Hello. I am planning a bicycle trip through Europe, sleeping in the wild. I only want to use GPS for tracking my route (Strava app), thats all I need, I will check my e-mails and messages only once a while, otherwise I will have airplane mode constantly on to save battery.
What I need from you are some recommendations on how to get the most of the battery. As I already mentioned, the GPS will be on for some 12 hours every day, but that is all I need, no cellular, no Wi-Fi. How about Android versions? Which ROM was the most battery efficient? How to make sure nothing useless is running in the background? I sure will take a big powerbank with me, but I only want to recharge it if really necessary. Thank you for your suggestions
