What's the difference between power saving and Support Mode?

Which switch does what
QuestionSwitchWhat to check
Device stays on and I want it to run cooler Power-saving mode Connection stays up; the app stays in the foreground
What does my character do while I'm gone? Support Mode Activity order, stop on death, weight limit, whether auto-maintenance is available

They're separate switches, and turning on one doesn't set the other. If you only turn on Support Mode, the game keeps running at normal load, which is fine for a short break but not ideal overnight.

Short answer

Use both. Power-saving mode in VAMPIR only lowers the screen load while the app stays open; Support Mode decides what your character does while you're away and when it stops. A checklist before you go AFK and what to check when you come back to nothing.

What should you set before going AFK?

  1. Watch the character for a minute in the spot you picked. If HP keeps dipping, change the spot before you change the mode.
  2. Set the queue: daily content first, farm last. Turn on stop-on-death.
  3. Check potions, bag space and the weight limit. If you own Olga's Grace, enable auto-maintenance and check the dismantle rules it'll use.
  4. Turn on power-saving mode and note the time, your level and your gold.
  5. When you're back, judge by those numbers, not by whether the screen is still on.
Diamond farming starts at 0:40, the summon safety net at 2:15.

I came back and nothing happened. Why?

Check in this order: was the app still in the foreground and connected; did the queue stop on death or weight; did the bag fill; did the potions run out. Since Netmarble's September 16 update, auto-battle also switches itself off if your character hasn't fought anything for five minutes after you turn it on. Change one setting at a time and watch for a few minutes before you leave again.

FAQ

Does power-saving mode stop auto-battle?
No. It only changes the screen load. Your character keeps doing whatever it was doing, just without a queue or a stop rule unless Support Mode is on.
Can VAMPIR keep farming with the app closed?
Support Mode can hand off to an offline mode: Netmarble's September 16 update fixed a bug where dungeon plan time restarted when you switched from Support Mode to offline mode. The Korean guide doesn't explain offline mode in detail yet.
Where are the two switches?
Both sit in the second area of the main screen, next to chat.
