3. Check your charger

Unfortunately, with the iPhone 12 lineup, Apple has decided not to include a power adapter (and wired earpods) with any of its iPhone. Apple has said this move is to reduce its carbon footprint on the environment. Therefore, you’ll have to buy a power adapter separately, as you would get only a USB-C to Lightning cable in the box. 

Now, if you’re using a charger that’s lying in your drawer or have got a new power adapter, make sure it’s either official or MFi (Made for iPhone, iPad, and iPod) certified. Using non-MFi certified accessories with your iPhone can cause battery related problems on your device. Plus, you may face an abnormal battery drain on your iPhone 12 if you’re using incompatible or cheap third-party charging accessories. This is one of the most easily overlooked reasons why you’re facing battery-related problems on your IPhone 12, 12 Mini, 12 Pro, or 12 Pro Max. 

Here are a few tips that you must follow to check if you’re using an appropriate charger:

1. You must use the official charger (we’re talking about both, adapter and cable) that came with your phone or the one that you bought from the Apple store or some reliable third-party resellers.
2. You must also check your charging cable for visible signs of damage like bends, exposed wires, or breakage. If your cable turns out to be damaged, use a different cable (if you’ve got any) or get yourself a new one. 
3. Also, when we’re talking about checking your charging cables, it’s worth mentioning that a cable can have some internal damage that’s not visible. Therefore, if any of your family members has got an iPhone and their charger is working perfectly fine, you must try charging your phone with that charger. If you’re able to do so, it’s time to replace those faulty charging accessories.

4. Disable background app refresh

There’s a Background App Refresh feature on iPhone that allows various apps on your device to fetch content in the background. This ensures that the app content and notifications are always up to date. Talking about the advantages the Background App Refresh feature minimizes the lag time in displaying the updated data when you launch an app. However, this feature also consumes a considerable amount of power on your iPhone. 

Therefore, if your iPhone 12/12 Mini battery drains faster or if you notice an abnormal battery drain overnight, you must disable Background App Refresh, and see the difference yourself. 

For this, go to Settings > General > Background App Refresh, and select OFF. 

Therefore, it’s a good idea to disable Background App Refresh for all the other apps that need not be updated all the time. Also, social media apps like

Instagram, FaceBook, and others can have a huge impact on the battery life of your phone. Therefore, if you want to fix iPhone 12 overnight battery drain problems, make sure to disable Background App Refresh for all social media and eCommerce apps.

There can be instances when you want to enable Background App Refresh for some apps like  Google Drive, Dropbox, Google Photos, OneDrive, or any other app where you constantly upload media in the background, you can select the upload only on Wi-Fi option. This can help you save battery to some extent. 

5. Turn OFF Auto-brightness

Do you keep your iPhone at the brightest possible display while playing games or watching Netflix? If so, you must know that this is one of the prime reasons for a faster battery drain on your iPhone 12, 12 Pro, 12 Pro Max, and even the smallest phone in the bunch, the iPhone 12 Mini. The brighter the display, the more power it consumes. An overly bright display may look stunning, but it’s not at all good for the battery life of any smartphone. Besides, if you keep the brightness too high for a long time it can also lead to other problems like

overheating issues.

When you’re indoors, it’s good to turn OFF auto-brightness on your iPhone. For this, Settings > Display & Brightness > Turn the slider OFF for Automatic.

For adjusting the brightness automatically on your iPhone 12, go to the Control Center and adjust the slider for the screen brightness (sun-shaped icon). You can also go to Settings > Display & Brightness and drag the slider to adjust the brightness. 

We’re not asking you to stick to a very dim display as it can have an adverse impact on your eyes. You can switch to a lower brightness level that you’re comfortable with. If you keep the screen brightness somewhere around 40-60 percent in ambient lighting, you’re sorted.

6. Turn OFF Raise to Wake and adjust Auto-lock

The Raise to Wake feature automatically turns ON your iPhone’s display every time you pick up your phone and it’s facing towards you. Therefore, you can check notifications, time, or any other info, without using the power button.

However, there’s a disadvantage too. It can consume the battery unnecessarily on your iPhone. When you’ve got your iPhone in your hand, and you’re walking, the display can turn ON automatically, and drain the battery. Though it doesn’t make a huge impact, if you’re facing excessive battery drain issues on your iPhone 12 Mini, 12, 12 Pro, or 12 Pro Max, you must put together all the little steps that can make a huge difference.

Turn OFF raise to Wake to save some battery on your iPhone. Head to Settings > Display & Brightness > Raise to Wake > Toggle Off.

Let’s talk about another important thing here. We all have a habit of checking our phones for about a minimum of 40-50 times a day, just to see the time, notifications, or any other info. And, here comes an important thing to notice. After you’ve checked your phone and put it down, the display stays ON for 1, 2, or even 5 minutes until the screen turns off by itself. This draws a lot of power. It is known as the Auto-lock feature in the iPhone, and if configured properly, it can help you save a lot of battery on your phone. To fix iPhone 12 faster battery drain or get rid of iPhone 12 overnight battery drain problems, adjust the Auto-lock to 30 seconds on your iPhone. 

7. Use Low Power Mode

Using the Low Power Mode will reduce power consumption on your iPhone by disabling or limiting some features like background app refresh, automatic iCloud uploads, auto-lock, some visual effects, email fetch, etc. As a result, some features may take longer to update or complete. Having said that, the Low Power Mode is truly a savior in those awful situations when you’re running on a low battery, and you just can’t charge your iPhone. If you’re looking for ways to extend the battery life on your iPhone 12, you can also enable Low Power Mode as it can give you an additional two to three hours of battery life.

8. Disable 5G

One of the most impressive features of the iPhone 12 lineup is that all the models of iPhone 12 series, including the smallest model in the bunch- the iPhone 12 Mini has support for 5G networks. Though it’s good to have future-proof specifications, 5G networks can have a major impact on the battery life. If you keep 5G ON all the time, it can result in faster battery drain on your iPhone 12. Many users have noticed that the battery drains faster on 5G than LTE networks. But, there’s no need to worry as Apple allows you to enable/disable 5G on your iPhone 12. 

Moreover, if your network carrier doesn’t support 5G, or there’s no 5G network coverage in your area, there’s no point in keeping 5G turned ON all the time. In such cases, it’s better to switch to 4G/LTE networks.To do this, head to Settings > Cellular > Cellular Data options > Voice and Data and select LTE.

9. Use Wi-Fi over mobile data

If improving the battery life on your iPhone 12 is your priority, try using a Wi-Fi network over Mobile Data, whenever possible. Having said that, it doesn’t mean you should always keep the Wi-Fi turned ON. If you’ve turned ON Wi-Fi and there’s no Wi-Fi network available, your iPhone will keep searching for a network, and this will consume battery unnecessarily. Therefore, you must turn OFF Wi-Fi on your iPhone, when there’s no Wi-Fi network available or when you don’t need it. This will help you save battery. 

Also, if you face an excessive battery drain on your iPhone 12/ 12 Mini or if your iPhone 12 Pro/ 12 Pro Max battery drains overnight, you must disable the Wi-Fi by going to Settings > Wi-Fi > Turn OFF the slider for Wi-Fi. It will disconnect the Wi-Fi until you turn it ON by yourself. If you disable Wi-Fi from Control Center, it will disconnect the nearby Wi-Fi until tomorrow, and will then turn it ON automatically. 

It’s good to make a habit of disabling all the features that you don’t need. To know more in detail, move to the next step.

10. Turn OFF the features that you don’t need (Wi-Fi, Mobile Data, Location Services)

Do you keep Mobile Data, Wi-Fi, Bluetooth, or Location Services turned ON all the time on your iPhone? If so, change your habit to fix battery drain problems on your iPhone 12. It will also improve the overall battery life on your iPhone. 

Many users have reported iPhone 12 battery drain overnight problems on iPhone 12, and keeping the unnecessary features ON all the time may be one of the main reasons for such issues. Mobile Data and Location services are known to be amongst the major battery killers on any smartphone, and the iPhone 12 is no different.

Playing games or watching movies at a stretch, especially on mobile data can result in faster battery drain problems on your iPhone 12 or iPhone 12 Pro. Whenever possible, try using a Wi-Fi network over Mobile Data. And, if you’re using Mobile Data, make sure to turn it OFF if you don’t need the internet.

Location services also have a huge impact on the battery life. To turn OFF Location services, go to Settings > Privacy > Location Services, you can either turn the location services OFF or choose to allow an app to access your location while using the app. If you select the latter option, an app can access your location only when you’ve opened or are actively using a particular app. This can be particularly useful for apps like App Store, Google Maps, and others that do not require location services all the time. 

The same rule applies to Bluetooth and Wi-Fi. Just disable them from Settings when they’re not in use. Make a habit of turning OFF all the features that are not in use to fix abnormal battery drain issues on iPhone 12.

11. Use Dark Mode

As all the models of the iPhone 12 Series have got the Super Retina XDR OLED display, using the Dark Mode can help improve the overall battery life on your phone. This mode will darken your device’s display (overall theme) for easy, strain-free viewing in low-light conditions. 

It’s worth knowing that the OLED screen consumes more power to display bright colors as compared to the darker ones. The OLED displays light up every individual pixel to create an image, as compared to the whole display on iPhones with LCD displays. When you switch to Dark Mode, the pixels don’t need to turn on individually and as high as compared to other colors. Besides adding more time to the battery life, Dark Mode also offers a great viewing experience with deeper blacks and brighter whites. Therefore, there’s one more solid reason to switch to the Dark Mode.

Follow either of the steps to enable Dark Mode on iPhone 12:

1. Go to Control Center, press and hold the brightness control, and tap Dark Mode. 
2. Head to Settings > Display & Brightness and Tap Dark.

You can either set Dark Mode on your iPhone automatically from Sunset to Sunrise or set a schedule as per your requirements.

12. Disable dynamic wallpapers and widgets

The way in which you use your iPhone has a major impact on the overall performance of the device. If your iPhone 12 battery drains abnormally faster, you must check if you’re using Dynamic or Live wallpapers. If so, disable these wallpapers and switch to the regular ones. We’re saying this because dynamic wallpapers will move continuously based on the movement of your device, and this consumes more battery. Live wallpapers show animation when you use a 3D Touch on the wallpaper. To fix battery drain problems, disable dynamic or live wallpapers, and choose a still or an image from the Photo Library. For this, go to Settings > Wallpaper > Choose a New Wallpaper. You can either choose an option from Stills or select an image from your Photos.

Talking about widgets, they are undoubtedly one of the most exciting features of iOS 14. Apple has revamped the widgets experience by making them more data-rich. Plus, the ability to add widgets right on your home screen, alongside other apps, is definitely impressive. Now that doesn’t mean you should go overboard with them. You may have added some widgets that you don’t even need, and if the widgets use Location Services, it can lead to more battery consumption, and can even cause faster battery drain issues on your iPhone 12. To be on the safe side, check and remove the unnecessary widgets that you don’t need. This will help save battery on your iPhone 12.
