does the Tab S 10.5 have LEDs to show that it's charging?

Nope, no status LED :(
Only an audible alert and a visual cue on screen when charging.
 
Do you have volume turned up? Or maybe I imagined it? haha I usually keep mine on vibrate since I don't like hearing my e-mails coming in at night, so I just 'feel' when it's charging, maybe I thought it made a sound... I'll have to check since, ironically, left mine charging at home haha

When it reaches 100%, the screen turns on for about 15 seconds and then turns itself off again. Unless I happen to be right there during the 15 seconds, I won't know that it has finished charging. I also turned the volume all the way up, but it doesn't make any sounds when charging is complete.... I guess I need to look into installing some apps to do that. :)
 
All Samsung devices turn the screen on when they're done charging and when you unplug them (as long as the smart cover is not closed), but yeah, no sound to let you know it's done. The sound I THINK I heard was when you plug it in and it starts charging, but no sound when it's done.
 
It does make a little tweeking sound when the power adapter is plugged in. Mine was fully charged to 100% and plugged in. I just UNplugged and then REplugged and it made that sound.

I don't know what it may or may not do when it hits 100%.
 
Then I didn't imagine it. Nice. But yeah, it doesn't have an audible alert when it's fully charged. It just, well, stops charging haha. But it does turn the scree on and shows a notification on the notification bar.

Yeah, that notification bar is a bit crowded - just counted and on the left are 30 little icons. Right, shows Bluetooth, wifi, battery percent, battery graphic and the clock.
