Any third party extended battery options for the S7? I prefer the slim version if possible.
Sent from my SGH-T849 using XDA App
I rigged up a battery pack using 4 rechargeable Energizer AAA's and just plug it into the DC power socket and double-sided taped it to the back of the unit
I imagine I could use some left over spare Li-Ion batteries from other phones though.
UPDATE: someone asked how
STEP 1: Buy something similar to this http://www.littlebirdelectronics.com/products/4%2dAAA-Battery-Holder.html
STEP 2: Buy a male plug that fits the female power socket on the S7 Like this but the correct size http://www.littlebirdelectronics.com/products/1.3MM-PLUG%2d2.5MM-SOCKET-DC-ADAPTOR.html
STEP 3: Solder them together so that the + and - charge come out of the same wires as the wall-charger
STEP 4: Plug in batteries
If this looks/sounds difficult, don't even attempt it, you WILL break your tablet.
Since the original battery do last too long, i found this 2 option that i think that work with S7:
Good price and free shipping
lol i cant post links yet, sorry guys...
here goes the links for the battery extender....

Nice guys! I was searching for an internal battery solution.
These battery packs look nice but be carefull, the output is only 500 mA. The S7 charger is a 2amp output charger. I'm not sure how well it will run on a lower input.

The DC pack will only feed what the unit draws, and I doubt very much that it draws the entire 2000mA.
I have rigged up a USB charging cable for myself, USB pumps out 5v at 500mA max per port (I'm only using 1) and it charges a little slower than from the wall, depending on which computer I'm charging from, but apart from that it works great still and I can use the same cable to charge from other USB-charging devices like the one I have in my car.
The 500mA output will just mean it charges slower, and seeing how it's only a battery extender (IE, the oem battery is still required) and not a charging solution (the S7 can run without the battery off only the charge from the wall), the charge provided will be fine for extending the battery life.

500mAh as supplied by standard USB will charge but as you say only slowly.
It will not start a charge if the battery has been allowed to drop too low. That's common with all Lion batteries and is why you get a high current wall charger to do the job.
If you are using the device at the same time (and depending on the functions in use and the state of charge of the battery) you will definately struggle with any positive charge and will experience heat build up in the USB port, cable and device so be carefull!
If you are also using the device as a phone and get a call there will be an extra high peak current draw that has to be contended with and that complicates things further.
With all the tests that I have done allong these lines 1000mAh is a bare minimum to cope with eventualities and even then it's borderline.
I have blown car adapter fuses and had low current phone chargers get really hot.
I now only use 2000mAH rated chargers.
Are there any? I would really want to have a battery that could last at least 6 hrs... Any suggestions?

Energizer XPAL XP18000
That will give you about an extra 12-18 hours,
But no internal battery larger than standard. Why would you want one when the external packs are usable with any device and don't become redundant when you upgrade to a different model?
I made such a battery of two packages of Chinese Tablet battery voltage of 7.4V LiJon / 1500mAh connected in series and used a converter on the circuit LM2576 (with car charger navigation) [//chomikuj.pl/wibi) -> Huawei Ideos S7/Dodatkowa bateria]. This additional charger to recharge your battery voltage 8.4V. Pictures and diagrams from the following link will explain everything.
Using a New Trent External charger I noticed that the phone was still losing power, just at a way slower rate than without it charging. Phone showed charging. I was using netflix via 3g at the time. Would this be expected? Not super worried as the battery charges just fine when screen is off and not in use.
How many amp output is that charger??
My phone can't keep up with the charge if I'm veiwing a movie using HDMI unless I run incredible kernel with fastcharge enabled.
7000mAh. Think 1V output?
IIRC, the stock A/C charger is 1 amp.
A lot of aftermarket chargers do not have the balls to charge the Rezound.
you may need to modify a usb cable to short the Data wires to get the full charging potential out of it.
or try one of these cables from amazon:

Does this cable work for sure with the rezound??
I don't need it right now with the incredicontrol running, but I ordered it just as a handy thing to have.
My new Trent works pretty well, but I wouldn't expect it to keep up with streaming vids. I found that it gives a charge to the idle phone at about 800mA, which is about the same as the stock wall charger.
Pick up battery monitor widget and you can track your plus and minus usage pretty well to decide if everything seems OK.

Well, I'll answer my own question. The cable definitely DOES NOT force higher charging at least when using an HDMI adaptor.
If I use Incredikernel with fast charging enabled with Incredicontrol, it will actually GAIN charge while playing a full length movie through HDMI.
This morning, I flashed back to dsb 1.3 with no frills cpu control & hooked up the new cable for charging. I started with a 100% charged battery & after playing a 1 hour DVD RIP from my card, it was down to 89% charged. Using Incredicontrol, during the exact same test the battery still read 100% at the end.
Thanks for your results jmorton10. Good to know. I wonder if it's the connections inside the HDMI adapter messing with it.
Not sure why HTC can't just get this right to always pull the max possible from whatever it's hooked into!

My understanding is because the MHL adapter needs the USB data pins to work properly and they can't be shorted out as mentioned above, the phone thinks it's on a USB connection and limits it's current draw to 500mA.

That is definitely the problem, the battery monitor widget claims it is charging from USB even though it is plugged directly into an A/C charger.
I guess I will be flashing back to Incredikernel/Incredicontrol tonight. I do like dsb kernel slightly better as it never freezes/bootloops etc. ever on that kernel. It does stop responding occasionally on IC (requiring a battery pull) although it doesn't happen very often.
The Rezound complies with the USB charging specification. If your power source isn't compliant, it won't draw more that 500 mA (and probably less if USB doesn't enumerate, but I haven't checked). That's what the "short the USB data pins" thing is all about. Earlier USB charging spec said they should be shorted, the latest says 200 ohms. Any "USB charger" which doesn't do that isn't compliant, and shouldn't be sold as USB-anything, because it doesn't follow the USB spec. Return it to where you got it, and complain (loudly).
Regardless of how much power a charger can deliver, even if it meets spec you won't see more than about 800 mA go into the battery. There's a limit to how much current both the connector and the battery can safely handle, and the phone takes that into consideration.
Remember, the mA reported by utilities is (always?) what's going in/out of the battery. The charger would be delivering more than that (e.g. 800 mA into the battery, plus 400 mA to power a phone doing video streaming, etc.). AIR, the micro USB connector is limited to ~1500 mA, and I've never seen a battery charge at much more than 800, as reported by the kernel. Conversely, when charging from a non-USB charging spec compliant port, the phone won't draw more than ~500 mA from the port, and the battery only gets what's left after subtracting what's needed to run the phone.
Another thing which can affect charging is the cable. If you have a long USB cable using 28 gauge wire, there will be a significant voltage drop across it. USB specs say the voltage should be between 4.75 and 5.25 V, and Android seems to limit the charging current so the incoming voltage stays above 4.75V. Using 24 gauge USB cables, especially with longer lengths, can increase the charging current. Most vendors don't tell you the wire gauge used in their cables, but Monoprice does (no relation, etc.).
When ever I drive, I have my phone hooked up to my Escort Red Line radar detector and my car's stereo via bluetooth (both). In order for me to use the radar detector effective, I need to have GPS and Blueooth enabled. This is a HUGE SUPER OMG battery drainer for my amaze. 20 minutes drive kills about 35% of the phone's power. My radar detector offers a slot to charge my phone BUT it still drains, not enough juice flowing in. Someone said it is because it's probably a .5amp.
So I am running a extension from the 12v lighter that's in the trunk to the front of my car. Amazon has a generic 2.1amp for 3 bucks.
http://www.amazon.com/Premium-Heavy...121&sr=8-1&keywords=htc+amaze+car+charger+amp
But on ebay, I found the original HTC car charger for 15 bucks which is a 1amp.
http://www.ebay.com/itm/HTC-Amaze-4...918506?pt=PDA_Accessories&hash=item27c867022a
What do you guys recommend? My logic says go for the 2.1amp, the phone will draw as much as it needs from it.
The 1amp.
Anything higher you'll damage the phone or the battery.
A wall plug power supply or a usb supply is 5.0v/1amp.
The 2.1 amp is probably 1 amp per port. Although it does not seem to specify.

That means a higher capacity battery (more current NOT MORE VOLTAGE) will damage the phone?!!!!
Totally wrong!
A higher current will not damage the phone. A higher voltage will do it!
Please do not mix the current with voltage!
Voltage is same 5 Volts (±5%) for these “USB like” applications (1A or 2.1A power supply our case )They use USB socket/connector but usually only pin 1 and 4 (+ and-)
Regular computer USB port can supply max 0.5-0.9 A depending on version.
For battery charging devices the current can go to 5A.
Higher voltage will trip a warning window telling you to disconnect and use official HTC equipment.
The phone monitors input voltage to protect the equipment.

and to add to that... unless you take the charger apart and short pins 2 and 3, it will only ever draw 500mA, as it assumes that it is hooked up to a regular powered USB port... I have bought multiple car charger usb adapters, and I have taken all of them apart and soldered the 2nd and 3rd pins together... otherwise charge time = forever, and sometimes it won't even charge if you have wifi or data/gps/bluetooth all going at once...
I recently got an Amaze and am generally happy with it. The biggest problem I have right now is finding the right car charger for it because the car charger I previously used (a 1A monoprice car charger) doesn't give it enough charge. I have been reading through the forums and some has been saying that if the charger is not working properly, it will recognize it as charging via USB rather than AC. In my case, the phone seems to be reading it as charging through AC, but there still doesn't seem to be enough current going through it. The phone will only charge if NOTHING is going on (i.e. screen's off, no GPS, etc.). I've been using CoPilot GPS and it draws the battery like crazy. Anyone has any idea as to which car charger would work properly with the Amaze such that I'll be able to charge (or at least maintain the charge) while using it as a GPS? Do I need to go up to a 2.1A charger?
I would look for a 4-5 star rated 2.1a car charger on Amazon.
Just read through the comments and feedback and you'll find one that's right for you.
I prefer the USB charger base itself and then using the OEM cable that came with the Amaze.
It seems to charge faster with that cable, at least to me anyway.
Remember though if it's rated 2.1a but has two USB slots that 2.1a will be cut in half if used to charge two different devices.
Hope this helps.
I couldve sworn we talked about this months ago. Let me see if I can find the thread.

you won't get the full 2.1a unless you usee a charge only cable or modify the charger as I stated above...
I ended up getting a 2.1A car charger and a USB charge only cable, and it's working perfectly. When I have the screen on full brightness and doing navigation with Co-Pilot GPS, my phone's no longer losing charge and is actually charging. The combo also works with my tablet as well.

This is damn helpful! So THAT is why when driving and using gps or whatnot I would always lose more battery even on charger.. So basically I can just solder the middle 2 pins together to trick it into thinking it is being powered like a home charger? No chance it will hurt anything I assume?

Hi all,
When I use the charger that came with the HTC One my phone charges great, rapid.
But when I use any other charger that I have in my home/office it charges very slow. Even with a 2.1 amp charger!
The charger that comes with the phone has an output of 1 amp.
I've tried multiple other chargers (1 amp and 2.1 amp) and they all trickle charge.
Anyone else noticing this?
Thanks
Joe
I'm using old charges at home and in the office and it did seems slow but had not heard of rapid charge. Will the phone indicate this rapid charge mode? If not, is it real?
I'm getting slow charging even on the stock HTC charger. Not sure how I can enable this rapid charge cause 4+ hours from 0-1% to full is a bit ridiculous.
use orginal charger is best , maybe it has some relationship with your battery life
If anyone is coming from phones with smaller batteries, remember the larger the capacity the long it takes to charge.
I use the cable and charger from my Nexus 7 and it charges fast. Off my USB it is slow.
Real AC chargers have two pins shorted. You can hack a USB to micro USB cable and short the same two pins to enable AC charging with any adapter, wall, USB, or car. Should be pins 3+4, but don't hold me to that.

i've done exactly this, and damned if the One still refuses to draw more than ~500 ma off of anything but the 2.1 A wallwart it came with (i don't have any others to try with). i'm about to dig out an old inverter to see if that will actually work. wish i'd paid more attention to my EE dad when i lived at home; i've gotten a serious crash course in this stuff while trying to get my One to charge in my car, when it's on.
edit: so i got my old inverter out, and spent about 15 minutes testing. i used the 2.0A adapter that came with my Nexus 7 to test, as well as the 3.1A Mediabridge adapter i got here. my phone was at about 45% when i started testing. unplugged, Battery Monitor Widget reported a drain of anywhere between 500ma and 650ma (running Ingress, wifi on). plugged in to the Mediabridge adapter showed, at best, a drain of 50ma. the Nexus adapter plugged in to my inverter charged at a fairly consistent ~120ma. i didn't touch my phone the entire time.
i left my Nexus 7 at work so i can't use it to repeat the test, but i will do so tomorrow. the cable i'm using is this one. i'm not crazy about having a ridiculous DC-AC inverter in my car for my phone, but if that's what i have to do so it can be used and not drain, then so be it. admittedly, i don't really understand these things enough to explain these variations, but i plan on learning ASAP. perhaps somebody else can shed some light on why the device charges different, and how it identifies an AC-USB adapter vs a DC-USB adapter.

Math doesn't support what is happening though. Phone has a 2300mAh battery. The OEM charger outputs 1A (1000mAh)
At most, it should be around 3 hours for full charge, when in fact it is closer to 4-4.5 hours. It's the last 10% that is the issue, it will trickle charge to 100% rather than rapid charge.

Yes, I think that's exactly what the HTC does... I read a pretty good article recently about Li-Ion batteries that talks about how trickle charging is the best for battery life, and it wouldn't surprise me if HTC got a little aggressive the way the this phone charges since we can't swap the battery ourselves.
I'm trying one last car charger, which matches the wattage of my Nexus 7's 5Vdc/2A AC adapter (which I've had the best luck with, when charging the phone while in use): http://www.amazon.com/gp/product/B009TBF7IG/ref=oh_details_o00_s00_i00?ie=UTF8&psc=1
If that doesn't work, I'm going to put a 300W inverter in my car with the AC adapters themselves and stop buying stinking DC adapters. This phone clearly pays very close attention to the wattage available from whatever it's plugged in to.

so got tired of not finding a fast charge mod so I mod the cable.
took a realy thin cheap USB cable and cut it in two. on the phone side chortsircut the data cables (white and grean) then connected the vcc+ and ground- normal.
the only reason I cut it in two was to be able to tread a shrink tube on the cable.
now I get fast charge from car and power pack and. and it works perfect.
now stop saying u need a special or expensive cable.
u need a knife and shrink tube and a heat gun (a cigaret lighter works)
and no u can't use this cable for datacynk only charge

Cool, thanks man, I'm gonna do that.
Why blow data when you can just get a cheap 4$ cable from newegg with 22 awg power leads. I linked it in confirmed usb cable thread. You destroyed a cable and made it special, hence using a special one instead of standard. The base is pre shorted. You increased AWG technically. Get it? You made a charge only cable, when these are special and can be had cheap anywhere. Buy a nice 4$ standard one with the right power lead awg and you can use it for anything.
...or.. Crazy idea here. Get an Android charger?
Cutting up USB cables is a bad idea, especially shorting them out. The data pins are not supposed to be shorted, generally 200Ohms is expected.
They are suppose to be shorted with fast charge... the base normally does this on plug in on AC switch. A USB3 port also does this... all he did was make a charge only cable. With fast charge 2 though, you won't make it much past 1A this way, just like USB3. Why our stock cable has thick power lead AWG and the phone can reach 1.8A.

As I said, 200ohm, not shorted... Anyway.
unless the plugg that u connect the USB cable in i sent chortcircut it won't fast charge whatever cable u use. this is for making a charge cable to use with carcharger ore power packs. of u use a wallcharger it's 99% certain it is already chotend and u don't need this. but if u use the original cable (fastcharge) it won't fast charge in a power pack or car charger.
and I charge att same speed with this cable then original charger cable that came with the phone. measured 1.8a with this cable that's all my Powerpack can output. can probably go higher depending on how mutch the phone can use.
it's li-po so should be able to charge 0-100% in 20min but whill shorten battery life and don't think oer phones can handle it
I fast charge with 3 different cables. Again, it's the AWG. Facts don't lie. My power pack and car charger are pre shorted, so all good. If not pre shorted though, you are correct sir.
my wasn't that's why I made this. so no matter what cable used it won't fast charge. Som people also say u have to by a expensive cable with is bull####
if someone can provide a link with a preshortens cable... well then show it. unable to find any
It is legit. I did this with a car USB cable when I had my One X. It would only charge at USB rate (500ma) even though it was a 1A charger. Using navigation the battery would discharge faster than it charged. Tried various cables, and only got it to work by shorting the data pair. After that it charged AC at full 1A.

Several available on Amazon:

Not always. My car cigarette adapter is modded to short data pins. It fast charges all my other devices and even my tablets, but doesn't even charge my G2. It says its charging, no slow charging messages, but still depletes battery. Only way toncharge in my car is to use the second USB port that is unmodded, which slow charges. Annoying.
I still think there is a software bug limiting the charging speeds because you can get different speeds by plugging in the same cable mulitple times.

We aren't saying you are wrong, you are just doing something different. It's not about expensive, its about thickness for the combo usb cable. Just the awg. What your solution does is increase awg. They are called charge only cables (pre-post short). What people were searching for are COMBO cables. You are using/doing something different. Why titles are called "working USB" cables, not charge only. We already knew this. There is bugs. That was apparent in the voltage testing. Something in the kernel isn't playing right at all times. I have seen this on my car charger. With no change in conditions, I can sometimes charge 200mA's higher with a replug.

Not always. My car cigarette adapter is modded to short data pins. It fast charges all my other devices and even my tablets, but doesn't even charge my G2. It says its charging, no slow charging messages, but still depletes battery. Only way toncharge in my car is to use the second USB port that is unmodded, which slow charges. Annoying.
I still think there is a software bug limiting the charging speeds because you can get different speeds by plugging in the same cable mulitple times.

The included home charger for the G2 is rated at 1.8A -- use anything smaller, and you'll see the pop up warning on the phone that charging will be slow and that you should use the "official" charger.
My guess -- if you can find a car charger that actually will put out as much as the phone wants to draw (e.g., 1.8A), and THEN use your shorted data lines, you'll see fast charging of the G2 in your car.

The 3SIXT micro USB charger I have is rated to 1A not modded, just bog standard. When charging I checked the battery stats and it says AC charging. Now I don't know if it has the data pins pre-shorted, but it managed to boost my battery by 10% in under 20 minutes. The phone was idle, but that's not bad going for a 1A $10 charger.
seems like the moderators did a god job deleting som posts.
just want to say I'm a sorry for my bad manur/attitude/language.
keep the input comming
here is another thread about the topic on another device

so got tired of not finding a fast charge mod so I mod the cable.
took a realy thin cheap USB cable and cut it in two. on the phone side chortsircut the data cables (white and grean) then connected the vcc+ and ground- normal.
the only reason I cut it in two was to be able to tread a shrink tube on the cable.
now I get fast charge from car and power pack and. and it works perfect.
now stop saying u need a special or expensive cable.
u need a knife and shrink tube and a heat gun (a cigaret lighter works)
and no u can't use this cable for datacynk only charge

not true have tried 3 other chargers 1.2 1.0 and 0.8 all say fastcharge (ac) with my modes cable. as long as it's over 500ma and with a cable with data pins shortend the slow charge warning is removed an the phone thinks it's charging from ac
charging my phone now with a Powerpack with 1a output and it says fastcharge (ac)
if I use the original cable it goes to slowcharging 500ma iv meshurd befor I put on the shrinking tube for isolation
and a car charger can output in theory 5-20a depending on your fuse in the car
the charging current is controlled by kernels in so phone. my old sensation u culd mod with a fastcharge Kernel so it never limited to 500ma always use max.
Samsung even has the ability to do a full charge in 30min but disabled in Kernel.
lg - g2 uses lipo battery's and culd actually be charged in less then 20min but if we do that u have to replace the battery every 6month at the best.
and lipo are extremely sensitive to over charge and the cells have to be charged with precision balans not to explode or swell.
