Battery life degraded.

Hi guys, after 84 cycles i'm down to around 4600 if i'm lucky,
Now apple state that you shouldn't reach 80% within 300 cycles.
I did calculations and that would be ~4160 so apple said it was a perculiar issue and would not do a swap for the battery, but said i should take it to the local applecenter to be looked at.
By the sounds of it my chances are pretty low on getting the battery replaced right? i understand batteries are a disposable consumable that deteriorate but i bought this thing less than 6 months ago.

Yeah, that sounds like almost 80% and apple will have it replaced in that case
They said they should be replacing mine, i just have to take it in to the repair center because they want to see proof.
Apparently they haven't really heard of this issue much
While Battery Degradation is a normal thing, this is really only an 8% drop in capacity which ends up as about half an hour of normal load (~1000mah)
So i might just leave it and see how it goes, but apple agree that it shouldn't drop that much until atleast 100 cycles.

Battery Life Degrading after upgrading to Mountain Lion.

Hi Community Members,
Just after purchasing the Mid 2012 Macbook Air 13", the battery life was good 7+hours for usual use, including browsing, emails, vpn access etc. After upgrading to ML on 26th July 2012, the battery life depleted down to barely 3.5 hrs now, very disappointed with this experience barely after a few weeks of this new portable. Tried some workarounds for like the SMC reset, uninstalling Flash etc but no success. Don't have power nap enabled which a lot of people feel is the reason for the battery draining out. More concerning is that the FCC ( Full Charge Capacity) has dropped to 96% ( 6431 mAh) from its original 6700 mAh with the Power Cycle count as 24. Spoke to Apple Care today and has been advised to do a Battery Calibration and then get the battery checked up at an Authorised Service Centre. Apple claims it has nothing to do with the Mountain Lion upgrade. Will come back with more updates tomorrow.
Any workarounds or success stories with others ?? Very unhappy and disappointed with my new Mac !!!
Cheers

Battery Life Degraded After Restoring from Jailbreak

I recently did a jailbreak on my phone and decided I didn't like it. I restored the phone to Apple factory settings and everything is fine except the battery. It will not hold a charge more than a few hours -- and that's on STANDBY, not actually using the phone or making calls!
Is there anything else I need to do to erase all traces of the jailbreak? Or is there anything I can do to improve my battery life?
I've already done the following:
1) lowered the screen brightness
2) close programs when not in use
3) changed auto-lock time to 1 minute (the shortest possible)

Very few applications run in the background - the number of applications that run in the background are very few and far between. An app being in the recently used apps bar or dock means just that - it was recently used. It does not mean the apps are running in the background.

MBPr 2012 Battery Life Degraded Rapidly

MBP retina July 2012 edition
8GB
2.3Ghz i7
OSX 10.10.1
Purchased refurbished in May 2014
Here is my my issue. My battery life is currently at 94% health according to iStat Pro. A few months ago I was getting 8 hrs of battery life running safari and microsoft one note at 30-40% brightness and wifi on (no bluetooth or keyboard lighting). Now I am getting 4.5 hrs with these same settings. This drop in battery life has seriously affected my work day and really been annoying. I am wondering if there is some setting that got flipped that is killing the battery or if this is a battery malfunction that needs to be addressed at the apple store.
Let me know if you have any questions and thank you for the help!

Have you tried a SMC reset?
http://support.apple.com/en-us/HT201295
Based on the purchase date, your MBP is in the warranty period. Perhaps an evaluation at an Apple store genius bar is in order.
Ciao.

Does leaving macbook air on all the time (while plugged in) to download torrents degrade battery life?

Does leaving macbook air on all the time (while plugged in) to download torrents degrade battery life?

You have a lot of things going on here...you are keeping the Air plugged in all the time, you should run on the battery periodically to give it some exercise, you are keeping it on all the time which may be keeping it under constant or near constant load, and you are doing all of that to download pirated content, for which you will get no help on here.

3gs 5.0.1 update degrades my battery life in about 2-3 hours. HELP send me a fix!

I downloaded the 5.0.1 upgrade a few days ago and just in 2-3 hours I loose almost all my battery life even if I shut down all apps. Whats going on and how do I fix this?

Do you have wifi syncing turned on? Is your itunes always open?
There is a glitch with the iPad where, as long and anytime iTunes is open, it'll sync...like once an hour or some such rate.
Originally the wifi syncing was only supposed to take place if the device is plugged into power, but that's not the case. If I have my iTunes open my iPad will try to sync almost continuously.
So check your wifi sync and iTunes settings (my iTunes used to be set to open automatically when the device is connected, I had to change it to only open when I do it manually because in the course of an evening's surfing my iPad opened my iTunes and started to sync three different times until I turned it off)
If you have iCloud syncing enabled that may also be contributing to your battery issues. I don't sync over iCloud, I tried it but after it ate all my contacts, I stopped using it. However, if the same glitch is present, the device trying to continually sync even when not plugged into power, that could also be part of your drain.

MBP early 2011 battery life

I have the early 2011 release of the 17" MBP (8gig ram, 2.2ghz quad i7, 500 gig harddrive) and it seems like the battery life has just been cut inhalf. It lasts me about 3 and a half hours from just general use. Is my battery faulty? Really appriciate any feed back

That battery looks pretty good, capacity is really strong for so many charge cycles, but the voltage looks low, would expect it to be in the 11.5 to 12.5 volt range and you are showing 11.27 volts. A little low but not critical.
How have you been handling that battery with respect to discharge/charge? While Apple has a lot of material talking about periodic deep discharge to shutdown and charge as a means of calibrating the battery, in reality that does not calibrate the battery itself. That only serves to calibrate the charge reporting circuitry built in to Lithium-technology batteries. In fact, the Battery University, an independent group testing batteries, has shown that repeated deep discharge behavior significantly shortens Lithium battery lifetimes. The optimum balance of use (discharge) and line-connection seems to be around 50% discharge before charge. Deeper reduces cycle life very fast, lower discharge makes for a very high cycle life but why buy a portable?
Anyway, just some thoughts. Use of high intensity applications, including other operating systems, looks like it is degrading the charge time but the battery itself looks healthy.
Just keep using it, perhaps try not discharging below 50% for a while and see how it behaves for your.

Centro Battery Life

After 3 Palm PDAs, I was excited to get a Palm Centro. In the first 30 days it became obvious battery life was horrible. Best Buy swapped first the battery, then the entire device. After that they referred me to AT&T who swapped the phone and at least 4 batteries until the 1 year warranty ran out. AT&T was very helpful during the first year warranty period, but I've still got 8 months on my contract, and my battery does good to last 6-8 hours. Charging it for use first thing the next day isn't possible. I make very few phone calls, literally 2-3 a week, so it's totally standby time I'm fighting with. I don't use any data connections (no e-mail, no gps, no web). I don't use texting or any third party software. I turn bluetooth off except for once a month to sync with my Vista 64 computer. AT&T has checked the settings and found nothing wrong. I'm reluctant to spend $50 for a battery that will only last a month or two, I might as well buy an I-Phone for that price (except I don't want the required data connection). I've even tried turning the radio transmitter off, charging it at 11 PM, and the next morning, it's still dead! Just totally unacceptable, and before now, unlike Palm quality. An e-mail from Palm today advertising the new palm pre plus just set me off. Why would I upgrade with my experience with Palm's quality and response to a major issue. I thought I was alone, I wish I'd read all the reviews before I bought my Centro, I would have continued using my old phone, and will probably have to go back to it if I every want to make an actual phone call.
I would expect Palm to replace the battery for at least the first 2 years when it's obviously not a user issue!

I'm in a great coverage area and battery life isn't any better if my radio transmitter is turned on or off. Also brand new batteries seem to work fine for several weeks to a month or so, then start degrading. I followed the manuals and AT&Ts recommendation to the letter on charging & recharging. My wife's Centro is in the same location and has almost identical usage and works fine. I've had lots of suggestions and "it might be's" and tried and eliminated them all, and still have a battery that won't hold a charge.

What is the recommended way of preserving battery life?

I'm a bit confused. How do I preserve the battery life for an old (2008-ish) model of a white MacBook?
Some part of the internet says that:
Letting the MacBook plugged in to a power outlet even if the battery is full will result in the battery degrading its life (aka do not overcharge the battery because it's bad).
Another part of the internet says:
Removing the MacBook's power adapter when the battery is full will result in the battery degrading its life because it will get used more. (aka the battery will be overused because of not running on power adapter which is bad)
So can anyone clear this up for me? I's really confusing and I need a definite answer, thanks!

I bought my 15" macbook pro i7 just a year ago and my battery life runs out extremely quick..at fully charged it says I only have 2:27 of usage time. I didn't pay for that-what can I do about it? I do have Apple care. Thanks.

I bought my 15" macbook pro just a year ago and my battery life runs out extremely quickly. This started maybe a month or two ago. Its hard to tell. I only noticed the rapid change recently. Fully charged it says I have 2:27 (2 hours and 27 minutes) of usage time...with about 50% screen and keyboard brightness.
I've checked inside system preferences and its cycle count is 261 and full charging cap is 6316.
I have apple care...is this something i can/need to take up with apple. You'd think if you pay the price for these machines you should get mroe use out of them.
ONLY A YEAR I'VE HAD THIS!
My PC lasted 4 years before the battery showed signs this dramatic of wear.
Any help is appreciated, im new mac owner. thanks.

do you have a mbp with dual video cards? running the system with the higher end card increases the heat and also drains batt power.
i have the 1st gen unibody (2008) with an original removable battery of 311 cycles and 4453 charge. under normal use ill be happy to get 1.5hrs. the mac battery counter thing says i have 3.3hrs though (whatever). compared to me, i think you use your battery more than i do, perhaps its the reason why it degraded so fast in a year?

HOW TO MAXIMIZE YOUR LAPTOP'S BATTERY LIFE

Hi all,
I had this bad experience of this wide problem in laptops, battery failure. It happens almost just after your warranty expires many will agree, funny & true..battery stops charging, shows less than 100% or 0% charge no matter how you try to charge it..etc. Also many complain that the battery shows only remaining charge time, and not the time remaining (read 9th tip below).
Though Mark, Andy, vkyr, nonny, jhem, bill, myles and other admin guys are here to help on this forum, I thought of writing this based on my own experience of these batteries till date..I had compiled a few tips and information for dummies about the use of battery here which might help you to extend battery life:
NOTE to moderatos--please check / modify / add / edit in the following if you find any wrong information.
NOTE to all -- These tips in no way will harm your system, except the 9th tip and also if you remove battery without shutting down laptop
All are welcome to add any new tips or corrections.
1. Never discharge battery to 0%. Always, ALWAYS let battery discharge to a lower limit of up to about 5 to 10%.
2. To run it or not on AC supply without battery If you use laptop most of the time at home or a place where there is a continuous (= uninterrupted) power supply, then simply remove battery from laptop and run laptop on AC power. If you are doubtful about current surge in AC supply, use a surge protector or a UPS (uninterrupted power supply) unit, which doesn't cost much. But be prepared, sometimes you may lose the data which is not saved, due to any accidental interruption. As [Bill] pointed out there might be a performance degradation due to power failure.This is not recommended if you are unsure of power supply.
3. If you use AC power most of the time, then store battery with 30 to 50% (about 40% optimum) charged condition in a dry, away from any magnetism. At least once in a week or two weeks, run the laptop on only battery supply, let discharge it to about 10%, connect to AC supply, charge battery to 100%. Shut down, disconnect supply, remove battery from laptop and then use AC power supply as usual again.
4. If you are running out of remaining battery time, then instead of shutting down PC, hibernate it ( you need to enable hibernation before through power settings in control panel). Shutting down takes more time than hibernation and without saving anything, you can resume your work after hibernation. After hibernating, even if you remove battery, it won't lose any data and will resume once you connect laptop to a power supply.
5. Use power schemes (power management profiles), modify options available in power options under control panel in windows according to your usage & habits. Instead of using a blank screensaver or a screensaver which looks cool, turn OFF monitor, use lenovo power management options or windows power schemes to do this.[Tom&Wjli2]
6. When running on batteries, to save power - reduce brightness of screen (using keys Fn + F10 to reduce, Fn + F11 to increase), mute volume & turn off any unnecessary devices that you are not going to use like (thanks to [Nicolas])bluetooth / modem / plug&play monitor / network adapters(wireless/ethernet/lan/1394) / PCMCIA adapter. Use 'control panel->system->hardware->device manager' to turn these devices on and off.
Changing color schemes to dark or black colors doesn't save power in case of LCDs. (http://savingenergy.wordpress.com/2006/11/21/saving-energy-one-monitor-at-a-time/)
7. Whatever you try, a battery has a specific life time (no. of charging/discharging cycles), and it discharges slightly/continuously over a long period even when not in use. So if your battery is giving problems after about 3 years of service, then it is time for its replacement. Don't assume that if you don't use battery more often, it will last longer, it may usually, but battery failures are unpredictable.
8. If your battery has started to show problems, it will most likely fail sooner or later. Consult experts if battery is under warranty, else buy a new one.
9. Either use lenovo's default program or you might try a program like Notebook Hardware Control (http://www.pbus-167.com/ ) to monitor your power & hardware / temperature. This program shows remaining battery time once you modify advanced options for battery. Also it shows various temperatures for CPU/HDD and warns you if temperature reaches preset limit.
Caution: though this program allows, don't try to modify voltage settings under advanced options, it can harm to your system.
Added:
10. Never run a hot laptop or a hot battery. It damages the battery/laptop, so be sure to keep temperatures within normal range.(below 140 F or 60 deg C).
11. There are few more good/advanced points added by Tom on Page 2.

Dear iamdh,
Thanks for your answer and your update of the main post. I also read the various interesting articles you mentioned.
Now, I would like to submit to you these interesting questions :
Question 1 : Please do the following test : Open Paint, enlarge to full screen, set image size at least the size of your LCD (e.g. 1500 x 1200 dots) and use bucket tool to fill the whole image in pure black. Now, go to control panel, display, screensaver tab, and select Blank screensaver and test it with the View button. DO YOU SEE A DIFFERENCE between the black screen in Paint and the blank screen of screensaver ?
I don't see any difference (I use a vaio A517S laptop with high brightness LCD), so the conclusion might be that the blank screensaver uses up the same energy than a black color screen. A 2nd experiment leads to the same conclusion more conclusively : View again the "blank" screen (in screensaver tab, View button) and play with the Fn Keys to change brighness. You will notice that that it is impacted by brightness level which means the blankscreen is NOT a real "blank". WHY IS IT IMPORTANT ? Because, if choosing the Blank screensaver uses up the same energy as a black screen, AND because the black screen doesn't make any difference with a white screen on a LCD (remember the paper you found), then, why choose the Blank screensaver !!? Or, is it the fact that colors don't make any difference with LCD which is wrong !?? At that stage, I only ask. It is logic, it is one or the other, isn't it ? Any comments welcome.
Question 2 : You remember that energy transforms into various forms : light, temperature, strength, movement, etc... Now, let's come back to LCD monitor : IF a black full screen and a white full screen uses up the same energy (youy remember the paper http://savingenergy.wordpress.com/2006/11/21/saving-energy-one-monitor-at-a-time/), then, there is a interesting point : Because the white screen gives more light than the black (you can check that in the middle of the night using your laptop as a spotlight torche !), it means that the black uses up its energy into an other form. ...What could it be, other than temperature ? LET'S PUT IT AGAIN DIFFERENTLY : The black screen and the white screen use up the same energy, but why it is used for brighter light with the white, it is used for higher temperature with the dark. WHY IS IT IMPORTANT ? Because higher laptop temperatures damage batteries quicker, then it means that we should avoid dark colors and prefer light colors in our windows settings. .. any comment welcome
Really, the central point of discussion is the fact that electricity LCD consumption is not impacted by colors, even white or black. Has it been really double checked by many ? A story to follow..

I have the 13" Late 2011 Macbook Pro, What are the best Battery Life saver/increaser Techniques?

Specs-
2.4 Ghz Intel Core i5
4GB 1333 MHz DDR3
intel HD 3000 384 MB
How can I prevent My battery from degrading or atleast make the degrading slower
Can Ya tell me the steps or things to do?
I use my Mac a lot, like 6-15 hours everyday.
Someone told me I should keep it plugged with decharging it fully once a week.
is it true?
Can anything else be done?

You can use it on battery almost full time. It will slowly discharge to about 95% on AC, but then recharge after dropping below 95%. This is to save the use of the recharge circuits.
You should use it on battery only down to 40% at least once per month. Running it to dead will shorten battery life, not help.
The battery is rated to 1000 cycles. Two recharges from 50% to full is 1 cycle, 3 recharges from 33% to 100% is 1 cycle, etc ...
If you plan to store it unused for 3 months, discharge the batery to 50%, then remove from the MBP to preent the battery going down to 0.

Battery life comparison between 1.0.2 and 1.1.1

I had to have Apple Care send me a replacement phone because of battery issues.
I received the replacement phone, and interestingly, it still had the 1.0.2 firmware on it.
If enough people are interested here, I can run a fairly scientific test to see if there's any difference between 1.0.2 and 1.1.1 in regard to battery life.
I could leave the 1.0.2 software on it, charge it fully, then at 10 pm, put it in a specific place in my house, then see what the battery is at @ 7 am. Then, the next day, I can update to 1.1.1 and do exactly the same thing with the same settings.
But if the battery issue has been put to rest, or if people think this isn't a scientific test at all I don't want to waste my time.

Your post is helpful in that it points out that it'd be a very difficult thing to do a scientific test that proves anything.
In your usage, you left out surfing the web, which I do quite avidly. I also check my email much more frequently (every 30 minutes, as I've said). I can't test for surfing the web while I'm sleeping.
Your saying that updates have nothing to do with the battery is not at all a scientific case study and has very little resonance, but it's great that in your personal experience you haven't seen a degradation in battery life. A bug can rear it's ugly head in many different places, and your usage of the phone may not hit it if in fact there is one.
Just as an endless loop in a program can cause a computer's CPU to spike if an uncommon set of events leads to it, something could be happening with the phone for some users who are using their phone in a specific way.
So, having said that, I think I might've answered my own question in that there might not be any scientific way to do a test.

Is my battery life gone? R.I.P

I have used my ibook G4 for 1year and 3 month already, but now the battery suddenly showing some strange loss of its battery life, it takes only around 50 minutes for full charge, and after that only around 45 minute i can use before it drains out,
usually when the battery drains out, my ibook will go to sleep mode and it will maintain the sleep mode as long as i want it to be, but now what suprise me, when the battery drains out, it will suddenly turn off my computer instead going to sleep mode, it have happen twice now, so thats what makes me very worried, im so frustrated because i take care the battery so well but it suddenly become like this, not in a degrading fashion, its all in a sudden...since 2 days ago...
first question of all, is my battery life altered? or my battery already dying? what should i do? change to new battery? the new battery is so expensive...
2nd question, will my computer be damaged if it suddenly turn off like that without shutting it down properly?
hope somebody can help me on this

Welcome to Discussions!
Yes, if your iBook is not going in to "sleep mode", and abruptly turning off, it can cause damage over time. You said that is "fully charged" after 50min. Try leaving it plugged in for a full 24 hours, and see if that extends battery life at all.
Question? Are you running any processer intensive applications when its on the battery? Anything such as an audio/video application, anything with mathmatiacal equations, playing games, using the CD ROM drive, ect... All of those factors can shorten battery life. When the iBook runs out of power, it should automatically go to sleep, and remain in sleep for a day or two before finally shutting off.
Try resetting the PMU (Power Management Unit) ((taken from the Apple Support website))
1. If the computer is on, turn it off.
Reset the power manager by simultaneously pressing and then releasing Shift-Control-Option-Power on the keyboard. Do not press the fn (Function) key while using this combination of keystrokes.
Wait 5 seconds.
Press the Power button to restart the iBook computer.
Reset the PRAM:
1. Shut down the computer.
2. Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4.
3. Turn on the computer.
4. Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
5. Hold the keys down until the computer restarts and you hear the startup sound for the second time.
6. Release the keys.
Reset the NVRAM:
1. Turn on your iBook
2. Before the grey screen, press command-option-O (letter)-F
((O is for "open", and F is for "firmware"))
3. You will be at a grey screen displaying some information.
4. At the Prompt, type "reset-nvram" press return.
5. Type "reset-all" press return
6. Type "mac-boot" press return
I hope this helps!
Best,

How to prolong my battery life

Hi guys. I had a 12 inch powerbook a few years ago and I had it plugged in for ages. Its battery was horrible and would last a matter of minutes. On my new PB (15") I decided I would use the battery sometimes. I would have it plugged in, and when fully charged I would unplug it. Then when I got to about 15% I would plug it back in. I have a widget that shows me the capacity status of the battery. After a year it was 80%. A month later, 70%. After a 2-week leave and another month of use it was down to 40% and 3 weeks later 30% where it has stayed for a few weeks now. I was about to buy a new battery when mine got recalled. Isn't that convenient? Anyways, do you guys have suggestions on how to prevent this fast paced degradation of batteries or will I have to dish out 120 bucks every year if I want a half way decent battery. Also should I calibrate my new battery?
thanks,
axel

Note Apple measures battery life by the number of
charge/discharge cycles, and not calendar time. They
say a properly maintained battery should retain 80%
capacity after 300 charge/discharge cycles.
Slight adjustment to that...measuring in cycles is not an Apple quirk. It is an industry accepted way to measure lithium-ion battery usage.
See: How to Prolong Lithium-Based Batteries
In that tech note you'll find that for laptop use, battery life is usually affected more by heat exposure than usage habits.

Battery life degraded.
