Re: Incomplete connection charging.

I had the same charging problem using the supplied charger and cable. The charging port on the phone proved to be the problem. I exchanged the S8 for another and the cable fit much tighter. Looks like a batch was defective.

Sounds like an evaluation and repair is in order. Definitely reach out to Samsung directly via Phone (1-800-SAMSUNG/1-800-726-7864), Twitter, or even Facebook.

Likewise, you can always reach out to your carriers for an exchange like @userKMCLZoHoK4 mentioned.  Smiley Happy

My daughter's S8 began having this exact problem.  She leaves it on the Samsung original equipment charger all night.  It only reaches 5% charge.   I was going to buy a Samsung Galaxy S8+ next week, but now I am reconsidering.  How is Samsung going to fix the S8 and S8+ phones?  Last week, I had a Galaxy S7 Edge blow up.  It caught on fire and smoked for many minutes.  I've always thought that Samsung phones were the best, but these issues are becoming a big problem.

I purchased a bag that comes with a joey charger to use with mobile phones and got the incomplete connection error message. I called your number and was told that you can only charge your phone with a power source from Samsung. That's pretty manipulative and lame. Why should this be any different from plugging into the wall or a computer to charge???

 

I called again and the person i spoke with this time said that you can charge with other sources as long as you use the Samsung cord and to contact the company that made the power bank...

I am having the same problem; I had to return my phone after 2 months they sent me a new one which worked for a while but now I am getting the same incomplete connection message. This is super frustrating Samsung has gone wayyyyy downhill with the S8!

After two weeks of no resolution, I called Samsung and they wanted me to rest my phone. I didn't want to go through that process, so I took my device to a Verizon store. We plugged the device into multiple chargers with no success. Verizon recommended I replace the phone.

 

Thinking the port is dirty, I went to clean it one more time. I used compressed air and this time added suction from a vacuum. I plugged the device back into a USB-C charger and it started working as normal. I was surprised.

 

My assumption is there were dust or sand particles that were causing the problem.

This just started for me in the last 2 days, all of my chargers do this now. I've had limited success rotating the USB-C plug. Sometimes that will clear it up.

My husband is having the same issue with his S8.

 

We purchased the phone at Best Buy 5/12/2017. He just started having the charging problem in late July. I have emailed Samsung and I am waiting for a response. Like others, here are some of the issues I am seeing and what we've done to try and resolve it.

 

Issues:

-Fast-charging not working

-Phone charging extremely slow and displays that the remaining charging time is up to 20 HOURS

-Leave phone plugged in overnight and only get up to ~35% charged

-Receive notification stating to check the connection of the charger.

Troubleshooting:
-Only using the charger that came with the phone
-Blown out ports with air
-Swabbed port with rubbing alcohol and dried
-Disabled and Re-enabled Fast Cable Charging
-Powered on/off device
-Completed a factory reset
-Sometimes when I flip the plug over it works like normal, but not always

I had a similar problem when i used a micro-usb with the adapter. When I left my phone case on and plugged it in my phoned it would not charge correctly. So I would try taking the case off than plugging it in. When I had the case on it seemed to be seatted correctly, but no. I hope helps. This was also the case with my OTG adapter. So yeah try without the case on.
