non-removable mobile phone battery good or bad

Best type of mobile phone battery, non-removable battery is good or bad

Both removable and non-removable batteries in mobile phones have their advantages and disadvantages. One of the biggest problems with non-removable battery phones was what to do if a phone with non-removable battery hangs. This non-removable battery phone hang problem with older phones, with no way to force a shut down a hung phone is a thing of the past.
Now just by keeping the power on switch pressed for 10 seconds, will reboot a hung phone. Some phones require the power button and volume button to be pressed together for 10 seconds to restart a frozen phone. The major advantages and disadvantages of having non-removable batteries are detailed below.

Non-removable battery pros and cons

Advantages and disadvantages of non-removable battery in mobile smart phones are as follows:

What is good about inbuilt battery in mobile phones

  1. Non-removable battery phones can be built much thinner and more robust because the inbuilt battery in mobile phone can be shaped to fit the profile of the phone.
  2. The internal parts of the phone with inbuilt battery are better sealed and protected against water and dust
  3. In case of dropping a non-removable battery phone, since all the internal parts are tightly fitted there is less damage to the phone than in the case of a dropped phone with replaceable battery whose back cover and battery will all come out. In case the cell phone dropped on a hard wet surface with puddles of water, the survival rate of the cell phone with inbuilt battery will be much greater.

Problems with non-removable battery phones

  1. The main problem with non-removable battery phones was how to reset phone with non-removable battery when the phone froze up, that is when the mobile cell phone gets stuck and hangs up with none of the keyboard keys working. This was a serious problem with non-removable battery phones before, but now this problem has been solved with keyboard shortcuts to switch off, reset and restart the non-removable battery phone.
  2. You cannot swap a dead battery of the non-removable battery phone with a fresh fully charged battery as could be done with a phone with a removable battery. This was a major problem of the phone with non-removable battery phones in the days before the advent of the universal power bank backup battery charger.
  3. The other minor problem is how to replace non-removable battery in mobile in the event the battery came to the end of its life. This can only be done in the service center of the phone manufacturer, it is not a serious problem considering that the non-removable battery phone's battery will last at least two years before it needs replacement.

Non Removable Battery Advantages and Disadvantages for Mobile Phones

You are probably well aware of the fact that many phone comes with a non-removable battery, which the phone doesn’t offer a away for you to  replace the battery and use a spare battery. The fact is that most people don’t carry nor they want to carry a second battery with them. I agree that having an option to do so is a good.  Some say that by removing the battery we are actually reducing the life span of the device due to dust entering the battery chamber and damage the phone and changing batteries reduce its lifespan.

I’ve read many negative opinions about the HTC One from people complaining about not having the option to replace the battery. Is it a big issue or not – in this article I want to present to you some of the advantages and disadvantages of each approach, and you’ll decide whether you are convinced or not.
Removable battery gives you convenience and in fact some people do carry an extra battery with them. There are options to extend the battery capacity even double it with a battery case. For example, you can use the Mophie Juice Pack for the HTC One ($99.95)  that doubles the battery life of the HTC One. As you know, the HTC One doesn’t have a removable battery and many people complained about it.  The disadvantage is that the cover thickens the phone profile. It’s not too bad though and a hard case with integrated rechargeable battery might be your best bet here.
Take a look at the next image and see the difference in size for yourself:
HTC One Mophie JuicePack
HTC One Mophie JuicePack – Before & After
You can see that the battery case adds to the overall size of the phone quote a lot, but you get twice the battery life  (HTC One battery life) and I think that for some people that’s more important than aesthetics. The great thing is that you can still continue to charge and sync your phone via USB and the lens and LED flash visibility are not compromised in any way.
The you the truth, I never liked the flimsy back covers of my phone. I didn’t like when I drop the phone the cover detaches from the phone and I need to attach it again.  I also think that in some cases this helps protect the phone, especially if you dropped the phone accidentally in the sand or where there are lots of dust and other particles which can actually damage your phone if they get inside it.
No doubt that a unibody phone design looks better and I think that many people love it. A slick aluminum zero-gap aluminum phone looks and feels great in the hands. You’l have less parts that can break when you drop the phone, less gaps for dust to enter the phone itself.
Non-removable battery / Phones with non-removable battery advantages:
  • Less parts that can break
  • Phone manufacturer can make their phone slimmer
  • Battery door can break
  • Less gaps from which dust can get into the device
  • By removing the device you let dust and humid inside your phone that can damage it, especially if left open for a long period of time
  • Zero-gap unibody design looks slick and more solid
  • In some phones that also means lack of micro SD card slot too (HTC One doesn’t have a microSD card slot)
  • There is always an option to purchase a battery cover, but that adds bulkiness to the phone and doesn’t come cheap (Samsung Galaxy S4 battery costs between $10-15 depends on the brand and capacity)
It seems that most people aren’t convinced with that, and for them the cons outweigh the pros. The two most concerns are:
  • What happens a year when my battery performance is degraded and I want to replace it with a better one? (does the phone manufacturer can replace that battery?)
  • What happens when my phone freezes? With a removable battery I can just take the battery out and put it back (hard reset?)
  • Not having the option to use a spare battery, which is also the cheapest option out there
Some people the first thing that they do is to purchase a spare battery. Those battery are cheap so people don’t mind buying a second battery. In case that the first one is out, you can easily put the second battery and continue using your phone. Great when you are on the move and far away from a place where you can charge your phone. It’s worth mentioning that with phones with removable battery you also have the option to use an extended large-capacity battery with a dedicated cover. For example, you can purchase the Hyperion Samsung Galaxy S4 5200 mAh extended battery + black back cover for only $17.99 on Amazon. A cheap and effective solution to extend your phone’s battery life.
The advantages of having a removable battery/cover?
  • Easy to replace the battery with a newer on when the battery performance decreases
  • Can buy a spare second battery and use it when the first one it out of power
  • Most of those phones do offer a microSD card slot

Some people are carrying a battery bank with them so the can charger their phone on the go. Take the  EasyAcc 12000mAh 2 USB external battery pack charger power bank . It’s a universal power pack comes with either two or four USB ports, so you can charge even several devices at the same time. It’s compatible with the Apple iPad Mini, iPad 4 2 2, Android tablets, iPhone 5/4S/4/3Gs, Samsung Galaxy S4 / S3, S2, Blackberry devices, cameras, MP4 players, you name it. For a price of around $40, you just can’t go wrong.  According to the manufacturer, it will supply about 600%~%700 of iPhone 4 battery life and 200%~250 of Google Nexus 7 battery life. It’s the perfect companion for a long flight, when traveling on a bus or whenever you need that extra power to last all day long on heavy multimedia and wireless usage.
So you can see that there are very affordable options out there.  The most easiest, more convenient and cost effective option is to have a phone with a removable battery/cover. All you have to do is to buy a cheap spare battery and get it over with. For most people this will be more than enough. People don’t like buying a phone and be worries about what happens in the future. They want to rest assured that they phone’s battery will continue to operate at high capacity and offer optimal performance even after a few months after purchasing the device.
Even more than that, at some point in time you might consider selling your phone in second hand website. Having a non-removable battery might make those phones less attractive for buyers that are searching to buy a second hand phone. Regarding the HTC One, I still didn’t find an official answer whether it’s possible to send the phone to the official lab for battery replacement or not. If you have that information, please comment below.
Remember, batteries wear out long before anything else on the phone. Some people don’t replace their phone every year and can hold it for even 3 to 4 years. For many people it’s easier to just get a phone with a removable battery and not worry about all this nonsense. Other people don’t mind or even prefer having a phone with a non-removable battery as they will upgrade to a newer model anyway after a year.
I also think that for businessmen, having a spare battery is the best option. When it comes to business, there are crucial times that you just can’t offer to be unavailable. I don’t know how it will effect the HTC One for people who use their phone for business, but that’s something to consider too I think.
Everyone of us makes its own choice. I think that most people prefer having a removable battery even with all those cons that I’ve mentioned. I personally have a phone with a removable battery that fell dozen of times, got dust in it and even after a mild abuse is still working perfectly fine and battery life is still in its best. So for me that’s some kind of evidence that maybe this all non-removable battery advantages just doesn’t stick (at least from my own experience).

I am afraid it is purely and solely a commercial strategy.

Up to now,  technologies were rapidly changing,  and newest phone generations were vastly better than the previous one. Look behind: screen sizes,  DPIs, android /iOS  features,  touch screens,  electromagnetic radiation limits,  gprs-2g-3g-4g.  All of this  occurred in a decade or so, but it was the first decade of the smartphone Era. Remember when the 4.77MHz IBM pc came out?

Up to now,  users had very good reasons to buy the next phone generation,  and invested  a significant amount of their earnings into it.

Network standards were changing too,  and phones had to be changed to cope with new data protocols, taking significant steps forward in data bandwidth.

However, network providers will hardly  keep increasing  speed as they did in the past,  since the available bandwidth for phone communications is being saturated,  and the demand for faster and faster connections slows down too.

So you are not compelled in buying a new phone because of new networks arriving soon. Where smartphones could improve? Your existing phone is good enough for 99% of the tasks.

Better DPIs?  Your eyes don't see it. Faster CPU? No need. Larger or smaller screen? All options are available already. Newer software? Just upgrade.

So,  manufacturers need a legal way to avoid people using the same phone over a long  time. In particular, the  smartphone should be thrown away in few years to avoid that the manufacturers market shrinks dramatically. Their need is purely economical: phone manufactures are  kept away from the recurrent revenues of subscriptions that go to the network  providers.

Admittedly, phone manufacturers have found a legal and technical way to limit the lifetime of a phone: a component with a limited lifetime that cannot be replaced.  In theory,  it can be replaced, but in practice it will cost you as much as a new phone and it will be a hassle to do it. Nobody wants to stay anymore without phone for days, so you have a good reason to swap it.   

The argument of reduced phone size and larger battery capacity when the battery is not removable  is simply a fake one: take the galaxy note 5. It has the same dimensions of the galaxy  note 4 and 10% LESS  battery capacity, with the same overall functional features.

We are simply blinded by marketing, and by the common interest of phone manufacturers that need to find a way to survive and keep selling more and more,  as publicly traded companies need.

I own a galaxy note 4, and 3x replaceable batteries with their own charging box and a dual port USB charger : in 2 hours,  I recover the autonomy of a week,  and if a battery approaches its life end, as every battery does,  I replace it for about 15$. It was a marginal investment with respect to the phone purchase,  less than 10% of its price.

My phone is always up and running. If I would run short of juice in the middle of a call (actually never happened to me since I can afford changing the battery approaching 20% charge,  that's actually a great way to keep a long Li-ion  battery lifetime  too) it will take less than a minute to replace the battery and keep going. With a minor investment,  I can use my GPS for long trips without being plugged in. I can watch movies without asking myself where is the next plug, or being ridiculously sitting in front of a power plug.

As users,  we should stand with our demand,  and buy the equipment that fits our need. I am an intensive user of phones,  cannot afford downtime,  and I will buy phones from those manufacturers that offer me a replaceable battery solution. Convince me I am wrong.

ADDENDUM: some comments pointed out that batteries have significantly improved and they don't fail anymore. There is a significant misunderstanding.  Even apple itself declares that batteries have 80%of their capacity after 500 charging cycles, and it is an exponential decay.

This is an intrinsic behavior of Li-ion batteries, and the design performances are not even guaranteed! It depends on temperature and type of use. Not by chance,  companies like Apple prevent you to count your charging cycles without jailbreak,  they could allow you to do it but... Better not!

So, you are now aware that  your telephone is designed to loose value from day one,  and if you charge every night after 2 years you will have lost one quarter of your autonomy. If you are happy with it, fine with me - but don't expect me to buy your used phone with a non removable battery!
