Potential fixes for Galaxy S7 slow charging issue:

Hardware troubleshooting

The first hurdle to slow charging that many people overlook is checking the power adapter of the phone. Samsung galaxy S7 comes with ‘Quick Charge’ which allows you to charge the phone considerably faster than other devices. Once you start charging the phone you will get a notification which says ‘Fast Charging is enabled’. If it does not show this, then there is a problem with the power adapter and you need to change it.

There may be a problem with the USB cable as well which is not able to carry the desired amount of electricity from the power supply. In that case, try charging your phone with a different USB cable and if you see a progress then it is recommended to buy a new Samsung charging cable. If the issue still persists, read on.

If the power adapter and the USB cable seems to be working fine you need to check the charging port to see if there is a dust accumulation on it. This situation may arise after using the phone for quite some time and is a hindrance to charging. In this case, take a wooden toothpick and clean the port carefully. Getting rid of the dust may help solve the problem.

Software Troubleshooting

If there aren’t any problems with the charging port and the charger components, we need to move ahead and try to resolve the issue from within the phone’s environment. Here are some steps which need to be done:

Clearing unnecessary applications which are running in the background

A very common reason why your Samsung Galaxy S7 charges slowly is the presence of a number of background applications which are barely necessary after use which will continue to run in the background. They go on to consume quite a bit of memory, which contributes to sluggish performance and higher power consumption. Clearing all these applications will help in reducing the power consumed and also help the phone charge quickly.

Steps to clear these apps:

  • Press and hold on the Home icon and release it when you see a list of recently used applications.

  • Go to the Task manager section and select ‘End all applications’
  • On the task manager, you can also see the ‘RAM’ option. Select that and clear the RAM memory.

Uninstall any 3rd Party Applications

If clearing background apps did not work, there may be a software bug on your device. The best way is to uninstall any 3rd party applications that did not come along with the phone when you bought it first.

For uninstalling 3rd party applications, the phone needs to go to ‘Safe mode’ first. To enable this mode, restart the phone and when you can see the Samsung logo, press and hold the Volume down key till you see the ‘Safe mode’ message appear on the screen. Now in Safe mode, you can uninstall these apps by navigating to Menu> Settings> More> Application. Go to the ‘Downloaded’ category and select the 3rd part party applications and then tap on ‘Uninstall’, and when prompted tap on ‘Ok’. To come out of ‘Safe Mode’ press and hold the power key and when prompted tap ‘Restart’ and tap on ‘OK’.

Performing a System Dump

System Dump provides you with an image of ROM installed on your device and allows you to perform a complete restore, which takes the phone back to its original factory settings when it was bought if something goes wrong. To perform a system dump, do the following:

  • Type in *#9900# in the phone dialer
  • A page will pop up, go to the bottom of it and select ‘Low battery Dump’
  • Finally, select ‘Turn On’

These are some of the ways which can help resolve the slow charging problem on your Samsung Galaxy S7. If none of these work, take it to the nearest Samsung Care store and get it checked by a technician.
