@lukaszsas23Nawet w instrukcji obsługi nie ma o tym wzmianki, jednak znalazłem w sieci coś takiego:
"Basically, Power Saving Mode analyses patterns in Wi-Fi traffic, and adjusts the wireless connection accordingly. For example, if your email app retrieves e-mail every 15 minutes, the Power Saving Mode recognises this. it then knows that the connections is only needed at this particular interval.
it does this for all your apps, analysing and learning the connection behaviour, and adjusts the Wi-Fi connection accordingly. Which in turn saves you power. And in theory, you shouldn't be affected by loss of connection.
But really, Wi-Fi doesn't use much power at all, and to me, it's just not worth it having it enabled, as it can cause bandwith and speed issues on the odd occasion."
Opcja ta jest dostępna co najmniej od S8
