So, 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.
