[ROM] Atrix CM9 [ADT's SelfKANGish builds - 20120715]

Yeah! I have a teammate who just installed CM9 on his Atrix and he is able to get almost 2 days of battery with stock configuration.

I'm using faux123 kernel with SetCPU underclocking to 450mhz, keeping 3G and WiFi off, brightness on low and can't get more than 10 hours of juice :/

my battery life seems to fluctuate quite significantly. sometimes ill get the best battery life ive every had (yesterday for instance... ~1hr screen time over 13 hours and was only down to 60%) then the next day ill have horrendous drain (today ~1hr screen time over 6.5 hours and im at 40% already). im running the same exact setup, and didnt reboot between yesterday and today. the potential is there, and the ROM is incredible snappy and smooth, and the only nonstated bugs ive noticed are WWF-freeze and camera will spontaneously quit working.

as this ROM is in Beta, i can imagine that this will get ironed out with future releases, and i doubt battery life is the primary objective at this point for Turl and any other devs working on cm9.

*running Faux's 1gHz kernel, slightly UV'd, pushing 2 gmail accounts, auto-brightness

You guys with bad battery times... make sure you are turning bluetooth off when not using it. I was getting hammered when I left that on. Facebook Synch and other Social network apps had to be reigned in as well. After that I can get 36hrs with Exchange sync running.

I get an easy 2 days as well with 2+ hours of screen on time easily, even without any underclocking or undervolting. I wonder if some peoples' batteries are crapping out. I've had mine since launch day and haven't ever had battery life issues with it.

The information Erik posted is absolutely correct. Please review the below article with hard data to support his argument.

(Sorry I had to break this link to get it to post as I am a Lurker and never post)
h t tp://batteryuniversity.com/learn/article/how_to_prolong_lithium_based_batteries

The key data grid is the 2nd one. Dod stands for depth of discharge. The number of discharge cycles before the battery capacity gets reduced to a low level. In the first graph the tested batteries' (who held an averqge initial charge of 90 percent capacity) capacity was reduced to the mid / upper 70 percent after 250 full discharge cycles. If you mentally extend the trend lines for the tested batteries, its easy to see that they would be at the 50 percent level or so after 500 full discharges.

The moral of the story is plugin whenever you possibly can...

Because li-ion batteries in particular get stressed below 20%, hell, shouldn't even let them get that low. It shortens their lifespan if repeatidly drained. You are much better off just giving it a quick charge.

Just as an example, the Chevy Volts battery back will not allow the system to completely drain before the generator (engine) kicks on. This is designed to protect the battery and its longitivity.

Most li-ion batteries can support a "quick charge" as well. They can charge exceptionally fast between 40-80% usually, then trickle charge the remaining 20%, to protect the battery. This is exactly what most hybrids do.

doesn't the phone shut off somewhere around 3400mv anyway? so it's not really even down to 20%.

Mine is working great but with one exception, the camera always crashes, I think I saw a fix somewhere but now I can't find it

There is actually one more issue, Navigon 4 does not work either :-(

Any advice

Cheers

Camera issues here too. I searched the thread and so far only saw to install Camera Illusion. Didn't fix the issue for me. I'll keep digging.

Everyone has this issue.

erick161 · Feb 28, 2012

Does anyone have problems w/ the browser, be it the stock or something else like Boat? I get A LOT of crashes with the browsers. It seems @ 1ghz it will crash 10x's more than when i OC to 1.45ghz.

I havent sideloaded the new Chrome Beta APK yet either, so no experience with that.

EDIT: Same thing with the new patched chrome APK. touch the tabs button, crashes as usual.

batery

I have two days of battery life, (when not playing), all of you who have less than 24 hours of battery life have tried to "fix permissions"?, this has solved the major problems of battery discharge in some alphas CM7, I always do installed after all .. no matter what rom, I always have a reasonable battery ..

look, man, I do not advise you to try to resolve this problem, because in 99% of people work on any music player, right? then your installation problematic man, you formatted / system? (this can be invaluable at times man, I know it's bad to lose data, but it has to be done, I suggest you do a new installation

I always do in this order, and I have no battery issues and players:
* format /date
* format /system
* format /cache
* Wipe Dalvik
* install rom
* start the android, wait a few minutes (it works on backgrownd, doing some installations, even after you show the interface).
* recovery
* install GAPPS
* wipe /data/cache
* clear Dalvik
* fix-permissions

ps: I'm not saying you do not know, just saying how I do and I have no errors ..

be happy ..

Why do i keep reading that battery life is superb with V8 ICS9?
My battery lasts about 5-6 hrs then needs re-charging.
I would love to get a full day never mind 2 days like some are getting.
Any ideas please?

Download Better Battery Stats from XDA and gauge that to see if there is an app or process murdering your battery. I use my battery heavily during the day for the camera use, bluetooth and music playing in car and at the gym, and chatting on Weixin, and I average 30 to 50% battery remaining at bed time. Do you leave GPS or bluetooth on all day, or that crappy Facebook app? Something has to be torching that battery. If you can't find an answer from BBS, do a full clean wipe, including a fastboot wipe.

DJHile · Feb 28, 2012

Did we lose the ability to blacklist numbers in ICS/CM9? I know you can blacklist a number already in your contacts but what about those pesky telemarketers? I miss the ability to long press from the call log and then blacklist.

bluetooth sleep issue recap?

I'm on Turl's V8 (with faux123 1.3 kernel) and deinitely have the bluetooth sleep issue that others have mentioned on the forum. When bluetooth is on it keeps the device awake 100% of the time. (as reported by betterbatterystats) Has anyone figured out a sure-fire way to rectify this issue yet? I saw from this post on the other CM9 thread

http://xdaforums.com/showpost.php?p=22823760&postcount=4041

that moving the 6 files from that zip into /system/xbin has worked for some but I'm wary because I noticed 3 of the files (hciconfig, hcidump, hcitool) in the zip are already in /system/xbin and am not too sure about overwriting files with something from a CM7 rom. (the files are from neutrino) I did move the other 3 over (bdaddr, bttest and hstest) and set permissions, but it didn't fix the bluetooth sleep problem.

Has anyone overwritten the files in xbin with the ones from that zip and fixed the issue without causing more problems? Anyone have any other suggestions for possible fixes?

+1

to be included in the next CM7 nightlie is an update to the kernel... maybe this will help CM9 in some way....

This has been mentioned before. If you're using the latest version of Chrome, it's not compatible with CM9. You should rollback to a previous version and turn off auto updates.

You're right in everything that you said. However when we deplete the battery, we never deplete it 100%

What you see on your phone is the useable %

Someone correct me if I'm wrong on this matter?

If you ran your battery dry, you probably would only get 5 uses out of it.
