Buying a new Xiaomi gadget is always an exciting moment, accompanied by a desire to turn the device on faster and start using it. However, many users face a dilemma: should you discharge the phone to zero or immediately put on charge? Modern lithium polymer batteries, which are installed in the Redmi model, Poco and the flagship Mi, have their own characteristics of operation, different from old technologies.
Properly “first charging” the new Xiaomi doesn’t require complex rituals, but knowing the basic principles of how the battery works will help to extend its life. Unlike nickel batteries of the past, modern batteries do not have a “memory effect”, but are sensitive to overheating and extreme discharge states. In this article, we will discuss the real steps that need to be taken immediately after unpacking to make the device work as long as possible.
It's worth noting that the myth of 12-hour charging is a thing of the past, along with push-button phones. The power controller built into every modern smartphone controls the energy storage process by turning off the current when you reach 100%. Your task is to create optimal conditions for this process using original accessories and observing the temperature regime.
Status of battery in the box
When you first remove a smartphone from the box, the battery level is usually from the box. 40% before 60%. This is not a random or oversight of the manufacturer. Lithium polymer batteries are chemically unstable in a fully charged or fully discharged state during long-term storage. 50-60% It is optimal for the preservation of the container during logistics and storage.
If you find that a new phone is turning on but shows less than 10-15% charge, this may indicate a long lie in storage or self-discharge.In this case, you should not panic, but it is not recommended to immediately start heavy games or shoot video in 4K.
⚠️ Note: If the charging indicator does not light up immediately after connecting the cable, let the device lie on the charge. 10-15 Deep discharge sometimes takes time to "wake up" the controller.
It is important to understand the difference between the voltage the user sees and the actual chemical state of the battery. Calibration of the program metrics can take several cycles, but physical wear begins only from the moment of active use, so the initial charge is aimed more at stabilizing the system than at "training" the battery.
Why does the phone run out when it is turned off?
Choosing the Right Charger
With modern smartphones, Xiaomi often comes with a fast-charging adapter that supports Quick Charge technology or proprietary HyperCharge. Using a complete power supply is a guarantee that handshake protocols between the phone and the power supply will pass correctly. Third-party adapters may not support the declared power or, worse, supply unstable current.
If the original unit is missing or lost, choose certified counterparts from well-known brands such as Baseus, Anker or Ugreen. It is critical to pay attention to support for PD (Power Delivery) and QC 3.0/4.0. Cheap power supplies from markets often do not have adequate protection against voltage surges, which can damage the smartphone's power controller.
- 🔌 Use the original cable from the kit, as it is designed to transmit high-power currents (up to 6A in some models).
- 🔋 Check the labeling on the power supply: the output voltage must meet the requirements of your model (usually 5V/2A, 9V/2A higher).
- 🌡️ Avoid charging through USB-port of a computer or car for primary capacity set, as they often give out insufficient current.
The Mi Turbo Charge technology requires not only a powerful unit, but also a quality cable labeled 6A. If you use a third-party cable, the phone will automatically limit the charging current to standard values (usually 10-18 watts), which is safe, but will significantly increase the latency.
💡
For the fastest charging possible in the future, use automation scenarios that turn off Wi-Fi and Bluetooth when the phone is put on charge at night, which will reduce heating and background consumption.
The first charge process Step-by-step
The process of initial container setup is as simple as possible and without unnecessary actions. SIM-You've got a map and you've connected to Wi-Fi, just connect your smartphone to the network. MIUI HyperOS optimizes the background processes during charging to speed up the update and installation of applications.
☑️ Checklist of first charge
It is recommended to do the first full charge when the phone is turned off, or simply leaving it alone without actively using it, allowing the battery to warm up evenly and the system to determine the limits of capacity precisely. During charging, the phone can heat up — this is a normal reaction of lithium polymer cells to passing current, especially when using fast charging technologies.
Once the indicator shows 100%, don't be too quick to turn off the device. Modern algorithms use the "trickle charge" method to get the last percent and balance the cells. However, keeping the phone on charging for days also makes no sense: the power controller will block the current immediately after reaching full capacity.
| Type of charging | Speed (exemplary) | Impact on the battery | Recommendation |
|---|---|---|---|
| Original Fast (67W+) | 0-100% for 30-40 minutes | High heat. | Optimal for daytime use |
| Standard (10-18W) | 0-100% for 1.5-2 hours | Minimum heating | Perfect for nighttime exercise |
| USB port of PC (2.5W) | 0-100% for 4+ hours | Safe, but long. | Only in emergency cases. |
| Wireless (if any) | Depends on the base. | Average heating | Convenient but less effective |
Myths about the "rocking" of the battery
The topic of “how to charge the new Xiaomi” is still a subject of legends inherited from the era of nickel-cadmium batteries, the most common myth is that a new phone must be discharged to zero to turn off and then charged for 12 hours without interruption, a statement completely mistaken for modern gadgets.
Deep discharges below 5-10% are harmful to Li-Po and Li-Ion batteries. When voltage drops below a critical threshold, irreversible chemical processes begin inside the battery, degrading the structure of the cathode and anode. The smartphone controller is specifically programmed to turn off the device before physical zero occurs to keep the device rechargeable.
⚠️ Attention: Regular discharge of the smartphone until completely switched off (0%) Reduces battery life faster than daily charging 40-50%. Try to put your phone on charge when you have left. 15-20%.
It also doesn't make sense to keep your phone charging for hours after reaching 100%. Once the BMS (Battery Management System) signals a full charge, the current stops. Further sitting on the wire only keeps the level, using electricity from the grid and slightly heating the device, but does not add "capacity."
Optimization and settings MIUI / HyperOS
Xiaomi’s shells offer advanced power management tools that you can set up right after you first charge. You can find the “Optimize Night Charging” feature in the Settings → Battery menu, which will charge up to 80% when you activate your phone overnight, pause the process, and pick up the remaining 20% just before you wake up.
This approach minimizes the time the battery spends in a state of maximum voltage, which has a positive effect on battery chemistry in the long run, and it is worth checking the settings of the background activity of applications, as aggressive programs can prevent the phone from switching to energy saving mode.
To extend the life of lithium batteries, avoid overheating. If you notice that the phone warms heavily during charging, remove a dense case. Heat is the main enemy of lithium batteries, and high temperatures accelerate the degradation of the capacity faster than the number of charge-discharge cycles.
- 🛡️ Activate Battery Protection in the settings to limit maximum charge to 80% or 90% (available in newer versions of HyperOS).
- 📉 Disable unnecessary functions (NFC, GPS, Bluetooth) during charging, if not used to reduce heat.
- 🌙 Use Do Not Disturb mode at night so the screen doesn’t light up from notifications while charging.
Frequent questions and problems with charging
Users often experience a situation where the charging indicator flashes or the process is extremely slow. In most cases, this is due to the use of poor-quality cable or contamination of the USB Type-C connector. Simple cleaning of the port with compressed air or the careful use of a toothpick (no metal!) often solves the problem.
If the phone gets heated to a point where it's not pleasant to hold, the system can automatically limit the charging current or temporarily suspend it, which is a normal safety function, and then you should move the device to a cooler place, away from direct sunlight or heaters.
💡
The main rule of long life of Xiaomi battery is to avoid extremes. Do not discharge to zero and do not hold constantly to 100%.
In rare cases, after the first turn on, it may be necessary to calibrate the battery indicator if the percentages jump (for example, from 30% sharply falls to 5%).
