With a coupon, just 131 € in stock in the EU! Redmi 15 4G is the endurance king in the budget class: Massive 7000 mAh battery, smooth 144 Hz display, and built-in Gemini AI

Redmi 15 4G fits perfectly into the smartphone category that makes sense for a large group of users. This isn’t a model focused on extreme performance or a premium camera, but on practicality, battery life, and a reasonable price.

The biggest Xiaomi community in Slovakia

The main highlight is clearly the 7000 mAh battery, which doesn’t have many competitors at this price point. If you’re looking for a cheap phone for everyday use that won’t force you to search for a charger every evening, this is exactly the kind of device worth your attention.

Great price in EU stock with no waiting

You can get the Redmi 15 4G smartphone from a trusted seller on AliExpress directly in the European warehouse. That means very fast delivery within a week, with no extra fees. The seller offers a version with 8 GB RAM and 256 GB of internal storage, and it’s an official global smartphone version with all languages, including Slovak and Czech.

Buying on AliExpress for the first time?

This process is done through the AliExpress mobile app, where most people shop. Two things matter: don’t use Buy now and enter the coupon only in the order summary in the Promo code field. After you click Pay now, you can’t add it anymore.

1. Copy the code and click GET THE DISCOUNTIn our article, copy the coupon and click the button GET THE DISCOUNT. The link will take you directly to the product in the AliExpress app.
2. Use Add to cart, not Buy nowOn the product card, scroll down and click Add to cart. Don’t use the Buy now button—this skips the cart, so later you won’t have a place to enter the coupon. Before that, make sure the variant is correct: color, version, and whether it ships from an EU warehouse.
3. Continue to Checkout via the cartA pop-up will appear: Added to cart!—tap Check it out. If it disappeared, open the cart using the icon in the bottom-right corner. In the cart, check the product and quantity, then tap the red Checkout button. Only the items marked with the red circle are included.
4. Fill in your address and card, then look for Promo codeIn the order summary, first enter the delivery address and payment card at the top. Below that, there’s a line Promo code — expand it with the arrow on the right.

   

5. Paste the code and confirm ApplyIn the field Promo code paste the copied code and click the black Apply. The code is case-sensitive and must not contain spaces.

   

6. Check your savings and payIn the section Summary expand the line Saved — you’ll see the applied coupon there as AliExpress coupons/codes. Only when Total is really lower, click Pay now.

   

Apply the discount again in the order summary. After you click Pay now, you can’t add a coupon anymore. If Apply shows an error, the code has either expired, doesn’t apply to your item, or your order doesn’t meet the minimum amount.

Store Coupon also belongs in the same field. — a coupon from the seller itself, which isn’t always available and changes day to day. It can’t be combined with an AliExpress coupon, so try both and go with the one that gives you more. Coins are added automatically.

A massive battery as the main weapon

The biggest advantage of the Redmi 15 4G is, without a doubt, its 7000 mAh battery capacity. In practice, that means two to three days of regular use without any stress. If you mainly use the phone for calls, messages, social media, and the occasional video, getting to more than three days isn’t a problem. For people who are often on the go—or simply don’t want to deal with daily charging—this is a huge plus.

The battery supports 33 W fast charging, which is very important for a battery of this size. Charging isn’t record-breaking fast, but it’s still a sensible compromise between speed and preserving the battery itself. Keep in mind that there’s no charging adapter included in the box, so it’s best to use an original Xiaomi charger.

A big 144 Hz display for everyday use

The front is dominated by a large 6.9-inch FHD+ display with a resolution of 2340 × 1080 pixels. One interesting feature is the refresh rate of up to 144 Hz, which you’ll especially appreciate when scrolling, browsing the web, or using supported apps. The display looks smooth and snappy—something that isn’t always a given in this price category.

The maximum brightness reaches 700 nits, and in HBM mode up to 850 nits, so readability in daylight is solid. You’ll also appreciate the TÜV Rheinland certifications for reduced blue light, flicker-free technology, and circadian-friendly care—pleasant especially for longer evening use.

Snapdragon 685 performance is a sensible compromise

Performance is handled by the Snapdragon 685 chipset made using a 6 nm process. It’s not a gaming chip, but for everyday use it’s more than enough. The phone smoothly switches between apps, handles social media, YouTube, and navigation without major issues. There are configurations with 6 or 8 GB RAM and storage up to 256 GB.

A big advantage is the option to expand memory with a microSD card up to 2 TB, which still isn’t completely common these days. There’s also virtual RAM expansion, which can help with multitasking if you have enough free storage.

A camera without pointless promises

The Redmi 15 4G is built around a 50 MPx main camera with an f/1.8 aperture. Daytime photos look decent, with good colors and enough detail for everyday use. It’s not a camera phone, but for social media or quick shots it’s more than sufficient.

Night photos are rather average, which you can expect at this price. The front 8 MP camera will handle video calls and selfies, and it also supports HDR and portrait mode. Video is limited to 1080p at 30 fps, which is again standard for this class.

Connectivity, durability, and included features

The phone supports all the key LTE bands including B20, NFC for contactless payments included, Bluetooth 5.0, and dual SIM in a hybrid slot. There’s also a side fingerprint sensor with face unlock. Bonus: an IR blaster you can use as a remote control.

The build meets IP64 certification, so the phone handles dust and water splashes. It runs on Xiaomi HyperOS 2, bringing a modern interface and optimization for a large battery.
