The situation when your favorite Honor smartphone, which yesterday reached its full capacity in an hour, today heats up at the outlet for several hours, is familiar to many users. Slow charging is not just annoying, disrupting the usual rhythm of life, but can also signal more serious malfunctions in the hardware or software of the device. Understanding why the phone takes a long time to chargeis the first step to fixing the problem without the need to immediately contact a service center.
There are many factors that influence the speed of energy replenishment: from the quality of the cable itself and the power supply to the energy saving settings in the Magic UI shell. Often, gadget owners do not notice how background processes or physical wear and tear on connectors begin to slow down this critical process. In this article, we will analyze in detail all possible scenarios and offer proven diagnostic methods.
Before you panic and take the device for repair, it is worth conducting an initial visual and software check. Android-systems installed on Honor have flexible power management mechanisms, which can sometimes work incorrectly or block fast charging for the sake of battery safety. Let's look at how to distinguish a software failure from a physical breakdown.
Problems with the charger and cable
The most banal, but most common reason why Honor smartphone gains energy slowly, due to damage to components. Cables are subject to constant mechanical stress: kinks, twisting and jerking, which over time leads to internal breaks in the conductors. Even if the wire looks intact outwardly, its throughput could drop to a minimum, supporting only the slow charging mode.
The second element of the circuit is the power supply. Many users use old adapters or cheap analogues from markets that do not support modern fast charging protocols, such as SuperCharge or Quick Charge. If the phone "sees" the power supply as a weak current source, it automatically limits the incoming current to avoid overheating and damage to the power controller.
⚠️ Warning: Using uncertified cheap chargers can lead to voltage surges, which is dangerous for the power controller of your Honor. Always check the markings of the block.
It is also worth checking the condition of the USB port itself on the phone. Over time, dust, lint from pockets and other dirt accumulate inside the connector, which prevents the cable plug from making tight contact. This creates additional resistance in the circuit, which is why charging is slow or is interrupted at the slightest movement.
The influence of background processes and applications
Operating system Android on Honor smartphones allows many applications to run in background, consuming processor resources and, accordingly, battery energy. If, while charging, you left “heavy” apps, a navigator, active cloud synchronization or mobile data on, the phone can charge for an extremely long time, since the energy consumed will be almost equal to the incoming one.
Particular attention should be paid to the processes that “woke up” the phone during idle time. Sometimes a malfunctioning application can cause cyclic reboots of services or constant network searching, which creates a high load on the system. In such cases, battery does not receive enough current for fast charging, since it is immediately spent on system operation.
To identify the culprit, you can use the built-in battery consumption statistics. This will help you understand whether slow charging is a consequence of abnormal activity of a particular software. Often it is enough to close unnecessary tabs or switch the device to airplane mode while charging to significantly speed up the process.
For the fastest charging, turn on the "Airplane" mode or turn off the smartphone completely if you urgently need to replenish the energy supply.
Temperature conditions and overheating of the device
Lithium-polymer The batteries used in modern Honor smartphones are extremely sensitive to temperature. The power controller specifically slows down the charging speed if sensors detect overheating of the case or the battery itself. This is a safety mechanism designed to prevent the battery from swelling or catching fire, but to the user it looks like a malfunction.
Often phones get hot if you charge them in the sun, on a soft surface (sofa, pillow) that interferes with heat transfer, or while using navigation and games. In such conditions, charging speed can drop significantly until the device cools down to safe values.
The opposite situation is charging in severe frost. At low temperatures, the chemical reactions inside the battery slow down and the controller also limits the current. If you brought your phone from outside into a warm place, let it warm up to room temperature before charging it.
| Condition | Temperature (approximately) | System response |
|---|---|---|
| Normal | 15°C – 35°C | Full charging speed |
| Overheating | Above 40°C | Severe current limitation or stops |
| Hypothermia | Below 0°C | Slow down or prohibit charging |
| Critical heating | Above 45-50°C | Complete charge shutdown |
Battery wear and hardware problems
Any battery has a limited resource of charge-discharge cycles. Over time, usually after 500-800 full cycles, the battery capacity decreases and internal resistance increases. A worn-out one may charge unevenly: quickly gain the first percent and then take a very long time to “get” the rest, or the system may incorrectly calibrate the charge level. Honor battery It may charge unevenly: quickly gain the first percentage and then take a very long time to “get” the rest, or the system may not calibrate the charge level correctly.
Hardware problems also include malfunctions of the power controller on the motherboard or oxidation of the contacts inside the charging socket itself. If you notice that the phone takes a long time to charge only when the cable is in a certain position, most likely the problem lies in mechanical damage to the connector or cable.
How to check battery wear without applications?
On some Honor models, in the engineering menu (dial code ##2846579## in the dialer) you can see the battery status. Look for the section "ProjectMenu" → "Single Test" → "Battery Test". The current status will be displayed there: Good or Bad.
Visual inspection can also give clues. If the back cover of the smartphone begins to come off or the screen rises slightly, this is a sure sign of a swollen battery. Operating such a device is dangerous, and slow charging is the least of the problems here.
Energy saving settings and optimization
The Magic UI shell installed on Honor smartphones has aggressive energy saving algorithms. Sometimes optimization settings can conflict with the fast charging process. For example, turning on Ultra Power Saving mode may limit background activity but also affect current distribution priorities.
It is worth checking whether the Smart Charging function is enabled. It analyzes your habits and, if you charge your phone at night, it can deliberately slow down the process after reaching 80% to finish charging right when you wake up. This extends the life of the battery, but creates the illusion of failure.
Resetting the network settings or a full factory reset (as a last resort) can help if the problem is caused by a software glitch in the power management system. Before this, it is recommended to check for system updates, since new versions Android often fix such bugs.
☑️ Checking charging settings
Honor charging speed comparison
Understanding what speed is normal for your model will help you avoid false alarms. Different Honor series are equipped with different technologies. Flagship models support ultra-fast protocols, while budget models can be charged at a standard 10 W.
Below is a table showing the approximate full charging time for different technologies used in the brand's devices. Please note that actual times may vary depending on operating conditions.
| Technology | Power (W) | Charging time (0-100%) | Example models |
|---|---|---|---|
| SuperCharge | 66 W and above | 30-40 minutes | Honor 50/60/70/80/90 Pro |
| SuperCharge | 22.5 - 40 W | 50-60 minutes | Honor X8, Honor 50 Lite |
| Standard Charge | 10 W | 2.5 - 3 hours | Budget models (Y series, Play) |
If your phone that supports fast charging is charging at standard speed (10 W), check to see if the lightning bolt icon with two arrows (or SuperCharge) is lit on the screen. If a regular lightning bolt is displayed, it means that the fast charging protocol is not activated.
The absence of a fast charging icon on the screen when connecting the original unit most often indicates dirt in the port or damage to the cable.
When it’s time to take the phone to the service
If you have tried all the methods: changed the cable, cleaned the port, reset, but the phone takes a long time to charge or it heats up to uncomfortable temperatures, the problem is probably hardware. Internal malfunctions of the power controller or the battery itself require professional diagnostics.
A particularly alarming signal is a sharp drop in the charge percentage (for example, from 40% to 5% in a few minutes) in combination with slow charging. This indicates deep degradation of the battery cells, which need to be replaced.
⚠️ Attention: Opening your Honor smartphone yourself can lead to loss of warranty and damage to moisture-proof seals. If you suspect a hardware malfunction, it is better to contact authorized specialists.
Do not ignore the problem of slow charging. Leaving the phone near a power outlet for a long time with a faulty controller can lead to overheating and failure of other components of the motherboard. Timely replacement of the cable or battery will cost less than repairing the board.
Is it possible to charge a phone from a Power Bank?
Yes, but the speed will depend on the output current of the Power Bank. If the external battery only produces 1A (5W), charging will be very slow, even if the phone supports 66W.
Why does the phone only charge up to 80%?
Most likely, you have the Smart Charging or Optimized Charging feature enabled. It's designed to extend battery life by pausing charging at 80% and ending just before your usual wake-up time. You can disable this in the battery settings.
Is it harmful to use a phone while charging?
Using a smartphone while charging, especially in “heavy” applications or games, causes additional heating. This causes the controller to reduce the charging current, increasing the total time. In the long run, this accelerates battery wear.
How to clean a USB port at home?
Use a wooden toothpick or a plastic toothpick (not a metal needle!). Carefully, without strong pressure, clean the lint from the depths of the connector. You can also use compressed air or a blower to blow out the dust.
Is it true that airplane mode speeds up charging?
Yes, it is true. Airplane mode disables Wi-Fi, Bluetooth and cellular communications, which consume a significant portion of power in standby mode. This allows you to direct more current directly to replenish the battery capacity.
