Can someone explain why the battery estimated is less when battery stamina is activated?. I thought this feature is meant to save battery!?

The simple answer is I'm unsure. When I activate it my standby shoots up. Have you added any apps that can still sync even when stamina is activated?

I get the same thing after enabling/disabling stamina mode. have you ever used your phone while stamina is off?
I think the phone is optimized for stamina on and not really optimized while stamina off (I always use it while stamina on). Thus the estimated time with stamina is more accurate (depending on your usage) compared to the estimated time while stamina off. to test that, use your phone with stamina off for couple of days until it is optimized and you will get better reading, or use your phone until it dies and see which one gave more accurate reading (once with stamina on and once with it off).
How does stamina work exactly?. As when I have it enabled the 3G or Wifi signal never disappears in the top right!??

Eg.. When I flick the power button and the lock screen is showing my 3G/Wifi symbols r still there!

Hi guys,
I'm having a kinda weird problem with the battery meter on my xsp sometimes the battery level magicly goes up again

I think it's happen on all XSP, because my friend XSP has that too. As far as I know, it happen because when you don't use it, it starting to lower the CPU frequencies so the battery use is become smaller than before

And it happens if phone is hot then cools down, then indicator guess up.
As long as it is only 2-3% it is nothing to be concerned about
Sent from my C5303 using xda premium
Yes, it happens on almost all the devices. @Pulsa However I don't think the cpu voltage can be so low that it makes a negative battery use (we speak about the battery getting more charge than before). I suspect changes in temperature between use and standby to be the cause but it's only an assumption. We need some physicists here

Yes,therefore I set it in quotation marks I just didn't know how to describe it otherwise
Problem you described happend on my S+ too. The problem was a faulty battery gauge. To solve this fully recharge it and let it slowly discharge by using it..
With removable batteries you just clean it and done. But with the XSP this is not possible
My power management in my xperia z1 is having issue, i always need to clear data on eco mode controller and restart my phone to fix this problem because of inaccurate hours left.

Same here, with 4.2.2 I had like 17 days in standby but I saw when I reboot my phone, the time left switch to less like it will calibrate him self. To me is inaccurate anyway, there is no way to keep you phone alive so long like it show you so I will not be bothered about it. Make a calculation on your own.
I thought ur phone is already in 4.3?

Yes, it is. I was just saying was even worse with 4.2.2 but no big changes even on 4.3.
What I'm wondering is, how do you people know how many hours there should be left?
Does it not calculate this depending on the data you supply it with (your previous usage on cycles it has monitored)
Mine showed pretty low numbers very early on since I was fiddeling so much with it that the battery was flat pretty quickly.
Later the predictions increased, since I started to use it a bit less..
If you delete all the info it has to go on all the time, how will it be able to give you correct output?
how long does your phone last usually?
You say inaccurate, do you mean it shows too many or too few hours left?

In my case it shows always more than what he will really be on battery. This was with 4.2.2 and still with 4.3. You right about how it work and how the calculation are managed but really the calculation are untruthfully. I will never take in consideration what the phone saying so this was my only advice.
In my case my battery drains more if my power management malfunctiond and it bothers me..

I have bought XZ 2 days ago, I recharged it first then updated to 4.2.2 and now recharged 2nd time, i unplugged my phone amd after 30 minute there was only 97% left.. Phone went into DS. Any ideas why it has got such a big drain. Wifi and data was off.

I don't know but you can delete some bloatware which produces wakelocks with a root browser or titanium backup.
Check the apps betterbatterystates or wakelock detector.
You can also turn on stamina mode in settings.

Are you using LTE? I get noticeable less battery drain when I'm in a poor LTE covered area and force the device to run 2G/3G.

Give Wakelock Detector a try, it's the best way IMO of seeing exactly what's draining your battery:

try! completely discharged from 100% to 0% then charge 100% full or try stock 4.3 clean install
Stamina mode gives me 1 day and 7 hours and without it it's 22 hours, is this okay?

it depends how u used your phone during on battery time.
I don't use stamina mode and I get all day out of one charge. Depends how heavily you use your phone. Try it, experiment a bit and see what works for you
Stamina mode benefit is somewhat situational. If you always turn the screen on it won't kick in to that mode as much. If you whitelist apps that do a lot of frequent data transfer it will help less. If you are in a poor network area it will help more while the screen is off for a while.
Makes it really hard to set a standard of what the battery life should be...
I use my phone moderate I think, some heavy usage in a day, but not much It gets me through the day, sometimes not the whole day and I'm after an update 4.3, but in the last one it showed me on stamina mode like 2 days maybe

You have to make minimum 10 cycles from 100% to 1% to let the system set up properly and the Stamina to calculate your usage. If you Update to .136, you will have same problem again because the system have to start calculate your usage and battery life again and you will have to make another 10 cycles from 100& to 1% and charge to full.
Cool, I will do that

This 2% per 5 mins is when the phone is in standby mode ?
then there is some crap that is eating all your battery.
have a look at the battery usage and see what is using the battery most, in my case it's exchange service -- i cant do anything there because i use email app to get my office emails.
please reply with the app that is using most battery.

I don't think it'll matter.
Looks like your battery is dead. This phone is the most power-effective phone I owned since Motorola Defy+, it can hold any abuse and still has juice at the end of the day.

And then you've either installed some app that keeps your phone constantly awake, or killed the battery immediately by discharging it to 0. That's the only 2 explanations.
Right now I'm 17h on battery at 50% remaining, and screen as the top discharge reason with 32%. My father, who doesn't use the same phone extensively, routinely charges it once in 2 days. You should have screwed up something really bad to cause this phone not to hold charge.

Could be killed battery. This app won't do anything bad, I believe.
Might also be something reception-related, but I'm not sure if the reception is good/bad or if your carrier does/doesn't support fast dormancy and to what degree does it affect the phone.
