For those interested, I went with the Bokman. Professionally packaged,
fairly good tools with it, although I have a decent toolkit already.
Replacement was more fiddly than the iPhone 5s (that's plural iPhone 5,
not 5 ess) I've done before, but all good.
After charging it up to 100%, it took 27 hours of watching films,
leaving it in the bathroom where there is low signal strength so it has
to boost its signal which is one of the biggest sucks on battery, and
various other power hungry uses, to run it down til it turned itself off
from low battery. There seems to be a variety of opinion about
"calibrating" Li-ion batteries, but iFixit recommend it and they seem to
know what they're talking about. Other knowledgeable opinions welcomed.
My understanding is that it doesn't so much calibrate the battery as the
management software, so isn't strictly necessary and may possibly not do
the battery any good, but makes the % reading more reliable.
