iPhone 14 Pro Battery Draining Fast

You have 14 days to return it if you bought it from an Apple store.

But your phone has a problem that is fixable, so the best approach is to find why the battery life is poor and fix it. My iPhone 14 and those of many associates is better than any phone I have ever owned. I charged my phone overnight last night (you should also). Now, at 8:30 PM my battery charge is still at 75%. Every other phone I have ever owned would be down to 20% by now, and on some days I would have had to charge it during the day. And there have been many similar reports.

Battery drain has only one cause: apps that use energy. There is nothing else that drains the battery, so to fix it you need to identify the app(s) that uses the most energy. Start in Settings/Battery.

Sorry, but that is simply not true.

First, it IS possible to get a bad battery or circuit board increasing power consumption and second most of the time it‘s not third party apps draining the battery, but Apples own iOS systems daemons and sadly Apple made the decision to hide them in the battery graph, instead of macOS were you can see battery consumption for every process in the Activity monitor.

So battery graph will tell you nothing, apart from that battery is draining.

While it is true a hardware issue or bad battery can be the cause of power loss, it's not very common.

By far the most common is an app that is using far more battery power than it should, either because it is improperly querying other parts of the operating system or due to just poor programming practice.

The battery graph will tell you the battery is draining; the list of apps and the battery power they have used will tell you which apps are using power and how much.

Where did I say it was 3rd party apps? And daemons, by their very nature, are invoked by apps, so ultimately it is the apps that are driving data use.

I did leave out one non-app factor: cellular network use of energy to maintain contact with the world. But that isn’t under Apple’s control either; that is 100% dependent on how near your connection (tower) to the network is to you.

So why didn’t I have any battery issues with my iPhone 13 Pro Max? I’m doing all of the same things I did on my 13 as I am with the 14. And this is a repeated comment from pretty much everyone on this thread but maybe 2 or 3 of you. The logic just isn’t there I’m afraid.

Was your iPhone 13 running iOS 16.1?

When I received my phone, I restored it from my iPhone 11 and this was apparently the issue

• I had to completely reset my iPhone 14 Pro after syncing all its data to iCloud

• I then did the setup again but WITHOUT restoring an iCloud save (I set up the phone without connecting my Apple ID)

• Once the phone was set up I then connected to my Apple ID and synced all the data

• Had to download all the messages, download all the apps from the App Store (they are stored on your profile to find them easily)

• Finally MAGIC HAPPENED !! Left my phone overnight on my stand table and lost about 5-6% of battery

• I had heavy usage of the phone while restoring the data and the battery didn't drain nor did the phone overheat while charging

When I received my 14 Pro Max, I restored the backup made that morning of my 13 Pro Max, and I have zero battery issues.

I'm glad you found a solution, but whatever issue you had is by no means universal.

I didn’t say it was universal but as many people in this thread are reporting battery issues like I experienced they might have the same issue as me. Better try to get rid of any corrupted save and just sync the data right from iCloud server !

Dear Lawrence, I'm sorry but YOU CAN leave your phone without charging overnight and you actually should if your battery is not below 20% as you will use one more charge cycle than necessary and then shorten your battery life :)

That is a false statement. Apple recommends charging your phone at night with Optimized Battery Charging enabled and does not suggest it should not be charged unless the battery is below 20%. A charge cycle is not determined by the number of times you charge. It is determined by how much charge is needed to get back to 100%.

You should charge you phone at night with Optimized Battery Charging turned on. Machine Learning is used to recognize your schedule and ensure when you awaken in the morning, your phone is charged to 100%, but it will not keep your phone charging all night. Instead, it will stop your phone at 80% and then charge it the remaining 20% in time for your new day.

If your iPhone is at 80% when you put your phone on its charger, with Optimized Charging on, it will remain at 80% until before you get up, where your phone will then charge to 100%, just in time. You will have charged your phone 20%. That is not a battery charge cycle. It is 1/5th of a battery charge cycle. In other words, if you followed the same routine and your phone was at 80% when you put it on the charger, it would take 5 nights of charging to equal ONE battery cycle.

Hi there,

I have also a brand new iPhone 14 pro and I am facing a bad battery performance.

I use my phone with 3hours screen on time before reaching 50% battery..

A colleague of mine has the same phone and can use 3hours his iPhone before getting…… 80% battery remaining !

He used his backup. On my side, I have made a fresh clean install without installing too much apps, also I don’t’ have photos (all on my NAS) and not so much files so indexation should not be the root cause.

The problem should not be the phone because my battery performance is the same as on my iPhone 13…

I have tried everything, install as new, restore with DFU mode, disabling some features but nothing to do.

I really do not understand.

I've been up since 8:00 AM this morning. While I haven't done more than answer a few texts, read some emails and surf the net a couple times, my battery at 6:00 PM is 94% remaining. This 14 Pro Max battery is nothing short of AMAZING.

Since I also switched to iPhone 14 Pro from an iPhone 11, you should really try setting up your phone without the backup from your iPhone 11 !

Reset it, set it up without your Apple ID then connect one phone is set up you sync back your data !

You should be good to go 👍🏻

The key is “low signal.”

If you’re in an area with low signal, your phone will use a lot of battery to communicate with a cell tower, and even more if it’s 5G, both conditions your screen shots indicate.

So this doesn’t strike me as particularly strange, as your phone was probably trying to sync contacts over 5G and was having to turn up its radio to high power to do so.

75% health after three years is incredible battery life.

Again, expected health drop is around 1 - 2% per month, and if health falls below 80% within one year of purchase, Apple will replace the battery under warranty.

Apple cannot and will not fix normal.
