[Review] My own short review of Juwe's Smart Edition v4.3.1

So I've flashed Juwe's Smart Edition v4.3.1 recently, and after some usage, I have found it worthy of a review. I must say that I really like it, and find it the best ROM I've used so far.
Here's the official thread in case you want to try it out: http://forum.xda-developers.com/showthread.php?t=964672
Juwe's is a JVH based, deodexed, CWM'ed, rooted/busyboxed(as usual) ROM with many more features. I found the following features highly advantageous:
Includes all Google Apps, which some custom ROMs lack
Includes Spare Parts+ and SGS Tools which have many cool features like script shortcuts, phone keypad secret codes, controlling window animation speeds etc.
As stock apps are deodexed, they can be safely removed and when they are removed, they can be backed up.
Includes Launcher Pro, which is CLEARLY the best and fastest launcher in my opinion.
Shows battery percentage on the notification bar, a feature which will please most users I presume
Comes with a black/white theme with some ugliness here and there, a good looking theme nonetheless.
A truly EPIC sleep animation, you'll understand when you see it
Very good looking window animations.
Includes an EXT4 filesystem converter which can convert /system /data /datadata and /cache to EXT4 and back to RFS.
Nearly all unlock screens available on any Android device can be chosen from.
INCREDIBLY low power consumption when sleeping (screen off, device on) compared to the stock JVH (it literally drinks the battery contents). Note that the HSPDA data connection is ON at all times.
Fairly low power consumption when talking on the phone (stock JVH consumes a lot of power on this task also).
Average power consumption when screen is on and the device is used. Note that window animations are fully enabled and Digital Rain live wallpaper is displayed on the background(which consumes a very large amount of power).
Average power consumption on WiFi, decent signal.
Amazing GPS. Absolutely fantastic connection speed, very low power consumption.
However, there are also some minor points that need repair or change:
Compass doesn't work.
Screen brightness seems to adjust itself randomly and poorly indoors, resulting in an abrupt brightness change every 10 seconds or so.
SGS Tools cannot find busybox?? Sorry for misreading, it says "If it says 'cannot find busybox' install it from the market".
The looks of the pop-up menus (accessed with the menu key) seem to lack that final touch.
OMG please replace that terrible bootanimation!
Note: The Android OS battery drain problem exists (as expected). This will only be fixed with an official firmware release.
Solution to the compass problem: Go to Settings -> Display -> Horizontal calibration -> Place device on a level suface and hit the button
There are also some other unfinished tests that needs doing:
Longterm WiFi quality/power consumption is not checked yet.
No "Gingerbread Android OS battery drain bug" encountered yet. Cannot be sure.
GPS is not tested yet, as it requires that I get off my lazy ass and go outside
Hope these observations clear the minds of people who consider trying Juwe's out.

Yes, Juwe has done a good job.
4.3.1 doesn't drain battery much. When I had other ROMs, the process 'Android OS' mostly needed 63% of the battery, with this ROM only 2 - 10.

Your problem being the one explained here http://forum.xda-developers.com/showthread.php?t=1039696, I must say that even without the drain issue, other/stock ROMs drain much power.

If you post the "defects" that you found (as well as this full review) in the original rom thread, I´m pretty sure that Juwe will be glad to help you.

However, I had this problem with lots of other ROMs (even with (Juwe's 4.3), but not with 4.3.1.
And I don't have any problems with busybox.
If you don't like the bootanimation, you can easily change it. Download one of the bootanimations here one XDA, copy it to your sd-card and copy the *.zip-file to system/media and rename it to bootanimation.zip.
GPS works great.

I know how to change the boot animation, I just think that this ROM deserves a slicker one.

Do you need a screenshot? Why would I lie about this?
Anyway, I tested wifi and GPS. Wifi is good, consumes average power but GPS is very fine indeed. I'm updating the review.

Been on Juwe's 4.3.1 for a week now. Only GB ROM I've used so far. Gotta say I love it. But for the last couple of days I have been experiencing the android os battery drain. Will be looking into it after I get home from my vacation.

Unfortunately, I too have experienced the battery drain issue today. I'm not too disappointed though, this is known to be a general JVH/JVO problem, and the fix must be done by Samsung/Google. Updating the main post.

Ok, I have found the solution to the compass problem. Updating the main post.

Thanks for th review mate. Wanted to try Juwe's ROM, will do it when I go home tonight.

Ok, I think I've misread the message given by the SGS tools, updating the main post.

how is the camera working?
and is there any problems with double market downloading?
also does it have an SNS Facebook sync??

com.android.phone batery drain

I have read little about this issue . Instead of renaming or deleting files can we make auto booting script to kill this process so it will no longer looking for a mobile data ?
I have no android skills so am asking somebody who have it. Maybe there is other safe way to ged ride of that battery eating cell standby process
Proudy owner of iconia
Pawel
PS
I have try
(Without doing nothing 50% SCREEN AND WIFI TOGETHER 40 % after change a charg iconia to 100 % and wiape battery stats)
2g/3g mobile data switching best results cel standby takkes only 35% battery
Kill mobile data and prevent to run almost same thing
Cheat with airplne mode same thing
Try to download from market a.k.a batery saver for acer iconia without any results (thor mod with i have is based on assus transformer and market shows incompatible version?)

Dear Pavel,
this is a rather old issue, solved long time ago. You can just add the following lines in your build.prop file, located in the system folder:
ro.carrier=wifi-only
Thor's ROM features this tweak by default so you don't have to do anything - no cell standby.

Well thor rom have this line indeed. And when U check settings about tablet battery indeed isnot showing .
When U install any other app to show battery stats actually shows cell standby and phone idle. I using norton utilities but few other ones shows.
I left for a night tablet screen off, gps off , wi fi on, airplanemode on and after 6h i have 15 % drop down. 8 H on my iconia possible when everithing is off.
Ps
Writing this post 3% down... and tablet was bought on black friday is brand new is that normal ?

If your tablet is new did you fully charge and then discharge the battery to about where it auto shuts off.

There are a couple of things to mention. If you are running an over clocked processor, this will of course use more battery power. Especially with thors roms, because the last time I looked, depending on version, it installed over clocked to 1.5ghz. If you don't need that much, try setting it to 1.2 for example.
Apps that are always running and synching. Things like weather apps, mail, fb, etc. And... those lovely battery apps (a waste of time). And this also includes Norton, as it runs as a process. All of these use battery power.
And as briandigital said, let the battery get a few full changes. Usually takes them about a week to settle down.

I agree with U. Those apps using battery. For example weather widget 0.5 % or norton 0.5 % but still shows 60 + % cell standby or 2% phone idle. wifi over night 30 % with checking mail every 15 min.
Over Clocking got nothing to do with this (1000 on screen on 400 on off) system proces phone is running all the time draining battery.
I have thor 14.2 mod and to get 100 % shure I flash again kernel and dubble chec for wifi-only line.
Wipe battery stats and 10 min after cell stanby 30 % after 30 back to 63 %
Or 5 diffrent apps from market are wrong showing cell standby and system process phone working and draining battery or this all solutins are not really working. If it not showing on /settings /battery is not mean process is not working
Anybody know how to kill that process and prevent to run ?
so can write small script to kill it"

I'll ask you a silly question.
And only because I didn't see it stated anywhere (or I missed it)
Are you running an A500? or an A501?
3g USB Dongle?
Did you run any "update patches" concerning 3g Dongle support?
Reason I ask, is that I did some of the testing for the kernel version you are using. (3.9r3). And frankly, I haven't heard a lot of 500 users complain about "cell standby" with the 14Rom. In fact the combo should be giving you extremely good battery life.
You said it only shows cell standby when using some other different application? I might suggest the app is not telling the truth.
Typically, losing 10% overnight with wifi on, is pretty normal. During testing, I lost 8% on internal 3g, and about 10 or 11 with Wifi. FB and Mail not's set to 1hr intervals. WX at 3hrs.
The fact you still have the menu system for mobile networks (2g/3g) is very puzzling......
Did you post this issue on Thor's site? www.tegraowners.com

4. Am not complaining about battery life, am complaining about stupid process what is draning my battery.
5. A can post 5 screenshoots of different apps whitch showing cell standby process draining battery. Whatever i will download from market kit is showing same so i believe they're not wrong.

You should re-think about posting on Thor's site. He's typically pretty responsive. Unless it's a stupid question, or somebody's not nice.
The cell standby issue is an old one. It's because the 500 and 501 share the same hardware with the exception of internal 3g for the 501. And because of that, the share mostly the same OS code.
Thors rom, was based on the asus transformer. I don't run it, as it doesnt fully support internal 3g.
It's possible, that the process is still running, only hidden from view based on the images you supplied with the modified build.prop set to wifi-only.
In this case, I would ask you again, to post the issue on Thors FORUM under the Rom ver 14 topic. It may take him a day to answer, as he's working on ICS right now.
In the meantime, here at xda in the a500 forum, there are several "older" topics covering cell standby on the a500. One of the fixes at the time, was to "freeze" the telephoney.apk (get some error messages) then reboot.
Just do a search for cell standby, and you'll find them. I found them earlier today through Google (but can't remember where), so you should be able to do the same.

Well I did some research before I bother U and other solutions is to rename / remove phone.apk witch may solid brick my acer. Am wonder if I rename it and hard reset can I be able go to recovery ? And restore prev backup or this is gonna be a perm brick
Sent from my HTC Vision using xda premium

Well Pavil, those posts are a little old.
And, sometimes people call things a "brick" when they really don't know what a brick is
BEFORE I would rename any apps, I would try this, Install Titanium backup. Once installed, and root granted of course, Select the telephony apk, then do a "freeze" on it. Reboot and check things. You may want to freeze those other couple apk's if it doesn't fix it. You will probably get some error messages when you first freeze it, but ignore it, and reboot.
But BEFORE you go freezing things, do a recovery backup first This way, you can get back to where you were before freezing.
Then see how things go.
EDIT. Stop using battery apps designed for phones. They may run on Honeycomb, but if they were designed for devices that have a functioning radio, they know no better than to display an erronous stat.
But honestly, battery stats in android are somewhat misinterpreted.
Example. If your device used 10% power. And the stat says Display used 80%, It means that of that 10%, the display was responsible for 80% of it. Not 80% total battery power.
In the meantime, I see you didn't post on thors site? Ok, I'm on good terms with him, so I'll pose the question to him.

Thanks for interesting of my problem. I try today to ps ,get pid and kill but this buster is restarting by it self...

It appears from your screen shots that you don't have your wifi set to disconnect when your screen goes off. I could be mistaken, but if it's not, changing that will help battery life immensely

Yeah, no sense in messing things up. A pity I don't have an a500 or I'd test it myself.
You could try flashing one of the other roms, and see if the result is the same. For example Taboonay. I ran it for quite awhile with Thors 3.9r3 kernel. Or you can use the kernel it comes with.
Answer from Thor is that he's not aware of the cell.standby issue as nobody else has mentioned it, and all his stuff now is set up for ICS, so he doesn't have the time to check it out.
So, maybe you just have to live with it. Seems your battery life is ok, so I would just ignore it for now.

Did you wipe your battery stats from CWM before flashing?... And by the way thor's ROM has CPU clock set to 1.2 GHz by default.
p. s. Moscow Desire is right about apps made for phones.

Yeah, he had to back off the original cpu install recently due to a couple users couldn't flash at that speed (1.5). Not all CPU's are made equal.
(the real issue here, is the old "cell standby" issue that a500's had in the past)
But again, like drkalo affirms, you shouldn't be using battery apps that were designed for phones running android 2.3. I suspect (considering nobody else using Thors roms complain about cell standby), that the phone battery apps have this hard coded, and expect it to be there, so it displays a random percentage. Probably because it see's the phone apk's in the OS and naturally assumes it needs to display something.
Yes, the apps will mostly function on Honeycomb, but, are they really made for tablets? Probably not. (even if they say it does).

So what to use to check ral battery / process usage?
Sent from my EPAD using xda premium

Personally Pavil, I do not use one. Except what comes in the rom. There's really no need to get anything else. And frankly, I don't hear a lot about folks running 3rd party battery apps on their tablets. So I'm not going to be much help on suggesting one. I just know most of the task and battery apps, were designed for phones on android 2.3.
I gave up on things like battery apps, task killers, task monitors and the likes a long time ago. I learned to manage things on my own like most others do. There's no reason, once you learn a little about how android works, to add apps that take even more resources.
Bottom line, you can have every app in the world to monitor things, but what really matters, is what the "actual" battery life is.
For example, I can go 12hrs with normal usage, and still have 60%. This includes internet, sms, mail a few times, maybe some video for an hour. It depends.
Or, I can play angry birds 7 hrs straight before recharge. Not bad! And I run my processor at 1500ghz.
You can instal a cpu app, like cpumaster, and set profiles based on how much battery you have left. I typicaly set mine to start at 1500ghz, then do 2 extras to down the speed based on battery. When I use them, I can run for almost 3 days with normal usage. I do this when I know I will be camping with no electricity.
I have 4 of these profiles on my phone, and the longest I lasted, was almost 4 days before recharge.
Wish I could help you more.

Battery Life BUG in ICS based ROMS

I've done a little research and there is a bug in the 4.0.3 AOSP release. You can see a link to this issue here: http://code.google.com/p/android/issues/detail?id=22878#makechanges
Attached is a screenshot of the problem ocuring in ICS Passion 13.1
I am curious is anyone NOT having this issue?

Yeah, mine started couple of days ago with the same problem. Android System shows 75% battery usage.
I wonder if there is a fix for this bug. I read whatever is on the link but there is all king of possible solutions.

I'm on MIUI and this is happening quite a bit too

Yeah, My battery will be 80% I reboot and it 10% or it's10% and I reboot then it's 80%...lol

I think, 84% is the culprit. Read my post here --> http://forum.xda-developers.com/showpost.php?p=23766036&postcount=2223

I used to have that issue on CM7 many moons ago. Did a bunch of searches and someone mentioned a process call GOOGLEBACKUPTRANSPORT.APK somewhere on XDA, that constantly runs even after you do not choose to backup to google (at least thats what I think its for).
I used root explorer to go into /system/apps and delete the GOOGLEBACKUPTRANSPORT.APK. I have never had any negative effect from doing it. It fixed the Android OS sucking up battery problem. Now I make it a point to delete it after flashing a rom regardless of whether batter drain is there or not. Never had that issue since.
Try it and see what happens. You can always just move it or rename it so you can put it back if it does not solve your problem.

Post to the Google Code bug

Just wondering if there have been any discoveries or new info on this problem.
I was experiencing this bug for a long time and I thought it was a bad battery. After replacing my battery it was still happening.

Battery life is the sole reason I went from ICS Passion (4.0.3) to Slim ICS (4.0.4).
I think battery life is better now, but I've also been incrementally restoring all my apps, ensuring battery drain isn't unreasonably affected with each restore.

I have this same issue! My battery lasted up to a day yesterday and today I had to charge my phone twice. Lasted only 4 hours. Pretty ridiculous I would say! I did try removing googletransport.apk and it reduced my android os to 25% or so from 60% that's about it.

Wow, this worked beautifully, thanks a mil illego.
Installed ICS Passion v13.1 a few days ago and had severe battery drainage, from 100% to 0% in 8 hours after calibration.
Looking at the battery stats I realized that the phone was always in AWAKE mode, with ANDROID SYSTEM sapping like 80%.
After renaming GOOGLEBACKUPTRANSPORT.APK the phone finally went into much needed sleep mode.
In hindsight, I enabled Google "Backup this Phone" during first ICS setup, and this must've tried to connect to the internet the whole time or had a process keeping the phone awake.
Brilliant fix, you made my day, thx.

I was using ICSSGS's 4.0.3 and noticing that my battery was draining pretty quick with little or no use.
I decided to try the Dark Knight 4.0.4 rom and my battery life has pretty much doubled.
No lock screen issues now either!

SlimICS!
I have been using SlimICS and have never had any batt drain issues. Googlebackup.apk is removed by default from this ROM.

I never get good battery life on a ics rom, tried on 3 different phones with 6 different roms. It looks nice but isn't battery friendly from my experience.

You must have one or more apps draining your battery.
User betterbatteryStats or "BadAss battery monitor" to check where battery is being used and whether any app is keeping the phone awake.

I agree
I have to agree. When I use a Froyo Rom my phone loses .5% per hour in idle. At times it loses a max of 1% per hour. However, with ICS ROMs I lose around 1.7% per hour. I have tried just about all ICS Roms, and all Kernels. While some are better than others, 1.7% per hour is pretty standard with any ICS. Trust me, I have no deep sleep issues, and no abnormal wakelocks. I've read all the post of saving battery life, and done them all. Roughly 1.7% per hour is what I get with any ICS Rom.
Personally, I like the look and feel of ICS so I just take the good with the bad. Can anyone shed some light on this. Why does ICS drain battery so quickly in idle vs older android versions. Or, is it just the Vibrant? Im stumped.

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.

Ok thanks, good to know that. I will remember if necessary....

An additional great workaround against battery drain in sleep mode!

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:
Thank you for your support!​

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 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.

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 !

Is 2g mode works if you select it in network parameters ?
Did you try a clean install ?

@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..
thanks a lot ..

I don't understand why it doesn't work..For me it works perfectly..I have a Defy green lens with last 1018 rom + v4 update...
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...
Did you try CM7 stable roms? If yes, have you got the sames issues?

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!

Android 6.0 Marshmallow battery discussion

This thread is for battery life discussion of android 6 Marshmallow.
I took the plunge recently and installed cm13 nightly on my phone after a couple of days with sultan's cm13 ROM. One notice that the android team really got the battery optimisations right this time especially when coming from android 5.1. The cell standby and android system bug is now gone and the phone can now be in standby for a long time. My usage pattern is browsing, reading in Adobe reader, listening to mucisc with bluetooth headphones, facebook, wassup, some youtube videos, sms and few calls. I play farm heros sometimes but I don't play graphical intensive games.
Here are 2 screenshots of my phone. It was charged to 100% at 8:00am on 30/11/2015 and it still has 41% left as at 10:00am 02/12/2015 Granted I have only used it on wifi and I configured wifi to automatically disable 5 minutes after the screen is off.
You can post you battery life too.

If a moderator deem it fit, he/she can close the thread but I felt it will be nice to make a dedicated thread for Marshmallow instead of looking through a big thread to get the relevant information needed for a particular android version.

yes.

It still sucks on mobile data. Nothing changed from Lollipop in regards of mobile data battery drain and i wish google could do something about it.

That's it! It's still on LP niveau

i had around 2 hours of screen on time and less than a day's battery life. The MMS also didn't work with WiFi connected, so I switched back to CM12.

I finally charged the phone today but not before I took a screenshot. My usage is not heavy at all so for heavy users, I guess the SOT will be longer but the total number of hours the phone was on will be lower. My usage did not change form that of 5.1 but I can definitely see a great change in standby time.

Still doesn't beat out KitKat in terms of heavy usage IMO.

The performance(yield) of the battery essuperior to android 5.1. The cycle of load lasts approximately two hours more of screen.

Sent from my A0001 using Tapatalk

6.0 has the same battery life as 5.x for me. about 4-5h SoT.
KitKat and early 5.0 builds were clearly better with 8h SoT

Currently running Sultan's ROM CM13:
My battery life has hugely improved when I'm not touching the phone, no one app is draining way to much battery while not in the foreground.
There is one problem some people including me have been experiencing which is that Wi-Fi doesn't switch of properly and drains the battery, the only solution I found was to reboot the device after switching it off.
Not sure if this is a CM problem or the specific rom but not AOSP.
But apart from that battery life is good.

On sultan CM 13 CAF
Getting 4-5 hrs of SOT

Still waiting on a fix for mobile radio active. Had to go back to KitKat after a year on 5.x and a week or so on cm13. The difference in battery is staggering. Here's hoping Google actually finds a solution for the drain, otherwise I'm gonna have to stick to KitKat until I get a new phone.

I dont worry much abt battery charge ..currently on CM13.. dont see much of difference ... expect charge to last for 1 day.. connect to charging when home

Tech guys suggest me best battery rom for OPO don't fun with me by saying cm11s 44s. Almost 1 year stick to cm11 I need some latest android version in my device,
I'm new to xda
Thanks in advance!

Just stole myself this glorious phone yesterday (not really.. got a smokin deal) after 3 years and a month on a Nexus 4 that was left stock the entire time. My OPO is already rooted/unlocked so I'm trying to test out and find the best rom for battery life as both of the cm lollipop and marshmallow roms I've tried are about equal in terms of buttery-ness and just stick with that rom indefinitely.
Is general consensus that cm11 kit kat is far superior to the later cm roms in terms of battery life? Which exact rom would you choose as the last rom you flash onto your OPO ever?
