You just unpacked Xiaomi’s new smartphone — whether it’s Xiaomi’s flagship 14 Ultra, the budget Redmi Note 13, or the gaming Black Shark 6. The first thing to do after setting up is to charge the battery correctly. There are a lot of conflicting tips on the Internet: some say that the first charge should be stretched out for 12 hours, others that 20 minutes is enough. Who’s right? In this article, we will analyze Xiaomi’s official recommendations, scientific data on lithium-ion batteries and common myths that only harm your gadget.
Spoiler: Xiaomi smartphones today don't require a first-time battery pumping -- a relic of the nickel-metal hydride battery age -- but there are nuances that can extend battery life by 20-30%. Next, just the facts and specific instructions for the 2022-2026 models.
Myths about the first charge: what actually harms the battery
Forums and social media often feature tips like “charge your phone for 12 hours straight” or “discharge to 0% before first charging” that are at least 15 years old. Xiaomi smartphones today are equipped with lithium polymer batteries that do not have a “memory effect” – a problem that is relevant to older Ni-MH batteries – and that can accelerate battery degradation.
Here are the most common misconceptions and their exposure:
- 🔋 "You need to completely discharge the smartphone before the first charge" → On the contrary, deep discharge (below) 3%) Reduces battery life: Xiaomi recommends keeping charge in range 20-80%.
- ⏳ "The first charge must be stretched to 8-12 hours" → It's pointless: the charging controller automatically turns off power when it reaches 100%. Recharging is impossible.
- 🔌 "Charge only with the original charger" → It is important to observe the power (W) and the standard (Quick Charge, PD). High-quality certified chargers of third companies (for example, Anker or Baseus) are not worse than the original ones.
- 📵 "You cannot use your phone while charging" → You can, but intense tasks (games, video editing) heat the battery, which speeds up its wear and tear.
The advice about “long first charge” is particularly harmful, because lithium-ion batteries degrade not from the number of cycles, but from the time they are in a high voltage state (close to 100%), so if you leave your phone charging for 12 hours, the battery will spend extra hours under maximum load — the equivalent of a few dozen normal charge cycles.
Xiaomi’s official instructions: what the manufacturer says
Xiaomi doesn’t publish separate guidelines for first charging, but the user manuals and support site have general battery maintenance guidelines. We analyzed the documents for the Xiaomi 13T, Redmi Note 12 Pro+ and POCO F5 models — the essence is the same everywhere.
⚠️ Attention: In the instructions for Xiaomi smartphones 2023-2026 In the years since there is no mention of a "special first charge", the manufacturer recommends that the general rules of operation of the battery be followed from the first day.
- 📱 Use the original cable and adapter (or certified Quick Charge-enabled analogues) 3.0/4+ or USB-PD).
- 🔋 Avoid full discharge - connect charging when 15-20% charge.
- ⚡ Do not keep on charging longer than necessary - after reaching 100% turn off the power.
- 🌡️ Watch the temperature: optimal range — 10-35°C. Overheating (>40°C) the charging shall be automatically suspended.
Fun fact: the Mi Battery & Performance app (available on most models) has a built-in Battery Optimization Mode that automatically limits the charge to 80% and allows full charge only before your normal wake-up time, which reduces battery wear by 40% according to Xiaomi Lab tests.
Unpack your smartphone and check the complete set (cable, adapter)
Make sure the temperature of the device is 15-35°C (do not charge immediately after delivery in winter!)
Connect the original cable to the adapter with fast charging support
Set up the basic settings (Wi-Fi, Mi Account) before charging-->

Now, let's get to the point. Here's the optimal first-charging algorithm, based on Xiaomi's recommendations and battery research data:
- Turn on your smartphone and complete the initial setup (language selection, Wi-Fi connection, Mi Account login) and it takes 10-15% of the charge, which is normal.
- Connect the charger to the socket, then the cable to the phone. Use the original adapter or certified analogue with power not lower than the specified model (for example, for Xiaomi 14 Pro – at least 67 watts).
- Charge to 80-85% is enough to start using. Full charging to 100% is permissible, but not mandatory.
- Turn off the charger after reaching the desired level. Do not leave the phone on the charge "just in case".
- Use your smartphone as normal, without aiming for full discharge. Connect charging at 15-20%.
For models that support wireless charging (for example, Xiaomi 13 Ultra or Xiaomi MIX Fold 3) the rules are the same, but consider that induction charging heats the case more.
💡
If you bought a Xiaomi smartphone in winter, let it heat up to room temperature (at least 1 hour) before first charging.The cold battery charges slower and may not calibrate correctly.
| Action. | Recommendation | Consequences of violation |
|---|---|---|
| Use of non-original charger | Only certified adapters with Quick Charge/PD support are allowed. | Overheating, unstable voltage, accelerated battery degradation |
| Charging below 0°C | Minimum temperature - 10 ° C (optimally 15-35 ° C) | Incorrect calibration of the controller, risk of damage to battery elements |
| Games/video editing during charging | Easy tasks (messengers, browsing) are allowed | Overheating to 45°C+, loss of capacity by 1-2% per cycle |
| Storage of the smartphone discharged (0%) | The optimal level for storage is 40-60% | Deep discharge can make the battery inoperable |
Features for different Xiaomi models
While the general principles are the same, some Xiaomi models have unique charging nuances.
Flagships (Xiaomi 13/14 Series, MIX Fold)
These smartphones support ultra-fast charging (up to 120 watts in the Xiaomi 14 Pro).
- 🔌 Use only the original adapter – third-party firms may not provide stable voltage.
- 🌡️ Watch the temperature: when charging at 120 W the body can heat up to 40°C. Remove the cover and do not cover the phone.
- ⚡ Include in the settings Settings → Battery → Fast charging.+ maximum speed.
Budget models (Redmi Note, POCO)
Here, charging power of 33-67 W is usually used.
- 📉 Lower capacity batteries (4000-5000 They charge faster, but they warm up more. 18-25°C.
- 🔄 Some models (like the Redmi Note 12) have an Optimized Charging mode – turn it on to extend the life of the device.
Gaming smartphones (Black Shark)
Black Shark 5/6 has a unique cooling system and support charging up to 120 watts.
- 🎮 Do not start games while charging – this cancels the effect of liquid cooling.
- ❄️ Use a radiator-case in the kit to remove heat.
- 🔋 In the game settings (Shark Space) turn off background activity when charging.
What if your smartphone isn’t charging for the first time?
How to extend the battery life from the first day
The first charge is just the beginning. To ensure that the battery lasts 3-4 years without noticeable degradation, follow these rules:
- Keep the charge in the range of 20-80%. Regular full cycles (0-100%) reduce the resource by 30-40% per year.
- Avoid overheating. Do not charge your phone in direct sunlight or near heat sources (such as on the dashboard of a car).
- Use original accessories. Cheap cables without certification can cause power surges.
- Enable battery optimization in settings (Settings → Battery → Battery Mode).
- Xiaomi regularly improves power management algorithms (for example, adaptive charging mode has been added to MIUI 14).
To check the status of the battery, use:
- 📊 Built-in statistics: Settings → Battery → Battery condition (shows wear in the %).
- 🔧 AccuBattery app (available on Google Play) – tracks charging cycles and temperature.
💡
The most important factor in battery durability is avoiding high temperatures, and every 10°C above 30°C doubles the rate of degradation of lithium-ion cells.
If you plan to store your smartphone without using it (like a spare machine), charge it up to 40-60% and disconnect. A fully discharged or 100% charged battery can fail if stored long.
Frequent Mistakes and How to Avoid Them
Even experienced users sometimes make mistakes that shorten battery life.
⚠️ Note: If you use powerbank for your first charge, make sure it supports Quick Charge or USB-PD. Cheap power banks without fast charging can deliver unstable voltage, which is harmful to the new battery.
- 🚫 Using your phone while charging in a hot room (such as a sauna or beach) causes overheating and permanent damage to the elements.
- 🚫 Charging through USB-The power is usually not enough (0.5-1 A) which increases charging time and may cause incorrect controller calibration.
- 🚫 Ignoring overheating warnings: If a notification appears saying "Battery temperature is high", immediately turn off the charge and let the phone cool down.
- 🚫 Keeping your smartphone on a standby charge, maintaining 100% charge, reduces battery life by 50% in 6 months.
Another common mistake is using smart sockets with a timer, where some users set up automatic charging shutdowns after 2-3 hours, believing it is useful, and in fact, it can interrupt the charging cycle at a critical phase (for example, when balancing cells), which will lead to incorrect calibration.
