Redmi 17 review: is R3,799 enough phone for South Africa's 4G-only future?

Xiaomi's Redmi 17 sells for R3,799 in South Africa, and for that money it offers a 6.9-inch 120Hz screen, a 7,500mAh battery and 45W charging. The buying question is narrower than the spec sheet suggests: is a 4G-only phone with 4GB of RAM and a 720p display the sensible way to spend under R4,000, at a time when Vodacom says its 3G network could be switched off within two years?

This is a verified briefing, not a hands-on review. SA Tech News has not tested a Redmi 17. The specifications below come from Xiaomi, the prices from Xiaomi South Africa's launch announcement and a live retailer listing, and the performance and charging figures from Stuff's review, which are its measurements, not ours.

Price and where to buy it

Xiaomi South Africa launched the phone on 11 September. The prepaid model, with 4GB of RAM and 128GB of storage, was priced at R3,799 at TFG stores, PEP, Takealot, Mr Price, Edgars, Incredible Connection and HiFi Corp. Incredible's listing still showed R3,799 on 30 October, with a two-year warranty.

Vodacom carries a 4GB/256GB version on contract from R349 a month. Xiaomi's announcement did not give the contract term, so the total cost of that deal is not clear from the launch material. Xiaomi lists the colours here as Black and Oak Green, subject to stock.

There is no charger in the box. Xiaomi's own specification page says so, and recommends its 45W adapter. Buyers moving from an old phone with a slow plug should budget for one, or accept slower charging.

The specifications, and what they mean

The processor is MediaTek's Helio G91-Ultra, an eight-core chip built on a 12nm process with a top speed of 2.0GHz and a Mali-G52 MC2 graphics unit. That is an older, modest design. Stuff's review recorded Geekbench 7 scores of 379 single-core and 657 multi-core, and noted that the benchmark identified the chip as MT6769V/CZ, a code it links to the older Helio G85. Xiaomi attributed that to the two chips sharing a core design.

Memory is 4GB of LPDDR4X RAM, which Xiaomi can extend with "virtual" memory borrowed from storage. Storage is eMMC 5.1, slower than the UFS storage in pricier phones, and there is a hybrid microSD slot that takes cards up to 2TB, at the cost of the second SIM.

The screen is a 6.9-inch LCD at 1,600 by 720 pixels, protected by Gorilla Glass 7i. It refreshes at up to 120Hz, which makes scrolling smoother, and Xiaomi rates it at 675 nits typical and 825 nits in high-brightness mode. The resolution is the compromise: on a panel this large, 720p text and photos are visibly softer than on a 1080p screen.

The rear camera pairs a 50MP main sensor at f/1.8 with an auxiliary lens; there is no ultrawide. The front camera is 8MP. Video tops out at 1080p and 30 frames a second on both.

The battery is 7,500mAh. Xiaomi South Africa quotes up to 28 hours of video, 91 hours of music and 46 hours of calls, which are its lab figures. Stuff recorded a full charge from empty in about an hour and 20 minutes on 45W. The phone can also charge another device over a cable at up to 22.5W, which makes it a stand-in power bank on a long trip.

It weighs 232g and is 8.8mm thick. The body is plastic, rated IP64 against dust and splashes but not immersion. There is a 3.5mm headphone jack, FM radio with wired earphones, Bluetooth 5.4, a side fingerprint reader and NFC, which Xiaomi South Africa lists for the local model. It runs Xiaomi HyperOS 3; Incredible's listing gives the Android version as 16.

Why the network bands matter here

The Redmi 17 is a 4G phone. Its global specification page lists LTE bands 1, 3, 5, 7, 8, 20 and 28, plus TDD bands 38, 40 and 41. Bands 20 and 28 are the 800MHz and 700MHz low bands that travel furthest from a tower, which matters outside the metros.

There is no 5G. At this price that is normal, and for many buyers outside 5G coverage it changes nothing today. It does shorten the phone's runway as operators move traffic to 5G over the next few years.

The more immediate question is 3G. Vodacom told TechCentral this week that its 3G network could be switched off in 12 to 24 months. A 4G phone keeps its data connection after that. Voice is different: calls on 4G rely on VoLTE. Xiaomi's specification page does not list VoLTE, and support can depend on both the handset and the operator. Buyers should ask their network to confirm VoLTE on this model before they buy.

Strengths and trade-offs

The case for the Redmi 17 is battery and value. A 7,500mAh cell with 45W charging is unusual under R4,000, and Stuff's reviewer found it lasted from morning to night. The 120Hz screen, headphone jack, FM radio, NFC and microSD slot cover the practical needs of a first smartphone or a work phone.

The case against is speed and sharpness. Stuff reported noticeable slowdown, especially while typing, and said the phone is not suited to serious gaming. Its reviewer also called the front camera weak and the video basic. The 720p panel is the main display letdown, and the phone is thick and heavy.

Xiaomi's pages that we checked do not state how many Android version updates or years of security patches the Redmi 17 will receive. For a phone many buyers will use for banking apps, that is a gap worth asking the retailer about.

What remains unresolved

We have not measured the battery ourselves, tested the camera in low light, checked call quality on South African networks or confirmed VoLTE behaviour on Vodacom, MTN, Telkom or Cell C. The Vodacom contract's term and total cost were not in the launch material. Xiaomi has not published a software support period for this model on the pages we checked.

Who should buy it, and who should wait

Buy it if battery life matters more than speed, if you want a big screen for video and messaging, and if R3,799 is the ceiling. It suits a teenager's first phone, a backup work phone or someone replacing an ageing 3G handset, provided VoLTE is confirmed on their network.

Wait, or spend more, if you play games, take a lot of photos indoors or at night, or want a phone to last four years with security updates you can count on. Over three years, the Redmi 17 works out to about R1,266 a year before a charger and data.

The last open point is the one that matters most as 3G winds down: whether this phone will make calls on 4G across all four networks. Xiaomi's specification sheet does not say.
