The alleged battery capacities of the Galaxy S9 and Galaxy S9 Plus leaked online on Thursday, having been shared as part of replacement battery listings published by Hong Kong-based smartphone repair service Union Repair. The cells powering Samsung’s upcoming pair of Android flagships will retain the same capacities supported by the ones found inside their direct predecessors, according to the source. The Galaxy S9 is hence said to feature a 3,000mAh battery, whereas the Galaxy S9 Plus should ship with a 3,500mAh unit, neither of which will be removable, though both should support Samsung’s Adaptive Fast Charging technology and also be complemented by a wireless charging coil. The two batteries prematurely listed by the repair service appear to be of the official variety, with their photographs shown in the gallery below clearly showing product labels claiming they were assembled by Samsung SDI’s Vietnamese division, whereas their components were supposedly manufactured by the firm’s Chinese unit.

The nominal voltage of both batteries is listed at 3.85V and their charge voltage is set at 4.4V, with these specifications being identical to those attached to the batteries powering the Galaxy S8 lineup. While no other details were directly revealed by the leak, the conventional brick-like shape of the batteries suggests the two newly spotted units are either meant to be used in the Snapdragon 845 variants of the Galaxy S9 and Galaxy S9 Plus or recent rumors about Samsung using a new integrated circuitry solution for the Exynos 9810 models of its upcoming Android flagships were false. If Samsung is to rely on a “Substrate Like” printed circuit board for any version of its next high-end mobile devices, the batteries found inside such units would be L-shaped, having a larger volume and hence offering more capacity than the newly leaked ones, which would also be the main reason for transitioning to such a PCB design in the first place.

Even if the Galaxy S9 series doesn’t end up improving on the battery capacity of the Galaxy S8 series, the two smartphones should still be able to deliver better performance on a single charge, primarily due to the fact that they’re expected to be powered by chips built on the second generation of Samsung’s 10nm FinFET technology, with both the Exynos 9810 and Qualcomm’s Snapdragon 845 thus being likely to offer an unprecedented level of energy efficiency in the mobile segment. The two flagships are scheduled to be officially announced on February 25th in Barcelona, Spain, and should start retailing by March 16th following a relatively short pre-order period, according to recent reports.
