Is android mining worth it? - The Gridcoin test

Four months ago, one of the first articles I read on Steemit was a question raised by Hive account@trumpman whether Gridcoin mining on Android is worth it. Like Hive account@trumpman, I had also an Android lying around catching dust. It is a Nexus 7 (2013) which is nowadays an average performing tablet. Here are the specs:

To get some more facts on how much I could gain from this tablet and which projects would be providing the highest returns, I decided to run all whitelisted projects with Android support. At the moment there are 11 projects supporting Android but during the test I didn’t manage to receive work-units for Enigma@home so I had to leave it out.

When I initially started to run BOINC on 4 cores, the tablet became really hot so I reduced it to 2 only. I ran every project for 5 days (24h per day) to calculate the maximum achievable RAC (after 5 days a system reaches roughly 40% of max RAC output).

In the table below I have presented the results of the tests. I was surprised that I could earn 0.2 GRC per day with some projects, which is not bad. By comparison my i5 laptop with 4 cores achieves maximum 2.5 GRC per day for the same projects.

The 3 highest earning projects for my tablet are Yoyo@home, theSkynet Pogs and Universe@home. Due to the fact that the difference with the rest of the projects is so big, I can imagine that this will be the case for other tablets and smartphones as well.

Thanks for reading and follow me for more Gridcoin-related articles.
