Many people, and I include myself, we have downloaded the First beta of iOS 26and, as expected, it is not as stable as we would like, because it heats the phones more than it should, or their battery consumption is excessive compared to iOS 18.
That is why we are all waiting for a second beta, that these problems solve in part, and that, in turn, add new functions and tools that we would like to try before anyone else, so we will see what the possible exit dates of the betas would be.
IOS 26 Beta 2 and subsequent date
Although this is approximate, since Apple does not guarantee dates, and will depend, in a way, on how good or bad the betas go, we can get an idea looking at the past, since every year it usually has some deadlines that are fulfilled quite well, and that we hope that they will follow the tonic during this period.
The first beta is launched at the WWDC, after the presentation of the iOS system and the rest of them, being available minutes after it, and that this year coincided on June 9.
The second, normally, we see it 2 weeks later, so we could talk about the fact that it should leave next Monday or Tuesday, that is, Between June 23 and 24although as we said, it could be delayed on Wednesday or even a third week (although it would be rare).
Subsequently, Beta 3 would come out, which normally coincides with the first public beta of the system, and the one that would give it another 2 weeks, since Apple's pattern is to launch at least the first 4 beta, with 2 weeks of differences between them, and from there, in the last month, do so weekly, correcting, minor errors.
Finally, The first week of September, we could have the final version of iOS 26that it will be the one that all the iPhone 17 carry, and that we can have available, after the presentation, although in principle it will be the same, so at that time we can download the beta, understanding that it is perfect and has no errors, thus anticipating a little to the rest of the users, and without running the danger they have in their beginnings, as we already commented.

And you, are you one of those who need to download the betas when they leave? Anyway, if you already have the first, unless you do a download and return to iOS 18, you will be impatient for the next ones, because the errors in the first are visible, and, although they do not prevent you from using your iPhone normally, you will notice that you have to load it more often, or that it heats up in excess correcting it.
In my case I have returned to iOS 18, and I hope, at least, to have a couple more. Leave us a comment with your opinion and experience with these betas, since, despite being the same, it often depends on the iPhone model, and does not work so badly, or so well, in all.
