How long should the battery life live?

My Itouch keeps dying after only 3 hours!

It depends on what you use it for. If I am listening to audiobooks, my iPod touch will go for hours. If I am using it for email or other internet type stuff it will last a few hours, but I have a few games I play (Boggle for example) which have 3D animations. I asked your question shortly after getting the game. It uses a lot of battery power and in an hour or so of a lot of playing it needs recharging.

How long should the battery last while surfing the web?

I'm curious to know how long the battery on my Macbook should last when just surfing the web and downloading music and videos. I'm getting about 3 hours, I have a feeling it should be a lot longer. I don't have the brightness all the way up and I dim the illuminated keys.

It really depends on your configuration and what you are doing on the web.
If you have minimum RAM, the HDD will be accessed more often, causing heat which causes the fan to come on more often, which uses up power.
While I watch youtube and other forms of streaming video, my fans are usually on, so my battery life is less.
While cruising these boards and such, my battery lasts twice as long as streaming.
3 hrs while downloading music and videos is not a bad figure.
What you might want to do is watch a 2 hour movie and document the amount of time you get from the battery.
Do the same while streaming a movie.
Do some typing and or general surfing sans streaming type stuff.
The above spans a different range of CPU and graphics usage.
Then post back your times here. You will get a better indication of battery condition.
Also, post back with how much RAM you have.

How long should the battery last in between uses?

I am just wondering how long the battery should last in between uses? I find mine really goes down FAST..I just purchased this on Sunday and charged it the right amount of time as such. The first time I used it after the initial charge I was downloading 2 music albums and just left it on and by morning the battery was drained..shouldn't it have lasted at least a few days? Its an iPod touch 16g V2.
Then lastnight I had it charged and was browing youtube and in a couple hours the battery was about 1/2 way..is this normal?
Thanks for your help!

The Touch's Wireless Internet access really chews up the battery time. When you're not using the wireless, go to Settings and turn Wireless off. When you're ready to go browsing, you can always turn it back on. If you already have a wireless access set up in your abode, the Touch will quickly "re-find" it and you'll be browsing again. If you're in a public free wireless area, you'll have to log on, etc.
If I leave wireless on all the time, my iPod Touch battery life is like halved-- sometimes more. The same holds true when viewing movies or video.
Hope this helps!

How long should the battery last?

Hello:
I have a MacBook Pro from february 2007. The battery (which Apple had to replace while under warranty), lasts for about 2:30 to 3 hours, depending on what I am doing. Is that normal? What is the expected/theoretical time it should last before completely dischanging?
Thanks

That's pretty normal, yes, and nothing to be concerned about.
You can check the "health" of your battery in System Profiler - look at the numbers for Full Charge Capacity and Cycle Count. Health is the percent of the original (new battery) capacity, which is 5500 mAh for a 15" MBP, and 6300 mAh for a 17" MBP, i.e. (current Full charge capacity / 5500 or 6300 * 100). Apple spec is 80% health for 300 cycles. Li-based batteries like the one in your MBP have a useful life of 400-500 charge cycles or 3-4 years, whichever comes first.
Hope this helps...

How long should the battery realistically last?

i bought a 13'' macbook pro about three weeks ago. the battery is supposed to last about 7 hours (depending on usage and the such) but i feel that it isnt lasting more than three, and thats with only web surfing. is there a solution to help it last longer? and i also tend to leave my laptop plugged in, sometimes for hours after its fully charged. is this a bad thing?

you can leave your macbook plugged in all the time if you wish. it will not harm your battery since it will stop charging once it's fully charged.
once in a while however, do use your macbook under it's own power and plug it back in when it's down to 80% to keep the battery in optimal condition.
now, disable your automatic brightness. turn off your bluetooth if you're not using it. turn off yourr remote control receiver if you're not using a remote.
check your login items to see what's loading at startup and delete them if you don't need it.
see what's using up most of your cpu's resources in activity monitor - all processes. highlight the ones using the highest % CPU and hit quit process.
see if the above tips give's you at least 5 hours of battery life.
if you feel that your battery isn't lasting long after you've done the above, you can always take it back to apple and have them check your battery or have it replaced since you're under warranty.
good luck..

MacBook Pro-How long should the battery last?

Hi there i just recently got a MacBook Pro a month ago this is my first laptop and i was wondering how long the batery is ment to last for befroe going flat? my macbook is the most recent 13 inch one and its battery only tends to last 6 or 7 hours before i need to charge it again, just wondering if this is normal?

I have the same MacBook Pro, and "eww" is absolutely right. 6-7 hours is what you will get under normal use. Now if you want to see the battery reach 10 hours, dim the screen to 6% and just do nothing. Just kidding, but you get the point.

How long is the battery life?

Just curious

If you mean a fully charged iPod Classic battery, when new, it is about 40 continuous hours of music or about 6 hours of video.
However, it has a shelf life of about 400 recharge cycles, which mean if you recharge once a week, it will last about 6-8 years, although it is not linear, as the capacity is reduced over every recharge, and you may have to recharge more than once a week.
Most iPod after the first year, has about 30 hours of continuous music, and about 4-5 hours of video.
Have a nice day!

How long should the battery in an iPhone 3GS last?

I have had my 3GS for exactly 1 1/2 years and all of a sudden my iPhone is going from 100% to 90% after unplugging from my iMac at 8am and answering one short phone call in the morning it is 90% two hours later. I had to recharge it after being on for 7 hours with about 10 - 15 min of phone use and the low battery warning came on at 10% and I connected it back to the iMac at 7%. Must have missed the 20% warning. Left the house without it because I had to take it off my person to do a 3pm recharge. TERRIBLE, TERRIBLE, TERRIBLE!
Not pointing a finger but I upgraded my iMac to Lion and I had to update iPhone to 5.0 and that was when I started having problems.
What gives

Problem with ios5. Update will hopefully be out soon

How to increase the battery life of your N series ...

What I am about to post here is valid for any 3G phone or device regardless of model but it is particularly focused towards the N series devices and their power hogging features.
Your battery life is dependant on many many things. How often you take calls on the device, the condition of your battery, the features you use on the device and so on and on. Therefore it is impossible to say that by following the information in this post you will get x amount of days battery life, but it will get you more time out of the battery than you otherwise would have got.
So with that out the way, if your looking to increase your battery life then follow these tips and your battery should start looking a lot healthier.
First of all lets start with THE big one. The one that is going to save you the most juice. Switching 3G off.
Yep, you heard me right. Just by switching the 3G capability of your phone off you will add hours and hours to your battery life. How is this so? Allow me to explain...
Due to the rather poor delivery of 3G in the UK by the network operators, it is rare for any 3G phone to maintain a constant 3G signal. Instead you will find that the phone constantly flips between 3G and GSM mode (Keep an eye on your signal one day). Even those of you on Vodafone who probably have the best 3G network coverage will find this is the case.
Unfortunately, this constant flipping between the two modes sucks power from the battery like a vampire as it alters its reception state for the different modes and the constant flipping is..well...causing it do this constantly! It can sometimes even make your phone unavailable for calls for very brief periods as it trips from GSM to 3G and vice versa.
If you need to use 3G for video calls or whatever then I'm afraid your just going to have to live with this but if you don't (And lets face it few of us do) then you can switch 3G off and increase your battery life considerably.
To do this, go into the "Settings" application (Found in the menu somewhere, by default Nokia normally stick it in "Tools"), and then to the "Phone" tab. In there you will see an option that says "Network mode" and you have a choice of "GSM" or "Dual Mode" (I.e. UMTS and GSM). Set it to GSM and your phone will restart. Once it restarts it will be working in GSM with GPRS speeds only but really for most purposes this is fine.
You have now just extended your battery capability considerably. You can further extend it by going to the "Connection" tab, going into "Packet data" and changing it to "When needed" so it is not constantly checking for a data connection.
The second big change you can make is to turn your phones wifi scanning capability off. The last time I looked not all Nokia's phones that have wifi capability can have their wifi cards switched off entirely but if you can, turn it off except for when you need to use it. Wifi is a power hog.
The next big change you can make is to lower the screen brightness settings on your phone. The less bright your screen is the less power is being used to light it up. Nokia by default leave the screen brightness at something like 50%. Lowering this a bit more will conserve more juice. Before you do this though please consider the fact that lowering the brightness setting will have a big impact on your ability to see the screen clearly in sunny conditions although you will be fine in the dark as you can't lower the brightness that far.
To lower the brightness, go to the settings tool in your phone and into the display option (Hidden in a subcategory called "Personalisation" on the N95). It won't hurt to set the power saving time out to 1 minute and the backlight time out to 10 seconds while your here (Although these are the Nokia default so they should already be set to this).
Finally in regards to the screen, although they may look pretty, animated screensavers use more battery power than the standard blank screen with time and date so avoid them if you can.
It also helps to keep Bluetooth switched off until you need it although the power savings are minimal in comparison to the other changes but every little milliamp counts!
Using the above methods I generally get about 3 to 4 days with about 3 hours talktime on my N95 without using Bluetooth, GPS or anything like that (I might be able to get more but so far I have not paid attention to the battery state before I put it on charge). If I am on a long train journey I can get about 4 hours worth of full screen video and about 2 hours talktime over the period of about 24 hours before it needs a recharge. As I said at the start of the post your mileage will vary greatly depending on how you use your device.
Hope this helps.

no keffa it is a cop out from nokia

the n95 battery is atrocious
dont change the post content as the title is 'How to increase the battery life of your N series device'
your talking about nokia phones specifically
the networks are not to blame
they do not make the handsets : Nokia do !!!!!!!!!!
I'm going to choose my words carefully here...
I would never deny the battery on the N95 is not really up to the job of powering the N95 with its power hungry features. To put the same battery into a phone that has WiFi, GPS and a large 320x240 screen, the same one that goes into the E65 which has comparatively nothing compared to it is a bit pants.
However at no point was I criticising them for the band hopping problem. I labelled the post as how to increase the battery life of your N series device because this is a board for the N series devices. It was a simple choice of wording and not intended to be cutting in any way and I did make a remark that the details would be true of any 3G device at the top of the post.
What I was trying to point out in my second post is that the constant band hopping the phone is being forced to do that is draining its battery so much more quicker than it would if it had a constant signal of one kind or another isn't quite Nokia's fault.
They build it to conform to a laid out specification for 3G. However if the network operators cannot be bothered to roll out their 3G infrastructure adequately enough that the phone can find and remain locked onto a 3G signal that is usable then what are Nokia to do other than offer you the capability to turn 3G off until you need it (Although note to Nokia: That **bleep** reboot the phone does when you do this is entirely unneeded and you know it).
Blaming Nokia for this would be like blaming the manufacturer of your radio for failing to pick up radio because the radio station does not have any transmitters within range of your radio's receiver.
Finally...this band hopping is exhibited by all 3G phones built by Samsung, Nokia, Sony Ericsson, etc, from their most budget 3G model to their priciest piece and is the reason that all phones with 3G capabilities have batteries that do not last for any respectable length of time because these phones are also having to band hop between 3G and GSM.
Finally the proof is in the pudding. Turn 3G off for a few days. See your battery improve. Then (Although admittedly this will be harder to do...mcuh harder) find an area where you get a fairly decent 3G signal constantly. Again, see your battery improve. Try it with a different 3G phone...different manufacturer even. The same will be true.
So I stand by my comment, the network operators and their woeful 3G rollout are the villains costing you a fair chunk of your battery and Nokia cannot be expected to mitigate this....but a better battery would be nice all the same...

How long should the Mac Book pro hold its charge???

How long should the Mac Book pro hold a battery charge??

For a single use or how long will the battery last until it needs to be replaced? For single use, it depends on what you are doing when using you mac. I find that when using mine I get about 6-6 1/2 hours just using it to browse the internet before I need to recharge it. If it is one of the newer Macbook Pros that claim to have a 7 hour battery life, It can last up to 5 years. See this article on notebook batteries to get the most out of your battery: http://www.apple.com/batteries/notebooks.html. Hope this helps

How long is normal battery life for late 2011 macbook air?

How long is normal battery life for late 2011 macbook air?

I would also note that the 11" and 13" have different lives. While the 11" has a smaller screen to drive (and thus, in theory, less power) it also has less space for a battery. So it turns out the 13" has a longer battery life, all other things being equal (same usage and the like).
Clearly what's "average" will vary by user. Depending on what I'm doing, I can get Apple's rated life (or darned close) or I could end up well short of that life. The "rated" life is 5 hours for the 11" and 7 hours for the 13" but that is, at best, a very rough approximation. As the picture in captfred's response makes clear, the actual usage of the machine has a huge influence.

How long should my battery last on my ipod classic

how long should my battery last on my ipod classic?

Depends on its age, settings that in use on the device, what it is being used for, and whether or not it is being charged up to 100% each time (usually takes a minimum of about 4 hours or so).
According to Apple tech specs for the current iPod Classic you should be able to get 36 hours of audio playback on a full charge or up to 6 hours of video.

HT4623 Hi!My iPAD lost its charge fast !!I've got an iPAD capacity 57,1GB and it has available 55,1GB ,version 7.0.4 .I'd like to know how long does the battery last when it is 100 % charged.

Hi!I've just installed the iOS 7.0.4 operating system and the battery lost its charge at an incredibly speed.I'd like to know how long does the battery last if everything is right when it has 100% charge.Thanks!

I`m `propping` up this thread to to the top of the forums again as it`s been three months and not a single community member or Apple support personnel have replied, which I find discouraging.
I`ve tried everything - both the iOS device(s) and Apple TV have been upgraded (albeit reluctantly) to the latest versions, since iOS 7 looks like crap compared to iOS 6. Both use the same WiFi network. Bluetooth is set to `off`, as per the online tutorials on the Apple Support page.
I also tried shutting all of them down, including the router, waiting 30 seconds and turning the router, then the Apple TV then the iOS device on sequentially with 30 seconds in between each, again as per this discussion forum, and still nothing.
Why can Apple not make a technology, such as AirPlay, work with greater than 10%?
Any other ideas?
Come on, people.
Thanks,
Doug

HT5262 How long should the icloud back up take?

How long should the iCloud back up take? I only have 4gb of storage but it has taken almost an hour already with approximately 2 hours remaining.

Hi RMaskery14,
If you are concerned about the time your iCloud backup is taking, you may find the following article helpful:
My backup is taking a long time to finish.
Backing up and restoring takes time, especially if you have a lot of data or a slow connection. Depending on the size of your backup and the speed of your network, you may need more time than expected to complete the process. Using a reliable connection when backing up your device is highly recommended.

How long would the battery last if you were usinng it for wireless msn around the house..
Thanks,
Andrew

I never get less than 3 1/2 hours and generally get a bit over 4 hours on a fully charged battery. Before unplugging I make sure BlueTooth and sound is off, the backlight is set as low as I can stand it, I have no disc in the drive, and all the applications and files I intend to use are running and loaded. The three biggest juice eaters are the display's backlight, the hard drive and optical drive so I minimize the use of all three while unplugged.
Are Mac notebooks tough? A couple quick stories: I dropped my G3 iBook off my desk and it hit the concrete floor on its corner breaking off a large piece of plastic. I fashioned a fiberglass bandage and used the computer for 3 months before finding a functional used shell. A customer came in with a horrifically bent PowerBook last summer - it fell out of his motorcycle sidebag while he was driving (35 MPH) and was run over by at least 1 car. It booted up and the display while bent by the mangled case still worked. I actually used Migration Assistent to move his stuff to the new computer. A student brought me his MacBook which he'd dropped down half a flight of stairs at the college. It had been in a lightly padded sleeve. It looked banged up - there were some fractures to the bottom case and the hinge squealed terribly as I opened it. But the computer woke up and it checked out okay. AppleCare basically replaced everything but the innards - the guy's home insurance covered all but the deductible which was a good thing - that is an expensive repair! Would the typical PC survive these accidents? Well, I know from experience the cheap plastic Dell and HP models wouldn't.
