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 bought my Galaxy Nexus with a second battery, because the Verizon store I went to was out of the extended(go figure). I go part way through my normal day with one battery, and switch the battery out at my halfway point. Not even using 4G, I have it set to 3G to save battery(ha!). Would appreciate this giant battery, even though I know it wouldn’t fit in my otterbox case.

  • Why I need this battery so badly:

    Because Verizon’s Extended Battery is far too contained.

  • Adartilth

    A full charge for me only lasts 2 and a half hours on the samsung extended battery =/

  • I so need this, just can’t get through an entire day on a full charge!

  • I have to charge my phone everyday at work to be able to make it through the day.

  • @droid_vans_life

    I wake up go to school then go straight to work. Ask me if my phone makes it past the train ride to work. Let me answer that no it does not. No phone at work is like me trying to flash a ROM and md5 sums dont match. So annoying :p

  • Black78heart

    Extra juice please. Hold the ice.

  • I’ll keep it nice and simple.

    I travel from Arizona to Mexico quite a bit where coverage is very bad and my battery never lasts me more than a few hours. I also go on off-road trips and this extended battery would be a life saver.

  • ManBearPig618

    I need it. Badly.

  • Derek Britton

    I am gone for long weekends all of the time and it would be great if I didnt need a charger everywhere I went

  • znewman

    During my normal day of work my phone dies at least once due to heavy use.  With this I might actually make it through a day.

  • I have to keep my phone on the charger throughout the day.  That’s how bad I need this.

  • Angel Calderon

    Im sorry but if my phone looked like this with a battery i would most likely never bring it out of pocket, what am i saying, this thing wont fit in my pocked, i would need a book bag to hide it. And forget about flying with it. The FBI might think is a weapon of mass destruction. You must be deeply in love with this phone to not see that it looks more than bad, so bad that i would rather have “the fruit phone” strapped to my forehead.

  • Darren

    Need one! Am away from my desk ask day.

  • Andrew

    So badly

  • Josh Groff

    I need this as an excuse to buy a Nexus. Otherwise, RAZR MAXX wins.

  • Sp4rxx

    more juice or not, that battery makes the nexus look as ugly as sin…. bye bye sleekness – hello brick!

  • thedanks

    This battery would really help me.  The building i work at has really bad verizon and wifi reception… it has a lot of insulation and its just in a dead verizon area.  My phone is always searching for different signals and this would really save me a lot of headaches.  Thanks for the chance!

  • I need the extended battery because I basically carry around a generator to keep this thing charged when I’m not near a plug…kills the battery so fast!

  • Kevin Smith

    I could use this pretty badly… I was at a bachelor party in Atlantic City this past weekend and had to constantly run up to the hotel room to charge my phone for a few minutes. Talk about ruining the party.

  • supra_2nr

    Would love this for my gnex!   I was looking at buying one but id rather not!

  • Don23lucia

    I need this thing between work, college, 3 kids, soccer, football, ballet, and karate. I need something to keep my phone going cause right now it dies before my day really starts!


  • Matt Ponkey

    Humpback or not, I need 2 to 3 days without a charge for when I’m on the road.

  • This battery would help me sooo much.
    Im sick of having a charger in every room.
    I want my nexus to be free, even if it is with a tank on the back!

  • Caveman418

    I am traveling from workstation to workstation from 6:00AM till 4:30PM everyday. I do not have time to stop and let my phone charge or leave it behind because it is the only way for my family to get in touch with me. As it stands now, I have to turn everything off on my phone that is absolutely unnecessary (GPS, Bluetooth, wifi, screen brightness) and only manually check my email to keep my battery lasting as long as possible.

  • Eddie

    With no wifi at work, my battery is dead by 3pm unless i have time to charge it. I need an extended battery!

  • droidify

    This would be a perfect compliment to my fanny pack.
