> "replaceable battery"

Can you tell me what is a practical use of a replaceable battery, I've had iPhones for many years and battery does not go bad. Also if in 2+ years you decide to change a battery I doubt you can find an original batter, and will end up with a cheap knockoff which might not work at all.

> "weight"

Heavier phones directly impact usability and even handling in your pocket, holding it while reading will tire your arm sooner, handling it in a pocket will make it look ridiculous by pulling your pants down

All batteries go bad. Science

I always go over the 2 years and for $20 I can buy a Duracell Battery that gets me back to the original life. Lithium Batteries Apple or not ALL Lithium batteries last about 300 to 500 charges.

"Rechargeable Lithium-Ion batteries have a limited life and will gradually lose their capacity to hold a charge. This loss of capacity (aging) is irreversible. As the battery loses capacity, the length of time it will power the product (run time) decreases." http://www.newark.com/pdfs/techarticles/tektronix/LIBMG.pdf

That is not up-to-date information that you have. You can find plenty of batteries keeping 80% of the original charge after 1000 cycles or more.

Yep. I have a mid-2011 MacBook Air and the battery still lasts 3-4 hours, which is reasonably close to the original specs, especially considering 5 years of constant, everyday use.

At 1000 cycles my 2 year old Note4 battery probably still held 80% of it's charge, but it's my go to internet/entertainment device and I charge it 2 or 3 times daily. All the sudden 1000 cycles isn't that many cycles- but who cares when the battery is replacable? This phone should be good for 2 more years so long as I don't drop it in the toilet.

Sometimes it's not about going bad, it's about quick recharge. You can have a backup battery charged and ready for a quick swap. There are portable batteries that charge your main one now though, so the need for this is somewhat mitigated.

[usaphp]

Since his comment mentioned that he does not care about weight and thickness then batter cases is a perfect solution for that, it's easier to purchase a battery case then an original replacement batttery

[kbenson]

Well, in fairness, I think the original comment was meant more to imply that small changes to make it slightly faster, lighter and thinner weren't that important (but a few iterations of that can add up, so I think it's important, even if I don't always opt for that in my new purchases), not that they didn't matter at all. That said, a battery charger is superior to a replacement battery in that it doesn't require a restart, it may be large enough to recharge more than once, it can charge many types of phones/devices, and it can have a nonstandard shape. It's inferior in some ways as well, since it requires being attached for some period to charge the original phone (which can be impractical or annoying in some circumstances).

Also, another important aspect of a removable battery is that some people like it for privacy. If you can't remove your battery, you can't really assume your phone is truly "off". Even if you can, if you really care about that, you would wait a while to make sure any small internal batteries/transistors have used what power they could hold. Other than that, I'm not sure of a way to ensure the baseband processor isn't on[1].

No. Batteries cost next to nothing. Back in the days I had three additional batteries for my Galaxy S 2 and it was amazing. Others in my team frequently needed time at a charger while I could go from 0% to 100% in a minute while on the go.

The batteries came with a charger and were around 10 Euro each.

[usaphp]

So you carried those three additional batteries with you all the time? Honestly how many times a day do you charge your phone? Most phones last full day and I dont have a problem plugging it in at the end of the day to the outlet, instead of carrying a set of batteries with me.

[jff]

Three batteries in a backpack pocket will take up about the same amount of space as a wall-wart plus cable.

> Most phones last full day

I always have to chuckle when that comes up.

[lips]

I carried a G1 with two spare batteries when doing documentary work. It was lovely. I didn't have to hunt for outlets or deal with using the phone while plugged into a battery pack.

If the phone is a widely used model, it's often not difficult to find new-old stock for a while.

I gave this list of "not cares" a several year window of context. It's pretty obvious OP doesn't want a bag-phone, but might be perfectly happy with the form factor of an iphone 4/5. Not a novel complaint.

[usaphp]

Did you tape those batteries to your phone? How did you carry them with you all the time?

[dom0]

The invention is called "pocket" and/or "bag". I think the patents have expired though...

[rubber_duck]

You can buy a portable charger, not as convenient but also designed for carrying around unlike batteries (honestly carrying around an unprecedented fully charged battery in pockets (bag or clothes) sounds dangerous)

[Laforet]

It's not quite like E-cig users and their naked 18650 cells.

[pix64]

No more dangerous than keeping your phone in your pocket or bag.
