Solved Samsung Galaxy S9 Not Fully Charging

The #Samsung #Galaxy #S9 is the newest flagship Android smartphone of the South Korean giant that is a refinement over its predecessor. This new model sports a much powerful processor ( Snapdragon 845 or Exynos 9810 depending on market region) combined with 4GB of RAM allowing the phone to perform very well. It still uses the same 5.8 inch Super AMOLED display as the S8 with the screen occupying most of the front part of the phone. Although this is a solid performing device there are instances when certain issues can occur which we will be addressing today. In this latest installment of our troubleshooting series we will tackle the Galaxy S9 not fully charging issue and other related problems.

S9 Not Fully Charging

Problem: Hi, So I have a Galaxy S9 and i have had it for a month. I plugged my phone in and it displays the amount of time until fully charged and it said 2 hours and 10 min. I was at 80%. I left it alone for 2 hours and came back and it was at 83%. I tried my two charging “blocks”(the things that go into the wall) and then 6 micro usb chords in each some 3 ft and some 6ft and the charge time remained the same. I don’t know what to do but I need to have a fully charged phone and it taking over 2 hours to charge 20% is not going to work. As of right now it still is not fully charged and i plugged it in at 4:30, its 8:00 now. Please get back to me asap bc I dont really have time to go to the store if it is something I can fix.

Solution: What you will want to do first in this case is to check the charging port of the phone for any signs of dirt or debris as this could interfere with the charging process. If necessary you should clean the port with a  can of compressed air. Once the port is clean try charging it again (it’s better to try different charging cords and wall chargers when charging the phone). In case the problem persists then continue with the steps listed below.

  • Start the phone in Safe Mode then check if the issue occurs in this mode. If it doesn’t then an app you download might be causing the problem by constantly using battery hungry resources such as the processor. You should find out what app this is and uninstall it.
  • Backup your phone data then do a factory reset. Once the reset is complete check if the issue still occurs.

If the above steps fails to fix the problem then this could already be caused by a faulty hardware component, possibly the battery. You will need to bring the phone to a service center and have it checked if this is the case.

S9 Battery Draining Very Fast

Problem: Battery is draining very fast. After charging all night without being on within in 5 minutes of use down 6%! My phone used to last almost 24 hour with minimal use. I don’t play games on my phone and no social media. Now it won’t last till 2 PM. It is also slower.

Related Problem: My phone for a while would charge slow other times at a normal rate , but since last night I was having trouble trying to get it to charge so i left it charging all night. This morning i got my phone which loses battery super fast , by the time it was on 30% i tried charging it but it wouldn’t charge at all , it didn’t show the charging icon either , later on in the evening i charged it while it was off and it charged about 5% but definitely super slow, the screen goes of and on none stop , what should i do or what can help ?

Solution: The most common factor that can cause a battery to drain fast is an app installed in the phone or some corrupt data. This is what we will be checking first.

  • Make sure that your phone is running on the latest software update.
  • Try starting the phone in Safe Mode then check if the battery still drains fast in this mode. If it doesn’t then the problem could be caused by an app you downloaded. Find out what app this is and uninstall it.
  • Backup your phone data then do a factory reset. Once the reset is complete do not install any apps in your phone. If you have a microSD card installed in the phone then remove it. Try checking if the issue still occurs.

In case the issue persists and your phone is using an Exynos processor then I suggest that you wait for a future update to fix this problem as this is a known issue affecting the Exynos line of the S9.

S9 Not Turning On After Getting Wet

Problem: So just came back from vacation (beach) and after a snorkeling session, noticed moisture and my Samsung Galaxy S9 would not power up and the display was black. Tried the rice trick which did not work. Now the phone is blinking red when trying to charge the phone, question is, is there any hope of recovering any data from the phone at this time? So gutted!!! Any useful information is most appreciated.

Solution: If you have already placed the phone in a bag of rice for at least 48 hours and the issue persists then water might have already entered the phone causing some damage to its components. Although this phone has some water resistant features it is still possible for the device to get water damaged especially if the rubber seals are broken. Regarding the data stored in the phone you won’t be able to access this unless the phone switches on. Assuming the internal storage is not damaged then you can access this data if you have the phone repaired at a service center.
