Complete instructions for iOS 9: How to increase iPhone battery life

With the arrival iOS 9 promised Apple also improving the battery life of our iOS  device thanks to new features that are supposed to prevent frequent screen activation and the like. Unfortunately, some users still did not notice a noticeable improvement in battery life. Fortunately, as in every version iOS, as well as in iOS 9, you can make changes in Settings in a few moments that can significantly affect the overall battery life of your iPhone or iPad throughout the day. There are several of them, and therefore, by combining them together, we can achieve a fairly good result, which can easily achieve an improvement of several hours. ProSo let's dive into them and find out how to increase the battery life of your iPhone or iPad with iOS 9.

Battery usage
On your iPhone, you can check which apps drain your battery the most. Just go to Settings -> Battery and here you will see how much percentage each application has taken either in the last 24 hours or 7 days at the time it was iPhone is not charging and since it was last charged to 100%. Pro For more detailed information, just click on the clock icon and you will see the exact time, how many minutes the application has been working on the screen and how many in the background.

You can also check here when your iPhone almost dead and check how many hours it has lasted since the last charge, and how many hours you have actively used it. If an application that you are not even using is unnecessarily consuming energy, simply delete it.

multitasking
The aforementioned battery usage can very easily show you which apps you should turn off in the app switcher or in the multitasking that you bring up with a double click. Home buttons. Of course, do not turn off applications that you often reopen, as this will only drain the device and each application launch will be slower. However, applications such as Maps, navigation, Apple Music, Spotify or VoIP apps should always be turned off if you already know you won't need them.

Background app updates
Perhaps the most important point is background application updates. As the name suggests, if you're not using one of your apps right now, it doesn't mean it's not draining your battery, the app updates in the background and therefore consumes a fraction of some power. So limit background updates in Settings -> In general -> Background app updates by turning off updates for any apps you don't use or don't really need. The entire service can also be turned off. However, if you turn it off, system apps like Messages will still update in the background.

Location services
V Settings -> Privacy -> Location services you can turn off location detection for all apps that have requested access to this feature. You can either turn off location services completely, which will turn them off for the system as a whole and thus achieve a much better result, or here you can turn off location determination only for some applications. The middle way is the option that applications will use location services only when they are active, but this option is not available for all applications.

Frequented places
The above location services settings are closely related to disabling the detection of frequently visited places. In Settings -> Privacy -> Location services -> System services -> Frequented places you can turn this option off and iPhone This way, it won't detect where you frequently move and use location services unnecessarily, thus consuming precious energy.

Spotlight
Latest iOS 9 came with one half-useful and half-useless new feature. It now allows you to view all applications using Spotlight, including those installed from within the system. App Store. ProThe problem is that in order to be able to quickly search for everything in Spotlight, you have to iPhone it has to map everything first, which it does regularly. In most cases, you don't need to search directly within applications, and Spotlight is only useful for quickly finding contacts, for example. That's why you can Settings -> In general -> Search in Spotlight turn off all applications that you don't want Spotlight to search in and map them unnecessarily on a regular basis. Switching off will have a significant effect on the overall speed of the system on older devices

App Store
V Settings -> iTunes and App Store you can disable the automatic download of Music, Applications, Books and especially Updates. This means that, for example, updates for applications that you have downloaded do not start downloading automatically, but wait for you to do so.

Mobile data and notifications for apps
V Settings At the very bottom is a list of all the applications you have installed on your mobile phone from App Store. For individual apps, you can adjust whether they will use your location and when, whether they will update in the background, where they will have access, whether they will display notifications and what kind, and whether they will use mobile data. You can disable or enable all of this for each app. I recommend disabling the use of mobile data in particular for apps that do not need it. This saves not only your battery, but also partly your FUP. You will only be able to disable or enable the use of mobile data if you currently have it turned on on your iPhone. Limiting notifications can also help to achieve greater battery life. If apps are constantly notifying you, they will constantly wake up the display when your phone is turned off, and this will affect your battery life.

sheepfold
Another big drain on your precious battery is certainly the display and especially its backlight. Battery life is often significantly affected by whether you have automatic brightness set or not. How many times do you iPhone will set the brightness much higher than you need at that moment, so it is better to set the brightness manually and keep it at lower values. It is the manual brightness control instead of the automatic one that has a significant impact on battery life. You can turn off the automatic brightness in Settings -> Display and brightness. It is certainly best to edit it quickly via the Control Center, which you can slide out from the bottom of the screen wherever you want.

Wallpapers
V Settings -> Definitely choose wallpaper classic wallpaper instead of dynamic. Classic wallpaper is more economical than dynamic wallpaper. In addition, if you really want to save battery, then when setting the classic wallpaper, choose only Image instead of Perspective. This is how you deactivate it parallax an effect that also contributes to faster battery drain.

Fitness tracking
Newer iPhones (5s and higher) have already received a new function, Fitness Tracking. However, most people don't use it and use the battery unnecessarily, so we can turn it off. Go to Settings –> Privacy –> Movement and fitness and turn off here Fitness tracking. More about this feature here.

Lockout
V Settings -> In general -> Lockout you can now iOS 9 you can even choose 30 seconds after which the iPhone display will turn off. Originally, it was possible to set at least 1 minute, but thanks to the new feature, you will save even more battery. However, if it often happens to you that the display goes out at the wrong moment and you have to turn it on again, then it is better to choose a longer time interval, because constantly turning on the display is even worse than if the display is lit for half a minute longer.

"Pick Up" vs "Push"
Of course, frequent synchronization of mail, calendars, contacts, notes, reminders, etc. is responsible for draining the battery. Just in Settings –> Mail, Contacts, Calendars –> Data retrieval and here you can choose to select either fetch, push or manual for individual accounts. At the top you can then turn off push completely and at the bottom set the fetch interval to 15, 30 or 60 minutes. You can also use manual fetch, which is economical but inconvenient, as the data is only refreshed when you use the given application, so you will only receive new emails when you open the Mail application, etc.
