The Buying Guide

If you’re looking for the details on Galaxy S8 battery replacement cost, we hope this buying guide will be of help. First off, we can estimate that as much as you’re willing to follow a few simple steps, the battery replacement process is pretty much a DIY one.

So, you can spend in the range of $10 - $20 for a replacement battery. Usually, these replacements come with an installation kit.

The kit can also be found alongside the user manual. If the user manual isn’t available, you can always find some helpful installation videos online.

Some of the factors to consider when shopping for a replacement battery include.

(1) Quality – Always go for a well-made battery. Ideally, you should only go for one that’s well-made and duly certified by the like of FCC, CE, and ROHS.

(2) Warranty – It’s important to find a unit with the right warranty terms. We’d recommend settling for nothing short of a 1-year warranty at the very least.

(3) Extras – Go for a battery that provides you with an installation kit and a user manual. Note: if you’re already familiar with the installation process and have the tools already, you can save a few bucks. Replacement tools without the extras are normally cheaper than ones with them.
