I agree with , I only have Samsung galaxy phones and upto now every phone I have had has been superb , apart for the Samsung A22 , its rubbish it clicks off , goes to different pages , n just flickers most of the time ,
Battery draining is faster if signal is weaker. These connection issues many are having is down to Google and Android. The Pixels suffered a huge disconnected issue this year from several bad firmware updates and subsequently this dribbled into other OEM devices. Google has fixed this issue but the fix needs to filter down. Have you asked your network to send you their APN settings etc via text which you can open and it configures your phone automatically?
