If you’re looking at buying a new phone you’ve undoubtedly, at some point, come across the debate between removable and non-removable battery types. For most people, it will be an inane question rather low on the list of specifications, but for a number of consumers it can be a huge sticking pint.

Phone buyers have had a love-hate relationship with their mobile batteries. From the bricks that would last days to the sleek one-day-use units we see in modern phones, removable and non-removable battery packs have also split or annoyed users for decades.

A huge proportion of modern smartphones and tablets now come with non-removable batteries, compared to the removable battery formats of their ancestors.

So what are the advantages of the two types of battery design and why do manufactures constantly chop and change their format?

Removable Battery

Removable batteries are batteries that are designed to be taken out of the host device.


  • Hard restart. The old adage “Have you tried turning it on and off again” is often the fix for many of the world’s tech problems. Although whipping your battery out at the first sign of trouble if not often the best idea (it can be damaging in some circumstances) this ‘hard restart’ method is proven to work when all else is frozen and the manual restart won’t work.
  • Easy to dry. If you do happen to get a little too much water on a phone, removable batteries have a slight advantage over their sealed counterparts as you can try and get said battery out before it has time to short. You can then dry the separate component and pray to the god of tech for compassion.
  • Replaceable. Unfortunately, batteries don’t last forever, and frankly modern batteries don’t last that long at all so buying a replace is a good fix for when your old power source is just not holding its charge.


  • Untraceable– this might be an advantage for some, but for most people, if your phone is stolen and the battery is removed, it’s effectively untraceable (digitally).
  • Damageremoving a battery usually requires the phone to be literally cracked open, meaning the internal working of the phone have a higher chance of damage or contact with dust and dirt
  • Size Phones with removable batteries tend to have a slightly larger frame size as the battery is not sealed or manufactured into the closed case.


Non-Removable Battery

Ok so that’s removable, so guess what no removable is…? Yep as the name suggests, non-removable batteries are not designed to be taken out of the phone/tablet by the consumer.  In fact many non-removable batteries are literally built into the device, meaning the battery pack cannot be separated from the device.

Just a note here, it is sometimes physically possible to remove a number of the non-removable batteries, however there is a substantial risk the device will be damaged if you do, as well as a risk to the user if you puncture the battery whist trying to remove it. A few non-removable batteries are simply glued or clipped in, but tampering with the battery will likely result in a voided warranty. Once again, it’s possible, but just don’t bother.

Ok back to the battery;


  • Less parts that can break– Very difficult to get inside the phone and tamper with delicate parts, that could cause damage.
  • Less gapsLiterally less room for dust or dirt to access the device, and no chance for dirt to be transported in through changing a battery
  • Slimmer battery– Phone manufacturers can make their phone slimmer as the battery unit is designed and seal together.
  • Single frames or ‘unibody design’ are usually more solid than phones with battery ‘doors’ and often look far sleeker.


  • Battery issues are terminal. This is the big disadvantage of sealed units, if your battery malfunctions or begins to fail, you’re stuck with it, as it cannot be (easily) replaced. In most cases you’ll need to replace the whole phone for a simple battery fault.
  • No Battery Boost. As you can’t remove the battery it’s impossible to swap it out for a spare or even upgrade to something more powerful.
  • No hard restart if the phone freezes as you can’t whip the battery out, you’ll just have to wait for the battery to die or hope the manual restart works.
  • Water damage. Ok, this one is a little on both advantage and disadvantage because it’s difficult to prove, but in our experience, getting water in a non-removable sealed phone is terrible. Unlike a removable battery, where you can attempt to dry out the innards before the battery can short the phone, sealed units with non-removable batteries struggle to dry out before damage is done.ebuyer-logoDual SIM mobile title

  1. – “No Battery Boost.” I wouldn’t even advise to change the battery as pretty much every battery you can buy online or outside is most likely a fake. Just book the phone into repair and they will replace it for you or order the battery directly from the manufacturer. Also it’s not advised to use generic or 3rd party battery as if anything goes wrong with the phone, it wouldn’t fall under warranty. They would know with if they look into the diagnostics data your phone would generate.

    – “No hard restart”
    Android: Hold down the power button and volume down for 10 second
    iOS: Hold down power and home button for 10 second

    – “Water damage”/”Easy to dry” no point, that instantly voids the warranty as there are indicators if it has been in contact with water.

    – “Battery issues”
    Just book your phone in for repair and save yourself the trouble in doing it yourself as one it voids the warranty and two most likely damage the phone in the process.

  2. I’m all for having a quickly replaceable battery. Having a dangling power bank is so ungainly and clumpy and such things can easily damage the delicate soldering connections that hold said socket to the phones PCB.

    With my Galaxy Note the back clicks off in a second, the battery is swapped out for the new fully charged one and the back clicks on again in another 3 seconds. Done, sorted, neat. Who would ever buy a phone with a sealed in battery, huh? Or a phone without an SD card slot huh? But people do, people who generally don’t plan to far ahead.

  3. I was very sceptical about getting a non removable battery when looking for replacements for my Galaxy S2.

    I went for the Sony Xperia Z2 for it’s waterproofing and noise cancelling headphones. To be honest, after 18 months the battery still lasts two days quite happily and to dat I have never had to force restart it, unlike the S2 which needed it a few times over it’s lifetime.

  4. Removable batteries are the best PROVIDED THAT YOU CAN GET A NEW ONE!

    I used to have an Aldi builders phone (dual SIM) that was very rugged and also water resistant. It was one of the few phones that I have owned that didn’t break or suffer from water damage. Eventually its battery died but the only way to get a new one was to buy a complete new phone! Duh!

    Oh by the way my Samsung Solid wasn’t as its plastic window was too thin, too flimsy and it broke. I was going to make a new window from 2 mm thick “Lexan” polycarbonate but I never got round to it. Decades ago, tests at work showed that 2 mm thick Lexan would stop a .22 air-rifle pellet at point blank range. The impact just made a pimple on Lexan but “Perspex” that was thicker would shatter in the same test. Lexan could be cut with a metal guillotine which saved time and even though it cost more than Perspex the saving of time made it cost-effective. I can only assume that the phone manufacturers are not using Lexan because they don’t want the phones to last.

    I now use a Samsung Cobble GT-E1150i One that I dropped in the dark and the rain was found the next day but it had been run-over by a car. The battery cover had gone, the battery was bent and the phone didn’t ring anymore. After it had been dried-out it came back to life and it still had all my stored numbers and messages. Beat that!

    I used to like the Motorola Razr range of phones but these are extremely susceptible to water damage. I have however sailed over to the Isle-of-Wight in a rather wet dinghy keeping my Razr in a condom.This kept it dry but it made a greasy mess.

  5. I’m all for removable batteries. I have a charging cradle for my S5, so the batteries charge in that. I have three batteries in rotation and always carry a spare in my pocket, just in case. I never have to plug my phone in to recharge.
    Spare for my wife’s iPhone – £59
    Spare battery for my S5 – £11 from Amazon. If you’re worried about fake batteries, simply read the peer reviews for them.

  6. I walked the GR20 (long distance mountain trail) on Corsica in 2014 and couldn’t have done it without a few spare fully charged batteries. Far less weight and volume than a phone-charging battery and far more reliable than a solar charger (despite blazing sunshine).
    If you want to sit around in a city all of your life then I suppose a sealed unit is great, but if you want to get out and do something then sealed is not the way to go. Oh, yes, you don’t have to be active outside of a city, you can just sit and watch your battery drain while it hunts for a signal.

  7. I have a micromax canvas spark 3 which is non removable battery.
    So what u think i have wrong or right disison?

  8. For me the advantage of a removable battery is that if I forget or am unable to top up my phone, no problem. I keep a fully charged spare battery to swap over and I’m back in business in seconds. The flat battery is recharged separately. Spare battery and charger cost £12 on Amazon.

  9. Hey non removable is my great choice bse of long battery life .i mean not bulky less spares, name it.

  10. “ADVANTAGE” of Non-Removable
    Single frames or ‘unibody design’ are usually more solid than phones with battery ‘doors’ and often look far sleeker.
    Is this an advantage?
    No not for me. F**K Unibody design. A phone that are thick with removable battery is better than some “UNIBODY DESIGN” s**t. I don’t get the s**t with the “UNIBODY DESIGN’ thing, what so great about it?

  11. Don’t like non removable batteries, what’s this bull about them lasting longer? All batteries are measured in mah so a non removable of say 4000mah is not going to last longer than a removable battery of 4000-5000 mah.
    Got an Alcatel 4 6″ with built in battery but when it gets low when your outdoors have to carry a power bank around to charge it.

  12. In my opinion, companies are making money with built in battery. Correct me if I m wrong. In electronic devices which components or parts are based on time? I think only battery. In the market, People pay for nearly 1000$ in order to get good devices. Are the people really love to use them only for two years? E.g., I bought Sony MP3 player W series and it was last for 5 years. But I have no idea ,how many hours exactly did I use for that device? End up i opened it up and check with 3.7V laptop battery. Its Worked. So, devices it self is no issue at all and only battery although 5 years old. During this 5 years, they come out with a lot of new items. So are you going to search suitable battery for replacement or buy new one? What will you do ?
    In addition, most of the phone service providers are making contract only for two years. Cos they know that or they will convince people to buy new phone with new technology in two years time. So, as long battery last for two years is good enough for the company.
    So my point here is, please buy the electronic devices in following way.
    1) buy with removable battery or user replaceable battery if you intend to use more than two years.
    2) buy with built in battery if you like to change or you want to taste to new technology in every two years time.
    Take note nowadays most of the devices are come with non removable batteries. Finally, I would like to ask manufacturers to come out with affordable price solution and place where easy to change their battery for customer who really wants to use their device for very long. Please don’t advice them to buy new item as it was old and so ever.

  13. i always bought a power batteries for my mobiles in the last 6 years. first thing i do bin the 6 hours only thing.
    i have internet, eBay, amazon, Facebook and everything else running 24/7. i need a powerful battery
    i run a 3 times bigger power battery on my note 4 to supply enough power for at least 24 hours use.
    what good is a non removable battery for me ?

    i had to send my Samsung tab back after 4 month to get it repaired because the battery failed.
    would cost unnecessary money to Samsung if it where out of warranty.
    unless you a weekender on mobiles or don’t use the potential integrated batteries it is crap and the mobile becomes useless without any chance of getting some money out of it after some years.

  14. “Funny” when people think it is somekinda advantage to have inbuilt.

    My expensive Sony z5 had inbuilt.
    Battery lasted only 1-2 days in their so called ultrastamina (no internet, no downloaded apps only simple phonefunktions and preinstalled apps on).
    Warranty only 6 months for battery.

    I now bought a dualsim Moto G5.
    I bought the cheaper version.
    If they had put removable to their flagship I had bought that model….

    I have been a Sony man but not anymore!!

  15. I have always been a Samsung man, but not any more. Why anyone would want a product of any kind with a non removable battery is a mystery to me.
    I can see NO advantages at all, except for the manufacturer.
    The whole concept is to force customer to buy their own battery, or renew the whole phone.
    The fact is that it is commercial GREED. (The same principal as chipped ink cartridges in printers).
    I am just in the process of replacing my own phone. There is NO WAY that I will be ‘conned’ by Samsung into buying one of theirs. (Nor any other company who tries to rip me off)
    The problem is that consumers have too much money and not enough sense.
    If we all refused to fall for the manufacturers tactics, they would soon change their minds.
