Hi, got a very strange one here.
M2 MBA on 26.5
Noticed that the battery has started draining quickly. However it's not consistent. I've attached the stats.

Nothing unusual in my usage (just safari on a handful of sites) in either period as shown. Just dont get it at all as to why after resuming from sleep it drains much quicker. Checked processes and nothing looks strange.

Any ideas of where else to look?

Thanks.

Activity Monitor certainly.

In real-time it’ll show good information on the CPU tab. But the Energy tab can give clues even when the drain isn’t happening “right now.”
Thanks , yes been through all of that (it shows safari using power unsurprisingly). But nothing untoward hammering it.

I just dont get the difference in how quickly it drained this morning over last night with identical usage.
 
Safari extensions or plug-ins would be my first guess.

If you don't have any, restart the Mac and then launch Safari while holding a Shift key, to get a clean load.
