Buying a new gadget from Xiaomi is always accompanied by excitement, especially when it comes to the right start with the battery. Modern lithium-polymer batteries installed in the brand’s devices are radically different from the old nickel counterparts, which required a long “swing”. Many users still mistakenly believe that the new phone needs to be discharged to zero and charged to 100% several times in a row, but for current models of Redmi and POCO this action is not only useless, but can be harmful.
Engineers have implemented sophisticated power controllers that automatically optimize the energy storage process immediately after being removed from the box. If you just turned on the device, you don't have to search for special applications or perform complex manipulations. Just plug the original cable into a proven power source and wait for the process to be completed. The initial charging of a new Xiaomi device must take place with the screen off, but without the need for a full discharge to 0%.
In this article, we will take a look at the nuances of how your new purchase interacts with energy consumption. We will look at why old methods no longer work, how to configure the smart features of the MIUI or HyperOS shell to protect the battery, and what mistakes inexperienced users most often make. Understanding the physical processes inside the Li-Po battery will help you keep its capacity high for several years of operation.
Dispelling the myths about the first charge
There is a persistent stereotype that goes back to the early 2000s era of button phones, where there was a memory effect and the devices had to be trained. In the case of Xiaomi today, the battery is devoid of this effect and its chemical composition requires a completely different approach. Deep discharge below the critical voltage level can even damage the structure of the cells, reducing their real life.
The current energy management algorithms in the factory are doing the initial calibration, and when you pick up a sealed smartphone, the battery is usually about to charge. 50-60%. It's the optimal state for long-term storage in a warehouse. You don't have to aim to charge it immediately to the point where you can store it. 100% Or, conversely, completely plant. Lithium polymer cells are most comfortable in the range of 20% before 80%.
⚠️ Warning: Leaving a new phone discharged to zero for a long time (for example, for several weeks) is strongly discouraged.This can lead to a deep discharge, after which the device will refuse to turn on without special equipment.
Many users also believe that using non-original chargers will instantly kill the battery. While this is an exaggeration, Xiaomi's power controllers are indeed sensitive to current quality. Cheap power supplies without certification can give off unstable voltage, causing battery chemistry to heat and degrade faster than standard accessories.
First steps: What to do immediately after switching on
Once you have pressed the power button and have gone through the initial setup, the first thing to do is check the battery status. In the new Xiaomi 14, Redmi Note 13 or POCO F6 models, the interface may look different depending on the version of the shell.
If the charge is less than 20%, it is better to charge it immediately, without waiting for it to turn off. The process of initial system updates and application indexing can consume a significant resource, causing heating. The optimal temperature for charging is room temperature, so remove the protective case if it is dense and interferes with heat removal.
☑️ Initial battery preparation
It is important to use a complete cable and power supply, especially if your smartphone supports Xiaomi HyperCharge or SuperCharge fast charging technologies. Third-party cables may not support the necessary power transmission protocols, which will lead to slow charging with a conventional current of 5V/2A instead of the declared 67W or 120W.
Optimization in MIUI and HyperOS
Xiaomi’s shells provide powerful power management tools that often remain hidden by default. To activate them, you need to go to the settings menu. The path usually looks like: Settings → Battery → Battery Protection. Here are the key features that prolong the life of your device.
One of the most useful features is Optimized Night Charging, which is that the system learns your sleep habits, and if you put your phone on overnight charging, it will charge it to 80 percent, stop, and pick up the other 20 percent just before you wake up, which allows the battery to stay under high voltage for a long time, which is critical for lithium cells.
| Function | Where to find out. | Recommendation |
|---|---|---|
| Optimizing night charging | Settings → Battery | Include it. |
| Notice of 100% | Settings → Sound and vibration | If you wish, |
| Energy saving regime | Notification curtain | Only at low charge. |
| Limitation of background activity | Security → Battery | For rarely used applications |
You should also pay attention to the settings for specific applications. If you have installed heavy games or social networks, the system can limit their performance in the background. This not only saves charge, but also reduces heat. HyperOS does this more aggressively than older versions of MIUI, so periodically check the list of optimized applications.

Fast charging technologies: how not to harm
Xiaomi’s flagship and mid-range models feature ultrafast charging technologies ranging from 67W to 300W. This is convenient when you need to quickly restore power, but such currents inevitably lead to heating. Power controllers divide the battery into two cells, charging them in parallel, which reduces the load on each of them, but heat is still a side effect.
You don't have to use top speed mode all the time. If you're not in a hurry, you can use a regular 18-25 watt charge. It takes longer, but it will pass at lower temperatures, which will favorably affect the longevity of the chemical composition. Heating above 40 degrees is considered a stressor for the battery.
- 🔥 Avoid using your smartphone during fast charging, especially in heavy gaming, to avoid adding up the heat from the processor and battery.
- 🔌 Use certified cables with labeling 6A or higher to support high-power currents.
- ❄️ Remove thick silicone or leather cases during a fast charging session for better heat sink.
⚠️ Warning: If the phone gets hot to the touch while charging, interrupt the process or switch to a less powerful power supply. Prolonged overheating can cause the battery to bloat.
Operating rules for maximum service life
To make your new phone feel more autonomous in a year or two, you need to develop the right habits. The main rule is to avoid extremes. Don't let it run to 0% regularly and keep the device at 100% all the time. The middle ground is in the 20-80% range. Try to recharge the phone in small portions throughout the day.
Temperature is just as important as charge cycles: Don't leave your smartphone in direct sunlight, on the dashboard of your car in winter or summer. Low temperatures are also harmful: using your phone in extreme cold can lead to a sharp drop in voltage and emergency shutdown.
💡
If you plan to stay off the phone for a long time (e.g., leave the second unit), charge it to 50-60% and turn it off. Check the charge every 3-4 months and recharge it to this level to avoid a deep discharge.
Another important aspect is software. Regularly update the system. Xiaomi engineers often release patches that improve battery algorithms and fix bugs that cause elevated discharge in the background.
💡
The best strategy for a long battery life is to “partially” charge during the day and avoid extreme temperatures, rather than following strict rituals of total discharge.
