iOS 27 Battery Life tested on a daily driver iPhone | iOS 27 Battery Drain reviewed after updating 15 unique iPhone models to iOS 27! With iOS 27 Beta 1 we know Apple has promised 30% faster performance, but there were also rumours that the battery drain issue in iOS 26 would be fixed as well. These are not just rumours in iOS 27. The battery life is so much better on iOS 27 on my personal iPhone 15 Pro Max than it was on iOS 26.5! Moreover, all of the 15 iPhone models I updated to iOS 27, including iPhone 11, iPhone 12, iPhone 13, iPhone 14, iPhone 15, iPhone 16, iPhone 17 (I updated at least 1 device of each major iPhone model including Pro’s, Pro Max, Plus, Mini), and not a single one of them had excessive battery drain after freshly updating to iOS 27. I showcase the older iOS developer beta 1’s and just how much worse they were compared to iOS 27! I hope you enjoy.

  1. I think Apple will screw it up in the next updates and this beta battery strength is a total coincidence

  2. Can you please suggest me the way to downlod old freeform app from ios 26 pre creator studio version I don't like new one which is preloaded with 26.5 pushing creator studio subscription I was able to download all other older I work apps for iPhone except this please suggest me way to downgrade that will be really helpful 😅

  3. so i have the beta 27 ready to download, have my phone backed up im on a 16 pro max and im wondering is the update worth it or should i hold off till later

  4. Can anyone tell me if there are any problems on 15 pro max with 27 beta? Is it save rn? Is it risky?

  5. bro im on iphone 14 pro is the battery better on ios 27 beta 1 than its battery on ios 26.5? i have 80 pc battery health i need battery improved

  6. Did you look into the bricking situation? I obviously don’t want to try it out on my phone.

  7. I really enjoy your content. Just a small suggestion: you might want to try LogCam for your iPhone videos. This app records in HEVC with much less image processing than Apple’s native camera app, resulting in a more natural and detailed image. Originally, it was designed to capture footage in RAW before converting it to HEVC, which is part of what makes the image quality so impressive. In my opinion, the results are not only better than Apple’s default camera app, but they also outperform Blackmagic Camera in terms of image quality and natural rendering.

  8. Hello great video! a question. Do you already have the new Siri AI on any of your devices? Since June 8 I have been on the waitlist and the notification of the new siri has not yet received
