# How to Check Battery Health on Samsung Devices
Keeping your Samsung smartphone’s battery in top shape is essential for uninterrupted daily use. Battery health degrades over time due to chemical wear, usage patterns, and device age. Samsung devices offer built-in tools and third-party apps to monitor and maintain battery performance effectively. This guide covers the most reliable methods to check battery health and extend battery life.
## Understanding Battery Health in Samsung Phones
Battery health refers to the maximum capacity your battery can hold compared to its original state when new. Over months or years of charging cycles, lithium-ion batteries naturally lose efficiency—typically losing 20–30% capacity after 2–3 years of regular use. Modern Samsung devices track this degradation and display key metrics, but understanding them helps users take action. High battery health means longer usage between charges and reduced risk of sudden shutdowns. Samsung’s One UI integrates battery diagnostics to show real-time health percentages and charging behavior, empowering users to make informed decisions.
## Step-by-Step: Check Battery Health via Built-in Tools
Samsung devices provide a straightforward way to view battery health through built-in settings. Follow these simple steps:
- Open Settings from the home screen.
- Tap Battery under the Battery section.
- Scroll down to Battery health—here, you’ll see a percentage indicating current capacity. A reading near 100% means healthy; anything below 80% may signal degradation.
