a few iPad questions

Hi all:
I will receive my first ipad next week, after using iphones for years. Hopefully someone could answer some questions:
I have read that sighted users can use new ios gestures: open notification screen, go to the home screen, I mean, as you would do in an iphone with face id. Is it possible to use new voiceover gestures as well, sliding a finger from bottom, instead of pressing the home button"It is an ipad air, for the record.
What are yor experiences using the braille screen input on a bigger screen?
Your experiences with the battery life?
And finally, any remarkable differences between using an iphone vs using an ipad. FROM a voiceover perspective, obviously: tips, advantages, disadvantages, suggestions or whatever...
Thanks in advance and excuse my english.
