S8+ Only Vibrates When Power Button Is Pressed

Problem: Hello, i’ve tried doing the troubleshooting procedures on my s8+ .I’m not sure what else to do. Sometimes if i hold the power button for 5+ seconds the phone will vibrate and the charging symbol and ring will appear for about 1 second then it’s gone again. i’m going to leave it overnight to charge and in the morning hopefully it turns on if it doesn’t then im at a loss. please help me

Solution: If your phone just vibrates when you try to turn it on with nothing else happening then it’s very likely that the battery does not have sufficient charge. Listed below are the troubleshooting steps that you need to do to fix this charge the phone.

  • Clean the charging port of the phone with a can of compressed air making sure that any dirt or debris stuck in it is removed.
  • Charge the phone for at least 20 minutes using a wall charger then turn on the device.
  • If the phone does not turn on then try using a different charging cord and wall charger to charge the phone. You should also check if the phone charges from a computer USB port.
  • Try starting the phone in recovery mode then do a factory reset in here. Take note that this will erase your phone data.

If the above steps fails to fix the problem then this is most likely caused by a faulty hardware component in which case you will need to bring the phone to a service center and have it checked.

S8+ Battery Drains Quickly

Problem: Hello, I have a question regarding my S8+. Since I updated the latest Android  (around December), initially it was pretty good. However, I think from February I started noticing medium battery drainage and then in March it was worse. I had to always connect it to the charger because after 10 or 20 mins it would go from 100% to 1% or 100% to 50% (shut down). It wouldn’t restart until I connected to the charger. I usually had battery issues earlier while using snapchat which I avoided since the issue. Later, this month I discovered that my google account wasn’t backing up. I reported it to google with no success. Hence, I decided to factory reset while risking of not having the latest backup. Later, it fixed the backup issue but it wasn’t efficient and then after a few days I started having google sign in issue. It would not sign in on this device yet my account worked well in other devices. So I had to factory reset it again. Meanwhile during these issues, the battery drainage persisted and I even tried to do a hard reset. But every time I reached the stage “recover to bootloader mode” , the battery drained to 1%. So I was not able to hard reset it. Even safe mode method didn’t help at all. I am not sure what should I do next and it is pretty frustrating because I can’t use it without constant charging. I would be glad if you could advise me on this matter.

Solution: If after performing a factory reset the battery still drains very quickly then this might already be caused by a faulty battery. One last troubleshooting step that you can do in this case is to remove the microSD card of the phone if you have one installed as this might be causing the problem. In case the issue still persists even when the phone does not have a microSD card then you will need to have this checked at a service center.

S8+ Not Turning On Unless Plugged To Charger

Problem: I have a Samsung Galaxy S8 plus with a battery issue. It will shut down at anywhere from 70%-30% after fully charging and will not come back on until plugged in. When powered back on the battery percentage isn’t the same as when it died. I’ve performed a factory reset the phone and still haven’t fixed the problem

Solution: Since you have already performed a factory reset which does not fix the problem then this is most likely a hardware related issue possibly caused by a faulty power IC or battery. The best thing to do right now is to bring the phone to a service center and have it checked.

S8+ Will Only Charge On Computer USB Port

Problem: I have a Samsung S8+ that all of a sudden stopped charging with the factory supplied wall charger. The phone runs fast & flawlessly otherwise. This charger works on another device. A second wall charger also will not work on my phone but will on others. A wall adapter with USB cable, also does not work. My phone WILL charge via USB cable connected directly to my PC and laptop, both at home and work. My phone is running stock software no ROMs, not in developer mode, etc.

Solution: For this particular issue you should try cleaning the charging port of the phone using a can of compressed air then try charing it again using a wall charger. If the issue persists then it’s very likely that one of the pins of the charging port assembly is damaged. You will need to have this checked at a service center if this is the case.
