Xiaomi Redmi Note 8 Pro is one of the most popular mid-range smartphones released in 2019. Despite the fact that the model is long since retired, it is still actively used due to the balanced characteristics: powerful processor MediaTek Helio G90T, capacious battery 4500 mAh and support for fast charging.
In this article, we will look at what kind of charging comes with the Redmi Note 8 Pro, which adapters are suitable for the fastest possible charging, and give practical tips for extending the battery life.
Official Charging Characteristics of Redmi Note 8 Pro
Xiaomi Redmi Note 8 Pro supports Quick Charge 3.0 fast charging technology with a maximum power of 18 W. As standard, the device comes with an 18 W charging adapter (5V/3A, 9V/2A, 12V/1.5A), which provides battery charging up to 50% in about 30-40 minutes using the original USB Type-C cable.
It is important to understand that the actual charging speed depends not only on the power supply, but also on several factors:
- 🔌 Cable quality – Cheap uncertified wires can limit current.
- 🔋 Ambient temperature - in heat above 35°C charging automatically slows down.
- 📱 Background processes – active use of a smartphone while charging increases time.
- 🔄 Battery status – after 500 charging cycles, the battery capacity decreases by 15-20%.
Official Xiaomi tests show that a full charge from 0 to 100% takes about 1 hour and 40 minutes when using the original kit. ±15 minutes.
Compatibility with other chargers
One of the most common questions is: can I use charges from other devices for the Redmi Note 8 Pro? The answer is yes, but with reservations.
- ⚡ Quick Charge 3.0/2.0 — Best option for maximum speed.
- 🔌 USB Power Delivery (PD) — Compatible but limited to 18 watts.
- ⚠️ Standard charging. 5V/1A or 5V/2A — It will work very slowly (until then). 8–10 full-time).
Examples of compatible adapters:
| Adapter model | Max. Power. | Charging speed | Notes |
|---|---|---|---|
| Xiaomi 18W (MDY-08-EM) | 18 W. | ⚡ Fast (original) | It's complete. |
| Samsung 25W (EP-TA800) | 25 W. | ⚡ Fast (limited to 18 watts) | Supports QC 2.0 |
| Apple 20W (A2305) | 20 W. | ⚡ Fast (up to 18 W) | Requires a USB-C cable → USB-C |
| Standard. USB-port | 2.5-to-5 W | 🐢 Very slow. | Not recommended |
⚠️ Note: Use of chargers with more power 30 W (e.g. from Xiaomi) 33W/67W) It will not speed up charging – the smartphone is physically limited 18 Moreover, cheap high-power adapters can overheat and shorten battery life.
How to Choose a Cable for Quick Charging
Many people don't realize that cable plays a role that's as important as the adapter itself. The Redmi Note 8 Pro is a good fit for USB Type-C cables, but not all of them support high currents.
- 🔗 Certification – Look for the labeling USB-IF Or the words "Fast Charge".
- 📏 Length – cables longer than 1.5 m often lose power.
- 🛡️ Protection – quality cables have built-in resistors to prevent short circuits.
Recommended options:
- 🔌 Original Xiaomi cable (included) – the best choice.
- 🔌 Anker PowerLine+ — reinforced overflow, supports 18 watts.
- 🔌 Baseus Metal Series is a budget but reliable version.
⚠️ Caution: Cheap cables without certification can cause a Type-C connector to overheat on your smartphone. If the case near the charging port gets hot, turn off the cable immediately and replace it.

Myths about charging Redmi Note 8 Pro: what is true and what is not
There are many myths surrounding fast charging, and we'll take a look at the most common ones.
Myth 1: “Fast charging ruins the battery.”
✅ Modern Xiaomi smartphones use charging controllers that regulate current depending on temperature and charge level. However, the constant use of maximum power (18W) does accelerate battery degradation by 10-15% compared to standard charging (5W.
Myth 2: “You need to discharge your phone to 0% before charging.”
❌ The lithium polymer batteries used in the Redmi Note 8 Pro don't have a memory effect. The optimal charging range is 20-80%. Permanent discharges up to 0% reduce battery life.
Myth 3: “Trafficking at night hurts your phone.”
✅ True, but not critical. Modern smartphones automatically turn off power when they reach 100%, but prolonged charging at 100% (more than 4-5 hours) can speed up battery wear).
What is the “memory effect” and why is it not relevant for modern smartphones?
How to extend the life of the battery
The Redmi Note 8 Pro battery is designed for 500-800 charge cycles (depending on operating conditions).To maximize its capacity, follow these tips:
1. Avoid extreme temperatures.
- 🔥 Do not leave your phone in the sun or near heat sources (such as on a car torpedo in summer).
- ❄️ Do not charge your smartphone at a temperature below 0°C.
2. optimize the charging process.
- 🔋 Try to keep the charge level in the range of 30-80%.
- ⚡ Use fast charging only when you need to quickly restore the charge.
3. Set up your smartphone to save energy.
- 📵 Turn it off. 4G/5G Wi-Fi, if not used.
- 🔄 Reduce the screen refresh rate (if available).
- 🌙 Use a dark theme — AMOLED-The screen consumes less energy.
💡
If you leave your phone unused for a long time (for example, for 2-3 months), charge it up to 50% and turn it off. Storage at 0% or 100% can irrevocably damage the battery.
Frequent charging problems and their solutions
If your Redmi Note 8 Pro is slow to charge or not charging at all, the reasons may be:
1.The phone does not charge from the original adapter.
- 🔌 Check the cable for damage (bending, rupture of the overflow).
- 🧹 Clean up Type-C port of dust and debris with a wooden toothpick.
- 🔄 Try another socket or network filter.
2. Charging is going too slowly.
- ⚡ Make sure you use an 18W adapter (or higher).
- 📵 Close background apps, especially games and social media.
- 🔋 Check the temperature of the phone – if it’s hot, charging will automatically slow down.
3. the phone is charged only when it is off.
This may indicate:
- 🔋 Battery wear – replacement is required.
- 🔌 Problems with the power controller – repairs are needed.
- ⚡ Faulty adapter – try another power supply.
⚠️ Warning: If the problem remains after cleaning the port and changing the cable / adapter, do not use your smartphone while charging - this can lead to battery bloating.
💡
If the phone stopped charging after falling or getting moisture, self-repair can exacerbate the problem, and in such cases, professional diagnosis is required, since not only the charging socket, but also the power charge could be damaged.
