Phone Storage Growth Forecast

MEASURED TREND

Project retained local storage

Measure the device at least twice. Count files you keep, not temporary downloads you routinely remove.

Current used storageCopy the used-storage value from the phone's settings.Observed ownershipLonger observation windows reduce the effect of one unusual trip or download.Monthly retained growthSubtract the earlier used-storage reading from today's reading, then divide by elapsed months.Remaining ownershipUse the number of months you expect to keep the replacement phone.Safety reserveReserve room for system updates, app updates, travel, and short-term camera bursts.

Measure local storage, not cloud quota

Cloud backup and local capacity solve different problems. Apps, offline files, messages, projects, and optimized photo copies still occupy the device. Repeat the measurement after a representative month and exclude one-time downloads you know you will remove.
