Battery comparison

Hey,
there is no topic where ROMs can be compared by their battery usage, so I decided to open such a topic.
It's hard to compare battery drain due to the diffrent usage of your phone so I thought about using an app and a easy to reconstructable environment.
I would prefer this app: Badass Battery Monitor.
Environment:
Min. 6 hours unplugged after full charge, unused (perhaps at night).
Wifi off
3G on
Just post your ROM and ur battery consumption per hour (please calc also with the minutes, to minimize the faults.

Incompatible with my device!

I have my own criteria to appreciate the battery consumption. When I go to sleep, I read the battery level %. In the morning I read it again. That way, I noticed no difference between ROMs (locked BL, only stock, always rooted, bloatware removed, five ROMs tried until now, *.58 for the moment): around 3-5% per night. Always I administrate the radios manually.
Plus, *.58 version comes with a new stock app, called `Power Save mode`, with interesting options.

Was just an idea yet.
But 1%/h is a great performance...
If there are some more values, I'll make a list
Tried do flash blend kernel, didn't boot... how did u get that working? I also have GWK74 and latest Blend-kernel, but stuck at bootloader image....

Well, I'm still amazed too.
The only downside is that I feel like my battery is draining faster when I'm using my phone. So I should probably keep the tweaks for the deep sleep state and flash another kernel again.
I think your idea is great, I'm constantly searching for the best battery saving ROM and kernel.

Fixed: defy battery drain on 2nd boot defy

Hi,
I do not have enough posts to place this in the developer forum. However I update my Defy with each nightly build and since the 2nd boot nightlies I too have experienced really poor battery drain. I have fixed this by disabling two features in Google Maps.
Go to: system settings--> Google-->Maps and Latitude
Disable both location reporting and enable location history.
Instantly my battery has gone back to previous performance and after 17 hours I have 79% left. Previously this would have been less than 30%.
some people will not like this and it disables google now (actually make sure google now is also off) but if you want better battery life over these features this works for me.

I did the same and the battery consumption is reduced.
But using Better Battery Stats app I found out that my device won't go to sleep because of my WiFi. Wlan_rx_wake is always running. Is it the same for you ? Is there anyway to switch off WiFi automatically.
My config is same as yours.

No problem and thanks for the stuff in dev forum. This is post number 2 so maybe 8 more I'll be able to do it myself. There is still something else going on as I get occasional battery drain. My latest theory is around the method in wich you charge the defy or airplane mode itself. The last time I charged the defy from my pc via USB and I had amazing battery life and used 12% in 8 hours with some text and data and driving I.e. no wifi. Then it went to airplane mode and the next day the battery drain was significantly worse. So either USB charging is better than wall charger for some odd reason or airplane mode triggers some battery heavy process that never dies. I can't see this in the battery stats other than phone idle and screen. Turning off phone does not resolve either.
I'm continuing to investigate optios but my last full charge got 36 hours and had 19% left before I charged.

First of all, thanks for your findings!
I think that I found a workaround for the "something else going on" on the FAQ thread in a post by -=lov=- under http://forum.xda-developers.com/showpost.php?p=33159734&postcount=389.
Since I too am not able to post in the dev section yet, I posted myself in the FAQ thread (http://forum.xda-developers.com/showpost.php?p=33223114&postcount=398), asking that somebody gives a hint to -=lov=-'s workaround in the dev thread so that Quarx and the others can take notice.
Because I find this workaround important for everybody using the current custom kernel, I copy/paste my post from the FAQ threat to here too:
-=lov=- said:
If someone has battery drain in sleep mode, you can try to do this steps:
1. Reboot phone. Wait for 10-15 minutes.
3. Insert the USB - nothing happens on the phone. (Notifications Debugging and connect via USB does not appear).
4. Take out the USB.
5. Reconnect USB wait minute or so.
6. Take out the USB.
Now device should sleep correctly.

This is a really great workaround against battery drain in sleep mode! :good: :good: :good:
This method works very well for me and is always reproducable!
Before I had about 45 mA/h (2,5 %/h) while deepsleep during day (with 3G on) and about 30 mA/h (1,8 %/h) while deepsleep during night (by using JuiceDefender app, 3G and WIFI are off most of the time).
After appliing this method (which unfortunately has to be done after every reboot), i have just about 25 mA/h (1,5 %/h) while deepsleep during day and about 8 mA/h (0,5 %/h) while deepsleep during night, which are similar to the good numbers I had under Gingerbread.
BTW, using KSM, zRam and Swap don't influence battery drain, at least not significantly, in my experience. I got the above mentioned drains with KSM and zRAM enabled!
However, disabling "settings > location > access to my location" and "google > maps and latitude" options, as posted a couple of times on the development thread, *does* have some impact on battery drain, so I keep these options disabled.
I'm reading the development thread http://forum.xda-developers.com/showthread.php?t=1768702 for a couple of weeks now and unfortunately it seems that they haven't taken notice of -=lov=-'s great finding yet. I think that there is something about the USB drivers not properly initialized in the Custom Kernels yet, which leads to the much discussed battery drains. I'm quite sure that this should be fixable by Quarx.
Unfortunately, I cannot post in the development thread yet (actually this is my very first post because I found this topic this so important).
Therefore I would like to ask somebody on this FAQ thread to try this method himself and give a hint
on the development thread http://forum.xda-developers.com/showthread.php?t=1768702, so that the
developers and especially Quarx can take notice and finally fix the battery drain caused by the USB driver
bug (or whatever it is). :fingers-crossed: :highfive: :victory:

Hi @frpriot,
thanks a lot for forwarding the link so quickly to the dev thread! :highfive:
So far there hasn't been a direct response to the USB drivers issue (besides 1 or 2 thanks), but as always there are a lot of issues talked about on this main dev thread at the same time...
So let's wait and hope that the right people pick this issue up! If this shouldn't happen, it might be a good idea to give a hint in the thread http://forum.xda-developers.com/showthread.php?t=1908687 too, since Quarx seems to take part actively there himself. Could you in this case post there too? (I'm now still missing 7 posts to reach the magic 10 first posts... )
BTW, there already are some positive responses to the described workaround in a German forum at http://www.android-hilfe.de/root-ha...el-jb-defy-update-11-10-a-18.html#post4325150 ff.

I had a similar problem some time ago, with the phone connected to my home wifi network it would have unusual awake times, draining the battery very quickly.
I found out using the Network Log app (it's in the Play Store) that something on my network keep sending broadcast packets, that the phone would respond, thus the wifi wakelock.
That something was the NetBios name discovery service, enabled by default on Windows, but hardly used anymore, at least on home networks, turning it off solved the issue for me.

Thanks for this post. I have just plugged phone into USB attached to PC for 30 seconds. After only 10 minutes I can see the battery life has improved. See attached screenshot.Just after plugging in USB the battery stops draining at the same rate and the % has stayed the same.
Something gets triggered when the USB cable gets connected that stops the battery draining. I wonder if by charging the phone via the wall charger their is a process triggered that does not get killed when the phone is fully charged. By connecting to USB the process gets killed "nicely" at disconnect?

Hey I am currently on JB build 18.10.12 having 4.1.2 and the same kernel on which I had previously flashed 24.09.12 which had 4.1.1.
I am a begginer in this and have read a lot of posts before. But this particular thread has interested me more . Thanks for that but I still facing
1. Battery drain issues.
2. Battery doesn't charge beyond 79%
3. 2G toggle also doesn't work as soon as I switch it on it just says no network found.
The ROM is really good.. love the interface, hats off to those who did it..
Please can someone help me in this..
If u want any logs or screen shot will be posting it.

Hi,
Your kernel is not up to date...
First you should flash last update (update_for_18.10_v3.zip). You can d/l it on Quarx's ftp! After that you will probably have less issues !
Just try it and feedback.
Enjoy !

@fpriot said:

Yeah i did clean install it.
and i did try in the settings menu to use 2G always option.. it didnt work out.
well i will innumerate the steps i did -
1. after rooting my device i installed the CWM available on the JB thread 4.1.2
2. Switched off the device and charged it to 100%
3. Took out the battery went into recovery mode and reset and erased everything and erased the cache and dalvic too
and flashed the rom 18.10.2012
4. Upon which i flashed the V3 update as advised and then
5. lastly installed the gapps for JB
6. booted it up...
so far no isssues such as rebooting / loops, camera, wifi, etc with the rom except a few problems..its smooth
1. Always gets heated up when put on charge and talk at the same time or use it (which i think its normal i dont really know)
2. 2G still doesnt work..
3. Battery better after V3 update but not that much as before.. lasts a full day on conservable use.. wifi 3g 3-4 hours max but lasts a day
4. And lastly when put on charge again doesnt charge above 82%
dont know which step have i missed.. :/
love the rom though
Can you suggest me another rom which is as stable as this but with awesome battery life.. i also used a Samsung tab 2 a month back of my brothers it lasted about two days on moderate use.. wifi, 3g, music, games , everything..

Perhaps your bootloader version could be the culprit ? Don't know...
For battery drain issue, perhpas your battery is worn ?
For 2G issue, is it working with another rom ?
I advise you to have a look on FAQ section...
I can't suggest you another CM10 rom, i don't know another good ones...

18.10 is not just better and newer. It's way better. No lags. With v4, really good battery life. If your battery is not charging above 84, then take off the battery and wipe battery stats. Then you'll be good to go!

Terrible Battery Life

Coming from Playbook and old user of SGS the battery life is not good at all down 40% with 2.3 hours of internet any thoughts or is it 4.4.2 ?
Custom kernel ?

What does Battery Use say? You might have something else running.
You wouldn't happen to be viewing Flash, would you? I tried that once on CBS' site, and the resulting software rendering was a huge battery drain.

Are those Battery Saving Apps worth or just another drainer ? Don't see anything drastic in usage as its used by OS.

Check this thread:
http://forum.xda-developers.com/showthread.php?t=2381370
A lot of people (including me) are very satisfied with battery performance. Just so you know, you need a few charges to get a full potential from the battery.

I've had some issues since 4.4.2 too, and I'm no newbie to Android. I was disabling location in the quick settings and found that whenever I did that Google Search would keep the phone from sleeping. Please update with anything you find is causing your battery problem. As mentioned, these devices can give good battery life!

I don't play games on mine but I get between 10 and 13 hours screen on time every charge. Most of my time is on the internet with 3 emails syncing every 30 minutes and WiFi on all the time. I charge it every second night.

Rooting and installing a new custom ROM will help with battery life. I noticed on 4.3, the media server bug was present. I had to disable the media server scan. That helped a ton with battery. For 4.4.2 i use purity ROM. In on 2 days one charge with 49% left. You need to charge the battery a few times also as mentioned

Thanks but does this ROM enhances battery life or worsens ? Also what do you mean by Linaro ? Should i go 4.4.2 or 4.2 as per there post ?

4.4 2 introduced a bunch of security enhancements in light of NSA revelations. I cannot say how much better this ROM is compared to current stock because I haven't used stock for some time. That said, the dev is a very talented one and the rom is popular in a way a battery sucker wouldn't be. The rom contains enhancements over the stock version such as proprietary bionic/dalvic enhancements from Qualcomm that Google couldn't legally include, due to licence issues.
The main factor is in the kernel and the options it gives you. You can disable things like S2W, DT2W, magnet wake thingy, etc. You can also specify the maximum processing power when your Nexus' screen is off/on. Etc, etc.
At a certain point you're just going to have to see for yourself. The fact is that you don't like your current battery performance, so maybe just take the dive and try for yourself?
I will say your questions have been asked and answered a million times before. My earlier reply was the best I could do for you, my friend. For my part, I'm afraid you're going to have to do what everyone before you has done in order to learn more: ask Google before asking anybody else.
For example, regarding your Linaro question:
Try searching 'Android Linaro'
Question about bionic or dalvic? Try the same thing, maybe you'll have to adjust your search to include 'Qualcomm' (the brand of processor in our device).
If it's frustrating not having all the answers at your fingertips then celebrate! It's that frustration that will motivate you to find your answers.
For now, though, maybe start reading up on the links I gave you. There are ways to return to stock if you feel you need to (you'll also need to do your own reading on that).

Arguably, all the business of unlocking, rooting, flashing, etc. is probably easier on Nexus devices than it is or has been on 99% of contemporary or former Android devices. So, you're in pretty good shape off the bat=)

P.S. make sure NFC, BLUETOOTH, LOCATION (aka GPS) & WIFI are disabled in Settings when you're not using them.

Any recommended ROM or Kernel ?

The kernel is the most important when it comes to battery life because it Controls cpu and kernel and io operations.
I recommend using elementalx kernel because it has deepsleep state which will allow your device to save the most battery when you're not using it. I'm sure there are others but that's what I use.
The largest battery drain during use is the screen, so keep your screen at a minimum whenever you are using it if you're concerned about battery.
Another thing you can do to improve battery is undervolt. However you will only experience minimal benefit because you can only undervolt so much before your device is unstable. I don't recommend undervolting for newbies.
Another thing that can improve battery life is multicore power saving, a setting that is enabled with a custom kernel such as elementalx.
Another thing that I've heard that CAN help battery life is using Art, instead of dalvik cache. This is highly debatable, but some have reported improved battery life. I use art but mostly for the improved performance and load times, rather than the battery life.
Of course you should turn off anything you don't use, blue tooth, nfc, GPS, etc.. To help better manage this automatically you can use an app called profile scheduler.

Wizzle, I've heard ART isn't stable with apps that haven't been retrofitted to ruin with it. Is that your experience?

Incidentally, there's a new 'Glitch' kernel released today. Just checked and it also goes into deep sleep. You may want to check it out... it, too, uses the Aroma installer and seems to offer a few more degrees of customization. Just make sure you snag the right one as there are a few different builds depending on your rom source.
Which rom do you use?

I have installed the .AOSP Kangs][DJL4.4] ROM last night due to some reason some apps are closing on it. Will try out the new kernel.

Yeah, I have the same ROM and have used both ElementalX & now the latest Glitch kernel. Odd you're having force close issues, tho. Pretty sure that isn't something many others are experiencing. Do you run other mods? Is SuperSU working okay?

I'm on cm11. I've tried glitch, but not the latest. Most of the customizations glitch offers is basically more overclocking and undercoating, I prefer stock values for stability, I've over clocked before just to see how fast I could actually get my Nexus to work, but of course you don't get the best battery life..
I've had 100% success with art. It has not been unstable one bit. It's definitely faster and I don't have to overclock which saves battery.
One word of caution! If you sideload apps, sometimes they will no longer install once you enable art. Oddly enough if they were installed before art was enabled, it works fine! (hehe at least that's my experience)
Another word of caution, once I've enabled art, I was not able to go back to dalvik unless I deleted all my data and reinstalled apps from scratch.. I recommend doing a nandroid backup before you enable art, just so you have data that is dalvik..

My battery life is like what most people are saying, over 10 hours of use doing various things... other than 3D games with hour+ play sessions. Basically if I'm playing something like GTAIII or Final Fantasy III, battery life will go down considerably faster, but not devastatingly so, probably like 50% faster, and only while playing.
Here are some things that will dramatically help your battery life, assuming it isn't defective or something:
Having the brightness on auto or generally very low will help a lot. If you look at battery usage in Settings, you'll see that the screen usually eats more than half of your battery at all times.
Keeping GPS/Bluetooth/Wifi off when they aren't needed.
Closing background apps.
Turning the screen time-out down, which can be found at Settings>Display>Sleep. The Nexus 7 '13 has a pretty average battery, but one of its best qualities is how it barely loses any power when it's on standby.
Don't use live wallpapers or turn their quality settings down.
I'm using CleanROM which is just a stable, prerooted, more optimized stock AOSP rom and keeps up to date very quickly. My battery/performance is loads better than it was on stock. I couldn't recommend the rom more, especially after installing Xposed Framework and the GravityBox module, which allows you to to have many CM/PA features without much effort.

I get 10+ hours with WiFi and location on all the time. I do keep the brightness down a bit. If you're getting half that, something is wrong.

[HELP] [n900] BATTERY DRAIN PROBLEM after update

Hi I'm a Indian user
Last week I updated my note3 to xxuenf3 firmware then I had very terrible battery life
I'm getting just 4 hour on screen sometimes I get 3 hours :crying:
Guys please help me to increase my battery life
I don't want to root my device

May post your battery usage page to see what drains that much. The more experienced guys here may correct me but i guess without rooting there arent too many options to safe battery.

Thanks adding screenshots. As i thought facebook is an hughe drain factor as i see it also id suggest adjusting you screen brightness. Idc about uc browser tho

thanks for quick reply
i had set brightness to auto (-5 level)
what about android system it also consuming more amount of battery

The more experienced people can say more to that as me. Specially with your desire to not root your phone. There are as far i remember serval bugs causing system to drain more battery but i think it was way more than. Maybe search arroubd here for that bugs for more info about it could not be too wrong tho

thank how to root n900 ???
then should i install custom rom for good battery life

Added link
There are serval threads about that. Just follow the steps within thread step by step and youll be good to go. But read up within the threads about consequenses and risks. You wont need custom rom an custom kernel will do good aswell. I have nice experiences with ultimate kernel. Important to know is you have to read up if the kernel/rom is confirmed as working with exactly your device. For example international note 3 = sm-n9005
Here is an excellent written guide on how to safe up some battery

Ok I'm again here to solve BATTERY DRAIN ISSUES in pie ROMs (personally tested)

So guys .... I'm again here to help you all out to eliminate the battery drain issue in pie roms to very much extent ? ... So we don't need much mods .....
Things we need are here....
1.Nameless kernel by LibXZR ...im sure you all know this kernel ( all credits goes to it's original dev)
2.Nfs injector mod(magisk)
3.zuklineagethermal(for better gaming experience)
4.Galacticadeepsleepmod(by Pawan Rockz) which i personally use (you'll see no drain overnight when device in idle state ?)
Procedure.......
I personally use aosip rom and currently I'm still on it ... Well you can try on other roms too ... Try and tell me... But i recommend a clean flash ....
Ok so first flash rom,gapps as usual ... Now flash attached kernel,then flash attached zuklineagethermals,then flash Galacticadeepsleep mod which i provided and at last flash magisk .... Now reboot device let it settle and flash nfs injector mod via magisk and reboot ....and yes you're done .... Battery will improve gradually atleast test until 2-3 cycles
My secret personal settings?- Use any kenel manager like kernel auditor or exkernel manager and underclock cpu little cores to 1.3 ghz and big to 1.8 ghz ... Trust me it will not decrease performance of the device and set governor- schedutil and i/o scheduler to bfq(smoothest experience) ... Even it will reduce heating issues and improve gaming time..... Now let device settle and you're done....
Now things you'll notice ..... Seamless lag free experience overall ... No gaming lag ..... Improved battery plus no or minimal device idle drain ??
Plz hit thanks if it help you and please reply about your experience in this thread .......
I willl also post sot screenshots of a full cycle use after few time ?
Note : all credits goes to creators of all these mods
Everything is attached below so don't panic...
AND YES MY PHONE IS 2 YRS OLD with no battery changed?
ENJOY

So here you can take an idea about how well battery is going to perform... This is my totally normal day to day usage after full charge... No gaming .... already 3hrs+ sot And still 44% left so .... It's sure that I'm going to get 4.5 + sot and you can see the battery drain overnight is almost 0% ... I slept almost 7-8 hours

What is the advavtage of flashing NFS injector?
I don't want to flash magisk just for it

Bro .... Actually the default performance of nameless is a bit limited so you will notice lags here and there and mainly in gaming .... So the biggest reason to flash nfs is to eliminate the overall lag and get seamless performance and without compromising battery drain and it works 100 % that's why nfs is must recommend by me ... Otherwise you can check for yourself with nfs flashed and without nfs .... You'll see huge difference .... It's recommended strongly
