How to Charge Xiaomi’s New Smartphone for the First Time: The Complete Guide to 2026

Why Xiaomi’s first charge raises so many questions – we’re dealing with myths and facts

You've 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 -- and the eternal question is how to charge it for the first time? There are dozens of controversial tips online, from "discharge to 0%" to "keep on charging for 12 hours." Most of them are remnants of the nickel-cadmium battery that have long given way to lithium polymer batteries in today's smartphones.

Xiaomi doesn’t officially publish specific instructions for first charging because modern batteries don’t require “training” or “calibration” when first used. However, there are nuances that can help you activate the power controller as efficiently as possible and extend battery life by 10-15%. In this article, we’ll look at what’s really important and what’s useless rituals.

Myths about the first charge Xiaomi: what is true and what is fiction

Let’s take a look at the most common misconceptions that are circulating on forums and social networks:

• 🔋 Myth 1: “You have to completely discharge your phone before charging the first charge.” Reality: Lithium Polymer batteries (Li-Po) used by Xiaomi do not have a memory effect. Deep discharge (below 3%) is even harmful to them.
• ⚡ Myth 2: "First exercise needs to be done. 8-12 Reality: Modern smartphones automatically turn off power when they reach 100%. Overcharging is impossible thanks to the built-in controller.
• 📉 Myth 3: "If you don't do the first charge correctly, the battery will run out quickly." Reality: The capacity of the battery is determined by chemical processes, not the first charge cycle.
• 🔌 Myth 4: "You can only use the original adapter." Reality: It's important to follow the power (W) and charging protocol (Quick Charge, Turbo Charge.

So why are these myths so tenacious? 10-15 Batteries did require running-in years ago, but technology has moved forward, and advice has remained. Today, the only thing that really matters is avoiding extreme battery states (too high or too low charge) and using quality chargers.

Xiaomi’s official position: what the manufacturer says

The manuals of Xiaomi, Redmi and POCO do not have a separate section on first charging, but some models (such as the Xiaomi 13T Pro or Redmi K60) have general battery life guidelines:

⚠️ Note: Using uncertified chargers can cause battery damage or even fire.Always check if the adapter power meets your model's requirements.

The responses of the support service Xiaomi Russia specified:

• 📱 For the first charge, just connect the phone to the original adapter and wait for 100%.
• ⚡ You don’t have to keep charging longer than it takes to reach 100%.
• 🔄 Avoiding full discharge (below 5%) and constantly charging up to 100% in everyday use.

Interestingly, in some regions (e.g. China), Xiaomi is shipping smartphones with a partially charged battery (about 40-60%), which is done to comply with the rules for transporting lithium-ion batteries and at the same time for optimal storage. If your Xiaomi came with a charge of 0%, this can mean long-term storage in stock.

Step-by-step: how to charge Xiaomi for the first time

Now, let's get to the point. Here's the optimal first-charging algorithm that will help you initialize the power controller correctly and extend the battery life:

1. Check the charge level when you turn on. If the phone turns on, look at the percentage at the top of the screen. If the charge is below 20%, you better start charging right away.
2. Use the original adapter and cable. If you don't have one, choose a certified Quick Charge 3.0/4+ or Turbo Charge (for Redmi Note 12 Pro+, Xiaomi 12T and later).
3. Connect your phone to charge and wait 100 percent. Don't interrupt the process even if the phone is heating up (within normal limits).
4. Once you reach 100%, turn off charging and use your phone as normal up to 20-30%.
5. Repeat the charge cycle to 100% another 1-2 times, which will help the controller to more accurately determine the actual capacity of the battery.

Important: If your Xiaomi supports adaptive charging (like the Xiaomi 14 or Mix Fold 2), turn it on in the settings. It automatically limits charge to 80% at night and brings it up to 100% by morning, which reduces battery wear.

For fast-charging models (120W in the Redmi Note 12 Pro+, 67W in the POCO F5), the first charge can take as little as 15-20 minutes.That's fine - modern Xiaomi controllers are optimized for high currents.

What adapters and cables can be used for the first charge

One of the most common questions is: can you charge the new Xiaomi with a non-original charger? Answer: Yes, but with reservations. Here is the compatibility table for popular models:

Key rules for choosing a charger:

• ⚡ Power: Must be no lower than the specification of the phone. 13T (67W) adapter 65W or 100W, not 18W.
• 🔌 Protocol: Quick Charge is required for fast charging 3.0/4+ or Power Delivery (PD). Cheap no-name adapters often don’t support these standards.
• 📱 Cable: Use USB-C — USB-C (Type-C models or original Micro-USB cable (for older Redmi models) 7A similar).

⚠️ Note: If you are using charging from another device (such as a laptop or tablet), make sure that it does not exceed the maximum power allowed for your Xiaomi (96W) It is theoretically compatible with Xiaomi 14 (90W), It can cause overheating with prolonged use.

💡

To check the actual charging power, install the AccuBattery app (available on Google Play) that will show the current, voltage and temperature of the battery in real time.

What to do if Xiaomi phone doesn’t charge on first connection

Situation: You plugged in a new Xiaomi to charge, but the indicator doesn't burn, and the charge level doesn't change.

• 🔌 Problem with cable or adapter: Try another cable (preferably original). Check the adapter on another device. Clear the port USB-C dust with a toothpick (carefully!).
• 📱 Phone discharged to zero: Wait 10-15 Minutes -- sometimes deep discharge takes time to wake up the controller (5V/1A) — Some models do not accept fast charging when 0%.
• ⚠️ Hardware defect: If the phone doesn't respond to charging for more than an hour, contact the service center.Power controller may be in trouble.

Pay special attention to models with dual battery (for example, Xiaomi 11T Pro or Mix Fold), in which the two cells are connected in series, and in deep discharge may require a special charger from the manufacturer.

💡

If the new Xiaomi isn’t charging, check the cable and adapter first, then try low-current charging (5V/1A).

In rare cases, the problem may be in the firmware, for example, in the Xiaomi 12S Ultra, there was a bug that caused the phone to not recognize some adapters, and this was solved by updating MIUI to the latest version.

How to extend the life of Xiaomi battery after the first charge: 5 rules

To make your Xiaomi battery last longer (and modern batteries lose ~20% of capacity in 2 years), follow these guidelines:

1. Avoid extreme temperatures. The optimal range for lithium polymer batteries is 10°C to 35°C. Charging in the cold (-10°C) or in the heat (+40°C) accelerates degradation.
2. Keep the charge in the range of 20-80%. Constant charge to 100% and discharge to 0% reduce the lifespan. Turn on adaptive charging in the settings (if any).
3. Use original or certified adapters. Cheap charging can deliver unstable voltages that harm the controller.
4. Update MIUI. Newer versions of firmware often optimize power management algorithms, for example, MIUI 14 added Battery Health to monitor wear.
5. Calibrate the battery every 3 months. Discharge the phone to 0% (until it turns off), then charge to 100% without interruption.

For models with larger batteries (5,000 mAh or higher, as in the Redmi Note 13 Pro+), it is especially important to avoid overheating. The fast 120W charging is convenient, but it is best to use it only when it is really necessary.
