What general ideas and alternative apps are good to keep in mind to reduce usage of mobile data?
Thanks to @Chelle many of us use Facebook Lite instead of the bloated regular Facebook app. And instead of browsing the web with Chrome or Firefox we use Opera Mini and Puffin. Between Opera Mini and Puffin, which is better at using less data?
What other apps are worthwhile using towards achieving the goal of minimizing data usage? What other user behaviors can reduce data usage? If you use Chrome or Firefox when on WiFi, does leaving it open in the background when on mobile data even without using it, leak data usage? Do other apps leak data while open in the background?
Opera Max, another @Chelle recommended app, is certainly very helpful in data reduction goals, but I've found sometimes it freezes up my data connection and I cannot use the internet until I restart Opera Max. Anyone else experience such behavior? Is using Opera Max to block certain apps from accessing data more effective than blocking said apps directly in the Android settings?
I've noticed some apps that I rarely use, but need installed for the few occasions it's needed, leak small amounts of mobile data consistently. Is there any way to granularly control them?
