Has anyone tried both the Mugen and Seidio extended battery covers?

I'm curious which one felt better in your hands while typing with the hardware keyboard. If Mugen does I will order the Seidio battery and Mugen cover independently as I've had good experiences with this combo of parts on my Palm Previously.

Dude man like really. Why wasting my time wit you. Everyone knows seidio rules. Just look at their website they have everything then look at mugenpower and like they don't have all the accessories, they are the low down dirty skanks of the cell world
Also with mugenpower better get a condom for your phone as they are made in dirty conditions with slave labor from china

I just got my Seidio 3300 and must say the case for it is extremely uncomfortable in my hands. There are way too many hard angles which is really taking away from the the experience of using the phone itself. I ordered the Mugen cover from the link posted below and will be updating this post in a few days when I receive it.

I like it. I think I'll order one. The decision to make it a thick version of the original seems perfect.

Yeah, especially with the keyboard fix TheImpaler posted last night. Although I have become accustomed to the Epic's weight I have always found it to be a little light for my taste. Even after logging some decent time in with this Seidio cover I still don't like it. There is just way too much going on in the back not to be distracted by it. Having extra meat in the back also makes typing 5x easier. I'm thinking a thicker OE design will be just what the doctor ordered. Mugen did a good job on their covers for the Pre and hopefully they'll do justice to the Epic's design as well.

I don't really use the slide keyboard. I just like the idea of the same/similar curvature as stock.

I just got the Mugen cover and its spectacular. I had to shave the living hell out of the insides to get it to fit as it uses a thicker plastic than the Seidio but it was well worth the effort. I highly recommend it. Feels great in my hands.

Nice. Can you post a picture of the insides?

Lots of scraping with a pocket knife lol. I lined the edges of the battery with some chalk to see what areas needed shaving.

Cool. Thanks for that. How does it fit around the edges? Is it precise?
I'm OCD and my generic eBay cover bugs the heck out of me because it doesn't follow the phone perfectly. Hah

It took about three days to come from Colorado to Berkeley. No shipping confirmation was sent so don't get worried if you don't hear anything from Mugen.

It fits great. I'm OC too and spent an extra 20 minutes shaving it down so that everything was nice and tight. I took off maybe 1/16" off when all was said and done. I'll post pics of it once I get home.

Thanks. I placed my order the other day. Do you still like it?

It was a little too much for me to be carrying around as a daily driver. I didn't mind it with my Pre but the Epic was just too big for my preference. I'm keeping it around for roadtrips however incase I need some intensive GPS usage. I ended up going back to the stock battery and lucked out when my phone bricked on Vision's 1.2 kernel. The sales rep at Sprint was nice and slipped me a spare battery. The girth of the extended battery cover definitely made typing a little easier so I ordered a protective case off ebay. Some guy is selling the same (supposedly) cases that Sprint sells for dirt cheap. They're the ones made by Otterbox. I picked it up for $7 shipped.

So for you it's a size issue, not fit or finish?

Yeah, fit and finish are perfectly fine. Expect to be shaving for a loong time. I think a pocketknife will work best.

I just received mine about an hour ago. Interestingly, the fit & finish is fine as you said but I had to put a spacer inside...not dig it out. I cut a business card in quarters, folded one of them in half then taped it inside.
I don't know if that's because of my batteries being eBay cheapies, or variance in the cover.
My only real complaint is how tight it is once it's on. Those little tabs make removal extremely difficult. Folks who never or rarely change batteries might consider that a good thing.

Same here, it seemed a little loose, and when I shut my KB to hard, the phone reset. Took me a while to trace it back to the loose battery, as I didnt notice it for the most part until I went to check my phone and it was off

Yah, I use my license to slip under and edge to get it off the back, but it sure is a PITA otherwise.
Overall, I LOVE it (once I fixed the looseness of the battery)
I really enjoy the way it feels when typing now, and I love the extra protection the camera lens now gets

Motorola Atrix 2 Extended Battery

Received my Motorola Extended Battery just now in the mail, draining it then will recharge fully to test it for full day tomorrow.
First impressions, it adds a little bulk, some protruding from the back. Replacement case has soft touch but doesnt feel as nice as regular back casing.

Hi guys! Can you tell me WHERE you ordered the extended battery? I've been trying to find it everywhere but no luck.
Can you point me in the right direction?

I ordered mine in-store at an at&t store, and got it shipped to my house.
I did order when it said "temporarily out of stock" (as it still does now, sku 40528 on att's site) but it took a couple days to get it sent out.
edit: fixed the sku, though googling for "sku5380297" will still find it faster (can't post a link yet)

Thanks for the info!

Hey Shanghei, have you seen increased battery life? Bimmerd00d isn't, was wondering if that's true for you too.

Moto Atrix 2 extended battery and case/cover
Hello,
I just bought this extended battery for the Atrix 2, and it is awesome!!!
it extends my battery life and I get a full day's charge out of the phone.
I was only getting less than a half day out of regular battery and had to charge it up after lunch... Although I am new to this phone and am trying/figuring things out so I may drain the battery faster than normal, and was considering not keeping the phone since the regular battery drained sooooo fast... But, with this new extended battery I think it is like 2700 mh battery, it makes this phone so nice.
It does not increase the size too much, but is noticeably heavier. I'm talking about the larger Motorola battery from their website or AT&T. I bought it from the AT&T store and am Glad I did... If you need more battery life then I recommend buying this extended battery - you will be glad you did...

I placed an order on the Motorola Store. They are shipping in 4-5 days. Will see how it goes!

Which Motorola store ? I keep popping onto the Motorola site and it still says coming soon. Battery life on the A2's been better then I expected, but I could certainly use more. I really want the battery so that the camera lens is a little more protected without having to get a bulky case.
Does the new back still feel as snug/solid as the original ?
Motorola support told me the phone should still fit with the car and HD docking stations with the extended battery pack. Any idea if this is true ?
& Thanks for the pictures.

The HD docking station has space for the extended battery pack. The car adapter supposedly has a removable "shell" to fit the extended battery.
It does fit pretty snugly, though the bottom part on mine sorta gives in and squeaks a little if you press it in below the settings/home buttons. I could probably put a layer of electrical tape under the battery door to make it feel more solid though it doesn't concern me.
As far as the Motorola store goes, it looks like it shows "coming soon" if you try to get to the battery listing from the atrix 2 page, but if you come at it from the batteries and chargers page, it shows it in stock.
Currently second on the list here and it allows me to add it to my cart.
Another option for those want an extended battery but not quite so extended, mugen power just released an extended battery for the bionic with 2000mAh instead of 1735mAh.
http://www.mugen-power-batteries.co...attery-for-verzion-motorola-droid-bionic.html
(bionic uses the same batteries as the atrix 2, since it's normal size you wouldn't need a battery cover)

Ran through a full charge on both now. It seems the extended and the standard reach 30% at the same time, but the extended one sits at 30% forever. Its simply a calibration thing at this point I think. It took 39hrs to kill the extended and 28 to kill the standard with my normal use
Sent from my Atrix 2.

I belive that if they could create a full bodied case with the extended battery built into it, I would jump on that. I refuse to walk out of the house without my case being attached to it. How do you people do it!!?? No case just walking around all naked and stuff.

I had my iphone 3gs for 2.5+ years with no case (just a vinyl back decal) and traded it in with it still in near perfect condition. I always keep my phone in my front pants pocket, screen towards my thigh (and I don't put change or keys in the same pocket). I only wipe the screen clean with a microfiber cloth, but otherwise, but a good deal of that time I was working as a mechanic, I'm not exactly dainty with my stuff. I tried a case, but they make it more difficult to pull the phone out of my pocket making for more awkward situations.
My only worry without the extended battery is that the camera lens is going to get scratched up every time I set it down.

What's the point in a case? Never had one, never broke/damaged/scratched a phone in 6 years.

Really? Is that even possible.? I am about the most OCD person I know with phone care and I HAVE to use a case. My favs are the Otterbox Commuter, Speck and some Casemates.
Have to say the extended battery looks like it adds a lot of bulk to the back. Will that really be necessary with the size of the battery in the A2?

Yeah, it doesn't have the softback texture does it? The positive thing I suppose is that it would keep the camera glass off of surfaces so you don't have to clean it off as often.

Powerskin Review, good pics, my charging solution.

Hey everyone
Just got my powerskin today, very happy with it! It's pretty much the only "juice pack" type of product available for the Sensation.
Here are some pictures:

The PowerSkin capacity is 1500mAh, inside of the phone I have the Anker 1900mAh, for a total capacity of 3400mAh!
Mugen 3600mAh extended battery $104.95!
My Solution
______________________
PowerSkin for $49.62 (direct from powerskin it's 59.99)
Anker battery for $8.99 free shipping
total cost $58.61
50% savings pretty much!
In terms of the case, you can obviously see it's as thick as a pack of cigarettes but that will only really tell smokers how thick it is lol, just trying to give you an idea. It's really smooth feeling so it slides in the pocket very easily. I also like the function that if I hold the button on the back for 2 seconds, It turns off the powerpack from charging the phone, I also didn't think it would show by LED light how much power the case had but it does, SWEET!
The fit is absolutely precise, although how well that fit will be maintained I cant say because I just got it, the material right at the edges feels a little "floppy" but that's not really a negative at this point. All in all hope the pics help, any other questions feel free to ask!
Enjoy!

thanks for posting this, although I'm turned off by the buldge on the side, I'm sure other uses will find this review very informative

I have a powerskin. It does a decent job. I won it in a contest though. Cost=free

I am growing to like it actually because the bulge with the divot allows my thumb to comfortably grip it

I picked one of these up for $30 with the T-Mobile 50% off coupon a while back. My complaint is that the micro USB connector doesn't have retention barbs. When I would put it in my pocket, sometimes the connector would come out just enough to break the connection between the skin and my phone and the skin would stop charging the phone. With that said, out comes in handy for leaving it charged and in my glove compartment for emergencies.

Not impressed. I bought this thing about a week after they were released & its already dead. It won't charge at all. It did stretch which caused the connection to get lost from time to time but not too bad. And laying it on the table sometimes pressed the button on the bottom to turn the case off

Daily I'd say I got an extra 5 or so hours. But the damn thing died already. I can't charge it at all anymore. Definitely won't be buying one of these for future phones.

I have and dont like it. It was a good use for a while then weeks later it gets wear out. Connection slips out of the phone so i gotta keep putting the connector back and its very annoying,....

...that's what she said.
(on topic) I had one of these for my MT4G and gave it up. It's just too bulky and I couldn't really justify the discomfort for the actual usage I needed from the phone. I found it easier with the S4G to just get the 2x1900mAh Anker Batteries+charger combo. I think I'll stick with that in the future vs buying the powerskin. My case gives me better protection anyway.

I used to have the PowerSkin... well... I still do have it, but it died in less than a week. Won't charge or anything. Just dead.

Otterbox + Extended Battery Case?

The phone is a lot heavier after, size wise, it turns it into Note 2 territory, just a little bit under it. (hence why the minute GN3 comes out, im ditching this piece of crap), but meanwhile will have to suffer.
The battery itself is just a doubled battery, but it adds just about 1.5 times the thickness to the phone.
I ordered 3 things.
Anker Extended Battery
Otterbox Defender Case
Extra Battery Cover
So first things first, mark out the where your going to cut, no point being all over the place. I just used a marker to color the battery and pressed the phone against the otterbox which left colored markings on the otterbox back cover where I needed to cut.
I used a hair fan to heat and soften both covers, then using a flat head screw driver made a series of dents along the cutting path to weaken the plastic. Then just cut the thing out using a small caring knife.
After the Otterbox hole was made, I fitted my 2nd back cover, then the otterbox and made an outline where the cutting had to be done. Made a series of dents and cut it out.
Also used a bit of sandpaper to get smoother edges and get the lines correct, but anyway. Its all done. Pics below

There is a tiny hump on the back, but compared to the stock battery cover that comes with all the extended batteries, but compared to the otterbox, its a lot more comfortable to hold and no one even knows, unless you point it out to them.

Ordered an Anker Extended battery from Amazon and going to pick the Otter box up on Tuesday and see can this work. Battery is about 5mm, whole case is just under 15mm. So by doing some DYI could fit.

I have the same things ordered and I am going to modify it as soon as I get my Verizon unit on Tuesday so I will have pictures soon. I did this to my note 2 which I am currently using and it works amazingly well and you can't tell it's even on there under the silicone. Hopefully the s4 is the same way. Even if there is a little more bulge, I am still gonna do it.

I did it to my Note 2 as well. Also using a Zerolemon 9300mah Battery. Talk about beast! Can't do anything to the S4. The wife won't let me haha..

Just remember the NFC chip for the S4 is in the battery so make sure your extended battery also has this or you wont be able to use NFC

Not really bothered about NFC as I haven't made use of the NFC tags yet, only couple of times I used it was to Beam a picture to my mother phone the odd time so no biggie, but it does have the NFC functionality.
For anyone interested THIS is what I've ordered. Its an Anker battery, had 4 of these bad boys in my GN2 and they performed excellently.
Tbh I doubt NFC will work great anyway with the Otter box as any time I tried using with a case on, it was fairly hard to get a connection between the two phones.
Galaxy Note 2's and Galaxy S4 + Note 2.
Hopefully Zero Lemon wont take that much longer and bring out a proper extended battery!

Here's my mod
I followed suit from the S3 and did the otterbox + extended battery mod. I just ordered an oem back from ebay.

Got my Anker extended battery. Have to say even though the hump is thicker than the phone itself, it's more comfortable to hold the phone. Got a nice big area to rest my right hand thumb on the side now, ads a bit of weight to the phone, but won't cry over it as it will save me of carrying around a charger with me.
Now to get an Otterbox on Saturday
Uploaded with ImageShack.us

i must say i had the same reaction with my old S3, when i bought the Hyperion Extended Battery + TPU Case....
the phone just feels better when its bigger like that.
nice brand, but im still going to wait for ZeroLemon

Finished my first day with the extended battery. 18 hours of battery life.
75% screen brightness
5 hours of screen on.
Media server half day
Data on half day, then WiFi when I got home
Couple of hours of spotify and some video
I'll be getting the zero lemon as well, but meanwhile. This will do

oh sorry didn't see much will reread to see what I need to do.

Anker battery you linked
The Anker battery you linked is not available off of Amazon in the USA. Has anyone bought one off of Amazon USA recently? There's no indication if it will be available anytime soon so I'd like to know if anyone has gotten one off Amazon in the USA.
So the Anker battery and case just snaps on easily onto the back of the Galaxy S4? And fits into the Otterbox defender without any modifications?
Thanks for all the information you've provided.

Best recommendation for Extended Battery?

What is the best extended battery out there right now for the Galaxy S4? I was offered a review sample for the Mugen Power 5500mAH model, and I will most likely take that. In terms of thickness, is the bulge noticeable? And what is a good extended battery that does not require a different cover or protective case? I currently am using a Spigen Slim Armor.

Considering this one:thumbup:

I have the onite 5200 with the Hyperion case. I would look at any of the 5200 ones since you can get the case and have some sort of minimal protection for your phone. On the onite I'll go 2 days straight easily

Just ordered the Hyperion 5200mah with the NFC...$23 on ebay + $9 for the case. Also ordered the Spigen Tempered Nano glass
OP, the Hyperion battery has great reviews and the case is comfortable to hold as well.

Personnaly i have Omega 7 (MF8) on my S4-i9505 and battery life is excellent (better than stock), and i use also Snapdragon BatteryGuru :good:

Zerolemon 7500mAh battery. Say what you want about how it seemingly makes the phone heavy, this battery just refuses to die.

At least my phone doesn't feel fragile with the battery in it.

Avoid. I asked them if their 7000 extended cell was really 7000. They told me it was "7000 peak" and otherwise 5500. That's nonsense. Maximum capacity is was it is. There is no "peak". Current can have peaks. Maximum capacity is a discrete value. These cells are backed by nonsense, and I would suggest avoiding them. Their "3500mAh" cell is likely under 2000 mAh based on my eBay cell instinct.

What is the best extended battery out there right now for the Galaxy S4? I was offered a review sample for the Mugen Power 5500mAH model, and I will most likely take that.

I have heard good things about the Mugen's quality, and adherence to claimed capacity. Potentially very over priced though, if they're still up above $50.

I think ZeroLemon has a 3000mah one. I have the 5200mah Hyperion Extended Battery.

I have the ZL 3000mAh cell, and the true cell capacity lives up to their claim (mine tested at 2890 on a discharge meter, which is within a fair margin of natural cell to cell variance as far as I'm concerned). If you don't need NFC, then this seems like a great option.

Recommend 6000mah Max Power Extended Battery For Samsung Galaxy S4 I9500, http://dx-box.com/6000mah-max-power-extended-battery-for-samsung-galaxy-s4-i9500.html

I have lots of experience with MaxPower cells across 4 HTC and Samsung phones. They've always tested poorly, typically holding 600mAh for every 1000mAh they claim (about 40% less capacity than advertised). Expect that cell you linked to to hold around 3600 mAh, and definitely not more than 4000 mAh.

I have a hyperion 5200
And love it I get a good day from 6am to 6pm I still at 65% with average use

I have read good things about seido and hyperion, but I've never tested one of their cells.
I've tested many iterations of Anker cells, and they've always met their claimed capacity. There's also a brand called EXOpower that I just tested for the S4, and they lived up to claimed capacity, but their NFC circuit doesn't actually work in the S4, despite claims otherwise.
Here's the bottom line:
If you're not going with a brand that has an established reputation for actually matching claimed capacity figures, then the capacity figure is basically just made up. It's irrelevant whether a cell claims 2600, 3000, 3500, etc. If they're all from unknown brands, then those figures mean nothing, and they're not even useful for comparison relative to each other. The claimed figures are truly meaningless.

What are the parameters of the discharge device? The cutoff voltage is an issue with these devices since most of the time they differ greatly from their actual use limit. What did the meter say about the stock battery?
