How to charge the smartphone Xiaomi Redmi 5

The Xiaomi Redmi 5, launched in late 2017, is still a popular device due to its balance between price and performance. However, like any electronic device, it requires proper care, especially in terms of power consumption. Many users mistakenly believe that modern gadgets do not need specific rules of operation, but this misconception can lead to rapid degradation of the chemical composition of the battery.

In this article, we will discuss how to properly charge your phone to maximize its autonomy.We will move away from the outdated stereotypes of the nickel battery and turn to the physical and chemical features of modern Li-Ion and Li-Pol batteries, which are installed in Redmi 5.

Misuse of an energy source is not just the risk of suddenly turning off your device; it is a direct route to having to replace parts expensively or buy a new machine. Let's look at the basic principles that will help keep your gadget healthy for years to come.

Lithium battery physics in Redmi 5

The power supply of the Xiaomi Redmi 5 is based on a 3300 mAh battery. Unlike older technologies, modern lithium cells do not have a “memory effect”, which means that they do not need to be discharged to zero before connecting to the grid.

The power controller built into the device monitors the voltage on each cell very closely. When you see 100% on the screen, the battery can only be physically filled by 95-98% because the system leaves a safety buffer, which is why the charge-discharge cycle in lithium batteries is considered milder in partial recharging than in full cycles from 0 to 100%.

It's important to understand that chemical reactions inside the battery continue even when the phone is turned off. High or low ambient temperatures can accelerate the degradation of materials, so storing the device in extreme conditions is more harmful than using a charger frequently.

• 🔋 Lithium batteries do not like the deep discharge below. 5-10%.
• 🔋 Complete cycle 0-100% faster wears out the cell resource than fractional charging.
• 🔋 Heat is the main enemy of the chemical stability of the battery.

⚠️ Warning: Never leave a fully discharged Redmi 5 lying idle for months. Deep self-discharge can cause voltage to drop below critical levels, after which the standard charger will stop "seeing" the battery.

The optimal charge range and the myth of 100%

It is widely believed that the device should be kept on charge until the end, but for lithium-ion cells, the most comfortable range is from 20% to 80%. Keeping the battery in a constant state of 4.2-4.35 volts (100%) creates a high internal voltage, which speeds up oxidation processes.

If you want to maximize the life of the Xiaomi Redmi 5 battery, try not to charge 100% every day. Modern controllers are able to stop current, but microscopic charging to compensate for self-discharge still occurs by maintaining high voltage. This is called "drip charging," and it is not as harmless as it seems.

On the other hand, regularly lowering the charge below 15-20% is also undesirable. In this range, the internal resistance of the battery increases dramatically, and the heat release during subsequent charging increases. The golden mean is connecting to the network when the indicator shows about 30-40%, and turning off after reaching 85-90%.

Redmi 5 owners should pay attention to the charging optimization feature if it is available in your version of MIUI firmware.The system can learn your habits and pause charging at 80%, completing the process only before you wake up.

Selection of charger and cable

The quality of the energy that goes into the smartphone directly affects the operation of the power controller. Xiaomi Redmi 5 supports fast charging technology, but only when using the appropriate accessories. Using cheap counterparts without certification can lead to unstable voltage and overheating.

The original charger has special chips that communicate with the phone to match current. Cheap Chinese power supplies often produce a pulsating current that heats the controls inside the smartphone. This is especially critical for the Redmi 5 model, as its body does not always efficiently remove heat.

Cables also play an important role: thin wires with high resistance cause voltage to drop at the input to the phone; the controller, trying to compensate for losses, can increase charging time or, conversely, operate inefficient mode; Use cables marked 2A or higher.

• ⚡ Use power supplies with an output current of at least 2A.
• ⚡ Avoid charging from USB-port of the computer, unless data transfer is required.
• ⚡ Check the cable for the presence of cavities and inflections.

⚠️ Warning: If the power supply or the bottom of the Redmi 5 smartphone becomes so hot that it is unpleasant to hold them in your hand, stop using this accessories kit immediately.

Operating temperature

Temperature is one of the most critical factors for battery life. In the Xiaomi Redmi 5, the battery is located in close proximity to the processor and screen. The cumulative heat output of these components when charged can be significant.

It is strongly recommended not to charge the phone in direct sunlight or cover it with a blanket, in such conditions, the heat has no outlet, and the temperature inside the case can exceed 45-50 degrees Celsius, at which rates irreversible destruction of the structure of the cathode and anode begins.

In winter, you should also be careful. Putting your smartphone out in the cold at high charge levels can cause a sharp drop in voltage and instant shutdown. Lithium batteries lose their ability to give current at low temperatures, and trying to charge a frozen battery can cause lithium metal (film) to fall out, leading to a short circuit.

The optimal temperature for charging the Redmi 5 is in the range of +15 to +25 degrees Celsius. If you play heavy games while charging, the smartphone can heat up to critical values, in which case the system can force the current to stop or reduce its strength to a minimum.

Calibration of the charge controller

Over time, the software may not properly display the actual battery level. You may notice that the phone goes down quickly from 20% to 5% or hangs for a long time at 100%. This does not mean that the battery has deteriorated, most likely, the calibration of the controller has gone wrong.

For the Xiaomi Redmi 5, there is a proven calibration method that helps the system re-determine the capacitance boundaries.This process does not restore physical capacity, but makes the percentage readings more accurate, allowing you to plan the use of the device more efficiently.

Calibration should be done no more than once every 3-6 months. Frequently performing full discharge cycles can do more harm than good, so use this method only when clear signs of desynchronization of the indicator.

After these steps are completed, the controller will re-write its maximum and minimum capacity data, and if the problem with the fast discharge persists, it is possible that the physical wear of the battery has reached a critical level and a replacement is required.

MIUI settings to save energy

The MIUI operating system on Redmi 5 has powerful power management tools, and by adjusting these parameters correctly, you can use the socket less often, which indirectly extends the battery life by having fewer recharge cycles.

First of all, you should look at the Battery section in the settings, and you can activate the power saving mode, which limits the background activity of applications and reduces the frequency of the processor, and for everyday tasks like messengers or reading, this does not affect comfort, but it saves significantly charge.

It's also important to monitor applications that have permission to run and run in the background. Many programs are constantly updating content or tracking geo-position even when you're not using them. Turning off the extra background process is an easy way to reduce battery load.

• 📱 Turn off keyboard vibration and unnecessary interface sounds.
• 📱 Reduce the brightness of the screen or turn on autobrightness.
• 📱 Use a dark theme for the design AMOLED-screens (although in Redmi 5) IPS, It saves the interface energy).

💡

Use Flight Mode in areas with poor signaling. If the network catches poorly, the phone increases the transmitter power, which drains the battery many times faster.

Keeping the temperature and using quality accessories is more important than keeping the percentages of charge high.
