1%.

Usually minutes before it dies or a few hours after it dies. Depends I guess..

0%

Always before sleep so it depends. Sometimes during the day when it goes below 5% too.

After it dies mostly.

If I have to go out, for example, and it is less than 90% I already charge it

If not, I'll probably leave it until it dies or gets to 1%. But I usually leave it charging while I'm sleeping, so sometimes I connect it and it's still high like 50-60%.

10%

at about 40%. I try not to let it go under that (except once a month to re calibrate the battery)

10% because I know it's the last notification I'll get before the battery runs out.

2% tbh

0%

10% if im home all day but if I know im going out during that day and it's lower than 85% I constantly keep charging it

Whenever I go to bed, no matter the percentage. I just have this thing that my phone has to always be at 100% when I wake up the next day.

Plus, now that I have the iPhone 6 Plus, it's extremely hard for me to drain my battery to 0 within a day.

Whenever it drops below 10% but if I'm going out it has to be at least at 75%.

Like 40%

It's a tragedy when you have to go somewhere and its like 30-60%

Less than 9%, I recharge it!

When it dies unless I have plans to use it
