The battle of the week: Mixer vs Twitch

Reading Time: 3 minutes

A few weeks ago, the famous American streamer under the pseudonym of Ninja announced that he left the streaming platform Twitch for its competitor: Mixer. In just a few days, the milestone of one million paid subscribers had been reached and the platform was the top spot for the most downloaded free apps in the United States. Today’s match is between these two competing applications: Mixer vs. Twitch.

In the left corner Mixer, (formerly Beam) the video game streaming service launched by Microsoft in January 2016.

In the right corner Twitch, leading platform for streaming video games (and other broadcasts) launched in June 2011. It has more than 35 million unique visitors per month.

The weighting

At weighing Mixer is the heavier application with a weight of 114 MB. Its opponent Twitch is lighter with a weight of 95 MB, or 16% less .

The fight

All the lights are now turned on the fighters and the match can finally begin.

In the first part of the battle to measure the impact of the launch phase of the application, Twitch assom Mixer in consumption more than 3x less energy. The difference in consumption is quite marked also on the streaming phase. Indeed, Twitch (11.6 mAh) dishes Mixer (15.4 mAh) K.O with a lower consumption of 24%. To end this confrontation, we have set up two decisive rounds of observation of the rest phases of each opponent. During the foreground phase, Twitch is still the master of the game, consuming 60% less. For the inactivity phase in the background it is a perfect draw!

The bell rings, end of the match!

The winner

Without any surprise, it’s a knockout victory for the Twitch app, declared victorious against its opponent Mixer on an overall score of 15.3 mAh at 23.9 mAh, either by consuming overall 56% less energy. Note that the Twitch power consumption is still very high. Twitch also dominates its competitor Mixer on memory consumption (-45%) and storage space. Mixer is doing well on data exchanged (-9%).

Energy consumption of the 30 most popular mobile apps in the world

Reading Time: 3 minutes

All our digital uses have an impact of energy consumption and in a more global way in technical resources (RAM, CPU, Data, …). The environmental impact of digital is today important and especially in strong progression. Today, according to the project shift * report, the impact of digital in terms of greenhouse gas represents 3.7% of total emissions (GHG) on the planet and could represent, according to the assumptions, between 7 and 8.5% in 2025, the equivalent of the GHG emissions of light vehicles on the planet (8% of GHG). This is reinforced by an annual growth of 8% which remains and will remain sustained despite technological progress.

Access to information, content and services is now predominantly done on smartphones, which has become the flagship of digital activity. We connect more and more, from everywhere, and at any time.
Today, the consumption of smartphones (including the use phase and the manufacturing phase) represents 11% of the digital energy consumption. Sensitive point of this energy consumption for the smartphone that is at the battery and is the focus of all our attention and those of smartphone manufacturers. We often accuse our smartphones of lack and / or loss of autonomy … Yet it is the applications installed on the smartphone that consume! … and which also degrade its battery capacity over time. Mobile applications are now used, for the most deployed, by billions of people (more than 5 billion mobile users). Today, an application like Facebook, the most popular, is used by more than 2 billion active users per month on smartphone. The impact of these applications is therefore considerable and a significant improvement in the sobriety of one of them can have rapidly very positive consequences on the ecological impacts.

As part of the Vivatech 2019, with our partner ATOS, we wanted to raise the awareness of major digital players by benchmarking the consumption of resources and energy of the 30 most popular applications.

5 key points of this study

  • The pre-loading of the time line data is consumption factor. The fact that this content is video type like TikTok makes it a consumer application for the device but even more so on the network and the datacenter. An ecological heresy when you know that this application is used by millions of people around the world..
  • Web browsing consumes a lot of energy because the pages include many scripts, more and more (trackers, advertisements, differentiating features, …) that are not well managed by the hardware of the smartphone. Calling consumes half the average on average than surfing.
  • In each category of applications large discrepancies exist for near functionalities which can translate avoidable mess and thus gains of accessible optimizations. 30-40%?
  • Yes, listening to music on Youtube is an ecological “mistake” when you know the consumption of a Spotify. Features “listening music without image” favored on video players are expected.
  • The global electricity consumption of digital is at the scale of a continent (Russia + Japan combined), that of the use of applications on smartphones is that of a European country (equivalent to Ireland). 1/3 of gain conceivable when positioning the average of the category on the lowest consumption of the category (equivalent functionality). On a global scale, a nuclear slice avoided. For our smartphones, 2 to 3 hours of autonomy and more!

The battle of the week: Amazon Prime Video vs Netflix

Reading Time: 2 minutes

Today’s match will oppose two applications of the video services on demand category. Indeed, the fighters are Amazon Prime Video and Netflix.

In the left corner Amazon Prime Video, created in 2006, is the video service on demand created by the giant Amazon, Netflix’s first competitor on the market.

In the right corner Netflix, created in 1997, is today the most used application to watch a serie or a movie on a smarthpone.

The weighing

At the weighing Amazon Prime Video is the heaviest application with 107 Mb. It’s opponent Netflix is clearly lighter with 77 Mb.

The fight

All the lights are now turned on the fighters and the match can finally begin.

The start of the match is pretty tight but Amazon Prime Video take a small advantage, consuming 0.8% less battery. The fight goes on, with the movie watching scenario during a minute, and this time Netflix reacts and overturn the situation consuming 4.3% less than Amazon Prime Video. For now the suspens is still here since none of the competitors seems to be really better than the other. The fight ends with two decisive rounds of idle observation. During the idle background, Amazon Prime vidéo dominates its opponent consuming 8% less energy. However, during the idle foreground, Netflix consumes 3.5% less.

The bell rings, end of the match ! The fighters having both won 2 rounds, the final decision will be a points decision.

The winner

After counting the points and despite an extremely tight score it is Netflix which is declared winner by the judges, 12.1 mAh to 12.4 mAh.
