It is recommended to adopt replaceable battery to solve the issues of battery life, dimension and weight. On the contrary, we can see the built-in lithium battery is more widely used than the replaceable one in most of the current digital electronic products. There are several reasons:

1. With the same dimension, the capacity of replaceable battery design would be smaller than that of the built-in one since replaceable design takes up as large as 30% to 40% of the total capacity. 

2. Owing to its replaceable battery cover and internal battery connecting parts, the replaceable design has higher defective rates.

3. The easy-open cover increases the difficulty to its refinement of manufacture.

4. If the USB is used as the power supply, then mobile charger can easily solve the battery life issue.

5. If is to use the replaceable battery, then more factors need to consider, such as the design, manufacture and marketing of its desktop charger. Moreover, the price will be higher to come with one desktop charger, while the user experience can’t be reached if without.

6. Lastly, it is widely believed that the replaceable battery would be much more convenient for the end-users to exchange in case of faulty. While actually, the result would be the same.
For the built-in battery, it would last for several years with proper usage. After several years of using, it can be returned to factory for replacement in need of further using.
 
For replaceable battery, if it is not a universal one, it would be very hard to find an applicable battery on the market after several years of usage if the customer hadn’t purchased another backup battery with the device. In this case, the customer still needs to contact the manufacturer to buy the replaceable battery with some costs.

Replaceable battery is convenient.

No replaceable battery at all... you were totally right about that James.
Plastic cased phones lipos will not be available long time and 3.7 lipos cells forever.
The X3 was perfect.
Do it again.

I don't see the problem with replaceable battery on lots of phone dating way back to when it was first introduced.

Returning it to factory may seems easy enough but how about for people who lives in country where that factory doesn't exist? Do they have to pay two way shipping + the cost of the battery? From what I see it's usually easy enough to find battery compatible with the device you have, it doesn't have to be exactly the same.

I wouldn't mind replace the lithium battery by my self in a couple of years if they still are available to purchase.

For me I don't like the idea to carry around another charger or extra battery pack.

I bought a power bank that I can use with x3, phone and the wall/car charger

If it's 8 hours plus on play time, please non replaceable so I build quality will be top notch. If under 8 or 7 then replaceable but I hope that wouldn't suffer BQ so much.

When the battery eventually fails on the X3, can it be replaced ? Guess I should also asked that about my E07 andes.

I would be willing to mail it somwhere, though I am dangerous with a screwdriver or an appropriate tool (spudge ?).

you can send back to us to replace it or we can sell a battery to you and you can ask someone change it. it is not so difficult.

I would like to have a replaceable battery, but! It mustn't be easily replaceble!
I would suggest not to use glue at least. So, that it it could be replaced by a master.

Thank you, James, for the interesting and clear explanation of the trade-offs between replaceable and non-replaceable batteries.
 
I think we all instinctively prefer replaceable batteries, but when the trade-offs are set out clearly, it is easier to understand the appeal of non-replaceable batteries.  On the other hand, it would be nice if the 'non-replaceable' battery were still relatively easy to replace if a user wanted to 'go under the hood' and replace the battery in the future when it had gone through so many cycles as to no longer have much life between charges.
 
My request, humble as it is, however, is that if you give us a fixed battery, as it seems you will, please go over the ten hour standard you have set yourself as being appropriate.  As you know, classic iPods go over 20 hours of battery life, and particularly for those of us who use our players when traveling, even if our flying time is less than ten hours, by the time you add in extra time waiting in airports, changing flights, etc, it is very easy to use up 10 hours of battery.
 
I'd much rather accept another 10 or 20 grams of weight, and another cubic centimeter or so of space, if it would give appreciable extra battery life.  That's the key thing for me.

Does that apply to the X5 as well?  Thanks!
Cheers!
