Can someone weigh in on some of the pros and cons of this update. From my point of view it will actually save battery to have wifi always on in standby mode, but I could be wrong. Initializing a wifi connection costs more energy than to keep it alive in a standby state. I'm a new WP user so I do not know if before for example, you were listening to online radio and locked the phone, would it eventually switch to cellular data or continue on wifi?

Here's what Microsoft has to say about this on the Windows Phone web site:
"If you want your Wi-Fi connection to stay on even when your screen times out, in Wi-Fi settings, tap Advanced, and then select the Keep Wi-Fi on when the screen times out check box. Your phone can then use a Wi-Fi connection even when the screen is off. This uses battery power, though, so your battery life can be shorter compared to when Wi-Fi turns off when the screen times out."
They're saying keeping Wi-Fi on uses more battery power, so that could be considered a con.

I dont think it will consume more battery. Previously, when your phone sleeps, the wifi disconnects and your connection goes back to data, so you are still using data, which does consume battery. Honestly, you dont have to be worried either way, battery will be consumed in idle mode, but very less, because you have an option to close applications in sleep mode.
Regarding the update, it is definitely welcome. It is always better for the use to have control. I have a few friends who dont use data at all. They have a 200 mb data connection, and they switch on the flight mode and use google voice and wifi. So, it was increasingly fustrating to see their wifi being disconnected when the phone sleeps.
As for myself, I use my office wifi, but can use it only after I authenticate from the browser. So every time my phone sleeps, I had to authenticate from the browser everytime.
And as I said, I would prefer that the phone uses my wifi during sleep mode than my data connection.

In the past, if you started downloading updates from the market while on wifi and the screen turned off, they would stop, because the wifi connection would drop. There is also the issue of your cellular data being consumed for e-mail, notifications, etc. whenever the screen is off (and thus Wifi).
I don't think it will consume MORE battery because the Wifi will now take the place of LTE when it is on. LTE consumes much more battery. Unless Microsoft didn't code the software to prioritize and disable connections that aren't in use. That's how it works on the iPhone and most Android phones. If Wifi is on, the cellular connection is not being used, so idle battery life is actually better.

Of course having WiFi on all the time will consume more battery if you are not actively transferring data. Think about it, you have an extra WiFi radio actively listening to all the packets in the air constantly! Now, if you ARE transferring data, say streaming music, then yes, WiFi will save battery compared to 3G/LTE which requires more transmit power. Problem is people just leave it enabled all the time even when they are not using data actively. During that time, you are wasting more battery.
There are, however, times when always-on-WiFi is handy. Xbox Smartglass is one example because it's annoying having to reconnect WiFi every time.

I was always able to have my Wi-Fi connection always on, even before the update (and I know this because I was able to get push notifications ALL the time even though I always turn data off when at home). So I can say that in terms of battery usage, it does not do much harm, my record so far was keeping the phone going for 3 days with LIGHT usage, and 1 - 1.5 days with normal (medium) usage.

Well, I used Android for two years. I always use Wifi when I 'm at home. Cell data uses more battery than having it on wifi. Because with cell data, you're using service and/or searching for signal.
With Wifi on, it's just..on. Once you're connected to your router, that's that. You don't have to worry about connecting or find a signal. (Unless it's a call or something, but that's a given)
Texts come in through wifi. Notifications, etc.

Where I work I get at best one or two bars of edge service. All my apps would update like every 30 minutes but would fail because it would take too long to update. During this time they are consuming battery for the entire time of their update attempt. On the other hand with Wi-Fi connected these update take about 2 seconds, hence saving battery.

When Wifi has a constant connection, it helps battery life. When it's on and not connected, it adds a little drain. I have been using my Note II for a week with no Wifi access and its has been significantly worse on battery than when I leave Wifi on all the time. It has to rely on the LTE connection and that is much harder on the battery.

It's been interesting reading everyone's thoughts on this. I think what I'm going to do is enable the new Wi-Fi always on feature only when I'm downloading stuff or streaming music at home, where I have Wi-Fi. Otherwise, I'll leave that feature off. For me, those are the only scenarios when the screen would time out while the phone is doing something. I don't get that many e-mails (only one account and set to check hourly) or notifications, so for me it's not that big of a deal if my data connection is used for that while the phone is locked. I don't know much about these things, but to me it makes sense that having the Wi-Fi radio on all the time, when it's not doing anything, would consume more power. When I'm out and about, I have to use my data connection since there's no Wi-Fi available (few public hotspots in my area), so, for me, it seems totally unnecessary to have the Wi-Fi radio always on. When I'm home or somewhere with a hotspot, like my local B&N, it only takes a few seconds for the Wi-Fi to connect automatically, and I don't mind waiting those few seconds. At home, the phone remembers my Wi-Fi password, so I don't have to enter it each time I turn the phone on. If I did, that would be such a pain, and I would definitely leave the connection on in that case. I'm seeing that there's really no right or wrong here; it's whatever works best for each person's particular usage.

Im lazy and I don't want to turn wifi on and off and keeping it always on will consume more power, so I will just keep it off and use LTE for everything. I turned wifi on once or twice since I got my phone 3-4 weeks ago and that was to sync photos to Sky Drive, I wish they would allow us to sync photos to Sky Drive at full res over LTE, what's the use of having LTE if they cripple it like that?
