Battery lasts less than 2.5 hours

My MacBook Pro is 3 months old and after installing all my apps and accounts I noticed my battery only lasting 2.5hours on a full charge. I brought my issue to the forum and came to the conclusion that Google Chrome is known to use a lot of CPU and energy, so I wiped the hard drive and did a clean install of OS X 10.9. Without reinstalling Chrom (I used Safari) my battery looked great for about a week, 6-7hours on 100%. But now suddenly, same issue has returned. No more than 2.5 hours on 100% battery. I also notice that the machine is pretty hot especially when comparing it to colleagues MacBook Pro's of the same model.
Here's the latest screen shot:
Can anyone suggest what could be the issue? I am on the brink of returning it to the store.

1. Follow these instructions, or these for OS X 10.9 or later.
2. In the Energy Saver preference pane, uncheck the box marked
Enable Power Nap while on battery power
if it's shown (it may not be.)
3. You can also try resetting the SMC.
4. Make a "Genius" appointment at an Apple Store, or go to another authorized service center.

You iPod is broken. It appears it is more than the screen and maybe more than the battery.
Apple will exchange your iPod for a refurbished one for $199 for a 64 GB on and $99 for the others. They do not fix yours.

A third-party place like the following maybe less. Google for more.

My iPhone 5 battery last less than a day, help

What should I do to have a longer battery life on my iPhone 5. I do not use any apps, I only use the phone -and not so much- and check email messages, yet I have to carry my charging cable everywhere because by 5 PM my battery dies. My blackberry battery lasted 3 times more.

Things I found that eat my battery fast:
LTE on.
WiFi on when no WiFi available (constantly searching)
Location services on when not needed
Rarely do I need LTE speed, so I just turn it off and go 3G. You might give it a try.

Battery lasts less than 3 hours

So I have had my blackberry for a bit over a year now. And it was all working fine until a couple of days ago.
Now the battery only seems to last for about 2.5hours, from being 100% to shutting off because of low battery. I havent got applications running in the background, and have read and followed all of the maximise battery life posts.
I used to be able to leave it for a day or more with it being fine.
What can I do to solve this, as it is really inconveniencing my life at the moment, because it just isnt staying on long enough for me to do anything.
If this is any help, I am on Orange.
and its a blackberry curve 8250 and the battery says 'capacity 1150mAh' and C-S2.
HELP!
Thanks

Replace the battery, I don't think BlackBerry will supply them but they're all over Amazon and eBay for as little as £1.50.
Let it completely shut down from full for the first 10 or so charges to help strengthen its life. Should last at least all day with this.
Try and avoid leaving it on charge when its 100% too.

The battery of my MBA 13 "mid 2011 is lasting less than two hours after installing the Mountain Lion. Would be the OS or apps consumed much?

My MBA is consuming the battery in less than two hours after I installed Lion Mountain. The update has already been done for some time. The problem of consumption would be the same OS, according to several complaints, or were inadequately apps consuming battery?

Please read this whole message before doing anything.
This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
The purpose of the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login, by a peripheral device, by a font conflict, or by corruption of the file system or of certain system caches.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards, if applicable. Start up in safe mode and log in to the account with the problem. You must hold down the shift key twice: once when you turn on the computer, and again when you log in.
Note: If FileVault is enabled, or if a firmware password is set, or if the startup volume is a Fusion Drive or a software RAID, you can’t do this. Ask for further instructions.
Safe mode is much slower to start up and run than normal, with limited graphics performance, and some things won’t work at all, including sound output and Wi-Fi on certain models. The next normal startup may also be somewhat slow.
The login screen appears even if you usually login automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
Test while in safe mode. Same problem?
After testing, restart as usual (not in safe mode) and verify that you still have the problem. Post the results of the test.

After upgrading to iOS 5.0.1 in my iPhone 4 the battery lasts less by a 30%, it´s only me?

After upgrading my iPhone 4 to iOS 5.0.1 the load of the battery lasts less by 30% with the same use it had before. So far I read the upgrade was to correct the battery duration flaw. So ¿What happened?

It is your responsibility to backup your purchases.

My iPod Touch [gen 3] battery suddenly is lasting less than an hour.

I've had my iPod since the summer of 2010. It's worked fine up until the last week or so. My original cord's white covering started to fray and you can see the silver wire protection, so I bought a new one. That one worked fine, but then it started giving me a screen on my iPod that said "Charging is not compatible with this accessory." And about three months ago, that cord just stopped working all together. So, I switched back to my original after putting electrical tape on it and it charges with no problem now. Well, now it's three months later and my iPod is suddenly only holding a charge for less than an hour. I put it on the charger when I go to bed, and take it off when I wake up. The only other time it goes on my charger is when it dies suddenly, or if I'm listening to it in my car because it charges it automatically when I plug it in through the USB cord to my CD player in my car. But, I'm really ticked off that it's already breaking because it's only 2 years old, and I can't afford another one.
Does anyone know what could possibly be making my iPod die so fast? I have notifications turned off of most of my apps, the only exception is Draw Something, Facebook, and Words With Friends. I have my brightness at the medium setting. And I've deleted a lot of apps this morning in case that was the problem. I don't listen to music that often on it, when I do it's when I plug it into my car. I mostly play games and stuff, but I took it off the charger an hour and fifteen minutes ago, and within 45 minutes I got the notification that I had 20% battery left.

1. Check the cycle count of the battery. It may be due for replacement.
2. If not, follow these instructions.
3. You can also try resetting the SMC.
4. Make sure your system is up to date in Software Update.
5. Make a "Genius" appointment at an Apple Store, or go to another authorized service center.

Battery lasts only up to 2 hours??

I just got my brand new 2nd gen iPod Touch today (32 GB) and completely charged the battery. After less than 2 hours of use, probably more like an hour and a half, the batter was 3/4 of the way down. Shouldn't it last longer than this? Could there be something I was doing that wore the battery down so fast?
Thanks!

all the battery articles/threads say turn the wi-fi off if you aren't using it. BUT in my personal experience it acts more like a mobile phone trying to find a network. if you are within range of a wifi network you have access to, having wifi switched on won't really effect your battery that much. if you aren't, and it is constantly looking for a network, the battery will go down much quicker.
that's if you aren't using it. i listen to a 3 1/2 hour radio show over wifi, this will drain the battery quite drastically.
joaquinx is right about the brightness, you should have that set on the lowest setting which is acceptable to you.
it also depends what you are doing with it. are you playing videos/games? they will drain the battery very quickly. if you are just listening to audio, the battery will last much longer.

Battery is less than year old. Not holding a charge. Now what?

I Bought a new battery less than a year a go since the original wasn't holding a charge. The new one is doing the same thing. Now what do I do?

Did you buy a battery directly from Apple or a cheap third party knock off? Experience has taught me that you get what you pay for. Buy a better battery and follow the tips here for maximizing it's life.

Screen Saver lasts less than a second (Wireless USB Mouse)

When I put my pointer in the hot corner (lower left), the screensaver activates for less than a second, then goes off as if I've moved the mouse or pressed a key. The pointer disappears, then reappears immediately in the corner before the screensaver goes off, so that makes me think the computer is thinking that the mouse is moving (which it is not) and thus turns off the screensaver.
I recently updated to Mavericks with the exact same mouse I was using before, which is a Microsoft Wireless Mouse 5000 with Intellipoint installed. The only way to switch off the mouse would be to disconnect the USB or remove the batteries from the mouse.

Also, the screensaver is set to go on after 20 minutes, but it never does.
Any advice/help would be appreciated.

The problem is no longer there. Repairing permissions may have been the solution, but I'm not sure because I tried a lot of things.

HT1338 The battery life of my Macbook Pro lasts less than what is indicated in the specs. It is a real nuisance!!! especially when I'm in a meeting and have to utilize my Mac laptop!

I am having trouble with the duration of my Macbook Pro battery. It does nt lasts as long as what is indicated in the battery specs. Is there something wrong with my battery? I have charged it as required when I bought my Mac. Is this another overlooked and over-estimated presentation of Apple? Please enlighten my perceptions regarding this matter. Thanks

how old is the battery? How many charge cycles are on the battery?
You can get this information by opening the application "System Information" in the folder "/Applications/Utilities". Select the informtion from the "Hardware > Power" section
It should look something like:
In this case I have 35 charge cycles on the battery. The larger this number the more likely it is that you will have less actual usable capacity.

100% to almost 60% battery in less than 1 hour - normal ??

I have had an iPhone4 since a little after they came out. I am such a light user of the phone that I have never had to worry about the battery, and even when I am taking pictures making calls I don't even remember ever getting below 60%. I charged the phone every day and mostly kept it on whatever charger was closest to me.
Now, I have upgraded to an iPhone5 for Siri, the Maps, the better camera and sound, image stabilization, nicer display, etc.
The other day I was pretty excited about trying out my new phone's maps, so I took about an hour drive to meet my girlfriend after work, and we went to see a movie. The phone was 100% charged when I left.
I had GPS going I guess with the maps, no other apps going or in the background, but I did have music playing through the headphone back to my car stereo.
I was blown away that when I got to my destination and the next time I looked at my iPhone it was about 60% charge. I estimate it was about an hour or continual use like that. Do maps/GPS use a lot more power than normal?
Is this normal? Do I have a problem? Are there things I can do to cut down on power usage? I already have the screen about as low as I can set it and still be able to see it. Any FAQs on this issue?

Thanks woodmeister ... that's kind of the conclusion I came to.
the first thing I did was to buy one of those expensive little power adapters so I can charge my phone while I am driving ... which I guess does not help me if I am riding my bike?
While my iPhone does not really discharge so much it does not seem like the phone charges much either, which leads me to think there is a problem.
My iPhone is only about a week old so it is not one of the early ones. I just do not know if this is normal?
Do you know if Apple has some concrete way to measure the iPhone battery to some standard they set?

After upgrading to Mountain Lion today, my battery only lasts less than 1:30 and the fans seem to run constantly. Help?

I have a late 2011 13" MBP with a 2.8 GHz i7 processor and 4GB of RAM. With OSX 10.7, my battery could last over 4:30; however, now I see the battery drop a percentage point about every minute (currently at 81% and it says 1:16 remaining). I have a number of programs open (Chrome, Mail, iTunes, Twitter, Skype), but these are the same programs I almost always had running with Lion and I never had this problem. Something else new is that the fan seems to constantly be running and only turns off if I put the computer to sleep.
Here are screenshots of my activity monitor: http://imgur.com/a/shehM
Any advice?
My battery has decreased to 70% (1:07 remaining) by the time I've finished writing this...

It looks like Skype is basically running two CPU cores at nearly full throttle (well, 1.57 cores). That's bound to drain the battery pretty quickly. If you were not doing a high resolution video chat in Skype when you took that screen shot, then something is very wrong with it. Check and see if there's a newer version of Skype available that fixes the problem.

Apple TV does not load rented items from iTunes in less than three (3) hours depsite YouTube, Netflix and network being fine. How can I get Apple to actually provide the iTunes service I am paying for?

I'm just tired of waiting on this inept device and it's underserved iTunes counterpart being unable to deliver enough bandwidth to load a show within a reasonable amount of time. I'm a big Apple fan and an equally big critic. This whole rig is a big FAIL so far, Apple. There is nothing ON DEMAND about the iTunes Store at this point. Netflix and YouTube work better on Apple TV than their own iTunes Store! And, this has been going on for a few years now, unremedied, and is only getting worse with more people buying these devices! I do not reccommend this device to people like I used to.
The good news is, that iTunes will give refunds about 85% of the time if I explain my problem the way I have here. SO, ATTENTION: EVERYONE WITH AN APPLE TV: If you have this same issue with iTunes Store not properly serving your paid content, do not hesitate to ask for your money back. It's the least they can do for the amount of life wasted waiting for a show to load. Not to mention, all the disappointments with the kids at bedtime and when my wife and I want to just relax and turn something on.
Bottom Line: ITUNES IS UNDER-SERVED!!!
OR
There is a massive conspiracy by cable and DSL ISPs against Apple taking away TV viewers. Is it possible the ISPs are somehow limiting or buffering the data packets coming through the port(s) employed by iTunes Store? Like I say, with me and many others on this forum, the problem lies solely with iTunes Store. Youtube, Netflix, Podcasts and everything else generally serve up just fine. The iTunes Store, however, is a consistent failure. Something that seems unusual for Apple not to address, being so customer-centric and all.
Please share any links or insights you have here so the faithful might get to the bottom of this incredibly annoying problem. I WANT MY ATV!

There is a massive conspiracy by cable and DSL ISPs against Apple taking away TV viewers.
Most networks are overloaded and operating at full capacity. However, a solution is coming.
Technology experts are working on a movie storage system where YOU have physical possession of the movie.
This system stores the movie digitally on an optical disk system that will not be dependent upon a congested, complicated, and fragile network.
Because all of the data is stored only a few feet from your television, all the bottlenecks are removed. Performance and reliability are virtually flawless.
Further, the system will not utilize any form of security codes, authentications, or passwords. Once the optical disc is purchased it can be moved around freely at will, and can even be lent or given to friends and neighbors with zero hassles.
