Yeah I defo will post pics. I'm doing a different case but will see how it turns out :P

Should hopefully get battery tomorrow.

So on the battery connector do you mean to cut the top black smooth plastic park and that will give me good contacts without mucking with the connection to the phone.

There's 4 pins on the battery. Is it defo the outside ones I have to solder. And the same outside ones on the smasung battery? Think there's 3 on the Samsung battery.

Cheers

I've just had a go at it with a knife. I knocked two little black plastic bit off each side. Can see any copper bits though. I'll post a pic in a sec to see if they are the right bits to solder to.
[Nexus 4 General] shenery:
How does that look? Have I got the right pins?
[Nexus 4 General] tommmtom:
Yep :) just solder carefully (so it doesn't melt :P) some wires to them, the two outside ones marked + & -

The Samsung battery will have the + & - signs on its contacts so just solder the two +'s together and the two -'s! Make sure the voltage of the two batteries is the same before you solder them together though, easiest way I found was to either run benchmarks on the nexus 4 to drain it down to the Samsung battery level, or plug the nexus into the charger if it was below the Samsung battery voltage :)

BTW....the two left most contacts in your pic are the same (connected to each other) so its only 3 pins really, don't know why they have 4!!!!
[Nexus 4 General] shenery:
Hey thanks for getting back to me and good shout with the benchmarks ;)

Been reading a bit about wiring 2 battery's of different capacities in parallel and I'm getting a lot of conflicting information. Do you think this will be safe or should I just go for an s3 one? One guy said that once the 2100mah battery charges it will then over charge when its trying to charger the larger capacity batter causing a fault. And then there's people saying that they have done it and its been fine. What do you think?
[Nexus 4 General] tommmtom:
Shouldn't be a problem....each battery already has its own charging circuit built in which stops charging when that battery is full.

All that will happen is it will charge slowly...both batteries will always stay at the same voltage, one won't charge to say 4.1v whilst the other is at 4.2v :)
[Nexus 4 General] shenery:
Ok sounds good! Hoping my battery comes today :)
[Nexus 4 General] Alicklee:
a few questions

1. have you tried using battery widget to change the mAh readout on the phone so the battery meter reads right?

2. I thinking of doing this with 3 battery will that me too big?

3. how did you get the back made and how was the antenna/nfc/wifi remounted on the back?

4. also will the bumper case still fit?

thanks
[Nexus 4 General] noowb00:
How thick did the phone ended up? I don't mind the thickness but I'd like to imagine how fat my Nexus 4 will become if I do this hack on it :P Or you can just post a picture of its side :D

[Nexus 4 General] stickbo:
Wow man, nice job.
[Nexus 4 General] BillXia:
That is amazing. But don't you think a 2100mah battery is enough for daily use? I think original glass back cover is very beautiful.
[Nexus 4 General] noowb00:
No. 2100mAh on the Nexus 4 is certainly not enough. ... Unless a charging port is always available to you.
[Nexus 4 General] m4r0v3r:
my backs finally kicked it :/
[Nexus 4 General] bpdev:
Wow thats awesome! How much does your N4 weigh after this mod?
[Nexus 4 General] dodgebizkit:
this is mentallllllll lol
[Nexus 4 General] acilsekirlet:
If there would be thinner batteries, the bulkiness would be avoided.

In addition, the soldering step would be avoidable if you purchase a spare aftermarket battery for N4. Just place the ribbon charging cables on top of each other and try to do necessary contacts. v+ v-.

I don't know the exact specs, but If there is enough space, we may clean up all the adhesive beneath the battery, strip the additional clothing on the batteries, strip the nfc part of the original back cover then try to fit the back cover.

I believe that we should look also for the batteries of similar non-removable hand sets, like iPhone5, or HTC One and try to determine the best battery to do this work by keeping the original back cover.
[Nexus 4 General] rsd79:
I would pay for this if there is an easier solution. But nice job in showing us that it can be done
[Nexus 4 General] nqk:
4200mA, good for you. But it looks like a humpback whale. :D
[Nexus 4 General] MrToastedAndroid:
I wonder how much it would weigh!
[Nexus 4 General] netodroid:
OMG! what have you done to your Nexus? :cowboy:
[Nexus 4 General] ultrapirate:
That's just great!
[Nexus 4 General] tongjia19:
That's really cool man.

[Nexus 4 General] thesebastian:
I have 2 questions:

1) Is Stock battery needed in order to have a working NFC? (Like with Galaxy Nexus i9250).

2) Is Wireless Charging working with a non-stock battery?

I'm waiting for Polarcell or Anker to create a better replacement battery for Nexus 4 :D (with original size).
[Nexus 4 General] adv1sory:
Just wondering if you have can send an update on how your phone is doing? Are the batteries keeping a charge? In regards to a back case, have you thought about sketching one up on google sketchup and sending it for 3d printing? Would make a very clean look and potentially lower the profile of the phone. You could mimic the ZeroLemon battery case in which you make a cover that goes around the whole phone to the front glass and make a slight lip that would essentially snap the 3d printed case in place. Would cost a little more for printing, but have a stock look to your home made project.
[Nexus 4 General] noowb00:
Is it possible for someone to create a 3D model of the back for this hack? I tried to make one myself but with the little to none experience of mine in modelling, I failed :P I don't have the tools to cut plastics and all sorts so I think 3D printing the back is the best solution. The idea of mimicking the battery case is good too.
[Nexus 4 General] Yuvin:
1) The NFC chip isn't in the battery in the Nexus 4, rather on the back of the case so no, the stock battery isn't needed in order to have working NFC.

2) Wireless Charging should work with a non-stock battery as long as the wireless charging circuits goes to a normal charging circuit which I think it does
[Nexus 4 General] thesebastian:
Thanks a lot. So i think i will replace My battery if a new Polarcell (or maybe Anker) replacement is out.
[Nexus 4 General] raidrom:
Doing mine today .taking the glass out sucked but I just deleted the NFC and wireless charging . I'm using straws cut down to sit on my camera and led and maybe something else for the speaker . but I'm just going to use Silicon or epoxy to build it up and then it will be kinda soft and grippy at the same time and survive a fall . I will post pictures . I had a 3.7v 2000mah battery but I found out it would over charge or not discharge enough so I went and bought a brand new s3 battery that is 3.8v 2100mah and its also thinner so it should work great thanks for the mod
[Nexus 4 General] Javier.D:
I realy love this hack, it's fantastic

[Nexus 4 General] biscuitownz:
While this will work it is not safe to use two different batteries, even though they are rated the same, one will usually be higher/lower than the other. This will eventually lead to one of the batteries being overcharged a little. I would've just bought two s3 batteries since I believe they are cheaper than the n4 battery.
[Nexus 4 General] raidrom:
I used 1 minute epoxy weld to hold the straws and battery in place.then I used black gasket maker and molded best I could and let it sit for a bit .removed the straws then let it sit over night to harden.then shaved the high spots with a razr blade .it so perfect. I can drop it from waist height and it absorbs the impact .and super grippy.I am a mechanic part time and a journeyman pipefitter so this is exactly what I need . cheers
[Nexus 4 General] raidrom:
Ohh and to the op check the mugen power app its for multiple batterys .it should work
[Nexus 4 General] toanau:
Dam bro what did u do to your phone
[Nexus 4 General] raidrom:
I like your opinion but I haven't seen yours uploaded yet ? Weird .anyways I have been using this phone like crazy all day and in never have to worry .shes not for show...is that why you have yours ? Cause its pretty?
[Nexus 4 General] Alicklee:
Wow looks like the phone got melted or something did you pack two battery's into the phone ?

How's the heat with that ?

Sent from my blazing fast nexus 4 o yeah baby this phone is awesome
[Nexus 4 General] raidrom:
I can't feel any heat at all in the back now . its great . maybe its venting better I dunno . I cut up my ballistic shell gel case to to wrap over the silicon and it looks sick. Bumpers on all corners !

This is my usage .tried downloading a ROM for 4 hours yesterday while goo was down
[Nexus 4 General] scottx .:
Really nice mod. You should use fiberglass resin to shape the cover. Could make it perfect and rock solid. (:

Good job. That screen on time is insane.
[Nexus 4 General] ponkz:
hi.. just wanna ask if i can fit Motorola EB40 3.8V Lithium Polymer 3200 mAh (RAZR MAXX) battery in nexus 4?

in single battery condition..

thanks before :D
[Nexus 4 General] raidrom:
You could .but u would run dual 3200 plus the 2100 stocker . I think the RAZR battery are really thin and long . if I had the normal RAZR battery I could have made this a lot cleaner

---------- Post added at 05:17 PM ---------- Previous post was at 05:16 PM ----------

Now that you say that .I should have .ohh well damage is done I guess
[Nexus 4 General] Alicklee:
Have you check the running temp on it?

Sent from my blazing fast nexus 4 o yeah baby this phone is awesome
[Nexus 4 General] raidrom:
Consistant 35degrees celcius ? It never gets warm ever and its plus 30 Celsius ambient now
[Nexus 4 General] myturbo1:
:eek: While creative. Yet hideous. I just don't see why more time wasn't taken to do this ?

Could have made it look pretty slick.

And no I did not do this because , well no need & ugh just look at it lol

Sorry just not going to give props where it is not needed.
[Nexus 4 General] noowb00:
Is that the CPU temperature or the exterior?
[Nexus 4 General] ziddey:
Function over form. And far more form than if I were to do it. I'd just duct tape the back and call it a day. Or maybe mod an extended battery tpu for the s3. It's pretty close, except for the cutouts/buttons.
[Nexus 4 General] ninokotur:
No. Paralel connection have same voltage no matter how many batteries you add
[Nexus 4 General] Andrew025:
You can always add more gasket maker ( at this point I don't think you need anymore though) and just sand it down to smooth it out.
[Nexus 4 General] shenery:
Added a Note 2 3100mah battery to it ;)

Will post screen on time when its had time. Just done it half an hour ago.
[Nexus 4 General] shenery:
So that's 5200mah. Is this the highest battery capacity nexus 4 in the world? :P lol

---------- Post added at 02:07 PM ---------- Previous post was at 01:35 PM ----------

Bit of a strange thing happened mate and was wondering if you had anything similar happen to yours.

I ran loads of benchmarks to see if there was a percentage stopping point like yours. It ended up going to 1% and shutting down. I then put the charger cable in turned the phone back on and the battery percentage read 24%! What's that all about? Lol
[Nexus 4 General] djsubterrain:
You guys do realise it's probably quite dangerous to stick any old battery that the phone isn't rated for in?
[Nexus 4 General] burnski:
It does exist, my mom got one for her N4. She got it at Liquidation World for $10.
[Nexus 4 General] Eldmor:
I'm pretty sure they are aware of the dangers since they are doing this.
[Nexus 4 General] supermult:
This would be such a clever mod, if it weren´t that ugly.

Seriously, why arent you replacing the whole back? Those 2 screws are actually made for that.

It´s not that hard to design a new back with solidworks and print with shapeways or some other service..

It would look so beautiful with some aluminium sheetmetal screwed onto that printed back.
[Nexus 4 General] Andrew025:
As long as it's the same voltage then there really isn't a problem.
[Nexus 4 General] djsubterrain:
It's not the voltage, your case and phone will only be rated to take so much heat, if there's 2 batteries in there then there's twice the heat so it might be a fire hazard.
[Nexus 4 General] shenery:
Well that's my 2 batteries fully charged and the voltage and temp are both fine
[Nexus 4 General] Andrew025:
There is another battery adding some heat but it's sure as hell not going to be twice the heat.
[Nexus 4 General] fahadsul3man:
nice mod , doesnt look that thick or heavy anyway i am impressed .
[Nexus 4 General] Badgie:
Just a quick warning from a technical point-of-view: putting two low internal resistance batteries in parallel can be a problem if you either deep discharge or overcharge. In effect one battery tries to charge the other (through a low resistance) and they get hot.

I don't think overcharging will be a problem as the charge circuits go to a trickle charge once the phone senses the battery is charged and deep discharging should be avoided anyway as it is not good for the life of your battery - and with twice the capacity you should be less likely to get so discharged!

Sorry if this has already been mentioned - I did scan thorough quite a bit of the thread - but it's worth repeating anyway. You don't want it to go up in flames like an iPhone 4 ;)
[Nexus 4 General] shenery:
I've been keeping a close eye on the battery temp and voltage. The voltage never goes to high and the batteries seem to stay cool.

After a 100% recharge the morning after the phones still on charge and the phone is very cool. So I assume once it gets to 100% They charging pretty much stops
[Nexus 4 General] shenery:
Check out this for some mad behaviour. Been sitting at 2% for the last hour and a half with heavy use. I've been beasting this thing all day and its still at 2%. Wonder how long it'll go for lol
[Nexus 4 General] shenery:
When you see the red step up on the graph BTW that's caused by turning the phone on and off and it thinking there's more battery than it had lol
[Nexus 4 General] shenery:
Don't know when this is going to end like haha. I will say to anyone doing this mod, it seems to take a couple of day of charges for things to kind of normalise. Yesterday the phone was shutting down because of no battery and then I turn it back on again and I have 45%. So a couple of days and a fee charges seem to sort it out I reckon ;)
[Nexus 4 General] raidrom:
I used battery widget by 3c. And in there you can custom add mah.I put 4200 and it charged and drained normally . it just sensed it and changed my phone to what it wanted
[Nexus 4 General] noowb00:
Does anyone know the between the back of the phone and the top of the frame after the glass is removed? *sorry if it sounds too complicated. English isn't my native language. I'm bad even in my own language :P* I plan to 3D print my back cover so I should at least get the right measurement. It's still in progress and it's gonna take some time so I don't want to remove my glass back just yet just to get the measurement. Thanks!
[Nexus 4 General] Andrew025:
Maybe this will help if I understand correctly.

[Nexus 4 General] shenery:
My back looks terrible lol. I have electrical tape for a phone back just now but would love to get something printed for my note 2 battery I have in mines.
[Nexus 4 General] noowb00:
Nah. It doesn't have any measurements that I needed. Thanks anyway.

Haha! I'm still designing the back. The one I'm making is for SGS3 battery. Ah, now that you mention it, is there anyone out there can provide me with the battery's dimensions? I think I can make one for the note 2's battery too. I just need the dimension.

Just a note, I'm still a student so I've a very limited time. I'm a beginner in 3D modelling and learnt by myself. Hopefully I can get it done ASAP xD
[Nexus 4 General] shenery:
That would be magic mate :) I really wouldn't know how to get measurements accurate enough for you though. Hopefully someone can help you out! Once the 3d modellings done can it then be sent to be printed somewhere?
[Nexus 4 General] noowb00:
I don't know. Depends on the service provider, I guess. The one providing me requires the object to be saved in STL format. So I'll only have to send him the file and let him do the rest.
[Nexus 4 General] shenery:
I found this site for folks in the UK. Not sure of the prices they would charge though.

http://www.3dprint-uk.co.uk/stuff-weve-done/

Imagine if this case was available to everyone. The mod is pretty simple to do and I reckon a lot more people would do it if they could get a case printed :)
[Nexus 4 General] noowb00:
Wow! That site's products look very good! Mine is not that professional, I guess. Haha! I couldn't even find myself an alternative! Dayyum.. I just wish 3D printing is widely available in my country :(

Yeah! The printed back will definitely be helpful! I'll do my best xD
[Nexus 4 General] shenery:
Good luck mate and thanks for the help! :D
[Nexus 4 General] savioleo:
information about total mah

hi sherery, could you measure the actual milliamp of the two batteries?I think you have "only" 4200 mah... why you didn't connect all battery contacts (4) but only positive and negative contacts? in this way you cant check temperature of second battery... (I suppose)

sorry for my bad english :\
[Nexus 4 General] supermult:
It wouldn´t be clever to connect all the contacts.

The battery controller or whatever is hooked up to the other end of the cables isn´t exactly expecting more than one battery, so bets are off what would happen.

But it definitely wouldn´t just display the temperature of the second battery.

It could destroy your controller if your unlucky, so don´t try it.
[Nexus 4 General] shenery:
I just followed the ops tutorial and I'm more than happy.

Getting 14 hours plus of very heavy use. I use this phone for business and it pretty much replaces my laptop so I'm happy to be getting what I'm getting :)
[Nexus 4 General] supermult:
I think you misunderstood me. There is no problem if you just wire them up parallel for the larger capacity.

But you really shouldn´t connect all 4 pins as someone suggested.
[Nexus 4 General] savioleo:
thanks supermult.... shenery can you control your total mah in full charging? I'm not convinced that the larger battery is fully charged... can you use a multimeter tester? or you can use battery monitor widget
[Nexus 4 General] shenery:
Battery monitor says its measured 2532mAh.

Seems a bit low because I feel like I'm getting a lot more out my phone now.

Is this battery monitor accurate?
[Nexus 4 General] savioleo:
i don't know... you must use a multimetric tester... :(
[Nexus 4 General] shenery:
I have one but does that not just measure voltage?
[Nexus 4 General] Andrew025:
There's no way that monitor is correct going off your usage screen shots.
[Nexus 4 General] shenery:
Yeah that's what I was thinking. Anyway I'm quite happy. Hopefully nwoob00 can sort me out with a case for it too :P

[Nexus 4 General] savioleo:
Multimetric the tester can measure the voltage, amperage and the electrical resistance (and other functions :confused: )... you must full charge the phone and setting the tester to 20 mah and connect both poles of the tester to the positive pole of the battery (poles of the tester are positive in 20A and negative in COM)... you can control how many mah do you have in full charge!

you can find a tutorial online :good:
[Nexus 4 General] shenery:
Check this out. Been off the charge for almost 12 hours. 70 odd % screen on. Look at the big drop then the high again.

Phone shut down at 0% then turned it back on and it was 50%

Sometimes it stays at 100% for hours then drops fast. Other times it drops fast to 1 or 2% the stays there for hours. Check previous screen shots.

[MDA II, XDA II, 2060 ROM Development] nargalzius:
I found ALMOST everything i needed to know in this single thread:

http://xdaforums.com/viewtopic.php?t=6694

As far as prepping the files are concerned, there's no problem . . . but flashing it is where my problem started (or wouldnt start rather).

I followed the forum, and got the announced T-Mobile ROM upgrade in the above thread, and extracted the files.

I then decrypted them using xda2nbftool. I actually used the batch scripts (which were all over the thread), that's where I found out about the decryption / modification / reencryption etc. etc. of the nbfs.

Everything was going smoothly, until I got that blasted COUNTRY ERROR thingie. And what's worse is no matter what "countryID" I put, it still gets the error. I viewed the different threads posted about the country error thing, but I dont think I have the same problem. For example, they say you can fix the country error by matching it to the CountryID of your unit (or proabably current flashed ROM) using xda2nbftool. So the syntax looks something like this:

xda2nbftool -so <ID> -v ms.nba

xda2nbftool -so <ID> -v Radio.nba

xda2nbftool -so <ID> -v nk.nba

for an O2 is probably

xda2nbftool -so O2 -v ms.nba

xda2nbftool -so O2 -v Radio.nba

xda2nbftool -so O2 -v nk.nba

Usually it just rotates between, TMOBILE, QTEK, O2, O2ASIA, etc. etc. as mentioned in the other thread (the nbfs of the official upgrade obviously start as TMOBILEs)

I've tried redoing the whole process with all these different codes (by modifying the bat files and trying out the bat files posted, but the damn error is still there.

Finally was able to spot a post about DeviceData.txt. And upon opening it, this is what I saw:

U S B 3 2 1 . 5 2 . 0 0 W W E P H 1 0 O 2 A S I A W W E 1 . 5 2 . 8 2 1 . 0 5 . 1 4

Obviously, the ID should be O2ASIA right? But i've already tried O2ASIA and I still get the country error. I wonder why it wont work. last thing I suspect would be the PH10, cuz i checked my unit via device information and it was listed as "PH10B" (but the DeviceData.txt says PH10 only)

Basically that's my dilemma. . . as far as modifying the extrom etc. etc. I seem to be getting it already, only thing to do is figure out how to make the flashing WORK.

That's it for now i guess. Hope someone can help me out
[MDA II, XDA II, 2060 ROM Development] Jos:
For an O2ASIA, you should use O2 and not O2ASIA.

Grtz,

Jos
[MDA II, XDA II, 2060 ROM Development] nargalzius:
OH ic, i could've sworn it didnt work with O2

it seems to accept it no :)

so last question i guess would be as of today, is this the newest rom upgrade available? (aside from SE) or should i wait for that

and lastly i should have no problems with a Himalaya regarding the radio right since it's a triband phone (so it should still work with my carrier)
[MDA II, XDA II, 2060 ROM Development] pochreyes:
nargalzuis, I recently upgraded to the latest t-mobile rom and it works fine...
[MDA II, XDA II, 2060 ROM Development] Jos:
It's the last update, should work with any provider.
