Yes, but my few year old Petzel headtorch uses 3 AAA batteries that weigh hardly anything, and I can carry spares at no cost, and it has multiple brightness settings where I generally only need the least bright light. And my camera, well it weighs a tonne but again i carry spare Li batteries that i can swap out when one goes flat.

I lust after a 645. But my present set up weights 2.5 kg - includes spare battery, tripod, 28 to 600 equivalent lens ... and costs a lot less...

Perhaps mobile phone batteries have improved, but not in my experience. Obviously for day walks they suffice, but knowing how much some apps can increase battery use, I imagine you'd be charging through the charge rather quickly!

The GPS will still work fine.
If you want to save even more battery, turn your phone completely off and accept it will take a minute or so to restart it when you need it.

EDIT: Oh, yes... and you can get full-featured map/nav apps for a 1-off payment of $5 or $10. That's peanuts! (There are also much more expensive apps, and year-after-year subscription apps, but as far as I can tell, they don't offer significant value over some of the cheaper ones.)

There's a massive difference in how much charge i have left in my phone at the end of the day when I'm using the app in the field vs a day in the office not using the app. Though it is a GIS with way more going on than a simple mapping app.
But I'd like to know more about the following -Son of a Beach wrote:If I'm going for more than 3 days, I'll carry a power pack that I can use to recharge the phone.

What power pack do you use? I know nothing about this area at all. How long does it take to recharge your phone in the bush? Also, on the fragility of phones, battery life can be affected by the cold, where i've found my phones are affected more than other devices.
Thanks for all the replies!
Son of a Beach wrote:Heh... don't use Field Maps as any sort of measure. I'm a GIS admin at work, and do a lot with Field Maps. It is not an entirely good example of how to do mapping/navigation on an iOS device. Don't get me wrong, it's an eminently useful app for GIS field work, but its battery consumption is more than it should be. I think the only app that is worse in this regard is 'Survey123' (also from ESRI).
A genuinely mobile-friendly app should not be engaging the location services of the device except when absolutely necessary. I don't know if this is Field Maps problem or not, but I do agree that it's not a mobile-friendly app in terms of power consumption.

It's been really handy for recharging the phone on medium to longer walks. I don't know how long it takes to recharge the phone. I plug it in when I go to bed (not every night), and when I get up it is charged.
Yes, temperature does have an impact on all kinds of batteries. I keep my phone in my (zip-secured) pocket during the day, where (hopefully) it remains a little warmer. I don't know what impact the cold has on the battery bank, but I've never had trouble getting the charges I needed out of it.
Actually, the power bank is a little smaller than my iPhone 13 (standard size, not plus size phone). It's about 5 mm thicker, though.
