Durable phone with a large battery and insanely fast charging got a big discount. It also captivates with its rear display

Durable phones with large batteries usually mean compromises in performance or display. However, the UleFone Armor 28 Pro tries to offer both – and now you can get it on Alza for 11,899 CZK with discount code ALZADNY15. This is a 2025 model that combines extreme durability with parameters you would typically expect from regular mid-range smartphones. If you want to check current availability, you can find everything directly in the product detail.

Quick summary:
✅ Makes sense if you work in the field, go on trips, or simply need a phone that can survive drops, water, and dust – and can also charge other devices.
⚠️ Consider if you prefer a compact and lightweight phone, or if low complaint rates are important to you – this model has a higher rate than usual.
💡 For 11,899 CZK, you get a 5G durable phone with a 10,600mAh battery, 120W charging, an OLED display, and 512 GB of storage – in the durable phone category, this is strong equipment for a reasonable price.

Why this phone is interesting

UleFone Armor 28 Pro targets users who need a phone for demanding conditions – and don’t want to give up modern features. The main draw is the 10,600 mAh battery, which in practice means two to three days of active use. The manufacturer states up to 576 hours of standby time, 58 hours of call time, and 14 hours of continuous video playback. Additionally, you can use the phone as a power bank for other devices – thanks to OTG reverse charging support.

Charging and Durability: Where the Armor 28 Pro Excels

Such a large battery would mean hours of waiting without fast charging. UleFone addresses this by supporting 120W wired charging, which is exceptional in the durable phone category. It also adds 50W wireless charging – something you won’t easily find among competitors in this price range either. However, it’s fair to add that the charging adapter is not included in the package, so if you don’t have a compatible charger with PD (PPS) protocol, expect an additional purchase.

Regarding durability, the phone meets IP68, IP69K certifications and the military standard MIL-STD-810H. In practice, this means resistance to submersion in 2 meters of water for 30 minutes, drops from 2 meters, dust, sand, and extreme temperatures. However, before contact with water, it is necessary to thoroughly close the port covers – the manufacturer emphasizes this, and it’s important to pay attention to it.

Display, Performance, and Cameras

The display is a 6.67″ OLED with 2400 × 1080 px resolution and a 120 Hz refresh rate. In ultra-bright mode, it reaches up to 900 nits (peak 2,200 nits), so readability in direct sunlight should not be an issue. An interesting feature is the 1.04″ AMOLED sub-display on the back in the style of a watch face – it serves to display notifications, control music, or as a viewfinder for selfies with the rear camera.

Under the hood runs a 4nm MediaTek Dimensity 7300 processor with eight cores clocked up to 2.5 GHz and 16 GB RAM (virtually expandable to 32 GB). Storage is handled by 512 GB of internal memory with the option to expand by up to 2 TB with a microSD card. The system runs on Android 15. For photography, there’s a 50Mpx main Sony IMX989 sensor, a 50Mpx wide-angle, a 64Mpx night vision camera with infrared LEDs, and a 50Mpx front camera. Also included are 5G, NFC, an IR blaster, and GPS/GLONASS/Galileo/BeiDou navigation.

What Users Say – and What to Consider

On Alza, the Armor 28 Pro has a rating of 4.2 out of 5 from 7 customers with 4 reviews. This is still relatively few ratings to draw definitive conclusions. Over 100 units have been sold, and 86% of customers recommend the product. Positive feedback primarily highlights battery life, performance, and overall durability.

However, a higher complaint rate of 7.37% is important, which Alza labels as “high.” For durable phones, this doesn’t necessarily mean a defective product, but it could be related to unrealistic expectations regarding water resistance (unclosed port covers) or the nature of a new model on the market. In any case, it’s a factor worth considering. The warranty is a standard 24 months.

Generally, for durable phones from Chinese production, software support and update speed are not usually on par with major brands. And with a weight of around 400–450 grams (due to the huge battery and armor), it is clearly a phone you will feel in your pocket.

If this particular model didn’t appeal to you, but you’re looking for a phone or accessory on sale, you can also browse the current Alza Days, where other discounted electronics offers regularly appear.

Verdict: Who it’s worth it for

If you need a phone that can survive construction, mountains, and rain – and at the same time want 5G, a large OLED display, and a two-day battery – for 11,899 CZK with code ALZADNY15, the Armor 28 Pro is an interesting choice. The combination of a 10,600mAh battery, 120W charging, and IP69K durability in this price category doesn’t have many competitors. On the other hand, if you prefer a light and compact phone, or if flawless software support and low complaint rates are important to you, it might be better to look at other models.
