Turbo 4
The Redmi Turbo 4 gives you near‑flagship speed, OIS‑stabilised 50 MP photos and a fast 90 W charge while staying under ₹40 k, making it the most balanced all‑rounder.
As of October 2026, the best phone under ৳40,000 in Bangladesh is the Redmi Turbo 4 at ৳38,499 on unofficial listings, in stock at 5 of the 16 shops we track when we last checked on 28 Oct 2026.

The Redmi Turbo 4 gives you near‑flagship speed, OIS‑stabilised 50 MP photos and a fast 90 W charge while staying under ₹40 k, making it the most balanced all‑rounder.
Redmi Turbo 4 wins because its Dimensity 8400 Ultra chip (CPU 9/GPU 9) gives flagship‑class performance and gaming while still offering OIS‑stabilised photos, 90 W charging and solid brand support.
Honor X9d trades some raw speed for a brighter 120 Hz display and a larger battery, so you lose performance and camera tuning compared with the Turbo 4.

Flagship‑class Dimensity 8400 Ultra + vapor‑chamber cooling give near‑top performance; massive 6550 mAh battery is efficient but not elite; HyperOS bloat and notification bugs hurt usability; camera tuning is inconsistent and ultrawide is weak. Scores are mined from published reviews and owner reports, not from our own testing.
Since 20 Jul 2026 the unofficial price has risen by ৳6,000. The lowest unofficial price we have recorded is ৳32,499.
Picks weigh five capabilities against the price, not any one of them. How we rank →

If you value a super‑bright 120 Hz AMOLED and a huge 8 300 mAh battery, the Honor X9d is the next best choice, though its chip is slower and its camera tuning is only average.

Samsung’s A37 shines with One UI’s low‑ad experience and the longest software‑support promise, but its mid‑range chip and modest 5 000 mAh battery keep it from leading the pack.

The POCO X8 offers a massive 8 340 mAh cell and decent 50 MP OIS camera, but its mid‑tier Snapdragon 6s and heavy ads make it a step down from the top two.

Realme P4 packs an 80 W charger and a 7 000 mAh battery, yet its lack of OIS and only average camera tuning hold it back from the leaders.
