LG stepped battery

Two trips to New York City in two weeks — one for Motorola, and another for LG, and one common theme: Why waste space inside the phone when you could fill that void with a little extra battery volume.

Enter the "stepped battery," and it's a simple enough idea. Instead of a single, rectangular-shaped battery, you've got one with a small "step" — and little bit of a hump that gives you a little more juice.

We got an up-close look at LG's "stepped" battery this morning at the G2 launch event, and you can see exactly what they're talking about. LG's using a 3,000 mAh stepped battery in its G2, and the bulge is subtle — maybe not even a full millimeter in thickness — but it's there. And spread it out over a decent size area, and suddenly you gain a bit more capacity.

Motorola's doing the same thing in the Moto X (though with a smaller overall volume at 2,200 mAh), and sure enough, LG confirmed to us that Motorola uses LG batteries in some devices. (That'd be LG Chem, actually, which is a separate business from LG Mobile.) Not a big leap to make there.

This is in contrast to a phone such as the HTC One, which uses a traditionally shaped battery and instead slides the phone's motherboard into that space where the phone curves outward. 

Neither the Moto X or the LG G2, it's worth mentioning, has a removable battery. One way or another, it's a nice, basic change that gets us a few precious extra minutes out of our phones. Nicely done.

They still make phones with removable batteries? Who knew?

Well this one seemed quite removable....

/I keed

So are we saying if I get a Moto X I can open it up and replace the 2200 mah with the 3000 mah battery from the LG phones and they are compatible in both devices if I were to find a place that sells them as parts.

The only good phones are phones with removable batteries. Batteries are the most often thing to go wrong with a phone

I honestly used to feel the same way. Then I was given a Razr MAXX HD as a company phone about a year ago. With a handful of battery draining apps running ( 4 gmail accounts and one exchange account syncing, weatherbug, various social networking apps, about 30 minutes of gaming per day, and using Vire Launcher - one of the most graphically heavy launchers available) I still only charge my device every other night, usually at about 20% battery life. I can honestly say i've never once considered the need to replace my battery. By the time i feel i might need to i'm sure my contract will be up and i'll have the opportunity to replace the whole phone instead.

I used to only buy based off removable storage and removable battery (Droid, 2, 3, X, GNex etc) but this Razr has me converted. If OEMs put a large enough, reliable battery in their device, and stand behind it with a warranty, the need for removable batteries disappears. As for removable storage...well...that is a different debate for a different article.

The battery draining isn't really the problem for me. It seems like, with all my phones, the battery "dies" about one year in. Luckily, I only by phones with a removable battery, so all it takes is a quick trip to the cell store, $20 and I'm back up and running.

I also tend to keep my old devices after I upgrade. They're good for letting the kids play on or, in the case of my Evo3D, I still use it as a 3D camera for taking pictures of the kids.

I realize that this is me, and your usage patterns probably differ. And that's fine. But please quit telling me that my usage patterns are irrelevant because they don't match yours.

The Galaxy S 4 has a removable battery and is one of this year's flagships...

robnas says:

please use a little more depth of field in images like this. You can barely make out the curves and details...

all batteries are removable if you try hard enough ;).

It's the little things like this that I consider true innovation. Kudos to these companies for creating this little nugget of joy and then using them in their devices. Very very impressed by the G2 by the way.

And the apple lawsuit arrives in 3, 2, 1...

They patented shaped batteries a while ago.

intrepid359 says:

That's a dead link. And all batteries have shapes. You can't patent shapes and expect them to hold up in court. That's why so many of Apple's patents are being invalidated.

Apple would patent you grandmother if it wasn't for the Prior Art definition.

Lol this.

Zerolemon extended batteries are the same way, but with insane capacities and days between charges.

Yay, more buggy LG battery drivers.

Nexus 4 owner. No hate, just truth. Do your research please.

btgrave says:

Nexus 4 owner. No hate, but you are silly. I researched.

Man - to think that LG did not learn from this.... I mean you have used the LG G2 already right? So you know how the battery will work? Or you just basing this off your experience with a phone that is already over a year old?

intrepid359 says:

If you're going to make statements like that, present your own research.

HTC One should have used this exact 3,000 mAh battery, would have made the One truly mind blowing.

The One with Mid Blowing Redundancy

The One is mind blowing, mind blowing sense that over complicates Android by creating steps that don't even need to be there to access software Android ccould of done already in one step.

My Note 2's battery is still stronger.

I've had several extended batteries with this same design except much larger... How is this new or innovative?

I have one phone. I can run an 1850, 2100, or a 3800 battery with a hump. I prefer the hump, longer run time, and more to hold on to (it makes a nice little edge to grip). And when the battery won't hold a charge, I go to Shop Android and replace it.

Can your sealed phone give you those choices? (Don't reply, it's a rhetorical question and you'll look silly)

Li-ion batteries are only rated for 300-500 charge cycles. So for those of us that use a full charge per day that is a little over a year... my gNex battery will only go about half of its original battery life now. And I am going to need to replace my batteries (I have two that I swap out when needed) and I haven't even made two years yet.
