Lost Ultra Stamina on Xperia XZ2 after update to 10

Please reinstate Ultra Stamina Mode or provide option to go back to Version 9.  We should be made aware of all changes before updating the system. We should also not be forced to update system software.  Work with your customers. There are many options for cellphones these days.  I prefer Sony over many brands, but am willing to switch if this is how you treat your customers. I hope you truly feel how much people in your forum just want the issues resolved. Looking forward to hearing a resolution not an excuse or scripted response. Thank you for your time Sony!
