| Custom limit in the phone/tablet battery settings |
The lifespan of a battery is closely related to the charging routine. Reducing the time that the battery is fully charged can slow down the battery aging. Custom limit has been added to the battery module on phones and tablets running HarmonyOS 2.0 or later. This feature can help prolong your battery's lifespan.
Setting method:
Go to Settings > Battery > More battery settings/Battery health > Custom limit to set the maximum battery level to 70%, 80%, 90%, or 100%. It is recommended that you set a value between 70% and 90% for daily use.
This feature is disabled by default. You can set the maximum battery level to whatever value you need.
"Custom charging is on" notification:
When Custom limit is enabled (maximum battery level set to a value below 100%), a "Custom charging is on" notification will display each time the device charges, and charging will automatically stop once the battery level reaches the preset maximum level. To have your device fully charged, touch Fully charge on the notification.
This feature and the user interface may vary depending on the device and software version.

Which device models support Custom limit? |
P50 Pocket/Mate Xs 2/Mate 50 Pro/Mate 50/MatePad/MediaPad M6 running HarmonyOS 2.0 MatePad Pro and MatePad SE running HarmonyOS 3.0 If your device does not support this feature, please stay tuned for system updates. |
What are the key differences between Custom limit and Smart charge? |
Both features help slow down battery aging and prolong the battery lifespan. Smart charge learns from your charging routine and authorizes the system to charge the battery to 80% as needed. Custom limit allows you to set a maximum battery level based on your own personal needs. Custom limit and Smart charge cannot be enabled or disabled at the same time. If one of them is enabled, the other will be disabled automatically. |
Which charging modes does Custom limit support? |
When Custom limit is enabled (maximum battery level set to a value below 100%), all charging modes, including wired charging, wireless charging, in-car charging, and USB charging, are supported, and can trigger the "Custom charging is on" notification. |
Can I disable the "Custom charging is on" notification? |
The notification will only disappear when you touch Fully charge or halt the charging. It plays no sound, and is only visible after you swipe down from the top edge of the screen to display the notification panel when the screen is locked, or when the device is being charged with the screen off. |
Will Custom limit affect the charging speed and power, or cause my device to heat up? |
No. Custom limit only prevents your device from being charged when the battery level has reached the preset maximum value. Therefore, it will not affect the charging speed and power, or cause your device to heat up. |
In which scenarios is Custom limit preferentially used? What is the recommended value for this feature? |
If your tablet/phone needs to connect to its charger for a long time, such as during an online class, navigation, or live stream, 70% (minimum) is recommended. If you do not connect your device to the charger for a long time, 80% is recommended for daily use. You can also touch Fully charge on the notification panel to have your battery fully charged. |
