Introduction The newly purchased IPAD4 was used to automatically turn off and charge yesterday, and I heard that this is very harmful to the battery. . It doesn't matter this time. Using auto-off actually damages the battery.

Using auto-off is actually very harmful to the battery. Turns out it's completely drained before charging because it's a nickel-zinc battery that has a memory effect if you charge it after 20 uses. % power, it will slowly default to 80% is the maximum power, which will cause the battery capacity to drop quickly. But today's cell phones use new lithium batteries. Lithium batteries contain chemical energy and have a high density of ions per unit area. If batteries are depleted before being charged, the ions will become inactive and seriously damage the battery. The correct charging method is to charge as you use it, provided that it can be charged (but do not charge continuously for more than six hours), and the minimum charge cannot be lower at 20%. Then load and unloadez completely at least once a month (in order to fully activate the ions that are generally not used), that is, the battery is less than 20% (preferably 18~19%), then charge until full, then charge. for half an hour it's better to download A Battery Doctor or something.

Basic knowledge of batteries and charging

1. The iPad battery is a lithium battery, unlike the previous nickel-zinc lithium battery, which does not have a memory effect. the worst is that it is completely discharged. .. This will cause premature aging of the battery;

2. There is an automatic protection circuit inside the lithium battery. Once it is fully charged, the circuit will be fully charged. automatically cut off, but for safety reasons, remember to remove it after plugging in the charger;

3. The iPadhas automatic battery adjustment. When the battery is too low, it will automatically turn off. . Note that the iPad battery is still charged at this time. If not used, it will turn off in about 3-5 days. Therefore, when the iPad says the battery is too low or turns off automatically. , you have to remember to charge; avoid complete discharge and damage to the battery;

4. The iPad battery can be fully charged or partially charged, this does not affect battery life (it's completely different). from the previous nickel-zinc batteries, don't cling to the old concept of charging ~~), you can charge the lithium-ion battery at any time as long as it is convenient for you;

5. The battery is a consumable and will gradually reduce its maximum power if not used; therefore, enjoy your iPad as much as possible; a userare ation will not extend battery life too much;
