I am having the same issue. It seems this is a problem experienced by too many people. The Note 10+ is a premium phone for Samsung. We should not have to resort to clamps or pressure for what is obviously a sub-par component or assembly process.
What is the permanent solution to this problem?
Use a wood clamp and clamp the front and back together and plug in. That's the only way I could get mine to work. I'm finally tired of it and bought a Google Pixel 4a. Much better phone.
The "Accept Solution" on this lengthy thread does not seem to hint at any sort of answer :(
My Note 10+ just started having this problem this weekend.
I downloaded an app to show me my battery temperature and sometimes it reads low between -4F and +4F but other times it reads normal (between 75F and 100F). Obviously, when its low, it wont charge. And of course, there is no way the battery is actually that cold.
I would love to have more info about what is going on. But to this conversation, I will add two points:
1) I've found that when the temp is low it is almost always when I have the case on my phone. Furthermore, taking the case off generally returns the temperature to normal within a few seconds.
2) I have always had problems getting wireless charging to work on my phone. I always assumed it was a setting configuration I was doing wrong, but I've learned that the battery temperature sensor is on the same film-like hardware piece that receives power wirelessly. Coincidence? Who knows.
Why can't Samsung share the solution?? Why private message people? Probably because it's a manufacturers defect that causes a loose or broken connection in the wireless charging coil that many posters have said continues to fail after Samsung "repairs" the problem! Samsung quality has clearly gone WAY down. Turning our $1,000 "flagship" phones into $1,000 paper weights! Great job Samsung, you've lost this long time once loyal customer of many Samsung products. In the business that I'm in, quality products and good customer service are what is most important. Too bad Samsung doesn't think so.
I am having the exact same problem. I have took it to UBreakIFix and they said it is the motherboard and has to be repaired by Samsung. I have called twice and cant get any response! After dealing with the old Samsung 7 battery issue and now with this I have a very sour taste in my mouth regarding Samsung All I want is for them to fix this phone....
