Lifehacker:
Over just a few years, the batteries in our smartphones have changed a lot. That means those old tips to stretch out your battery life just aren’t as true as they once were, yet we still share them like they’re gospel. Before telling someone to disable Bluetooth or Wi-Fi, let’s shed some light on those old myths.
Pass this along to the people in your life who still believe you can overcharge the batteries on laptops or iPhones.
This article is misleading on one count. While WiFi and Bluetooth are no longer the battery killers they once were, cellular data can consume power more rapidly if your phone is in a weak signal zone. In fact, the reduction in battery life is rather significant. While the article does not explicitly say one way or the other when it comes to cellular data, mentioning WiFi and BT but not cell data may lead naive readers (99.9% of people including most programmers) to lump them all together. Then there is additional obfuscation: “Similarly, turning on Airplane Mode, which cuts cellular, Wi-Fi, Bluetooth, GPS, and location services, only squeezed out an extra 30 minutes of life, which isn’t that much all things considered (and this was two years ago, things have likely improved since then).”
Since they insist upon spelling “Macworld” in camel-case, I vote to call them “LifeHacker.”
What about Wave technology? 🙂
