EDIT: And you have to glue a plastic pin like in official TOH's to the panel next to the battery so the microswitch will trigger. Won't charge without it.

This is brilliant stuff! I'm really impressed and excited by this!
@skvark - I downloaded and printed a copy of your 'other half', it came out really nice, but sadly, it doesn't quite fit the phone in the length.
It was that tight that it started to bow the phone so off it came!
I used Netfabb Basic to cut a section from the lower half of the model and stitched it back together in Blender.
I'm going to my friends tomorrow to print it off, hopefully it won't be so tight!, perhaps we have some settings wrong on my mates printer, but when we measured the model the dimensions were as you set them.
Has anyone else experienced the same thing?, I've added 1mm to the length of the model to compensate but I will also check the software for the printer again.
Any info appreciated.
Regards
Mark

I will post back later tomorrow after another printing session!

I did some measuring with the CSD tool (= phone is in airplane mode and I have turned the tohd.service off). Charging current under the 70 W lamp stabilized to 50-60 mA and some spikes go to 70-80 mA. If the CSD tool can be trusted (and the panel is actually charging the phone, like the phone and the tool says), there should be about 1% more battery every ~30 mins. To confirm this, I ran a short test:
I started testing at 18:00 (battery level was 85 %). Strange thing is that the UI does not update the battery level without a reboot (bug?). So I rebooted the device couple of times during the loading period. After every reboot there's was always 1% more battery level. Reboots were at 18:45 and 19:45. After the second reboot device reports battery level of 87 %. So getting 1% takes more than 30 mins.
Some conclusions:
- the 1W (125x36mm) panel is enough to upkeep the battery level and to charge the phone very very slowly (under a lamp, sunlight it would be maybe 2-3 times faster)
- for faster charging more efficient panel is needed

125x36mm = 0.0045 m2. At full sumlight that should receive about 5W of energy. The best solar panels have about 20% efficiency. So it is not even theoretically possible to get more than 1W from a solar panel of that size without revolutionary technology advances. Sorry.
The panel size is actually 125x63 (made a typo, not 36mm), so it gets close to 2W.
