I have seen a little on this, but I am not a techie and simply don't understand some things written (rooting, reflash etc ??) - new to the forum, loks like a lot of expertise here! I have ZT180 (ebay thing - came from China) 2.1 update 1 20101204 18.104.22.168 The battery is being eaten by the non-existent cell device - to the tune of 75% of the usage. If I can stop it trying to be a cell phone, I guess the battery standby would go from 5 hours (standby) to 10 or more - and I could actually use it . On wifi now, I am lucky if I get 2 hours use. I saw some instructions elsewhere but they seemed to be for other devices and I would need a PHD and an Android dictionary to understand them - so my question is .. How can I fix this - in a step-by-step newbie way Thanks all - a bit lost here! PS - no airplane mode even available.
