How long does an electric shaver last?
Nobody publishes a lifespan. What they publish instead is a warranty term and a head-replacement interval, and between those two numbers is everything you can actually know before you buy.

The short version
No maker in this ledger publishes how long a shaver lasts. Two numbers stand in for it, and only three products state either. The warranty term is the closest thing to a manufacturer's own estimate - Braun publishes up to 5 years on the Series 8, Philips publishes 2 years extendable to 5 on registration for the 7800, and nothing else here states a term at all. The head interval tells you the running cost: Philips publishes 2 years for the 7800 - the longest in this ledger - Braun publishes 18 months for the Series 9 PRO+, Philips publishes four months for the OneBlade blade, and the rest publish nothing. What usually ends the shaver is neither: it is the sealed lithium cell, which is not user-replaceable on any of them.

Nobody publishes the number you want
There is no field on any specification sheet in this category that says how many years a shaver lasts, and there is no independent figure we can cite in its place. That is the honest starting point, and the rest of this page is about what you can use instead.
Three published figures bear on it, and each answers a different part of the question:
- The warranty term - the maker's own stated expectation, where one exists.
- The head replacement interval - how often the consumable has to be bought, which decides whether keeping the shaver alive is worth it.
- The battery - which is sealed, unpublished, and is what usually ends the product.
What each maker actually states
| Shaver | Warranty term | Head interval | Quick charge |
|---|---|---|---|
| Braun Series 8 8560cc | Up to 5 years | Not published | 5 min for one shave |
| Philips Norelco 7800 | 2 years, up to 5 on registration | 2 years (SH71) | 5 minutes |
| Braun Series 9 PRO+ | Not published | 18 months | 5 min for one shave |
| Philips OneBlade 360 | Not published | 4 months (blade) | Not published |
| Remington F5 | Not published | Not published | Not published |
Two things fall straight out of that table. The first is how empty it is: of five shavers, two publish a warranty term and three publish a head interval, and only one publishes both. The second is that the two disclosures do not travel together - Braun publishes a term on the Series 8 and an interval on the Series 9, and a buyer who wants both figures cannot get them from either box.
Why the warranty term is the best proxy available
A warranty is not a service-life specification. It is a commercial judgment about how many units will come back and what that will cost, and "up to 5 years" is conditional language tied to registration - Braun's conditions are the ones that govern, not our summary of them.
It is still the only number in this category where a manufacturer commits to anything about duration. On a sealed appliance with a non-replaceable cell, a company stating that it will stand behind the product for five years is a meaningful signal in a field where the alternative signal is silence.
The battery is what actually ends it
Every shaver here is a sealed unit. The waterproof rating that lets you rinse one under a tap and use it in the shower is the same construction that puts the cell permanently out of reach, and none of these makers publishes a cell chemistry, a rated cycle count, or a replacement procedure.
That is the practical end of the product. A motor in a shaver is a small, lightly loaded thing; a foil or a cutter is a consumable you can buy; a lithium cell loses capacity with every cycle and cannot be swapped. When the shaver starts giving you one shave where it used to give you a week, that is the end, and no amount of new heads changes it.
What you can do about it before buying is choose a shaver with a quick charge, which all three flagships here publish at five minutes for one shave. A tool that can be topped up in five minutes never has to be run to empty, which is the only part of cell management the published specifications put in your hands. The battery life page covers what the runtime figures do and do not tell you.
The heads are the running cost, not the lifespan
These two questions get mixed together constantly and they are separate. The heads wear out on a schedule and are replaceable; the shaver does not and is not.
What is published is thin and inconsistent. Philips states 2 years for the 7800's SH71 heads, which is the longest published interval in this ledger. Braun states 18 months for the Series 9 PRO+ cassette. Philips states four months for the OneBlade blade, which is a different kind of part on a different kind of tool. Everything else is blank, which means the main ongoing cost of owning those shavers arrives on no schedule at all.
That absence is worse than it sounds, because a foil degrades gradually: the shave gets slower, then it starts tugging, and most people do not notice until it has got significantly worse. A published interval prevents that. When there is not one, the foil life page lists the symptoms to watch for instead, and the replacement guide covers the job itself.
What to actually do with this
- Buying for yourself, keeping it for years. Weigh the published head interval first - it is the recurring cost and the Philips 7800's two-year figure is the longest stated here. Then put the figure into the calculator with the price of a cassette.
- Buying as a gift. Weigh the published warranty term first. It is the only verifiable statement that the thing will still work in a few years, and only the Braun Series 8 and the Philips 7800 make one - the head-to-head puts them directly against each other.
- Replacing a shaver that has started dying mid-shave. That is the cell, not the heads. Do not spend money on a cassette for it.
- Wanting a tool with no battery at all. Nothing in this ledger qualifies, and that is a real gap in the category rather than an oversight in our coverage.
Every pick, with the working
Each entry shows the published specifications, the axis scores they produce and what you give up. The order is the computed order, not a commercial one, and the arithmetic is open underneath every score.
Our pickThe whole box, not just the shaver
Braun Series 8 8560cc
The reason to pick this over a Series 7 has little to do with the shave: Braun publishes the box contents, and they are the shaver, a 5-in-1 SmartCare Center, a cleaning cartridge, a travel case, a brush and a cord. Four sonic-powered shaving elements on a 40-degree swiveling head, 60 minutes of published runtime, a five-minute charge for one shave, 100% waterproof, and a published warranty of up to five years - the longest term any shaver in this ledger puts in writing.

- Warranty
- Up to 5 years
- Assumed service life
- 1,300 uses
The arithmetic: 260 uses a year x 5 years of assumed service life = 1300 uses.
What it gets right
- Braun publishes the box contents in full: shaver, 5-in-1 SmartCare Center, cleaning cartridge, travel case, brush and cord
- Published warranty of up to 5 years, the longest stated term in this ledger
- 4 sonic-powered shaving elements and a published 40-degree swiveling head
- 60 published minutes with a 5-minute quick charge for a single shave
- 100% waterproof, so it works in the shower and rinses under a tap
Flaws
- The SmartCare Center is a second proprietary consumable - cartridges, bought forever
- Braun publishes no shaver-head replacement interval, so the main running cost has no stated schedule
- No charge time published, only the quick-charge claim
- A station is a counter appliance; the travel case is the part that actually travels
The working behind the 6.9
- How long it lasts: not scored
- Not scored. This is a durable item, not a consumable, so how long it lasts is an assumption about service life rather than something the pack size tells us.
- Ease of switching: 9.0
- Everything needed to own it is in the published box contents, so there is no second order (++), a 5-year stated warranty term (+), 60 minutes and a 5-minute quick charge (+), but the station is a second proprietary consumable (-) and Braun publishes no head replacement interval (-).
- Refill economics: 4.0
- Only this maker's refill fits, so the ongoing price is set by the maker rather than by a market. This is where the real cost of ownership hides.
- What the maker publishes: 6.0
- 3 of 5 specifications a buyer would expect are published: runtimeMin, cuttingElements, waterproof. Not published: chargeMin, headReplacementMonths. 3 / 5 x 10 = 6.0.
Axes with no published input are dropped and the remaining weights re-normalized, so a product is not punished for a category where an axis does not apply.

2Rotary heads and the longest published head interval
Philips Norelco 7800
Forty-five SteelPrecision blades across heads Philips publishes as flexing through 360 degrees, sixty minutes of runtime, a five-minute quick charge and a published two-year head replacement interval - the longest published interval in this ledger. Fully washable, and Philips publishes that it can be used in the shower.
- Runtime
- 60 min
- Charge time
- 60 min
- Head replacement
- Every 24 months
- Waterproof
- Yes
- Made in

- Refill
- Proprietary to the maker
- Warranty
- 2 years (up to 5 on registration)
- Assumed service life
- 1,300 uses
The arithmetic: 260 uses a year x 5 years of assumed service life = 1300 uses.
What it gets right
- Published 360-degree flexing heads - the rotary answer to a contoured face
- Published 60-minute runtime with a published 5-minute quick charge
- Published head replacement every 2 years with SH71 - the longest published interval here
- Fully washable, wet and dry, and published as usable in the shower
- 2-year warranty published, extendable to 5 years on registration
Flaws
- The power adapter is not included, which Philips publishes
- Philips publishes the blade count but not the number of cutting heads
- No corded-operation statement published
- Rotary shavers suit a few days of growth better than a daily bare shave
The working behind the 6.9
- How long it lasts: not scored
- Not scored. This is a durable item, not a consumable, so how long it lasts is an assumption about service life rather than something the pack size tells us.
- Ease of switching: 8.0
- Published runtime, quick charge and a 2-year head interval (++), washable and shower-safe (+), but proprietary heads (-) and no adapter in the box (-).
- Refill economics: 4.0
- Only this maker's refill fits, so the ongoing price is set by the maker rather than by a market. This is where the real cost of ownership hides.

3The closest electric shave
Braun Series 9 PRO+
Five synchronized shaving elements — two gliding foils, a SkinGuard, a Direct & Cut blade and a Lift & Cut blade — plus a titanium-coated ProLift blade, 60 minutes of runtime, a five-minute charge for one shave, and it is fully waterproof. If the requirement is 'as close as an electric gets', this is the answer and there is not much argument about it.

- Warranty
- Not published
- Assumed service life
- 1,300 uses
The arithmetic: 260 uses a year x 5 years of assumed service life = 1300 uses.
What it gets right
- Five published cutting elements, each with a stated job, plus the ProLift blade
- 60-minute Li-Ion runtime, the longest of the shavers here
- 5-minute quick charge for a full shave
- 100% waterproof; usable wet with lather
Flaws
- Replacement head cassettes are proprietary and are the real long-run cost
- Braun's published 18-month replacement interval is guidance on its parts pages rather than a figure on the product specification, so it is easy to miss before you buy
- The most expensive way to remove hair in this ledger
The working behind the 7.4
- How long it lasts: not scored
- Not scored. This is a durable item, not a consumable, so how long it lasts is an assumption about service life rather than something the pack size tells us.
- Ease of switching: 9.0
- Wet-and-dry with 60 minutes of runtime and a 5-minute quick charge; nothing about daily use requires a decision (++). Braun publishes an 18-month foil-and-cutter replacement interval, which at least makes the running cost plannable (+), but the cassettes are proprietary so the price of it is Braun's to set (-).
- Refill economics: 4.0
- Only this maker's refill fits, so the ongoing price is set by the maker rather than by a market. This is where the real cost of ownership hides.
- What the maker publishes: 8.0
- 4 of 5 specifications a buyer would expect are published: runtimeMin, cuttingElements, waterproof, headReplacementMonths. Not published: chargeMin. 4 / 5 x 10 = 8.0.

4Trimming, edging and shaving with one blade
Philips Norelco OneBlade 360
Not a shaver and not a trimmer: a single oscillating blade that trims with a comb, edges without one and takes stubble down close without ever going properly bare. 45 minutes of runtime, five comb lengths from 0.2 to 5 mm, waterproof, and Philips publishes a four-month blade life with an indicator that tells you when it is up.

- Proprietary to the maker
- Warranty
- Not published
- Assumed service life
- 1,300 uses
The arithmetic: 260 uses a year x 5 years of assumed service life = 1300 uses.
What it gets right
- Published four-month blade life with a wear indicator on the blade itself
- Five comb settings from 0.2 mm to 5 mm plus bare-blade edging
- 45-minute runtime, 100% waterproof, usable in the shower
- The cheapest entry point to a powered shave here by a wide margin
Flaws
- It will not give you a properly bare shave; that is a design decision, not a fault
- Proprietary blades, replaced on a schedule, which is the real cost of ownership
- 45 minutes of runtime
The working behind the 7.1
- How long it lasts: not scored
- Not scored. This is a durable item, not a consumable, so how long it lasts is an assumption about service life rather than something the pack size tells us.
- Ease of switching: 9.5
- Published 4-month blade life with an indicator, so the one maintenance decision is made for you (++), waterproof and shower-usable (+), five published comb lengths (+), proprietary blades on a schedule (-).
- Refill economics: 4.0
- Only this maker's refill fits, so the ongoing price is set by the maker rather than by a market. This is where the real cost of ownership hides.

5The cheapest foil that is not a false economy
Remington F5 Power Series
Two flexing foils, an interceptor trimmer between them, a pop-up detail trimmer and 60 minutes of cordless runtime from a two-hour charge. It is a fraction of the Braun's outlay and it does not pretend to match it — but for an occasional or travel shaver it is enough tool.

What it gets right
- Published 60 minutes of cordless runtime
- Twin flexing foils with an intercepting trimmer for longer hairs
- Pop-up detail trimmer included
- Costs a fraction of the premium foils here
Flaws
- Two-hour charge time, the slowest here
- Not designed for wet use with lather in the way the Braun and Panasonic units are
- Replacement foils and cutters are proprietary and worth checking the price of before you buy
The working behind the 6.2
- How long it lasts: not scored
- Not scored. This is a durable item, not a consumable, so how long it lasts is an assumption about service life rather than something the pack size tells us.
- Ease of switching: 7.5
- 60 minutes of published runtime (+), pop-up trimmer (+), but a 2-hour charge and no published waterproof rating make it a worse daily tool than anything above it (--).
- Refill economics: 4.0
- Only this maker's refill fits, so the ongoing price is set by the maker rather than by a market. This is where the real cost of ownership hides.

Questions people actually ask
So how many years should I expect?
We will not give you a number, because none is published and this site does not invent figures. What you can act on is this: the only manufacturer statements about service life in this ledger are warranty terms, the longest of them is Braun's up to 5 years on the Series 8, and a sealed lithium cell is the component that determines whether a shaver reaches that point.
Is the warranty really a proxy for lifespan?
It is the only one available, and it is imperfect. A warranty is a commercial decision as much as an engineering one, and "up to" is doing real work in Braun's phrase - the term is tied to registration, so read the maker's own conditions rather than ours. But a stated maximum term is still a company putting a number on how long it expects the thing to keep working, which is more than a blank field does.
Can I replace the battery?
Not on any shaver in this ledger. These are sealed, waterproof-rated appliances, and the same construction that lets you rinse one under a tap is what makes the cell inaccessible. No maker here publishes a cell chemistry, a cycle count or a replacement procedure. Treat the battery as the end of the product.
What is the difference between the shaver lasting and the heads lasting?
The heads are the consumable, and they are a separate purchase on a separate schedule - the foil life page covers that in full, including the symptoms that tell you to replace them when nobody has given you a date. This page is about the machine: the motor, the body and the cell, which are not replaceable and which decide whether buying new heads is still worth doing.
Does running it flat every time shorten its life?
We have no published figure from any maker in this ledger on charging behavior and cell longevity, so we are not going to assert one. What is published is that all five of these shavers quick-charge - Braun publishes five minutes for a single shave on both the Series 8 and the Series 9 PRO+, Philips publishes five minutes on the 7800 - which means never having to run one to empty is a designed-in option rather than a discipline.
Is a more expensive shaver more durable?
Not on any published evidence we can find. Price buys cutting elements and disclosure rather than years - the price page works through what the money actually goes on. The one genuine correlation is that the dearer models are the ones more likely to publish a warranty term at all.
What about a corded shaver - does that last longer?
It removes the failure mode entirely, which is the honest case for one. Nothing in this ledger is corded-only, so we cannot point you at a product; what we can say is that in the adjacent clipper category, the argument for mains power is precisely this - the corded versus cordless page makes it.
Does this change what I should buy as a gift?
It should. A published warranty term is the only verifiable statement about how long a present will keep working, which is why the gift-set roundup ranks on disclosure rather than on shaving ability, and why the gifts-for-dad page picks the Series 8 over the flagship.
