Auto is the only frame-rate choice designed to react to device temperature: it starts at 30 FPS, can switch to 60 FPS after the phone stays cool and stable, and returns to 30 FPS when elevated temperature persists. Fixed 30 FPS and 60 FPS do not make that adjustment.
These settings can reduce load, but Devsisters has published no FPS, temperature, battery, or reload-rate benchmarks. The recommendations below therefore explain the intended behavior of each option and give a safe way to compare settings on your own phone.

Start with the setting that matches the problem
There is no single “best” configuration for every phone. Choose the first change according to the symptom you see:
- Heat or frame-rate swings: select Auto first. If the phone stays hot or frame pacing remains uncomfortable, compare it with fixed 30 FPS.
- A phone that stays cool and has performance headroom: try 60 FPS, but remember that it remains fixed and will not lower itself when the device overheats.
- Kingdom-view stutter, long pauses, or a lower-memory phone: leave Simple Buildings on. It replaces some animated building scenes with static images to reduce memory use.
- Load associated with Cookies: use the Cookie Activity and Cookie Animation options if they are present in your installed version.
- Persistent overheating: experiment with the available Resolution choices. The July 29, 2026 update says the option was optimized to reduce overheating, but it does not prescribe one level for every device.
Change one setting at a time, play the same type of content for several minutes, and note temperature, hitching, and reloads. That gives you a more useful comparison than changing every option simultaneously.

How the 30 FPS, Auto, and 60 FPS choices differ
The August 12, 2026 update added three named choices: 30 FPS, Auto, and 60 FPS. Their key difference is whether the game is allowed to change the frame rate in response to temperature.
| Choice | Behavior described by Devsisters | When it makes sense | Heat caveat |
|---|---|---|---|
| 30 FPS | Fixed 30-frame-per-second cap. | Use when you prefer a predictable lower cap or Auto still leaves the phone hot. | It does not automatically react to temperature, although the lower cap may be a practical heat-reduction experiment. |
| Auto | Starts at 30 FPS, switches to 60 FPS after the device temperature remains stable for a certain duration, and returns to 30 FPS if temperature remains elevated at 60 FPS for a certain duration. | Best first test for mixed play sessions and phones that heat up unpredictably. | It is the only listed choice with temperature-responsive behavior. |
| 60 FPS | Fixed 60-frame-per-second cap. | Try it on a phone that can sustain higher frame rates without excessive heat or stutter. | It will not lower itself when the device gets hot; switch to Auto or 30 FPS yourself if heat builds. |
Devsisters’ notice does not state how long “a certain duration” is, what temperature threshold triggers a change, or how quickly the transition occurs. Do not treat Auto as a guaranteed 60 FPS mode: it may remain at 30 FPS whenever the phone has not reached the stated stability condition.
A practical frame-rate test
- Close other demanding apps, let the phone return to a normal temperature, and launch CookieRun: Kingdom.
- Play a repeatable activity such as moving around the Kingdom, opening menus, and entering a battle. Avoid comparing a quiet menu with a crowded battle.
- Use Auto for the first session. Observe whether the phone becomes warm, whether motion feels consistent, and whether the frame rate changes after sustained play.
- If heat or inconsistent pacing remains a problem, repeat the same activity at fixed 30 FPS.
- If both sessions stay cool and you want a higher cap, test 60 FPS. Stop the test if the phone becomes uncomfortably hot or performance degrades.
This is a comparison method, not a promise of a particular FPS result. Official materials provide no benchmark showing how much smoother, cooler, or more battery-efficient any choice will be on a specific model.
Why Auto is the best first choice for heat
Auto is designed around a simple feedback loop. The game starts conservatively at 30 FPS. If the device temperature remains stable for a period, it can move to 60 FPS. If the phone is running at 60 FPS and its temperature remains elevated for a period, the game drops back to 30 FPS. That behavior is intended to balance responsiveness with thermal conditions.
Fixed choices do not perform that automatic adjustment. Selecting 60 FPS means accepting responsibility for switching away from it when the phone cannot stay cool. Selecting 30 FPS gives a fixed cap, which some players may prefer for consistent behavior even though the setting itself is not temperature-aware.
Because the notice does not publish thresholds or measured gains, judge Auto by your own symptoms: sustained heat, obvious hitching, touch-response consistency, and whether the game becomes less comfortable after a long session. A short launch test cannot show the full temperature behavior.

Simple Buildings: trade animated detail for memory headroom
Simple Buildings addresses memory pressure rather than frame-rate selection. Devsisters describes it this way: “This option displays the animations of some Kingdom buildings as static images to reduce memory usage for smoother gameplay.” The change affects presentation in the Kingdom. It is not described as a reduction to battle mechanics.
The July 29, 2026 notice says Simple Buildings is enabled by default on:
- iOS devices with 4 GB RAM or less.
- Android devices with 3 GB RAM or less.
Players can change the option in Settings. The available notice does not show a complete menu path or enumerate every building affected, so the label and exact location may vary with the installed version. If the option is present, leave it enabled on a lower-memory phone or when the Kingdom view pauses, reloads, or becomes sluggish. Disable it only if animated buildings matter more to you than the additional memory headroom and the phone remains stable.
What Simple Buildings can and cannot solve
- Likely target: memory use from animated Kingdom buildings and the resulting pauses or reload pressure.
- Not established: a guaranteed battle-FPS increase, a specific amount of RAM saved, or a particular temperature reduction.
- Visual trade-off: some building animations become static images, so the Kingdom may look less lively.
- Battle scope: the description concerns Kingdom building presentation; it does not say that Cookie combat animations are removed.
Cookie Activity and Cookie Animation options
The August 26, 2026 notice added Cookie Activity and Cookie Animation options to reduce the performance load caused by Cookies. These controls are aimed at lower-end devices or sessions where Cookie activity and animation are contributing to strain.
The notice does not provide the exact toggle values, a complete menu path, a list of which animations are affected, or a measured improvement. If the options appear in your installed version, use them as controlled experiments:
- Open the game’s Settings and look for the Cookie Activity and Cookie Animation labels.
- Change one option, then return to the same Kingdom area or activity that normally stutters.
- Compare memory pressure, hitching, and reload behavior over a similar play period.
- Keep the less demanding choice if it improves stability; restore the original choice if the visual change is unacceptable and the phone remains reliable.
Do not assume that a particular value is universally best when the official notice does not define the values or quantify their effect. The purpose is clear—reducing Cookie-related load—but the amount of relief depends on the device and the activity.

Resolution and overheating
The July 29, 2026 update says the Resolution option was optimized to reduce device overheating. It does not publish a numeric recommendation, a target resolution, or a test result. That means there is no official “set Resolution to X” rule that applies to every phone.
If your version offers multiple levels, a lower available level is a reasonable troubleshooting experiment, not a Devsisters-prescribed setting. Check text and interface clarity after changing it, then compare the same activity for heat and stutter. Keep the lower level only if the visual compromise is acceptable and the phone behaves better. If clarity is poor or there is no practical improvement, return to the previous level.
Resolution interacts with frame rate: a phone may handle a lower image load more comfortably, but the official notice does not establish a guaranteed FPS or temperature change. Record what happens on your device instead of attaching a percentage to the adjustment.

Profile: the phone becomes hot during a long session
- Set Frame Rate to Auto.
- Keep Simple Buildings enabled if available.
- Use Cookie Activity and Cookie Animation controls to reduce Cookie-related load when offered.
- Try a lower available Resolution level as an experiment, checking readability.
- If the phone still heats up, use fixed 30 FPS and stop the session when the device becomes uncomfortably hot.
Auto can return to 30 FPS after sustained elevated temperature, but fixed 60 FPS will not do that automatically.
Profile: low frame rate or hitching in the Kingdom
- Keep Simple Buildings on to reduce memory use from animated buildings.
- Use Auto and observe whether the phone remains stable long enough to switch to 60 FPS.
- If the phone cannot sustain that behavior, compare fixed 30 FPS.
- Reduce Cookie-related activity or animation if those options are available.
- Test Resolution only after the memory-focused options, so you know which change helped.
Profile: the Kingdom reloads or closes on a lower-memory phone
- Confirm Simple Buildings is enabled.
- Close other apps and free device storage and memory before launching the game.
- Use the Cookie Activity and Cookie Animation controls if present.
- Prefer Auto or 30 FPS over fixed 60 FPS while diagnosing heat and memory pressure.
- Check the support minimums and update the operating system.
Devsisters specifically notes that the Kingdom may reload on low-end iOS devices when available memory runs low. A reload is therefore a memory warning sign, not proof that a frame-rate setting alone is defective.
Profile: the phone is cool and you want the highest cap
- Try 60 FPS only after confirming that the device remains cool and stable during your normal activities.
- Watch for heat or frame pacing that worsens over time, not just during the first minute.
- Switch to Auto if you want the game to respond to temperature without manual intervention.
60 FPS is a higher fixed cap, not a guarantee of smoother play on hardware that cannot sustain it. A fluctuating or overheating 60-FPS session can feel worse than a stable 30-FPS session.

Device and installation checks before changing graphics
Settings cannot compensate for an unstable connection, an outdated operating system, insufficient memory, or an unsupported installation. CookieRun: Kingdom support lists these minimums and checks:
| Platform | Support minimum listed | Important qualification |
|---|---|---|
| iOS | iOS 13 or newer; at least 2 GB RAM. | Meeting the minimum does not guarantee smooth gameplay. |
| Android | At least 3 GB RAM. | Meeting the minimum does not guarantee smooth gameplay. |
The support guidance also recommends a stable network, installing the official app-store version, keeping the OS up to date, and freeing device memory. Additional storage may be needed for installation and updates. These are prerequisites and troubleshooting checks, not performance guarantees.
Use this order when problems persist
- Connection: test on a stable network. Network delay can look like game lag even when rendering is normal.
- Installation: confirm the app came from the official app store and is fully updated.
- Operating system: install the current OS update supported by your phone.
- Memory and storage: close background apps and free space before launching the game.
- Requirements: compare the phone with the listed iOS or Android minimums.
- In-game settings: then test Auto, Simple Buildings, Cookie controls, Resolution, and fixed 30 FPS one at a time.
If the phone meets the minimum but still reloads or overheats, that does not contradict the support page: minimum specifications define a baseline for installation and operation, not a promise of smooth performance in every Kingdom or battle.
What about Apple Game Mode?
Apple says Game Mode on supported devices and games can prioritize performance for smoother, more consistent frame rates and improved responsiveness. Apple’s article specifies an iPhone running iOS 18 or later and a supported game. The available information does not confirm that CookieRun: Kingdom is supported by Game Mode.
If Game Mode appears for the game on your compatible iPhone, you can follow Apple’s on-screen behavior and compare a repeatable activity with it enabled and disabled. If the option does not appear, do not assume it is available or that another setting can force it on. Treat Game Mode as a conditional platform feature, separate from CookieRun: Kingdom’s own frame-rate and graphics controls.

Common mistakes and safer fixes
Expecting 60 FPS to be automatically smoother
A 60-FPS cap can be beneficial on hardware that sustains it, but fixed 60 FPS does not temperature-adjust. If heat causes inconsistent rendering, Auto or fixed 30 FPS may provide a steadier experience.

Turning off Simple Buildings on a low-memory phone
Animated buildings use more memory than the static-image presentation described by Devsisters. On a phone at or below the default-enable thresholds, disabling the option can work against the reason it was enabled. Test it only if you accept the risk of more memory pressure.
Looking for an official resolution number
The update says Resolution was optimized for overheating, but it gives no universal level. Choose among the levels your version actually shows and evaluate clarity and heat on your own device.
Changing every option at once
When frame rate, Resolution, building presentation, and Cookie controls all change together, you cannot identify the cause of improvement or deterioration. Use one change per test session.

A stable connection is part of official support guidance. If inputs, loading, or online actions are delayed while animation remains fluid, investigate the network before lowering graphics settings.
Trusting a short cold-start test
Auto’s behavior depends on temperature remaining stable or elevated for a period. A one-minute test may end before the phone reaches the condition that causes a switch. Compare sessions long enough to represent your normal play, while stopping if the device becomes uncomfortably hot.
A repeatable checklist for your phone
- Record the phone model, operating-system version, and whether the problem is heat, hitching, reloads, or connection delay.
- Confirm the game is current and installed from the official store.
- Close background apps and free memory and storage.
- Set Frame Rate to Auto and test a repeatable Kingdom or battle activity.
- Keep Simple Buildings enabled on lower-memory devices or when Kingdom reloads occur.
- Try Cookie Activity and Cookie Animation controls if available.
- Experiment with Resolution only as a device-specific test; inspect visual clarity.
- Compare fixed 30 FPS if Auto remains hot or inconsistent.
- Try fixed 60 FPS only when the phone can remain cool and stable.
- Write down the result of each single change instead of relying on memory.
No official notice supplies a percentage improvement for these settings. The useful outcome is a configuration that keeps your particular phone responsive and comfortable during the activities you actually play.
