Hi,
Low Power Audio

Yep, I've already knew this, by asking what is it I meant how does it interrupt daily usage.

Hi,
LPA (Low Power Audio) Playback (broken in all JB roms, and has been for awhile, needs ION)

OMG, but I cant really understand what Low Power Audio mean. Show me some examples when i face it, like this - BSOD is when your screen is black after you try to unlock it.

Low Power Audio uses the ION memory mapper to save power.
LPA uses less CPU power by using the ION mapper instead of passing it through the Audio Flinger process.
Passing audio through the Audio Flinger process uses a lot more CPU cycles, which means the battery doesn't last as long as it could with LPA.
If you use Sense (3.0/3.6/4.0/4+) you'll use LPA when playing MP3s, FLACs or any other audio file. I'm not sure if CM9 or CM7 use LPA.
(For example, you can play music at 3% battery power for forty minutes to an hour with LPA. Without LPA, you could only play music for ten to thirty minutes.)

That just means that your phone will consume a bit more power while listening to music when the screen is off than it would do on ICS / stock ROM (the android version your phone came with).
So... not that big of a deal

And thats what I wanted to hear! Thanks guys. Could you say how big is that battery drain?

I found with LPA battery drain is around 3-5% with an hour of listening. Without LPA 8-10%. It's not exact as it differs depending on your phone and the amount of applications running in the background.

It depends a lot on various factors - whether radio is on and 3G is enabled, how bright is the screen, how loud is the sound, what player you are using, what bitrate and format, etc...
On my HD with 2.5G radio (EDGE) using manila player at minimal volume for ~192 VBR MP3 power consumption is:
- 224mah with screen on at minimal brightness; hence with standard 1350mah battery I would get about 6 hours of playback
- 170mah with screen off; hence with standard 1350mah battery I would get about 8 hours of playback

[Q] Which kernel is best for Stock ICS?

Hi, first to defend myself, I did search and found that everybody says good things for every kernel. So every kernel is best for Stock ICS?
I got confused. Yes I'am total noob and recently learned how to root and flash custom rom's.
I just want to hear your opinion for best kernel running on Stock ICS.
I need kernel that is good for the battery but also snappy for the system. I don't play games and I use my phone for calls, reading news, working on excel files, google maps, mail and taking pictures.
My phone is Nexus S GT-I9020T on Wind network.
IMO ezekeel kernels

Thank you. Is this kernel stable?
Im just trying to set it up as we speak, will let you know how stable it appears once I figure it out
Stuck on trying to flash an unsecure boot image at the moment.
*shrugs* The stock kernel?
Unless you want the functions third party kernels bring to the table, I don't see a good enough reason to swap the stock kernel for another.
That's what I was thinking. With Glados kernel I had problems with restarting after the screen turns of, also with Matr1x kernel. Also I read that there are restarting issues with IMO ezekeel kernels. Yes I know that probably the most stable it's the stock kernel, but there is problem with battery, I had more juice with GB and CMD 7. That's why Google paused ICS update on Nexus. But probably I will stick with Stock Kernel because for me it's better to have less battery for now instead random restarts. I hate when my phone it's not in perfect state.
Just managed to get ezekeels CFS on there and I get the reboot bug after going to standby.
Looking for updates but the thread is huge. Yet to try BFS.

You can try and turn off deep idle for your reboots.
Solves the problem 99% of the time (totally made up stat that could actually be true)
But actualy that function (deep idle) it's the most impotant thing in the kernel. It gives more battery time. Other thing are just fancy. More battery and no hickups, I dont need overclocking because I dont play games.

Deep idle gives more battery time under certain conditions (screen off but not completely idle, playing music for instance). It won't really give you more battery time if your phone is actually idle with the screen off.
But according to this http://forum.xda-developers.com/showthread.php?t=1297535 I understood differently. Maybe you are right, I'am still noob to all of this.

The first post that you linked actually just confirms what I said.
Ezekeel said:
Since this is just theory and Morfic noted that his experience seems to indicate otherwise and that limiting the CPU frequency does actually decrease the battery drain, I put this theory to the test and logged the battery charge over 10h of FLAC playback in Airplane mode with the screen switched off.

1) Playing FLAC (not idle)
2) Screen off
Pre-requisites are met.
So as I understood the battery consumption is reduced only if you listen music, because you can't do anything else when the screen is off. And the deep idle is working only in standby mode (screen off).

Deep idle only shows savings if there is tasks running while the screen is off VS the same situation without deep idle.
So for someone doing commuting (like simms22 for example) and listening to music for around an hour, they'll lose less battery with deep idle than without.
You won't actually save battery if your phone is actually idle with deep idle enabled.
It's not some kind of magical function that makes your phone use less battery doing tasks with the screen on, deep idle disables certain components of the phone while executing tasks with the screen off, instead of having it "at full speed" as if the screen was on.
Now I understood. Thank you very much.

No problem. I think Deep Idle is probably the mod by Ezekeel surrounded by the most misconceptions.
Most new users want it absolutely but don't seem to know why.
On His Glados kernel I noticed that Android OS was using 20%-21% of the battery and on the stock kernel 30%-31%.
Android System was using around 14% and on the stock around 19%.
Ok, have you decided to give the Glados 2.2 another go? I believe I have finally tweaked it so that it is stable for me.
Before I was getting restarts within 30 seconds of the screen turning off. I have cornered this (on my phone at least) to a problem with NSTools auto-setting the lower frequency to 100mhz. Changing it back to 200mhz and I have yet to see the system restart itself. Im not overclocked, because I dont see the point as everything is fairly snappy with this new kernel. I dont really play games on it so Im not fussed.
I did used NSTools and the frequency was set to 200mhz and I had system restarting on screen off. Using stock ICS with Glados 2.2
Also I had green annoying flickr on locking and unlocking the screen.

Tips for Best Battery

So guys, its a fact we have a small battery for our phone but I was wondering, how do you get the best battery life?
Just post anything! What ROM your using, what kernel, your kernel settings or maybe a tweak you found.
I want this to become a help center for people who suffer from bad battery
EDIT: Also, have you guys expierenced a difference with unfervolting?

Try Greenify in the Play Store. It seems to help for me.
I use a Tasker profile that will disable mobile data when my screen is off and when it's not being used. Don't know if it helps or not I don't worry about battery because I have a a portable battery pack charger thing

I wholeheartedly believe in Greenify! I have it on my tablet and phone. I've seen a jump in battery life by about 30% since installing it. Not sure if you will have the same type of luck or not.
There's many factors that can be affecting your battery. More importantly it depends on the type of rom you are using, assuming it's sense based... Try using elementalx 6.6 kernel, it'll help your battery; tweaked with the right settings. Power saver also seems to help a bit.
This probably isn't what you had in mind but my best tip is to keep my old iPhone with me and use it for media consumption. That way my android always has a full battery for actual getting work done.

Why not just Greenify maps as suggested by others. Did wonders for my battery life, used to go to 15% in the evening, now regularly above 60%. I also use autostarts to kill some other processes that are launched by default
I'm using the stock Android 4.1.1 ROM unrooted. With my normal usage, I can get through two full days. I make sure to toggle off WiFi and mobile data when not in use, as well as toggle on the "battery saver" built into Sense. I also turn off sync for everything (Facebook, Twitter, etc) except for two Gmail accounts which only check for email. It's about on par with my old Nexus One that I moved from. Keep in mind, however, that I just got the phone and these might change, but this is what I've noticed thus far.
A combination of 2xBattery (toggles data connections when screen off) Tasker (toggle data in different times/locations) and Greenify.

When it comes to battery life, the basics really are the most important.
here's a couple:
1. Don't use auto brightness. It tends to keep the display super bright even when it's not needed. The display may very well be the component that draws the most power in the entire phone! Look for widgets that let you select manually (I use "Brightness widget - backlight" from Google Play and even manually, I set the brightest it can go to 79%) or apps that still let you have auto brightness but more controlled (Try "Yet another auto brightness" from Play Store).
2. Use a setup as stock as possible. I know some people are going to disagree with me , but having your phone as close to stock as possible will have the best proven battery life. I think some of the developers here do amazing work on custom roms and kernels, but when people report good battery life you should keep in mind that are so many factors involved that it's hard to replicate it if you want to. Carriers test their phones extensively to ensure good battery life, and while I am NOT saying custom roms and kernels is a bad idea, I AM saying that I believe a stock experience is a more proven option.
3. It also has been proven that undervolting does NOT help with battery life because not only the difference in millivolts is negligible, it may cause instability and finally a reboot, which just happens to be the biggest software-related power drainer.
Hope this helps
im running clearrom 6.5 but i havnt been able to get greenify to work really. when i install it, it only shows a couple apps that i dont really use to begin with. correct me if i am mistaken, but greenify will hibernate/shut off running apps and the apps that the greenify app shows are apps that are currently running?
Correct. If the app you want to hibernate isnt running you would have to run it to add it to the hibernate list.

I don't know if I agree 100% on that one. Undervolting can reduce the amount of heat discharge caused by too much voltage being provided. A hot battery affects battery life both in the short term, and the long term.
Yes, not all phones can handle undervolting (because they're already receiving a good amount of voltage out of the box), and will glitch and reboot, which drains battery.
But, for phones like mine (which I can generally UV by about -75mv without adverse effects), the reduction in heat can only be a good thing for my battery life.
Sent from my Evita using XDA Premium
Heat itself should not cause your battery to drain quicker. Heat is moreso an effect from the cause of something causing the battery to drain rather than heat causing the battery to drain faster. Heat can damage the battery which would cause it to drain faster... so what I mean to say is heat will often accompany the battery draining quickly but not be the cause of it. Hopefully this post makes sense.
Sent from my HTC One X using xda app-developers app
Yeah it's the damage caused by heat that I was talking about. I've heard a hot battery will discharge quicker though. But heat is also a side-effect of the battery providing the CPU with too much voltage, that extra voltage being provided has nowhere to go so that energy ends being dispersed in the form of heat. Which in turn damages the battery.

That is mostly incorrect. The voltage options we can tweak are not enough to make such a big difference, so you can and will still experience heat even with an undervolted cpu, provided the load is the same. And that's my point, that the difference in undervolting in millivolts is negligible yet one reboot can wipe out an entire day's worth of battery life "savings" from an undervolted CPU.
Ok well all I can say is UV'ing definitely decreases heat for me, particularly when playing games (which is when it heats up the most), and I can safely operate without reboots. Before you say it's a placebo effect, I check my temp regularly to verify it.

[Q] HTC Sensation XE Heating problems?

Kind of a noob here but I got my HTC Sensation XE back from repair not more than a week they did a software update and I'm on the stock ICS ROM with HTC Sense 3.6 I think 3.33, anyway, using it for 10-15 minutes by just browsing through the homescreen or settings makes my phone warm up like crazy, to around 52 degrees celsius it's not yet uncomfortable whilst holding but very annoying. When I play for example Lazors for 10 minutes it heats up to 65 degrees celcius. Is there a ICS build I can use to lower the temperature, or should I undervolt and underclock my phone, and how do I go about doing that, or very drastically, send it back to HTC since it's still under warranty? Also tried CM10.1 build by Albinoman1987 and the phone heats up just as fast as on the stock ROM so I think it's a hardware fault. Any help on solving this would be appreciated. Just for clarification, the part where the SIM and SD card are located gets this hot NOT the battery.

Well, it sounds like a hardware problem, but I can't really tell you which part is the problem. I'm thinking that the CPU is overheating, and that my suggestion is to try different kernels, and to compare which keeps the CPU the coolest.
You can also install CPU tuner to view the temperature of the CPU and battery.

Since you're using the exact same thing could you do me a favor? Install System Tuner pro on your device and use it by randomly browsing through settings and homescreen, don't launch apps, just use the phones basic functions, do that for 20 minutes, and post your temperature, my CPU gets to 53 degrees Celcius doing that, also my CPU1 is offline and CPU0 runs at 1GHz instead of 1.5, if you do have both CPU's online, it's already a hardware issue. And play angry birds for 10-15 minutes or Lazors, doing that brings it to 63 degrees celcius, if you have lower temperatures, I will send it to HTC immidiately.

Do your soft buttons get warm especially the first 2? Cause mine does, but no matter, after the weekend it's being picked up by HTC for repairs. It's quite a shame, I got it for almost 2 weeks now after repairs and I can't do anything with it for too long. Although the weird thing is, when System Tuner Pro says 53 or 63 degree celcius it doesn't feel any warmer.

Heat and battery drain when listening to music

Big problem here, my battery is being sucked by mediaserver and google play music.
Everything off (3g,WI FI, bluetooth) my nexus 5 is using 960 MHz just to play music in background, screen off. This causes a huge heat too. Any suggestions?
POSSIBLE SOLUTION Update to 4.4.1
No one cares?
Are you using Google Play Music?

heat.. what cpu temps are you talking about? heat can be relative if youre talking about how it feels. feel isnt a temperature reading. and if you are using google play music, then the mediaserver battery drain is normal.

So, it's normal that in about 3 hours my battery was completely discharged because i listened to music. Cool. Trust me, i can play most of games without heating up my phone like that. And what's about qualcomm special chip to play audio without using cpu? I guess it's there just for fun. Really, my galaxy nexus was able to play music for days without draining battery and being hot. Are you REALLY sure is it normal?
Nope something is wrong. Perhaps a bad app??? I've only ever used Google Play music on this phone and have never had this issue. This is including streaming music over data through bluetooth while driving with Viper4Android running for eq. Phone will usually run at 300MHz when listening to music.

The problem went away when I installed faux's kernel and used his intelliplug and interactive gov, but it caused the music to skip occasionally and if I use chrome while listening to music, the page scroll is VERY choppy. I think it has something to do with the hotplug driver. So my guess is Google music is simply having bursts of very high cpu usage. Also, I listen to FLAC, so that could be it, but flac was made for simple and quick decode so I doubt it.

Nevermind however, it may sound strange but i think 4.4.1 fixes this issue and that the build brings specific optimization (new drivers?) to use that qualcomm chip (i think it's called DSP) instead of the cpu when doing minor things such as listening to music. Even if media server is still using cpu, i'm not able to reproduce the heat and the abnormal battery drain that i had in the last few days with 4.4. I'd like to say that the issue is solved, but i'll wait a couple of days, just to be sure. Meanwhile, everyone who has this issue may consider to update to 4.4.1 and see what changes

Ok, it seems fixed. Here are some screenshot after my "usual" 3 hours of music playback...even if, as you can see, the first part of the graph (from 90% to 75%) shows a faster battery drain (i felt some heat too). The second drop (70% to 60%) was due to me since i used data, but music playback didn't wake up my n5. Also, i noticed that after the first drop, my phone didn't use the 960mhz CPU freq, it ran only at 300mhz

Are you using FLAC files as well? Also your pic says 404 error.

Nope. I'm using only mp3s. I'm sorry for the screenshots, i'm having trouble updating them from my mobile. Here you are https://www.dropbox.com/sh/5vdw46ssh5f589s/O-SJ3WWyWW
