Redmi Note 17 Pro Max Review: The best mid-range battery life has a strong competitor in its own stable

For years, the Redmi Note series stood on a simple promise: a little more of everything than you’d expect for the money. The Redmi Note 17 Pro Max consciously breaks that promise for the first time. Xiaomi packed it with a 9,210 mAh battery, encased it in a body designed to survive a three-meter fall, and sacrificed performance and camera. The result is a phone that is best in its class in one discipline and worse than the model it replaces in two others.

Packaging: cable yes, charger no

We’ll quickly cover the box contents: phone, silicone case, SIM ejector tool, and a cable with USB-A and USB-C connectors. The 100W adapter is missing from the Czech package, even though Xiaomi includes it in other markets. Those who don’t have one at home will need to add a few hundred more.

Plastic that isn’t afraid of granite

The back and frame are plastic, with glass only on the front – Gorilla Glass Victus 2. This might sound cheap, but it has its justification. Plastic doesn’t crack and weighs less. Even so, the weight settled at 225 grams, noticeably higher than the Redmi Note 15 Pro+ with its 207 grams. The thickness of 8.65 mm, on the other hand, is unexpectedly modest for such a battery. A Samsung Galaxy A57, for example, is only 6.9 mm thick, but also has roughly half the capacity.

For the Czech model, Xiaomi states IP66 and IP68 protection with submersion up to two meters for 72 hours, and an SGS certificate for a three-meter drop onto granite. The display also responds to wet fingers, which I can confirm and is one of those features I would appreciate in competing (and often more expensive!) models.

The appearance will neither offend nor excite anyone. The only exception is perhaps the Cloud Blush variant I tested, whose back transitions from white to pink-orange in the sun. In my experience, two minor things detract from the ergonomics: the optical fingerprint reader is placed unnecessarily low, and the haptic feedback is only average. The infrared port for TV control remains.

A display that would suit even a more expensive phone

The AMOLED with a 6.83″ diagonal, 2772 × 1280 pixel resolution, and 120 Hz refresh rate is essentially the same panel Xiaomi uses in the POCO X8 Pro Max. The manufacturer promises 3,500 nits peak brightness. According to various measurements, the panel only reaches this briefly and on a small part of the surface. In normal viewing, automatic brightness reaches 1,100 nits, and manually you can set it to a maximum of 950. This is more than enough in direct sunlight.

The minimum brightness is pleasantly low, so reading in the dark doesn’t strain the eyes, and PWM dimming operates at a frequency of 3,840 Hz. Dolby Vision and HDR10+ are also present.

Performance: here Xiaomi backed down

Snapdragon 6 Gen 5 is a 4nm chip with four Cortex-A78 cores and four A55 cores. These cores are not new; we’ve seen them in phones for years. In Geekbench 6, I measured 947 points for a single core, which is less than the Redmi Note 15 Pro+ with Snapdragon 7s Gen 4. In the multi-core test, both phones are more or less equally powerful.

Benchmark	Redmi Note 17 Pro Max	Redmi Note 15 Pro+
Geekbench 6 – single core	947 points	1,240 points
Geekbench 6 – multi-core	3009 points	3,199 points
AnTuTu	821,475 points	954,658 points
3DMark Wild Life Extreme	1214 points	1,247 points

In my experience, the phone handles everyday tasks, but occasionally hesitates. Micro-stutters mainly occur when switching applications and in the camera, where the system can momentarily freeze. The good news, at least, is that the chip doesn’t overheat at all and doesn’t lose steam under load, maintaining 99% stability in the 3DMark stress test.

Storage is a chapter unto itself. Xiaomi states UFS 4.1, but according to my measurements, the speeds correspond more to UFS 3.1. Even so, it’s an improvement over UFS 2.2 in its predecessor. RAM is always 8 GB, even for the 512GB version.

Battery: the reason this phone exists

The silicon-carbon cell with a capacity of 9,210 mAh is 42% larger than in the Redmi Note 15 Pro+ and almost double that of the Galaxy A57. The global version even has a full 10,000 mAh, but Xiaomi sends a smaller variant to Europe.

In practice, this means one thing: you’ll stop worrying about the charger. According to my measurements, the phone lasts two days with heavy use and three days with more moderate use. Thanks to 27W reverse charging, it can also serve as a power bank for headphones or a second phone.

Charging is more complicated. One hundred watts sounds great, but the battery is enormous. With a 100W adapter, a full charge took me one hour and five minutes. More significant is the first fifteen minutes, after which the battery holds about a third of its capacity – roughly a full day’s worth of energy. Wireless charging is absent.

Level	30 %	50 %	80 %	100 %
Time	15 minutes	32 minutes	51 minutes	65 minutes

Xiaomi also promises that the cell will retain at least 80% of its capacity after a thousand cycles. Charging once every two to three days, this simple calculation works out to five to eight years.

Camera: from two hundred megapixels to fifty

Here, the concession is most evident. The predecessor had a 200Mpx main sensor, while the new model features a 50Mpx chip with a size of 1/1.95″, an aperture of f/1.5, and optical stabilization. Alongside it is an 8Mpx ultrawide camera with fixed focus and nothing else. A telephoto lens is missing, and fortunately, so is the unnecessary macro lens.

The main camera isn’t bad, though. In daylight, in my experience, it delivers images with decent detail and natural colors, but the processing sometimes overdoes it: sharpening is aggressive, HDR is weaker, and the sky can be overexposed. At night, thanks to its aperture and stabilization, the sensor performs well for its class, but in really poor light, details merge, and white balance can drift. A 2x crop is usable, but quality quickly drops from 4x zoom upwards.

The ultrawide camera is weak both day and night and only records in Full HD. Video from the main sensor maxes out at 4K at 30 fps; sixty frames per second are only available in Full HD. The 32 Mpx selfie camera is among the better ones.

HyperOS 3: Artificial intelligence in Czech

The phone runs on Android 16 with the HyperOS 3 overlay. Upon first startup, you’ll be greeted by Temu, Booking, TikTok, WPS Office, Amazon Music, and a games folder. Almost everything can be uninstalled, but for a phone costing twelve thousand, it feels undignified. Add to that notifications from system applications, which need to be patiently disabled during the first few days.

The HyperAI features deserve praise. Subtitles, speech-to-text, translator, and text generation work in Czech, which is still not a given with competitors. Gemini and Circle to Search are also available.

Xiaomi guarantees six years of security patches, i.e., until 2032. In addition, four major Android updates are expected. However, it starts with Android 16, not the newer Android 17. If we follow this logic, the most expensive Redmi will receive at most Android 20.

The biggest rival sits in the same stable

The official price is 12,499 CZK for the 8/256 GB version and 14,299 CZK for the 8/512 GB version. With an introductory code valid until October 18th, it drops to 10,699 and 12,499 CZK. On Heureka, the base version could be found just under ten thousand at the time of writing the review. Additionally, upon registration, Xiaomi adds one free display replacement within two years and one free battery replacement within three years.

The problem is that the POCO X8 Pro Max is in the same price list. It has the same sized display, a slightly smaller but still gigantic 8500mAh battery, 100W charging, the flagship Dimensity 9500s chip, 12 GB RAM, and 512GB storage. It officially costs 13,299 CZK, appears in stores for under twelve thousand, and weighs 218 grams. So, you’re essentially paying for an extra 700 mAh in the Redmi with performance that is several classes lower.

The smaller POCO X8 Pro offers roughly double the performance in benchmarks and costs under ten thousand, but it has a 6,500 mAh battery. The Samsung Galaxy A57 is tens of grams lighter, promises six years of system updates, and can be purchased for around 9,100 CZK in smaller stores. However, it cannot match the Redmi in terms of battery life or durability.

Verdict: a specialist, not a successor

The Redmi Note 17 Pro Max is not a continuation of the Redmi Note 15 Pro+. It’s a different phone under a similar name – a specialist that does one thing better than anyone else around and doesn’t hide what it sacrificed for it. Anyone who goes on multi-day trips, works outdoors, or simply hates searching for a cable in the evening will struggle to find better battery life at this price point. Two to three days of operation, a durable body, and an excellent display are arguments that cannot be argued against.

For everyone else, I would recommend slowing down. A weaker chip than its predecessor, eight gigabytes of RAM, a camera without a telephoto lens, and a system full of bloatware are not minor issues, especially when Xiaomi is competing with itself. A reasonable price starts where the official price list ends: around ten thousand, the Redmi Note 17 Pro Max makes sense; for the full 12,499 CZK, it does not.

Would you trade performance and a better camera for three days of battery life?
