OK... yes, there are many variables i.e., temp, age, model, etc., but in general how many days can you expect your cell phone to last if it is almost always on AIR PLANE mode? Just using Guthook during the day and if necessary to place a call temporarily take it out of Air Plane mode but right back when done. I have a battery pack but don't want to carry the weight and most times there is someplace to charge.
Next question.... is it better to turn your phone off at night and reboot in the morning, or does rebooting use more power than leaving it on airplane mode all night.
Driving north to do a sobo section from Gt. Barrington, MA to Hoyt Road, NY in two weeks and figure on five days.
Thanks for any comments, grunt
