Use the correct Galaxy S7 Charger

Make sure that you are using the Samsung charger and cable that came with the S7. Other chargers may have different voltage ratings, and they won’t always work with the S7. If your charger doesn’t deliver the right charge frequency, check that it’s the right charger. A charger from another device might not provide the right amount of power.

For example, a charger for a Bluetooth headset won’t put out as much power as one designed specifically for smartphones. In the case of the Galaxy S7, use a Galaxy S7 fast charger.

Charge the Galaxy S7 for a while before turning it on

As a rule of thumb, allow your Galaxy S7 to charge for about 30 minutes. Do this before you attempt to use the S7.

Read on for more tips to fix a Galaxy S7 that is not charging.

Try a new wall socket

Change the wall socket and use the cable and charger on a different device to make sure there are no faults with the charging apparatus. Try a different charger and cable with the same voltage rating. Note: Charging from a wall socket always charges faster than via PC or laptop. Most computers’ USB ports don’t deliver very much power.

A wall outlet produces twice the power than that of a USB port. In the case of fast chargers, it gives as much as five times the power — which means much, much more quickly recharging.

Charge the Galaxy S7 via USB/PC

Try plugging the S7 into a USB port on your PC or laptop. Although, it will load much more slowly using the USB port than from the charger connected to the wall. Phone Companion displays the amount of charge your Galaxy S7 receives. Also, Phone Companion details available space (both internally and externally).

Phone Companion also allows you to import photos, videos, etc. It is a friendly interface. So, check out Phone Companion if you’re on Windows 10. Moreover, download the correct Samsung Galaxy S7 USB drivers to ensure seamless connections.
