What does "Max xxW" mean on the charging animation screen?

Problem:

After a phone that supports super fast charging with a 40 W, 55 W, or higher output is updated to EMUI 10.1, "Max xxW" is displayed on the lock screen when the user uses a standard charger and cable (or a wireless charger stand) to charge the phone. When the user charges the phone with another charger or data cable, the text may disappear.

Cause:

The "Max xxW" text has been displayed on the charging screen since EMUI 10.1 and later. The meaning of this message varies depending on the charging scenario.

1. Wired charging:
   • The message "Max xxW" indicates that you are using a charger with the maximum power of xxW.
   • When your phone uses a charger with a rated power higher than xxW, the message "Max xxW" means that this is equivalent to charging with a charger of xxW.
     

     If the wired charging power is less than 40 W, "Max xxW" is not displayed.

2. Wireless charging:
   • The message "Max xxW" indicates that the maximum wireless charging power is xx W.
     

     If the wireless charging power is less than 27 W, "Max xxW" is not displayed.

3. If "Max xxW" disappears, it indicates that the charging power has not reached the maximum (xx W).

Solution:

• If "Max xxW" used to display on your phone during charging, but does not display anymore, it is recommended that you use the standard charger and data cable.
• If the issue persists after you use the standard charger and data cable, back up your data and take your device and the proof of purchase to an authorized Huawei Customer Service Center for assistance.
