Why does my game make phones overheat?

Because it drives the CPU and GPU hard for a sustained period, generating more heat than the phone can dissipate, often from an uncapped frame rate, heavy continuous work, or inefficient code. Phones generate heat in proportion to processor load and can only dissipate so much (small, passively cooled), so sustained heavy CPU/GPU load makes them overheat, leading to thermal throttling (the phone slows itself to cool down, hurting performance) and fast battery drain. The most common driver is an uncapped or excessive frame rate (rendering at maximum wastes power and heat), plus heavy per-frame work and not scaling down on weaker devices. Bugnet captures performance and device data from the field, so you can see whether your game sustains heavy load and on which devices, identify the workload driving the overheating, reduce it, and verify per version that the sustained load (and overheating) dropped, addressing the thermal problem at its source.

Does frame rate affect overheating?

Yes, a high or uncapped frame rate is a major cause of overheating, because rendering more frames means more GPU and CPU work, more power, and more heat, so capping the frame rate is often the most effective thermal fix. Each frame requires CPU and GPU work, so the more frames per second, the more total work the processors do, the more power they draw and heat they generate. An uncapped frame rate maxes the processors continuously, generating substantial heat (and draining battery). Capping at a sensible target (60fps, or 30 for some games) reduces the sustained load substantially, cooling the device, usually with minimal impact on the experience. Bugnet captures performance data from the field, so you can see your frame rate and sustained load on real devices, identify whether an uncapped frame rate is driving overheating, and verify per version that capping it (or other load reductions) lowered the sustained processor usage on the affected devices, confirming the thermal improvement.

How do I reduce heat and battery use in my game?

Reduce sustained CPU/GPU work, cap the frame rate, optimize hot paths, avoid unnecessary background work, and scale down on weaker devices, less sustained processor load means less heat and battery drain. Heat and battery drain both come from the processors working hard, so reducing them means reducing sustained load. Cap the frame rate (often the biggest win), optimize hot paths (so each frame costs less), avoid running heavy work continuously or when idle/backgrounded, reduce rendering cost, and scale down on weaker devices (which overheat faster). The optimizations that reduce heat also extend battery, since they are the same goal. Bugnet captures performance data from the field, so you can see where your game sustains heavy load (driving heat and battery drain) and on which devices, target those reductions, and verify per version that the sustained load dropped, confirming you reduced the processor work that causes both overheating and battery drain, improving both with the same optimizations.

Ways to Prevent Phone Overheating

Quick answer: Cap the frame rate, reduce the sustained CPU and GPU load, optimize hot code paths, and scale down on weaker devices, overheating comes from working the hardware too hard for too long.

A game that overheats phones gets hot, throttles, and drains battery, and players notice. Here are the best ways to prevent phone overheating.

Cap the Frame Rate

Prevent overheating by capping the frame rate, since an uncapped frame rate drives the GPU and CPU hard, generating heat. Capping at what the game needs cuts the sustained processor load and the heat it produces, often the biggest thermal win.

Bugnet captures performance data from real devices, so you can see your frame rate and sustained load and verify per version that capping the frame rate reduced the load that was overheating phones.

Reduce the Sustained CPU and GPU Load

Prevent overheating by reducing the sustained processor load, optimize hot paths, avoid running heavy work continuously, and reduce rendering cost, so the processors generate less heat. Less sustained work means less heat to dissipate.

Bugnet's captured performance data shows where the heavy sustained load is, so you can target the work driving the heat and verify per version that reducing it lowered the sustained load (and the overheating) on real devices.

Scale Down on Weaker Devices

Prevent overheating by scaling down on weaker devices, which overheat faster under load, give them lighter settings (lower quality, capped frame rate) so they do not work as hard. Scaling down keeps weaker devices within their thermal limits.

Bugnet captures performance and device data, so you can see which devices overheat (sustaining heavy load) and verify that scaling down for them reduced the sustained load that caused the overheating.

Prevent phone overheating by capping the frame rate, reducing the sustained CPU and GPU load, optimizing hot code paths, and scaling down on weaker devices. Overheating comes from working the hardware too hard for too long.
