Arknights Endfield How to Reduce Battery Drain and Heat on Mobile Devices

Reducing battery drain and heat in Arknights: Endfield is mostly about capping FPS, lowering a few heavy graphics options, and fixing phone habits like brightness and background apps. Use the settings and habits below as your standard mobile profile.

Core In-Game Settings to Change

These are the biggest levers for thermals and battery.

• Frame rate
  • Set 30 FPS for long sessions; this is the single largest cut to GPU load and heat.
  • Only use 60 FPS on strong phones and shorter sessions.
• Graphics preset
  • Use Medium on modern mid-range/flagship devices, Low on older/budget phones.
• Resolution / render scale
  • Keep at 80–100%; if big fights stutter or the phone heats quickly, drop slightly (e.g., 0.8–0.9) instead of going to ultra‑low.
• Heavy options to reduce
  • Turn shadows, special effects, motion blur, and extra post‑processing down to Low or Off.
  • These settings add a lot of GPU work but don’t help gameplay clarity much.

Guides show that 30 FPS + Medium/Low + reduced effects can cut heat drastically while keeping gameplay smooth.

Phone and System Tweaks

Small OS-level changes stack up over daily play.

• Close background apps and services
  • Shut down social apps, browsers, music streaming, GPS, etc. before launching Endfield to free CPU and RAM.
• Lower screen brightness
  • Displays are major power hogs; lower brightness noticeably reduces both heat and drain.​
• Use Wi‑Fi instead of mobile data
  • Wi‑Fi uses less power than 4G/5G radios during long sessions and runs cooler.
• Use Game Mode / performance profiles
  • Manufacturer “Game Booster” modes on Samsung, Xiaomi, etc. can limit background activity and smooth performance.​

Community reports of overheating on devices like Snapdragon 8 Gen 2 phones usually improve after these steps plus a 30 FPS cap.

Physical Thermal Management

How and where you play affects temperature as much as settings.

• Remove thick cases if the phone gets very hot
  • Rubber/silicone shells trap heat; taking them off improves passive cooling.
• Play in a cool, shaded environment
  • Avoid direct sun or hot surfaces; ambient heat accelerates throttling.
• Don’t game while charging
  • Charging and gaming together massively increase internal temperature and long‑term battery wear.
• Consider external cooling
  • Clip‑on fans or cooling pads help a lot for people who play long daily sessions.​

Official troubleshooting explicitly recommends cool environment, case off, and short breaks to keep devices healthy.

Good Habits for Long-Term Battery Health

Even with optimized settings, habits matter over months.

• Take short breaks every 30–60 minutes to let the phone cool.
• Avoid running at max brightness + 60 FPS + High graphics for hours; that’s the worst combo for battery aging.
• If your phone is near minimum spec and still struggles, use cross‑save to play heavier content on PC or console and keep mobile for dailies only.

Combining 30 FPS, Medium/Low graphics, reduced effects, closed background apps, and sensible cooling habits is enough to noticeably cut both heat and battery drain while keeping Arknights: Endfield smooth on most modern phones.
