Does the new ipad charge after the first automatic shutdown? So how long does it take to charge for the first time?

All the precautions about the first charge and discharge are aimed at the previous Ni-MH battery or Ni-Cd battery. Lithium batteries don't need deliberate deep charging and discharging, all lithium batteries need long-term charging, and the statement that deep discharging is charging is wrong.

Lithium batteries can be charged as needed.

In addition, whether it is the first time to charge the ipad or not, it will automatically switch to the power mode after charging protection, so even if you charge it for three days and three nights, it is still an effect and meaningless.

Just use it and charge it. There is no need to charge it several times before using it. It's all in the past, not for lithium batteries.

The only thing to pay attention to is not to use it for a long time. If you don't use it for a long time, you should take it out and charge it at least once regularly. Before storage, you should keep a certain amount of electricity in it (not necessarily full). In short, lithium batteries are not afraid of use and discharge.
