Xiaomi’s first charger: how to charge a new smartphone and not spoil the battery

You just unpacked Xiaomi's new smartphone -- whether it's Xiaomi's flagship 14 Ultra, the budget Redmi Note 13, or the foldable MIX Fold 3. The first thing you want to do is turn it on and start using it. But the natural question is, how do you charge Xiaomi for the first time so that the battery lasts as long as possible? There's a lot of conflicting information going on the Internet, from "discharge to 0%" to the myths of "three full calibration cycles." We'll figure out what's relevant for today's lithium-ion and lithium-polymer batteries, and what's the old-old batteries.

Xiaomi smartphones today are equipped with fast charging batteries and heat protection systems, but even these require proper handling from the first minutes of use. In this article, you will find not only step-by-step instructions for first charging, but also unique data on how MIUI algorithms control charging at the hardware level – information that is not disclosed even in official manuals. We will also analyze what the first charging is different for devices with HyperCharge (200W) and standard models with 33W.

Why First Charge Is Important: Myths and Reality

Many users believe that the battery’s fate will depend on the first charge for years to come, which is partly true, but not for the reasons that are written in the forums. It is not about “calibration” (a myth that is relevant for older types of batteries), but about the formation of a protective layer on the electrodes – the so-called “protein” of the battery. SEI-Solid Electrolyte Interphase, which is formed during the first charging-discharge cycles and affects the longevity of the battery.

However, modern Xiaomi batteries (such as those in the Xiaomi 13T Pro or POCO F5) are factory-run before they reach the user.

• ⚡ The battery already has. 30-50% The charge from the plant is not an accident, but part of the technological process.
• 🔋 First-time 2-3 charging cycles at the plant are held under controlled conditions (temperature, current).
• ⚠️ No need to specifically discharge the smartphone to 0% – it only increases wear and tear.

However, the first charge in the hands of the user still matters. Here the key factor is the temperature and charging current. For example, if you connect the Xiaomi 12S Ultra to 120W charging in a hot room, the battery can overheat, which will accelerate the degradation of the electrolyte. Xiaomi’s official recommendations (which are rarely translated into Russian) advise you to stick to a “sparing” mode when you first charge.

The algorithm for first charging depends on the smartphone model and battery type, and below is a general-purpose instruction that is suitable for most Xiaomi, Redmi and POCO 2020-2026 devices, except for devices with graphene batteries (such as some Black Shark models) – for which the rules are slightly different.

1. Unpack your smartphone and check the kit. Make sure the box contains the original cable (usually USB-C - USB-C or USB-C - USB-A) and a power supply (if it is provided for your model). For Xiaomi 14 Pro and the newer power supply may be missing - this is normal.
2. Connect your smartphone to charging. Use only original or certified cables. Charging from a laptop or a cheap power bank may not provide the right current.
3. If the smartphone is discharged before turning off, wait 5-10 minutes - the MI logo or charging indication should appear.
4. Charge to 100% without interruption. Do not turn off the power even if the smartphone is heated (but make sure the temperature does not exceed 40 ° C).
5. Turn off the charging and let the battery "rest." Wait 10 to 15 minutes, then turn on the smartphone and set it up.

Importantly, if you buy a Xiaomi smartphone with your hands or it has been in storage for more than 6 months, the first charge may take longer than usual, because lithium-ion batteries lose up to 5-10% of capacity in six months without use.

• 🔌 Charge the device with the original charger at reduced current (for example, use the power supply on the 18W instead 120W).
• ⏳ First charge time can increase to 3-4 hours.
• 📉 After full charging, run 1-2 discharge cycles to 20% and charge to 100% to “wake up” the battery.

Use the original cable and power supply

The temperature in the room is 10–30 °C

The smartphone does not lie under direct sunlight

Charging is connected to the socket, not to USB-hub

The screen displays a charging indication.-->

What not to do on the first charge

Some actions can not only shorten the life of the battery, but also disable it in the first days of use.

⚠️ Note: If you use a third-party charger with higher power 65W For models that do not support HyperCharge (e.g. Redmi) 10C), It can cause the power controller to fail, and at best, the smartphone will not charge, at worst, it will burn the board.

• 🔥 Charge your smartphone at a temperature below 0°C or higher than 45°C. Xiaomi Lithium-ion batteries have built-in overheating protection, but it doesn't work instantly.
• 🔌 Use wireless charging. Even if your model (like Xiaomi 13 Pro) supports Qi, the first charge must be through the cable.
• ⚡ Interrupt the charge by 80-90%. In the first cycles, it is better to bring the charge to 100% so that the battery controller correctly determines its real capacity.
• 📵 Enable energy-intensive tasks (games, video shooting) 4K). This puts additional stress on the battery and can lead to overheating.

The TurboCharge (33W), HyperCharge (120W/200W) and Surge Charging (for Black Shark gaming models) use high current, which accelerates battery wear when used improperly. If your smartphone supports ultrafast charging, when you first charge:

• ⏱️ Turn off the Ultrafast Charging function in the settings (Settings) → Battery → Charging).
• 🌡️ Watch the temperature of the case – if it becomes hot, turn off the charging for 10 minutes.

Optimal charging settings in MIUI for the new battery

MIUI firmware (including versions 14 and 14.5) contains hidden and explicit settings that help extend battery life.

For models with dual batteries (for example, Xiaomi 11T Pro or POCO F4 GT), the charge balance point may appear in the settings. It is better to leave it in Auto mode - the system will distribute the load between the two batteries.

If you want to maximize battery life, after the first 3-5 charging cycles, turn on Battery Savings mode (Settings → Battery → Battery Modes). This mode limits processor performance and screen brightness, but reduces battery heat and wear by 20-30%.

1. Discharge the smartphone before automatically turning off.

2 Charge to 100% without interruption.

3. Repeat the process 1-2 times.

This will help the controller to determine the level of charge more accurately.-->

What is different first charger for different models Xiaomi

Not all Xiaomi smartphones are the same — they have different battery types, power controllers, and support for charging technology. Below are key differences for the popular series.

Xiaomi 13/14 Series (including Pro/Ultra)

These flagships are equipped with silicone-carbide power controllers and support HyperCharge (120W) or Surge Charging (for gaming models).

• 🔌 Use only the original cable and power supply (complete or separately purchased by Xiaomi GaN Charger).
• ⏱️ Charging time to 100% is about 20 minutes, but for the first time it is better to stretch the process to 40-50 minutes by turning off HyperCharge.
• 🌡️ Watch the temperature: if the case is warm, turn off charging for 5-10 minutes.

Redmi Note 12/13 and POCO X5/F5

Budget and mid-budget models typically have 5,000mAh batteries with TurboCharge (33W–67W) support. The key here is not to use chargers that are more powerful than a smartphone supports. For example, if your Redmi Note 12 Pro+ is designed for 67W, don’t plug it into a 120W unit — it won’t speed up charging, but it can damage the controller.

Black Shark 5/6 Pro and other gaming smartphones

Xiaomi gaming devices often have dual batteries (two cells of 2500-2,750 mAh) and a liquid cooling system.

• 🎮 Do not run games or benchmarks (for example, 3DMark or Genshin Impact during charging.
• ❄️ Enable maximum cooling in the settings (Settings) → Productivity → Cooling).
• ⚡ Use only the original charger (usually) 120W).

Xiaomi Civi 3 and other compact models

Smartphones with a battery of < 4500 mAh (for example, Xiaomi Civi 3 at 4500 mAh) are more sensitive to overheating.

• 🌳 Charge in a ventilated room.
• 🔋 Do not use covers during charging (they worsen the heat sink).

💡

For models with HyperCharge support (120W/200W), the first charge should take place in a “sparing” mode - turn off ultra-fast charging in the settings and use a current not higher than 65W.

How to check if the first charge went right

After the first charge, it is important to make sure that the battery is working correctly. Here are 5 signs that everything is fine:

1. The smartphone is charged up to 100% in the stated time (for example, Xiaomi 14 Pro – ~20 minutes on 120W, Redmi Note 13 Pro – ~40 minutes on 67W).
2. The body temperature did not exceed 35-40 ° C (you can check in Settings → Battery → Battery condition).
3. There are no sudden jumps in charge level (e.g., from 100% to 80% in 5 minutes).
4. The smartphone does not turn off at 10-15% charge (a sign of correct calibration).
5. The Battery Status menu displays the status "Good".

If something goes wrong, here’s what to do:

• 🔄 Reset the battery settings: go to Settings → Annexes → Application management → Three dots (menu) → Reset the application settings. That resets the calibration data.
• 📊 Check battery wear: enter the dialer code ##4636##, select Battery Information and see Health Level (should be 100%).
• 🔧 Update the firmware: sometimes bugs MIUI affect power management. Check for updates in Settings → The phone. → Updating the system.

⚠️ Warning: If the smartphone runs too fast after the first charge (e.g., Xiaomi 13 Lite keeps the charge for less than 10 hours when used in moderation), this may indicate a battery defect or improper activation. In this case, contact the service center - under guarantee, the battery will be replaced for free.
