I currently own a iPhone 15 Pro that is two years old and it has 820 charge cycles and 88% maximum capacity, I got to say in terms of battery life, the 15 Pro was not great and my drain rate with continuous usage on like ChatGPT is 1% for every 3-4 minutes or 10-12% per hour. This is not new since with every iPhone I have owned XS, 11 Pro, 12 Pro and 13 Pro, the 15 Pro is still not great but people keep saying the 15 Pro's were not good for battery life, but I wonder if that is universal and that I have a flawed model? When I check the battery usage, the statistics show very typical % drains for the timing I have used those apps in the day. Should I upgrade to the new iPhone 17 Pro? Will I see much difference between my 15 Pro and the new 17 Pro or should I just replace the battery instead? For me, I use my device a lot through out the day, sometimes for 2h window sometimes. The main issue with Apple's advertising of battery life is that for real world usage, it's far less than what it shows. They say 23h of video playback but that is just without sound or anything else running, in real world, it is more like 5-6h at best. With location services, Google's unfortunately power hungry apps and the fact that the 15 pro seems to get kind of warm sometimes just by charging or multitasking makes battery drain far faster than what expect from a phone. Yes better than the olden days but still not quite there yet and today apps are heavier now which can sometimes partly offset battery gains. Overall, I do want peoples advice, will I see a massive battery improvement with the 17 Pro or would it feel only modestly better? Battery life seems to vary heavily by usage. I am not upgrading for speed, but rather for battery and efficiency. In the mean time, I wonder if disabling all location services widgets in the widgets page could help?

Jk. I would imagine the battery life is better. I have a 15 pro and it's horrible. Down to like 60% by 10am. I imagine it would be better due to better heat dissipation. Heat is the enemy of battery life.

That said it's a huge downgrade in terms of design and elegance. The 17 pro line is... how do I say it... a laughable joke of ugliness

My Natural 15 Pro with 90% battery health lasts about 36 hrs in between charges (down to 20%). Beautiful phone especially the brooklyn grey colour and titanium frame. Nice and compact so comfortable one handed use.

My 17 Pro (UK version with 4,000 Mh) lasts about 60 hrs in between charges, sometimes 65 hrs to get to 20%. Significantly better battery life, the best ive ever had in a phone actually. Cameras are excellent also although the 15 Pro is very good.

Yes downgrade from titanium to aluminium in terms of premium look/feel but the 17 Pros still look good in my opinion especially natural silver. Also its a bit heavier and fiddly to use one handed but still possible, and the slightly larger 6.3” screen is a bonus (improved screen to body ratio).

I think the battery life is greater on the 17 Pro Max vs my iPhone 15 Pro Max. I charge about once per day now, whereas on the 15 Pro Max i'd charge 2-3 times per day.

I used to have a 15 Pro Max and updated to the 17 Pro, I find battery life is about equal to the 15 Pro Max.
 
Hey man, I feel you on the battery woes—my 15 Pro was the same, draining like crazy with heavy app use and getting warm too. Yours at 88% capacity after 820 cycles isn't terrible, but yeah, the 15 series wasn't stellar for battery universally; some units were worse due to early iOS bugs or hardware variance.
 
I went from a 15 Pro Max to a 17 Pro Max and the battery life has been significantly better, though I did enjoy good battery life on my 15 PM but the 17 PM has taken things up significantly in that department.

I imagine the 15 Pro to 17 Pro will be even more significant given that at the very least the 17 Pro has a battery that is 724mAh larger than 15 Pro’s, or in the case of the eSIM only 17 Pro the battery is 978mAh larger…this along with much better cooling should have you in a much better place.
