Ideal Settings for 7 hour Battery Life

I just wanted to know what the ideal settings would be for a 15" MBP Mid 2009 Unibody to reach the 7 hour battery life as advertised.

Apple states that the Better Battery Life setting was used, and +"The wireless productivity test measures battery life by wirelessly browsing various websites and editing text in a word processing document with display brightness set to 50%."+
You can bet that the 'various websites' chosen were simple ones (no Flash animation, etc.). Also, 'editing text in a word processing document' with the autosave feature turned off will allow the HDD to spin down, saving power.
So, what you'd need to do to get 7 hours on battery is set the brightness to 50% or less and do only +really simple+ tasks on your MBP. IMO, the 7 hr estimate isn't 'real world', it's marketing.

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 in the UK. The charger has stopped working. Which model and voltage do I need please?

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? :-)

Not getting 10 hour battery life.

I remember reading it had to be at half the capacity of the uh, ..screen..light, lol. Am I missing something else? Mine's just a smidge below half, and it only has about a 4 and a half hour battery life. Are there other settings that I need to tone down that I'm not aware of? I bought my MBP this year.

Hi
Can you let me know how did you solve the battery problems. I was happy to have a mac with 8-9 hrs running time when compared to my earlier iBookG4 which gave 4.5 hrs till its late days.
I am having a MBP that is just 1 month old and under use since a week.
i am deeply worried when it shows 3.5 hrs after full charge. deeply disappointed.
Do lend me some helping hand.

VMware Fusion Ideal Settings for Best performance

Can someone please help with the ideal settings for VMware Fusion on mac for best performance.
My Machine Details
MacBook Pro (13-inch Late 2011), Mac OS X (10.7.3)
Processor : 2.8 GHz Intel Core
Memory : 16 GB 1333 MHz DDR3
Storage : 750 GB SATA Disk
Graphics : Intel HD Graphics 3000 512 MB
Am using VMware Fusion Version 4.1.2
At Present the resources I have allocated for VMFusion are
Processor : 1 Core
Memory : 4 GB
Thanks
Brij

VMware Fusion doesn't slow down the Mac just because having it installed. You have 16 GB of memory in the computer and you assigned 4 GB for the virtual machine you have, so you shouldn't have any memory problem. Also, your Mac has got a great processor that run virtual machines without any problem.
If you feel your Mac slow while running the virtual machine, just reduce the amount of memory assigned to the virtual machine, depending on the operating system you have in the virtual machine. For example, I recommend 2 GB or more for Windows 7, and you can run Linux virtualized assigning only 512 MB of memory

New iBook with 4 hour battery life? should I ask for a replacement?

after about two months of use, my iBook is only getting 4 hours of battery life, I've done everthing right with it, per apple's own instructions.
does anyone know what their policy is? can I go to a store and get it replaced, or am I stuck with it?
thanks hope somone knows what's up with it, I would have liked my 6 hours as promised.

Please read the terms of use here about discussing policy on the link on the right hand side.
4 hours is actually quite normal. There is a part of Apple's website which explains how to optimize battery life:
http://www.apple.com/batteries/notebooks.html
If after optimizing your battery you aren't getting satisfactory results, you can certainly try to take it to a service center to see if they will replace the battery to see if it is the battery or the power management of the computer.
I'd only worry about the battery though if you were consistantly only getting about 1.5 hours or less out of it.
6 hours was never "promised". Read this page carefully:
http://www.apple.com/ibook/specs.html
"Up to 6 hours." If it had said "Always 6 hours and if not, we'll warranty replacement" I'd say that would be a promise. But it does not.

Fix for iPhone Battery Life

Hi, I have done this with IOS 5 through 6 and it works.
I have done this serveral times with my phone, as battery life decreases. I have not figured out what is the original cause of my battery problems, but every now and again, something starts to dain my battery at a rappid rate, in an hour or two. This is the fix to reset it.
1 - Back up you phone to iTunes
2 - Go into the settings under General and at the bottom sellect Reset and reset your iPhone erassing all data.
3 - Once it resets and shows you the default "out of the box" screan, power it off
4 - Recharge it FULLY.... I leave it over night.
5 - Power it on again
6 - Restore your settings via iTunes.
7 - Your done
In my experiance, if you skip any of the steps, like not powering off when your recharge or not recharging fully, will result in it still draining quickly.
Hope this works for you.

Thanks JJT2122 !
I added your fix to the list of available fixes that improve iPhone battery life

Sub 1 hour battery life (9 cell) on Windows 8.1

Hi all,
A few months ago I installed Windows 8.1 on my T400 (Type 6475) and ever since have experienced abysmal battery life. I have a 9 cell battery in good condition that gave me at least 5 hours of moderate usage when I was running Windows 7 on this machine. Now I'm lucky to get an hour running Windows 8.1 which just isn't really viable. I've checked the battery on my backup T61 running Windows 7 and still achive perfectly acceptable lifespan with that - so the battery's not the problem.
This is my second clean reinstall of Windows 8.1. I've checked all of my drivers are up to date and are Windows 8.1 versions where they exist. My T400 doesn't have switchable graphics so I don't think it's that causing the issue. Bluetooth is off. I've got Power Manager 6.32 installed and working flawlessly. All settings are as they were when I was running Windows 7 (optimised for battery life when off of AC).
Before I give up on Windows 8.1 and return to Windows 7 is there anything else I've missed?Is there any way I can check what's using the battery?
I'm not a massive tech-head so be gentle if possible...
Thanks in advance!

Hi,
Welcome to Lenovo Community Forums!
I’m sorry to hear that you are getting a poor battery backup in your Lenovo ThinkPad T400 after upgrading to Windows 8.1.
May I know which power plan you are using in your system?

After reset to factory settings, still terrible battery life.

My iPhone 4S 64 only six weeks old, but recently my battery life has gone from fair to totally unacceptable. After taking all the steps to minimize battery drain and then going through the process of backing up, I then restored the iPhone to factory settings. No change at all. For example, right now it is sitting without being used at all (yes, 3G and wi-fi are both on)*, and after 3 hours and 46 minutes since full charge (using Battery Doctor) the batery stands at 56% !
I a aware that iOS 5.0.1 is not kind to battery life, but I have had four iPhones and have developed a fairly good sense of what battery life I can usually expect from the way I typically use my iPhone, but this really has me stumped. Can anyone offer any suggestions? Many thanks in advance. pah

I had a similar instance where the battery drained by about 25% overnight. I had to "Reset all settings" and setup the phone as a new phone. After you restored to factory settings did you choose to setup the phone as new or did you restore from backup? I didn't choose to restore from backup because there wasn't a need to.

What are the ideal settings for my TC with Shaw's Cisco DPC3825 router/modem

My old 2nd Gen Time Capsule crapped out and now I am about to set up my new 2TB TC. My provider is Shaw Communications and they have upgraded me to their Broadband 100 Mbps service. This came with a new modem/router combo made by Cisco and is model DPC3825. Before I start plugging things in I'd like to know what are the ideal settings such that I gain the most of the BB100 service. Should I be setting the Cisco modem/router to Bridge mode or the TC? Should I have Shaw disable anything? Any insight is greatly appreciated.

Unless you specifically need to have the TC perform as the main router for your network, life will be a lot easier if you configure the TC to operate in Bridge Mode.
Whether the Cisco modem/router or gateway can possibly be configured to act as a simple bridge mode modem is one thing to consider.
Whether Shaw would support you in the event of any connection difficulties with the modem/router configured this way is another.
Since Shaw is your provider, it might make sense to talk with them about best practice as far as configuring the DPC3825.
Once you have that information in hand, you will then have the answer on how best to configure the TC.....which will very likely be in Bridge Mode.

When/how to charge the iPhone for optimal battery life?

I have an iPhone 3G 8GB. I was just wondering what the best way to go about charging the iPhone is, in order to optimise the battery life?
Should you wait until the iPhone is really flat/ low battery and then charge it up full, or are smaller and more frequent 'shallow' charges healthier?
I also heard somewhere that every couple of months or so it is a good idea to let the battery run completely dead and then charge it up, in order to calibrate it or something... but that doing this too often could be detrimental.
Any help/ advice would be greatly appreciated! I don't know if I should let my iPhone run really low before charging it or if smaller more frequent chargers are the way to go.
Thanks!

Thanks! I did read over that and have taken the steps mentioned and fiddled around with settings of my phone to optimise use. I was just wondering if anyone else had anything else to add about charging habits specifically and what works best... I think mainly I'm just being paranoid about my phone dying prematurely since it's the first time I've owned such an expensive gadget!
Also, can you overcharge it? Is it bad to leave it on the charger overnight? I've done some searching in other threads/ webpages and there seems to be some discrepancies but for the most part people seem to think that it will be fine?

Optimum settings to maximize battery life???

I'm running firmware rev 1.1.1 on my iPhone and battery life after a full charge does not seem as good lately (purchsed Aug 23rd).
I've been emailing the support person at the local Apple Store and he mentioned "non-optimal settings that can be decreasing battery life"...anyone know what the optimal settings are? Anything official from Apple?
Two recent tests I have done indicate that battery life does not seem to be optimal for this unit. The Usage and Standby numbers below were provided by the iPhone under Settings -> Usage. These tests were done with WiFi on, email set to manual, and charged from the Apple Power Adapter.
Oct 12 - Full Charge
Clock time Usage Standby Battery
4:28 PM 38 min 9 hr 26 min about 1/4
Oct 13 - Full Charge
Clock time Usage Standby Battery
9:21 AM 7 min 9 hr 38 min less than 1/2
It appears that even with no use of the iPhone, a charge would be required each day, and with more frequent use, additional charging would be needed.
Thanks in advance for any help.

I leave WiFi off unless I am actually using it, which can be a pain b/c it takes extra steps to get it turned back on and have the phone search for a hotspot when you need it. But Wifi definitely kills the battery alot faster so i think that the trade off is worth it. I would also keep bluetooth off if you will not be using it. I use it in the car and with my headset so this is difficult for me, but it does drain the battery. Lastly, I often keep the brightness setting in the middle; I think that this was how it arrived from Apple.
Other than those things, I'm not sure what else that you can do. If you are needing to recharge your phone daily, with all of the above things implemented, and with little actual use of the phone,I would definitely get it checked because something is definitely wrong.

Optimal settings that maximize battery life?

For those of you who could get 12+ hours of play-time, how have you set up your nano?
I could not even get my nano to play for more than 4 hours and I am thinking that I might not have it set up properly.
Any comments and/or tips will be appreciated.

Chan Chen,
Was this your first use? Try charging and the running completely down and then charging again. It takes a few cycles before the battery reaches it's maximum potential. Visit this site for more tips on increasing battery life:

My battery fluctuates, is it truly a 7 hour battery life?

Ok,
Apple "claims that the new unibody MacBook Pro's have a battery life of 8 hours on the 17" and 7 hours on the 15" I have the 15 and when I go portable, I notice that my time on the battery icon in the top toolbar fluctuates. One second it could be on 3:45 and then the next minute it could be on 6:59 and then the next 1:45. Is this an apple glitch or it is something with my laptop?

Retired Engineer wrote:
They did not say the battery life is 7 hours, they said it is UP TO 7 hours. You will only achieve that with a very light processing load and the screen turned down to one notch above off and bluetooth and wireless turned off.
That is inaccurate. Apple documents "up to 7 hours wireless productivity test" on the MacBook Pro's Tech Specs page as follows:
The wireless productivity test measures battery life by wirelessly browsing various websites and editing text in a word processing document with display brightness set to 50%.
So it's 50% brightness, not zero, and wireless is turned on, not off. Apple is pursuing more realistic battery life estimates than in years past, and also more realistic than many other companies advertise.
Is this true? Is Apple's test realistic? Well, some independent reviewers, with their own tests, have achieved over eight hours. The linked reviewer was not the only one, but I'm too lazy to Google the rest.
That said, it's true that battery life is completely dependent on settings and power drain. If you're editing Photoshop or video, no way will you get seven hours. Under a heavy CPU, disk, or video card load, you might see 2-4 hours.

Which is better for the battery life?

Should I keep the charger plugged in constantly or use up all the battery life and charge only when the battery life is near 0% and charge until full?
I want to keep the battery life as long as possible. Thank you!
