I am currently using an Oppo Reno 5G phone and noticed data usage is quite high.
Is this because of the screen resolution? I remember using an old Huawei Y5 2017 model used much less data in comparison. I have been watching YouTube in 240p to save data but my wife uses Facebook and Tik Tok a lot to watch videos. You can't change the resolution as far as I know in these apps.
Just for money saving purposes would it be worthwhile to buy another Huawei Y5 to save data again for basic everyday use?
