Xiaomi’s current smartphones are now available with a battery cycle already activated in the factory, which means you can start using the device immediately after unpacking without having to resort to the elaborate battery-swinging rituals that were relevant to nickel batteries a decade ago. However, getting the right initial charge is important in the long run, as it helps the power controller calibrate capacity correctly.
New gadget owners often face conflicting information about how to handle the device in the first 24 hours: Should you completely discharge your phone before you turn it off? Should you keep it on charge all night? Let's take a look at the technical details of lithium polymer batteries to extend the life of your device.
The main purpose of this instruction is to explain the physics of the process and give clear recommendations for the operation of the device during its run-in period. The correct approach to the first charge cycle will allow the system to accurately display percentages and avoid sudden shutdowns in the future.
Myths about “swinging” and the reality of Li-Pol batteries
There is a persistent misconception, which came from the age of old mobile phones, that a new battery must be discharged to zero and charged to 100% several times in a row. For today’s Li-Pol and Li-Ion batteries used in all current Xiaomi models, deep discharge is more stress than a useful procedure.
The manufacturers of the batteries indicate that such batteries do not have a “memory effect” that would require a complete discharge to restore the capacity.In contrast, a voltage drop below a critical threshold can trigger chemical processes of electrolyte degradation.
⚠️ A deep discharge of up to 0% when the new Xiaomi smartphone is first turned on does not give an increase in capacity, but only creates an unnecessary load on the chemical structure of the battery.
However, the calibration procedure for the battery meter software is necessary: the MIUI or HyperOS operating system must correctly count the remaining operating time and percentage of charge, and for this it is recommended to perform one full cycle from the moment of on-line to 100% at the very beginning of use, but without fanaticism and repeated repetitions.
Selection of charger and cable
The modern Xiaomi smartphone kit often includes an original power adapter that supports fast charging technologies such as Quick Charge, Power Delivery or proprietary Xiaomi Turbo Charge. Using a regular power supply ensures that the power controllers inside the phone and charger “agree” on the supply of optimal current.
If you plan to use a third-party charger, make sure it meets the necessary safety standards. Cheap, uncertified counterparts can give off unstable voltage, which will overheat and accelerate wear of the BMS (Battery Management System). Cable also plays an important role: fast charging requires wires with increased cross-section of the veins.
- 🔌 Use the original adapter from the kit to activate maximum charging speeds.
- 🔌 Check the cable for clogs and insulation damage before connecting.
- 🔌 Avoid cheap power supply analogues from markets without safety labeling.
When connected to a computer or universal USB-The charging speed will be much lower, since the current is limited by the standard. USB (This is safe, but ineffective for initial saturation of a large-capacity battery.
Step-by-step instructions for the first charge
The process of first charging the new Xiaomi device is simple, but requires a sequence of actions to ensure the correct operation of the controller. First connect the cable to the phone turned off or on (the difference for modern controllers is almost no, but the classic method involves connecting the device turned off), and then turn the power supply into the socket.
When charging, the phone can get a lot of heat, especially if you're on fast charging, which is a normal physical reaction of the chemical elements to the flow of high-power current, but if the device gets so hot that it's uncomfortable to hold in your hand, it's best to remove the protective case to improve heat sink.
⚠️ Warning: Do not cover a charging phone with a pillow or blanket – overheating is the main enemy of lithium batteries and can reduce their lifespan.
Keep the device on charge until the indicator on the screen does not show 100%, and another 15-20 minutes after that to complete the saturation stage (top-off).

Battery calibration and software configuration
Once the phone is charged and turned on, the system begins active background indexing of files, installing updates and synchronizing accounts. In the first hours of operation, the energy consumption can be higher than usual. To calibrate the battery successfully, the system needs to "see" the full cycle of operation.
Some users prefer to use special commands or apps to reset battery statistics, but newer versions of Android and Xiaomi shells do this automatically. Just use the phone as normal. If you notice that the phone turns off at 10-15% or jumps percentage of charge, you can perform manual calibration.
For manual calibration, discharge the phone until it turns off automatically (but don't store it in that state), then charge it off to 100%. Repeat the cycle of use after switching on. Usually one or two cycles are enough for the power controller to level the readings.
Do I need to install applications to save energy?
Optimizing MIUI and HyperOS settings for energy conservation
Immediately after the first turn on, it is recommended to go to the settings and adapt the system to your needs. The screen is the main consumer of energy, so adjusting the refresh rate and brightness will give a tangible result. AMOLED-It is also important to set up a dark theme.
Go to Settings → Battery. You can activate the power saving mode if you plan to run long hours without recharging, you should also check the list of applications that allow auto-start and background activity, disabling unnecessary processes will prolong battery life.
| Setup parameter | Recommended value | Impact on the battery |
|---|---|---|
| Screen refresh rate | 60 Hz or Auto | High (reducing to 60 Hz saves up to 15%) |
| Dark subject matter | Included. | Medium (critical for AMOLED screens) |
| Interface animations | Standard or 0.5x | Low (affects speed, but not capacity) |
| 5G modem | Turned off (if not necessary) | Very high (a 5G search will quickly drain the battery) |
Special attention should be paid to the function of "Advanced memory", which, although it speeds up multitasking, constantly writing and reading data from virtual memory can increase the power consumption of the processor. If you do not play heavy games, this feature can be left in the standard state.
💡
For maximum nighttime charge savings, turn on Sleep Mode in the Battery section – it limits background activity and notifications from 23:00 to 07:00.
Frequent errors in the operation of a new smartphone
Many users make mistakes that negate all efforts to properly charge their first charge, one of the most common being using a phone while charging to run resource-intensive games or video shooting, which causes simultaneous heat from the processor and battery charge, which is critically harmful to battery chemistry.
Another mistake is to use wireless charging as the primary method of charging all the time, and while convenient, the wireless method is less efficient and generates more heat due to losses in inductive power transmission, and for daily use, it is better to alternate methods or use a wired connection.
- 📱 Do not play heavy games during fast charging to avoid overheating.
- 📱 Do not leave your phone charging in direct sunlight or near the heating battery.
- 📱 Avoid using your phone in temperatures below -10°C or higher +45°C.
Remember, the ideal charge range for long-term lithium battery storage is 40-60%. If you put your phone in the closet for a long time, don't leave it fully charged or completely discharged.
💡
The main secret of longevity battery is to avoid extreme conditions: do not keep your phone 100% constantly and do not allow a deep discharge to zero.
