If you find your smart phone needs recharging even before the close of business each day, try dumbing down.
The battery will last so much longer if you uninstall Facebook, Facebook Messenger, Twitter, Whatsapp, Instagram, and disable notifications and disconnect email accounts etc etc etc.
Of course, the phone will be ever so slightly less useful…but…guess what?
You can still use it to make and receive phone calls and send and receive texts…and seriously, what more do you actually need from a phone? Err…
