I have searched the interwebz and found a lot of threads discussing problems similar to mine but none of them are having the same problem. Just wanted to get that out of the way so you do not think I have not already tried solving my problem.
My S3 have after a little more than one year of use now started draining battery at perhaps 10% units an hour even when it should be in idle. I downloaded better battery stats and found out that it never enters deep sleep. It stays awake the whole time.
According to BBS this is because of cell standby which keeps it in partial wakelock. This is weird since I have my phone in flight mode all the time and it should not be looking for networks at all.
This started happening 2 weeks ago 3 days after I had been at the beach. When I noticed the problem I thought maybe that salt or sand had damaged the SIM card. So I tested my SIM card and found that my phone can not find it anymore. Unfortunately I am in japan at the moment and they all have nano SIMs on their phones for some reason so I have been unable to test if it's the SIM card that is broken or the phone.
So my theory right now is that the SIM card is damaged and that somehow is making the phone freak out and burn battery looking for something that isn't there.
TL;DR Cell Standby Burns battery according to better battery stats even though flight mode is enabled. Phone can't find sim card either.
Has anyone had a similar problem or know what might cause it? As it is I can't even use the alarm on my phone since it dies within like 6-7 hours so I am always late for work
