You just unpacked the new Xiaomi Redmi 10 and want its battery to last as long as possible without losing capacity?First charging is a critical step that many users miss out on, following myths like βyou need to discharge to 0% before you first charge.β In fact, lithium polymer batteries (which are the ones in the Redmi 10) require a completely different approach.
In this article, we will analyze the official recommendations of Xiaomi, data from the technical documentation for the model. M2101K7AG (Redmi 10, as well as the results of tests of the DXOMark laboratory on battery degradation. Youβll learn how to properly βswingβ your battery in the early days, which chargers to use, and why charging up to 100% in heat reduces battery life 30% faster than at room temperature.
1.The first charge: myths and reality for Redmi 10
Older nickel-metal hydride batteries did require a full discharge before first charging, but the Xiaomi Redmi 10 is equipped with a 5,000 mAh lithium polymer battery (model). BM47), And this is what's happening, and it's not just useless, it's harmful:
- π Myth: "You have to discharge to 0% and charge to 100% 3 times in a row." Reality: This leads to a stress test for the power controller and accelerates cell degradation.
- β‘ Myth: "The first charge should last 12 hours." Reality: Modern smartphones automatically turn off power when they reach 100%, and recharging is impossible thanks to the built-in power supply. BMS (battery-control).
- π Myth: "Laptop charging ruins the battery." Reality: Redmi 10 supports Quick Charge 3.0, but is limited to 18 watts.
So how do you charge Redmi 10 for the first time?
Use the original charging (18W, model) MDY-11-ED>)|Connect your phone at 20-30 charge level%|Charge up to 80-85% without interruption|Turn off the power and let the battery βrestβ for 10-15 minutes.|Repeat the cycle 2-3 times in the first days of use-->
Why 80 to 85 percent? Because the voltage on the battery cells rises dramatically after 80 percent of the charge, which accelerates wear and tear. In the lab, batteries that charge up to 85 percent lost just 2 percent of their capacity in a year, while those charged up to 100 percent lost 20 percent.
2. Optimal charging parameters: voltage, current and temperature
Xiaomi Redmi 10 supports Quick Charge 3.0 technology USB Power Delivery, but that doesn't mean you always have to use maximum power. Let's figure out which options are safe for the battery:

|---|---|---|---|
| Voltage (V) | 3.8β4.2 V | >4.4 V | Overheating, battery bloating |
| Current (A) | 1.5β2.0 A | >3.0 A | Accelerated anode degradation |
| Temperature (Β°C) | 10β35Β°C | >45Β°C or <0Β°C | Irreversible loss of capacity |
| Charge level (%) | 20β80% | 0 or 100 percent | Reduce charging cycles |
According to internal Xiaomi documents, the Redmi 10 battery loses up to 15% of capacity per year if it is regularly charged at temperatures above 40.Β°C. To avoid overheating:
- π‘οΈ Do not charge your phone in direct sunlight (for example, on a windowsill).
- π₯ Remove the case while charging - it can block the heat sink.
- βοΈ Do not use your phone to play games or shoot videos while charging (helio processor load) G88 heats up).
π‘
If the phone gets too hot during charging, disconnect it from the network and let it cool to 30-35Β°C. Check the temperature through the engineering menu: type ##4636## β Β«Battery informationΒ».
3. What Charge to Use for Redmi 10: Original vs Alternatives

| Charging from the iPhone (5W/12W) | 10 Watts. | β οΈ Conditionally. | Slow charging but safe |
| Charging from a MacBook (29W/61W/96W) | 18 W. | β Yes. | Uses it. USB-PD |
| Nameless charging (e.g, Β«5V 2.4AΒ») | 10-12 W. | β No. | Risk of voltage spikes |
β οΈ Note: If you are using a charge higher than 18W (e.g, 30W or 65W), Redmi 10 will automatically limit consumption to safe values, but cheap cables without certification. USB-IF may cause the connector to overheat USB-C.
How to check if charging is working correctly? Install the AccuBattery app (available on Google Play) and check:
- Charging speed (should be in the range of 15-18 W at 20-80%).
- Battery temperature (not higher than 40)Β°C).
- Voltage (stable 4.2-4.3 V on full charge)
4.How to "swing" the Redmi 10 battery: calibration and charging cycles
The term "rocking" is often misunderstood, but it's actually about calibrating the battery controller, which is a process where the system learns to pinpoint the level of charge. This is especially important for the Redmi 10, because it's equipped with a function. MIUI Battery Optimization, which can show inaccurate data without proper calibration.
Hereβs how to do it without harming your battery:
Charge your phone to 100% and hold it for 1 hour|Turn off the power and use the phone until it is automatically turned off (0%)|Do not turn on the phone for 5-6 hours|Charge to 100% without interruptions|Repeat the cycle 1 time (no more often!)-->
β οΈ Attention: Kalibration is enough to be done once every 3 months or after updating the firmware. Frequent discharge to 0% accelerates battery degradation! β Battery β Usage statistics.
Also, look at the charging cycles. One full cycle is a discharge from 100% to 0%. However, the Redmi 10 is designed to run 500 to 800 cycles when used correctly.
- π Avoid frequent microcharges (e.g., recharge from 80% to 85% every 30 minutes).
- π± Do not keep your phone on charge all night β after 100%, the battery goes into βrechargingβ mode, which creates an extra load.
- π Use the Optimized Charging function in Settings β Battery (limits charge to 80% at night).

5 Common bugs that kill Redmi 10 battery
Even if you follow the basic rules, some habits can quietly shorten battery life. TOP-5 Redmi 10 owners errors identified by Xiaomi service centers:
- Using your phone while charging for resource-intensive tasks, such as playing Genshin Impact or shooting video in the video. 4K heats up the Helio processor G88 up to 60-70Β°C, which in combination with charging leads to thermal throttling (automatic performance reduction) and accelerated battery degradation.
- If you leave the Redmi 10 with 0% charge for 2-3 weeks, the battery can lose up to 30% of capacity due to deep discharge (voltage drops below). 3.0V).
- Use of uncertified cables, cheap unlabeled cables USB-IF may have incorrect resistance, which leads to surges of current and overheating of the connector USB-C.
- Disable battery optimization in settings. MIUI Battery Optimization limits the background activity of applications, which reduces battery load%.
- Charging from USB-A low-quality car adapter or computer port often produces unstable voltages (e.g., a low-grade car adapter, 4.7V instead 5V), which leads to pulsating current - one of the main causes of battery bloating.
How do you avoid these mistakes? Here's a quick memo:
π‘
The rule of thumb is that the Redmi 10 battery is afraid of three things: high temperature, deep discharge and unstable voltage. Control these parameters, and the battery will last 3-4 years without noticeable loss of capacity.
6. Additional settings MIUI battery life extension
Xiaomi Redmi 10 is working on the MIUI (The version depends on the region, but most often it is MIUI 12.5. MIUI 13), which offers a few hidden features to optimize charging.Here are the settings worth changing:
- Adaptive Charging is located in the Settings β Battery β Battery settings: This feature analyzes your habits and limits your charge to 80% at night, bringing it up to 100% just before waking up.
- Background activity restriction. Go to Settings β Annexes β Application management β Autorun and disable autorun for unnecessary applications (such as games or social media).
- Power saving mode. Included in Settings β Battery β Power saving mode: Limits processor clock speed and screen brightness, but significantly extends the running time.
- Turning off the always active display (Always-on Display) This feature (if enabled) consumes up to 5% of the charge per night. β Screen. β Always-on Display.
It's also useful to calibrate the battery sensor through the engineering menu.
- Enter the code ##4636##.
- Select Battery Information.
- Check the level (charge level) and voltage (voltage).
- If the values are very different from the real values (for example, it shows 100% and the phone turns off), perform a calibration (see section 4).
