Why does my phone charge slowly after a system update?


After the phone has just been updated, the phone charges slowly or cannot be charged, or heats up during charging.


Your phone undergoes a series of optimisations in the background upon system update, which increases power consumption. Some apps need to be readapted and optimised in the background, Gallery will be reorganised, and files will be scanned again to detect security risks. These operations consume a lot of power and may cause your phone to overheat. In this case, your phone will enable its overheating protection mechanism. The phone may then automatically reduce the charging current to ensure battery safety. Therefore, it's normal for your phone to charge slowly or to be unable to charge, or to heat up after a phone update. Generally, this type of issue will no longer occur if you keep the phone idle after a full charge or after three days of normal usage. The time for your phone to return to its normal condition could take longer if the phone is used repeatedly.


  1. If you have just updated your phone to the latest version, wait for several days and check the charging status. During this period, place your phone in a ventilated environment.
  2. If the problem persists, take your phone and proof of purchase to an authorised Huawei Customer Service Centre for assistance.
