Xiaomi Redmi 5 Plus is one of the most popular smartphones in the budget segment, released in 2018. Despite its age, the device is still actively used due to balanced performance and reliability. However, owners often wonder: which charging connector supports this model, and which cables or adapters can be used without risk to the battery?
In this article, we will discuss in detail the type of Redmi 5 Plus connector, its technical features, compatibility with modern charging standards, as well as give recommendations for choosing accessories. You will learn whether you can use USB-C instead of the original cable, how to avoid port damage and what to do if the smartphone stopped charging.
If you’re planning to buy a new cable or adapter, or just want to extend the life of the connector, this information will be helpful. We’ll also look at typical charging issues and how to fix them to keep your Redmi 5 Plus running smoothly.
Technical characteristics of the charging connector Xiaomi Redmi 5 Plus
Xiaomi Redmi 5 Plus features a classic Micro-USB Type-B connector, a standard that was common before the mass transition to USB Type-C. This port supports:
- 🔌 Transfer of data by protocol USB 2.0 (speed up to 480 Mbps).
- ⚡ Maximum current charge to 2A (When using the original adapter).
- 🔄 Backward compatibility with most cables and chargers of the time.
Importantly, the Redmi 5 Plus doesn’t support modern fast charging standards like Quick Charge or Power Delivery.The maximum charging power is limited to 10W (5V/2A), which is the baseline for 2018 devices.This means that even if you plug your smartphone into a Quick Charge 3.0-enabled adapter, the charging speed won’t increase – the device will only consume the allowable 10W.
The Micro-USB connector in the Redmi 5 Plus has a standard pin location, but some users note its fragility with frequent connections. This is due to the design of the port: thin metal "tongues" inside the connector wear out over time, which can lead to poor contact or breakage. To prolong the life of the cable, it is recommended to use high-quality cables with reinforced connectors.
Compatibility with cables and adapters: what can you use?
One of the most common questions owners Redmi 5 Plus: can you charge your smartphone with a USB Type-C cable or an adapter from another Xiaomi model?
Cables:
- ✅ Micro-USB → USB-A: original cable from the kit or any certified analogue (e.g. from Samsung, Sony).
- ❌ USB Type-C → USB-A: It's not physically possible to connect such a cable to the Redmi 5 Plus.
- ⚠️ Micro-USB → USB-C: adapters exist, but they can reduce the charging speed and increase the risk of overheating.
Adapters (charging devices):
- ✅ 5V/2A: Original adapter from Xiaomi or analogues from other brands (for example, Anker, Baseus).
- ⚠️ 9V/2A (Quick Charge: the smartphone will charge, but only at the base speed (5V/2A). Fast charging is not activated.
- ❌ Unnamed adapters with declared power >10W: risk of overheating or battery damage.
If you have lost the original cable or adapter, it is better to choose certified accessories labeled MFi (for Apple-compatible devices) or USB-IF (universal standard). From budget options, UGREEN and Aukey cables have proven themselves well - they have reinforced connectors and support the declared currents.
💡
Before buying a new cable, check it for metal shielding – this reduces the risk of interference with data transmission and increases the service life.
Can I use wireless charging for the Redmi 5 Plus?
Xiaomi Redmi 5 Plus does not support wireless charging at the hardware level, lacks the induction charging coil needed to work with Qi-compatible stations, but some users are trying to get around this limitation by:
Ways to “add” wireless charging (and their risks):
- 🔌 Adapters-pins: attached to the Micro-USB connector and allow you to place the smartphone on the charging station. ⚠️ Warning: these adapters often overheat and can damage the charging port, and they block access to the connector, which is inconvenient when used actively.
- 🛠️ Self-installation of the module: requires dismantling of the smartphone and soldering, the risk of damage to the board or battery is extremely high, and the result is not guaranteed.
- 📱 Battery cases: Some models have built-in battery and support wireless charging, but it is more of an alternative to power bank than a full replacement for the original connector.
If you really need wireless charging, it’s wiser to consider buying a new smartphone with Qi support (like the Xiaomi Redmi Note 10 or later).
Why are manufacturers abandoning micro-USB?
Typical Charging Connector Problems and Their Solutions
Over time, the Micro-USB connector in the Redmi 5 Plus may start to work unstable.
| Problem. | Possible cause | Decision |
|---|---|---|
| The smartphone is not charging | Connector contamination, cable damage | Clean the port with alcohol, check the cable on another device |
| Charging is going very slowly. | Use of a non-original low power adapter | Replace the adapter with 5V/2A, check the cable for damage |
| The smartphone charges only in a certain position | Wear of connector contacts | Carefully bending contacts or replacing the connector in the service |
| The device heats up when charging | High power adapter (>10W) | Switch to the original adapter, avoid using while charging |
If the cable and adapter are checked, the battery or power controller may be faulty, and if you try to repair yourself without experience, you may short-circuit or fail the device completely.
To prevent problems with the connector:
Use only original or certified cables|Avoid sudden movements when connecting/offline|Regularly clean the port of dust and debris|Do not charge your smartphone in high humidity conditions-->
How to speed up the charging of Redmi 5 Plus: myths and reality
Many users are looking for ways to speed up the Redmi 5 Plus charging, especially if the battery is running out quickly, but due to hardware limitations, the options are extremely limited.
Myths:
- ❌ "Enabling flight mode speeds up charging": in practice the difference is 5-10 It's a little bit of a full cycle.
- ❌ "Using Quick Charge 3.0 adapter will double the speed: the smartphone simply does not support the protocol, so the power will remain at the same level 10W.
- ❌ "Charging with the screen off faster: energy savings are minimal, and the difference in charging time is no more 10-15%.
The real way (slight acceleration):
- ✅ Use the original adapter: non-original chargers often give less current.
- ✅ Disable background processes: Close unused applications through Settings → Annexes.
- ✅ Charge at room temperature: At low or high temperatures, the battery charges more slowly.
The most effective way to speed up charging is to monitor the battery status: if its capacity has fallen below 70% of the original, the charging time can increase by 30-50%, in which case it is worth considering replacing the battery (the original ARB4190 for the Redmi 5 Plus costs about 1000-1500 rubles).
💡
No life hack will overcome the hardware limitations of the Redmi 5 Plus. The maximum charging speed is 10W, and this cannot be changed software.
How to replace the Micro-USB connector with the Redmi 5 Plus?
If the charging connector on your Redmi 5 Plus fails, you have two options:
1. Repair or replacement of the connector
- 🔧 Self-replacement: requires soldering and experience with electronics. The cost of a new connector - from 200 rubles, but the risk of damage to the fee is high.
- 🛠️ Contact the service: the price of work — 800-1500 It is recommended to choose services with a guarantee.
2. Alternative charging methods
- 🔋 Use of a dock with contacts: some models connect to pins on the board without passing the connector.
- 🔌 Wireless power bank with cable: you can connect an external battery directly to the battery contacts (requires modifications).
⚠️ Note: When replacing the connector, only use original parts or quality analogues (e.g. from Huawei or Samsung). Cheap Chinese connectors often have poor contact and break quickly.
If you decide to replace the connector in the service, check whether there is a warranty for work. Also check whether the master damaged the waterproofing gasket (if any) - this can lead to moisture entering the device.
Redmi 5 Plus comparison with other Xiaomi models by connector type
