To parody Angelica from Rugrats: If you have to ask, don't.
Resist the FOMO. Even 27.0 GR will have some bugs that just ruin some people's day. It is crunch culture at Apple every year to finish this by the time the new phone launches, but it won't be until 27.1 or 27.2 that I would recommend it for 95-ish% of users.
That said, I don't practice what I preach. But I also have a Pixel 10 Pro as my primary phone and this iPhone 17PM is just for beta testing and nothing on it is important or will be missed if something goes awry.
 
I've been running the dev betas for years on my main/only device.

Apart from once (I don't remember if it was iOS 14 or 16) when IMAP mails broke on DB1, and I rolled back, it's been fine.

But then (a) I know how to roll back and (b) if I'm without a working phone for a day or two it's fine.
 
And logs can help developers find and fix bugs. Participating in a beta without logs or feedback is pointless.
Everyone decides how and why they run a beta, and saying it’s useless without logs is a bit shallow.

A lot of people just want early access to new features. Others write articles or comment on sites like MacRumors, which Apple definitely monitors for general sentiment and widespread issues.

Even for those who do report bugs, wanting to keep analytics turned off is completely valid. If you actually look at the logs available on your device, the amount of data being continuously collected on a beta profile is massive. You can easily choose not to deal with that constant tracking while still using Feedback Assistant or choosing to send a one-off crash report when an app crashes.

At the end of the day, a beta needs all kinds of testers. It’s not just about providing raw diagnostic data; it’s about real-world usage and feature feedback, too.

Like some others here, I've been running the dev beta on my primary iPhone since it first dropped -- but this is a bit of an exception to my normal patterns. Usually I wait (ahem) patiently until the public beta drops before dipping my toes in the water.

Fortunately, this hasn't been a bad experience for me at all; I got the chance to experiment with the new Siri a little bit before I would have otherwise, and I have seen very little instability overall.

But yeah... the battery life has absolutely been affected... and the new battery icon does not impress me. (Still worth it.)

For the first time since at least 8 years I’m considering to update to iOS 27 beta on my iPhone 16 Pro.

However, before I do that, I wanted to ask people out here, how has it been and are you folks running it as your daily driver? Have you seen any specific issues with apps for example banking apps?

I've been using the developer betas on my main iPhone since db1, and I think it's pretty stable, for the most part. (See my other response above, also.)
 
Using it on my 16 PM that I use for work with no issues other than “okay” battery life. Actually it’s far more stable than iOS 26 when I moved to 27b3.

The only thing o don’t like is the “instant search” that uses Apple ai …the options are weird. Never gives a website just lists text and apps that have the same search criteria.

I am on iphone 11 main device. And ios27 beta 1 is lot better than stable 26 versions. Everything is improved and more stable. Battery life is amazing too. Just very few keyboard glitches (must be related to liquid glass transparency I guess) and some very minor ignorable glitches. Which are lot lesser than what I had on ios26.
 
Installed on my M4 IPP (which is my only one, so I guess it's my main one *smile).

It's really fluid, and works well. The interactivity with the Pencil Pro is surprisingly nice.

Staying on 18 with the 13 Mini until 27 is released, and matures.

What made you switch this year?

I did the same. I’m usually cautious, but I couldn’t stand another second of iOS 26 glass or overall design.
 
I installed the 27 beta on my main iPad. But I only have one iPad and it only stay at home.

However, 27 beta is quite stable for now, even for Developer Beta, there's very little crash and heating issue to me.
