Understanding iPhone Charging and Power Adapters
I've been in a protracted discussion (now locked) regarding iPhone battery charging and whether it is harmful/helpful to use the iPad power adapter rather than the iPhone power adapter.
There are a lot of misconceptions related to iPhone charging and current ratings on the iPhone and iPad power adapters. As an electrical engineer, I'd like to clear up some misconceptions.
Apple supplies a power adapter, not a "battery charger," with the iPhone and iPad.
The iPhone power adapter supplies a constant 5V at up to 1A (rated–independent tests have shown that it can supply almost 1.8A).
The iPad power adapter supplies a constant 5V at up to 2 or 2.1A (rated).
The iPhone's battery charging voltage and current are regulated within the phone.
The iPhone's battery is rated at 3.7V. Charged with the raw 5V from the power adapter, it would be destroyed. Fortunately, the internal regulation in the iPhone prevents that.
The maximum current that an iPhone will draw from a 5V power adapter is right around 1 amp. It does not matter if the charger is capable of supplying more, that's the most that the iPhone will use.
Because of the internal charge regulation, the iPhone battery will not charge any faster on an iPad power adapter than on an iPhone power adapter.
Apple approves the use of the iPad power adapter with the iPhone. It is completely safe for that purpose and does not harm the phone or battery in any way.
A water analogy might make this much easier for people without electrical engineering background to understand.
Water pressure (psi) is analogous to voltage.
Water flow (gallons per minute) is equivalent to current flow (amps).
A faucet valve is analogous to the iPhones battery charging regulation circuitry.
A bucket's capacity (gallons) is analogous to a battery's capacity (amp-hours or AH).
Let's say you adjust the faucet to flow 1/10 of a gallon per hour. The five gallon bucket will take 50 minutes to fill up. Easy enough. But then...
You need a lot more water flow for a new sprinkler system.
You need a lot more current for your new iPad.
Since the water pressure is constant at 80psi, the only way to get more flow use a bigger supply line.
Since the voltage is constant at 5V, the only way to get more current is to use a higher current power adapter.
After installing the new higher capacity water supply line, you go out to your faucet and adjust it to 1/10 of a gallon per hour.
After plugging in the higher capacity iPad adapter, you plug in your iPhone and its charging regulation circuitry adjusts the current flow to about an amp.
The bucket still takes just as long to fill up.
The battery still takes just as long to charge.
The faucet is not under additional strain since the pressure is still 80psi.
The iPhone's battery charging circuitry is not under additional strain since the supply voltage is still 5V.
I hope that I've clarified this for those who want to better understand the subject.As far as the battery status, the tiny little icon in
the upper right corner of the screen is somewhat
helpful, but while it is connected it does not
actually indicate the level of the charge or that the
Iphone is charging. I was hoping to find a more
informative screen that would give better battery
details. When you first connect the iPhone sometimes
I get a large battery icon that shows the level
visually Is there a way to navigate to this screen?
1. Press the top button to turn the display off if it's not off already.
2. Connect to a power source.
3. The screen should display a large battery meter in the middle of the screen that actually shows the state of charge, even if charging.
If you don't see this plugged into your Mac try the AC adapter that came with the phone. If you still don't see it take it to an Apple store.

Iphone 5s and Power Monkey Explorer
Hi
Please can you tell me if I can charge / run my 5s, using the supplied Apple lightening to male usb cable, from the female usb connector on my Power Monkey Explorer? I've not tried in case the pins in the usbs are different.
Thank youYes, the power button is somewhat loose on my 5s. I've never really thought about it that much. It's a non-issue for.

I recently made the mistake of buying a cheap sync cable from a well known auction site becuase I wanted a longer cable than comes in the box for my ipad 2.
Whilst my iPad will sync OK, it takes an age to charge (using the standard 10w plug in the wall). I don't fully understand the science in the cables, but assume it is not a big enough cable to handle the current/2.1 amps?.
If like house wire you send too much current through a cable that is to small for the job it risks overheating and causing a fire.
Does this same principle apply to the iPad power lead?
Anyway back to the question, can I use other leads I have hanging around the house from my previous iphones and ipods to charge my ipad (again still using the 10w plug in the wall) or will the cable in these be too small to handle the 2.1 amps required by the ipad?
I don't want to risk overheating the cables and causing a short to break my beloved iPad 2...!Thanks for your replies.
Not sure they entirely answer my question though.
I have used my different cables and can see that they are actually working (charging and syncing etc), but am i using old cable that was not intended to draw 2.1 amps and so may overheat and cause damage in the long run?
Or did apple deliberately over engineer the original cables which were only needed to supply 1 amp and they can actually be used to draw 2.1 amps comfortably?
Whilst the 30 pin connectors and usb points are identical, is the internal cable thickness/awg gauge the same?
Thanks -
Decided to update iphone 4 to ios 5.1 and mid update it froze and the screen is black. Phone does not respond to any combinations of home and power buttons, when plugged into computer it does not see it is plugged in so I cannot restore or anything. Looks like the screen is on it's just unresponsive and black obviously. Has anyone had this problem? I was updating via wifi right in front of my router and my computer.
Spoke to a "senior advisor" in the Apple TV department. Her suggestions: change channel in router to minimize/eliminate wifi interference from other users; move router away from any metal - i.e., DVD player, phone modem, etc.; keep router away from wireless 2.4 gH phones, which are "notorious" for crashing wifi routers. So she confirms that the problem is one of connection to router suddenly dropping out.
My own feeling is that none of these fixes will do the trick, because it seems pretty clear that there is a hardware component here - the timing of the drops seems like an overheating issue. It takes 35-40 minutes for the box to warm up enough for the first drop; then each consecutive drop happens quicker than the one before, as it heats up more. Each time it drops, its tiny brain gets a little more scrambled; last night it finally wouldn't start up again at all.
My suggestion is that everyone who is experiencing this problem, please call Apple tech support and ask to speak to a senior advisor in the Apple TV department. Make them aware of this problem! -
my iphone 4 is stuck on the reboot logo, ive ried holding both home and power to shut it off snd then keep holding home to let you plug it into itunes but it doesnt work. what do i do?
Did you try rebooting the iPad? You will need to have some battery power for this.
Reboot the iPad by holding down on the sleep and home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons.

Help with using itunes with 4s library after i upgraded to iPhone 5 and computer power supply went
long story hopefully an easy fix....
on wensday my power supply went and had to ship computer across country to Puget Computer Systems as we weren't sure if it was power supply or mobo...luckily it was power supply.
i daily backed up iphone 4s with itunes (10.7) as i do all music manually, playlists, etc. have like 3,000 plus songs, videos, audiobooks, mail aaccts and about 48 apps.
so next day (sept 19th) apple comes out with iOS 6 which i update my 4s to with no problem. I wanted a day to play with it to learn my way around.
next day i wait in line for 8 hours overnite and was #2 in line at apple store for my ATT 32gb white iPhone 5. while at apple store I get my icloud backup which gets all paid music,apps, etc since itunes version 10.3 (i always did both backups so as not to lose my contacts more than anything.
I have other paid stuff that is in library on computer along with audiobooks and about 2700 more songs.
my icloud backup put the playlists on iPhone but not most of the music for them as lots were ripped from my cd's.as i double them up making a copy on iPhone and a copy on itunes.
So I have been using iPhone 5 with no problems just don't have all of itunes library on it. My computer is coming back this week how do I plug in iPhone 5 via USB (which will be seen as new phone even though it has same name) and use my existing iTunes 10.7 library which the backups in iTunes still has iOS 5.1.1 on it?
There must be an easy way of doing it as i don't want to wipe off iphone 5 again as i don't see any purpose my library is all organized perfectly. I know my way around windows 7 pro 64 bit pretty well just don't know what itunes is going to say once it sees "joe's iPhone" again and installs the usb drivers and icon for it. what will it ask in regards to library and how do i use it with previous iOS on it?
Thank you very much for the help as I am going to need it.
yes i broke the cardinal rule of cross posting and apoligize for it just amazed i couldn't find answer via google nor any apple store genius knew it either.Hi All,
Any help?
No one has any answers here amoungst all this apple knowledge?
Thank you -

IOS7 installed OK to my iPhone 4S and worked OK for a while but I have somehow managed to completely jam my iPhone 4s. The touch screen won't work except for up and down gestures (some of the time). I can't make or answer calls, I can't even power if off. I can't access the hardward ID which Apple support seems to require for Chat.
It might have happened when I was accessing my camera bypassing the lock screen!
All I know is that the thing is now useless and it looks like I will have to wait for the battery to run down to see if powering it back up afterwards will solve the problem.I have since discovered the "hold down home key and power button" together for a few seconds and this seems to have worked .... phew!

How can I do a hard reset of iPhone 5 if iTunes and power buttons don't work?
My son's iPhone 5 will not go past the screen with the little blue iTunes logo up top and an image of the charger on bottom. I've tried syncing to iTunes to restore but receive an error message after it goes through updates. The error reads, "There was a problem downloading the software for the iPhone "iPhone". The network connection was reset. Make sure your network settings are correct and your network connection is active, or try again later." So then I try holding down the power and home buttons to get the Apple logo but then the initial screen comes backs (iTunes logo/image of charger). This phone is really not THAT old so there has to be a solution out there.
The error that you are seeing has to do with your Internet connection. Try disabling your anti-virus software and connect the iPhone again and try to restore. See this support document for help. http://support.apple.com/kb/HT1808

Since I have upgraded from 7.1 then the power consumption increased slightly unbelievable. I have new batteries in my iphone 5 and when I had at ios 7 so was consumption that allows the battery envelope in two days and with ios 7.1 so is it only 12 hours before I need to recharge the battery.
Wrote a little wrong the first time!

I have reached out to this community as my Iphone display gone black and got the solution to keep home and power button pressed. It worked but I would like to know
1. Why it went black and is there a permanent fix for this
2.Will the IOS gets automatically updated as I feel the IOS was 5 when I got the phone in 2012 december
3.Do you suggest 7.1 for Iphone 41. There is no way of knowing. These things happen.
2. The iOS only gets updated when you want it to be.
3. You should always update to the latest iOS your phone will support. Apple do not write the updates to make your experience worse. -
I dropped my iphone 4 and it shut off and when i tried to cut it on it wouldnt. so i connected it to a power source and it tunred on but stay stucked on the apple logo. so when i discounted it shut off. it only turns on when connected to a power source but not on its own. i tired to connect it to itunes no help, i tried to press the home and power button still no help.
Your last try would be a restore if you can get iTunes to recognize the phone. If not, you have probably damaged the device beyond repair. You can go to see Apple about an out of warranty replacement. The cost for the iPhone 4 is $149US, you can check for your location.

I dropped my iphone 4s and now it won't power up, I dropped my iphone 4s and now it won't power up
I just dropped my phone onto asphalt from the car, about a 2.5 foot drop. The phone was wearing a case and no damage was done to the phone. the phone was off when I picked it up and will not power up. Any suggestions for how to fix this myself?
Apparently some damage to the iPhone did occur. Using a case doesn't guarantee zero damage when dropped depending on the case.
If the iPhone won't power on the normal way and the same with a reset, make an appointment at an Apple store if there is one nearby. -
installed the ios 7.0.2 update to my iphone 4, now it is stuck on a screen with itunes icon and power plug.
I am unable to use the phone now. What should i do next? I plug in to itune in my computer and ask me to restore my phone? I will loose all my date?I hooked up itune and restore. after finished restores, it said my phone is in recovery mode and needs to be finish before using itune, my screen still show the itunes icon and power plug
