[MINI Review] OEM Moto Extended Battery 1930mAh

Well I decided to go pick up a Original 1930 mAh DROID X Motorola Extended battery. I USE my phones to the hilt, I sync everything, use everything, and take full advantage of all the features like you should when you have a device like these. All in all I am not a battery scrimper, I have a charger at home, one in the car, and a USB hanging out of my laptop everywhere. LOL. I have always hated the Tumor that sticks off the phone when you are using a EB's, but since you can barely Moto's EB is even in the phone I thought I would give it a shot.
Now to make this to the point..... When I put the battery in new it was at 30% I ran it down to the 5% warning and red blinking light. After a full charge from the Wall charger (Which only took 2 Hours BTW) I pulled it off and ran it "business as usual"... Calls (About 2 hour 20 mins worth), Browsing, Chat, Pics, Texts, Apps, Wifi on, Downloads, Played Rock band for awhile, Full sync to all 5 Gmail accounts, FaceBook every hour and Twitter the same. Plus a 1300mHz OC (Low Voltage) with out Screen off or battery low profiles (I thought that would be unfair). Here are the findings....
Total Time Unplugged: 14 Hours 34 Minutes
My setup is in my Sig but... basicly it is Rooted, I stripped ALL Bloat from the Stock ROM, and like I said before Droid OC to 1300 (Low Voltage), Also... GoTo Lockscreen
So now.... I can leave my chargers at home and plug in once overnight. I have to say, this is the best $50 to spend on the phone.
NOTE: This was only after the FIRST charge, after 3 complete charges I can only assume it will be better.
EDIT>>> For a comparison... Running the stock battery I would be at 20-30% by 12:00 (Noon) Easily

I'm with you on that. The fact that it adds barely anymore thickness to the actual phone and the amount of power you gain from it made it an easy purchase for me.

Yep, I believe it is 1mm... Which is nothing. And actually, the device feels a less top heavy and it fits in my hands quite nicely now.

One thing that is concerning to me is why does the first screen show your battery at 33oC? Were you charging at that time, though the icon doesn't seem to show that. I hardly get 28oC at 1.3ghz stress test while charging.

I did notice my temp did go up after installing the EB... The screens where taken at the 5% warning.
As I said, that was the first run of the battery. Now after the second full charge I have been steady at 29c. Maybe a conditioning or burn of the battery?? Can't really say.

I have this battery too, and I use the standard battery door with it. It is a little snug, but it does fit. This avoids any excess bulk. I have used it this way for a few months now. I am running apex and overclocked to 1.3 and my battery life is great.

I've had this battery for quite a while now and I've found my battery dying A LOT faster than it used to haha. When I first got the battery, it was amazing, now.... not so much haha. Been doing charge cycles and clearing battery stats but it still remains bad haha. Still much better than the stock battery though haha.

ive always been tempted to get the extended battery and today i finally purchased it. Your review definitely helped get me to do the obvious and purchase one

Verizon and Motorola should give you a commission!
Due to your review, I went back to the Verizon store and bought the battery. Heck, the salesperson never told me that they even had this available, or I would have bought it with the phone!
I'm running it in an Otterbox Defender case, with the battery cover that came with the battery. So far no issues, but I'm getting much better battery life.
Thanks!

I'm going to the VZW store today to get this battery, thanks for your great review!

Hey, I have an Otterbox Defender and I have been holding off on picking up one of these batteries. I really want the extended battery but I don't know how it would work with the case.
So the battery does come with an extra back plate for it? Have you tried the battery on it's own without a back plate and just using the Otterbox case and if so, how does it fair?

me too! just got it today!

The battery comes with its own battery cover. It didn't feel thinner, but a bit heavier. I'm guessing it's a heatsink.
I put the battery in, put the cover on, and put the Otterbox case on. It was a tighter fit, I had to be a little careful in ensuring that the two halves of the otterbox case locked together. But it's together and I didn't have to modify anything. I've been using it ever since, and haven't had any problems. And I *love* the extra battery life! I routinely have 40% left at the end of the day, and I'm a pretty avid user. I have an Exchange account on push, gmail on push, and use google voice constantly.

Hyperion Extended Battery

Ordered this a few days ago and it came in the mail today, it says for the i9300 (international) but I took the chance and it works great for my AT&T version.
http://www.amazon.com/gp/product/B008BVIV06/ref=oh_details_o01_s00_i00
It's a Hyperion 4000mAh extended battery. Its about the double the thickness of the stock battery and has a new back cover to come with it. On the card included with it, it suggested a 12 hour initial charge and then 4-5 cycles to reach full potential. I will be following up on the thread periodically over the next few days with some screenshots and other thoughts on how the battery is working out for me.
However, initial impressions are good. The back cover is good quality, however very slick compared to the stock one. The thickness with the added battery isn't terrible, and will definitely be worth it if it doubles the battery life like it should.

On the amazon site it looks enormously thick, like a half of an inch or so, can you measure it for exact thickness please?

5/8" thick total. Like I said, it makes it quite a bit thicker but double the juice... You gotta put it somewhere lol. At least it looks a lot better than the Note extended batteries did, those looked atrocious. There was just a bump where the battery was but behind the camera was stock thickness and it looked horrid.

Does the battery have the NFC antenna?

No nfc and bulky on a rather sleek n sexy phone...no go here. Plus the battery life on this thing is SICKKK, why the need for the extended batt? I could reason with an extra battery.

Well to add to my review, the back panel breaks VERY easy. My phone took a 2 ft tumble off my bed and it took a chunk out of the battery panel that came with the extended battery.

I was thinking of either getting an extra battery it just buy one of those battery packs that recharges the phone. Friend has one of the Energizer packs for his iPhone and it appears to work really good, that he bought an extra one.

Unfortunately, $6 shipping.
Looks nice though with an equivalent storage of approximately 2000mAh with 4 NiMH's in it @ 5v or 10Wh (minus whatever conversion losses, probably about 10% so 9Wh). Original battery is about 7.8Wh capacity.

if you want a good external battery pack goto amazon. serach for vaas battery. get the $28.99 shipped one with the 2.1 amp output
sadly its mini usb not micro to charge but at least its STANDARD and not proprietary. it charges up my S3 just fine should be able to get 2 full charges out of it or run the phone for DAYS if you use it while the phone it already fully charged.
it is by far the best battery pack I have purchased yet I would not by anything else.
they have a cheaper one. SAME battery but less amps on the output. if you buy 2 to avoid shipping its under $16 a pop ($15.70 each) but I am not sure if it has enough power to charge. I know the 1amp outlet on my unit does NOT properly charge my S2/S3 (trickle charge) I have to use the 2.1 amp outlet.

Stock charger for the S3 is 700mA so a 1A charger should be more than enough. Some dual port chargers list 1A but limit each port to 500mA. I sometimes wonder if using higher capacity chargers (I've been using some HP Touchpad 2A chargers) might have thermal issues shortening battery life. But, I like the quick charge.

my stock s3 charger is 1A ??
there is "port" differences. I have a VAAS battery pack I use (6 of them I power a lot of stuff) and the 2.1 amp port charges the S3 fine but the 1A port is "slow" (trickle??)

Anyone having problems with this? Fit, finish and signal?
I just got the Hyperion Extended battery with the dark colored back. I also got their case to fit it.
All was well when I put the new battery in and covered it up with the new back cover. I then installed the case and left it to charge. That took about 3 hours to go from 58 to 100.
When I picked up the phone, I noted that there was no telephone signal (at home it was on wifi). I checked the settings (not in airplane mode) and then turned it on and off again and it was still no telephone signal. So, I took the case off, put the old battery back in and all was OK. I switched back and the signal is now good.
I noticed that the back cover was dirty. I thought I had gotten some kind of smudge on it so I wiped it off. The smudge just got bigger. The cheap coating of paint was coming off.
Earlier, I had noted that the charger plug didn't feel quite right. When I looked closer, I saw that the small top part of the opening for the plug didn't quite fit. We're talking a millimeter or so, but it doesn't quite fit. It is so thin that I cannot consider cutting it.
My first inclination is thinking that Hyperion is junk. Since I have been considering getting a new, bigger battery almost since I got the phone a couple of months ago, I don't want to give up.
So, what are your experiences with this company's products? If I send any part back, I have to send it all back. The battery came with the big cover so if I send back the cover, the battery goes with it. If I send those back, I don't need the case.
Where do I go from here?

I just bought the Hyperion as well. So far, so good. I did get the Hyperion case as well. The power and cooling buttons are really hard to push. Can anyone suggest another case that will fit the Hyperion?

No issues with mine so far. No signal issues like other member mentioned. The back cover fits very well. Charger plugs up with no problems.

Review of Yoobao Thunder 13000 mAh external battery w/pics!!!

This is a review of genuine Yoobao Thunder 13000 mAh external battery: http://www.kevikev.com/Yoobao-Thunder-13000mah-Power-Bank-for-USB-Mobile-Devices-YBTHUNDER13000.htm
With so many reviews behind my belt, this is a first time I'm specifically referring to a product as "genuine". Here is a reason why. Yoobao is a popular Chinese manufacturer specializing in cases and batteries, but it's not that well known in the States because there are only 2 US dealers with www.kevikev.com being the only one verified by Yoobao (I actually checked that on Yoobao website). I came across HK products that look identical to these, but was informed by their sellers those weren't real Yoobao, only lookalike. That obviously turned me away, until I got an opportunity to review the real Yoobao product with samples provided to me directly from kevikev online store.
External batteries continue to push their capacity while maintaining small footprint. This Thunder model goes all the way up to 13000 mAh with a dimensions of approximately 136 mm x 74 mm x 28 mm. Higher capacity also means more battery cells and increased weight, which in case of Thunder is about 300g. I wouldn't call it pocket friendly, but you have to trust me - this is a kind of battery you want everybody to see due to how cool it looks! Personally, I wouldn't even call it Thunder but rather something like Ninja Warrior! That's how it looks to me It has a very solid hard plastic material on the top and the bottom and two end sides, while around the grip sides it has a red rubber material stamped with snow flake pattern. The power/control button is in a shape of a warrior mask where the eye light up blue/red depending on it's charging cycle. Also, there are 5 hidden light elements around it to indicate charging capacity of the battery partitioned in 20% increments. This battery has 3 ports, one micro-usb battery charging input, and two full size usb device charging outputs. In addition, it comes with a very bright torch LED light. A very nice bonus if you are in the dark (like during power loss) and need an extra light source which can last you over 500 hours at full battery charge, or just a way to light up usb ports so you can connect your smart phone or tablet. Along with Thunder battery, you get a high quality usb to micro-usb cable. I actually like the rubbery texture of that cable, it has a premium feel to it. Also you get Apple 30-pin adapter, and to my surprise a premium quality wall charger rated at 1A. This way you can use a wall charger with included cable to charge up the battery, and then use the same cable to charge up your device. This external battery came already pre-charged to about 80%, and when I was charging it up to 100% I felt wall charger getting a little warm, but nothing to be alarmed.
Even so this external battery looks very cool, it doesn't matter if it can't deliver. So here is what I found while putting it through my test. Since it already came pre-charged, I didn't have a chance to time a total charge up time. But since input is rated at 1A, we are talking about 12-13hr from empty due to its 13000 mAh capacity. The manual which comes with a battery mentions that Output 1 is rated at 1A while output 2 is rated at 1.5A. From my test I was able to to confirm that both outputs provide 1.6A of charging current which is what I typically see from most of the 2A wall chargers. This is a very good indicator that you can charger your Note 2 fast from either of the ports and don't have to worry if you are plugged into Output 1 or Output 2. For my test I actually had my N2 with ZL9k3 battery down to single % digits, and let it charge overnight. Yes, the rated capacity is 13000 mAh but the actual capacity available to phone/table battery will be less due to efficiency loss of conversion through 5V usb port. That is a know fact and common to every single external battery. According to my calculation of charging time and N2 battery percentage change I determined the actual capacity of Thunder to be around 8800-9000 mAh, which is very good and on par with 30-35% efficiency loss expected from these high capacity external batteries. This is a very impressive number considering you can fully charge your Zerolemon battery with Thunder or charge your N2 almost 3 times with stock battery.
Overall, this is one Awesome battery in terms of looks and performance!!! It's not your usual rectangular brick you keep for emergency out of sight. Thunder is something you would want to keep on your desk as a center piece to show off. And the cool looks are backed by a solid built and a great performance of high capacity and fast charging of your device. What is more important, you are dealing with an authorized Yoobao US dealer who will honor its 6-month warranty and can service/replace the product if you need to. This one gets my recommendation!
Also, I want to mention that I'm working on getting you guys an exclusive 10% off coupon for purchase of this battery... Here you go, hot off the press: the coupon code is kk001. It should work with this battery or any other purchase total of $50.
Here are some pictures for your enjoyment. I tried to take the last few in the dark so you can see LEDs better:

You mean Anker E4 13000 mAh? Very good point. They are identical in spec, even with torch led light Anker is a few dollars cheaper (considering 10% discount you can get with Thunder), and you get longer warranty with Anker. But from visual perspective - Thunder is in a class of it's own. It's not a regular rectangular box, but rather a gadget with personality. The way how it's shaped, the quality of the case material and side grips, that warrior-mask power button with eyes that light up (either blue or red) and shapes of the little indicator lights around it - the Cool factor adds to it's value. Just my opinion, and please don't hate me if I persuade you to buy yet another gadget you weren't even planning to get

Lol. No hate here and you absolutely right, tunder looks very sexy and appealing.
Now I just need to find an excuse why I need it , which won't be an easy.... since I'm rocking ZL, which is powerfull beast on its own

I've been looking for an excuse to practice drawing prints off of batteries!

I'm selling this in Asia and i must say it's very popular. It's sold out the moment i gotten new stocks.

Max 1.5A seems to be a little slow at charging. Dig the design though.

I confirmed both ports charging at 1.6A, exactly the same as my oem Samsung 2A wall charger. So you are guaranteed to charge it as fast as from a wall charger.

Hey Fellas,
I am a part of Ankers Power User Program and will be reviewing /testing this product for them. I will provide dimensions, runtimes, heavy usage, real-world usage, ect.
Additionally, I will run a side by side comparison using same phone/ same tests. I just ordered my ZL 7000, now that it is in stock again.
****DISCLAIMER****
I was supplied a sample for test and evaluation, and promised that my review would be fair and honest.
Here are some stock pics.

WOOOW. As soon as I ordered my zerolemon and it already shipped out. This looks like it has a much more beautifully designed case and much thinner! I might as well order given the extra 200mah
Did this literally release today? I went through my whole weekend researching different extended batteries and debated myself which one I should get. Thickness is my biggest concern with the lemon
edit: it seems the dimensions are basically the same. But i may still go with this as it looks 10x better than the tpu case from zerolemon

wow... this is really thinner than my zerolemon case....and 7200mAh...
off to amazon.com! to get me one

The lack of nfc is a little disappointing, but it's so big! I'll probably pick one up since the zero lemon disappeared.

I believe this released for sale on Amazon Sunday night 12/15

This case looks amazing compared to my zerolemon one.. but I still love my zerolemon case.

Ordered it yesterday and get it today, let you guys know how it turns out. got it because zero lemon disappeared so hopefully this one turns out good!

Do you guys think the Laza Samsung Galaxy S3 RuggedFusion Protective Case for Extended Battery or any other quality protective case would fit with this battery? Or will the TPU case that it comes with be enough protection?

I got one as well as part of the poweruser group. I'm just received it today and will be posting some pix in a couple minutes

I am not sure any other case will fit. I looked at the zero lemon otterbox like case and the anker has some sort of a raised plaque on the outside that I don't think would be compatible. I put some pictures in my thread if you are interested.

If you are on Verizon go ask for an nfc sim for isis. I got one in January, and so far $25 free from whoever had their prepaid option before and I think they have a new promotion with Amex serve for 20%cash back plus nfc even with this battery.

I Just orderes waiting to come. i will write my experience

Hows the fit of the case over the phone and battery?

its really nice. i have pix in my thread if you are interested. seems like a durable and safe case for the phone

First Impressions......
The Anker 7200 is very well packaged, and the amount of thought that went into it really shows. The box is high quality and branded accordingly. The battery and case are enclosed in a plastic sleeve, then placed into a form fitted plastic tray with lid. Instruction manual, warranty card and power user info included.
Sent from my SCH-I535 using Tapatalk

The case......
The case fits battery and phone nicely. The fit is snug, but not ridiculously hard to attach like some tpu cases. It is also the smallest and thinnest of the cases I have used. Compared to the Trident and Otterbox, it is the smallest /thinnest. The TPU material is rigid, and would seem to offer good drop protection. In comparison to the Otterbox TPU, the Anker TPU feels more durable, and likely to be penetrated by sharp objects during a fall.
The buttons are responsive and easily identified. The finish of the case is nice, the back being glossy and smooth-matched by a matte border to facilitate grip. The case feels good in the hand and surprisingly not slippery-due to matte case border.
I personally like the look of the case, but the shiny back is prone to smudges and fingerprints. While it makes it easy to slide in and out of your pocket, Im sure that I will be constantly wiping it down ( I'm a bit neurotic like that ).
I currently run the otterbox modded with the Anker 4400. I use this primarily because I need a holster M-F. However, I can see myself using this Anker case on the weekends- sliding nicely into my back pocket.
Suggestion......
It would be nice to see a holster/case option for this battery similar to Zero Lemon.
Perhaps a matte option with knurled edges?
The battery......
The battery is very impressive to look at, not only the size of it, but Anker also added an a rather thick acrylic plaque for branding / or spacing purposes / protection? Whichever purpose it is supposed to serve, it does look nice.
The battery arrived at 50% and I put it on to charge 100% before use.
The battery and phone assembled is about the same size as the ZL7000.

While they both appear to look the same, and have the same outputs:
USB Output: 5.0v 1000mA
Charger Dock Output: 4.2v 600mA
The Anker charger would not fully charge the battery-max88%. I completed the charge with the ZL ext. Charger.
I discharged and recharged for 1 cycle. It took 11hrs 50 mins to recharge on the ext. Charger. It will obviously charge faster on USB -1000ma. Vs 600ma-and I will post the USB charge time once acquired.
The battery was drained using juice offender / and gps test.
Screen brightness set to 100%
Wi-fi, Blue Tooth and GPS all on.
This battery is amazing. The phone was on continuously for 17hrs 10 minutes, with a screen time 8hrs 23 minutes! I played games, browsed the web, played music, made calls, sent emails all the while!
I'm going to discharge one more time under normal real world usage.
Auto dim, Wi fi when at home, bt in car, and normal emails games and music.
I will perform one more rapid drain, using the same apps and usage for final comparison.
My understanding about batteries of this size is that they need to be cycled a couple times for cells to normalize.
Its easy to see that there is some kind of voltage fluctuation in this battery. At 85% the battery had a 2% variance and at 65% a 1 % variance.
I have to say, I am very pleased with the results thus far, and am curious as to how it will perform under normalized conditions.
Stay tuned!
FYI- As of this update, 1.2.2014 the battery is on sale for $31.99 Amazon.

indeed it looks big. by mistake, does the zerolemon battery focus on the same performance? 7200 or something similar?

Stay tuned.

I was in the market for a large capacity power bank and really liked the look of this one on Amazon. Shipping was very fast as it was fulfilled and shipped by Amazon. In this review i will go over the Features, First impressions and Final thoughts after using the power bank for some time.
Features:
Ultra-slim design with a hard plastic & aluminum alloy construction
High capacity 20,000mAh
Two USB charging ports (5v-1.0A/ 5v-2.1A)
Micro USB input for charging the power bank (5v-2A)
Blue LED digital charge indicator
Built in over-charge, and short circuit protection
Dimensions: 6.8 x 4.8 x 0.5 inches
Compatible with any USB charged products such as iPod, iPhone, iPad, Android tablets and phones, ETC.
First impressions:
After receiving the power bank the first thing i noticed and was pleased with was the packaging. When you buy a product you expect there to be in professional and quality packaging and they definitely did that with this power bank. After unpacking the power bank and holding it i was very pleased with the aluminum alloy construction. When researching power banks the materials used was one of the main factors for me choosing this one over some of the others on the market and im glad i did, In the hand the build quality and construction feels premium just like my HTC one and iPhone. While it is a slim unit i would not say its the lightest power bank it is after all 20,000mAh capacity which is a larger power bank . If you are interested in smaller lighter package you will also be shrinking the battery capacity so that was something i wasn't willing to compromise on. First thing i noticed during use was the digital LED capacity readout. This is a premium feature that also was a top factor for me choosing this power bank. With a quick slide of your finger across the read out screen you can see exactly the charge you have left, No more relying on the few led lights the other banks have to judge how much juice you have left. Overall my first impressions of the power bank was very positive. Between the premium build quality and features included i was very happy with my choice. Amazon LINK
Final Thoughts:
After using the Power Bank for some time my initial opinion did not change, In fact im not sure how i lasted before without one. The quality of the unit is outstanding, Being constructed from aluminum gives it some serious durability, and looks brand new after heavy use wile camping, traveling, beach trips, and school/ work. The battery capacity is outstanding, as a power user Ive always found myself killing my phone battery far to early in the day and now i always have a charger even wile away from on outlet. Ive also found it very useful for camping trips and power outages due to the large capacity you can charge many items on one single power bank charge which is very handy in those situations. Overall am very pleased with my purchase. Between the stylish build, quality of materials used and the overall charging performance i would recommend this to anyone in the market for a power bank. Amazon LINK

good job

This product actually looks awesome. The body is aluminum and I just loved the digital battery level indicator. I also use a Nexus 5 and when I am off to a trip I am always worried about my phone is about to die because when LTE, GPS is on and you're using camera with HDR it takes no time no drain the battery. I think this product can definitely solve the problem as it is very powerful.

I think its awesome

Great review, I'm looking to add some external power as I own a nexus 9 and 6 so this is a great buy.

Interesting thing... I think that I will buy one to charge my phone when I use it as a GPS on my motorbike....

Hmm this seems interesting it's been a couple days since you had it, any new updates on battery life and etc?

Do you think that is possible to charge it by a solar panel?

I have it also, really great device...
This one really hold my needs for power! I charge tablets and phones from it and totally forgot how it is to find out that your device is out of juice...
Tested it really thoroughly. Real capacity, it have LG Li-Po cells inside thats a thumb up for quality.
20000mAh is a really worth the price.
Tough and durable aluminum body saved it for me already from some falls and blows that other plastic power banks didn't hold...
Some images
The Cells
The PCB, really nice build...
The bank
The currents - it really can charge thing fast 2.1A on fast charging post or split to two..
I really recommend it, i threw away all my other power banks.. all the banks that were not real capacity and were total waste of money.
Hope the info helps someone...

And that's why this thing sucks:
Sold as being able to charge 2.1A ... only delivers barely above 1A
Forget about charging an iPad or tablet with this.

Hehe funny, you can clearly see in the image that it gives ~2A. this is what my cell phone and tablet took in that specific moment.
this charger gives the stated 2.1A if your device able to take it..
i have tested it by putting heating element on the so called smart port that gives the 2.1A and it handle this without a problem.
in order to discharge it fully from 100% to 0 took me ~7 hours...
