My Samsung T290, bought second hand in the UK during last summer, has had this problem all winter. For a long time, I just thought later technology was protecting lithium batteries better in later models. Later, the thought evolved to thinking it was over-protective, so began to wonder at what temperature should this stop happening.
I only started looking for forum comments about it today when I found the same thing happening on a morning where the air temperature on my way to a library to do the research was about 12^^o^^ C.
I note the previous comments. During the winter, the tablet has been charged via several cables, so it is not a cable issue. I am now really concerned about the situation because it now looks as though there might be a real fault with the sensor on or near the USB socket. If it is a corrosion problem, it is certainly not through any mishap I have had with rain or other water but during the winter, there was often condensation on the screen when the case was opened indoors, so it could have got into the USB socket as well.
Someone had a model with a removable battery but the T290 and T295, for example, do not have removable batteries, so I am currently stuck with this problem. The only consolation is, I have discovered it is a real issue before this winter has quite come to an end, so the morning air is still quite cool – apparently still cool enough to show up the problem.
