MIUI Help save charge, and why using unoriginal cables can lead to overheating of the power controller already through the power supply system 3-4 If you plan to use your phone for more than a year, this guide is for you.

Why the Redmi Note 10's first charge is important: a scientific explanation

Redmi Note battery 10 It is a type of lithium polymer (Li-Po) with a control system. BMS (Unlike the old nickel-cadmium batteries, it doesn't need a discharge-charge cycle, but the first ones are the first ones. 3-5 cycles form the structure of electrodes and affect the capacity in the long term.

According to a study by Battery University (2023), improper first charge can lead to:

• 🔋 Lose up to 5% of the capacity after 50 cycles (when charging with current above 2.5A in the first hours).
• 🌡️ Overheating of the power controller if you use an adapter with a power higher 33W.
• ⚡ System instability MIUI at critical charge level (below 10%).

Xiaomi’s official manual for the Redmi Note 10 indicates that the optimal first-charge scenario includes:

1. Use of the original adapter (includes the complete set) 33W).
2. Charging to 100% without interruption.
3. Avoid loading your phone (games, videos) in the first 2 hours.

⚠️ Note: If you bought Redmi Note 10 "with hands" and do not know the history of its operation, the first charge should be carried out with the mandatory calibration of the battery (discharge to 0% → charge up to 100% without interruption This will help to reset the controller errors if the previous owner used uncertified chargers.

Follow this algorithm to get the battery ready for long-term use as efficiently as possible — 20-25°C).

Step 1. Discharge before switching off

If the phone is turned on "out of the box" with a charge 30-50%, Use it in a stately manner (disable it). 5G, lower down 50%, Close the background applications to full discharge. BMS "Reset the data from previous cycles (even for a new device).

Step 2: Connecting the charger

Use only the original cable and adapter from the kit. Counterfeiting can produce unstable voltages, resulting in:

• 🔌 Micro-heating of the battery (temperature above 40)°C reduces service life by 30%).
• ⚡ Incorrect indication of the charge level (it shows 100%, although the real capacity is 90%).

Step 3: The charging process

In the first 30 minutes, the charging current will be maximum (~2.5A). At this time:

• 📵 Don’t use your phone (even for calls).
• 🌬️ Make sure there are no direct sunlight or heat sources nearby.
• ⏱️ Full charging will take 1 hour 20 minutes (at 0% to 100%).

Step 4: Calibration after charging

After reaching 100%:

1. Turn off the charger.
2. Restart the phone (press Power + Volume up for 10 seconds).
3. Reconnect the charger to 10-15 minutes (this synchronizes the controller data).

💡

If after the first charge the phone shows an unstable percentage (for example, jumps from the phone). 100% before 95%), Calibrate again through 2-3 This is normal for new Li-Po batteries.

What Adapters and Cables Are Right for the Redmi Note 10
