Thank God, my cell phone stopped the bullet! OWWWWWW! It burns! It burns!

Yeah, people don't realize how much energy is in a battery and that Lithium Ion is very flamable. However, you also have to work hard to make a battery fail that spectacularly. They have internal protections against that. But sure, keep stabbing and eventually you'll circumvent the protections.

Wow, Not sure what'd be worse, getting the knife in your flesh or having that battery burn a hole through you. It least the wound should be sterilized if burned

, but probably with deadly gasses. Decisions, decisions......

Which is why, you can understand, a lithium ion battery fire on an airplane is such a concern. There's was some concern that a shipment of Lion batteries on the missing Malaysian flight MH370 may have have caused a fire.

Lion batteries - unlike most other batteries - can and will release ALL their energy in a few seconds. Most other types of batteries can't due to limitations of the internal chemistries or physical design. This is what makes Lion batteries so good for high energy demand devices like power tools, electric cars, drones, etc.

Add to that the fact that Lion batteries are highly flammable, and well, yeah, you have the stabbing blowtorch of death.

Since there was a spate of defective early design batteries spontaneously shorting out internally and exploding in laptops and phones, modern cells have internal chemical fuses that open when an internal cell short circuits. By stabbing the pack repeatedly, they're getting lucky and damaging a cell so badly that the internal protections don't work.

I wonder if that's part of the reason why the upcoming Samsung Galaxy S6 won't have an accessible, replaceable battery for the first time (compared to earlier Galaxy phones).
I'm getting one in a couple months but I've never had to replace the battery in my S4 so that's not going to bother me.

That's the trend now so that they can squeeze the battery in there and not have to worry about making it user-replaceable. SUcks though when you DO decide you want to swap out the battery once it's lost its performance.

That has more to do with allowing them to make the phone thinner and cram more in there. A glued in battery takes up less space. Sadly it's the trend now. A good phone repair shop can still replace the battery, but it's a job and a half.

The old Droid Maxx that I had a few months back, came with a battery that you could not replace, even though instructions could be found on the net to take the phone completely apart to access it.
The problem with the Droid Maxx is if you let the energy level go to zero, there was a good chance the phone became a brick.
I have a Samsung S5 which is great, because I can replace the battery when it needs to be replaced.

I agree about being able to replace a battery. That is simply a deal breaker to me if I cannot. Most tablets make it hard to do so, but for a phone, it should be standard to be able to replace it.

It's because of the trend towards thinner phones. My argument is phones are more than thin enough. Now I want more battery life. Instead of battery life they keep giving us more CPU cores (do I REALLY need a quad core processor on a phone?) which just eats the ever shrinking battery.

You're not going to see too many phones anymore with battery compartments - they waste too much space, but batteries SHOULD have an inline connector and a case that can easily be pried apart. Instead they solder the battery pack to the board and glue the whole thing together now.

I remember back when you could snap out a battery and get bigger ones that bulged a little bit. Agree on the quad core foolishness.

Now I don't pay for my phone... and Its a flip phone, But at the airports I see it all the time, I can understand in the evening seeing it, but in the morning people are all crammed around outlets charging their phones! I some times can go a whole week before needing to recharge my phone.

I kinda want a smart phone and would could deal with it only lasting 24 hours. I would charge it every night and I don't think I would have a problem with having to do it if I knew it would easily last a day with no problems. I just don't get whats so damn important that you need to be on your phone all the time that causes it to be dead within hours.

I have a Archos game pad and it's nice. I only bought it to use as a remote for model trains and my tv and I have a level app on it I use for setting up pinball machines. I know when I play games on it it will barely last a day.

Under normal use, my Moto-X is usually down to 50% at the end of the day (normal being defined as several short calls and texts a day, some web browsing during lunch or waiting in a doctor's office).

GPS will suck the battery dry in no time, but if I use the GPS in the car I plug the phone into the charger.

I have few background services running, however I have my screen brightness at max (#1 battery eater). The automatic brightness never works for me.

I charge every night without fail. It goes on the nightstand with my wallet, watch and keys and gets plugged in as soon as I get home.

What has been a LONG time coming is factory charging mat support. It's 2014 for cry out loud! Why the hell are we still plugging wires into these things to charge them?

Newer phones have or will have that option when released soon.

Didn't apple come out with the Wave charging technology?
