Xiaomi Redmi 9 or iPhone 7: which is better to buy today? detailed comparison on 10 criteria

Choosing between the Xiaomi Redmi 9 (2020) and the iPhone 7 (2016) may seem strange: the first is a budget smartphone with modern โ€œstuffingโ€, the second is a six-year flagship from Apple. But in 2026, both devices are actively sold in the secondary market at a similar price (from 8 000 to 15 000 rubles), which makes the comparison relevant for those who are looking for an inexpensive phone with a balance of characteristics.

At first glance, the Redmi 9 is winning with fresh hardware: the MediaTek Helio G80 processor, 4/64 GB of memory, a quadruple camera and a 5020 mAh battery. But the iPhone 7 still holds on to the streamlined iOS, Apple's ecosystem and premium design. Who will win in real use? Let's take a look at the items โ€” from performance to durability โ€” and answer the question: should we overpay for the brand if the technical specifications are outdated?

In this article you will find:

  • ๐Ÿ”ฅ Comparative table of 12 key parameters (from screen to support updates).
  • ๐Ÿ“Š Performance tests: how both smartphones cope with gaming, social media and multitasking in 2026.
  • ๐Ÿ“ท Real examples of photos from the main cameras (daylight, night, portrait).
  • โšก Battery analysis: who lives longer on a single charge and how fast it charges.
  • ๐Ÿ’ฐ Buying Tips: What to Consider When Choosing a Used Model.

Take your time to conclude! For example, did you know that the iPhone 7 with iOS 15 does not officially support 5G, but some carriers (like Beeline) allow you to connect to the network through workarounds? And Redmi 9, despite its budget, has a microSD slot up to 512 GB โ€” a rarity for iPhones. Let's dig deeper.

1. Design and Ergonomics: Plastic vs Aluminum

At first glance, the iPhone 7 looks more premium: an aluminum case with anodized coating, symmetrical frames around the screen and a physical Home button (which, by the way, is no longer mechanical, but touch-sensitive with a tactile response). Redmi 9 is made of plastic with a texture under glass - this is both a plus (does not slide, does not beat), and a minus (collects prints, looks cheaper).

Both phones are compact in size, but the iPhone 7 is thinner (7.1 mm vs. Redmiโ€™s 9.1 mm) and lighter (138 g vs. 198 g). However, Xiaomi has the advantage of having a 3.5 mm headphone jack that the iPhone doesnโ€™t have (youโ€™ll have to use an adapter or wireless headsets).

  • ๐Ÿ“ Sizes: iPhone 7 โ€” 138.3ร—67.1ร—7.1 mm; Redmi 9 โ€” 163.3ร—77ร—9.1 mm.
  • ๐ŸŽจ Colors: iPhone has 5 options (including red and black); Redmi has 3 (gray, blue, green).
  • ๐Ÿ”‹ Protection: iPhone 7 has a class IP67 (Dust and moisture protection, Redmi 9 - only splash protection.

โš ๏ธ Note: If you drop your phone a lot, the Redmi 9 will survive the fall better thanks to the plastic case. But the iPhone 7 will withstand a short-term immersion in water (up to 1 meter for 30 minutes), which is not the same as the budget from Xiaomi.

2.Screen: Retina HD vs IPS with droplet

The comparison is not in favor of the Redmi 9. iPhone 7 is equipped with a 4.7-inch Retina HD IPS display with a resolution of 1334ร—750 (326 ppi), which is still considered the benchmark of color reproduction and brightness for its time. The screen supports 3D Touch technology (although it is almost not used in new iOS) and has an oleophobic coating that longer repels greasy traces.

Xiaomi Redmi 9 offers a 6.53-inch IPS LCD with a resolution of 2340ร—1080 (395 ppi) and a โ€œdropโ€ (cut out for the front camera).

  • ๐ŸŒˆ Color rendering: iPhone colors are more natural, Redmi โ€“ oversaturated (you can configure in the menu).
  • ๐Ÿ”† Brightness: maximum 625 nits for iPhone vs 400 nits for Xiaomi (in the sun the difference is noticeable).
  • ๐ŸŽฎ Update frequency: 60 Hz for both, but Redmi 9 has Reading Mode, which reduces blueness.

If you want a compact size and a high-quality picture, take the iPhone 7. If you need a large diagonal for video and games (even with the worst color reproduction) โ€“ Redmi 9.

The iPhone 7 screen is better in brightness and color reproduction, but the Redmi 9 offers a larger diagonal and high pixel density.

3.Performance: A10 Fusion vs Helio G80

On paper, the MediaTek Helio G80 in Redmi 9 looks more modern than the quad-core Apple A10 Fusion (2016), but real-world tests show a different picture:

  • ๐Ÿ“ฑ Single-core performance: iPhone 7 overtakes Redmi 9 in Geekbench 5 (about 800 vs 350 points).
  • ๐ŸŽฎ Games: On iPhone 7 PUBG Mobile launches on the โ€œBalancedโ€ settings (30) FPS), And on Redmi 9, on ยซHDยป (40 FPS). But the iPhone still holds. FPS steady.
  • ๐Ÿ”„ Multitasking: iOS 15 is optimized so that even 2 GB of RAM in the iPhone 7 is enough for smooth operation, while Redmi 9 with 4 GB of RAM can slow down when 10 open+ Chrome tab.

The iPhone 7โ€™s biggest asset is long-term support. Despite its age, it received iOS 15 (2021) and still gets security updates. Redmi 9 is stuck on MIUI 12.5 (Android 10) and is unlikely to get new versions.

โš ๏ธ Note: If you plan to use your phone for longer than 1-2 years, the iPhone 7 will last longer due to updates. Redmi 9 is already outdated and in a year may become unsafe (no patches for new vulnerabilities).

Results of the AnTuTu test (2026)
iPhone 7 (A10 Fusion): ~200,000 points.Xiaomi Redmi 9 (Helio G80): ~180,000 points.The difference is uncritical, but the iPhone shows better stability in the long run.

  • ๐ŸŒž Daylight: iPhone 7 transmits shadows better.
  • ๐ŸŒ™ Redmi 9 is a โ€œblotting outโ€ of details.

5. Battery and autonomy: 5020 mAh vs 1960 mAh

Here Xiaomi Redmi 9 wins unconditionally: the battery at 5020 mAh against 1960 mAh iPhone 7.

  • ๐Ÿ“ฑ Redmi 9: 2 days of moderate use (social networks, calls, 3-4 hours of screen).
