Two of China's most talked-about value phones arrived within a day of each other in late October 2026. The Redmi K100 was announced on October 27 with a huge 10,000mAh battery, and the iQOO Neo12 followed on October 28 with a built-in cooling fan and a 185Hz screen. Both are big, flat, gaming-focused phones with 6.83-inch displays, 100W charging and simple dual cameras. The Redmi costs less, while the iQOO has the newer chip. Here is how they compare.

Design and display
Both phones are large and heavy. The Neo12 is slightly thinner and lighter, at 8.5mm and about 226g, while the K100 measures 8.65mm and weighs about 234.5g. Redmi lists a longer set of dust and water ratings, up to IP69K, but both phones are rated IP69 against high-pressure water jets.
The screens are the same size but take different approaches. iQOO uses a sharper 2K panel that refreshes at up to 185Hz. Redmi uses a 1.5K panel at up to 165Hz but claims more brightness. Sources don't agree on the K100's exact figure: GSMArena lists 3,200 nits peak, while Gadgets 360 and Chinese launch coverage quote 3,500 nits. Either way, it is well above the 2,200 nits iQOO claims for the Neo12, so the Redmi may be easier to read outdoors.
Performance and gaming
This is the iQOO's biggest advantage. The Neo12 runs the Snapdragon 8 Elite Gen 5, the same chip family found in the iQOO 15, and clocks up to 4.6GHz. The K100 uses the older Snapdragon 8 Elite at up to 4.32GHz.
Both brands add a separate gaming chip. iQOO's Q3 handles frame interpolation, upscaling to 2K and ray tracing in selected games, and iQOO says more than 50 games can run natively at 185fps. Redmi's D2 chip, made on TSMC's 12nm process, mainly handles frame interpolation so supported games can run at up to 165fps.
The Neo12 also has an active cooling fan inside, working with a vapor chamber of about 8,200 square millimeters. Chinese media cited lab tests presented at launch, but we haven't seen independent tests of either phone yet.
Cameras
Neither phone is built for photography. Both have a 50MP main camera with optical stabilization, a basic 8MP ultrawide and no telephoto lens, and both can record video at up to 8K/30fps. On paper, the K100's main sensor has a 1/1.55-inch size and a brighter f/1.68 aperture, while the Neo12 uses Sony's IMX921 at f/1.88. Source naming varies for the Redmi sensor: GSMArena calls it "Light Fusion 800" while Gadgets 360 calls it "Light Hunter 800", but both seem to refer to the same 50MP sensor. The Redmi also has the higher-resolution selfie camera, with 20MP against 16MP.
Battery and charging
Both phones have very large batteries. The K100 leads with a 10,000mAh silicon-carbon cell, and Xiaomi says it keeps at least 80% of its capacity after 1,600 charge cycles. The Neo12 has 9,000mAh, which is still far more than most flagships. Both charge at 100W by cable, and the Redmi adds 27W reverse wired charging, so it can top up other devices. Neither phone lists wireless charging in the launch specs we checked.
Keep in mind that the Neo12's higher refresh rate, sharper screen and fan may use more power, so the real gap in battery life could be bigger or smaller than the 1,000mAh difference suggests.
Software and updates
Both phones ship with Android 17: OriginOS 7 on the iQOO and HyperOS 4 on the Redmi, which includes Xiaomi's Super Xiao AI 2.0 assistant. The launch materials we checked did not state how many years of updates either phone will get.
Price
Both phones are currently sold only in China. Official list prices are:
- iQOO Neo12: CNY 4,399 (12GB + 256GB), CNY 4,799 (16GB + 256GB), CNY 5,099 (12GB + 512GB), CNY 5,499 (16GB + 512GB) and CNY 6,499 (16GB + 1TB).
- Redmi K100: CNY 3,499 (12GB + 256GB), CNY 4,099 (12GB + 512GB) and CNY 4,499 (16GB + 512GB).
Reports differ for the iQOO: GSMArena lists each model CNY 200 lower, starting at CNY 4,199, which matches the first-sale discount reported by Chinese media. Redmi is also running Double 11 promotions that cut the K100 to CNY 2,999 until November 11.
Which should you buy?
- Choose the iQOO Neo12 if gaming is your priority. It has the newer, faster chip, an active cooling fan, a sharper 2K screen at 185Hz and a 1TB storage option.
- Choose the Redmi K100 if you want the most battery for the money. It is cheaper, has a bigger 10,000mAh cell, a brighter screen, reverse charging and a better selfie camera.
Our take
For most buyers, the Redmi K100 is the better value. The older Snapdragon 8 Elite is still a powerful chip, and the bigger battery and lower price make it a very sensible pick. The iQOO Neo12 makes more sense for serious mobile gamers who will benefit from the fan, the faster chip and the 185Hz panel, and who are happy to pay extra for them. Neither brand has announced global versions yet, and past launches suggest that battery capacity can be smaller in some regions, so wait for regional specs before you decide.
