    This is the first time I am using my iPhone 5. Should I let battery drain completely?

    I did a bunch of research and figured out that nobody knows. Personally I'm letting it go to 1% then charging full.

    Some people who are experts claim "let it die first" then another expert claims "don't, new lithium batteries are fine" me personally. I let it die, then charge it all the way up. But that's just me haha

    I wanted to test battery life and I am letting my drain to 1 percent. As I type this at two percent with almost 8 hrs of usage and over 1 day standby. Figure that is pretty good

    It was an issue with only batteries but batteries these don't need that, but I always do it to every device that I own just a force of habbit, I usually do it the first 2 times then I let it go

    Draining Li-ion batteries too low can damage them. The occasional calibration isn't too bad, but draining it for the sake of "memory issues" is not valid where Li-ion batteries are concerned and in general is a bad practice.

    These LI-ion batteries come pre-conditioned from the fActory and they only need it the one time.

    Yes! If my battery life is any indication, yes you should. Mine is 9% left with 10 hours, 10 minutes of usage, with 1 day, 3 hours of standby. Far better than I've ever gotten with the 4S.

    I'm draining my battery down right now because I don't see any downside. I've been stuck at 1% for more than 15 minutes now while playing a video. This makes me think that some "calibration" is in order since now I don't think the 1% was accurate when began the video.
    We'll see.

    Just use it till the end of the day and charge it while you sleep, repeat daily.

    You will get a hundred different answers for this. Bets to just ignor and enjoy your phone.

    Draining my new i5 to 0% three times in a row DRAMATICALLY improved the battery life.

    However, now that I've cycled it 3 times I will only be doing so like once a month.

    Nobody is sure whether the new phone cycles help the software calibrate to give you more accurate readings or if it actually helps the battery itself. Probably the former.

    Either way, give it a shot. Worked well for me.

    GL! :)

    My friend thought the same but even after running it down till it stopped, the phone did the same thing and ran for a LONG time after it got down to 1%.

    It is just like your gas gage and you can still have plenty, even when it say Empty!

    I had the same exact results. Every drain cycle my battery increased significantly.

    Now I will charge as needed.

    Never have followed any of that battery hocus pocus and have always had good battery life.

    Some of us would like great battery life. If "good" is what you want than you probably don't have to bother with all that hocus pocus nonsense :)

    Draining the battery completely is an old caveman/fool's idea of how to condition a battery. It's not necessary with lithium ion, and it can actually have negative effects.

    One would have done this with other devices with ni-cad batteries.

    As always, consider the source. Sounds like you need to do a better job of vetting who is and isn't an expert.

    And, as always:

    Lithium batteries don't have any memory effect, so any calibration of the battery itself is not needed.
    Apple suggest to let your device go to 0% once a month to calibrate the battery sensor.

    Be sure to go through at least one charge cycle per month (charging the battery to 100% and then completely running it down).

    Thanks for the coaching session. But again, others claim different. I wasn't saying who was right or who was wrong, i was saying what ive heard from so called "experts"

    Yeah, any "experts" that tell you Li-Ion batteries need discharging are flat out wrong. The only benefit of discharging is to allow the charging system to calibrate against the battery's effective life. I don't even think once a month is necessary as the battery life won't change that often (except perhaps during the first few cycles when it actually increases in life).
