Samsung are not recognising that there is an issue with cell standby on the Galaxy S3.
Everyone who has high cellstandby battery usage, please sign so we can send them a list that proves it is widespread.
We need to know if this is a reporting error or if the baseband really is using this much battey. Battery life in general is good so it does point to a reporting error
----EDIT------
To clarify, this is not causing your battery to run down faster. This is just a reporting of the % of use incorrectly. Fixing this will not cause the phone to last longer. Please understand this. If your battery is running down fast, then you need to use a 3rd party app to find out what is using the power. The battery page wont help as it says its cell standby, but that is wrong.
