How long is the iPad battery last while watching video on YouTube with 3G?

How long is the iPad2 battery last while watching video on YouTube with 3G?

My iPad 2 battery can use only ~7 hours 15mins when surfing the web using cellular data network. Is it normal?
I would say that's normal. Cellular uses more power than wifi. Your screen brightness is also a factor. Lower the screen brightness & battery will last longer.
The quickest way (and really the only way) to charge your iPad is with the included 10W USB Power Adapter. iPad will also charge, although more slowly, when attached to a computer with a high-power USB port (many recent Mac computers) or with an iPhone Power Adapter (5W). When attached to a computer via a standard USB port (most PCs or older Mac computers) iPad will charge very slowly (but iPad indicates not charging). Make sure your computer is on while charging iPad via USB. If iPad is connected to a computer that’s turned off or is in sleep or standby mode, the iPad battery will continue to drain.
Apple recommends that once a month you let the iPad fully discharge & then recharge to 100%.
At this link http://www.tomshardware.com/reviews/galaxy-tab-android-tablet,3014-11.html , tests show that the iPad 2 battery (25 watt-hours) will charge to 90% in 3 hours 1 minute. It will charge to 100% in 4 hours 2 minutes. The new iPad has a larger capacity battery (42 watt-hours), so using the 10W charger will obviously take longer. If you are using your iPad while charging, it will take even longer. It's best to turn your new iPad OFF and charge over night. Also look at The iPad's charging challenge explained http://www.macworld.com/article/1150356/ipadcharging.html
Also, if you have a 3rd generation iPad, look at Apple: iPad Battery Nothing to Get Charged Up About

How long does the IPhone5c battery last for without hardly any usage with about 2/3 to 3/4 left?

How long does the IPhone5c battery last for without hardly any usage with about 2/3 to 3/4 left?
Has the side affect of charging, where the battery's life gradually decreases overall with each charge, been fixed ?

Eric,
They did say 12-14 hours, but as is always the case with such estimates, they invariably quote the 'best possible scenario' and almost never mirror 'real world' conditions.
If, from a fully charged position, you simply switch on your nano, and set it to continuously play through a long set of songs, with EQ off, backlight off, modest volume (50%) don't touch it during playback, then you might just get somewhere near this figure - and if you don't then it's either not been conditioned properly or it's faulty.
If you use it like me, daily for a couple of hours, with 2 secs backlight and switch songs regularly, using fairly high volumes then 6-8 hours is more likely. It'll even drain when it's not in use, even in sleep mode, albeit very slowly. They also tend to drain more quickly before they've been through their first few charge cycles (the conditioning period).
Personally I haven't got a problem with this though I can understand why some people have. It's not very impressive in this respect. Apple should be able to come up with something much better - maybe they should talk to Sony

I don't know that Apple has published that information, but my guess is about five years under normal usage.

How long does the MBR Battery last in years? Deciding factor on purchasing? Help?

I'm nearly ready to pull the trigger and get my first MBR 15 inch, but something keeps nagging. The Battery. THE BATTERY. Yes the battery is relatively nice, and one might think insignificant in the grand scheme, but IT'S GLUED INSIDE THE COMPUTER, and basically IRREPLACEABLE unless you pay some ridiculous cost, my guess is around $400. So how long is the battery expected to last? 4 years? No battery lasts 4 years. It's mind-boggling to me why Apple decided to glue the battery. After 2 years of moderate to heavy use of your MBR you're just expected to fork over $400 for a new battery? A NEW BATTERY?!!!!! Realistically how long will the MBR battery last before it gives up the ghost and has to be plugged in 24/7?

It is not "glued" inside the computer. And yes Apple offers a replacement program for $200 and under depending on the model for out of warranty:

How long should the MBP battery last?

HI, I have had my MBP 17inch for a few months now and its seems that the battery is rubbish! I generally get about 2-2.5 hours out of it, even when just surfing the internet. I calibrate it regularly, dim the brightness, turn off aiport etc.
Its says on the webiste I should get 5.75 hours! How long does other people's last? I was wondering if it had anything to do that I have the Hi Res version 1920-by-1200. Would it use more power?
Thanks very much for any info.
Ian

Use the iStat widget, not CoconutBattery. FYI, the "real" values should be checked in Utilites > System Profiler > Power.
Your "original capacity" is 6300 mAh. That's a nominal value, which is why yours is actually higher - new batteries range from 6200 - 6700 mAh, approximately. The 5500 mAh is the correct value for the 15" MBP - CoconutBattery can't tell the difference.
Be sure to properly calibrate your battery every couple of months.
RE your original post, 2.5-3.5 hours of battery life is normal, depending mostly on screen brightness.
Hope this helps...

HT4060 How long should an iPad battery last?

When using my iPad continually I only seem to get approx 4 hrs use, is this about right?

The usefull life of an iPad battery is about 1000 full discharge/charge cycles, by Apple's standards (i.e. at 1000 cycles, if not abused, it should retain about 80% of its original capacity). But, a Lithium cell begins to loose capacity from the minute it is assembled at the factory. It will continue to loose capacity over time, whether used or not. So, if your iPad is a couple of years old and has had a lot of use (that is many discharge/charge cycles) then it will inherently last less and less on a charge as time goes by. Also, if it has sat unused for very long periods (several or many months) it will have degraded much faster than if used regularly.
As others have said, it also depends on your settings, and just what apps and things you normally run on it.

That listed 7 hours is with very limited use. Low screen brightness, low keyboard backlight, No WiFi or bluetooth.
Most I have ever gotten from my 15" 2011 model is around 5-6 hours and that was with very light use. Just Web, Chrome, and email, thunderbird, and Wifi.

How long does the buttery normally lasts on Equium U400-145

Hi guys,
First of all I can't find the EQUIUM U400-145 in this website and secondly I would like to ask how long does the buttery normally lasts.
Thanks

Sorry but I can find it there. I am asking what you are doing wrong. It is so easy. There is just one Equium U400 available. It is PSU42E and it is exact your model.
Please check it again.

How long does the battery last on a full charge

Hi Jason,
The iPod nano (3rd Generation) has a battery life of 24 hours of music playback and 5 hours of video playback. This will deteriorate over time as the battery becomes consumed. Total charge time should be around 3 hours.

How long does the internal battery usually last?

I keep seeing posts about the date going back to 1969 so I'm wondering what timeframe am I looking at to replace the "watch" battery. I bought my PB back in '04. Thanks.

Until recently, I thought the PB backup batteries simply ran down. While visiting the Apple Store in Portland OR a couple of weeks ago, I mentioned this to one of the techs and he said the PB battery was rechargeable like the ones in the older G3 PowerBooks.
I was given a 2003-vintage PB17 recently that had been in storage (off power) for about six months. The backup would not support the time needed to change from battery to corded operation when running down the main battery. After having the PB on wall power for several weeks, I tried it again and the backup battery was able to allow the power switchover without the computer shutting down completely.
Based on a sample size of n=1, the backup could be rechargeable. My big grip is that the batteries are hard to find and darned expensive. Too many offered online are sold as "used." If it's not rechargeable, what's the point of a used battery?
Even rechargeable batteries have a finite lifespan so, if shopping for one online, get assurances that it is not used. I still have concerns about "new" batteries like this. If Apple has not made new parts recently, then those from inventory could be almost as old as the one you're replacing.

How long does everyone elses battery last?

I took my powerbook to my local apple store because I thought something might be wrong with it. They told me nothing was wrong with it. I know apple says it will run about 5 hours. The "genius" told me that is only true if you are not using ANY programs. I find this a strange thing because by that standard if I'm not using any programs i can tun it off, in which case the battery lasts forever.
I just did an experiment, becuase I am about to leave the country and have many long flights over the month of January, during which, I would like to watch DVD's.
On a full battery my Powerbook played a DVD for 27 minutes before it lost power and went to sleep. It seems to me a computer that will only read a DVD for 27 minutes...well...*****.
It also may be relevant that my super drive is one of the newer ones that can burn DVD-R DL discs. My airport card was on, but no other programs running and the bluetooth was turned off.
Should my battery last longer than 27 minutes while watching a dvd?

No, you should probably get close to 2 hours. See all the other various threads about battery life with new powerbook, and you see how to check your battery capacity and see if you need a replacement.
This has been covered in great detail.

How long does the free service last?

I am unclear as to how long my free CS Review account will be available? Can you clarify. Also, will my account be canceled afer a trial period and will my files all be deleted? It was hard to find this info in the documentation.
Thanks for your help.

Hey Kevin,
I work with Adobe and can help answer your questions for you. The complimentary subscription lasts for 12 months from the day you sign up, as long as you are registered before 4/30/2011. Regarding your second question...your files will be saved indefinitely and available to you even if your CS Live subscription lapses. All you need to do is login to www.acrobat.com to access them in your personal organizer that is available as part of the free account. You can also have full access to old reviews, including the ability to comment and share. Once the complimentary trial is over you can then register for a CS Live subscription which will give you the ability to continue creating new reviews and grant you access to the entire CS Review panel. I hope this helps out. If you have any more questions feel free to ask!
Andrew

How long does the trial version last? What happens when it expires?

I currently have a trial version of Photoshop CC. I do not know how long the version lasts, nor do I know what my options are when it expires. I would appreciate your answering these questions. I probably didn't read the fine print!
Judy P

Each time you open a trial version Adobe normally presents you with a countdown screen showing you precisely how many days of your trial are remaining with buttons asking you to sign up or buy the software.
Do you see that screen when you launch the trial version?

HT4796 How long should the migration process last?

I am trying to do a migration from my PC to my new Mac. How long should this process take? Mine has been running for at least six hours now and still has not completed. Is this normal?

Welcome to Apple Support Communities
It depends on the amount of files you are transferring and the method you are using to transfer your files (Wi-Fi or Ethernet). Both methods are slow and migration would take hours if you need to transfer a lot of files.
I only recommend you to use Windows Migration Assistant if you need to transfer a small amount of files. If not, it is much better to copy your files to an external drive and transfer them to your Mac
