Click the links above to jump to a specific section, or continue scrolling to learn how to save your iPhone battery life.
1. Location Services
We all know GPS can drain your iPhone battery real quick. So does Location Services, since it uses GPS, Bluetooth, and crowd-sourced Wi-Fi hotspot and cell tower locations to determine your location. That is really a heavy lifting for your iPhone battery.
Locations Services is a great feature and for some is a life-save feature. I use it all the time to get around. So we’re not telling you to turn it off completely. You’ll only turn off the unnecessary ones.
Go to your iPhone Settings > Privacy > Location Services. You’ll see a list of all the apps that have access to your location and how they track you. Take your time to grant access to apps that really need your location to work properly.
Third-party apps are the ones that always need access to your location even they don’t really need it. Most of the time they’ll abuse and misuse your location. So keep an eye on them.
Scroll all the way down and select System Services. You’ll see a list of options that are probably all on by default. You might think, if they’re on is for a reason, and you shouldn’t turn them off.
Do not panic, you can safely turn them off. It won’t affect your iPhone functionality. Apple is only collecting all this data for marketing and research purposes, so it can improve its products in a future release.
Just turn off everything except Find My iPhone (in case it get lost), Emergency SOS (in case you’re in danger), Motion Calibration & Distance (fitness activities). Those are the options I think most people should have on, but it’s totally up to you. At the end of the day, it will save you battery.
Status Bar Icon: It’s up to you to leave that on or off. It only lets you know if your location is being used. For some, it might be useful but could impact your battery performance.
Notifications are great, they send you alerts about what’s going on. But at a cost, they’re power-hungry. I only leave the important ones. I know people who allow Push Notifications for every single app on their phones. No wonder why their phone battery drains so quick.
It’s kind of annoying to have your phone waking up all the time to show off notifications. Go to Settings > Notifications you’ll see a list of all your apps on your iPhone. Go through them and check if you really need those apps to send you alerts.
To turn them off, tap on the name of the app and toggle off the switch next to “Allow Notifications”. The fewer notifications you receive, the longer battery life you’ll get. Depending on your iOS version, you may see some governments alert at the very bottom, I’d suggest you leave those on for your own safety.
3. Push Email
Push Email is a perpetual battery drain if it’s not the absolute worst. The Email app, when it’s not set to “Manually”, will refresh itself constantly to pull off new emails from the email server as they come in.
I set all my accounts to receive updates manually for better battery life. You can do that by heading to Settings > Passwords & Accounts > Fetch New Data and switch off the toggle next to Push.
Tap on each account and set the schedule to “Fetch”. Now it’s up to you if you want to fetch manually (every time you open the app) or every certain period of time (Hourly, Every 30, 15 Minutes). You decide what’s best for you.
4. Signal Reception
Have you ever noticed your iPhone’s battery drain faster in places with poor reception? Yes, and it’s no coincidence. That happened to me at least once.
I was on my way to New Jersey, with my iPhone fully charged. It was a brand new iPhone, so the battery was in good shape. But surprisingly, my battery life went down to 36% with minimal use in just 4 hours.
In areas of poor reception, your iPhone or any phone will constantly check for a stronger signal. And that drains the battery must faster than anything. There’s not much you can do about other than putting your phone on Airplane mode.
5. Low Power Mode
Apple introduced iOS 9 with a new feature called Low Power Mode, which reduces power consumption and makes your battery lasts longer.
You have to enable it since it’s not set up by default. Head to Settings > Battery and toggle the switch to ON next to Low Power Mode.
If your battery hits 20%, a message will automatically pop up on your screen offering to turn Low Power Mode on. If you do so, the battery will turn orange, which shows Lower Power Mode is on. Once you charge your battery and it reaches 80% or higher, Low Power Mode will switch off.
It’s important to note when your iPhone is on “Low Power” Mode some features may not work. These are the ones that are affected:
Background app refresh
iCloud Photo Library
Some visual effects
6. Visual Effects / Background App Refresh
The Visual Effects first introduced in iOS 7 are marvelous, but at a cost, they’re power-hungry. They constantly use your iPhone’s graphics processor to give you those pretty Parallax effects.
When Background App Refresh is on, it allows certain apps to download contents, and refresh themselves even when you’re not using them. By disabling it, you can save a good amount of battery life
Those features not only drain your battery life fast but can also slow down your iPhone performance. You can see our guide on how to speed up iPhone for details instructions.
To turn off Visual Effects, Go to Settings > General > Accessibility > Reduce Motion and toggle the switch to turn it on.
To disable Background App Refresh, Go to Settings > General > Background App Refresh. You’ll see a toggle at the upper right corner of the screen where you can turn off the feature entirely. I would not recommend you to do this since it can be vital for certain apps.
You can leave it on, and scroll down through each app to turn off the ones you think it’s necessary.
The chances for iPhone users to use widgets are very low. If you happen to use them, you should know these widgets consume a lot of power. They continually run in the background to give you timely information from your favorites apps.
If you are someone that doesn’t use them, you can feel free to turn them off. To access Widgets, go to your iPhone Home screen, swipe to the right, then scroll down and tap on Edit.
You’ll see a list of the widgets. To remove a widget, tap on the red minus icon on its left, and you’re set. You should save a considerable amount of battery life by turning them off.
8. Bluetooth / Wi-Fi
Many people recommend turning off Bluetooth and WiFi to get better battery life. It’s a myth, and there’s no reason to believe so. Bluetooth and Wi-Fi use no energy unless they’re connected to a device. And when they are, they use very little of your battery.
Look, if your battery is running low, using Bluetooth headphones for streaming music for long periods of time, is definitely not a good idea. I would suggest you use wired headphones instead.
In iOS 11, Bluetooth and Wi-Fi always stay on so you can use some important features like AirDrop, Apple Watch, etc. Even though you don’t use those features at all, it’s important to not turn them off. They’re critical for assisted GPS (aGPS) (when you can’t receive GPS satellite signals) and to help you back up your iPhone to iCloud.
9. Power-hungry Apps
Some apps use way more power than others. So it might be a good time to check what apps are sucking up your battery juice. Go your iPhone Settings, scroll down and find Battery, then tap on it.
You’ll see a list of apps with details on battery usage for the last 24 hours and 7 days, with the heaviest battery-hoggers at the top of the list.
Now, it’s up to you if you want to delete those who consume more battery life or reduce how much time you spend on them. The latter option seems more doable since Apple introduced a new tool in iOS 12 to help you fight iPhone addiction.
10. Close out Apps
This one is controversial and there’s a myth behind it. Many people believe running apps in the background drain battery quick.
Apple Senior Vice President of Software Engineering Craig Federighi put that myth to rest by responding to an email a customer sent to CEO Tim Cook. According to his answer closing out running apps doesn’t save battery life.
iPhone apps crash more frequently now than you think. You can check the crash logs in Settings > Privacy > Analytics > Analytics Data. Sometimes apps will crash in the background and drain the battery life quickly without you even knowing it.
11. App Suggestions
If you pull down on your iPhone screen, you may see some apps waiting for you at the bottom of the search bar, that’s Siri App Suggestions.
Some people may not even aware of it, but it can be very handy as it suggests you apps that you use frequently. Have you ever used it? If not, it’s time to turn it off because it’s draining your iPhone battery.
From your Home screen, swipe to the right to get access to Widgets. Scroll to the bottom and Edit. Look for Siri App Suggestions, tap on the red minus icon next to it, then tap remove.
12. iPhone Analytics (Diagnostics & Usage Data)
During your iPhone setup, you may have chosen to send diagnostics data to Apple and developers. It’s a good thing, you’re sending to Apple anonymous information about how your iPhone works to help the company improve its products.
But there’s a catch. It sucks battery life when your iPhone automatically send data to Apple. To stop sending iPhone analytics, head to Settings > Privacy, scroll to the bottom and open Analytics. Toggle off the sliders next to Share iPhone Analytics and Share iCloud Analytics.
13. Screen Brightness
Displays normally draw a lot of power, and for mobile phones that rely on the battery can be a bad thing. Some may consume more than others depending on what kind of display your iPhone has. OLED displays are more power-efficient than LCD ones.
Even though Apple started to use OLED display in its bezel-less iPhone X, you can still do some tweaks to improve battery life. The brighter is the screen the more power it consumes. The iPhone has an ambient light sensor that determines how much light is around your iPhone and automatically adjusts the brightness of the screen.
From Control Panel, you can use the slider to reduce your screen’s brightness. You can also enable Auto-Brightness, which will do the job for you. Go to Settings > General > Accessibility > Display Accommodations.
14. Siri and Search
Do you rely on Siri to get stuff done with your iPhone? If not, it’s time to turn it off. Like every app, the more you use them, the more battery they consume power.
But I don’t use Siri, how does it drain my battery? Even though you don’t use Siri at all, “Hey Siri” is listening all the time so he/she can respond to your commands. And, that drains the battery.
Go to your iPhone Settings, scroll down and find Siri and Search, tap on it. Toggle off all three button shown in the image above.
Siri Suggestions can be a battery drainer too. Siri analyzes how you use your Apple device to give you personalized suggestions and better search. In order to do that, Siri needs to send some of this information back to Apple.
While you’re in Settings, find Siri Suggestions under Siri and Search and toggles the “Suggestions in Search” and “Suggestions in Look Up” switches to off.
You can also prevent apps from helping to personalize Siri. Scroll down to find the app you want to disable, select it and slide the “Search and Siri Suggestions” switch to off.
15. Extended life battery
If you want longer battery life but don’t want to turn off those features, your best options are to invest in an iPhone extended life battery case or an external iPhone battery charger.
Accessory maker like Mophie makes good battery cases that can easily double your iPhone battery life. Feel free to check out their website.
16. Turn Off Personal Hotspot
Personal Hotspot is a feature that I use all the time with my Mac, especially when I’m on those long commutes. While it’s nice to turn your iPhone into a wireless hotspot, it also can drain your battery fast.
It’s recommended to turn it off if you’re not using it. Here’s how to turn Personal Hotspot off:
Go to your iPhone settings
Tap Personal Hotspot
Toggle off the slider on the right
17. Hardware Problem
Most of the time your iPhone battery problem will come from software issues, but sometimes it can be hardware issues too. If it’s the case, it’s time for you to change the battery.
