Yes, charging a smartphone up to 80% can increase battery life. In fact, following the 20-80 rule is one of the best battery practices you can adopt to prolong the lifespan of your smartphone battery. This principle is also applicable to other types of batteries, such as those used in cars, as discussed in our Ultimate Car Battery Guide.
The 20-80 rule, also known as the 40-80 rule, suggests that you should keep your smartphone battery between 20% and 80% charged. This means that you should avoid letting your battery drain completely and avoid charging it to 100% unless necessary.
Why is this important? Lithium-ion batteries, which are commonly used in smartphones, have a limited number of charge cycles before they start to degrade. Each time you charge your battery to 100%, you use up one of these cycles. By keeping your battery between 20% and 80%, you reduce the number of cycles you use and prolong the lifespan of your battery.
But what about when you need to use your phone for an extended period of time? It's okay to charge your battery to 100% occasionally, but you should avoid doing it regularly. Additionally, it's important to avoid bad charging habits, such as charging your phone overnight or using a non-certified charger, as these can also damage your battery. These principles are not only applicable to phone batteries but also to car batteries. You can learn more about this in our article on Top Car Battery Maintenance Tips.
In addition to following the 20-80 rule, there are other steps you can take to optimize your phone's battery life. For example, you can adjust your phone's settings to reduce battery usage, such as turning off location services or reducing screen brightness. You can also avoid using battery-intensive apps or games for extended periods of time. Similar steps can be taken to optimize the life of other types of batteries, such as those used in electric scooters, as discussed in our article on Different Electric Scooter Battery Types.
Overall, following best charging practices and the 20-80 rule can help prolong the lifespan of your smartphone battery and ensure that it lasts as long as possible. Similar practices can be applied to other types of batteries as well.
