    I'm broke, and my battery is shit. Phone "dies" at 50%. Tried a friends battery, works perfectly fine. So, I need a new battery. I know what it takes: 2100 mAh, 3.8 V Li-ion 7.98 Wh. I know what those values mean (from a layman's point of view), but I have a point in question.

    I see a battery on the 'ole eBay: 3200 mAh, 3.7 V, Li-ion. Says it is compatible with my phone. Simply put, higher capacity, similar voltage output. Would it **** up my phone with that .1 difference? If so, do you recommend the stock Samsung battery? Or an off-brand?

    Like I said, I'm broke. I don't mind waiting a month to have it ordered from China to save a few bucks, but I'm not buying another battery for $35 from a store, when my phone was purchased used for $30.

    **Update: I average about 1% a minute, and it died at 47%. Needs to be plugged in order for it to be rebooted.

    Thanks in advance,

    John, It is as near as makes no difference the same thing. Except it has a larger capacity. The new battery is at a lower stated voltage, so no it will not damage your phone. To be honest, I think that the 3.7 is a typo - it should be 3.8. It is a chemical reaction, which, when charged, should produce the same voltage every time.

    Check Amazon. I got a two pack of replacement OEM batteries under $10.

    I'd avoid any bargain specials or off-brand batteries, too many are manufactured with little quality control using cut-rate components. Saving a couple of bucks isn't worth the increased chance for one of those knock-offs burning up and frying your S3. As Jfalls63 suggested, it's less than $10 for a Samsung OEM battery. (Also note that while some phones have the NFC chip in the body of the phone, with S3's it's in the battery. Some off-brand S3 batteries don't even have the NFC chip in them.)

    I've decided on an OEM battery. In the sake of getting it sooner, it'll be about $9, but it works for me.

    Thanks all.
