We spend a lot of time on our phones - so it makes sense if our batteries usually hit that dreaded 10 percent mark before the day's even half over. That's why it's important to stock up on chargers whenever you can, and now you can re-up on three extra-long Lightning charging cables for a fraction of the cost.

Hey Lifehacker, Is leaving a device plugged in to a charger actually all that bad for the battery? I know it's not that great if it's left in for days on end, however I've found that a few hours does no harm. Any thoughts?

Dear Lifehacker, What is the deal with lithium-ion batteries (the kind found in smartphones and laptops)? I've heard lots of different things about how to take care of them, like that they need to be kept charged between 40 per cent and 80 percent, or that they should be drained completely and charged to 100 per cent.
