What type of charging Xiaomi Redmi Note 8: connector, power and compatible adapters

Why it’s important to know the type of charger your Redmi Note 8

The Xiaomi Redmi Note 8, launched in 2019, is still a popular choice among users due to its balanced specs and affordable price. However, over time, many owners have faced the question: what type of charging supports this device, and can modern fast chargers be used? The answer to this question is important not only for battery safety, but also for optimizing charging time.

In this article, we will discuss in detail the type of connector, supported charging protocols, as well as the compatibility of the Redmi Note 8 with various power supplies – from standard to powerful adapters with Quick Charge technology. You will learn how to choose the right charger to avoid damaging the battery and quickly restore the charge of the smartphone.

We will pay special attention to common myths – for example, whether it is possible to use charging from the Redmi Note 9 or POCO X3 for this model, and what happens if you connect the device to an adapter with a power of 33W or 67W. Also consider the current problems that users face when charging, and give practical recommendations for solving them.

Technical Charging Specifications of Xiaomi Redmi Note 8: connector and base power

The Redmi Note 8 is equipped with a standard USB Type-C connector (version 2.0), which means that the device supports reversible cable connection, but does not have high-speed data transfer on the USB 3.x standard - only charging and transferring files at speeds up to 480 Mbps.

The basic configuration of the smartphone included a charger with the following parameters:

  • πŸ”Œ Type of connector: USB Type-C (mother) β†’ USB Type-A (Daddy)
  • ⚑ Power: 10W (5V/2A)
  • πŸ“¦ Protocol: Standard charging without fast technology

It is important to note that the Redmi Note 8 does not support Qualcomm’s proprietary Quick Charge technology, despite the presence of a Snapdragon 665 processor, which is theoretically compatible with the QC 3.0. The manufacturer has limited hardware support, so even when connecting an adapter with Quick Charge, the smartphone will charge at standard power.

⚠️ Note: Using low-quality cables with Type-C connector may cause contacts to overheat or charge unstable. Always check the cable certification (e.g., labeling). USB-IF).

Supported Charging Protocols: What Really Works

Despite the lack of official Quick Charge support, the Redmi Note 8 is capable of running some alternative fast-charging protocols.

Standard charging (5V/2A)10Wβœ… Complete.Basic mode, safe for the battery
Quick Charge 2.0/3.018W❌ No.Smartphone ignores protocol, charging goes to 10W

MediaTek Pump Express15W❌ No.Not supported by hardware
Xiaomi's proprietary protocol18Wβœ… Yes.Only with original Xiaomi adapters (e.g. from Redmi Note 7/9)

Interesting fact: when using the original charger from Xiaomi Mi 9 (power 18W), the Redmi Note 8 can charge at ~15W, which is 30-40% faster than the standard 10W. This is due to internal firmware optimization for adapters of the same manufacturer.

Can I use charging from other Xiaomi smartphones?

Many users are wondering whether the charger from the Redmi Note 9, POCO X3 or Mi 11 for the Redmi Note 8 will work well?

  • πŸ”‹ Redmi Note 7/9 (18W): Compatible, but the actual power is ~12-15W.
  • ⚑ POCO X3 (33W): Smartphone will limit the power to 10-12W, There's no quick charging.
  • πŸ“± Mi 10/11 (30W+): possible problems with the recognition of the protocol, charging can go jerky.
  • πŸ”Œ Old models (Redmi) 5/6, 5W): Safely but very slowly (5W).

The rule of thumb is that the charging power is always limited to a smartphone, not an adapter, so even if you plug the Redmi Note 8 into 67W or 120W blocks, it won’t burn, but it won’t charge faster.

⚠️ Note: Use of adapters with higher power 30W (For example, from laptops) can cause Type-C cables to overheat. 5A (marking USB-IF 5A).

Is the original Xiaomi cable used?

Does the adapter have a power of less than 30W?

Is the adapter labeled Quick Charge or Power Delivery?

Does the charge not heat up more than 40Β°C?

Problems with charging Redmi Note 8: causes and solutions

If your Redmi Note 8 has stopped charging or is doing so too slowly, the reasons may be:

  1. Type-C connector contamination. Dust and debris accumulate in the port, disrupting contact. Solution: gently clean the connector with a wooden toothpick (not metal!).
  2. Wearing cables. Wrapped spans or damaged contacts inside the connector cause intermittent charging. Check the cable for clamps.
  3. Firmware failure. Sometimes, after updating MIUI, the smartphone misidentifies the type of charger. Solution: reset to factory settings (Settings β†’ About Phone β†’ Reset).
  4. Battery bloating. If the smartphone case is swelling and the battery is running out quickly, it needs to be replaced. It's dangerous to use a device with a bloated battery.

To diagnose the problem, go to the engineering menu of the smartphone:

##4636##

Select Battery Information. If the charging status says Unknown or Not charging, the problem is most likely a cable or adapter.

How to check the actual charging power?
1. Install the AccuBattery app from Google Play. 2. Connect the charger. 3. Open the Charging tab - the app will show the current power in mW. 4. Compare to the declared characteristics of the adapter. If the difference is greater than 20%, the cable or power supply is faulty.

How to speed up the charging of Redmi Note 8: practical tips

While the Redmi Note 8 doesn’t support ultra-fast charging, there are a few ways to reduce battery recovery time:

  • ⚑ Use the original Xiaomi adapter on the 18W. Even if the smartphone does not support Quick Charge, branded power supplies give an increase to 15W.
  • πŸ“΅ Shut down the network. 4G/LTE When you charge, the modem uses a lot of power, go into mode. 2G Or turn on Flight Mode.
  • πŸ”„ Close the background apps, especially those that are actively used. GPS Internet (for example, navigators, messengers).
  • 🌑️ Avoid overheating.Do not charge your smartphone in direct sunlight or near heat sources: 10-30Β°C.

It is also worth considering that after 80% When you charge, the battery recovery rate automatically decreases, which is embedded in the firmware to extend the battery life. If you need to quickly refuel your smartphone, disconnect it from the network when you reach the battery. 80-85%.
