iPhone 14 pro battery health reduced to 92% in less than a year

I have an iPhone 14 Pro Max 256GB and the battery health on the

30th Sept 2023 was 96%.

I've been watching it drop like a stone.

19th October 2023 94%

18th November 2023 92%

I have optimized battery charging set on, and I charge from 20% to 90%

My phone does not get hot or cold so I'm wondering why I am losing 2% per month.

In contrast, my iPhone 11 Pro Max 256GB is now only at 90% battery health.

What is going on, are these batteries defective, and is the a replacement scheme by Apple, please?

Many thanks

I have 14 Pro Max 256GB bough on January 2023 and the battery health was 100% till October starting and after that from 17.02 update it start decreasing in Nov it is 95% and in December is 92%.

Thank You

My iphone 14 pro max is at 86% after 13 months, am very disappointed, my previous 11 pro max was at 85% after 36 months. I usually charge daily when its around 20% upto 100% overnight, any advice?

Hey, I've got the same problem can anyone advise me? My phone isn’t even a year old. Dropping battery health by the days I contacted Apple and they have ran diagnostics and say nothing is wrong but at this rate the phone will be useless by summer time.

Same to me. Before updating IOS 17 it was 100% now within 1 month it dropped to 94%

Dear apple we need your assistance on this issue.

I’m not sure how to edit my post so I will add this.

September 96%

October 94%

November 92%

Just checked over the holidays

December 90%

Im watching the batter health of my iPhone 14 Pro Max drop like a stone.

As I said before my 11 Pro Max is currently at 90%!!

What is happening here and will Apple do a battery swap for free or a discounted price does anyone know?

(I doubt it unless there was a recall)

Thanks all

Well to add to my comment my phone is now down to 88% and I’m genuinely not happy about that. 2% down each month what is going on and will Apple replace it?

thanks

I’ve bought iphone 14pro max in September 2023. Now in December 2023 my phone battery heath drain to 98%. Keep charging in order as per advised but still this happened.

To prolong the life of your iPhone battery, you can follow these tips and best practices:

To prolong the life of your iPhone battery, you can follow these tips and best practices:

1. Optimize Battery Charging: Enable the "Optimized Battery Charging" feature on your iPhone. It helps reduce the wear on the battery by slowing down the battery aging process. You can find this option in Settings > Battery > Battery Health. About Optimized Battery Charging on your iPhone - Apple Support (IN)
2. Avoid Extreme Temperatures: Extreme temperatures, both hot and cold, can negatively impact your battery life. Avoid exposing your iPhone to excessive heat or cold, such as leaving it in direct sunlight or in a freezing car.If your iPhone or iPad gets too hot or too cold – Apple Support (UK)
3. Use Original Chargers and Cables: Always use Apple's original chargers and cables or certified third-party accessories. Low-quality chargers or cables can damage the battery and reduce its lifespan. Identify counterfeit or uncertified Lightning connector accessories - Apple Support (IN)
4. Avoid Draining the Battery to Zero: Charge it whenever the charge becomes lower than 20%. The rest is up to you when to charge. how long to charge, how often to charge, which adapter to use starting from 5W to 140W USB-C Power Adapter etc.
5. Optimize Display Settings: Adjust your display settings to optimize battery life. Lower the screen brightness, enable auto-brightness, and use shorter screen timeout durations. Adjust the display and text size on iPhone - Apple Support (IN)
6. Minimize Background App Refresh: Limit the number of apps allowed to refresh in the background. Go to Settings > General > Background App Refresh and disable it for apps that don't require real-time updates. Switch apps on your iPhone, iPad, or iPod touch - Apple Support (IN)
7. Disable Push Email: Push email notifications can drain your battery quickly. Instead, set your email accounts to fetch data manually or at longer intervals. You can change this setting in Settings > Mail > Accounts > Fetch New Data.
8. Disable Unnecessary Notifications: Reduce the number of unnecessary notifications you receive. Go to Settings > Notifications and customize which apps can send you notifications.
9. Limit Location Services: Some apps use GPS and location services in the background, which can drain your battery. Go to Settings > Privacy > Location Services and disable location access for apps that don't require it.
10. Update iOS: Keep your iPhone's operating system up to date. Apple regularly releases updates that can include optimizations and improvements for battery life.
    1. Update Over-the-Air (OTA) —> Update your iPhone or iPad - Apple Support (IN)
    2. Update using iTunes/Finder —> Update your iPhone, iPad, or iPod touch - Apple Support (IN)
11. Enable Low Power Mode: When your battery is running low, enable Low Power Mode in Settings > Battery. It reduces power consumption by disabling non-essential features.
12. Avoid Battery Drain during Storage: If you need to store your iPhone for an extended period, make sure to charge it to around 50% first. This helps prevent the battery from draining completely, which can be harmful.
13. Disable Dynamic Backgrounds and Motion Effects: Dynamic backgrounds and motion effects use additional processing power and can impact battery life. Use a static wallpaper and disable parallax motion effects in Settings > Accessibility > Motion > Reduce Motion.
14. Limit Widgets: Widgets on the Today View can consume battery life. Remove or limit the number of widgets displayed by swiping right on the home screen, scrolling to the bottom, and tapping Edit.
15. Adjust Auto-Lock Time: Shorten the auto-lock time on your iPhone. Go to Settings > Display & Brightness > Auto-Lock, and select a shorter time interval to turn off the screen more quickly when not in use.
16. Use Wi-Fi Instead of Cellular Data: When possible, connect to Wi-Fi networks instead of relying on cellular data. Using Wi-Fi consumes less power than using cellular data.
17. Enable Airplane Mode in Low or No Coverage Areas: When you're in an area with low or no cellular coverage, enabling Airplane Mode can prevent your iPhone from constantly searching for a signal and draining the battery.

By following these tips, you can help prolong the battery life of your iPhone and maintain its overall performance over time.

I currently have iPhone 14 Pro Max purchased new and received in October 2022. After 14 months the battery health maximum capacity is 86%. The 86% is a shock and worrisome number to me. I believe the battery is an issue and a major problem.

Did you notice the battery drop right after an update? If yes, then you are not the only one. I too have faced the sudden battery drop of over 5-6% in almost 3 weeks on my 13 mini. Its a common thing for Apple to knowingly either degrade the battery health or mess up the performance. Also the battery drops more if you have updated the iPhone directly. Connect the device via a Mac or Windows (through iTunes) and then try updating. This will have a lesser impact on the battery health. This is because when you update via iPhone, only the basic update gets installed and the remaining keeps on installing over the coming days. Whereas when you update via Mac/Windows the entire update file gets installed.

14pro max 8 months ago 95% it’s quite better???

Hi there, the metric used to determine the degradation of the battery is not at all accurate and it is there to gauge the life cycles given to a battery. If your phone is charged then discharged to 0 that is a cycle down. If you charged your phone to 100 used it to 50 then you charged it back up to 100 and used it to 50 again that is also a cycle. Percentage is based on the cycles not actual real time degradation of the battery. Hope this helps

Hi Sanket,

Well in this case I assume your phone is still under warranty and apple has one clause were they will replace the device or the battery if it went to 80% in 2 years. I am also using iPhone 14pro max and mine is now 1% after 10 months. So I would suggest you to visit apple service center and just have a cross check or call customer support first.

I bought an iPhone 12 Pro in Feb 2021 and today the battery health is 85% (in 30 Months!).

The measure of battery health deterioration/drainage is subjective and can vary depending on individual usage patterns. There is no universal standard to determine whether the battery health deterioration/drainage is normal or abnormal because it heavily relies on how the battery is used and maintained.
