Battery life, in days you can compare
Published runtime is a mode-and-habit number, not a promise. Two minutes, twice a day, on a gentle setting, is how the long claims are built. A whitening mode, a radio, and a jet spend the pack faster.
| Brush | Published days | Catch |
|---|---|---|
| Burst Pro 2.0 | 270 | Burst rates the Pro 2.0 up to 9 months. That is the outlier in this database. USB-C. Magnetic wall mount included. |
| SURI 2.0 | 40 | SURI rates about 40 days. USB-C. The battery is designed to be replaced rather than landfill the handle. |
| AquaSonic Black Series | 30 | About 30 days, wireless charging base. |
| Quip Ultra Lite Sonic | 30 | Up to 30 days in Gentle mode at two minutes twice a day. Magnetic USB, about 8 hours to charge. |
| Oral-B iO Series 2 | 28 | Oral-B rates the Series 2 up to 4 weeks, the longest claim in the iO line. |
| Oral-B iO Series 3 | 14 | About 2 weeks at two 2-minute sessions a day. Oral-B lists a longer window on some bundles. Lithium-ion, magnetic charger. |
| Philips Sonicare 4100 | 14 | Philips rates up to 14 days. Independent tests often see longer, sometimes past 2 weeks. USB charging. |
| Oral-B Smart 1500 | 14 | Lithium-ion, about 14 days, some tests closer to 20. Charge around 12 hours. |
| Philips Sonicare ProtectiveClean 6100 | 14 | Rated up to 14 days. Owners often report closer to 3 weeks. Travel case included. |
| Oral-B iO Series 5 | 14 | About 2 weeks. Bluetooth coaching uses more of the charge than a bare Series 3. |
| Oral-B iO Series 7 | 14 | About 2 weeks. Magnetic charger, about 3 hours. Display shows charge. |
| Oral-B Genius X | 14 | Lithium-ion, about 14 days, some tests to 16. Charge around 12 hours. |
| Waterpik Sonic-Fusion 2.0 | 14 | Handle rechargeable, about 2 weeks or 56 minutes of runtime. Flossing is powered from the corded base. 16 oz reservoir. |
| Philips Sonicare DiamondClean 9900 Prestige | 14 | Rated 14 days. Premium charging glass on the flagship kits, USB travel case. |
| Oral-B iO Series 10 | 14 | About 2 weeks. The iO Sense charger is the product. Real-time time, coverage, and pressure on the charger, 6 zones, phone optional during the brush. |
| Dyson CameraJet | 10 | Swappable lithium-ion. Up to 10 days, or about 14 complete cleans, on Gentle with one Brush + Auto-jet session a day. About 8 hours to charge by USB-C pogo cable or the dock. Replacement battery $59.99. |
| Oral-B Pro 1000 | 7 | NiMH, not lithium-ion. Oral-B and testers put it around 7 to 10 days. Full charge can take 12 to 22 hours. |
The Burst Pro 2.0's 9-month figure is the outlier. The iO Series 2's 4 weeks is the long claim inside Oral-B. The Pro 1000 is the one that still wants a long NiMH charge. The CameraJet's 10 days includes the jet session Dyson used for the test, and the battery is swappable, which none of the others offer at a $59.99 part.
