r/17ProMax

Hi everyone,
I recently got an iPhone 17 Pro Max, and I’m trying to keep the original battery as healthy as possible.
Right now, I usually follow the 20%–80% charging rule, because I’ve heard it helps reduce battery wear. However, I’ve also seen a lot of people say they charge from 20% all the way to 100% every day and still have excellent battery health after a long time.
Interestingly, my 11-inch iPad Pro (4th generation, M2) has been charged from 0% to 100% for almost 3 years, with almost daily use, and it still has 91% battery health. That makes me wonder how much of a difference the 20–80 rule actually makes in real-world use.
My goal is to keep the original battery in my iPhone for at least 3 years, ideally with 80% battery health or higher by then. If it drops to 79%, I’ll replace the battery. Assuming it’s still at 80% or above after those 3 years, I’d probably keep the phone for another 2 years before upgrading to a new iPhone.
So I’m wondering:
Is charging from 20% to 80% really worth it in the long run?
Or is charging to 100% regularly not as harmful as many people claim?
What charging routine has given you the best battery health after several years?
I’d especially like to hear from people who have kept an iPhone for 3+ years and can share their battery health and charging habits.
Thanks!

After using various cases from brands i the device kept feeling bulky and somewhat uncomfortable to use in longer sessions. And can’t figure out for the life of me whats a slim case that’ll preserve almost the proper build of iPhone 17PM ? Without the case the phone is quite awesome and great to hold although a bit slippery sometimes and the general fear of denting or scratching is there. I mostly used TPU cases, didn’t thought much about silicone coz they don’t age well, I don’t like clear ones to coz it shows fingerprints. Although im open to suggestions. Thanks.

I am thinking of upgrading for an upcoming big trip for the better camera. I am really a point and shoot person so all of the extra features may be lost on me, but I did play around with the zoom in the store and there is a noticible difference. It's kind of a spur of the moment decision as I hadn't been thinking of a new phone yet. Those that have one, what are your thoughts? Am I doing the right thing or will I kick myself not waiting for the 18.

For clarity: It's a big trip overseas and also a chance to see the eclipse, so lots of photo opportunities

Hello guys, i have the 17 pro max - Deep blue.

Was wondering, do you guys use cases or there are people who never use a phone case on these??

I am just curious if it is just me. I think iPhone 17 PM has it that all actions that I did just seamlessly on Android is now a headache on iPhone.
Simple copy and paste is a task every time and sometimes a matter of fortune. Correcting text is too
Etc
I do not remember difficulties using my child iPhone 13 a few years ago. Not so many anyway
But now it is sad I can not use phone to do what I am doing with attention to the task itself without extra thoughts and efforts on basic typing and such

So, a few weeks back, I accidentally broke my front display. Even though the phone was still working, it kept stuttering and the charging port was super worn out, so I was really depending on MagSafe to charge it.

The battery was severely depleted, lasting only five hours on a single charge, leaving only 74% of its original capacity. Replacing the battery, screen, and charging port would’ve cost me more than getting a second hand 13pm.Besides, I’m not getting aftermarket replacement parts because I bricked my iPhone XR doing that 7 years ago.

So, I decided to bite the bullet and get a 17 PM. I still love my old phone and will definitely keep using it, but I reckon five years is a good time to think about getting a new one.

Hi everyone,
I’m currently running iOS 26.5.2 on my iPhone 17 Pro Max and I’m thinking about installing iOS 27 Beta 2.
For those of you using it on the same device:
Does Beta 2 feel stable enough for daily use?
Have you experienced any major bugs or issues?
Most importantly, how is the battery life after indexing is finished? Is it better than on iOS 26.5.2?
I’d really appreciate hearing about your experiences before I decide to update. Thanks!

I bought my blue 17 pro at launch and absolutely love it. My only regret was getting 256 gig. My husband’s 14 pro is dying, so we ordered a blue 17 pro with 512 gig of storage. He will take mine and I get the 512. Couldn’t beat the trade in deal. 🩵💙

Edit: sorry, I left off the question. Anyone else sorry they did not get more storage?

recently got my 17 pm. Any case recommendation? Thank you so much!

Trying to upgrade without paying the full new iPhone price. I m not in a rush, so second-hand or refurbished is fine if it comes from somewhere reliable.

Mostly worried about battery health, hidden damage and getting stuck with no return option. Where would you look first?

How much would you pay for an IPhone 17 Pro Max 512Gb with a replaced screen from an iCloud locked device and also a replaced frame? Battery health is at 100% with less than 100 cycles. I found it on marketplace and I was thinking about asking for a very low price or maybe I shouldn’t even deal with this kind of device with such crazy repair history

Has anyone else noticed this?
I recently upgraded from the iPhone 13 Pro Max to the iPhone 17 Pro Max, and I love it so far. The only thing I’ve noticed is that the volume seems much lower when I’m using my AirPods Pro.
I usually listen to music at a very low volume. On my iPhone 13 Pro Max, I only needed about two volume bars, but on my iPhone 17 Pro Max, I have to turn it up to almost halfway to get the same listening level. It’s not a major issue but I was just curious if anyone else has experienced this or if it’s just me.
