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.

My new iPod nano does not get the battery life that is advertised

Help me my iPod nano does not get the battery life that is advertised

Which battery life are you referring to? Apple's website states the iPod Nano 6th Gen will get "up to 24 hours of music playback when fully charged". There are going to be a lot of things that can change that. Are you using the stopwatch or the count down timer a lot? Are you using the FM radio a lot? Any accessories that you are using with the iPod? These will all have an effect on your battery life.

How does 2nd generation mini get better battery life?

Hey all
Just wondering basically if the 1st generation ipod mini can have the battery changed or something so as to give it the claimed 18 hour battery life of the 2nd generation rather than just 8 hours

You can measure and compare battery 'life' by looking at the capacity in mAh. As the Mini battery is 400mAh, you can expect somewhat proportional run-time increases as you get higher capacity.
See: http://pdasmart.com/products/AP39ipodpartscentermini.htm as an example. This is the largest that I have seen, but I'm not really looking at this time. Do a Google search for more like this.

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?

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.

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? :-)

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.

Macbook Air is not giving me 12 hours battery life!

I bought my Macbook Air 13" 8GB I5 a week ago and from the beginning it didn't gave me the battery life I was expecting to get.
I only used safari and itunes so I think this isn't normall. I already read much complaints about this issue but not yet a clear answer.
Is it just a problem that's gonna be solved with the next upgrade or should I take it back to the store?
I find this realy annoying and hope to get an answer!

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!

Not getting full battery charge

I've had my nano since December, recharge it by plugging it into my computer's USB port. I haven't changed anything, unplugged anything, etc. The battery has never lasted as long as advertised (more like 9 hours) but this week it's not even getting fully charged overnight. The battery icon shows the plug as if it's charging, and never gets to the lightning bolt. I've unplugged it and used it, sure enough it's not fully charged and now the battery lasts about 4 hours.
I updated my iPod software and iTunes software in January (less than a month after receiving the unit!). Do I need another update? It shouldn't be worn out, I've only charged the unit maybe 20 times. Anyone else having this problem?
Windows XP

That's kind of messed up, I've had my nano since october or november, don't remember which month I purchased it, I'm pretty sure it was october. Here is what I do to conserve battery life on my nano:
1. Use the backlight when you are in dark rooms and stuff, if in a well lighted room then there is no need for the backlight, this means turn the back light off completely.
2. Don't have the volume turned up as this requires alot of battery, if you have a problem with surrounding noise than get yourself a pair of $14.00 Koss noise reduction increased bass earbuds at your local Target, by the way these are great because they they use a memory foam type solution to ensure a great fit every time and they are also priced well and they reduce noise well.
3. Convert all your music to AAC format, this also helps
4. Make sure your nano's software is update, this tremendously helps, because apple does release software updates that will improve your batteries performance.
5. When you go to sleep let your nano charge overnight, this might be your problem.
If all else fails send it in to Apple.

Getting good battery life

Hey guys, so I have a new macbook pro 15 inch, and I am wondering if I should do somethign first to it maybe the calibaration to get good batter life? I just charged it all night, and I am in class, and just doing webbrowsing, it is saying that I only have 3 hours left? Not sure why, but that number should be higher right? the brightness is on low and everything.

The time Apple quotes for use on battery power requires that Airport, bluetooth are turned off, no externals are connected, no cd in the drive, etc. As soon as you use these or headphones, mouse, etc your available time will be lessened considerably. Tasks that you have it doing can also affect performance, especially any that involve much reference to the internal drive or heavy processing.
Calibration is primarily to have more accurate stats. It sets the original actual capacity of the battery and enables calculations & comparisons to be more accurate. I'm not sure that it actually improves the life of the battery, rather it enables a more accurate estimate of condition & performance to be given.

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.

After 4.2.1 Dropped/Choppy calls and poor signal / Gets hot / Battery Life is bad when talking

What is this APPLE? I can see the Iphone 3G is old and no more support but atleast make a working OS and then go out on a high note. Instead of leaving us hanging with a broken phone. Not just me , scores of others have these very same symptoms. Also I wish there was a way to go back to an older OS , one that worked %100 for my phone.
Dropped/Choppy calls
Get REAL warm
Batterylife is crap only when talking
Never had these problems before 4.2.1 , it's like night and day. I was hooked on the Iphone since I bought this 3G brand new and its ease of use but Ill tell you one thing....
Im not under contract right now with anyone
I WILL NOT be buying a phone/contract with APPLE as long as 4.2.1 is left in our "lap".
I WILL be buying another smartphone if this is what we are left with. I was going to treat myself and buy the 5G with a contract to make it cheaper but as of now
Im feeling "used" by APPLE and not going to take it.
I know some might come here and post ..
"Me and others aren't effected by 4.2.1 , must be your phone"
BS! It was night and day when I downloaded/installed 4.2.1. This is NOT my Phone and IS the firmware. And my friend that is a phone nut said he didn't download 4.2.1 because of all the problems he was hearing about it, I should have done research. He said the biggest hit was the 3G and he can't belive I installed it.
APPLE DO YOUR JOB AND FIX THIS. MAKE 4.2.2 ATLEAST AND FIX THESE PROBLEMS!! IF NOT THEN WE MUST PART WAYS.
                                                            DamianJP

Cool
Did the new device and didn't do a restore from backup. Grabbed all my contacts from windows contacts saved list. So only thing the same on the phone was the same 4.2.1 that stays in there. Still bad signal and battery life, although the battery problem might be the age of the battery since its the same battery that came with the 3G.
I did the Field Test mode program
http://socialtimes.com/find-your-iphones-signal-strength-using-the-hidden-field- test-mode_b4690
- Open the iPhone’s dialer keypad
- Enter *3001#12345#*
- Press the Call button
-80 to -70 dBm: Reasonably strong signal
-107 to -90 dBm: Weak signal
-113 dBM: No serviceable signal
In my house im getting any were from -100dBm to -117dBm ( 1 to 2 bars with 3G)
Outside Im getting -85dBm and up. (2 to 4 bars with 3G)
I have to do more testing to get solid numbers though. I got almost full bars all the time if I switched to EDGE.
(4 to 5 all the time with EDGE). That makes me think that with the problem in 3G , it's the OS. Since ALOT of people saying that there 3G drops or is bad since 4.2.1.
Now I looked around and I playied with all my settings to insure that my battery should not drain thru improper settings. So I think given this is the original battery , it might be a good time to try and install a new one from here for $17.
http://www.iphonebatteryrepair.com/iPhone-3G-Battery-p/bat-1001.htm
Iv'e opened Iphones before (fixed my friends 3G) after he dropped his and the vibrate/silent button's screw came loose and he could not change it off silent mode and replaced a battery in my other friends 3Gs. SO i feel comfortable in there.
I dont know if the bad battery could be reducing my signal.Ill try the battery cause it's only $17 (Cheap investment) and because my battery life under a load drains it fast. Again I don't know if it's the OS or the age of it.
I was thinking maybe a poor contact/condition of my SIM card could be another possibility. I wonder if and how much a new SIM card from a AT&T provider is. I heard people saying you can get a new one but Ill have to ask my local AT&T dealer.
Although this seemed so odd how it all happened the same night till now RIGHT after the 4.2.1 OS install and all the others people saying the same symptoms.
Ill keep working with it and give you (and others users here) updates in my progress for the people who are in the same "boat" as me.
By the way I haven't tried to make Itunes re download the OS by deleting the file in the directory you gave me above. Ill try that as soon as I post this message.
Also Iv'e noticed that theres a way to download a older version of Firmware OS and put it in a certain directory and use the DFU mode (Deep Firmware Upgrade) on the Iphone to force the Iphone to re install the current version or an older version ( whatever version you download) of firmware. Now Im very worried that this might mess my Iphone up to were it wont even work so I really dont want to try this right now or until I exhaust all my other options. I have to do more research of this method.
Sorry for the long post but I think I kept it faily organized for a easy read, I hope.
                            Thank You Ingo !!

I Have been getting BAD battery life after the ICS UPDATE !! on the DROID RAZAR MAXX have this happen to any one else ??????

i have been getting really bad battery life after install ICS on my droid razar maxx i can only go 1 day and 3 hours where i used to be able to go 2 day easy have this happen to anyone else can someone tell me how i can make my battery life better??????/ and do i need to let my phone go complete dead before fully chargeing it again ??????
before install the ICS update i had 30 percent of battery life remaining so i pluged it in and let charged for a little bit while it updated my phone and ever thing after it updated i unplug my phone and started playing on my phone to see what ICS was all about but when it got to 15 and said " connect to your changer so i did !!!!! should i haved let my phone going complete dead since i unplug without it fully changer or does it matter ?????????????? if someone could please help me !!!!:)

What was your battery reading right after the update when you unplugged the phone? I have never let my Maxx drain further than 20% battery ever before I charge it. Yesterday after the update I also played more with the phone trying to learn the OS, as did most everyone on this forum. Give it a few days of your normal use before you decide your battery life has decreased. I took my phone off charger today at noon, it was 100%, and now it's 80%, with about 30 min talk time, and mostly standby. that's about normal batt life for me, maybe a little better than before the update. I'm still going to watch it for a few days before I make a conclusion about battery life.

New iPod Nano... How to get best battery life?

Hi there. I just got a new iPod Nano. What is the best way to get the best battery life? I know there is a partial charge on the iPod already (it turns on and the batter meter shows it approx. 2/3 full). Should I plug it in a fully charge it first? Should I put some songs on it and fully drain the battery and then fully charge the battery and then fully drain it again?
How can I get the best battery life out of it? Are there any Apple documents to explain how?
Thanks,

There are documents, there are theories, there is folklore, there are opinions. I'll give you my opinions (but they are based on a fair amount of research and experience). The type of battery used in the iPod has a useful lifespan of between 3 to 5 years, and can be completely charged/discharged between 300 to 500 times. If you charge it totally, discharge 1/2, charge to full again, and discharge 1/2, this only counts as 1 total discharge, so don't worry about running it all the way down, etc.
You can leave it plugged in all the time if you want, because it's smart enough to stop charging when it's full. You can recharge whenever you want based on what I stated above.
Is there any advantage to running it all the way down and back up? There is an Apple KB document that suggests getting "exercise" like this is good for the battery on a monthly basis. Several people here swear by that, but when I have asked, the only source they usually give is the Apple article, or things based on that article. I've not seen this claim independently stated.
What is true is that you may need to let it run all the way down occasionally to keep the battery meter calibrated, but this has nothing to do with the actual condition or health of the battery.
Also, it's bad to let the battery run all the way down and then remain that way for a long period of time. Plus, if you plan to store this type of battery for an extended period (i.e. for a month or more) then the optimum charge seems to be around 60% of full, although it would gradually trickle down from that over time. Also, don't get it too hot as that's bad for it.
Is that way more than you wanted to know?

Turn off Wi-Fi, get more battery life

How big of an increase will there be in battery life on the touch if I have the Wi-Fi turned off?
Prof.

You will probably get some improvement, although if you aren't using it then it probably won't be spectacular.
Saw some posts here saying you can get 7 hours of battery using Safari/WiFi.
I get about 2 hours surfing the Discussions.

Not getting 10 hour battery life.
