How to know if there is fast charging on your Xiaomi: proven methods

You bought a Xiaomi smartphone and you wonder if it supports fast charging technology, or maybe your old phone suddenly starts charging slower than before? In this article, we will look at all the ways to determine the type of charging, from visual inspection of components to software tests. It is important to understand that even if the smartphone technically supports accelerated charging, its real speed depends on three factors: device model, adapter power and cable quality.

The manufacturer doesn't always clearly specify this information in specs, especially on budget models, and some vendors are even misleading to pass off standard charging as "fast." We've put together 7 reliable verification methods that work for all Xiaomi, Redmi and POCO lines, from flagships to the most affordable devices, starting with the simplest.

Verification of markings on the power adapter

The quickest way is to look at the power supply that came with the smartphone, and the manufacturer will specify the protocols supported and the maximum power.

• 🔌 Quick Charge (QC) — standard from Qualcomm (for example, QC 3.0 or QC 4+). It is available on most Xiaomi models until 2020.
• ⚡ Fast Charge – Xiaomi’s own technology (usually 18W, 27W, 33W or above. Marked as MI Fast Charge.
• ⚡⚡ HyperCharge / TurboCharge - advanced protocols for flagships (from the Internet) 67W before 210W). It is available on Xiaomi 12 Pro, Redmi Note 12 Turbo and newer.
• ❌ 5V/1A or 5V/2A — standard charge (maximum) 10W). It's not fast.

Note the output power (output) in the V/A. For example, 9V=2A or 10V=3A stands for fast charging (18W and 30W respectively), if you see only 5V=1A, that's normal charging.

⚠️ Note: Some Chinese adapters without a brand can mimic the fast charging marking, but in fact issue standard ones. 5W. Check the real power through the apps (more on that below).

2.Smartphone model analysis: compatibility table

If you lose an adapter or use a third-party adapter, you can determine support for fast charging using the device model. We have compiled a table with current data for popular Xiaomi lines (2018-2026).

If your model is not in the table, check the official specs on Xiaomi’s website (Specifications → Battery).Look for lines like Fast charging or Quick Charge. Note: some models (such as the Redmi 9A) do not support fast charging at all, even if the specs say 10W is standard power.

3. Test of charging speed through applications

The most accurate method is to measure the actual charging speed with specialized utilities, and we recommend two applications:

1. AccuBattery (Play Market) -- shows real-time charging current, battery temperature and battery health score. Look for the Charging tab.
2. Ampere (Play Market) – displays current in milliamperes (mA). For fast charging, values must be above 1500-2000 mA.

How to run the test:

1. Discharge your smartphone to 10-15%.
2. Connect the original adapter and cable.
3. Run the application and watch the indicators in the first 10 minutes (maximum current is achieved at a low charge level).

The results are deciphered as follows:

• 🔥 >3000 mA – ultra-fast charging (67W+).
• ⚡ 1500–3,000 mA – fast charging (18W–33W).
• 🐢 500-1500 mA – standard charging (5W–10W).
• ❄️ <500 mA – slow charging (possibly a problem with cable or adapter).

⚠️ Note: If the test current jumps from 500 to 2000 mA, it is a sign of a worn battery or an unoriginal cable.

4. Visual signs of fast charging on screen

Many Xiaomi smartphones display a charging type notification right on the lock screen or in the status bar.

• 📱 Fast charging, Turbo charging or HyperCharge under the battery icon.
• ⚡ Lightning icon (⚡) Next to the percentage of charge (on some firmware) MIUI).
• 🔋 Animation of charging with accelerated battery filling (in the first 30 minutes the level rises by 50-70%).

If there are no such indicators, this does not always mean that fast charging is not available – some models (for example, the POCO X3 Pro) do not show notifications, but support 33W. In this case, combine this method with others (see the section on applications).

On MIUI firmware 13/14, the path to the charging display settings is: Settings → Battery → Battery settings → Charging animation style. Here you can turn on real-time power display (Option Show Charging Current).

5. Check through the Engineering Menu (for advanced)

If you're confident in your actions, you can look at the engineering menu of your smartphone. This method is suitable for all devices on Qualcomm Snapdragon (most Xiaomi/Redmi/POCO).

1. Open the phone app and dial the combination: ##4636##
2. Go to the Battery Information tab.
3. Note the lines: AC powered – connected to the network; USB powered – connected to USB (slower); Status: Charging (AC) – is charging from the adapter; Voltage and Temperature – voltage and temperature.

6. Charging time comparison: a practical test

If you don't have any apps on hand, you can actually estimate the charging speed by eye by full cycle time. Take a stopwatch and see how much it takes to charge from 0% to 100% when the screen is off. Compare it to the reference values:

Keep in mind that real time depends on battery status, ambient temperature and smartphone load, for example, if you're playing games while charging, the speed can drop by 30 to 40 percent.

• 📵 Turn off mobile internet and Wi-Fi;
• 🔕 Put your phone in "Do Not Disturb" mode";
• 🌡️ Check the battery temperature (optimum - 20-30)°C).

💡

If the smartphone is warming above 40°C, the fast charging automatically shuts down for safety. Let it cool for 10-15 minutes, then repeat the test.

7. Checking the compatibility of cable and adapter

Even if your smartphone supports fast charging, it's limited to the weakest link in the circuit: adapter, cable, or port. Here's how to check each element:

Adapter (charger):

• 🔍 The original Xiaomi block should have a hologram with the brand logo.
• 📋 Power is indicated on the back (e.g. Output: 5V≈3A / 9V≈3A / 12V≈2.25A).
• ⚠️ Cheap adapters without certification often lie about power.

Cable:

• 🔌 Xiaomi’s original cables have thickened connectors and labeling 5A (fast-charging).
• 🚫 Cables from a set of budget models (for example, Redmi) 9A) only designed 2A and slow down charging.
• 🔄 For 67W+ You need a cable with support USB Power Delivery (usually bundled with flagships).

USB port:

• 🔌 USB-C — Supports fast charging (but not always).
• 🔄 Micro-USB is limited 18W (Even if the adapter is more powerful).
• 🛠️ If the port is contaminated or damaged, the charging speed drops. Clean it with a wooden toothpick (carefully!).

For maximum speed, use complete accessories. For example, charging Xiaomi 11T Pro adapter from Redmi Note 10 will go 2 times slower (33W instead of 67W).

💡

Fast charging only works if you meet three conditions: a support model of a smartphone + a powerful adapter + a quality cable. If even one element is "weak", the speed is limited to the slowest link.
