I bought a 4000mah battery and want to know what you guys think of the results. First of all the battery. It cost $15.80 + free shipping on Amazon. Vendor 'ecell' advertised the following: Features: Made in Japan 2 year warranty Utra-high capacity battery Maximises time between charges Delivers superior performance Robust and durable battery Direct battery replacement Stable and safe to use No memory effect Capacity: 4000 mAh Supplied: 1 xEB595675LU Gold Battery And my results: (Settings: From what I recall, brightness was at 100% and NFC, Wifi, GPS and Bluetooth were all enabled.) Let me know what you think.
