3. realme P4R 5G
Excellent battery-focused phone, but current Amazon/Flipkart prices are above ₹20K for the useful configurations, so I wouldn’t recommend it at today’s price. Flipkart
What I’d buy
If ₹20,000 is a strict maximum → POCO M8x 5G 4GB/128GB.
However, 4GB RAM is the compromise. If you can stretch to ₹21–22K, I’d rather look for a 6GB/128GB or 8GB/128GB phone.
If you want, I can do a fresh comparison of the best 5 phones actually available under ₹20,000 today on BOTH Amazon + Flipkart, including camera, processor, display, battery, software updates and gaming, and give you one final winner.
