Xiaomi Redmi 8 Pro is a popular mid-range smartphone that is still widely used due to balanced performance and reliability. However, many owners have questions about the correct charging of the device: how much power is needed, can you use wireless charging, how to avoid rapid battery wear? In this article, we will examine all the technical details of charging Redmi 8 Pro, from official specs to practical tips for operation.
Now, let's just say, even though it was released in 2019, the battery system is still a topic for discussion, because the Redmi 8 Pro has a 4,500 mAh battery and it supports fast charging, but with limitations, and if you use the wrong adapter or cable, it can lead not only to slow charging, but also to premature battery failure.
Official Charging Characteristics of Redmi 8 Pro
According to the manufacturer’s specifications, Xiaomi Redmi 8 Pro is equipped with a charger with the following parameters:
- 🔌 Type of connector: USB Type-C (reversible, supports data transmission and power).
- ⚡ Adapter power: 18W (Quick Charge 3.0).
- 🔋 Battery capacity: 4500 mAh (lithium-polymer, non-removable).
- ⏱️ Full charge time: ~2 hours (using the original adapter).
It is important to understand that the Redmi 8 Pro does not support wireless charging (Qi) or ultrafast charging (Super Charge, HyperCharge).The maximum power that a smartphone can take is 18 watts. Using adapters with more power (for example, 30 watts or 67 watts) will not speed up charging, but will not harm the device due to the built-in protection system.
Compatibility with chargers: what can and what can not
One of the common questions is whether you can use chargers from other devices, and here are the key points:
| Adapter type | Power | Compatibility | Notes |
|---|---|---|---|
| Original (from the set) | 18 W. | ✅ Complete. | The best option for everyday use. |
| Adapter from Redmi Note 8 Pro | 18 W. | ✅ Complete. | It is similar to the original, can be used without restrictions. |
| Adapter from Xiaomi Mi 10 (30 W) | 30 Watts. | ⚠️ Partial | Charging will go to 18 watts, but the adapter will not damage the smartphone. |
| Wireless charging (Qi) | 5-10 W. | ❌ No. | The Redmi 8 Pro does not support induction charging. |
| Charging from a laptop (USB 2.0) | 2.5-to-5 W | ✅ Yeah, but slowly. | Suitable for emergency but not for regular use. |
The original Xiaomi cable is designed to run up to 3 A, which corresponds to 18 watts. Using cheap or damaged cables can lead to:
- 🐢 Significant increase in charging time (up to 4-5 hours).
- ⚡ Overheating of the connector USB-C adapter.
- 🔥 Risk of short circuit (in rare cases).
💡
If your Redmi 8 Pro is charging slower than usual, check the cable for damage. Often the problem is with the worn wire, not the adapter or smartphone.
How to charge the Redmi 8 Pro: tips for a long battery life
The Lithium Polymer batteries installed in the Redmi 8 Pro have a limited charging cycle life (typically 500-800 cycles).
Use an original or certified adapter|Avoid full discharge (charge at 15-20%)|Do not leave your smartphone on charge overnight|Store the device at a temperature of 10-35°C|Regularly update the firmware (in new versions) MIUI Optimized energy consumption)-->
One of the most pernicious myths is that a smartphone should be discharged to zero before charging; in fact, a deep discharge (below 5%) causes more damage to the battery than frequent recharging. The optimal charge range for extending its life is 20-80%.
Another important point is the temperature regime, and charging at extreme temperatures (below 0°C or above 40°C) can lead to:
- 📉 Rapidly reducing battery capacity.
- 💥 Battery bloating (in rare cases).
- ⚠️ Automatic Charging Disconnection (Integrated Protection).
⚠️ Note: If your Redmi 8 Pro gets hot during charging (over 45)°C, immediately disconnect it from the grid, this may indicate a malfunction of the battery or adapter, continued use in this condition is dangerous!
What to do if the Redmi 8 Pro is not charging
If the smartphone stopped charging, the reasons can be both software and hardware.
- Check the adapter and the cable. Connect another charger or check the current one on another smartphone. If the problem persists, the adapter or cable malfunctions.
- Clean the USB-C connector. A buildup of dust or debris may prevent contact. Carefully clean the connector with a toothpick (not a metal object!).
- Reset your smartphone. Sometimes the power failure is solved by simply restarting it. Press the power button for 10 seconds to force the device to shut down.
- Check the connector for physical damage, if the contacts are bent or oxidized, you'll need repairs at the service center.
- Reset the settings to factory. If the problem is software, reset can help. Pre-save the data! Path: Settings → About the phone → Reset.
What to do if the smartphone is charging, but very slowly?
If neither of these methods worked, it is likely that the problem lies in the malfunction of the power controller or the battery itself, in which case it is recommended to contact the Xiaomi service center or a proven wizard.
Can I use the power bank to charge the Redmi 8 Pro?
Yes, the Redmi 8 Pro is compatible with external power bank batteries, but there are a few nuances:
- 🔋 Power Bank: Optimal use of devices with Quick Charge 3.0 or Power Delivery support (PD). Minimum power: 10 W.
- 🔌 Type of connector: Make sure that the power bank has an outlet USB-C or USB-A 18-watt-enabled.
- 📱 Compatibility: Some cheap power bank may not recognize the Redmi 8 Pro and shut down.
Example of reliable power bank models for Redmi 8 Pro:
- 🔹 Xiaomi Mi Power Bank 3 Pro (20000 mAh, 45W).
- 🔹 Anker PowerCore 26800 (26800 mAh, 30W).
- 🔹 Baseus 65W Power Bank (20000 mAh), 65 W).
⚠️ Warning: Do not use a power bank with damaged connectors or a bloated battery. This could cause fire or damage to your smartphone. Always check the external battery for safety certificates (CE, RoHS).
How to check the status of the battery Redmi 8 Pro
Over time, the battery capacity decreases, which leads to a reduction in battery life. To assess the current state of the battery, follow the following steps:
- Use the built-in MIUI diagnostics: Go to Settings → About Phone → Battery Status. Here you can see approximate capacity and optimization recommendations.
- Install the AccuBattery app: This app analyzes charging cycles and shows the actual battery capacity. You can download it from Google Play.
- Check battery life: If the smartphone discharges in 4-5 hours with moderate use, this is a sign of strong battery wear.
Normal performance for the Redmi 8 Pro after 2 years of operation:
- 🔋 Battery capacity: 80-85% of the original.
- ⏱️ Battery life: 10-12 hours at average load.
- 📉 Standby discharge rate: 1-2% per hour.
💡
If the battery capacity has fallen below 70%, it is recommended to replace the battery in the service center. Further operation can lead to sudden shutdowns of the smartphone even at 30-40 percent charge.
