When it comes to the battery of our smartphones, there are two things we have to consider: battery life and battery health.
- Battery life basically refers to how much battery is left based on the current charge. This is usually displayed in your phone's status bar and should give users a rough idea of how much battery they have left before the phone dies.
- Battery health refers to the overall health/life of the battery. This is something that degrades over time the more you charge it. It is measured in cycles where each charge from 0-100% is counted as one cycle, and typically all lithium-ion batteries used in our mobile devices have a limited number of cycles.
Why is Battery Health Important?
The health of your battery also determines how much charge it can hold. For example, a phone with a 5,500mAh battery and 100% battery health means it will hold 5,500mAh as promised when fully charged.
So if you're wondering why your phone is no longer lasting as long as it should, maybe you should check its health and here's what to do.
Checking Your Android Phone's Battery Health
Using Dialing Code
- Launch your phone's search app
- Type *#*#4636#*#*
- You should now be brought to a menu
- Search for “ battery info “
If you don't see “ Battery info ” or similar, it means your device will not be able to access this feature.
You can use AccuBattery , one of the most popular tools, to check not only battery health but other battery related information .
- Download and install AccuBattery
- Launch the application
- Tap the Health tab at the bottom of the screen
- Under Battery Health, it shows the health of your phone's battery.
For AccuBattery to better understand and read your phone's battery, you can run it on a few charges so you can be sure you'll get the most out of it. Therefore, stepping through the next few days will likely give you a more accurate reading than when you first started.
