So what's your experience in terms of speed and battery life with iOS 27 on the iPhone 13 so far? I have a 13 mini, and I still haven't gotten over the (perceived) shorter battery life with iOS 26.

Upgrading the battery on my iPhone 12 Pro has been a fucking revelation. I just don't run out of battery any more. I'm sure Apple was telling me it was only 20% degraded or something too, but I would strongly, strongly recommend this if thinking about battery life is currently an issue for you.

  That could be a factor for sure, but this iOS upgrade basically broke mu iPhone as switching between apps got noticeably slower and sometimes the UI gets stuck for a second or two especially when switching between the camera and other apps. I'm so sorry I gave in and installed it.

  I think it's different for mini owners. I upgraded my battery in march of this year and its already at 89%, I blame ios26 frankly.

    Oof! Mine is still the original one, and it’s incidentally also at 89% after maybe 3.5 years of being my daily driver.

I would say bettery is about the same of iOS 26, but mine is quite cooked (78% battery health) and I have to replace it. Performance is for sure better. Not as much as I expected (I expected to notice it everyday), and I can't give you a number, but I remember that I noticed stuff being faster the first couple of days that I installed the beta, but now I got used to it

  I run iOS 18 and have no problems with my battery, it is at 73%. iPhone 14 Pro. Don't think I'm going to install 27 either.

    I reviewed the battery test results for iOS versions 26 (26.2, 26.3, 26.4, 26.6) and 27. The comparison covered the iPhone 14 series and newer models. The batteries in each model retain their charge 10–15% less effectively on iOS 27.

      Thanks kind stranger, genuinely appreciate the info. I had my suspicions.
