You've just unpacked Xiaomi's new smartphone -- whether it's the flagship Xiaomi 14 Ultra, the budget Redmi Note 13, or the gaming Black Shark 6. The first thing that comes to mind after you set up is how to charge your battery for the first time? There's a lot of conflicting information going on the Internet, from "discharge to zero" tips to "training cycles," and we'll figure out what's relevant for today's lithium polymer batteries and what's long gone.
Xiaomi’s current smartphones are equipped with Li-Po batteries that don’t require any “swinging” or special first charge. However, doing the right thing in the early days can affect battery life. This article is only validated data from official Xiaomi sources and battery chemists’ research, without any speculation.
Myths about the first charge: what is true of this?
The most common myth is that the new battery should be “discharged to 0% and charged to 100% 3 times in a row.” This advice was relevant for nickel-metal hydride (Ni-MH) batteries 20 years ago, but absolutely meaningless for modern Li-Po. Moreover, deep discharge accelerates the degradation of lithium cells from the first cycle.
Other popular misconceptions:
- 🔋 "First charging should be carried out only with the original charger – Xiaomi allows the use of certified third-party adapters with Quick support Charge/PD.
- ⚡ "Charge strictly 8 hours" - modern controllers turn off power when reaching 100%, further stay in the socket only warms the battery.
- 📱 "You can not use your phone during the first charge - there are no restrictions, but intense loads (games, videos) will slow down the process.
The only thing that really matters is to avoid overheating and deep discharge in the first weeks, and lithium polymer batteries are most vulnerable in the initial phase of operation.
Xiaomi’s official position: what the manufacturer says
Xiaomi’s user manuals (e.g., Xiaomi 13T Pro or POCO X6 Pro) clearly state, “Put the first charge in a standard way, without special procedures.” The company emphasizes that modern batteries are factory calibrated and ready to work “out of the box.”
In the official support section, Xiaomi recommends:
- Use an original or certified charging adapter.
- Avoid charging at temperatures below 0°C or above 40°C.
- Do not leave your phone on charge for more than 24 hours in a row.
Interesting fact: Xiaomi labs test batteries on 800 full cycles (discharge-charge up to 100%) with 80% capacity, equivalent to 3-4 years of heavy use, and this can only be achieved with care from day one.
💡
If you have a charger with your Xiaomi that says Surge P1 or Surge G1, these are branded fast-charging chips, which optimize the process and reduce battery heat.

The algorithm is simple, but it requires attention to detail.
- Unpack your smartphone and turn it on. Usually, new Xiaomis have a battery charge of 40-60% – enough for initial setup.
- Go through the initial setup (language selection, Wi-Fi connection, Mi Account login) and it takes 10-15 minutes and slightly drains the battery.
- Connect the original charger to the socket, then the USB-C cable to the phone. Use the USB-C port on the charger (if there are more than one).
- Charge to 100% without interruption. The first full charge helps the battery controller to "remember" the real capacity.
- Turn off the network when the indicator is 100%. Don't leave it on the charge "just in case".
Use the original cable and adapter | Charge at room temperature (15-25°C) | Do not interrupt the process to 100% | Disconnect after full charging | Avoid games/video while charging-->
For models with fast charging support (Xiaomi 12S Ultra, Redmi K70 Pro), the first cycle can be performed in standard mode (without activating the Turbo Charge).
What to do after the first charge: optimal mode
The first cycle is just the beginning. To make the battery last longer, stick to these rules in the first weeks:
- 📉 Avoid a discharge below 20%. Lithium polymer cells degrade faster at deep discharges. Xiaomi has built-in protection, but it's better not to trigger it.
- 🔌 Don't hold it 100 percent long. If the phone is fully charged, disconnect it from the grid.Constant maintenance 100 percent speeds up battery aging.
- 🌡️ Watch the temperature. Optimal range — 10-35°C. When charging above 40°C activated protective mechanisms that limit the current.
- 🔄 Calibrate the battery once every 3 months: discharge to 0% (until the phone turns off) and charge to 100% without interruptions.
Xiaomi’s MIUI 14+ smartphones have a built-in Smart Charging feature (Settings → Battery → Battery Settings) that automatically limits your charge to 80% and brings it up to 100% just before your normal wake-up time (based on habits analysis), which extends battery life by 20-30%.
How to turn on Smart Charging on Xiaomi?
Table: Comparison of first-charging methods
| Method | Impact on the battery | Xiaomi Recommendation | Applicability in 2026 |
|---|---|---|---|
| Discharge up to 0% + 3 cycles up to 100% | ❌ Accelerates the degradation of Li-Po | ❌ Forbidden. | Outdated (for Ni-MH) |
| Charging to 100% without discharge | ✅ Optimal for calibrating the controller | ✅ Recommended | Relevant. |
| Charging up to 80% from day one | ⚠️ Reduces display capacity (not real) | ⚠️ Not necessarily. | Suitable for "smart" charging |
| Use only the original charger | ✅ Optimal current/voltage | ✅ Recommended | Relevant (but certified analogues are acceptable) |
| Charging with the phone turned off | ⚠️ Faster, but without temperature control. | ⚠️ Not prohibited, but not necessarily | It's okay, but not critically. |
The table shows that the only method Xiaomi has approved is standard charging up to 100% without pre-discharge, all other options are either outdated or do not offer benefits.
Frequent Mistakes and How to Avoid Them
Even experienced users sometimes make mistakes when they first charge, and here are the most common ones:
⚠️ Warning: Never use chargers with higher output voltage 5V/3A (For example, laptop charging 20V), If your Xiaomi does not support you USB-PD. This can cause the power controller to fail.
- 🔌 Use of damaged cable, microcracks in the squirt or bent connectors USB-C They cause unstable current and overheating.
- 📵 Charging at low network signal, under poor coverage (1-2 dividing the antenna – the phone spends additional energy searching the network, which increases the heating.
- 🎮 Playing Genshin Impact or Call of Duty Mobile while charging creates peak battery loads, temperatures could exceed 45.°C.
- ☀️ Charging in the sun or in the car, even at room temperature in the cabin of the car in the summer can be 50-60°C, which is critical for Li-Po.
If you notice that the battery is running out too quickly after the first charge (for example, the Xiaomi 13 Lite loses 10% per hour in standby mode), reset the battery statistics:
- Go to Settings. → Battery → ⚙️ (gear-plate) → Resetting battery statistics.
- Connect the charger and wait 100%.
- Turn off and use your phone before automatically turning off (0%).
- Charge again to 100% without interruption.
💡
Resetting battery statistics does not restore physical capacity, but only corrects the data of the controller. If the battery wear is real (for example, 2 years of use), only replacement will help.
Specifics for different Xiaomi models
Some Xiaomi series have features that are worth considering when first charging:
- 📱 Flagships (Xiaomi) 14, 13T Pro, Mix Fold 3): Supporting. 120W/200W HyperCharge. For the first charge, it is better to use the standard mode (Settings) → Battery → Charging mode → Standard) to reduce heat.
To check the real capacity of the battery, enter the combination in the "Phone" application:
##4636##Go to Battery Information. The charge level option should match the indicator in the status bar (accuracy up to 2% is acceptable).
