Yes in fact the 43 days is in stanby but I don't use the phone for anything else, so I thought it would take more than a few hours between charges. I thought that the difference in battery time between old and new mobile phones was due to the touch screen, but now I don't know to what extent 4G contributes to that difference.

Does "internet sharing" not imply turning on WiFi as well, which usually goes to sleep during standby
