You just unpacked the new Xiaomi Redmi Note 10s and wonder how to charge it for the first time? There are dozens of controversial tips online, from "require to discharge to 0%" to "keep charging for 12 hours." Most of them are outdated myths that are not relevant to today's lithium-polymer batteries. In this article, we'll look at what's really important when you first charge, and what's worthless remnants of the past.
The Redmi Note 10s is equipped with a 5,000mAh battery with 33W fast charging support. The manufacturer has already optimized the charging process in the factory, so no “special rituals” are required. However, there are a few nuances that will help maximize battery life from the first day of use.
Myths about the first charge: what is actually harmful to the battery
Many users still follow the advice that is relevant to nickel-cadmium batteries 20 years ago, and here are some common misconceptions that are not only useless, but also harmful to the Redmi Note 10s:
- 🔋 "You have to completely discharge your phone before you charge it, which destroys the lithium polymer cells".
- ⏳ "Charge 12 hours in a row" - recharging is harmful. Smartphone automatically turns off power when you reach 100%.
- 🔌 "Use only original cable – it is important to maintain power (33W), But quality certified cables from other brands will do.
- 📵 "You can’t use your phone while charging, but intense games or video editing will slow the process down.
The most dangerous myth is the use of “training cycles” (full discharge-charge 3 times in a row). For the Redmi Note 10s, this is not only pointless, but also reduces battery life. Xiaomi officially declares that the first charge is no different from the next one.
Xiaomi’s official instructions: how to charge Redmi Note 10s for the first time
The Redmi Note 10s user manual (page 47) states, "Use the original charger for the first charge and connect the phone to the network when the charge level drops to 20% or below." Here is a step-by-step algorithm approved by the manufacturer:
☑️ First charge of the Redmi Note 10s
It takes about 1 hour and 20 minutes (using the original 33W RAM). If you use a lower power adapter (e.g. 18W), the time will increase to 1 hour and 50 minutes. Don't interrupt charging halfway, which is not critical, but it's better to bring it to 100% the first time.
⚠️ Warning: If the phone gets too hot while charging (above 40)°C), immediately disconnect it from the network.This may indicate a battery failure or use of an uncertified charger.
What happens if you ignore the recommendations of Xiaomi?
Many users dismiss the manufacturer's advice as a "marketing ploy," but ignoring the basic rules can lead to the following consequences:
| Action. | Short-term effect | Long-term effects |
|---|---|---|
| Use of RAM >33W | Accelerated charging (up to 80% in 30 minutes) | Battery overheating, lifespan reduction by 15-20% |
| Charging below 0°C | Slow charging, possible failures | Irreversible electrolyte damage |
| Constant charging up to 100% with subsequent connection | The phone is working fine. | Reduced battery capacity by 30% in 1-2 years |
| Use of damaged cable | Unstable nutrition, reboots are possible | Risk of short circuit and fire |
The critical mistake is to leave the phone on charge all night long, and while the Redmi Note 10s has overcharging protection, maintaining 100% charge at high temperatures accelerates battery degradation, and the optimal range for everyday use is 20 to 80 percent.
💡
Turn on the Optimized Charging feature in your battery settings (Settings → Battery → Optimized Charging) and it will automatically limit your charge to 80% at night and recharge to 100% by waking up.
How to check if the battery is charging properly
After connecting the charger, pay attention to the following indicators:
- ⚡ Lightning sign in the status line - confirms that there is a charging.
- 🔄 The percentage of charge should increase by 1-2% per minute (at the same time). 33W).
- 🌡️ Body temperature - light heat is permissible, but not a hot back panel.
- 📊 Battery status in Settings → Battery → The state of the battery should be "good".
If charging is too slow (less than 1% per minute) or your phone doesn’t recognize the charger, follow these steps:
- Check the cable for damage.
- Clean the USB-C port of dust with a toothpick (carefully!).
- Reboot the phone.
- Try another charger with Quick Charge 3.0 support.
⚠️ Warning: If after these actions the problem persists, do not use the phone before visiting the service center.Continuing to charge with a faulty adapter may cause the battery to bloat.
Additional settings to extend battery life
In addition to the correct first charge, the Redmi Note 10s has several features that will help to save battery capacity:
How to turn on the energy saving mode?
- 🔄 Adaptive charging – takes into account your habits and optimizes cycles (Settings) → Battery → Adaptive charging).
- 📵 Background Limitation – Closes unused applications (Settings) → Annexes → Permits → Auto-start).
- 🌙 Dark topic – reduces energy consumption AMOLED-10-15 screen%.
- 🔍 Optimize location – turn off GPS for applications that do not need it.
It is also recommended to update the firmware to the latest version. Updates often add power optimizations. For example, MIUI 14 for Redmi Note 10s improves the background, which gives +5% autonomy.
💡
Regular battery calibration (full discharge-charge every 2-3 months) helps to reset the errors of the power controller. But do not abuse this - 1 time per quarter is enough.
Frequent User Mistakes and How to Avoid Them
Even experienced smartphone owners sometimes make mistakes that shorten battery life.
- 🔌 Using “cheap” cables – they may not support Quick Charge 3.0 protocol, which makes the phone charge slower and warm up more strongly.
- ☀️ Charging in the sun or in the car in summer - temperature above 40°C causes irreversible damage to the battery.
- 🎮 Games while charging - Redmi Note 10s heats up to 45-50°C, which is critical for the battery.
- 🔋 Storage of a discharged phone – if left with 0% for a month, the battery may fail.
Another common mistake is using wireless charging, and although Redmi Note 10s doesn't support it, some users buy adapters, which is not only useless (charging speeds will be lower), but also dangerous because of the risk of overheating.
