[Android Q&A, Help & Troubleshooting] mr72:
This was an interesting hint. I tried this, but in my case it didn't lose the IP address.

However, my guess is that in your case, you are losing the DHCP address and the phone is reverting to another DHCP-assigned address that was cached on the phone.

But it led me to investigate this issue further on my phone. I discovered that when my phone is in this screwed-up state, I show link and everything looks good, ifconfig shows what looks like a valid address on my phone, but I can't ping the gateway and the arp table has an "(invalid)" entry for the gateway.

I am familiar with these issues related to DHCP and ARP in Linux, and I am going to look into how this may be fixed. I noticed on my wireless router at the house, the DHCP lease time was "forever". I changed it to 30 minutes. I think forcing a lease renewal may improve the issue for me, that at least in a half hour it will refresh the arp table and get a new dhcp lease.

Anyone familiar with Android and ARP/DHCP issues, if you are interested in trying to debug this problem, please PM me. Otherwise I am going to dig into it in some spare time and see if I can happen upon a solution. For the time being the DHCP lease expiration may improve it for me, I will see.

I was not trying to be a pain, just making sure. The app itself does not make this obvious IIRC. BTW my Burst never seems to get to 4200mV but my NC will charge to 4202mV. And I have also noticed that my Burst will get up near 4200mV and stop charging, wait to drain down 50 or so mV before it begins to charge again. So it can be finicky to get the stats just right.

Yeah I would disable it for now. I don't think it's helping any, and I know that if everything is working properly you should be able to get 12+ hours of normal use from one charge without resorting to CPU tweaks. For a phone, which is in your pocket asleep most of the time, these things make little difference anyway. On my NC when I am reading books with the screen on for 10 hours straight on a transatlantic flight, it makes a noticeable difference.

Yeah I deleted or disabled many of these from my phone.

I think if you redo the calibration it will probably work better. Otherwise you may have a defective battery. Or I guess it's possible that the BatteryCalibration app is not actually resetting the stats, so you might boot into recovery and wipe the battery stats manually once the phone is charged to 4200mV... just in case, last ditch, before calling AT&T and getting a different battery.

I ended up manually editing my ipconfig in data->misc->wifi

I do believe it was a dhcp problem. For some reason in that file there were several characters that I can only assume were korean.

Not sure if that's what fixed it for me or if my router was having a seizure.
[Android Q&A, Help & Troubleshooting] mr72:
Well for a couple of hours now my phone has been working on wifi at my house ok after making a couple of changes to the router, notably changing the DHCP lease time to 30 minutes, formerly "forever".

My suspicion is that there is some kind of DHCP snooping going on in order to populate the arp table on the phone, and since there is no DHCP transaction within some time window while the phone is asleep, the arp entry goes stale and the phone fails to connect to the gateway. Changing the DHCP lease time will force the issue of DHCP translation. If this were a Linux system I'd put in a cron job to do a gratuitous arp every so often while on wifi, but I don't know precisely how to do that on Android. If my DHCP change doesn't work, then I'll investigate this.

And regarding battery, for those interested, I have been up and using my phone off and on for 3.5 hours and change today, battery is at 93%. 2% per hour! Pretty awesome. I haven't made a phone call but I have done a little web browsing and fooled with configurations. A phone call or a lot of texts will suck down the battery much faster, but with minimal use or idle it will go 2%/hr so that's pretty excellent battery life IMHO.

it is actually a binary file, not sure why they gave it a txt extension. If you removed the "korean" parts you might need to rebuild the file with a hex editor

ICS changes a lot of functions from how they worked in GB. CPU, multi core cpu task control, task management, and power control are all changed.

I would expect the behavior to be different.
[Android Q&A, Help & Troubleshooting] mr72:
I find it unusual for them to behave differently in terms of DHCP lease interpretation (dhcpd), if there is a common bug in both versions. And I find it unusual for Princeton to report the same bug in both versions, indicating it has not been fixed, and yet for me to see different results here. This makes me think maybe what I am seeing is not the same issue as the one reported.

I still think I am seeing an arp issue. I am not clear on how Android populates the arp table. It may be related to a DHCP issue and it may in fact be worked around by changing the DHCP in such a way as to avoid the arp problem.

What I can say with certainty is that the primary effect, why I had no data connectivity after sleep on my phone, was due to an incomplete arp entry for the gateway address. How that incomplete entry got there, I don't know. Whether it is a bug in arp (unlikely), configuration of the phone (much more likely, sysctl settings), or dhcp misbehavior feeding bad data to arp, I can't say.

I would have to see that to believe it. In the past 8-10 Android phones and devices we have here, I have yet to see one that will go 24 hours powered on and being used on one charge.

My Nook Color, which is extremely tweaked for battery life, drained nearly 10% in 8 hours overnight last night and that's in deep sleep with wifi off. Just sitting on the night stand. This is a device that will play high-def movies for 10 hours straight and that I have had the screen on reading ebooks for 17 hours straight before.

On the contrary most Android phones I have seen will last about 2-4 hours with active use (on the phone, playing a game, watching a video, surfing the web.

Before galaxy s I had an iphone 3g, which also lasted over 1 week. however, as I said usage was very minimal, maybe 10 minutes on call and screen on time less than 30 minutes total during the week. And, no magic here as they lasted only 3-4 hours on heavy use and 7-8 hours on ebook reading.

Tablet without cellular radio should last much longer on standby. I also had a NC and it lasted at least 2 weeks on standby with wifi off and can go further. I remembered dalingrin said NC should last a month on deep sleep.
[Android Q&A, Help & Troubleshooting] mr72:
We have two iPhone 3G here, and I suppose it may have been possible at one time to get them to sit on standby for a week. However, we carried chargers for them everywhere. With normal use we couldn't get them to last beyond waking hours.

Yeah maybe mine didn't go into deep sleep last night. I charge it every day. I don't really concern myself with how long they will run while not being used. I have only run it flat when it was actively being used.

FWIW, update:

1. my wifi seems to be FIXED !!!! The answer was to change the DHCP lease time on my wireless router from "forever" to "30 minutes". Might actually work with some other setting like 24 hours, I will experiment.

2. at home working all day on wifi, including some web browsing, emails, and at least one 30+ minute phone call, I have used only 27% of the battery in 10 hours. 2.7%/hour with normal usage is killer IMHO. I doubt on GB my Burst would be over 50% battery by now with the same usage.

Why does Nash effects interfere with Android audio effects? If one is working the other one breaks off there is unmanageable stutter.

So more on the wifi issue...

I changed my wireless router at the house to "1 day" lease time (was 30 minutes), and the problem came back. BTW this is a Belkin router.

I think the problem is that when the phone goes to sleep it doesn't actually keep the wifi connection open all of the time. Maybe for some length of time, but not the whole time... ? guessing really. Then when it wakes it tries to renew the ip address with DHCP even though the lease has not expired, and fails because the DHCP server in the router doesn't respond. It's already got a valid lease. Changing the lease time to 30 minutes increases the odds that the phone will get a new lease whenever it asks, while changing it to 1 day breaks it again because the router doesn't respond to the request.

Looks like the phone is ageing out the arp entry for the router while it is asleep and then when DHCP fails it marks the stale arp as "incomplete" and then won't talk anymore, even though the cached ip address it is applying from the old DHCP lease is still valid, and since there is an incomplete arp to the default gateway (default route) address, the kernel shuts down ip networking, for example pings get "Network Unreachable".

This is definitely different than what my Burst did with GB and also different than what my wife's HOX does (with ICS).

GPS issues? Endomondo's fault, Google Maps not great

I was having trouble getting Google Maps to lock on the GPS (navigation mode) and Endomondo seemed to refuse to acquire GPS.

However, checking with GPS Essentials I found that the GPS quickly acquires satellites so there doesn't seem to be anything wrong with the hardware or software on the Burst.

With Endomondo, it would simply refuse to lock, ever. So I uninstalled it and switched to SportsTracker, which works great.

As for Google Maps / Navigation, it works fine but sometimes it refuses to lock and the app must be restarted, sometimes more than once. It will either acquire lock within a minute or less, or never, and if never then restart the app until it works. This seems to be a bug in the Google Maps app.

Will your router allow you to reserve DHCP? It's where you tell the Router the MAC of your device, and telling the router to always give that MAC a certain IP.

ex:

Set it so that MAC 00-FF-26-6D-F6-A9 is ip 192.168.1.50. So every time a device with mac 00-FF-26-6D-F6-A9 connects it will get 192.168.1.50.
[Android Q&A, Help & Troubleshooting] mr72:
Doesn't matter. The problem is not the router. If I set a DHCP reservation then it will just give that address when requested, rather than give an address from the pool. But the problem is that the phone, while it still has a valid DHCP lease, is nuking its arp entry for the gateway after it is asleep for some amount of time. When the screen comes back on it tries to re-up its DHCP address, which is unnecessary because the DHCP lease is still valid, and for whatever reason it doesn't like the answer from the router and winds up marking the arp entry as "incomplete". If there is no valid arp to the gateway, the phone cannot communicate.

Now, like I said before, if this was a normal Linux device, then I would easily fix this. A minutely cron job to clean up the arp table of "incomplete" entries pointing to the default gateway address and then send a gratuitous arp would do the trick. But on a phone, I just don't know precisely how to accomplish the same workaround.
