I've been having this issue that when my battery would be around 30%, suddenly the screen goes black and my tab turns off. I cannot turn it back on in any way, only by plugging it in a power source and then holding power and volume down..
So I replaced the battery...Now, with the new battery, it happens around 60%.
What's going on :(

I didn't have a sd card inserted but did have a non activated (no assigned phone number) Sim card inserted, I removed the Sim and problem solved. Not sure what will happen if I decide to activate the Sim card later

Lithium-ion batteries can be touchy things.
I have been told, that individual cells of a battery can fail. The electronics in the battery pack are constantly working to spread the load over the different cells.
If you measure the voltage of a single cell, (as the packs electronics are doing continuously) a certain voltage indicates the cell is fully charged. when you start to draw power to voltage will go down a small amount, and then plateau. If a cell has failed, when the amperage on the failed cell rises to a nominal operating level, the voltage will drop to near zero. The electronics in the pack will realize that the pack cannot maintain nominal voltage, and will cut all power off from the load (computer.)
This has happened to me personally, I had a MacBook Pro that would shut down cold at around 60% reported battery life. It was out of warranty and I had to buy a new battery pack.
My mom has experienced the sudden power failure on her iPhone 6s, which I suspect is the exact same thing. The reported percentage of battery remaining was not nearly as uniform, but I suspect that is because the degree of variation in current draw is much greater (as a percentage of maximum draw) and frequently it would happen at anywhere from 60% to 20%, but would frequently be triggered by doing certain tasks, like taking a picture.
There is always potential that you will receive a replacement part that was marginal, and will fail soon after being installed. That is the first line I would pursue. It is unlikely, but not impossible that the fault lies with the tablet itself, since changing the battery seems to have changed the symptoms.

I have the same problem and it's not the battery...I already tried replacing it. On another forum, I read a member sent theirs to Samsung and it turned out the issue was with the motherboard. It seems to be a common issue.

I’d first reset the darn thing to original factory settings, to rule out software issues…Unless you paid big money for the machine…any hardware issues at this point tend to fall in the screw it, let me go buy (from another brand) another one.

You most likely have bought a new tablet by now or have found a solution. Either or, I would like to add a solution I found on youtube that may work for those that have the same problem and don't feel like buying a new tablet. You can buy a portable charger and keep it plugged in to the tablet, so the tablet doesn't just turn off. Checkout the video.
