If you replace your Galaxy S7 charger or cable, be careful. There are many cheap third-party chargers that went bang in the middle of the night or turned smartphones into toast. As with any electrical equipment, make sure that anything you buy complies with all the relevant safety standards. Now, let's get on with the tips!

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.

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 seemless connections.

Consider charging the S7 wirelessly

Check the S7 charging port

Inspect the Galaxy S7 charging port. Is the charging port choked up with dust & debris? Yes? Often, a simple glance reveals nothing. With a can of compressed air, blow out the offending irritants and get your USB connection back to normal. If you don't have access to canned air, then blow (not spit) into the charging port.

Galaxy S7 DIY USB port fix

Do you know what one of the quickest, easiest, and often most successful solutions? A little DIY repair on your Galaxy S7 hardware. The metallic surfaces inside the USB port and the microUSB charger does not make proper contact. Through a manufacturer defect or because of the continual plugging and unplugging of the charging cable caused a severed connection.

  1. You need to shut down your device,
  2. Remove the battery and use something small. Try a toothpick. Lever up the little tab inside the USB port on your Galaxy S7.
  3. Do so very carefully and gently, then reinsert your battery (if you had to remove) and plug it in again. Nine times out of 10, cleaning the USB port resolves Galaxy S7 charging issues.

Update or rollback the OS on your S7

Software updates and new Android versions can play havoc with your battery life. This effect occurs when upgrading an old device to current software. Newer smartphones oft take advantage of the latest OS. Highly optimized, bigger cells and pre-optimized hardware. However, a two-year-old smartphone struggles when it makes the jump from behind the pack.

If this happens to you, consider rolling the device back to an earlier Android version. Turning back your device, however, carries security risks. (The latest software versions always keep your device protected. The risk of operating your smartphone on an older version is often negligible, but it’s worth noting.)

Similarly, the Galaxy S7 battery life significantly improves after some updates. Does your Android software version require an upgrade? Head to the 'about device' page in your settings and check for an update or do so via Samsung Kies.
