I used my previous phone pretty much everyday as GPS device in the car and normally I used to charge it while driving. Of course it didn’t charge as fast as at home but it was enough for me to go. Now that I made my /e/ flashed S9 my daily phone, I made a 1h15min drive with my /e/ S9 charging in the car (my radio has USB plug) with the GPS on (I use Osmand), and the battery not only didn’t charge but it drained 20 % during that time
Someone with /e/ Galaxy S9 (or stock ROM) experienced something similar? Is the GPS or screen usage soo huge that it prevents the phone from charging in the car? I will try it some more days to check if this behaviour continues, but unfortunately, if I can’t solve this problem, I will have to reverse to Stock ROM and return the phone, as I need it to be able to use it as GPS and charge it in the car every day… It would be great to know if other Samsung devices (S7 Edge) behave the same, because battery is quite an important aspect for me and wouldn’t mind switching to /e/ in an S7 edge (600 mah more), even if its an older phone, if that gives me less battery drain.
