Owning a Xiaomi Redmi 5 smartphone often raises questions about choosing the right network adapter. Many owners lose the original power supply or simply want to buy a second office kit so they don't carry it around. Understanding exactly what kind of charging your device requires is critical to ensuring that the battery is running smoothly.
This budget bestseller, which came out a few years ago, is still in use today because of its reliability. However, like any lithium polymer battery, the battery in Redmi 5 degrades over time. A properly selected charger can slightly extend the life cycle of the energy storage device, while using substandard analogues can kill it in a couple of months.
In this article, we will discuss in detail the technical characteristics of the standard adapter, consider the support for fast charging technologies and answer the question whether it is possible to use more powerful blocks without harming the smartphone. 10 Watt (5V/2A), and whether to overpay for more expensive solutions.
Technical characteristics of the staff adapter
The standard Xiaomi Redmi 5 package included a power supply that was considered a good solution for the budget segment at the time of its release. It did not have extreme speeds, but provided a safe and stable current for the 3300 mAh battery.
The original adapter runs in standard 5 volts 2 Amps. It's a classic circuit that doesn't require complex communication between the phone and the power supply to start the process. If you use a good quality cable, the phone will charge at exactly the rate that it takes about 2.5 to 3 hours to complete the cycle.
It is important to note that the connection connector in the smartphone is Micro-USB. Despite the ubiquity of Type-C in more modern models, the "five" remained true to the old standard. This imposes restrictions on the maximum bandwidth of the cable, so the use of thick cords with support for high currents here does not make technical sense.
⚠️ Warning: Do not attempt to use Type-C cables with Micro-USB adapters from dubious manufacturers. Mismatching the pins may short-circuit or damage the power controller on the motherboard.
The original unit is designed to be protected against overheating and surges. Cheap Chinese counterparts, which are often sold in markets, may not have such fuses, and as a result, when you jump on the network, not only the block will burn, but also the inside of your Redmi 5.
Why is the power supply warming up?
Xiaomi’s original adapter can heat up while running. This is a normal physical energy conversion process. However, if the body temperature becomes scorching, this may indicate poor contact in the outlet or a malfunction of the unit itself.> Support for Quick Charge technology is a key issue to support accelerated charging technologies. Xiaomi Redmi 5 is based on a Qualcomm Snapdragon 450 processor. This platform historically supports Quick Charge 3.0 technology. However, the implementation of this function depends not only on the chipset, but also on the manufacturer’s decision. Unlike flagship lines, one of fast charging technologies. Xiaomi often has more software-ened models, even if the input is more "limitted". In the case of Redmi 5, The device is capable of recognizing protocols QC, But the charging speed rarely exceeds standard rates because of the limitations of the battery controller. QC 3.0 The Quick Charge-enabled unit can dynamically change voltage" 5 Volt, adapter will give 5 It's compatible with all devices, and the main advantage of this approach is that it has a good element base inside the power supply itself, which makes it more stable. 3.0 If you're planning on using it for other gadgets, yes, absolutely. Unless you're using it for Redmi. 5 — Significant difference in charging time compared to a conventional unit 5V/2And you probably won't notice. The accessories market is full of offers, and choosing a quality product becomes more difficult. Let's compare the original product from Xiaomi with typical representatives of the budget segment and premium counterparts of other brands. Original Xiaomi Cheap Analogue (NoName) Premium (Anker/Baseus) Stability of voltage High Low (jumps) Very high efficiency (heating) Medium Low (heated) High service life 2-3 year-end 3-6 months 3-5 As you can see from the table, overpaying for a brand in the case of chargers is an investment in security. Cheap blocks often do not keep the declared ones. 2 Ampere, giving out real ones 1.2–1.5 And that's a lot more charging time, and in addition, the current pulsations in these units can cause problems with the touchscreen when you're connected to the grid. Premium third-party brands like Anker or Baseus often offer even better specs than Xiaomi's stock adapter.They're smaller, less warm and have a more robust build. For the owner of Redmi 5, buying such an adapter will be a great upgrade, especially if the original failed. ⚠️ Warning: If the screen starts to react randomly to touch when you connect your phone to charge (touch walks), stop using this adapter immediately, which is a sign of high current pulsations that are dangerous for the display controller. The effect of charging on battery life is the most vulnerable element of the smartphone. Redmi 5 has a 3300 mAh non-removable cell. Chemical processes inside it are irreversible, but the speed of their flow depends on the operating conditions. Charging with improper current is one of the main enemies of longevity. Using too powerful adapters (for example, from a laptop or tablet with current) 3And above, it's theoretically safe, because the phone will take as much as it needs, but in practice, old power controllers in public sector workers can not properly work handshake protocol, starting to warm up, overheating is a major factor in lithium degradation. The optimal mode for extending the life of the battery is considered to be charging 1And (5V/1Ah, but it's going to take a very long time. 2Also harmful cycles of full discharge to zero and charge to 100% And then you hold it on the wire, and modern controllers cut the current, but there's still a small power current, if you notice that the phone started charging before it could be charged. 80% and stop, or vice versa, quickly sit down after 90%, The problem may not be in charging, but in calibrating the battery controller. In such cases, full discharge before shutdown and subsequent charge of the device turned off to 100% helps. Problems and their solution owners Redmi 5 often face typical charging problems. The most common is the inscription "Plug the charger" with the plugged cable. This may indicate wear on the Micro-USB connector, which is horizontal and subject to mechanical stress in this model. Another common problem is slow charging. If the phone used to charge in 2.5 hours, and now it takes 5 hours, check the cable. Thin and long cables have high resistance, which eats up some of the current. Replacing the cable with short and thick often solves the problem without buying a new unit. MIUI sometimes incorrectly displays the percentage of charge or hangs at the stage of the logo when connecting the power. In such cases, it helps to reset the settings or, in rare cases, flashing the device. ☑️ Diagnostic Charging Problems Check the cable on another device>Clean the charging port from dust (dental cleaning)>Reboot your smartphone>Try another power supply unit>Measure the voltage with a multimeter (for advanced: 0 / 1 FAQ: Frequently Asked Questions: Can I Charge Xiaomi Redmi? 5 So, you can use a Samsung unit with Fast Charge technology, yes, you can. Protocols are compatible. The phone will take a safe current, usually. 5V/2Oh, and it'll charge normally. The unit won't burn and the phone won't suffer. Why does the phone only charge when it's off? It's probably a software conflict or a worn-out connector. When the phone is off, the current requirements are lower, and the contact can pass. Try cleaning the port or replacing the cable.How long does the Redmi normally charge? 5? With a serviceable original unit (5V/2A) and cable up to 1 meter long, a full cycle from 0 to 100% takes from 2 hours 30 minutes to 3 hours. Is it harmful to leave the phone on charging all night? For modern smartphones, this is not critical, the controller turns off the current. However, to maximize battery life, it is better not to keep the device 100% long. It is better to charge during the day or use smart sockets. Which cable is better to buy for replacement? Look for cables marked with "2A" or "3A" lengths not more than 1.5 meters. Preferritess (existential filters) at the end of the interference.
