Battery Saving tips on iOS11

low battery.png

If you just updated to iOS 11 and noticed that your battery life is no longer as good as it used to be, there are a few things you can do to make sure your phone makes it through the day.


It may take a few days for your iPhone to optimize itself to get used to your day to day life. Use your iPhone like you normally do, and allow it a few days to fully reindex and cache everything, and that may just do the trick.

Battery Settings

Under Settings > Battery, you can see all the apps that drain your battery. If you notice apps you do not use in this list, make sure you delete them. For ones that are draining a lot of battery, try changing the settings on them to optimize your battery life. Finally, sometimes, a suggestion will show up on things to try to do to increase the battery life.

Disable Bluetooth

If you don't use bluetooth, disabling it can save you some battery life. New to iOS 11 is that bluetooth does not turn off when disabling through the control panel. It will just show not connected. In order to fully disable it, you will need to disable it in Settings.

Enable Reduce Motion

App launching animations and parallax effects on the home screen can be disabled to save battery life further. Go to Settings > General > Accessibility > Reduce Motion

Location Services

Many of the apps use location services. This can drain the battery tremendously. To access location services, go to Settings > Privacy > Location Services. You can Disable them or set it to While Using.

Disable Auto-Brightness

Auto-brightness is a great feature, but it may amp up the brightness when it is not necessary. It is easy to change the brightness through the control center, so auto-brightness is not needed. To disable it, go to Settings > General > Accessibility > Display Accommodations.

Disable Raise to Wake

Raise to wake is very convenient, but it may cause the iPhone to come to life more often than necessary. To disable, go to Settings  > Display & Brightness.

Disable Notifications

Notifications are useful, but not needed for every app. Every time a notification comes in, it wakes up the phone briefly. To disable, go to Settings > Notifications and disable the apps you do not need notifications from.

Siri Suggestions

Siri suggestions use your location and visited places to provide this feature. This can drain the battery. If you do not use this feature, you can disable it by going to Settings > Siri & Search.

iCloud Backing up your items is important, but it is best to do it when you are at home or somewhere that provides a power source, since some items, like photos, can take a lot of power and time. To change your iCloud settings, select your name in Settings, then iCloud. Disable the things you don't want to store on iCloud.
iTunes & App Store

Downloading is one of the biggest battery drainers on your phone. To keep from using up your data and power, you can go to Settings, select your name, and then iTunes & App store and disable Use Cellular Data and Automatic Downloads.

Fetch New Data
  • Updating your mail, calendar, and iCloud is useful, but you do not have to do it constantly. To adjust the interval, go to Settings > Accounts & passwords > Fetch New Data. Change the interval to something further apart to conserver battery life.
Data being sent to Apple

It is great to send your information to Apple, so they can provide us with the best products, but if you do not wish to do this and conserve battery life, go to Settings > Privacy > Analytics and disable it.


There is no way to turn off advertising, but you can limit it by going to Settings > Privacy > Advertising - Enable Limit ad tracking.

Disable Hand off

Hand off is a nifty feature if you have other Apple products, but if you do not, go to  Settings > General > Handoff and disable it.

Many people have been asking me on how do I maintain good battery health on my iPhone. This is worth reading especially if you're a heavy user of any iOS device.

Before I give the tips, lemme share something first.

I am a huge fan of Apple or any iOS devices. I started using iPhone way back 2007, which is the first flagship device of Apple, the iPhone 2G. Now, I am an iPhone 7 user, using it for almost 2 years but still have 97% of battery health.🤗 (Sorry don't have enough budget to buy iPhone XS max as of the moment😅) But I still have my lower generation iPhones.

Our phones go with us everywhere, even in water. (Nowadays, smartphones have Ingress Protections) So that means we are also consuming our battery's life hardly.

I've been seeing posts and questions with regards to Battery Health of iOS device which they said, was degrading fastly for unknown reason. Lemme correct that, there is a reason why this thing happens.

So here are some tips on how we can prevent that.

*Do not let your phone reach 20%, or lower, or even the first warning for low power mode as it may lead to damaging your battery, causing your battery health to be degraded thoroughly. If you have your charger and a power source with you, charge your phone even if it's still 30% or higher. Charging your phone consecutively ain't bad. In fact, it is a good practice for your battery.😊

*Using your phone while charging ain't bad too. Just make sure, to use "certified/authentic" charger from Apple. If you have some extra budget, I would highly recommend you to buy the 12 watts version of wall charger rather than the 5 watts. I know it is very costly but trust me, it's very worth it. It will charge your phone even faster.

*Just because it is indicated above that your phone is already 100% doesn't mean it is fully charged. The indicator above is just a measure and is not totally accurate. So I would advise to still charge it for 10-15 minutes for a fully charged battery.

*Overcharging is not an issue with the batteries of iPhone because its battery has its own memory, which automatically stops receiving power when fully charged.

*To maximize your phone's battery life:
-Turn off the Background App Refresh
To turn it off, Go to Settings, General, Background App Refresh and turn the toggle off.
-Turn off Hey Siri if it's not necessary.
-Turning off the Wifi and the Bluetooth in the Control Center doesn't mean it is already off. It just disconnects your phone to any connection but still has battery consumption. Always turn it off in the settings.
-Always force close apps after using.
-Do not use Low Power Mode as it will weaken your phone's power resulting for poor performance and slower processes. This will consume more energy.
-Set your phone's auto lock to 1 minute, or 30 seconds to save battery life.
-Buy your own powerbank so you'll never have to worry for getting into low power.
-Restart your phone atleast once or twice a day. This will clean your RAM and improve you phone's performance.
-Turn off raise to wake up.
-Auto brightness is advisable rathen than adjusting it manually.

Edit / Additional

If in any case that you observed that your battery drains too fast even though you still have good battery health, you can perform a "Battery Calibration" in your iOS device atleast once a month.

Below are the instructions on how to do it.

-Drain your battery life to 0% or till your phone automatically shuts off.
-After draining, plug it in a charger. iOS devices will automatically boot up once it has enough charge. When it boots up, turn it off again. Do not enter your passcode or unlock the screen, just turn it off again.
-Leave your phone plugged and turned off while charging for four hours, yes, four hours!
-After charging it for four hours, turn it on. Do not unplugged the charger yet, just go to your home screen.
-Once you're in the home screen, perform a hard restart in your iOS devices. (Kindly look in Google on how to do a hard restart on your device, make sure to search the exact model because it has different procedures)
-Your phone will automatically restart when you perform a hard restart.
-When the hard restart is done, perform a restart again, turn off your iOS device for 10 seconds, after that, turn it back on.
-Once it turns on, you may now unplugged the charger and continue using your device.

Congrats! You're done calibrating it.💖

I've been using iOS 11 for a while now, and I thought I'd share some battery-saving tips that have worked wonders for me. Here are a few things you can try:

  1. Adjust screen brightness: Lowering your screen brightness can significantly extend battery life. Consider enabling auto-brightness or manually setting it to a level that is comfortable for you but not overly bright.

  2. Manage Background App Refresh: Go to Settings > General > Background App Refresh and disable this feature for apps that don't require constant updates. Only allow it for the essential apps you use regularly.

  3. Disable Push Email: If you don't need real-time email notifications, consider switching from push to fetch or manual mode. This reduces the frequency at which your device checks for new emails, ultimately saving battery life.

  4. Limit Location Services: Navigate to Settings > Privacy > Location Services and review which apps have access to your location. Consider disabling it for apps that don't necessarily need this information. You can always enable it on an as-needed basis.

  5. Manage Notifications: Minimize unnecessary notifications by going to Settings > Notifications. Disable notifications for apps that aren't crucial or adjust them to only receive alerts from selected apps.

  6. Optimize Auto-Lock: Set a shorter auto-lock time by going to Settings > Display & Brightness > Auto-Lock. Choosing a shorter duration ensures your device goes into sleep mode more quickly when not in use.

  7. Background Refresh for Wi-Fi Only: Head to Settings > iTunes & App Store and toggle off "Use Cellular Data" under the Background App Refresh section. This way, background app refresh will only occur when you're connected to a Wi-Fi network.

These tips have significantly improved my battery life on iOS 11, and I hope they help you too. Feel free to share any additional tips you may have!

Forum Comment 2: Title: My Battery Life Improved on iOS 11 - Here's What I Did

Hey folks,

I recently upgraded to iOS 11 and was pleasantly surprised by the improved battery life. Here's what I did to make the most of it:

  1. Enable Low Power Mode: When your battery is running low, Low Power Mode can be a lifesaver. It temporarily reduces power consumption by disabling or limiting certain background activities. Just go to Settings > Battery and toggle it on.

  2. Identify Battery-Hungry Apps: In Settings > Battery, you can see which apps consume the most battery. If you notice any apps using an excessive amount of power, consider minimizing their usage or finding alternative options.

  3. Utilize Airplane Mode: When you're in an area with poor cellular reception or don't need connectivity, turning on Airplane Mode can help conserve battery. It disables cellular, Wi-Fi, and Bluetooth connections, reducing power usage.

  4. Avoid Unstable Wi-Fi Networks: Unstable Wi-Fi connections can drain your battery as your device continually tries to connect or reconnect. If you're in an area with weak or unreliable Wi-Fi, it's best to switch to cellular data or disable Wi-Fi temporarily.

  5. Keep Your iOS Up to Date: Apple regularly releases software updates that include optimizations and bug fixes, which can improve battery life. Make sure to install the latest iOS version available for your device.

Remember, these tips might not work the same for everyone, as battery usage can vary depending on individual settings and usage patterns. However, they have been helpful for me, and I hope they prove beneficial for you as well.
