The Samsung Galaxy S9 and Galaxy S9+ are expected to be announced on Feb. 25 and it will be showcased in Barcelona during MWC 2018. Although the official launch is still a few weeks away, the battery capacities of both handsets appears to have already been leaked online.

The batteries for the Galaxy S9 and S9+ were shared online by Slashleaks earlier today. Apparently, the Galaxy S9 will have a 3,000mAh battery, while the S9+ will have a larger 3,500mAh battery. Unsurprisingly, the battery capacities for both devices are the same as their respective predecessors.

The images of the batteries were listed by Union Repair, a cellphone repair wholesaler online store based out of China. The same store also has a listing for the S9’s charging port flex cable, with the full model number of the device listed on the flex cable itself. SamMobile points out that it seems plausible that Samsung is already supplying parts retailers to stock up on Galaxy S9 and Galaxy S9+ parts.

Both devices will make their first official appearance on Feb. 25 and sales are expected to commence sometime in mid-March, possibly March 16. Samsung may already be preparing retailers, carriers and smartphone stores across the world now since there really isn’t enough time to do that when the devices are officially announced.

The battery capacities of the Galaxy S9 and Galaxy S9+ may disappoint some fans who were expecting larger batteries. However, the batteries in the Galaxy S8 and S8+ have proven to be very good. It’s very likely that Samsung will continue delivering impressive battery life through power-saving modes and other optimizations.

Another thing to consider here is that these batteries are for the variants using the Qualcomm Snapdragon 845 processor, as pointed out by Android Headlines. The Snapdragon 845 is said to be 30 percent more power efficient than the Snapdragon 835, while also delivering 25 percent uplift in performance.

The Samsung Galaxy S9 is expected to arrive with a design that’s pretty similar to the Galaxy S8, but with some small changes. Renders for the device were leaked earlier this week showing the fingerprint scanner is now centered on the back rather than sitting right next to the camera lens. It also appears that Samsung may made the bottom bezel slightly thinner on the S9.

The Galaxy S9 is also rumored to arrive with a feature that’s called Intelligent Scan, which combines facial recognition and iris scanning technologies. The new feature seems to be Samsung’s own version of Apple’s Face ID on the iPhone X.
