3 Communication Apps

Most communication apps can end up draining your battery, which is largely due to the fact that they always search for new content in the background. For the purposes of this piece, we’ll focus on two: Skype and Mail.
You’ll want to turn off Background App Refresh for apps like Skype, which is notoriously bad for iPhone battery life. Of course, this negates some of the convenience of that app — which is why switching to FaceTime may be a good idea.
Even first-party communication services, like Mail, can drain your battery. But there’s an easy way to mitigate it. Just go to Settings > Mail > Accounts > Fetch New Data. Fetch will eat up battery life, so set it to a longer time interval to decrease battery drainage.
