In general, we can safely say that we are quite pleased with how the Samsung Galaxy Tab S7 is shaping up. The leaked specs provided by Samsung pretty much confirmed everything we suspected about the upcoming tablet, but now another leaked spec could seriously jeopardize its hopes of being the ultimate iPad Pro rival.

The certification from China's 3C authorities, discovered by SamMobile, highlights a weakness: 15W charging. Technically, 15W falls into the category of "fast charging," but this kind of speed was achieved half a century ago, and chargers are now capable of producing 60W or more of power.

The technology is not new for Samsung either. The Galaxy S20 supports fast charging at up to 25W, and the Galaxy S20 Ultra at up to 45W.

The S20 has a 4,000mAh battery, while the Galaxy Tab S7 is said to have a 7,760mAh battery; the Tab S7 Plus is said to have an even larger 10,090mAh battery, so charging the larger model Unless the technology is upgraded, waiting for the tablet to charge from empty to full may be painful.

The Tab S6 has the same limitation, with the general consensus being that it takes about two hours to charge from flat. Not too bad, considering the tablet's impressive stamina, but adding fast charging would have allowed the Tab S7 to outperform the iPad Pro.

It is unfortunate that Samsung seems to be maintaining slow charging speeds on its tablets while being quite open to faster solutions on its phones. However, this appears to be the only notable drawback of the Tab S7: the rest of the specs (and the design of the pictures - courtesy of Pigtoucoques) look pretty darn good.

We expect a speedy device with the upcoming Qualcomm Snapdragon 865 Plus CPU, backed by 8GB RAM. The tablet was recently leaked to Geekbench, where it scored 971 points on single-core and 2,984 on multi-core.

The tablet is also set to inherit the S20's 120Hz screen, an upgrade that should make the included S Pen even more fun to use, assuming it gets the same 9ms boost rumored for the Note 20.

The only difference between the Tab S7 and S7 Plus versions will reportedly be the form factor: screen size and battery capacity.

We expect the Galaxy Tab S7 to be revealed very soon - the official Samsung Unpacked event is rumored to be just a month away, after all. That said, don't be surprised if the Tab S7 is launched early to give the company's other big announcements a breather, as the Tab S6 did last year.
