    Was wondering whether the iPads and iPhones ,should they be charged once almost all charge is discharged or anytime would be fine .I don't normally wait for it to get below 30 except in rare occasions .Does this make a difference .

    It doesn't make any difference. Just charge whenever convenient for you.

    Just remember to let it get below 5% every 2-3 months before fully charging to 100%.

    I kill mine fairly often. Though this time I appear to have actually killed it (lol)

    Lithium batteries prefer to be charged between 40 and 80%, they will last longer that way. However, to calibrate the battery we should let it go to 0%, charge it to 100 and do the same thing again. this should be done from time to time only, like every couple of months, not more.

    You do not need to "optimize" your battery at all. Lithium-Ion batteries do not require the refresh cycles of Ni-Cds or Ni-Mh. You can charge them whenever you wish. The only risk is leaving a discharged battery in that state for a long time. (copy/paste)

    I agree. Charge at your convenience. If you're going to leave the device idle for more than a week charge to 50% prior to storing it.

    Nope, "calibration" is a myth with modern Li-Ion batteries

    Read here: "These smart batteries supposedly reduce the need to calibrate, though its still recommended when your battery behaves oddly. If you see the battery percentage on your phone jump around a lot (like you could have sworn it was fully charged, and now its at 20%,) its time to calibrate it.*"

    Not overly. We get this question every time a new device is launched and you can bet we've checked the answers again and again, year on year.

    I'm a former Ambassador to iMore and I remember this question being asked last year and the year before, and the year before that too. The answers were the same: It doesn't matter anymore. It used to matter, now it doesn't.

    Good thing it doesn't matter, I've never paid attention, lol. But i did notice that the 7 Plus has a tantric battery life.

    Amen...

    Let me repeat... It used to matter, now it doesn't.

    Period.

    I jumped in one of these threads a year ago (maybe two years ago??) and did a bunch of actual engineering research (not Lifehacker articles...) and Li-Ion battery "calibration" and "memory" is a MYTH and they actually are designed to be trickle charged as necessary.

    Quite the metaphor lol, but yes -- the bigger the battery the longer it will last...

    You should let your cellphone battery drain below 5 % once every week because if you will charge the battery before it drains to 5% every time then it will decrease the battery time and battery life for your phone.
    100% false information. Sorry.

    I know and I agree, but there is a ton of threads about this and in all of them, there is always someone saying "no no it's a good thing to drain the battery regularly"
