If your budget is 9000, you might as well add 999 more and get a brand new Realme C25 which has a 6000mAh battery, 18 watt fast charging, 4 GB RAM + 64 GB ROM and the MediaTek g70 processor. The g70 is better than snapdragon 662 which comes with Redmi 9 Power at a higher cost. You can check benchmarks on Google.. SD 662 hardly wins in 2-3 areas against g70.
Also, realmi fanfest is going on right now and you could participate and get ₹100 or even 300₹? discounts on your smartphone purchase.
