Xiaomi Redmi 4X: Why the battery is running out fast and how to fix it

Owners of the popular budget smartphone Xiaomi Redmi 4X often face the problem of rapid loss of charge. The device, which was originally pleased with excellent autonomy, over time can turn into a “brick” that requires constant recharging, which causes natural irritation, especially away from the outlet.

The reasons for this behavior of the gadget can be many: from the banal physical wear of the lithium-ion battery to software failures in the shell of MIUI. Sometimes the culprit is a specific application that “eats” the resources of the processor in the background. Understanding the nature of the problem is the first step to its successful solution.

In this article, we will take a closer look at all the possible factors that affect the autonomy of your smartphone, and we will not give you empty tips, but will look at specific technical steps that will help you resuscitate the device.

Physical wear and condition of the battery

The most obvious and common cause is the natural degradation of battery chemistry: If your Redmi 4X is a few years old, its battery life may have run out. Lithium-ion batteries are designed for a certain number of charging-discharge cycles, after which their capacity drops.

Check the current state of the battery through the engineering menu ##6485##. In the menu, find the parameters. MB_06 (state of health and MF_05 (If the status is not Good, and the capacity figures are significantly lower than the passport. 4100 The problem is that the iron is the».

⚠️ Warning: If you notice that the back cover of the smartphone is swollen or started to move away from the case, immediately stop using the device.

In the event of critical wear, no software settings will help to restore the previous indicators of autonomy, the only right solution is to physically replace the battery in an authorized service center or install a new battery yourself, if you have the appropriate skills.

Impact of display settings and MIUI interface

The screen is one of the main energy consumers in any modern smartphone. - Redmi 4X fixed IPS-A matrix that can consume a significant portion of the charge at maximum brightness, and users often forget that automatic brightness control doesn't always work correctly.

In addition, the MIUI shell offers a lot of visuals that consume the processor's resources. Transition animations, live wallpaper and a constantly active lock screen all add up to a significant power drain. By turning off the extra animation, you can significantly extend the time.

It's also recommended that you turn off the "Rise to Power" and "Pocket Mode" function if you're not using them. These sensors are constantly surveyed by the system, which creates additional load. For maximum savings, go to the settings and set the screen timeout to a minimum of 15 or 30 seconds.

Phantom processes and background applications

Often, the user has installed an app that continues to run in the background, consuming resources, such as social networks, messengers or games with poor optimization. In Android, these processes are called “wakelocks” – they prevent the processor from going into deep sleep.

To identify the culprit, go to Settings → Battery → Statistics, and here you will see a list of applications sorted by energy consumption, and if you see a program that has not been used for a long time, but it is at the top of the list, that is an alarm.

To combat this, MIUI has a Background Activity Limit feature, go to the settings of a particular application and select No Limits for important messengers only, and set tight limits for others, which will prevent them from working in the background when the screen is off.

Problems with mobile communication and modules

The weak signal of the cellular network is the hidden enemy of autonomy. When the Redmi 4X is in an unstable reception zone, the communication module starts to work at its limit, constantly trying to find the base station, which causes strong heating of the body and sharp jumps in discharge.

The same thing happens with GPS and Bluetooth, where if you're on all the time, the phone is constantly polling the satellites, and in urban areas, that might be justified, but in a static position, you better turn off the geolocation.

If you are in a place where the net is catching very poorly (like a basement or a countryside), it makes sense to temporarily turn on flight mode.This will save a charge that would otherwise be wasted trying to connect.

System Errors and the Need for Resetting

Sometimes the problem isn't the hardware, but the software failure of the file system or cache, and after a failed MIUI update or a curved application is installed, the system may not work properly, and in such cases, a complete reset helps.

Before the procedure, be sure to back up all important data as all information will be deleted.Reset will return the phone to factory status, clearing all software errors accumulated during use.

It’s also worth checking for system updates. Xiaomi engineers regularly release patches that fix power errors. Go to Settings → About phone and click on the system version icon to check for updates.

Rules of operation for extending the life of the battery

To make sure that the new battery lasts a long time, and the old one does not degrade faster than time, you need to follow certain charging rules. Lithium-ion batteries do not like extremes: deep discharge to zero and prolonged charging at 100%.

The optimal charge range for a long battery life is between 20% and 80%. Try not to leave your phone charging overnight unless you have an original charger with a smart control circuit, although the current controllers in the Redmi 4X are smart enough.

💡

Use only original cables and power supplies. Cheap counterparts from markets often lack current stabilization, leading to overheating of the battery and accelerated wear of the charge controller.

Temperature is also critical. Don't leave your smartphone in direct sunlight or in the cold. Extreme temperatures irreversibly change the chemical structure of the electrolyte, reducing the capacity forever.

Comparison of use cases

Understanding how you use your smartphone will help you identify the cause of the discharge, so one user can read text with minimal brightness, and another can play heavy games, and the consumption in these scenarios will vary significantly.

Below is a table that will help you estimate how fast your Redmi 4X should discharge in different conditions. If your performance is significantly worse, then there is a problem.

If you notice that the phone discharges faster than the specified norms even after all the settings, it may be due to a malfunction of the motherboard, for example, in the short circuit of one of the capacitors, in which case you will need professional diagnostics in the service.

⚠️ Warning: Don’t use the Play Market’s energy-saving apps to clean up your memory. On Android, they often run worse than the built-in mechanisms and consume resources themselves, constantly hanging in the background.

The main reason Redmi 4X discharges quickly 90% of the time is either physical battery wear over the years or a specific background application that can be calculated through consumption statistics.
