One of the things that most iPhone users pay close attention to is their battery consumption. Apple likes to insinuate all-day battery life for most of its iPhones, but the unfortunate reality is that most activities drain substantially more battery than we’re led to believe, such as online gaming, operating the device in a low signal environment, using the device as a personal hotspot, and so on.
To help combat the issue of a draining battery, some users carry external battery packs or extra charging cables on or about their person to ensure that they’ll always have a way to keep their handset alive throughout a demanding day. But why do that when you can fine tune your handset’s software to keep the battery powering your handset even longer?
