My phone was working fine until the most recent update (within past 2 days). Now battery life is terrible: I used to go 1.5 days between charges and yesterday my phone died by mid-afternoon. This morning, I'm at nearly 50% after only 2 hrs of minimal use. Phone is less than 2 months old.
Can I revert my phone to its pre-update state? And can I prevent the auto-updates?
