STAMINA mode problem (?)

HeartBle33d — Sun, 18 Jan 2015 22:58:05 GMT

Good evening.
You see, I have this situation going on that I don't know if its normal behaviour or it is actually a problem. Allow me to explain.

About 1 week ago (when I bought my z3c) the battery level widget (built in) told me I had around 4 days of battery charge on stamina mode when the battery was at 100% charge. When it was at 14% I decided it to charge it, but then when it reached 100% again, the widget told me I had only 24 hours of battery charge. At that point the behaviour was only natural, since perhaps all the software I'd installed (launcher, lock screen, etc) was draining huge quantities of battery. So I uninstalled all my software (basicly leaving the phone in a factory state) and yet the widget kept telling me I only had 24 hours of battery charge at 100%. Then I decided to do a complete factory reset and voila, when the phone was at 100% the widget told me I had around 4 days of battery charge.

Now in this cycle, I decide to install all my software again (while still at 100% and connected to the charger) beign super careful of what apps could be the culprits of last time behaviour (I decided to leave aside launchers and lockscreens). Once I finished (still at 100%), the battery widget still told me I had 4 days of battery so I've concluded that the launcher and the lockscreen was messing with the battery levels. So I unplugged it and start using it till it reaches 14% again. I charge it again to 100% only to find that the widget tells me I had around 24 hours of battery charge (yes, the same problem I had before). I might mention here that in this entire cycle, mobile data, location services and 4g where tuned off.

Frustrated like there is no tomorrow, I decide to make one final experiment and try to figure what could it be the problem. I reset again my phone to a factory state and I leave it without apps, just the built in ones. And again, at 100% the widget told me I had 4 days of battery charge and when I re-charge it to 100%, the widget tells me I have 24 hours of battery charge.

Can someone tell me whats going on? What I'm missing here? What could be the problem? How do I fix it?
Thanks so much for your time.

The widget is an estimate and is based on your usage over around 2 or 3 days from the same amount of days prior - So if in the present you are a light user then the widget won't say this as it's giving a time from days before however in say 2 days time from now what you did in the now will be seen as your estimated time now,

Sounds confusing

This is quite a story.I suggest you try this: first disable stamina,then go to settings-apps-all-eco mode controller,force stop and clear data. Restart your device and enable stamina. See how it is.

That would be the logic behind my situation. However, here is something I don't get.
I'm at 100% levels and the widget tell me I have 24 hours. I do a factory reset and still at 100%, the widget tells me I have 4 days (sometimes 2 days wich makes it more confusing). Is it because all the registry on the phone got cleared up in the facroty reset?

On my next cycle (4th one) I will try this. Thanks so much for the tip.
By the way, do you agree with Thommo answer?

If you have done a reset then the time shown is a generic time untill it settles down and can give the estimated time starting from when you reset but again the time probably won't change for about 2 days

That is the genuine answer from Sony when I met the Sony developers and asked about the widget

Thanks a lot for all your comments.
You have solved this mystery and returned me some mental sanity.

I agree with Thommo,it will always display the usage from the past (a couple of days). It might change after a full charge and a different way of draining the battery or after a restart.
