Removable battery - do we rlly need it?


With every relse of a new smartphone the same question is asked - will it have removable battery? If you believe that removable batteries are a "must have" nowadays, plse keep rding. I hope you'll change your mind!
First of all - there is a solution. Battery banks seems to be a grt alternative for removable batteries. You can check my review of Battery Bank here. It works with every device equipped with micro-USB port. Now let's compare both solutions.Capacity
Galaxy S3 has a removable battery with capacity of 2100mAh. Typical battery bank has a capacity of 6000mAh. This mns, that Galaxy S3 can be charged almost 3 times with such battery bank! If you are going to use your smartphone hvily the whole day, only one backup battery might be not enough for you. With battery bank you can start your day with more then 8000mAh on board (battery inside device + battery bank).
Conclusion: 2300mAh vs. 6000mAhWinner: battery bank

SizeTypical smartphone battery dimensions are around 6,3 x 5,0 x 0,5. Battery bank I was tested is of course bigger - 9,7 x 4,2 x 2,2. Is it rlly a disadvantage? I don't think so. It's small enough to be inserted into a pocket of your jns or jacket. I think there are even smaller battery banks available on the market, so the size shouldn't be a problem here. Also, removable batteries are indeed smaller, but keep in mind their capacity is twice/triply lower.
Conclusion:6,3 x 5,0 x 0,5vs9,7 x 4,2 x 2,2Winner: removable battery
ChargingBattery bank can be charged regardless of device battery. It has its own USB cable and charging port, so you can charge both devices - smartphone and battery bank at the same time. What about removable batteries? Well, if you don't have a removable battery charger (which costs extra money of course!) you will have to charge battery inside your device first, then switch batteries and charge the backup battery. The risk of braking battery cover latches is quite big, especially when it comes to plastic, which has its own lifetime and bending abilities. It seems that battery bank in this case is much moreconvenient andcomfortable.
Conclusion: charging inside the device vs.independent chargingWinner: battery bank
PriceOriginal backup battery price is about $30. Yes, I know you can find non-original replacements for $10 as well, but let's compare only original parts. Typical battery bank costs is around $40 - $80($75 for Battery Bank). However these prices vary from place to place and may be slightly different in your country, keep that in mind. Comparing 1:1 it's sy to see that external batteries are indeed cer. But to make the comparison fair, we need to establish the price/capacity relationship. 1mAh from 2300mAh backup battery ($30) is a cost of about $0,0130, while1mAh from 6000mAh battery bank ($75) costs about $0,0125.
Conclusion: $0,0130 vs. $0,0125Winner: battery bank
DesignWhen spking about the design I mostly think about device design. However, battery banks looks definitely better and more aesthetic than regular removable batteries. Having a removable battery back cover doesn't allow uni-body construction, like One has. Design is a matter of taste, but personally I prefer uni-body construction over having a plastic back cover. But again - it's a matter of taste, so no winner here.
Conclusion: plastic back cover vs. uni-body constructionWinner: draw
UsabilityPractical approach is also important. Driving a car or sitting in a crowded bus might be a situation when your device is out of power. Now imagine you need to: 1) take out your battery backup, 2) turn off the device, 3) remove the back cover, 4) replace the battery, 5) close the back cover, 6) turn on the device, 7) hide your primary battery. So... 7 steps including theinevitability of turning off the device. With battery bank you just need to take it out and plug into the device. That's it. No need to turn on/off ordisassemble your device. Keep in mind that battery bank doesn't work only as external battery, it is mainly a battery charger, so after some time you can hide it back.
Conclusion: 7 steps to change battery vs. take out and plug inWinner: battery bank
CompatibilityExternal batteries are not compatible between devices. You can't use Galaxy Note II battery in Galaxy S3. You can't use Sensation battery in One S. If you buy backup battery for your particular device, you'll probably sell it together with the device or give it as free bonus one day.Battery bank is compatible with every device equipped with micro-USB port and can be your life-companion for yrs. However, you should be aware that battery bank might not be able to charge your tablet.
Conclusion: lack of compatibility with other devices vs. compatibility with all micro-USB smartWinner: battery bank

Device lifetime (added 23-03-2013)
Due to many comments under this article I decided to agree with one point that was very often mentioned by users preferring removable battery. However, I think it needs some bigger explanation. It is a fact, that having non removable battery results in lack of possibility to exchange it for new one, once the old battery can't give your device enough power anymore. But is it rlly a problem? I took the warranty statements from my One X+ and I found nothing about limited warranty for battery (like have - only 6 months). This mns, that once battery is non removable, it doesn't have shorter warranty. So in my case battery is under 24-months warranty service. I think that is a positive aspect for the consumer, right? In some cases it might be also 12-months, but it depends on particular law regulations in ch country.

Conclusion: removable battery with 6-months warranty vs. non-removable battery with 12/24-months warranty -both solutions have some advantages
Winner: draw

Possibility to reset the device (added 25-03-2013)
One more egory added. Very often I hr that possibility to remove the battery is the only way to reset the device once it's not rcting anymore and system just hanged. This is not true. Every device have ability to reset the system using hardware . In most cases it's a combination of 3 buttons:power+ volume up + volume down. You need to hold these buttons for about 5-20 seconds, depends on the device. Even if your device has a removable battery, it is better to use above combination to avoid brking the plastic back cover latches.

Conclusion:you can reset your device no matter if it has removable battery or notWinner: draw

So what's the score? Battery bank won in 5 comparisons, external battery in 1 comparison and there were also 3 draws. For me, personally, battery banks are better replacement for external batteries. It gives you bigger capacity for the same prize, extended usability and it looks better.
