Turn Wi-Fi On or Off auf Huawei
Wi-Fi on a Huawei phone is managed through a single toggle, but its state affects more than just internet speed. When Wi-Fi is active, the phone constantly scans for known networks, which uses a small amount of battery even without an active connection. When Wi-Fi is off, every data request falls back to mobile data, which can quickly use up a limited plan.
You should turn Wi-Fi off when you leave a covered area for a longer period, for example during travel, since the constant scanning for networks that are out of range adds up over a full day. You should turn it back on as soon as you are near a trusted network, so the phone can connect automatically instead of relying on mobile data.
To change the setting, go to Open the settings ➔ Tap on Wi-Fi ➔ Activate or deactivate Wi-Fi. This single switch controls the radio directly, independent of any saved network list, so toggling it does not remove or forget stored passwords.
If Wi-Fi looks enabled but the phone still will not connect, the issue is usually the network itself or a saved password, not the toggle described here.
