The code *#*#6485#*#* can open battery information on some Xiaomi, Redmi and POCO software, but it is not a universal battery-health report. Availability, labels and values vary. Do not decide that a battery is worn out from an unexplained MB or MF field alone.

How to check whether the menu is available
- Open the phone’s normal dialler.
- Enter
*#*#6485#*#*. - If an information screen opens automatically, read the displayed labels without changing anything.
- If nothing opens, stop there. Do not assume every MIUI or HyperOS version supports it.
This is a model-dependent diagnostic shortcut, not a reason to install an unknown dialler, grant extra permissions or try unrelated service codes. We cannot verify a complete official field dictionary for every Xiaomi, POCO or Redmi model.
What do MB_5, MB_06 and MF_05 mean?
You may see advice online about these labels, but field names copied from another phone are not a reliable answer for yours. MB_5 may also be a mistyped or shortened label. Read the entire label, units, device model and software version before comparing values.
| What you see | What you can safely conclude |
|---|---|
| A clearly labelled cycle counter | It is a reported counter; check what that model counts. |
| A current charge percentage | It describes charge remaining now, not remaining original capacity. |
| An MB/MF code without documented units | Its meaning needs model-specific confirmation. |
| A status such as Good | It is not a precise percentage of original capacity or a guarantee of future life. |
Do not automatically divide MF_05 by MF_06 and call the result an accurate health percentage. That calculation needs confirmed meanings, matching units and reliable measurements for the exact phone.
Try the normal battery settings first
Open Settings > Battery and look for the information offered by your model, such as Battery protection. Xiaomi documents Number of charges today on the REDMI 13C and a similar Xiaomi 14T Pro feature.
A daily charging-session count is not automatically a lifetime full-cycle count. Partial top-ups, current capacity and charge remaining describe different things. Do not compare them as if they were the same metric.
Does 500 cycles mean the battery must be replaced?
No fixed counter alone tells every phone owner to replace a battery. Model specifications, ageing, temperature, runtime and actual faults matter. A battery estimate from an app is also an estimate, not a laboratory capacity test.
Investigate repeated shutdowns, poor runtime or unusual heat using the maker’s support guidance. If a battery is swollen, stop using and charging the device and arrange proper service. Our charging-heat guide covers a related symptom.
If the phone is still safe and supported but no longer your main handset, our old-phone reuse guide offers practical options. A single unexplained menu value is not a reason to buy another phone.
