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.

Has anyone found a portable Battery pack that we can use on the TF? I have several that I have used for my iPhone and my old iPad2 but all are only 5v. is there one out there that can charge out TF or is the keyboard dock the only way to go for extra Battery?
There are several battery packs used for notebook computers that will work listed on Amazon. Just be sure they have a 12Volt output. EverReady had as battery pack that will also work but you will need an adapter provided by them. The key is that you need an output of 12 to 15 volts to charge the TF or Keyboard. You might read Devcake's post on a DIY charger for the TF as information on the voltages required to charge the TF. There is also a post on external batteries that might help.

You will need a conector for Asus (Willy cable WI15) from them. You will have two free tips a year for the life of product
By any chance do you know the tip number?
The cable you note doesn't appear to connect directly to the Transformer.
What setup are you using to connect to the Transformer?
Thanks

I just saw this while I'm looking for a battery pack.
On a german page I found this interesting:
w w w.intecro.de/XTPower-MP-16000-Powerbank-mobiler-Akku-mit-16000mAh-fuer-Laptop-Handy-iPhone-iPod-iPad-PDA-MP3-Player-mit-20-Adaptern
(can'f find an english page for this product)
Could I use this one by using an adapter?
I just got an Anker Astro3 10000mAh battery pack. I plan to use it while camping this summer, mainly to charge a phone, but occasionally to charge my tablet.
It is intended to charge 5V USB devices, and has two USB ports. It also has a 12 volt port. The adapters for the 12 volt port, of course, do not work with USB or the Transformer. So I made an adapter, and I am good to go now for charging the tablet.
The battery pack charges from a 12 volt wall charger. I have also made an adapter to charge it from the 12 volts on my motorcycle. So I will be charging it from the motorcycle during the day when riding, then using it to charge my devices in the evening at the camp. I've already tried it a couple of times, and it worked well.
I tried to charge the battery pack using a solar panel, but the solar panel was far too wimpy. It was like trying to run a house air conditioner from a penlight battery. It may make you feel good to try it, but it isn't going to do much.
So far so good. This is very close to what I need.
The issues I have had to work around are:
1) I want to also charge an in helmet bluetooth intercom from the USB port. But the charge current is so low, the battery pack auto powers off, thinking nothing is plugged in. Not a big deal because I can plug in my phone at the same time. That keeps it turned on until everything is charged, then it auto shuts down.
2) When I charge the Asus Tablet, it doesn't appear to auto shut down. Just the opposite of #1, it looks like the load stays high enough to never shut down when charging the tablet. This may not really be true, as I have only tried it a couple of times. Also, it isn't good for much more then one and a half charges of the tablet, as expected.
3) You need to figure out your own harness to get the 12 volts to the tablet.
4) No charge cable for a car. I mean this is rated for an input of like 10 to 15 volts, or some such. This thing is GREAT for charging portable devices. Charging it from a car is as simple as a cable, but there isn't one.
Over all this charger is a winner. At right around $55 US, I recommend it, if you can fabricate a plug for charging the Transformer.
Try a 12V UPS type battery along with a 2A fuse and adapters. It only costs about $20 or so. Plan on using only 50% of its capacity and recharge often to get the most life out of it.

For me, this is actually what I use now. But it has issues.
One is simply that it is large. I carry it in the trailer that I tow behind the motorcycle, so it is OK, but a bit too large and heavy. It is a gel cell that has about a 48 WattHr capacity. LiIon has a a lot less and weight. In this case, it has about the same capacity, in a very small light weight package.
The other problem is charging the lead acid battery is an issue. I need to carry a AC charger and find AC when camping. I put a diode/resistor combo in the trailer and tapped off of the taillights. but by the time the weak motorcycle voltage gets to the taillights, add in the diode and other losses, and I'm lucky to see 13 volts at the battery. Not enough to charge it very well. The LiIon pack I use has the supply built in to charge properly from +12.
So I've tossed the lead brick battery (literally) and upgraded to a portable LiIon pack. So far so good.
This is what I use "Portable 12V DC USB 5V Rechargeable Lithium Li-ion Battery Pack for CCTV Camera" search on ebay, you can get one up to 13AH
I got a 3.8AH version for $16 , Dimension: 9.2cm X 6.0cm X 3.0cm
Outout rated 5V (5.8AH) and 12.8V (3.8AH)
small modification because the charger is NON-US wall plug, I just pull the plug pin out and add in a regular power cord cut off from an old appliance
Keep the USB plug for 5V use, cut the 12V DC cable and connect it to a female USB cable (pin 1 and pin 4) , then you can plug in the Asus usb/charge cable directly and charge or power the Asus

Alot has been said about the quality of various batteries that we are all looking at for our devices...however very little about the different chargers that are out there.
I thought my charger that I bought was defective cause I let it charge overnight and it wasn't fully charged. That is not the case.
The Charger that the Note comes with charges at 1A. Most of these external battery only chargers charge at 350mA.
Take a look at this calculator:
http://www.csgnetwork.com/batterychgcalc.html
Using the link to the calculator above, you should expect a 2600mAh battery to fully charge using one of these cheap chargers in about 9 HOURS!! The charger that the note comes with should expect about 3.4 hours. That's a huge difference in charge time!!
So be sure to take a look at the output of these chargers before you get too excited and purchase one. If it takes you 24 hours to charge a battery, what good is it to you?
Thanks for the battery reference URL.
This is basically another scenario of 'you get what you pay for..'
It seems to often apply to batteries and chargers.
Whereas for like cases, you have a better chance of actually saving money and getting quality at the same time.

So I guess for battery longevity, you should use a 500 mA charger (the typical USB output). That way it doesn't charge it too quick (and overheat the battery).

No, actually. Lithium ion batteries, unlike nickle-cadium batteries actually perform and last better with short, fast charges. Android's battery stats are helped by a few full cycles, but it is not better for the battery to full cycle or slow charge.

*I am not an electrical expert, I just play one on TV.*
There are standards for USB outs. Just Google the standard. That said, there is USB1, USB2, and now USB3. Check your motherboard to see which one you have. There is also a newish thing on motherboards that will do a rapid charge by changing a setting on the BIOS. That's what i got off the top of my head. Do a little research.
As was pointed out on another thread, the Note looks for a low resistance/short between pins 2 and 3 of the USB cable. If it sees the low resistance, it enables a high current charge; otherwise, it sticks with USB standard charge of less than 500 ma. The 2/3 pin setup is not true of USB connections to a computer. The Note power adapter is set up this way to do a fast charge. Most chargers and portable battery chargers leave pins 2 and 3 unconnected, so they will not fast charge a Note even if they can supply 1A.
I purchased a Scosche 5000 mah battery with USB ports for charging Ipads, Iphones, and other devices. It also charges a Galaxy Tab with a special USB adapter plug. I tried the Tab adapter with my new Note and it was charging at 5 percent charged every ten minutes or so. Without the USB adapter, the Note charged at 2 percent every ten minutes or so. Without the adapter, the Note displays an MTP initialization notification. With the adapter, there is no MTP notification.
The Scosche battery is a big improvement over older Trent 5000 mah batteries. There is a push button to turn the Scosche battery on. The battery will turn off if no device is attached or it the device is fully charged. One of the ports can output 2.1A for an Ipad. The Trent battery would run down if it was left on.
Staples carries the Scosche battery for $80. I used a $29 online coupon from Staples that expires 3/5/2012.
I did not see anywhere on the Scosche website where they sell the Tab adapter by itself.

Do you have a model number on that USB adapter? Maybe in the instructions?
There is only the name Scosche on the adapter. The guide only calls it the Galaxy Tab adapter.

What does an "MTP initialization notification" look like on the Note? How do I identify it?
If I don't see it when charging, does that mean it's getting a fast charge for sure, or just that it might be?

How exactly would you use a multimeter to do this? From what I've seen, they have two contacts -- where would you stick those? Or is there some kind of micro USB conversion thingy to use with a multimeter?

Cut a USB cable, and strip a portion of the power wires. Set the multimeter to a 10A DC current scale (assuming it supports 10A, but most craftsman and up do, with common and a 10A lead), disconnect the plug, attach common to negative wire and positive to positive wire, gator clips or something, then plug it in and read it. The current support and time it can be on depends on the multimeter. Mine does up to 10A for Max 30 sec.

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?

Hey guys,,,,
Wanna ask something here...
I have an idea to buy a power bank/portable charger, instead of buy a spare battery.
But there are alot of choice, start from 2000mah-10000mah capacities, offerring 2-6 USB port.
Each product offered different USB port voltage and ampere.
For the example, each USB port supplying 5.3V / 5.0V and 1A / 2A / 0.8A....
Do you know which one match/compatible with our phone?
From what i remember from my physics class the should all be compatible. Cellphone battery is 4.3V, so it needs a power higher than that to be re-charged, a pc usb port usuall supplies power at 5V, whilst the A is the amount of energy let through, so the difference in A value impacts the speed at which the portable device recharges the phone battery. The same voltage carrying 1Ah reachrges the batter in half the time needed by one carrying it a 0.5A. Furthermore cell batteries have an internal chip which regulates the tension transmitted. The mAh is the total capacity of the recharging device (or toal amount of A it can store and supply over one h unit of time)
I think the the amperage of charger shouldn't be more 1.0 A. More amperage will charge the battery quickly, but will short his life.
so, I should go for 5V and something under 1.0A?
a product that nearly match those config was sanyo eneloop.

so, I should go for 5V and something under 1.0A?
a product that nearly match those config was sanyo eneloop.

At spec of Sanyo Eneloop i see when you use only one of USB port and charge one device you will have charging output of 5V and 1A. When you use both ports you will have charging output of 5V and 0.5A (500mA).

I see....
Thanks for the explanation...
Maybe I should go for Sanyo, cause the other products was made by some unknown/unfamiliar brand from chinese.
Better to choose a wellknown brand right?
That's because as i explained before Amperes is the amount of energy that passes through a conductor, if a device has max output of 1A if you use two ports it will obviously split down the tension output. Amperes have nothing to do with battery life, it's not gonna do anything if you charge them faster, what matters is tension (V) which is maintained constant by the chip within the battery itself which gives the battery the 4.25V constant it needs controlled also by the cellphones internal regulatory hw. Poli-ion batteries use an impulse charge system, it's not continuative, that's why constant regular tension is important, aamof recharging the cellphone from car charger does affect negatively battery life. Poli-ion batteries if left unused have a very slow discharge rate, 1% a month, nonetheless life is shortened by about 25% after 100 full cycles and another 25% after 3-4 years of life, and they have no memory effect, so it is always best not to let the battery discharge completely ...Go for better known brand, not for the quality of the product per say but for more guarantees on support and warranty claims

I'am sorry if I can't understand your explanation fully...
So you mean higher Ampere output than original charger was safe, Am I right?
I bought already sanyo power bank, seems like a nice quality.
Charging time almost same like it was charged on PC USB port.
Thank for your complete explanation
tho I cant understand that completely (stupid me)

That is the best way. I was trying one solar charger, with included LiPo battery with 2600 mAh. The charger was with dimensions of an iphone and can charge included battery from sun and from regular USB charger. His price was something around 6-7 pounds. This kind - Portable-iphone-2600MAh-USB-Solar-Panel-Battery-Charger-for-Mobile-Phone-MP3-MP4 (search in ebay, because i'm a new user and can post links ). Included battery can keep charge for 1 full and one 70% charge of mi Xperia Mini Pro with standart 1160mAh battery. Hope this can help you. The advantages of sanyo charger is that, you can use regular AA battery that you can buy it from every where.
P.S. Sorry for my english. Hope you can understand me
your english was understandable bro
ahhh...a solar charger...will keep this in my mind.
traveling too much with smartphone will be easy with a solar charger
So I have started using an application on my Note 3 that is pretty much a battery muncher, GPS, Data, Processing, Graphics the works. I am looking into some options for extending battery life with some accessories. I was originally planning on getting 2 batteries with a charger but I'd like to also consider a portable battery pack so I can share the power with friends. What I am curious about is whether or not the charger can support the 900ma/h charging rate. I was wondering if the standard usb port can support the power as long as its a micro usb 3.0 connector. To simplify I just need to know that if I have type A usb connector to a micro usb 3.0 connector can I charge my phone at the fastest rate. And does the output of the charger have to be at least 1A?

I own two battery packs. Both are from a company called PowerGen and I picked them up on Amazon.com. One pack is 12,000mah the other is 5,200mah. You just plug your regular charging cable into one of the standard USB jacks in the battery pack and turn it on. The larger pack has a 2A jack and will charge at a fast rate. When I was using the Note 2, I used a special heavy duty charging cable that I picked up on Amazon.com and that cable allowed the Note 2 to charge at a faster rate. I have not tried to use the cable on the Note 3, but I might soon. I feel that battery packs are a much more flexible approach than extra batteries. You can get more than one recharge on the battery pack. I addition, I use the battery packs with a large number of other devices. If you get a new device, the battery pack can still be used.

YUp. I have an old anker external battery with 1a and 2a ports, the 2a port charges my note 3 at 1800. To be fair it is picky over the cable used (a decent quality non ribbon cable) and the temperature of the phone and battery (thermal throttling which is perfectly sensible to avoid cooking the battery and phone). It appears that there is a lot of variables that can potentially screw up a decent charge rate for some folks some of the time. My experience with the anker battery pack has been excellent, even nearly 2 years later after daily use.
Personally I am getting a little tired of the whole charging the battery twice a day so I am looking at a larger battery. The zerolemon allegedly affects signal quality, the 6400mah ones from elsewhere seem to come with shocking cases so I am still looking. It would be great if samsung came out with an extended battery and case. You think they would be after that money.

How do you check what the charging rate is And id like a cable that bends with no resistance unlike the factory cable .
Theres a free app "galaxy charging current lite", seems to be pretty accurate compared to time taken to charge.
As for the cables. I checked quite a few cables and I noticed that the higher quality cables, more expensive, thicker, better connectors etc were far more likely to charge at a higher rate. I would not be shocked if some of the cheaper cables, especially the flat noodle types were skimping either in the cables or the shielding. I could be entirely wrong of course but I did attempt to limit any other variables like being in airplane mode, low room temp, battery not near fully charged.
Don't get me wrong, I find it a huge PITA using a stiffer cable but that is why I am looking for an extended battery that doesn't leave me with the worlds worst case or stuff up the signal.
Can anyone recommend a good car charger and a battery pack around 10,000 mah

I just posted the car charger I am using with the charging cable that provides a 1800 mA charging rate on the note 3 http://forum.xda-developers.com/showthread.php?p=48626737
I just won a bid for a 12000 mah floureon portable charger 12.99 on ebay free shipping should be here today

I bought a floureon 12000 portable battery I was wondering what the 1 and 2 usb are for thanks for clarifying is it bad if I use the 2.a every time I charge fast will that effect my phone heating up etc?
Sent from my SM-N900T using Tapatalk
2 a is not bad. That is what the oem charger is. Depending on how much juice the app is using 1a won't cut it.

... for devices that only need 1A or less....
I use myCharge Amp 6000xt when I'm travelling. Plugs right into any US outlet to rechage, and can charge at up to 2.1A, with 3 USB ports available (1200mA typical charge rate on my Note 3 using a generic USB cable, according to my charge current app).

Most phones only come with a 1A charger, while most tablets (and Note 3) come with a 2-2.1A charger. I have an Power Bank battery with a 1A port and a 2.1A port. The 2. 1A port is the only one I use to charge my Note 3, and I use the 1A port for other phones and/or my blue tooth headset.
