Now I hope samsung will bring back the removable battery. The only reason I can still use my note 3 is because I was able to easily replace the battery with a new one. In fact all phones should have accessible batteries as the battery is in my opinion a consumable which will need replacing at some point.

> The only reason I can still use my note 3 is because I was able to easily replace the battery with a new one. that is exactly why you won't see removable batteries in new phones; how else do you drive the new buy cycle every 2 years? as speed and features, phones are pretty much 2010-desktops; good enough for what they do so they don't need replacement on the new hardware generation

If you want me to buy another phone every year or two you will need to provide me with something I want and not force me because the old one is now broke. Especially at a price tag of almost $1000.

I didn't buy the note 5 not because of the fixed battery but because they removed the SD slot.

That's why I switched to the LGV10 -- which has a removable battery. It's successor the V20 also has a removable battery. Nothing beats going from 5% charge to 100% in 15 seconds.

I just wish it was an OLED display and I would be onboard the next day.

> but take the battery out obviously not a mac user

Clearly not. Mac users are used to their laptops actually going to sleep when they shut the lid. My work HP, however, is regularly scorching hot when I get home as it's been on in my backpack the whole time despite me shutting the lid and despite the instruction to 'go to sleep when the lid is closed'. How there's not some sort of thermal cutoff I do not know, but I know for a fact that there is not. Edit: by 'regula…

If this is not caused by the Windows issue mentioned by TeMPOraL, I might have another explanation:

My former notebook (Acer Timeline 1810TZ) used to wake up from a press on any keyboard button, which I was unable to change. The issue here is that with sufficient pressure (e.g. when I was running with the device in a messenger bag), the lid would bend enough to actually press a key and wake up the machine.

My hackish solution was a script that would automatically put the laptop back to sleep a few seconds after waking up, which I then manually killed after intentionally waking the device.

In that case your "small toothpaste" (which is allowed) might not be that either. And you can always dilute it in your air-hostess delivered water if you're so inclined and you just need to have your poison/whatever in liquid form...

The threat they are trying to guard against is binary liquid explosives, where you mix two liquids to make a bomb, so volume does matter. Of course, it's a idiotic way to accomplish their goal anyway, but their goal is idiotic anyway, so it's all security theater anyway.

> binary explosives ...

Please, what a frigging joke. Be cooped up in a small bumpy space for hours trying to create a very touchy explosive.

... hydrogen peroxide, acetone, and sulfuric acid ... put a beaker containing the peroxide / acetone mixture into the ice water bath (Champagne bucket), and start adding the acid, drop by drop, while stirring constantly. Watch the reaction temperature carefully. The mixture will heat, and if it gets too hot, you'll end up with a weak explosive. In fact, if it gets really hot, you'll get a premature explosion possibly sufficient to kill you, but probably no one else.

After a few hours - assuming, by some miracle, that the fumes haven't overcome you or alerted passengers or the flight crew to your activities - you'll have a quantity of TATP with which to carry out your mission. Now all you need to do is dry it for an hour or two.

Is this a Samsung-specific problem, or is it more generally, a lithium ion battery problem (the regulations have always been in place for lion batteries on planes)? I suspect it's the latter -- in which case, it's pretty unfair to single out Samsung. On another note, I've always felt paranoid about keeping my phone in my pocket or having my laptop on my lap, especially if it starts to heat up. I might as well stick a…

The Galaxy Note 7 is being recalled over fires that have actually occurred. So I don't think it's unfair to single them out in this case.

Most models of phone experience reports of the occasional battery fire. Its just at a rate perhaps an order of magnitude less than the GN7. I suspect the fact that Samsung itself issued a recall is probably the main reason the FAA felt they needed to issue some kind of statement.

I wonder why they aren't being banned, the way that hover boards were (though I believe the fire risk for the Note 7 is only present while charging)

Honestly, I've always scratched my head slightly at the fact that one is allowed to travel with an explosive device, so long as it also functions as a battery - yet bottled water is way out . It's trivially easy to make a lithium fire at 45,000 feet. Stamp on/bend an IMR 18450, and you have a torch which will burn through a window. Hell, you could probably just fold your phone in half - most batteries run the full he…

Lol! madaxe on his next flight: "Sir, could you please step over here"

I don't think that's the reason. If your battery is dead, it's easy and cheap to get it replaced nowadays. Not a good enough reason to buy a new phone.

It's psychology: people want an upgrade justification, and the threat of a few days without a phone is enough for most people.

Risk might not be great enough. They're balancing convenience and safety. IIRC the hoverboards had a higher risk because of how many cheap ones burst into flames and people didn't want to use them in flight so it wouldn't bother them if they didn't have them.

The "hoverboards" have a much bigger battery, with far more stored energy, and are also designed such that they can release that energy more quickly since the application requires it. A typical phone has around 10-15Wh capacity, hoverboards are in the 150-100Wh range, and laptop batteries are usually <100Wh; these are also cells which are designed more for long low-current discharges.

Once a battery starts releasing energy "more quickly than intended" it's only going to get quicker until it runs out of energy.

This is actually my #1 fear in flying in 2016. Some rough baggage packing under the plane that damages a laptop battery in the gate checked bag. Every time I fly I watch people gate check bags with laptops and more even after the announcement to "remove all lithium batteries & electronics". I wish more people understood how dangerous this could be and would take 3 minutes to take electronics out and carry them on boa…

Me too. I fly a lot, and the thought of a damaged battery, or somebody leaving their notebook in sleep mode, packed in a suitcase of flammable clothes with all of the other luggage gives me anxiety at times. If I have both laptops with me, I check the heavier one, but take the battery out and carry it on. I fly from Hong Kong to the US quite a bit (16 hours), so alternate landing sites are few and far between. That,…

Flammable clothes is kind of an oxymoron. Pretty much any textile intended to be work gets treated with flame retardants.
