I have a huawei p smart 2018.
Since I've had that, I haven't received any notifications from WhatsApp or Microsoft Teams when I have received a message.
Today I saw that WhatsApp and Teams say "finished" when using the battery.
I suspect that it has something to do with the fact that I don't get any notifications, because Telegram says "active" and I always get a notification.
I would be very grateful if someone would answer me.
Maybe you activated the energy saving mode.
No, and I also switched off energy saving mode
Could be the impact of US sanctions against Huawei. US companies are no longer allowed to work with them.
Telegram belongs to a Russian oligarch who doesn't even care what Putin is asking of him…
Android has a battery optimization. Go to Settings and Programs, find the respective program and deactivate the battery optimization / energy saving optimization there.
I've done it before, but thanks anyway😊
