Replacing the battery with Xiaomi Redmi Note 10 Pro - a task that every owner of this popular smartphone faces sooner or later. Even with careful use, battery capacity decreases by 20-30% after just 2-3 years, and in some cases (for example, with frequent use of fast charging or extreme temperatures) degradation occurs even faster. If your device begins to discharge within a few hours, turns off spontaneously, or heats up while charging, it's most likely time to replace the battery.
In this article we will analyze in detail the entire process: from fault diagnosis to final assembly. You will learn how to choose a quality battery, what tools you will need, and how to avoid common mistakes that can damage your smartphone. We will pay special attention security — Working with lithium-ion batteries requires caution, and we will tell you how to minimize the risks.
How to understand that the battery Redmi Note 10 Pro needs replacement?
Before disassembling the phone, make sure that the problem is really in the battery. Here are the key signs that indicate battery wear:
- 🔋 Reduced operating time - if previously the charge lasted for a day, but now the phone is discharged in 4-5 hours with normal use.
- 🔥 Overheating while charging — the case becomes hot even when using the original charger.
- ⚡ Intermittent charge level - for example, from 40% it immediately drops to 15% or the phone turns off at 20–30% charge.
- 🛑 Spontaneous reboots — the device turns off, even if the indicator shows a sufficient charge level.
- 📉 Battery swelling — if the back cover of the phone begins to bulge or gaps appear between the case and the screen.
If you experience at least 2-3 of these symptoms, there is a 90% chance your battery is worn out. For accurate diagnosis, you can use applications like AccuBattery (available in Google Play), which show the actual capacity of the battery and the degree of its degradation. For example, if the initial capacity Redmi Note 10 Pro amounts to 5020 mAh, and the application shows 3500–4000 mAh, it's time to change the battery.
⚠️ Attention: If the battery is swollen, stop using your phone immediately. Lithium-ion batteries in this condition may ignite or explode if subjected to mechanical stress. Do not try to disassemble the phone yourself - contact a service center.
It's also worth checking to see if the problem is software related. Sometimes background processes or viruses cause rapid discharge. To do this:
- Go to
Settings → Battery and Performance → Battery Usage. - See which apps are consuming the most energy.
- If there are unknown or suspicious programs among them, remove them.
- Perform a factory reset (don't forget to back up your data!).
- Every 2 years
- Only when the phone stops working
- Never changed
- I'm buying a new phone
Which battery to choose for Redmi Note 10 Pro?
Not only the operating time of the phone, but also its safety depends on the quality of the battery. There are three types of batteries on the market for Redmi Note 10 Pro:
