A camping trip sounds awesome, but yeah, mobile browsers are absolute battery hogs! They run a ton of background scripts that just eat away at your percentage. I actually do a lot of fishing trips myself and faced the exact same issue. I switched to using a dedicated client app instead of a web browser because native apps store most of the heavy graphics locally on your phone. This means the app only needs to send and receive lightweight raw data, which saves an incredible amount of battery and bandwidth. If you want to keep your phone alive and bet on a weak signal, definitely grab the app from https://mcw-777.com/download-android It’s super lightweight, data-friendly, and perfect for when you're away from a proper charger!
