An electric shaver is a gadget that most men and women-owned these days.

They aren’t too expensive, but if some are expensive, they always pay their prices back in the long run.

Although inexpensive options are available such as disposable razors and safety razors, believe me, they aren’t as comfortable as electric shavers are.

There are some inexpensive electric shavers also available. You can go for it instead of a disposable razor, but expensive ones also pay their prices back.


Let me explain.

How long does an electric shaver last? 

An electric shaver lasts for 5 to 7 years, but it also depends on how you care and what brand you have. If you have some high-end shavers such as Braun series 7 or Panasonic Arc5 they can last for 10 to 12 years. But, you need to change blades. It is recommended by most brands that Blades of electric shavers should change somewhere between 12 to 18 months, but if you use them carefully then the blades of high-quality shavers can last even longer. 

Although, you need to take care and clean the electric shaver properly after every shave. But, this will give an idea about the worth of electric shavers and how electric shavers pay their prices in the long run.

In this article, we will discuss in detail, the lifespan of electric shavers, electric shaver blades, and batteries.

A typical Electric shaver can last for 3 to 5 years. It also depends on the brand you purchase. A high-end electric shaver can last for 7 to 10 years or more. Although it needs continuous maintenance otherwise it can last for only a few months. However, some high-quality electric shavers such as Braun series 7 or Panasonic Arc5 come with a 2 to 3 years warranty.

The lifespan of a high-end Electric shaver can be very long for 7 to 10 or more, but you can’t expect that with an entry-level Electric shaver.

An entry-level electric shaver is under $30, and if they serve you for 2 to 3 years or even for 1 year, that’s enough. Although a woman doesn’t need a very high-quality Electric shaver, an Electric shaver between $50 to $60 is enough and it would last long enough.

I know you want an electric shaver that lasts forever or if not forever then at least more than 7 years. 

It is totally your choice what electric shaver you want and no one can tell you what is the right shaver but you. But in my opinion for men, an electric shaver between $100 to $150 is enough and its lifespan would be 3 to 5 years which is more than enough. After that, you can have a new and more advanced technology that is changing at a very fast rate. So, I don’t think you should always stick to one shaver. But, if your old shaver works very smoothly then you can stick with it.

Depending on your hair type, shaving frequency, and brand you purchase, the blades of a typical electric shaver can last for 12 to 18 months. If you are lucky and purchased a high-quality shaver can get past the 18 months. 

But it is recommended by most brands that foil and blades of electric shaver should be changed between 12 to 18 months.

The lifespan of foil and blades depend on a few factors such as how coarse and dense your hair, how often you shave, the quality of the electric shaver, how well you take care of the electric shaver aftershave, how you shave dry or wet? These factors affect the life of an electric shaver. 

You may need to buy new foil and blades sooner if the factors are against you.

And If you minimize the damage to your electric shaver at every level, chances are the blades can last for longer than expected and can even pass the 2 years mark but more than 2 years or even 2 years is highly unlikely.

Sharp blades eventually dull after continuous use and they start to irritate your skin. That is why it is necessary to change the blade after some time. It is recommended that blades should change 12 to 18 months or sooner.

Blades are made with sharp edges. Continuous use of sharp edges eventually makes them dull. Electric shaver blades can’t sharpen easily. So, due to physical limitations, the only option is to replace them.

Apart from dullness, shaver blades are made to provide extreme closeness which gives it high precision and low tolerance.

Blades continuously oscillate and sometimes touch the foil when pressurized against the skin.

This friction produces heat and causes deform.

Sometimes they heated the foil too much that you can see holes in foil which can cause injuries to your skin.

So, if closeness suffers, the shaver gets too hot, and foil starts to wear change blades and foil immediately.

For better, smooth, and close shave changing blades is very important.

There are few signs which tell you that now it is time to change the blades and foil.

1. Shaver start pulling and tugging

This is the first sign you will experience when shavers start to yank hair; it is due to the dullness of blades and foil. This means blades are not sharp enough to cut hair properly. It doesn’t matter if this is just the sixth month after the buy or the third year. If the shaver pulls hair, change the cassette.

2. You need to shave the same place again and again

When a shaver leaves hair behind then you need to go to the same place again and again. And you need to press the shaver hard against the skin. It is also a sign that blades need to change. It is also due to the dullness of the blades. If you are experiencing this, regardless of the time, change the blades immediately.

3. Foil getting hot very quickly

If the foil head gets hot quickly this means there is too much friction between blades and foil. The friction between foil and blades is due to the deformed shape of metal. And deformed shape means changing blades immediately. 

In short, if the foil is getting hotter than usual and very quickly and it is hard to stick a shaver against skin change blades immediately.

4. if there is any wear and tear on foil

If there is any wear on foil to change the blades immediately it can cause injury and infection. Wear blades are more dangerous than dull blades. You can have one or two shaves with dull blades but with wear blades not even one

How long does the battery of the electric shaver last?

Most electric shaver batteries should last 5 to 7 years because they are made of Li-ion.

If you have a high-end shaver it has a battery lifespan of 7 to 10 years or even longer.

Most electric shavers are made of lithium-ion batteries. 

The typical life of a Lithium-ion battery is about 300 to 500. One cycle is fully charged to fully discharge. You can have almost 5 shaves with 1 cycle. If you calculate this in shaves it would take 5 to 8 years before the battery reduces its performance noticeably.

Although, there are continuing changes in technology and brands are making better and better batteries. 

So, if you have a high-quality shaver its battery can last up to 15 years.

Although, not all electric shaver’s batteries are made of Lithium-ion. Some batteries are made of Ni-Cd and NiMH.

Ni-Cd batteries have the highest lifespan of more than 15 but they store less energy per unit and take a longer time to charge. That is why most of the brands are using Lithium-ion batteries, not Ni-Cd.

How to increase the lifespan of electric shavers and foil and blades of Electric shavers?

There are few ways that can help you to increase the lifespan of the blades of an electric shaver. It will increase the lifespan by at least 50% after that eventually you will need to change blades, but a 50% increase is quite significant.

clean you shaver

1. Clean your shaver thoroughly after every shave

It is also important to clean the shaver according to the guideline of the manufacturer although today most shavers can be cleaned with hot water or soap.

Some shavers include cleaning stations such as Braun series 9, Panasonic Arc5, etc. You need not worry about them.

2. Deep cleaning shaver

Sometimes you need to deep clean your shaver because during shaving some hair can go inside and won’t come outside with liquid.

To clean these hairs you should open the head of the shaver and then clean the blades properly.

It is not complicated, you just need to do some extra work and need to disassemble the shaver head.

3. Lubricate blades

Although you should lubricate blades only if advised by the manufacturer, it is not necessary.

Lubrication decreases the friction between foil and blades which prevents extra heating.

4. Store shaver in a dry place

Do not hurry, in case of storing. Most people wash the shaver properly and then immediately store it in its case. It is not a good practice because moisture causes rusting which erodes the blades and foil. Believe me, it is the fastest way to ruin your shaver blades.

After cleaning the blades let it dry properly and then store it in its case, chances are your shaver will serve you longer than expected.


An electric shaver can last for 10 to 15 years, but you would need to change blades continuously after every 12 – 18 months.
