Recommendation for a phone to use in the mountains

Hi,
I need to replace my old phone. My requirement is a good battery life. What I am seeking of:
- 3 days without recharging in relatively cold conditions, let say below 50 WITHOUT powerbank
- From it at least one summit day close to freezing level
- From it at least one day writing a GPS track. All other days occasional use to make pictures
- No connection is needed. Can stay in airplane mode
If someone used a phone tested in EXACTLY same or worst conditions, I would like to hear recommendation. All other comments will be IGNORED.

Does not exist.

As Allen said, the phone you asked for doesn't exist.

That said, the phone that I have settled on is a Samsung Galaxy Flip 6.

I keep it mostly turned off when I'm in the backcountry, and only turn it on to occasionally check texts and check maps. Battery life is good for multiple days when I'm using it in this manner.  

The folding form factor makes it much more compact and small than a typical phone.

I use T-Mobile, so I have access to Star-Link satellite texting even when I'm outside of cell range.  

Camera is quite good, and it's waterproof.

There's a new version out now (Flip 7) that I'm sure is an improvement on my Flip 6.  

I think you could possibly get close with extreme battery saver, allowing only a handful of apps.

You'd have to keep it close to your body to keep temp up, and maybe only get 8-10 hours of GPS, but otherwise very minimal use you could maybe get there. My old pixel 5 only drops 10% or so in 24h with extreme battery saver. No GPS or freezing temps though 

Get a smart watch to record the GPS track and have it sync to the phone.

I am sorry, you are all wrong.
My Huawei Mate 10 did exactly what I described.
The screen cracked, I need to replace it.

So, why post your question if you already know the answer?

Ignore everyone else and talk to yourself.

Various tracking apps is very different amounts of power as well as various levels of frequency of recording points. Using all trails, my pixel 8 typically uses that 5% battery per hour when recording GPS tracks in airplane mode. In extreme airplane mode I think it uses less than 15% per day. With occasional map and photo usage. So depending on whether you mean by day ( 24 hours  or just 8 hours) of recording, this might meet your needs. I usually keep my phone in an inside pocket, so I haven't noticed extreme differences in battery duration in close to freezing weather.

I do hike with a small battery pack since it can be relatively easy to accidentally either leave the screen on when I put it back in my pocket, or forget to switch to airplane mode.

Screens can be replaced on most phones. In my area it's $100 for regular glass or $150 for Gorilla glass.

Having a freer minute decided to do internet based research, also known as "google for stuff"
Can you believe that you could get a fully featured Android phone with 33000mAh battery?
Here is link to manufacturer's site - https://oukitel.com/products/oukitel-wp100-5g
Apparently, this is not vaporware - https://www.techradar.com/pro/this-swiss-army-knife-of-rugged-phones-has-the-largest-battery-ive-seen-on-a-mobile-device-and-the-built-in-projector-is-cool-too
And, according to this youtube video, it is, well, something different!
Same company sells other models with large batteries

This is perfect! You don't even have to print out the topo, you can just use the built in projector to cast it right onto the face of the climb.

I am just here to get IGNORED..........

Ignore UNCHAINED   

Mark P - Various tracking apps is very different amounts of power - very true, I used Gaia before, but switched to CalTopo. Maybe it consumes more, I don't know.
Ken Tubbs - Screens can be replaced on most phones Yes. Maybe I will just replace screen on my old phone,
Kai Larson - why post your question if you already know the answer The phone is old. I thought maybe I can have a new one, but want as good battery as I used to have.
Milan Damjanac - Thank you for the link. With 867 g Oukitel WP100 Titan is a bit heavy.
Daniel M - Get smart watch - I want to have bigger screen to look at the map. Also - pictures.

I agree smartwatch is the way. My Garmin Fenix has a pretty good map on it and then you can use a cheap phone on battery saver for pics

Instead you can simply carry 3oz more battery and use whatever phone you want.
