Help Battery problems, drains too much on standby

[Aemasil]

So all was well with my phone and I could easily get 1day+ worth of battery time out of it, then one day (sadly can't remember what I did) it changed. Now I'm lucky if I can get it to last 10 hours on standby, 5-6 hours with minimal use. I've tried factory reset, battery re-calibration, alas to no effect.

So now I seek help from people brighter than me who can hopefully tell me what's wrong and the obvious easy solution (please!).

These are images from the phone, with no usage.

Having same probl but unable locate reason. However after changing DTIM in my DIR-655 router to 50 iso 1 things approved. Setting 255 possible but destroyed reminder of my wifi system!!Still recon this as an tempo solution but still next change will be a new router as the DIR-655 seems to cause this type of probl among many other operators. Looking fwd to your trpoubleshooting/actions !!

Thanks, but, eh, I'm not sure WiFi is the problem as the phone drains equally much on 3g.

Nothing overly bonkers going on there it seems.

I would definitely put the wifi sleep policy to "only when plugged in"

also, try charging to 100%, take out your battery for 3 minutes. during this 3 minutes, keep the power pressed for at least 10 seconds, and when you insert the battery, press power+home for at least 10 seconds.
