Why Is My iPhone Battery Draining So Fast?

iPhones are considered to be the most reliable smartphones in the market. Each iPhone device performs good performance for 2-3 years after its launch. Apple promises iOS version updates which makes these smartphones more reliable. Even after some years of launch, Apple iPhones perform very well, but the battery starts draining fast. Many people ask, ‘Why is My iPhone Battery Draining so fast all of a sudden?’. There can be many reasons for this problem. This article will discuss all these reasons and how we can stop our iPhone battery from draining very fast.

Common Causes of Fast Battery Drainage and their Solution?

The most common problems and reasons due to which iPhone battery dies fast are discussed below:

Use of Phone Cover While Charging:

The phone battery has an internal resistance that generates heat when charging the phone. In ideal conditions, it is okay to use phone covers while charging. According to Apple, you can use your iPhone where the temperature is between 0°C to 35°C. If you live in an area where the temperature remains between 0°C-35°C, you can use the iPhone covers. While living in a city where the temperature remains moderate, you should consider not using a phone cover if you still face battery issues.

And if you live in such an area where it is hot during the whole year, you should avoid using phone covers on your iPhone.

Heat and high temperatures can cause a decrease in battery health.

Storing your iPhone without taking care of Battery Health:

When we store our phone for a couple of months or a year, we don’t think about what will happen to the phone’s battery.

We suggest that Whenever you want to store your device for a long period, don’t charge or discharge it completely. You should charge 50% of the battery and then store it. If you store the device at 0% battery, then the battery can go into a deep discharge state. In contrast, the battery capacity can decrease when you store it by charging it fully.

If you are storing the phone for more than six months, It would be best to charge it 50% every six months. It will help maintain good battery health if you take all these measures.

Battery Health:

Battery health refers to the maximum storage capacity of the battery. If your iPhone battery dies very fast, you should check its battery health. For this purpose:

  • Go To Settings
  • Then Go for Battery
  • Tap on Battery Health. And the battery health of your iPhone will be displayed on the screen.

If the battery health of your iPhone is less than 80%, then you should go for replacing the battery. Because poor battery health can also be a reason why your iPhone battery is draining very fast. iPhones are recommended to be used at temperatures between 0°C and 35°C. Using iPhone at a high temperature can also affect battery health.

  • Contact these Service providers to get your iPhone battery replaced. You may also get other repairs if your iPhone has any other problems.

Background App Refresh:

Background App refresh feature is another cause of the iPhone’s battery draining fast. Apps using background Refresh pre-fetch data, get updates from the server and do other things. So that we’ll not have to wait on the app launch, keeping the Background App Refresh On is fine. But if you’re facing battery timing problem, you can turn it off because this feature also consumes a lot of battery power. To turn background app refresh off:

  1. Go to Settings
  2. Go to General
  3. Then tap on Background App Refresh Option. A screen will appear to control the Background App Refresh feature for each app and for the whole phone.

You can also consider finding good alternatives for apps using a lot of battery power.

Heavy Usage and Gaming: Reason why your iPhone battery drains fast all of a sudden

Heavy usage such as video editing and gaming on an iPhone can cause your iPhone battery to drain very fast when you run heavy apps on your iPhone or do heavy tasks. You can play all the games on the latest iPhones and do any tasks, but you should remember that an iPhone is not a gaming phone. iPhones are not designed especially for gamers. Gamings phones are specially designed for gamers. Gaming phones provide long battery timing even when you play heavy games on them.

Outdated Version of iOS and Apps:

When apps become outdated, they start lagging and consume more battery power. Also, when the iOS version becomes outdated, the iPhone starts lagging, and sometimes features stop working. And the Phone starts heating up again and again, which is also harmful to the battery health. So we should keep updating apps and the iOS to prevent the iPhone battery from draining very fast.

To update the iOS version:

  1. Go to Settings
  2. Go to General.
  3. Tap on Software Update. A screen will open where you can check for updates and update your iOS version.

To update apps:

  1. Go to App Store
  2. Tap On your Apple ID profile Picture (In the top-right corner)
  3. Scroll down and then tap on Update All.

Turning the Low power mode On:

In low power mode, the iPhone consumes less power, and in this way, you can improve the battery timing of your iPhone. Low power mode affects the following:

  • Email Push & Email fetch (Both are disabled)
  • Background App Refresh
  • Visual Effects
  • iCloud Photos
  • Auto-Lock feature(automatically sets to 30 Seconds).

The battery icon in the status bar becomes yellow when we turn on the low power mode. You can turn on the low power mode by:

Go to Settings > Battery > Turn On the Low Power Mode

Raise to Wake Feature:

Raise to Wake feature is another feature that utilizes a lot of power. By this feature, the display of the iPhone turns On when we pick up the phone. This feature is not very useful in daily life. But this feature consumes a lot of battery. You can turn this feature off by:

  1. Go to Settings
  2. Go to Display & Brightness
  3. Turn the Raise To Wake feature Off.

This feature is another reason why your iPhone battery drains so fast.

Use of Airplane Mode:

Airplane Mode turns off the sim, WiFi, and Bluetooth. You can use this mode when you’re not using the phone or when you’re going to sleep. Airplane mode can save a lot of battery. You can turn Airplane mode On from the Control Centre and the phone settings.

During an Airplane Flight, the use of Airplane Mode is highly recommended. If you don’t use Airplane mode, your iPhone will keep attempting to catch signals from all the nearby cellular towers on the ground that the airplane passes over. Switching cellular towers constantly causes fast battery drainage of your iPhone.

Vibrations And Haptics:

Vibrations and Haptics also consume a lot of battery power. If you’re facing battery timing problems, you should consider turning the vibrations and haptics off.

  1. Go to Settings
  2. Go to Sounds & Haptics
  3. Turn off the Vibrate On Ring and Vibrate on Silent
  4. Also, Turn off the System Haptics.

Turning the vibration and Haptics off will help you improve the battery timing of your iPhone and to prevent iPhone battery from draining very fast

Screen Brightness:

The most power-hungry component of your iPhone is its display. It will help if you keep the display brightness low. This saves a lot of battery power. You can adjust the brightness of your phone from the Control Centre. And also from Settings > Display & Brightness.

Auto-Brightness Feature:

Auto-Brightness feature adjusts the brightness of your iPhone according to the light conditions. This feature uses the ambient light sensor. You should also keep the Auto-Brightness feature On. This feature will help you save a lot of battery power wasted due to the unnecessary high brightness of the screen. You can turn this feature On easily.

  1. Just Go to Settings
  2. Then Tap On Accessibility
  3. Choose Display & Text Size.
  4. Turn On the Auto-Brightness feature.

Dark Mode:

If your iPhone has an OLED display, turning the dark mode on will help you save battery power.

iPhones With OLED Displays:

The iPhones which have OLED displays are:

  • iPhone X
  • iPhone XS
  • iPhone XS Max
  • iPhone 11 Pro
  • iPhone 11 Pro Max
  • iPhone 12 Mini
  • iPhone 12
  • iPhone 12 Pro
  • iPhone 12 Pro Max
  • iPhone 13 Mini
  • iPhone 13 Pro
  • iPhone 13 Pro Max

Working of Dark Mode:

In dark mode, your screen becomes dark, and the text usually appears white or in a lighter color. If you’re using an OLED display iPhone, the screen cells will be turned off at the areas where the screen is black(Dark). This saves your iPhone battery from draining very fast, but you’ll need an OLED display phone. If you have an LCD display iPhone, you can use the dark mode, but this will not help you save battery power.

In LCD panels, the screen cells are not turned off at the areas where the screen is black.

You can turn on the Dark mode on your iPhone easily.

  1. Go to Settings
  2. Tap on Display & Brightness.
  3. Turn On the dark mode.

Use of Small capacity battery by Apple:

The use of batteries of small charge storage capacities in Apple iPhones can be a cause of your iPhone battery draining very fast. Before you think that there’s a problem with your iPhone, you should compare the battery timing with the original battery timing. Suppose the battery timing provided by your iPhone has a large difference compared to the original battery timing. In that case, you should think about using all the tips and tricks mentioned in this article.

Battery timings may vary a bit due to different factors

Unnecessary Notifications:

Notifications also consume a lot of battery. When a notification comes, not only the screen turns on. But also, the phone vibrates(in the case of Silent mode) or makes a notification sound(in normal mode). A lot of notifications come throughout the whole day. And this is how notifications are another major cause of the fast drainage of your iPhone’s battery. Unnecessary notifications use battery power and also disturb you. It would be best to turn off the notifications for unnecessary apps you don’t use. To adjust the notification settings, Go to Settings > Notifications.

Adjusting the notifications settings

You may also consider using the focus mode while you’re working or sleeping so that no notifications or calls can disturb you at that time. You can adjust when the focus mode turns On. And you can also turn on the focus from Settings > Focus.

Using Wi-Fi instead of Mobile Data:

Wi-Fi uses less battery power as compared to mobile data. Cellular towers are usually located at large distances compared to the WiFi router. Switching cellular network towers also drains a lot of battery power. Sometimes Wi-Fi is available, but still, we use mobile data. If Wi-Fi is available, you should use Wi-Fi instead of mobile data. This will help you save a lot of battery power.

Clearing Recent Apps:

Many battery-saving apps suggest clearing recent apps. You can do it on iPhone 8 Plus and Earlier devices by pressing the home button twice. And to clear recent apps on iPhone X and later devices, you can swipe up from the bottom and pause in the middle of the screen. If you don’t clear a recent app and open it again, the iPhone will consume less power. But When you clear a recent app and open it again. The phone will have to make more effort, and ultimately, it utilizes more power. So We recommend you not to clear recent apps that you will use again. Clearing recent apps and opening them again and again can your iPhone battery drain very fast.

Disable Automatic Downloads and Updates:

Sometimes your iPhone’s battery drains very fast, even when not in use. In iPhone, if Automatic updates are turned On, the phone starts updating apps whenever updates are available. It also downloads apps purchased(including free) on other devices using the same Apple ID. This consumes battery even when you’re not using your phone. It would be best if you disable the Automatic Downloads and updates. For this purpose:

  1. Go to Settings > App Store
  2. Turn off the Automatic Download of Apps and App Updates.

Sharing iPhone Analytics to Apple and App Developers:

As per default settings, your iPhone shares iPhone Analytics with Apple. These iPhone Analytics include:

  • Details about hardware and iOS.
  • Information about how you use your iPhone and apps.
  • iPhone analytics don’t include any personal data.

iPhone also shares App Analytics with third-party app developers to help them improve their apps. This information helps them improve their apps to work perfectly with Apple devices. App Analytics also doesn’t contain any information that identifies a person. App analytics sent to an App developer include specific information about that particular app.

iPhone and App analytics help both Apple and App developer improve their services, but sharing analytics consumes a lot of battery. iPhone keeps sharing these analytics even when it is not in use. If you’re facing battery timing issues, you should turn these features off. For this purpose:

Go to Settings > Privacy > Analytics & Improvements and turn off the Share iPhone Analytics feature.

turning off the iPhone Analytics Settings

Sharing of iPhone Analytics and App Analytics to Apple and App Store developers can also cause fast draining of your iPhone battery.

Location Services:

Location services also consume a lot of battery power. When you aren’t sending your location somewhere or using Apple maps or any other Map routing app, you can turn the location services off. For this purpose:

Go to Privacy > Location > Location Services and turn off location services. This will turn off the location services for all apps. Location services settings are temporarily restored if you use the Find My iPhone feature. So you can disable it without any worries.

turning off the location services on iPhone

But if you want to use location services for some specific apps. You can also control the location services permissions for each app. If you don’t disable the Location Services of all apps, you should at least take the following measures:

Go To Privacy > Location > Location Services > System Services and then disable the:

  • Location-Based Ads
  • Location-Based Suggestions
  • Motion Calibration & Distance(unless you will not use iPhone as a pedometer)
  • And in Product Improvement Section, disable iPhone Analytics, Routing & Traffic

And Improve Maps option because these product improvement features send unnecessary data to Apple to improve Apple Maps and other Apple location-based products.

Chrome Browser:

I am not against Google Chrome. I love it. But due to some unknown reasons, Google does not optimize Chrome browser to work efficiently on Apple devices. The default search engine of Chrome browser is Google. Google shows us the location-based search results. You should turn the location services off when you use Chrome. It will help if you keep clearing the browsing data from the Chrome browser. Because sometimes, redundant cookies also put additional pressure on your device, resulting in more power usage.

Follow these steps to clear the browsing data:

  1. Open Chrome Browser.
  2. Tap on the three dots in the bottom-right corner.
  3. Go to Settings.
  4. Then Go to Privacy > Clear Browsing Data and then tap on Clear Browsing Data.

If clearing data does not solve your problem, you should also check if there’s an update. It would be best if you always keep your chrome browser up-to-date.

If Chrome browser still uses more power and lags. You may consider switching towards Safari Browser. Safari is the default browser that comes pre-installed on all iPhones, so you don’t have to download it. Safari Browser is well optimized for all Apple devices, and it performs very efficiently.

Erase network settings:

It has been seen that erasing network settings on iPhones improve battery timing. If you have a battery timing issue, you should try it once. Erasing Network Settings does not create any problem for you. You’ll just have to retype the WiFi Passwords.

To Reset All the Network Settings:

  1. Go to Settings
  2. Tap on General
  3. Go to Transfer or Reset iPhone option
  4. Tap on Reset
  5. Choose Reset Network Settings

Placing the iPhone facedown:

Placing the iPhone facedown is another trick to save battery power. When we put the iPhone facedown, the sensors of the device sense that the device is placed facedown, then when notifications are received, the screen does not turn on. This also saves battery power. This trick will help you a lot in saving battery power.


Widgets are the mini-apps running on your iPhone. They keep fetching data even when you aren’t checking widgets. This is the reason widgets consume a lot of battery power. You can add and remove the widgets easily. To remove widgets:

  1. Go to the today view(By swiping right from the left side of the screen)
  2. Tap on Edit.
  3. Then scroll down to tap on customize option.
  4. When you tap on customize. A pop-up will appear where you can add and remove widgets.

Editing widgets on today view of iPhone

It will be best if you remove all the widgets. In some cases, widgets utilize more power than apps because apps don’t usually use power when they are not used. But widgets keep updating the data even when iPhone is not in use. This is another reason why your iPhone battery drains even when not in use.

Auto-Lock Feature:

Sometimes we leave our phone unlocked with its screen On by mistake. Someone can read our private messages and other confidential information stored in our phone such as bank account details etc. And also, the screen will remain on without any reason resulting in wastage of battery power.

Auto-Lock Feature is a beneficial feature in iPhone. This feature locks the screen and turns it off after non-usage of the phone for a specific time. Auto-Lock feature should always be turned on. To adjust Auto-Lock feature settings:

Go to Settings > Display & Brightness > Auto-Lock.

setting auto-lock to 30 seconds
Setting auto-lock to 30 seconds

It will be best to choose the 30 seconds option so that your iPhone’s screen will turn off after an inactivity of 30 seconds.

Visual Effects:

Some visual effects in iPhone are displayed on the screen while switching apps and going back to the home screen. As we all know, a lot of power is utilized to render visual effects. These visual effects have no direct impact on our usage of Phone. Visual effects are included to show smoothness while switching apps. Turning off these visual effects can improve battery timing and make the apps switch fast.

To turn off visual effects:

Go to Settings > Accessibility > Motion and turn On the Reduce Motion option.

Visual Effects can be a reason why your iPhone battery is draining very fast.

Email Push & Email Fetch Settings:

What is Push?

When Push Emails is turned on, the messages and emails are automatically retrieved when they arrive in the inbox. iPhone pushes emails automatically from the server to the iPhone in the background and uses a lot of battery power and this can be a reason why your iPhone battery is draining fast.

Fetch Emails:

Some apps and accounts don’t support push(Such as Gmail). For such apps and accounts, Fetch works. In fetch Emails, the iPhone checks for emails and messages after certain intervals. Fetch is supported by all types of accounts.

Which one is better?

If you receive many emails per day, you should turn off Push. Because when you receive many emails, the phone notifies you each time, which uses a lot of battery power. Fetch is better because you can adjust the interval after which the iPhone will check the server for emails. For good battery life, your device should fetch less frequently. For good battery life, follow these steps:

  1. Go to Settings > Mail > Accounts Fetch New Data.
  2. Turn the Push Off.
  3. Change the Retrieval methods of all accounts and services you use to Fetch.
  4. And Select the Hourly option so that the iPhone will check for emails and data after each hour only.

Screen Time:

Although Screen Time helps us remind us how much time we spend on our iPhone, this feature also uses a lot of battery power. It keeps running in the background and notices our screen time. This feature is beneficial for us, but it uses a lot of battery power. If you have battery timing problems, you should disable Screen Time. To Disable Screen Time:

  1. Go to Settings > Screen Time
  2. Scroll down and tap on Turn Off Screen Time.
