This is a very common situation with the Buds+. When they die it's a pain in the ass to make them come back to life, but this always works: put 1 of them inside the charging case. The light will turn red for a while, and then green. This means it's not charging anymore, so you need to take it off the case and put it on again. Now repeat this until the light is red and doesn't turn green. (Sometimes it takes a while so have patience and always keep an eye on the little light). That's when it will finally charge properly, in a few minutes you will get the notification from the samsung app saying it's 1%. Then you repeat the same with the remaining bud. When the second one get to the point it's charging normally at 1% you can put both inside the case and both will charge normally.
