LR03 alkaline battery.'Chilled' smartphone batteries: Extended life! ?

　　In fact, lithium-ion batteries will have adverse effects when exposed to "heat" and "cold". Indoor temperature is the optimal temperature for smartphone batteries, and it is best to place the device in a well-ventilated area.

　　Nowadays, it is common for smartphone batteries to be charged every day. Various power consumption causes headaches. Correct charging habits and good battery maintenance methods have become a top priority for many users. Are all the weird methods on the Internet right or wrong?

　　Will charging overnight damage the battery?

　　"I put my phone on the bedside table to charge it every night, and I charge it all night. I recently heard from a friend that charging it all night would damage the battery, and I was very worried. Netizen Ms. Liu said that her phone has been used for a year. A well-known brand of smartphone. In fact, there are many people like Ms. Liu who charge their phones overnight.

　　Comment: This statement is wrong. When the battery of most smartphones is saturated, it will automatically stop charging without damaging the battery. But it is best not to charge it all night. Users can try to charge it to 40%~80% in most cases, which can ensure that the battery has as long a life as possible.

　　“Ice-cold batteries last longer?

　　Recently, Ms. Zheng discovered a very popular post saying that batteries that have reached the end of their service life can be restored after being placed in the refrigerator. "Following the method detailed in the post, I wrapped a mobile phone battery that had a slight bulge in the middle with newspapers and then wrapped it in a plastic bag. After freezing it for three days, I took it out and left it at room temperature for two days. Then I charged the battery until it was fully charged. Then she installed it into a mobile phone and tested it. Ms. Zheng told reporters that it did not achieve the effect mentioned on the Internet.

　　Comment: This statement is also wrong. In fact, lithium-ion batteries will have adverse effects when exposed to "heat" and "cold". Indoor temperature is the optimal temperature for smartphone batteries, and it is best to place the device in a well-ventilated area. If your phone is sealed, the heat will affect the phone and battery. But compared to heat, cold is more harmful to the battery.

　　Turn off WiFi to extend battery life?

　　"I used to turn off various functions such as WiFi, Bluetooth, and GPS when I was lying in bed at night to save power. But then I accidentally forgot to turn it off and found that the power was still used up very quickly, which was no different from when I turned off the function before. Netizen Yu Mingbiao has a negative attitude towards the claims made online about extending battery life.

　　Comment: This statement is also wrong. These services only really consume power when the user is using them. If we only turn on WiFi, Bluetooth, GPS and other functions but do not use them, they will not consume too much power. The best way to extend battery life is to dim Screen brightness.
