OK it's official! This battery is real. Following the 1st full charge, right now it has been running for 11h 49m with 7% (1h 10m) left. I turned off/on the ipod a couple of times after the battery was drained below 10% and there was no shut off whatsoever. It seems the battery is able to be drained to the last drop. LOL. The battery seems very resilient as it's drained low, and I think that's the good sign of a strong battery. The iBat is 75 mA while playing (no charging) with brightness at 16. Gear used to test the battery: Capless diymod with 480GB mSATA to UHA-6S.MK2/EX1000 (most of the time)/All playing 16/44 FLAC's UPDATE 1: Now running time 12 h 27m, battery reserve is 6% (1h). UPDATE 2: Now running time 12 h 47m, battery reserve is 4% (40m). UPDATE 3: Now running time 13 h 12m, battery reserve is still shown at 4% (40m). UPDATE 4: Now running time 13 h 37m, battery reserve is still shown at 4% (40m). UPDATE 5: Now running time 14 h 02m, battery reserve is at 3% (30m). UPDATE 6: Finally the battery was spent at 14h 15m running time. I am surprised with the results and I have certainly underestimated its power. With this battery and a 480GB or 1TB mSATA mod, you are golden.
