Owners of the legendary Xiaomi Redmi 4 smartphone often face the natural aging of a lithium polymer battery, which eventually loses its capacity. If your device starts to run out in a couple of hours, spontaneously turn off at 20-30% charge or long charge, these are sure signs that the cell life is exhausted, in this situation, the user is faced with the question of the feasibility and cost of replacing the battery.
The mobile parts market is now full of offers, and finding the right battery is easy, but the price range can vary greatly, depending on whether you choose an original part or a budget counterpart, and whether you plan to install yourself or contact a service center. Understanding the pricing structure will help save and avoid buying a low-quality product.
In this article, we will analyze in detail the current battery prices for Xiaomi Redmi 4, analyze the difference between the Prime and Standard models, and assess the economic feasibility of repairs. You will learn what the total amount is made of and what to look for when choosing components to extend the life of the gadget for another couple of years.
Factors Affecting Battery Cost
The first thing that determines the price is the origin of the part. Original batteries, made to order Xiaomi, always cost more, as they pass strict quality control and have a declared capacity of 4100 mAh. Market copies, often called "replicas" or "high copy", can cost two to three times less, but their real capacity often does not match the stated, and the life is limited.
The second important factor is the smartphone model, as the Xiaomi Redmi 4 came in two main versions: the regular version and the Prime version. Despite the appearance of similarities, the batteries can differ in the plume connector or dimensions, which affects the availability and price of a particular spare part in stores.
Buying a part from a large electronics store in your city will cost more than ordering from Chinese marketplaces, but in the second case you risk getting married or waiting for delivery for several weeks.
- 🔋 Battery type: original vs. quality copy or cheap counterpart
- 📱 Compatibility: Differences between Redmi 4 Standard and Prime
- 🛠 Package: Purchase only a cell or module assembled with a frame
- 🚚 Logistics: delivery cost when ordering from abroad or markup of a local store
The price is also affected by the presence of protective controllers and markings. QR-Cheap analogues often lack these security features, making them attractive for the price but risky to use.
Average prices in the spare parts market
Analyzing current offers in stores and service centers, you can distinguish several price ranges: the budget segment is represented by batteries of unknown Chinese brands, the cost of which varies between 300-500 rubles. Such batteries often have a real capacity of about 2000 mAh, despite the labeling of 4100 mAh, and serve for a short time.
The mid-range, which is most popular with users, offers batteries for 600-900 rubles. Here you can find quality copies with honest capacity or restored originals. It is in this range that the middle ground between price and service life of the device is most often found.
Original new batteries or high-end OEMs (Original Equipment Manufacturer) cost between 1,000 and 1,500 rubles or more, and you pay to make sure that the chemical composition meets safety standards and the charge controller will work correctly with the firmware of your smartphone.
| Category | Price (rupe) | Capacity (real) | Guarantee |
|---|---|---|---|
| Budgetary analogue | 300 - 500 | ~2,000 mAh | 14 days |
| Quality copy | 600 - 900 | ~3500 mAh | 1-3 months |
| Original/OEM | 1000 - 1500+ | 4100mAh | 6-12 months |
Prices can fluctuate depending on currency rates and seasons. Always check the date of production before buying: a battery that has been in storage for more than two years has already lost some of its capacity, even if it is new.
How to distinguish the original by appearance?
Cost of replacement work in the service
If you don’t have the skills to repair electronics or are afraid of damaging plumes, it is wise to contact a specialized service. The cost of replacing the service consists of the cost of the battery itself and the work of the master. On average, the work of a battery replacement specialist in Xiaomi Redmi 4 costs from 500 to 1000 rubles, depending on the region and level of service.
It's important to understand that this amount often includes not only a physical replacement, but also a diagnostic of the device. The wizard will check the charging connector, the power controller and the status of the board to make sure that the problem lies in the battery. Sometimes rapid discharge is caused by a software failure or a circuit, and replacing the battery will not help.
Official service centers may charge more for work, but they provide a formal guarantee for work done and the part installed. Private workshops offer lower prices, but the quality of parts and skills of craftsmen can vary greatly. Always require a check and a warranty card.
💡
When you contact the service, be sure to ask for your old battery back, which will help you visually compare it to the new one and make sure that the replacement has actually been made.
Also, if you open the case and damage the screen or back cover (which often happens when the glue is not properly heated), you will have to pay for these parts, so choosing a proven wizard with good reviews saves money in the long run.
Self-Replacement: Savings or Risks?
Replacing the battery with your own hands saves the cost of the master’s work, but requires a minimum set of tools and accuracy. For the Xiaomi Redmi 4, you will need: a hair dryer or heating platform for softening the glue, a sucker, thin plastic blades (mediators), a cross screwdriver and tweezers.
The process starts by heating the back cover, and the glue that holds it down melts at a temperature around the back. 80-90 After heating, you need to gently lift the lid with a suction cup and insert the mediator around the perimeter, separate it from the body, and the key here is not to damage the plume of the fingerprint scanner, which is often glued to the lid.
Then you unscrew the screws that lock the protective plastic bar and turn off the battery plume. The old battery is usually glued to double-sided tape, so it needs to be carefully tweaked and removed. The new battery is installed in reverse order, with a new layer of glue or B-7000 applied to fix the lid.
☑️ Replacement tools
⚠️ Warning: Never try to remove a bloated battery by stabbing it with a needle or knife! This can cause lithium to ignite and cause chemical burns. If the battery is swollen, remove it as carefully as possible, avoiding mechanical damage to the body.
If you've never taken a smartphone apart, check out the tutorials for your model. Redmi 4 has its own nuances, like plume location and layout density, that you need to consider to avoid making things worse.
Redmi 4 and Redmi 4 Prime models
When looking for a spare part, it is critical to know the exact modification of your device.The Redmi 4 Prime model was equipped with a more powerful Snapdragon 435 processor and had a 4100 mAh battery. The regular version of the Redmi 4 (Standard) often came with a Snapdragon 430 processor and could have a slightly different battery design, although the capacity also claimed at 4100 mAh.
The difference may be the location of the contact group and the length of the plume. If you buy a battery from the Prime version for a regular Redmi 4 (or vice versa), the plume may not reach the socket on the board or, conversely, will be too long, leading to inflection and short circuit.
To find out the model, go to the phone settings, select About phone and look at the model number, and you can find information on the sticker under the back cover (if it's still readable) or on the box from the device, buying a "universal" battery without specifying the model is a lottery.
- 🔍 Check the model number in the settings before buying
- 🔌 Compare the length of the plume of the old and new battery
- 📏 Make sure the size of the body matches
Visually compare the connection socket. Some battery batches may have a misaligned connector or a different shape, and it's best to take your old battery with you to the store for comparison, or to carefully study the photos of the product when you order online.
💡
Knowing your smartphone model (Prime or Standard) is a key factor in successful purchase of a compatible battery.
