Let’s figure out how to charge the device efficiently and safely.

1.What is the right charger for RedmiBook 5?

Original power adapter that comes with RedmiBook 5, characteristic 100W (20V/5A) plug-in USB-C. It's the optimal solution, but what if the original is lost or malfunctioning? Can you use chargers from other devices?

RedmiBook 5 supports charging from any device USB-C adapter 65W and above, but there are important nuances here:

• 🔌 Power: Minimum recommended power — 65W. Charging on. 30W-45W (For example, from smartphones) will work, but the laptop will either not charge at full speed, or discharge faster than charging when loaded.
• 🔋 Fast Charging Protocol: The adapter must support PD (Power Delivery) 3.0 or higher without it, fast charging technology won't work.
• ⚡ Cable: Use only certified cables USB-C → USB-C High current support (preferably original or from proven brands like Anker or Baseus) cheap cables can overheat.

If you have lost the original adapter, the best alternatives are:

⚠️ Warning: Never use chargers with damaged cable or melted contacts, which can short-circuit and cause both the adapter and the laptop to fail. It is especially dangerous to connect RedmiBook 5 to cheap “wireless” charging via adapters – this violates the standard. USB-C PD may damage the port.

2.Optimum charging modes: how to extend the life of the battery

Lithium polymer batteries installed in RedmiBook 5, have a limited number of charging cycles (usually 500-800 But the right habits can extend this period by a considerable decrease in capacity. 20-30%. Here are the key recommendations:

• 🔄 Avoid full discharge: Optimal charge range — 20%-80%. Permanent grades up to 0% and charge up 100% accelerate the degradation of the battery.
• 🌡️ Control the temperature: The ideal temperature for charging — 10-35°C. When overheating (for example, during games), it is better to turn off the power and let the laptop cool down.
• ⚡ Use the "Sparing Mode": In MIUI RedmiBook has a charge limit of up to 80% (included in Settings) → Battery. This reduces the battery load.
• 🔌 Do not keep your laptop constantly on charge: If you work from the socket for a long time (for example, at home), periodically (once in a week). 1-2 Let's get the battery to last a week. 40-50%, Then charge back.

It's especially important to monitor the temperature in the summer if the laptop is heated above 40.°C during charging (can be checked in the HWMonitor program), follow the following steps:

Disable the charger and let the laptop cool down 15-20 minute|

Close resource-intensive programs (games, video editors)|

Lift your laptop to the stand for better ventilation|

Check the work of coolers in Settings → System system → Cooling-->

Many users are asking themselves, can you use your laptop while charging? Yes, but with reservations. If you do light tasks (documentation, video), it's safe. However, at high loads (rendering, games), it's best to charge the battery to 80% first, and then turn off the power to avoid overheating.

3. Fast charging: pros and cons

RedmiBook 5 Supports fast charging technology that allows you to restore to 50% capacity 30-40 It's convenient, but it has its own nuances:

• ⚡ Pros: Saving time - full charging takes about 1.5 hours 3-4. Comfortable on the road or in urgent need.
• ⚠️ Cons: Increases battery and adapter heating, can reduce battery life on a regular basis 10-15%.

How to use fast charging correctly?

1. Use it only when necessary (for example, before leaving the house).
2. Do not leave your laptop on fast charging overnight.
3. If the battery is already 80% charged, turn off fast charging and switch to normal mode.

Interesting fact: in RedmiBook 5 Implemented a smart charging control system, and if the laptop is connected to the network for a long time (for example, all working days), the system automatically limits the charge to the maximum of the charge. 95-98%, It's a little bit more powerful than the battery, but it only works with the original adapter.

Always, always.|

Only when you're in a hurry.|

There's no regular outlet nearby.|

Never use.|-->

4.Typical charging errors and their consequences

Even experienced users sometimes make mistakes that eventually lead to battery or charger problems, and the most common ones are:

• 🔌 Using uncertified chargers: Cheap adapters can not only slowly charge a laptop, but also damage the power controller.Symptoms: the laptop does not charge or is charged in jerks.
• 🔋 Storing a laptop discharged: If you leave RedmiBook 5 for long-term storage (e.g., for the 2-3 with a battery discharged, it may fail — 40-60%.
• 🌡️ Charging at extreme temperatures: Charging in the cold (below 0)°C) or in heat (above 40)°C) accelerates battery degradation, in the former case, irreversible cell damage may even occur.
• ⚡ Ignoring overheating signals: If the laptop is warming heavily during charging, and the coolers are working at their maximum - this is a sign that you need to turn off the power and let the device cool down.

One of the most insidious mistakes is using a laptop on a soft surface (like a sofa or blanket) that overlaps the vents, leading to:

• Overheating the battery and reducing its service life.
• Automatically disable charging (the laptop may show the message "Charging suspended: high temperature").
• Increased wear of coolers due to constant work at high speeds.

⚠️ Warning: If after connecting the charger, the laptop does not respond (the indicator does not burn, the battery does not charge), check the following: Connect the charging to another outlet - perhaps a problem on the network. USB-C (Reboot your laptop, sometimes the power controller fails by restarting. If nothing works, check the port. USB-C If the problem persists, the adapter or charging controller inside the laptop may have failed, in which case contact the service center.

5.How to check battery status and charging cycles

To understand the state of your RedmiBook 5 battery, you can use built-in tools or third-party utilities.

Method 1: Through MIUI (built-in settings)

1. Open the Settings. → Battery.
2. Click on the gear icon (⚙️) top-right.
3. Select the item "Battery status".
4. Here you will see: Current battery capacity (in mAh or %), Number of full charge cycles, Status score (Good, Medium, Bad).

Method 2: Through the Command Prompt (Windows)

If you have Windows installed, you can get more detailed information:

1. Open the command line on behalf of the administrator (Win) + X → Command line (administrator)).
2. Enter the command: powercfg /batteryreport /output "C:\battery_report.html"
3. Open the file. battery_report.html It's going to have detailed information about capacity, cycles, even battery life.

Method 3: Third-party utilities

For a deeper diagnosis, you can use programs:

• HWMonitor – shows voltage, temperature and current battery power.
• BatteryCare – tracks charging cycles and offers optimization.
• AIDA64 — Provides full battery information, including passport and current capacity.

Normal performance for RedmiBook 5 (after 1-2 years):

• Battery capacity: 85-95% primordial.
• Number of cycles: up to 300-400 (carefully used).

Charging from external sources: powerbank, car, solar panels

Sometimes you need to charge RedmiBook 5 in conditions where there is no outlet.

1. Charging from powerbank

To charge a laptop, you need powerbank with:

• Power from 65W.
• Support PD (Power Delivery).
• Capacity from 20000 mAh (or else enough for a day) 1-2 charge).

Recommended models:

• Xiaomi Mi Power Bank 3 Pro (100W, 20,000 mAh).
• Baseus 65W 20,000 mAh.
• Anker PowerCore 26800 PD.

Important: When charging from powerbank, a laptop can charge more slowly than from an outlet, especially if you are simultaneously using resource-intensive programs.

2 Charging in the car

This will require:

• Automotive Inverter (Converts) 12V into 220V) power-up 150W.
• Or adapter. 12V → USB-C PD (for example, ROAV 100W Car Charger).

Please note:

• Not all inverters are suitable for laptops – make sure the model supports a pure sine wave.
• Charging in the car may be less stable due to voltage fluctuations.

3. Solar panels

Theoretically, it is possible, but in practice it is:

• It requires a powerful panel (from the 100W) and the intermediary battery.
• It is very slow (depending on the lighting).
• Suitable only for emergency cases (for example, in a camping trip).

If you travel frequently, it is better to get a high-quality powerbank with support. PD — This is the most universal option.

💡

If you often work in places without outlets, set up in the Control Panel → Power: Maximum Autonomous Mode, which will reduce power consumption by limiting processor performance and screen brightness.

7. Software settings for optimizing charging

In addition to hardware, battery charging and consumption are affected by software settings. RedmiBook 5 has several useful features that will help extend the life of the battery:

1. Power modes in Windows

Go to Start. → Parameters → System system → Food and sleep mode and set up:

• When powered by battery: Set "charge savings" or "balanced" mode. Reduce the brightness of the screen to a comfortable level (optimally — 50-70%). Disable background applications (under "Privacy" section) → Background applications").
• When powered from the network: Select High Performance mode only when necessary (for example, for games or rendering). Turn on Optimize for Video if you watch movies - this will reduce the load on the processor.

2. Settings MIUI for RedmiBook

In the corporate shell MIUI There are additional options for laptops:

• Settings → Battery → Charging mode: "Sparing" - limits the charge to 80%. "Fast" - includes accelerated charging (not recommended for permanent use). "Balanced" - the best option for most users.
• Settings → Display. → Automatic Brightness: Turn on adaptive brightness so the screen doesn't shine at maximum without the need to.

3. Disconnecting unnecessary devices

Even if you don't use Bluetooth, Wi-Fi (when connected via cable), or keyboard lighting, they continue to consume power. Turn them off when they're not needed:

• Fn keyboard combination + F7 — Turning the aircraft on/off (disables all wireless modules).
• Fn + F9/F10 — keyboard lighting.

Another useful tip: if you leave your laptop without use for a long time (for example, at night), it is better to turn it off completely, rather than put it into sleep mode. 5 still spends about 5-10% charge-by-charge 8 hours.

💡

Setting up "Sparing mode" in MIUI and disabling background processes can increase the battery life on 15-25% without compromising productivity in everyday tasks.
