The average life of a lithium-ion battery is 2-3 years (or 500-800 full charge cycles), and then the capacity drops by 20 to 30 percent, and the phone starts to behave unpredictably. Here are the key symptoms that the battery should be replaced:

• 🔋 Fast discharge: the phone sits down in 3-4 hours with moderate use (previously kept the day on).
• 📉 Charge jumps: for example, from 40% immediately drops to 15%, or the phone turns off at 20-30%.
• 🔥 Overheating during charging or playing (the battery gets hot, the body heats up).
• ⚡ Slow charging: even with the original RAM, the phone charges 3-4 hours instead of 1-1.5.
• 💥 Battery bloating (seen from the raised screen or warping of the back cover).

If you notice at least 2-3 signs from the list, the diagnosis will confirm wear.

• 📱 Through the phone menu: Settings → Battery → The state of the battery (on some models shows the percentage of wear).
• 🔧 With applications like AccuBattery (Android) or AIDA64.
• 🔌 Connect your phone to your PC and use the Mi Flash Tool (for advanced users).

⚠️ Warning: If the battery is swollen, immediately disconnect the phone from charging and do not use it until replaced! lithium-ion batteries can ignite if damaged.
