She asked me to shop for new phone for her as her old one is almost dead. Her budget is 12k.
Requirement: a decent camera for her daughter
Good battery back up
Known brand
Currently considering oppo k12x 5G at 13k( and with card discount 11.5k) and Vivo T4x 5G at 14k( 12.9k with discount) , tho would like if it's no more than 12k.
 
Strictly in that budget,
Poco M7 Pro 6GB
Moto G45 8GB
iQOO Z9X 6GB
All of 'em are one year old models. And don't expect too much from these phone wrt camera.

You be the judge whether to pay bit over your budget for this year model iQOO Z10X. With offers you can get it for 12750/-, price fluctuates so keep checking.

IMO a good nonsense option at under 15k (after CC discount), has big battery + close to stock android UI + 256GB storage (IMO 8/256GB is a must have now) + 3.5mm jack
Cons are slow charging & boots Android 14 (will get Android 15, if it hasn't already)

iQOO Z10x/vivo T4X 256GB will be 15.8k after CC discount, has slightly better performance, battery & charging with Android 15 to boot. Vivo's UI is not the best but will be ok (better than Xiaomi IMO).

For strictly near 12k, can also consider Realme Narzo 80x 8/128GB (obviously 128GB variant of above phones are cheaper as well), will be under 13k after card discount.
