How I can completely kill the phone signal, telling to Android that the phone is just a tablet, so it doesn't even try to bring it up?
Sorry for the strange question, but I have bought a BAD ESN from America for using it as a GPS device and multimedia player in my car, but the battery on standby is really bad.
I have a Samsung Galaxy Chat and I am using it as a working phone, so when it is on standby wifi is disconnected, no data etc.
It does have a tiny battery but on standby it runs for much days without depleting the battery.
But on the Spring Galaxy something is really wrong. Before downloading a Spring Diagnostic app and turning as much as possible off, the battery would deplete in one night (100% to 15% in 8 hours...). Now it deplete a 15% in one night, but it's still too much.
I tried in the past weeks to uninstall phone.apk, mms.apk, telephone providers, setting hw.nophone to true on build.prop to true... But it only killed the phone settings and I couldn't even switch the phone on airplane mode, so the battery was still depleting really fast.
Any idea? I tried on stock rom, cm 10.1 and now on paranoid android.
I noticed that the Samsung Galaxy tab 7 is just the same as the Galaxy nexus... It could be used something from there? http://wiki.cyanogenmod.org/w/P3110_Info
