This article is a product of my years of research and anecdotal evidence I gathered in the hundreds of Genius Bar appointments I took during my time as a Genius and iOS technician, as well as testing on my personal devices and the devices of my friends. …
This is not one of those “Turn off every useful feature of iOS” posts that grinds my gears. My goal is to deliver practical steps to truly solve your iOS battery woes.
Great tips. The low-reception-areas tip is especially good — I learned that many years ago when we’d travel to very rural places in upstate New York.
Last time I flew cross-country, the two passengers next to me both left their iPhones in fully-on normal mode. I put mine in airplane mode.1 All three of us used our phones periodically during the flight. When we landed, their batteries were both nearly dead (which they loudly complained about for 20 minutes) and mine was still over 70% charged.
Now that so many flights have Wi-Fi, does it really make sense to name a feature “airplane mode” that turns off all radios? Even though you can turn on Wi-Fi and Bluetooth in airplane mode, as Scotty writes, most people don’t know that.
Maybe modern airplane modes should turn off only the cellular radio, leaving you to disable Wi-Fi and Bluetooth separately if you wish. The toggles are all right next to each other on most smartphones anyway. ↩︎
