Sudden drop in battery performance / condition

I have a late 2010 MacBook Air. Battery suddenly says "Service Battery". Was away for 11 days and when opened air to use noticed this?

Do what it says. If it's the MBA's original battery it's probably due for replacement.

Sudden drop in battery performance?

I've had my iPhone 3gs since release, been more than happy with the battery performance untill the last two days. The battery is dropping 2% at a time suddenly. Very quickly. I have restored the phone. I am getting concerned. Any ideas?

Lots of threads about this. Seems to be an issue with the 3.0.1 update or the way it affects certain apps. There are a couple step-by-step tutorials about resetting the battery sensor, restoring as a new phone, etc. Try one or all of those and see if it helps.

Sudden change in battery performance

Hello. I am having trouble with my battery. I charge my phone every night, and ever since the last software update (2.1) have had great performance. This performance has changed this week, as my battery is already drained today at 230p. (Last week I could go all day and not get the low battery warning.) I have not made any calls today and have only used the ipod for ~30 minutes and email for ~5 minutes. 3G is turned off. Wifi is turned off. Bluetooth is turned off. Has anyone else seen a similar sudden change in performance? Is there anything I can do to fix this problem? I could understand losing charge if I was using the phone, but since it's just sitting idle in my pocket I cannot figure out why I would have such a low battery.
Thanks

Something just got stuck in memory processing.
Try a reboot (described below).
Think of it this way, the iPhone is more of a computer than a phone. It suffers from being a new OS and nobody can deny there are not bugs and memory leaks. The longer left running, the more things start to fail or slow down (I have had the iPhone since day one of original phone and I am just speaking from my experience). Thus I equate it to like when Windows95 came out...not sure of your age or if you remember those days...but back then it was a running joke of how many days you can keep Windows 95 running before you had to reboot. I am sorry to say but the iPhone is the same way right now (but getting better with a few hiccups back during the 2.0 release). So for me, I reboot daily when I leave in the morning and take it off the charger. By doing so I rarely see any lag or problems.
A reset/reboot is:
Go to Home Screen
Press and Hold Home Button
Keep holding and press and hold Lock Button
Keep holding Both
You will see Slide to Turn Off (Don't let go to slide, just keep holding)
The phone will turn off (in time, but screen will look like it has some white lines)
Keep Holding
When you see the Apple Logo, you can let go.
Turning off via the Slide to Turn off while good and fine to turn off, is more like the Sleep Mode on a computer. Thus any locked up issues in memory remain when you turn back on. A reboot as described is like doing a real Turn off and Turn On on a computer.
You may also wish to read this tread about reboots and odd application behavior.

Sudden Drop in WiFi Performance - iBook G4

My wife's iBook G4 14" (1.1 GHz CPU) with Airport Extreme card has had great wireless performance since we've had it. About a month ago, it began having terrible reception. It used to connect fine from upstairs. Now it can only connect consistently within about 20 feet of the wireless router (a Linksys WRT54G v2.1). At the Apple store, its wireless performance is spotty as well.
The Genius at the Genius Bar says it needs the $300 "Fix everything" treatment. I'm, of course, reluctant to spend $300 to fix a now-obsolete machine and just as reluctant to drop $1k+ for a new replacement.
My question: has anyone else seen this problem? What fixed it?

Hi and welcome to Apple Discussions.
There's a few things that it could be but for starters have a look at : Antenna and check underneath the keyboard to make sure that the AX card and antenna are seated properly. Don't be surprised if you don't see a card there though as later models had an integrated card on the logic board. Nothing can be done re connections if you have one of those.
Second thing to try is to download and run MacStumbler to see if a neighbour is using a wireless router on the same channel as yours. If so, log into your router, (the documentation that came with it will have the procedure and password) and change the channel. You don't need to do anything with the iBook, it will adjust accordingly after a brief loss of connection.
Try the above and post back.
Good luck,
Adrian

N8 Sudden Decrease In Battery Life

I have had my N8 for years and have loved it every minute. Through ^3, Anna, and Belle i've always had 2 days of battery life with average use (power saving off). Last week however, my N8 suddenly had battery issues. There were no app, firmware, or setting changes preceding. So it's not anything obvious draining it.
When I charged the phone overnight (wall charger), I'd wake up in the morning and see Nokia Battery Monitor showing that the phone stopped charging prior to 100%. For example it would state: "Charged xHr yMins ago to 95%" or "98%". Occasionally it would also show up at 100%.
With this also came a drastic sudden drop in battery life. I would see approximatley 14-15h of life, and now I'm down to about 9-10. When looking at NBM stats, it would say "Background" used >100% of battery life at times. Under background would be things like Messaging, Music Player, and Notes, which is completely wrong. See below:
Here's what ive tried so far:
1) Use AppStop to kill all background apps, no effect.
2) 7370 hard reset to clear everything and go to factory settings. Wiped phone, mass, and card. No effect. Used AppStop to get to bare minimums. No effect.
3) Reinstalled Belle via Suite. No effect.
4) Let battery drain until it shut off, then used wall charger while phone stayed off overnight. Nope
5) Let battery drain down til shut off, then used USB charging. Nothing. Repeated this hoping it would "recalibrate" battery levels. Nothing.
Nokia Energy Profiler Stats:
Ran this for about 20 mins to get some stats:
1) Idle draw with screen on is about 0.20-0.30W, 15% CPU consumption. Occasional spike up to 30%.
2) Idle with screen off is barely 0.02W, 3-4% CPU consuption. Occasional spike.
3) Based on the power consumption, it still estimates that I should get 40+ hours of battery life on a full charge.
Battery lasting less than a day? I feel like an iPhone user. I get that I could always turn 3G off or power saving on and stretch it a bit more, but that's not a fix, it's just a Band-Aid over a bigger issue. Anybody have ideas? Should I buy a new battery and replace it?

Updates: So I bought a brand new genuine BL-4D hoping it would fix the problem. Nope, didn't happen...though the battery seems to now charge to 100%. EIther way this leads me to believe it's not a battery problem. Unless there's an issue with the charging circuit, this I"m back to a consumption problem.
So I tried another belle refresh and a "Factory Settings" restore from the menu, didn't help. Not sure what to do now, as Battery Monitor doesn't really point me to anything that's killing the battery. So I decided to do more research with Energy Profiler and ran it for approx. 50 mins to see what the consumption deal is.
I exported the data as a .csv and cleaned up the data. I've attached the power and current graphs. In both graphs you see that there's very low consumption immediately after starting the measurement and locking the phone. Afterwards, there are two distinct idle consumption values, approx 42mA (.16W) and 130mA (.49W).
An average 42mA power draw would give me approx 28.5h battery life (1200mAh/42mA=28.57h). However an average power draw of 130mA would result in a 9.2h battery life. The actual average of all my Current data points is approx 99.9mA, giving me 12h of battery life, which is about what I'm seeing at the moment.
I know my idle consumption is lower with 3G off and even lower with power saving on, but I haven't gotten the chance to record these measurements yet.
I'm still not sure what's causing a high idle power consumption, any ideas?

Sudden drop in iBook g4 battery life?

My wife's iBook G4 maintained a truly stellar battery performance from purchase to sometime last week, regularly delivering between 3 and 4 hours per charge. Sometime last week, that changed very suddenly and dramatically to just over 30 minutes.
While gradually declining battery life is the norm, such a precipitous decline makes me very strongly suspect that the battery is still holding a charge in line with the battery's track record and that the low-charge message is some sort of bug.
Is there any record of such an issue, how do I verify or dismiss my suspicions, and what might account for a sudden loss of over three hours of charge time?

Hi Mike,
Difficult to say without knowing how old your wife's iBook is and how many charge cycles the battery has done. As I understand it, the loss of battery capacity due to age/charging cycles is non linear and that capacity can drop dramatically and suddenly after 2-3 yrs/300-500 charge cycles.
(Very vague, I know. Such is the nature of the beast.)
You have omitted to mention which OS is relevant but if your wife's iBook is running 10.4 the battery info can be obtained via the Apple menu>About this Mac>More info, then scroll down to Power.
If the OS is 10.3.x then open Terminal in Applications>Utilities and enter:
ioreg -w0 -l|grep Capacity
and press return. (Works in 10.4 too…)
Either way, copy and paste the info into a reply here and someone will be able to give a more informed opinion.

MacBook Pro late 2011 Battery Performance drop dramatically

MacBook Pro late 2011 Battery Performance drop dramatically
9 months 94 cycles and its health is now at 89%

Does the system still run off the battery only? Does it run for a few hours off the battery only? Then No it is not defective and no Apple will do nothing for you and No Applecare does not cover Consumable items which the battery is one of those.
The only time Apple MAY, and that is BIG MAY, replace the battery is within the first year and only if Apple Deems the battery to be defective. Fat chance of that as long as the system runs off the battery for any length of time.

T430s battery capacity sudden drop

Hi, I have a look at my battery report today and found something really awkward. I bought the computer seven months ago, and the battery start with Design capacity 44,000wWh, while the full charge capacity is quite closer to the design capacity. However in the battery report it shows that two weeks ago the design capacity suddenly drop from 44000 to 40734mWh in one week, and then afterwards it drop to 39000mWh. And the actual full charge capacity seems to linger around 37000mWh. Is there something wrong or is my battery just wear out naturally? Best,Eddy

Full charge capacity will decline with battery age and number of recharge cycles. Lenovo warrants their batteries for 1 year. IIRC if the full charge capacity drops below 80% of design capacity in the first year you are eligible for a new battery. 80% of 44,000mWh is ~35,000mWh. I would keep an eye on full charge capacity over the remaining 5 months of your warranty.

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.

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.

Random drop in battery charge while using plugged-in computer

Hey everyone,
I bought my Macbook Pro a couple weeks ago and have generally used it while it is plugged in. Recently I've noticed that while I am using it, the battery charge will suddenly drop from 100% to around 50-60% and the MagSafe adapter will change from green to amber and begin charging the battery until it reaches 100% again. I calibrated the battery the day that I got it and I have never had a problem like this until now. CoconutBattery even says that my battery capacity is more than 100% of what it should be. Please let me know if this is something I should worry about!

I just noticed it happening again.
very strange.
AC Adapter connected and green
icon in menu bar shows AC is connected, not charging.
system profiler shows -1900 to -2500 mA
system profiler shows Fully Charged: No
system profiler shows Charging: No
I am starting to suspect it's related to the ipad being connected, as that takes a good chunk of power to charge.
I wonder if what's happening is that that with everything powered up on the macbook (External display, external Firewire hard drive, USB keyboard, Screen lit up, iPad connected) if it's somehow exceeding the capacity of the magsafe 85W power supply.
to test this out,
I've disconnected the ipad, firewire hard drive, and second display,
done a SMB and PRAM reset
and am charging the battery now.
after that I'll do a calibrate and try to avoid connecting things for the next few days to see what happens.

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!

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.

When I am on Firefox, my Netzero email page suddenly dropped to very small print. AOL OK. How do I increase size of the print so I can read the email?

I was using Firefox to read my Netzero email. The print suddenly dropped down to very small and I have difficulty reading the email. Netzero said to oper Mozilla Firefox, click "tools", click "options", and click "content" to change the font to a bigger size. But when I clicked the brown "Firefox" button on the Firefox page, I do not see the buttons Netzero told me to click. Can you tell me what they are referring to or just tell me how to increase the size of the font when I am reading email on Netzero. AOL email font size was not affected when I clicked AOL to read the email there.
