The polymer 18650 lithium battery 2600mah of a mobile phone itself has a certain charging cycle life frequency.

　　Mobile phones generally use polymer lithium batteries, and even high-quality rechargeable batteries only have a battery charge cycle life of 500-800 times. As the battery charging frequency increases, the battery's charge capacity will gradually decrease, so it will take a while for the mobile phone to avoid the current performance decline.

　　How to calculate the service life of polymer 18650 lithium battery 2600mah charging cycle system? Polymer lithium-ion batteries have the advantages of light weight, large size, and no memory. They are widely used in various mobile terminals, including people's mobile phones. Good quality polymer lithium batteries can be charged more than 500 times. Even after more than 500 times of battery charging cycles, polymer lithium-ion batteries will continue to have 80% of the original battery capacity and can be used again, but will also feel a significant reduction in retention capacity.

　　This battery charge cycle is not immediately measured by the battery charge frequency. Take 500 battery charging cycles as an example. If you charge at 50%, you can charge 1000 times. If you charge at 70%, you can charge 1500 times. So you don't have to worry about battery charging.

　　When is the best time to charge your phone?

　　Because polymer lithium batteries are most afraid of high temperatures, ultra-low temperatures and excessive charging and discharging. So do not charge the battery in ultra-low and high temperature natural environments. Some of you may have tried it. In the cold winter, you can't charge your mobile phone. You must warm your pockets to recharge. Excessive charging and discharging will also cause inevitable damage to lithium batteries. It is not recommended to use luminous batteries for charging. It is best to start charging at more than 20%.

　　What should you do if your phone's battery life deteriorates?

　　The decrease in the power performance of the mobile phone indicates that your mobile phone has been used for a period of time. Repair based on the mobile phone software is meaningless and has no great practical effect. It is best to replace it with an actual battery at a technical mobile phone repair shop.
