I am a bit unlucky and my battery became faulty. Batteries do not last for ever but shouldn’t get bloated at all. But it can happen once in a while and the battery should be replaced under warranty. I understand that. Bloated batteries can happen if battery is faulty (my case) or if they get too hot due to overcharging (unlikely in my case) or to warm surroundings (not in my case).
The problem lies somewhere else though. I do not get an answer to my support request. Meaning since a week I am waiting for an answer and until I will receive one and until I get a battery shipped there will be more time going down the drain. several weeks without phone is not acceptable. Cases like this should be handled within a few days incl. shipping. Lets see if I get an answer any time soon.
