This device has a model number SM-E546B/DS and there are support pages for it on local Samsung.com sub-sites for Bangladesh, India and Levant. This device (listed under that same model number as well as SM-M546B/DS) also appeared in a certification by SGS Fimko.
The certification covers the battery system of the phone – 5,830mAh rated capacity, which will likely translate to 6,000mAh typical capacity. Also, the phone supports 25W fast charging (9V at 2.77A).
This is to be expected as the Galaxy M54 has this exact same battery and charging support. There may be some regional differences in the hardware for the F-series model, but there is no information on that yet.
The M54 is similar to the A54, though it is larger with its 6,000mAh battery (vs. 5,000mAh) and a 6.7” display (vs. 6.4”). It uses the same Exynos 1380 chipset, but features a higher resolution 108MP main camera (vs. 50MP, both with OIS).
With certifications in place and support pages already up, the Galaxy F54 should be close to launch. We haven’t heard anything yet, however, given the quiet launch of the M54, we are not expecting much fanfare.
