I work in an Aluminium Smelter, we have a large amount of electricity running through our furnaces (pots) and this creates some pretty intense magnetism.  When i have my phone in the potlines the screen goes black showing only the time,  unless I hold it at a certain angle (maybe somebody can explain why?).   Since I have been working here (just over 5 months)  my Phone's battery has been having issue,  running flat quickly and taking 7-8 hours to fully charge from flat,  on flight mode (was told flight mode makes it charge quicker).  So if somebody can tell me why this is or is it a coincidence?

Phone battery running flat, not sure why. Should I be worried or is there some other angle I can use to

My phone's battery is constantly flat on flight mode, can my phone be affecting this? EDIT: I have tested my phone
