Owners of the popular Xiaomi Redmi Note 8 Pro often face natural wear and tear after 2-3 years of active use. The question of how much a new battery costs becomes critical when battery life is reduced to several hours and the device begins to turn off in the cold. The market offers a wide range of solutions, from cheap copies to expensive original components, and the price range here can reach several thousand rubles.
Understanding the real cost of components will help avoid buying a substandard product that could damage a power controller or even a motherboard, and in this article we will discuss the pricing of batteries for this model, analyze the cost of a professional replacement in service centers, and give recommendations for self-installation.
It is important to remember that the cost of the battery is not the only item of expenditure if you are planning a replacement in the workshop. The total amount often includes the work of a craftsman, the use of a professional tool and consumables such as adhesives and sealants. Next, we will consider all aspects of pricing for this critical component of the smartphone.
Factors Affecting the Price of Battery
The cost of a battery for the Redmi Note 8 Pro depends on its origin and capacity. The model is equipped with a 4500 mAh battery, and to maintain the declared characteristics it is important to use quality cells. Cheap counterparts often have real capacity 20-30% below the declared, which negates the economic sense of such a purchase.
Original components, supplied under the Xiaomi brand, undergo strict quality control and have built-in protection against overheating and overdischarge. BMS-A high-quality Battery Management System often determines the price difference between the original and the budget copy. Cheap versions may not have proper calibration, which will lead to incorrect display of the percentage of charge in the system.
The price is also affected by the type of packaging: batteries that come in technical packaging (bulk) are cheaper than those sold in retail boxes with cables and instructions, but for the end user, the state of the cell itself is more important: no signs of bloating, scratches on contacts and the date of production.
How to check the date of production of the battery?
When choosing a warranty, you should pay attention to the seller's warranty. Stores that are confident in their goods provide a warranty of 3 to 6 months, which is an indirect indicator of quality. Buying without warranty is always the risk of getting a marriage or a used product.
Average prices in the market: original and analogues
Analysis of the offers in the Russian market of electronics and parts allows you to distinguish several price segments: the price of the battery for the Redmi Note 8 Pro varies depending on the sales channel and the status of the seller.
| Type of battery | Capacity | Average price (ruble) | Guarantee |
|---|---|---|---|
| Original (Service Pack) | 4500mAh | 1800 - 2500 | 12 months |
| Quality analogue (Nohon, Deji) | 4500mAh | 900 - 1400 | 6 months |
| Budget copy (OEM) | 4500mAh (stated) | 400 - 700 | 14 days |
| Refurbished (Refurbished) | 4500mAh | 600 - 900 | 3 months |
It is worth noting that prices at official service centers may be higher than those shown in the table, as they include brand overhead and the cost of qualified service.
💡
The best choice for price/quality ratio is branded counterparts from well-known spare parts manufacturers such as Nohon or Deji, which often outperform budget originals in terms of charge cycle life.
Budget copies that cost less than 500 rubles are often a lottery, and you can get a soldered old battery or a new cell of low grade, the savings are questionable, since you will have to change the battery again in six months.
Cost of replacement at the service center
If you don’t have the skills to repair electronics, replacing the battery in the service center will be the safest option.The cost of the service is the cost of the battery itself and the work of the master. On average, the work to replace the battery in the Xiaomi Redmi Note 8 Pro costs from 800 to 1500 rubles, depending on the region and level of service.
The challenge with this model is that the back cover is glued around the perimeter, requires heating and special suction cups and mediators, and unprofessional intervention can damage the plumes of the display or fingerprint scanner, which can entail costly repairs.
- 🔧 The standard replacement procedure takes from 30 to 60 minutes depending on the queue and the workload of the masters.
- 🧪 Many services offer free diagnostics before work begins, which allows you to accurately determine the status of the battery.
- 📜 Be sure to demand the issuance of a check or an act of work performed with an indication of the replaced detail.
Some workshops offer a service "replace your battery", but in this case they can absolve themselves of responsibility for the quality of the part, it is better to purchase the battery directly from the contractor, so that in case of problems there is no dispute about the fault.
Self-replacement: risks and savings
For those who are saving on a handyman's job, self-replacement is an attractive option: if you buy a battery separately, you only pay for the parts, but you have to consider the cost of the tools if you don't have them.
To successfully replace, you will need: a dryer (or heating pad) for heating the glue, a sucker, a set of screwdrivers (cross and star), a plastic spatula and a special glue B-7000 or double-sided tape to fix the lid. The total budget for tools can be from 1000 to 2000 rubles, which, when used once, makes self-repair less profitable.
⚠️ Warning: Before starting any work, be sure to completely turn off the smartphone. Attempting to disconnect the battery plume when the device is on can lead to a short circuit and failure of the power controller.
The process requires care when working with the main module plume, which often runs over the battery, damage to this plume will cause the phone to malfunction, and it is also important to properly connect the battery connector to the board, making sure that the contacts fit tightly.
☑️ What you need for a self-replacement
How to prolong the life of a new battery
Once a new battery is installed, it is important to operate it properly so that it lasts the manufacturer’s stated lifespan. Modern lithium polymer batteries do not have a “memory effect”, but are sensitive to extreme states of charge.
Try to keep the device from running out to zero and shutting down. The optimal range for a long battery life is between 20% and 80-90%. Although modern smartphones have controllers that prevent overcharging, prolonged charging at 100% can contribute to the degradation of the cell chemistry.
Temperature is also critical. Don't leave the Redmi Note 8 Pro in direct sunlight or on the dashboard of the car in the heat.High temperatures are the main enemy of lithium batteries, causing irreversible chemical changes.
💡
Use the original charger or certified Quick Charge-enabled counterparts. Cheap power supplies can give off unstable voltages, which harm the charge controller.
Frequent problems after battery replacement
Sometimes, after installing a new battery, users face unexpected difficulties, the system may incorrectly display the percentage of charge, showing jumps from 40% to 10% or vice versa, this requires calibration of the battery, which can be done software.
Another common problem is the message "Non-original battery" or constant temperature notifications, which occurs if the battery controller has not been reset or the battery itself does not have a chip compatible with MIUI firmware.
- 📉 A quick standby discharge may indicate a software failure or background processes, rather than a battery defect.
- 🌡️ Heating the bottom of the smartphone when charging can be a sign of poor connector contact or a defect in the cell itself.
- 📱 Bloating a new battery in the first weeks of use is a clear manufacturing defect requiring immediate replacement under warranty.
⚠️ Warning: If the battery starts to heat up quickly or swell after replacement, stop using the device immediately.Operation of the bloated battery may cause damage to the display or fire.
In case of software errors, a full charge-discharge cycle often helps: discharge the phone before turning off, then charge to 100% when off, then turn on and use as normal.
