How to remove fast charging on Xiaomi Poco X3: all the ways and risks

Xiaomi Poco X3 is a popular smartphone with support for fast charging 33W, but not all users want to use this feature.Some people want to extend the battery life, someone faces overheating, and someone just does not like how quickly the battery drains after intensive use of “turbo” mode. In this article, we will analyze all the working ways to turn off fast charging, including hidden settings, analyze the pros and cons of this solution, and give recommendations on alternative methods of caring for the battery.

It's important to understand that the manufacturer doesn't always provide a direct switch to deactivate fast charging in standard settings. So some of the methods will require working with an engineering menu or third-party utilities. We'll describe each step in detail so that even a beginner can cope without risking damage to the device. If you doubt your abilities, you better contact a service center or use safe alternatives (which we will also discuss below).

Why do users want to turn off fast charging?

At first glance, fast charging seems like a definite plus: in 30-40 minutes, the battery charges up to 70-80%. However, this mode has a downside that forces Poco X3 owners to look for ways to deactivate it.

• 🔋 Battery degradation: Lithium-ion batteries wear out faster at high charge currents. Research suggests that using fast charging can reduce battery life by 15-20% in 2-3 years.
• 🔥 Overheating of the device. When you charge intensively, the processor and battery heat up to 40-45.°C, which is not only uncomfortable for the hands, but also potentially dangerous for internal components.
• ⚡ In regions with frequent power surges, fast charging can cause failures or even damage to the power controller.
• 💰 Savings on chargers: Original Quick Charge power supplies cost more than standard ones, and their loss or breakdown forces users to look for alternatives.

In addition, some owners note that after using fast charging, the smartphone begins to discharge faster in everyday scenarios, this is due to the fact that the power controller adapts to high currents, and conventional charging (for example, from a power bank) can be perceived as “insufficient”, which leads to suboptimal power distribution.

Method 1: Disconnect via standard settings (if available)

Some versions of MIUI for the Poco X3 have a built-in charging power limit option, but it depends on the regional firmware and the MIUI version.

1. Open the Settings app.
2. Go to the Battery and Performance section.
3. Select Battery Settings → Charging.
4. Look for Limit Charging or Slow Charging Mode.

If you don't have that option, don't worry: 80 percent of the time, it's not available in global firmware, and you'll have to use alternative methods, as described below.

💡

If your firmware doesn't have a charging restriction option, try upgrading MIUI to the latest version. Sometimes the manufacturer adds new features to fresh builds.

Method 2: Use of an engineering menu (for power users)

The Engineering Menu is a hidden settings section where you can change the hardware settings, including the charging controller. Attention: wrong actions here can cause the device to malfunction or even fail. If you're not sure what you're doing, skip this method.

To get into the engineering menu on Poco X3:

1. Open the Phone app.
2. Enter the combination: ##4636###.
3. In the menu that opens, select Battery Information.
4. Look for options related to AC Charge or USB Charge.

Some firmwares can set the current limit (for example, up to 1000 mA instead of the standard 2000-3000 mA for fast charging). However, the interface of the engineering menu may differ - if you do not have the right items, try another method.

Method 3: Forced restriction through charger

If the software methods didn't work or seemed too risky, we could go another way, which is to limit the charging power at the power supply level.

• 🔌 Standard chargers (5W/10W). Use a power supply from older smartphones (for example, from iPhone) 5 or Samsung Galaxy S3). They give off current. 1Oh, what's in? 3–4 Time slower than the original Poco charger X3.
• 🔋 Some external batteries (e.g. Xiaomi Mi Power Bank 3) have a low current mode for gentle charging.
• 📱 USB-port of computer or laptop. USB 2.0 is not more than 500 mA, and USB 3.0 – up to 900 mA, which is well below the standard 33W.

The downside of this method is that charging will take 2-3 times longer, for example, a full cycle from 0% to 100% can take 4-5 hours instead of the usual 1.5-2 hours, but the battery will heat up much less and its life will last longer.

Use the original cable (not cheap analogues)|Charge at a temperature of 10–30°C|Do not allow a grade below 20%|Turn off charging after 80-90% (if possible)-->

Method 4: Applications for charging control (root required)

If you're ready to root your Poco X3, you can use specialized utilities to fine-tune your charging options, including:

• 📱 AccuBattery (free version with restrictions) Shows the current charging current and allows you to set notifications when you reach a certain level (for example, 80%).
• ⚡ Battery Charge Limit (requires root) Allows software to limit the maximum charging current to 1000-1500 mA.
• 🔧 Kernel Adiutor (power users) gives access to the core of the system where you can change the parameters of the power controller.

Warning: Getting root rights voids the warranty and can cause the device to run unstable, and incorrect settings in these applications can cause the battery to fail, and only use this method if you are confident in your actions.

💡

Root access gives you maximum control over charging, but the risks outweigh the benefits for most users, and we recommend that you try out secure charging methods (from USB or power bank) first.

What happens if you turn off fast charging: pros and cons

The decision to turn off fast charging is always a trade-off between convenience and durability, so let's look at what to expect once you deactivate this mode.

It’s also important to consider the psychological factor: users who are used to fast charging often feel uncomfortable with long waits. If you are often on the road or use your smartphone as a navigator, turning off Quick Charge can be uncomfortable, in which case it is worth considering a hybrid approach: use fast charging only in critical situations, and in everyday life – careful methods.

Alternative ways to extend battery life without turning off fast charging

If you don’t want to sacrifice charging speed but are worried about the battery status, use these tips:

• 🔄 Avoid full discharge and 100% charging. Optimal range is 20-80%. Modern Xiaomi smartphones support Optimized Charging (in battery settings), which automatically stops charging by 80%.
• ☀️ Do not charge in the heat or cold. The ideal temperature for charging is 10–30°C. Heated battery degrades 2-3 times faster.
• 📵 Turn off unnecessary features while charging. Wi-Fi, Bluetooth, GPS And the background apps increase the heat. Use the In-plane mode if you don't need a smartphone urgently.
• 🔌 Use original accessories. Cheap cables and power supplies can produce unstable voltages, which accelerates battery wear.

Another effective method is battery calibration. Every 2-3 months, fully discharge the smartphone before turning it off, and then charge to 100% without interruption. This helps the controller to more accurately determine the real charge level. For the Poco X3, it is also useful to reset battery statistics in the settings (Settings → Battery → Three dots in the upper right corner → Reset battery statistics).

💡

If your Poco X3 is running out quickly, check the list of apps in the Battery → Battery section. Often the culprits are messengers (such as Telegram or WhatsApp) with active synchronization in the background.
