Ulefone Armor 27T Pro+
The entry ticket to thermal imaging. A FLIR Lepton 3.5 sensor, a 10,600 mAh battery and 30 W wireless charging in a 441 g body.
The Ulefone Armor 27T Pro+ is a rugged 5G phone with a FLIR Lepton 3.5 thermal camera at 160×120 and 9 Hz, measuring from −10 °C to 450 °C with ±3 °C accuracy. It runs a MediaTek Dimensity 6300, has a 6.78-inch 120 Hz display under Gorilla Glass Victus, a 10,600 mAh battery with 33 W wired and 30 W wireless charging, a 50 MP main camera and a 64 MP night-vision camera, and weighs 441 g. Ulefone first listed it in February 2026.

Field verdictBuy it to find heat, not to measure it precisely. If thermal detail is the job, the 640×512 models are a different class of instrument.
What 160×120 means in practice
The FLIR Lepton 3.5 is a well-known module with a reliable calibration pipeline and FLIR's own app. Its limit is resolution. 160×120 is 19,200 thermal pixels; the ThermoVue T2 in the Armor 29 Pro Thermal and Armor 28 Ultra Thermal is 640×512, or 327,680 — about seventeen times as many. The 9 Hz refresh rate is also well below the T2's 25 Hz, so panning reads as stepped rather than smooth.
That still covers a lot of real work: finding which radiator is cold, spotting a hot breaker, tracing a leak under a floor, checking a pipe run or seeing an animal in the dark. Where it falls short is picking out which of several small, close components is hot, and measuring at distance. Ulefone states detection at 8 metres or more and at least two measurement spots per image.
Thermal cameras read apparent temperature. Shiny metal reads low, matte surfaces read close to true. If you need numbers rather than patterns, learn the emissivity setting in the app before trusting a reading.
The rest of the phone
Outside the sensor, the 27T Pro+ is a well-balanced mid-range rugged phone. The Dimensity 6300 gives it 5G; the 6.78-inch 120 Hz display is protected by Gorilla Glass Victus rather than the older Glass 5; and 30 W wireless charging is rare at this tier. Ulefone describes the battery as a solid-state cell that keeps working down to −30 °C, which matters for cold-store and winter outdoor work. At 441 g it is far lighter than the 21,200 mAh thermal model.
27T Pro+ or 27T+?
Ulefone released the Armor 27T+ at the same time. It keeps the FLIR Lepton 3.5 sensor, the 10,600 mAh battery, the 6.78-inch 120 Hz display and 30 W wireless charging, and swaps the Dimensity 6300 for a 4G Helio G99. If you do not need 5G, the 27T+ is the same thermal capability for less.
Reported weaknesses
Drawn from published reviews and aggregated owner reports across the Armor range, not from testing this unit.
- Thermal detailOwners moving from a 640×512 instrument find the Lepton image soft. Owners moving from no thermal camera rarely complain.
- Camera outputClose-focus and low-light results draw criticism across the Armor line.
- Call and microphone clarityA recurring Ulefone complaint. Test it inside the return window.
Alternatives
- Armor 27T+ — same FLIR sensor and battery on a 4G Helio G99.
- Armor 29 Pro Thermal — 640×512 and 21,200 mAh, at a much higher price and weight.
- Every Ulefone thermal phone compared.
Common questions
What thermal camera does the Armor 27T Pro+ use?
A FLIR Lepton 3.5 at 160×120 resolution and 9 Hz, measuring from −10 °C to 450 °C with ±3 °C accuracy, used through the MyFLIR Pro app.
Is the Armor 27T Pro+ thermal camera as good as the Armor 29 Pro Thermal?
No. The Armor 29 Pro Thermal uses a ThermoVue T2 at 640×512 and 25 Hz, about seventeen times the pixel count of the 27T Pro+'s 160×120 FLIR Lepton 3.5. The 27T Pro+ is lighter, has wireless charging and sits in a lower price tier.
What is the difference between the Armor 27T Pro+ and 27T+?
Both use the FLIR Lepton 3.5 and a 10,600 mAh battery. The Armor 27T Pro+ has a Dimensity 6300 with 5G; the Armor 27T+ has a 4G Helio G99.
Does the Armor 27T Pro+ have wireless charging?
Yes, up to 30 W with a stand sold separately, plus 33 W wired.
