Two days ago I decided that my z1c has suffered enough. It is already on its second battery and it lasted for 2 months with good battery then the problem returned. It can even shutdown at 86% battery and I cannot top 30 mins SoT...And if you think that is not enough, I also changed the USB port which died after 1 year and now it died again and it barely charges on magnetic now. Sony phones have great potential but is superseeded, as most companies are nowadays, by more budget friendly devices like Xiaomi, especially in my country. I decided to buy a Xiaomi Mi6 as it has a great price, good cameras and monster performance. R.i.p Z1c.
