The S20 series has been around long enough now that a good number of them are starting to show their age — not in the screen or the cameras, which still hold up beautifully, but in the one component that quietly wears down no matter how carefully you treat it: the battery.
How to tell if it's the battery
- A full charge doesn't get you nearly as far as it used to
- The phone switches off suddenly, often above 20%
- It runs noticeably warmer than it did when it was new
- Performance dips that ease up once it's plugged in
How we handle the S20 series specifically
Each model in the range — S20, S20+ and S20 Ultra — has its own battery size and fit, so we make sure the replacement matches your exact phone. We check the battery's actual health first, fit a quality replacement if that's the right call, then confirm charging and battery reporting are both behaving normally.
Worth doing before you upgrade
A tired battery is one of the most common reasons people consider replacing a phone that's otherwise in great shape. Often, a fresh battery buys you a good while longer with a device you already know and like.
