Loaded an update from at&t a couple days ago and ever since my lightening charger will not charge my phone (says it is but percents steadily drops) and the overall battery life has been absolute garbage (last night it dropped 20% in 1 hr with NO activity). Any ideas what is going on or how to fix?

Next step should be to try a different charger and cable and see if those work to see if the thing is just bricked or not.

Don't have another lightening but my generic charger works on both 2.4 and 1.2. Still losing power way too fast when not plugged in.

I think I might have had the same thing happen just now. I plugged it in to my fast charger for the first time since Friday (use a normal charger overnight at home), and it wasn't charging fast or really at all.

I fixed it by going into the settings, turning off the setting for fast charge, then turning the setting back on. Seemed to fix it for me.
