I probably will stick with my LG G3 because of the bad news that S6 lost an option to replace battery, though the S6 does look great in my eyes. Cannot decide yet. As for a non-removable phone, is there any ways to double the battery life since we cannot simply swap extended batteries? Ive seen extended battery case on mpj. Will this kind of accessory do any good?
Galaxy S6 does look great in my eyes but...

£600 is a high price tag, yes the phone is nice but not sure it's worth that, such a small battery is worrying especially if you're going to be away from a power source for a full day.
Yes it charges quickly, but we don't want to be having to charge it more than once a day really.

God, do people still swap batteries?
There is no need in this day and age.
Lithium likes being charged little and often so just make sure you have a few chargers around the house and one in the car.
I also carry a spare mains USB charger in the car, just in case.

You CAN charge them more often than once a day.
With Lithium it's not about how many "times" you have plugged it in, rather the amount of charge cycles.
So charging it 20% 5 times is one charge cycle.

And for when you are not around the house at all during the day and don't own a car?
I know you can get power bank charger things (I have a few myself) but they aren't very convenient if you are out and about. Much easier to have a fully charged battery on you that you can quickly swap around half way through the day.
Another throwback myth from the days of Ni-Cad and Ni-Mh is that you should drain the battery as much as possible and charge to 100% often.
This is NOT the case with Lithium.
You should try not to let a Lithium go below 20% before charging and at least unplug it as soon as it says 100% or just before.
When a battery meter says 100% it's actually more like 80-85%. It will charge to the full 100% if you leave it going a bit longer.
This will give you more usage but will shorten the battery's life.
I used to charge my iPhone over night. bad idea. Now I charge for half an hour at breakfast, then take it to the office and plug it into the USB hub for however long I'm there and then continue charging in the car on the way to a job and so on.
There is a noticeable improvement in battery life.
It's hard to get out of that old way of doing things but Lithiums don't like it at all.

Some people do. I do when im on holiday as its far easier than finding a charging point or going back to the apartment to charge it.
Small battery won't be an issue for me 99% of the time as I work in an office where I can charge it all day if need be, then when I get home. But I think for that price tag we should be getting something with a bit more juice.
What worries me is will it last a whole day say if you go out somewhere for a day out, or another situation where you'd be away from any kind of power source for a full 24 hours.

I think Samsung are banking on coffee shops and the like rolling out wireless charging so you will be able to top up the battery even when you are out for the whole day. Of course we are no where near there yet, but if we do get there, then that will be a much much better situation than having to rely on power bank chargers or swapping batteries. I just think they are a bit too early!

You got me there..
Both good points!
Oh and while I'm on my battery charging high horse......... 
While you shouldn't discharge Lithium completely as I said, it doesn't hurt to do it once in a while, say, every 30-40 charges or so.
This is because sometimes, constantly partial charging them can cause "Digital memory effect" where rather than the battery being affected, the charging and calibration circuitry gets confused and so becomes inaccurate.
A full discharge and recharge will re-calibrate it without doing too much damage to the battery.

But all of this is done by the inbuilt software for charging the battery! Its absolutely not needed these days to do this with a battery.
I charge mine every night and always have done and i've never once had an issue with batteries.

Is that the case for Li-Ion ? We used to do that for NiCad and NiMH all the time.

Yes I know, but software is software and you have probably seen post on here where people are saying their batteries are suddenly not lasting long.
I'm willing to bet in a number of these cases a full discharge and recharge would fix it.
It's not the battery not lasting long, it's the battery meter showing an incorrect level.
There are a number of specialist battery sites you can find where they state that the software can sometimes get confused (after a lot of partial charges) and it just needs jogging back to normality.
I'm not arguing with you as what you say is absolutely correct most of the time.

Yeah, see my reply to Stiggles.
I just said it didn't hurt to do it but if the battery is lasting as it should then you wouldn't need to.
According to this post over on XDA, the review units are running samsung modem which isn't as optimized as the Qualcomm one we should get over here.
Although I'm not convinced that would make much, if any difference

How does a full discharge cycle recalibrate anything if you don't have root? I have done this with one of the apps but you do need to be rooted. I will say that messing with the battery stats has never worked for me but maybe there was nothing to fix.
What do you mean, rooted?
Do you mean a factory reset of the device?
If so the OS has nothing to do with the battery at all.
A smart Lithium battery is actually 2 parts.
A chemical battery (the battery itself) and a digital battery (the actual charging and calibration circuitry).
These are both independent of the operating system of the device.
The OS (iOS or Android for example) simply pass on the information from the digital battery and display it for you as a battery meter.
If the digital battery is showing an inaccurate measurement, so will the battery meter.
While the handset has a charging circuit with all the fast/trickle and overcharge protection gubbins, this is not controlled by the OS at all.
If it was it wouldn't be possible to turn your device right off and still have it charge ok, which all phones do fine.
All I'm trying to say is that sometimes the chemical and digital sides get out of step from their original settings and doing a full discharge will set the low flag and then a full charge will set the high flag and this should cause your meter to be more accurate.
All this going on inside the battery though, nothing to do with the OS.

Yet, for a high end device we still hear nothing to claim good battery longevity, such as 1000 charges.
I'd guess a daily gentle charge to about 70% might help here, but a 'battery protect charge' setting would go a long way to making these sealed batteries last.
With a laptop it was norm to be on mains for most of the time but phones it is battery running near 100% of the time.

That's one for the chemistry department, not the electronics/phone people.

Maybe why Apple hasn't (yet?) bought into the "fast charging" or "wireless charging" ideas.

Quite. Corporate laptop models from Dell, Lenovo etc have battery management applications that let you choose what to do when at 100% for those laptops that spend their life plugged in.

Nope, Apple claimed 1000 charges for their high end laptops.
I can't see why we can't have the same for phones. It should be far easier considering they are all a far simpler one cell battery.
And HP also market long life batteries, I assume for HP Compaq laptops only.
edit Seemingly they made by 'Boston Power' so that same source might be for Apple too.
Bit off topic but my work laptop is an HP and it seems to stop charging when it hits 100%, drops down to 95% then recharges again.
I dunno if this is expected or not, but that's what it's always done and it hasn't burst into flames or anything! yet.....

There's no Qualcomm version afaik, just Exynos. Also your XDA link is invalid.
Looks like that post has been removed for some reason...
Sorry, getting my SoC's mixed up, word is there is a different, more optimized modem in the retail version than the display ones that have been given to reviewers.
