The trend towards integrated, non-removable batteries has caused much weeping and gnashing of teeth among the Android faithful, and nowhere is it more passionate than from the Nexus crowd. If you've been lamenting the Nexus 4's lack of a removable battery, ZeroLemon (purveyors of ridiculously huge extended batteries for major phones) has something they'd like you to see.


That's an external battery case, a form factor famous for turning svelte, short-lived iPhones into hulking bricks of longevity. The Nexus 4 doesn't fare much better. The ZeroLemon Juicer battery case makes the phone larger in every dimension adding 9 millimeters to its thickness, 12mm to its height, and 4mm to its width. For all that extra girth, you don't even get much of a battery boost compared to other ZeroLemon products: the case adds 2250mAh of juice, which should roughly double the Nexus 4's runtime off of the internal 2100mAh battery.

But the case has a trick up its sleeve, and it's one that we haven't seen from the likes of Mophie or PowerSkin (which don't have models for the Nexus 4 at all). The battery in the Juicer case is removable and swappable with a compatible ZeroLemon unit, giving your Nexus the removable battery you've always dreamed of. Kinda. You should be able to hot-swap the batteries without losing power to the phone, but unfortunately, the battery itself doesn't appear to be for sale at the moment. I suppose you could just buy two cases. It's got the usual cutouts for the camera and speaker, with a pass-through charger port.

The Juicer battery case is a reasonable $39.99 on Amazon, and comes in both black and white finishes. The listing shows the case as in stock, but unfortunately it's not eligible for Prime shipping. Any takers?

Update: Commenter Wayne Randall spotted this compatible extra battery plus a bodacious red charger, also on Amazon, and just $27.99.

    The Zero Lemon 9300mAh battery for my Note II is large, very large even, but this looks a lot bigger than it needs to be for 2200mAh.

    • Matthew Fry

      The case seems to be just a bit too small to fit two batteries on top of each other... Anyway, I feel they could reduce the height by using a microusb port with a ribbon (which if it doesn't exist, should).

    • Michael Pahl

      keep in mind it ADDS 2200 mah to the original battery.

      • hoosiercub88

        So 4350mAh? still.. seems way too big.

        • Michael Pahl

          thats the price of hot swappable.

  • aaron cooper

    Ummm, better have one of those big batteries like the ones I see above in the ads, 7000 to 9300 mAh.... then I will bite !

    Where did you get those dimensions from? I emailed ZeroLemon and they responded that the case is 1.5 cm thick, according to google that's 15 mm, or adding only about 6mm to thickness. Which isn't too bad.

    I ordered one, I plan on posting impressions over at xda when it arrives.

      From their website: http://www.zerolemon.com/details.php/zerolemon-nexus-4-juicer-battery-case-2250mah-removable-battery-pack

      Case Dimension:Length: 14.6cm / Width: 7.2cm / Thickness: 1.8cm
      Nexus 4 thickness is 9.1mm, so the case sticks out another 8.9mm (1.8cm - 9.1mm).

      Basically it will look like 2 stacked Nexus 4's. That doesn't look too appealing to me :)

      • Jeremiah Rice

        Yup, that's where I got them - they're not listed on the Amazon page.

    • ElfirBFG

      1.5cm according to Google is 15mm? Did you really have to Google that conversion?

      • Wayne Randall


        according to google, that means 'laugh out loud'

    Now if they could only cram a CDMA radio and antenna in there...

  • Nope

    Ugly as hell

  • Wololo7

    I wonder if it could be modified to have powered usb otg.

  • http://visionaforethought.wordpress.com/ Oflife

    Just don't understand the point really. Unless hiking, and in that case, you'll be away for way longer than even this case will be good for, we're surrounded by ways to charge our phones. 1) Car. 2) Desk charger. 3) Bedside charger. 4) Misc cafes, assuming one keeps a microUSB charger in one's bag. (I do.)

    • sivkai

      Don't forget wireless charger ;)

        Well, they should put a coil into that monstrosity.

        ikr I fracking hate it, but what I now do is charge my phone through my mac since I carry both everywhere. xD Works great....

        • CaibreGreyblade

          Worked for me with EEE PC too but don't tell me that even Air is less bulky then this.

  • Hal Motley

    Does it offer protection too? Then it would be a double deal!

    • Ror

      If by "protection" you mean ability to bludgeon an attacker to death with it's immense bulk, then yes.

    I want this. I want this for each and every phone without removable battery. Then, I want it for every other phone. And tablet.
    Best idea for someone who just needs that power on the go.
    They should cooperate with Otterbox or some other brand of solid cases and make ultimate outdoor ....thing.

  • SladeNoctis

    Sounds like a lot of people are showing hate on the design. Well at least somebody like Zerolemon took the chance to make a batttery case for the Nexus 4 and adding a option to hot swap the battery is a huge plus. Especially since the Nexus 4 has a hardly support in terms of accessories for battery cases. And while i had a Nexus 4, this is consider s Godsend for many users i met on XDA. The only gripe i have is that its a bit a late on its launch. Wish it was released closer to the launch of the Nexus 4.

  • Votlin

    Will you compare this case to the one sold by Mugen ( Mugen Power 4500mAh Battery Case for LG Nexus 4) ?
    Thanks :)

  • Peter

    Why the other "smarties" can use cases with 7300mAh capacity or more and nexus 4 Case have only 2250 ?! Is there any technical issues ?

    This needs to be retagged as "Nexus 4" not "Neus 4"

  • softboyled

    I've been using this for a few weeks and can report that it extends the n4 battery life by about 50%. That is, it will charge the n4 from 10 to 60%.

    There also seem to be a few quirks charging the phone from an external source through the sleeve when the sleeve is fully charged. Some times it just won't charge.

    Mostly it is a pretty painless affair in use. Just press the bottom button when you want a boost from the sleeve.
