Quick answer

Appears in the notification panel when your Honor phone or tablet stops charging at 80% or higher and hides the charging icon because Smart Charge is active. Touch Resume Charging in the prompt or manage it in Settings > Battery.

Safety first

Stop and check this first

  • If the battery appears swollen, deformed, or abnormally hot during charging, stop using the device immediately, never open the casing yourself, and use official service.
  • Back up your data before taking your phone or tablet to an HONOR Authorized Service Center, as diagnostic testing or service may reset the device.

Safe checks you can perform

  • Swipe down the notification panel and touch Resume Charging
  • Check the Smart Charge switch in Settings > Battery > More battery settings
  • Press the power bank button or reconnect the cable when using a power bank

These are the steps they must carry out and show you. Tick them as they work: if steps are skipped, do not accept a part swap.

These are not instructions for opening or handling the equipment yourself. They are the checks that should support a technical conclusion.

  1. Official HONOR Support inquiry for Smart Charge behavior on your model

Before accepting a part or repair

Nothing has been shown yet. Do not accept a part swap based on the code alone.

Follow these steps

Note: Follow the documented order. An error code identifies the affected system, but it does not prove by itself which part has failed.

  1. Swipe down the notification panel and touch Resume Charging

    No special tools

    Who:
    you, while your Honor phone or tablet is plugged in and paused at 80%.
    How:
    swipe down from the status bar to open the notification panel, locate the Smart Charge dialog box, and touch Resume Charging to immediately continue charging to 100%.
    Result that matters:
    the charging icon reappearing and the battery charging to 100% without disabling Smart Charge for future sessions.
    If charging resumes right away after touching Resume Charging:
    Smart Charge was simply protecting the battery.
    If you do not want charging to pause at 80% in the future:
    check the toggle in More battery settings.
    Evidence to keep:
    a screenshot of the Smart Charge dialog box in the notification panel.

    Evidence: HONOR Support - Phone or tablet stops charging when the charging progress reaches 80% (Smart Charge)

  2. Check the Smart Charge switch in Settings > Battery > More battery settings

    No special tools

    Who:
    you, in the battery settings menu of your Honor device.
    How:
    open Settings > Battery > More battery settings and check whether Smart Charge is enabled; turn it off if you prefer not to pause charging at 80%.
    Result that matters:
    disabling the automatic 80% charging pause managed by built-in AI learning.
    If turning off Smart Charge allows continuous charging to 100%:
    the feature was working as designed.
    If you are charging with a power bank and it still disconnects above 80%:
    follow the next check.
    Evidence to keep:
    the status of the Smart Charge switch inside More battery settings.

    Evidence: HONOR Support - Phone or tablet stops charging when the charging progress reaches 80% (Smart Charge)

  3. Press the power bank button or reconnect the cable when using a power bank

    No special tools

    Who:
    you, when charging your Honor phone or tablet from a portable power bank.
    How:
    if charging stops above 80% on a power bank, press the power button on the power bank or unplug and reconnect the charging cable to wake the power bank output.
    Result that matters:
    waking the power bank after it shut off when Smart Charge lowered the current near 0 mA.
    If the power bank resumes output and charging continues to 100%:
    no fault exists.
    If Smart Charge is turned off and the device still stops at 80% on a wall charger:
    take your Honor device and proof of purchase to an HONOR Authorized Service Center.
    Evidence to keep:
    the battery percentage where charging stopped and whether a power bank or wall adapter was used.

    Evidence: HONOR Support - Phone or tablet stops charging when the charging progress reaches 80% (Smart Charge)

What it means

The battery management subsystem in MagicOS and Magic UI enables Smart Charge by default to extend battery lifespan. Using built-in AI learning to recognize your routine, such as overnight charging or keeping the battery above 80% for long periods, the system pauses charging at 80%, removes the charging icon from the status bar, and displays a Smart Charge dialog box in the notification panel until shortly before you need the device. This notification alone never proves that your battery, adapter, or charging port is faulty.

Warnings and stop conditions

Symptoms and causes

Probable causes · in order

  • Smart Charge enabled by default after AI learns your charging habitsCommon

    Built-in AI detects extended or nighttime charging routines and pauses charging at 80% to avoid holding the battery at full capacity for hours, slowing battery aging.

    Evidence: HONOR Support - Phone or tablet stops charging when the charging progress reaches 80% (Smart Charge)

  • Power bank auto-shutoff when Smart Charge drops current near 0 mAPossible

    When charging from a power bank above 80%, Smart Charge reduces the charging current close to 0 mA, causing the power bank to assume charging is finished and turn off its output.

    Evidence: HONOR Support - Phone or tablet stops charging when the charging progress reaches 80% (Smart Charge)

  • Charging still stops at 80% even after Smart Charge is turned offLess common

    If you have manually disabled Smart Charge in Settings > Battery > More battery settings and charging still halts at 80%, the device may need professional inspection.
