Memory variants

Each row compares the same storage capacity. Cells show recorded RAM alternatives, not combined maxima. Not recorded does not mean unavailable in every market.

No unambiguous storage/RAM pairings are recorded. See the original specifications below.

Practical features

Explicit Yes and No values are shown directly. Qualified or regional records retain their details. Unknown means the record is missing.

Battery capacity

Capacity is not battery life. No endurance test is implied.
