Reset Mechanics and Battery Charge
Battery Charge regenerates 1 per 6 minutes, reaching 240 cap in 24 hours. Daily coffee restores 60 Battery Charge, providing 300 total daily energy. Ether Battery items offer emergency 60 Battery Charge restoration.
Critical: Claim rewards via green progress bar before reset. Unclaimed rewards don't carry over.
Stamina Cost Breakdown
- Combat Simulator: 20-100 per attempt
- Routine Cleanup: 60 per run
- Expert Challenge: 40 per run
- Core Daily Errands: 0 Battery Charge
Combat Simulator Bounty Specialization delivers 22,500 Dennies per 20 Battery Charge—highest conversion rate. Spend all 300 Battery Charge daily to prevent overflow waste.
The 4-Minute Framework
Pre-Login Preparation (30 seconds)
Mental checklist:
- Current Battery Charge status
- Video store promoter from previous day
- Trust Event Agent locations
If under 3 minutes available, prioritize coffee and scratch cards only. Check HoYoLAB Daily Check-In (30 Polychrome) during loading screens.
High-Priority Tasks (2 minutes)
1. Coffee consumption (15 seconds)
Navigate to Coff Coffee immediately for 60 Battery Charge restoration.
2. Scratch cards (20 seconds) Visit newsstand—no decision-making required.
3. Combat Simulator (90 seconds)
Spend all 300 Battery Charge in HIA Club. Select Bounty Specialization matching material needs. With auto-battle, 15 runs at 20 energy each takes ~90 seconds with optimized teams.
Medium-Priority Tasks (1 minute)
4. Video store (25 seconds) Select 1 promoter + 3 movies. Minimal impact on reward variance—any selection works.
5. Trust Events (45 seconds)
Locate 3 yellow speech bubbles. Skip dialogue: 10-15 seconds per Agent.
6. Claim rewards (5 seconds) Click green progress bar in errands menu.
Optional Tasks (30 seconds)
Evaluate weekly mission progress. If 2+ minutes remain and Notorious Hunts incomplete, initiate one attempt (3-5 minutes per clear).

Stamina Management for Working Adults
Morning vs Evening Strategies
Morning clears (6:00-7:00 AM):
- Frontloads obligations
- Capitalizes on fresh mental energy
- Frees evening hours
Evening clears (9:00-11:00 PM):
- Accommodates variable schedules
- Allows workday Battery Charge regeneration
- Risks missed days if unexpected obligations arise
Split strategy: Morning coffee consumption + evening Combat Simulator runs maximizes regeneration efficiency.
Lunch Break Optimization
Pre-download assets and clear device cache before lunch. Prioritize Battery Charge expenditure; defer scratch cards and video store to evening.
Test network stability before Combat Simulator runs. Unstable connections waste Battery Charge without rewards. Use cellular data backup for unreliable workplace Wi-Fi.
Weekend Batch Processing
Allocate 30-45 minute blocks for:
- Notorious Hunts
- Hollow Zero Bounty Commissions
- Custom Schedule tasks (300 Inter-Knot Credit, 2 Ether Plating Agent, 7000 Denny weekly)
Weekend sessions enable experimental team compositions and strategic planning excluded from daily routines.
Priority Task Hierarchy
Tier 1: Never Skip
Coffee + scratch cards (30 seconds total) Guaranteed progression materials, contributes to 60 Polychrome daily reward.
HoYoLAB Daily Check-In (15 seconds) 30 Polychrome daily. Missed days = permanent loss.
Combat Simulator Battery Charge expenditure Prevents energy overflow. On busy days, run fastest-clearing stages regardless of rewards.
Tier 2: Character Progression
Video store management Passive Dennies overnight. Missing occasional days has minimal impact.
Trust Events Unlocks story content and minor stat bonuses. 3-interaction daily limit prevents catch-up.
Routine Cleanup + Expert Challenge Execute when specific resources become bottlenecks, not as habitual daily tasks.
Tier 3: Nice-to-Have
- Exploration activities
- City interaction bubbles
- Inventory organization
- Social features
Reserve for relaxed weekend sessions.
Emergency Routines
60-second window: Coffee only 90-second window: Coffee + scratch cards
Accept occasional incomplete days to prevent burnout. If next play window within 12 hours, Battery Charge skip acceptable—partial recovery through extended regeneration.
Combat Simulator Quick Clears
Stage Selection
Fastest clears: Bounty Specialization single-wave stages (25-35 seconds with optimized teams)
Avoid: Multi-wave stages add 10-20 seconds through spawn delays
Enemy composition matters: Clustered melee enemies enable AoE simultaneous elimination. Spread ranged enemies require sequential targeting.
Boss stages (40-100 Battery Charge, 2-4 minutes) belong in weekend sessions.
Auto-Battle vs Manual Control
Auto-battle:
- 15-30% slower than manual
- Enables hands-free farming
- Conservative AI prioritizes survival
Manual control:
- 20-30% faster completions
- Saves 3-5 minutes across 15 daily runs
- Requires dedicated attention
Hybrid: Auto-battle with manual intervention during critical moments.
Elemental Advantage
Matching Agent elements to enemy weaknesses amplifies damage 30-50%. Build three elemental-specialized teams (Fire, Ice, Electric) for optimal stage matching.
Vulnerability window exploitation: Chain ultimate abilities during weakness states for 10-15 second clears on optimal stages.
Budget approach: Prioritize one element for maximum investment using free Agents, gradually build secondary coverage.
Common Time-Wasting Mistakes
Over-Optimizing Low-Value Tasks
Video store: Any promoter + 3 movies delivers 95%+ maximum value in 10% analysis time
Scratch cards: Skip reveal animation, claim immediately (saves 10-15 seconds)
Trust Events: Skip dialogue without missing gameplay-relevant info (reduces 45+ seconds to 10 seconds per Agent)
Ignoring Stamina Overflow
Battery Charge at 240 cap wastes regeneration. Each hour = 10 lost energy. Set phone reminders for mid-day consumption.
Optimal coffee timing: 180/240 or lower, allowing restoration to stack with ongoing regeneration.
Reserve Ether Battery items for event farming, not normal daily routines.
Poor Menu Navigation
Use notebook icon (Z-marked) for instant errands access, not city exploration (saves 15-25 seconds)
Optimal routing: Complete all city errands (coffee, scratch cards, Trust Events) in single path before Combat Simulator
Batch-claim rewards via green progress bar after all four errands complete
Unnecessary Inventory Management
Don't review materials after each Combat Simulator run. Schedule weekly inventory reviews instead.
Immediately salvage/store equipment without examination. Comprehensive analysis belongs in weekend blocks.
Character menu browsing wastes time without enabling immediate decisions.
Advanced Time-Saving Tips
Mobile Performance Optimization
Enable performance mode in device settings—prioritizes processing power, maintains stable frame rates
Download all assets over Wi-Fi before mobile sessions (10-15 minutes initial, instant subsequent logins)
Disable screen recording/streaming during daily routines—consumes significant resources
Network Stability
Configure cellular data backup for automatic failover when Wi-Fi drops
Play within 15-20 feet of router during home sessions—reduces latency
Disable VPNs during gameplay—eliminates 1-3 second loading delays
PC Hotkey Configuration
Bind frequently used functions to accessible keys. Reduces input time 20-30% vs click-based interaction. 15-20 minute setup, permanent efficiency gains.
