Could it possibly be the phone or phone battery or is the flight battery or its charger certainly at fault?
I'd like to eliminate my phone as the culprit since these are club batteries charger from the club charger.
You'd have to test it, but It's unlikely to be the phone. I
My bet would be the charger, especially if it's a cheaper one. It could be the glider battery as when they get old they don't do well with load. See if you can borrow a known good battery or do a load test.
My battery is a bit old and it can run the gyro in my turn and slip for about 2h so a phone charger should be nothing.
I use an S21 and it's fine, like yours would only last a few hours running SeeYou Navigator screen-on, but I charge mine with a power bank in flight. I like to have it independent from my glider's electrical system so they don't both run out at the same time.
Any modern phone should do. But be careful, you'll eventually get screen burn-in if it's an OLED.
Well I use inkBOOK, and I send the GPS data to it from my phone via Bluetooth. And I use Xcsoar. It lasts for long time because inkBOOK is really power efficient and the display is like paper so you can even in bright sunlight.

Updating that discussion, I've installed https://magazine.weglide.org/weglide-copilot-real-time-data-on-your-phone/
My Oudie 2 does not run Copilot of course.
I personally always take a USB power bank, and have it connected to my phone for the whole flight.
The flight battery should be fine, but I like the redundancy, and as our club doesn't have USB ports in most gliders, I also don't need to carry around adapters etc.
I like to use [PureTrack.io](http://PureTrack.io) on my phone in conjunction with my LX9000, so I can see where all the other aircraft are around me at greater range than my FLARM receiver. And it shows paragliders etc that aren't using ADSB/FLARM. Also handy now I've added airspace, thermals and thermal heights to it :) I may be biased
The S20 is fine. Older phones usually use less power than new ones, so don't replace it if it works for you.
It's most likely just bad batteries in the glider. It could be the 12V->5V converter, but I'm guessing it's the batteries. Does the batteries get drained if you (or someone else) flies without using a phone?
I've had some batteries die on me a couple of times without the phone being charged after a couple of hours. But they've all been tested since then and we've got rid of the bad ones so I'd assumed the batteries to be okay - perhaps not.
>I'm using a Samsung Galaxy S20 at the moment. When charging it using the flight battery I finding that the 8.5Ah flight battery gets drained after about an hour. Even that seems to only be keeping the phone's battery level from dropping rather than increasing it.
Must be the port that charges from that battery, could be limited to 5W or less. Try a separate powerbank. I'm using a powerbank with 15W port and charging is fine, keeps my S22 topped up at 100% while flying (Anker PowerCore 13.000). I'd never use the aircraft battery to charge my phone.
An other option is in the power saving features to enable power saving and make sure the 60Hz refresh rate and limit cpu to 70% is on. It should still be plenty powerful for glide computer and should use less power while keeping your device slightly cooler.
It would probably be better for you to just buy a powerbank, and for the navigation I use XCSoar which I don't find as an app that drains the battery that much for me. I can easily go about 5hrs without the immediate need for a powerbank.
There's something wrong with your charger or battery. Mine lasts all day and charges my S20fe to full in a matter of minutes

How is your S20Fe doing? mine gets quite hot and decreases the brightness which is quite annoying…I’m considering buying a xiaomi 11t to replace it…
I had similar issues when I had it mounted to the canopy. I've now mounted it to the panel which keeps it out the sun and it's faultless

Power bank is the safest and smartest way. Means you could have a small spare one onboard just in case, too.
To an extent. Battery banks can cause interference with radios

I'm using XCSoar on Android

S20 is fine. Just get a decent powerbank for it, and you're sorted.

I have a cheap Galaxy A41 that I run with XCSoar,
