Full Charge Capacity

What should the full charge capacity on the Air be?

This is normal. You will see some fluctuation around the number, it's nothing to be worried about. Mine has fluctuated between ~5100 and ~4900 with it most of the time around 4980.

Why is the full charge capacity of my MBPR 13 Mid-2014 only 6175?

It's only a week old.

AZBRONCOZFAN,
I have the same model MacBook Pro as you. When our batteries were new, they had a full charge capacity of 5770 mA·h; but the batteries’ full charge capacities decrease over time. Since your battery currently has a full charge capacity of 4577 mA·h, it’s at 79.3% of its original capacity. Because it’s below 80% of its original capacity, Apple would consider it “consumed”, and would recommend that it be replaced. However, if you still find it perfectly usable in spite of its reduced runtime, then it’d be fine to keep using it.

What is the Full Charge Capacity showing for your 11.6 MBA

Mine started out at around 4675 and is now at 4539 with 16 Cycles. I'd like to see if I'm in the ballpark and if not, what the users with higher capacity are doing: charging, conditioning, etc.

Q: How can I have a 'Good' Battery Condition instead of 'Normal'? I've seen a lot of other users 'Health Information' and theirs says 'Good'.
I've seen it displayed both ways over the years..... depends on where the users are reading it, from the About this Mac, or an application like Coconut Battery. I use iStat Pro and About this Mac. As long as it says Normal I'm happy

What is the macbook pro 15 mid 2014 Full Charge Capacity(mAh)?

Say online different numbers from what I have..

Also see your other post on the same subject in the MacBook Pro forum:What is the macbook pro 15 mid 2014 Full Charge Capacity(mAh)?

Cycle count verses full charge capacity.

My battery on my mackbook says to service battery. Now I know the cycle count is high but it seems to me that the full charge capacity is only about 50%. The macbook is about 2 years old but I would have thought I could have gone longer with the battery since the charge capacity is still pretty good. So, which is better to go off of, cycle count or full charge capacity, and from looking at the specs below does it appear as though I will need to buy a new battery? Thanks..

Nonsense. The battery will actually last longer if it gets used. If it never or is seldom used, then it will die an earlier death. I see nothing wrong with what you are doing.

Is 5232 mAh Full Charge Capacity Normal?

Ok so I bought my macbook pro in february 2011, the new 2011 basic 13" model. I have been having tons of problems since, such as my battery life seems to be terrible, random freezing and lagging, I only really use Mail and Safari and it often freezes and lags especially when I have an email coming in it will completely freeze Safari and I will have to restart my computer because everything will freeze. I was told by apple everything is fine…of course.. and I was also told it was my fault because I have smc fan control installed.. Please let me know what you think of the situation and what I should do…
My main concern is that my battery full charge capacity doesn't seem to be normal, >> Full Charge Capacity (mAh): 5323 < Is this normal?

download cocnutbattery from http://www.coconut-flavour.com/.
With that you can easily see age of your mac, the design capacity of the battery and the number of cycles.
And the reason for freezing and hanging and high temperature of the cpu or gpu is not the battery:
Start Applications/Utilities/Activity Monitor, choose <all processes>, click the %CPU column and see which process "eats" the cpu, say with more than 50%.

MacBook Pro Retina late 2013 out-of-the-box Full Charge Capacity (mAh)

Hello! Can someone tell me what is the default value of Full Charge Capacity (mAh) parameter for MBPr 13 late 2013?
I suspect I have a battery capacity severely degraded, though I have only 42 charge cycles.

Make sure Power Nap on battery is unchecked.
Go to System Preferences.
Select the Energy Saver button.
Make sure the Enable Power Nap on Battery Power is unckecked. This will be located under the Battery tab in Energy Saver preferences.
Also, try resetting your SMC.

Approximate Full Charge Capacity?

What's the approximate Capacity that a macbook battery should have?
mine reads:
Full Charge Capacity (mAh): 5273
-

That is not bad. The battery is rated at 5200 mah. So your a little above. Don't be surprised if your mah goes up a little with proper care. Below are some links and other info the are good to know about the MacBook and it's battery.

You should calibrate your battery at least every month or two. I do mine every other month and have had no problems. Look here and here for some good tips about battery care.

6837 Full Charge Capacity macbook pro 13inch retina display good? Only after having it a few days...?

I'm a noob when it comes to this stuff. But I got my MBP a few days ago and didn't do any research on maximizing battery capacity. Now it's already at 11 cycles. I can't seem to find the normal full charge capacity for my MBP, but is 6837 within Apple's specs? And furthermore, do can people tell the % of the full charge capacity just by looking at the icon on the top right? Because I see some people saying their battery charges up to 102% or 98%...and I can only find "Full Charge Capacity," under the power section. And one more question, since I'm supposed to leave my MBP plugged into an AC power source whenever available, does that include night time, when I'm asleep and my MBP is off? These might be dumb questions... but I'm asking them anyways. Want to keep this baby with me as long as I can :3

Yes. I keep mine plugged in whever a power outlet is available, at night when im asleep even if it is off. But I do let it run very low on battery power a few times a month to keep the battery juices flowing.

Does allowing the Battery to drain to 0% depletes full charge capacity?

I bought a Macbook pro 17-in intel core 2 duo 2.4Ghz from the Phiippines on July 10, 2007 and brought it to Ireland couple of days after. Later, I upgraded to leopard 10.5.2 with 4 Gig memory. Auto updates have been installed since its first use. The only problem I encountered (except for some Safari quitting unexpedtedly) was in the battery.
Here is the record of my MBP battery use:
Battery information
Battery : MBP 17in Rechargeable Battery
Model: A1189 10.18V 68Wh
Serial: 6 _ _ _ _ _ DVYF1A
My Battery practice:
- I wait for 5% remaining charge before I plug the charger
- At several occasions I forgot to plug the charger before remaining charge goes to 0%
- I usually unplug the wall charger as soon as full charge is indicated.
- I sometimes leave the wall charger plugged for several hours after green light shows.
- I use my MBP for an average of 12 - 14 hours a day. At times I dont shut it down and just allow it to go to sleep mode.
- Calibrated about 10 times.

318 (at 3908mAh or 53% remaining charge MBP suddenly shuts down)
318 (MBP shuts down if wall charger is unplugged) Tried calibrating and resetting SMC but did not work.
I then checked if my MBP is still covered by the one-year warranty despite more than 300 battery cycles, no bulges present at apple website https://selfsolve.apple.com/GetWarranty.do (here you have to enter your MBP serial number)
I brought my MBP for check up here in Dublin, Ireland and indeed the problem was the battery. They replaced my battery with a new one without cost.
Thanks Apple my new battery now has a Battery Health of 100% with the following initial cycle records:
Battery Cycle Full Charge Capacity
1 (33% remaining charge as soon as I received it) 6810 mAh
1 (I then used the remaining charge up to 1%) 6726 mAh
1 (full charged) 6810 mAh
1 (full charged) I let it rest for few hours then checked 6879 mAh
2 (full charged) 6879 mAh
3 (full charged) 6876 mAh
4 (full charged) 6830 mAh
5 (full charged) 6845 mAh
5 (full charged) I let it rest for 1 hour then checked 6868 mAh
6 (3% remaining charge) 6829 mAh
I forgot to plug the charger (battery drained to 0%) 6492 mAh
Notice the sudden drop of full charge capacity in cycle 6? How do I recover the lost charge capacity? Does letting the battery drain to 0% depletes its full charge capacity?

The short answer is that yes, completely draining the battery has a slight negative impact on full charge capacity. The full charge capacity does fluctuate a bit over time, but the general trend is downward no matter what you do - there's a continuous chemical reaction occurring in the battery, with a finite life.
However, I note that you state +I wait for 5% remaining charge before I plug the charger+; if you are doing this because that is what you need to do, i.e. you do most of your work away from a power source, fine. But, if you are doing that because you believe that's best for your battery, that is incorrect. The 'old' NiCd batteries performed best with full discharge and full charge. The 'newer' Li-based batteries do not have this requirement, and in fact perform better over time when used frequently but 'lightly', avoiding full discharges (except for the occasional battery calibration, which allows the OS to more accurately determine the time to charge and discharge).

Full charge capacity is not shown in diagnostics t...

After i got last update used my phone couple of days and as batery life still seemed too low i decided tro reset my phone. did the reset and first thing i noticed diagnostics tool was missing form apps menu.
so then i synched my phone downloaded some apps and decided to check if reseting had any effect on my batterys full charge and discharge .
accesed diagnostics via ##634# but it only shows Vats and curent discharge
theres not even line for Full charge capacity and current cappacity.
how can i check it ??
wihtout reseting my phone again ( alredy had to redownload all apps and resynch and relink my contacts 3 times - 2 of them after Noki doen hard reset on my phone )
thanks

weirdliy enough after newest update (1070.20) or similar .. i stil had normal diagnostics in my menu but only AFTER i did reset of my phone it disapeared and acesing it by ##634# it doesn't show full charge .
i spoke to Lumia representaives at one of the shopping ceters about this .. they seem to be just as perplexed as i am...
the thig that makes me wonder is .. Mokia says .. if your battery full charge is blah blah ...they will replace your phone....but does this seem sthat theres more faulty phones than they think??? and the3y removed full charge display cause of that?
i already took my phone to nokia care center twice .... but they didn't change it nor they improved battery life ....
7am of charger - with minimal usage ( mostly checking battery status )13pm battery saver status ..back on charger take it of charget at around 8pm.. no usage just standby ...6h later 41% left time since last charge 6hours 2 hours left
exuse me??? that's after twice i got my phone to nokia ? and they fail to find the problem ....
and after update i noticed on standby discharge is 6% an hour on standby where before update it used to bre 4% an hour whinch aint good either

Information: Update BIOS and Battery Firmware to ensure full charge capacity

Is your system’s BIOS and battery firmware updated to the latest level?
If not, you may not be getting the maximum capacity and run time from your battery!
Lenovo’s engineering team released updated BIOS and battery firmware in July that is applicable to customers who have ThinkPad models:
X100e, L410/L510, L412/L512, SL410/SL510, T410/T410i, T510,T510i, W510 or ThinkPad Edge, 13, 14, or 15 inch units.
Customers who use Lenovo ThinkVantage Toolbox would have received a notification and opportunity to apply this update, and Lenovo’s ThinkVantage System Update tool would also identify and apply these updates.
If you aren’t using either of these tools, and have one of the systems above, please follow this link to our support site. You can learn more there, and download and install the updates specific to your system.
Probably also worth mentioning, is an earlier tip applicable to X200t and X201t tablet users who have 8 cell extended batteries. This technical tip and related BIOS updates ensure these batteries properly charge to their full capacities, and resolves a particular symptom where the battery would stop charging at less than 50%.
Source Lenovo Blogs: Update BIOS and Battery Firmware to ensure full charge capacity
Recommendation before updating bios:
- detach all devices from you system
- undock your system, if docked
- start from a cold boot. (shutting down the system completely, wait 15 min, start up again)
- if possible, upgrade with a cd-rom drive

The unit was purchased on Saturday and right out the box it had an FCC of 5618. After the first full cycle (condition) the FCC read 5542 and and now it's gone down even more. When I was at the Apple store they had 4, 13" MBP demo units and they were all scattered between 5300-5700 with all less than 5 cycles.
I think your battery is fine, from what you've said. I also wouldn't read too much into the 3rd party battery health monitoring tools, from experience what they judge as "95% of full charge capacity" is typically not entirely accurate.

Full charge capacity (mAh):5261- 13" MBP June 2009

Hi
How much should be the "Full charge capacity" for a mid 2009 13" MBP.
Mine is "Full charge capacity (mAh):5261".
Is there any Apple link that officially lists the capacities of different type of batteries?
Any link/suggestion/opnions please.
Thanks

The tech specs ( http://support.apple.com/kb/SP541 ) for a MacBook Pro (13-inch, Mid 2009) says you have a "60-watt-hour lithium-polymer battery". The battery voltage is approx. 12 volts so 60/12=5Ah or 5000mAh would be the rated capacity of your battery. Everything appears fine.
