You bought a new Xiaomi or you want to test the capabilities of an old smartphone, but you're not sure if it supports fast charging? This feature saves time, but not all models come with it — even if it comes with a powerful adapter. In this article, we'll look at how to know exactly the type of charging on your device without resorting to disassembly or risky experiments.
The manufacturer often points to fast charging in specifications, but in practice it is more complicated: some low-end models of Redmi or POCO can work with adapters at 18-33 watts, but only under certain conditions. Others, like the flagship Xiaomi 13 Pro, support 120-watt charging, but require the original cable and power supply, we will show how to test this yourself, from simple methods to deep analysis.
1. Verification through smartphone settings
The quickest way is to look at system settings. Most Xiaomi devices (based on MIUI 12-14) display charging information directly while connecting to the network.
- Connect your smartphone to the charger (preferably original or certified).
- Unlock the screen and swipe down to open the notification bar.
- Find the icon with the image of the battery – next to it should appear the inscription “Fast Charge”, “Turbo Charge” or “Quick Charge” (depending on the model).
If it doesn't, it doesn't always mean that there's no support. For example, on the Redmi Note 11, fast charging only happens when you use a 33W adapter. Some firmware also hides that information, and then the following method will help.
💡
On smartphones with MIUI 14 and later, you can see the current charging power in real time. To do this, tap the battery icon in the notification panel and hold it for 2-3 seconds.
Analysis of adapter and cable
Fast charging is not just smartphone-dependent, but component-based. Xiaomi's original adapters are power-marked (like 33W or 67W), but even if the power supply is high, it doesn't guarantee compatibility.
- 🔌 Adapter power: Check the lettering on the case (e.g. Output: 5V/3A, 9V/2A, 11V/3A). If the maximum value exceeds 10 Watt (5V/2A), The device probably supports accelerated charging.
- 🔗 Cable: Xiaomi’s original fast charging cables have thickened slat and labeling USB-C to USB-C (model USB-C). Older microUSB cables are usually limited to 10–18 watts.
- 📦 Package: If the box had an adapter of 18 watts or higher, the smartphone almost certainly supports fast charging. POCO M-series, where the adapter is separately.
For example, Xiaomi 12T Pro comes with a 120-watt adapter, but if you use a cable from the old Redmi 5, the maximum power will drop to 18 watts.

3. Use of diagnostic applications
If the system settings don't show charging information, third-party software will help. Applications like AccuBattery, Ampere or CPU-Z display current charging power, voltage and current strength. Here's how to use them:
- Install AccuBattery from Google Play (free version is sufficient).
- Connect your smartphone to charging and open the app.
- Go to the Charging tab, which displays a power graph (in watts) and a charge graph (in mA). If the values are greater than 10-15 watts, your device supports fast charging.
In Ampere, look at the settings Enter (on network connection) and Exit (on disconnection). For example, if you charge 1800 mA at 9 V, this corresponds to 16.2 W (fast charging).

4.Applying the smartphone model
Each Xiaomi model has fixed charging characteristics, which can be specified on the official website or in the specifications. Below is a table with popular devices and their support for fast charging (data is relevant for MIUI 14):
| Model | Max. Charging power. | Type of charging | Notes |
|---|---|---|---|
| Xiaomi 13 Ultra | 90 W. | HyperCharge | Requires original USB-C to USB-C cable |
| Redmi Note 12 Pro+ | 120 W. | Turbo Charge | Charges up to 100% in 19 minutes (according to manufacturer) |
| POCO X5 Pro | 67 W. | Fast Charge | The 67W adapter comes complete. |
| Redmi 10C | 18 W. | Quick Charge 3.0 | Supports only when using a compatible adapter |
| Xiaomi 12 Lite | 67 W. | Turbo Charge | Wireless charging – 50 W (optional) |
If your model is not in the table, check it on Xiaomi’s website (Specifications section) or GSMArena database. Note: some models (for example, Redmi 9A) support fast charging only in versions with the 5G or Pro suffix.
💡
Even if your model supports 33 watts, the actual charging speed depends on the battery temperature, CPU load and cable quality. When you use your smartphone actively while charging, the power can drop by 30-50%.
5. Test using engineering menu
For advanced users, there is a way to check through the Hidden Menu, which works on most Xiaomi devices, but requires caution – incorrect actions can disrupt the system.
Instructions:
- Open the phone app and enter the combination: ##4636##
- In the menu that opens, select Battery Information.
- Connect your smartphone to charging and watch for Status (should be Charging), Voltage (voltage) and Temperature (temperature).
- If the voltage is greater than 5V (e.g. 9V or 11V), your device uses fast charging.
⚠️ Warning: Do not change any settings in the engineering menu unless you are sure of their purpose.This can cause the battery to overheat or the firmware to fail. Also on some models (e.g. Xiaomi) 11T) Access to this menu is blocked.

6.Visual and indirect signs
Sometimes support for fast charging is indicated by indirect signs:
- ⚡ Sound signal: some models (e.g, POCO F4) Make a short sound when you connect a powerful adapter.
- 🔥 Heating the case: when charging fast, the smartphone can get noticeably warm (especially in the first 10-15 minutes).°C, it's better to turn off the device.
- ⏱️ Charging time: If the battery is charged from 0 to 50% in less than 30 minutes, accelerated charging is most likely used.
- 📊 Schedule in MIUI: In Settings → Battery → Battery usage can be seen on the charging schedule. A sharp rise in the level in the first minutes indicates high power.
However, these signs are not always accurate. For example, the Redmi Note 8 Pro warms up even when charging 18W, and the Xiaomi Mi 11 Lite can slowly charge due to firmware limitations.
7. Frequent errors and myths
There are many misconceptions surrounding fast charging by Xiaomi.
⚠️ Note: Using an adapter with power above the supported smartphone (for example, 120W for the Redmi 9, which only supports 18W) will not speed up charging, but may shorten battery life due to increased heat generation.
- ❌ Myth 1: “All Xiaomi smartphones with a USB-C support fast charging". ✅ Reality: Even with USB-C Budget models (e.g. Redmi) A1) limited to 10 watts.
- ❌ Myth 2: “Wireless charging is always slower than wired charging". ✅ Reality: Xiaomi 13 Pro supports 50W wireless charging – faster than wired charging from many competitors.
- ❌ Myth 3: If your smartphone is warming, it means that you are charging fast". ✅ Reality: Overheating can be caused by a faulty adapter or background processes. check power through apps!
Another misconception is that fast charging spoils the battery: Xiaomi’s current smartphones (starting with the MIUI 12) automatically reduce power when they reach 80-90% of the charge to extend battery life, but the constant use of cheap adapters can actually accelerate degradation.
