It was unreliable piece of &^*&^%&^, I had to teach it my fingers every week during the cold season (which in my country is close to 7-8 months) and during summer I had to do it only once a month maybe - during winter the air gets colder fingers dry out especially if you have allergy (and I do).
And it was slow, I did unlock with pattern faster.
As for battery, I don't feel that it is poor in Pixel 4 (I ditched Pixel 3 as soon as the preorders for Pixel 4 started), but I use wireless charging all the time, I have it at work and at home, so my phone is almost always at 100%.
And now I'm puzzled, why did they bring back fingerprint scanner in Pixel 5? Apple didn't bring it back after they jumped the face unlock wagon.
Not to mention inferior CPU/CPU in Pixel 5, it looks also worse than even in Pixel 3, but the price is still premium.
So basically now we get a Nexus quality phone with Pixel price point.
Otherwise I agree, my battery life feels fine, and the upgrade to the 5 doesn't seem all that worth it.
Oh and a trivia about Pixel 4 Soli (which is a gimmick, nothing more), I was wondering why my music suddently restarted so frequently when I was in car.
And I found out why after few days - since a week we have a lot of rain, so when I drive I have windscreenwwipers and this was somehow being picked up by soli (when my phone was mounted near windshield, but not that near) :)
But "age of facemasks" depends on country. In mine I need to wear masks only in stores, public transport.
But in those places I also need to wear gloves, so both ways of unlocking phone are unavailable to me.
And still, Apple manages to keep their unlocking mechanism.
I live in the Canadian prairies, so cold + long winters are no stranger to me, and the fingerprint just always worked. The face unlock fails more in the winter because I'll be wearing a scarf or headcover which renders it useless. Heck, even in the summer it fails frequently because I'll have sunglasses on
