Missing raw data on iOS 10/11/12

Unfortunately, you won't be able to view the following raw data on iOS 10:

  • Battery cycles
  • Battery temperature
  • Dis-/Charge current
  • Removed data from iOS 11:

  • Maximum charger current
  • Removed data from iOS 12:

  • Battery capacity (including wear level)
  • Battery voltage
  • Apple has removed this data from iOS 10/11/12 and there is nothing we can do to bring it back at this point.

    Please don't downrate Battery Life on the App Store, because we have to respect Apple's decision. Most of Battery Life's features still work fine in direct comparison to older iOS versions.

    Family Sharing isn't working

    Family Sharing an In-App Purchase is currently not supported by Apple. Therefore, you won't be able to share the Pro version of Battery Life with your family.

    What are the Pro features?

  • Removal of all advertisements
  • Further Today widget options (only iOS 11 or older)
  • Full Apple Watch compatibility (only iOS 11 or older)
  • I have replaced my battery with a 3rd party high capacity battery, but Battery Life does not recognize the higher capacity.

    Starting with iOS 10, Battery Life is not compatible to high capacity 3rd party batteries.

    Indicators for worn batteries

    Sorted by relevance

  • Your wear level is very high (20% or more).
  • Your device shuts down at a charge of 10% or more.
  • The battery's capacity fluctuates by 10% or more.
  • My battery's capacity fluctuates a lot. Why?

    If your device is on iOS 8 or newer, it is an usual behavior and your battery is probably fine. Depending on the usage of your device (Games, Videos) the capacity may fluctuate a lot (for example from 90% to 95% during a few minutes). Another important factor is the current battery temperature.

    The capacity should, however, not fluctuate more than 10% (see previous question).

    How do I best charge my device?

    Apple mobile devices use a Lithium-ion battery. When operated under normal conditions it is not possible to overcharge the battery. Therefore you can safely keep your device connected to the charger over night.

    The best way to maximize your battery capacity and cycles would involve watching the battery while charging with great accuracy. The battery charge should be kept between no less than 10% and no more than 80%. This is however a very impractical way to use your device and thus we do not recommend it.

    Remove certain cases during charging. Certain styles of cases may generate excess heat, which can affect battery capacity. If you notice that your device gets hot when you charge it, take it out of its case first.

    If you would like to learn more about how your device's battery is charged, there is a document created by Apple available here.

    How can I further improve the Battery Life and Lifespan?

    Apple has created a great guide on this topic. For more information follow this link.

    How does Battery Life calculate the remaining runtimes of your device?

    Unlike other battery analysis tools, Battery Life takes the level of battery wear into account when calculating the runtimes. The runtimes are calculated on the basis of Apple's specifications.

    It is, of course, impossible to predict an exact runtime for your device because the value depends heavily on your settings and usage. Therefore the calculated runtimes should only be used as an approximate value.

    If you would like to learn more about how these specifications are defined, please take a look at Apple's document here.

    My battery's cycles do not show up.

    There are multiple reasons why you can't see your battery's cycles:

  • Your device is running on iOS 10 or newer. See question "Missing raw data on iOS 10/11/12".
  • Your device or battery is new and does not have a fully completed cycle, yet. It will show up after one complete cycle, which may take up to a few days.
  • You have recently replaced the battery with a 3rd party battery. Some 3rd party manufacturers do not sell 100% compatible batteries. Please always make sure to buy a replacement battery from a reputable source.
  • You are running Battery Life on an iPod. Unfortunately, Apple's iPod has some technical limitations compared to the iPhone or iPad and it may be missing some battery data. There is nothing we can do about it.
  • Troubleshooting after a battery replacement

    Did you recently replace your battery and are you now having some problems and/or Battery Life does not work accurately anymore?

  • Unfortunately, some 3rd party manufacturers do not sell 100% compatible batteries. Please always make sure to buy a replacement battery from a reputable source.
  • Question not answered?

    You can always contact us by e-mail or sending a tweet to @BatteryLifeApp. Please try to be as exact as possible and attach a screenshot of the battery raw data so that we can assist you further.
