I came from Android, always had phones with big screens and was quite used to them, so I went straight for the Pro Max size to get a better battery life.My wife has the 12 max, she has a nomad brown leather folio, never complained once about weight/size.
I have the 14 pro and battery is no where near as good as the 13 max I had.
And the battery life is great so far, the phone lasts for the whole day without any issues even though I don’t fully charge it.
But it does feel really heavy for me, especially when I use it with one hand or for a long time. I have never had a phone THAT heavy before. But apparently it’s about 240 grams, which is indeed pretty heavy.
