Battery cycles and percentage left is already at 95%!

I got my macbook air yesterday and it already says that the battery life if only at 95% left 4872mah left
Why does it do that?

I think what he means is the "battery health" shown in istat pro.
I know I let my battery go for a bit today (maybe down to 65%), and after recharging, for some reason my battery cycle count increased from 1 to 4. My charge capacity is 4979 mAh now, I recall it being around 5060 mAh earlier.
This all could just be because it's a new laptop - I'll likely calibrate the battery to see what that does.

    Has anyone had this issue or know of a fix?
    Thanks

    Try this
    Restart iPhone: Hold down the Sleep/Wake button and the home button together until the apple logo appears (ignore the ON/OFF slider) then let both buttons go and wait for phone to restart (no data will be lost).
    Using the phone while charging doesn't create a problem.. I do it all the time

  • Battery Cycles and discharge when plugged in

    Hi all,
    Couple of questions from a newbie unibody MBP owner.
    1) My battery is draining slightly even when I have it plugged in. Over 3 days using it plugged in and shutting down in between, my charge goes from 99% down to 95 and triggers a recharge. Is this normal?
    2) My battery seems to add cycles every time I charge it - even if I've only used it on battery for an hour of plain browsing. Aren't cycles meant to reflect accumulated discharge rather than number of charging events?
    Battery has been calibrated twice since I received it 2 weeks ago.
    Thanks in advance for your help.

    Thanks for your reply Mr Engineer.
    So re the charge cycle, it shouldn't be adding whole cycles to the count each time I only used a small a amount of charge, then recharge. IE - 1 cycle should = 10 x (using 10% of the battery, then recharging).
    Since mine is adding cycles each time I recharge, is this likely to be a software or a hardware(battery) problem, and how do I get it fixed - just call AppleCare?
    Many thanks

  • 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.

  • Battery 79% life after 72 recharge cycles and Amperage -1356

    Hi to all, this is my story, I've bought a macbook pro 15'' on November 2007 and in about 4 months battery was at 50% of life after 92 recharge cycles, after one year from purchase, apple store has changed battery, megasafe and the connector on the macbook, now the situation isn't changed and I have a battery, like in object, with 79% of life after 72 recharge cycles and the Amperage in the information window is (-1356) very strange!!! Why there's a negative amperage? and why my battery works so bad? I always charge the battery when is completely discharged and when i do this the macbook is off, sometimes I use macbook with megasafe connected but in this situation I remove the battery. Can i have a new battery from apple in free substitution?

    Hi alby_mo and welcome to the forums.
    The amperage figure you mention will ALWAYS be negative when running from the battery and be positive when the battery is actually charging.
    Your battery life is not uncommon, (many people only get about 18 months life out of these batteries, I'm afraid) but you are going about the charging process all wrong!
    You should avoid completely discharging Lithium batteries as much as possible, and use them regularly and lightly if possible. Discharging them completely all the time reduces their lives substantially. THis used to be a good idea in the past with NiCad batteries that would develop a "memory" problem otherwise, but it is not so with Lithium batteries.
    The only time that you really need to completely discharge your MacBook Pro battery is when you "calibrate" it, which you should do every month or two. See http://support.apple.com/kb/HT1490 for instructions.
    See http://discussions.apple.com/thread.jspa?threadID=1764220 for a good FAQ with information about how to look after your battery, together with Apple's own comments at http://www.apple.com/batteries/notebooks.ht
    You should stop running the computer without a battery installed, too, for the reasons set out at http://support.apple.com/kb/HT2332. It has little effect on the battery because charging is disabled once the battery reaches 100% and doesn't start again until it has dropped to the mid 90's. Better , instead, to get into the habit of running the computer on battery for an hour or so each day, and just leaving it on the charger the rest of the time, whether you are using it or not.
    The "health" of your battery seems to reduce when the charge gets low because dying Lithium batteries build up increasing internal resistance, which becomes more apparent as the voltage drops.
    You can ask Apple service in Italy (or an AASP) about a free replacement, but I wouldn't get your hopes up. Many people with 2007 MBps are already on their second and third batteries, and Apple generally will only replace them during the warranty period. Some people seem to get lucky, though, and you can't lose anything by asking!
    Cheers

  • 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.

    Guys, i am actually trying using a solution provided by the article shared by dominic23,
    It says "Another option is to get an ionizer to help the atmosphere in the workplace be more conductive and pull charges away from contact surfaces, including yourself."
    So in my home, we have such device that could clean the air using ion, and i am using it in my room...
    Result: BANG!!! The electric shock on my macbook has gone!! I don't really care about physics but somehow it works! You guys should give it a try.

  • Where can I find a new battery with no charge cycles and a full charge capacity of 1430 mAh for an iphone 4S?

    There are horrible reviews on so many battery replacement sites (Amazon comes to mind) where people are buying so-called new replacement batteries and finding that they're had several hundred recharge cycles and won't hold a full design charge.  Can't I get a replacement battery from Apple, or has Apple chosen to abandon it's iPhone 4S customers?  If there's anything on the Apple web site where you can buy a replacement battery for the product, it's not obvious.

  • Is there a way to disable touch on the Helix and get a power management for battery cycles?

    As the title describes.
    I've been drawing a fair bit on the Helix using photoshop but what to find a way to disable touch. I used to be able to do it on my x220t through the control panel>isd tablet settings. Windows 8 doesn't have that option. Please don't mention palm rejection as it doesn't always work.
    Also I'd live to know if there is a battery gauge to show the battery cycle of the helix. I know the battery is in good condition. What i'd like to know is the cycles of both batteries.

    So I have found a temp work-around that does the deed.  I have been using a lot of autodesk sketch, and its bomb if you don't have to worry about your hand touching the screen while you sketch.  Here is how I have been doing it.
    WIN+X >> Device Manager >> Human Interface Devices >> 
    Under this section you will find three USB Drivers installed.  I found that if I desable the second USB Driver, then the touch screen stops working, but the Digitizer still works 100%.  Just re-enable when you want to use the touch again.  I really wish Lenovo had software to take care of this out of the box.  But as I said, It works for the time being.

    After taking a dip in my vest pocket in the washing machine for about 10 minutes, my nearly new 5S spent 5 days in rice and silica gel packets.   It definitely dried out, but there is damage to either the battery or the circuit board because it turns on, and I continuously get a blue screen and it reboots every five minutes for a half hour, and then miraculously, it stays on and works perfectly.  But I wound up having to fork over $700 for a new 6+. because I couldn't stand the rebooting any longer.   I had no insurance, but I do now, Apple insurance, not carrier ins.

    It's normal for health to fluctuate a bit (mine ranges from 86-96%, and has done that for the past 100 cycles or so). But, your fluctuations are a bit wider than I'd consider normal. Keep an eye on it, and if it dips and stays below 80%, contact Apple before your 1 year warranty expires.
    When was the last time you calibrated your battery? That should be done every 2 months or so.

  • I just bought a new macbook pro 13-inch. I ran coconut battery test and it says age of the macbook is 22 weeks. And the battery load cycles shows 4 and battery capacity is 96%. Is this all normal? Does anyone have same issues?

    I just bought a new macbook pro 13-inch 6 days ago. I ran coconut battery test and it says age of the macbook is 22 weeks. It shows 4 battery load cycles and battery capacity is 96%. Is this all normal? Does anyone have same issues?

    "Is this all normal?"
    Yes.
    "Does anyone have same issues?"
    What issues?
    Coconut indicates an approximate battery capacity, and 96% is excellent.  During testing and run-in, the MBP is charged and discharged, and a cycle count of 4 is appropriate.

  • Battery Health and ways to bring it up again?

    I've had my MacbookPro for a little over two months now and 31 cycles on it. However, I have already lost 7% battery health, leaving me at only 93%. I'm pretty sure that this is not good, and that the loss shouldn't be this rapid.
    I'm sure it has something to do with the way I use the computer. I leave it on quite often, which I know isn't a good thing, but had no idea that it would drain the battery like this. In some cases the computer is on for days at a time. I've gotten into a routine where each morning I turn it off for the bus ride to school, where I use it throughout the day. The night before it remains on so that I can quickly check things in the morning.
    I currently use my MacbookPro as a semi-desktop. I have it hooked up to an external monitor, and use a wireless mighty mouse and wired keyboard, which is primarily the reason it's on for such long stretches.
    Now that you have some background as to what I do with the computer I'd like to know if there is any way to replenish the battery health, or if that 7% is lost for good.
    I've read up on this calibrating of the battery business, and I'm going to try it this weekend (can't during the week because I need it fully charged for school each day).
    What exactly does this do? Does it actually replenish the battery health or just determine it's actual current percentage?
    I'm using the widget iStat Pro as my monitor of battery health.
    If any other information is required, I'd be happy to provide it.
    Thank you.

    Full Charge Capacity (which is what the specific battery clocked at the factory when first tested).
    Just a minor correction, but can be significant. Full charge capacity is not "what the specific battery clocked at the factory", it's a nominal value, i.e. a general property of the battery type, not that specific battery. Specific batteries have a range of full charge capacities (when new). In fact, it's not even measured, it's calculated - for the 15", it's a 60 Watt-hour battery (from the specs), and it runs at 10.8 V (printed right on the battery). Thus, with a basic formula (W = V x A), an algebraic rearrangement, and some simple math, 60 Wh / 10.8 V = 5.555 Ah = 5555 mAh (~5500 mAh, which iStat uses as the denominator for "health", although I have read that under Leopard iStat uses 5600 mAh, just a rounding difference). My 17" with a 68 Wh battery calculates to 6296 mAh, ~6300 mAh - my replacement battery actually started with ~6800 mAh in System Profiler.

  • Battery Failure and Kernel Panics. Help!

    Hi all,
    Thanks in advance for your help.
    About a week ago, after I had left my computer alone for two days, it randomly shut off when the meter up top said it had 40 minutes. Then, when it was closed in sleep mode and I opened it, it told me it had to be restarted--which I, through reading the forum, found out is a kernel panic. Since then it has not given me any more kernel panics, however, it consistently turns off at about the forty minute mark. This is what I have done so far:
    attempted to recalibrate the battery, which hasn't worked/I don't know if it really can because it doesn't get below 20% without shutting off. (btw, when I turn it back on, with the plug in, the battery is not dead, it's at around 20%).
    have done the first three steps in the x guide to kernel panics.
    Does this sound like a battery problem, and if so how do I solve that?
    or does it sound like a kernel panic, hardware problem?
    Thank you so much for any help, I desperately want to fix my computer.
    Besos.

    Hi alby23,
    Welcome to the Discussions.
    If your computer is two years old, it's in need of a new battery. If you open System Profiler (Apple menu>About This Mac>More Info) the battery's capacity and charge cycles will be listed. If the Capacity is ~2000 you have less than 50% of a new battery's which is 4400mAh.
    You may be able to solve part of the problem by resetting the PMU. That may get the time/percentage back to a more accurate number. If that doesn't help, get a new battery.
