    I know that the new battery in the S4 will be 2600 mAh compared to S3's 2100 mAh,
    But can you use the S3 battery in the S4.

    It seems to be the same size, the phones are close to similar size as to the battery area.
    I have multiple batteries from the S3 which would be nice to continue using on the S4.
    I dont know if the upgrade from the S3 to S4 is worth it without losing the oppurtunity to use the extra batteries.
    I am a power user and switch batteries often and I really do not want to buy more batteries in the near future.

    It all depends on many things, where the connectors line up, is it thicker or thinner, taller or shorter you just never know until its available.

    Very doubtful. It's unlikely they were able to increase capacity by nearly 25% in the same physical package.

    There is a chance, albeit a small one. The 1500 battery from the s1 and the 1800 from the s2 were interchangeable between both hardware lines.

    I would not recommend doing this. The S4 battery has better battery life in oppose to the S3. I would never put in a 2100 mAh battery into a S4 which supports 2600 mAg.. Though you can still use the chargers! lol.

    Im sure the S4 will have better battery life. But this isn't a known fact since the device isn't really out yet.

    Yeah I doubt the batteries will be interchangeable.

    It's better, although playback just looks sad when you see the other jumps in performance. This is the Snapdragon version btw.

    No clue as far as swapping batteries, though.

    The S4 has a 2,600mAh battery because that's what it needs to properly power the larger screen and the crisp higher res display. Putting in a 2,100mAh battery is kind of illogical, unless you can charge it very frequently.

    I also have 3100, 2700 and 2500 batteries. The housing for the battery looks the same as the S3.
    Batteries are being developed to last longer. Why is it impossible that the same battery size can now hold 2600

    If they fit, the spare S3 batteries would still make decent backups for when the primary battery gives out on you during the day. Using a less powerful battery won't hurt anything.

    Chemistry. You can increase the output of a LI battery in one of two ways: Add more individual cells inside the case, or use larger cells. The only way to do either, without changing the outside dimensions of the battery, is to make the walls of each cell, and possibly the membrane within each cell, thinner. Google Boeing 787 to see what happens when you make the cell membranes and walls too thin.

    That ladies and gentlemen works just fine for me. I sold my GS3 thinking I would be happy with my next phone, but sadly after one month I am ditching the carrier and the phone. Switching to AT&T and will be pre-ordering the GS4 32GB in Black on 4/16. Looking forward to actually being able to read my device. I still have my iPad 4 128GB though on Verizon so I do have lots of mobile storage for bigger stuff.

    Well put, I would rather not have a battery like the Boeing 787 in my pocket that might not be good for parts of your body. On a side note I wish the OEM's were not in a race to the bottom with how thin they can make their phones. I would rather have a slightly thicker phone with a thicker battery and better battery life, like the GN2 has. But I like the battery performance we are seeing so far on the GS4.

    S3


    S4


    There's indentations on the top of the S4's battery, three prongs on the bottom, and it's not as tall. The S3's batteries won't work.

    Of course they always need to make the new battery be different to insure you buy a new spare. I will be getting a spare this time, just in case.

    Yes - this 100% works and I do it all the time. The battery capacity is definitely lower, but not by too much, and makes for a great backup. I wouldn't specifically go out and buy extra S3 batteries (may as well buy the proper S4 batteries) but its a great way to make use of any spare S3 batteries you have laying around. Heres the video:

    More importantly will the higher capacity S4 battery work in the S3 I'm stuck with for another year?

    Damn, damn, damn! I just gave away two high capacity S3 batteries after getting the S4 as I thought they wouldn't work/fit! Now I know different!!

    Just to clarify: mAh does only say something about how long the battery can supply the device. As the youtube-clip says: the only important thing is that the voltage is the same!

    I have a larger battery for my S3 which requires a special back. I bought it from eBay and it works very well.

    Or rather I had one. I lost it a couple of days ago, just when I really need it (at a conference; the battery doesn't last all day, I really need the phone, and there's nowhere to charge it).

    I notice the local electrical goods store has batteries for S4. I didn't see any S3 batteries. I was thinking of going back and buying an S4 battery if it is interchangeable.

    thank you very much ... another question please..... if iam connecting my s4 mobile to a flash usb drive using otg cable ... can i record from the camera directly to the flash drive .... or i have to record to the sd card 1st then copy recorded files to the flas drive ? thats very important to me because i want to use the phone to record big videos without stopping or pauses and the storage capacity in the phone is pretty limited .. but a 16 gb flash drive when connected via otg that will do it.... thank you very much
