Battery drain on 3.2 Roms - Acer Iconia A500

Hi all,
I've tried just about all the 3.2 roms and all of them seem to have the same issue where the rest mode is interrupted often, screen turns on by itself.
Is it one of my apps that could be causing this, or does everyone see this type of issue?
Anyone have an idea how i can track down the cause, in the case of an app being the problem ?
I could try turning off Wifi at night to see if the drain continues , and see if its an app that is connecting regularly....

Some apps like TrafficInfo can help you monitoring which apps/processes use your bandwith. It can give you some clues if a specific app is draining your battery.

Same problem for me..
I have tested all 3.2 Acer based ROM, only solution for me is Airplane Mode..

I have also had this problem with my Iconia. After I flashed the Kernel below, I have had no problems with the screen turning on by itself. I have only used it a few days, but untill now is good.
I don't know if this kernel work with OC/UV since I don't use it.
I found the kernel in the [KERNEL] Stock/HV/Taboonay thread.

I've been having the same issues after trying Taboonay-2.2, thor and someone elses ROM. Have tried airplane mode, disable wifi when screen off etc.
I'm going to flash back to a 3.1 ROM and see if there is a difference or if I'm imagining things.

Same here too!
After I switched to diff ROM, my Tablet is not shutting down anymore.

Funny, but I haven't had that problem since 3.01, but then again I have my tab set to disconnect wifi when screen goes off. Not sure if it's the ROM, or my settings.

Had mine set to that for the last 3 days or so and at times it's perfect for hours then other times it's on/off every few minutes so I don't think it's a setting problem.

Turn airplane mode on (this will disconnect your wifi), then reconnect wifi.
Set wifi disconnect policy to "when screen turns off".
Using the settings listed above, I've never had my tab wake up prematurely, never frozen from wake up, etc.

Crappy GPS *With screen shots*

My GPS has been rather worthless, it used to be perfect but even before I rooted it went south. Now I"m on CM6.1 Stable and it's pretty bad. Every thread I see about the issue just says get GPS Status from the market and clear the GPS cache and download assist data. I've had Status since my old phone, and it's not helping.
When looking in status, it rarely locks on. It picks up several satellites but fails to ever lock on. Like this:

The accuracy is HORRBILE, won't narrow down from this:
I was in that bubble at the time, but the very edge of it.
And While moving *At 70mph in this pic, don't worry I was just riding...*, the curser is always crooked like this:
And the only time it would move down the road is when I'd wait till outside of that bubble, and click the my location button again, then it would be another still shot.
It appears that setCPU has something to do with it. Anyone else getting this? Even leaving it at stock speeds gps acts up. I removed the widget, killed Set on Boot, rebooted and now have gps back.

I am running CM 6.1 and am using SetCpu to overclock the processor and have had no problems with GPS. The initial lock took a minute or so, but it was easily able to determine my exact location. I used it yesterday afternoon to navigate to a christmas party and it was able to find my location quickly and kept up with me as I was driving in my car.
Hrm, maybe different kernel? I was on the 1.8ghz one but did a full wipe and put cyanogen with the kernel it comes with, verifying that it didn't let me go all the way back up to 1.8, that fixed lots of my issues but gps still flakey.
I work in photography which takes me all over the city, so I need my gps

Send it back, get a new one.
works perfectly fine without the SetCPU though, so it's not hardware.
My gps always screws up at first too. It'll put me across the neighborhood and say "accurate up to 3200 meters" or something stupid. However, if you tap your little arrow, it should fix itself. That's what I do with mine. Works every time.
I can try that, I'll be riding around today so I'll play with it lol. I've been tapping on the My Location Button in the top right, think that does the same thing?

You can also try using CPU Tuner in place of SetCPU and see if it works that way.
alright, I'll try that. I'm quite android modded out for the day and got homework, but I'll attempt that tomorrow
GPS works perfectly for me on the G2 using Virtuous ROM. Way better than it did on my old Vibrant
I have the same problem!! I accidently hit power save setting, and came back to conservative.
I have even unistalled setCPU, but GPS still not working! help!!

[Q]WiFi automatically turns on?

I need some help. My wifi just keeps randomly turning on throughout the day and its really annoying. I checked my settings and im pretty sure there is nothing that would do that but I could be wrong. Anyone had the same issue? Anyone know how to fix it?

I'm seeing this as well with a Bell Galaxy S4 (SGH-I337M). I have no idea what's causing it.
Ok. I think I *may* have figured it out.

Im using qualcomm battery guru and I went to the app to check my battery savings and I came across the manage wifi option. It basically says it will turn your wifi on and off based on your previous usage. Ill report back in a little wilhile to see if that fixed my issue.

I had this happen on mine and I think it was something to do with AT&T Smart Wifi. I don't remember though.

I don't use this app so I'm not sure if that's necessarily the issue, unless something similar is built into the Qualcomm chipset itself. It does seem to always enable itself at certain points of the day, I'm going to keep an eye out for a correlation.
So ever since disabling WiFi yesterday it hadn't turned on, and I thought it might have fixed itself. Today, I went the whole morning without WiFi and without touching the phone and when I looked at it later on it was enabled. I checked the battery stats and noticed that WiFi seemed to automatically enable itself the moment I woke up the screen to check a message a little while earlier.
I've also noticed that when this happens, it won't actually connect to my WiFi network when it's in range like it's not actually scanning for any networks. It also won't let me know of any open access points. If I disable and enable WiFI again, it connects like it should, or if I go into Settings -> Wireless, it'll scan for networks and connect fine as well.
It seems like this is a software bug that Samsung needs to address.

[HOW-TO] Stop wifi from dropping

As many may have experienced, when connected to wifi after a few hours, WiFi stays on but disconnects from the access point for no reason. It seems to happen on the s6,s s5 and s4 on lollipop. Was I'm Howard forums and someone with an s4 posted something that may work.. Touchwiz has a wifi power safe option turned on. His will show how to turn it off.
Dial *#0011#
Then when the information screen shows up, hit "more" up top. Then hit wifi.
When the new screen comes up, just hit wifi powersave off to turn off the powersave feature. Haven't test for long. Let me know in the comments if it helps
Does nothing for me I'm afraid. Is this any different to the wifi setting "keep wifi on during sleep"?
Does also nothing for me...says wrong.. Mmh
Are you guys using the stock dialer?
I remember the code wasn't working with 3rd party dialer I was using before.

That is switch for the power save mode. It will disconnect wifi for a few seconds.
No noticable change for me, no bandwith or signal strenght increase on 5GHz
I see I'll try it the next few days and report back ☺

Haven't had the issue since. I'm not sure if it's a firmware thing but it should not turn off wifi. This is how is supposed to look
This setting destroyed my standby battery life.

S6 Disconnect Problem
I had the same issue and solved it by changing my routers security from WPA2/Mixed Mode to WPA2 Personal. Since this change, it works fine on both 2.4 GHz and 5 GHz. Tried EVERYTHING else first
this is an extremely annoying bug....data usage has increased significantly because staying on wifi is such a pain, rather just use mobile data. i've heard about the security change, but that's something I can do at home, nothing I can do at work unless I somehow convince corporate IT to change their wireless settings? haha, fat chance.
i just want to know did the change the OP suggested actually work? No one has reported that it actually works other than that it killed their standby time. anyone?
Worked for me, fido galaxy s6 edge thanks

Mobile Radio active bug in Lollipop

I'm getting this bug in every Lollipop Phone I own. And sadly this bug seems to be present in the M Developer preview too.
Usually my day starts with wifi but as soon as I leave the wifi connection and start using 3G the battery starts to drain.
It has gotten so annoying that I switched back to KitKat and my phones are awesome again.
Present for me on Z3 and S4

I noticed this today. Was using WiFi screen was at about 36% use and Android OS at about 6%. Switched to Mobile data, And before 30 minutes, screen was at 28% and Android OS was 30%+
Crazy really! Don't know if a reboot would fix. Back on WiFi tho and it seems normal again.
The above comment was made by me, my friend logged into his xda on my phone and i didn't know, when i knew it was too late.
Basically every app that uses mobile radio keeps the connection active and drains the battery fast.
As seen in the battery tab with "mobile radio active" for hours.
At first I switched to lollipop I thought its just an "feature" but its the bad bug.
Especially for people who doesn't charge their phone for days because of light usage

I take it you are on CM now?
The Z3 is now .77 stock KitKat, the s4 is CM11 M11

so, overall, the power consumption in KK is way better than in L? [assuming similar usage]
cause i bought this phone already on L...
On WiFi it's as good as Kitkat, the problem starts when you have mobile data enabled, from what I hear the issue carried on into the test builds of Android M.
Phonearena even did an article on the issue, and it has the 3rd or 4th most votes on Google 's bug tracker yet it's still labeled as small priority... I hope Sony fixes it by itself somehow.

Freezing cause by unlocking bootloader stops

Freezing cause by unlocking bootloader stops when you deactivate to cores using kernel adiutor however your camera wont work (based on my phone) but it will if your turn on 4 cores.. Im still not sure im monitoring it if it still freezes. Current record is a day and counting without freeze in RR rom.
Note: I just saw this on some of my Fb group i just forgot who posted it because i cannot see it anymore. So the credit is for him im just sharing and might help those who have the same problem as me.:good:
basicly, you're trying to avoid cpu overload right? waiting for your result after 2 or 3 days.

Or you can under lock your phone to 800mhz and use it for over 12 hours I have tested this method and on average got 14 hours system up time
until now no freeze but i forgot to charge my phone and it gets empty and damn my count of hours gets reset..
