Myths about the first charge: what is true of this in 2026?

Let’s start by debunking a popular misconception that has been around for a decade now, many of which were relevant to nickel-metal hydride (Ni-MH) batteries, but are completely meaningless to today’s Li-Po batteries at Xiaomi.

🔋 Myth 1: “You need to completely discharge your smartphone before you first charge"

This is the most harmful thing you can do: Lithium-ion batteries have no memory effect, and a deep discharge (below 3%) leads to irreversible chemical changes. Xiaomi manufacturers even software block full discharge: the smartphone will turn off when the smartphone shuts down. ~5% charge to save the battery.

⚡ Myth 2: "First charge must be held. 8-12 hours"

This is a relic of the era of "stupid" chargers without controllers. Today's Xiaomi automatically turn off power when it reaches 100%, and then maintain the charge level with micropulses. You can't recharge — the maximum you get is heating the battery, which reduces its life.

📱 Myth 3: “You only need to use the original cable and power supply"

There is a grain of truth here, but it’s not so clear. Xiaomi does recommend original accessories for fast charging (for example, for the first time, 33W/67W/120W in flagships), but for the first charge, any certified cable with support will suit USB-PD Or Quick Charge. The key is to avoid cheap no-name adapters without protection from voltage surges.

🔄 Myth 4: "First-time 3 The charging cycle must be complete (0-100%)"

It’s half-truth. For calibrating the charge controller (not to be confused with “training” the battery!) it’s really helpful to charge your smartphone once before you can. 100% and let him discharge before 10-15% It's a mistake to do that every time you charge, optimal range for everyday use: 20-80%.

Why doesn’t Xiaomi write about it in the manual?
Manufacturers avoid giving specific charging recommendations to avoid being held responsible for possible user errors, and most buyers don’t read instructions deeper than the “How to Insert” section. SIM-Xiaomi’s internal documents for service centers contain completely different recommendations, for example, about the mandatory “run-in” of the battery in the first 7 days.

Xiaomi's Official Recommendations for First Charging (2026)

Unlike many brands, Xiaomi periodically updates its battery care manuals.The latest data for 2026 is based on research from the Xiaomi Power Lab and applies to all models Released after 2020 (including the Redmi Note 13, POCO F5, Xiaomi 14 and others.).

Here is what the manufacturer himself advises:

  • 🔌 Use original charging (or certified with Quick Charge support) 3.0+/USB-PD). For models with Turbo Charging (120W) This is critical – unoriginal adapters can burn the power controller.
  • 📊 First charge to 100% - but don't keep your smartphone charging after reaching maximum.Switch off power immediately after notifying you of a full charge.
  • 🔄 Avoid complete discharge in the first 7 Try to recharge the device when the charge drops to 15-20%.
  • 🌡️ Control the temperature if the body is heated above 35.°C (warm but not hot), remove the case and let the smartphone cool.
  • ⚡ Activate Adaptive Charging (if any in your model).This feature analyzes your habits and optimizes charging cycles. → Battery → Battery settings.

Pay special attention to models with dual batteries (for example, Xiaomi 13 Ultra or the other two). MIX Fold 3: Two cells run in parallel and the first charge must be done without the active use of the smartphone (do not run games or benchmark tests).

Unpack your smartphone and let it heat up to room temperature (if brought from the cold)

Connect the original cable to your native power adapter

Charge to 100% without interruptions (do not disconnect / connect the cable)

After 100% Let me stay on the charge again. 10-15 minutes (for balancing the cells)

Turn off the power and use the smartphone in normal mode before 15-20% charge

Repeat the charging cycle until 100% still 1-2 first-time 3 day-day-->

Now let's get to the practice. Below is a universal instruction, suitable for all modern smartphones Xiaomi, Redmi and other smartphones. POCO. If your model supports wireless charging (e.g. Xiaomi 14 Pro), the rules are the same, but use the original Qi 2.0 station or Mi Wireless Charging Pad.

📌 Step 1: Preparing your smartphone

Take your smartphone out of the box and let it acclimatize. 10-15 If you bring it from the street in cold weather (below) +5°C) Turn on the device and go through the initial setup without connecting to the charge. This is important that the system properly initializes the battery controller.

🔌 Step 2: Connecting to the charger

  • Use a complete cable and adapter. USB-C (Xiaomi after 2021, any high-quality cable with support will be suitable USB 2.0 or higher.
  • Connect the charging to a grounded outlet (especially important for fast charging) 67W/120W).
  • Don't use it. USB-Computer ports or power bank for the first charge – they may not provide enough current.

⚡ Step 3: The charging process

When you connect, you'll see a charging indicator on the screen. 10-15 The current may be increased (up to a minute) 3A In models with Turbo Charging, the system will automatically lower it to protect the battery. Do not interrupt the process, even if the smartphone is heated - this is normal for the first charge.

📊 Step 4: After reaching 100%

  • Turn off the cable from your smartphone immediately after notifying you of a full charge.
  • Let the device work. 5-10 minutes offline (you can turn on Wi-Fi and update applications).
  • Connect charging for another 10 minutes – this will help balance the cells (relevant to dual batteries).

🔄 Step 5: First cycle of discharge

Now use your smartphone in normal mode until the charge drops to 15-20%. Don't try to empty it to zero, it's bad for the battery. 100% still 1-2 once in the first three days, so that the controller accurately determines the capacity.

💡

If your Xiaomi supports reverse charging (e.g. Xiaomi) 13T Pro, do not use it in the first 7 days, this feature puts additional stress on the battery, which can affect its run-in".

What to do when you first charge (and why)

Some actions can not only shorten the life of the battery, but also damage the power controller or even cause the battery to bloat.

⚠️ WARNING: If you use a Xiaomi smartphone with fast charging support (30W+), Never connect it to charging immediately after heavy use (games, video shooting) 4K). Let the device cool until 30-35°C, otherwise you risk overheating the battery.

  • 🔥 Charge your smartphone under direct sunlight – the temperature is higher 40°C leads to degradation of the electrolyte and a decrease in the capacity of the 30-40% yearly.
  • ❄️ Charge below 0 temperature°C – Lithium-ion batteries lose their ability to take charge, and when frozen, the electrolyte can crystallize.
  • 🔌 Use damaged cable – bare wires can cause short circuit and damage the port USB-C.
  • 📵 Interrupt the charge on 80-90% first 3 cycle – this prevents the controller from accurately determining the actual battery capacity.
  • 🎮 Playing heavy games while charging - simultaneous high load on the CPU And the heat will lead to overheating and accelerated wear.

Especially careful should be the owners of smartphones with graphene batteries (for example, Xiaomi). 11T Pro) They can withstand higher currents but are sensitive to voltage drops. Always use the original adapter with Xiaomi HyperCharge support.

🌍 Global and Chinese versions

Please note that the Chinese versions of Xiaomi smartphones (for example, with the console) CN In models, there may be other charging protocols, such as the Xiaomi 13 Pro (CN) supportive 210W HyperCharge, while the global version is limited 120W. Always check the specifications for your area!

💡

For models with wireless charging (Xiaomi 14, 13 Pro, MIX 4) the first charge must be wired, this involves calibrating the controller, which first "learns" to work with the cable and then adapts to the Qi stations.

Frequent Questions and Problems During First Charge

Even if you follow all the rules, users are faced with unexpected situations, and let's look at the most common cases and their solutions.

❓ "Smartphone Charges Too Slowly When First Charging – This Is Normal?"

Yeah, first. 10-15 The system can limit the current to diagnose the battery if the speed has not increased through the 20 minutes, check it out:

  • Do you use the original cable and adapter?
  • Is the energy saving mode enabled (Settings) → Battery → Battery mode).
  • Does the smartphone overheat (if yes, remove the case).

⚡ "Can I use a power bank for the first charge?"

Most external batteries do not provide the stable voltage needed to calibrate the controller, except for Xiaomi's original Quick Charge power bank.

🔥 "Smartphone is very hot - what to do?"

Light heating (up to) 35-40°C. The first charge is normal, but if the body is hot (unpleasant to hold in your hand), follow these steps:

  2. Check if background processes are enabled (e.g. software updates).
  3. Charge the device in aircraft mode.
  4. If the heating is repeated, contact the service center (possible battery defect).

📉 "After the first charge, the battery discharges quickly - this is normal?"

First. 2-3 The autonomy of the day may be lower than the declared one - this is due to the background optimization of the system (MIUI Optimization. 3-5 Full charge-discharge cycles stabilize the operating time. If the problem persists, check the settings. → Battery → Using the battery for the presence of “gluttonous” applications.

Why Xiaomi does not recommend to discharge the smartphone to 0%?
Modern lithium-polymer batteries have protection from deep discharge, but each cycle is not enough. 0% It still causes microscopic damage to the anode, and Xiaomi says it's up to the point of being discharged. 0% At least once a month, the battery capacity is reduced. 2-3% The best minimum for a year — 10-15%.
🔋 Should you “rock” the battery of the new Xiaomi, as it was done before?
No, it's an outdated practice. Modern Xiaomi smartphones don't require battery training. 1-2 full charge-discharge cycles (up to) 15-20%) In the first days of use for calibration of the controller.
