[Q] Knock on and battery life - G2 Q&A, Help & Troubleshooting

I just got a G2 (vs980), and I'm about to put Cyanogenmod 10.2 on it (after no amount of crying and screaming before figuring out how to update the 10.2 zip with new loki bits). I was wondering, does anyone know if the CGM knock-on feature eats more battery than the stock rom's version?

knock on doesnt eat any battery

I haven't used the CM knock-on on this phone, but on the nexus 4 it ate 1% per hour, at least double what it ate when off.

Cm is still buggy on the vs980. i would wait out the 5years Verizon will take to finally update to kk first.
I'm surprised that the att and or tmo kk builds haven't been ported yet.

That's because it wasn't supported at a low level like it is on the G2. Other devices it requires a wakelock or partial wakelock.
As for the OP, no, knock-on uses immeasurable battery. Some people say that I believe "Android System" usage drops if you disable Knock On but I have yet to see anyone show any real information that it changed battery life.
I'm not a heavy user but I take my phone off charge at 7am and put it back on at 11pm and it's at 80% or so most days. I could easily go two days, but I'd prefer the more shallow charge cycles to make the battery last as long as possible.

The custom code for CM doesn't take advantage of any of the low level stuff. It just keeps the digitizer on all the time, even during phone calls.

I'd have to assume that CM and other ROM kernels use the same code for knock-on as LG's kernel has, but maybe I'm wrong.

In my specific case, disabling Knock ON/OFF has improved battery life significantly, dramatically, from 49% drop (from 100 to 51) over 8-hour night (doing nothing) to 2% drop over the same period of time, again, doing nothing.

Yes, it's been around prior to it, but that doesn't mean that the kernel for the G2 isn't using something better than the old one that caused wakelocks... I searched the CM gerrit quickly but didn't find anything.

I've seen .4% sustained drop per hour on wifi at my house idle multiple times, on AOKP 4.3. I've never even considered disabling knock-on.

Battery problems? Google lies?

So I found this great app that tells me how much life I have left on my battery. I find that with my phone I can hardly go pass 16 hours with MODERATE use yet everyone here is bragging about easily passing 30hrs with HEAVY use. So I'm asking you guys, to please, download this app called BatteryTime Lite and post your pics or info here. Lets compare the results. Remember to set the level to 100% as shown in my pic below..
Also I herd the P/N might be related, mine is 99HKE002-00 F ..Guessing F means Failure.

Thats what I herd too..thats why I'm also calling google a lier about saying this thing lasts 20hours with audio playback.
I'm curious, do they see a big improvement in battery when the display using 15-20% battery or its just numbers that were out a place to begin with?
I have identical figures. That combined with picking the N1 from a list says to me that these are just database figures rather than real world ones for your handset.
Root your phone and then install cyanogenmod and one of the under volted kernels. I usually get 24 - 30 hours battery life.
I just ran a test. I left the mp3 player on all night turn all the way on repeat. SO far after 8hrs of playing I was at 52%. If I'm correct, I just might be able to hit 18hrs...MMMM

No problems at all? no 3g issues?, battery only lasting a day or half? or touch screen issues?
Ok after 100% charge..the app is telling me that my phone will last 10hr:48min with moderate use....anyone thinking that the F on my P/N might mean battery sucker..
i have the exact same numbers as you. if you choose other instead of the phone type it asks you to enter your battery's info so it sounds like it only goes by the type of battery anyway. Not actual usage specific to your phone
My phone ends in an F as well. My battery life SUCKS right now. I have tried everything. The weird thing is it was good until I rooted my phone and applied Cyanogen rom. I've tried .2 and .3 for the Cyan rom's, all with bad battery life. I've tried wiping batterystats, fulling draining battery then recharging, task killer to wipe anything in the background, I even have a 2nd battery. No luck. I've also tried the undervolted kernal, but I didn't really notice a difference with it. (Only tried it for about a day so)
Bottom line though, something is going on. Something (I suspect with Cyan's roms) is killing battery life for some of us. I just wish I could figure out what it is.

Any chance you're using Weatherbug or Weatherbug elite (based on your SS)? After installing weatherbug and using the widget I got absolutely ABYSMAL battery life. I've purchased several other weather widgets and none had the effect that Weatherbug did for some reason. I removed it and battery life is back to normal again (moderate use and plenty of battery at the end of the day).

How long your battery lasts definitely depends on the apps youre using, I use my phone a lot, probably more than the average user, although i dont make many calls. My phone will easily last from when I leave my house around 530am till 11pm or so when I go to bed. I do use a task manager to kill stuff I dont need running every once in a while, I think it really just depends on how you use it. I use it for a lot of texting, surfing and news, and Pandora at work. I use wifi when im at home although ive never noticed it eating my battery. Yesterday I was playing Pandora over bluetooth on 3G for a little over 3 hours and it only took 5% of my battery. Im on Cyanogen 5.0.5.3, if that matters. With all that said I rarely go all day without charging it, I usually plug it in a bit at work and plug it in when I get home, but if I dont for whatever reason it easily lasts my whole day.

Battery drain behavior

Hello,
Just trying to figure out if my battery is normal.
With any ROM OR KERNEL combination here, I tried few, my battery is fantastic while phone is idle, no loss over night or all day if screen is off.
But once I start using the phone it drops like 3-5 % from few minutes regular use, yesterday I took few photos, sphere, panorama and it dropped 25%. I have max1350
Wake locks are OK, no stupid stuff eating at it.
Is this normal for people or?

Nah, that's not normal.
- Bad signal reception?
- Google Now & maps updating non stop? Other apps, like facebook?
Post a screen shot of your battery usage graph, will make it easier to determine.
Have a look at this thread as well http://forum.xda-developers.com/showthread.php?t=2107163 some people have been helped by flashing back to stock.
Was it always this bad?
The battery reporting is kinda broken. Add you say, it can hold constant when it should really be draining slightly, and then suddenly drop in one big go as it "catches up".
It's a common problem.

-I was thinking of signal, I think it's not so great at home, it jumps from 3g to H to H+, but it's like 4-5 bars. Not sure, is there an app to monitor the signal strength?
-I've been planing around so there are not solid stats yet. But I am running Liquid smooth I don't even have Maps. There no crazy wakelocks or apps running, otherwise even in idle mode I would loose power.
It pretty much been always like this, since I started flashing custom staff. Don;t remember on stock, as there is no batter % icon there, I reverted back to stock right now lets see.
What ROM/Kernel are you using? and have you done what that thread is talking about?

Yes pretty much, I would not say i drops in one big number, but yes fast so pretty much same.
For example, to post the Thread i went from 35% to 32% after being idle all night, but then One Hour Driving to work with BT on pair with car, text messaging and e-mailing it dropped 1%.
The big question, if it's common problem, meaning not on every phone, so does t hat mean it's hardware and I should be calling Google?
or
is it 4.2.1/Custom ROM/Kernel problem?
is there a thread or anyone I can follow on this issue?
Thanks

I was on that until yesterday. Try it with Trinity or Franco's kernel, see what that does.
Didn't do what the op claims in that thread but then again, I didn't have any issues with the battery..
My phone was behaving the same way. The idle time would be great...no percents dropping for hours. But then when I'd actually use the phone the drop was sharp.
Lately its getting better for me...its dropping a bit on idle but also at a much slower rate when the phone is used.
I hope it'll be fixed in 4.2.2
Also keep in mind that the rendering process in photosphere does that huge amounts of battery.

n00b here, need help with battery issues

Hi there; this is my first post so please go easy on me.
Bought a Nexus 4 which is my first Android device, but the battery life is bugging the hell out of me. Surely the screen should always be at the top, right? I left it to sleep overnight on a full charge to find that it had shot down to 60% when I woke up at 7 this morning.
I haven't rooted or flashed or anything like that, because as I said, I'm an Android virgin. I have location settings off, only Gmail syncing and the usual push notifications here and there. Nothing too fancy or strenuous.
Any help on how I can go around fixing this? I'm a little afraid to rooting/flashing/ROMs etc, because I've no clue what works best.
Cheers!
If your saying you left the screen on over night, meaning the phone never went into deep sleep.. If you slept for let's say 6 hours and the phones screen was on for that whole time it's normal that it went down to sixty percent battery.
Maybe I'm understanding your post wrong? Btw I cannot see the picture you posted.

Turn off mobile data and lower the screen brightness to 0 during the day. Also disable WiFi when you're sleeping. I also make sure all apps are closed using the app manager button on the far right.
Mine's been fine following this logic.
Oh sorry, I should meant sleeping overnight, whilst I slept cosily in my bed.

This is NOT the answer. His battery in the image has dropped 7%. If he hasn't used the screen much it is perfectly understandable that screen might not be a large percentage of that 7%. As he uses the phone more screen will use a larger percentage of his battery and Android OS will use less.
If he gets to the point where the screen is on for an hour or two and the percentages are still like this then yes there is a problem.

Actually No the "Screen" should not always be at the top of the stat list. If you use the phone more than it idles, then yes... but if you are like me, mine says "Phone Idle: 20%" (which is on top) and "Screen" is 4th on the list with 12% (Wi-Fi and Cell standby above it) [this is my personal phone, and I mostly use my work phone. hence the high Idle & standby]
I was having an issue with my phone running out of battery, with very little usage from it. I mean very little, I might make 2 calls from it each day, and respond to an email now and then. I found that an App was preventing my Screen from going into "Deep Sleep" or even "Sleeping" possibly. So I uninstalled all apps (well I only had like 4 additional apps installed), except for 2 that I need (Google Voice & Drive). Powered off the phone, charged it fully, then powered back on. Its been running on the same charge for 24+hrs now and reads 68% battery remaining.
So check the apps you have installed, some use background data, and might be causing problems...

And your phone is the definitive guide for what Android OS usage is? Maybe his phone woke up those services for a period of time longer than normal.

See now it is much easier to see that you actually do have a problem and what it is. You have the wakelock problem as you can see from Better Battery Stats which falls under Android OS on the other screen. It also appears that you have somewhat weak signal which could cause the wakelock to drain battery even more. There's not much you can do about that wake lock, some kernels have patches for it but those have their own issues as well.

Could I just install any kernel on stock android and be OK with it? As I've said I've no idea what's best for me; just something nice and clean that doesn't have issues like this. I live onsite where I work so my WiFi is pretty much on all the time if that helps in anyway whatsoever
I'm gonna let it run down completely tonight and charge it, but I don't expect it to help much.

The battery on the n4 seems horrible.
I'm completely stock I just got my phone yesterday, I charged it to 100% now its at 64% battery with only 47 minutes of screen on time.
on the s3 I would be around 83% with 47 minutes of screen on time.
I'm gonna unlock the boot loader and root soon and try Franco kernel I've been reading good things about it.
Sent from my Nexus 4 using xda app-developers app
The battery life on the stock kernel isn't great because the CPU management isn't optimized well. It ramps up the CPU (frequency, number of active cores...) very easily and keeps it there long, which removes the occasional lag but sucks more battery. Flashing a more battery friendly kernel would definitely help you if that is the root of your battery issues and not a badly coded app.
Franco's kernel is a very popular one, and very battery friendly compared to stock (and that doesn't mean you lose performance). It is the one I'm currently using. Most people report of screen on times of 4 or 5 hours. With not so heavy usage and wifi (not 3g) I can also pass 5 hrs.
To install a kernel you need to unlock your boot loader and install a custom recovery. No need to root, but.. why not since you're at it
You can try different kernels with the stock ROM. You don't necessarily need a custom ROM. Just be careful to read the dev's OP and instructions, and definitely not to flash a kernel for another device.
Also another thing that reduces battery is your mobile data, if there are a lot of programs that sync on the background. You can use a program that turns off your mobile data when your screen is off and switch it back on just for a sync every xx minutes. Juice Defender is such app, though I like to use Tasker for that. If you use Tasker and are interested in that project, ask or send me a pm. It works great.

Nexus 4 battery the first week

Hey guys. I'm wondering how much better the battery has gotten since the first week y'all got it, to now.
For me I'm satisfied with the battery and I've had it for 4 days. I get about 2-2.5 hours screen on time with fairly heavy internet usage, texting, etc.

Are you taking any measures to save battery life, like certain screen brightness, disabling of certain features or radios, undervolting or CPU/Governor changes, etc?
First thing I installed on mine ( haven't had mine a week yet ) was Battery Monitor Widger Pro, since I've used that on my past devices when I was testing out generic batteries (speaking of which the 8$ ebay 3800mAh on my Desire-Z is still kicking strong after a year).
Problem with estimates, is that they are basically just that, and the difference between browsing on mobile vs browsing on wifi or mix, and your reception quality can also have an impact on your battery. (in the end, your screen is the biggest impact).
Mine lately, say if I had it charged at 100% , it'll take about 2 hours on mobile to get to 91%, with the screen being on about 25%-35% of that time (auto-brightness), receive/send text, take out of pocket to check email or facebook notifications, and so forth. Which would normally show as screen 30%, Google services 13%, Wifi 9% (when I had it on between house and destination). Phone idle 8%, Android OS 7% etc.
The widget I mentioned earlier can basically monitor your draw from time to time and if the screen was off or on and such during those times (default interval on it if using a widget is around 10 minutes on the logging, shorter may actually impact the battery it's monitoring oddly enough)
PS: The other day when I actually drained it down to 0% it took about 5-6 hours

Hey guys. I'm wondering how much better the battery has gotten since the first week y'all got it, to now.
For me I'm satisfied with the battery and I've had it for 4 days. I get about 2-2.5 hours screen on time with fairly heavy internet usage, texting, etc.

I had about 3-4.5 hours of screen time other moderate to heavy usage on my first week as I was testing it's battery life. As that I just used my phone under light to moderate usage. My brightness level is always at it's lowest but when I'm outside I turn it up to about 50%. I rarely play games on my device. I read a lot on my phone. I use my phone to record lectures in class and do a bit of homework on it. 7 months later and I'm pretty much doing the same. I have a custom kernel installed and I'm really confidence about it. I carry a external battery pack with me all the time but I hardly use. After having a custom kernel for the past 7 months I can say battery life has been relativity the same screen time wise. I learned how to manage my apps so they won't prevent my phone from sleeping to save power. Your mileage will vary depending on what you're doing on your phone and how you manage your device. Cell service is crucial to the phone. If you're in area with little to no service your device will use up more power to stay connected. This is when "Airplane mode" comes in handy.

Are you taking any measures to save battery life, like certain screen brightness, disabling of certain features or radios, undervolting or CPU/Governor changes, etc?
First thing I installed on mine ( haven't had mine a week yet ) was Battery Monitor Widger Pro, since I've used that on my past devices when I was testing out generic batteries (speaking of which the 8$ ebay 3800mAh on my Desire-Z is still kicking strong after a year).
Problem with estimates, is that they are basically just that, and the difference between browsing on mobile vs browsing on wifi or mix, and your reception quality can also have an impact on your battery. (in the end, your screen is the biggest impact).

Nah. All stock, not rooted yet, auto-brightness, No auto sync. I don't get very good service at my work and I was about 28% without service during the time I was there. I would get on facebook and message people on facebook and text, surf the internet etc because it was slow. I had maybe 2 hours screen time and 8% battery life when I left work. It was probably 9 hours off the charger. Here. I'll post a screen shot after this post (On my computer right now)

One of the benefits to custom roms (though 'stock' on a nexus is well AOSP so...) is the ability to tweak that stuff to finer details, top it off with a custom kernel and can optimize even further. Just a matter of how far you want to take it.
I have a history of immediately rooting anything I get my hands on, so I tend to have very little experience with stock. But the Nexus devices are probably the only ones I could survive having stock (but rooted) as opposed to say touchWhiz on samsung.
I can say that this phone charges FAAAAAAST.

At least all the available kernels work just fine with AOSP. (Francos seems to be pretty popular for battery, I prefer bricked though on both my N4 and N7).

Guess tonight I'm going to work on getting it drained down to 0% just remembered it was my N7 that I did a full cycle on with monitoring, I haven't done so yet to the N4.
PS: I usually do a dual-graph (mV and mA), but in this screenshot you can see generally speaking with my current configuration, I tend to drain around 200-300 mA screen on, and around -20-50 with it off.
PS#2 : It only went up to the -400 or so mA on the top right because I had changed my screen brightness to about half instead of autobrightness.

Additional options. Take for example the Bricked kernel for the N4 in my signature. This is it's feature list, it's not aimed for hardcore overclockers or such but gives you some options (The one for the Nexus 7 is a bit more configurable during the installation).
* Based upon Googles msm 3.4 source
* Various other fixes (look @ github)
* Compiled with gcc4.7.2 toolchain (linaro 09.12)
* -O3 optimized
* Snapdragon S4 & CortexA15 optimizations
* Sweep2wake
* 192Mhz min clock
* replaced qcoms hotplug binary with msm_mpdecision (IN-KERNEL, better battery life + performance)
* Extensive sysfs interface for mpdecision with all the tuneables you want (/sys/kernel/msm_mpdecision/)
* replaced the thermald binary with my IN-KERNEL solution. (/sys/kernel/msm_thermal/)
* export krait version to: /sys/kernel/debug/krait_variant
* modified ondemand governor
* Allow OC up to 1,83Ghz, faux123 (from a thermal point of view that is now SAFE)
* Fixed min cpufreq resets
* Undervolting (faux123)
* Default clocks: 384min & 1512max

Sweep2Wake is kind of nice too, you just slide accross the screen to turn it on without having to touch the power button (And yes your phone is still asleep doing this, it just works off interupts.)
other kernels can be a bit more involved, such as being aimed towards overclocking the CPU or GPU, or adding in extra features not normally found in stock, and so forth. I've had the best luck with Bricked and Francos'

Yep, if you have a widget on the home screen (I usually do 2x1 size) it'll collect every 10 mins by default. If you don't use a widget you'd have to check a box in preference to monitor without widget or it won't log times (note for example the missing 'blocks' from my history log).

Speaking of battery, anyone ever gotten more than say 800mA charge on their N4? Cuz even on my old Desire-Z if I plugged it into a 2.1A charger it would actually charge up around 1300-1500mA, but with the Nexus 4 seems that even on a 2.1A port it rarely charges more than 500-600mA.
It'll probably become more accurate once I actually drain it down to 0% and have the widget record it's history from 0% to 100% since it bases a lot of it's mA estimates off that (ie: off the rate of decrease of the battery's mv since batteries typically have a certain voltage once they hit near 0% and when they're at 100%, comebine that with what it knows the battery's mA to be it can determine the charge/discharge based off that).

What'd you say your screen on time usually was?

Just in the last 2 hours or so, probably 30-45 minutes. I was in the car so it wasn't coming on all that often. Since I actually have the widget on my home screen now, I'll just post an update again probably in the morning as I play with the phone some more, maybe play a game or two (I'll set a Market in the battery history before I start and after I end it).
Far as figuring it out, it's pretty easy since most of it is already set up by default once you open it. You can basically just pop a 2x1 widget on the home screen and just leave it.
My battery life has improved drastically by just sticking with one setup and letting the phone get used to it. That means keep the same rom and kernel so the phone settles in and gets used to it. After a few cycles your usage should increase.
I recommend straight CM 10.1 with Franco kernel.
Also use 2g instead of HSPA+ when you're not using data to save power.
If you're using touch control, don't, it drains more power for sure.
Undervolting helps too.

Can you clarify on this, other than the power/volume there's not much else to actually control the phone with.

The app 'touch control' , many nexus 4 owners use it to wake and lock the phone using touch gestures in place of the traditional power button. In my usage it definitely drains the battery quicker.

Oh you mean like Sweep2Wake in the Bricked Kernel I'm using, except that doesn't use any battery cuz that's in the kernel using interrupts rather than an app that would keep the phone awake. (course that's all it does too, wake, nothing more sophisticated than that).
But yea I didn't know about that app.

Gsam says Bluetooth heavy batery drain, system says only 1%

Btw It says 72% in 11 hours because i had the phone with justo the screen off all the night, but It normally says i have around 4 hours of screen time. But as i said in the title, gsam says that, it may be that im misunderstanding what the percentages mean, because my settings use of batery says another thing.
I recently flashed the Evolution X ROM, but It was the same with the oxygenos 11 stock rom
EDIT: i justo checked gsam percentages are how much time It was used, not how much of the batery It has used, so nevermind
EDIT 2: Still, i think 4 hours of screentime is still too low, could It be that my battery is damaged??

You are using a custom rom. I dont use this phone for a month anymore but the last time i used it auto brightness was broken on custom roms and no fix in sight. So display was the biggest battery drainer.
This was never the case on OOS roms.
Anyway for me the battery of the op8pro was some of the disadvantages. Im now using the Nothing Phone 1 and its like day and night.
Nothing is focusing on software optimisation and you can feel it.

I don't use auto brightness no I don't know, i always set brightness to 50% and pretty much never change it. Anyway, this custom ROM is amazing, is super smooth and one of the best experiences I've ever had with a phone. After some use the battery is not as good but it isn't bad either so i will stick to this until my phone fully breaks or something.

I guess the biggens drain was when it was supposed to sleep like being in your pocket or face down. The battery just click down no matter what I did. I did not let it drain since I am a full charge freak.
In contrast AICP barely uses anything when the screen is on AOD. My phone has been on for 15 hours right now and is at 47% with about 6 hours of use. I think if I didn't charge on the EVO X rom, it want last about 8 hours under the same conditions. I like the rom and wish I could use it but I have a weird feeling like I am being ripped off when my battery drains that fast.

Same, but the rom is so smooth and since the battery is still better than stock i'll keep this rom until i really need to flash another one because of the battery life
