If your iPhone’s battery is draining faster than you'd like, I totally get how annoying that can be. There’s no magical fix-all, but there are definitely a few things you can try that, when combined, usually make a big difference.
First off, if you’ve recently updated your iPhone, sometimes a new iOS update can cause a temporary spike in battery usage. Right after the update, your phone is busy in the background reindexing files, photos, apps, and whatnot. So if this started happening after an update, give it a couple of days and see if things settle down.
Now, let’s talk about background activity. A lot of apps run in the background, using up juice even when you’re not actively using them. You can go into your settings and take a look at Battery Usage to see which apps are the worst culprits. If you notice certain apps using way more battery than they should, you can go into Settings, and tweak things like Background App Refresh or Location Services to prevent them from running when they don’t need to. It’s worth turning off background refresh for apps that you don’t need constantly updating.
Screen brightness is another sneaky battery drainer. If you have your screen set to maximum brightness all the time, it’s going to burn through your battery. Try setting your phone to auto-brightness, which adjusts the screen based on the lighting conditions around you, or just manually lower it. It might seem small, but over time, it makes a big difference.
