Can reducing cell phone charging by 80% increase battery lifespan?

Cell phones have become essential to daily activities and users are increasingly concerned about battery life. Manufacturers are introducing new features like adaptive charging to extend battery life. Android 15 now offers the option to limit battery charge to 80%, but its impact on extending service life is uncertain.

Why does a cell phone battery degrade over time?

Two primary elements that contribute to the deterioration of lithium-ion batteries in most mobile devices are heat and voltage. Heat can be produced by external factors, such as exposure to sunlight, as well as by using the device while it is charging. On the other hand, high voltage, especially when the battery reaches full charge, speeds up the deterioration of the battery. As the battery nears its maximum capacity, the internal voltage rises, leading to increased stress on the chemical components, causing material wear and reducing the overall battery capacity over time. Consequently, frequent charging of the mobile device up to full capacity can accelerate this degradation process.

Does it work to limit the cell phone’s charging to 80%?

Limiting the load to 80% helps maintain lower internal voltage levels in the battery, reducing stress on chemical components. This approach lessens heat generation during charging and delays battery wear, potentially extending battery life without greatly affecting daily device usage. The impact of this practice on longevity may vary among users based on charging habits and frequency.

In which cases should I restrict the shipment to 80%?

• Charging your smartphone multiple times a day can cause unnecessary wear, so limiting the charge to 80% can help reduce this.
• Using heavy applications or playing games frequently can cause the battery to degrade quicker if it is frequently charged to 100%.
• Older batteries deteriorate more quickly over time, and reducing the load can help to delay this deterioration.

How can you enhance the longevity of your mobile phone’s battery?

Other steps can also assist in maintaining the battery’s health aside from restricting the load.

• Extreme temperatures should be avoided as they can harm the battery. It is recommended to use original chargers to maintain the battery and device life.
• Maintain the software current: software updates often include enhancements in power management, which can enhance battery efficiency.
