How to Keep Your Phone's Battery in Good Shape
Wed Jul 02 2025
Ever wondered why your phone's battery doesn't last as long as it used to? It's all about battery health. Your phone's battery health tools can help you understand and manage this. These tools show how much charge your battery can hold compared to when it was new. For example, if your phone's battery capacity was 5, 000mAh and now it can only hold 4, 000mAh, it's at 80% health.
Battery health is not the same as battery life. Battery life is about how long your phone lasts on a single charge. On the other hand, battery health is about how well your battery can hold a charge over time. Most phone batteries last around two to three years, but this can vary based on how you use and care for your phone.
When should you think about replacing your battery? If your battery health drops to 80% or lower, it might be time for a new one. A battery at 70% health can still work, but it might not handle high-power tasks well. It could even cause your phone to shut down unexpectedly or even damage your phone's hardware.
Your phone might have a charge cycle counter. A charge cycle happens when your battery goes from 100% to 0% and back to 100%. This doesn't have to happen all at once. For instance, if you drain your battery to 50%, charge it back to 100%, drain it to 50% again, and then charge it fully, that counts as one cycle. Most phones can handle between 500 to 1, 000 charge cycles.
Sadly, your phone's built-in tools can't improve battery health. They can only slow down the aging process. Features like adaptive charging can help. Adaptive charging pauses charging at 80% and then tops it off before you usually wake up. This is useful if you charge your phone overnight.
Some phones let you limit charging to 80%. This can help preserve battery health, but it's not always practical. You might want to use this feature if your phone is always plugged in, like when you're using it for navigation or gaming.
Not all phones come with battery health tools. If yours doesn't, you can use third-party apps like AccuBattery. This app gives you estimates of your battery health and other useful data. It can even alert you when your battery reaches a certain level.
Taking care of your phone's battery is important. As technology improves, batteries should last longer and be easier to replace. Until then, understanding and using your phone's battery health tools can help extend your phone's life.
