Change battery life from percent to hours

10/19/2010. I have an iBook G4 with the latest Mac OS. How can I change the percent (%) to hours of life, in the top horizontal toolbar? Chuck Y.

Hi Chuck,
Click on the battery symbol, go to "show", then select "time".
Hope that works for you.

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.

I have the 13 inch macbook pro bought in august 2011,the battery life instead of 7 hours lasts only for 3-4 hours why is this so

i was very impressed when i saw the 7 hour battery life of the macbook 13 in the store . but after using the system it only lasted 3-4 hours completely , same was the case for windows 7 pro. all the other functions of my mac are working fine.I buyed the system pin packed in front of me.I questioned the retailer about this but he had no clue what was happenig which caused this.I think this has something to do with china as my mac has been assembled in china and designed by apple californiahttp://computershopper.com/laptops/reviews/apple-macbook-pro-13-inch-2011-versio n these are the specs and the review of the system.but remove the phenominal battery life from the pros.I'm new to apple so please also provide me a location where i can get apple support in Pakistan

The 7 hour battery life is maximum that can be expected with minimal drain, but 3-4 hours either means you are using it very, very hard or the battery is bad. OR the gauge needs calibration, see below.
Turn off WiFi if you are not using it, and dim the display to also save battery power. It also depends on the applications that you are using.
One months is awfully fast for you to lose that much battery time. If the laptop was new, then I would talk to the seller about an exchange, at least exchanging the battery.
Have you tried calibrating the battery? See
http://docs.info.apple.com/article.html?path=Mac/10.6/en/9036.html
for how. Please note, this only calibrates when the MBP charges the battery and resets the calibration of time or percentage of battery charge left. The lithium battery does not have a memory.

Just bought a mid 2012 13 in macbook pro. Battery life is only 3 hours. Thoughts?

Just bought a mid 2012 13 in macbook pro. Battery life is only 3 hours. I was under the impression that it would last 7 hours. This is with normal internet browsing and text editing. my brightness is not all the up and bluetooth is off. Thoughts?

im having the same problems, bought my 13" MacBook Pro last week and the battery is terrible on it, but i googled it and a lot of other people are having the same issues

My ipod has a short battery life from charging too long.

My ipod has a short battery life from charging too long. What can i do about it?

please help

My ipod touch has a short amount of battery life of around two hours, but i installed an app that tells you how much battery life left, it said 4 hours, how come? is my ipod touch battery faulty?

my ipod touch 8gb, ios 4.3.2 has a short amount of battery life of around 2 hours, but i installed an app that tells you the battery life remaining, it said 4 hours, how come? is my ipod touch battery faulty

Some useful info would be:
What generation is it?
How old is it?
If it's older than the 3rd generation, then the battery may have run its course (or iOS 4.3 is taking a toll on the battery).
If not, then you might have some issues leaving the wi-fi on and fetching data as well as running apps in the background that abuse location services and notification. Make sure those are off, or only running when necessary. If you see a small arrow in the top right corner (that isn't the music "Play" arrow), then you are currently running a location based service that can drain battery.
Also check your brightness settings, these can really pull battery life.

IOS 5.0.1 increased battery life from 2 days to 3

I installed the new software on Friday night from a wired connection to the computer. The download and install took around 15 minutes. before the install I could go two days with out a charge. My phone was fully charged on Friday night at 10:00pm. Today is Monday at 8:41am and I still have 50% battery left. I have sent hundredes of text messages, stream hours of pandora, and watch multiple you tube videos. The only two things that I monitor are Wi-Fi when I'm away from home and closing apps. I also always drain my battery life to 1% before charging. If any one wants my setting to try just let me know.

After two days trying out the problem with my iPhone 4s battery - I had "reset all setting", set up WiFi again and disable all location completely, change the notification list. My Gmail account setting to push to off and manually get the emails. iCloud switch tooff.
I had drain the battery completely until iPhone is dead as requested - I had it off for about ten minutes before re charge fully for overnight. I noticed battery had drain rapidly during day if I use messages and emails.
The next day I had re-charged fully to 100%, then plugged it out and I had left it on stand by before I go bed. The following morning I noticed iphone 4S battery down to 84% the same.
It hadn’t makes any differences or am I missing something…

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
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.

MBA 2014 giving battery life of 4-6 hours.

Hi all
I recently purchased MBA 13 inch 2014 1.4ghz 128 gb. 4GB RAM
The battery life of this product is just around 4-6 hours with my usage. My usage is pretty normal the mail app, google chrome/safari, dropbox for 80-90% of the time. I have installed parallels on my machine with windows 8.1 and use it in aggregate for 35-40 minutes in a day and when not using parallels or windows i QUIT the application.
I called up Apple care centre and they advised me to download SMC 2.8 version but when i try to install it says it is already installed.
but when i check system report it says SMC version 2.13f9 only.
I am really frustrated cause of this battery problem I hope that there is a solution to this, as battery life was the only reason i opted to buy this.
Thanks in advance.
Regards

I had the same problem for a week on my Q10. I was extremely frustrated as I couldn't get any advice from Blackberry and the best advice on this forum suggested a "security wipe". I reluctantly decided to go ahead and do that. I first tried to back the phone up. I had to update the BB Link software on my PC and then was able to do the backup. I started to download the software suggested here (which takes 5 hrs unless you pay for it) and then realised the phone seemed to be OK again. Since then it lasted 48hrs and today is only down to 88% after 9hrs.
My problem was mainly that Standby was using 50% of the battery & Androd Player 15%. Both are now under 2%.
Your phone may have a different problem so if you've downloaded the latest BB LInk and done a backup with no luck then all I can say is good luck!

Ipad 2 battery life drain 10% by hour after 5.1

Hello, my name is Martin Vila.
I posted about this same issue a few weeks ago hopping that apple will give an update about 5.1 IOS for Ipad 2 but becouse I need my Ipad for dental school almost everyday i went and search a solution for my poor battery life. After upgrading to 5.1 my Ipad is almost useless with a battery life of 3 hours only with WIFI (this only happen hours after I update to 5.1) So i been searching on the web and I have found a few posts about this, but they are not confirm if this is an 100% solution, they say if i restored my Ipad from scratch using Itunes player my IOS will redownload and the battery will be ok ones again, so is this true, has anybody had this same problem before and had try this solution?, also if I restored my Ipad and I backup with Icloud my Ipad will be with the same apps and contents? I only care for "The skeleton system pro" app because I have a lot of notes in there.
PS: Sorry for my bad grammar, but english is my second language, greetings from Peru

Suggest you recalibrate the battery. See link below.
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%.
How to Calibrate Your Mac, iPhone, or iPad Battery
http://www.macblend.com/how-to-calibrate-your-mac-iphone-or-ipad-battery/
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.

Has anyone noticed a big drop in battery life from the iPhone 4 to the iPhone 4s?

In the 36 hours that I've had the iPhone 4s, the battery life is much worse than the iPhone 4. I'd like to hear if anyone else has experienced this as well.

iOS5 has removed the option to turn off just the 3G and have only 2G/Edge and WiFi. I used to do that routinely because I got much more reliable cell coverage in hilly San Francisco and it extended battery life between charges significantly. I only turned on 3G if I wanted to use the web while I was away from wifi or while on a call. The fact they removed this choice seems to have caught both Apple and AT&T staff by total surprise.
This is a problem in the UK as well as in the US and it isn't not carrier specific. It seems to be part of the iOS 5. I most certainly had it with my iPhone 4 and with iOS 4xx.
While the phone will revert to 2G if it thinks it needs to, that isn't good enough. I can't go a whole day (even half a day!) even on mostly standby. I've taken to turning off WiFi when I'm away from it because I can't turn off the 3G. I realize Siri won't work on 2G and maybe that is what has driven it-Apple's special, incredible new feature but if my phone has a dead battery it won't matter anyway.
Spread the news. Complain. We need to get this option back!

Battery life is only few hours since 5 days

Hi,
One of my colleague and I have some problem with the battery life since 4 or 5 days. After 6 or 7 hours without call or extra activity, the battery is empty. We don't know why. We have something like 8 Bold 9700 in the company and only two have this behaviour since 4 or 5 days.
I have updated the system with the latest version, but no changes.
If you have an idea or a solution, you are welcome
Regards
Franck

Hello Franck
In addition to what Bill said, you may also consider the location where the phone was since you mentioned that the problem happened the same day for two phones. If those phone happen to exert more effort to get coverage to sustain themselves, they lose more battery life faster.
You may check one of the threads I posted here.

Battery Life down to 1 hour

I just got my Mac Book Pro in March, and intially the battery life was amazing. Now the battery life is down to about an hour to a hour and half. This I know is not normal for a Mac. What is giong on?

I talked to Apple's Customer Service and they said that it is my fault that my iPod has broken and that it is also my fault I did not purchase the $70 extended warranty...BS. They also said that unless I have other Apple products I cannot receive a coupon or a gift card.

After reseting Ipod touch my battery life is only an hour

I had to reset my ipod and now my battery life is extremely short. Anything I can do?

You may have stuff running that you don't know you hve running. Such as notifications default to on, so you may have a bunch of stuff going out and reaching for info that you don't realize is running. So you can look there, and also look at your mail. If it's set to fetch mails or to push. if it's on push, then y our iPad is reacing out to get the mail all the time.
So try turning stuff off. but if the battery is still not acting like you want it to, make an appointment at your local apple store and have them run diagnostics on it, just to make sure. they might also be able to give you some tips or find what's draining your power.
