Buying a new smartphone is always an exciting moment, especially when you have a fresh flagship or a popular model from Xiaomi. After unpacking the device, the first natural desire of any user is to turn it on and quickly adjust. However, the screen often greets us with a badge of a dead battery or a request to connect a charger. It is at this point that most owners have a major question: how to perform the first charge, so as not to damage the battery and ensure its long service?
The lithium polymer batteries that are commonly used in modern Redmi, POCO and Black Shark gadgets are all surrounded by myths inherited from old technology. Many still believe that the new phone must be rocked, charging it for up to 12 hours or completely discharging it before it turns off. Current cell technology dictates completely different operating rules, ignoring which can lead to suboptimal operation of the power controller.
In this article, we will take a look at the algorithm for first turning on the device, explain the physics of the processes inside the Li-Po battery, and give you clear recommendations based on the manufacturer’s specifications. You will learn why factory charge can be low and whether you should panic if a new phone runs out of charge right in the box.
Should you completely discharge the new Xiaomi smartphone?
There is a persistent myth, coming from the era of nickel batteries, that a new battery must be discharged “to zero” before the device is spontaneously turned off. In the case of modern Xiaomi smartphones running on lithium polymer (Li-Po) or lithium-ion (Li-Ion) cells, this advice is not only useless, but potentially harmful.
Deep discharge below a certain voltage threshold causes stress to the chemical structure of the electrolyte. The power controller built into the battery pack specifically blocks the discharge before the critical state occurs to prevent degradation. So if your new phone is turned on and shows 40-50% charge, you don't have to aim to plant it to 0% for the sake of "calibration."
Moreover, long-term storage of a fully discharged device in a store warehouse or logistics center can lead to a voltage drop below a critical minimum, in which the controller can block the possibility of charging using standard methods, and the device will have to be “revived” with special equipment.
Why did the phone run out in the box?
Modern MIUI and HyperOS algorithms are already in the factory doing the initial calibration of the controller, and your job as a user is to just start using the device normally, avoiding extreme charge states in the early days.
Factory charge and preparation for the first inclusion
When you take the new Xiaomi out of the box, you're likely to find a low-charging battery icon on the screen, the optimal factory level is a range of 40 to 60 percent, and that's where the battery's chemical structure is most stable in long-term, non-use storage.
If the indicator is less than 20% or the phone does not respond to the power button, do not worry. This means that the device was on the road or on the shelf for a long time, in this situation, you need to plug in the original charger and leave the smartphone alone for 30-40 minutes, even if the screen does not light up immediately.
💡
Use only the original cable and power supply from the kit or certified accessories with support for Quick Charge, Power Delivery protocols to avoid overheating and unstable current supply.
The first turn on is better after the charge level reaches at least 20-30%, which will allow the system to complete the initial setup, update applications and index files without the risk of a sudden shutdown, which can disrupt the integrity of system files.
It’s important to understand that the initial setup process, which includes logging into a Google and Mi Account account, restoring backups and installing security updates, is extremely power-intensive, with the processor running at high frequencies and communication modules actively exchanging data.

The process of first charging a new device is not much different from the usual procedure, but following the sequence of actions will help to avoid errors and correctly calibrate the battery indicator.
- 🔌 Connect the cable to the power supply, and then insert the plug into the smartphone connector. It is important to follow this sequence to avoid a voltage surge.
- ⚡ Make sure the lightning icon or fast-charging animation appears on the screen.If the phone was completely discharged, the image can only appear through the 5-10 minute.
- 📱 Do not turn on the device immediately if the charge is less 10-15%. Allow the battery to gain a minimum amount of power for stable start-up of the system.
- 🌡️ While charging, make sure the smartphone is on a hard surface (table, nightstand) rather than on soft cloth or cushion to ensure heat is removed.
During intensive charging, especially using HyperCharge or Turbo Charging, heating is a normal physical process, but if the phone gets unpleasantly hot, it is better to remove the protective case or temporarily suspend charging.
☑️ Check before the first charge
After the indicator shows 100%, do not rush to pull the cord. Modern power controllers go into trickle-charge mode, compensating for the natural energy leak. Shutting down the device immediately after sunbathing the figure 100% can lead to the fact that in 10 minutes you will see again 98-99%.
How long to keep a new phone on charge
The question of the duration of the first charge is the most controversial. The old instructions advised keeping the phone on charge for 8-12 hours, but for Xiaomi with their advanced electronics, this rule does not apply.
The smartphone controls the process itself. When the battery reaches its physical maximum, the controller completely shuts down the current, and the device goes to power from the mains, bypassing the battery. It makes no sense to keep the phone on charging longer than necessary and does not increase capacity.
| Type of script | Recommended time | User action |
|---|---|---|
| Planned first charge | Up to 100% + 15-20 min | Wait for full filling and a small charge |
| Deep discharge (0%) | 30-40 minutes before switching on | Do not turn on until the screen signals a sufficient level. |
| Use of QC/PD technologies | Depends on the power (usually 1-1.5 hours) | Control the temperature of the body |
| Nighttime exercise | No restrictions. | The smartphone will turn off the current when it reaches the maximum |
It’s worth noting that the Optimized Charging system that is introduced in newer versions of MIUI can learn your habits. If you put your phone on overnight charging, the system can pause charging at 80% and hit the remaining 20% just before you wake up to minimize battery time at maximum voltage.
Battery calibration: does the new Xiaomi need it?
Many users immediately after purchase start looking for ways to calibrate the battery, fearing that the percentages on the screen will "lie."For a new Xiaomi device, forced calibration is usually not required.
Calibration is only necessary if you see obvious anomalies: the phone turns off at 15% charge, or after charging to 100%, it quickly drops to 90%. In such cases, you can conduct a calibration cycle manually, but you should only do this if there are problems.
⚠️ Attention! Do not cycle full discharge (up to 0%) and full charge (up to 100%) on a special and regular basis. This causes degradation of lithium cells. Calibration is an emergency measure to correct software errors, not a preventive procedure.
If you still decide to calibrate to eliminate display errors, do it once: discharge the phone before automatically turning off, then charge to 100% when off, then turn it on without turning off the cable, and make sure that the indicator shows full charge.
In most cases, it is enough to simply use a smartphone in normal mode. Artificial intelligence algorithms built into Snapdragon and Dimensity processors will independently adjust the display of capacity for 3-5 charge-discharge cycles.
Operating rules for extending the battery life
To make the new Xiaomi enjoy the autonomy not only in the first year, but also after 2-3 years of use, it is important to adhere to certain rules of operation.
The main enemy of the battery is extreme temperatures: overheating above +45 °C or cooling below 0 °C causes irreversible chemical damage. Try not to leave the phone in direct sunlight, on the car panel in summer or in the cold.
- 🔋 Avoid regular discharge to zero. Try to put your phone on charge when the energy level drops to zero. 15-20%.
- ☀️ Avoid overheating. Remove tight covers during games or fast charging if you feel a strong heating of the body.
- 🚫 Do not use damaged cables.The broken wire can cause voltage surges that are dangerous to the power controller.
- 📉 Don't keep your phone empty. If you put it in a long drawer, charge it to the front. 50-60%.
Also worth mentioning is the Overload Protection feature that is present in battery settings: Activating the charge limit option to 80% or 90% can significantly extend battery life if you use your phone in non-stop mode and rarely go without an outlet.
💡
The optimal charge range for daily use is between 20% and 80%, and this rule minimizes the wear and tear of the battery’s chemical structure.
