Best Delta Settings for Battery Life
A handful of settings changes that meaningfully stretch playtime on a single charge, without hurting how games feel.
Overview
Emulation itself is light work for most modern iPhones running GB, GBA, or NDS cores, so the bulk of Delta's battery drain during a session actually comes from the display, haptics, and background features rather than raw CPU load doing the emulation.
A few toggles inside Delta's own settings, plus a couple of iOS-level tweaks, cut power draw noticeably without touching emulation accuracy or frame pacing — nothing here trades away how the games actually play.
This matters most on long commutes, flights, or road trips where a charger isn't within reach and a game session needs to last hours rather than minutes.

Good to Know
Low Power Mode (Settings > Battery) barely affects emulation performance for GB, GBA, or NDS cores, so it's safe to leave on for the entire session rather than just as an emergency measure.
A simpler skin with a smaller touch overlay redraws less of the screen per frame, which saves a small but real amount of power over a multi-hour session.
Closing other background apps before a long Delta session frees up thermal headroom, which indirectly helps sustained battery efficiency too.
