Buying a new Xiaomi smartphone is always an exciting experience, but with the joy of the new device comes the question: how to charge the device for the first time to battery last as long as possible? On the Internet you can find dozens of controversial tips, from full discharge to 12-hour charging, but most of them are outdated or just myths.
Modern lithium-ion and lithium-polymer batteries, which are equipped with all Xiaomi models (from the budget Redmi to the flagship Xiaomi 14), do not require “pumping” or special charging cycles. However, the first charge still has its nuances, which are worth knowing. In this article, we will analyze the official recommendations of the manufacturer, debunk popular misconceptions and give practical advice based on data from Xiaomi engineers and independent research.
Myths about the first charge: what actually harms the battery
Many users still follow the advice of 2000s nickel metal hydride batteries, and here are some of the most common misconceptions and the truth about them:
- 🔋 "You need to completely discharge your phone before you first charge – this rule worked for older battery types, but for Xiaomi lithium-ion batteries, the deep discharge (below) 3-5%) harmful and shorten the service life.
- ⏳ "The first charge must be kept for 12 hours" - modern charge controllers automatically turn off power when reaching 100%, and recharging is impossible due to built-in protections.
- 🔄 "We need to do it. 3 Full cycles of charging-discharge is not only useless, but harmful: each full cycle (0-100%) reduces the battery life of ~0.1-0.3%.
- 🔌 "Charge can only be original charger" - important not the brand charger, and its power and support of Quick technologies Charge/Turbo High-quality certified third-party chargers (such as Anker or Baseus) are no worse than the original ones.
The most pernicious myth is the belief that first charging somehow “calibrates” the battery. In fact, all modern Xiaomi smartphones (since 2018) undergo factory calibration of the battery, and no additional manipulation is required. Moreover, artificially creating “stress” conditions (for example, heating the battery with long charging) only accelerates its degradation.
Xiaomi’s official instructions: what the manufacturer says
The user manuals for all Xiaomi models (including Redmi Note 12, POCO X5, Xiaomi 13T, etc.) clearly spell out:
⚠️ Warning: First charge requires no special action. Connect your phone to the charger using the original cable and wait for full charge (100%). Avoid using your phone during the first charge to speed up the process.
More detailed recommendations can be found in the documents for Xiaomi service centers:
- Use a charger with power corresponding to the phone model (for example, for Xiaomi 12 Pro – 120W, for Redmi 10A – 10W).
- Do not interrupt the first charge until you reach 100% (if possible).
- Avoid extreme temperatures: The optimal range for charging is 10-35°C.
- Do not use your phone for resource-intensive tasks (games, video editing) while charging, this causes overheating.
Fun fact: Xiaomi’s newer models (starting with the Mi 11) have AdaptiveCharge technology that automatically optimizes charging, for example, if you plug your phone in overnight, the system will charge it to 80 percent first, then wait until the morning hours to get to 100 percent, which reduces battery stress.

The algorithm is simple, but there are a few important details. Follow this guide to minimize the risks:
- Unpack your phone and check the kit. Make sure the original cable (usually USB Type-C) and charger (if your model has one) are in the box. For the European market, Xiaomi often doesn't put the charger in the kit - check this out in advance.
- Connect the charger to the outlet. Use a network filter or ground power supply to avoid power surges.
- Connect the cable to your phone. On models with an IR Blaster (like the Redmi Note 11), the connector can be slightly recessed — don't put too much effort into it.
- Wait for the charge indicator to appear. The battery icon with the charging animation should show on the screen. If the screen does not respond, try restarting the phone (power button + volume up for 10 seconds).
- Leave the phone to charge up to 100%. Time depends on the model: 📱 Redmi 9A (10W) — ~2.5 hours ⚡ POCO F4 (67W) — ~40 minutes. ⚡⚡ Xiaomi 12S Ultra (120W) — ~20 minutes.
Turn off the charger after reaching 100%
If you didn’t buy the phone (such as refurbished or handheld), the first charge is no different, but in this case, it is recommended to check the battery status through the Settings → Battery Status menu or using the AccuBattery app (available on Google Play).
What to do if the phone is not charging?
Optimal charging settings to extend battery life
To ensure that your Xiaomi battery lasts 3-4 years without noticeable degradation, adjust the following settings:
| Parameter | Recommended value | Why is it important? |
|---|---|---|
| Maximum level of charging | 80-85% | Reduces battery load. Included in Settings → Battery → Charging modes (available on models with MIUI 12+). |
| Fast charging. | Included (but do not use it constantly) | It speeds up charging, but heats up the battery, optimally: fast charging to 80 percent, then regular charging. |
| Temperature control | Limitation at >30°C | Overheating above 35°C destroys the battery structure. In hot weather, remove the case while charging. |
| Background processes | Limiting for unnecessary applications | Constant sync (like Facebook or TikTok) drains the battery even when it’s in standby mode. |
On models with MIUI 13/14, there is a hidden feature called Smart Charging (Settings → Special Features → Additional Settings → Smart Charging) that analyzes your habits and automatically limits charging to 80% if you, for example, normally charge your phone overnight, one of the most useful features for battery retention.
💡
If you often forget to turn off charging, set a reminder in Google Assistant or use an automatic timer socket (e.g. Xiaomi Mi Smart Plug).
Frequent User Mistakes and How to Avoid Them
Even experienced Xiaomi owners sometimes make mistakes that shorten battery life, and here are the most common ones:
- 🔥 Charging in the sun or near heat sources, like leaving your phone on a car torpedo in the summer. Temperatures above 40°C may irreversibly damage the battery.
- 🎮 Gaming while charging. Running Genshin Impact or Call of Duty Mobile loads the processor, which, along with charging, causes overheating.
- 🔌 Using cheap cables without certification, and these cables can not only slowly charge, but also damage the power controller. USB-IF.
- 🛌 All night charging. Even with AdaptiveCharge, it's best not to keep your phone connected for more than 8 hours at a time. The ideal option is to charge up to 80% before bed and bring it to 100 in the morning%.
⚠️ Warning: If the phone runs too fast after the first charge (for example, loses 20% per hour in standby mode), this may indicate: Battery defect (check in Settings). → Battery status. Background processes (go to Settings) → Battery → Battery usage and see which applications consume energy. Unoriginal firmware (on some customized ones) ROM Like LineageOS, you might have poor power optimization. The first two cases will be helped by resetting (Settings). → The phone. → Resetting. The third one is reflashing to the official MIUI.
Charging methods comparison: what is best for the battery
There are several approaches to charging smartphones, and we tested them with the Xiaomi 11T Pro (5,000 mAh battery) and measured the effect on battery wear after 6 months of use.
| Charging method | Average battery wear over 6 months | Pluses | Cons |
|---|---|---|---|
| Charge up to 100% each time | 18-22% | Maximum range | Accelerated degradation, risk of overheating |
| Charging up to 80% + rarely up to 100% | 8-12% | Minimum wear, battery lasts longer | We need to recharge more often. |
| Fast charging (67W+) up to 80%, then regular charging | 10-14% | Rapid charge recovery, moderate wear | Requires process control |
| Charging in small portions (10-20% several times a day) | 25-30% | Convenient if the phone is severely discharged | Maximum wear due to frequent cycling |
As the data shows, the best option is to charge up to 80% with a rare increase to 100% (for example, before a long trip), a method recommended by Xiaomi engineers in their official guides. If you want maximum range, use fast charging only up to 80%, and then switch to regular.
💡
Charging up to 80% instead of 100% can increase battery life by 1.5-2 times without losing usability.
Additional tips for Xiaomi owners
Besides the correct first charge, there are a few life hacks that will help keep the battery in perfect condition:
- 🔄 Calibration of the battery. 2-3 Discharge the phone before turning off, then charge it to 100% It helps to reset the charge controller errors!
- 📱 Power saving mode. Enable it at a charge level below 20% (Settings) → Battery → Power saving mode: This limits background processes and reduces battery load.
- 🔋 Battery replacement: If the capacity has fallen below 70% of the original capacity (checked by AccuBattery), contact the service center. Xiaomi uses batteries with soldered contacts, so self-replacement can damage the board.
- 🔌 Wireless charging. On models with Qi support (e.g. Xiaomi) 13) wireless 10-15% It's less efficient and heats up the phone, and you can only use it when you need it.
For models with MIUI 14, there is a hidden function called Super Power Saving, which turns off all background processes and leaves only calls and SMS. It turns on via Settings → Battery → Super Power Saving or by long pressing the battery icon in the notification panel. This can be useful in emergency situations when you need to extend the phone’s life.
