Why an Honor Android smartphone takes a long time to charge: diagnostics and correction

Have you noticed that your Honor has taken an unusually long time to charge? If previously the battery was filled in an hour and a half, but now the process takes 3-4 hours (or even worse - the phone does not recognize charging at all), the problem requires immediate attention. Slow charging is not just annoying - it signals problems that can worsen over time: from loss of battery capacity to failure of the power controller.

In this article we will analyze all possible causeswhy Honor on Android began to charge slowly - from banal (damaged cable) to hidden (software restrictions on power consumption). You will receive step-by-step guide to diagnose each of them, as well as ways to eliminate them without contacting a service center. We will pay special attention to models Honor 10/20/30/50/70/90 series and Magicwhere the problem occurs most often.

⚠️ Important: If, after checking all points, charging remains slow, this may indicate hardware wear of the power controller or battery —in this case, professional diagnostics will be required. Do not ignore the problem: long-term charging with low currents reduces the battery life by 2-3 times.

Before starting repairs, answer one question:

1. Problems with the charger or cable

Let's start with the most obvious: 90% of cases of slow charging related to a faulty charger (charger) or cable. Even if visually they look intact, internal damage - microcracks in the wires, oxidation of contacts or failure of resistors in the power supply - can reduce the charging current by 2-5 times.

How to check:

• 🔌 Use the original charger from Honor/Huawei (with a power of at least 18W for modern models). Counterfeits often produce less current, even if the label says 20W/40W.
• 🔍 Inspect the cable to check for kinks, especially at the base of the connector. Try shaking the plug in the phone socket - if charging is interrupted, the problem is in the contacts.
• ⚡ Connect the phone to another charger (for example, from a laptop or power bank). If the charging speed has increased, the power supply is to blame.

⚠️ Attention: Using uncertified chargers with a higher voltage 5V (for example, 9V/12V from a laptop) can lead to overheating of the power controller phones Honor older than 2019. They do not support the protocol Quick Charge and do not regulate the incoming voltage.

If you use wireless charging, please note: even with the power of the stations 10W-15W the real charging speed Honor rarely exceeds 5W due to firmware limitations. This is normal, but do not expect quick results.

2. The connector is dirty or damaged USB-C

Connector USB-C in smartphones Honor is one of the most vulnerable places. Dust, lint from pockets, moisture or mechanical damage (for example, after a fall) disrupt the contact between the cable plug and the phone. As a result:

• 📉 Charging current. drops to 0.5A-1A (instead of standard 2A-3A).
• ⚡ Charging is interrupted at the slightest movement of the cable.
• 🔋 The phone shows a message "Slow charging" or "The charger is not supported".

How to clean the connector:

1. Turn off the phone and remove the SIM card/memory card.
2. Illuminate the connector with a flashlight - if dust or debris is visible inside, carefully remove it toothpick (not with a metal object!).
3. To remove oxidation, use alcohol wipes (do not overdo it with moisture!).
4. Let the phone dry for 10-15 minutes before connecting the charger.

⚠️ Attention: If the connector loose or has play, do not try to repair it yourself - this requires soldering at the micro level. Contact service, otherwise you risk damaging the motherboard.

What to do if liquid gets into the connector?

Immediately turn off the phone and remove the battery (if possible). Blot the connector with a napkin, then place the device in a bag of silica gel for 24-48 hours. Do not turn on the phone until you are sure it is completely dry (check with a multimeter or at a service center).

3. Software restrictions: power saving mode and background processes on smartphones aggressively optimizes power consumption, especially on models with. In some cases, the system artificially limits the charging current if:

Android on smartphones Honor aggressively optimizes power consumption, especially on models with EMUI/Magic UI. In some cases, the system artificially limits the charging current if:

• 🔋 Power saving mode is enabled energy saving mode (Settings → Battery → Power saving mode).
• 📱 The phone gets very hot (above 40°C) - overheating protection is activated.
• 🔄 Resource-intensive applications are running (games, video editing, Google Maps in navigation).

How to remove restrictions:

1. Disable the mode energy saving: go to Settings → Battery and deactivate the option.
2. Close all background applications via Recent tasks (swipe up from the bottom edge of the screen).
3. Check the phone temperature: if it is hot, let it cool for 10-15 minutes before charging.
4. Update the firmware: there may be a fix for charging bugs. Settings → System → Software update There may be a fix for charging bugs.

💡 Tip: On models Honor 50/60/70 series there is a hidden setting "Fast charging", which sometimes resets after updates. To enable it:

Settings → Battery → Advanced → Fast charging (enable)

4. Battery wear: how to check and what to do

Lithium polymer batteries in smartphones Honor are designed for 300-500 charging cycles, after which their capacity drops by 20-30%. If your phone is older than 2 years, there is a good chance that the battery is worn out. Signs:

• 📉 The phone discharges in 3-4 hours with moderate use.
• ⚡ Charging stops at 80-90% and does not go further.
• 🔋 Full charging time has increased 2-3 times.

How to check the battery status:

1. Install the application AccuBattery (free in Google Play).
2. Charge the phone to 100% and see the indicator "Battery health" (below 80% is critical).
3. Check the number of charge cycles in Settings → Battery → Battery condition (if available).

What to do if the battery is worn out:

• 🔧 Replacement battery is the only solution. The cost for Honor varies from 1,500 to 4,000 rubles (depending on the model).
• 📱 If replacement is not possible, use power bank to recharge on the go.
• ⚡ Disable fast charging in the settings - this will extend the life of the battery for several more months.

⚠️ Attention: On models Honor 8X, 9X, 10 Lite the battery is soldered to the motherboard. Replacing it requires complete disassembly of the phone and soldering - do not trust this to unverified workshops!

Model Honor	Typical battery life	Replacement cost (approx.)	Difficulty of replacement
Honor 10/20 Pro	2-3 years	2 000–3 500 ₽	Average (adhesive battery)
Honor 50/60	2.5-3.5 years	2 500–4 000 ₽	High (sealed case)
Honor 70/90	3-4 years	3 000–4 500 ₽	Very high (double-layer battery)
Honor Magic 3/4	3-4 years	4 000–6 000 ₽	Expert (cooling system)

5. Problems with firmware or resetting

Sometimes slow charging is a consequence software failure, especially after an update EMUI/Magic UI. For example, in the firmware for Honor 30/50 series there was a bug due to which the power controller did not correctly recognize chargers. Also, the problem may occur after:

• 📱 Unsuccessful update (interrupted or with errors).
• 🔧 Resetting to factory settings without correct configuration energy profile.
• 🛠️ Rooting or installing custom firmware.

How to fix:

1. Reset battery settings: go to Settings → Applications → Three dots (⋮) → Reset application settings.
2. Update the firmware: Check for updates in Settings → System → Software update.
3. Reset to factory settings:

   Settings → System → Reset → Reset all settings

   Attention: Make a backup copy of your data first!
4. Reflash the phone via Huawei eRecovery (for models on EMUI) or HiSuite (for Magic UI).

⚠️ Attention: If you installed custom software (for example, LineageOS), the problem may be due to incorrect kernel firmware. In this case, return to the official firmware via fastboot.

How to enter eRecovery mode on Honor?

Turn off the phone Volume up + Power for 10 seconds in the menu. select Download latest version and recovery (use the volume keys to navigate).

6. Hardware faults: power controller and motherboard

If all the previous steps did not help, the problem lies in hardware:

• 🔌 The power controller is faulty (a common problem after falls or moisture).
• 📱 The motherboard is damaged (for example, after an unsuccessful repair).
• ⚡ Short circuit in the power circuit (can manifest itself as slow charging + spontaneous reboots).

Signs of a hardware malfunction:

• 📉 The phone charges only in in the off state.
• ⚡ Charging occurs in jerks: sometimes quickly, sometimes slowly.
• 🔋 The battery is discharged even when the charger is connected.
• 💥 The phone is heating up in the charging connector area.

What to do:

1. Contact the service center for diagnostics. Repairing the power controller will cost 3 000–8 000 ₽ (depending on the model).
2. Check warranty: if the phone is less than 1 year old, repairs can be free (provided that the problem is not caused by mechanical damage).
3. Do not use the phone until repair - a short circuit can damage other components.

⚠️ Attention: On models Honor View 20, Magic 2 the power controller is integrated into the processor Kirin 980. Replacing it is equivalent to replacing the motherboard (cost is up to 70% of the price of a new phone).

7. External factors: temperature, humidity, magnetic fields

Even a serviceable one Honor can charge slowly due to external conditions:

• 🌡️ Low temperature (below 0°C): lithium-ion batteries do not accept a charge well in the cold.
• ☀️ Overheating (above 45°C): the system automatically reduces the current.
• 🧲 Magnetic fields (for example, near speakers or wireless chargers): may cause interference.
• 💦 High humidity: condensation in the connector worsens contact.

Recommendations:

• Charge the phone at room temperature (10°C–30°C).
• Do not place the phone on soft surfaces (sofa, bed) - this will block ventilation.
• Avoid charging near heat sources (battery, heater).
• If the phone overheats, unplug it and let it cool.

💡 Tip: On models Honor with 5G support (for example, Honor 50 Pro, Magic 3) charging may slow down when the mobile data is active due to the heating of the modem. Switch to 4G or Wi-Fi while charging.

FAQ: Frequently asked questions about slow charging Honor

❓ Why does Honor charge slowly only at night?

Most likely, the function is enabled "Adaptive charging" (Settings → Battery → Adaptive charging). It limits the current after 80% to extend battery life. Disable it if you need fast charging.

❓ Can I use iPhone charging for Honor?

It is possible, but the speed will be limited 5W (USB 2.0 standard). Chargers Apple do not support protocols Quick Charge or SuperChargethat are used in Honor.

❓ Why does the phone charge quickly up to 80%, and then slowly?

This is normal behavior for lithium-ion batteries. After 80%, the system reduces the current to reduce heat and extend battery life. On models Honor with SuperCharge (for example, Magic 4 Pro), the threshold can be higher - up to 90%.

❓ How to check the real charging current?

Install application AccuBattery or Ampere (from Google Play). They show the current current in milliamps (mA). For fast charging, the value should be 1500–3000 mA (depending on the model).

❓ Could a virus cause slow charging?

Theoretically, yes, if the virus loads the processor in the background (for example, it mines cryptocurrency). Check your phone with an antivirus (Dr.Web, Kaspersky) and look at the battery consumption in Settings → Battery → Battery usage.
