I've had my xr for 2.5 months and for the first 6 weeks or so the battery was utterly fantastic; I would take it off charge at 6am on 100%, leave work at 5.30pm and it'd be on minimum of 75% and would easily get through until 8pm the next night before nearly dying. Now, with the same usage, I'm doing the same but leaving work with ~65% and the phone needing a charge by 12pm the next day - to me, that is a massive degeneration and I cannot understand why. It loses 7-10% overnight by simply being sat in my drawer whereas when new it would go down by 1-2% max. I get that after a year or so the battery life is almost non existent as that is what happens with iphones, but to degenerate this much after 10 weeks? Has anyone else noticed a similar issue?
