Why Xiaomi’s First Charge Is So Many Questions
You just unpacked Xiaomi’s new smartphone — whether it’s the Redmi Note 13 Pro+, POCO X6 or Xiaomi’s flagship 14 Ultra — and you’re faced with a dilemma: How to charge it for the first time? There are dozens of controversial tips online, from “discharge to 0%” to “keep it charging for 12 hours,” most of them remnants of the nickel-metal hydride era that have long been out of use in modern smartphones.
Modern lithium polymer batteries (Li-Po) installed in Xiaomi devices do not require complex “swing” procedures or many hours of first charging. However, there are nuances that will help to maximize battery life from day one. In this article, we will analyze the official recommendations of the manufacturer, debunk myths and give clear instructions – without water and outdated tips.
It’s important to understand that the first charge does not directly affect battery capacity, but it forms user habits that further determine how quickly the battery degrades, such as using fast charging at maximum or discharging until completely shut down reduces battery life by 20-30% in the first year.
Xiaomi’s official position: what the manufacturer says
The user manuals for Xiaomi smartphones (including the models from 2023-2026) do not contain separate instructions for “first charging”. The manufacturer recommends that you adhere to the general rules for the operation of lithium polymer batteries, which are universal for all modern devices.
- 🔋 Use the original charger and cable from the kit. For models with HyperCharge support (e.g. Xiaomi) 12T Pro) this is critical - non-original adapters may not provide the correct charging speed.
- 📱 The first charge can be started immediately after unpacking, regardless of the charge level (even if the indicator shows the first charge). 50-60%).
- ⚡ No "full cycle" is required (down to 0% → 100% charge is a myth that is relevant to older types of batteries.
- 🔄 Optimal charge range for battery life: 20-80%. Continuous charging until 100% precipitate.
Interestingly, Xiaomi service centers confirm that up to 70% of battery warranty replacements are due to improper operation in the first months of use, such as leaving the phone on charge overnight or using cheap powerbanks with unstable voltages.

The algorithm is simple, but it requires attention to detail. Follow these steps to avoid the typical mistakes:
- Check the charge level when you turn on. If the phone shows ≤15%, connect the charge immediately. If ≥50%, you can use the device to a discharge of up to 20-30%, and then charge.
- Use the original adapter. For models with Fast Charge (for example, Redmi Note 12 Pro+), a 67W or 120W unit from the kit will suit. For budget Redmi A2, 10W will suffice.
- Connect the cable to the phone, then to the socket (not the other way around!) This reduces the risk of a power surge.
- Charge to 80-90% for the first session. Full charge to 100% is acceptable, but not mandatory.
- Turn off charging when the phone heats up to ≥40°C (check Settings → Battery menu).

A tip for owners of Xiaomi with wireless charging (for example, Xiaomi 13 Pro or Mix Fold 3): the first charge is better to conduct over the cable. Wireless stations often heat the case more strongly, which is undesirable for a new battery.
⚠️ Note: If the Xiaomi phone does not turn on after purchase or shows 0% charge and does not respond to charging, do not try to “overclock” the battery with multiple connections.
Myths about the first charge: what actually harms the battery
Let’s take a look at the common misconceptions that still haunt social media and forums:
| Myth | Reality. | Consequences of following the myth |
|---|---|---|
| "You need to discharge to 0% and charge to 100% 3 times in a row" | The current Li-Po battery is not a memory effect (before 2005). | Deep discharge reduces battery life by 1-2% per cycle |
| "The first charge should be done for 12 hours." | The charge controller automatically shuts down power at 100 percent, and then you recharge to compensate for self-discharge. | Overheating and Excess Stress for the Battery |
| You can’t use your phone during the first charge. | It is possible, but not recommended to load the processor (games, videos) | The temperature increases, which accelerates the degradation |
| “We need to calibrate the battery with special applications.” | No manual calibration is required – the battery controller does it automatically | “Calibration” applications often contain malicious code. |
The myth of “12-hour charging” is particularly harmful: Xiaomi smartphones (like other manufacturers) go into trickle charging mode after reaching 100%, which is slow charging to compensate for natural self-discharge. Keeping the phone on charging for longer than 1-2 hours after 100% is pointless and harmful.
Why did the instructions on the old phones say 12 hours?
Optimal charging settings for new Xiaomi smartphones
Xiaomi smartphones based on MIUI 12 and later have built-in tools to extend the life of the battery. Here are the settings you should activate immediately after the first charge:
- Turn on “Optimized Charging”: Path: Settings → Battery → Battery Settings → Optimized Charging Function limits charge to 80% at night and brings it up to 100% by your wake-up time (manually configured).
- Turn off fast charging on a continuous basis (optional): Path: Settings → Battery → Battery settings → Fast charging If you don’t rush, charge in 5W-10W mode – this reduces heat and battery stress.
- Activate Battery mode in Performance settings: Path: Settings → Special features → Performance → Battery mode Limits background activity and reduces heating.
For models with Surge chips (such as the Xiaomi 12S Ultra), the Smart Balancing feature is available, which distributes the load between two batteries (if any).
💡
If your Xiaomi supports Reverse Charging, don’t use this feature in the first 2-3 weeks. it heats the battery a lot, which is not desirable for a new battery.
What to do after the first charge: further battery care
The first charge is just the beginning. To ensure that the battery lasts 3-4 years without noticeable degradation, adhere to these rules:
- 🔄 Avoid full cycles (0-100%). Optimally keep the charge in range 30-80%.
- ☀️ Don't leave your phone in the sun or in your car in the summer.Temperatures above 35°C accelerates degradation by 2 times.
- 🔌 Use high-quality powerbank and support PD/QC (Xiaomi Mi Power Bank, for example 3). Cheap batteries give out unstable voltage.
- 📵 Turn it off. 5G and wifi 6, If you don't need them, these modules increase the energy consumption of the 15-20%.
- 🔋 Once every 3 months, do a full cycle (discharge to 5% → charge up to 100%) for the calibration of the controller.
For Xiaomi owners with graphite anodes (Silicon-Oxide Anode technology, used in Xiaomi 11T Pro and later), it is important to avoid deep discharge (below 10%), such batteries are more sensitive to low voltage, but better tolerate fast charging.
⚠️ Note: If after the first charge, the Xiaomi phone discharges too quickly (for example, loses 20% per hour in standby mode), check the background processes in Settings → Battery → Battery use: Apps like Facebook or TikTok are often to blame, which consume energy even in the background.
Frequent Mistakes and How to Avoid Them
Even power users sometimes make mistakes that shorten battery life.-5 Failures and How to Avoid Them:
- Using your phone while charging for games/video CPU load + charging = overheating. Temperatures above 45°C cause irreversible damage to the battery. Solution: If you need to call urgently, remove the case for better cooling.
- Charging via a laptop or old USB 2.0 PC USB port only gives 0.5A, causing a charge controller malfunction.Solution: Use the original adapter or a certified USB-C PD hub.
- If you leave Xiaomi on a shelf with 0% charge for a month, the battery can lose up to 50% of capacity. Solution: Before long storage, charge up to 50% and turn off the device.
- Ignoring MIUI Updates In newer versions of firmware, power management algorithms are often optimized. Solution: Update through Settings → About Phone → System Update.
- Use of "energy-saving" applications of the Program, such as DU Battery Saver or Clean Master often closes background processes aggressively, leading to services reboot and increased battery consumption.Solution: Use built-in tools MIUI.
💡
The most common mistake is ignoring overheating: If the Xiaomi case is hot to the touch while charging, immediately turn off the power and let it cool. Repeated overheating reduces battery life by 3-4 times.
