lead-acid batteries like car batteries, they prefer to be always full.
In order to ensure an optimal or longest possible battery life, you should start charging the cell phone / smartphone slowly when it only has around 15-30% left and then don't charge it up to 100% but rather up to 80-85%.
In addition, you should not continue to charge it when it has already reached 100%, i.e. Not leave it plugged in for several hours, e.g. Overnight, and not use it during the charging process.
In addition, you should always use original accessories from the manufacturer - i.e. Charging accessories and not rely on cheap third-party providers.
Furthermore, you should not use any quick-charging features, as these also significantly reduce the service life of the battery in the long term or reduce it more quickly in the form of faster wear.

The battery lasts the longest with a charge of 10 - 90%, but only about 500 charges.
