The story

By Thursday, Deniz had decided the watch was dying. It came off the charger at seven, and by four in the afternoon it was warning about low battery. A repair shop had quoted a battery swap, but Deniz did not want to pay for one if the real culprit was a setting turned on during the last update.

So on Thursday evening Deniz installed WristRevive and let it record a normal day. Friday morning the watch came off the charger and Deniz started a 24-hour Revive Scan, then simply wore it: the commute, meetings, a short run at lunch. The watch was not charged or restarted until Saturday morning, so the scan had clean data to work with.

The result marked two periods of unusually fast drain compared with the watch's own baseline. One was the run, which made sense. The other was a quiet hour in the evening when the watch was barely touched. That second one was the interesting part.

On Saturday, Deniz used the Idle Drain Test. One quiet hour as a baseline, then one change, then a matched quiet hour after it. The change was to a notification setting from the Everyday Lite checklist. The test showed the drain rates for both hours, the size of the difference and how confident the result was. The difference was small, and the confidence was low.

Deniz tried one more change the next evening, with the same outcome. Nothing moved the idle drain in a clear way. That did not prove the battery was worn, and WristRevive does not claim to certify battery health. But it made the battery the most likely explanation.

Before going back to the shop, Deniz opened the phone companion, looked over the charging periods and scan results on the bigger screen, and exported the diagnostics as a CSV. The repair conversation started with three days of data instead of a vague complaint, and Deniz reverted the Everyday Lite change using the restoration checklist.
