Questions about this item

Will the 5000mAh battery need replacement and how often?

The 5000mAh battery is sealed inside the chassis. Normal capacity loss after a few hundred charge cycles may eventually require professional service.

Which component hits its limit first during hours of 8K video recording?

The Snapdragon 888 processor and 108MP sensor generate sustained heat; thermal throttling typically activates before storage or memory fill.

How loud or hot does the phone get when the 120Hz display runs all day?

The adaptive 10Hz–120Hz panel and large vapor chamber keep surface temperature warm but not uncomfortable; fanless design means zero audible noise.
