How to charge your phone without charging at home Xiaomi

When Xiaomi's smartphone is discharged at the wrong time and the original adapter is not available, many users are familiar with it. Often it happens that the cable is lost, the power supply is broken, or the outlet is too far from where you are. At such moments, panic arises, because communication with the outside world is interrupted and access to important applications is blocked. However, do not despair ahead of time, because modern technologies offer several workarounds to solve this problem.

In this article, we will discuss how to charge your phone without charging using improvised means and alternative energy sources. We will look at both the standard features of the MIUI operating system and the custom technical solutions available in the home. It is important to understand that not all methods are equally effective, and some of them require prior training or the presence of specific equipment.

Before you start to take action, you need to evaluate the battery status and the criticality of the situation. If the device shows 1-2% of the charge, the screen can go out at any time, so you need to act quickly and decisively. The fastest way to resuscitate the gadget is to use a USB port on your computer or TV, if they are in working condition. Let's look at the available options in more detail.

Use of the USB-port of household appliances and computers

The most affordable and common way to charge a Xiaomi smartphone is to connect to the USB-Computers, laptops, game consoles and even modern TVs are equipped with connectors capable of producing a current of 5 volts. Although the current strength in such ports is usually lower than that of the original power supply (often as low as 0.5A or 0.9A vs. 2A and higher), this is quite enough for a slow but stable charge.

When connecting to USB-The port of the computer needs to make sure that the computer itself is on or in a charging-enabled sleep mode. In some cases, if the computer is off but connected to the network, the port may continue to supply current, however, this depends on the motherboard settings. It is important for owners of Redmi and Poco to know that when connected to a weak source, a message about slow charging may appear on the screen - this is a normal reaction of the security system.

โš ๏ธ Note: It is not recommended to use old USB-hubs without their own power, as they may not provide enough current, and the phone will either not start charging, or will discharge even during connection.

If you use a laptop to charge your phone, keep an eye on the laptop's charge level to keep it from becoming critically depleted, and it's also worth noting that data transfer speeds can be limited when the port is used simultaneously for charging and synchronizing, and at home, it's one of the safest methods to use without needing to buy additional hardware.

Use of external batteries and Power Bank

The external battery, or Power Bank, is perhaps the most reliable solution to the problem of no outlet. It is a standalone device that allows you to charge your Xiaomi smartphone anywhere, whether it is a park, a transport or just another room where there is no access to the electricity grid.

To use the external battery efficiently, it is important to pay attention to its output characteristics. The device body always indicates the output parameters, for example, the output parameters, 5V/2A or 9V/2A. If your Xiaomi supports Quick Charge or Power Delivery fast charging technology, then using a compatible powerbank will allow you to recover energy much faster than through a conventional one. USB-port.

  • ๐Ÿ”‹ Make sure the Power Bank itself is precharged, otherwise it wonโ€™t be able to transfer power to the smartphone.
  • ๐Ÿ”Œ Use a high-quality cable that can pass the necessary current without significant losses.
  • โšก For models with fast charging, choose external batteries with support for appropriate protocols.

Many users forget that some Xiaomi models can work in reverse charge mode, but this is a feature of the phone itself, which we will talk about later. For now, let's focus on the fact that the external battery is a must-have accessory for every smartphone owner. It is compact, lightweight and always ready to come to the rescue in an emergency.

Wireless charging for compatible models

Xiaomiโ€™s flagship models, such as the Mi series and some of the top Xiaomis, are equipped with a wireless charging module. If you have one, the question of โ€œhow to charge your phone without chargingโ€ is solved simply by using a wireless charging panel. You will need the panel itself and a power supply for it, which can be borrowed from other equipment with similar characteristics.

The principle of operation is based on electromagnetic induction: the panel creates a magnetic field that is induced in the coil inside the smartphone, converted into an electric current. This is convenient, as it eliminates the constant connection and disconnection of the cable, reducing wear and tear of the physical USB Type-C or Micro-USB connector. Just put the phone on the surface of the charger, and the process will start automatically.

However, it's worth considering that wireless charging efficiency is lower than wired. Some of the energy is lost as heat, so the phone can get hotter than usual. Heating is a natural process when inductive charging, but if the device gets too hot, it's better to remove the case or process.

โš ๏ธ Attention: Metal plates in cases or magnetic holders may interfere with wireless charging and cause overheating.Remove the case before using the wireless panel.

If you don't have native wireless charging, you can buy a universal panel from third-party manufacturers, the main thing is that it supports the Qi standard used in most Xiaomi smartphones, which turns any surface with an outlet into a charging point, which is especially convenient in the bedroom or on the desktop.

Charging from another smartphone (Reverse Charging)

One of the most useful features in the MIUI ecosystem is the ability to recharge. Many modern Xiaomi and Redmi smartphones support OTG (On-The-Go) technology, which allows you to act as an external battery for other devices. If you have a second phone with a large supply of energy, you can pour some of the charge onto a discharged device.

To implement this method, you will need a USB Type-C cable on a USB Type-C or an OTG adapter. Connecting the two devices, you need to go to the battery settings and activate the โ€œReverse Chargingโ€ or โ€œReverse Chargingโ€ function. In some Xiaomi models, this menu is located on the Settings path โ†’ Additional functions โ†’ OTG, in others, the function is activated automatically when connected by cable.

The speed of such charging is usually slow, because it is limited by port capabilities and security algorithms, but it is a great way to reach the socket or make an important call.

How to turn back charging on different versions of MIUI?
On MIUI 12 and above: Settings -> Battery -> Access Point (or Charging section) -> Enable "Recharge." On older versions of MIUI: Settings -> Additional Features -> OTG -> Enable. If the menu is not available, search by settings by typing the word "OTG" or "Reverse".

Comparison of charging methods: speed and efficiency

So that you can choose the best way to do it, depending on your situation, we've developed a comparison table that will help you understand what to expect from each method and how long it can take to recover the charge. Different energy sources have different current strengths, which directly affects the speed of the process.

Charging methodAverage current strengthCharging speedEquipment required
Original charging2.0A - 6.0A+Very high.Native block and cable
USB port of the computer0.5A - 0.9ALow.PC/Laptop, cable

As you can see from the table, USB-The port of the computer is the most affordable, but the slowest way, and it's perfect for turning on your phone urgently to make a call or to view a card. If you need to quickly restore a significant percentage of the battery, it is better to use Power Bank or wireless charging, if the phone model allows it.

Cheap or damaged cables can significantly reduce the force of the passing current, turning fast charging into normal. Always use proven accessories, especially when it comes to charging from high-power sources.

Optimizing energy consumption during charging

When you charge your phone from a weak source, for example, USB-In the port of the TV, it is critical to minimize the energy consumption of the device itself, and in such conditions, the consumption can exceed the charge intake, and the battery will run out even with the cable connected.

The first thing to do is to turn on Airplane Mode, which will turn off all communication modules (Wi-Fi, Bluetooth, 4G/5G), which are the main consumers of energy in the background, and the screen should also be kept off or reduced to a minimum if the phone is needed.

  • ๐Ÿ“ฑ Close all applications running in the background, especially heavy games and navigators.
  • ๐Ÿ”‡ Turn off keyboard vibration and notifications so as not to waste motor power.
  • ๐ŸŒ‘ Use a dark theme if you have a screen. AMOLED, Black pixels do not consume energy.

Xiaomi owners can use the built-in optimizer. Press and hold the battery icon or go to the Safety app to activate the power saving mode. The system will automatically limit background activity and synchronization, which will help to quickly accumulate charge even from a weak source.

Tip: If the phone is low to zero and doesn't respond to the connection, leave it charging (even weak) for 15-20 minutes in the off state. Sometimes the battery takes time to gain the minimum voltage to start the system.

Frequently Asked Questions (FAQ)

Can you charge Xiaomi from a 220V outlet without a power supply?
No, you can't plug your phone directly into the socket. You need a converter (power supply) that will reduce the voltage from 220V to 5V. However, you can take the unit from any other equipment (router, old charging) with the same USB connector and characteristics.
Why does the phone charge so slowly from the computer?
Standard. USB-The computer ports (2.0) give a current of only 0.5A, and the ports 3.0 - about 0.9A. For comparison, conventional chargers give from 1A to 3A. In addition, part of the energy is spent on the operation of the phone system, if it is turned on.
Is it safe to use homemade charging devices?
Using homemade circuits (such as batteries) is highly discouraged without a deep knowledge of electronics. Unstable voltage can damage Xiaomi's power controller or cause battery fire.
What if your phone doesnโ€™t see USB charging?
Check the cable for damage. Try another one. USB-Clean the phone's charging connector of dust and pile (carefully, with a wooden toothpick).If nothing helps, the charge controller in the phone itself may be faulty.
