coconut Battery - Measure the charge current and discharge current on the iPad, iPhone and Mac

The Mac app coconut battery I had you already presented once - as a simple solution to bring back the display of the battery life on the MacBook. However, the software for macOS can do even more! She is extremely helpful if you want to measure what is happening with the battery in the iPhone, iPad or MacBook. To do this, install the app on the Mac and access the data from iPhone and iPad via WLAN (Wi-Fi synchronization via iTunes on the iOS device). I always use coconut Battery when I test Qi chargers because I can use it to determine what electrical energy is actually used in the iPhone's battery. That is more precise than one USB multimeter.

My recommendation: The plus version of coconut battery with all functions

With coconut Battery Plus on the Apple Mac, you can read and process the battery data from iPhone and iPad via WLAN. A useful analysis tool - also for the MacBook battery.

coconut Battery Plus - charging current and discharging current on the Apple device

The app has been around since 2005, and it is currently in version 3.7.2 (as of May 10, 2019). Download, installation and use are possible under the operating system versions from OS X 10.11 El Capitan to macOS 10.14 Mojave. The standard version is free, the plus version of coconut Battery costs € 9,95 including VAT. I have summarized the advantages it brings you in the following table:

Show real values ​​in the Qi charger test

If you have installed coconut Battery Plus under macOS on your Apple Mac, iMac or MacBook, you can use the Plus version to establish a direct connection to the iPhone or iPad via WiFi. You can then access the battery data of the iOS device. These are only updated every 10-20 seconds, but with coconut Battery you get much more accurate values ​​than would be possible with a USB multimeter. You can only measure how much the iPhone is "pulling" in order to charge itself anyway. You never find out how big the discharge capacity of the battery is if you don't use coconut battery.

With coconutBattery you know exactly how power is received by the battery of the iPhone, iPad or Mac or how much power is currently required from the battery. A USB multimeter falsifies these values ​​because part of the current is always consumed by the Apple device itself.

Here are a few tests as practical application examples:

coconut Battery Update for Apple Silicon Macs with M1 processor

I opened coconut battery a few days ago because I wanted to see how the battery status of my Apple Silicon MacBook Pro with M1 processor is. It struck me that "Design Capacity" had a value of 2%. This comes about because "Full Charge Capacity" only mentions 100 mAh. Something that just can't be right because the Apple Watch already has more than 100 mAh - and I think we agree that the battery in the MacBook Pro should be a bit bigger.

A full charge capacity of 100 mAh simply cannot be real, because even the Apple Watch already has over 170 mAh.

A full charge capacity of 100 mAh simply cannot be real, because even the Apple Watch already has over 170 mAh. But in the meantime there was an update of coconut Battery, which addressed this problem.

As soon as I opened the app again, an update window came up that, among other things, advertised "Support for Apple Silicon Macs" as an innovation. So the value of 2% was simply an error in the coconut Battery display, based on the fact that the app did not yet have any data on the new Mac models. So if you ever get strange values ​​in the app, it's best to check whether there is an update that fixes this problem.

With the update of Coconut Battery, M1-Macs now also have the opportunity to disclose something about their power consumption.

Is there a coconutBattery alternative for Windows?

I couldn't find a 100 percent alternative for Windows. There is no program that has the same functions as coconutBattery. One possible alternative that could be looked at would be IBackupBot.

This tool provides information about the battery status of iPhone, iPad or other connected devices. However, this information is not that easy to find, because iBackupBot was actually programmed to back up data from the iOS device. The advantage, however, is: we only need one function, which is available in the trial version. And we find it like this:

  1. Download iBackupBot Trial
  2. Connect the iPhone or iPad to the Windows PC via USB (and now wait a few minutes until the program reacts again)
  3. select the iPhone under "Devices"
  4. right on "more information"
  5. The information about the battery can already be found in the following window

Advantages and disadvantages of coconutBattery

Advantages

  • precise determination of the current flow away from the battery or towards the battery
  • Data about the charging cycles and the battery status
  • updated for Apple Silicon Macs
  • Data acquisition is also possible via WLAN

Disadvantages

  • The data is only updated every 10 to 20 seconds
  • sometimes the radio connection breaks down and no more current data is received

Does CoconutBattery have a log function?

No, it doesn't record any data. The display is also only updated every few seconds, so that an exact evaluation over time would be difficult.

Can you use CoconutBattery without a USB cable (via WLAN)?

Yes, it works. You have to activate the WiFi synchronization for the iPhone on the Mac to use this function. However, you also need the commercial plus version for this feature.

What is the difference between the free and the plus version of the app?

With the Plus version you buy a one-time upgrade that unlocks these features: WiFi support, iOS battery analysis, extended view for iOS devices and Macs, user-defined print templates, notifications.

What does the Plus version of CoconutBattery cost?

The plus version of the Mac app CoconutBattery costs 9,95 euros (as of April 2021).

Does the app also work on Apple Silicon Macs with the M1 chip?

Yes, the app was updated at the beginning of 2021, which has now introduced compatibility with Apple Silicon Macs. The update was available free of charge.

Why is the current maximum capacity higher than the design capacity?

The value under "Design Capacity" is the capacity that the battery in the device should have after it leaves the factory. In the manufacture of rechargeable batteries, however, chemical processes are involved, the result of which can never be 100% predicted. Therefore, in some cases, the current maximum capacity may be higher than the design capacity.

Coconut Battery or Apple's Battery Condition - Which is More Reliable?

If you connect your iPhone to the Mac and check the health of the battery with Coconut Battery, you often get different values ​​than those that you can call up via the "Battery status" option in the iPhone settings. If you want to check it yourself, you can find the battery health this way under iOS:

Settings> Battery> Battery Health

There is no clear statement as to which value is more correct here, but of course there are arguments why one could rather believe the Apple value:

  • Apple has more direct access to device information.
  • The "Coconut Battery" app may not have access to certain values ​​of the battery and must calculate an approximate value.

However, there are also voices who generally see a problem in the fact that the values ​​of both displays can be particularly precise:

  1. Batteries are chemistry and so their condition is always difficult to determine.
  2. Depending on how certain values ​​of the battery are included in a calculation, you can come to different percentages.
  3. Over the years, not only does the capacity of the batteries deteriorate, but also their performance - i.e. the ability to cover a high level of power consumption in a short period of time - is lost. How this is included in the calculation is another question.

Unfortunately, the question of the accuracy of the individual information cannot be fully clarified, but many users swear by the Coconut Battery displays because, for example, they had an iPhone that switched itself off during operation. The battery status was indicated by Apple as 84%, while Cococnut Battery only attested 65% and was therefore probably closer to reality.

What is "High Performance" on the iPhone's battery gauge?

Apple introduced this term at the beginning of 2018 after they got it on the roof because of the supposed "iPhone brake". The "brake" is more of a feature because it slowed down an iPhone with a weak battery to such an extent that no energy peaks can occur, which would otherwise have resulted in the iPhone being switched off.

If you have a weak battery in your iPhone, you will get the following message from the system under the battery status:

The condition of your battery has deteriorated significantly. An Apple-authorized service provider can replace the battery to restore full performance and capacity. Learn more about service options - This message does not indicate a security issue. The battery can still be used. However, there may be more noticeable battery and performance issues. With a replacement battery, you can make better use of your device.

For example, if you have a navigation app on, listen to streaming music, gamble a bit on the side and then start taking photos with a flash, then the battery may have to deliver enormous power for a short time. Older batteries often cannot do this, which is why a protective circuit switches the battery off completely in order to avoid permanent damage.

However, if a battery is still fresh enough to be able to absorb these energy peaks, then Apple speaks of the fact that it still has a "maximum capacity" and consequently the iPhone brake is not activated.

Due to legal pressure, Apple was forced to install an option that also allows the iPhone brake to be switched off manually. So if you think you don't have to take care of your iPhone and want to switch it off spontaneously, you can intervene here yourself.

Coconut Battery, however, does not make any statements about the maximum performance - probably also because the app lacks access to data that the iOS operating system has.

The Coconut Battery Advanced Viewer extracts more data from the iPhone, iPad or Mac.

Coconut Battery Advanced Viewer for Mac and iOS

I just saw that Coconut Battery has a few more features that I haven't tried out myself. There is an advanced viewer, which shows more data under macOS and iOS. It's not just about the battery, but also about the health of the SSD, the date of manufacture, the factory in which the device was built and much more.

The Advanced Viewer can be found by clicking on "Mac Info" in the Coconut Battery window (or correspondingly on "Device Info" for an iOS device) and selecting the "Advanced Viewer" button in the following window.

For example, on my Mac I could get the following information:

  • Name: MacBook Pro from Jens
  • Model: MacBookPro17,1
  • Serial: XXX (shouldn't be displayed publicly!)
  • Model Description: (13-inch, M1, 2020)
  • Manufacture Date: November 2, 2020
  • CPU model: Apple M1
  • Disk:
    • APPLE SSD AP1024Q:
    • Firmware: 2.101.1
    • Power On Hours: 1815
    • Lifetime used: 18%
    • Power Cycles: 214
    • Data Read: 636,76 TB
    • Data Written: 578,52 TB

That is quite interesting information, which is not all bad, especially on a used Mac. For example, I am a little surprised that my SSD has already reached 6% of its life after 18 months. This means that with a 5-year-old Mac with an SSD, you have to expect the SSD to bite into the grass at all times. It's not a good feeling when you keep that in mind.
