I am going on a flight in two parts with an 8 hour wait in the middle - then onto a train for another four hours which is 5 hours after my flight arrives.
When I am waiting I am intending to access the net, and also use the phone to play films on the flights/train.
I had thought about getting a high capacity battery to use with the standard one, but I guess run times would go beyond their capacities as the total usage runs to over 24 hours even without delays.
I had seen solar chargers on ebay - but although I could probably use it on a train - i doubt if it could be used on a flight - but guess it could be fairly useful for camping etc.
I also saw a "powerpack" that charged USB devices by using 4 standard AA batteries, and thought this would be a better bet, as I am likely to be able to buy them at airports and stations etc so I can keep the phone running.
Any suggestions of the best way to do this - or errors in my idea?
With an 8 hour stopover, I'm sure you can find somewhere in the airport to re-charge without worrying about batteries.
How long are the flights ?
Maybe your flight will have power ports as well? I know some do, although typically not in economy, where I travel, whence one must "jack" into the bio-electrical discharges of our own thought processes to merely heat "dinner".
You can also get those new fangled ipod charging things as well. Charge em up overnight, then use them to recharge the ipod or any other usb/firewire device on the go. Might help. Can't remember where I saw it.

1) Can you be specific about the airport(s) and train services involved?
2) How much power-related gear are you prepared to carry?
It is an ex soviet asian and eastern european air services and an ex soviet asian train.
It is likely there will be people carrying chickens with them on the asian ones before you start thinking technology!!
Everything needs to fit in a rucksack and hand luggage that gets carried in the rucksack once i come off the planes.
I start in heathrow - so everything should be OK there.

Possibly with JFK the worst premier airport in the world.
Perhaps you should look at renewable energy sources. I haven't heard anything about power from chicken guano but I'm sure someone has a theory ;-)

havent used one on my wizard but my dad uses one on his mitac and gets 2 full charges out of a set of batteries.
have a look on ebay for xda battery extender there are some more.
I use the AA Battery method when I travel to china. On a good set of batteries, I get about 3-4 full charges. But I usually only use it to top off my battery when I am on the bus or train. It's nice and small, and the batteries you can buy anywhere, it's awsome.....
I reviewed Gomadic's road warrior kit on pocketnow.com here. It has a battery extender, which can also be purchased separately for $19.95. It works very well and with their swappable tips (TipExchange) can be used with many mobile devices.[/url]

are you coming to Moldova?
Further over - "Chernozhopayalandii" - I always though the station in Kishinev looked pretty modern for one where you need to walk over the rails.
I heard the train no longer runs to Tiraspol now though, or is it all of Transnistria?
I got a 4x AA battery extender on Ebay. It works pretty well and I guess the batteries are available almost anywhere.
Does anyone know if there is a USB extension cable that would match the charger and the phone?
Also I got a 6v rechargeable battery out a burgar alarm I was removing (from a friends house- honest!!!) which is about 7cm x 10cm x 15cm and was rated in double figures Ah. I guess this could be the start of the ultimate travel charger/extender.
Has anyone tried this http://www.realtechnews.com/posts/3169 ?
solar charger
The solution here is a solar charger. I got one of a ebay that is strong enough on a sunny day that you can run the device without the battery depleting. It's about as big as a CD case with 2 cd's next to eachother. It has a zigarette lighter jack so you can use your car charger.
The charger worked unbelievably well. It had a small LED that got dimmer as the power was used up, which without there was no way of saying if it was still putting power into the phone.
I never used it to charge the phone as such as the phone was in my belt pouch - but plugged it in when I was using it so the power was kept at full all the time.
The solar charger someone mentioned would not really have been useful due to the low light levels inside the airport and after dark on the train, and I think the airline staff would have been looking a bit worried when someone tried to attach something against a window on a flying plane, but obviously would have been good for something like camping in the middle of nowhere where there were no power supply or shops.
Regarding the airline headset charger - I would guess these would run on a lowish voltage (3v i would guess without checking) so may not give the phone that good a charge.
I got it here...

Having tried just about everything to prolong the life of the battery on my Desire HD, I think that I have, at last, found a real solution.
I did not like the idea of buying a spare battery mainly due to the flimsy battery compartment on the phone and the thought of constantly swapping batteries. Swapping batteries would also involve switching off the phone and losing data (for example, if you are using GPS to track your movements).
I have tried lots of software solutions, most of which help to give me an hour or two of extra life. My favourite software solution is Juice Defender, which works well within the limits of HTC's awful battery.
Someone on another thread recommended the TechNet external charger, which packs a 5,000ma charge - enough for four full recharges of the HD phone. It plugs into the micro USB port on the phone and charges the phone as though it is connected to the power supply. It hot-charges, which means you don't need to swap batteries or switch off the phone. The device comes with lots of adaptors to charge lots of different devices. There is also an 11,000ma version... enough for 10 recharges.
Available on Amazon:
http://www.amazon.co.uk/gp/product/B000NDQ92W/ref=oss_product
It also looks good and comes with a travel pouch and is smaller than the HD phone itself so slips into a bag without a problem.
Looks promising. Thanks for the info bobby!
I purchased this before I went back to nz for Xmas. Well worth the purchase, has saved me several times. One thing to be mindful of is that if you accidentally turn it on without realising, the battery will drain, even if its not charging anything.
Sent from my Desire HD using XDA App
Is the battery really that awful? I can use the phone for 24hrs (including stand-by time, 14-16hrshrs of usage time) with wifi, 3g constantly on until I need a charge.
Which is really more then enough time for me in between charges, unless you go on trip for days without access to a computer or an wall socket.
Its nice to have a phone which last for days like the old days, but it really has no inconvenience charging it once a day, right?
+1 , left my phone in work the other day after reasonable useage in the time I was in work 0900-2000, came in the following morning , to find 13% charge remaining and that was in-spite of my alarm going off
I find that if you put your phone in power saving mode, even the remaining 10% can last you for almost a day.
Its quite useful if you know you gonna leave ur phone for a period of time.
Actually it would be quite useful to have a toggle widget to do that on ur home screen instead letting it activating itself below a set percentage. Is there any?
Howdy,
I was so frustrated with the battery usage I nearly ditched the phone. I decided to apply a different rom after reading and considering many posted here I went with Coredroid, which I downloaded from this site. (had the original vodafone rom) Great support and documentation and tons of help if it goes south.
I can say as of now my phone is 5 times at least faster and the battery life has extended 300%.
When you check battery usage the I found the number one battery killer is Display. With Coredroid its about the 5th item on the list. Wireless and bluetooth and the biggest now (if you can call them real big) but they are easy to turn on/off.
I was very nervous about a custom rom but I needed something. I can only recommend you look at other roms apart from you stock one -Im assuming. (Im not sure what warranty etc rules are gone, personally I don't care)
Cheers

Yes, that was me, with the external battery pack/charger
Well, it's a heavy phone already, a huge screen to light up and render -it's pretty clear where the power is needed. But would the bulk associated with another 400mah really have tipped the DHD over the edge?
Anyway, it's designed now, and nothing can be done about that. I'm quite happy with it lasting until the night for normal/heavy usage (about 16 hours) - with it's out-of-the-box form factor.
And for those occasions when I'm using GPS tracking apps out in the open for 5-6 hours, broadcasting my location to a website, hooking it up to the external pack (mine is in fact a New Trent one, 5000mah) means it won't drain unexpectedly. That is, with 5000+1260mah combined!
The battery pack provides a "full" charge in about 2 hours, that is just like a mains charger (it is rated up to 1amp output, providing of course whatever amperage the device pulls).
That pack might be a solution for the battery problem, but I still don't think it's enough. I don't think that you should have to buy a portable power pack just for your phone battery to last. The whole point of mobile phones is that you have access to a medium of communication in a remote location. By not making the battery life long on a phone, I reckon HTC are actually limiting its main use. But that's just my 2 cents, and it does depend on how people like to use their phones.
5000 mah is not enough, why not make it larger
Thanks for the info.

You must love the 1240Ma battery that comes with the phone.
You've enabled USB Debugging, yeah? I get 2 days, and I work in the middle of nowhere. The phone polls for a new cell constantly while I'm in my office.
If signal is good in your area, tell the phone to use GSM or WCDMA exclusively. Otherwise it will switch to whichever has the better signal, which can be problematic is you're in an area with good / poor coverage of both technologies.
I think the polling thing might be a big battery killer. I shall try that.
I friend of mine in the office, use to have a Sony smart phone that barely lasted a day and thats on standby. He ditched that for a DHD. His battery now lasts 4 days plus, with minmal use! Mine on ther other hand with minimal use can give 2days at most.
The difference is that he is on ORANGE and I am on T-Mobile. It must be down to signal strength because he use to be on THREE and the signal strength was very poor at his home location.
BTW, I find that Juice Defender does help and switiching off Flash in the browser.
This charger and the USB-Batteries are the best inventions ever
It would be great if this phone got accessory support like the fruit phone does. An extended battery case would be the most optimal solution to this problem but I haven't heard of any out there yet
P.S send me a PM if anyone finds an external battery case
how is it compare to eneloop 5000mah?
Ah! I need that one for when i go camping
I'm truly upset about this, because I think this phone is almost marvellous. But in the two weeks I've had it a few horrible problems have emerged, and I can't find solutions.
If anyone can help (REALLY help), I'd be very grateful.
So. Here I go:
1) The antennae (or whatever). I'm sitting here, in my study, which is in my garden, about 60 feet from the house. In the house (right on the kitchen window) I have a wi-fi AP, to boost the signal. In my study I have : a PS3; a desktop PC; a (Samsung) netbook; an iPhone 3gs; an HTC TP2, and the SGS2. Every single device has a good-to-excellent connection. Except the SGS2. Which says "poor", except that most of the time it can't get a signal at all - so that's not even as good as "poor";
2) I took a friend to hospital today. There were three of us in the waiting room. The SGS2 had no (phone) reception. The others did;
3) On the way to the hospital I needed to use Google Nav. I plugged the SGS2 into my car charger. It didn't charge. I've since tried three different chargers (and no, they weren't from Poundland). Same thing. The SGS2 just won't charge in my car if it needs plenty of juice. I've been trawling the webs and this seems to be a common issue - but nobody has a definite answer. I was about to spring for an official Sammy charger, but nobody seems to know for sure if it'll do the trick.
4) The sound isn't great, either in fidelity (and I'm using Shure SE530s, just so you know I care about good sound) or volume. It's tolerable, but only that. No comparison to my little Sansa clip, or even (I hate to say) the 3GS;
5) (though not as much as some, it would seem) the battery life is a bit meh. And I'm not a heavy user.
I read many people complaining about silly little things. A lot of them are down to software or simple ignorance. But a super-smartphone that has poor connectivity and can't be used as a satnav (whilst simultaneously charging). Well, I'm sorry, but...
As I said at the top, I'm genuinely miserable about this. I really, really thought that this was the Smartphone to Rule Them All.
And, again, if anyone can offer me hope that things will get better, please do. Sadly, I think I'll be going back to separate gadgets to fulfill my needs. A phone that works as a phone (and maybe a diary); a satnav that charges in the car; a music player that sounds good. Etc, etc.
ive got a crappy 8-in-1 car charger works fine.
I have none of the problems you said in your post so maybe you just got a **** phone, maybe return it for another.

Do you mean it works fine when you're also using satnav? Because there seem to be many, many people whose SGS2 won't charge when running satnav.
That's what I was thinking maybe one problem is tolerable but all those things you mentioned I would've been took that boy back for a swap out. Unless you brought it online.

Yes, maybe I have a "**** phone". Then again, lots of people seem to be having similar issues. Do you think there was a bad batch? Can you charge the phone in-car whilst using satnav? Is your wifi strength as good as your other devices?
I think I may call Vodafone now and see if a replacement helps. That's if they'll still swap it out.
If you arent happy with the phone, return it/exchange it.
simple as.
As for advice, read the threads.
I also have none of the problems you are suffering. My wifi works as well as any other device I have had. Phone signal is better on the same network a my htc desire. Sound quality is better than my desire. Battery life is so far pretty good and will get better with use and even better once 2.3.4 comes out very soon.
As for your charging issues while using nav this is a common thing with cheap chargers, you might not have got it from poundland but its just not supplying enough juice. Had exactly the same problem when I first got my desire over a year ago, ended up modifying my car charger by soldering the data wires together to force it to max out its current output. Use that same charger for my sg2.
The only problem ive had is the car charger one which i didnt realise untill yesterday. All your other problems dont exist on my phone so mabey exchange it

With reference to the car charger problem while using satnav look at http://forum.xda-developers.com/showthread.php?t=670702&highlight=car+charger&page=2
Thats the thread from the HTC desire doing the exact same thing. If your charger is 1000ma you should be able to mod it or a cable so that it will happily charge your sg2, if not make sure the next one you buy can supply enough current.

The phone seems to have love/hate relationships with different routers. In the way I use it, it works as well as a G2 and G2X connecting in the same locations. I have a beast of a router and what I tend to connect to (airports, hotels, airplanes) have better than average equipment. People have had some luck by replacing their router. If it's software, the imminent 2.3.4. update may help.

There have been various postings on this. People with issues popped another carriers SIM in the phone and in a lot of cases the problem went away. Try replacing your SIM. If the phone's just not good reception wise in the areas you travel or on the network you use you may have to return it.
3) The SGS2 just won't charge in my car if it needs plenty of juice.

I've been using the LG charger from my G2X and it keeps the phone battery-positive using Nav and Bluetooth audio streaming. There's a thread dedicated to this somewhere, do a search.

I have the same headphones and am quite pleased with the output. I also stream Bluetooth in my car and the phone easily outperforms the G2 and G2X. There's a long thread discussing audio and a couple of folks using Shure's were getting different results. It might be a hardware issue with your particular phone. But, judging audio is subjective so what's good for me may not be for you.
5) (though not as much as some, it would seem) the battery life is a bit meh. And I'm not a heavy user.
Click to expand...
Click to collapse
There's an issue with the suspend process in 2.3.3. that drains the battery at idle. The imminent 2.3.4. update should correct this.
I also noted poor wifi signal. Changed my router to a better one and it fixed the issue, however I still have problems in my travels ( hotels, bars, airports ).
Regrading the navigation, I did a total of 2500km ( 2 long trips of 900 km each + other small and medium trips ) with the phone being in nav mode. I had the battery issue you described due to overheating, but as soon as I protected the phone from direct sunlight ( a small piece of paper over it ) or kept a small flow of air on it ( placed it near the AC vent and redirected the flow twoards it ) the issue got resolved. Using a 500mA car USB charger my phone stays cool at about 36 degrees C and the battery gets +1% every few mins ( navigation + wifi tethering on with Kies over wifi activated ). In regards to the software, I mainly use iGo or Copilot.
So solution: make sure you have a little airflow on your phone and a little space between the back of the phone and the phone holder. Satisfy these 2 conditions and you will eliminate the charging problems.

Thanks for that, mate. Just to say: my phone "says" it's charging in the car; but when I do a drive with the satnav, then unplug the phone, it hasn't actually been charging. Again, I'm not the only one with this problem (or feature).

I may buy the official Samsung charger but there are people elsewhere who've had no luck with that.

Sat nav will max out the phones power draw, reducing charging to a trickle, it's just a case of taking out almost as much as you are putting in.
I find from using wifi analyser on a few devices what Samsung call two bars in signal strength, most other devices call 3.
Not sure why that is.

Well, I'm sorry, but I find it completely normal to say that some charger we got off eBay, third-party probably that's not even a brand name, isn't capable of feeding our next gen device that has not only a dual core processor, the most ram on the market on any phone, a GIANT screen, not enough dissipation space (for heat) to keep it thin as thin as thin. I'm worried about battery life as well, but oh well. It's the price we have to pay! hehe.

Sorry to hear this...but the problem isn't the "GS2" it's your specific GS2. The vast majority of users have maybe one of your problems, which either fixes it self, or fixed through an update. There are even more, who don't even have any of those problems.
I think that you have a faulty unit and if you are upset, get a replacement, because the GSII is one fine device and capable of doing all you need it to do.
Please read my last post for the correct answer to the satnav power supply problem. It has nothing to do with ventilation and everything to do with the type of charger you are using.
You could buy a 1000ma very expensive charger and it still might not charge your phone when under extreme load. Some chargers will only supply 500ma as that is the max that a usb socket on your motherboard is supposed to supply. Doing the mod I described earlier solves this.

I only make sure that the AC is blowing through the defrost holes also... the airflow required is minimum. This applies to all phones and even other dark colored gps devices I owned before... In the summer, the sun heats up the phone and/or gps device a lot. As a test, try leaving the phone in the cradle in the car ( under direct sunlight ) for an hour. The phone can be kept at idle, or even closed. It will heat up a lot... I remember I threw away a compact photo camera cause I forgot it on the dashboard for a day, in the summer (it was pretty much melted and very deformed)...
So a bit of common sense will fix the temperature issues... the charging problems appear due to the temperature issues. If the batter temp is above 50 degrees it will stop charging. When you keep the batter under 50 degrees, a 500mA decent charger will be more than enough to keep the phone running and slowly charge the battery.

If you're about to ask me if I've considered an ssd instead, know this. I may be an idiot, but I'm not that stupid. My IQ may be around 30 or so, but It's just high enough for me to figure out that an ssd is a much better option than an hdd. Jesus christ, stop asking this question already. The reason I've opted to put in an hdd instead of an ssd is because of cost. It cost me about $50 to for a 750GB hdd. An ssd with the same capacity will cost an arm and a leg. Go ahead and look that up.
So, please, if you're going to suggest I use an ssd, consider reading the above paragraph. And if you're going to email me telling me what an idiot I am for using an hdd instead of an ssd (like that turd a couple days ago), then also consider pushing the donate button right below my name so I have enough money to buy an ssd with comparative capacity. Goodness...
People, just because this is the internet doesn't mean everyone else beside you have an IQ of a potato. Get over yourself already.
****************************************************************************************************************************
I'm making a new thread because this is an entirely different mod than the other one.
So, I've added 2 more battery cells parallel to the other ones, doubling the capacity while maintaining the voltage. in addition, I've also added a 750 GB HDD.
Unlike the other mod, which suffered no deformation, there is a little bit of deformation in this mod. I can still close the netbook form. And if you look, you can see the curvature of the keyboard dock. It's not very noticeable, but if you know it's there you can definitely see it. Here are the pictures. I am currently testing out the battery capacity to see if it's really doubled like it's suppose to. We'll see, I guess.
By the way, while I am very happy with my result, despite the slight deformity to my dock, I definitely recommend against this for anyone else.
Speaking of which, how do I recalibrate the battery indicator? Looks like it's dropping at exactly the same speed as before.

It only affects the tablet battery. I can't get a definite answer from all my searches how to recalibrate the dock battery.
Aw, the deformation is a no in my book, but I think the mods themselves are awesome. If I tried this, I think I'd go for more batteries because I can't find enough stuff to fill my 32g usd cards anyway.. (or a secret compartment storing unmentionables).

I don't blame you. The deformation is hardly noticeable, but it is there. I'm actually happy with this setup. The slight deformation doesn't bother me. As long as I can still close the netbook form.

If the method is different, could you post a tutorial? I think I might attempt it after I find out if I got into any good grad programs..

Both, actually. Before, I was both stumbling around blind and doing things in not so efficient and safe way. My soldering skills have improved greatly and I have also refined my procedure to involve no risk at all. It's all in the wrist, man.

Uh... no. This mod voids your warranty. I will take my methods with me to the grave.
PS - Isn't it obvious from the photos?
Added by edit.
Ok, my conscience got the better of me. There is something I left out of the photos. A key ingredient to making this whole mod work. Without this very simple but critical thing that is covered up by other components in the dock, the mod might as well be a piece of brick. It took thousands of hours and millions of dollars of research to figure out this one small piece of modification to make the whole thing work. My dock was sitting there for almost a month dead before I brought it back to life with this thing I'm speaking of.
In other words, don't try this. Trust me, you'll regret it not knowing what this thing I'm talking about is. It took me a whole month to figure out this thing. Thinking back, my goodness, the solution was so simple. And yet it took me a whole month to solve it.
Added by edit again.
I just figured out how to make the deformation go away. Damn, why didn't I think of this before. I'm too lazy now to open it up and apply the fix.
Are you not worried about charging two separate battery cells without a load balancing charger? At least from the RC world, this is a big negative. Fire can be no fun.

Exactly why I just took it apart again to redo my setup. Will update on my progress later.
Ho ho ho, just figured out a safe way to connect the bats. Too late now. Will do it tomorrow.

Exactly right, lion/lipo batteries need to be balanced in charge otherwise you will burn out the batteries and in extreme cases, BURN the batteries.
Having said that, many/most of the lipo batteries I have worked with in electronics have balancing circuits per "cell" so in reality you can simply add them like any battery and they take care of themselves. If lipo batteries were purchased without that circuit, then they are very cheap to buy and add as well.
I havent cracked the transformer, and dont plan to because the stock battery life is plenty for me; however, I have increased the battery capacity on several laptops, and other types of devices, and the first key is to ensure the cells are balanced before connecting them together, then ensuring you have a balancing circuit to EACH cell otherwise over time they will come out of balance (normal use and internal resistance). Once you have done those two things, you can connect them and use them.
Now, the other point is the meters. I have no idea about the transformer but most battery meters work simply on the voltage on the batteries and assume the discharge in a linear fashion. This is rarely true for batteries, but it is simple, cheap and gives you an idea about how much power you have left. Sometimes this is error is covered by software that "maps" the battery discharge rate and gives you a "real" battery left level. So to the point of all that paragraph, once you balance the batteries, connect them and run through a few full charge/discharge cycles, you will likely find that the meter will catch up.
A point of caution, the word "cell" does not refer to a nicely packaged lipo battery with two wires. A cell is a single constructed unit that is usually 3.7v in the lipo world (different chemistries of batteries will have different voltages). If you added a pair of 3.7v (1s1p) batteries in parellel with a pair of 7v batteries (2s1p) you could really confuse the battery meters.
Enjoy the mod, I love reading about them..

Interesting stuff, makes me wish I had the tools (especially a soldering iron) and more desk space, just to see what experiments could be had with this device.

I just redid the mod. Unfortunately, it was 3am and I forgot to take pictures before I closed up the dock. But basically what I did was charged both batteries up to 100% and connected them in parallel as is with their balancing circuits. Before, I took the cells out and added them to the circuit of the other one. This time I kept the circuits and added the circuits together.
It seems to work. The new battery pack is recognized. We'll see what happens later.
Here is a picture to give you an idea.

So anyone else thinking what im thinking HARD MODS baby. im a anti-government privacy pirate android junkie so naturally i take the camera modules out and im working on the GPS modules but i hav an idea to hav 2 batterys present in the phone now ive alrdy figured out how to mak the room but i need help wit the proper wiring set up. note in order to mak room the wireless copper charging coil will need to b removed "MAYBE" and the originally backin will need a cut out to accommodate the second battery as well as the internal frame<---thats 4 sure then simply apply a slickwrap to cover up
ADDed info: my main concern is the voltage from 2 batterys i know enough that doubling the voltage is bad [rlly bad lol, kill main board etc kinda bad] but doubling the battery capacity from 3220mah to 6440mah isnt CONCERN FIXED ONLY A PROBLEM IF CONNECTED IN SERIES NOT WEN IN PARALLEL ALSO VOLTAGE ON BOTH BATTERIES NEEDS TO B DAM NEAR THE SAME DEAD NUTS THE SAME
Dual battery mods completed safely and successfully on:
nexus 4 - https://forum.xda-developers.com/nexus-4/general/4200mah-nexus-4-internal-battery-t2239829
samsung s3 - https://forum.xda-developers.com/galaxy-s3/accessories/samsung-4200mah-battery-mod-t1800177
Next issue is a minor soft mod which we'll need insight on the software file on the device the lists the 3220mah will need to b changed these/thise file could b used to calculate the correct battery percent to b shown in status bar or battery stat page in settings IF WE'RE GONNA DO THIS LETS DO IT 169% BABY
so a OEM battery is thin and cheap enough that i mite add 2 batteries instead, 3 in total

Just a thought, but couldn't you just remove the camera.apks and any files related to GPS? I would imagine that if the files are either not present or disabled that relate to camera and GPS, I would imagine if those things do not work on your phone then big G would not be able to access them either as the files needed are present... hope this makes sense. That way no hardware removal needed.
That being said... an extra battery would be cool

agreed but ive done both alrdy to b safe, they could push/sideload wirelessly the files needed to use camera modules my main focus is the dual battery mod any input on the wiring set up unfortunately i dont no much bout batterys to pull this off
as of now with almst perfect conditions i can get round 8hrs SOT but i need more, mmmm battery whore, 8hrs SOT wit 23hrs phone idle, heavy use overclocked games PSP emulater 2.5hrs SOT wit 18hrs phone idle and min. use 3.5hrs SOT 7-9days phone idle not bad but i need better dual better

Not really too much. As all the fuctionality is still there. The only thing missing is the UI. You could still activate it by command line. Couldnt snap a pic or anything but you could activate the camera and then stream it to where ever if there is a data connection.

Not at all. There are some that really do think that the Government is too wrapped up in our lives. There are also companies that require your cell phone to not have a camera.
Too many people these days have no idea about privacy. They have freely given it up. It is good to see someone that looks around at the world he lives in.
Why do you think the government cares about spying on you, specifically? You sound intelligent, did you discover something you weren't supposed to? The government probably isn't the entity you should be worrying about. Walmart secretly owns Google. They are trying to achieve consumer omnipotence. They watch and listen to everything you do and say just so they know what products to sell you.
If you are this worried about it, you should know that at any point, they could send a signal to your phone causing it to go into "kill mode". The battery will send out a high intensity discharge of 50amps causing your heart to stop. If you are lucky enough to survive this, the battery explodes in an attempt to destroy the evidence. They haven't got the system working perfectly yet, that's why we saw all those note 7s blowing up.
They can send the kill mode signal to any phone, even non smart phones, so you probably shouldn't carry a phone. Or just buy the products they advertise to appease them. Your choice, I've probably said too much.

As for me. IT is part of the job. I work in many places that requires them to check on you from time to time. Heck the types of places I work even can dictate what type of device you can own and have with you. You also have to understand that there are things you can do to put yourself on thier watch list. It really isnt to hard to do really.
I perfect example is I was helping my son with a presentation on religious history and after downloading the Quran and was questioned about it less then a week later

What else were you searching for, roofing nails(for that pesky leak) and pressure cookers (I have tomatoes to can, OK)?
All kidding aside, the amount of information out there on your average cell user is insane. Even before smartphones they could obtain a massive amount of information just from metadata.
I totally have respect for OP. Thanks for taking this thing apart, seeing how it ticks and deciding to make it tick different. Kudos on your cajones, sir!

Camera: put a piece of electrical tape over the lens or buy a pack of colored round stickers from the dollar tree and put one of the black ones over the lens. OR just take black paint, black marker etc and black it out
Tracking: turn off GPS, uninstall any and all apps

You really dont think that turning off GPS on a device with the FEMA chip in it does any good do you?
Sometimes it is amazing how much people really dont know goes on in the world.

Just glad we're not down that far on the 1984 road as you guys are over there (just yet). But FEMA chip? Any serious sources for that?
And questioning because of Quran searches? That PATRIOT act sure messed up something about your democracy if that is even remotely true.

You have no idea. That act was the dumbest thing people did and all because of the heat of the moment. They didnt read it and then got mad about it when they saw they gave the gov the right to monitor them.
You have not been around for long huh? The FEMA chip has been in devices for years. Search around. There are plenty of talks about it. Not sure if the FCC blueprints are still on the site but worth a look. There was a huge deal about it as it showed at one time to be connected to the mic and GPS moduals. Mind you this only applies to the US. This is part of the reason why our devs here prefer to get the EU models of devices.

actually nope jus dont thinks its rite that ppl can c where i am and what im doin simply as that
For the batteries, connect them in parallel. + to +, - to -. I've done it on other phones and it works fine. I'm not sure how it would react with quickcharge, but I think it would be fine. I've actually been considering doing it on this phone as my battery is starting to show it's age. If I do, I will 3D print a frame and soft outer case much like how the ZeroLemon battery kit for the Note 3 was done.
Since you seem unsure about parallel vs series wiring, please read up on proper handling for lipo cells. I would not want to see anyone make their own Note 7 firebomb.
If you put the charging coil behind a battery, it won't work. Might as well save space and remove it. You might be able to relocate it to the outside battery.
If you are really concerned about GPS and camera, you should disconnect them or otherwise damage them. Can't do much about the mic though. If the GPS is marked, you can probably find a datasheet for it, then just cut the trace for power. Practice on an old PCB if you haven't done this before, you can cause serious damage to the board if you do it wrong. If a state level actor or good hacker is involved, they can still get rough location via cell towers, wifi IDs, and Stingrays. If you are really concerned, you should probably not carry a phone at all, or keep a metalized pouch with you to put it in (faraday cage).
After Snowden, and having worked in some environments, I get where people are coming from with it. In some cases it's not that people are doing anything wrong, they just want to have more control over their privacy. Not everyone wants their lives all over the internet, and there's nothing wrong with that.

"parallel" self explanatory
my question is where to put the bridge to hav both batteries usable do i bridge the batteries together which i think would create a charging loop [charging battery 1 would then charge battery 2 until both full] then wen disconnected the phone would still show charging state
[i think] until battery 2 was depleted
i could b wrong now what bout the voltage comin from 2 batteries the battery outputs 3.7v give or tak now doubling that 7.4v should fry the voltage regulators if any present no?

That's not how it works. Batteries in parallel charge and discharge together. The voltage does not change. Batteries in series adds the voltages together. In parallel the voltage is the same but the current and capacity go up.
To the phone, batteries in parallel look like one battery. They do self-regulate/charge against each other, but the phone can't see that. For safety reasons, you need to make sure the voltage of the two batteries is similar, within about 0.1 volts, before connecting them. If you connected a fully charged battery to an empty one, the worst case, the full battery would dump power into the empty one trying to fill it to the same voltage. This would likely destroy the empty battery as it would not be able to handle a charge rate that high. It might also damage the full one, as cell phone batteries are not designed for high current discharge.
