How long does it take before AccuBattery's stats are in the right ballpark? The reason I ask is because I have just installed a replacement battery (from a reputable store, but an unknown brand) in my phone and I am using AccuBattery to make sure that the capacity is approximately what it said in the listing. I deleted AccuBattery's data immediately after installing the new battery. Then I charged it from 29% to 99%. At 80%, AccuBattery said that the health was 53%. Now at 99% it says that it is 63%. However, the capacity estimate in the charging tab was jumping up and down all over the place as the battery was charging and is now at just over 2,500 mAh, which is about 90% of the expected capacity. I didn't get this kind of way off readings and wild fluctuations on previous occasions when I installed batteries bought from the phone manufacturer's official spares dealers. Those batteries consistently showed capacity right from the beginning, according to AccuBattery, that was a little way short of the nominal capacity.
