Phone Radio uses 80% of my battery I have GSam Battery Monitor, and it says that my Phone Radio is using about 80% of my battery. Why is this so high? I usually unplug my phone in the morning at 8AM, and I usually need to plug it back in between 2PM and 4PM. Maybe this is normal, but it seems very high to me.
this sounds like you move in and out of data service alot. 4G was very new in ICS and radio handoff wasn't very efficient. even if you have a newer version of android, what i'm about to describe will still help. if you are in a location with secure wifi access and little or no 4G signal, turn off your mobile data to keep the device from using battery by trying to find a signal. the radio firmware will chew thru power searching for signal, even with the screen off. turning off mobile data has helped me save a lot of battery in the past. you will still able to call and text, as 4G is a data-only band. if your device supports VoLTE, turn that off as well. doing that will force the device to route calls over another band that uses less power and hopefully has better signal strength.
