iPhone 14 Pro Battery Draining Fast

Well, I can think of a dozen reasons, but without troubleshooting I can’t do more to pin it down. I had rather poor battery performance with my XR, but my 14’s battery performance is outstanding, using less than 25% of the battery energy in an average day.

Things to check:

• Top of the list is VPN. If you use it and just migrated it over from your old phone I would guess that’s about a 90% probability of being the problem. Delete the profile and app. Then reinstall them. Better yet, don’t reinstall them, because VPN does nothing useful except expose you to identity theft by the VPN provider.
• Facebook is the world’s largest energy hog.
• Misconfigured account on your carrier’s side - call them to have your account reconfigured.

Lots of other solutions have been posted in this thread, so it would be helpful to read the other posts.

Given different model phones have different radios, different processors and different displays it's not a straight comparison.

For example your iPhone 14 may be operating on a radio band an earlier iPhone wasn't even capable of using, and 5G bands for example do take more radio power than LTE ones.

Then there's the fact that many third party apps are not yet completely compatible with iOS 16.

Hi, FIXED FOR ME

Read the first 4 pages here, and everyone have the same problem I have…

My 11 pro was way better, could use it all day and it would be at 10-15% when I would go to bed. For 2 years!

Iphone 14 pro, had to charge it at noon… because it was down to 44%😂

FIX

Hard reset the phone and update it!

Did it yesterday and it has been amazing today!!

Ha

BTW folks, my battery life since I posted this is fantastic? Took a week to normalize after setup and background downloads, as I was was that this was happening. Love the phone. Do your due diligence and change settings to maximize battery life and things should be fine.

Since 16.3 is released I’ve changed 3 14 pro and 1 14 pro max phones (not sure about the color and the size:)) and the same story on all iphones: battery drain increased, battery capacity drops down after reboot. The origin of the phones were Canada, Japan, South Korea, Hong Kong and some European country. They all ran normal with 16.1 and 16.2. I don’t think this is a hardware iterations. How is it possible? I can’t imagine. I think this is about poor executed 16.3.

Many people are saying that is the 16.3 version but I got my iPhone December and it was on 16.2. I’ve had the same issue since I have the phone. It’s iOS 16 in general. So yeah basically wait for the new update or downgrade if you can.

I mean software produced by teams who do not have the OS developers on speedcall, and who do not have available intimate knowledge of the nuances of the OS and any changes.

Apple do, as you say, check the software they sell against some criteria. Foremost is that they are not malicious or destructive to user's best interests. The intricate interconnections between applications calling for OS services can only appear when a given combination of software is in place and executing.

How many non-apple authored applications do you have on your phone? How many are active in the background with or without your knowledge?

Android has exactly the same problems, so do all software systems, from the mighty machines that run petaflops a second down to my trusty old Windoze XP.

I invite you to locate the problem by removing software products until the issue goes away.

None of the above being intended to say that there is no issue with the OS, merely that, by definition, every app on your phone is running in fewer places than the OS, so encounters fewer confrontations with system services, and fewer reports of bad behaviour.

Note all of Apple’s battery specs are listed as “up to.”

Their figures have in the past been calculated using media already on the phone, not streaming over Wi-Fi and especially not cellular.

Remember the two biggest power users are the display and the cellular radio, especially if you have two bars or less of signal and even more so if you are connected to a 5G network.

'Find My' is trying to stay in contact with the device location, and with no/not enough cellular signal it's permanently shouting in the wilderness 'Here I am' at full signal strength.

Note it's not just "Find My."

When your phone is in a poor cellular reception area it has to periodically check in with the cellular tower so that the tower knows it's there to send on SMS messages and phone calls.

Then the power usage is even higher if you are in a poor coverage area for 5G, as 5G consumes more power to begin with.

Again, there is zero reason you shouldn't have your phone connected to a charger when you're not actively using it.

About Optimized Battery Charging on your iPhone - Apple Support

As I have said before on this thread, it is a very common reaction to blame the iPhone 14 range and/or iOS16 for poor battery performance and, whilst I sympathise with those who are experiencing this situation, I still believe that such blame is misplaced. 

I have a 14 Pro Max which I have been using from new since last November and I use it for just about everything in my life. A typical day will find me listening to music for several hours, using a public transport app giving live departure times, shopping with Wallet and ApplePay, navigating with Maps, reading with Kindle, taking loads of photos and the occasional video, shopping online and spending at least five hours streaming/downloading/watching movies.

I can count the days on the fingers of one hand when I have had less than 50% capacity left in my battery at the close of the day (and never less than 30%). I put my phone on charge around 2100-2200 each evening and unplug it when I wake naturally soon after midnight if it is fully recharged. Battery health is still 100%. I once used the phone for 48hours without recharge just to prove to myself that it could be done. I have always updated the iOS on the first available day. 

To me, this suggests that a) there is nothing wrong with the iPhone 14 per se [mine is the same as everyone else's]; b) that there is nothing wrong with iOS16 per se [again, I am using the same iOS as everyone else]; c) that the disappointing battery capacity performance many people have reported, must therefore be due to the factors in which my device differs from theirs, namely the third-party apps that are installed, or the settings that have been activated since our devices were first personalised from new.

These conclusions seem to follow logically from the facts; if the phone or the OS were at fault, it would be experienced by every single user. 

I really hope that a substantive solution or solutions will be found soon for those who are suffering this syndrome. I wish everyone was experiencing the performance that I have always enjoyed from my 14PM. 

And something I’ve noticed, popping the iPhone on low power mode slows the battery usage by about 10%. As instead of using 60% over 7 hours, it used 52%. Just saying 🥳

Why would you only charge it to 96%?

What is shown as responsible in Settings -> Battery?

How strong is your cellular signal?

Now my phone is fine after the 16.2 update now it last longer and holds for almost a full day and I feel like Apple could do better

Do you have a VPN installed on your phone? If you do, delete it.

What does Settings -> Battery show has been responsible for most of the power usage?
