High capacity (2400 mAh) battery for HTC Artemis

Now there is a 2400 mAh battery. The manufacturer is Chinese and they claim this battery will last 100% longer than the original. Oh and the battery is also 100% bigger than the original so they supply the customised back battery cover.

So to sum on, there is a better battery, at least it looks like it has better battery life, so its your choice to get another or to get this one?

I think I keep the original battery.
This one is way too bulky and I think the Artemis is quite sexy the way it is.

i thing, it is joke

1000% AGREE !!!!!

Man, that makes the Artemis look ugly.

when you have business trips, you will change opinion.

This is a nice battery.
I am using it

I agree with what biou said, go on a longer trip where you have no access to electricity.
I bought a double capacity battery for my Ipaq rx3715 which already has one of the best battery life on the market. With the big battery I managed 40 hours continuous use with minimal settings, 20 with normal and 12 with heavy use like video or 8 with extra heavy use, so video + WLAN + big headphones.
When I watch videos my Artemis lasts about 8-10 hours but when I surf the web power drains so fast! I think it lasts for max. 3-4 hours with WLAN on.
I might buy one of these or I buy an emergency charger wit mini-USB. I still can't decide which one I want to use.

Where and whec is it going to be available? Shipping to eu?
I agree that it is ugly, but going on a hike in wood i would better have this fat one as a spare in case i got lost. Happened to me - first thing u notice when lost in wood is how fast gps battery starts to drain and that brings surge of adrenalin/panic.

I have a similar one to this which I use on my extended trips away from the office which also generate heavy phone use and often using a BT headset.
On the positive side it can last up to 3 times longer than the original battery without charge especially when using BT functions.
On the negative side however with the extended battery in use the PDA does not fit the desktop cradle or my GPS car holder.
In my opinion well worth having for those times away from an AC or car charge.

I want to buy one, but what battery is the best? I don't really trust all the cheap batterypacks on E-bay, do you guys have some experiences with a good battery?
Please help me pick one. Thanks

I bought mine from eBay and have not experienced any problems at all.
My battery is black in colour with white text. 2500mAh 3.7VDC and clearly marked for the DOPOD P800W so should be easy to identify on pics of the eBay listings.
My only word of caution is that the two top (closest to camera) plastic tabs on the battery cover are somewhat exposed and therefore fragile when removing the cover and can snap off from repeated swapping of extended battery back to standard battery.
My first cover tabs broke and I bought a second extended battery just to get a new cover when I snapped the tabs of the extended battery cover. Now I leave the extended battery on all the time.
I can do that because I located a different desktop cradle where I could cut some of the plastic away to accommodate my Artimas with the extended battery fitted. I also have replaced my OEM card holder with a universal style so I no longer have the issues which required me to swap back to the standard battery.
Extended battery is great and IMHO not too bulky despite the initial look in the photos.

Seidio 3500mah Extended Battery (w/ Pics)

I received my 3500mah on Friday with case. I haven't done any formal testing, but its been off the charger since last night on a fresh, untreated ROM and after a full day of work (including 35 minutes of Pandora on my commuter) its at 73%.
Now, some blown out pics:

Pros:
There is no debating this; the camera lens is now OFF of flat surfaces!
With the changed dimensions of the phone, I find it easier to hold.
If you like a more pronounced presence in your pants, this phone will help provide it
You know when you have left your phone behind. This is great if you are a /b/tard that can't remember anything.
Holy crap the battery life!
Battery does not get hot. I haven't felt a temp change at all at 1190Mhz.
The balance of the phone has been maintained.
Slip-free material on the rear cover feels better and is more tactile.
The rear cover snaps in tighter than the OEM.
Cons:
Its heavier. Not as much as you would think, but it definitely adds weight. Not necessarily always a bad thing.
Its fatter. The overall size reminds me more of a PDA than a phone now.
The material used on the rear cover is impervious to all sticky material. I ordered two covers, the other one has been ground down trying to fit an M2 disc on the back and nothing is working. I've tried 3M tape, 3M windshield tape, Super Glue, and JBWeld. Its futile.
There is always the off chance that a battery goes off in my hand like a grenade, killing me, my puppy, two cats, two chinchillas, and possibly my wife in one hellacious blaze of glory. Hopefully Bon Jovi will be playing at the time.
Conclusion:
[4.5/5] I ordered an extended battery that was twice the size of my regular battery with a rear cover replacement and got exactly what I expected. Its not for everyone; But if you want your phone to feel more substantial and have a battery that has a half-life apparently on par with the radioactive isotopes at Chernobyl, this might be the battery for you.
More to come as I play with it! Post your thoughts and experiences.

More (resized this time) pics, showing the pronounced camera protection.

I agree, I've had mine now for approx 2 weeks and could never go back. I've been running Hero's Baked Snacks Roms and can easily get 2 days with moderate use if needed (I charge every night however). I'm usually around 55% - 60% (approx) after a full day.
It's definitely fatter but the phone is large anyway. The only drawback for me is that i cant fit any case on it which kinda sucks..

Agreed. I wanted to show the recessed lens because the back cover kind of acts like a case. But I would like to skin it a little more.
I need to find a way to stick the Soundgate disc on the back. This is driving me insane.

I should be getting mine tomorrow. Can't wait.

I got mine in the mail today. When my girlfriend called to ask me what I was doing this morning, I responded, "waiting on my new battery, of course. " I was able to charge it before I left for work this evening. I had to restart 3x before I reached a full charge. I will be happy when its properly calibrated. Four hours later I am at 89%. I love it.

I wish they'd make this with a Rugged Case that fits it...the Rugged is bulky enough, I think they'd get a good amount of sales for that.

Where is the cheapest place to buy this? Has anyone compared it to the cheap eBay knockoffs?

Im thinking about buying this:
http://www.seidioonline.com/product-p/csr5hev4x-bk.htm
but before I do, has anyone bought one ? thoughts ?

why spend 69.95 for the 3500 that already comes with extended battery cover, then spend another 29.95 for another cover?

It is a great battery. Been using mine now for a few weeks and have gotten so used to it I don't even notice the bulge anymore. I does make it easier to hold.
Most days now I end up with about 70% battery left. Having the battery power there to do what you want to is nice.

mine will arrive Thursday, looking forward to it

Anybody have any experience with the "Innocell 1750mAh Slim Extended Life Battery" ? I want to buy this. I'd rather not have a big bulge on the back of my phone lol

Probably in the thread about the 1750mah Slim Extended Life Battery?

First night with my new battery, and Seidio did not disappoint. Just like with my G1 and extended battery, I was able to go 12 hours of very heavy use. Internet/Games/Phone/Text/ and I watched Avatar in HD using my V-Moda Remix headphones, and streamed about 3 hours of Pandora. After all that I was still at 35% before I gave up and went to bed.
There is no doubt that with moderate to heavy usage this phone will last two days and with light usage a week.

Ok I'm gonna put my flame suit on for this one but I purchased the ebay battery rated at 3000 mah and I think the rear cover looks much better than the seidio one. I get approximately 2 days of use on it while running the baked snacks rom and I only payed $ 10 shipped. The battery never gets hot and the battery life is amazing. I will post up pictures if you guys want but to me the seidio is very expensive and looks really ugly. It's just a bulge out of no where while the ebay one has a smoother transition.

No flaming here
I've been burned in the past by no-name gray market batteries and I sleep a little easier at night knowing I can hunt down the maker of this battery should it do the whole Holy Hand Grenade thing on me.
Seidio is much more likely to hold their quality control to a higher standard since they back the product with their name, whereas a no-name can sell you a 3000mAh battery that is really only a 1650 and they don't have to watch their name dragged through the mud.
Its really a personal preference, and its a very good thing that we both have the choice to put our money where we want.

[BATTERY][unboxing/review] Anker 1900Mah

Hey, My first unboxing/review so tell me if I have missed something, The batteries are here For 2 of them, along with a wall charger with a USB port on, for £16 (Used to be £12) And on it's own for £8 here, There will be hopefully alot of pictures and info through out, and currently I don't know how well they perform as I have only had 'em a couple hours, or if that they are actually 1900Mah, I'll take of the whit bit later and find out, however, 2 batteries for £16 with a wall charger and a year warranty, I'm not going to complain
All the pics were taken with my SGSII and I have re-sized them, Hopefully they are not to small but I didn't want them to be huge, Also sory for any blur, I don't have the steadiest hand in the world
First the box, Starting right from the beginning here if anyone cares, Very simplistic, cardboard and says Made in China on the top, nothing too special.

Inside the box, Packed neatly.
What's in the box, the 2 batteries, charger and UK adapter (You'll see why later)
The charging unit, Which has (I think, Never been, there) a USA Plug built in, which...
Flips out to look like this.
The UK plug on it, (It slides right on)
Anddd,, Where the battery goes.
The battery (Both sides) With all the info on, Looks and feels high quality.
With the battery in.
Some of the instruction booklet (If you can read it)
It whilst charging, The light is actually nicer in person and more pink (Also fit's the original battery.. Obviously )
It fully charged/not charging, Blue/Purple light (again looks brighter and nicer in person)
Some comparison photo's between the Stock and Anker battery.
And that's all, I'll post how well it performs asap, But to be fair im going to give it the 3 recharge cycles as stated in the manual, Then compare it to the original.
Thanks for reading

great looking forward to the test results
wondering though how come some anker can put 1900mah in a battery the same sized as samsung and samsung cant do such thing as a default? hmm

Just turned everything on and clocked it up now to drain the battery , Should be done by tomorrow ,
I guess it's to save money on Samsung's half, But I'm not too sure either.

Intresting!
Subscribe this post, couse i'm really curious. Maybe i'll buy one for me

Had the same battery on my sensation, worked like a charm and gave me an extra 20-30% more juice. Don't know how it will preform on the SGS II though..

I'm curious too. My cheap Chinese battery's say their 1800mAh and is more like 1300-1400mAh which was no surprise at the time because its easy to print whatever on the sticker without proper testing. See here for proper testing http://translate.googleusercontent....h.html&usg=ALkJrhje4iAnKMYySrm1MUK2mZPX9GLr8Q and a few more batteries http://translate.google.com/transla...e/samsung-galaxy-s-ii-2-3500-mah-2430mah.html
The charger is identical to the one I got with my ebay batteries. http://cgi.ebay.com.au/ws/eBayISAPI.dll?ViewItem&item=270758612241&ssPageName=ADME:X:RTQ:AU:1123
If you can't tell I'm a little sceptical about the 1900mAh claim but you never know. So I have also clicked subscribe

As soon as you tell me how it works, I'm buying it in the states. This one looks very promising. Is it the same size as the original? Thanks.

same size as the original, however as far as I can tell its ever so slightly thicker and heavier but not noticeable, also it seems promosing : D I've been trying to drain and I'm still at 16 percent, where as my stock would have easily died by now

It should improve after a few drain/charge cycles. Do you think this is the best battery without increasing the size of your phone?

Send one of these babies to eug, he is able to accurately measure the capacity.
Everything else is just pure speculation and I'm pretty sure these batteries will also turn out to be 1300-1400mAh.

You think I should cancel my order that I just placed?

i have had this for 2 weeks. Pretty good. Does the job. no overheating issues.
After the first 5 charge cycles the batteries take about 6 hours to charge in the dock, which is fine because trickle charging is good. And having 2 spare batteries, you can leave one on charge and have 1 spare with you.
Battery life increase....nothing spectacular , someone that knows how to test it should comment. I am interested to know the findings

Sorry but that battery didnt work. Already tested and the stock battery is more better. Just let the battery drain to 5% and you will see.

If these are in fact the same as the 1800mAh (1300-1400mAh) then they are actually expensive compared to them The charger is definitely inflated in price for just a different sticker.

so is this brand a good brand??

Damn well thanks for the info guys, 1400mah it is then,

I haven't done any lab tests but its feels the same as stock battery to me on day to day usage.
I bought from the brand because they have excellent reviews on htc sensation, people report 20% extra battery. check amazon reviews

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.

Vote: 8000mah Nexus 5 extended Battery. Will you buy?

I love travel, especially remote area. I want a great phone with long lasting battery. Nexus 5 is a great phone, but battery only last less one day under moderate use.
So I made a extended battery, the capacity is about 8000mah, 3.6 times of the stock battery:

I am waiting for the 3D printed back cover to finish this project. According to my test, under normal use, this phone can last 3-5 days with one full charge. The charge time is about 5-6 hours. My wife love it too, I am making another one for her. She asked me why don't mass produce it and sell?
The only thing about this extended battery is the complexity. Like other recent cell phones, Neuxs 5 put NFC, wireless charging coil, antennas and vibrator on the back cover. So to make this extended battery work on Nexus 5, beside the 8000mah battery. I also designed NFC Coil, Wireless Charging Coil, WiFi Antenna, GPS Antenna, and a vibrator. All these components adds up the cost. The retail price may reach $70-80.
I started this battery as a hobby. Is here anybody like my design, and think I should mass produce it? Will you upgrade your Nexus5's battery to 3.6 times for $70-80?

Yes!!!

At that price? Yes, really just depends on the bulk added
-guess

Looking good! 8000mAH is a lot of juice. How much bulk (in term of thickness and weight) is this going to add?

This is a great idea, but way too big. If you made one with a 2000mah battery I'd be all over it. Good luck!

I would take one for that price.

God damn!! I wouldn't mind using it, ingress destroys my battery.

Sheesh that's a lotta juice!
Looking forward to seeing that cover and how the phone looks after juicing

How about adding a MicroSD slot, I'd imagine you could graft it onto the usb port somehow... I never understood why nobody does that.

Technically, MicroSD slot is doable with the usb port, but we may need to cut off the data wires of the usb port. I haven't tried that yet. Don't know if the SD card and USB data can be connected at the same time to the PC / Mac.
==========================================
Thanks Everybody for the supports. I am glad to see you guys are interested.
I worry most about this mod is the installation part, since Nexus 5 is not deisgned with a removable battery. Please let me know if the following installation is suitable for most of users:
1. We need to take your nexus 5 apart to take the original battery out.
2. Install the small battery of the extended battery and plug in the connectors.
3. Install the circuit board which connects the vibrator, antennas and coils.
4. Flip the large battery back to cover the small battery.
5. Connect the coils on the large battery to the circuit board.
6. Snap the extended battery cover on. (Coming Soon).
Please let me know how do you guys think about the installation part.

About the thickness: according to the 3D file, the thickness is about 17.5mm. I think it's okay.
The last phone with extended battery I used is HTC Sensation XE, with the extended battery is 18.5mm for only 3800mah
The thickness of galaxy s5 is even thicker: 21.4mm for 7500mah (With this thickness, we can make about 10000mah for nexus 5).
The thickness of s4 is 17mm for 6400mah

OMG like really this would be awesome could you post some pictures of your phone with the inserted?
And ps be sure to ship outside the US too

The worst of Nexus 5 is the battery...
This "mod" its awesome! I cant wait to see the Nexus 5 ensambled with the 8000mAh battery!!

I'll Buy

this is awesome. Though i would prefer something along the lines of a 3000mah battery, just so its that much thinner

This looks pretty cool. Can't wait to see how it turns out.

Just perfect
This would be soooooo good. The installation doesnt look hard and you are getting 8000 mAh. Ridiculously good.
Waiting to see that final image with the printed back cover.
I will buy it

This is very good work you've done. But it is a very niche product. Not many people are willing and able to disassemble their phone. Fewer of them own a Nexus 5. Fewer of those want a bigger battery and will ever learn about your product. And fewer still will swallow the price.
I encourage you to charge as much money as you need to, so you can make up for the low sales volume. Don't short-change yourself. This looks like a $100+ kit to me. Maybe you can hold a group buy, massdrop-style, where the price falls as more people commit to buy.

I'd definitely pay for it, well worth the money! but would want a bulky case to fit it lol.
Easily $100 or more wouldnt pay more than $150!
Like he said it's something only certain people would buy and be able to fit it properly, well I would!

I would love to have that battery power but i'm afraid that thing will ruin camera performance.
An extension battery pack can't add any thickness where the camera sits, otherwise it will impact on camera

If it's not bulky, I don't mind paying up to $100-$150. It would be nice if you can make the size smaller and fit it inside.
