We recharge our battery on the iPhone at least every two days. But how many charging cycles has the iPhone already behind it? With a little trick you can find out without any additional software.
Under iOS 13 you can read the current charging cycle with certain unknown tricks. However, this requires some technical understanding.
This is how you can see the charging cycles of the iPhone
First we open the settings of the iPhone and scroll down to the item data protection. Then we also scroll down until you see the "Analysis & Improvements" field, which we also select. If the field just mentioned has now been called up, the "Analysis data" field comes towards us. Now we see some log files here, but we scroll down here until we get to the last "log-aggregated- ..." and select this one.

In the next step we opened the log file. This consists of source code which we copy. Next, we'll open the Notes app and paste the copied source code. Once we have added the code, we search the source code for “BatteryCycleCount”. There is the number between " “To be observed.

Now you can not only see your battery status in the settings within iOS 13, but also find your charging cycles.
Summary:
- Go to "Data protection" in the settings
- Go to "Analysis & Improvements"
- Click on "Analysis data"
- Scroll to the last "log-aggregated- ..."
- Copy the source code of the file into the Notes app
- Search there for "BatteryCycleCount"
- The value between " “Is the total number of times the iPhone has been charged
The information can't possibly be correct for me. My iPhone is not even 5 months old (12 Pro Max) and has supposedly already had 325 charging cycles. Calculating this down, that would mean that I fully charge the phone at least twice a day. But that's not true. Sometimes I don't charge it at all and it lasts for 2 days. Or I only charge it to 2 or 70%. The display has to be nonsense. At least for me.
That would also mean that, as the writer “Tony” says, after 500 charging cycles the battery drops to 80 percent. Then the phone would be almost junk with 325 cycles. But it still has 100%.
The information should therefore be treated with caution.
OK, if I take the file a day older it comes out with 334.
I don't understand why the latest file only shows 44, but okay.
44? for a 2 year old iPhone? Can never be right.
Great guide, I've been looking for that for a long time. I couldn't mark the entire text with Mark all like Tony. 🙂
Thank you, learned something again! 🙂
Otherwise, this could only be read using programs on the PC. Copying the log file was cumbersome. It was not possible to mark the text using the "All" button. I copied the log file from bottom to top. That was relatively quick.
One could also have mentioned that a battery can go through an average of 500 charging cycles before it reaches the critical 80% mark.
