the thread about the iPhone 17 prompted me to look at my iPhone 14 max pro battery max capacity and it shows it is at 77%. my phone is 2years and 7 months old...I have not really noticed any issues other than occasionally and by occasionally I mean not very often it will discharge pretty fast like go from 100% charge to under 50% charge in a few hours without being used and get pretty hot...again it has only happened a few times in the last year or so. It seems to have good speed surfing the internet etc....so that all said how important is it to have the battery replaced?
iPhone 14 battery life question.
- Thread starter jadmt
- Start date
The rapid discharge with heat tells me something is hanging in software and running the processor. It may be appropriate to plug it into a computer, do a full backup and restore. This will preserve all of your data (including passwords if you do the encrypted backup) and refresh the operating system and every app with fresh installations. You will need enough hard drive space to hold the contents of the phone, there are ways to use an external hard drive but it requires some terminal competency. A backup and restore usually takes care of those situations, unless you have an oddball rogue app.
The 77% doesn't mean much if you don't really tax the phones processor much. If you're happy with the battery life for your usage, you can let it ride until you're not happy. If you decide to use a really taxing app, you will notice a drastic battery drop and I believe Apple states it may impact processor performance to compensate for the battery.
Since you read the iPhone 17 thread, I'll make sure you saw my post, get Apple involved with a battery change when you're ready for it. It's $89 and if you have a store near you, it's a couple hour process.

You’ve got a 14, which means the phone is at least 2-3 years old. If your battery capacity is only 77%, it’s time to replace it. You can go through apple, like described earlier, or private as long as they guarantee using an actual apple battery. I replaced two of them during my run with my iPhone 8. It kept it going until I decided to upgrade to a 16.
Had a new battery installed at an Apple store last year. If you make an appointment you are in and out pretty quick. I wonder if you have a rouge app that is not closing. Like stated above a back up and restore might be a good idea. Or some 3 letter agency has wormed into your phone and is monitoring your oil purchases? 
Once you get below 80%, for most people, this will mean having to charge the phone frequently and that it will rarely make it longer than 12-ish hours on a full charge. It basically becomes a pain in the butt where you better not forget a charging cord with the discharging being a big unknown. As far as speed/power, a 14 is just fine - don't buy into the need to upgrade every 1, 2, 3 years. I'd replace the battery and keep going. Only do it at an Apple store though so that you get an actually Apple battery.
yup 2 years and 7 months or so old...
I feel the same about my 13 Pro Max. just hit 4 years as I got it the day it came out. Battery is at 87% and not feeling any need for a 17, maybe an 18, maybe not.
unfortunately I have 0 tech savvy....still think a micro wave is a passing fancy that won't catch on....no Apple stores in my area...have another repair place that says they work on Apple but are not an actual apple store.but doubt they have apple batteries...is there a way to manually go thru and look for the rogue app?
My iPhone 14 is 3 years old now and battery cap is at 88%. Ima ride her into the dirt.
My 14’s battery has minimal degradation. Then again I avoid charging up to 100% on a regular basis.
Look for Apple authorized repair places in that case. Apple will list them on their website if they are. Don't trust a store that tell you they are !
There's a menu that allows you to set the max charge level. I have mine set to 95%. You can set it from 80-100%.
Do you use a cable to charge your phone or MagSafe charger?
That's a lot of degradation. My iPhone 13 I just replaced for no reason other than getting a good deal on a replacement phone is still at 87% battery health and I honestly can't tell the difference in lifespan than when it was new. I mostly use wireless charging which is supposed to be worse because it makes more heat but based on retaining 87% at the 3+ year mark I think it's not an issue. I would think even 77% is still plenty usable, but it just depends on what you use it for and your access to a charger throughout the day.
You guys must barely use your phones. I replaced the battery on my iPhone 14 less than a year ago and it's already at 97%. The old one was at 83-85% and I could not stand the short battery life at that point.
I’m a heavy user and my iPhone 13, which I had for three years still had 89% (maybe more )left when I got rid of it in March 2025 I forgot the actual number. My wife Now at 3 1/2 years on her iPhone 13 has 87%.
I typically use charging cable. My wife uses MagSafe all the time.
My current iPhone 15plus was purchased March 2025 still has 100% I have charge limit set to 90% on this one.
MagSafe at home. Cable while driving my car.

And their work is guaranteed for 90 days. If something goes awry with the job, which can happen, they'll swap the phone with a white box service replacement unit (refurbished, new outer case, new battery). On devices that aren't serviced locally, like an iPad, those are straight replacements.
A service that a mall kiosk or indie shop will not be able to provide.
looks like this place is close and says they use actual Apple batteries. Anybody have good or bad to say about them? thanks.
