Everything I've ever heard about Li-ion batteries suggests that a full
discharge damages the battery and reduces its life expectancy. I've
seen recommendations not to allow the battery to go below 20%, and
other suggestions to aim to keep the battery in the range of 40-80%
(possibly with an occassional 100% charge).
Well, the problem is, I have no way to know how much battery I have
left. The statistics are completely incorrect. Which means that even
though it shows something like 56%, it actually is 0% and it turns off
by itself. And 56% is not my new 0%, meaning the phone may die with 60%,
20%… So I can't really follow theses recommendations, my phone has
decided against it :). Plus, I bought a brand new battery and didn't
have the time to damage it.

I think Guillaume means he let the phone turn off when battery ran
low, not a real full discharge because, as you said, that is not good
for a Li-ion battery.
BQ has several articles [*] about this topic in general, and about how
to calibrate the battery in your BQ phone in particular.
Thanks for those articles! I don't read Spanish, and I can't testify for
Google's accuracy, but the article you sent me seems to go against what
you say (part of it at least). It's clearly written that you have to let
it discharge fully in order to calibrate the battery. It even goes as
far as suggesting we should do this once every two months. That's
exactly what I did when I replaced my battery, but it didn't stop my
phone from dying with supposedly 53% battery on the next discharge.
