Hi all, I have a Zenithink ZT180 and I have noticed in battery stats that it is using quite a bit of battery on "Cell Standby - Battery used by cell radio" It also says to turn on Airplane mode to save battery and that it is unconnected for 100% of the time. As it has NO phone, the 100% disconnect is no surprise, how ever using battery for it is. Equally perplexing is that in network settings, there is no Airplane mode there is 3G EVGO, WCDMA and Wifi but no airplane mode. #G EVDO and WCDMA are off so what is the cell radio using the battery? and where is Airplane mode to switch it off?
