Samsung Galaxy M17 5G: best screen and software support
At ₹18,999 against a listed ₹27,999, the Galaxy M17 is the pick for people who watch a lot of video. It has a 6.7-inch Full HD+ Super AMOLED display at 90Hz, Gorilla Glass Victus and an IP54 rating. The 50MP main camera has optical stabilisation, which is rare at this price. Samsung promises six years of OS and security updates, the longest promise on this list. The trade-offs are the older Exynos 1330 chip and a modest 25W charging speed.
Redmi 15C 5G and Redmi A7 Pro 5G: big screens, big batteries
The Redmi 15C 5G Prime Edition (₹17,999) pairs a 6.9-inch 120Hz display with a Dimensity 6300 chip, a 6,000mAh battery and a 33W charger in the box. If you want a large screen for reels and YouTube, this is the practical choice. The Redmi A7 Pro 5G is cheaper at ₹15,497 and has a 6,300mAh battery, but charging is only 15W and the camera is a 32MP dual setup, so treat it as a basic daily phone.
OnePlus N6x: biggest battery under ₹20,000
The OnePlus N6x has a 7,000mAh battery, the largest here, a Dimensity 6360 Apex chip and a 120Hz screen, plus an IP64 rating and MIL-STD-810H durability. The catch is the camera: a 13MP rear sensor is basic, and charging is limited to 15W. We have a separate deep-dive on its price, so see our OnePlus N6x Amazon Diwali sale price guide.
iQOO Z10 Lite 5G vs Z11 Lite 44W: which iQOO?
Both use a Dimensity 6300 chip. The Z10 Lite 5G (₹18,999) gives you a 6,000mAh battery, a 50MP Sony camera and a 6.74-inch 90Hz screen. The newer Z11 Lite 44W (₹19,497) adds 44W FlashCharge, a bigger 6,500mAh battery, a brighter screen (claimed 1,200 nits peak) and OriginOS 6, with a claimed AnTuTu score above 579K. For ₹498 more, the Z11 Lite is the better buy unless the Z10 Lite is discounted further with a bank offer. For more on iQOO's budget line, see the iQOO Z10x.
What about realme Narzo 80 Lite 4G?
At ₹11,998 it is the cheapest, with a 6,300mAh battery, IP54 and a 7.94mm body. But it only supports 4G. If you plan to keep the phone for three or four years, we would spend a little more for 5G.
Should you buy now or wait?
Buy now if you find a phone on this list at the price above, because sale prices tend to move up once the festive window closes. Also keep in mind that some brands have announced price increases from mid-November. For other budgets, read our guide to the best phones under ₹15,000 or compare with the realme P4x 5G and POCO X7 5G, which sit just above this budget. If you are unsure, see whether it is better to buy a phone this Diwali or wait for December launches.
