To prevent thermal throttling and battery drain during high-bitrate Bilibili playback, select the HEVC (H.265) codec and lower Danmaku comment density. While AV1 delivers up to 30% bandwidth savings according to Dolby Optiview, mobile chipsets without dedicated AV1 silicon fall back to software decoding, which rapidly depletes the battery.

Recommended mobile playback configuration
Configure mobile playback to align hardware decoders with the player interface:
- Video Codec: Prioritize HEVC / H.265
Select HEVC in player settings. Chips from Apple and Qualcomm decode HEVC directly in silicon, avoiding the CPU-heavy software fallback required by AV1. - Resolution: 1080P / 1080P+
Streaming at 1080P+ requires an active account entitlement, such as a Bilibili Premium Membership (VN) for Vietnam-registered accounts. - Danmaku (Bullet Screen): Lower density or pause
High comment density forces continuous canvas redraws. Reduce the density slider or toggle comments off during fast action sequences. - Hardware Acceleration: Enabled by default, toggled on stutter
Leave hardware decoding active. If persistent buffering occurs on 1080P streams, Zhihu testing demonstrates that toggling hardware acceleration off can bypass browser-level decoding stalls.
Codec comparison: AV1 vs HEVC vs H.264
While higher compression saves bandwidth, complex algorithms require dedicated silicon to decode without draining power.
| Codec | Release / Finalized Year | Compression Profile | Mobile Hardware Status |
|---|---|---|---|
| H.264 (AVC) | 2003 | Baseline 16x16 macroblock encoding; lowest compression efficiency (Flussonic). | Universal hardware decoding support across virtually all legacy and modern devices. |
| HEVC (H.265) | 2013 | ~50% bitrate reduction versus H.264 (Flussonic). | Broad native decoding silicon across mobile chips from Apple and Qualcomm (Dolby Optiview). |
| AV1 | 2018 | ~30% higher compression efficiency compared to HEVC (Flussonic). | Higher computational complexity; software fallback decoders are slower and consume substantial battery (Dolby Optiview). |
HEVC provides the most reliable balance for mobile streaming. Unless a device specifically features dedicated AV1 silicon, selecting AV1 defaults to software decoders that consume battery fast.
Managing Danmaku overlay density
Rendering hundreds of real-time text vectors over a 60FPS anime stream spikes graphics load.
Lowering comment density or pausing the overlay removes visual clutter and reduces player overhead, as outlined in Immersive Translate's player guide. Setting Danmaku opacity to 50% or restricting text to the top half of the display keeps reactions readable without redrawing the entire screen surface every frame.
Offline caching for battery conservation
Streaming over cellular networks keeps mobile modems continuously powered, generating excess heat. To avoid this, Bilibili Premium Membership (VN) provides offline video caching for Vietnam accounts. Downloading 1080P episodes over Wi-Fi lets you shut off the cellular radio during playback, leaving only local hardware video decoding active.
