Hello, I have an iPhone 6s 16GB. From iOS 9.1 (I bought it when that version was preinstalled) I have battery bug which means battery percentage probably shows wrong value. There is no normal unloading battery for example: 88%->87%->86%. In my case it sometimes looks like: 50%->48%->47%->44%. Even without apps working in background or games. The worst thing is low power percentage. Battery drains very quickly. From 20% to 10% it can sometimes take less than 15 minutes. I have not travelled out of my time zone yet. The method with changing time to automatic does not solve the problem. I have installed the latest software available for user: 9.3.2. I have also formatted the battery once a month. Nothing helps. The newest version of iOS has the bug too. What can I do with?
