Unfortunately, it happens to me then out of the question. When the battery is exhausted, I want to simply replace it. The permanently installed batteries are an environmental burden only for the sake of profit. One should just buy every 2 years or earlier a new device and not just a new battery. This policy, I will not support! If more customers would think so and act accordingly, then this nonsense would soon end. That there is another way, proves yes Samsung. However, only the Ativ S than Windows Phone on offer. I have been and am impressed. Just do not get the update to 8.1 just win. And I want another Windows Phone. Is better and more stable.
