Hands-on with Seidio’s 3800mAh Extended Battery for Galaxy Nexus [Contest Too] (Updated: Winner Picked)

No that is not a military vehicle on your screen, that is the Samsung Galaxy Nexus with a Seidio 3800mAh extended battery attached to it. It might look like a tank, but it will certainly power your phone through a full day thanks to more than double the juice of a standard G-Nex battery which weighs in at 1850mAh. I picked one of these up (the NFC version of course), to see how big it really was in person, but also to give one away since they pack a $75 price tag. Before we reward one of our amazing DL community members though, let us talk about it for a moment so that others can decide if their pocket can handle one. 

So how big is it? In the comparison shots below, you can see that the thickness matches up almost perfectly to a G-Nex extended (2100mAh) and standard battery stacked on top of each other. It’s thick, people. It adds a decent amount of weight, meaning you will notice a difference. It also has a purely black cover which of course does not match up to the coloring of the actual phone. So not only does this beast stick out a half an inch or so off the back of the device, but it stands out in looks as well.

What about a single life charge? I’m not going to lie, slapping this on the back of my phone would be the equivalent to someone scratching fingernails across a chalk board. I’m a minimal phone elitist, meaning I love my phones thin and sleek and without massive, non-matching humps on the back. Basically I’m saying that I have not fully tested this battery, however, at 3800mAh this thing includes more power than the 3300mAh battery tucked into the DROID RAZR MAXX which can last you anywhere from 2 to 3 days. This battery should easily hit numbers like that. The big thing here is that this battery is not slender like the RAZR MAXX’s. If you are interested, you have to ask yourself if the added weight, thickness, and black non-matching back are worth it to you. For some, the answer is a definitive, “Yes.”

Other notes? The new back plate has a soft, almost matte black finish and feels a lot like the new Ringke SLIM case that I reviewed last week. It doesn’t feel that bad in hand and is essentially slip resistant. This version of Seidio’s battery is also the NFC-capable one, so you won’t miss out on any Google Wallet opportunities with this attached.


Since I sit at a desk all day long blogging away with a chargers are arm’s reach, a beastly battery like this is not necessarily topping my list of must-have accessory. So we thought we would save one of you $75 and give it away. Sound like a plan?

To enter:

1.  Follow us on Twitter if you aren’t already.
2.  In the comments, tell us how badly you need this extended battery.
3.  Tomorrow at 9AM, we will choose a winner from the comments.

Good luck!

Update:  Our winner has been picked!  HuskerDroid10 was randomly chosen and will take home the NFC capable, 3800mAh Seidio battery for the Galaxy Nexus. He hopes that this tank will get him through sporting events, something his current battery cannot do.

  • I live an hour away from my fiancee, and she loves sending pictures (you know, of puppies and kittens and other things that men like), so more battery means more hotness, err cuteness!

    As a Police Officer I am always using my phone at work. I currently carry a standard battery, an extended battery and a car charger with me everywhere I go in an effort to keep my phone alive. I use my phones camera to do quick snapshots of suspects and such. I pull info from the web on the fly and look up drivers license photos of people in the field and use the wifi hotspot to get data on my laptop. A large battery like this might be what I need.

  • I need this so badly! I just picked up a second job landscaping that will have me working a 6am – 2pm shift then a 4-9 shift every night. I need a battery that will last through all of that THEN a few more hours while im in the library studying for my computer engineering major at OSU. Please I need this! 

  • TravisHannon

    I need it to last during music festivals! bogged down 4G and 3G kills battery life! #firstworldproblems

  • Ulnek75

    wow. i’d like one. on weekdays i’m at school from 8 to about 7 then work after.  i have some text books in my phone and i use it to do homework in between classes.  with the screen being on all the time, i go through the battery pretty quickly and i have to switch batteries.  sometimes i forget to charge and i’m out of luck.  it would be great to get through my day without having to switch batteries .

  • Cgriffith0012

    Hmmmmmm…..because I’m better than everyone else?

  • I am actually very sick and tired of battery life on my Android phones. I am getting to the point that I am actually considering going to the Motorola Razr Maxx! As much as I hate a locked bootloader, I hate a dead phone even worse. I am always on the go and do not have time to be charging my phone in a pit stop fashion. 

    So Droid-life, hook a brotha up! 

  • Claytonhoppe

    i need this battery because the stock is just not cutting it.

  • RWW

    Sure, it’s gawd-awful ugly..  but some times you’re out in the woods and need your Nexus to last more than  13 hrs, right?


      Ned Beatty wishes he had this accessory if he did he might not have had to squeal like a pig. 

  • i <3 tanks

    I should win because I never win anything on here so why not win this gynormous tank accessory!


    when my wife asks me “am I fat” i hold up the profile of my phone if it obscures her shes not fat and i tell her so…. I NEED THE BATTERY!


    I dont always want to look like Quasimodo but when i do i sport my G-nex with the 
    Sedio 3800mAh battery.

  • Russellneal88

    I travel too much to be by an AC charger very often. I’d use this 🙂


    I need this because while i am married the hot mommies at the playground will not leave me alone. the sight of me playing WWF with my totally sexy phone must make them gush. Time to end it now!

  • Shadow18z

    Because carrying two batteries with me is pretty silly.

  • Brianusn07

    I need an extended battery because i simply never won anything through droid life yet. and this would  be a good way to start my contest winning streak. 🙂

  • As a government employee, Army reservist and student. I am constantly on the go so keeping my G-nex charged all the time is quite a challenge. This battery would be wicked useful for me.

  • Gene Sok Yun

    I can barely make it to lunch without draining my battery.  My job requires me to be online and on the phone constantly,  You have to understand, I NEED THIS BATTERY!!!

  • Cmonnats23

    I need the super extendo battery so I can surf the web for a full 24 hours and not have to worry about having enough power to last me the whole day!

  • Nick Petrefski

    Everytime I leave the house for longer than 3 hrs my battery is red!

  • it would be nice when im tethering to have that extra umph

  • I don’t need this extended battery, but I sure would like it.

  • twix_y

    I’ve always wanted more junk in my nexus trunk

  • Everyday, I go to my college classes and then work (at the school) for 6-8 hours after. On average, I’m at school for 11 hours a day. Because I use my phone for everything, the normal battery just doesn’t cut it. I need an extended battery just to make it through my long days!

  • How badly do I need the Seidio extended battery?  VERY VERY VERY BADLY. Really; very badly.

  • Adam Cargal

    Most of the time I’m not too far from a charger, but sometimes I work away from my desk.  Having this battery on days like that would be amazing!

  • froader

    I can’t even play a round of golf using GPS on the gnex. This extended battery should do the trick!

  • I work 13 hour days at my job, and my phone last maybe half of that.  I can’t do anything about it tho because there’s nowhere I can charge it.  I’d love to have this thing to try and stay connected!

  • I need this like Mark Sanchez needs a trust circle.  Your good enough, your consistent enough, and dogonit people like you!!!

  • GazaIan

    I need this, I can’t tell you how many times I’ve underestimated the weight of the Nexus… I lift it and it goes flying because it’s so light…

  • Craig LeBaron

    I NEED this so that I don’t have to explain why I’m always charging my phone at work. No, of course I’m not on it all day. I just forget to charge it at home… Every day… Yeahrightthatsit.

  • Kal5el

    I’m a college student and my extended battery can’t make it through classes. I need this battery!

  • Tony g

    The sedio battery is overpriced. Hyperion has a 3800mah for 20$. Comes with nfc.

  • I work twelve hour shift over night and the extra juice would come in handy.

  • Mayze23

    I need it because I have 5 kids that want to play my Gnex all the time!

  • I could def use it cause I am constantly using my GNex.. whether it be for games or surfing my battery doesn’t last a full day without needing to be charged! hook it up droid-life!

  • zachjen

    with my work I am never around a charger so I’m always fiddling the settings trying to get ever ounce of juice out of my battery. This would solve that problem.

  • HowDoIShotWeb

    I need 3800 mAh on board because, well, I’m an addict. That and I’d like to poke a Razr Maxx user or two.

  • jon

    So I won’t leave a meeting in the middle of the day and then find out that my battery sucked up 20% even with the screen off!

  • Standard battery is not much enough to use all day.

  • kikit

    I would very much love to have this, I have been wanting to pick one up for a while but haven’t had any money to do so, its just more than I have right now, unfortunately my job doesnt pay me enough to get things that I would like to have.  I could definately use this too since I am away from a charger all day long and my battery for my Gnex now dies super fast since I use it for voice calls mostly.  Please pick me.

  • GuidZilla

    Need one for when i’m bored waiting for Turkey to show up to my blind… 3g in BFE helps pass the day 🙂

  • real4life72

    I ride my motorcycle alot and even tho this battery added to my phone may make my bike drag the road a bit it sure would be great on long trips with no charger.

  • Tim Buchanan

    How does it compare to the $7.00 one you had posted on here the other day?  Cuz…I bought that one.

  • Tsabhira

    SO BADLY. I love this phone, I do, but the battery drains away in just a few hours of games and general screwing around. I’d be willing to put up with the ugly to make it last longer.

  • Soapinmouth

    i neeeeed it i use my phone for work related features and the horrid reception always kills it there

  • Chris

    I so don’t want it, but I do need it.   I wish it wasn’t so huge, but even my 2100 battery isn’t cutting it. So if you could so kindly help a fellow geek out.  I’d walk your dogs for ya.  🙂

  • Rauldom333

    I would like it because I can’t even afford the $25 Verizon battery. 🙁

  • I need this so I won’t die every time my phone does.
