>Is this the reason that my old mid/low end android devices become unusable even through they no longer get updates? More recent versions of apps (like whatsapp, which requires to be updated regularly) are unnecessarily more demanding. Try disabling Play services, all Bloatware, all quasi-bloatware (calendar, contacts), all the way to the default keyboard. (pm disable-user --user 0) Install FOS replacements with no internet connectivity, e.g. from f-droid and such (not affiliated) It is easier to buy a new device, but I get attached to my pal ;)
