In terms of performance, the Redmi Note 12 is equipped with the Snapdragon 685 chip, which is well-known across many mid-range smartphones. This is one of the best Snapdragon 600 Series processors introduced by Qualcomm in 2023, delivering superior performance and better power efficiency compared to previous generations. Therefore, I believe the performance of the Redmi Note 12 can still meet the daily needs of users for the next 1 - 2 years.

Comparing the performance of Redmi Note 12 now to its debut 6 months ago, will the device still maintain its stability? To provide you with an overview, let's delve into the performance assessment of Redmi Note 12 after 6 months of use!
Performance Assessment of Redmi Note 12 after 6 Months of Use
To verify the performance of Redmi Note 12 at the current time, I will utilize common software such as GeekBench 6, 3Dmark, PCMark, and update the device to the latest MIUI version. The conditions for the assessment are as follows:
- The device battery is between 90 - 100% (battery below 90% may affect performance and results).
- No charging while assessing performance.
- Assess 3 times consecutively and take the average result after 3 assessments.

For GeekBench 6 and PCMark 10 applications, Redmi Note 12 delivers impressive results, closely matching some competitors in the same segment. The specific results are as follows:
- Geekbench 6:
- Single/Multi-core score: 455 points/1,456 points.
- GPU Compute: 382 points.
- PCMark 10: 7,113 points

Compared to the previous Geekbench 6 scores of 442 single-core and 1,303 multi-core points mentioned in the detailed review of Redmi Note 12, the current figures are slightly higher. This improvement could be attributed to the optimization of performance by the latest MIUI updates on Redmi Note 12, enhancing the efficiency of the Snapdragon 685 chip, resulting in smoother and more effective device operation.

Moreover, I also utilized the 3DMark Wild Life Extreme app to assess the graphics performance of the Redmi Note 12, yielding a score of 649 points, which remained relatively stable compared to previous evaluations. This indicates that the graphics processing capability of the Redmi Note 12 continues to be well-optimized.

Lastly, I conducted the most demanding stress test using the 3DMark Wild Life Extreme Stress Test. For those who may have forgotten, this test automatically repeats the scoring process up to 20 times to evaluate the stability of a smartphone under heavy usage over an extended period (such as video editing, gaming, etc.). You can view the results below and pay attention to assist me in assessing Stability.

Overall, the stability of the Redmi Note 12 after 6 months remains excellent at 96.9%. This is evidenced by the small difference between the highest loop score and lowest loop score, only 20 points (651 - 631 = 20), which is not significantly different from previous measurements. At the 6-month mark, the Redmi Note 12 exhibited a stability of 98.2% with a loop difference of only 12 points (652 - 640 = 12). Additionally, the device's temperature and battery life after 6 months showed minimal fluctuations during the test (temperature ranging from about 36 - 38 degrees Celsius, battery dropping from 99% to 96%).
Through these tests, I can tentatively confirm that the Redmi Note 12 still maintains good performance and stability at the current time. So besides its impressive performance, how does gaming on the Redmi Note 12 fare now? Let's continue exploring in the section below!
Redmi Note 12 still provides a good gaming experience after 6 months
At the time of its release, I had relatively good gaming experiences on the Redmi Note 12, so I expect the device to continue delivering similar or even better experiences after 6 months. In the gaming test section, I will experience four games including: Arena of Valor, Call Of Duty Mobile, League of Legends: Speed Chien, and PUBG Mobile. Additionally, I will use the Perfdog software to measure the FPS of each game, and the related data will be available here for your reference. Note that during the experience, I also use screen recording tasks, so the number of frames in the video may be affected.
- Arena of Valor:
For the game Arena of Valor, Redmi Note 12 still allows me to set the graphics options to high and maximum FPS as shown below:
In terms of gaming experience with Liên Quân Mobile on Redmi Note 12 after 6 months, I have nothing to complain about as the device maintains an average frame rate of about 50 - 55 FPS throughout the match. When performing actions like buying items, selling items, or casting skills, the frame rate remains very stable, with only a slight stutter during team fights. Additionally, the level of detail and imagery in the game are reproduced vividly and clearly by the device.
- Free Fire:
Moving on to Free Fire, a shooting game that relies heavily on frame rate stability. In this game, you can set the graphics to Very High, but in return, the frame rate is only set to Medium. However, to ensure optimal performance on Redmi Note 12, I only set the graphics to Low and push the frame rate to the maximum.

With such settings, the gaming experience with Call Of Duty Mobile on Redmi Note 12 is very stable, with an average FPS ranging from 55 to 59. Every action I perform in the game, such as shooting, throwing grenades, planting mines, running, etc., is smooth.
- League of Legends: Speed War:
In the MOBA game with heavy graphics settings like League of Legends: Speed War, Redmi Note 12 allows me to set the graphics to high and the maximum frame rate to 120 FPS. However, to reduce performance pressure, I only choose the 90 FPS option.

With the graphics settings as above, Redmi Note 12 impressed me as it could still maintain an average frame rate of about 60 FPS. Throughout the gameplay, I noticed fewer instances of lag even during intense battles. However, the device heats up quickly, so I suggest lowering the graphics settings slightly to keep the device cooler.
- PUBG Mobile:
For the renowned survival shooter game PUBG Mobile, I still set the graphics to Smooth with High frame rate on Redmi Note 12, similar to the options I had configured in the review when the device was newly launched.

Throughout the gaming experience, Redmi Note 12 continues to operate smoothly just like 6 months ago, with the frame rate fluctuating around 30 FPS. While in some instances such as sprinting, combat, or moving in areas with many buildings, Redmi Note 12 may stutter slightly but it doesn't significantly affect my gaming experience.
Concluding the game testing section, I'm still pleased with what the Redmi Note 12 can deliver after 6 months since its release, as the gaming performance remains solid just like the early days. The device's temperature only slightly rises after gaming for about 1 hour, so the Redmi Note 12 can still meet your entertainment needs at an affordable price.
Redmi Note 12 battery after 6 months can still handle continuous PUBG battles for nearly 8 hours
Besides demonstrating good gaming performance, can the 5,000mAh battery equipped on the Redmi Note 12 still provide long-lasting usage? With the 4 games in the test above, I'll check how long the device can handle extended gaming sessions! The specific conditions of the test are as follows:
- Play a single game until the device runs out of battery (from 100% to 0%).
- Screen brightness set to 100%, with 120Hz refresh rate enabled.
- External speaker on with volume set to 50%.
- WiFi and social media notifications enabled.
- No battery saver mode, adaptive display, GPS, and Bluetooth.
Here are the findings:

- League of Legends: Speed War: 5 hours 59 minutes.
- Mobile Legends: 5 hours 40 minutes.
- Call Of Duty Mobile: 6 hours 16 minutes.
- PUBG Mobile: 7 hours 45 minutes.
Overall, I'm pleasantly surprised that the 5,000mAh battery of the Redmi Note 12 can still provide gaming sessions exceeding 6 hours after 6 months. Among them, PUBG Mobile stands out with a runtime of 7 hours 45 minutes, indicating that the graphics settings applied to this game are optimized by the device. As for League of Legends: Speed War or Mobile Legends, the higher graphics settings I applied led to the device warming up quickly, resulting in more battery consumption. Therefore, to prolong device usage, you may consider reducing the game graphics settings slightly.
What's the price of Redmi Note 12? Is it still worth buying?
Currently, the Redmi Note 12 is available for purchase directly from Mytour at a price starting from 4.99 million VND (price may vary depending on promotional programs).
