after above mentioned update my battery life decreased for about 80 %. And it says that most of the battery is used for Android system. Before that (first update on Nougat) I was able to get two days without charging, now it is on 15 % by 8 pm after night charge. Anyone having similar experience?
Hmm. No, something must be wrong in your phone. Probably an app eating up the battery. My battery life isn't excellent, it has never been, but with the last update it seem it did improve a bit. I'd suggest to install GSam Battery Monitor. The good news is that it doesn't need root, but you have to follow the instruction to grant the permissions to it via "adb" using the computer.
Once installed and enabled you can check with it if any app is misbehaving. It's a very neat app, quite complete for this purpose.

Yes! I certainly am having a similar experience, and I hadn't really thought too much about the individual updates but for me it seems to have been since around the time I installed Nougat 7.0.
When I first got this phone (just 3 months ago bear in mind) I could easily get 2 and a half, even 3 days out of it. I was amazed by the battery life, and I know that batteries deteriorate over time, but within 2-3 months?! Surely not. Anyway, I now notice that I've gone from getting 2-3 days, to much less than 1! For instance, I took my phone off full charge (100%) at 8AM this morning. It is now not even 11AM and I am down to 75% and I have barely done anything on the phone. I now have to charge my battery every night, which I am not happy about, especially as the so-called Battery Care feature is useless and doesn't work either!
This phone is fast becoming a massive disappointment to me - when I first got it and it was on Marshmallow 6.0, I loved everything about it, but true to Sony's usual form, they insist on messing up their flagship phones with terrible software updates.
Like you Andro43, I'd also love to hear a solution to this battery issue - I have checked in Android battery settings and can't see anything obvious eating the battery.
I suggest, as first step, to clean the cache every time before plug the phone to charge. I also noticed a little decrease of battery life but in this way I can reach 2 full days with one charge with less-moderate use.
Today Phone Arena site also reported about this tip to improve the battery life. Smart Cleaner service is all without "smart"; it don't give notifications, it is not personalizable to what clean and the frequency and someone found it very very useless.
Let us know if the clean of the cache helps you.
Reading your report I have two suggestions for you.
First, in the options of Wi-Fi section, let control if you have enabled the "preferred network" and "continuying scanning" options.
Second, in the locations section, under 3 dots, let control if the two voices are disabled.
I hope these tips can help you, really!
