I have a 15 Pro 128GB and I can no longer install betas with their sheer size and how much the current OS takes up.
- OS: 32.5GB
- System Data: 26GB
- Update: 22GB
That’s over 80GB just for iOS, which is almost 2/3 of the storage space. Annoyingly part of the OS is a 12GB reserve for updates but that doesn’t count for beta installs.
This is just getting way too bloated in an attempt to force people to pay for more storage. I’ve already offloaded a chunk of things to “the cloud” but that’s well beyond what I can keep coming up with.
My iOS 26 install takes 14.1 GB on a 14 Pro Max.
iOS 26 is 12.87GB on my 12 Pro Max. System Data is 38.15GB for some reason.
My install of 26 is only 12GB on mine (the rest is Apple Intelligence and install reserved space).The 26.1 Beta requires an extra 22GB of storage before it will even install. My guess is room to unpack and temp operations.
