Many smartphone users have to charge their batteries several times a day, but experts have written that if you want to extend the life of the battery, you should try to maintain the battery power of more than 20% without full.
The average person who gets a new phone for the first time thinks it has to be fully charged for 12 hours or more before they can start using it. In fact, this is how nickel-metal hydride batteries are used. Most current cell phones use lithium batteries, which are completely unnecessary.
Some people are used to charging their phones before going to bed in order to get 100% power the next morning, but doing so is risky because there are still a very small number of chargers that don't have the ability to automatically stop charging when the battery is full. It is recommended to stop charging as soon as the battery is full to prevent accidents. After the battery is fully charged, the battery is still placed on the charger, which will also cause a slight decrease in the maximum charging amount of the battery. Long-term accumulation will have a relatively obvious impact.
And some people think that should wait for the battery recharged again after use, in fact, lithium battery charge not afraid, more afraid of no electricity, because one of the lithium battery charging manager, it ensure the battery can be normal charge, if lithium battery completely discharge, and hold a long time to charge manager power outages, lead to the battery cannot charge. For long-term use of batteries, such as camera batteries, it is recommended that you better ensure that more than 40% of the battery, the battery will lose about 5% to 10% of the battery every month, in other words, the battery will be exhausted in as little as 4 months and as little as 8 months. We need to recharge the battery before the battery is exhausted to ensure its stable state.
The life of the battery also has a great relationship with the working temperature. At 0℃, the maximum charging amount of the battery decreases by 6% every year, and the loss increases with the increase of working temperature. When used at 25℃, the battery loses 20% every year, and when used at 40℃, the battery loses 35%.
