I don't think my battery is better as a result of that anymore, but I did do it and my battery seems to get what apple describes as normal life.
I don't think it matters whether you use the pc or wall outlet or car adapter.
I've noticed that charging all the way to 100% seems to enable me to get more time between charges. Specifically, after charging it to 100%, it seems to run quite a while before it drops to 99%. But, if I only charge it to 96%, then it starts dropping immediately. But, to charge it to 100% seems to take quite a bit longer than just 96% or 99%.
So, that makes me think that the battery usage is not linear.
And, I've also noticed this on the low end. For example, when on standby, my iphone runs down from 25% to 3% and then sits there for hours, going from 3% to 0%. This may be intentional by apple because it gives you a little more warning to find a power source and plug it in before it shuts off.
I always notice that once it shuts off at 0%, it seems to take 5-10 minutes before it will start up again after being plugged in. Obviously, if you're on a call, you don't want to have to wait 5-10 minutes to call someone back.
So, this is what I've learned about the battery.
Regarding getting more life, I'd say reducing the backlight has the biggest impact of anything I'm willing to do.
I don't care to stop using LTE or icloud or wi-fi, but I don't have any bluetooth, so keep that off always.
