O2 XDA Extended Battery - any opnions, experience?

Hi
I'm about buying an Extended Battery for my good ol' XDA...do you have any experiences and/or opnions?

Well the official extended battery works well, it makes the phone very chunky though, my problem is I dropped the phone and broke the plastic locator tag so the battery doesnt sit on the phone properly, the bottom sticks out, probably have to use velcro or similar. :?

Is it work with WM2003SE? Or do you need any drivers?

No drivers, its just an electrical connection.

Hi, my first post hope it helps even though its a couople of months late!
I have just bought an extended battery off ebay uk from HK took 4 days to come and took me 10 mins to change over. Cost £12 delivered.
Lasts for ever. Got extened battery for old ipaq as well from sameguy just as good.

Got mine from www.lionbattery.com. Some ppl said it won't charge from cradle and resets device... I don't have these issues so far... It charges from cradle and doesn't reset device when I change it. But I've been using it only for 3 days so can't really give a good advice.
Also have a look at:
http://forum.xda-developers.com/viewtopic.php?t=24355&highlight=high+capacity+battery

I just bought an external battery on eBay, and it works great, but a bit bulky, and I don't have a case that will fit.
I also bought a new 1750 mAh replacement battery, and it works so well that the external battery mostly resides in my refrigerator! I expect I will use the external battery on camping and boating trips, as I keep the phone in a waterproof PDA case, and it has the extra room.
The 1750 mAh battery is a HUGE improvement over the stock 1200 mAh, it took about 10 minutes to change it out. They even sent out a couple of the special TORX screwdrivers needed!
I spent, including shipping, $22.00 for the new battery, and $22.00 for the external one.

The XDA I (Wallaby) with the genuine battery backpack fits fine inside the o2 XDA Executive case. You can get this case on eBay.co.uk for around £7.50
Just search ebay for

Extended batteries (3500mah in this case)

Well... so far I've ordered a 3500mah extended battery from Hong Kong.. but as I believe this will take rather a long time to get here... I've ordered another one from the UK as well from ECELL, which apparently has a silver extended cover.
I'm well aware that these are likely cack batteries and I have a plan for that
Basically I'm hoping that whichever one I consider to be the worst will either die on me... or I will simply end it's life prematurely. I am going to cut open the battery (Carefully!) and try to replace the cell's with two Genuine OEM 1500 mah batteries, for a true 3000mah. I bit elaborate but I think it should be possible as long as I cut in the right places.
EDIT: I found genuine LG batteries for about £8.50 each plus about £5 postage, so will order 2 batteries for around £22. They are special order though, so will take 14-28 days. (I am also getting them to confirm the capacity is defo 1500mah, as no point buying them otherwise.)
Update: Images in post #29 : http://forum.xda-developers.com/showpost.php?p=23120430&postcount=29

Well.. I was getting a little impatient... so when I was really tired (and may just a little to drink), I ordered one from ECELL on ebay. It had a silver cover and a 3600mah battery (We all know it isn't that much), and was listed for the 2x P990. Turns up.. it's for the LG Optimus S :-( Bummer. Just trying to get a return/refund.
So... experiment is delayed somewhat.
Update: Two LG OEM batteries have been ordered ; The incorrect extended battery sent back ; Still awaiting the HK Extended battery. Bizarrely I thought I actually ordered a 2nd UK based battery.. but I was so tired I think I forgot to do it lol. Can't wait to have a play with these

Refund form ECELL given without issue Have now received the 3500mah battery, and just running that to see how thing's are with it. I am waiting on the two OEM batteries to turn up from LG before I can start modding this extended battery.
Since I also have a bigger case now, I am going to look to see if I can play around with an external antenna as well.. and maybe fit a bigger antenna inside the expanded case. With that in mind I have ordered two antenna's of different types to see which one fits (expensive.. but then at least we all know )

Sounds really interesting.. keep us updated please!

i got the 2400Mah battery(2 days of usage) i'm looking forward for you're results
specially the modded one pictures will also be great if u can.
thanks!

Apparently the LG batteries have been dispatched now, so should get them within a few days. Only annoying thing is that even LG were unable to confirm whether these batteries I'm getting are 1500mah. I will be gutted if they are not lol.
btw.. you should see my desk at present at home. I have about 5 phones, four of them in bits awaiting tinkering, LED bike lights (all modified), circuit boards from laptops everywhere, reparing a 4x 18650 battery pack + routers etc lol. And I just realised that I actually don't know where my soldering iron is ROFL. Must dig one out.
Anyway... I'm looking forward to it and if I can get it working, I'll put up pics etc. I'm very interested in trying to get the temp sensor working (although I realise it may only work for one of the batteries.).
P.s. as for extended cases and covers I bought this w w w.ebay.co.uk/itm/Clear-Black-Trim-Rubber-Case-Cover-LCD-Film-Pro-LG-Optimus-2X-G2X-/180782656771?pt=UK_MobilePhones_MobilePhonesCasesP ouches&hash=item2a177c6d03 and then cut out the back clear part. It's not a perfect fit, but it will work for the moment (Buy at your own risk.. I actually stretched mine too much when getting the clear part out).

Genuine LG batteries have just arrived about 30 seconds ago. They are 1500mah
So with the delivery charge added in they were £11.04 each (£8.49 each without delivery charge). So if you ordered more it would be less due to the one time delivery charge of £5.10. Not bad for a 1500mah genuine battery! Batteries dated 10/09/2011.

Yes. I've now ordered a second "3500" mah battery so I have a spare cover and shell in case I **** anything up. I am just trying to gauge the capacity of the 3500 battery. On my first run it lastest almost 2 days on stock rom, with a fair amount of use. I would prob say only around 2000mah at a guess though.
I'm just trying to get it to run down again for a 2nd charge now.
Once all that's done, I'll open it up and start tinkering I will have to get both the LG batteries to the same state of charge as well (same voltage level) before hooking them up.)
Bear in mind I've spent £22 on original batteries that I am about to hack open for the cells inside, so there is no going back lol. Pretty expensive mistake if I **** it up relatively speaking.

no doubt it could be an expensive mistake, but if u succeed which i think you will the results will be probably a 4 day battery. so i think its worth it
i got the 2450Mah battery and it holds about 2 days with medium usage, so im really thrilled about ure test as i dont care about the size of the phone,
if you can share pictures it will be great you can also p.m if u want!!
thanks.
Shpapy.

No problem, will do
I charged the battery again last night, and rapid drained it running bluetooth (nothing connected), some GPS usage and wifi with smartshare running a video across from my NAS drive. In the morning it was down to about 25 percent so tried GPS on cycle to work and then drained it with music and GPS until 1%. Charged it without using it, and it's reporting about 1900mah estimated for the battery. I don't rate the estimator as highly accurate btw, but it's a guide .
I will try to take the battery apart tonight if I can. Not sure on best way to open it though, as I will need to reuse the carcass.

Damn.. was taking it apart and fried the circuit it came with. Unfortunately the metal legs that bring power from either side slipped off and touch the outer shell of the battery, was enough for a small yellow spark :-( oh well. (EDIT: Hmm.. circuit may still be alive actually...)
It's two batteries pressed together with several layers of thin plastic between them, either for insulation, spacing or both. I'm actually pretty surprised the cells weren't isolated better from each other.
Update 1: Well, for the first time.. I just managed to burn myself with electricity opps. These packs are really badly isolated. Shorted it on the tip of my finger... beginning to hurt lol. There are NO ratings on these batteries whatsoever. However, one thing they are is... amazingly well balanced. Just measured them and they are both exactly 3.78V's.
Update 2: The circuit and LG Battery will NOT fit directly into the old casing. There will need to either a mod to the extended casing, or we'll just have to 'go without', and make a casing up. It's looking like it's best to do without using the old battery at all actually, and just wire the two batteries together using the LG circuitry. (Well only one of the circuits).
Update 3: Will dig out the soldering iron tonight and get this double battery running
Update 4: Have VERY BADLY soldered the batteries together and combined battery is now charging in the phone. Due to the excess solder on the sides the battery is not quite proper fit, so I will have to redo it at some point. Really very dissappointed with how awful the soldering is, I will simply HAVE to redo it once this experiment is tested. Any tips on a soldering iron chaps? On the plus side, the one thing I do get is a temperature reading :-D
Tip number 1: Quickly snip the circuit off first and DO NOT let it touch the side of the battery casing, it will short out.
TIp number 2: h t t p://www.technfun.com/pages/article.php?id=22 Excellent guide. Take note of the safety tip!!!!
Points of interest
A) The extended battery is EXACTLY double the width of an LG battery.
B) LG OEM Batteries are made by Sanyo
C) Don't use a conventional soldering iron... it is almost impossible to solder the negative side and you will end up overheating the battery if you are not careful. (Any tips here guys?)

Charge battery up last night, and stayed up wayy too late trying to drain it.
Technique... used the 'flashlight' app to keep the LED on, turned on bluetooth, turned on wifi, and use smartshare to stream a movie (at full screen brightness) to the phone. Played Dungeon Defenders for a while as well at full brighness so hopefully the graphics core would take more power. Battery Temp got as high as 40C under 1400mah draw. Odd thing was that battery widget pro at times reported +25000 Mah(ish), yes PLUS '+', and 25000mah, that's just insane..not sure where it was getting the figures from :-(
7% battery left when I put it down, voltage was 3.550 or very close. This morning, voltage it still had 7% left and voltage had increased to 3.7 ish. Guessing it's because the battery was warm last night when under heavy strain, and now it's relaxed and cooled it's feeling better lol. (Or maybe something else?)
Running gps client down now in attempt to drain the rest before recharging. Ideally want to get it down to 1% before a full charge.

cool progress , can we get some pictures of the new battery?
how were u able to fit it in? i get u got a bigger case but still....
share with us ure images / knowledge its sounds really cool doing.

I basically copied what they had done on the 3500mah battery, and merely connected up the positive to positive and negative to negative terminals of the batteries using thin strips of metal, and only used one circuit from the LG battery. Basically I parallel the batteries to increase capacity.
I used a small spacer to keep the batteries seperated, but thinking about it, I could have use the bodies themselves as the 'negative' but it wouldn't have been a good connection). I then just taped the battery up and use the 3500mah battery sticker to hold it all together.
This really is just a 'prove it works' / prototype, and I will remake it neater, although I may have to buy a better soldering iron.
Pics later.
Note: After charging back up from 1% this morning to 100%, the 'estimated' mah by Battery Widget Pro is 1551mah. This would indicate to me that one battery is not connected properly unfortunately. I'm gonna run the battery and see how long it lasts under general usage. If it lasts only a day and a half, then I suspect I will have to resolder.

I bought a 3500mah half a year back and it wasn't any good. Twice the width but lasts the same as the original one. It'll be good if you could show us some pictures? I may consider making one too!

To be fair the estimated capacity of the 3500mah was around 1800 to 2000 mah. Pretty good considering it came with an extended back cover for under £5. It does seem entirely random though, and I was never comfortable without a temperature sensor.
The work I have done so far is rubbish to be honest. I thought I'd make a better job of soldering. I will have to redo it, as the fit is terrible due to the solder being too big/messy, and the connections are not very or or not working/broken.

Can't wait to see the results.

For some reason, battery widget pro was recording very high mah draw/drain. I do not believe I soldered the negative terminals well enough. I took it apart and tried to prise a little flap of metal up for soldering, and managed to rip the terminal off the pack. I will do my best to remedy this of course and let you chaps know the result.

I also have the 3500 mAH and I was wondering if it was really giving 3500 mAH. I'm getting about 1.5 days on this battery with moderate usage. Heavy usage I get about a day. I wonder what I'm doing wrong. I think it's supposed to last longer.

[OFFICIAL] Mugen Power 6400mah Battery Review

http://www.mugen-power-batteries.co...-samsung-galaxy-note-2-with-battery-door.html
Packaging:
The Mugen Power 6400mah Extended Battery for the Samsung Galaxy Note II comes in a very simple yet elegant packaging encasing the extended battery, custom battery door with stand, and also a leather pouch.
Looks:
Taken out of the packaging, the initial thought that jumps to mind is THICK. Yes, the 6400mah rated at more than double the battery life of the OEM battery is also double the thickness of the OEM battery. However, this was expected as doubling anything always come with a price. Minor print on the battery introduces its specifications (3.8V / 6400mah) along with several caution warnings.
The extended battery back comes with a surprise as well. The NFC chip is built into the extended backplate. Thus, consumers would not have to make do with no NFC if they opt for the Mugen Power Extended Battery. Best of both worlds, who doesn’t want that? Also, the backcover has a very detailed diamond shaped pattern that provides a textured feel to improve grip. The flash and camera cutouts are perfectly aligned and cut along with the SPEN cutout as well. The kickstand on this unit is much better than any of the previously reviewed batteries for other phones. Mugen Power seemed to have finally fixed their flimsy stand issue as the current stand provides support and rigidity when opened, and sits tight and flush with the back when closed.
The leather pouch included is BIG, big to a point that I have not found an excuse to transfer from my current slim case to this pouch. However, for those leather lovers out there, this may hit the sweet spot for you. Who thought you’d be getting a pouch when all you care for is the battery? Just to make one thing clear, the pouch DOES NOT seem to be made for the extended battery cover, as the phone sits REALLY tight in there, which does not seem right. However, with OEM battery, the phone fits in the pouch just fine.
Performance:
This battery is AMAZING. The Note 2 itself already has one of the most excellent battery life in the android crowd, but this battery takes it another step further. With the original 3100mah battery, I am able to make it just past 2 days of moderate usage with an average of 5 hours screen on. This usage includes surfing, slight 1 hour gaming, videos, lots and lots and lots of chatting and texting, and 30 minutes of calling.
With the Mugen Battery, regular usage lasted me over 4 DAYS with similar usage stated above. This makes true Mugen’s claim of doubling the battery life, and really comes in handy if you are going on a long trip where a wall plug becomes a luxury.
I also wanted to see how the battery would do if I stressed on gaming and video watching. In this area, I was even more surprised. The screen shots attached show clearly how I tested the battery. In one day, of over 11 hours screen on, around 4 of them was due to very intense high graphics ONLINE gaming, which is a BIG battery sucker. Additionally, web surfing and video watching along with tapatalk are amongst the remaining few hours of usage. (BRIGHTNESS ALWAYS AT 50%) No matter what you say about this battery, for gamers, this is a MUST. I used to have to change/charge my battery more 5 times (not 0-100 charges) throughout the day if I game this much. With mugen, that worry is gone, as I am 100% certain that no matter what I do with my phone. It would last me through the day, EASY.
Nothing in the world is made perfect, and so isn’t the Mugen Power Extended Battery. Though the cover fits the phone perfectly with the extended battery inside, there is a slight hollowness within the phone that allows the battery to shift around inside. Its not to a level such that the battery would loose its connection, but it just feels hollow and when you feel the battery move inside, it just annoys you. An easy fix was applied by adding a business card on top of the battery then closing the phone.
SO, it you are planning on a long trip, or if you are a avid gamer/ user, and is not satisfied with your battery life, Mugen Power's 6400mah battery for your galaxy note 2 really is the way to go as they produce one of the best quality batteries on the market with proper customer support. One downside however, is that you have to overcome that steep price and also a slight downgrade in looks of your phone.
OH, and IT STILL DOES FIT INSIDE YOUR POCKET JUST FINE…

Additional Pictures

excellent review, I'm fairly sure I'll pick one up before i go to europe in a couple months. For now though on a regular day to day basis I use about 45-55% of my battery in a full day (6am-10pm). Probably 25% of the battery is from work and the other 25% is at home.

i just got one and....
It's a real pain in the ass.
Charged it for 12 hrs.
Started with battery drain apps, but don't feel like stressing all the components that much.
So I'm using it my normal heavy amount, which makes me always keep my mind on the battery.
Well it just Won't discharge! !!!!
At this rate it'll take me more that a week to train the battery with 5 cycles.
No Way drain in a day. No matter what I do.
How annoying.

Nice review. I still could never pay that much. I just got the hyperion 6300 and tpu case for under $30. I am very impressed with its quality. So far people are having almost the exact same results with the anker and hyperion as the op.

Thanks.
If I get a gnote2 I will probably pick this up as well.
Though I kinda hope for the gnote3 to have a native 6000mah battery (with aftermarket upgrades going to 10k+).

Nice review, I'm thinking of buying one of these, but I can't say that I like the bulkiness. My Note 2 is sexy as it is with my UAG cover, oh well, I'll sleep on it.

thickness?

Not to knock down the product, as you guys know I do reviews of numerous accessories in this forum and try to stay fare to product value (I will tell you if its a premium product and extra price gets you extra quality, etc.). But when you look at Mugen 6400 mAh for $105 and Anker 6200 mAh for $17 how do you justify price difference? Both are trusted companies in my book. Yes, Mugen battery cover is premium with kickstand and built-in NFC (although even video reviewer had some issues?). But what else?!? That is a HUGE price difference. Any idea? I have tested Innocell 4500 mAh which I found to have a higher capacity, closer to 500 mAh, and I couldn't justify its price either. The only advantage in there was ACTIVE Extended rugged case to use with typical double thickness extended batteries.

I suppose because Mugen can be trusted (so many of the extended batteries are china fakes...) and provide warrantly.

Recommendation for spare battery and charger

Can someone recommend a good replacement battery to be used as a spare, and then a desktop charger for the extra battery?
There are many varieties and sources, which one(s) have worked for you -- and would you buy them again?

I got a 3100 mah anker on amazon. Performs the same as stock I think. Doesn't come with a recharger though.

I bought this one. Works great.

Edit: I've had Anker batteries for my GS2 when I had it. Had no problems whatsoever.

why not just get an external battery instead of a battery and battery charger? Anker makes a 10kmah one that is fairly cheap.

Why not the official Samsung one on the Samsung website?
Its priced at $50, comes with the same battery that comes with the phone and folds closed for travel. Also works as a stand for the phone.
If you search you can get a 50% off coupon and get it for only $24.99....seems like a great deal to me.
I plan on getting one myself for my upcoming 2 week trip.....
Sent From My Ginormous Note 2

I like to live lavishly so I own the official Samsung charger that includes the extra battery, the official samsung 9000mah external battery, and the 10,000mah anker external battery someone mentioned above. I can recommend all of them.
One thing to note though. The 9000mah samsung external charger just has one USB port for charging. It also doesn't include its own charger to recharge it. The 10,000mah anker external battery has its own charger included, 2 USB charging ports, and a 3rd output to charge laptops (includes multiple adapters).

I've got for present gold battery that was purchased on alibaba, which has a rated output of 4200m, which is absolutely not true. At first I was skeptical and I have to admit that battery performed well. Who use it and carry it back in my purse in case I am not able to recharge the phone with the original battery. I understand the alibaba the battery is pretty cheap, and in my humble opinion, if the battery is used as a backup should not throw the extra money that would be well for us for a few hours ...

I loved having spare batteries for my Galaxy S3 and I had an Anker (same size and capacity of original Samsung one) which would last longer than the stock Samsung battery so I figured that's what I'd buy now that I have a Note 2. I bought the 2-pack with external charger from Amazon (click here for link) and I'm somewhat disappointed. Both of the Anker batteries stick out about 1-2mm at the bottom (above the speaker) which prevents the back cover from snapping shut completely. This isn't that big of a deal since I use a TPU case, but it's disappointing. I haven't been through enough cycles to test whether the battery life is the same, but considering my phone lasts over 2 days on a charge with the stock battery it'll take a while.
I did, however, order a single QCell battery with external charger from Amazon (click here for link) and UPS literally dropped it off 10 minutes ago. I immediately tried putting it in the phone and it sits flush, so I already like it more than the Anker. It only has 56% charge so I'll have to measure the battery life after a couple more cycles.
I'd recommend buying a single battery with external charger and making sure you like it before ordering a second spare if you want. I'm highly considering returning the Ankers and buying another QCell after I finish all my testing.

Do the Anker batteries stick out at the bottom a little bit? Does your back cover snap shut completely at the bottom with either of the Ankers installed?

I don't think they stuck out when I had one in. I'll double check when I get home from work, though. I have the stock battery in right now.

My batteries don't stick out. My back cover snaps completely shut and I'm able to put my diztronic case on it, too. I bought it a little over a week ago. I had them just in case at the Chicago Auto Show.
I prefer spare batteries than external battery packs and what not. It was very useful at Universal Studios. I was able to just pop the dead battery out and put a fresh one in as opposed to plugging a battery pack in.

I agree about batteries vs. External charger. I like being able to pop in a new battery and being at 100%. I don't want to wait to have it charge when I want to use it.
I just got my Anker batteries last night I will be doing my "scientific" experiments with them tonight to compare the two.

Its priced at $50, comes with the same battery that comes with the phone and folds closed for travel. Also works as a stand for the phone.
If you search you can get a 50% off coupon and get it for only $24.99....seems like a great deal to me.
I plan on getting one myself for my upcoming 2 week trip.....

Yeah I think this is what I'm going to do.
Thanks all for the input, having the native samsung battery seems to make the most sense.

Review: Zerolemon 5500mah Note 8 Battery Case

First, I did receive a review sample from ZeroLemon.
If you're looking for a slim solution, this is NOT your choice, if you're looking for massive amounts of additional power on the go without having to carry a cable and external battery, then this IS your solution.
As I'm sure everyone will mention, it's LARGE. Until battery tech gets smaller, you gotta cram that battery somewhere. It's pretty hefty as well. If you wanted with this battery pack, you could outlast everyone around you in a marathon Pokemon Go session, long flights of movies won't be a problem. It's not going to provide any screen protection if dropped, but it might give you some arm workouts as you use the phone.
It's brainless to use. Plug your Note 8 into the battery case. All the button passthru's worked fine and aligned up. You are still "capable" of using the fingerprint reader, expect a bit more "reach" to get there. The case itself doesn't block the camera at all. No ghosting of the case in your photos.
If I were designing this, I would have added a flipout kickstand so you could just sit and watch movies without having to hold the bulk.
Product Packaging:
Packaging is quite simple, it’s a white ziplock bag and a brown cardboard box. There isn’t much in terms of instructions, just a small flip out pamphlet that instructs you on how to plug in the battery and case.
The battery attaches to the Note 8 via the USB-C port on the phone. The battery attachment also charges through a USB-C female port, so there is no need to change chargers or cables that you are already using with the phone.
Battery Usage:
I charged the case for approximately 12 hours before initial use – as instructed on the white ziplock bag that it all comes in.
The battery/case:
It’s a simple TPU case. It has a matte texture that feels good in the hands and prevents slippage.
After testing the battery case with the camera flash, I found no issues.
There is no need to remove the phone from the attachment in order to transfer files to your computer – something that is not possible with another extended battery case I tried using prior to this one.
Charging:
The battery itself does not support fast charging from the battery to the Note 8, but it does allow for pass through quick charging of your phone if you connect the battery case to your Samsung fast charger.
Pros:
Good extended capacity
Power on/off button
Solid construction of battery and case
Pass-through quick charging
Data transfer pass-through
Worked first time. Living up to name ZeroLemon.
Case itself is grippy and comfortable
Cons:
No NFC
No QI charging
Recessed fingerprint reader
Noticeable increase in weight and thickness of the phone
Needs a flip out kickstand.

Interestingly, if you try to go to the product page its a page saying "Oops - We couldn't find that one"

Interesting that they make two of them now. I wonder how much thinner the 5500 will be compared to the 10000 one.

I saw that 5500 version a few weeks ago before the 10,000 mah one was listed and didn't like the way it looked. The 10,000mah one looks decent, I need to know if it will work with the Whitestone Dome though.

When you are charging this, does the phone and the case get charged in parallel? Or the phone first, then the case etc.
Also how long does it take to charge the case itself, with the phone in it?

I like mine. It's a little smaller and the case is refreshed from older models I've used from ZL

Well I went thru 2 10000 cases in 1 week and both failed. Then I bought this slim one. Worked great for 2 charges and then would not take charge from factory charger. Will only charge from pc. Contacted zerolemon and was told must be defective cable. Lol. Yet charges my phone properly. Zerolemon is garbage and I recommend everyone to stay away from it. Last 2 phones product has gone to worthless in less then 2 weeks.

All their 5500 seems to be is a rebranded knockoff of the ebay versions for about $20 more. The 10 000 version looks like there's. Bottom line, like the OP said. It's heavy, no wireless charging, no magnet, no nfc. Those three are a killer, I regret not waiting for mophie's more expensive alternative.

The Mophie one is only 2950mAh and can only charge the phone 50% of juice.

Sorry I don't have it. I want to purchase it but it is currently out of stock.
It should be smaller in size than zerolemon as it has smaller capacity, I think.
Here are some video fyi:
