Take some time to follow these steps and enjoy increased battery life.
Apple has been making tremendous improvements to battery life in recent years, but every now and then, I notice that my iPhone battery drains faster than normal. I’m in the habit of plugging my iPhone in every night and in exchange I expect to get a full day of use out of my iPhone.
When I don't make it through the day, it seems to happen when I don't have access to an outlet or I've forgotten my charger.
You should be able to get up to 10 hours of talk time on your iPhone, and up to 250 hours of standby time before needing to recharge. Of course this depends upon the age of your iPhone, your settings and how much activity you do in a typical day.
If you’re having trouble getting a full day of battery life out of your phone, try these suggestions to help improve your battery life:
1 - Set your email to fetch every 15 minutes
When "Push" is enabled for your email, it means your phone has a constant connection to your email server, constantly checking to see if you have new mail. This constant checking can drain your battery.
Switch your mail settings to ‘Fetch’ will check for new mail in the timeframe you select. Setting this timeframe to every 15 minutes will save battery life.
If you open your Mail app, it will check for new mail right away. If you’re sending a message, it will be sent right away.
Here’s how to change your Fetch New Data settings:
Go to Settings -> Mail, Contacts, Calendars -> Fetch New Data and turn off Push.
Set each individual account to Fetch.
Select the timeframe of Every 15 Minutes to save battery life.
2 - Review Location Services
The location services feature on your iPhone uses GPS, Bluetooth, cellular towers and available wi-fi hotspots to detect your location. If this feature is enabled, your iPhone can be constantly trying to determine your location, using up your battery.
This feature is essential for some apps that are providing driving directions, like Google Maps or Yelp. It is also essential for some system features like Find My iPhone. However, it may be unknowingly enabled for some apps you don’t care about.
Here’s how to review location services:
Go to Settings > Privacy > Location Services
- Location Services; keep this turned on and control which apps use location services.
- Share My Location; allows people to see your location in iMessage and Find My Friends. If you don’t use this feature, turn it off.
- Review apps; if using the app for location, set to ‘while using’, otherwise set to ‘never’.
- System Services; turn off these location services which are unnecessary for most people:
- Location-Based Alerts
- Location-Based iAds
- Spotlight Suggestions
- Wi-Fi Networking
- Frequent Locations; allows your iPhone to learn places you visit frequently.
- Product Improvement; sends information to Apple to improve products.
- Diagnostics & Usage
- Popular Near Me
- Routing and Traffic
3 - Turn Off Diagnostics & Usage and Suggested Apps
The diagnostic and usage feature is enabled on your iPhone by default. It sends data to Apple to help them gather information about issues with iOS and usage. This can contribute to battery draining and Apple can find another way to gather information.
Here’s how to turn off Diagnostics & Usage:
Go to Settings > Privacy > and scroll all the way to the bottom of the screen. Select Diagnostics & Usage and select Don’t Send.
This is another location-based feature that recommends App Store apps based on your location. For example, if you’re at Starbucks, the App Store may recommend that you download the Starbucks app. It may be useful to you, but since it uses location services, it can contribute to battery drain.
Here’s how to turn off Suggested Apps:
Go to Settings > General > Handoff & Suggested Apps and turn off My Apps and App Store
4 - Review Notifications
You’ve seen this message before, usually right after installing a new app. But what exactly are you agreeing to?
When you allow an app to send you Push Notifications, you’re giving that app permission to keep running in the background so that if something happens (like you receive a message or you entered a Starbucks reward), the app will wake up your phone to let you know.
Notifications can be a good thing, but they do drain battery life, so it’s important to only use the ones you need. You can easily change the status of notifications, so when I see the message, I usually select ‘Don’t Allow’.
Here’s how to review Notifications:
Go to Settings > Notifications
- Include section; shows the apps that have notifications turned on. If you see an app here that you don’t need to alert you, turn it off.
- Do Not Include section; shows the apps that have notifications turned off. To allow notifications, turn it on.
- Government Alerts; shows AMBER alerts and emergency alerts. I leave these on.
5 - Review Background App Refresh
Apple has a feature called multitasking, which allows apps to perform certain tasks in the background while you're using other apps or not using your device. Because of multitasking, you can switch quickly between apps and see updated data when you open or return to your apps.
All apps refresh data when opened. If you use an app frequently you may not want to wait for data to refresh, so keep background app refresh turned on. Turning off this setting for apps you use infrequently will save battery life.
Here’s how to change Background App Refresh:
Go to Settings -> General -> Background App Refresh
You can turn it off for all apps, or select specific apps
6 - Dim the Screen or Turn on Auto-Brightness
The brightness of your screen has an impact on battery life. You can manually dim the screen or turn on auto brightness, which uses the ambient light sensor right above the earpiece of your iPhone to adjust the brightness based on the amount of light around you.
Here’s how to dim your screen:
Swipe up from the bottom of any screen to open Control Center and drag the Brightness slider left.
Here’s how to adjust Auto-Brightness:
Go to Settings > Display & Brightness and turn Auto-Brightness on.
7 - Decrease Your Lock Time
Whenever your iPhone is illuminated, it is impacting battery life. Setting the auto-lock feature to a shorter period of time will lock the phone and turn off the display sooner.
Here’s how to adjust your lock time:
Go to Settings > General > Auto-Lock > choose 1 or 2 minutes
8 - Use Wi-Fi when possible
When you use your device to access data, a Wi-Fi connection uses less power than a cellular network — so keep Wi-Fi on at all times.
Here are two ways to turn on Wi-Fi:
Swipe up to open Control Center, tap the Wi-Fi icon, and log in to a Wi-Fi network.
Go to Settings > Wi-Fi to access a Wi-Fi network.
9 - Turn on Airplane Mode When No Cell Coverage or Low Signal
If you’re in an area where there is no cellular coverage or the signal is weak, your iPhone will continually search for a signal, causing your battery to drain. To save your battery in this situation, put your iPhone in Airplane mode.
Here are two ways to turn on Airplane Mode:
Swipe up to open Control Center, tap the airplane icon.
Go to Settings > Airplane Mode and turn it on.
You won't be able to send or receive phone calls, emails or text messages, but you will preserve your battery.
10 - Avoid extreme temperatures
According to Apple, your device is designed to perform well in a wide range of temperatures, with 62° to 72° F (16° to 22° C) as the ideal comfort zone. Exposing your iPhone battery to temperatures above 95° F (35° C) can permanently damage your battery.
It’s even more harmful if you charge your iPhone in high temperatures. Even storing your iPhone in high temperatures can decrease your battery life forever.
When using your iPhone in a very cold environment, you may notice a decrease in battery life, but this condition is temporary. When your iPhone warms up, your battery should be right back to normal.
Following these suggestions will likely improve your battery life. For a more in depth review of your battery usage, iOS8 tracks the details about battery usage.
