So far, the first beta of iOS 15.4 is running quite well on my iPhone 15 Pro. The battery was relatively warm for a while, but that has settled down now. Let's see how it performs in the coming days.
Got a tip for us?

@Pearsey rightly said..beta train is unpredictable !!
This!! Crazy enough in the short time I have been using the beta the battery has been great on my 16 pro.
They must’ve fixed whatever issues there were with WiFi calling on the backend, because the VZW Wi-Fi logo has come back to my status bar after not being there yesterday.
Thank god, I have horrible Verizon service at my house. And it’s better than the alternatives.

We've waited for 14 years. I guess another few weeks/months won't break the bank. Considering how behind they are, they need to get this right.
I'm in Italy and get a message that Image Playground will appear after downloading. Waiting for that to happen.
I updated via ipsw, we’ll see. My iPhone 16 PM has been so laggy on iOS 18.3 I swapped back to my 15 PM.
Can‘t get the writing tools to work properly on my iPad Pro and my iPhone 16 Pro in german. On the Mac everything is running fine.
Proofread ist working on all devices. Rewrite is only working on the Mac. On iPad and iPhone I only get a message that some writing tools features aren’t available.
Deactivating and activating Apple Intelligence doesn’t work. Resetting my iPad and restoring it from Backup doesn’t help either 🤷🏼♂️.

15PM and iPad Pro 11
OTA Update on both
Mail
Not seeing any functionality changes - same issues with badge vs auto update vs manual refresh - same ol’
Can now click on a Notification and it opens the actual email - nice
Notifications (banner) are not working - even after a hard reboot, only Lock Screen and Notification Center are showing
Podcasts
Banner notifications are finally working again however they get stuck and don’t go away unless swiped manually
Widgets - 15PM only
Borked my widgets.
Weawow Weather shows some funky language/symbol thingy
Outlook Calendar always shows “All done for today” even though I have upcoming appointments
Hard reboot and replacing widgets did not fix (see below)
Safari - iPad Only
Long lists in a tab stutter.
More to come as I get time. So far everything else I have tried is the same as 18.3.1

I’ve had excellent battery life on my 16 pro today. Hoping it’s not a fluke.
Same here. That’s the only reason I can think that they kept the two parts of it separated instead of one solid cutout. Really hoping in a future build they revert it.
I constantly read this but I don’t think there’s ever been anything clearly indicating this or solid proof. I’ve had betas with battery life as good or better as released builds, as well as betas with crappy battery life.
Beta is running pretty good on my 16PM. Image Playground, rewriting , notifications and everything is working great in German for me. What doesn’t work at all atm is Siri. Reply is empty, with or without logged in ChatGPT account. After a restart it’s the same problem 
Am I tripping or are the camera/microphone/etc access dots in the Dynamic Island now using HDR brightness? I remember this was rumored back when the iPhone cutout leaks were happening but I don‘t think they ever were HDR. They‘re quite blinding in dark mode actually.
Also they have a new animation when removed from screen. They now scale up and make a bloop instead of subtly scaling down while fading out.

as the first beta version it works really well, compared to 18.3.1 it's even better for me on 16P
That’s a very bad bug indeed. A showstopper for users of Siri. I use Siri quite a lot so couldn’t risk losing it.Beta is running pretty good on my 16PM.

If there is a 32% improvement in battery, I think there is possibly something else involved. Maybe an app was running wild in the background previously and it’s now been fixed.
Seems to be mixed experiences on beta 1 unsurprisingly.
Quite a lot of people having good performance and battery which is promising at this early stage.
A few show stopping bugs for just a few users - Siri not working for at least one. To be expected in beta 1.
A good first test release all in all but not to be risked for users who need their phones to work properly.
I’m excited to hop on maybe around beta 3. It’s good to have all the user feedback in this forum to make an informed decision.
Keep up the good work guys.
