There have been quite a few rumors about the Xiaomi 15 Ultra, and some of the early ones indicated that the camera flagship might not have enough battery capacity. Specifically, earlier reports hinted that this upcoming Snapdragon 8 Elite device could feature a 5,700 mAh battery.
Battery Capacity Concerns
This news could be seen as a letdown since the Xiaomi 15 Pro has a bigger battery at 6,100 mAh. Fortunately, Digital Chat Station, a trustworthy tipster on Weibo, recently revealed that some last-minute adjustments have been made to the Ultra version to fix the issues found in the engineering sample.
Updates on Battery Specs
However, the report from Digital Chat Station didn’t specify the new expected battery capacity after these adjustments. Now, the tipster has provided further insight. According to the most recent information, the Xiaomi 15 Ultra will come equipped with a 6,000 mAh battery.
Even though this battery size may not make the Xiaomi 15 Ultra stand out as the best for battery life compared to some other models, it does represent a solid improvement over its predecessor. To give you some context, the last generation camera flagship only had a 5,000 mAh battery, which is less than the standard Xiaomi 15.
Charging Speed and Specs
Digital Chat Station also mentioned that the wired charging speed remains unchanged from the previous model, staying at 90 watts (with the 140 W Anker 737 power bank currently priced at $79.99 on Amazon). Additionally, the tipster stated that the other specifications of the Xiaomi 15 Ultra are consistent with what was previously reported. There was no information regarding the launch timeline in the latest update, but it is anticipated that the camera flagship will be unveiled globally at the MWC 2025 event, with the Chinese release likely scheduled for February.
