How to determine whether the needs of your iPhone or iPad to replace the battery

As with any mobile device, for iPhone and iPad is very important autonomy. Every year the requests from users are growing, expanding the usage scenarios and the possibility of batteries in mobile gadgets are at the same level due to the ever decreasing thickness and weight.

Complaints about the lack of battery life can be heard from many users, but also to understand whether your unit battery needs to be replaced or you're just too actively use it? On this and will be discussed further.

Discharged or not

It sounds corny, but you first need to see if the device itself is discharged or discharge a you. To do this, just enough time to refrain from active use and observe the charge level. It is best to fully charge the unit and leave for the night, after making a screenshot of the charge level at the current time. Do not forget to turn off notifications, to eliminate the possibility of discharge due to a variety pushey.

In the morning, check the charge level. If it is not changed or dropped by a couple of per cent - then everything is normal with the battery and the rapid discharge is caused by the active use. If the charge has fallen by more than 10% - something still it discharges. In this case, proceed to the next step.

We determine the cause of the discharge

We need to determine where it goes the charge: "eat off" if its background processes and services, or the discharge is caused by a decrease in battery capacity due to wear. It's pretty simple to do via the built-in battery usage statistics. Starting with iOS 7.0, we have not only the use of meager numbers and expectations (though enough of them), and even detailed statistics on applications.

The bottom line is that the iPhone and iPad standby mode should not be discharged, so the waiting time from the menu Statistics should be considerably longer than the time of use (while the device is in a state rest).

If you have a waiting time is equal to or nearly equal to the time of use - it means there is a background activity of applications or services, which is the reason for the discharge. It is worth checking the application from the list and their access to upgrade content, geolocation, and other things. And here's another some useful tips for you.

If everything is in order, and the battery still holds very little even with sparing use - go to the next step.

Testing the battery

Almost certainly the problem is the deterioration of the battery, which is inevitable after prolonged use. In the process of charge-discharge capacity of the battery decreases. On the iPhone it drops to 80% after 500 recharging cycles, iPad stands twice - in 1000. Learn how to reduce the maximum capacity of the battery on your machine. If you fall too much and actual autonomy does not suit you, it is time to change the battery.

If your device is updated to iOS 11.3, you can see how it diminished the capacity of the battery for operation at all times, without any additional software. To do this, go to "Settings» → «Battery» → «Battery status." The apparatus will show the current value of the maximum capacity in percentage of the original.

If your device has an older version of iOS, you can learn the status of the battery using Battery Life Doctor free application. Run it and click Details next to the item Battery Raw Data - see option Design Capacity in the next menu (initial maximum capacity). Next to it will be displayed the current maximum capacity of the battery as a percentage of the original.

Another way to find the battery - the program iBackupbot for macOS and Windows.

Download programs link, Open, connect the device to your computer and click More Information. We are interested in indicators DesignCapacity (initial maximum capacity) and FullChargeCapacity (the current maximum capacity). It remains to calculate the difference yourself. If it is too high, consider replacing the battery.

What to do next

75-80% of the plant capacity is still not fatally, and with this you can safely move on, but if your script to use this autonomy is not suitable, then you have to replace the battery.

Do it better in the official or credible services. If you decide to carry out the replacement yourself, then do not buy a suspiciously cheap batteries and keep in mind that unlike the iPhone 4 / 4s in later devaysakh (and all iPad) replacement procedure involves the complete disassembly of the device, which requires the respective skills.

And further. Before you go to the service center, Try to calibrate the battery. Many people help, but the attempt - not torture.
