iPhone battery draining fast – how to fix the issue?

In this article, I have shown 10 proven fixes, which have been found to work in most cases, when someone finds his iPhone battery draining fast all of a sudden or the iPhone not holding charge for long. If you are also facing the same issue and you see your iPhone battery drains fast then you have come to the right place.

You may often hear from iPhone users – why is my iPhone battery draining so fast all of a sudden? I also found my iPhone 6 battery draining fast even when not in use. It is often reported that iPhone 7, iPhone 6, or iPhone 6s battery drain fast after up-gradation of the devices to iOS 10, 11, or 12.

If you see your iPhone battery dying fast and you can’t even make it through the day without charging the device, it is suggested that first you follow the general performance tips given below as recommended by Apple, which is applicable for all iOS devices including iPad.

1. Avoid extreme ambient temperatures. iPhone, iPad, iPod, and Apple Watch work best at 0° to 35° C (32° to 95° F) ambient temperatures. The recommended storage temperature is –20° to 45° C (–4° to 113° F). Avoid exposing your device to ambient temperatures higher than 35° C (95° F), which can permanently damage battery capacity;

2. Remove your device from its case during charging. If you charge your device when it’s inside its case it may generate excess heat, which can affect battery capacity;

3. If your device is in storage for a long time, the environmental temperature and the percentage of charge on the battery when it’s powered down for storage, may affect the overall health of your battery.

It is, therefore, recommended,

i. Do not charge or discharge your device’s battery fully when it is stored for an extended period. In such cases charge the battery to around 50 percent only. If you store the device when its battery is fully discharged, the battery could fall into a deep discharge state, which renders it incapable of holding a charge. Conversely, if you store it fully charged for an indefinite time, you may see the battery of your iPhone not holding charge as it should leading to shorter battery life;

ii. Power down the device to avoid additional battery use;

iii. Place your device in a cool, moisture-free environment that’s less than 32° C (90° F);

iv. If you plan to store your device for longer than six months, charge it to 50 percent every six months;

iPhone battery draining fast all of a sudden – how to fix it?

If you see your iPhone battery draining fast all of a sudden without any apparent reason and your phone gets hot, try the 10 proven tips given below on how to fix iPhone battery draining fast. If followed correctly, these would make your battery last longer without sacrificing its functionality. These are also definitely going to improve the battery life of your iPhone significantly.

1. Check Battery Usage

If you see your iPhone battery dying fast, the first thing would come to your mind –  why is my iPhone battery draining so fast and what drains my iPhone battery?

If you are using iOS 9 and the later version it has an excellent new feature, called Battery Usage which helps to find the cause of why your iPhone battery draining fast. When you are not sure, why is my iPhone battery draining so fast and what is draining my iPhone battery, then this feature will identify the guilty app responsible for why is your iPhone battery dying fast.

Once you find what drains your iPhone battery, as a first step, update the guilty app for which your iPhone battery draining quickly. If the app still causes problems, you can eventually remove it. You can always re-download these apps at a later date if you find that these apps are not responsible for why your iPhone battery battery drain fast.

Follow the steps below to check battery usage on your iPhone or iPad and clear your doubt – why is your iPhone not holding charge?

i. Go to Settings > tap on Battery;

ii. On the Battery screen, wait for a few seconds for the Battery Usage feature to load;

iii. Tap the “Last 7 Days” option to see the percentage of battery used by each app in the last 7 days;

iv. Tap the ‘time’  sign to see the detailed information of each app;

v. Find out which apps eat your iPhone battery the most;

vi. Now you can decide whether to update or remove the guilty apps. If you find any app that you seldom use is draining your battery abnormally uninstall it;

2. Enable “Low Power Mode”

Enabling Low Power Mode reduces iPhone battery drain and makes your iPhone battery last for several hours longer than in normal mode. When Low Power Mode is on, mail fetch, background app refresh, automatic downloads, and some visual effects are reduced or turned off automatically. This will greatly increase your iPhone battery life. When it is enabled you will see a Yellow battery bar on iPhone. To enable this, go to settings > tap Battery > toggle the switch next to ‘Low Power Mode’ to turn it on.

This feature is only available on iPhones that are running with iOS 9 and later versions, and the iPad doesn’t have this feature.

3. Turn off ‘Raise to Wake’

The ‘Raise to Wake’ option in your iPhone settings is turned on by default with iOS 10. The ‘Raise to Wake’ feature automatically wakes your iPhone or iPad screen as soon as you pick it up from flat on a surface. If you move around a lot with your iPhone in your hand, your iPhone screen wakes up automatically and remains constantly turned on which is one of the causes why your iPhone battery dies quickly. Therefore, at any time if you see your iPhone battery draining fast all of a sudden, turn off the ‘Raise to Wake’ feature to save iPhone battery life.

To do this, go to Settings > tap Display & Brightness > toggle the switch next to ‘Raise to Wake’ to turn it off.

4. Update apps (including iOS updates)

Sometimes outdated apps can be the cause when your iPhone 8, iPhone 7, iPhone 6, or iPhone 6s battery drains fast suddenly. Normally software updates often include bug fixes some of which at times may be the cause of why your iPhone battery dying fast. When Apple releases a new iOS update, developers also prepare and optimize their apps for the latest version. Therefore, ensure that your iPhone or iPad is working with the apps with the latest iOS version. Taking time to update all the available apps may affect your iPhone or iPad battery life considerably.

To update apps, open App Store > Tap ‘Updates’ at the bottom right of the screen > Tap ‘Update All’ in the upper right corner.

5. Turn off “Background App Refresh”

how to save iPhone battery

The ‘Background App Refresh’ feature refreshes the apps on your iPhone in the background which is to say your apps continue to update even when you’re not using them. This is intended to save the loading time of the apps. But allowing all your open apps to continually update and refresh in the background also becomes one of the causes why your iPhone battery drains fast. Therefore, you should turn this feature off to extend the battery life on your iPhone or iPad.

To turn it off go to Settings> General> Background App Refresh> Toggle ‘Background App Refresh’ to the off position.

6. Disable “Location Services”

iPhone Location Service may also be one of the causes of why your iPhone battery dies fast.

iPhone’s location service determines your approximate location using GPS, Bluetooth, WiFi hotspot, and mobile tower location and passes on the information to different apps that help to find restaurants and more for you. But, like any service that sends data over a network, it needs battery power to work. Therefore, if you don’t need to use Location Service and don’t plan to use it right away, turn it off to prevent from iPhone battery draining quickly.

To turn it off go to Settings > tap Privacy > tap Location Services > toggle the switch next to ‘Location Services’ to the off position.

7. Turn on “Airplane Mode”

If you see your iPhone battery draining quickly, one of the major reasons may be poor cellular service. When you are in a place of low signal, your iPhone will increase the power to the antenna to stay connected enough to receive calls and maintain a data connection. This depletes your iPhone battery in no time.

When you see your iPhone battery draining quickly, to prevent it, turn on ‘Airplane mode’ by swiping up from the bottom of the Home screen of your device to access Control Center and tapping on the Airplane mode icon or go to Settings > Airplane Mode > Toggle ‘Airplane Mode’ to ON position. Once you’re back in an area with a strong signal, use the same steps to turn off Airplane mode.

But please bear in mind that when your iPhone’s Airplane mode is turned on, you cannot make or receive any phone calls.

8. Turn off ‘vibration’

Vibration alerts can drain your iPhone battery more than anything else especially when you get a lot of push notifications. If you turn off vibration alerts on your phone, you’ll notice a considerable improvement in battery life. To turn off vibration go to Settings > Sounds > turn off ‘Vibrate on Rings’ and ‘Vibrate on Silent’.

9. Turn off the ‘Auto-brightness’ feature

The Auto-Brightness feature of your iPhone may be also one of the reasons why your iPhone battery drains fast. This feature of your iPhone adjusts the display brightness of the device according to the lighting of your existing surroundings. It always keeps the display brightness at its highest level depleting your battery life. Therefore, if you see your iPhone losing charge fast turn Off the Auto-Brightness feature and adjust the brightness yourself to a lower level according to your requirement.

To turn it off go to Settings > tap on Display & Brightness > Turn off Auto-Brightness and adjust the brightness to a lower level by swiping to the left.

10. Turn off WiFi when not in use

If you do not turn off WiFi when you are not connected to a WiFi network it makes the WiFi of your iPhone or iPad hunt around for WiFi networks it could join. This will consume battery power. Therefore, when you are not using WiFi you should turn it off to stop unnecessary iPhone battery drain.

To do this go to Settings > tap WiFi > toggle WiFi to the off position.

Besides the above fixes, another point also needs mentioning in this connection is that all kinds of viruses consume lots of power and cause the battery of devices to run out faster. Therefore, when you are not sure, why is my iPhone battery draining so fast all of a sudden, a virus or malware infection may also be one of the reasons. However, the likelihood of such happening is extremely low in the case of iOS devices. Here is how to check for viruses on iPhone.

Frequently asked questions

Now that the discussion above has addressed the query often made by iPhone users – why is my iPhone battery draining so fast and how to fix iPhone battery draining fast, let me also address some of the related questions often asked by iOS users:

Why do iPhones die so fast?

Most battery problems on an iPhone are mainly related to software issues and not due to faulty batteries. Only a small percentage comes from faulty batteries. Apple has designed the batteries of its devices to be strong and safe for use. The main cause of concern for the battery issues of iPhones is the downloaded apps. More specifically, the cause of iPhone battery draining fast is how these apps perform and their various settings.

Why is my iPhone battery draining fast?

When you see your iPhone battery drains fast the question may come up in your mind – why my iPhone battery is draining fast without any apparent reason?

There may be two possibilities why your iPhone battery draining quickly. Either the battery is depreciating or something in the system is draining your battery power more than usual. To fix the issue, you need to look into both the hardware and software aspects of your device and follow the fixes suggested in the post.

Some of the major reasons why your iPhone battery draining fast all of a sudden are,

1. Poor battery health;

2. Some apps consume too much battery power;

3. Too high screen brightness;

4. Enabled location services when not in use;

How long do iPhone batteries last?

As per Apple, an iPhone 5, from full charge condition, offers up to eight hours of talk time and Internet use on 3G, 10 hours of Internet use on WiFi, 10 hours of video viewing, or 40 hours of using audio besides 225 hours of standby time. The Battery life of earlier models may, of course, vary.

How do I know if my iPhone battery is bad?

If you see your iPhone not holding charge as long as it used to, then you can check about this in the iOS settings. For this, go to Settings > Battery.

If it’s in bad condition, you’ll see a notification at the top of the screen that says, your battery needs to be serviced.

How to check if my iPhone battery needs replacement?

To check if your iPhone battery needs replacing

1. Go to Settings > Battery;

2. Tap on Battery Health;

3. Here you will see the “maximum capacity” of your battery in percentage which is a measure of your battery capacity relative to when it was new;

4. Below that you can see your battery’s present ‘Peak Performance Capacity’;

At what percentage should I charge my iPhone battery?

The ideal charge level for a stable battery is between 40 and 80 percent. It would be best if you could maintain your battery charge in the upper mid-range of the above. Keeping your battery in the above range will help you to get the most out of your battery. Leaving your phone plugged in when it’s fully charged (like charging overnight) is bad for the battery in the long run.

How to fix iPhone 13 not charging

Try the following steps to fix when your iPhone 13 not charging:

1. Hard Reset your iPhone;

2. Check your iPhone Lightning Cable;

3. Check the iPhone Charger;

4. Check your iPhone’s Charging Port;

Conclusion

Now that you know – why is my iPhone battery draining so fast, try to follow the following tips besides the fixes mentioned in the post:

> Turn off as many background apps as possible;

> Turn off Bluetooth & WiFi if you aren’t using them;

> Turn your screen’s brightness down as low as possible without straining your eyes;

> Don’t use battery-hogging apps like Facebook too much;

> And finally, don’t unnecessarily check your phone frequently;

As far as my experience goes, it can be assured that when you find your iPhone battery draining fast and you follow the tips given above, you will be able to stop your iPhone battery drain in most cases and save your iPhone battery life significantly under normal circumstances.

If you see your iPhone battery dying fast even when not in use and the issue cannot be resolved following the above fixes, the only way to tell if your battery is defective is to take your phone to an Apple Store or an Authorized Apple Service Center and have them test it.

If the iPad or iPhone battery drains fast even after following the tips above your best option is to purchase an external battery pack or a battery case. I have found ‘Anker PowerCore 20100’ to be the best external battery pack so far in the market. It is not too heavy and it can be carried easily into different kinds of pockets in your bag. It can recharge an iPhone up to 7 times from 0 to 100% depending on the model.

Please share in the comment section below if you have any other better solutions when your iPhone battery drains fast or when the iPhone not holding charge for long.

    You make it sound like a user problem when in fact it is entirely a scummy Apple tactic that they always use right before a new phone model is about to come out. Just call out Apple for what it is (a dodgy company)… all works well, new ISO update comes right before a new iPhone release, and battery magically starts draining faster than normal. I seriously can’t stand Apple and I’m thinking of going to Android.

      I tend to agree with you. Not only that, but its always the same 10 things they recommend doing to extend battery life. I’m not talking slow drain under regular use, I’m talking nearly 1% a minute during use. It’s ridiculous.

      The only thing I haven’t done yet is factory reset my phone, which I shouldn’t have to do that to fix a battery drain issue either.

        I agree as well. I bought an iPhone 7 new less than 2 years ago. Was doing wonderful. No new apps. Just the last 14 update I think in October. Ever since, the battery is just draining every day quickly. I do Not do any social media. I do very little on the phone other than a couple calls and a few texts, and a little web browsing. Just doesn’t make sense. I’m sure it has something to do with the last update.

          Totally disagree with the android comments. I have both apple & android phones. Android are not difficult to use/navigate, they are far more user friendly than apple. You have never had battery problems with apple? Bullsh@t…. You either work for apple or are a complete kn@b! How do you explain the thousands of google hits for battery issues with iPhones and iPads? And also it’s every time they do an update before a new release.. it’s clear they are doing it deliberately, they even admitted to slowing previous models before!

      Switching from Apple products is not the answer.
      I guarantee you will have more issues when using an android product, plus you will hate the unintelligent operating system. Androids are not as friendly as apple products.
      I would research other avenues in your settings. something is running in the background that you are unaware of. Or somehow, your battery has been compromised.
      As you add new apps, be sure to never allow notifications or location unless absolutely necessary for the use of each specific app.
      I have owned iPhones since their inception. I have never noticed any major battery drains after iOS updates or when a new iPhone is soon to be released.
      I never buy the newest iPhone just because a new one is released. I still have an iPhone 7 and the 13 should be released later this year.

      After a new iOS update is released, simply take the time to learn what is changed, review your settings again and tweak it to better aid your iPhone and battery usage

    Siri also running in background learning from every single app you downloaded. I’m disabling Siri and it’s ability to learn how I use every single app which is uploaded to iCloud. They make you turn that off one by one in each app instead of a universal way to turn off globally across all apps under Settings/Siri & Search/

    iPhone 6s running 13.3. Phones will go from >80% to less than 5% in seconds, and crash.. If I don’t plug it into a charger, it won’t reboot. Plugging it into a charger it boots up and within seconds goes from about 5%, back to 80%. Sounds like a software issue. I backed up to cloud (10 hours), did a hard, factory reboot, reinstalled all apps, updated all apps. Everything I could find online, and still had the same issue. This all started two weeks ago. I upgraded my iOS a few weeks earlier, and now feel it was a mistake. Last night I put it in airplane mode and took it off the charger. It was fine this morning until about 10 seconds after I took it off airplane mode, then it crashed. I have only installed one new (news) app in the past 2 months, and I removed it on the chance that it might have issues, but it made no difference. Currently, my phone can’t be used more than 5 minutes without crashing, unless tethered to a charger, or in airplane mode. I had power issues (heating up and discharging rapidly) 1 year ago, and had the battery replaced by Apple. No problems since then until now. I am out of the country for another year (in Mexico), and will either dump Apple when I get back, or get a new phone and never upgrade the iOS again. It is hard to go android when all the kids and grandkids have iOS and use FaceTime to communicate with me.

    Same problem with my iphone 6. After I upgraded, it’s worst! Now it doesn’t reboot! I am packing it & keeping it in the fridge for a day as a friend advised to do so to make the battery work again! We all know that batteries wear off, but it cannot wear off suddenly like it’s happening with Apple! Apple needs to answer the customers!

    There is another issue with older iPhones such as the iPhone 5s where the U2 charging chip in your phone can be damaged by using a non-apple charger or charging through your car’s USB port. This happened to me and now my phone, with a brand new battery mind you, goes from 100% to 10% battery capacity in less than six hours. There is nothing that can be done. Getting it fixed would cost too much. I am planning on getting a new phone.

    Also, there should never be a reason to do all of the things listed in this article. It just shows you what a crappy product the iPhone is.

      Hi RCS,
      Putting the phone in Airplane mode does not shut down apps. Any app can run in background, and can attempt to access data for updates. Thus, airplane mode can cause battery drain just by being enabled, and can potentially use more energy than if it could connect to data. Usually it is a rogue app constantly running in the background.
      To fix the issue,
      Go to Settings > Battery and scroll down to ‘Battery usage’ to see the apps that are consuming your battery. If any of the apps have unusually high usage they can be shut down.

      Needier updates needier another fact described here, most important on all devices with display and Li-Ion battery, is to keep low light on Screen because the Screens from all devices consume enormous because of Backlight (under the LCD Screen for you can see what LCD Screen show) and another fact is: when is made the battery I mean the date (day, month, year) when manufacture release the battery and how many months keep in store until come in hands of Customer because if it’s come to Customer after 3, 5, 6 months, the Li-Ion battery it’s already consumed and after 1 month 3 months the battery is depreciated and refer to all kind of batteries less Ni-Cd which is important to be stored with low capacity possible. And do not forget anybody from this forum, all Li-Ion batteries have inside an Safety Electronic device based on little Processor to analyze carefully all the time the stage of Battery in Safety terms because the Li-Ion batteries are very dangerous then, check the date of manufacture to be with maximum one month in storage or, in the seller store more than 2 months and with 50% charge also the Li-Ion battery become soon obsolete.

    I have an iPhone 7 (10 months old) as well as an iPhone 6 ( 4 years old – original battery).
    iPhone 7 battery suddenly discharged quickly about 2 months ago.
    After frustrations with Apple I fully charged iPhone 7 and turned power off for 12 hours. When I turned iPhone on again battery was at approx 50%
    To double check I did the same test with old iPhone – 98%
    Apple say no problem with battery – I agree
    Apple say no problem with iPhone because diagnostics say so.
    Despite reinstallation and resets by Apple my problem persists. Apple say there is no problem
    I am about to go to Consumer Affairs Department armed with video and screen shots to prove my point.
    Just because diagnostics can’t find a problem this doesn’t mean that there is not a problem.
    Any suggestions?

      Hi Duwal,
      Sorry for the delay to reply.
      Low Power Mode is an easy way to extend the battery life of your iPhone when it starts to get low. You can enable it by going to Settings > Battery. Low Power Mode reduces display brightness, optimizes device performance, and minimizes system animations. Apps including Mail will not download content in the background, and features like AirDrop, iCloud sync, and Continuity will be disabled. When your phone charges up again, Low Power Mode automatically switches off.
      Additionally, doing a forced restart can sometimes reset a runaway process.

    I recently did an upgrade to IOS 14.2 which I had not uodated for a very long time. I have a 6s plus. At 3:00 AM to 3:15 AM EVERY morning, while I am sleeping my battery goes from 60%-100% to 1%.
    Even when turn my phone off at night and this still happens EVERY night unless I keep my phone plugged into the charger all night. My battery reads I have 82% life left. This only started after this latest update. I am on low power mode, battery saver mode and followed all the suggested fixes and it still drains at around 3:00 AM
    1- is there a way to delete the update? 2- Is there any fix? 3- what you do if this was happening to you?

      Hi Geegee,
      Sorry for the delay in replying.
      While iOS 14 is far from bug-free and it would be wise to wait a few days for developers to catch-up. The issue was for developer beta version and it has many bugs. Due to UI Changes the older models get battery drain issue which is very common in beta versions. Please get back to iOS 13 to avoid the battery drain issue.

    My phone Xr quickly loses power from 50% to shut down.
    – I charged it to 90 % overnight and it holds the charge till morning. I started using the phone till battery drops to ~50% and then suddenly the phone switched off.
    Mostly this happens when I’m on the video call or zoom or FB. Software is 14.1 and battery health shows 90%. Is there any calibration issue here, I use the phone while charging most of the time. Appreciate your suggestion. Thanks.

    SOLVED (at least for me)!
    Over several weeks after upgrading from 13.7 to 14.4.x I tried turning off MANY Settings and offloading all 3rd-party apps etc — to no avail. Still sluggish, overheating, and fast battery drain anytime screen was on.

    An apple-support tech mgr suggested doing a full Settings&Content Reset (after a backup) to confirm if a hardware problem. Phone worked fine as as empty new phone… so was definitely confused software.
    So I re-did the full reset and restored from iCloud backup and it SOLVED this problem on my iPhoneSE(1st gen).

    So do THIS:
    – do a full icloud-backup (pay 99 cents for 1 month of increased icloud storage)
    – Settings/General/RESET ALL CONTENT AND SETTINGS
    – Follow new-phone setup steps and login into your apple ID and restore from the iCloud backup.

    After doing those my SE was back to normal!! 🙂

      Hi Ethicks,
      Thanks for your comments. There are several reasons which can drain your battery fast. You can try the following fixes to solve the issue:
      1. Update iOS and wait for a day to sync all settings;
      2. Find the apps that are consuming your battery and take action accordingly. For this go to Settings>Battery and see which app is consuming the highest percentage of your battery;
      3. You may have apps running in the background that are draining your battery. Try background app refresh to see if that helps. For this go to Setting> General> Background App Refresh;
      4. If you have WiFi and/or Bluetooth turned on but not connected to anything, that can drain your battery faster than normal;
      5. Another reason may be that the battery is not yet calibrated because you just replaced it. You need to fully charge and fully discharge the battery 3 times so that the battery is fully calibrated and shows a more accurate battery percentage charge. Go through 3 full charge cycles, from 100% to 1% and the battery should be normal;
      6. Even after trying the above fixes if still the battery drains, then it’s possible you got a LOW QUALITY battery that wasn’t built with high quality standards;

    I’m moving to a Jitterbug!! (it’s a smart phone for seniors). I just can’t handle all this technology in the palm of my hand. If you have any respectful advice, I’d take it!

    I have an iphone 6s. on the locked screen, it says 100% charged but the battery percentage says otherwise. Please what could be causing this?

    The sudden battery drain is a programmed feature in certain Apple updates that was designed to compel users to buy the latest iPhone. If you have sudden battery drain I would recommend updating all your data to the cloud and then wiping your phone and then re-download in all of your data/contacts. This put my phone back to normal function ability. Thanks
