Optimizing Smartphone Battery Life for Climate Monitoring Apps

I've been experimenting with using my smartphone to monitor climate patterns, and one thing that's become clear is that battery life is a major concern. When you're running apps like Dark Sky or Weather Underground, which rely on constant location tracking and data updates, your battery can drain pretty quickly. I've found that using a phone like the Samsung Galaxy S21 Ultra, with its large 5000mAh battery, helps to mitigate this issue. However, even with a big battery, it's still possible to run out of juice if you're not careful. To optimize battery life, I've started using a few different strategies. First, I make sure to turn off location tracking when I'm not actively using the app. I also try to keep my screen brightness turned down, which can make a big difference. Additionally, I've started using a portable battery pack, like the Anker PowerCore 20000, to give my phone a boost when I'm out in the field. One thing I'm still trying to figure out is how to optimize my phone's settings for climate monitoring. For example, should I be using a low-power mode, or is that going to interfere with the accuracy of my readings? I've also heard that some phones have a 'high-precision' location tracking mode that can be more accurate, but also more battery-intensive. Has anyone else had experience with this? What strategies do you use to optimize your smartphone's battery life for climate monitoring?
