If you’re anything like me, you consider your iPhone or iPad to be the most amazing technology in the world. Until it runs out of juice.
Here are some battery-saving tricks that will help you keep your iPhone running all day long, whether you’re on a tiny iPhone 4s or a massive iPhone 6 Plus. These tips will also help you to get your iPhone to last a little bit longer when you’re away for the weekend without your charging cable.
DIM THE SCREEN BRIGHTNESS OR USE AUTO BRIGHTNESS
This is always the first step when your battery starts to drain. Dim mode uses less power than constantly running your screen at full brightness would.
The screen drains battery faster than anything else and the brighter it is, the faster it drains.
Go to Settings > Display & Brightness and turn Auto Brightness off. Then, set your brightness to the lowest setting that still looks readable. You might have to tweak it from time to time, but you’ll save a lot of juice this way.
KEEP THE SCREEN TIMEOUT SHORT
The less often your phone’s screen is actually turned on, the more battery you’ll save. You can cut down on this by making it so that your phone’s screen shuts off quickly when it’s not in use.
Head to the Settings menu, select General, and then scroll down to Auto-Lock.
Set it as low as you can if you really want to save battery life without it becoming annoying, and you’ll save a decent amount of battery life over time.
Every second counts here, so set your timeout to the shortest available time.
TURN OFF WIRELESS WHEN RECEPTION IS POOR
Pay attention to signal strength. Your phone drains battery trying to maintain a Wi-Fi or data signal, and it uses more battery when the signal is weak. Airplane Mode is a quick and easy solution in areas with poor reception.
Go to Settings and you’ll find your connectivity options for WiFi, Cellular, and Airplane Mode right at the top. You can also open Control Center ( Simply swipe up from the bottom of the screen to display the Control Center) to toggle WiFi, and Airplane mode.
TURN OFF VIBRATION
You really don’t need your iPhone to vibrate. Besides, it will eat up some battery life and it’s probably only necessary when you have your iPhone on silent.
Go to Settings > Sounds to adjust your Vibrate settings. While you’re there, scroll down to the bottom to turn off Keyboard Clicks.
It might surprise you but the volume setting affects battery life too, so if you are playing music or other audio from your phone, turn it down using the volume buttons.
FETCH EMAIL INSTEAD OF PUSHING
To save energy, most phones can be configured to instead check for (or “fetch”) emails on a schedule — say, every 30 minutes — or only when you manually tell your email app to refresh.
Go into Settings > Mail, Contacts, Calendars > Fetch New Data and switch from Push to either Fetch or Manual.
The longer you make the interval, the less battery you’ll be using. With Manual, it will only check for new email when you open the app.
If you have a single email account and you don’t receive much email, you won’t see a real difference in battery usage between push and fetch. But the more accounts you have on your phone, and the more messages and events each of those accounts receives, the more energy your phone will use, as it has to communicate with those account servers continually.
DISABLE UNNECESSARY LOCATION TRACKING
Watch out for apps that track your location. They consume a lot of battery power. Most of the time it is not iOS itself that is causing the iPhone or iPad’s battery to drain quickly, but all the apps that are running on it.
You can disable the app’s ability to track your location by going to Privacy menu and Location Services.
SHUT OFF UNNECESSARY PUSH NOTIFICATIONS
Some apps will send you notifications that you don’t really need. Every message wakes your device for 5 to 10 seconds, and that can add up, if you get a lot of notifications every day.
To disable, open the Settings app, tap Notifications, tap the app name and disable Allow Notifications.
Avoid extreme temperatures. Apple notes that you’ll get the best battery lifewhen you use the phone in temperatures of 62° to 72° Fahrenheit. In cold temperatures, you’ll see much shorter battery life.
If you use your iPad’s power brick, the charger that came with your iPad, to charge your iPhone 6, its battery will fill up faster.
If you have iOS 9 or later installed on your iPhone, then you can take advantage of Apple’s Low Power Mode. The feature will appear automatically at 20% and 10% battery remaining. But you can manually switch it on by going to Settings > Battery and switching on Low Power Mode.
One of the easiest ways to make your battery last longer may surprise you: Install an ad blocker. Of course you need some battery to install!
Pro-tip: A cheap third-party charger could damage your phone. Many chargers — especially budget models sold online or at your local shopping mall kiosk — are poorly made, or use low-quality components. A poorly made charger can not only damage your phone, but could also hurt you by exposing you to dangerous currents. So if you’re replacing your phone’s AC adapter, or buying an extra, stick with a reputable vendor.
BEWARE BATTERY-SAVING MYTHS
Let’s start with one of the worst “tips”: Closing (or force-quitting, as it’s commonly called) apps you are not currently using. Quitting them will not save energy.
Many people recommend disabling Bluetooth on your phone to get better battery life. But Bluetooth was designed from the start to minimize battery usage, and it has only gotten better over time.
If all else fails … consider buying an external battery.
