Freeplay Zero finally done! Pictures and final thoughts

[Flavor]

Those numbers (5-5.5hrs) were done with a Pi Zero (maybe even before the Pi Zero W came out). We tested it several times and got very consistent results. We would usually run a GBA game and let it run it intro/attract mode until the battery died.

There have been changes to the software since then, but I can't think of anything that would impact the battery double (like what you're seeing).

If you can do a more scientific test, that would be quite helpful. I'm wondering if one of your batteries isn't fully plugged in or isn't working properly. If it was almost exactly half the battery life, that would be my first thought.

If you do some testing, maybe try with only one battery. See what you get. Then add the second battery, and see if you get double whatever your first result was.

Just as a bit of added info, I believe that the RetroModding cells you have would be the 753050 batteries. Here are our original tests using singles of those (which is somewhat consistent with the results you mentioned).

1000mAh 753050 Cells (tested using GPA v2.0)
Size: 7.5x30x50mm each
Single Cell TEST 1: 2h 24m
Single Cell TEST 2: 2h 35m
Single Cell TEST 3: 2h 38m
