Best electric toothbrushes: six Oral-B and Sonicare models compared on sensors, modes and battery
An electric toothbrush is bought on a price tier and sold on a plaque percentage. What changes your brushing is plainer: a warning when you press too hard, how many days the battery lasts, a two-minute timer, and what the heads cost. Six brushes from the two makers that publish those figures, Oral-B and Philips Sonicare, from the cheapest round-head Oral-B to the DiamondClean with an app.

† Figure from a retailer listing or otherwise awaiting confirmation from the manufacturer; other figures come from manufacturer manuals and leaflets.
Battery days are each maker’s own figure. Oral-B’s pages contradict themselves on the iO2 and iO3, so those cells carry both numbers and are flagged. Philips publishes one figure per model. Mode counts for the Oral-B Pro 1 and iO2 are also disputed between Oral-B’s pages and the listings; the table shows what Oral-B’s specification says.
What actually changes your brushing
The plaque-removal percentages on the box compare each brush with a manual one under laboratory conditions, and every brush here clears that bar. What differs is whether the brush corrects you. A pressure sensor stops the most common mistake, scrubbing, which wears enamel and gums; the better ones also tell you when you are too timid. A two-minute timer with 30-second prompts fixes the second mistake, stopping early and skipping the back. A head-replacement reminder fixes the third: brushing with a splayed head for six months.
After that come comfort and cost. Battery days decide whether the brush lives on its charger or in a drawer. The heads decide what the brush costs over five years, and whether you can buy them in a supermarket.
Oral-B iO3, for most adults
for most adults: the sensor that says too soft as well as too hard
Oral-B iO3 (travel case + spare head)
- Modes
- 3 modes
- Pressure sensor
- 360° light: too hard, too soft or right
- Battery
- Up to 4 weeks (Oral-B); about 2 weeks in reviews†
- Timer
- 2-minute light ring, head-change reminder
- Brush heads
- iO round heads
Check price on Amazon
The cheapest Oral-B with the full pressure sensor: a ring of light that shows green when the pressure is right, red when it is too hard and white when you are too gentle, which no other brush under the DiamondClean does. Three modes (Daily Clean, Sensitive, Whitening), the iO light-ring timer, a reminder when the head is worn, a spare head and a travel case in this bundle, and a two-year warranty.
Oral-B’s battery claim of up to four weeks is not what reviewers measure, which is nearer two; the standard charger takes about 16 hours by user reports; and there is no indicator of which mode is selected.
For an adult who has been told to look after their gums, it is the one to buy.
Strengths
- Pressure feedback in both directions
- Spare head and case included
- Three modes with a whitening setting
Limitations
- Slow to charge on the standard puck
- Battery life claim is optimistic against reviews
- No display of which mode is selected
Good for
- most adults replacing an older oscillating brush
- gum-health advice from a dentist
Look elsewhere if
- someone who wants app coaching
Philips Sonicare 3100, for a sonic brush with a sensor
for a sonic brush with a pressure sensor at a low price
Philips Sonicare 3100 (HX4072/42)
- Intensities
- 3 intensities
- Pressure sensor
- Yes: handle vibrates
- Battery
- 14 days
- Timer
- SmarTimer 2 min, QuadPacer 30 s
- Brush heads
- Sonicare click-on (W Optimal White supplied)
Check price on Amazon
Philips’ cheapest brush with a pressure sensor: when you press too hard the handle vibrates in a different pattern. Three intensities, 31,000 movements a minute, the SmarTimer and QuadPacer that pace the two minutes in four quadrants, an EasyStart ramp for the first fortnight, and a 14-day lithium battery, all stated on Philips’ page. Two-year warranty.
The sensor is felt, not seen, which some people never notice, and the supplied head is Philips’ whitening type, which is firmer than its gum-care heads.
For someone who prefers the sonic buzz to the Oral-B polish, it is the sensible default.
Strengths
- Pressure sensor at a low price
- Three intensities
- Fourteen-day battery
Limitations
- Sensor is a vibration, not a light
- Supplied head is the whitening type, firmer than Philips' gum-care heads
Good for
- the sensible default for one adult
- someone told to ease off their gums
Look elsewhere if
- anyone who wants app tracking
Philips Sonicare 5300, for the longest battery

Philips Sonicare 5300 (HX7101/01)
- Intensities

- Pressure sensor
- Yes: handle vibrates
- Battery
- 21 days
- Timer
- SmartTimer 2 min, BrushPacer 20 s

Check price on Amazon
The newer Sonicare motor at 62,000 movements a minute, twice the 3100, with a 21-day battery, a pressure alert through the handle, the BrushPacer at 20-second intervals, and a reminder that tracks how hard and how often you brush and tells you when the head is done. Two intensities, no modes. Two-year warranty.
No app, and again the supplied head is the whitening type.
For anyone who travels, or shares a charger with a partner, three weeks per charge is the figure that matters.
Strengths
- Longest battery here: 21 days by Philips' figure
- Twice the movements of the 3100
- Tells you when the head is worn
Limitations
- No modes, just two intensities
- Supplied head is the whitening type
Good for
- someone who travels and forgets the charger
- a brusher who wears heads out unevenly
Look elsewhere if
- anyone who wants the Bluetooth coaching
Oral-B iO2, for the iO motor at the entry price
for the iO motor at the entry price
Oral-B iO2 (with travel case)
- Modes
- 3 modes†
- Pressure sensor
- Yes: slows the brush and lights red
- Battery
- Up to 4 weeks (page) / 10 days (specification)†
- Timer
- 2 minutes with 30-second pacer
- Brush heads
- iO round heads
Check price on Amazon
The entry iO: the round head with micro-vibrations, a sensor that slows the brush and glows red when you press too hard, the two-minute timer with a 30-second pacer, one button, and a travel case in this bundle. Oral-B’s pages give it three modes and up to four weeks of battery; Oral-B’s own specification table gives it two modes and ten days, so both facts are flagged.
Charging takes up to 16 hours, and it will not tell you when you are too gentle.
For a first electric brush with the Oral-B feel and a pressure warning, it is the cheapest route.
Strengths
- iO motor and pressure sensor at the entry price
- Travel case in the box
- One button, nothing to learn
Limitations
- Oral-B's mode and battery figures contradict each other
- Up to 16 hours to charge
- No app, no mode display
Good for
- a first electric brush
- someone switching from a manual brush who presses too hard
Look elsewhere if
- anyone who wants brushing data
Oral-B Pro 1, for the cheapest heads
for the cheapest heads over the years
Oral-B Pro 1
- Modes
- 1 mode†
- Pressure sensor
- Stops pulsations when pressing too hard; no light
- Timer
- 2 minutes with 30-second zone prompts
- Brush heads
- Pro heads (not iO)
Check price on Amazon
Oral-B’s basic oscillating brush, built for the older Pro heads, which cost less than iO heads and are sold everywhere. It has the two-minute timer with 30-second zone prompts and a gum-pressure control that stops the pulsations when you press too hard, which you feel rather than see. Oral-B’s comparison table gives it one mode; the listing says three.
Oral-B publishes no battery figure for it, and there is no light to warn you.
For a budget brush, a spare for travel, or anyone who wants the cheapest heads for the next five years, it is the one.
Strengths
- Pro heads cost less than iO heads
- Timer and zone prompts like the dearer models
- Light and simple
Limitations
- Pressure control gives no visual warning
- Battery life not published
- Mode count disputed between Oral-B's table and the listing
Good for
- a budget brush with a dentist's two-minute timer
- a second brush for travel
Look elsewhere if
- anyone who presses hard and needs to see it
Philips Sonicare DiamondClean 9000, for the app and the case
for someone who wants the app and the charging case
Philips Sonicare DiamondClean 9000 (HX9911/39)
- Modes
- 4 modes
- Pressure sensor
- Yes: light ring at the base
- Battery
- 14 days
- Timer
- SmarTimer 2 min, BrushPacer
- Brush heads
- Sonicare click-on (C3 Premium Plaque Control supplied)
Check price on Amazon
Four modes (Clean, Deep Clean+, Gum Health, White+) at three intensities each, a pressure sensor that lights a ring at the base, BrushSync heads the handle recognises and tracks, Bluetooth to the Sonicare app for coaching and reports, and a travel case that charges the brush over USB. 62,000 movements, 14-day battery, two-year warranty.
The battery is a week shorter than the cheaper 5300, the heads are the dearest Sonicare makes, and most people stop opening the app within a month.
For someone whose dentist has asked to see brushing data, or who travels for weeks with only a USB cable, it earns its price.
Strengths
- Twelve mode-and-intensity combinations and a gum-health mode
- USB charging travel case
- Head recognition and replacement reminder
Limitations
- Fourteen-day battery, a week less than the 5300
- Expensive heads and an app most people stop opening
Good for
- someone whose dentist has asked for brushing data
- frequent travel with the charging case
Look elsewhere if
- a budget or a first electric brush
How to choose
- Sensor. Two-way light: iO3. Red light: iO2. Light ring: DiamondClean 9000. Vibration: Sonicare 3100, 5300. Felt only: Pro 1.
- Battery. Sonicare 5300, 21 days. Every other Sonicare 14. Oral-B: read both figures.
- Heads. Pro heads cheapest, Sonicare click-on next, iO heads dearest.
- Timer. All six time two minutes; all but the Sonicare 3100 also remind you about the head, or at least pace you in 20-second steps on the 5300.
- Feel. Round and rotating: Oral-B. Oval and buzzing: Sonicare. Try a friend’s before committing to five years of heads.
Who should buy two cheap ones instead
A couple who each want their own handle and a drawer of shared heads do better with two Sonicare 3100s, or two Pro 1s, than one DiamondClean. Handles are personal; chargers and heads can be shared within a brand.
Which one, by situation
- Told to look after your gums: Oral-B iO3.
- Prefer sonic, want a sensor: Philips Sonicare 3100.
- Travel, forget chargers: Philips Sonicare 5300.
- First electric brush, Oral-B feel: Oral-B iO2.
- Lowest running cost: Oral-B Pro 1.
- Wants the data: Philips Sonicare DiamondClean 9000.

Oral-B or Sonicare?
Oral-B's round head oscillates and rotates and feels like a polish at the dentist; Sonicare's oval head vibrates at 31,000 or 62,000 movements a minute and feels like a buzz. Both clean well. Choose by the sensor and the battery you want, and by which heads you are happy buying for the next five years.
Do I need a pressure sensor?
If you have ever been told you brush too hard, yes, and you want one you can see or feel while brushing. The Oral-B iO2 and iO3 light up red; the iO3 also tells you when you are too gentle. The Sonicare 3100, 5300 and 9000 buzz the handle. The Pro 1 slows the brush without a signal.
How long should the battery last?
Philips states a figure for every model: 14 days for the 3100 and DiamondClean 9000, 21 days for the 5300. Oral-B's pages give 10 days to four weeks for the iO2 depending on which page you read, and nothing for the Pro 1. If you travel, the Sonicare 5300 is the safe choice.
What about the heads?
Heads are the real cost. Oral-B iO heads fit only iO brushes; the Pro 1 uses the cheaper Pro heads. All Sonicare click-on heads fit all four Sonicare brushes here. Every maker says change the head every three months; the Sonicare 5300 and 9000 track it and remind you.

Best bathroom scales: six body-composition scales from a no-app Salter to the eight-electrode Withings
Every scale here does the same trick: a small current through your feet estimates fat, muscle and water from how your body resists it. What differs is the maximum weight, the step size, whether it syncs by Bluetooth, Wi-Fi or not at all, how many people it remembers, and whether it measures your top half or guesses it. Six scales from Salter, Renpho, eufy and Withings.

How to choose an electric toothbrush: pressure sensors, modes, battery days and the cost of heads
Electric toothbrushes are sold on a plaque percentage and a mode count, and neither predicts whether you will brush better. This guide explains the pressure sensor and its three kinds, why a timer beats modes, how to read a battery claim, what heads cost over five years, and oscillating versus sonic, with four brushes as examples.
