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.
i'm reading different opinions about this when i searched through the xda forums and on google.
i'm using the same custom rom and kernel for about a week now. a few days ago, i charged purely on wall socket. left overnight, my battery lost only 2%.
last night, i charged my phone when it was about 30%. i charged using usb up to 85%, then i finished it off on AC up to a 100%. my overnight loss went up to 5% (i did not install any additional apk, or change my setcpu profiles, etc).
there are no topics on this, specifically for SGS2. mostly are from HTC threads.
from what i learned, usb's only pour out about half of what AC's can give (500 mah vs 1,000 mah). does that translate into a poorer batt life?
How you charge your phone, usb vs AC will not effect the battery life, 100% is 100%, it will just charge slower via usb.

I have noticed something similar with my captivate.I would guess that when you use the wall charger with 1amp the battery gets more of a charge than when you use a usb charger at .5amps. 1amp can cause more chemical change in the battery than half an amp.
sent from my Infuse at Tranquility Base.
SGS2 will only let 650mA into the battery, AFAIK it's hardware restricted to do this. Wall charger will charge faster, but only slightly.
I see no difference and 2% to 5% is within a tolerable variation of overnight drain .
Its all the same electricity .

Firmware, actually, and the phone determines how much it will draw based on the resistance between the two USB data pins. If the resistance is < 200 ohms, it assumes it's plugged into an AC charger, and will draw up to 650 mA. Otherwise, it assumes it's plugged into a PC's USB 2.0 port, and will draw up to 450 mA, just under the 500 mA that a USB 2.0 port is supposed to provide, per the USB 2.0 spec.
Since it's firmware, it should be possible to change the current draw by re-compiling the kernel sources with new values. Note that you don't want to go too high on the charging current, as that could cause overheating or fire.

And how about charging a spare battery using a separate battery charger?
I have two batteries and I never charge them plugging the phone, just using a spare battery charger. Does it have any negative effect on the batteries' lifespan?
dont know what happened but my phone is being charged with ac adapter as same speed as usb.(more than 4 hours) :S
I have a USB charger capable of delivering 1A.
Even with the data pins shorted (phone side), it still seems to draw only 350 mA :-(
Any ideas?
Known made-up cables that do work?
Just curious if there is an app or something similar that would show how many amps are being provided when charging through a wall charger/USB powered hub? The reason I ask is that I'm thinking of buying a powered USB 3.0 Hub. The adapter that came with our phone says it's 2 Amp, so I am assuming our phone can pull 2 amps for charging. Just wanted to verify in some way that a 2 Amp dedicated port would really work for this phone.

When I get home, I'll download the kernel source and see if I can find out how much power it draws during charging. I doubt however, that it will draw 2A during charging as most chargers are rated to supply more power than the phone will accept.
Yeah, 2A seems like that could melt a battery charging that fast. Someone sent me a private message and told me to try CurrentWidget. I threw that on the phone and it registers as 1A while charging. But it appears like the widget doesn't break it down with decimals. For instance it could be charging with 1.8A and wouldn't know it. I put it in a standard USB port and it reported as charging with 0 Amps but the battery was indeed charging.
I took a quick look at the N7100 (International Note 2) source posted on Github by CM and it looks like AC charger is 650mA, USB is 450mA. It's a little hard to tell what exactly it's using for charging, so I'll try to verify that when I get home and have a chance to take a better look.

A 3100mAh Lithium Ion battery can easily handle a full 2A charge rate. The ideal charge profile for Lithium Ion is a CC/CV profile, starts at constant current between like 3V and 4V, which most LI batters can take a rate of 1C, meaning it can handle a charge rate of 3.1A, recommended charge rate to achieve the most possible charge/discharge cycles is usually 0.2C so for a 3100mAh battery that would be 620mA. Once the charge gets to the correct voltage it gets to constant voltage and charges until termination current usually in the 100mA range. So yes, it can handle a 2A charge no problem.
Hey there. I very much appreciate that breakdown. Makes me wonder why they dropped the amps so much during charge.

If this is true (first time I've seen this anywhere), that would line up great with the 650mA max charge rate I found. Also, I downloaded the VZW source, and it doesn't look to significantly different from the N7100 source, at least as far as the charger stuff is concerned, so I would say they both probably have a max charge rate of 650mA.
I appreciate the info and time you both put into this. I guess it means a 2A usb port will be slight overkill. Even changing the charge rate to a higher value seems to indicate a lower battery life. Makes you wonder how apple did it's math for the ipads charge rate. The battery must be huge to accommodate a 1.1A charge rate. Or they are sacrificing battery life for fast charging.
Wont the kernel dictate the charge rate no matter what the charger is rated at?
If the kernel is set for a charge rate of 650mA (0.650A), then why does the Note 2 have a more powerful 2A wall charger, while the GS3 has a 1A wall charger.

The original nook color 7" came with a 2A wall charger and that was 2 years ago... both my note 2 and nook color charge about the same rate (quick to 99% and slow to 100). The charger is probably cheaper to make at 2A rather than anything and plus it could be used to charge future devices. Also if you used a 1A charger to charge the note it might possibly get warm/hot from running at near full capacity.
Im using my OLD blackberry 700mA wall charger to charge the phone at night while im sleeping. No problems with heat.
Hi people
Since I'm part of the lucky people owning a Huawei Ascend Mate 7 (MT7-TL10), I'm actually looking some accessories like a quick charger.
I wish a charger better than the original one if possible, with EU pins, and with a good quality checked (I prefer to avoid some product with awesome specs but not tested ...)
So anyone have any idea where I can find a good charger, and without any risk for my phone ?
Thanks

just to know more fasting to charge wil damge your batter of mate 7 quickly .also orignal 2 A will damge
for me I charging with Iphone charge 1A good for batter and Stander and low risk to Device
If you want proper charging, then always use the accessories coming with that product. It is tested for sure and good. Other than that, you can use any charger delivering the same charge. The original charger is 5 volt, 2 Ampere. Don't use anything above 2 amperes as it may damage the device. Below that will charge it slowly.
BTW, why you don't want to use the original charger?

Can you test it with ampere (free in gplay) i don't think it will charge over 1800mA so that it acts like a normal 2a charger
Fast charging
Using a fast charger will destroy your battery faster. Not recommended as the battery is not removable. You can get a battery and if you are comfortable removing the back and swapping it out then go for it.

that is not correct as you are not connecting the charger to the battery directly. In fact the charger is just a power supply. The actual charger is integrated into the phone (charging controller).
In general you need to know that volts are pushed to the device by the power supply and amps are drawn by the device (phone) from the power supply. Therefor using a power supply with more than 5V will kill your phone but using one with 2A, 3A or even 4A will make no difference as the charging controller will just pull the amps required. Because of that you can not really fast charge a phone by changing the power supply only if the phone supports the fast charge option (for example some Nexus phones).
I tested this myself with a power supply (can provide 5V and 1.5 to 4 amps) and an amp meter. The phone always drew between 1.5 and 1.6 amps (with and empty battery, 8 to 10% left) regardless of the selected amps of the power supply. Using a power supply with less than 1.5A will kill the power supply as the phone tries to draw the 1.5 amps or more. As result the power supply will get hot and eventually die.
Since battery is not removable be careful with fast charging, since it will decrease the life span of the battery and in the end it will just give you less battery performance.. it is stupid... however.. there is situations where it can be really needed though but not on a regular basis..
Last weekend I would really had needed fast charging.. It forced me to spend about 3 hours on a cafee so I could make it 100% so I did know I did survive the day with gps and all other things.. However in these situations I really like the ultra power saving mode..it saved me that night.. when I was lost in stockholm.. and my phone was really the only way to get contact with people

Why don't you buy a powerbank? I can advice you the xiaomi 16000mah. That one charges fast and you can be mobile.
Any recommendations?
I wonder if a S6 charger do the trick. Stock charger is too slow damn. Spending 3 hours to have a full charge is not acceptable for me.
I'm going to be honest, it doesn't really matter how you charge your phone as long as you don't go over 5v and 2 Amps. Batteries will automatically lose cells from charge cycles and by the time you feel the effects of the battery going bad, you would have already moved on to the next device for the next person to worry about. And saying to use the Stock Charger isn't really good enough as the Stock charger doesn't serve as a Car charger also. If you want to charge your phone quick, and you already have a 2 Amp charger, Check your microUSB cable. Don't use junk cables, buy quality or use the cable you received with the device. You get what you pay for. Fast Charging won't work as the Charger has a chip inside that communicates with the Phone and Device. Also, when buying a charger, don't just randomly buy a charger online, Make sure its UL Tested. Even if it says UL tested, there should be a test number on that UL Label, take it a step further and google it and make sure it matches the charger specs and passes as knockoff chargers are notorious for copying other chargers Regulatory icons to make it seem authentic. You don't want to buy a junk charger that ends up burning your house down or gives you a very bad 120 Volt shock through the microUSB cable that would also kill and fry your phone.

You have not read my earlier post or you did not understand it. Changing the charger on the Mate 7 will have NO effect (zero, nada) on the time required to charge your phone except the charger delivers less then appr. 1.6A. Then it would take longer and evetually kill the charger. The Mate 7 uses a Kirin chip which has no fastcharge implemented. Samsung uses Qualcomm Chips with implemented fastcharge technology. The charger (in fact a power supply) and the phone/CPU/charge controller need to communicate with each other, otherwise fastcharge will not be activated (the reason fastcharge with charge-only cables does not work because they lack the required data cables for communication).

Wrong. Correct would be "I'm going to be honest, it doesn't really matter how you charge your phone as long as you don't go over 5v." The amps of the charger don't matter at all -> amps are PULLED by the phone not pushed to the phone. You could use a charger with 100 or 1000 amps and it would not hurt your phone a bit as long as it is only charged with 5 Volts.
More amps (>1.6A) on the charger do not improve the time for charging one second.
1.6A is nothing. i use 2.0A and it still chrges 3 hours.

Yes, and that won't change one bit even if you use the best and most expensive charger and a 1000$ cable. The Mate 7 is limited by its hardware (built in charge controller) and pulls max 1.6A. End of story.
As long as you don't understand how charging works you will spend 100's of bucks for cables and chargers to no avail.
The only reason, why charging with some charges is quicker than with others is that those chargers actually deliver the amps they are supposed to deliver. There are a lot of cheap/bad chargers out there which are labelled with 5V/2A but only deliver a fraction of the amps. You can identify those chargers easily because they get extremly hot. I use a 2A charger from Aukey which gets only lukeworm.
I know there is a thread about what charger to buy, but I have a specs question. Mine z5 came with the International charger and I am in the US. I noted it is 5v and 1.5a. I have a 5v 1a charger on hand. Can I use that?
Sure, it will just take longer to charge.
No lasting negative effects on the battery?

Most certainly no negative effects. In theory it should actually be better for the battery to charge it with less current, but I don't know if that is true.
Different topic: I read that there are multiple versions of the Z5 (US, Europe, ...) and that they support different LTE frequencies. So maybe you want to check if your mobile connection works as intended, if you don't have the US version.
My phone is showing LTE after choosing my apn settings.
I tried using a 5V 1A charger with my phone and it doesnt seem to work. (It works fine on my old phone) The charge light keeps turning on and off. The vibration pulse you hear when it starts charging keeps pulsing too.
Better use an HIGHER amperage, than lower!! Charger will adapte it to phone specifics...A lower amperage will reduce your battery capacity in long time.
I once connected my Z5C to an old 500mA charger (caught the wrong cable) and kept using it a bit (screen on, etc.) and it gave me a nag screen that said that the charger is not suitable because apparently the battery drain from usage was more than what trickled back in.
However, if left alone even a 500mA charger should eventually charge the phone, taking much longer though.
Generally, with chargers, you need to get the voltage right. If the Amperage is higher that what the OEM charger is it does not matter. The electronics in the device limit the charge to what the device can handle. The Amperage on the charger is the max it can deliver. In other words, the charger does not pump 2.5A into the phone forcefully, the phone just nibbles whatever it can take (say 1,5A).

Any reliable source for that? The charging will be slower - yes, but I seriously doubt, that this has negative long-term effects on the capacity.

I think you need a 2A charger to be sure with the Z5c. Most of my older chargers take hours to charge it, and the car USB port (Nissan Qashqai 2015) barely charges it at all.
The UCH20 that came with the phone, takes 2 hours 15 mins to charge the phone fully. I got a quick charger which takes around 1 hour and 10 mins at max
Wow, really?
It is basic electronics. The voltage must be the exact one. Amperage is what the device draws , therefore the charger must be capable to provide a minimum not a maximum.
I repeat, it is basic electronics!
Now a more pertinent question :
What are the voltages for quick charge ? Does anyone know?
If someone has a original charger with quick charge can you please state what voltages are written on it?
Should be 2 or 3 voltages with lowest 5V
Edit : Found myself the info on Sony UK website of a Sony charger.
