Battery life with froyo.

Aren't we supposed to have better battery life especially since the JIT compiler is on 2.2? My slide ever since I rooted it seems to get pretty bad battery life using around like 8 hours using it all day for email and ****. But when I had the espresso sense stock ROM I could easily get 14 hours of battery life on the same usage.
Just wondering maybe some mem suckers or something? I'm not using live wallpapers either and I stay on wifi pretty much at my house all day.
I'm on the latest CM6 nightly.
Sent from my Mytouch Slide with Cyanogen's latest mod.

Boot into clockwork recovery. Hit advanced, wipe battery stats, reboot.

I've been using the 806 kernel (thanks dumfuq) with roman's 1.8 ROM and honestly, if you load up the latest SetCPU (I didn't use it much previously), it does the work for you.
I set up 3 main profiles and a couple others. Basically, I wanted whenever my Battery was < 100% to run at max/min 806/600 conservative(but i change this time to time), then Batter was < 15% m/m 600/400 powersave, but the profile the rules all will be whenever my Screen Off m/m 245/245. Now that can be a pain for letting your phone go while it does stuff because it does run a lot slower then while it's off, but honestly this does the trick completely, I've had freakin sick battery life.

Thanks for the replies. See its not too bad its just significantly lower than the slides ota update stock. But I am runing set cpu and that seems to help out alot. Post me your exact profiles and ill try them out. Also I did wipe battery stats and **** when I first flashed everything over but thats been like 4 nightlies ago. Ill do it again tonight when its dead and then recharge it all night.

In order, here's how I liked mine (but again, itll vary on your usage and junk..)
Type=Screen Off, min/max=245/245, priority=100, gov=powersave
Type=Charging USB/Full, min/max=806/600, priority=95, gov=ondemand
Type=Charging/Full, min/max=806/600, priority=90, gov=performance
Type=Battery<15%, min/max=400/400, priority=75, gov=powersave
Type=Battery<100%, min/max=806/600, priority=70, gov=conservative
Obviously, I'm still working and adjusting but for now this is how Ive been running and really had some great bat life. I may change the governor at any given point for perf. purposes, but usually this is what Ive had it at for a few days. If you have any questions feel free to PM me and I can help you out a lil more too man.

Thanks
TJD319 i gotta say thanks also for those profiles, I made a CM6 youtube vid for slide thats uploading and i want you to know i gave you full credit for the profiles that i use. they really are a big help, so i want you to know that.

I also would like to say thanks, with your profiles TJD319 my phone has been running mightly fine, no problems!
Remix, cool video, would be a nice refrence for people looking into overclocking/flashing cm6.

I'd also like to thank you for the profiles. I set them up yesterday and as of right now (on #TeamFenix 1.8 with the recommended kernel... not 806), I've had it unplugged for 27 hours and I'm at 38% battery left.
Thank you!

OverClock App?
I'm using CM6. Which app are you using for overclocking?

Only the best one out there, called Setcpu. Dont use any of those other ones, setcpu is in its own league.

I downloaded and set up SetCPU for only the screen off @ 245, and wow that alone has helped battery life immensely.

What does that do and how does it affect battery life?

I am yet another VERY satisfied Setcpu customer. Major improvements on an OC'd rom. The cool thing about Michael Huang is he posts the app free here on XDA. Seek and ye shall find.

I'm thinking about going back to the 806 kernel. When using that on CM6 with SetCPU I got up to 4 days with regular use. Now it's 2/2.5 with the 844. I suppose it's a drawback for wanting to play Final Fantasy 7 smoothly.

You guys need to understand the profile settings to realize what you're doing with them.
Powersave: always runs at the minimum you set.
Performance: always runs at the maximum you set (mainly used for benchmarking).
Ondemand: starts at your min, and clocks up according to how much cpu it needs. For ex. if I have it set at 400/806 ondemand, it stays at 400, goes up to 600 if it needs too, and then goes up to 806 if it needs to.
Conservative: same as ondemand, but tries to stay lower if possible.

In the off chance your battery has been improperly calibrated, this will give you the chance to recalibrate. This goes for all android devices. I have had to do it once so far with my slide. The battery wouldn't last longer then 8 hours. Wiped the stats, recalibrated, and voila.

Thanks, I got this info from another thread on here, so I will give it a try ... if I can convince the wife to stop charging the damn thing before it dies ...

let your phone die. turn it back on, run it until it dies again. keep trying to turn it on til it dies and worn't turn back on. Then plug it in, still powered off, and let it charge til the light turns green (should take 3-6hrs, patience...). Boot phone, still plugged in, and let LED turn green again. Reboot into recovery. Wipe battery stats and dalvik cache. reboot. let your phone settle for about 20 minutes before unplugging it. this should calibrate your battery.

Using CM7? You must read this! (Correct post)

Ok guys. I have to admit, I was about to give up on CM7 due to battery issues and what seemed to be memory leaks progressively making my phone lag more and more throughout the day. I have found something some of you may not be aware of and I wanted to share this amazingly helpful kernel with you.
Using x99, Scary, and stock kernels regardless of governor I seemed to maybe get 8 hours of battery life with moderate to heavy use. I am proud to say, using bcnice20's kernel I have had my phone on for 9 hours with 60% battery life today. This is incredible, even with lighter use on the other kernels I had NOWHERE near this amount of battery left.
Most of you may not have seen this kernel because it isn't posted. (as far as im aware) Let me help you out. First, go into your Market and download Kernel Manager. There is a lite version in there that is free. If you have an extra buck or two donate to the developer for making a neat app where you can download kernels in a convenient place by downloading the pro version.
What you will be downloading is called bcblend SIO tinyRCU kernel. I have not tried VR tinyRCU kernel yet. Not sure what the differences are, if someone could elaborate that'd be appreciated.
Regardless, I find the sweet spot for this to be at 245MHz min and 1GHz max on Interactive governor to work really well. The phone does not seem to get laggier throughout the day and consistently performs well, snappy, and just way better than the other kernels. (No offense to x99 and Scary, I appreciate all you've done!)
Give it a try and let me know if you all have similar results! I have heard that AOSP gets less battery than Sense ROMs from people on this very forum, and this may be the kernel to put that little debate to rest.
Oh, and be sure you have the latest CM7. I am on 7.0.2.1 trying this out.

Thanks ima try this out

I owe it to you for having me download kernel manager.

Well with CM7 and the x99 kernal seems to give me the best battery life with the SMARTASS governor. About 20 hours with medium to heavy use.

There is no link at this point, you have to do it via kernel manager. I'd upload it but I don't want to without bc's permission.

I haven't use any other "controllers" other than the one built into cm7... can I use that or is there a prefered one to change governers and such. Thanks!

Since CM7 lets you change governors right in its settings I uninstalled SetCPU for now, in theory I would think it would cause more battery drain but I don't know for sure. But yes I just changed it right in CM7. I changed the governor to interactive and set the max cpu frequency to 1036MHz.

Gonna try this out. I love CM7 but the battery is killing me. I pray this works.

Android system & cell standby seem to be the battery use culprit. I will give this a try though but don't really think its in the kernel. Ill report back...
Sent from my PG06100 using XDA App

This kernel seems to be really good about not sucking the battery while on standby for me, that seems to be the crown jewel of it all. Right Now I am at 14 hours off the charger with 29% left.. remember I was lucky to get 8 hours most days before using this kernel.

This is off-topic, but along the same lines: which kernels gave the best battery life for Sense?

Honestly I didn't get much difference between x99 and bcnice20's 1.5GHz kernel so either of those two. Scarykernel SUV works well on Sense if your phone can boot it too.

It seems to be true. I'm def getting better battery life. I also calibrated my battery but I've done that before without any major change. So far I have 5 hours of quite a bit of use and I'm at 71% I would normally be around 55-60% by now. I wonder what the main difference is with the kernel...

I have been using the x99 kernal and i have about 1 d and 12 hrs with about 45 % left.. I also have the calibrator apk from the market so it wipes the battery stat when im at 100%. and various other apps that deal with the speed of the sd card and what nots. So, me coming from the Hero is very happy with this phone...

[Q] noob with atrix on alien4

Hello, i just bought an atrix on ebay with alien4 and was wondering if i should stay with this rom or not? I have no mod experience on this phone. I would like to get better battery life and get rid of blur if possible. It might just have a weak battery, but it goes down fast when im not even using it. I believe it is unlocked bootloader. I dont want to go crazy, just like a nice setup thats fast and good on battery life. Thanks!!

Try the current rom out for a while, and then give CM7 a shot...
Sent from my GT-I9000 using xda premium

There are a few different choices. Definitely get comfortable first with flashing ROMs. Use the guides here in the forum to teach yourself how to do it. After reading the guides, read them again. You do not want to end up bricking your phone.
A few I myself have tried are CM7, HomeBase and Aura. I use HomeBase as my daily driver. My battery life has been pretty good. I usually get around 36 hours with pretty heavy usage of streaming music and videos.

I would give HomeBase a spin, but just remember that the de-blurred Moto ROM's do have certain things missing just have to read about whats there and see if you can live without it. I personally use HomeBase 2 which is slightly de-blurred and it looks and feels like a vanilla ROM. Some blur is good. Definitely read through a few posts and guides in the Development section to get a handle of whats going on and then start trying things out. I don't know what recovery you have but I would suggest first going to this link and learn a little:
http://forum.xda-developers.com/wiki/index.php?title=Motorola_Atrix_4G
Then going to this link to get the latest recovery (it will save you some headaches):
http://forum.xda-developers.com/showthread.php?t=1204500
As for the battery thing, try calibrating. If that doesn't work, it could need a battery with it being a used phone.

I tried Homebase and Aura a couple days ago, and I went back to Alien#4. Couldn't put my finger on why I didn't like them. But you should try all the ROMs you think you might like and see what works best for you.
I get really good battery with light-medium use, and my phone is very smooth. So if it helps, here's my setup:
Alien#4
Faux's OC Kernel 2.0 (to 1.3GHz)
Undervolted (75, 75, 75, 75, 100, 100, 100)
SetCPU "Screen Off" Profile to clock down to 456000Max
The biggest battery killer by far with that setup is the screen. There's a mod in the development forums that can lower the brightness much more than the stock minimum, but I haven't bothered with it. I only use my phone in quick bursts most of the time; check an email, send a text, etc. so it's not that big a problem for me. I can go couple days without needing a charge.

How to get a good battery life!

Well I don't no where to start really as I know I will get told off for making a new thread about battery life!
But this is hopefully some help for people out there that are trying to get a decent ROM and kernel to improve your battery life, well mine has really improved since flashing my Samsung GS2 with Lite'ning ROM 6.1 and flashing the kernel with SpeedMOD T-40.
I have spent lots of hours reading forums about battery life, I think I have tried everything known to man about this phone, somethings worked well somethings didn't, I wanted to get a decent battery life with out sacrificing any features I love about my phone!
When I got into rooting, about 2 months ago I was a n00b, but I stuck to it and learnt a lot each day, it's not easy and you can't expect someone to tell you how to do it, you have to read up about it like everyone else!
But anyway back to why I've created a new thread, well after installing Lite'ning ROM 6.1 at the beginning of the week which I really like as it keeps the Samsung software, I've used TB Pro to freeze the Hubs as I don't use them, the battery life wasn't what I thought, in fact I think I got a better battery life with the stock rom unrooted
I did some researching and found that the kernel can make a difference to (I'm still learning) so after reading some forums I learnt that speedmod kernel worked well with Lite'ning ROM, as It was just the kernel that came with the ROM, ninphetamine 2.0.5, so I flashed the kernel last night with Odin and within minutes I was back up and running.
I then charged the phone 100% and then use a battery calibrator app to wipe battery stats, I then did a basic test which I previously did before, I went to sleep with a fully charged phone, I left everything on: WIFI, mobile data network and sync on set my alarm clock and went to sleep (p.s I checked a few websites so battery actually went down to 98%)
8 hours later I woke up checked my phone to see what % it was left one, previously on stock ROM with same set up my phone would be on 65% due to the Android OS bug running high! This time it was on 91%, so that's less than 1% drain an hour! Happy or what!
I know some people might not say this was a actual battery test but to me it is and I can see a big difference, funny thing is the AOS was showin 35% in batt stats, which is strange!
Now as I write this at 1pm my phone has been on for 14hrs and I'm still at 75%, yes I know the first 8 hrs was in standbye, but I've had a lot of notifications come through from G+ this morning and I'm pretty happy with what I have got set up now, without compromise as well!
I will upload a screen shot later if any wants to see when my battery stats when its down to 1% etc
I hope his helps some people out there, but I wanted to keep it simple for some as I was once a n00b (might still be)

Cool, I did try CM7 but it was a nightley, build 68 I think, if they had brought the stable version out a week earlier I would be on that now, but I hear there are still bugs?
At least with Lite'ning its completely stable plus I like the look of the neon blue effect
My battery is on 64% now, I think I can go 2 days with this now

I'm on CM 7.1 Stable now and now even after 2 days i still have almost 40% battery left out, though on stock i never got more then 1 days

I first rooted it with superoneclick and it downloaded odin and flashed some insecure kernel first and then rooted it
Then i just installed CM 7.1 with Rom Manager, not sure which kernel is it

if you are gonna try cm7 try the latest nightly build....thats pretty more stable than the "stable" version...i think build 83 is out today and that will have pretty much more bug fixes and i hope they can get that browser lag fixed and thats pretty done deal for me to switch over to that completely

I can't keep up with the nightleys plus when I tried build 68 I think it was, camera didn't work at all. Is the latest much better?
Also which Android version is it based on?

Happy!
So as promised here are screen shots of my phone running at 1%, I forgot to screen shot CPU spy as well (sorry) but I can say that with this set up I am really happy, as I cannot remember when with general use I have managed to get over a day with out charging my phone, iPhone 4 included!
If there is a better set up out there with a newer ROM I would be interested as this is based on 2.3.4 tho Google Talk video works so I'm happy

nightly there is a new one coming out today version 83...still few bugs they need to sort out but once that is done il be on there...that firmware is based on 2.3.7.
im using speedmod latest kernel..it does not support bln or bootlogo but i would sacrifice all that for a decent battery life which i am getting....so far 5 and half hours past and im down to 75% and 2hours screen on time....not bad i think

[ICS] We need your help... Battery life...

Since the beginning of Android one thing has always been an issue with some of the greatest ROMs.
........................Battery life.
Every day lives are drained away by the pleasures and features of such fantastic ROMs... and such things at time seem so hard to bare that we try to change the lives of our battery by going to a different ROM.
So now you have a chance to make a difference, nay, an opportunity to change the lives of many...
This thread is strictly for how to save Battery life. CM9/AOKP have amazing battery life by themselves (but yet can always be made better) But for those on MIUI (Not so great battery life) this will be really useful.
Understand that everyone's device is different and although you may get 15 hours off MIUI/AOKP/CM9 others may only get 4 from them.
Post what it is that helps you achieve maximum Battery life. You may be the one to solve the cure to wowhowdidmybatterylifedroptwentypercentinanhourosis.
Be sure to include:
1. ROM
2. Kernel
3. Tweaks that have been applied through ClockworkMod
4. Apps used to save life
5. What battery you use
6. How long your life lasts
7. Anything else that you think may help

Eclair
Just Eclair
Any Eclair
Shoot me......
But seriously, disabling 3g on ICS saves a ton of battery life.

Uhhh,,,on ANY ROM...but not a practical solution.
I think the OP is looking for more practical solutions where they are not disabling major features of the smartphone.

1. CM9, although i think aokp does better.
2. Samurai Kernel, although just about any other ICS kernel should help. The biggest thing that you can change between kernels is the Governor and I/O depending on these two will determine how the CPU runs and in effect will determine battery life. Conservative is just about the best for battery life. If you need slickness and not too worried about battery Ondemand. If you want the best of both worlds i Think Wheatly is a good compromise. Also I/O , Sio is "simple" but VR is flash based so it tends to be the best. Otherwise Noop/Deadline. Also voltage.. undervolting will help limit the amount of well voltage to the CPU. So the lower you can get it the better.
3. Dont have tweaks i apply through CWM but i Run the V6 Supercharger, 3G turbocharger(optional), and the Kick Ass Kernelizer from Zeppelin.
4. I cannot stress this enough, Apps that say they save battery... run... which uses RAM and Resources... meaning its running trying to save you battery, Using battery. Which is stupid... and useless.
5. I have two a 3500Mah and the stock 1.5 year old 1500mah.
6. Typically with 3 hours of display over a period of 15hours (1500 mah) and around 5 hours of display over a period of 22 hours (3500 mah). However this is on wifi, 3g would deduct these a pretty good amount if you have sucky speeds.

He needs to get over it... lol. The only thing that truly saves battery life is managing your connections. There is no magic bullet unfortunately.

PLEASE! Don't tell us to turn off data and never sync the phone. Obviously if you don't use the phone the battery will last forever. I need a phone that can do the following:
Receive emails and texts as they are sent. (I use exchange push)
Last 18 hours on a standard or 1800 mAh battery.
I can just barely make that with stock FC09, I'd love to run ICS but with either CM9 or AOKP I barely make 10 hours.

Why must people post unhelpful comments such as the one above? I don't understand the logic there...
anyways since this was aimed at miui I get pretty good battery life with it... (3.5 hours screen on time) nyan v5 ftw! No special features... uv a lot (won't list my settings cuz every phone is different) and no oc... used to use jd but, it saves more battery if you just switch things off manually... really though until I flashed nyan my battery life was atrocious, but now just about on par with the peoples rom (4.5 to 5 hours screen on time!) Oh yeah, all this with the stock battery...

On aokp with 1800 mAh i can do about 3Hours of screen on time and 15 Hours of battery life and my phone was awake 75% of the time.
Screenie was at 15%
This was stock Everything Except ROM haha

Think about if your screen was on while the device was awake..your time would be cut in half

Oh my good golly gosh.
I just realized the best battery life I ever got was on DK28.
So take that. Let's go Frankenstein.
1. CM9 KANG June 02 build.
2. Stock
3. Services for V6 and Search Key Remap
4. Ha!
5. Stock. Came with device...need new one.
6. Depends on use. But I usually get the estimated six hours consistently.
7. If you're going to use a task killer just use the built in one. Overclocking is bad, and in my experience so is undervolting. GTalk, official Facebook application(especially this. Even with notifications off it still is always going), G+, and more are always running and are a drain. No live wallpapers, and no widgets that require constant updating. As much black as possible. Don't use third-party batteries. Obviously turning off 3G, 4G, sync, and such will dramatically increase your battery life.
WAIT! Why am I writing this? There is a freaking optimization guide. Why does this exist? For ****s sake.

Running AOKP build 36, stock, FC09 modem 15 hours running takes me down to 50% batt hour of screen time, constant crappy wifi connection in an area with crappy cell signal sync for everything but email and g chat is every 2 hours (weather and all that). Big thing to save batt for me was turning down my screen brightness. I was also getting crappy battery life till i let this rom install run the battery down to 5% twice.

By no means was I saying never enable your 3g/4g.. but the fact remains that the single best way to conserve your battery life is to be smart about managing your connections. I.e. not leaving it on ALL day and to only turn sync on when your actually checking your e-mail.. be that through an app like juice defender or manually toggling. If that's not more helpful than what you posted (UV a lot and don't overclock??? Duh.) than my bad bro!

Something we can all get behind here... I remember I used to get 24+ hours on froyo w/o customs kernels. Le sigh..

-I don't use the supercharger, but I do apply the same oom ram mods. These help close unused apps when they exceed the applied limit. Based on my experience, it's kept apps under control.

-THIS +9000! An app that spends all of it's time stopping other apps is wasting just as much "battery." I maintain, Advanced Task Killer, with NO, I repeat NO AUTOKILL. Set a widget on your home page, tap it occasionally to make sure everything is closed. Same effect as the built in task manager, but one single convenient tap.

-These numbers are pretty much the same for me. I almost always average 3 hours display on the stock battery between games and internet. 5-6 hours on the 3500, but I'm pretty sure it's not reaaallly the 3500mah it claims to be... . I NEVER turn off wifi or 3G, but google autosync is off until I edit my contacts.

I don't turn off my connections at all and get great battery life... and seens how the op states don't say anything about disabling 3g or anything id say your comment was the least helpful on the thread... but at least you tried... don't get into a battle of witts with me, I'm afraid your unarmed...

Firstly, I'm not trying to get into a pissing match with you. Its pointless. Secondly, the op makes no mention whatsoever of connection status. Thirdly, while you might get decent battery life w/o doing it.. I guarantee you'd do better if you did. Straight facts.
Edit: I am armed. With a small slide out keyboard.

Please follow the format specified by the OP. List the 7 items. Bickering in this thread will not be tolerated.
Thank you for your cooperation

1. CM9
2.ShadowKernel (I find nyan colonel to be a little more draining) SIO, conservative
3. None
4.System Tuner Pro configured to UV, under clock to 400mhz on screen off, to close apps that don't automatically restart themselves, configure "auto-kill" so its not as aggressive with killing apps that just stay on, and a few sysctrl edits that I honestly don't think make a difference.
5.stock epic 1500 mAh, my sprint store wouldn't give me an sgsII battery
6. 12-18 hrs depending on use, though it has definitely drained quicker
7.be easy on data! (There kennyG) turn off wifi when your not near your networks, turn off mobile data, Bluetooth, and autosync when your not needing it. (Unless you absolutely need PUSH email for your job or whatever though honestly as far as my job goes if its important enough for me to need the message immediately they will simply dial my phone number. Yeah I'm old fashioned.

- Cm9
- Shadow kernel
- No tweaks
-1800 D710 battery
- I get 15-20 hours depending on how much music I stream during the day.
- I got the biggest boost by using the profiles in CM9 to optimize my connections and syncing depending on where I'm at during the day. I have Wifi at work and home, so I have it toggle my data off during that time period and vice versa when I'm mobile.

Using AOKP with shadow kernel.
Best thing I did to help with battery life was to turn off all notification options in the FB app. And I set haxsync to download photos only when plugged in.
