What can be the reason that an iPhone SE 3rd gen. loses battery power significantly over night when it is completely shut down? The flight mode was activated before the shutdown. The device is brand new, battery capacity and health is on 100%, no background tasks are allowed. It is a replacement for the same model, which had the exact problem some weeks ago.
I also experience a slight lag while typing on my iPhone. It was definitely smoother before the upgrade. Dictation is normal on the iPhone, though. When I switch to English everything is fine. I guess it has something to do with the new auto correction, although this is said not to be active for German, yet. The voice dictation lag is also there for French. Only English is quick and smooth.
