What's worse than leaving your iPhone in a hot car every day?

Question

Plugging your iPhone in to charge +*before you go to bed every night*+..... and I would guess that's what most people do.
Seriously, if you believe in the first chart of this well know battery site - http://www.batteryuniversity.com/parttwo-34.htm - you can see that a Li-ion battery suffers more permanent capacity loss, for any given length of time, by sitting at 100% charge, then it loses by sitting in 104F temps on a partial charge. (After 1 year, 20% loss from 100% charge @ 77F, vs 15% loss from 104F temps with a 40% "storage charge.")
So, given that it takes about an hour to fully charge an iPhone, if you plug it in before you go to sleep, it ends up just sitting there 5-7hrs at 100% charge and probably worse off than leaving it in a 104F car for the same amount of time.
Solution... try to minimize the amount time that the phone sits at 100% charge and maximize the time it sits at about half charge (40% being the ideal storage charge) by:
a) Getting a light timer (about 4$) and set it to charge your phone the hour before you normally wake up. Let the phone sit at a lower charge level all night while you sleep. No difference to you, as you still plug it in before you go to sleep.
b) Getting a AA back-up charger (iGo, Duracell, Adrenalinetechnologies "Turbo Charge" make them) so you don't always have to worry about "topping off" the battery. (I'm not fond of Li-ion backups for the above, and other, reasons).
c) Use partial charges when appropriate. (Note that partial charges may require more recalibration, however.)
d) Anyone got any other ideas?

Answer 1

I think you are talking trivialities here. That chart refers to long term storage, not short term situations like overnight. Second, while Isidor Buchmann knows his stuff no doubt, that web pave is 4-5 years old, and current Li-polymer batteries have made pretty big advances in just the last couple of years. And third, since for most iPhone users, the battery is going to have an effective life span of 1-2 years (400-500 full equivalent charge cycles) at most, the slight loss in capacity directly attributable to sitting charged over night is hardly worth fussing about.
I just see it as way to much ado about nothing. There are far too many legitimate things to worry about every day - this is just not one of them.
P.S. And I do leave mine plugged in overnight, in a dock, since it is my alarm clock and quite honestly, I don't want to have to remember to plug it in come morning when I'm running about trying to get out the door to get to work. I just want to be able to grap it at anytime and know it is fully charged and good to go. I plug it in when I get to my office - I plug it in whenever convenient, regardless of charge state.
