Galaxy Note 8 battery

Is your battery running out way too fast? Are you forced to recharge your Note 8 more than once a day? This guide will show you how to remove the tired old battery in your Note 8 and replace it with a new one.

Before disassembling your phone, discharge the battery below 25%. A charged lithium-ion battery can catch fire and/or explode if accidentally punctured.

If your battery is swollen, take appropriate precautions. Do not heat your phone. If needed, you can use a dropper or syringe to inject isopropyl alcohol (90+%) around the edges of the back cover to weaken the adhesive. Swollen batteries can be very dangerous, so wear eye protection and exercise due caution, or take it to a professional if you're not sure how to proceed.
