Checking battery performance on E6

I'm checking the battery of my E6 with Energy Profiler because until now I've had a disappointing performance.
I've read at http://www.developer.nokia.com/Resources/Tools_and_downloads/Other/Nokia_Energy_Profiler/Quick_start... that "As the battery discharges, its voltage level decreases from roughly 4.2V to 3V until the phone switches itself off".
Right now I have 1 bar left and Energy Profiler is indicating 3,65V (and so is Battery Info).
Are the instructions wrong about the the 3V minimum (or for other types of batteries) or the last bar is worth 0,6V?

try turning off all the eye-candy on Vista (that means turn off Aero), it will save your battery, it's because it's also making your CPU/GPU work harder.

Battery performance reduced abruptly

I just bought my MBP 15" with a 2.8 GHz intel core i7 processor, 8 gb in ram, and 500 gb hard drive in december 2010 (6 months ago) and it worked perfectly until after a couple of months later. I decided to restore it and install windows 7 with bootcamp, but after restoring OSX, battery life performance was all of a sudden reduced abruptly. It only had gone about 80 cycles and now battery was not lasting more than 4-5 hours at 5 %. The battery icon on finder went totally crazy, going from 10 hours to 1 in just a second no matter the charge percentage; every time i checked it, it showed a different time. I calibrated it at least 3 times before deciding to go to a service center.
I took it to an authorized apple service establishment to claim my applecare plan. Neither the battery nor the MBP showed any problems and apple would only blame it on usage, but the service guy did detect something wrong, so he kept trying and after A LOT of scans and tests, battery finally showed a problem, which allowed him to order a replacement battery.
When i got my device back, I started noticing the problem was not really fixed, so i kept monitoring the battery performance only to find it was still going wrong. This time I did not bootcamp windows. I finally convinced myself that i was being too tough with my MBP after a few calibrations until battery started to go even crazier than the first time, plus this time, also the hard drive was showing problems since it would take literally about 10 minutes to start and it would never turn off unless I forced it to do so. I took it again to the service station where they ran test and got me a new battery replacement and a new hard drive.
This is my third battery in less than 6 months, and now I am starting to detect those same symptoms in the battery performance that in the past. This time i decided to take it to technical service before it totally crashed like past times, but since it was a different guy who checked it, he did not detect anything and did nothing to it. I am pretty sure my MBP is totally sick since this time, with only 20 cycles, battery is lasting from 1 to 4.5 hours with minimum usage, but no one seems to know whats wrong with it. I tried asking for a whole MBP new replacement with my applecare extended warranty, but they just keep blaming it to the usage i give to my device (which by the ways has been kept to minimum since the last time I got it back)
Please any help from anyone? I am kind of desperate and disappointed at this point.

I'd be concerned that it might be some other controller component or a bad logic board if other parts are repeated failing, maybe something else is causing them to fail.
I'm probably flirting with the terms of use here, but I'd recommend trying out small dog electronics in vermont for your repair (google them, don't want to post a link to risk losing the post before you get to see it). I get no compensation from them, I'm just a fan of their work. they're very thorough and if you explain the whole problem and what you've done before, they'll go above and beyond to test and retest after they do work to confirm they've fixed things. they have a mail-in service option too so it doesn't matter where you live. if you haven't resolved this yet, I'd check them out. as an independent apple reseller and repair center, they seem to be more of a consumer advocate than just a fixit genius bar looking to resolve an immediate problem and move on to the next. that said, I've had great experiences with my local genius bars. I'm just saying that maybe someone like small dog would have a better chance to test, fix, and re-test over some time or a few days to confirm a fix before giving it back. I'm thinking it's more than a battery if other components aren't behaving as well. I'm not a tech so I can't suggest what to try, only where I'd try next and expect good results.

10.6.4 shorten my battery performance

After upgrade to 10.6.4, I found the battery performance does not perform as before.
It used to have 9hrs (displayed in menu bar) that I can work with.
However, after 10.6.4, the battery indicator shows 7hrs only at same working environment (safari, iwork, msn, endnote, and some small research software, and 50% screen brightness).
Is this my self-suspicion or it is the problem comes with 10.6.4?

FWIW, I have not noticed much difference in battery life with my white 2008 MacBook after updating it to 10.6.4.
I don't usually have the menu bar icon set to display time remaining because as noted by another poster it is just an estimate that changes often depending on what I'm doing. For example, with a fully charged battery, I see about a 5 ½ hour estimate with no apps running but as soon as I start Hulu Desktop & connect to its servers over Airport, the estimate almost immediately drops to about 3 hours & declines from there. But if I quit the app, the estimate jumps back up. If I then let display sleep kick in for a minute or two & then wake the screen, I immediately but briefly see an estimate of over 7 hours! For that reason, I leave the icon set to display percent of battery power remaining.
This behavior has been about the same since I got the MB with Leopard installed & remained so through all versions of Snow Leopard, 10.6.4 included.
One thing to check is your battery's condition. (As described in Mac OS X 10.6 Help: Battery conditions, this is very easy to do with Snow Leopard.) If it doesn't say "Normal" it may need service or replacement.
Another thing to check is if all your power related system preferences are still set to what they were before applying the update. Sometimes an update will reset one or more of them to a default or unexpected value.
Also, it might help to share battery info like charge cycle count, a rough indicator of how much the battery has been used & its remaining capacity to hold a charge. See Determining Battery Cycle Count for more about that. FWIW, my 2008 MacBook isn't used much & has only gone through 58 charge cycles. As recommended in Apple - Batteries - Notebooks, I occasionally let it discharge completely.

What does Apple mean by "For best battery performance, leave your device connected to a power source until the restore is complete."

I just recently returned an IPad air and exchanged it for another. I first set up this new one as a new IPad but then deleted all content and settings right away (since I wasn't getting the progress I had made in apps and games) in order to restore it from my previous IPad Air. I then checked after on how to backup via icloud and saw this line under the subtitle of how to restore from a backup, "For best battery performance, leave your device connected to a power source until the restore is complete." What does Apple mean by "for best battery performance"? Im just a bit worried of issues.
p.s. And yes I did have it connected to the power. And the ios is the default ios for new IPad Airs.

Welcome to the Apple Community.
It only means you should restore whilst it is connected to a power supply, so that your battery doesn't go flat during the process.

IPhone 4S Poor Battery Performance SOLVED!!

iPhone 4S Poor Battery Performance SOLVED!!
I found the issue with the iPhone 4S battery performance.
I bought 2 iPhone 4S models on the first day. One for my wife and one for me. The strange thing was that mine would kill the battery in 4-6 hours and ran VERY WARM to the touch. My wife's phone worked great. It was cold to the touch. She would forget to charge it at night... and the battery performance was great... even better than our prior 3GS models.
What was the difference? I have my phone connected to Exchange for my corporate email. But exchange is not exactly the problem. The issue is in Notification Center. For some reason, I had hundreds of calendar reminders that kept refreshing on notification center. Furthermore, the reminders would flicker between the time remaining and the start time for the event at such a fast rate that it could not be read... (clearly a bug)
What is the solution? Go to Settings>Notifications>Calendar and disable Notification Center. You can still have the "alert style" set to Banners, or Alerts and you will still receive notices about your events, but it will not BUILD a summary in the Notification Center drop down screen. This is where the BUG exists. [Oddly, this does not affect my iPad 2, but is an issue for iOS 5 on the iPhone (different builds, maybe?)]
So, it appears that Notification Center has an endless loop in collecting the calendar events from Exchange and this is burning up our 4S batteries. Once you stop the madness from Notification Center, your iPhone 4S will perform as advertised.
Enjoy!

Battery Performance

Hi all...how has battery performance been? Got my phone yesterday and charged it overnight. Barely used it today and it drained very fast.
I have turned off wi-fi...to see if that did anything but any idea how things are going?

Joe Raymond wrote:
I don't view it as "3G Sometimes". I've knocked my device down to Edge and have taken the stance of "3G when I need it". If it's truly a phone then for the majority of the day it should either be glued to your hip or our ear. If you want to use it as a substitute for your laptop then you should expect battery life to be like one.
Wellllll...not quite.
It's not just a phone, it's a phone and an iPod at the very least, and it's certainly marketed as more than just a phone. It's marketed as a phone, an ipod, an email checker and a web surfer.
My first take on your "if you're going to substitute it for your laptop then you should expect battery life to be like one" was "yeah, that makes sense," but on second thought, I disagree.
My 15-inch MacBook Pro laptop has what, 16x as large a screen? 5x the CPU clock cycles, and twice as many processors. My laptop has 20x the storage space on the disk. My laptop runs dozens of programs simultaneously without needeing to put them to sleep when I switch to another. My laptop has WiFi and a CDMA modem in it, and I can get 2-2.5 hours on it off the grid with a few power management tricks like dimming the screen and turning off WiFi even while connected to the CDMA network.
Given the significantly smaller size in all features and the supposed power-consumption friendly design of the iPhone, I think it's reasonable to expect that I can do laptop-like features on it with an expectation of greater than laptop-like battery life.

Battery Health: Check Battery

Mid-2010 Macbook Pro. I use the app Watts to alert me as to when I need to condition the internal battery, which is done on a monthly basis. Just yesterday, right before the regularly scheduled monthly conditioning reminder was seen, I happened to click on the battery icon in the menu bar. In the drop down window was a yellow triangle with an exclamation point in it along with the words "Battery Health: Check Battery". At first I didn't think much about it, as soon afterwards the Watts app kicked in to remind me of the upcoming conditioning.
The conditioning has been done as per Watts' suggestion but the yellow triangle is still there.
Clicking on it brought me to an Apple support page (HT3782) for the battery menu extra bar, where the exact wording of the alert on my Macbook is not seen nor mentioned. Just as a precaution I've followed the steps suggested *prior* to resetting the SMC (sleep, restart, shutdown). The yellow triangle remains.
What's a Macbook Pro owner to do at this point?

Current Battery Cycle count is 538. Full charge capacity (mAh): 4273.
The laptop was purchased in October 2010 with Apple Care. What puzzled me was not being able to verify the meaning of the particular message in the battery extra menu bar.
If in fact this installed battery is at its expected life's end and a replacement is warranted, it's a blessing in disguise, as it has never performed anywhere near its nominal estimated life: despite efforts on my part to monitor screen brightness, turn BlueTooth off, quit unused applications and turn WiFi off when connected to Ethernet I've never been able to get more than 5 hours' use out of a fully-charged battery.
Thanks, leroydouglas and mende1 for the prompt replies and suggestions!

Has anyone noticed a decrease in battery performance?

Has anyone noticed a decrease in battery performance? Is this covered under the Apple Care Warranty?

Hi Dominick,
The charge capacity is definitely inline with manufacturer's specifications. I will say that the charge cycle is a little high, though.
129 cycles / 8 months = 16 cycles (per month)
That's about one every other day. It sounds like you use the machine frequently for short periods of time. Is this machine at home or in an office? Or are you mobile with it to where you don't have access to A/C power or can't be "tied down" to a specific location for any period of time?
There's no reason to run the machine off of battery power if it's sitting on your desk. Matter of fact, I probably use my "portable" at my desk more than I use it was a portable. You could be racking up unnecessary cycles otherwise. On one of my machines it's plugged into power 98% of the time, I'll run it down and give it a full recharge once a month per Apple's recommendations.
As AussieDJ recommended, check Activity Monitor to see if anything is consuming unnecessary amounts of CPU usage.
If this is an 11" MBA, approximately 4 hours of run time is well within reason (based on usage), but that's a little low if this is a 13" MBA. Again usage is important here, web browsers and flash-heavy content consume a surprisingly large amount of battery.
I'd also be curious to see a consecutive usage test versus these 10-30 minute usage intervals throughout the day. Give the machine a full charge, use it as your normal would for a 2-3 hours and see how that goes.

Difference in voltage between Europe-U.S. to blame for battery performance?

I recently bought (September 2010) a MacBook Pro 15" 2.4GHz Intel Core i5 4GB from the U.S. While using it there the battery lasted approximately 8-9 hours. Coming back to Europe (Greece) and charging it here, I noticed that the battery won't last more than 3 hours in every full charge. Can we blame the difference in voltage between the U.S. and Europe for this problem? I still use it in Europe with the Power adapter that I bought in the U.S.

The MagSafe Adapter is rated 110-240 volts and provides everything the battery needs in the USA, Europe and elsewhere, this is not the reason for your battery performance variation but something else that's happening now that wasn't then. Check for any background processes with Activity Monitor to see what's running that could cause extra drain.

Iphone4 battery performance...

hi
im a new user so im just checking iphone 4 battery performance...
To be honest I expected a little bit more from this point of view...
I got a brand new phone and the the first full battery charge lasts 24 hours...
wifi and 3g mode-on but I made only few calls and internet searches...
What's the real standard?
http://www.apple.com/iphone/specs.html

I'm afraid so does Damon. The iPhone has a Lithium-Polymer battery, which does does suffer any of the problems of NiCads or NiMH batteries. You can recharge the battery at any time, regardless of what its current charge is. It is impossible to overcharge it, it's a SMART phone it's sitting in.
A lot of apps are never open:
http://whenwillapple.com/blog/2010/04/19/iphone-os-4-multitasking-explained-agai n/
Why worry about the backlight? Life is too short. I offer you the only iPhone battery rule you will ever need:
If it's flat, charge it until it works. More if you like.

Zen Micro: Poor Battery Performance Even with Firmware Upgr

The Zen Micro's battery life is advertised to last up to 2 hours, but I am only getting approximately 7.5 hours. I have installed the latest firmware v.0.03 upgrade, and fully charged and discharged both batteries at least fi've times each (using the USB and AC adaptors before plutting into outlet). Before the firmware upgrade I was getting just under six hours of battery life. For testing purposes I am using 28kbps MP3 files, volume level 8, no EQ setting, no backlighting, and the headphones that came with the product. Since I have the player sitting on my desk, without being listened to, there's no skipping or forwarding of music tracks. Gi'ven the non-demanding settings, the battery performance is disappointing.
I have contacted tech support and they want me to send in my player for repair or replacement. It seems this issue is prevalent for all Zen Micros and I don't want to send mine in to have it returned all scuffed and scratched and not fixed (or get some grimy second-hand, refurbished model instead).
So I want to confirm that others are experiencing this same problem before I decide what to do. It seems it would be best to get another one from Amazon instead of going through the hassle of repair.

I notified Amazon of the problem on Friday and got a brand new replacement on Monday. Talk about great service.
Unfortunately the replacement is a crapper also. My second Zen Micro immediately and completely locks up when plugging in the USB cable. Since I didn't return my original unit yet, I was able to try another cable but got the same results. I fully charged the batteries, tried all of the various recovery mode options, and still had the Creative drivers/software previously installed on my computer from before. I'm running WinXP SP2 with up-to-date patches, and no other software installed since. My PC's motherboard has built-in USB 2.0 support (with power mgmt turned off) and updated drivers and BIOS, but these things shouldn't be an issue anyway since it worked fine with the first Zen Micro. I'm not able to upgrade the firmware, let alone transfer music, because of the lockup problem. I build and fix PCs for friends and coworkers all the time so I'm confident in my trouble-shooting abilities.
The second Micro makes the first one seem perfect. I really wanted to like this MP3 player, but two defecti've products in a row is totally unacceptable to me. What a waste of my time. I should have been more suspicious about Creative products since my Muvo TX FM player was buggy as well (i.e. player would immediately shut down when powering on). I will check out the Rio Carbon or iRi'ver products instead.

Iphone 5s battery performance

I am very happy with my iphone 5s battery performance when it is on ios 7.0.5, standby time can reach 20 hours with usage time of 4 hours after every full charged. But, after updating to ios 7.0.6, the battery life became very poor, even now with 7.1 also same problem!!
Please, i want to have the previous battery performace.

One thing to check is Settings > Bluetooth. The update process turns it on. Turn it off if you don't use it.

Decreased Battery Performance when using SL. Apple states I am alone..

This thread is mainly aimed at people that are using a mid 2009 unibody MacBook Pro 13" or upwards that came pre-installed with Leopard. Since upgrading to Snow leopard have you noticed a significant decrease in how long the battery lasts while using the machine in the same fashion?
Am I alone? I first reported this issue to the Dutch customer service team back in October 2009 and since then have fought it all the way to make Apple admit that there is a problem with a minority of customers. To this day according to executive customer relations, I am the only person who has reported this issue to them. I find this hard to believe as there is a mass of information/threads/blogs etc on the internet with many people complaining about the same issue.
The following is an email I sent to the [email protected] email as a last resort.
Dear Steve,
I am writing to you as a last resort hoping that my complaint will be dealt with professionally as I have actually given up all hope with the Apple customer service. I do not expect that you will personally read this letter but I just trust that someone will care and pass this to someone that will treat my complaint seriously as I really am losing all faith with Apple.
I purchased a brand new Macbook Pro 13" mid 2009 model at the end of June 2009. Around 3 weeks after I purchased the machine I received a message from Apple stating that I was eligible for a copy of Snow Leopard as it was compatible with my machine and because I had just purchased a new Mac. I upgraded the Mac to Snow Leopard without any issues. It wasn't until a few weeks later that I noticed a massive reduction in battery performance. When I ran the machine on Leopard I would easily get the advertised 7 hour battery life while doing basic web browsing with all the battery settings set to the Mac default recommended settings. On Snow Leopard I would not get anything more than 4 hours completing the same tasks.
I contacted Apple about this and was provided with the following reference number XXXXXXXXX I was basically told that I should monitor what I was doing etc and try using the screen on the lowest setting to see if this would improve the performance, it did not. I am a busy man and work in graphic design so unfortunately I put up with the battery issue until my Hard Drive decided to die in April. I contacted Apple again about this and was again provided with a reference number XXXXXXXXXX this time I was asked to do various steps to help fix the machine which did not work. Eventually I had the machine booked in for repair. When the machine was booked in for repair I also stated that I would like the battery issue addressed once and for all as I still only get around 4 hours charge. I was told this would be looked into. After 2 weeks of having no machine (and losing out on work) I received my Mac back with a new Hard drive installed as the old one was corrupted. I asked the Apple employee if my battery had been addressed and it had not. I refused to except my machine back as the battery issue was not resolved. After another 2 weeks of not having my Mac (more loss of work on my account) I received it back this time a new battery and motherboard had been installed.
I returned to my office and reinstalled Snow Leopard, my Adobe Master Collection and charged to 100% I then tested the machine on battery. Again I received no more than 4 hours using BELOW recommended Mac battery settings. I contacted Apple again by telephone (another 0900 number call at my expense) and was messed around left right and centre. The employee on the telephone did not know what to do so transferred me to one of the Mac level 2 agents. I have never been spoken to so rudely and was even told that the only way I could expect 7 hours battery life from a MacBook Pro 2009 model is to use it with the lid closed. Ridiculous hey? I was also even told by one of the previous customer service agents that I could try using the machine with the battery disconnected. Even more ridiculous considering it is a unibody model.
At this point I started doing research on the issue and found that I was far from alone with the battery issue. I have found numerous people suffering from the same issue. Below are a few links containing the same issue.

At this point I decided to try something different, something that was not recommended or mentioned by any Apple employee, sales or technical. I decided to reformat the HD and install Leopard back on the on the machine. I then completed a battery test and low and behold my 7 hours of battery life were fully back. I think this can safely say that the issue is clearly with the OSX and not the hardware.
I then contacted Apple customer service by phone (more 0900 numbers at my expense) I spoke to a senior Applecare advisor called XXXXX XXXXXXXX and explained my issue in full. I told xxxxxxx that I wanted this matter looking into and that I wanted a machine that would give me what is advertised using Snow Leopard, as know where on the Apple site or in the Snow Leopard documentation does it state ' Expect to lose 3 hours '
I provided xxxxxxxx with a system info file and he sent it the Apple engineering team. A week went by and I received an email from him with the report from engineering. Engineering basically blamed it ALL on 3rd party applications, they even blamed it on the weather widget stating that it is constantly updating and will drain power. My remote access software was also blamed which was not even running in the background.
1: The weather widget updates when you select it not constantly.
2: The weather widget is by DEFAULT installed on a machine so thus would be classed as an Apple product in my opinion.
That evening I decided to reformat my HD and reinstall Snow Leopard. This time I installed ONLY Apple software updates and nothing else. I then tested the battery again (getting very boring now) using the same settings as previous tests. This time I managed to have 4 hrs and 15 mins. Just 15 minutes more than what I had previously had. I then contacted xxxxxxx again and provided him with another system information file from the clean install. I explained that I had tested this with just the airport on and basic web browsing on various sites (my exact words) Another week went by and I received a call from xxxxxxx with his report from engineering. He said that Engineering wanted to know if I had tested this with basic web browsing or sat on Youtube or other flash based video streaming sites for 4 hours as this could reduce the battery life.
As you could imagine I was furious. I repeated myself to xxxxxxx about my tests and was told that he would go back to engineering. I received another call from xxxxxxx stating that engineering are looking into it. I asked how long it would take for an answer on this and we agreed on a 2 week time frame. It is now over 2 weeks and I have sent 2 emails to xxxxxx and still have not received a reply.
This issue has been going on since October 2009 when I first reported it. We are now in July 2010 and I am still suffering with this, as you can imaging this is unacceptable and not what one would expect from a company like Apple. My complaints summarized are below, I believe the obvious speak for themselves.
1: There is no disclaimer on the Apple site stating that Snow Leopard will decrease the performance of a battery on a machine that did not come preinstalled with Snow Leopard. Neither is this information provided on the installation PDF instructions that come with the Snow Leopard disc.
2: If there were such a disclaimer on the Apple site then why would I have my battery and motherboard replaced by the Apple repair team when there was clearly nothing wrong with them in the first place. Why was I never told this by any agent on the phone or in the Mac store? The answer seems clearly that this information is not available to the public or to Apple staff which is a big waste or my time as well as theirs.
3: I have missed out on work because of having my Mac in for repair for a total of 4 weeks. As mentioned above there was clearly no need to have had the battery or motherboard replaced.
4: I have spent money calling the 0900 numbers on numerous occasions simply getting passed around from Apple employee to Apple employee and still have no answer to my problem.
5: I have wasted so much of my own time clean erasing my hard drive including zero out of sectors and reinstalling operating systems, not to mention other software and Apple updates. All of this comes to many hours of total wasted time at my expense when I could have been working.
Where we stand now is that I am on the verge of taking legal proceedings with the Dutch Consumentenbond as this machine is not suitable to run with the Snow Leopard OSX when Apple advertise that it is.
I expect either a full refund of my MacBook Pro 13" mid 2009 or an exchange for a Macbook Pro 13" that comes with Snow Leopard preinstalled with the disc in the box. I also expect to be compensated for my loss of time, money I have spent on the phone to Apple and the loss of work while the machine was in for unnecessary repair.
I am really at the end of my patience with this issue and feel that I have been much more than fair with my reports, honesty and patience.
I trust to hear from somebody soon regarding this issue so that we can finally put it to a close once and for all in a professional manor.
Regards
I received a phone call within 14 hours of sending the email from executive customer relations. They came back with new information from engineering but did not think it was acceptable as engineering were now blaming my battery decrease on the assumption that my apartment might be too hot this causing the CPU to run at a higher temperature making the battery decrease quicker. We both agreed that it was an unacceptable answer.
The day after I received another call from them stating that engineering had now finished tests and came to the conclusion that when testing on Leopard and Snow Leopard on the MacBook Pro 2009 there was no difference in battery run time whats so ever. I found this hard to believe so asked exactly how the test was conducted. Was it conducted in the same fashion that I had spent the last 9 months talking about. ' Using below default energy saving settings with only airport on while completing basic web browsing '???
They confirmed this was not the case, engineering had basically turned the machines on, turned the screen right down to 1 bar and left them on screen saver over night. As you can imaging I was speechless (for a few seconds)
Apple seem consistent on NOT admitting that there is an issue with battery performance for a minority of customers. As is stands now engineering in Europe have now passed the case over to engineering in the US for further ' in-depth ' tests.
I know there are people out there that are suffering the same issues as myself and I welcome you to please contact me with your experiences. As the more of us that complain about this make it harder for Apple to deny this and brush it under the carpet.

Please, nobody's going to waste their time reading all that! I don't know what you possibly could have said about this issue that took up so much space, but if you can't express it more concisely, it's probably not worth reading.
I have used SL on both a unibody MBP and an older MBP. On the older MBP, when I upgraded from Leopard to SL, I got a noticeable increase in battery life immediately. I have no such comparison on the unibody MBP, since it had SL installed to begin with, but I'll put it this way: I haven't come close to running out of power on it. I used it once for about 4 hours and still had more than a 1/3 charge. I could have easily used it for another couple hours, at least. And this was with a 17" MBP, which uses more power than your 13", and without much in the way of battery-saving going on. (Screen at full brightness, AirPort on and in use, Bluetooth on, etc.)
It's difficult to say that SL is the problem when it clearly isn't for everyone. What your problem is, I don't know, but maybe if you posted a more concise question you'd get some answers.
I think ..
This thread is mainly aimed at people that are using a mid 2009 unibody MacBook Pro 13" or upwards that came pre-installed with Leopard.....
at the beginning of the thread I made it pretty clear, if you are not affected by this then I'm happy for you, but then the thread is clearly not aimed at you. I can guarantee that I have tested this exactly the same way I did with Leopard and there is a significant decrease. I also know there are people out there that have gained battery life but there have also been many threads containing people who have lost battery life.

Check battery error with new and old batteries.

I came back from vacation last month, and the battery on my late 2006 Macbook would not charge. The Apple store said the magsafe connector was bad, and replaced it for $98. The next day I had the same problem, and when I took it back they said that now it was the logic board. None of the "geniuses" had any idea what was the failure was just swap parts until it works. I now have the "Check Battery" condition, and no idea what that means. I am sure that if I take it back to the Apple store they will say buy a new $100 battery, after all this one has three cycles on it! Dose anyone know what Check Battery means, and what conditions set this message, and how to clear it?

Thanks Carolyn. It appears that battery condition is set during a recalabrate only. It would be nice if Apple would produce a “white paper” on battery management for Li-ion batteries. There are no significant “trade secretes” in the management software that have not been reverse engineered long ago. Information as to what Recalibrating really does when it “Recalibrates”. What it means when Apple says the design life is 300 charge cycles. Information about how battery life is a statistical function, and may fail at 150 cycles, or may go 1000. What information the battery sends to the computer, and what the computer sends back. This would help eliminate the many posts on these forums, and people getting frustrated with the lack of information from Apple.
