I'm not a big expert in phones but, I think this will do for 2021. This phone has a massive 5000mAh battery, a 1.8 ghZ Octa- Core Snapdragon 652, 4GB of RAM, a small 32GB of storage fortunately, expandable storage upto 256GB, a decent 16MP camera which does pretty well in morning but, a lot of noise in the dark, Android 6.0 (Now for 2021 is 8.0), a 8MP front camera which does pretty well in morning but, a lot of noise in the dark, 6.0inch display (1080×1920), has NFC (Samsung Pay included), Dual SIM slot (both LTE) (4G not supported in India) and a 3.5mm headphone jack
