Wifi speed while screen off - Samsung Galaxy Nexus

So I was streaming music from MOG and all was working well until my screen went off (idle). Music started to pause/buffer and kept doing so every 10 seconds. When I turn the screen back on and stare at it, it won't do it at all and I can see it load full on the seek bar. Only happens when screen goes off and phone goes idle. I'm guessing its something with the CPU throttling maybe? Is there any way I can fix this? I'm connected on WiFi 5G and I have "keep WiFi on during sleep - Always".

This seems to be a pretty common issue (I have it myself, when connecting via WiFi with adb I need to keep my display on) and I've seen two issues on file here and here. I've yet to see a fix for it yet though

Aww crap. Well that sucks. Does it happen on custom roms/kernels?

I'm running CM9 nightly with leankernel now. Although it's happened since I've gotten the phone, and I've ran probably half a dozen different ROMs and 3 different kernels, including stock. I vaguely remember reading some posts where people either said there was a fix or they were working on it, though I'm honestly not real sure.

K thanks for the info bro.

I am also facing the same issue. Yesterday, I was downloading ARHD 3.0 directly on phone through wi-fi. Surprisingly the progress was 1% completion per minute in screen-off mode. But the moment, I would turn on the screen, the rate became 3-4 times faster. i.e. 3-4% completion per minute.
Deviating from topic, I have seen similar behaviour quite some time back in iPad1.

Yeah, I'm on Liquid 1.25 (4.0.4 based ROM) and it still does it. If I run a speed test and turn the screen off, let it finish and check it; it will never go much over 5 Mbit/s. When I run the test with the screen on, I will get 10-20 Mbit/s. This was of course testing on my home WiFi network.
This is pretty annoying because I download anime torrents every week and it's enough of a battery killer already just to download the thing, but now I have to leave the screen on in order for it to even finish in a reasonable amount of time. I've also tried setting the minimum clock speed to 1200 MHz in SetCPU just to see if it was a CPU throttling/bottleneck issue when the screen turns off. But it made no difference . This can't be a hard fix for Google/Devs.

At least with popcorn and franco kernels you can do
echo 1 > /sys/module/bcmdhd/parameters/wifi_pm
to put wifi on high performance mode with screen off. They say this can enable high throughput.

Yes, I am using ARHD 3.0 which is based on 4.0.4
There seem to be definite improvements and it was worth the effort to update.

As far as I know, wifi goes into a low power state with screen off to conserve power/battery life.

My command put it in normal power mode, but kernel must support it

oooo, so only on WiFi does this occur? On 4g it doesn't?

This also happen to me.. Happened in 4.0.1 4.0.2 4.0.4 so far I managed to bypass the issue with wifi keep alive its a free app from play store.. You could try and comment if that works for you

Threre is no need for any custom kernel module. Im on Stock ICS 4.04 and found an easy workaround. Actually this issue is not an android bug, but an issue of streaming apps that aren't proberly coded for honeycomb and ICS.

[Q] Questions about CyanogenMod, and general battery life

Hey everyone, last weekend I unrooted and wiped my phone, went back to factory settings, rerooted and installed CM6.1 RC2. I've been enjoying it so far (because I hate Sense UI) but I've got a couple of questions that need answered. Hopefully you all can help me.
CM6
1. Is there a setting to turn off always-on mobile data? I cannot find it.
2. For some odd reason, I cannot turn on bluetooth. I've not had a problem with turning on bluetooth with any other rom. In fact, I remember testing bluetooth the night I installed CM6. Is this an issue with the phone or the rom?
3. No matter how much I turn off Auto-Sync, it turns back on. What is doing this?
Battery Life
1. On average, I get around 10-14 hours battery life a day, maybe a little more if I barely use my phone all day. I've heard a lot of people say that an ideal battery drain with the screen off should be 1-2%/hour, but mine will drain from 6% to even 10% in 40-50 minutes (EDIT: Currently 75% battery left, unplugged for 2hrs 30min, done nothing but use the browser for 5 minutes, download something, and install it)! I use systempanel and spareparts to monitor which apps could possibly be doing this, but none look like they're eating up too much of the battery. I check Facebook 4-5 times a day, use the browser, and check Gmail. I don't use Google Talk. My screen brightness is around 30-40% and I have underclocked when the screen is off with setcpu. What is draining my battery so fast? It's a shame that there are so many cool things to do with this phone but I can't do them in fear of my battery dying before the end of the day
Sorry, that last question was long, but I did not want 2 separate posts. Thanks guys, I hope you can help!

1. no. you could however turn data roaming off or use a program to accomplish this such as "tasker"
2. what do you mean you cant turn it on? what does it do when you enable it? use the widget in your notification drop down.
3. turn off background data as well and that should fix your problem.
and as for you other question. 10-14hrs is perfectly normal for battery life on cm6.1. and fyi: its RC1. there is no RC2 for 6.1 as of yet

Ah thanks for correcting my mistake, and answering my questions. My battery life isn't terrible per se, but I guess I was asking more on how I could make it better (and if I had a rogue app/other battery eater), especially because I see people claiming anywhere from 20-40 hours with a few tweaks.
And regarding the bluetooth issue, it just won't turn on. The option grays out for a few seconds like it usually does when it's initializing, and then it doesn't turn on. The notification widget method does not work either.
Also, there's no other way to turn off auto-sync? I just think it would be a hassle having to turn background data back on everytime I want to use the market. I use JuiceDefender, too, could there possibly be a conflict between the app and my phone's settings?
Man i'm with you here, I use CM6.1 too and love it but the first 30 minutes i unplug the phone from charging i'm already at like 90% battery =/

Do you feel it really increases battery time?
I am currently trying out Juice Defender free on the standard preset for my unmodded Galaxy Nexus. Unfortunately I am not thinking that I am going to continue with it.
So far it has crashed my phone to reboot (first time that has happened) and when not using my 4g it turns it off but it takes forever for it to come back on once I want to use the phone and it gets pretty frustrating having a useless phone for about 5-8 minutes everytime I pick it up.
I hope you have better luck than I am having.

Strange. It's never done any of that on mine. I'm on HSPDA+ though.
As for whether if makes a difference I'd definitely have to say a big yes. But it all depends on how you use your phone.
Ultimate working nicely here. Syncs every 15 min like it should. Screen is eating 60-70% so it makes only a small difference.
Sent from my Galaxy Nexus using xda premium
I bought ultimate, and found it to be a bit of a hog. I then turned off all the extra stuff and went back to the basic setting - the same as the free version, and noticed very little difference.
I think it might help you if you're one of those people who accidentally leaves radios on, or don't have high signal most places you go. For me a UV kernel made the only real difference.
It works well but not saving as much battery as it did on Gingerbread. Default Android idle-time battery management seems to have got much better.

This. I see a nice increase in battery life while I'm not using it, but if I have it on a lot (which I usually do) the battery gets drained pretty quickly.
I keep my phone on CDMA mode most of the time, unless I need to download something or want to watch a movie, then I switch to CDMA/LTE. I'm still not sure how much it helps though, as I've only had the phone for a little over a week.
For me, JD Ultimate works wonders. Especially when I'm at work and not playing with the phone too often and having only 2 signal bars, JD enables radio every 30 mins to allow apps to sync. It also manages my brightness automatically, which results in screen usually taking less than 50% of battery.
In general it helps me a lot, like it did on SGS2. My night schedule uses airplane mode and I only loose 2-3% over night.
I would have to remember about too many things if not using JD, so for me well worth it.

It does, i never used beta and JD controls my brightness. Remember there is a bug related to manual apk install where you cant tap install. I still use JD for brightness, just disable it in quick menu when manually installing apps then reenabling right away.

When JD is managining brightness, if the phone is asleep, when waking it up with the power button the screen comes full brightness and then settles to a lower level, which is quite annoying. Do you see this happening too?

Beacuse, believe it or not, it provides functions that some people find useful. Same goes for LightFlow, if you like the white-only color led notification of pure android, then you don't need this app either. If you prefer more colors/choices, then you do.

I purchased JD Ultimate yesterday so I can't really comment on how well it is improving my battery life. I will say that I am having issues going back to LTE when the screen is unlocked (Using the network mode setting). The phone keeps going to WCDMA instead of LTE. However, I noticed that since I have been using JD Beta 3.8.8, version 3.8.9 has come out and has addressed a few of my issues. The configure apps now works without crashing JD. I still don't know if the LTE is functioning incorrectly as I haven't had time away from my computer (I have no Wi-Fi at my hotel and must tether).
Is anyone else experiencing issues with the phone going to WCDMA mode after the phone wakes up? Also, what version of JD are you using?

How can I track down my battery drain?

Leaving my OP in place, but I have rewritten the description with much more detail and pics here
http://forum.xda-developers.com/showthread.php?p=25401417#post25401417
I suggest skipping to there.
I am looking for general tips here. E.g., not asking you to diagnose my specific problem so much as give me ideas of what else to check or try.
Lately I have had unexplained (to me) battery drain. Yesterday I lost about 25 percent in an hour while the phone idled. It is not a constant thing, though. I can go an hour and loose 1 percent then loose massive amounts in the next hour.
Now, i have searched, but I have not found anything that applies to me.
I have:
Tried a different radio
Tried a different kernel
Reflashed my rom
Phone is entering deep sleep according to cpu spy
There are no unusual or excessive wake locks according to better battery stats
No apps are using a lot of battery.
I am in a low signal area at work, but putting the phone in airplane mode and dissabling background syn does not stop the drain.
Ideas?
might be your phone is loosing signal? i would check the battery stats in the settings menu to see if you have a poor mobile signal.

I do, and on reflection it is a possible culprit since I added it recently.
Didn't occur to me since it was producing no wakelocks and the battery stats did not showing as using much battery.
I shall turn it off for a bit and see if that helps. (unless there is some other way to test if it is the problem first.) I am off to the search button!

This is from yesterday when i set it down unused for about 90 minutes. The amount of wakes seems liek a lot, but it is similar to what i see when i have far far less drain, so I don't think that is the problem. I didn't get the app list screen, but out should screen as the only major drain with about 2 minutes.
I know it is shows poor signal strength, so immediately after that shot I put it in airplane mode, turned of sync, and rebooted. The battery continued to drain and graph had the exact same slope under those conditions. (Forget to get a pic though.)
Sent from my jitterbug using tapatalk.
System panel paid version with monitoring enabled is the best for tracking apps using CPU.
OK, still working on this.
To recap:
When the screen is off, and no apps are running I sometimes get inexplicable battery drain. This is occurring under conditions when I should be experiencing little or no drain at all. I say this becuase:
The screen is of and no bakground apps are running
the phone is NOT awake and IS entering deep sleep (as confirmed by cpuspy)
there are no unusual kernel or partial wake locks
there are no apps listed as using unexpected ammounts of battery
This is not a universal problem. The phone *often* behaves as expected. I can leave the phone off for an hour and see a 1% or 2% drain, and I am happy with that. However, sometimes, randomly, it goes nuts on my.
This graph from a few weeks ago shows what I mean. Look in the green box. The phone is sleeping, and the screen is off. The graph starts as a flatline, then, all of a sudden, it begins to drop precipitously.
Here is a graph that shows the battery dropping at the same rate whether the phone is awake or sleeping:
I have gone the following to try and narrow the problem down:
Done a completely fresh install of my Rom including a system wipe.
Tried two kernels (the aokp default and several relases of Franco's
Tried a different radio
Activated and installed a new sim card
I have come to suspect that the problem is network related. When the problem starts, sometimes going into airplane mode and back and/or toggling 2g only temporarily fixes the problem.
I suspect that something is happening with my connection to T-Mobile that keeps the network running and draining power. This is pure speculation, but it is all I can think of.
I installed juice defender (which I had not been previously running) and noticed the that, sometimes, it didn't turn of data when it should have. I also noticed the following two things happen:
I do not believe it is a rom problem, since if so, someone else would be reporting this. It might be an app problem, but if so the app is draining battery without a wake lock and while the phone is in deep sleep.
It is not exchange (as was suggested in this thread) since it continues when I ev my exchange account.
I have no idea what else to do or try.
Since it happens at random and takes a while to identify, uninstalling one app at a time to test for that could easily take months to narrow down a misbehaving app.
I know it is not a hardware issue since last month I got this:
That was with AOKP and Franco (earlier versions obviously)
I have google searched till my fingers bleed.
I am a long way form being an expert, and I suspect I may have overlooked something obvious.
Please, any thoughts??
Damn you definitely have a major issue and I don't know what it could be. But when my phone sleeps itstays dead flat with no awake bars, and drops 1% every 3 hours.
1. Calibrate battery
2. If you really wanna find the problem, install the rom with no mods or apps and run it and see if it still happens. Then add back each mod/app one at a time

While I appreciate your effort, this is remarkable unhelpful for the following reasons:
1. "calibrating" the battery is a myth and doesn't actually do something. Even if it did, it would not explain the symptoms I have described. I have been around xda long enough to know it is the knee-jerk reaction to any battery question, but it is not relevant here.
2. Since the problem occurs at random, and sometimes takes hours to show up, (For instance, last night I charged to full and tried to catch it happening. For 4 hours nothing happened, it behaved perfectly. Then I went to bed and it immediately started to fall and was dead by morning) and since I have over 100 apps, your suggestion could easily take *over a year* to follow. Believe me, I have thought about it, but I started this thread hoping for ideas that would allow me to avoid it.
Here is that chart for last night.
I had about 1 hour and 30 minutes screen on time with 65% left when I went to bed. When I woke up, phone was dead.

Mine often does that. But sometimes it doesn't. It is the fact that it happens seemingly at random that makes it so annoying and hard to track down.
I would replace the battery
One thing you haven't rulled out is that the battery itself is bad.
Have a friend you could swap with for a day, or at least long enough to see if the problem follows? If your battery drops on their phone that is also a good indication.

The thought has occurred to me, but unfortunately, no, I don't have a friend I can swap with. And really, since I have had the phone less than 3 months, the battery *shouldn't* be bad, but yeah, defective products happen.
If I cannot find any other cause I will likely order a new battery and see if that fixes it.

1. yes battery calibration does make a difference.
2. ok, so an app can't run a process at random? especially when you have "over 100 apps"? Run the rom stock and see if it still happens, or even run the stock rom/kernel. if you don't want to try this then why are you asking for suggestions? christ

We'll of course it can. That is kinda my point. If I go one app at a time waiting for it to "run a process at random" I am talking literally MONTHS of testing. I would have to wait many hours, if not days after installing or uninstalling an app to be sure whether or not it made a difference, then move on the the next. This is simply not an option. I started this thread in hopes that a realistic and doable solution might exist that I was unaware of.

I am asking because there may be a solution that I am unaware of that doesn't require me to put my entire life on hold for months. It is possible that there is no such solution, but I asked in case there was one.
Sorry to have put you out so much.
You mentioned you recently installed exchange sync. Did turning off sync remedy this or have you not tried disabling all sync features?
One other thing to check is the background data usage of your apps. You'd find this under 'data usage' and make sure you enable the wifi tab so you can see data usage on wifi.

when i did a complete quote and re flash i did not setup the exchange account, but the issue continued.

My battery also drains at a rate similar to yours however I'm on the CDMA version. Hopefully you can figure out what's going on with yours.

Battery usage much higher on 3G than WiFi

Hi,
Have you guys noticed our phones tend to drain battery much much faster on 3G than WiFi? I have yet to measure the drains accurately yet but I think the difference is huge. I can drain the entire battery in 2-3 hours with data on and active data transfer.
For example, stream some music on TuneIn on wifi and then on data (3G/H+). On data, the phone gets really hot and sometimes even with an AC charger plugged in the battery can barely hold charge (with screen also on). On Wi-Fi the phone stays cool and battery consumption seems to be much less.
I feel like it's ok for data to use a bit more power but I feel like this much of a difference is not normal. I have WCDMA preferred in mobile options, and it is displaying H+ in the status bar. I am assuming it isn't using LTE or looking for an LTE signal... How can I make sure of this? Is the LTE a different radio/chip that can be turned off separately?
I'm on CM10.1.2 with Wind Kernel 2.5.
what do u think requires more power receiving a signal from 30 meters away or a cell phone tower
having said that if your rom is pulling more than usual from data connection you can try switching to cdma only mode, also i think the stronger signal you are getting the less power it uses but im not sure on that, i think if u are in a basement or something it will pull more power.
or try switching roms
it is not the "phone" unless your phone is defective
try a differant rom if that doesn't work try a differant baseband if that doesn't work phone is probly defective or partially defective
first thing is try a stock based rom
btw i think the only time wifi will take more power than 3g/4g data is if you are sending huge amounts of data over it or have it on constantly scanning for networks, or have a rom that makes wifi stay on fullspeed while sleeping

I'm just trying to gauge if people are seeing the same thing as I am. I haven't switched basebands in a while. Any further informative comments are welcome.

No I haven't, I kind of just assumed it had to be normal. The phone gets hot just like when you're talking on the phone for a while so I thought it made sense.
I have some preliminary numbers (didn't let the test run long). If you want to replicate this, get Android System Tuner, and set up a widget to show "Average mA since last measure". Turn brightness to minimum and set the display to not turn off, start streaming TuneIn radio, unplug the phone (to reset "last measure), and let the battery go down at least 5%.
-360mA - wifi on streaming music, screen low brightness (20%/hour)
-760mA - 3g on streaming music, screen low brightness (note that's 41.5%/hour!)
-400mA - 3g on streaming music, screen off (22%/hour)
These preliminary numbers would suggest WiFi uses almost nothing, since the screen seems to be about 360mA, whereas the difference between WiFi and data is 400mA!

if it was me before i bothered with any of this i would have redownloaded and wipe/reflash rom, i just had my phone streaming music on 3g and it didn't even get warm

Could you please check what baseband you're running (I'm on V20e)? Does flashing CM10.1.2 change the baseband?

ive never had to flash my own baseband everywhere i read people say only do it if you have issues and ive never had issues, the rom/kernel i'm using is in my sig
there is a baseband archive in the developement section if it comes down to trying differant basebands although i'm not the person to talk to about that as i've never done it, i'm sure if you end up doing that asking on that thread would be your best bet as you will probably get responses from people who have done it before.
here i'll even link it:
basebands
this is a last resort and be very careful when flashing these

Yeah I would have to second that, those mA are way too high. I am @ < 100 mA on H+ streaming off slacker now that is with stock, but when I was on cm10.1 I would have to say it was about the same. The ONLY time my phone gets warm is on GPS & charging, and my phone is over clocked to 1728 all the time.

Thanks. I've changed basebands before with packages from that thread. That's why I'm asking if flashing CM will override those.

i'm honestly not sure if rom flashing changes baseband my gut instinct would be sometimes yes sometimes no but i'm honestly not sure, i dont even look at baseband unless i'm having problems with my radio signal and i never have.
ur problem is probly caused by you changing yours.
my baseband is: apq8060/mdm9200
have u tried what i suggested and flash a stock based rom to see if that fixes the error, then if you want to go back to cm10.1 u should be able to as long as you dont mess with basebands again
it's possible this doesn't fix the error if the stock rom doesn't flash a baseband, i'm honestly not sure if it will but it might
be careful that you don't flash one that reflashes a locked bootloader, most of the stock based roms on the developement forums have it disabled

Thanks, that's what I'll be trying today. I was on V20e (newest Bell one from that thread). Yesterday I tried V20c, V10j. All are pretty much the same in terms of power usage as I tested them yesterday. I will try a stock-ish ICS today and test there.
BTW, I tried the streaming test on a Nexus 4.
-550mA screen on lowest brightness streaming 3G (compared to -760mA for mine)
-360mA screen off streaming 3G (compared to -500mA for mine)
So the differences aren't THAT drastic, but still.
So here's some updates:
I flashed V20f mod V2 by HoNo (a stripped down and CWM flashable V20f stock image from Bell).
At first, I thought everything was fixed, as I was seeing battery use at about 500mA with screen on lowest brightness, streaming over 3G. However, I think this was due to the battery being low and the battery % dropping slower when it's under 15% (Android Tuner free uses battery % and battery capacity to estimate current draw).
I charged the phone overnight, then I flashed my CWM backup of CM10.1.2. The good thing is it kept the V20f baseband (and firmware) from flashing the V20f rom. That confirms that CM10.1.2 and CWM backups don't save/flash baseband.img and firmware.img. However, again, I was seeing 700+mA draw. There might be better idle usage with the new baseband, but it might be placebo.
I went back to a CWM restore of the V20f rom and tested again on the ICS-based stock-ish rom. Battery consumption is still high (700+mA streaming on data and screen on lowest brightness).
Could one of you guys please try running the same test I am? Here's how:
0) Ensure your battery is in the range of 50-90%
1) Download Android Tuner Free (AT)
2) Download TuneIn
3) Add a AT widget (1x1 text option) to a homescreen
4) Tap the widget, go to settings, widgets, widget content, central value, choose "avg mA since last measure"
5) Go back to AT settings, battery, calibration, battery capacity, enter 1830.
6) Start to stream music from a radiostation on TuneIn
7) Set screen timeout to 5 or 10min
8) Set brightness to minimum
9) Plug phone in
10) Unplug phone (this resets the "avg mA since last measure")
11) Watch the central value as your battery drops for 10-20minutes. Since drain is an estimate based on % dropping it will jump around a bit but level off the more time you let it run.
12) Don't do other stuff on the phone so you aren't using the CPU more than for this test

[Q] HTC One X MaximusHD 21.1-Some apps have problems with connecting when using WiFi

So today I've installed latest MaximusHD rom for HTC One X, and everything is super fine, except for one thing - when I'm trying to connect to my Skydrive (using official app) while on Wi-Fi I just can't do it. After awhile it just says that I should check if I have a connection. The problem does not occur when I switch to Data Transmission. Other apps usually are able to connect but it seems slower than when using Data Transmision.
I have installed the WiFi update, and when using Google Play, or browsing the internet it seems to work just fine... I also switched from Superuser to SuperSU, but the problem occured before that so I don't think it had anything to do with that (noob question - which should I use? Superuser was there by default, but is ist actually better, or there is no big difference?)
Have you tried uninstalling and then reinstalling the app?

I tried, it's still very slow.
Other odd thing is that when I turn on Data Transmission it's always showing the "H" symbol, even in the places where it previously showed "3G" or "3.5G", now it never switches. What does it mean? The speed seems fine though.
This happened to me too. And it's happening to YouTube and google play.
Could it be because I didn't do the OTA update?
In that case i have a little question: if I update the OTA do I/will it wipe all data?

Well I did the OTA update almost right away (after intalling few apps), and I saw the problem after that, so I don't think it has anything to do with that although it's suppose to fix WiFi. Oh and it didn't wipe my data.
EDIT:
Well I can't post in MaximusHD thread yet so I'll ask here, does everyone using this rom experience such a tremendous drop in battery life when using Data Transmission? On WiFi it's normal, but when using cellular it drains 5-10% in 10 minutes... That seems absurd.
bump. Seriously? Anyone knows if this problem with power drain when using cellular data transmission is also present in other clean Sense 5 Roms? Or is there a way to fix that, or maybe there is an update underway?
I just switched ROMs but was getting a full days use out of a charge. WiFi at work and home all day. So I never really used hspda.

Yes! It does this for me too. It seems to drain at something like 1% per minute for me when I have mobile data on. Wifi also drains it quickly, but not as fast. I posted about this in the Maximus thread (some other issues too) but nobody has replied. Good to know it's not just me.

Yep, hopefully there is going to be some kind of fix, I really wouldn't like to go through the whole configuration, app instalation, etc. process again.
Ok, so another thing is - some icons in one of the folders on my home screen disapear. It's always in the same folder, and only in this one, others seem to be unaffected.

Issues I'm having:
1. Crazy battery drain when I enable wifi, but particularly bad when I enable mobile data. I have a Tasker profile where if I enable wifi and connect to my home network, autosync and GPS are enabled for 2 minutes then disable themselves. Last night my phone was on 61%, I enabled wifi, and immediately it dropped to 56%.
2. When I go to bed at night I turn my phone off. If I put it on charge at night it gets to a certain point and the phone switches itself on! One night last week it switched itself on at about 89%, so I switched it off again, and about ten minutes later it switched itself on again!
3. I use Google Calendar, not the HTC one. I seem to be unable to disable the HTC calendar - the only option is to "freeze" it in my backup app.
Aside from these things, I really like the rom, but these three issues are making me wonder if I should try something like ARHD and see if the same things are present there.

Well I don't know how it is with the phone turning itself on, because I'm not turning it off to begin with.
The thing with calendar - it seems to me it was also like that when using official Sense 4+, so I don't know if it's fixable.
I think I'm going to switch to ViperX Sense 5 Rom, people seem to say good things about battery life in this one.

Yes, I know some people think the idea of switching a phone off is somehow weird, but I turn mine off at night. As an experiment I just switched my phone off here in work, plugged it in to charge it (it was on about 93% - charged overnight and it has lost 7% since I switched it on when I got up for work at 5.30) and lo and behold it powered itself on when it reached 100%. I don't want this to happen.
The calendar on Sense 4 could be disabled - I know this as I had it disabled! I prefer the Google calendar, so I disabled the HTC one. On this ROM you can only hide it, or backup apps allow it to be frozen, which is what I've had to resort to.

Well then since nobody seems to know what to do in our instance, and I have no idea if there is some kind of update for MaximusHD underway, we propably will have to switch the Roms. I usually had the mobile Data Transmission turned on all the time when outside my apartment and while it did drain the battery more than WiFi it still was enough for 8+ hours of being on with medium usage (sometimes with battery saver option ticked when I needed to be outside for a longer period of time). Now the phone would be dead after few hours.
EDIT:
Today I switched for ViperX Rom, and all of the issues I wrote about seem to be gone, Skydrive app no longer has any issues with connecting. Although I'll say something more about batery life in 2-3 days when I'll actually have a chance to see how it works. In general I can say that this ROM is a lot more customizable, and has lots of tweaks (greeat ones) I haven't seen in Maximus, but still I'll wait for a few days with my final opinion.
Ok so after using it for a few days I can tell that the ROM itself is just better in sheer terms of funcionality. First thing I noticed is that I can now put more than 16 shortcuts into Folders, the icon grid in app panel is 5x6 so now I have 3 pages to scroll instead of 7. WiFi seems work more stable but I can't say that it worked bad in MaximusHD. When it comes to battery drain while using Data Transmission - it's still there, but after a few cycles of charging it seems to get better bit by bit, if it still changes I'll let You know. ROM comes with lots of additional tools, and allows heavy customization, and reclocking the processor for better battery life. And that's just the tip of the iceberg. I don't know what about the phone turning itself on, because I don't switch it off. In terms of the callendar I also use gogle one and I just turned of sync options in the one provided by htc. Also I'm not sure if while installing the rom You are able to choose not to install the HTC callendar.

I've gone back to my old Orange-branded 4.1.1 / Sense 4+ build. Battery life has gone through the roof, HTC calendar is disabled, everything works, no problems. As for the phone powering itself on, well, something odd happened there...
When I decided to go back to the old build I restored my Nandroid backup and reflashed my old boot.img, taking the phone back to its old setup, and all seemed well, but that night I switched it off at bedtime (still find it weird that so many people think I'm freakishly odd for daring to switch my phone off from time to time) and lo and behold, some time later, it switched itself on again! The next morning I did some searching about removing the Clockworkmod recovery, followed the instructions, and also relocked my bootloader for good measure, and guess what? Since then it hasn't powered itself on while charging. So all I can gather from this is it was either Clockworkmod or having an unlocked bootloader that caused my phone to power itself on, because as soon as these two things were changed it has behaved normally.
So anyway, I'm going to stay on this build until Orange get around to releasing 4.2, or my contract expires in April, whichever comes first. Probably the latter, as according to a post I've seen from Orange themselves they reckon the update will appear 3-6 MONTHS after the manufacturer releases it.

Heh I'm alson in Orange (poland), and we got info that the update will show up sometime mid-december. I just got tired of waiting for them to update that's why I ended up with custom roms.
Maybe it was CM fault? I'm using TWRP, tonight I'll turn it off and see if it powers back itself during the night and let you know.
