Does iphone lose battery when powered/turned off??

So my lock button at the top of the iphone 4 doesn't work and i used the assistive touch button to lock screen when needed. The reason i didn't go to apple store is that i have past my warranty and didn't buy apple care.
Anyway, the other day, the iphone shut down unexpectedly at around 40%.
Now, normally, if it shuts down, it'll only be because of the battery being lower than 4%, and so all i had to do was to it in to power adaptor.
BUT, because i know that the percentage left is closer to 40%, then i was wondering whether the iphone would lose battery. Because if that happens, i can just wait for a couple of hours before plugging it in....

All devices use power when in sleep mode.
Locking the screen does not turn the device off, never has.

My iphone 4 turned off yesterday very randomly. I had 88% battery when it turned off. I plugged it into the wall and it said i had no battery, then the apple came up as if it was turning on. It went black again and this keeps repeating. Any help please ?

Battery could be at EOL. Try getting it replaced.

IPHONE photos erased when you turn off the phone

I have a new IPHONE 3G phone .I can take pictures with the phone which are fine until I turn off the phone. When I turn it on again the photos taken with the IPHONE have disappeared.

The red arrow on the screen when you hold the top button down for a 3-5 seconds is the Power Off slider, which you move across the screen with your finger. Just pushing the top button momentarily puts the phone to sleep. Either way, the photo should be saved. If the photo is not saved to Photos>Camera Roll (and you are sure you are looking at Camera Roll and not another Photo Album), then you must have a corruption somewhere. If the Restore did not work, the only other option besides taking the phone in to Apple is to do another Restore and don't put anything back in until you try the Camera function, just to rule out the possibility that you are reloading a corruption. I've seen no other posts here about this, but it might be worthwhile to do a search and see.

My iphone no service when i turn off the 3g option why!?!?

well sometimes i just use my data and turn on the 3g option but when the data is off i just turn off the 3g and its said no service why?? (sorry ,my english im from panama so well )

Try a reset by pressing the home and sleep buttons until you see the Apple logo, ignoring the slider. Takes about 5-15 secs of button holding and you won't lose any data or settings.

I just got my battery and iphone 4 screen fixed and when it turned off because there weren't any battery left, I tried charging it. Now it won't turn on or charge... what do i do?

I just got my battery and iphone 4 screen fixed and when it turned off because there weren't any battery left, I tried charging it. After charging it for like thirty minutes, I pressed the home & lock button and it turned on for a moment for me to see that it was only at 1%... So basically it wasn't charging for that entire half hour. Then, I tried connecting it to my computer and nothing is popping up... so it won't turn on or charge... what do i do?

Who repaired the phone? I suggest taking it back to this repair facility. Since Apple replaces phones instead of repair, the repair facility would be the one to take care of your problem.

When you turn on the ipad2 it does not start up properly. The rotating disk that happens when you turn off the ipad appears after the apple logo comes up

When you turn on the ipad2 it does not start up properly. The rotating disk that happens when you turn off the ipad appears after the apple logo comes up during start-up and stays there for ten minutes. Then, the ipad will start up properly.

Have you tried a reset ? Press and hold both the sleep and home buttons for about 10 to 15 seconds (ignore the red slider), after which the Apple logo should appear - you won't lose any content, it's the iPad equivalent of a reboot.

My new ipod nano does not work when you turn off the computer

I bought a new iPod but I have a problem when you turn off the computer does not work. Shows that the battery is full and it was lightning. Ipod only works while connected to your computer. What should I do

Hello pepi95,
And welcome to Apple Discussions!
If you just bought the nano, why not bring it back for a replacement or your money back? It's definitely a defective iPod. Not much else for options here. Sorry.

Anyone know why my iphone 4S backlight is not turning off. Started when I upgraded to IOS 7.3. Its keeps draining the battery and I am constantly recharging it

Nano battery continues to drain when its turned off..why?

my nano battery continues to drain when its turned off..why?

Have you updated to the latest software? Connect to itunes and hit the update button on the summary screen for the ipod to find out. If there is an update, install it.
Usually, your battery drains when your not using it because it is still playing. As of the 1.1 udpate, they have a feature that tries to preserve your battery life. If you unplug the headset, this feature works to save your battery. So with the latest update, if you unplug your headset when you are done listening, it should put the nano to sleep so that it does not drain your battery.

Charge your iPhone whenever you want to. There are no limitations on when or the duration of charge. Normally it will charge in 3-4 hours with the wall charger, longer if you use a computer USB port.

Your problem is that she used your icloud ID to connect to icloud and thus had all your data synced to her device. Contacts are not saved in a backup to icloud, since they are stored independently in the Contacts section of icloud. If someone deletes them, they are gone. If you had them on the PC would they be available in some backup you frequently make of the PC?
