What's your battery's full charge capacity?

    And how old is your phone? I recently downloaded a free trial of an app on my Mac that told me how much of the original capacity I have left. Turned out I had 74% of the original capacity left. I have a launch day iPhone 5 so the battery is over a year old. I decided to buy a replacement battery on ebay and replace it myself. Worked out great and only cost me $8 compared to Apple's $79. My new battery is at 96% of original capacity, but I think that's normal for a new battery because my mom just got her iPhone 5 replaced a couple of days ago and the battery capacity is at 98%, so I don't think it's ever actually at a full 100%.

    For those of you who would like to check your percentage, the app is iBackupbot (just get the free trial) and all you need to do is plug your iPhone into your computer and click "More Info". Divide your Full Charge Capacity by your Design Capacity and times that number by 100 and you will have your percentage.

    It's been 9 months since I've got my iPhone 5

    The maximum charge capacity is 1329 mAh while it's been 435 charge cycles which means 93% from original capacity. It's around 0.28 mAh loss per charge

    Mine OK?

    Here is my battery capacity. It dies between 20 and 30% on some days and then other days it'll make it to 5-10%. I bought a replacement battery kit on amazon but don't want to use it unless I absolutely have to. Thoughts?

    I've had the 4S since launch day, and I've already used 1200 Cycles (but I'm planning to get the battery replaced.) It doesn't last a long time anymore b

    I got my 5S on opening day and I have no idea how my battery is doing and I do not really care as long as it gets me though the day with power to spare.:rolleyes:

    No wonder mine lasts about 2 hours...

    (iPhone 5)

    CycleCount: 396
    DesignCapacity: 1430
    FullChargeCapacity: 677
    Status: Success

    That's a loss of 1.9 mAh per cycle. The phone is on charge from midnight to 7am daily for the last 18 months, and has been giving me major issues for about a month now, randomly turning off etc. Any GPS usage seems to just nuke the remaining charge in 3-4 minutes.

    I've ordered an ebay replacement battery kit for £4. Will post result once it's been fitted.

    Thats my iPhone 4S. I replaced the battery over a year ago with the kit from ifixit.com. Its doing well though.

    That's actually not bad at all. I replaced my 4S's battery too about a year ago, and my battery stats are way less..

    Fitted the new battery just now. Was a little concerned as it wouldnt turn on, then plugged it into a charger and still wouldn't turn on, showing the red slice of battery/battery empty image. after about 15 minutes it turned on and below are the stats:

    CycleCount: 0
    DesignCapacity: 1430
    FullChargeCapacity: 1401
    Status: Success
    BatteryCurrentCapacity: 4

    Let's hope it works out better than the old battery.

    Very happy with my battery life!

    My iPhone seems to die all the time. At school, even if I don't use it heavily, it's at 20%.

    Launch day iPhone 5, 84% of original capacity.

    CycleCount: 432
    DesignCapacity: 1430
    FullChargeCapacity: 1197
    Status: Success

    I usually use the battery down to 50-60% over the course of a workday, and down to 20-30% on weekend when I'm out and about.

    Considering I recharge to 100% every night and don't really go out of my way to "caretake" the battery, 84% after almost two years is pretty damn impressive!

    I'm actually seeing something stranger - on a 5S, I'm seeing the DesignCapacity at 1550, but the FullChargeCapacity is reading 1600(!). Could this be a bug in the app or the phone (I'm running iOS 8.0.2)?

    Apple usually provides a bit more juice then the design capacity. All my device bought new were like that as well. So It's normal.

    My iPhone 5s, purchased last December, is at 1201mAh at 77% capacity with 287 charge cycles. Is this normal, or should I take it to an authorised service centre?

    (1201/77)x100=1560. So I think you're putting the wrong one down, you need to put the one that says something like 'full capacity'

    Pretty sure that it's the right one. Battery life used to be 6~7 hours on Wi-Fi, now I can barely hit 5 if I'm lucky.

    Full Charge Capacity 700
    Status Success

    Is that Bad? My Battery flicks around with the charge % alot.

    What about where it says Fully Charged False?

    Time to get a new battery?
