A leak pointing to a new Samsung smartphone battery with a 5830mAh battery may also imply the imminent launch of a device called the Galaxy M42. This putative phone is rumored to have a 64MP primary camera, and may be available in India soon.

Another Samsung I got: Samsung Galaxy M21 also has 6000 mAh which I got for Rs.12000 ($162) with exchange of old phone. 6000 mAh battery, UFS 2.1, 48 mp main+ultrawide+depth sensor, 128 GB storage. Great value for money.
A year ago, bought Samsung M30s for below INR10k, with exchange of Redmi 4, in festival offer, best purchase for me!
