Genshin Burst Uptime Calculator

Calculate your Elemental Burst uptime and Energy Recharge (ER) requirements. Determine if your character can burst on every rotation and find the optimal balance between ER and damage stats.

Interpreting Your Result

Excellent (A): Burst is ready 2-3 seconds before CD ends; 100% uptime on buffs. Good (B): Burst is ready exactly on CD. Marginal (C): Need to swap and use extra skills to finish charging (DPS loss). Poor (D): Burst takes 5+ seconds after CD to charge; total rotation fail.

✓ Do's

  • Prioritize meeting your ER threshold before maximizing CRIT stats — a burst that isn't cast deals zero damage.
  • Use a "Battery" character of the same element (e.g., Bennett for Xiangling) to double particle efficiency.
  • Catch particles on the character who needs energy most (Energy Funneling).
  • Consider Favonius weapons for supports to lower the entire team's ER requirements.
  • Account for enemy HP-threshold particles; bosses provide much less energy than groups of mobs.

✗ Don'ts

  • Don't overstack ER beyond your needs; every % past 100% uptime is a wasted stat that could have been ATK or CRIT.
  • Don't assume 100% ER is enough for off-field characters — they almost always need 180%+.
  • Don't ignore the "Flat Energy" gains from weapons like Amenoma Kageuchi or characters like Venti.
  • Don't forget about "Hitlag" — melee hits can slightly extend the duration of some bursts (like Raiden or Itto).
  • Don't use 4-star ER sands if you can achieve the same ER through substats and use an ATK/EM sands instead.

How It Works

The Genshin Burst Uptime Calculator is a precision tool for optimizing character energy cycles. In Genshin Impact, "uptime" refers to two things: the percentage of time a Burst effect is active, and the ability to cast that Burst immediately when its cooldown ends. This calculator helps you determine exactly how much Energy Recharge (ER) you need based on particle generation, enemy drops, and team batteries. Stop over-investing in ER at the cost of CRIT, and start building exactly what your rotation requires.

Formula Used

Energy Gained = (Particles × Particle Value × ER%) + (Flat Energy Gains) Particle Values: Same Element (3), Different Element (1), Neutral (2) Off-field Multiplier: ~0.6x Uptime % = (Burst Duration / Max(Burst Cooldown, Rotation Length)) × 100

Real Calculation Examples

  • 1Bennett (Cost 60, 15s CD): With 200% ER and 3 Pyro particles caught on-field, he gains (3 × 3 × 2.0) = 18 energy per skill. To burst on CD in a 15s rotation, he needs ~42 more energy from the team.
  • 2Xiangling (Cost 80, 20s CD): Often needs 220%+ ER because she catches particles off-field (0.6x multiplier). 80 / (Particle Gain × 0.6 × 2.2) = Rotation viability.
  • 3Raiden Shogun (Cost 90, 18s CD): Her massive flat energy restoration reduces the ER% needed by other teammates by roughly 20-30%.

The Comprehensive Guide

Genshin Burst Uptime Calculator: The Ultimate Mastery Guide

In the world of Genshin Impact, damage is king, but Energy is the kingdom. You can have the highest critical damage in the world, but if your character is standing still waiting for their Elemental Burst to charge, your DPS (Damage Per Second) is zero. This Genshin Burst Uptime Calculator and accompanying guide provide the mathematical blueprint for perfect rotations, ensuring your team flows like water through every Abyss floor.

Understanding the Two Pillars of Burst Uptime

In the community, "Burst Uptime" is often used to describe two distinct concepts. To truly master the game, you must understand both:

  1. Theoretical Uptime: The duration of the burst divided by its cooldown. For example, Zhongli’s shield (Burst/Skill) lasts 20 seconds with a 12-second cooldown, yielding >100% theoretical uptime.
  2. Practical Cycle Uptime: The ability to re-cast a Burst exactly when its cooldown ends. This is entirely dependent on your Energy Recharge (ER) and your team's particle generation.

Our calculator focuses on Practical Cycle Uptime—the mechanical heartbeat of any high-end Genshin team.

The Energy Recharge Formula: How Much is Enough?

The biggest mistake players make is over-investing in damage stats while ignoring ER. A "failed rotation"—where you have to spend 5-10 extra seconds generating energy for a character—is the single greatest DPS loss in the game. Generally, a 5-second delay in a 20-second rotation is a 25% flat damage reduction for your entire team.

Standard ER Benchmarks by Role

Character Role Typical ER Needs Why?
On-field Main DPS 120% - 140% They catch their own particles on-field (100% value).
Off-field Sub-DPS 180% - 240% They catch particles off-field (~60% penalty).
Burst Support (Utility) 200% - 260% Often only on field for 1s to cast Burst.
Raiden/Venti Teams Reduce by 30-50% Flat energy regeneration bypasses ER requirements.

Elemental Particles vs. Elemental Orbs

Not all "energy" is created equal. There are two types of drops: Particles (small) and Orbs (large, roughly 3x the value of a particle). Additionally, the Color of the energy matters. Using our Genshin Energy Calculator, you should account for these values:

  • Matching Element: 3 Energy per particle on-field.
  • Neutral (White) Energy: 2 Energy per particle on-field.
  • Different Element: 1 Energy per particle on-field.

*Note: Off-field characters receive roughly 60% of these values.

The "Battery" Secret: Maximizing Funneling

Energy Funneling is the pro-player technique of using an Elemental Skill with a support (like Bennett) and switching to the carry (like Xiangling) before the particles reach the character. This ensures the carry Gets the "Matching Element" + "On-field" bonus (3 energy per particle), which is the most efficient way to charge high-cost bursts.

How HP-Threshold Drops Affect Your Abyss Runs

Have you ever noticed your bursts charge faster against groups of Hillichurls than against a single Boss? This is due to HP-threshold particles. Most enemies drop neutral energy at 60% and 30% HP, and elemental energy at 0% (death). Against a Boss with 2 million HP, you might only get 2 threshold drops. Our calculator allows you to factor in "Enemy Density" to ensure your Abyss build works in both AoE and Single Target scenarios.

Breaking the Stats: Is 300% ER Worth it?

While Energy Recharge is vital, there is a point of diminishing returns. Characters like Raiden Shogun or Mona have passives that convert ER into damage (Elemental DMG Bonus). For them, high ER is a dual-benefit. However, for a character like Xiangling, every % of ER past your "Burst-on-CD" target is a wasted roll that could have been Crit Rate or Attack.

Pro Tip: Use our calculator to find your "Minimum Viable ER," then dump everything else into Offensive stats.

The Role of Weapons: Favonius vs. Sacrificial

Two weapon series are the MVP of Burst Uptime:

  • Favonius Series: Generates 3 Neutral particles on Crit. Provides ~6 energy to the whole team. Best for high-hit-count supports.
  • Sacrificial Series: Resets Elemental Skill CD. Allows you to generate 2 sets of particles back-to-back. Best for characters with high-cooldown skills like Xingqiu or Diona.

The "Flat Energy" Bypass

Flat Energy restoration is a mechanic that restores energy directly, ignoring the Energy Recharge stat. This is common in "Amenoma Kageuchi" sword, Venti's burst, or Raiden's burst. Because this energy is static, it is more valuable for characters with lower ER builds. For example, Venti restoring 15 energy to an 80-cost burst reduces the "Effective Cost" to 65.

Theoretical vs. Practical Energy Recharge (ER)

Theoretical energy is what you see in the character menu. Practical energy is what actually lands in your character's bar during the chaos of a 12-3 Abyss chamber. Many players reach the "theoretical" threshold but fail in practice because they miss a funnel or an enemy moves out of range. To solve this, always aim for a 15-20% ER overhead beyond the absolute minimum shown in theorycrafting sheets.

Table B: Energy Particle values by Scenario

Source On-Field (Same) On-Field (Diff) Off-Field (Same) Off-Field (Diff)
Elemental Particle 3.0 1.0 1.8 0.6
Elemental Orb 9.0 3.0 5.4 1.8

The Impact of Constellations on Uptime

Constellations can drastically change your energy economy. For example, Xingqiu C6 restores 3 energy every third sword wave, effectively lowering his burst cost from 80 to roughly 65. Similarly, Faruzan C6 generates pressurized collapses that drop particles off-field, solving her notorious energy issues. When using the Genshin Burst Calculator, ensure you factor in these specific constellation bonuses to avoid over-stacking ER.

Optimal ER Benchmarks for Meta Teams

  • Rational (Raiden National): Raiden (~250%), Xiangling (~180-200%), Xingqiu (~170%), Bennett (~160%). Raiden acts as the universal battery.
  • International (Childe): Xiangling (~230%), Kazuha (~160%), Bennett (~190-210%). No Raiden means much higher needs for Xiangling.
  • Hyperbloom (Nahida): Nahida (~130%), Kuki (~120%), Yelan (~180-200%). Yelan is the main energy bottleneck here.

Strategic Energy Collection: The "Orb Buffer"

In Wave-based content, don't waste your ultimate on the final 5% HP of an enemy. Save it for the start of the next wave. This allows the particles from the dying wave to fill your bar for the next chamber, ensuring you start with a "Full Tank." This is a key technique for achieving fast clear times in the Spiral Abyss.

Why Defense-Oriented Energy Matters

Getting interrupted (staggered) during your energy-generating skill (like Bennett's Tap E) means you lose those particles and the 2-4 seconds it takes to attempt the skill again. This is why Interrupt Resistance (Zhongli shield, Raiden burst state) is indirectly an energy-generation stat—it guarantees your particles are generated on time, every time.

Conclusion: Mastery Through Math

Don't be a traveler who relies on luck for their burst. In the high-stakes environment of the Spiral Abyss, consistency is the difference between a 3-star clear and a frustrating retry. Use the Genshin Burst Uptime Calculator to audit your builds, balance your Energy Recharge, and ensure that every time you call upon the elements, Teyvat answers.

Frequently Asked Questions

Usage of This Calculator

Who Should Use This?

Combat enthusiasts optimizing Spiral Abyss clears, theorycrafters determining the "Value" of ER vs DMG stats, players building new teams who want to avoid "dead rotations," and F2P players trying to make the most of limited artifact rolls.

Limitations

The calculator assumes average particle generation luck. Actual energy gain can vary slightly based on enemy behavior, exact HP-drop timings, and specific "particle RNG" mechanics of certain skills.

Real-World Examples

Xiangling in Rational Team

Scenario: Energy cost 80. Team: Raiden, Xingqiu, Bennett. Xiangling stays off-field.

Outcome: Raiden restores ~25 energy. Bennett skill generates 3 Pyro particles. Xiangling needs ~220% ER to consistently burst because of the off-field 0.6x multiplier.

Ayaka Freeze Rotation

Scenario: Ayaka cost 80. Diona as battery. Ayaka catches Diona particles on-field.

Outcome: Diona generates 4 particles (12 energy). Ayaka catches them (100% value). With 140% ER and Amenoma Kageuchi (R5), Ayaka can burst comfortably every 20s.

Summary

The Genshin Burst Uptime Calculator is the definitive guide to energy management in Teyvat. By balancing your Burst cost against particle generation and ER%, you can ensure 100% combat efficiency and never waste a second of your rotation again.
