iPhone 14 Battery Drain Issues

I don’t know if you had time to read the rest of the discussion here or if it was on another forum for Apple where I saw the issue. I had this problem after I downloaded the 16.5 as did a lot of other people on different iPhones. And some people had it after downloading the 16. Apple finally fixed it with a 16.6 update is the latest one it’s not the 16.5.1(c) update . I was very upset with Apple because they never claimed that that caused the phone to get hot and to drain the battery quickly. I was going to go into Best Buy to exchange my phone because I have the warranty on it still. But after I downloaded the 16.6 iOS update, my phone was back to acting normal. It does not get hot and the battery doesn’t drain. It’s back to the way it was before the 16.5 update. So before you do anything I would try updating the to the 16.6 iOS update. Other people have also said online that help them and have fixed their phone also doing that. I am sorry I am dictating this on Siri so I’m sorry if it’s not understandable anyway take care and I hope this works for you bye

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.
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.
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.
4. Avoid Draining the Battery to Zero: Charge it whenever the charge becomes lower than 20%
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.
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.
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.
11. Limit Background App Activity: Close or force quit apps that are running in the background but are not needed. Double-press the home button (or swipe up from the bottom on iPhone X or later) and swipe away the unnecessary apps.
12. 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.
13. 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.
14. 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.
15. 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.
16. 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.
17. 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.
18. 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.
19. Disable Background App Refresh for Cellular Data: If you have limited data plans, consider disabling Background App Refresh for cellular data to reduce data usage and preserve battery life. You can find this option in Settings > General > Background App Refresh.

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

I have exactly the same issue but on all my iOS devices. It seems it's coming from an insane amount of traffic going to and from iCloud. If you reset your mobile data stats and come off wifi you should see what I mean, it is doing about a gb in 10 mins. Not backing up just "messaging services", I have just done some analysis on my wifi network and all the data is coming from iCloud, so when you drop off wifi it's hammering the data connection. Sadly I don't have a fix yet I am still working on it, but wanted you to know your not alone.

Good News! Just upgraded to IOS 16.6 and my phone immediately cooled down. For everyone suffering with IOS 16.5 battery issues. Please do the latest update!

I was having the same problems and upgraded to iOS 16.6 and it is fixed!

Update to 16.6 and that should fix it as it has for everyone else who commented above.

Luckily there’s a fix… upgrade to IOS 16.6 and your battery issues will go away! Not sure what was wrong with IOS 16.5? But it caused the phone to heat-up and use battery power at an alarming rate!

Wont disabling cellular data under iCloud fix this issue, at least when not connected to WiFi?

Turn off 5g completely and it should last!

Is your iPhone hot?

My experience says this is purely caused by some third-party app that you may have installed.

I am not aware of the ambient temperature in which you are using the iPhone. However --> Keeping iPhone, iPad, and iPod touch within acceptable ...

Store the device where the temperature is between -20º and 45º C (-4º to 113º F). Don’t leave the device in your car, because temperatures in parked cars can exceed this range.

Use iOS devices where the ambient temperature is between 0º and 35º C (32º to 95º F). Low- or high-temperature conditions might cause the device to change its behavior to regulate its temperature. Using an iOS device in very cold conditions outside of its operating range might temporarily shorten battery life and could cause the device to turn off. Battery life will return to normal when you bring the device back to higher ambient temperatures. Using an iOS device in very hot conditions can permanently shorten battery life.

Thank u for confirming what I was hoping was real!! I had updated to the 16.5.1(c) & Nothing changed! My iPhone 14 was still getting hot when charging it & the Battery was rapidly draining ! So when I upgraded to the 16.6 I wasn’t holding my breath! But my phone so far has not gotten warm nor is the Battery rapidly draining!! I still have my fingers crossed though!
