Buy the realme C85 5G. These 2 phones run the same MediaTek Dimensity 6300, both spread 720p across a big LCD, and on 28 October their base models listed within Rs. 1,000 of each other: the Redmi 17C 5G at about Rs. 21,000 and the realme C85 5G at about Rs. 22,000. For that extra money the realme gives you 1,000mAh more battery, 45W charging against 33W, a 144Hz screen, NFC, and water protection rated for jets as well as dunks. The Redmi answers with a headphone jack, its own microSD slot, a lighter body and a written update promise that runs to Android 18. That is a real list, and for some readers it is the deciding one. For most, the realme is the better phone for Rs. 1,000.
Same engine. Different instincts.
Strip away the badges and these are 2 answers to the same brief. Both makers started from the Dimensity 6300 and a large 720p LCD, and both phones now sell for a little over Rs. 20,000. The difference is where each spent what was left.
realme spent it on endurance and armour. Xiaomi spent it on convenience and the long term. Neither choice is wrong. They just suit different people, and the trick is knowing which one you are before the money goes.
A word on how they arrived at the same price, because they came from opposite directions. The C85 launched last November at Rs. 15,499 and has climbed about Rs. 6,500 since, in a year when plenty of phones climbed after launch. The 17C launched this month at Rs. 20,999 and has not moved. So you are comparing a phone the market repriced with a phone that launched already repriced.
More tank, faster pump, thicker skin.
Battery and charging. 7,000mAh against 6,000mAh is 1,000mAh more, and 45W against 33W fills it faster too. Divide the watts by the capacity and the realme gets about 6.4W for every 1,000mAh, the Redmi about 5.5W. It also supports bypass charging, which powers the phone straight from the cable during long gaming sessions instead of cycling the battery.
Durability. This is the widest gap on the page. The realme carries IP66, IP68, IP69 and IP69K, which covers dust, submersion and high-pressure, high-temperature water jets, and realme says it passed a MIL-STD-810H shock test. The Redmi's IP64 is splash and dust protection. If your phone lives near water, a construction site or a toddler, this row alone decides it.
The screen, by a little. Both are 720p LCDs, so neither is sharp. The realme refreshes at up to 144Hz against 120Hz, and its 1,200 nits in high brightness mode beat the Redmi's 810 for reading outdoors in the afternoon.
NFC. The realme has it. Xiaomi does not list it for the India 17C. If you tap to pay, that settles it.
The things you miss only after they are gone.
The headphone jack. The Redmi has a 3.5mm socket. The realme does not. For anyone with good wired earphones, or a car that still takes an aux cable, this is not nostalgia, it is one less adapter to carry and lose.
Storage you can add. The Redmi takes a microSD card of up to 1TB in a slot of its own, so you keep both SIMs. realme's India page lists no card slot for the C85, and launch coverage describes a hybrid slot that takes the second SIM's place, so at best it is a card or a second SIM.
A written promise, and a later finish line. Xiaomi commits to 2 Android upgrades and 4 years of security updates for the 17C, starting from Android 16, so it should reach Android 18. realme publishes no update policy for the C85, which starts on Android 15. If you keep a phone 4 years, only one of these has told you what happens in year 3.
Lighter, slimmer, bigger. 211g and 7.99mm against 215g and 8.38mm, with a slightly larger 6.9-inch screen. Small margins, but they are all on one side.
Both are 720p at Rs. 21,000.
Spreading 720p across nearly 7 inches leaves both screens soft for reading. Neither lists optical stabilisation. Both record video at 1080p and 30fps at most. And neither is the most phone you can buy for the money: the POCO M8x 5G costs about Rs. 18,000 and pairs a newer Snapdragon 4 Gen 5 with 7,900mAh, 45W charging and 4 years of Android upgrades. Our POCO M8x 5G review makes that case, and our Redmi 17C 5G review explains why the 17C is the same hardware as last year's Redmi 15C 5G.
- Battery life and charging speed matter most
- Your phone gets wet, dusty or dropped
- You pay by tapping your phone
- You want the smoother, brighter screen
- You use wired earphones every day
- You want a memory card and 2 SIMs at once
- You want a written update promise and Android 16 out of the box
- A lighter, slimmer phone matters more than battery
The realme C85 5G wins. Same chip, both 720p, about Rs. 1,000 apart, and the realme turns that Rs. 1,000 into a bigger battery, faster charging, a 144Hz screen, NFC and the full set of IP66, IP68, IP69 and IP69K ratings. The Redmi 17C 5G is the right pick for a narrower reader: someone who uses wired earphones, wants a memory card alongside 2 SIMs, or values a written update promise over everything on the realme's list. Before you buy either, look at the POCO M8x 5G, which beats both on chip, battery and update promise, for less.
Rs. 1,000 more buys a lot more phone.
