MB battery life playing DVD's

I am travelling with the kids on a five hour flight next week. I don't want to bring the portable DVD player if I don't have to. Assuming I charge my relatively new MB completely before the trip, how long can I expect the battery to last if the kids are watching a DVD with all other applications turned off. Can it last an entire DVD? Two? Thanks

It would depend on the length of the movies. A better baby sitter would be maybe 1/2 hour or 1 hour different shows. Pirates of the Caribbean is 2.5 hours. Expect around 3 hours. You might want to check seat guru ( http://www.seatguru.com/ ) as they usually have information on whether your seat has a power port (which won't charge but over-ride the battery during play). If you're still not sure, call the airline itself and ask...perhaps a move of one or two rows will work...oh yes...and bring cards and a paper book besides your MacBook for them.

What is battery life playing DVD's on 13" macbook Air?

What is battery life playing DVD's on 13" macbook Air?

Trick question. The MBair doesn't have a DVD drive so depends on how much power your external drive draws.
If you're playing movies in iTunes then it lasts longer. Also depends on which model (year) MBair. Here's Apple's statement on the current (2011) line.
"Since space-saving flash storage leaves room for a bigger battery, you can devote more time to the things you enjoy most. Things like browsing the web, editing photos, and watching videos. Get up to 5 hours of battery life on a single charge on the 11-inch model and up to 7 hours on the 13-inch model. Put MacBook Air to sleep, and it enters standby mode to conserve battery life for up to 30 days.3 When you come back to your MacBook Air and open it up, it’s on in an instant."

Battery life of iPod touch 4g whilst playing 3d games

I recently bought an iPod touch 4th gen and one of the first apps i downloaded was Modern Combat 2. I noticed that after only playing for a few minutes, my battery had begun to be used up pretty fast. I downloaded Magic Battery and it says my device is only good for around 2 hours of 3d gameplay. And whilst playing MC2 i found out that 7 minutes of it would drain 20 % of my battery.
Before i download other games such as NOVA 2 or Dungeon Hunter 2 which are both 3d, i'm asking: is this normal? Is power usage on these games THAT dear or is my purchase faulty and should i return it?
Note: when i played MC2, i was not multitasking, brightness =0%, and all measures to prolong battery life were in place.

5 hours is definitely too quick for a battery discharge. Try a few of the solutions here http:

but if it does not hold a charge longer then take it back to the Apple store and ask for an exchange or a refund.

Does playing heavy-graphic games on iphone 5 until it's hot reduce the battery life?? plz answer :)

so yea , does doing that gradually damage the battery of the iphone 5 and overtime curtail the battery life and lifespan?? I play fifa 13 on my iphone 5 for lengthened periods until I can feel it get hot almost every day. Is doing that actually harmful to the iphone battery and its lifespan?? im curious becuz before I've seen on the apple battery care web page that heat is the factor that will degrade battery performance the fastest on idevices, so Im just afraid concerned. plz answer

Batteries have an expected number of charge cycles before they degrade and you begin to experience diminished battery life. While heat is a factor that will afect this, overall the number of charge cycles the battery has will remain fairly constant.
You will find if you are using the phone the way you are you would be charging the battery more often and it is this increase in the number of charge cycles that would be shortening the battery life. Does that sort of answer your question?

After playing 60-70 songs on shuffle battery life is almost all gone.

Well the subject says everything...
Basically after I play 60-70 songs on shuffle, the battery life is almost gone. (After being fully charged) I don`t know if this is part of the reason why it only plays that many songs, but I do turn my ipod on an off a few times. (About 4-5 times?) But I don`t think that`s a good enough reason for the battery to be so low after playing only about 3-4 hours. I don`t have any songs that go over 5 minutes and I don`t watch videos or put on the slideshow while playing music. And the only times I touch the click wheel is when I want to raise/lower the volume or skip to the next song. So I don`t know why it only plays for such a short time. Does anybody know why it`s doing that? And is there any way I can fix this?
Windows XP

Try just letting your ipod play one song over and over, and see how long it lasts. If it still has the same problem, get the battery replaced.

How long can you play mp3's/maximum battery life?

What is the average battery life for a 30 gig, early 5th generation Ipod video? I'm asking as I get about 5 hours using Apples instructions for maximum battery life.

Usually, the battery life for the original Fifth Generation iPods was approximately 12-15 hours, I think, although I'm not perfectly sure about that estimate.
Anyways, about 5 horus is not normal for your iPod, and I woulkd suggest that you send your iPod in for service (if it is still under warranty).

Satellite A215-S4757 - Battery life and cooling fan issue

Hello everybody,
I would like to ask a few questions abou my system: first of all, the cooling fan is running in my opinion too often: almost continuously, with brakes of 2-3 seconds. Is this normal?
I have my laptop since august last year and I think it shouldn't be a problem of dust, because it is too "young" for that and I don't live in a "dusty" appartment...
Anyway, I think the "almost allways running fan" problem appeared about 2 months after I purchased the notebook. I have installed "Speedfan" and I see "HD0" temperature is increasing from about 30deg immediately after I start the laptop, to about 39deg after 1 hour.
But the curious thing is that so named "Core" temperature is oscillating from the beginning between 45deg and over 52deg! The fan starts each time the core temperature is rising over 50deg and stops when the temperature reaches 45deg. Is this behaviour normal???
Is the core temperature of 45-50deg normal? I am just using my laptop for Internet browsing, e-mails, etc., no complex 3d games!
The second thing is that the battery life is (and was from the beginning) not spectacular: it lasts max. 1,5 hours with wireless on, but normal use of laptop (not playing dvd's or something like this). Is this normal? If yes, is it because of the amd turion 64x2 processors?
Please help me with some advices / opinions.
P.S. I've bought my Toshiba as I was on trip in USA (NY).
Thank you very much in advance.
Conrad

> I would like to ask a few questions about my system: first of all, the cooling fan is running in my opinion too often: almost continuously, with brakes of 2-3 seconds. Is this normal?
Im an owner of a Satellite A210. Its similar to the A215. The A210 is a European model and the A215 belongs to the US notebook series.
I have noticed the same on my A210 and I think its normal behavior.
> But the curious thing is that so named "Core" temperature is oscillating from the beginning between 45deg and over 52deg! The fan starts each time the core temperature is rising over 50deg and stops when the temperature reaches 45deg. Is this behavior normal???
The CPU temperature of 40-60deg is nothing unusual.
The temperature could arise up to 70-80degrees while playing a game. So dont worry about the temperature.
The cooling modules are controlled by BIOS. The fan table is stored in the BIOS and it contains informations about temperature limits and the cooling usage.
If a certain temperature level was reached the cooling module starts to rotate with a certain speed.
Now I would like to say something about the notebooks battery life time
Generally the battery life time depends on the notebooks usage.
While playing games or watching movies the battery would discharge much faster.
Anyway, your notebook was equipped with high-performance devices and as far as I know the Vista was preinstalled on this series. Both factors (high performance devices CPU and GPU) + Vista OS need a lot of battery power. Vista needs more notebook resources as the Win XP and therefore notebooks with Vista OS run shorter on battery as the notebooks with preinstalled Win XP.
Last but not least you have to know that there are different battery models A stronger battery with higher *mA* value would help to run the notebook longer using the battery power.
Hope I could clarify this question.
Bye

Battery life on Macbook Pro (3 hours?)

I just got this laptop. It's a 15.4" MBP. I installed Snow Leopard on it from the upgrade DVD (from Leopard). All is well, but the estimated battery life is around 2:30 - 3:30. I've had the battery on charge for days and the button on the left of the mpb indicates a full charge.
Is it some services that are running? Is the estimate just way off (I know they usually are)?
My brightness is 3 blocks from full. I have iTunes (playing), Terminal (no activity), Adium, MacVim, iCal, Firefox running. Does this sound accurate?

i have a unibody late 2008 w/c lasts about 2Hrs+ or 3Hrs max. is your macbook pro the built in battery?early 2009 and mid 2009 model?if so that doesn't sound right since the built in battery have 7hrs battery life "ideally" but reality its just 4-5hours. I've tested 3 of them already and all have same behaviors.(2mid 2009 macbook pro and 1 early 2009 macbook)
Airport: off
Bluetooth: off
Brightness: 2 bars
only running: safari and quicksilver
no external device plugged in
no CD inserted
have the latest battery update and firmware update
so yeah not a bug not an issue with battery but that's just how it is. Macworld already did some lab bench test on their own and so did the other mac fanatics. I just don't get why sometimes Apple says it will last 5hours if it won't.

The battery life in MacBook Pro is not 7 hours

Hi, everyone
In the website it says that the battery life is 7 hours, however, my battery dies after 4:30 hours!!
though my Mac is new
HELP!
Thank you all in advance

Welcome to the Apple Discussions!
It is a good idea to run the new MBP through several calibration cycles, instructions here:
http://support.apple.com/kb/HT1490
The calibration helps your computer know when the battery really is low, otherwise it will keep more charge available than it needs to when it shuts down so that it doesn't have to shut off after going to sleep.
Here's another article about helping the MBP last longer when running on battery:
http://support.apple.com/kb/HT3557
Apple says this about their battery life claims:
About Apple battery life claims
Published battery life is based on a light duty test that involves wirelessly browsing various websites and editing text in a word processing document with display brightness set to the middle setting.
The more intensive the usage of a computer, the faster the battery will drain. For example, while a MacBook Pro (15-inch, Mid 2010) used as described above can get up to 9 Hours of battery life, the same MacBook Pro computer continuously playing DVD movies with the display set to full brightness will drain the battery more quickly.
Hopefully this will help you get more enjoyment out of your computer.
Best wishes. Joel.

Battery Life on my 17" MacBook Pro

Hey guys,
So I just bought a early 2011 17" MacBook Pro and was wondering what the battery life should be like. I have the brightness on half, keyboard lights on full, and I have been on facebook, apple, and watching a movie, and the battery life is already on 63%. I don't know if this is normal, or is there something wrong with my battery? I called applecare and they said that it just depends on usage, but I'm still kind of worried because the computer was $2458 and I want to make sure that everything it in check for this kinda of money.
Please answer/reply soon!!!!
Alexander

So would what I was doing be considered heavy usage? Thanks for answering
Depends. Screen brightness on half is good, but keyboard lights on isn't. If you're using the internet, presumably you're doing that wirelessly, and having AirPort turned on drains power faster due to the need to constantly broadcast radio signals. (Bluetooth is the same.) Watching a movie isn't a low-power thing to do, and if you were watching it from a DVD in the optical drive, keeping that spinning eats even more power.
What you were doing isn't as high a usage as, say, playing a graphically-intense 3D game, but it's not something that will help your battery last longer either.

New MBP 17 - When playing DVDs/CDs rattles/vibrates every 10 seconds

Hi everyone. Love the new machine but wondering if this is really normal. While playing DVDs, about every 7-10 seconds there is a ridiculous rattling/vibrating sound, sort of like the noise a 12-year-old air conditioner makes when it's on and the glass and window frame are shaking every few seconds. This can't be right. I assume I need to take this back to the Apple store -- or should I mail it back myself via Apple repair?
Or are all the drives like this? I just can't imagine anyone being okay with a DVD soundling like a tire going over the warning treads every few seconds...
Thanks
John

Hey guys,
I notice there's a few topics going on for the 17 inch MBP now, so I thought I might help out. There is a topic here where some of us have been posting about the same problem:
http://discussions.apple.com/thread.jspa?threadID=2162948&tstart=45
I previously had this problem with my unibody under Mac OS X (with 5400rmp Hitachi HDD), and I found a post on the big 100 page thread with someone suggesting a utility called HDAPM which might help. I have found that this utility did indeed help on my 17 inch unibody, I haven't seen a single freeze since running it, the machine is smooth as could be. Others in this topic appear to have had similar success.
I posted some instructions here on how you can install HDAPM and set the necessary setting via terminal:
http://discussions.apple.com/message.jspa?messageID=10283888#10283888
Maybe some of you guys should try it. One thing, this apparently may reduce your battery life slightly, but I haven't noticed anything too drastic.
For anyone who does try, let me know if it works for you.

Battery Life on a new vs old battery

Hi I've just bought the HP Pavilion g4 (1100au) and ran the battery check utility.
I noticed that the battery is already 6 months old. How does this affect the life and capacity of the battery? And will the warranty cover the fact that the battery is already 'old' at purchase? (E.g. if it's below expected performance for a 1 year-old battery one year after purchase, will the warranty replace the battery?)
Although there is no mention on the HP site, some online stores selling HP Pavilion are claiming a battery usage time of just over 4 hours (not using dvd drive or playing graphic-intensive games). Is this correct? What should I expect in a year's time, in 2 years' time and in 3 years' time?
many thanks
This question was solved.
View Solution.

Any site about battery life and usage will tell you that it depends on the number of charge cycles and the level of charge that you keep the battery at.
If you keep a battery at 100% it will decrease the life significantly. That's why a new battery will ship with a charge of say 50% or 40%.
Getting 1000 cycles or even 500 cycles out of a Li-ion battery is overly optimistic, at best. Older batteries would degrade over time until the MAh would go to 0. They would also heat up during charge cycles and have minor shorts in them which would be disregarded by the battery board. A short in a battery is a major problem.
Nowadays, batteries have smart chips in them, a temp monitoring diode, lots of safeties. If the smart chip detects the smallest defect in a battery, it will just shut it down. That's why you see seemingly good batteries just all of a sudden stop working. Once the Mah rating gets down to about 50%, a battery could just shut down at any time.
Aftermarket batteries don't have these safeties built-in to them. Most of them don't even have a temp diode. They just show a static temp all the time. So, they could short out and start a fire, they could overheat and take out your laptop charging system or worse. I've seen worse, it's not pretty.
I don't do anything to increase the life of my batteries, I just keep them at 100% charge and use them. I'm lucky if I get two years use out of a battery. Usually I get one to one and a half years out of them. After about 100 charge cycles, they start to degrade the mAh rating. If they make it to 50% without shutting down, I just replace them.
Batteries aren't even considered a component anymore, they're considered a disposable commodity.

Battery life percentage jumps around

Hi!
My macbook pro is about a year and a half old. I've never had a battery problem until about two weeks ago. I use the percentage display for how much battery life I have left, and when I unplug my computer, the number jumps around a lot. I've been unplugged for about an hour, and it has jumped from 80% to 30%, then up to 70%, and now it's at 50%. Also, the computer tells me I'm running on reserve battery power after at random intervals, even when the icon says I have more than half of my battery left. Sometimes it tells me I'm on reserve after 20 minutes, when my icon says I have 80% left; other times it waits an hour and a half when it says I have 30% left. I've recalibrated it, which didn't help. I'm a student, and generally only use Safari and Microsoft Word, though occasionally I'll play a DVD.
Does anyone have any ideas about how to fix it? I've been a devoted Apple user for years and I've never had any problems like this before!
Thanks!
-Kate

Be aware though that the battery % remaining will fluctuate on any notebook computer. I have a late 2009 MBP and this happens depending on what I do on the computer. I go to a website and the remaining time will drop. If I wait a few minutes and not touch the computer, the remaining time will go back up till I use it again. The remaining time shown will change depending upon how much power the processor is consuming at the moment.
I actually had two late 2009 MBP and this happened on both of them.
But yes, to the OP, the battery is old, and when you replace it, the remaining time will still jump around and it is normal.

Satellite M50-164 and Battery life

Battery power only lasts 1 hour tops. Is this normal, laptop only 2 years old.

Only 2 years!!! Sorry buddy but 2 years for mobile computer is long period of time. After 2 years battery can be defective, notebook can be full of dust and so on.
So, after 2 years is normal that battery hasnt so much poweras new one and 1 hour is OK time.
The question is what you do with it: watch DVD move, play a game or just write mails. As you know battery life depends on notebook usage.

Battery life for macpro

how much does my battery has to work?

If your query is how long the battery will last be for necessitating a recharge is dependent upon what you are doing. Watching DVDs or playing games will deplete the battery very quickly. Also influencing battery life is what and how many peripherals you have attached. Simple word processing and web browsing will extend the time. Rarely, if ever will you attain Apples published figures.
Caio.
