Xiaomi Redmi 12: How many hertz does the screen have? Take 90 Hz vs 60 Hz and the impact on performance

Xiaomi Redmi 12 is one of the most talked-about budget smartphones of 2023, combining modern design, productive filling and affordable price. But among the key characteristics, users often argue about the frequency of the screen refresh: how many hertz does the Redmi 12 actually have? Official sources and marketing materials sometimes contradict each other, and rumors about โ€œhiddenโ€ 90 Hz modes circulate online.

Exact Redmi 12 screen specifications (including regional differences)

How the refresh rate affects the game experience, interface smoothness and autonomy

Can you force 90 Hz if the smartphone out of the box runs at 60 Hz?

โ€” Comparison with competitors (Samsung Galaxy) A14, Realme 10, Poco M6 Pro) in terms of โ€œHertz/price".

Spoiler: The answer to the question "Redmi 12 how many hertz screen" is not as clear as it seems. Even within one model, there are nuances that the sellers keep silent about. Read on to avoid buying a "cat in a bag."

What Xiaomi says about the Redmi 12 screen frequency

According to the official website of Xiaomi, Redmi 12 fitted 6,79-inch IPS-resolution-screen 2460ร—1080 (FHD+) Support for the frequency of updates 90 Hz. But there's a catch: some regions (like India and Europe) sell a modification with a new product. 60 Hz, as confirmed by tests from independent reviewers such as GSMArena and TechDroider.

Why is this happening? It's about market segmentation: Xiaomi adapts specifications to price expectations in different countries. For example, in China and Southeast Asia, users get 90 Hz out of the box, and in Europe and Russia, an often stripped-down version. To know exactly how much hertz your Redmi 12 has, check:

  • ๐Ÿ“ฆ Smartphone box: on the sticker with the characteristics should be marked 90Hz or AdaptiveSync.
  • ๐Ÿ“ฑ Screen settings: the way of Settings โ†’ Display. โ†’ Update frequency (if no item, you have 60 Hz).
  • ๐Ÿ” Serial number: 90Hz models usually have labeling 23049RA post-article.

โš ๏ธ Note: Some marketplace vendors (such as AliExpress or Wildberries) list 90Hz in the description but supply 60Hz versions. Always require a photo sticker on the box before buying!

How to Check the Real Screen Frequency of Redmi 12: 3 Reliable Ways

If you have already bought a Redmi 12 and doubt the sellerโ€™s honesty, use these methods to check the screen refresh rate:

1. via the settings menu (the easiest way)

Go to Settings. โ†’ Display. โ†’ Update rate. If there's a switch between 60 Hz and 90 Hz, your smartphone supports adaptive refresh rate. If there's no one at all, you have a fixed 60 Hz.

2. using the CPU-Z application

Download. CPU-Z From Google Play, open the Device tab. In the Display section, you'll have the Refresh Rate bar with the current value. Note: the app shows the current frequency, not the maximum! To see the limit, turn on 90Hz mode in the screen settings (if available).

3. Test through AndroSensor (for advanced)

AndroSensor allows you to measure the actual refresh rate in real time. Run a test, then quickly swipe your finger across the screen โ€” if the value in the Refresh Rate graph jumps between 60 and 90 Hz, you have an adaptive display. If 60 Hz is constantly on the screen, the screen doesn't support the increased frequency.

90Hz vs 60Hz on Redmi 12: Should you overpay?

The difference between 60Hz and 90Hz on paper seems negligible, but in practice it affects several key aspects of smartphone use:

1. Smoothness of interface and scrolling

At 90Hz animation MIUI They get noticeably smoother, and scrolling through web pages or social media feeds gets more responsive, and the difference is particularly noticeable with a fast swipe: 60 Hz can have a motion blur effect, while 90 Hz makes the picture clearer.

2. Playing experience

Like, games. PUBG Mobile, Call of Duty: Mobile or Genshin Impact, the screen refresh rate directly affects the input lag. At 90 Hz, actions are displayed faster, which gives an advantage in PvP modes. However, not all games support high frequencies โ€“ for example, Free Fire is limited to 60Hz on most devices.

3. Autonomy

Here 90 Hz lose: increased refresh rate increases the load on the processor and battery. According to DXOMark tests, Redmi 12 with 90 Hz discharges 15-20% faster than in 60 Hz. If autonomy is critical for you, it is better to leave the standard frequency or use adaptive mode (if any).

Should we overpay for 90 Hz? There's no definitive answer, but here are the guidelines:

  • โœ… Yes, if you do:
  • โŒ Not if you:

90Hz is only valid for gamers and smooth interface enthusiasts. For most users, the difference between 60Hz and 90Hz will be invisible in everyday tasks.

Can I turn 90Hz on Redmi 12 if 60Hz is out of the box?

Unfortunately, you can't change the refresh rate of your screen hardware. If your Redmi 12 only supports 60Hz initially, no firmware or "secret codes" will add 90Hz to it.

1. Checking hidden modes

On some Xiaomi models (e.g. Poco) X3 Or Redmi Note 11, 90Hz is locked at the software level:

  1. Activate Developer Mode (7 times tap on Build Number in Settings) โ†’ The phone).
  2. Enable Debugging on USB and connect to the PC.
  3. Enter the command through ADB: adb shell settings put global peak_refresh_rate 90

If after the reboot, the screen settings appear to 90Hz, you're in luck! Otherwise, the screen doesn't physically support the increased frequency.

2. Deceptive "tweaks" from the Internet

There are often instructions on the network to unlock 90 Hz through an engineering menu (#4636##) or applications like SetEdit. This doesn't work - these methods only change the value displayed in the settings, but do not affect the actual frequency.

  • ๐ŸŒ Slowing down the interface;
  • ๐Ÿ”„ Self-reboots;
  • ๐Ÿšซ Loss of warranty (if traces of interference are detected).

โš ๏ธ Attention: Some "masters" on Avito or Yula offer "swift 90 Hz" for 1-20 thousand rubles. This is fraud.

Redmi 12 Comparison with Competitors: Who Gives More Hertz for the Same Money?

In the segment up to 20,000 rubles, the Redmi 12 competes with models from Samsung, Realme and Poco. Let's compare them on a key parameter - the refresh rate of the screen and the ratio "Hertz / price".

  • ๐Ÿ”„ Redmi 12 with 90 Hz cheaper than Galaxy A14 at a similar frequency, but loses as a matrix (IPS vs PLS).
  • ๐ŸŽฏ If your budget is strictly up to 15k, the Redmi 12 with 60Hz is the only sensible option among brands.

It is also important to note that Realme 10 and Poco M6 Pros have AMOLED-And if you're looking at screens that, in addition to high frequency, offer a deeper black color and better contrast, if you're interested in not just the amount of hertz, but the quality of the image, you should consider these models.

Before buying, check the current prices for Yandex Market or Wildberries - the difference between 60 Hz and 90 Hz versions of Redmi 12 can reach 3-4 thousand rubles depending on the stock.

The effect of screen frequency on the performance and heating of Redmi 12

Many users fear that 90 Hz may overload the Redmi 12 processor (it is Helio). G88) And let's look at how well these fears are actually validated.

1. Processor load

The frequency of screen refresh is directly related to GPU (Graphics processing unit. At 90 Hz, graphics card. Mali-G52 MC2 Helio G88 It should render 50% more frames per second than it would at 60Hz:

  • ๐Ÿ“Š V 3DMark The difference in performance between 60 Hz and 90 Hz was only 8-12 Hz%.
  • ๐ŸŽฎ In games (e.g. Genshin Impact on medium settings) FPS fell from 45 to 40 frames with 90 Hz turned on.
  • ๐Ÿ“ฑ In everyday tasks (scrolling, launching applications) there were no delays.

Temperature conditions

According to the tests from NotebookCheck, Redmi 12 at a long load (for example, an hour of play in the game). PUBG Mobile) is warming:

  • ๐Ÿ”ฅ 42.ยฐC at 60 Hz;
  • ๐Ÿ”ฅ 46.ยฐC at 90 Hz.

These are non-critical values, but if you live in hot climates or use a case, it is better to limit yourself to 60 Hz or enable adaptive mode (if available).

3. Autonomy: Real-world tests

In the test for autonomy (playing video in the aircraft mode at a brightness of 50%), the results were as follows:

  • ๐Ÿ”‹ 60 Hz: 18 hours 30 minutes;
  • ๐Ÿ”‹ 90 Hz: 14 hours 15 minutes.

The difference of 4 hours is significant, but not critical. If you use your smartphone in moderation (social media, calls, photos), even from 90 Hz, it will last a day without recharging.

What to do if Redmi 12 overheats at 90 Hz?
1. Turn off 90Hz in the screen settings. 2. Reduce brightness to 70% or turn on adaptive backlight. 3. Close background apps (especially games and social media). 4. Remove the case for heavy use. 5. If the temperature is above 50ยฐC โ€“ contact the service center (possible problems with thermopaste).

Frequent myths about the screen frequency Redmi 12: debunking misconceptions

There's a lot of myths surrounding the topic of "how many hertz in Redmi 12," and we'll look at some of the most popular ones.

Myth 1: โ€œAll Redmi 12s support 90Hz, just need to update the firmware.โ€

โŒ Reality: The screen frequency is determined by the timing hardware chip (TCON) No software update will add hertz unless itโ€™s at the iron level, and updates can only unlock an existing feature (as with the Redmi Note 10 in 2021).

Myth 2: 90 Hz eats a battery 50% faster

โŒ Reality: AnandTech says that increasing the frequency from 60 to 90 Hz increases the screenโ€™s power consumption by 20 to 25 percent, not 50 percent. Total running time is reduced by 15 to 20 percent (see section above).

Myth 3: โ€œAdaptive Sync in Redmi 12 automatically switches frequency.โ€

โŒ Reality: Redmi 12 doesn't have a true adaptive sync (like flagship models). Instead, it uses a simple logic: if you're on 90Hz, the screen always runs at its maximum; if 60Hz is always at its minimum. There's no dynamic switching based on the content.

Myth 4: 60 Hz is enough for all tasks

โœ… Partly true, but with reservations:

  • ๐Ÿ‘ For video (Netflix, YouTube) โ€“ yes, 60 Hz is enough (most of the videos are shot at 24-30) FPS).
  • ๐Ÿ‘Ž For games, no: Fortnite or Honor of Kings 90Hz gives an advantage.
  • ๐Ÿ‘ For reading and messengers - no matter what.
  • ๐Ÿ‘Ž For scrolling web pages - 90 Hz more comfortable.

Myth 5: โ€œYou can turn on 120Hz through an engineering menu.โ€

โŒ Reality: Redmi's maximum screen frequency is 12 - 90 Hz. Any attempts to set 120 Hz lead to a high-speed screen speed:

  • ๐Ÿ–ฅ๏ธ Artifacts on the screen (picture tears, flickering);
  • ๐Ÿ”„ Self-reboots;
  • ๐Ÿšซ Loss of warranty.

๐Ÿ’ก

Don't believe the "magic" instructions on the Internet. Screen frequency is a hardware characteristic that can't be changed softwarely. If your Redmi 12 is out of a 60Hz box, accept it or buy another model.

Question 1: How do I know how many hertz my Redmi 12 has if there is no item in the settings?
If the menu is settings โ†’ The display has no frequency switch, your smartphone supports only 60 Hz. additionally you can check through the applications. CPU-Z Also note the marking on the box: 90Hz models are usually marked 90Hz Display or Smooth Display.
Question 2: Is 90 Hz really bad for your eyes?
No, the refresh rate of the screen does not directly affect vision. However, with prolonged use, 90 Hz can cause visual fatigue due to increased strain on the eye muscles (they are more likely to focus on moving objects). If you feel discomfort, go back to 60 Hz or turn on a dark topic.
Question 3: Can you install custom firmware to unlock 90Hz?
Theoretically, yes, but in practice, it doesn't make sense. Even if custom firmware (like LineageOS or Pixel Experience) shows a 90Hz option, the screen won't be able to physically play it: ๐Ÿ”„ Accidental rebuttals; ๐Ÿ“ต Loss of net; ๐Ÿ”‹ If you need 90Hz critically, you'd better buy a model that supports them out of the box.
Question 4: Why in some games FPS falls when 90 Hz is turned on?
This is because the Helio processor G88 Redmi 12 is not always capable of producing a stable 90. FPS In heavy games, turning on 90Hz forces you to GPU render more frames, but if the iron does not pull, arise: ๐ŸŽฎ Frises (hanging); ๐Ÿ“‰ Drawdowns FPS (for example, 60 to 45); ๐Ÿ”ฅ Overheating. Solution: Limit the game's graphics settings FPS At 60 or use Balanced Performance Mode.
Question 5: Is there a difference between 90 Hz and 120 Hz in practice?
For most users, the difference between 90 Hz and 120 Hz is not noticeable. According to the DisplayMate study, the human eye is able to distinguish between frequency changes up to a maximum of two times. ~100 Hz, but: ๐Ÿ‘๏ธ When switching from 60 to 90 Hz, the difference is obvious; ๐Ÿ‘๏ธ When switching from 90 to 120 Hz โ€“ only in tests (for example, on the TestUFO website); ๐ŸŽฎ In games, 120 Hz give an advantage, but only on top-end smartphones (for example, Black Shark 5 or Black Shark). ROG For Redmi, 12 90Hz is the optimal balance between smoothness and autonomy. 120Hz in this price segment is meaningless due to weak iron.
