I recently got my hands on an old-model smartphone and started thinking about how to optimize the balance between battery life and performance. Is it harder to strike this balance in models that don’t receive constant updates, or should we just focus solely on battery health? What do you guys look out for when using older models? Would love to hear your experiences!
How should I balance battery life and performance on older models?

I found the simplest way to balance battery life and performance on older models while discussing it with a friend yesterday: just as important as the settings you tweak are the ones you leave alone. I’ve been using my LG G3 since 2017, and back then, nothing could beat its 5.5" 2K screen—until I wanted to stop gaming on it. Dropping the refresh rate from 60Hz to 45Hz gave me around a 30% boost in battery life. With models that don’t get constant updates, you have to manually adjust performance settings; if you leave it on default, either the battery dies or the device overheats.
Battery health is crucial, but sometimes small steps make a big difference. I’ve made it a habit to discharge to 20% and recharge to 80% once a month, reducing voltage stress on the lithium battery. I also use Greenify to limit background apps—especially on older devices where the default optimizations just aren’t enough. In short, there’s that "sweet spot" you’ll find through trial and error, and you’ve got to keep tweaking until you hit it.
