Charge iphone 5c/s at least 40%???

I'm worrying again about charging my iphone. Is it true that you MUST not charge your iphone below 40 or 30% because this is a li-on battery??! Please clear my question because I notice that my iphone 5c is draining too fast and i followed already those steps on how to preserve the battery. I usually charge, for a half-month, at 1%. Please answer me! Thanks!

It is harder on the battery overall to always allow it to near depletion. That is not saying it can't or shouldn't be done, just not every time.

My iPhone 3GS battery loses at least 30% charge when off for at least an hour

My iPhone 3GS battery loses at least 30% charge when off for at least an hour, I took it in to an apple retail store at the end of 2010 and they told me it was fine but advised I restore and set up as a new iPhone which I did, it got better for about a month then went back to normal losing battery. I have no hardware coverage left and my specs are: iPhone 3GS 16gb IOS 4.3.3 white. I have had it since December 2009.

I'm afraid I don't. I don't know if the phone is still within warranty. I don't know which country you are in. I don't know what third party repair companies charge where you are.
Hang on - I do know one thing: if your phone is still covered by warranty - it's free!

I have Exchange and Yahoo accounts on my iPhone 4. At least 1 email a day I send as a reply fails to leave my outbox of my Exchange account.

I have Exchange and Yahoo accounts on my iPhone 4. At least 1 email I send from out thru my Exchange account fails to send and it simply refuses to leave the outbox. The only guaranteed way of sending it is to change the sender to my yahoo account. Note that is ONLY occurs on replies to existing emails, never new emails.
It is only certain mails that fail. Even if I delete the mail and write another reply it will still fail.
Could it be content related? It happened on IOS4 & 5.
I've asked one of the staff in the Apple shop and he said he's seen this before but doesnt know the answer - not really helpful if you're trying to work off your iPhone :-(

Thanks razmee209.
I would agree with you if I still couldnt send the reply by changing the sender to my yahoo account; but as I mentioned before - whenever the mail fails to send, I can ALWAYS send it by changing the sender to my yahoo account.
I agree that it must be something within the original mail, but why does it trigger a failure if I reply from my exchange account and not my yahoo yahoo account.
I can delete the Exchange account and re-add it, but it makes no difference. I've also rebooted the phone but again, no difference.

Charging iPhone with closed lid on mbp

I've been researching, but found nothing this specific so far. Related links:
- http://support.apple.com/kb/HT1476 - This says it may or may not charge
- http://forums.mactalk.com.au/11/72536-snow-leopard-not-charging-iphone-while-lid -closed.html - This says it should work since Leopard and if it's not working to reset the SMC should fix it (I haven't tried yet): http://support.apple.com/kb/HT3964
- http://forums.macrumors.com/showthread.php?t=795007 This is not the same model, but for him it seems to not work anyway
- http://discussions.apple.com/thread.jspa?threadID=2126178 Suggests http://support.apple.com/kb/HT3131 for dealing with closed lid, but requires external display, among other things that don't come to this case (or so I guess)
To me, experience showed that closing the lid with the iPhone already connected works fine. I'm using a macbook pro 2009, as already hinted elsewhere. It's 13'' if that makes any difference.
But if I have the computer sleeping in the bag and want to just plug the iPhone for charging convenience, then it doesn't work. I have to remove it, open the lid, wait for charging to begin, then I can safely close, sleep, put it back on the bag, and it will be charging.
So I wonder how this is supposed to work, and if I can "fix" this behavior. Anyone knows?

I actually solved it on my own luck. Oddly enough, just need to remove and re-plug.
Here, this is a small chart:
1- Computer with lid open, up and running with energy - whatever AC or not.
normal behavior, everything as expected: plug in iPhone it starts charging.
2- Computer with closed lid, sleeping as blinking light indicate and plugged in AC power.
normal behavior, everything as expected: plug in iPhone it starts charging.
3- Computer with closed lid for long time, unplugged from AC power, no cables on it whatsoever.
plug in iPhone - nothing happens.
unplug it and plug in again in either port - it starts charging!
If you close the lid and don't wait it gets to sleep (that is, white blinking light - if you want to be sure, wait till the computer cools down, if it was hot - that's sleep mode) you'll get normal behavior right on the first plug time. The trick of plugging again seem to work always from my tests. So this is a undocumented feature that took me freaking long enough to uncover!
Now it's aight!

The hotels I stayed in during my visit to the Holy Land had a plug for electric razors which has the same plug used in the US. With that I didn't even need the adapter.

How to charge iphone 5 correctly

Hi everyone,
So Apple says to do a full cycle charge once a month (charge iphone from 0% to 100% and then do a reset) right?!
But during everyday use should I charge the phone for bit during the day? Or just charge every night before going to bed?
When the 20% alert shows you must charge the iphone to avoid a complete cycle charge?
Any suggestions?
Thank you

The purpose of the full cycle charge is to recalibrate the battery gauge. Lithium chemistry batteries are notoriously hard to manage, because their voltage does not drop linearly with state of charge, as most other secondary cells do. So the battery gauge monitors battery charge going in and battery drain going out, and computes the remaining life from this. But the battery's capacity drops with age, and the calculation isn't perfect. So after a while the gauge no longer knows what the state of charge actually is. The most obvious symptom of this is when the phone suddenly shuts off well above 1% remaining. When you run the battery all the way down, then charge fully, the charging circuit in the phone can re-establish the end points.
Anyway, the answer to your question is charge it whenever you want, except that you should periodically run it all the way down, then fully charge it (once a month, as Apple suggests). But not every day. According to Apple this does not affect the total lifetime of the battery.
Oh, one other point. The iPhone will not let you deep discharge the battery. When it shuts off at 1% there is still significant charge left. It's unusable charge, except to keep iOS alive. If you fly a plane there are 2 numbers you need to know - total fuel capacity, and useable fuel capacity, which is always lower. Same with Lithium batteries in electronics.

Unable to charge iPhone 5

unable to charge iPhone 5 cleaned out the charging point and even had a new battery fitted

The iPhone charger is 5W while the iPad charger is 10W. Do neither work to charge the iPhone or iPad? Since you can charge (slowly) via the computer, the cable is good.
Take it to an Apple Store for evaluation.

Is charging iPhone 4 with USB connection in 2012 Toyota Sienna safe?

Is charging iPhone 4 with the USB connection in 2012 Toyota Sienna safe?

Sure. I have been using the USB charge/music interface in my Toyota truck with my iPhone for almost 2 years, with no issues.

Fully charged iphone 4 died will not reboot.

My fully charged iphone 4 died mid conversation yesterday. I tried turning it back on with the sleep/wake and home button with 2 different cables and two different chargers. I tried this again with both cables with it connected to my macbook. Nothing. Apple phone support had me retry everything i had done including trying to put the iphone into recovery mode still nothing. So at my wits end i setup a genius appointment for 12am at the 5th avenue apple store in manhattan. (great staff by the way). The Techs confirmed non of the conventional suggestions worked. In the end they did exactly what i would have done had i had a 5 star screw driver. Take the battery out, put the battery back in.
BAM.
Not dead iphone. Hope this helps someone.

Have you tried to reset the iPhone by pressing and holding the sleep/wake button and the home button for 10-15 seconds until the Apple logo appears, ignore the red slider. Then turn back on. You won't lose any data doing the reset.
