A new leak has now revealed some key details of the OnePlus 15T. While the compact phone is set to retain the 6.32-inch size of the 13T, it's now been tipped to arrive next year with a slew of improvements. https://www.notebookcheck.net/OnePlus-15T-New-leak-outlines-planned-upgrades-for-next-gen-compact-flagship.1051100.0.html
These features are what the 13T should have had. But it is still good news. Hopefully they will offer this in the US or at least have a global release. I really like the battery sizes.
As a bonus, these huge batteries don't need daily charging, which uses less cycles vs the Samsung batteries (my beloved S23 for example). So they have a much longer lifespan.
