Is there a simple way to see the amount of power in percent or hours that is left in the battery on the Satio? On my previous phones, it was possible to push the volume button in standby mode in order to display a status panel, displaying my phone number, currently active ptofile, alarms pending and battery power level. The information exists there somewhere in the Satio, since it is shown in the PC Suite when connected to the computer.

I would like to know too, It's a big thing I miss

One other thing I miss is call duration time.

I don't know how to display call duration during the call, but after the call is finished, it can be displayed. It's in the call settings somewhere.

settings> calling> call> .... towards the bottom of the screen is "Show Call Duration"
and "Details after call" and I'm looking at the battery % one at the mo

I reject your reality and substitute my own.

The battery indicator under symbian is useless after the first 40% are gone because the battery will be depleted after 2-4 hours only
It's the case with N97,5800 and now Satio, the first 40% part can last 2-3 days so you say wooow dude I still have 60% after all!! be after only a couple of hours the red light will show up

It's like the gas meter in the car.

This is probably caused by a poor design of the measurement method for the battery charge. A correct measurement should be made the same way as the electricity power meter is measuring the 230 V AC delivered to your home, i.e. constantly measuring the current drained from the battery and integrate the value over time, and when 1000 mAh is consumed, the battery is empty. Instead of this perfect method, the power meter usually measures the battery voltage, assuming that it's proportional to the currently stored mAh:s. Unfortunately, this is not corret for modern batteries. Instead, the battery voltage is fairly constant between fully charged and fully drained, it only drops a little during that time, and then the voltage drops rapidly when the battery is almost drained.

But I still miss the possibility to see the power status in digits instead as a green or red graphic battery icon.

there is no way to tell how many hours usage you have left on a device like this as it will depend on your usage over time, seeing the battery indicator would be useful though

Of course, the calculation of the time remaining can only be an extrapolation based upon the current power consumption. It's the same reason why it's pointless to say that a mobile phone has 300 hours standby time. Try to make a phone call after having had the phone on standby for a week....

Haven't seen the homescreen of the Satio but if it's like other S60v5 stuff (I've got N97 - doh!) the meter shows how much "anticipated" usage you've got based on current usage pattern. Which is batty cos if it's been doing couple of SMS's and just sitting around for 3 hrs and then you check before you take it into the car for example, if you then turn on the GPS then you have much less power than you were originally indicated.

It does not make real sense to measure power in hours. It should be a unit for power or energy, like Ah or W. Or a percentage of fully charged. It's the same with the gas meter in a car: Measure the amount of fuel in Liters or Gallons or percentage of full tank, not in Kilometres or hours. An on-board car computer can calculate how far you can travel or for how long time you can drive the car with the current amount of fuel based upon the current speed and fuel consumption, though, but that's something different, and the calculation will be incorrect if you suddenly change the speed, or if you change from going uphill to downhill, for example.

Whether it is possible to show hours or not is not the point. The point here is to show a proper percentage.

How come other phones are able to show a proper depletion rate ?
How come previous Sony phones (in UIQ) still shows a constant depletion rate by percentage ?
Why can't we use the same calculation methodology ?

I know this phone is on S60v5 and I do not what interfaces available from S60v5, but from user point of view, I would expect to see constant depletion rate rather than slow depletion till 60% and then suddenly the rate increases and the battery is gone within 3 hours.

That is exactly what happened with me. Yesterday morning I saw 50% and thought since it took 1 day to eat up 50% it will last. Suddenly at lunch time the phone went black and no battery !! I would have thought with same the rate of battery usage, it would have lasted another 1 day. It did not do.

So what ever is the argument, one point I can still say that SE needs to improve the battery meter and battery life for sure.

I'm not sure that I expressed myself clear enough. I fully agree with you, I want a proper battery indicator too, preferably also displaying the percentage with digits.

Then, I was only trying to explain the difficulties with calculating the correct value for the meter. The problem lies in the voltage/charge ratio curve, the slope is almost zero (i.e. horizontal: the voltage is nearly constant) all the way until the battery is almost drained, and then the voltage falls very fast. This makes it very difficult to calculate charge level based upon the voltage with a fair accuracy, and the effect is usually as you describe, a slowly decreasing charge value until the charge value suddenly drops very fast and the phone dies. It would have been much easier if the ratio curve was a straight line with a constant slope, but I don't think someone would want a battery with that characteristics, i.e. the voltage decreased to half when the battery is 50% charged.
I can imagine that it's too expensive to use more advanced methods to determine the charging level, like the methods used in laptop batteries. On the other hand, I find the accuracy much better in previous phones I have used.

I know u can see call durations at Logs, but that I want is when I speak at the phone, it dosent show anything only calling ..
