IPad 3 very hot w battery drain when streaming AirPlay!

Why does my iPad 3 get very hot and battery drains very quickly only when streaming with AirPlay?

Just in case anyone else is experiencing the same or similar scenario that I was (see first post), turns out that the Apple Care Geniuses determined that the PMU (Power Management Unit - I think the "U" is for "unit" anyway), was corrupted or not working properly, so too much power was being used for tasks that shouldn't have used up so much power.
They replaced my unit, it may or or may not be a refurbished unit, although it looks new and was manufactured on a later date than the one I brought in.
The Geniuses were very helpful and didn't just turn me away saying to "turn down the brightness or turn off WiFi when not in use" which I do anyway.

IPhone 4 very hot and battery draining fast

I am having an issue with my IPhone 4 that just started yesterday. It is VERY hot to the touch the screen and the back of the phone. It is also not maintaing a charge. I charged it all night and just taking it off the charger and not using it till I checked the time one time it was down to around 96%. I talked on it for maybe 5 - 10 minutes and only talked and it was down in the 70's. By the time I picked it up again once in the office to check battery power I noticed it was down in the 50's. I am constantly having to charge it and cannot stand to hold it in my hand due to it being so hot. Any advice or ideas?

There is Most likely a Probem with your battery, I would go to the Apple store to see if it can be fixed or replaced.

My iPhone 5 is getting very hot and battery drains quickly.. normal?

I've been having a variety of signal related problems with my iPhone 5 and I'm wondering if anyone can offer any advice. From day 1 I have observed that my phone will have poor signal strength or will switch from 4G or LTE into Edge mode, even if my wife standing right next to me (same network same iphone 5) has better signal. Phone also frequently gets quite hot (to were it's uncomfortable to hold).
I did a long hike last weekend and in the space of 3.5 hours, while doing nothing but listening to music and taking a few photos, the phone was nearly drained (20%). If I tried to take a photo it would simply shut down after pressing the shutter button. I also had no signal (phone was searching), even though other AT&T iphone users around me had signal and were texting, making calls and sending photos (this was from a mountain top so the temps were quite low).
Apple diagnosed the radio in my phone and said it is fine (good attenuation and no dropped calls). They recommended that I wipe the phone and set it up as a new phone versus restoring from a backup (what a pain). I did this and while returning from an outing yesterday I had 3 bars of LTE signal and noticed that with just light browsing the phone got very very warm and the battery was draining quickly. In the space of just an hour the phone plummeted from 75% to 30%.
I'm trying to determine if all of this is "normal" or if I should demand a replacement phone. I have tons of Macs, iPads, iPhones, etc (for both myself and my wife) and I've never seen Apple so reluctant to do a hardware swapout as they were when I was in the store yesterday.

Did you transfer the backup for your 3GS to your iPhone 4S?
Try a reset, which is done by pressing and holding the home button and the sleep/wake or on/off button simultaneously until you see the Apple logo and then release.
If no change after a reset and you transferred the backup for your 3GS to your 4S, try restoring your 4S with iTunes as a new iPhone or not from a backup to see if this makes any difference.

My 3GS gets very hot and battery drains from 100% to 0% in less than few hours

The problem is really tricky. I kept tracking the problem, the problem persists only in the following case, if cellular data is on with no dataplan registered.If dataplan is activated the problem disappears

I forgot to add, I closed notification center, all push and pull activities and ping.

ThinkPad E455 Excessive Battery Drains When Power Off

I bought a new ThinkPad E455 two months ago with AMD processor and I use Windows 7 (64-bit) as my operating system. The problem is, since a week ago, when I turn off my laptop (completely shut-down, not hibernating nor sleeping), the battery looses 14% in less than 24 hours. This problem has never happened before. When I search for solution, apparently my problem is similar to https://forums.lenovo.com/t5/11e-Windows-E-and-Edge-series/E535-High-battery-drain-when-laptop-is-powered-off/ta-p/1249897 and https://forums.lenovo.com/t5/11e-Windows-E-and-Edge-series/E530-Battery-drains-and-power-manager-issue/ta-p/1249887 and https://forums.lenovo.com/t5/11e-Windows-E-and-Edge-series/E440-battery-drains-when-powered-off/m-p/1527086/highlight/true#M18743. It appears that the power drains happened in other type of ThinkPad as well. Moreover, it seems that this problem is not limited to ThinkPad series (e.g: http://www.tomsguide.com/answers/id-2324931/laptop-battery-drains-powered-shutdown.html), and more surprisingly, some of other brands experience this condition as well. My question is, what causes the power drain? I mean, the laptop just worked fine for a period of time (in my case it is two months), if it was trigerred by something, what is it? I looked for the technical updating BIOS solution in http://support.lenovo.com/us/en/documents/ht077068, but unfortunately the series E455 is not in the list. Of course, updating the BIOS using incompatible version is not recommended by the technical support. Please help me.

See https://en.wikipedia.org/wiki/Advanced_Configuration_and_Power_Interface When you think the laptop is powered off it's actually in ACPI Power State S5 with power being supplied to the power button and some of the USB sockets. So, when you shut down the laptop and then removed the power cord, if the BIOS version was lower than 1.13, the laptop was still draining the battery.I followed your suggestion, and it seems solving the problem, thank you. However, another problem arises just recently. When I was playing a game on my laptop, the battery capacity is decreasing when the AC power connected (as described by both lenovo and Windows battery gauge). I post this problem in https://forums.lenovo.com/t5/11e-Windows-E-and-Edge-series/ThinkPad-E455-Battery-Capacity-Reduced-When-Connected-to-AC/td-p/2106218. Oddly, the problem (seems) does not occur when I quit the game to windows. Why was this happen?

Lenovo notebook E540 Battery drains when it is not powered on

Lenovo Notebook E540 battery drains when it is not powered on. My colleague said that there is a cloud connection being connected during power off and it consumes power. Is that possible? Any resolution?

Hi Kingchechan,
Welcome to Lenovo Community!
As far as I know only the Windows update will be accessing to the server, or might be any other 3rd party cloud related application, which might be accessing to the cloud server.
Did you check disabling USB always on in BIOS & Wake On Lan from Windows AND BIOS
Check running command powercfg /devicequery wake_armed to see if any device is programmed to power on the laptop might be this is consuming battery power.
Best regards,
Hemanth Kumar

Battery Drain when not in use--Gen 6 Nano

I have used Ipods for years now. Still have an Ipod Classic and a Shuffle that I use regularly. I have been pleased with the battery life, as a whole.
Recently I purchased a Nano Touch--Gen 6. I really like the Ipod + Nike features.
The issue I have is with the battery draining when the unit is not in use. If the unit has been fully charged, I will unplug from computer or wall charger and make sure that: 1)Music/radio is paused 2) Nike receiver is unplugged from Nano. 3) Screen is off.
If I do not use the nano for an extended period of time, say around 12-18 hours, I notice that the battery has drained between 50%-75% even if nothing is playing or "on". Nothing should be draining the battery this far, in my opinion.
I can't believe that this is typical. Do I have a bad battery?
Your help would be appreciated.

You are not alone. I have had my Nano for several weeks now and have noticed the same thing. I would use it for short trips in the car while I ran errands and find that after only technically using it for maybe an hour or so (over the course of several days), I would already be low on battery. I read the manual and you can only put the ipod in sleep mode. It stays on for 36 hours and only then will it actually turn all the way off. So technically the battery last for several days but that doesn't do you any good unless you are using it for long periods of time all at once. I'm really frustrated because I really like it other than the fact that I'm always having to charge it.

IPhone4 battery draining when not in use

am just wondering if anyone experiencing battery draining when not in use? i charge my iphone4 before going to bed and woke up this morning to realise that my battery had drain 22% on stand by... is this normal? can anyone confirm it to me please, thank you

Just an update guys --after draining (on standby) over 20% of my battery charge last week, it has risen to or about 40+% in the last couple of days. I haven't changed any settings or whatsoever. I had to charged it twice during the day yesterday and it was bloody frustrating. anyway, i went to the apple shop today and told them the problem... they scanned my iphone4's battery and it was evident and showed when was the last time it was charged and how much battery life has it lost throughout the day. After scanning my iphone we did not even have to discuss repair or do any setting or software checks. I was gobsmacked --as i did not have to ask for a replacement, I was immediately offered a swap to a brand new iPhone4... lucky me? umm, i don't know...maybe? But the thing is, they seemed to be aware of the problem and they are keeping a low profile on tackling the problem. so my suggestion is if anyone has a battery problem with their unit, take it to apple and have the battery scan. As such, i have to wait and see if this new unit will present the same problem, although i must admit, for some reason, this new unit has a slight different behaviour than my previous iphone4.
Other issues on my previous iPhone4:
1. frequently dropping signal --not a problem with the new replacement unit
2. if i turn off my "phone" feature on the multitasking bar, red dot appears on the phone icon and i couldn't make a call as it seemed blocked and it kept asking me to set-up the voicemail feature every time --again, not a problem with the new unit.
3. even my tomtom app has changed its behaviour, i have discovered new features without updating the app --strange isn't it?
4. playing NOVA game was a pain with the previous unit as i kept getting network problem and interrupting the game.
5. it kept shuffling my music when i'm using ipod whilst walking. imagine, hearing about 8 different tunes in a span of 5 seconds...
anyway, time will tell with this new unit as i have kept the same settings from my previous unit and uploaded my previous back-up data and apps. so it would be like having my old iphone4 and we'll see in the morning if it will drain on stand by as well --i hope not 'cos am getting really frustrated with it. oh, by the way, blue tooth feature don't work with my new replacement unit --NICE!!!

Battery drains when power connected

Hi,
Early 2011 MBP 17inch battery drains when the power is connected. It seems to be that when the system is having some load battery is discharging even when the power is connected. Is this normal?
Regards

Yes it is normal, For Mac's that is. Apple doesn't supply a large enough AC power supply to both charge the battery, or stop it from being used, when the system is under heavy load. Once you start to run the system hard it will draw power from both the AC and the battery.

IPad mini with retina very slow and battery drains fast

my ipad mini 2 is only ten months old. After getting the iOS 8 currently on ios8.0.2, wifi internet speed is only 25% of the normal speed (compared to what my imac tested), battery drains 1% every 3 minutes or so. All of these after I restored it to factory setting per Apple support suggestion. is there any fix for this soon? why is the issue only affecting some but not all users? Is there anything I can do for my ipad? I have only been using it lighty (have installed like less than ten app's) but this is still very frustrating.

iPad running slow? How to speed up a slow iPad

If You Think iOS 7 Feels Slow Here’s How to Speed It Up
http://osxdaily.com/2013/09/23/ios-7-slow-speed-it-up/
You may have many apps open which can possibly cause the slowdown and possibly the loss of wifi. In iOS 4-6 double tap your Home button & at the bottom of the screen you will see the icons of all open apps. Close those you are not using by pressing on an icon until all icons wiggle - then tap the minus sign. For iOS 7 users, there’s an easy way to see which apps are open in order to close them. By double-tapping the home button on your iPhone or iPad, the new multitasking feature in iOS 7 shows full page previews of all your open apps. Simply scroll horizontally to see all your apps, and close the apps with a simple flick towards the top of the screen.

Battery drain when not in use

Occasionally, the battery in my 3rd generation iPad rins down to near nothing in a very short time, even though I am not using it. The Ipad has not been turned off, but there are no apps open. The WiFi is on, but cell data turned off. Sometimes, when I have set it down for a few hours, I'll pick it up and it is particularly warm and the battery is near dead. Other times, it seems to hold a charge for several days. When I am using it, the battery drain seems to be normal. Is there something under the hood, as it were, that I am missing? Is there something I have left running that isn't apparent?
Thanks,

Look in the notifications. there's a ton defaulted to on that you may not need.
Also look to background app update and background app refresh. those also run in the background and can effect your battery.
You may also want to shut down any programs/apps that are running that you may not need. Double tape the home button. You'll see the previews for all running apps on the screen. Flick the preview up and off the screen to close the app. Tap on the home screen preview or single tap the home button to exit the mode.

Macbook Pro running slow/battery drains when closed

Hi!
I have a Macbook Pro 13-inch, mid-2012 running OS X 10.9. It recently started running extremley slow and the spinning ball pops up all the time when I try to do basically anything, but mostly when I try to do more than one thing at a time. Sometimes it will run normal, but then slow up. The spinning ball also pops up basically everytime that I try to play a video or anything like that. The adobe flash plugin also seems to crash a lot.
Also, when it is closed, it becomes very warm and the battery drains while it is closed. It seems like it doesn't really turn off when it closes.
Anyone know what could be causing this?
Thanks!

I ended up having to take it in. Turned out there was a connection to the hard drive that was loose or something. I took it to a store in my city that specializes in macs so I didn't have to spend a fortune. Otherwise, I had someone else look at it and they said that it could have been from when I updated my computer, that something didn't download properly- which has been an issue in some computers.

Camera battery drain when shooting tethered to LR3.x

Hi:
I've been experiencing very rapid battery drain in my Nikon D90 when shooting tethered into a laptop running LR3.x under Windows7 32-bit. Is this to be expected because of the constant transfer of images across the USB connection?
Thanks in advance for any insight on this.
Regards,
Peter

Even transfering via USB for downloading will cause the battery to drain. Tethering would certainly drain the battery more than shooting non tethered, but it shouldn't feel excessive.

N95 Battery drains when plugged into PC

When I'm working I have my N95 plugged into my PC but, I have found that my battery drains quicker than when it's not connected to the pc.
Can anyone explain why this is or, do I have a problem with my N95?
Regards,
Jono

Isn't it also accessing the external drive as well, thus taking CPU cycles, thus draining the battery? As the USB does not charge but provides signaling from the phone to the PC via the USB it would be safe to assume that the power drain is simply from the constant communication.
Show the KUDOS button some love.... Hit that bad boy.... It don't hurt....
