Why Instagram, Facebook and WhatsApp work so much in the background? I have disabled app background refresh,
Not surprising they are all Meta apps and you would have to ask them why they are consuming so much of your battery. Turning off Background App Refresh is only to prevent UI updates for apps in the background, they are still running background processes that consume your battery even when the apps are not being used.
Meta allows you to use their apps for free and that means you are the product they are selling to generate the billions of dollars every quarter. It was actually $2.71 billion dollars last quarter. The amount of information that they are gathering from you does take power on your device and that data is sold to advertisers for income. Just take Instagram for example and look in the App Store what data they are using, and multiply that by 3 to account for their other apps on your device:
- Contact Info
- Health & Fitness
- Financial Info
- User Content
- Browsing History
- Usage Data
- Purchases
- Location
- Search History
Just do a simple test and remove those 3 apps and compare your Battery usage. You will be amazed. Apple gives you the tools to see the apps that are consuming your battery, and it is up to you if you want to use them or not. If you do not like the way an app performs on your iPhone, the developer of the app is the one who could provide an update to resolve the problem. Even Google has called out Meta for draining the battery on their Android phones, so it is not specific to Apple, and you will see the same reports in the Samsung/Android Support Sites too.
