Hello,

I’m currently on the latest version of iOS 18 and I’m planning to update upon iOS 26.1 release. For those who have the iPhone 14 Pro, how’s iOS 26 treating you in regards to performance, battery use, and heating?
 
There is no going back, so consider what features are in iOS 26 that you will use regularly. Is there something you see as truly beneficial or do you just have FOMO because there is a new OS with a new look? Go to an Apple Store or Best Buy and play with a phone running iOS 26 for a good long while and make sure there are no concerns about Liquid Glass before making a decision.

There has been coverage that iOS 26 uses more battery than iOS 18. And if you have to reduce transparency to make the phone more accessible for you, that will provide an even bigger battery hit. Since you said you are on a 3-year old phone, are you still on your original battery? Are you well above 80% battery health? From what I've seen, the slowdowns for low health make iOS 26 pretty painful to use, but if you have recently replaced your battery then it should perform reasonably well. (My wife has a 14 Pro with 79% health. We downgraded it back to 18.7 during the beta cycle for this reason.)

I ran iOS 26 on my 14 Pro since the first beta. The performance was just fine and I had no issues. I was already on my second battery, so I traded it in on the 17 Pro.

I had iOS 26 running on my 14PM from beta 3 through to the final release and it was absolutely fine. By the time the final release came around performance was great, battery life was not noticeably different to iOS 18 (84% health), and I never noticed any heat issues.

It works very well. The most surprising thing for me was the battery life, (I have 81% battery capacity already from iOS 18) since iOS 18.5 up to 18.6.2 the battery discharged so quickly even when I didn't use it that there was definitely something wrong with the software but I blamed it to the battery capacity. With iOS 26 this behavior disappeared. Heat problems never found, but this since its purchase in 2022

My battery life is 87% for a 3 year old iPhone.
