Hello all! Please forgive me if this has already been answered (i did search the forums before hand), but is there a way to undervolt our wifi card? i had an older junky tablet where we could do that and it was amazing how much it helped with battery life and the heat it made. Unless this isn't a problem on our tablets, it would be nice to know.
p.s. - in my search on other forums, i saw that some kernels have governors that adjusted the voltage to the wifi card based on overall load. do we have that? i haven't noticed any yet.
I'd be interested too. I'm usually using phone hotspot and it sits right next too me, so I don't need much power to it most times.

I been reading lots about Asus Transformer and it looks like Sleep Of Death happen alots on the Asus HoneyComb.
What about Xoom. anyone experience it ? I cant find it here after doing some searching.
Edit.
What is SOD.
The device fail to wake up after going into sleep. It just freeze after pressing power button.
In some device removing and replacing SD-card fix the issue but it still come back. There is no permanent fix to this unless it is a software issue.
I will put it NO if it happen less than 2 times a week or the frequency did not irritates you enuf.
PS: Not sure why comment below is taking about gay and chicks. I hope they understand what I mean in this thread.
No I'm not into gay porn on my Xoom you sicko!

Not seen this on my UK/US hybrid Wifi Xoom.
Lol...I must be missing the point behind those comments too! No issues here 3g Vz.

Chlorophyll? More like borophyll....right?
I'm very familiar with SOD - it still happens on my Touch Pro 2 occasionally.
I've NEVER experienced it on the Xoom in the month I've owned it with either stock or Tiamat kernels.
(knock on wood) - my Xoom has never frozen even with the screen on.
Force closes are a fact of life, but this Xoom has never crashed requiring hard reset.
no hard crash here. just apps.

Never seen it myself and i use my Xoom all day long. Though my backlight did die on me less then 3 weeks into it's life, thank god for free warranty repairs
Mine didn't wake up from sleep once. I've heard of it happening on the Xoom but only once or twice, not common at all.
I've got a euro xoom 3g. It sod'ed often.
This happens on stock 3.1 and tiamat 3.2
Im looking for a solution to this as it's very annoying.
This happens regardless of what wifi sleep setting is selected. Even with never disconnect it will still fail to wake after the screen turns off.
It never happen to my xoom.

I've installed tiamats 2.1 tachi oc kernel. It appears that the sod issue is now gone.

I've seen plenty of threads where users complain of a SOD problem. Being a GED device does not mean that it is immune from such an issue.
It might not be every device, but apparently its happening often enough.
I've started a thread here with the goal of consolidating all SOD issues, in the hopes of finding a solution.

Why do I feel like its an app/software causing this rather than issue with the xoom itself? Did you wipe properly? Flashing over roms can cause things like this...
Hello!
My nexus s i getting very warm sometimes, im on kang milestone (stock kernel) is this normal?
Sent from my Nexus S using xda premium
yes, we all get hot and battery drops faster when this happens.
i think its the cpu governor and clockspeed.
if you put alot of apps on its prossess then it wil work faster, faster = frition. friction=hot. hot= battery drain at a faster rate. dead batt= xda question theads more threads= cramped order. cramped order= more cliick and seeing more ads. all us seeing more ads= more money for xda. xda=thrives off newbies
welcome. we are xda.
But is that normal? Can you recommend any rom that doesn't do that?

It's likely to heat up your phone when playing 3D games, using GPS an the like. Depends on what you are doing with the phone. Also, if you use OC it might get hotter than usual. If you think it's heating beyond any limits, try going back to stock for a couple of days, then if it does the same thing, consider hardware issues.
Is the screen getting warm even with minimal use? I had similar issues with cm7 once when I forgot to do my wipes.
Same with mine mate, few minutes on 3g with full brightness and u can start frying eggs on display screen.
I've found out that it's not happening when my brightness is adjusted at about 50%.
Just wondering how many of u, have set up their phones in auto-brightness mode, cuz i don't see to many post on this forum, regarding overheating issue with nexus s ...

I keep mine in auto-brightness, haven't had this problem.
That's strange, I'm running AOSP+ and Eugene's kernel, not overlocked or anything.
I found with some of these ROM using auto brightness just made it dim and go bright crazy. Either way. I found as bad as it sounds a fresh install the best thing. Titanium backup, sms restore, and then wipe everything clean. Solved all the hassles
Mine has gotten warm with heavy use since I got the phone.
If your running voodoo and have your gamma sliders boosted to hell and back, this also will make the phone run *quite* warm.
Maybe just new to the tablet but.. Wi-Fi sucks battery like no tomorrow. Maybe it's the battery monitor built in that doesn't read it right but when Wi-Fi is using 70-80% of the battery (by far bearing screen). Just curious if anyone else has the same thing. Get great battery time with it as long as I'm not paying with it, and in standby it uses next to nothing. Just when on the Wi-Fi goes into overdrive.

My understanding is that the built-in battery monitor just isn't accurate....

Ok cool. I figured that was the case just as it is with my phone. Just had an older phone that was really accurate so just use to that.

I could use some help here...I have been on Turge's Viper ROM for the last few weeks and getting fantastic battery life (increasingly better with each time I charge the battery). Well, today I took my phone off the charger and it has now dropped from fully charged to 80% in just an hour and 1/2, with very light to no usage, and mainly on Wi-Fi. The only thing that I can think of that is different is that I just got a new router. Is it possible that a new router could somehow be impacting battery life? I have not changed any of my wi-fi settings or other settings, really just been "business as usual" with this sudden battery drain.
If anyone has any ideas or suggestions for what could be causing this and how to fix it, please comment!

I'm on stock jelly bean and only getting just under 3 hours of screen on time. This is horrible and besides screen drain I'm getting most of the other drain from wifi. Anyone know whats going on? Any help would be greatly appreciated
Edit. After Google I see it's a known issue

Try killing off Google maps if it's running.
Shut blue tooth and GPS off if not using them.
These couple of things might help.
One thing to know and remember: The percentage mentioned is not how much of your battery it uses, it's how much of the current battery usage belongs to the app/component.
Running any live wallpapers? Auto brightness? Which power-setting mode? Location services?
i am having the exact same issue, balanced mode, 35% brightness, no gps, bluetooth on etc and having only 3 hours on screen? Unfair because this tablet is perfect other then that
I would assume it's normal, it might use more than it's supposed to but wifi and screen will usually be the worst sinners, depending on what use of course.

Thanks bud. It's definitely not normal. After doing research I come to find out its a problem with Asus code. Wifi should never be anywhere close to being reported by the battery use stats. Hopefully we will see a fix sooner or later

If I am not mistaken an update came out either yesterday or today that had the WiFi issues noted in the changelog. Check the ASUS website.
