    2 days ago I OTA updated my device to 2789 OS. Yesterday I stayed all the day at home and I noticed that my device, a Z30, worked incredibly good; furthermore, the battery drain was as good as never: at 9pm, with an heavy usage, I was still at 50%.
    Today, on the contrary, I've noticed an almost opposite behavior: after less than 3 hours my battery was at 75% without using the device.

    How it is possible? The only difference is that yesterday I was connected all the day with my home wifi while today I passed all the day outside.

    That is the difference. Inside you were connected to wifi with a strong signal. If by outside you meant that you were not near wifi and were on the network, then differences in signal strength can affect your battery life. If you were outside and close to the house, if wifi is turned on in your settings, the phone can be trying to connect to that signal first, even though it may be weak. Then when finally you are not close enough to connect even to a weak wifi, the phone will then connect to the network.

    I loaded the new OS thru blitz and then unchecked "only load newer apps" on Sachesi and loaded the .799 radio file. It has worked a little better for me for network strength and the same for wifi. Phone calls are clear with no issues.

    Thank you but this is not a real explication. I mean, what you told me is that the heavy battery drain could be affected by the continuous pursuit of a wifi or of a strong network signal. Right? I already know this thing and, for this reason, I normally turn off wifi when I'm not near a known wifi. What is not 'natural' is the different battery drain. Before 2790 radio I've got 841: good battery life and very good signal but battery worked both with wifi or without wifi in the same way. Now, this is completely different. If I turn off wifi at home, where normally I have a very strong LTE signal, my battery start to drain very fast and this thing doesn't have an explication; but, if I turn on wifi, it begins to drain very very slowly

    Strange battery behavior-img_20151003_123956.png

    This is the body of evidence. In the first hour I used wifi connection and my battery 'lost' only 3% of charge; in the second hour, without wifi but from the same position and with strong LTE signal it lost more than the double, passing from 97% to 90%.

    How can I explain this?

    It is said, that the OS has to settle after update. It takes some days. Then you get full potential!

    Yes, this is what I thought. I hope you're right but this kind of issue is the first that appears since I update my device radio

    Cellular connection uses way more power than WiFi. So. If you have accounts and apps that use data all the time, what you experience is normal

    Yes, this is what I thought...but why 841 radio, with same configuration, works better? I mean, there is no difference between wifi or LTE

    If you suspect that it might be the radio... change back to 841 or 859 radio... see for yourself and let us know what happens next!

    You were right! Normally I will have changed radio file but now the device looks incredible: it's far more faster and battery life is absurd. Thank you guys

    You can do some math. The maximum power output of the radio I think is 1.6 watts when it has zero signal. If you know the capacity of the battery you can divide it and get an approximate percentage. Other losses will be screen, cpu, etc. It is not unusual if you are a commuter or work in a concrete building to have your battery drain.

    Also on a day to day basis conditions outside change. More towers, less towers, less people out, more people out, etc.

    Better to just measure the overnight idle performance while you sleep at home. And while commuting to see if you have more or less dead spots than before.

    After I multiwipe I tried a clean installation of 10.3.2.2789 and nothing changed. Under Wi-Fi battery life is gorgeous: with an heavy usage I could arrive at the end of the day with more than 40%. On the contrary, without Wi-Fi, at 3pm my battery already at 60%.

    This morning, in less than an hour my device has passed from 100% to 92% without using jt.

    When your WiFi is turned off, do you have Mobile Data enabled? (3g/4g/LTE)
