您可能不知道，但Google Chrome、Firefox和YouTube正在耗尽您的Windows笔记本电脑的电池寿命。^{(battery life)}每当YouTube^(YouTube)开始卡顿时，或者当您的系统升温以及将风扇踢入新档时，您应该注意到这一点。

这主要发生在您使用Chrome或Firefox时，而使用Microsoft Edge和Internet Explorer时则较少。Firefox和Chrome的这个问题在Mac^(Macs)上可能更严重，但我们今天不打算深入研究。

为什么在Firefox或Chrome上观看^(Chrome)YouTube视频会消耗电池电量

口吃和电池性能问题都有一个敌人，那就是YouTube 切换到 HTML5^{(YouTube’s switch to HTML5)}来播放视频。Google正在缓慢但肯定地摆脱YouTube的Flash，但这样做，它也摆脱了被视为行业标准的H.264 媒体编解码器。^{(H.264 media codec)}

Google和Mozilla都不想支持H.264，因为它背后有很多专利。要使用它，这些公司必须向专利持有人付款，他们希望阻止这种情况发生。

Firefox长期以来不支持H,264，但今年迫于压力不得不低头。

为了结束H.264的主导地位，谷歌^(Google)在 2011 年收购了一种名为VP8的新媒体编解码器。任何人都可以免费使用，但尽管如此，编解码器未能获得很大的吸引力，尽管Firefox目前是其支持者。

VP8的失败并没有贬低谷歌^(Google)，因为该公司选择创建VP9并承诺将终止对H.264的支持，但到目前为止，这一切都是空谈，因为到目前为止，Chrome仍然支持编解码器。

此外，在YouTube 上^(YouTube)播放视频时，Chrome和Firefox都会切换到VP9并让H.264死机。

女士们，先生们，这一切都归结为硬件加速。使用GPU来卸载大部分工作可以提高计算机性能。问题是; 硬件加速仅受H.264支持，而VP9很大程度上依赖于CPU为其提供所需的提升。

AMD和NVidia等许多公司都承诺支持VP9，但 5 年后，还没有发生任何事情。

这使计算机用户可以涉足他们的选择。他们可以简单地切换到Microsoft Edge和Internet Explorer，因为这些浏览器不支持VP9，因此，由于硬件加速， YouTube和大多数其他网站上的视频播放应该是无痛的。^(YouTube)但是，切换到这些浏览器可能是一个艰难的问题。

使用 h264ify 插件

下一个选项是为Chrome和Firefox下载一个名为h264ify的插件。此插件强制Firefox和Chrome从YouTube请求H.264。走这条路应该可以解决电池寿命问题，但我们不能确定 h264ify 将被支持多长时间

如果我们是你，我们会选择 h264ify。它有效，我们几乎立即看到了视频性能的差异。

Stop Chrome and Firefox from draining your laptop battery

You might not know it, but Google Chrome, Firefox, and YouTube are draining the battery life of your Windows laptop. You should notice this whenever YouTube begins to stutter, or when your system heats up along with kicking the fan into a new gear.

This happens mainly when you’re using Chrome or Firefox, and less so with Microsoft Edge and Internet Explorer. This issue with Firefox and Chrome is probably even more of a problem on Macs, but we’re not going to dig into that today.

Why viewing YouTube videos on Firefox or Chrome drains battery

The stuttering and the battery performance issues, all have a single enemy, and that is YouTube’s switch to HTML5 for video playback. Slowly but surely Google is ridding YouTube of Flash, but by doing so, it is also getting rid of the H.264 media codec that is seen as the industry standard.

Neither Google or Mozilla wants to support H.264 because it has a lot of patents behind it. To use it, these companies must pay the patent holders, and they wish to stop this from happening.

Firefox for a long time did not support H,264, but had to bow under pressure this year.

To end the dominance of H.264, Google acquired a new media codec called, VP8 back in 2011. It is free for anyone to use, but despite that, the codec failed to gain much traction, although Firefox is currently a supporter.

Failure of VP8 did not detract Google, as the company chose to create VP9 with the promise that it would end support for H.264, but so far, it was all talk because up to this point, Chrome still supports the codec.

Also, when playing videos on YouTube, both Chrome and Firefox switches to the VP9 and leaves H.264 for dead.

It all boils down to hardware acceleration, ladies and gentlemen. Using the GPU to offload the majority of the work makes for smoother computer performance. The problem is; hardware acceleration is only supported by H.264 while VP9 relies a lot on the CPU to give it the boost it needs.

Many companies such as AMD and NVidia have promised to support VP9 where this is concerned, but after 5-years, nothing has happened yet.

This leaves computer users to dabble through their options. They can simply switch to Microsoft Edge and Internet Explorer because those browsers do not support VP9, and as such, video playback on YouTube and most other websites should be painless due to hardware acceleration. However, switching to those browsers might be a tough ask.

Use h264ify plugin

The next option is to download a plugin for both Chrome and Firefox that is called, h264ify. This plugin forces Firefox and Chrome to request H.264 from YouTube. Going this route should fix battery life issues among others, but we can’t be sure for sure how long h264ify will be supported

If we were you, we’d go with h264ify. It works, and we saw a difference in video performance almost instantly.
