Other Are there any rumors on how much RAM the iPhone 13 will have for the non-pro models?

I'm pretty convinced RAM would stay the same as for the 12 lineup.

Keep in mind the 2 extra GB of RAM of 12 Pro are used for computational photography. Even a power user should not be impacted between 4 and 6 GB RAM. iOS is extremely efficient on RAM usage and before 6 GB add a perceptible boost in speed / confort beyond very specific cases (computational photography) you can wait 2 years minimum easily IMO. You will probably consider another phone at this time.
Don't get me wrong extra RAM is always cool but improvement are easier to notice on different specs IMO (battery capacity, refresh rate, optics, modem efficiency etc)

Hmmm… I don’t know how true this is but I have to say I am seeing more Safari refreshes on my 11 Pro Max with 4GB on iOS 15, that could be just down to it being on Public Beta and iOS 15 still needing more optimization, but yeah, definitely see RAM suffering a little now. On the other end my 2020 iPad Pro on iPad OS 15 Public Beta seems to be great with 6GB RAM not seeing much difference on it from iPad OS 14.

Take that with a pinch of salt, this is a Beta right now.

With the above being said it’s not like my 11 Pro Max is unusable, it’s absolutely flying through the UI and seems to run “lighter on its feet” outside of the Safari tabs dropping more and battery life on iOS 15 Public Beta 5 seems better than on iOS 14.7.1 in my experience.

Actually, we may not even need to wait 4 years for another spec bump. It may come sooner. Apple has consistently increased RAM every 2-3 years on the base models since the iPhone 4s:

iphone 4s: 512 MB RAM
iphone 4S: 512 MB RAM
iphone 5: 1GB RAM
iphone 5s: 1GB RAM
iphone 6: 1GB RAM
iphone 6s: 2GB RAM
iphone 7: 2 GB (plus has 3GB)
iphone 8: 2GB (plus has 3GB)
iphone X: 3 GB
iphone XS: 4 GB
iphone 11: 4 GB
iphone 12: 4 GB (pro has 6GB)


iPad pro lineup:

1st gen: 4GB
2nd gen: 4GB
3rd gen: 4GB or 6GB
4th gen: 6GB
5th gen: 8GB or 16GB

iPhone 15 with 8gb ram 👌😁🤤

Another thing to keep in mind is given the focus on the camera this year (video portrait mode), I think that lends itself to a RAM increase.

We're pretty close to launch so I'd expect Kuo to tell us at any time in the next few weeks.

If they finally make the jump to LPDDR5, the minimum size should be 6GB (IIRC Micron does have modules at that size while Samsung at 8GB, neither have less than that)
