4 Hardware Methods: When Software Optimization Does Not Help

If after all the settings, the battery still discharges too quickly, the problem may be in the hardware:

Replacement of the battery

Lithium-ion batteries lose capacity after 300-500 Charging cycles. Wear can be checked:

1. Enter the code in the phone app: ##4636##.
2. Go to Battery Information and see Health Level.
3. If the value is below 80%, the battery needs to be replaced.

💡 Tip: On Xiaomi phones with fast charging (for example, Xiaomi 12 Pro with a high-speed charger) 120W) To extend its life, charge your phone to 80% and avoid overheating.

Calibration of the battery

Sometimes the battery controller does not display the charge level correctly (e.g. the phone turns off at 20%).

1. Discharge the phone before automatically shutting down.
2. Connect the charger and wait 100% (don’t turn on the phone!).
3. Turn off the charging, turn on the phone and recharge to 100%.

⚠️ Note: Do not use “smart” chargers with automatic shutdown during calibration – they can interrupt the process. 95-98%, This will result in inaccurate data from the controller.

Checking for hardware faults

If the battery runs out on a phone that is turned off (more than 5% per night), the following problems may occur:

• 🔌 Faulty power controller (for example, after falling or getting moisture).
• 📱 Short circuit in the screen plume or buttons.
• 🔋 Battery bloating (check if the back cover is moving away).

🔧 Solution: Contact Xiaomi Service Center for Diagnostics. Self-repair may result in loss of warranty or damage to the fee.

5. Hidden functions MIUI maximum savings

MIUI It hides a few useful options that you can't see in the standard menu, and you can activate them through codes or developer settings.

8. Myths about battery saving on Xiaomi

There are a lot of tips on the Internet that not only don't help, but also harm the phone.

8.1. “You need to discharge the phone up to 0% once a month”

❌ Reality: Modern lithium-ion batteries don't require full discharge. On the contrary, deep discharges shorten lifespan.

8.2. “Closing applications from multitasking saves charge”

❌ Reality: Android and MIUI Optimized for memory management. Forced shutdown of applications causes the system to waste energy on re-runs.

“Switching off” GPS Always saves battery"

⚠️ Nuance: Modern chips (e.g. Snapdragon 8 Gen 2) use low-energy GPS. Its consumption is minimal if not actively used (for example, in the navigator). GPS It only makes sense if you don’t use it at all.

“Fast charging spoils the battery”

⚠️ Nuance: Quick charging by itself (e.g, 120W Xiaomi 12 Pro does not harm if it is:

• The original charger is used.
• The phone does not overheat (optimal temperature — 25-35°C).
• Charging stops at 80-85% for everyday use.
