Have you ever noticed that after updating the firmware on a Xiaomi smartphone or the Mi Band smartwatch, a strange parameter appeared in the battery settings - "energy recovery rate"? Or maybe the new Redmi or POCO specs mentioned "increased recovery efficiency" and you wondered what this means in practice?
This term sounds like something out of the electric car world or solar panels, but it's actually directly related to how your device manages battery charging, prolongs battery life, and even affects discharge rates. In this article, we'll look at what's behind it, how the energy recovery rate works in Xiaomi smartphones and gadgets, and why it's important to you as a user. Without complex formulas and technical details, only what's really useful in everyday use.
Spoiler: If you set this option correctly (where it is available), your Xiaomi can serve as a proxy for the game. 10-15% It's also going to help you avoid sudden blackouts when you're low. I wonder!
What is power recovery in Xiaomi devices?
To start with, energy recovery is the process of getting some of the energy back into the system, and in the context of smartphones and smart devices, it's about how the battery and electronics of Xiaomi devices interact to minimize power loss while operating.
A simple example: when you play a heavy game on the Redmi Note 12 Pro+, the processor and screen consume a lot of power, but some of that energy can be captured and returned to the battery, for example by optimizing the power controller or using the energy generated by braking (yes, smartphones have similar processes too!).
In Xiaomi devices, this is usually expressed as a percentage (e.g., 85% recovery) and depends on several factors:
- 🔋 Battery type: Lithium polymer (Li-Po) batteries in newer models (e.g. Xiaomi 14) are better at recovering energy than older lithium-ion (Li-Ion) batteries).
- 📱 Firmware optimization: B MIUI 14 And newer algorithms that increase recovery are added to the 5-10% compared MIUI 12.
- ⚡ Charging mode: Quick charging (e.g, 120W HyperCharge in Redmi Note 12 Pro+) It may temporarily reduce the degree of recovery.
- 🌡️ Temperature: Recovery efficiency drops when overheating – so in hot weather the battery goes down faster.
It’s important to understand that recovery isn’t about “free energy,” it’s about optimizing existing processes. It won’t make your POCO X5 last forever, but it will help it last longer on a single charge and wear out the battery more slowly.
How does the degree of recovery affect the smartphone?
Now, let's figure out what gives you a high degree of recovery in practice. Imagine two identical Xiaomi 13T smartphones:
- 🔴 First degree of recovery — 70%. It discharges faster, warms more when charging, and after a year the battery capacity will decrease by a factor of two. 15-20%.
- 🟢 The other one — 90%. It holds the charge longer, heats less, and after a year, the loss of capacity will be only one. 8-12%.
The difference is obvious! But how does recovery affect everyday use?
| Parameter | Low recovery (60-75%) | High recovery (85-95%) |
|---|---|---|
| Autonomous time | 10-15% less | 10-20% more. |
| Heat during charging | Strong (up to 45°C) | Moderate (up to 38°C) |
| Battery wear for the year | 15-25% | 5-12% |
| Stability of operation at low charge | Sudden shutdowns at 5-10% | Works up to 1-3% |
But there's a flip side to this: over-optimizing recovery can reduce performance. For example, some Xiaomi firmware artificially restricts CPU power to boost recovery, which can lead to lags in games or slow camera performance, so it's important to find a balance!
⚠️ Note: If after the update MIUI You noticed that the smartphone became slower to work, but at the same time in the battery settings appeared the option "energy recovery" with a high value (90%+), Try resetting the energy saving settings in Settings → Battery → Power modes. Sometimes the system over-optimizes the background processes too aggressively.
Where to see the degree of recovery on your Xiaomi?
Unfortunately, not all Xiaomi devices show this option in plain view, but there are several ways to find it or indirectly evaluate it:
- Enter the code ##4636### in the Phone app, then go to Battery Information. Some models (e.g. POCO F5) may display an Energy Reclamation Rate or similar option.
- In MIUI settings (new versions) Go to Settings → Battery → Battery Status. Some devices (e.g. Xiaomi 13 Ultra) have a Charging Efficiency Graph that indirectly reflects recovery.
- Using monitor apps, utilities like AccuBattery or Battery Guru can measure the charging/discharge efficiency associated with recovery.
If you don't find a direct indication of how much recovery you can get, don't worry. In most cases, this is hidden from the user, because it's more important to Xiaomi engineers than to ordinary smartphone owners. But it can be improved indirectly, as we'll talk about later.
💡
If the engineering menu doesn't have any data on recovery, but you want to evaluate the battery's health, use the code ##6484## (which works on many Redmi and POCO models), which displays the actual battery capacity in mAh, which will help you understand how worn out it is.
How to improve the degree of energy recovery?
The good news is that even if your device doesn't show a degree of recovery, you can improve its efficiency with a few simple steps.
Use the original power supply | Turn off overnight fast charging | Avoid overheating above 40°C | Update firmware to the latest version of MIUI |Reset battery settings every 3 months-->
1. Optimize charging
- 🔌 Use original chargers. Non-original power supplies (especially cheap ones) can reduce the efficiency of recovery on the back of the battery. 10-15%.
- 🌙 Night Charging: Enable Optimized Charging in the battery settings.It limits charge to 80% at night and brings it up to 100% by morning, which reduces wear and improves recovery.
- ⚡ Avoid extreme temperatures. Charge at temperatures below 10°C or higher than 35°C worsens recovery. 12S Ultra even has a sensor that blocks fast charging when overheated.
2.Tune the firmware.
- 📲 Update. MIUI. In the new versions (MIUI 14+) We've improved power management algorithms. K60 post-update MIUI 14.0.5 recovery increased by 7% compared to MIUI 13.
- 🔄 Reset the battery settings. Sometimes the calibration gets lost. → Battery → Three dots (menu) → Resetting battery settings.
3.Control the health of the battery
- 🩺 Check the container once in a while. 2-3 A month through an engineering menu or an app, if the actual capacity drops below. 80% From the nominal, recovery will be worse.
- 🔋 Avoid deep discharge. Regular discharges to 0% They kill recovery. Try to charge the device when you're in the middle of it. 10-20% charge.
Important: In Xiaomi smartphones with wireless charging support (for example, Xiaomi 13 Pro), the degree of recovery during wireless charging is 5-10% lower than with wired charging, this is due to energy loss in the coil.
Recovery Degree in Xiaomi Smart Watches and Fitness Bracelets
Not only smartphones, but also Xiaomi smart devices use energy recovery. In the Mi Band 8, Xiaomi Watch 2 Pro and other gadgets, this mechanism works a little differently:
- ⌚ Synchronization energy saving: When the bracelet transmits data to the Mi Fitness app, some of the energy used in the transmission is returned to the battery by streamlined Bluetooth protocols.
- 💤 Sleep mode: In Mi Band 7 Pro, when activating sleep mode, "deep recovery" is activated - the device turns off unnecessary sensors and redistributes energy to basic functions (time, pulse).
- ☀️ Solar charging (in some models): In Xiaomi Watch S1 Active is a small solar panel that converts light into energy. It's not full recovery, but it's a similar principle: the return of lost energy.
In smartwatches, recovery is less noticeable than in smartphones, but it extends the life of 10-30% depending on the model. For example, the Xiaomi Watch S3 with optimized recovery lasts up to 15 days on a single charge, while analogues without this feature only 10-12 days.
⚠️ Warning: If your Mi Band is rapidly discharged after a firmware update, check your notification settings. Frequent vibrations and phone sync reduce recovery efficiency. Turn off unnecessary alerts in the Mi Fitness app.
Myths and Truths About Xiaomi’s Energy Recovery
There's a lot of rumors going around this parameter, and let's look at what's true and what's fiction.
Myth 1
Really:
- ✅ Recovery extends battery life, but does not replace it.
- ✅ In the new smartphones Xiaomi (2023 year and later) degree of recovery by 15-20% higher than in models 2019-2020 year-end.
- ✅ Optimizing recovery can reduce performance in games 5-10%.
Myths:
- ❌ "Recovery works only with fast charging – in fact, it is always active, but with fast charging, its effectiveness may fall.
- ❌ "If you turn off recovery, the smartphone will work faster — this parameter can not be disabled manually, it is sewn into the firmware.
- ❌ "Recovery spoils the battery – on the contrary, it slows down wear if configured correctly.
