Looks like there is another option out in the market for adding battery to the Note 2. I currently have the Anker 6400mAH extended Battery. However this does pose a good alternative since it adds less in theback and just a tad bit more in the bottom.

Has anybody purchased or tried out? I'm curious to hear what people think. I may get it as a test dummy and report back.
Don't have experience with such case batteries, but I have spoken to someone who has. This particular type you mentioned above is very common on Amazon/ebay in 3200/3600/4000 flavors. It makes phone longer because of the bulk at the bottom and you can't access S-pen anymore - a big negative. There is an alternative someone got from ebay - 3200 mAh version: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=350655154588&ssPageName=ADME:X:RTQ:US:1123
It doesn't make the case longer and keeps the bottom open to access s-pen. The down side of this particular case and other battery flip cases is an average of 500mA Input which makes them charge up very slowly, and the same 500mA-700mA Output which charges the phone slowly as well. Also keep in mind output mAh is rated for 5V output while our battery is 3.7V which means down conversion eats into efficiency of the output thus output capacity will be lower.
Hmmmm didn't consider s pen access. Good point. That other option is interesting. I wonder how it affects NFC.

Hi,
So I've built myself a solar powered battery pack for my awesome Tab. Running into a problem though:
I'm using a 3.7V 10.000 mAh lipo battery and a switching regulator to boost the voltage to 5.3V through USB. The regulator is rated at 3A and my batterypack can do a sustained 5A discharge.
I've also built into the female USB the little resistors to "let the Tab know" it's connected to something capable of delivering more than 500Ma USB is specced to deliver (this thread). Problem is even with the resistors i'm only getting about 500mA of charge, much lower than when connected to mains... I'm thinking i'm still not convincing the phone it can pull more current, either that or something is wrong with my booster setup.

Hi WarlockM,
It was this one: http://www.lightobject.com/DC-to-DC-power-module-step-up-Input-35V28V-Output-535V-Ideal-for-solar-panel-regulator-P498.aspx
I measured the current coming out of the battery whilst charging: 500-600mA... Figured something wasn't right so replaced the whole setup with an all-in-one solution from ebay: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=220712755881&ssPageName=STRK:MEWAX:IT
This one really does a nice job, it charges the phone at 1.5A coming out of the battery so probably a little less going into the phone because of stepup (does require the resistors in USB though). It also smartcharges the lipo batterypack at 800mA straight from USB, or in my case solar panel aswell. What's more it indicates the charge level, so am pretty chuffed.
Will be posting pictures of finished product.
Cheers, Fred
I'm wondering whether any 3rd party manufacturer will sell battery case attachment like these for Xperia Z. I think should be easy for them to build a custom one for XPZ since there are contact points for charging on the side.
The following is for Samsung Galaxy:

You want this phone to be bigger?!?
3rd? Where is 2nd?
The 2nd party is either you or Sony, depending on your point of view.
yes would like to have these untill they are ultra slim and no fancy bright leds and they use the dockinng ports to charge is always good and people would buy it even if its slightly expensive as long as they use good materials to compliment the phone looks and feel * which I highly doubt
You mean something like this one? Cost me less than 20 Euro delivered here in Oz, pretty high quality and 2,800mAh. Fits the phone perfectly and uses the external power pins. Perfect!

Here's a test of the power pack. I would say that 2,800mAh is optimistic but it can sure charge the phone once. Good to see that output being close to 1A, too.

I bought this portable charger
http://www.amazon.com/Portable-External-Battery-Pack-Phones/dp/B00DW09QWS
based on battery info 2300 mAh
it works but only charges to 65% when my battery was 10% or 20% then appears this message :

when my battery is 75% or 80% it charges to 100% but drop energy very quickly from 100% to 90%
should I continue using it or not?
and what portable charger works fine with HTC One? thanks
no answer?
I used to use a Pebble smart stick http://www.amazon.co.uk/gp/aw/d/B0069Q6CGU/ref=mp_s_a_1_12?qid=1384980624&sr=8-12&pi=
I get about a full battery and a half on my HTC One. . I'd search about though as I'm sure they were £5 6 months ago.

thanks for your answer
weird thing that portable charger is 2200mAh mine is 2600mAh and doesn't work
now I'm not sure if I should order this http://www.ebay.com/itm/5600mAh-Ext..._Phone_PDA_Batteries&var=&hash=item43bb9d0f94
Maybe something to do with how many amps and volts.? I bought a standard charger from Leeds market a couple of years back which I intended to use with a HTC Desire HD, It used to start the Google maps app every time I plugged the charger in.. I assumed it was because it was 1 1/2 amps rather than 1.
Hi everyone, I have a Raspberry Pi Model B+, I'm very new to Raspberry Pi and learning as i go along,
I have a broken Tablet lying around, most parts in it will probably be too advanced for me to deal with right now,(like a 8.9 inch 1080p samsung panel) or possibly not even worth it
anyways, one thing that is interesting is the battery pack that's in it
it is not very old, and got 2 of them in it,

I read around and know that generally I would need a regulator to prevent overly powering the pi, but havn't seen a tutorial with something like this
Does anyone know what this is? i put the code on google and i find nothing.
or any suggestions would be greatly appreciated
thanks
Like other batteries
If you open any battery of an old phone, you can see those chips, so I suppose they are to control the amperage and the voltage provided by the battery, and also to control the charge.
Take a look to all that numbers and take note of the followed by V and mA. To fit well with the raspberry i suppose, V must be around 5, which is the voltage recommended for the pi chargers. For a bigger mA, the battery will give you more time of use.
These are all suppositions. I'd try to connect it. I don't think you can transform your pi on a brick by doing that...
This isn't worth doing. As commendable as it is to re-use old parts, a $10 cellphone booster from ebay can power a pi for a few hours per charge and is basically plug-and-play, with charging and regulator circuitry built-in.
Agreed with @Chris J.
Lithium Ion's are dangerous unless you know what you are doing.
You need to have a proper charger for it (ni-cd or ni-mh chargers will not do; they have a consistent voltage output until they are just about dead, compared to li-ions, which have a mostly linear discharge cycle from 4.2V until they reach around 3.6V).
Anyone who bought a new (3rd party) battery and made good experiences? After 3 years of use my battery has lost around 30% capacity so it's not complete garbage yet and any replacement would need to be new and high quality to be worth the hassle.
AliExpress would be the easiest but is usually also the least reliable.

I'm more interested where to get either of those two batteries in europe and for how much !
All of them look like pouch cells. The biggest problem i see is that if both pouches have the same maximum voltage (not nominal), since overcharging lithium cells can be combustible.
