It happend allready that my iphone 6s switched of automatically if accu is below 20%. Ill try to work and suddenly screen is black. To get it back to work it is necessary to connect to loading adapter. if it is connected the battery will be displayed on the screnn and is flashing red for complete unload. after a few minutes iphone is back at 20% or more in battery charge. Someboy any ideas what can help or what is wrong?
