After spending a few hours with the Lava Xtron+, I noticed that the battery was diving downwards at a ridiculous rate. This kind of usage was very strange, so I opened the battery stats page only to find that Cell standby had consumed nearly 65% of the battery. This tablet DOES NOT have any radio cells , even after turning on airplane mode it is consuming huge amount of battery, how to fix it?..Please read this review, this has addressed his issue
