Modern Xiaomi, Redmi and POCO smartphones come with activated lithium polymer batteries that have undergone initial factory calibration. Unlike older nickel batteries, the new Li-Ion and Li-Po cells do not require long “swings” for 10-12 hours immediately after being removed from the box.
Many users mistakenly believe that the first turn on should only occur after the device is completely discharged to zero and then many hours of charging, in fact, this procedure was relevant to the technologies of the past decade and may even harm modern electronics.
In this article, we will take a look at the algorithm for first turn on, explain why you shouldn’t wait for 100% charge to start working, and look at the MIUI or HyperOS settings that help keep the battery healthy.
Primary activation and charge level
When you first pick up a new smartphone, the battery is usually 50-60% charged, which is the optimal level for long-term storage of the device in stock before sale, as it minimizes the chemical degradation of the elements. Immediately after unpacking, you can safely turn the device on and start setting it up without connecting to the network.
If the indicator shows less than 15-20%, it is advisable to charge the device before reaching the 40-50% mark, which will allow you to comfortably go through the initial setup, app updates and synchronization of your Google account without the risk of a sudden shutdown.
⚠️ Warning: Don't attempt to artificially discharge a new phone before it's completely turned off (0%) before first charging.Deep discharge for modern power controllers is a stress factor.
The initial activation process is often high power consumption due to the high-frequency processor and the heavy use of communication modules, so if you plan to transfer a large amount of data from an old device or download voluminous games, it is better to keep the smartphone connected to the power source.
☑️ The first steps with the new Xiaomi
Destroying myths about the “rocking” of the battery
There is still a popular belief among users that several full charge and discharge cycles should be performed immediately after purchase, a myth that stretches back to the days of nickel-cadmium batteries, which had what is known as the “memory effect,” and modern lithium-ion batteries lack this drawback and do not require such rituals.
Moreover, the regular discharge of a modern smartphone to a state of complete shutdown is harmful to the chemical structure of electrolyte. The power controller in Xiaomi smartphones is designed to turn off the device even before the critical level of discharge, but to bring the gadget to this state should not be specifically designed.
Engineers recommend maintaining a charge range of 20% to 80% for everyday use, a “middle ground” where battery cell wear is minimal, and a full charge of up to 100% is required periodically only to calibrate the percentage of charge indicator, not as a daily routine.
- 📉 Myth: You need to fully discharge and charge a new phone 3 times.
- 📈 Fact: Lithium batteries have no memory effect and love partial cycles.
- 🔋 Reality: Deep scoring below 10-15% Accelerates battery chemistry aging.
- ⚡ True: Modern controllers control currents themselves, excluding overcharging.
Use of original accessories
The quality of the charger and cable directly affects the power recharge rate and temperature of the smartphone. Xiaomi smartphones often support fast charging technologies such as Quick Charge, Power Delivery or Xiaomi's proprietary HyperCharge protocols. Using non-original power supplies can cause the device to charge slowly or unstablely.
The original cable has the necessary cross-section of the wire to pass high currents (up to 6A and above in top models), cheap analogues often do not withstand such loads, which leads to their heating, voltage drop and, as a result, lower charging efficiency, in the worst case, it can damage the connection port.
When buying additional equipment, pay attention to certification. Cables should be able to transmit not only data, but also high currents. For wireless charging devices, it is also recommended to use certified stations to avoid overheating the back panel.
⚠️ Note: Use of damaged cables or power supplies of questionable quality may cause overheating of the device and damage to the power controller, which is not a warranty case.

Optimization in MIUI and HyperOS
The MIUI shell and the new HyperOS are equipped with advanced software tools to protect the battery. Immediately after purchase, it is recommended to go to the settings and activate functions that prolong the life of the battery.
In the battery settings menu, you can find "Optimize charging," which is trained in your usage habits and can pause charging at 80%, only to be completed by the time you wake up, which is especially useful for those who leave the phone to charge all night.
Also worth paying attention to the application autostart settings: Many programs try to constantly update in the background, which causes unnecessary heating and energy consumption. Restricting background activity for rarely used applications is an effective way to reduce battery load in the first months of use.
| Function | Where to find out. | Recommendation |
|---|---|---|
| Optimizing charging | Settings → Battery | Turn on for nighttime charging |
| Energy conservation | Settings → Battery | Use it at low charge |
| Auto-start | Settings → Applications | Disable for unnecessary apps |
| Temperature control | Systemically. | Monitoring the heating during games |
💡
Software optimization in MIUI/HyperOS can extend battery life by 10-15% due to smart charge current management.
Temperature and operating conditions
Temperature is the main enemy of any lithium battery. During the first charge and active use, the phone can heat up, which is normal for high-powered processors. However, it is critical to avoid overheating above 45 degrees Celsius, since high temperatures irreversibly reduce battery capacity.
It is not recommended to charge your smartphone under direct solar radiation or leave it on the dashboard of the car on a hot day, and it is also worth removing a tight protective case during intense charging or heavy games if you notice that the device body becomes hot to the touch.
Low temperatures are also harmful, though less so than high temperatures. Using a smartphone in the cold can cause a sharp drop in voltage and a sudden shutdown, although the physical charge in the battery still remains.
- 🌡️ Avoid charging on soft surfaces (sofa, bed) where ventilation is disturbed.
- ❄️ Do not use a cold phone immediately after entering from the street.
- 🔥 Remove the cover if you feel a strong heating of the back panel.
- 🌞 Do not leave the gadget under direct sunlight while charging.
💡
If the phone is very hot during charging, turn on the "Flight" mode for 5-10 minutes - this will turn off the radio modules and lower the temperature.
Frequent errors during first use
Many users make common mistakes that can reduce the life of a new device, one of the most common being using the phone while charging to run resource-intensive games or navigation, which creates a double load: the battery is charged and discharged simultaneously, causing a lot of heat.
Another mistake is ignoring system updates: the first firmware versions installed in the factory may contain bugs that affect power consumption. Manufacturers often release patches that optimize the power controller, so upgrading to the latest version of Android and shell is mandatory.
Also, don't panic if you notice that in the early days, the phone is running out faster than expected, indexing files, updating apps, and learning usage patterns, and typically after 3-5 days of operation, the battery is stabilized and reaches the manufacturer's stated level.
⚠️ Warning: Do not leave a fully discharged phone lying uncharged for a long time.Deep self-discharge can cause the voltage to drop below a critical level, after which a standard charger may not "rock" the battery.
