iOS 7.1 came out recently and brought with it a bevy of design tweaks and performance enhancements. However, some users are reporting poor battery life since the update, and many blogs are reporting it as fact. (Users will report poor battery life after every iOS update. Always. For eternity. This is not newsworthy.)
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.
One quick thing before we start — 99.9% of the time it is not actually iOS that is causing your battery to drain quickly. I guarantee you that if you erased your phone and there were no apps or email on it, it would last for ages. But, no one uses their device like that, nor should they. Hopefully with these steps you will be living in iOS battery bliss while still using all the apps and features you love.
But first, we need to test and see if you even have a problem to begin with.
If you have an iPhone, you’d be a fool not to read this article.
