Battery cycles before replacement

Hello,
I own a MacBook Pro 13" mid-2012 and an AppleCare for it.
I'm wondering at how many battery cycles i can go to a Genius Bar to replace it. Is it 1000 cycles (the life expectency of my battery), more, or must i look at his health ?
Thanks, and sorry if i made mistakes, i'm French

Section : Battery warranty information
Your one-year warranty includes replacement coverage for a defective battery. You can extend your replacement coverage for a defective battery to three years from the date of your notebook purchase with the AppleCare Protection Plan. However, the AppleCare Protection Plan for notebook computers does not cover batteries that have stopped working or are exhibiting diminished capacity due to normal use except when it is the result of a manufacturing defect.

MacBook Pro -- how many battery cycles before time to replace battery?

Got a 5 year old MacBook Pro. There are around 95 battery cycles on the battery. It's the original battery. How many cycles should I expect before it's time to replace?
I ask because Checkmate is suggesting it's time.

Optimizing iPhone battery life: Between charges and before replacement

FYI. An excellent iPhone battery care article by iPhoneAtlas.com:
Optimizing iPhone battery life: Between charges and before replacement
http://www.iphoneatlas.com/2007/07/09/optimizing-iphone-battery-life-between-cha rges-and-before-replacement/

OK, I agree that is a completely false statement. The rest of the article is pretty good.
If you assume a linear decrease in battery charge for each full cycle (which it really isn't, but much easier to model in a spreadsheet). Then 80% of original charge after 400 full cycles is approximately 0.8% loss in battery charge per full charge cycle (again this is a simplification, stay with me). This means that after 400 cycles, you are at approximately 80% of your original total charge level. As stated by Apple.
So, extrapolating that out to EOL (end of life) which Apple assumes to be 50% battery charge, it would take approximately 1,000 full charge cycles for your battery to be EOL (according to Apple). It would actually be slightly less than that since it won't be a linear function.
For me, that's 2 to 4 years of use depending on whether or not I continue using the iPhone as much as I have this first full week.

MBP running out of battery power before sleeping - Help!

Hi
My MacBook Pro has been running out of battery power before the memory-saving sleep mode kicks in, so it dies with a little click of the HD. It's not a hibernation state as when I reattach the power supply it boots up a new session.
I've noticed this since upgrading to Snow Leopard last year, but put it down to an old battery that had 45% charge and wasn't powering the MBP properly. I now have a replacement A1175 5600mAh battery which is giving me 2-3hrs usage (which I'm pleased at), but now it still dies before sleeping!
I have tried to cycle the new battery, but can't. I have reset the SMC several times, with no effect.
I used to cycle the battery every week or two, running it down until it would no longer wake from sleep, recharge overnight etc, but now I can't do this because it will die before sleeping!
I've read quite a few articles over the net about this issue, but there seems like no cure. It's really annoying me now as I frequently work on the move and a dying MBP could potentially be disastrous.
Can anyone shed some light on this issue? Is there something I haven't tried yet? I think it's a late '06 MBP.

If you are not getting a warning, then there is something amiss with your battery. If a SMC reset and calibration does not fix the problem, then you may need to make an appointment at the genius bar and arrange to have your battery tested.
My old battery started doing the same thing--shutting down without warning. I replaced it, and the replacement battery started doing the exact same thing. I then returned the replacement, and the next replacement battery behaves in a normal fashion.
My first battery was worn out. My second battery was defective. My third battery is good.
Your battery should still be under warranty. Go back to where you got it and show them what it is doing and see if you can get a replacement.
Good luck!

Macbook pro battery cycles

I have 385 battery cycles on my 2009 MacBook Pro 17—no problems yet. How much longer can I expect the battery to hold up, what is the process to get a new battery, and how much will it cost?

Here is a copy & paste straight out of the operating system:
The battery condition tells you whether your battery is functioning normally and approximately how much charge it can hold.
Here are the possible conditions:
Normal: The battery is functioning normally.
Replace Soon: The battery is functioning normally but holds less charge than it did when it was new.
Replace Now: The battery is functioning normally but holds significantly less charge than it did when it was new. You can continue to use the battery until you replace it without harming your computer.
Service Battery: The battery isn’t functioning normally, and you may or may not notice a change in its behavior or the amount of charge it holds. Have your computer checked by an Apple Authorized Service Provider (AASP). You can continue to use your battery before it’s checked without harming your computer.

Can I keep plugging in my iphone to the power supply despite fully charged to reduce the battery cycle?

Since an iphone battery lasts for 300-500 cycles before losing its juice, can I just continuously connect my iphone to the power supply to avoid using the battery, like how I use my macbook.

Yes, you can but best read this

How can I see the quantity of battery cycles on Satellite U200-181?

I have Satellite U200-181, and I use it hard, every. I want to be ready replace my battery, when it will have 400 cycles.
How can I see the quantity of battery cycles on my laptop?

You must not see this. You will see that capacity of the battery drops down and will be empty after short time. Nobody say that you will be able to use battery 400 cycles only. Maybe you will be lucky and the battery will have longer life time.
My Tecra M1 is about 4 years old and still working with original battery.
Your question is pretty unusual and I am really interested about further comments.

Battery Cycles and "Sleep Cycles"

Last week my battery died on me, but couldn't get a replacement on my Applecare because i'd gone over the maximum 300 charge cycles. Not a a happy bunny but it's one of them things, and forked out for a new one.
Now, i was wondering if there's such a thing as sleep cycles.
I.eis there a maximum number of times i can put my my macbook to sleep and wake up again?
I'm sure it's a large number and according to the customer service advisor at Apple, 300 for battery charges was a "large number" so i'm thinking, 'am i edging towards this unknown figure and then one day discover my macbook doesn't wake and be told "x number of sleep/wake up is a large number and you've gone over our max threshold and so do one"'
Many thanks

The issue you experienced with your battery is due to normal wear on lithium ion/polymer batteries. It's not that Apple set an arbitrary number of cycles and said "We won't replace it after that". The primary measure of the life for a lithium ion/polymer battery is measured in cycles. The actual number of cycles can vary based on a number of factors (the newer machines with built in batteries are spec'd at 1000 cycles). After you reach that level, battery performance will slowly degrade... but it is possible to just experience flaky battery behavior at any point after the recommended cycle cap. You can prolong the life of your battery by limiting how often you run the machine using the battery. The more you can run the machine while plugged in, the longer the battery will last you. A battery cycle is a measurement for a full charge and discharge of a battery. Rechargeable batteries have a limited number of times that you can charge/recharge them. You just used it up.

Will resetting the MBP also reset the battery cycle count?

Hi All,
I recently purchased a used MBPR (Late 2012) model.
When checking the battery cycle count, I noticed that it says 2.
I am not sure if the original user ever reset the computer, since I noticed he left couple personal files on the computer when it arrived.
I was wondering if anyone can tell me if resetting the Macbook Pro to factory setting well also reset the battery cycle count.
Thanks,

Welcome to Apple Support Communities
If you reset the MacBook to factory settings, battery cycle count stays as it was before. Note that you have the same battery, so the only way to reset the battery cycle count is to install another battery

My battery cycle is at 755

My battery cycle is at 755 and my battery max life is 2 1/2 hours now. I have over a a year left on my extended warranty, is this an issue? I can't just buy a new one since it is built in. If my battery runs out of juice before I can plug it in, it just shuts off from now on. I then have to reboot it. It then tell me the date is set to December 1, 2000 and the time is Sunday at a random time. I then have to reconnect my router to it aswell.

Call Apple and ask.

Battery cycle is not zero.

I got new MBP i7 17" CTO model.
As I checked battery cycle count, it is 1, not 0.
I knew brand-new product should have cycle count 0.
Is this not new, i.e., refurbished or exchanged one previously?
Thank you.
Best Regards,
ed

I haven't checked every battery in my Macs when they were new, but the ones I did check never said zero. I imagine that their Quality Control department would want to test every battery through at least one charge cycle before shipping them to customers. Possibly during the standard burn-in period that I assume Macs still go through before they leave the factory, where the machine is run for a while to make sure all parts are functional.
I bought a "new" non-Apple battery for a MacBook Pro, and it had 3 cycles on it. I still think that's reasonable for quality control testing. I was told it won't even reach proper calibration until you get to cycle 5 or so.

120 Battery Cycles in 73 Days!!!

' AHEM!!! <Slightly sheepish look as he addresses everyone...>
' Ah... Yeah... So... I, uh, picked up my 17-inch unibody on the afternoon of the 30th April. And, well, checking my battery cycles the other day (just out of curiosity you understand?) I noticed the triple-figure count. And choked.
' After clearing my windpipe and resuming normal breathing, I decided to do the math. What this essentially means is that I've managed to average a charge and a half a day, every day, since getting it!!!
' Now, to an extent I can understand it... I'm in I.T. and work on it or through it essentially whenever it is I'm working - which means a lot of overtime too. And sitting in the position I'm in - thousands of kilometers from home in another country - it's also my primary piece of entertainment kit in the meantime. Annnnd I do tend to go everywhere with it - which includes picking it up to accompany me even when I just head outside for 5 or 10 minutes for a smoke for example.
' It is on-and-off of the power cord all day as I move in and out of places doing whatever.
' I just wasn't quite expecting triple digits. A cycle a day I would swallow or believe no problem. The plus-50 percent is a bit of a surprise.
' So. Anyhow. What do y'all think then? Should I offer my services to Apple as a battery stress-tester or something? Might as well get something out of the fact I'm likely to be the very first sealed-battery MacBook client to need a replacement due to usage and not some kind of fault... <Grins>
' Anyways. Just thought I'd share!

' W-O-W!!! Soft Reset - dude - I bow my head in admiration! <Grins>
' I see the first box you mentioned is pretty close to my average. When I first did the math on mine it was 1.57xxx charges a day...
' But 2.6 charges daily??? ****! I am suitably impressed!!! I know there is always someone, somewhere, that is both above and below one in any situation or circumstance in life - but I didn't expect to get a reply to this thread so quickly by someone trouncing me. Hehe. :-D
' Of course I couldn't agree more about your statement re. this stuff sometime making for good / interesting discussion. That's primarily why I started this thread really...
' Just out of curiosity, could you share with us what make / model / year / etc. each of those systems you mentioned happens to be?
' Oh - and what is it you do with 'em that makes for the sort of battery-usage-profile you've shown?
' Looking forward to your, and other people replies!!!

I already have 590 battery cycles.80 % capacity. the MBP is only 1 year old. is this healthy? any tips?

i already have 590 battery cycles. the MBP is only 1 year old. is this healthy? any tips? Im already at 80% capacity.

battery cycles dont mean anything except in the old age of the battery
short term abuse kills a battery, NOT battery cycles.
General consideration of your MacBook battery
Contrary to popular myths about notebook batteries, there is protection circuitry in your Macbook and therefore you cannot ‘overcharge’ your notebook when plugged in and already fully charged.
However if you do not plan on using your notebook for several hours, turn it off (plugged in or otherwise), since you do not want your Macbook ‘both always plugged in and in sleep mode’.
A lot of battery experts call the use of Lithium-Ion cells the "80% Rule", meaning use 80% of the full charge or so, then recharge them for longer overall life. The main quantified damage done in the use of Lithium Ion batteries are instances where the internal notebook battery is “often drained very low”, this is bad general use of your notebook battery.
A person who has, for example, 300 charge cycles on their battery and is recharging at say 40% remaining of a 100% charge has a better battery condition state than, say, another person who has 300 charge cycles on their battery and is recharging at say 10-15% remaining on a 100% charge. DoD (depth of discharge) is much more important on the wear and tear on your Macbook’s battery than the count of charge cycles. There is no set “mile” or wear from a charge cycle in specific. Frequent high depth of discharge rates (draining the battery very low) on a Lithium battery will hasten the lowering of maximum battery capacity.
All batteries in any device are a consumable meant to be replaced eventually after much time, even under perfect use conditions.
If the massive amount of data that exists on lithium batteries were to be condensed into a simplex, helpful, and memorable bit of information it would be:
1. While realistically a bit impractical during normal everyday use, a lithium battery's longevity and its chemistry's health is most happy swinging back and forth between 20% and 85% charge roughly.
2. Do not purposefully drain your battery very low (10% and less), and do not keep them charged often or always high (100%).
3. Lithium batteries do not like the following:
A: Deep discharges, as meaning roughly 10% or less on a frequent basis.
B: Rapid discharges as referring to energy intensive gaming on battery on a frequent basis (in which case while gaming, if possible, do same on power rather than battery). This is a minor consideration.
C: Constant inflation, as meaning always or most often on charge, and certainly not both in sleep mode and on charge always or often.
