Does your WiFi stay up after waking up from sleeping?

Seems that my G2 doesn't always "re-connect" properly when I wake the phone up. My G2 is already setup to "Always" within the Wireless WiFi Advanced setup. Is this a common problem with G2s?

Mine does. May be a problem with your kernel

Mine sort of had that problem but then I just changed the wifi sleep policy so that it never turned off.

And you get better battery life in the bargain as well. Definitely a win/win.

Battery at 48% after 17 days and 18 hours without charge.

Hey guys,
I live in the uk and went to Bulgaria for 16 days. I left my S3 home and took an older phone with me. Didn't want my samsung stolen, etc.
So, before I left the house I charged the phone up and left it in airplane mode.
I got back more than 2 weeks later to find the phone still on in standby mode with 48% of battery left. Meaning that it could go for about 34 days in airplane mode with one charge.
I know we can't do much with this info but I felt the need to share it.

That's awesome. My sgs2 can only make it for about a week in airplane mode, with a 2100mah extended battery.
Are you using the stock ROM? Looks like touchwiz icons from the screenshot you posted.

This is completely useless... But very interesting ha ha
I wonder how long would it go without airplane mode on

I could've told you that from GSMArena's spec sheet
Stand-by Up to 590h/25days (2G) / Up to 790h/33days (3G)

We need to know your rom version !

There is absolutely no way it could go that long with the radio on. Mine was in airplane mode.

Everything is stock unbranded uk. Still on ICS.

So in order to get great battery life all we need to do is never turn the screen on and never use it as an actual phone, great find!

I bought my s3 from cex (a popular exchange chain here in UK) and when I got the phone it was at 8% charge with 34 days of standby. The phone was left on, without sim card inserted, but with WiFi on, even if wasn't connected to any network. I thought it was pretty cool as the same happened with a one x I bought two weeks before, always from cex, and in the same condition the HTC was on 8 days standby time when it discharged completely in my hand

Nice!!!

Actually there is a point to this...
I think that this is a very interesting post. Why?
Because I suspect that for most people, there are times of the week when they don't actually use the phone or even need it available to take calls but (like me) don't want to have to turn it off at night and turn it on again in the morning.
So, using a tool like Llama, you can set your phone automatically to put itself into Airplane mode at night and to reconnect in the morning - so extending your stand-by time.
(Note: I actually go further than this - and put mobile data on only 3 minutes every 30 when screen is off. And I get great battery time - or would do if I didn't use the screen so much!!)

Too many wake locks
《swagged from aokp》

Well, I have lots of apps installed. Could have last much longer after a factory wipe I guess.

My old smartphone with data and radio off could last about a week at most.

Daylight savings time weirdness

So I had a writers thing happen and wondered if anyone else had it or could explain it. I woke up yesterday morning at what was actually 12 but my phone said was 11. Sometime during the daylight savings time change my phone fell back 2 hours instead of 1. It's right now, though I couldn't tell you how long it took to right itself or what time it was right. I'm on CM7 with xboxfanj's nexus modem kernel if that matters.

Welcome to the Samsung Epic4G and Sprint. Happened to both my Epics last year and to my GF's Epic this year. A reboot gets you to the right time.

Happened to mine but my phone was set to Central time and not Eastern happened to both mine and my wife's phone this year.

It worked for me on the same sw. It can probably be fixed by unchecking automatic time and rechecking it. That's weird though.

Mine went back two hours as well. I noticed it Sunday morning when my alarm clock didn't go off at 6:00 AM. It corrected itself sometime around 8:00AM, without a reboot. I was wondering what happened as well. Oh well, all is better now.

WiFi keeps turning on

I purchased my S4 2 days ago, so far I'm loving it. However, for some reason the wifi keeps turning on even when I have the setting turned off (I get a decent 4G signal where I live & would prefer to use that when possible). Any ideas? I'm rooted with the stock ROM.

Do you have the "smart wifi" setting turned off? It is the first option on the wifi screen, tap it then turn it off and you should be good to go. If you have already done that then I'm not sure.

Cache Update Service not letting phone deep sleep

It is a Google service and I have disabled location services and Google Now. Does not seem to make a difference. I have looked everywhere and have come up with nothing. I have the phone set up basically the same apps as my N4 and my Nexus is crushing my G2 in battery life. Any ideas would be great on what is causing this.

Are u talking about google service that you see when you go into battery usage options? If yes, im in the same boat as you.
What percentage of battery doew the google service use?
I would like to know how to take care if this problem as well

I am using better battery stats and it is partial wake lock I guess I did not bother looking at the overall usage. I am trying a few more things and will report back later.

add me to the list of people this is driving nutzo.
Question, when you go to google sync under settings/accounts and sync, does it show that 'sync is not available at this time?'
I wonder if that could be causing it?

I am waiting for my case to make it my daily driver but last night I tinkered and went and set up all my Google apps and changed my Google plus photo to only upload on charger. When I turned it off it was deep sleeping and and that wake lock was no where to be found. If anyone wants to try this and see if it helps.
