Four days after starting the Galaxy S6 hype train with a camera teaser, Samsung has dropped a couple more hints about its next Android flagship.

First up, Samsung Mobile’s official Twitter account has posted a brief Twitter video that hints at the Galaxy S6’s performance. The video includes the text “The faster I am, the more that gets done. And the more time I can give to others. I am #TheNextGalaxy” and ends with a lightning bolt that could be a hint at the S6’s processing power.

I am #TheNextGalaxy. See how I give more time to others at #Unpacked. https://t.co/zfYs03p90P

Meanwhile, Samsung has put up a blog post on its official Samsung Tomorrow blog that’s all about wireless charging. The company tells us all about its history with wireless charging in mobile devices like the Droid Charge, Galaxy S4, and Galaxy Note 3. Samsung declares that 2015 will be “a landmark year for smartphone wireless charging” at the end of its post, going on to say that it will work to democratize wireless charging with “compelling smartphones” and that with its upcoming Galaxy devices, “users will be able to enter a wireless world like never before.”

So judging by Samsung’s latest teasers, the Galaxy S6 is going to have improved performance and wireless charging, neither of which is a surprise. One thing relating to performance that is worth noting is that rumors have suggested that Samsung will use its own Exynos processor in the Galaxy S6 rather than Qualcomm’s Snapdragon 810, and so I’m sure a lot of folks will be interested in seeing exactly how the S6 handles.
