My battery capacity decreases per charge!!!

Hi guys I need help, I am very frustrated about this matter , This is my first macbook pro retine late 2013 the latest one out yet 4gb ram baseline model with the dubal core i5. I started playing LOL or League of Legends an online game a few weeks back.
When I did start I was completely hooked and played multiple hours even with the battery charger plugged in. The battery lost its total capacity from 6300 its about 6200 then it fell 6150 ok then I statred carying ok I LOVE MY MAC AND ITS BATTERY.
So i went like ok i will play max 40 mins per day, fine huh 1 time per charge cycle make sure the charge cycle is 20 hrs long I have been trying to do this more or less BUT EVEYTIME I PLAY THE GAME EVEN IF THE CHARGE drop is only 30% my total battery capacity drops.
I am checking this through MULTIPLE apps and every time i play the drop is bloody 0.5 percent and i  CANT TAKE IT and when i dont play on a chrge cycle there is NO DROP IN THE OVERALL capacity.
Note i take soo much care when i pay i charge it to 100 and keep it ice cold when  i play and its not plugged in. Any advice are the apps wrong is my capacity decresing are macs not meant for gaming or if i conture down this path will i have to eventully replace my battery just any adivce or thoughts on this matter will be VERY APPRECIATED!!!

When Taxing the system, Running it Hard as most all games do, it will draw power from both the AC charger and the battery at the same time.
The AC charger Apple supplies is not large enough to do both Power the system and charge the battery, or even keep the same charge on the battery, when the system is working hard.
As to the overall capacity of the battery that will go down with the increase of charge cycles.
What you are seeing is completely normal for all Mac notebook computers.

  • [Enquiry] Battery capacity decreased

    Product name: HP ENVY Sleekbook 4

    Hi there,I would like to ask about my battery capacity.
    Please take a look on 2 screen-shots here.
    [IMG]http://i.imgur.com/QGbf474.jpg[/IMG]
    [IMG]http://i.imgur.com/1arYOS2.jpg[/IMG]
    Both of screen-shots were taken in same day but different time.
    As you can see,my battery capacity mah is decreasing from time to time.
    It made me worried,I'm afraid soon my laptop can't hold any longer at outdoor without external power.I brought within a month,there is no doubt if my battery age is old from the time of manufactured
    Before I post,I have searched few article on internet,I discover something called battery calibration,but I'm not familiar with it.I'm here to look whether any solution to increase my battery mah,please guide me.

    3602 mAh down to 3587 mAh is within the margin of error for measurement. About 4 tenths of one percent. I don't see any decline in the capacity of the battery. One screenshot is showing it fully charged and one is showing it at 87% charge. Maybe I am missing something but where do you see that the capacity has declined to any significant extent?

  • Battery Capacity decreasing rapidly

    I have a new 11" Air, and i have noticed something very concerning.
    The capacity of the battery (the maximum amount of charge it can hold) is dropping rapidly.
    In the 3 days I have had it, it has already dropped to 97%.
    It charges fine and lasts as long as it should, but the max capacity it can charge to is dropping so rapidly that it'll be down to zero in 3 months!
    I am using System Profiler/Power to interrogate the battery, and if I compare it to my MacBook Pro 13, the difference is stark.
    The MBP13 after 7 months of use and some 50 charges is still showing around 100.2% capacity - in fact, it has hardly budged at all since it was new.
    The Air was at about 99.5% when I first powered it on, but it is dropping very fast.
    Any ideas?
    Shame, otherwise i love it!!!

    Hi,
    hmm.. if you dont mind, I suggest you to carry your power adapter with you and plug it in to any power source when you start booting your MBA to prevent your MBA from using the power form the battery. This will greatly reduce the cycle count. I think the cycle count is more important than the health because Apple wrote a software to monitor the health based on the cycle count. Meaning, the health of your battery may in fact good, but the cycle count is, say above 300 and thus software ask the owner to change the battery.
    If you think that this way may work for you, remember to calibrate your battery every 3 months.
    Hope it helps.
    Cheers.

  • Battery percentage decreasing while charging!

    Preface: Please forgive my technological ineptitude in advance. I am completely computer illiterate and have embarrasingly little tech vocabulary.
    Okay. Help! While my MacBook Pro is plugged in and charging, the battery percentage is going DOWN instead of up. Yikes. If I stop using the computer, close it and let it charge, the battery percentage goes up when I check it after 20 minutes or so. As soon as I start using it while it's still plugged in however, the battery drains (goes down even though it's plugged in). I've pasted the System Report on Power below (I have no idea what any of it means), the recommendation was from another topic forum. Does anyone know what is happening w/ my laptop? It should also be noted that this is a brand new charger (60W MagSafe Power Adapter), but was still happening before with my old charger before it died (the magnetic piece detached from the part you plug into the computer). Also, it seems to be getting really hot (the new one AND old one!) Thank you for your help!!!

    This is normal. When cpu/gpu intensive activities are run, sometimes computer

  • Battery level decreases when charging ?

    I plugged my macbook pro in to charge. It charged all the way up till ~90 something percent. In terms of duration, it said that it would finish charging in two minutes. Then 4 minutes.... 6 minutes. Then I decided to turn it off.
    Now that I have turned it back on it is only at 88%.
    Weird. Everything seems to work ok.

  • Battery health decreased rapidly after charging problems.

    Hy a few weeks ago the health of my mid 2010 MacBook Pro was still 79% which is normal since it has more than 1000 cycles.
    Then following incident happened:
    My battery was almost discharged, 30% or so, so I connected it to the AC power. After a while I wanted to see how much it was charged but the indicator in the corner still indicated the same 30% or so, only when I disconnected it it changed to something in the 80% range. I used my computer for a while like that and I noticed that the battery indicator was not chaning. Only when I connected or disconnected the AC power did it update.
    I decided to reboot the machine and this solved the problem. I recently noticed however that my battery health now dropped to 63% which seems very much in a short period of time.
    I know that normally charger will deliver less current to the battery when it is near 80% in order to prevent overcharging and maintain battery life as much as possible. I wonder however if the drastic decrease could be because of the power management thinking that the battery was only partly charged and thus delivering to much current to an almost full battery? If this is the case do you think that Apple would intervene for the costs of a new battery? I know I would have had to replace it sooner rather than later but this does change a lot I think. My computer is not in warranty anymore and I don't want to pay 49€ for one intervention. There are also no official Apple stores in Belgium and the authorised resellers really don't offer the same service.

    sweex,
    since your battery has over 1000 cycles and has 79% of its original full charge capacity remaining, Apple considers your battery “consumed”; they will not intervene for the cost of a new battery. It’s entirely your decision when to replace your battery, but irregular charging results are to be expected for as long as you use your present battery.
    If no Apple-authorized service center in Belgium offers the option of changing the battery, then you should let Apple know so that they can find an organization who will do so. I don’t know where you are in Belgium, but this search around Brussels shows seven different Apple-authorized service centers which all claim to service Macs, and the one in Aalst is noted as being a Premium service center.

  • Since I upgraded to iOS 7.0.4 on my iPad 3, battery capacity has drained almost 10%/hour without any use of the device. Prior to the upgrade, the battery charge would hold during periods of inactivity. What can I do to solve this significant problem?

    Downgrading isn't supported.
    You can poke around in the settings. There's a lot of stuff defaulted to on that you may not need, such as notifications.
    You can also look into background app refresh and background app updates. They can be running in the background and drain your battery.

  • Battery Capacity And Charging

    My MBP's battery has an original battery capacity of 6300mAh.
    When fully charged its capacity is at just under 6800mAh.
    I guess this would be considered overcharging; could this cause problems of any kind?

    My replacement battery started with just under 6800 mAh, and over time drifted downward (which is normal) then stabilized (at around 91% health ±5%, where it's remained since about cycle 30). While it's above 6300 mAh, iStat and CoconutBattery will report health as 100%.
    As Kappy stated, the 6300 mAh value (rounded up from 6296 mAh, actually) is a nominal value, calculated from the wattage and voltage specifications of the battery. Individual batteries will vary, with many initially exceeding that calculated value.
    Bottom line, what you're seeing is normal and nothing to worry about.

  • MacBook Pro Mid 2010 Battery Capacity

    I've read a few threads about this, mostly about battery capacity rapidly dropping after an install of ML. I installed ML when it first came out, and just noticed the drastic decrease in battery life about 3 weeks ago. My capacity could have potentially been dropping since I installed ML (and I just now noticed it), or it may have just started a couple weeks ago when I noticed. I'm not sure.
    Either way, my MacBook Pro (Mid 2010) now has a battery life of less than an hour, even with extremely light processor load. I contacted Apple about this, and the tech said that the battery was rated for 1000 cycles. I'm currently at 220, and my battery capacity is a pathetic 30%. He said that since I wasn't under warranty, there was nothing they could do besides replace the battery - which I really want to avoid since I'm a broke college student.
    Is there anything I can do here? I understand that I'm not under warranty anymore, and this wouldn't be a problem if my battery was degrading normally. However, getting 1/5th of the recommended battery life is pretty sad. I've read that doing a clean install of Mountain Lion/Lion might help. Is there a way I can do this without having to back up all my files? I don't have an external hard drive or anything.
    It seems this is a common topic in these forums. Any help or links to solutions would be great. If this is answered in a similar topic, I'll gladly delete.

  • After software/firmware UD, battery life decreased significantly+overheating problems

    Specs of my laptop:
    13 inch late 2011
    2.4 GHz Intel Core i5
    4gb 1333 MHz DDR3
    Mac OSX Lion 10.7.5 (11G63)
    Hi, a month or two ago I did a software/firmware update (the thing that automatically pops up once in a while and asks if you want to update). Before the update, I was getting 7-8 hours running safari on a bright level (more than half) which was awesome!
    Anyways, after I did the update, my battery life decreased significantly. If my brightness was at half, I got around 2.5 hours MAX. If I ran word and safari it wouldn't even last two hours.
    Along with the horrible decrease in battery life, my laptop now gets really hot, really quickly, even if I'm only running safari on a low brightness. Sometimes the fan vibrates becuase it's working so hard...it's NEVER done that before.
    I took it into the Apple store 'genius' bar, since I still have the warranty and the person that helped me offered no resolution. He told me that my battery still has life and didn't know why my laptop did this, laughed...and then dismissed me (rude). haha
    system report of the battery:
    Firmware Version:          201

    I'm not sure what any of this means, but the 'genius' told me my battery still had a lot of life.
    I just want the battery life back.
    Does anyone know what's going on and how I can fix it?
    Thank you

    Hi, thanks for your advice. I just tried resetting and it worked momentarily (battery life improved, fan stopped making so much noise) UNTIL I put my computer to sleep and opened it again... when i first reset, battery life said 5:48. The fan was fine until I put it to sleep (closed the lid and opened five minutes later). Now it's heating up again and the fan is going crazy (making that buzzing noise), battery life is at 2:40 on same display brightness (half). I only have safari open....
    Is there anything else I can try to do? Not sure why this happens after I put it to sleep. I don't want to have to reset my computer every single time I open it.
    thanks
    EDIT: after posting this, not even five minutes later my battery time dropped to 2:07 and is funneling down as I type.

  • Concerned about falling battery capacity on rMBP

    Hello all, I'm starting to worry a bit about my battery capacity vs design capacity on my retina macbook pro 15". It's a early 2013 model that I bought in July. I know that apple guarantees the battery will have at least 80% of it's design capacity after 1000 cycles, but I'm worried mine is going to fall far short of that. Here's my coconut battery info:
    As you can see, I've only had 60 cycles on the battery, the computer is barely half a year old, and it's already down 6%, under 8000 mAh. Should I be concerned/take it to the apple store? I know they won't replace my computer since I'm far outside of my 14 days, but still wondering if they'll do something. Will they even do anything before the battery falls below 80% design capacity?
    I waited to post because I know battery capacity often fluctuates from 5% below to 5% above design frequently and will go up and down with use, but mine has steadily decreased, and has never increased. Every time I check coconut battery, it's 10-50 mAh lower than it was. My macbook does stay plugged in a lot, but I also make a point of using the battery at least once a week to keep the electrons flowing, and most weeks it gets off the charger more like two or three times. Often the battery will get used down to at least 50 or 60 percent before it gets plugged back in, sometimes even as low at 15 or 20 percent. I've tried draining it until it goes to sleep and then letting it charge to full again, but it didn't change anything. I didn't think it would, since lithium based batteries don't suffer memory issues, but I thought maybe it was just an error in measurement by the system.
    Speaking of that, I did reset the NVRAM/PRAM and the SMC (multiple times). Only one of the times I reset the SMC did the light turn orange and then charge more, but it didn't change the max capacity number at all.
    I see a lot of people posting their cocunut results/system information screen and finding they actually have above design capacity. Did I just get a lemon battery, or is it because I have it plugged in so much?
    Thoughts? Thanks!

    Apple guarantees that if your battery is well taken care of and not abused,  however your battery looks fine.
    You state: ~ As you can see, I've only had 60 cycles on the battery
    Cycle counts dont account for much.  People (some) leave their macbooks always hooked on power and worse still in sleep mode and on power and this can ruin a battery in "50 cycles", ergo it means little.
    As for the 5% power fluctuation this means absolutely nothing since charge is just an estimate and the 5% is within that range.
    Information:
    Bad discharging or battery use conditions:
    Heat (due to environmental conditions or due to rapid discharges from heavy use = gaming / video editing)
    Rapid discharging of the battery frequently causes chemical changes over time in the battery leading to decrease capacity and resistance of current flow.
    The very worst use of your battery is often draining the battery very low, and worse still letting it remain in such a state.
    *Most long-term rapid damage to the battery occurs from discharging it with high loading (gaming) conditions but paramount is avoiding deep and frequent low DOD (depths of discharge) in use.
    Undesirable charging or charged conditions:
    High perpetual SOC (state of charge), where the battery is always or very often connected to charge
    Parasitic loading where the battery is both usually on and charging or worse both always charging and in sleep mode, since this induces mini-cycling of the battery.
    Bad general handling conditions:
    Temperature use conditions when either too hot (95F and above) or too cold (50F and below)
    Storing your battery away with a low charge (40% and less) long-term.
    Considerations:
    Your battery is subject to chemical aging even if not in use. A Lithium battery is aging as soon as its made, regardless.
    In a perfect (although impractical) situation, your lithium battery is best idealized swinging back and forth between 25 and 85% SOC (state of charge) roughly.
    Further still how you discharge the battery is far more important than how it is either charged or stored short term.
    Ultimately counting charge cycles is of little to no importance.  Abuse in discharging (foremost), charging, and storing the battery and how it affects battery chemistry is important and not the ‘odometer’ reading, or cycle counts on the battery. 
    Everything boils down to battery chemistry long term, and not to an arbitrary number, or cycle count.
    Keep your macbook plugged in when near a socket since in the near end of long-term life, this is beneficial to the battery.
    http://www.apple.com/batteries/notebooks.html
    "Apple does not recommend leaving your portable plugged in all the time."
    General rule to remember of Lithium batteries is:
    Never drain them LOW  & dont always/often store them HIGH
    While cycle count is commonly seen to be the “miles” on your Lithium Ion pack cell in your Macbook, which they are, this distinction is not a fine line at all, and it is a big misconception to “count charge cycles”
    *A person who has, for example, 300 charge cycles on their battery and is recharging at say 50-60% remaining of a 100% charge has better battery usage and care than another person who has 300 charge cycles at say 15% remaining on a 100% charge. 
    DoD (depth of discharge) is far more important on the wear and tear on your Macbook battery than any mere charge cycle count.  *There is no set “mile” or wear from a charge cycle in general OR in specific.    As such, contrary to popular conception, counting cycles is not conclusive whatsoever, rather the amount of deep DoD on an averaged scale of its use and charging conditions.
    (as a very rough analogy would be 20,000 hard miles put on a car vs. 80,000 good miles being something similar)
    *Contrary to some myths out there, there is protection circuitry in your Macbook and therefore you cannot overcharge it when plugged in and already fully charged
    *However if you don’t plan on using it for a few hours, turn it OFF (plugged in or otherwise) ..*You don’t want your Macbook both always plugged in AND in sleep mode       (When portable devices are charging and in the on or sleep position, the current that is drawn through the device is called the parasitic load and will alter the dynamics of charge cycle. Battery manufacturers advise against parasitic loading because it induces mini-cycles.)
    Keeping batteries connected to a charger ensures that periodic "top-ups" do very minor but continuous damage to individual cells, hence Apples recommendation above:   “Apple does not recommend leaving your portable plugged in all the time”, …this is because “Li-ion degrades fastest at high state-of-charge”. This is also the same reason new Apple notebooks are packaged with 50% charges and not 100%.
    LiPo (lithium polymer, same as in your Macbook) batteries do not need conditioning. However...
    A lot of battery experts call the use of Lithium cells the "80% Rule" ...meaning use 80% of the charge or so, then recharge them for longer overall life.
    Never let your Macbook go into shutdown and safe mode from loss of power, you can corrupt files that way, and the batteries do not like it.
    The only quantified abuse seen to Lithium cells are instances when often the cells are repeatedly drained very low…. key word being "often"
    The good news is that your Macbook has a safety circuit in place to insure the battery doesn’t reach too low before your Macbook will auto power-off. Bad news: if you let your Macbook protection circuitry shut down your notebook at its bottom, and you refrain from charging it for a couple days...the battery will SELF-DRAIN to zero (depending on climate and humidity)…and nothing is worse on a Lithium battery being low-discharged than self-draining down to and sitting at 0
    Contrary to what some might say, Lithium batteries have an "ideal" break in period. First ten cycles or so, don't discharge down past 40% of the battery's capacity. Same way you don’t take a new car out and speed and rev the engine hard first 100 or so miles.
    Proper treatment is still important. Just because LiPo batteries don’t need conditioning in general, does NOT mean they dont have an ideal use / recharge environment. Anything can be abused even if it doesn’t need conditioning.

    Storing your MacBook
    If you are going to store your MacBook away for an extended period of time, keep it in a cool location (room temperature roughly 22° C or about 72° F). Make certain you have at least a 50% charge on the internal battery of your Macbook if you plan on storing it away for a few months; recharge your battery to 50% or so every six months roughly if being stored away. If you live in a humid environment, keep your Macbook stored in its zippered case to prevent infiltration of humidity on the internals of your Macbook which could lead to corrosion.

  • 2 day old MacBook Pro at 98% battery capacity

    I'm a little bit concerned about the lifespan of my new MacBook Pro's battery. When i recieved the machine i performed a battery calibration as Apple recommends. I then charged and discharged again. I was concerned when Coconut battery (not always accurate) told me my battery was at 98% total capacity. Is this normal? after 2 cycles my capacity is down 2% .
    I'm surprised because I've never seen this on my old iBook which usually loses 1% capacity per month.
    I've read that these lithium ion batteries have a memory, that the cells not being used stop functioning because they are not needed. Is this true?
    When at home should i keep the machine plugged in? My iBook used to be fine when i took it to school and drained it, then charged it at night. Opinions?

    More or less, yes, I do. Actually turns 5-days old today and at 97.8% of capacity (5330 mAh compared to 5450 when new) after 4 battery loadcycles. Coconutbattery says this is 97%, but my math is a bit higher at 97.8%. Clearly this rate of decline is not sustainable.
    So my question to you was, did "don't worry, enjoy" mean that in your experience, the initial few percentage points of battery capacity is blown off quickly, but the battery capacity will quickly stabilize to something that is still acceptable?
    My battery on a full charge this morning (day 5 of ownership) lasted 3:50, with display at 50%, no use of the optical drive, Wifi on, bluetooth off, and running Mail, Safari, Firefox, iCal, Excel & Activity Monitor (to keep an eye on things). No work was done in Excel, Firefox or iCal, just Mail & Safari. So, I, too, am a bit concerned about being nowhere near 7 hours. Or 5 hours, for that matter. So, short battery life and losing 2.2% of capacity in 4 loadcycles and 5 days is concerning, and tempting to connect the dots.
