If you are an owner of an iPhone XR, XS and XS Max and thinking to replace your iPhone battery yourself or from your neighborhood repair store, think again! As per guys at iFixit, if you replace the batteries in the above phones from other than Apple authorised service centres, your battery will still be in Service mode. This is indicated in the Battery Health of the Battery settings. A ‘Service’ status of the Battery Health means that your iPhone’s battery is degraded and needs to be replaced. Even though you replace your battery with a genuine Apple battery, you will still get this status. You will also be greeted with an “Important Battery Message” displaying “unable to verify this iPhone has a genuine Apple battery”.
Generally, a microcontroller is used on batteries that communicate with the phone to display its status, health and more. However, in iPhone’s case, the microcontroller also includes an authentication feature that passes the battery information to the logic board. Hence, when this unique authentication key is not passed to iPhone’s logic board, the battery health will be in Service. This means, although you would have swapped a battery from another iPhone or replaced with a genuine Apple battery but had it installed locally, your iPhone will not recognise it. Only Apple has the software that can enable the genuineness of the battery. On a good note, the performance of the phone will not be affected nor it would be throttled by Apple.
However, in best of interest of the phone, we would also recommend getting your iPhone battery replaced at their authorised service centres.
