The Samsung Galaxy M42 is a phone that might launch with a 6000mAh battery
The Galaxy M40 is a phone that launched with an in-display selfie camera and a display-integrated speaker at the INR 20,000 (~US$268) mark in 2019. However, there was no corresponding M41, as you might expect, in 2020; Samsung seems to have passed it over in favor of the 7000mAh battery-toting M51 instead. Then again, this new device is in a slightly higher price tier.
Now, the OEM seems poised to launch an M42 in order to capture the sub-INR 25,000 segment again. A new certification for a battery called the EB-BM425ABY may be an indication that this is the case.
This, then, might be the M42, which is also rumored to have a 64MP sensor in its rear camera array. However, the number of lenses that might accompany it remain unguessed-at, as indeed do the rest of its specs.
Nevertheless, the reported appearance of its possible battery on the Chinese 3C and Indian BIS regulatory databases have led to speculation that the Galaxy M42 will make its debut in at least 1 of these jurisdictions soon.
