MBA 11" battery life only 2 hours out of the box.
Should I have it replaced under warranty?
Out of the box... did you actually fully charge it? I somehow doubt it. Laptops are shipped with partially charged batteries to ensure they work. Read the instructions and let it charge for the appropriate time and try again. If it still does not work... take it back.

Hello everyone I come to you tonight with a question regarding my Macbook Pro's battery life.
This computer is fairly new, it was purchased in September of 2011. At the time I was getting the advertised 6-7 hour battery life.
As time goes on, I do understand that the battery, will wind down. As of right now, I'm at 147 battery cycles and my batters "hp" (whatever that means, I don't know how that's measured.) is at 95%.
So with that, I'm now only getting 3-3.5 hours of total battery life, with my bluetooth off, and I'm only doing minor web browsing, with no flash. I'm writing this, with the only other application open being iTunes, and my timer is at 3:35 minutes @ 97% battery. My keyboard backlight is off, and my screen is only on 3 dots of the total possible. (Sorry that's very poorly described, I'm not sure of the proper way to go about it.)
So I'm wondering, is there anything that I could or should do to fix this?
The specifications for my computer are as follows, for those interested.
Mac OSX 1.7.2
2.7 Ghz Intel Core i7
8 gigabytes of ram

MacBook Pro 15" i7, out of the box w/problems
My MacBook Pro is brand new out of the box, less than 48 hours, and I'm already having issues with it.
Before the first 24 hours out of the box, I got a message for a forced shut down (see image here: http://www.mactropolis.com/wp/wp-content/uploads/2009/01/macosxkernelpanic.png)
The following day, after coming out of sleep mode, I found it with a scrambled screen.
I haven't installed or transferred anything onto it whatsoever, but just been using Safari. I've heard that people are having problems with using Safari with webpages using Flash, but that might not explain the forced shut down.
I ran disk utility after the forced shut down and a few permissions were fixed but there were no other problems. After the scrambled screen, I ran an extended hardware test twice, and no problems were detected
I'm not sure there are any grounds for taking this to the Genius Bar, but I'm rather irritated for this to be happening when I haven't really started using this computer for more than browsing the internet.
Any suggestions? Might it be as simple as using something other than Safari?The solution is extremely simple, return it for another. If you bought it from an Apple Store it should be no problem. If you bought it from an Apple Reseller you need to deal with them directly.
Don't wait, do it today.

A1281 is the battery i got for my 15inch MBP. Is the battery life only 2 - 3 hours for a new battery on this device.
This is from Apple.
2 to 3 hours seems very low.
what is teh standard or advertised spec for a 15 inch Macbook Pro with this battery.
I would like to know so that i can return it if this is not normal.
Its expensive so comments would be appreciated.I say it depends on your model? average usage is about 3-4 hours depending on what you use and how you use it. Adobe Flash player eats a lot of battery power so if you are on a web page and has flash player, likely that it's eating up battery because of it's power thirsty.
Also check your systems activity monitor. It could be possible that one of your program/apps did not close right and may be still running. So check for that and end the process if necessary.
If you have a backlight keyboard, in a broad daylight, it's not necessary to have it on.
I also suggest that you use it plugged in most of the time, and it's not going to hurt or damage the battery if you have it plugged in all the time. Only use on battery if you are going to places that has no access to the outlet. If you are at home, then keep it plugged in. Just keep in mind to fully drain the battery until it your MBP turns off on it's own. This is the calibration process so that you have the most accurate battery readings.
The standard for 2011 MBP is 7 hours on battery. Before that model is 10 hours, but i don't believe that previous models will last 10 hours. Last week I calibrated my battery readings from fully charged and it took 9 hours to completely drain out the battery (I have a 2011 model),
If you think it's not normal and that your battery doesn't meet your expectation then set up an appointment with the genius bar and have them test the battery. They will determine whether it is faulty or not. -
W520 - Battery Life Under 2 Hours!
Hello there!
I've been experiencing the problem where my Nvidia Graphics card does not automatically switch to the Intel Graphics card --- or if it does --- it does not allow me to have the 5 hours + of battery life that I use to have when I was using Windows 7 (right now I am using Windows 8).
I also don't have the Lenovo Power Manager program installed because I can't seem to find it anywhere on the installation pages for my particular laptop with Windows 8. I wonder if this is the problem since its using Windows Power Manager -- even though I have installed the Power Driver multiple times.
Even when I get it so I make sure that no applications are using the Nvidia Graphics card (confirmed by the Nvidia GPU Activity icon), I still get the under 2 hours battery life. I am using the 9v battery -- the larger one.
Any help would be greatly appriciated so I can get the full battery life out of this laptop, as when I had Windows 7 installed. Thank you :-)Hi brooklotzkar
1. Go to Control Panel (Small icons)> Lenovo - Update and Drivers > Install all critical and recommended updates. Optional - Up to you to decide as you may not be using all the functions. If this options is not available, Download here and install.
2. Go to Control Panel > Power Options > Check Power saver. Power Plan make a big difference on both battery life and performance.
From what I tested on my W520 - Core i7 2720QM
Maximum Battery Life or Power saver: CPU clock speed at 800MHz constantly, but performance decrease. You wouldn't want to multitask too much when on battery.
Maximum Performance or High Performance: CPU clock speed will go up from 3 - 3.2GHz (Depending on how many core / thread the program will utilize)
3. Battery will vary depend on how many / what kind of apps are opened. I have tried using 5+h on 6-cell battery without any problem. (Battery Stretch, only running Microsoft Word and 1 tab of Internet Explorer) It is recommended to run Internet Explorer on battery as it requires less resource, hence battery life will not run out as fast.

I have Snow Leopard (10.6) installed. Why is this happening?Hi LeonardoGolden,
You should definitely be getting more than 2 hours with that sort of Full Charge Capacity on your machine. I have the same model and a slightly lower battery capacity and I'm getting 4+ hours of web surfing and document composition.
Out of curiosity, how is the machine being used? It's obviously a pretty new unit (with only 3 cycles), if you go into Activity Monitor, change the drop down to "All Processes" is there anything consuming more than 10% CPU load? What applications are using during this two hour window? -
I have an iPhone 4s just eight months, it is normal that the battery lasts only 3 hours? please help me thank you very much.
Three hours if definitely NOT normal. I get at least 48 hours out my 2 year old iPhone 4S' battery with light usage. Did you do the iOS 7 update on the phone it self (OTA) or through iTunes? In my experience most problems are caused by the OTA updates. For this reason I ALWAYS update using iTunes on my computer.
I would suggest restoring your phone using iTunes on your computer and setting it us as a new phone. This downloads a fresh copy of iOS 7.1 from Apple and installs it on your phone. Just make sure that you transfer all purchased items (apps, music, etc.) as well as photos to your computer before restoring as the restore will completely wipe your phone. Do not restore from a back-up. Yes, you will loose all your data on the phone but restoring a back-up can restore the problem you are currently having back to your phone. Once your phone has been restored you can manually sync back your apps and music.
Before restoring you can also check to see that battery-killers like Location Services, Background App Refresh, etc are only turned on for the apps that really need it. I recently read and article that said that the Facebook app can be a real battery killer. If you have this app installed turn of location services and background app refresh for this app and see if that helps. Also go to Settings / General / Restrictions / Location Services / System Services and turn off all the options in that menu. Your phone does not need any of those to function. Constantly using your phone's GPS is a huge battery killer. I only have Location Services enabled for Find my iPhone and Background App Refresh is turned off completely.
I hope this helps. -
I have a MacBook Pro 13inch 2.4GHz (Intel Core 2 Duo, 4Gb RAM, 250Gb HDD, NVIDIA GeForce 320M graphics, SD card slot, up to 10 hour battery life) bought in October 2010. The charger has been playing up for a while now - the light going out but coming back on when I move the cable a bit - faulty connection it seems. It has now stopped working at all.
Apple UK charge a whopping £65 for a replacement - and the reviews are AWFUL for it!
I need to know which one I need - 45w, 60w and 80w are listed - can someone tell me please? If I'm going to pay this price I want to make sure I get the right one!
Also, is a genuine Apple one available on Amazon UK, does anyone know please?
Any help will be much appreciated.
Meanwhile my battery is going down.....Thanks for that wjosten. Much appreciated.
I've read here on Apple's site that the 85W version will work, as you say, and that it would run cooler with a 13" Macbook - I have a 13" MBP of course but assume this would be the same with mine. I wonder if running cooler is a good thing (it sounds as if it is) and it would be better for me to get the 85W version than the 60W one?
Then I have to decide whether to pay the (extortionate as it seems to me, though I may be wrong) £65 from Apple (bearing in mind the rotten reviews here of the Apple product), or risk a cheaper alternative from Amazon UK, at around £20 (also with various rotten reviews)... Any suggestions? Please? :-) -
6 hr battery life on a Droid Eris out of the box
Hello eveyone.
I need help I just changed my blackberry storm for the Droid Eris.
Right out of the box and charged the battery lasts 8 hrs tops then it's decresed to 6 hrs.
THhis drop was due to my twitter and facebook usage which is very low and some emails that come in now. I cant surf the net due to the battery drop.
My old storm would go on for 2 days 1 full day with heavy usage. This is a new phone...what gives?
Thx.It isn't the phones fault. It is due to an under amped battery. It is a strong phone that needs more juice. I would be hard pressed to believe the motorola droid or any other android phone has a huge difference in battery time. If there is a huge difference you don't use the phone as much as some of us do then. I purchased the 1750 battery from seido. Would have got the next one up the 3500 if it had been the price it is now. I recommend buying two and an external charger. I am getting ready to buy another 1750 and charger. This will increase the life of the battery for two reason primary reasons. Proper time for charging and the fact it isn't in use makes the charging cycle much better and effecient. I work in a hospital and get my phone searching quite often, from one netowork type to the next. I can get a solid 12 hours with 20% left at thend of the night when I get home. I have FB chat up litterally all the time bloo, I don't twitter that much but I get updates. I get mail pushed via gmail now. I do use wi-fi off and on as well. Since I'm in doors I don't actually leave the gps on, waste of power in general. Any of the newest smartphones have an underpowered battery. BB doesn't use use the web in the same fashion as android does and it isn't multitasking which is one of the big killers ont he phone. Use a task killer, select the improtant apps to ignor and make sure it cancels stocks and mp3 store, waste of cpu there. You can maximize the power you get with the battery you have, but the 3500, will add a small bit of thickness, but who really wants a hardworking model for a phone. She (the phone) just doesn't feel the same. Sorry to ramble so much, but it gets me when people say it is the phones fault or HTC is the cause. I disabled sense UI for a week and used the open UI that android has. I lost an hour and a half on the average daily, so I have to say from doing that and then turning it back on and getting the missed time back sense UI isn't the cause. I didn't notice any extra pps running when I used the open UI so I have no idea why it acted that way. It coudl have been caused by background jobs that the Sense UI uses but wasn't since it wasn't enabled and the services still ran, now that I mention that I need to check that out. It is the wrong battery fo the job, plain and simple. Replace your moto droid batteries and you will see a huge difference too. You can charge the new batteries for less time(4 hours or less pending on charger) and they will say full, but you get bad results when you short change your batteries charge time. To get the most out of my batteries, I charge them for a full 8 hours, the reason I am getting another battery and ext charger with dock.(http://store.androidcentral.com/mobi-products-cradle-w-spare-battery-slot/5A100A6693.htm) and the battery I am getting (http://store.androidcentral.com/seidio-innocell-1750mah-extended-battery/8A37A6399.htm) or the bigger battery (http://store.androidcentral.com/seidio-innocell-3500mah-extended-battery/8A37A6374.htm) You can find better prices but these are for reference. A note on airplane mode: It disable all radios in the phone. You will not receive calls and txt/mms messages. Basically it turns your phone into a PDA. You can enable the wi-fi for access. Since I replaced my battery I don't do it that often but sometimes I find it neccesary to use airplane mode for some of the remote desktop use I do on my phone.

How can you get OS Lion back if you already downloaded Mavericks? I CANNOT live with the battery life of 2 hours!! HELP
Kappy wrote:
Don't downgrade OS X without first erasing the drive. You cannot restore a Time Machine backup of Lion directly on top of a later version of OS X such as Mountain Lion or Mavericks.
When you "Restore from a Time Machine Backup.", the drive will be erased for you, but yes, won't hurt to:
Boot into Recovery (hold ⌘R on boot)
Utility->Disk Utility->Erase Macintosh HD, then Repair Macintosh HD
Quit Disk Utility
Then Select: Restore from a Time Machine Backup. -

after making a call I put my phone in my pocket and when I bring it out to make a call the player is on killing battery life. How can I shut the player off or prevent this from happening?
Try to position your iphone that the screen is facing away from your skin.
Make sure that the back part of your phone will be the one that will contact your skin inside your pocket
Thats what i do:) -
I will be playing some 3d games and it says the battery is 90% but I'll turn off and turn in back on it about 30 minutes and the battery is only 70%. Why is the reading so inaccurate? I understand that 3d games on high brightness will drain my battery quickly, but why doesn't it tell be how low it is to begin with? The other night it said it was around 35% and I turned it on in the morning and it was only 3%?
Sorry there are some typos above, but you should be able to figure out what I'm asking. Let me know if you have tha same problem, know how to fix it, or know if apple is aware of the problem and is adressing it in a future update.

So I just ordered my first Mac book Pro. I took it out of the box and hit the power button to do the start up and the screen will not work at all. I shut the computer off and back on again. I plugged it in and unplugged it. I've done everything I can think of and the screen still stays blank with no life at all
Is the battery charged? Press the little button on the left edge, near the front. If no green dots, no charge.
Does it charge? When you connect the MagSafe charger, does the pilot light on the plug light up?
Does it actually start? Should sound a chime after you press the power button on the top/right corner. If it chimes, does the Caps Lock pilot light when you press it?
If it starts and Caps Lock does flash on and off, have you tried pressing the screen brightness control for awhile? F2 turns up the brightness, may be turned fully down. -
I plugged my iPad Mini Retina in to charge this morning in a UK plug socket using the official out of the box charger.
It charged from 0-27% in roughly 3 hours.
I have come home to find it is not charging at all, when turned off when I plug the powered cable in it does turn on as if it is receiving power but it does not charge.
It is 1 month old and hasn't experienced heavy usage as such.Thanks Sig. The information is here: Anything useful stand out?
