Buying a new gadget is always accompanied by a pleasant excitement and desire to start using it faster. However, after removing Xiaomi from the box, many users are faced with the dilemma: can you turn the device on immediately or should you first put it on charge?
Electronics manufacturers, including the Chinese brand Xiaomi, have long implemented advanced power controllers that automatically regulate the power supply. However, there are certain nuances that will help maintain maximum battery capacity for years to come.
In this article, we will take a closer look at what the correct first charge of Xiaomi’s smartphone looks like, whether to believe in the myths of 12-hour charging and how to set up the device for optimal power consumption. MIUI activate immediately after unpacking to extend the life of the battery.
Do I need to charge a new phone for 12 hours?
There is still a persistent myth among users, dating back to the push-button era, that a new battery must be charged continuously for 10 to 12 hours, a suggestion that was relevant to Ni-Cd (nickel-cadmium) and Ni-MH (nickel-metal hydride) batteries, which had what is known as the “memory effect.”
Modern Xiaomi smartphones are equipped with lithium polymer (Li-Po) or lithium-ion (Li-Ion) batteries, they have no memory effect, and the power controller built directly into the battery will not take more energy than the physical capacity allows. Recharge or “pump” such a battery simply impossible software.
⚠️ Warning: Leaving a new smartphone on charge all night or 12 hours in the hope of “rocking” the battery is a waste of time and electricity. Moreover, prolonged static load at 100% charge can slightly heat the device.
If you've just bought a Redmi or a Poco, you just need to get it to 100 percent in the normal way, and then you can turn off the cable and start setting up the system, and you don't need to do any special rituals with zero discharge and then extra-long charging.
Battery status at purchase and first start-up
Often, customers notice that a new phone just removed from the box already has a charge in the range of 40% to 60%.This is not a sign that the device has been used before you.
This level of charge (about half the capacity) is the most stable chemically, and it prevents the deep discharge that can occur if you leave a fully charged or fully discharged battery in storage for months. Deep discharge is detrimental to the chemistry of Li-Ion cells.
- 🔋 40-60% — Ideal level for battery preservation in stock.
- 📉 Less than 10% – may indicate long-term storage or self-discharge, requires immediate recharging.
- 📈 100% - undesirable for long-term downtime, as it accelerates the degradation of the electrolyte.
If you see a low percentage of charge when you turn on, just plug in the original adapter. Don't panic if the indicator doesn't light up right away: some models take a few minutes to wake up after a long storage period.

The process of first charging your new Xiaomi is as simple as possible and does not require complex manipulations, the main thing is to use high-quality components.Combined with most modern models (Mi series, Redmi Note) already comes the original power supply and cable that supports fast charging technology Quick Charge or Power Delivery.
Connect the cable to your smartphone first, and then plug the power supply into the socket, which helps to avoid a power surge when you connect, even though modern controllers are already protected from this, the device screen should catch fire, and the tray will appear a lightning icon.
☑️ Primary charging Xiaomi
While charging, the phone can heat up slightly - it's a normal physical process, especially when using HyperCharge's fast charging features. MIUI controllers will automatically lower the current if the temperature exceeds the permissible limits. Do not cover the phone with a cloth or cushion while charging to ensure heat sink.
After reaching 100%, it is recommended to wait another 10-15 minutes for the controller to balance the battery cells (if there are several), although in monolithic smartphones, this process is quick.
⚠️ Note: Using cheap Chinese power supplies without certification can damage your Xiaomi Power Controller.Always try to use the original adapter or certified analogues (e.g. Baseus, Ugreen with support for the right protocols).
Charging optimization settings in MIUI
The MIUI shell, which runs Xiaomi, Redmi and Poco smartphones, offers advanced tools to keep the battery healthy. Immediately after the first charge, it is recommended to go to the settings and activate the protection functions.
Go to Settings → Battery → Battery Protection. Here you will find the Optimized Charging switch.This feature uses artificial intelligence algorithms to analyze your habits. If you normally charge your phone at night, the system will charge it up to 80%, pause the process, and hit the remaining 20% just before you wake up.
It's also worth paying attention to charging notifications.The system can alert you if you leave your phone on charging too long after reaching 100%.This helps avoid battery stress caused by micro-charge cycles.
- 🛡️ Overheating protection – restricts current at high temperature.
- ⏰ Charging timer – allows you to set the time by which the phone should be charged.
- 📉 Limit of charge - in some versions MIUI You can limit the maximum charge to 80-90% prolongation.
Activating these settings on the first day of use is the best way to take care of the device’s durability, especially for gaming smartphones in the Black Shark series or Xiaomi 13/14 flagships that experience high loads.
Temperature and operating conditions
Temperature is the main problem with lithium batteries. On the first day of use, it is important to understand how your Xiaomi reacts to heat. The normal operating range is between +15 °C and +35 °C.
Charging at low temperatures (below 0°C) can cause permanent damage to the anode structure and a sharp drop in capacity. If you bring the phone in from the cold, let it warm to room temperature before connecting to the network.
| Conditions | Impact on the battery | Recommendation |
|---|---|---|
| Temperature below 0°C | Critical damage, risk of bloating | Do not charge, warm in the room |
| Temperatures above 45°C | Accelerated degradation, loss of capacity | Remove the cover, remove the sun. |
| Direct sunlight | Local overheating of elements | Charge in the shade or indoors |
| High humidity | The risk of contact oxidation | Avoid bathrooms at steam sources |
During the first charge, remove the dense silicone case, if any.Dense materials do not remove heat well, which can cause trottling (decreased performance) or slowing charging due to the thermal protection.
Myths about battery "training"
On the Internet, you can find advice about 3-5 full-discharge cycles (before shutdown) and full-charge cycles (up to 100%) to “calibrate” or “train” a new battery. For modern Xiaomi, this procedure is useless at best, and harmful at worst.
Deep discharge to the point where the phone itself shuts down is stressful to battery chemistry: The power controllers in Redmi and Poco are calibrated automatically in the background during normal use, and the system itself remembers the minimum and maximum charge points.
What is battery calibration really?
If you regularly discharge a new phone to zero for workouts, you'll only reduce the number of recharge cycles available. Lithium batteries like "surface" cycles: for example, discharge from 80% to 40% and charge back.
⚠️ Warning: Do not allow regular full discharge of the new smartphone at 0%.This can lead to a voltage drop below the critical level, after which the normal charging may not start, and you will need a “push” of current at the service center.
Operational rules for extension of service life
Once the first charge is complete and the phone is set up, you should stick to a few simple rules that will help your Xiaomi battery stay healthy for many years.
Try not to keep the charge at 100% or keep the charge below 15-20%, the ideal range for storing and running a lithium battery is 20% to 80%, and if you're at home by an outlet, it doesn't make sense to keep your phone connected all the time.
Use Battery Saving Mode → Energy Saving if you need to prolong your daytime work. Also turn off unnecessary features like GPS, Bluetooth, and NFC if you’re not using them right now, which will reduce heat and battery load.
- 🌡️ Avoid overheating – do not play heavy games while charging.
- 🔌 Quality cables – use wires with a bandwidth of at least 2And-3And.
- 📱 Original accessories – power supplies with a smart chip will charge your phone faster and safer.
Compliance with these guidelines will allow you to forget about buying an external battery or replacing the battery during the first 2-3 years of active use.
💡
If you use your smartphone to navigate in the car, plug it into charging, but turn on Do Not Disturb mode and reduce the brightness of the screen to minimize heat from the sun and the processor.
💡
Modern Xiaomi smartphones do not require complex battery preparation, the main thing is to avoid extreme temperatures and deep discharges.
