The battery life of iPhone/iPod Touch series products is about 400 cycles. After 400 cycles of charging, the battery capacity will drop to about 80% of the factory design. So, how can I know how much my mobile phone battery has been used and how is its performance? Unfortunately, the iOS system does not provide the function of viewing battery consumption information. Jailbreak users can achieve the above requirements by installing BatteryDetective or Jinshan Battery Doctor. For users who have not escaped from prison, they can do it in the following two ways: Method 1: Check the data of diagnosis and consumption and enter the setting interface. Choose in turn? General? About this machine? Diagnosis and dosage? , choose after entering? Automatic sending? (Figure 1), it should be pointed out that you must wait until the data is generated the next day before choosing? Diagnostic and dose data? For viewing. There may be a lot of data here, but they are all arranged alphabetically. Find it through what? Logarithmic polymerization? Start with the log, followed by the date. Select the log file with the latest date. These log files are generated every day, but only when the automatic sending option is turned on, so if it is not turned on, it will take a day. Click to open the log file, turn the page to check, stop when you see a bunch of TCP words, slowly turn it up, and see the maxCapacity value, which is the maximum capacity of the battery. Method 2: it is realized by iBackupBot. In fact, no matter whether your iPhone is jailbroken or not and what version of iOS is, we can choose to install iBackupBot. As for whether the software is registered or not, it doesn't matter: connect the iPhone to the computer and open the iBackupBot. By default, only general information such as iOS film, serial number, Bluetooth address, Wi-Fi address and time zone will be displayed on the right. Please click on the blue one? More information? Link, the dialog box as shown in Figure 2 will pop up. What should we pay attention to naturally? Batteries? Bar, here? Design capacity? What should I pay attention to when representing the factory design value of battery capacity, that is, the standard value? CycleCount？ And then what? FullChargeCapacity？ Two data, the former is the number of fully charged cycles of the iPhone battery, also called the number of charging cycles, and the latter represents the fully charged battery capacity. It can be seen that there is not much difference between the design capacity and the Wally capacity. The iPhone I bought in March 2065438+2002 should be said that the battery life is quite acceptable. Of course, iBackupBot has many other functions, such as? User information manager? You can view Safari's address book, information, memos, even bookmarks and browsing history (Figure 3). Multimedia file manager? You can view photos and videos. If it is a registered version, you can import and export data. Interested friends may wish to give it a try. This article comes from the system house.
