Xiaomi Redmi K40 — Full Specifications, Features & Price in Pakistan

The Xiaomi Redmi K40 is the 2021 sweet spot of the K-series: a Snapdragon 870 chip, a 6.67-inch 120Hz AMOLED with 1300-nit peak brightness, and a slim 196-gram body, launched in China in March 2021. Globally it was sold as the Poco F3, but Redmi K40-badged units in Pakistan are used China imports — this guide covers its verified specifications and the checks that matter before buying one second-hand.

Key Specifications at a Glance

Design and Build Quality

The K40 is notably slimmer and lighter than the K30 generation: 7.8 mm thin and 196 grams, with a centered hole-punch replacing the old pill cutout. Xiaomi sold it in White, Black and a shimmering Aurora finish. Build quality is solid mid-range — glass front, plastic-framed body — and the side-mounted fingerprint sensor doubles as the power button. On a used unit, check the hole-punch display for burn-in around the cutout and inspect the frame edges, which show wear first on this design.

Display Features

The 6.67-inch Super AMOLED runs at 120Hz with HDR10+ and a claimed 1300-nit peak brightness — a genuine flagship-grade panel for 2021, brighter than anything in the K30 family. At 1080 x 2400 (~395 ppi) with Gorilla Glass 5, it's sharp, smooth and readable outdoors. This display is one of the K40's strongest selling points on the used market: it embarrasses many newer budget phones' screens.

Processor and Performance

The Snapdragon 870 (7nm) is an overclocked Snapdragon 865+ with a 3.2 GHz prime core — effectively 2020 flagship performance refined, and famously efficient and cool-running. With the Adreno 650 GPU it handles demanding games at high settings and multitasking without breaking a sweat, and it ages better thermally than the Snapdragon 888 in the K40 Pro. For used buyers in 2026, the 870 remains one of the best price-to-performance chips you can get — powerful, stable, and free of the 888's heat reputation.

RAM and Storage

Configurations span 6GB, 8GB and 12GB of RAM with 128GB or 256GB of fast UFS 3.1 storage. There is no microSD slot, so pick your capacity carefully. The 8GB/128GB trim is the value sweet spot; 12GB/256GB suits heavy multitaskers and gamers who install large titles.

Camera Features

The triple rear camera is led by a 48MP f/1.8 wide sensor (1/2.0-inch, PDAF) — a step down in megapixels from the K30 family's 64MP, but a larger-pixel, more consistent shooter in practice. It's joined by an 8MP f/2.2 ultrawide (119 degrees) and a 5MP f/2.4 macro (50mm equivalent). Video reaches 4K@30fps with gyro-EIS. The 20MP f/2.5 hole-punch front camera handles selfies and 1080p video. This is a competent, no-drama camera system — not a camera flagship, but reliable.

Battery and Charging

The 4520mAh battery with 33W wired charging fills to 100% in about 52 minutes (advertised) over PD3.0/QC3. The efficient 870 chip and AMOLED panel help it stretch through a day. As always with used phones, verify battery health — a 2021 cell will have lost capacity, and replacements for a discontinued import aren't trivial to source.

Software and Updates

The K40 launched on Android 11 with MIUI 12. As a discontinued China-only Redmi model, official update support has ended — don't expect current Android versions or recent security patches. Confirm Google services and the Play Store work on the actual handset before paying, since China-ROM builds vary.

Connectivity and Additional Features

Network support is unusually broad for a China phone: 5G bands 1, 3, 28, 41, 77 and 78 (SA/NSA/Sub6) plus extensive LTE bands, so Pakistani 4G carriers are well covered. Also on board: Wi-Fi 6, Bluetooth 5.1, dual-band GPS with NavIC, NFC, an infrared blaster and USB Type-C 2.0 with OTG. Stereo speakers with Hi-Res audio certification sound good; the 3.5mm headphone jack is gone. There is no official water-resistance rating.

Variants, Colours and Availability

Xiaomi sold 6GB/128GB, 8GB/128GB, 8GB/256GB and 12GB/256GB versions in White, Black and Aurora. Globally, this exact phone was rebranded as the Poco F3 — one of the best-selling mid-rangers of 2021 — so Poco F3 listings are the same hardware under another name. The Redmi K40 badge itself was China-only and never officially launched in Pakistan, so local units are used imports.

Price in Pakistan and PTA Information

The Zohaan Mobile Gallery store lists the Redmi K40 at Rs. 61,999 (product page verified 2026-10-11). That's the store's catalog listing — used-import prices move with the market, so confirm the current price with Zohaan Mobile Gallery before deciding.

PTA warning: PTA approval is per device and IMEI, never per model. SMS the phone's IMEI to 8484 and confirm "Compliant" status before paying; also read how to check PTA approval and how to buy a used mobile safely.

Main Advantages and Limitations

• Slim 7.8 mm, 196 g body with stereo speakers
• Fast UFS 3.1 storage and 33W charging (52-minute full charge)

Limitations:

Who Should Consider This Phone?

Good fit: performance-per-rupee buyers who want a cool-running flagship chip, a bright 120Hz AMOLED and stereo speakers around Rs. 62,000 — gamers and heavy users especially, provided the unit passes inspection.

Look elsewhere if: camera quality is your top priority (the 48MP system is merely good), or you want current software and warranty — then compare options in the Xiaomi collection.

Frequently Asked Questions

What is the price of the Redmi K40 in Pakistan?

Rs. 61,999 as listed on the Zohaan Mobile Gallery store (verified 2026-10-11). Confirm the live price with the store, as used-import prices fluctuate.

Is the Redmi K40 the same as the Poco F3?

Yes — the Poco F3 is the global rebrand of the Redmi K40. Same Snapdragon 870, same display, same cameras.

Does the Snapdragon 870 overheat like the 888?

No. The 870 is known for running cooler and more efficiently than the Snapdragon 888 in the K40 Pro — one reason used buyers often prefer it.

What are its RAM and storage options?

6GB, 8GB or 12GB of RAM with 128GB or 256GB of UFS 3.1 storage. No microSD slot.

How good is its camera?

A 48MP triple rear camera with 4K@30fps video and a 20MP front camera. Reliable and consistent, but not a camera flagship.

Does it support 5G in Pakistan?

It has broad 5G band support (1/3/28/41/77/78), but Pakistani 5G availability is limited — buy it for its 4G performance and treat 5G as a bonus.

Is it available at Zohaan Mobile Gallery?

Check the Redmi K40 product page or WhatsApp +92 305 8452080 for current availability and price.

Final Verdict

The Redmi K40 is the used-market sweet spot of this series: Snapdragon 870 efficiency, a superb 120Hz AMOLED, stereo speakers and 33W charging at a Rs. 61,999 store listing. Its compromises are honest — a merely good 48MP camera, no headphone jack or microSD, and discontinued China-only status. Check the battery, the display and the IMEI, and it's one of the smartest performance buys in its price band.
