In the news of 24 june, today's official question-and-answer session on the mi service was launched to read in detail the battery upgrade extension service for the mi13 series, which is a clear difference between the official service and the common equivalent battery replacement。
The normal replacement only restores the original plant and the battery upgrade replaces the high-energy-density high-capacity custom core, increasing the continuation in the same body structure。
In addition, if required to secure ip68, users can choose a door shop with an ip68 service logo that can still be maintained to support water protection, and there are now 600+ service centres across the country to support ip68 service delivery。

Battery services may be purchased and booked by:
Mode i: the micro-intelligence search for millet service applets select the battery service of the appropriate model, immediately purchase the selected service mode, shop time and booking。
Mode ii: app search and selection of battery services of the same type in the town of millet, immediately purchase the selected service, the time of arrival and the appointment of a store. Mode three: the mi ap navigation column [commercial city] searches and selects the battery service of the appropriate model to immediately purchase the selected service, the time of arrival and the appointment of the store。

The mi13 system has now launched its counterpart service, and additional support for the mi14 and mi14 pro types is expected in the fourth quarter of this year。
Upgraded batteries are increased by about 7 - 11 per cent compared to the original capacity of new batteries, which means that, under the same usage habits, one or two additional hours per day can be used。
The upgraded capacity of the mi13 series is as follows:
Mi13:4500 mah→4850 mah with approximately 7. 8% capacity increase
Mi13 pro: 4820 mah ~ 5361 mah with capacity increase of approximately 11%
Mi13 ultra: 5000mah ~5500mah with capacity increase of about 10%
