Buying a new smartphone is always an exciting moment, especially if you chose the popular Xiaomi Redmi. However, when unpacking the device, many users are faced with the first and most important question: should you charge the gadget right away or can you turn it on for initial setup?
Xiaomi smartphone owners are lucky as the company’s engineers are introducing advanced power controllers.However, the correct initial battery activation affects the accuracy of the display of percentage of charge and the long-term durability of the device. In this article, we will discuss how to conduct the first charge of your Redmi to avoid typical errors and keep the battery healthy for years.
It's worth noting that the myth of keeping your phone on charge for days is a thing of the past. Modern Li-Po batteries are much smarter and more sensitive to overheating than undercharging. So approaching the first switch on requires less time than understanding the processes that take place inside the device when the system starts.
Myths about the “swing” of the battery in Xiaomi smartphones
There are many legends surrounding the first Xiaomi Redmi charge that often confuse users. One of the most common ones is that the new phone must be discharged to zero and then charged to 100% when turned off several times in a row. This statement is wrong and can even be harmful to the lithium polymer cell.
The fact is that the power controller installed in the Redmi Note or Redmi Pro series is calibrated in the factory, deep discharge below a certain threshold causes stress in the chemical components of the battery, and in fact, modern MIUI systems automatically optimize energy consumption immediately after the first turn on.
⚠️ Warning: Never leave a fully discharged phone (when it is turned off) lying uncharged for weeks, which can cause the voltage to drop below a critical level, after which the regular charger may not wake the controller.
Another myth concerns the use of only original accessories. While Xiaomi recommends its cables and units, modern USB Power Delivery and Quick Charge standards allow you to safely use a certified third-party peripheral.
- 📉 Deep discharge is harmful to modern Li-Po batteries, unlike older Ni-MHs.
- 🔋 «The 12-hour swing is a relic of the past, relevant to phones in the early 2000s.
- 🛡️ The power controller in Redmi regulates currents by itself, eliminating the need for manual intervention.
- ⚡ Quick Charge is safe when first used if the power supply is of high quality.
Factory level of charge and its value
When you take the new Xiaomi Redmi out of the box, its battery is typically charged at 40 to 60 percent -- not by accident, not by builders -- but by the best way to store lithium cells in warehouses and logistics for long periods of time.
It is in the range of 50-60% that the chemical reactions within the battery are most slow, which minimizes the degradation of capacity during downtime. If you see 55% on the screen of a smartphone on, this is the perfect indicator of the correct storage of the device until the moment of sale.
💡
If your new phone is discharged completely (0%) right out of the box, it could indicate a long shelf life or a defect in the controller, in which case it is worth checking the production date on the box.
Many users mistakenly believe that if the phone is turned on, it should be urgently carried to the socket, in fact, the residual charge is enough to fully set up the initial setup, connect to Wi-Fi and install system updates, but if the indicator shows less than 20%, it is better to connect the cable before the action begins.
It's important to understand the difference between the actual charge and the system readings. When you first start up, MIUI can calibrate the percentage display, so don't be afraid if after an hour of use, the charge dropped from 60 percent to 45 percent, which is the system aligns the data from the sensors.
| Parameter | Norm for the new Redmi | An alarm signal. |
|---|---|---|
| Charge out of the box | 40% - 60% | Less than 10% or 100% |
| Charging temperature | Warm (30-35°C) | Hot (above 40°C) |
| Rate of dialing % | Uniform | Racing (10 percent, then 50 percent) |
| Simple behavior | Minimum expenditure | Fast discharge without action |
Step-by-step: the first charging Xiaomi Redmi
To ensure that your new gadget lasts, follow the correct activation algorithm. These are not complicated manipulations, but they will help the system correctly determine the capacity of the battery.
If the charge allows, go through the initial setting: select a language, connect to Wi-Fi and log in to the Mi Account. After that, it is recommended to install all available system updates through the Settings menu → About Phone → System Update. This will provide current drivers for the power controller.
☑️ Checklist of first activation
Now you can plug in the cable. Use the complete power supply and cable, because they're tailored to support Quick Charge or HyperCharge technology specifically for your model. Put the plug in the connector before you click and plug the plug into the socket.
When charging, the screen can go out and turn on, and the phone can get hot, which is a normal reaction to high incoming current. The system will reduce its charge rate when it reaches 80-90% so that it doesn't overheat the cells. Keep the device on charge until it reaches 100%.
- 🔌 Use only serviceable sockets and cables without visible damage to the insulation.
- 🌡️ Remove the protective case if it is dense and interferes with heat transfer during the first charge.
- 📱 Do not load the processor with heavy games at the time of initial charging.
- 🔋 After the 100% You can still hold your phone on charge. 15-20 cell-balancing.
Optimizing MIUI to extend battery life
The MIUI shell offers powerful power management tools that you should set up immediately after you buy. Go to the Security → Battery app, and you'll see the flow chart and the ability to switch modes here.
For everyday use, it's recommended to turn on Charging Optimization, a feature that learns your habits: if you put your phone on overnight charging, the system will charge it to 80% and stop, taking the rest just before you wake up, which significantly reduces the wear and tear of the lithium battery.
Hidden battery settings
Also worth paying attention to the background activity of applications. In the Settings menu → Battery and performance → Energy saving applications can limit the operation of programs that you rarely use, this will prevent them from imperceptible discharge in the background.
Remember, temperature is critical for battery chemistry. Try not to leave a charging Redmi under direct sunlight or on a cushion where air circulation is disrupted. Overheating is the main enemy of any electronics.
⚠️ Warning: If the phone gets too hot during charging (uncomfortable to hold in your hand), immediately disconnect it from the mains.This may indicate a fault in the cable, power supply or battery itself.
Using fast charging: harm or benefit?
Modern Xiaomi Redmi models often support fast charging technologies ranging from 18W to 120W and up. Many fear that high speed degrades the battery faster. In fact, the speed here is secondary, the main thing is heat.
Quick Charge 4+ and HyperCharge are smart: they only deliver maximum current when the battery is severely discharged (e.g., up to 50%). The current is then smoothly reduced. So using a native fast unit is completely safe for a new device.
Problems can only arise with cheap analogues that claim high power but lack proper protection and protocols for matching the phone, in which case Redmi can charge slowly or intermittently in an attempt to protect itself.
💡
Fast charging is safe if you use original or certified equipment, and the main enemy of the battery is not speed, but overheating.
If you plan to use your phone in navigation mode or play while charging, fast charging may not be able to keep up with your energy consumption, and the percentage will stand still or even decrease.
Table of typical errors at the first use
To organize information, let’s look at the most common mistakes that users make when they first get to know Xiaomi, and avoiding them will save battery life as much as possible.
| Mistake. | Consequence | Right action. |
|---|---|---|
| Charge up to 100% in the off state | Waste of time, stress of the controller | Charge in the on state |
| Using a PC for a first charge | Slow charging, risk of voltage surges | Use the 220V network outlet |
| Playing while charging | Overheating, deformation of the body, bloating | Let the phone lie down. |
| Total zero-point. | Deep discharge, loss of capacity | Bet on charging at 15-20% |
Remember, the power controller is a complex microcomputer, it remembers charge-discharge cycles, and if you keep your phone on a regular basis, it will become accustomed to extreme modes, which will reduce your total battery life.
Compliance with simple rules of operation in the early days of using Redmi lays the foundation for stable operation for years to come.
