Xiaomi Redmi 5A is one of the most popular budget smartphones of the company, released in 2017. Despite its age, the device is still actively used due to its reliability and simplicity. However, over time, many owners have a question: what charge to use for the Redmi 5A if the original lost or failed? In this article, we will analyze all the nuances – from technical characteristics to compatibility with modern adapters.
It's important to understand that not only can the wrong charger slow down the charging process, it can also damage the battery or even make your smartphone out of order. We'll analyze the original components, the alternatives, and we'll give you safety recommendations. If you want to extend the life of your Redmi 5A, this material will be useful.
Technical Charging Specifications of Xiaomi Redmi 5A
The original charger, which came bundled with the Xiaomi Redmi 5A, has the following options:
- 🔌 Type of connector: Micro-USB (not USB-C!)
- ⚡ Exit voltage: 5V
- ⚡ Maximum current: 1A (1,000 m)
- 🔋 Power: 5W (5 watts)
These options are USB 2.0 and are designed for slow but safe charging. It is important to note that the Redmi 5A does not support fast charging (Quick Charge, VOOC and other technologies), so using powerful adapters (18W, 30W and above) will not give any advantage, and in some cases can even be harmful.
The battery has a capacity of 3000 mAh, and when using the original charger, it takes about 2.5-3 hours to fully charge.If you notice that the smartphone charges longer, this may indicate battery wear or problems with the cable / adapter.
💡
If your Redmi 5A has been charging for too long (over 4 hours), try cleaning the Micro-USB connector from dust with a wooden toothpick.
Original Charging vs. Alternatives
Many users lose or break the original charger and start looking for a replacement, so let's see which options are best.
| Type of charging | Advantages | Deficiencies | Recommendation |
|---|---|---|---|
| Original (Xiaomi 5W) | ✅ Full compatibility✅ Safety for the battery | ❌ Slow charging.❌ Hard to find on sale | ⭐ Best choice. |
| Standard. USB-adapter (5V/1A) | ✅ Cheap and affordable✅ Suitable for most devices | ❌ Quality can vary.❌ Possible overheating with prolonged use | ✔️ Acceptable option |
| Adapter 5V/2A (10W) | ✅ Faster charging (if the cable is of high quality)✅ Suitable for other devices | ❌ Can reduce battery life with continuous use❌ Risk of overheating | ⚠️ Use it carefully. |
| Fast Charges (18W+) | ✅ Accelerated charging for supported devices | ❌ Redmi 5A does not support fast charging❌ Risk of damage to the power controller | ❌ Not recommended |
If you're buying an alternative charger, look at build quality and certification. Cheap Chinese unlabeled adapters can not only slow your smartphone to charge, but also cause a short circuit or even a fire, and choose proven brands like Anker, Baseus or Belkin.
Can I use charging from other smartphones?
Many users are wondering: can you charge the Redmi 5A with a different phone? The answer depends on the adapter settings. Here are the basic rules:
- ✅ Suitable: charging from Xiaomi Redmi 4A, Redmi 3S, Redmi Note 4X (same 5V/1A or 5V/2A).
- ✅ Conventionally suitable: adapters from Samsung, Huawei, Nokia with similar parameters (5V/1A or 5V/2A), But the quality of charging can deteriorate.
- ❌ Not suitable: charging from the iPhone (even if the connector is suitable, the current may be too low), as well as adapters with a voltage higher 5V.
- ❌ Dangerous: Using chargers from tablets (usually) 5V/2.4A or higher) without control – this can cause the battery to overheat.
If you decide to use a charger from another device, be sure to check its parameters. These are usually indicated on the adapter case in the format: Output: 5V ≡ 1A or 5V ≡ 2A. Also pay attention to the quality of the cable – thin and cheap wires may not withstand the declared current, which will lead to slow charging or even damage to the port.
What happens when you use 5V/2.4A?
How to charge Xiaomi Redmi 5A: tips for extending the life of the battery
Even with the right charger, the Redmi 5A battery degrades over time, but there are a few rules to help extend its lifespan as much as possible:
- Avoid full discharge. The optimal charge range is 20 to 80 percent. Constant discharges to 0% reduce battery life.
- Don’t leave it on overnight charging. Once it reaches 100%, the smartphone continues to be recharged with microcurrents, which accelerates wear and tear.
- Use an original or certified cable. Cheap cables can cause power surges.
- Charge at room temperature. Extreme temperatures (below 0°C or above 40°C) are harmful to lithium-ion batteries.
- Turn off power-intensive functions while charging. Games, video and navigation heat up your smartphone, which negatively affects the battery.
Important fact: Xiaomi Redmi 5A does not have built-in protection against overheating when charging, so when using powerful adapters (for example, 5V/2A) the body temperature can rise to 45-50 ° C. This is critical for battery durability!
✔️ Check the cable for damage.
✔️ Make sure the Micro-USB connector is clean.
✔️ Check the temperature of your smartphone (does not have to be hot)
✔️ Use a grounded socket (if the adapter supports it)-->
Frequent charging problems and their solutions
If your Redmi 5A has stopped charging or is doing it too slowly, the reasons may be different.
⚠️ Attention! If the smartphone does not respond to charging at all (no indication, does not turn on), do not try to disassemble it yourself. This may lead to loss of warranty or damage to the board.
| Problem. | Possible cause | Decision |
|---|---|---|
| Charging is going very slowly. | ❌ The cable is damaged.❌ A low-current adapter is used (0.5A) | 🔧 Replace the cable with original or certified cable🔧 Use the adapter. 5V/1A or 5V/2A |
| The smartphone is charged only when turned off. | ❌ Failed power controller❌ Micro-USB connector damaged | 🔧 Check the connector for dirt or damage.🔧 Contact the service for diagnosis |
| The charge is interrupted (it comes, it does not). | ❌ Bad contact in the connector❌ Unstable voltage in the network | 🔧 Move the cable in the connector (if it helps - replace the connector)🔧 Connect through the network filter |
| The smartphone warms up when charging | ❌ It uses an adapter that is too powerful.❌ Charging occurs at high load (games, video) | 🔧 Go to the adapter. 5V/1A🔧 Close all applications before charging |
If none of these things work, the problem may be battery wear, the average life of a lithium-ion battery is 2-3 years, or 500-800 charge cycles, and then the capacity drops markedly, and the smartphone starts to run out faster, in which case the only solution is to replace the battery at the service center.
How to choose a cable for Xiaomi Redmi 5A
Often the problem is not with the adapter, but with the Micro-USB cable. Cheap wires wear out quickly, lose contact, or even melt.
- 🔍 Wire thickness: quality cables have a diameter of at least 3-4 mm (thin wires warm and break quickly).
- 🛡️ Availability of protection: good cables have reinforced connectors with a metal body and protection from inflections.
- 🔌 Certification: Look for labeling USB 2.0 and logos USB-IF (This ensures compliance with the standards).
- 📦 Manufacturer: give preference to proven brands: Xiaomi, Anker, UGREEN, Baseus.
Xiaomi’s original cable is 1 meter long and black with red inserts. If you buy a replacement, try to choose a cable of the same length – too long wires (more than 1.5 m) can lose some power, which will slow down charging.
💡
Never use cables with damaged insulation or bare wires, which can short-circuit and cause the charger to fail.
Safety in Charging: What Not to Do
Many users neglect safety regulations, leading to breakdowns or even dangerous situations.This is what you should not do when charging the Xiaomi Redmi 5A:
⚠️ If you notice that the adapter or cable is heated to a temperature at which it is impossible to hold them in your hands, immediately turn off the charging.
- 🔥 Charge your smartphone under direct sunlight or near heat sources (battery, radiator, stove).
- 🚫 Use damaged or "handicraft" adapters (e.g., with or without an open board).
- 💦 Charge in wet conditions (bathroom, kitchen next to sink).
- 🔌 Connect to unstable power sources (e.g. generators or inverters without voltage stabilization).
- 📵 Use your smartphone during a thunderstorm if it is connected to a power outlet (risk of damage from a power surge).
It is also not recommended to use wireless chargers for the Redmi 5A. This smartphone does not support Qi technology, and attempts to connect it to wireless charging can cause internal components to overheat or damage.
