battery drain tips?

When I run the latest android build on my Tilt 2, it flies through battery like no other.
Are there any settings I can tweak to get at least a full day's worth of use out of it (mostly in standby anyways)?
Thanks
Regards
Smith

I'd love to hear anyone's tips as well. As mentioned here:
http://forum.xda-developers.com/showpost.php?p=7959929&postcount=7622
Setting the sleep mode = 1 doesn't seem to work for me. The processor seemingly goes to sleep and enters a coma (yes, I set the clock speed back to stock in the startup.txt).
One quick tip to the OP is set the clock speed to stock.
Edit: sleep mode = 0 seems to work (GSM phone here). However, deleting the "acpuclock.oc_freq_khz=XXX" line from the startup.txt and setting sleep=1 just might work as well.
Edit2: sleep mode = 0 seems to result in the phone functionality breaking. It stopped waking up to phone calls after a while, and calling out wouldn't work either. Damn.. Just a heads up.

1. Close every program that you don't use on startup of android. You can do this with advanced task killer.
2. Run stock speeds.
3. Turn down the screen brightness.
4. Make sure your phone goes to sleep when you are not using it (green led = sleep)

Is advanced task killer installed by default?
Also, how can I clock it to stock? I wasn't aware that it was overclocked past stock.
Screen brightness makes sense, I'll definitely do that.
So, if green is sleep, what is the orange?
Thanks

I reckon hepatic feedback would drain a little battery on its own probably best to turn that off

This is all true. I'll have to do that.
Still figuring it all out. Once I can get a solid 18-24 hour charge cycle out of it, Android will become my primary OS, easily. Simply works better, IMO

For me sometimes it's green, sometimes it's Orange - not sure how to change it back green -
I use Advance Task Killer, but then i also read that Froyo 2.2 doesn't need a task killer?
The two things that have helped battery life the most were:
-Switching to stock clock speed (the reference over the overclocked BLZN which i loved but killed the battery life)
-turning off background processes... i only turn it on when i have to (using the market, etc)
I would love to hear more tips

The colours are not that hard.
Red/orange = awake
Green = sleeping
If the LED stays red, then your device is doing something, you can either wait or try closing the programs with the task killer. That will help sometimes.
For returning to stock speeds read the faq And advanced task killer can be downloaded in the market.

Thank you guys all so much, big, big help to me!
Android is definitely going to be my full time OS shortly

Its kind of tough trying to go anywhere without a charger nearby. The battery drains quickly and on top of that the actual battery meter is off.
So sometimes that is a main issue

Indeed but that is something that they are working on it as we speak. Give them time

I ran a test last night before going to sleep to see how long the phone lasts.
Charged my phone fully. Ran advanced task killer and killed all the programs. Put the phone in deep sleep ( green light).
Woke up 7 hours later and phone was completely dead. I do have auto sync turned on, but only over wifi, so it should not have used any data as i have the data turned off and no widgets on my home screens that auto-update.
I'll try again tonight for a shorter time (5 hours).
Running the blazn aug 30th build.

How did you 'put the phone in a deep sleep'

I turned off all auto updates.
The next day i did the test again, charged the phone to 100% and used the phone moderately for 8 hours before the battery died.
Without overclocking i can safely say i can get the phone to last 8 hours with moderate to heavy usage, which is excellent.

My main problem with the new updates are that it constantly restarts or crashes after using it for less than 30 minutes while before I could use it for several hours. Not sure whether it's to do with battery life or not as when it boots back in WM the battery is near full.
The biggest things that have helped conserve battery life for me are disabling GPS and background syncing but some apps require this to be enabled. :S

Phone seems to recover from "sleep"
FWIW, I set sleep mode = 1 and removed the overclock line from the startup.txt and the phone SEEMS to sleep and "wake up" just fine. Previously, I had problems with the phone going to sleep and when waking up, everything seemed fine, but the phone didn't work. With the overclock line removed, it seems to "wake up" with the phone working now.
Just a heads up to anyone who wants to save battery life.. might want to remove the overclocking line in the startup.txt..

[Q] Questions about CyanogenMod, and general battery life

Hey everyone, last weekend I unrooted and wiped my phone, went back to factory settings, rerooted and installed CM6.1 RC2. I've been enjoying it so far (because I hate Sense UI) but I've got a couple of questions that need answered. Hopefully you all can help me.
CM6
1. Is there a setting to turn off always-on mobile data? I cannot find it.
2. For some odd reason, I cannot turn on bluetooth. I've not had a problem with turning on bluetooth with any other rom. In fact, I remember testing bluetooth the night I installed CM6. Is this an issue with the phone or the rom?
3. No matter how much I turn off Auto-Sync, it turns back on. What is doing this?
Battery Life
1. On average, I get around 10-14 hours battery life a day, maybe a little more if I barely use my phone all day. I've heard a lot of people say that an ideal battery drain with the screen off should be 1-2%/hour, but mine will drain from 6% to even 10% in 40-50 minutes (EDIT: Currently 75% battery left, unplugged for 2hrs 30min, done nothing but use the browser for 5 minutes, download something, and install it)! I use systempanel and spareparts to monitor which apps could possibly be doing this, but none look like they're eating up too much of the battery. I check Facebook 4-5 times a day, use the browser, and check Gmail. I don't use Google Talk. My screen brightness is around 30-40% and I have underclocked when the screen is off with setcpu. What is draining my battery so fast? It's a shame that there are so many cool things to do with this phone but I can't do them in fear of my battery dying before the end of the day
Sorry, that last question was long, but I did not want 2 separate posts. Thanks guys, I hope you can help!

1. no. you could however turn data roaming off or use a program to accomplish this such as "tasker"
2. what do you mean you cant turn it on? what does it do when you enable it? use the widget in your notification drop down.
3. turn off background data as well and that should fix your problem.
and as for you other question. 10-14hrs is perfectly normal for battery life on cm6.1. and fyi: its RC1. there is no RC2 for 6.1 as of yet

Ah thanks for correcting my mistake, and answering my questions. My battery life isn't terrible per se, but I guess I was asking more on how I could make it better (and if I had a rogue app/other battery eater), especially because I see people claiming anywhere from 20-40 hours with a few tweaks.
And regarding the bluetooth issue, it just won't turn on. The option grays out for a few seconds like it usually does when it's initializing, and then it doesn't turn on. The notification widget method does not work either.
Also, there's no other way to turn off auto-sync? I just think it would be a hassle having to turn background data back on everytime I want to use the market. I use JuiceDefender, too, could there possibly be a conflict between the app and my phone's settings?

Man i'm with you here, I use CM6.1 too and love it but the first 30 minutes i unplug the phone from charging i'm already at like 90% battery =/

I had the same problem with my Bluetooth recently. When I try to search for devices the phone locks up and I have to pull the battery. Wonder if this is a kernel issue. I am on snap

Yep, I'm on Snap too; must be it.

Another thing; I've got a friend on Stock 2.2 Sense (battery sucking widgets filling the home screen, etc) with 100% brightness and mobile data constantly on and he gets better battery life than me (20+ hours!) What is going on!?!?!

I couldn't believe it either, he had 3G on all day and everything and we barely get any signal at all in class. On for almost 8hrs with more than 70% left. I was at about 53%

[Q] brightnes with notification bar doesn't work anymore

Hi
Finding, that the battery from the SGW drops to fast, I installed an so called battery saver app. Firstly I tried juice defender, finding out that I need Pro version to really save energy the way I want to -> deinstalled. Next I tried GreenPower free battery saver. Didn't notice, that switching off WLAN and G3/4 is also only available in pro version. Nevertheless I configured everything in order to give it a try.
Today I noticed, that GreenPower... switched on WLAN and GPS and Blutooth and every other power consuming device. Despite disply brightnes. For what?? So I uninstalled the app.
The problem now is, that GreenPower... switched the display brightness to automatic! Even at the widget "Energiesparmodus" ("powersavings"?) the sign for brightness shows an "A" for automatic. I can adjust the brightness at settings (1000 subfolders) BUT the quick cool sliding at the notification bar is not working any more.
Is there a possibility to switch it on again?
I'm rooted and have Titanium Backup installed with an full backup from last week.
Trying to recover notification bar did not work (screen notification "backup failed" and notification bar was gone; after reboot bar back again, with no brightness regulation).
Anybody with glue for this?
holydiver

Personally recommend to not use a battery saver apps or some sort eg. when the screen is off data connection will be off.
And when you wake the SGW it will again struggle to look for the data connection signal ...that will take energy away from the battery.

What about installing a custom rom like Bionic cow? Had the same problem with the energy on this device with the stock rom and i tried different "saver"-apps.
At least i gave this rom a try et voilà even with intensive use the accu lasts much longer than before. I can't say why this rom reduces the energy consumption, maybe because of the lightweight launcer and some other modifications...

solved
Thanks guys!
It stopped working for 3 days. On the 4th suddenly it worked again. Without doing NOTHING. I even didn't do another reset. curios

[Q] Motion Launch is draining the battery

I've had this phone for almost 3 weeks now and I have been experiencing battery drainage when on standby. My battery would start off at 100% when I unplug it from the charger, and without using at all after half an hour I'd find it at 93 - 95%. So I installed a battery monitor (GSam Battery Monitor) and after a week I found that there were 2 things consuming most of the battery, the screen and multiple apps. So I decided to do a factory reset and test out the phone with the apps that came with the phone. The battery life improved slightly but it was still too much. I decided to check out the display, at first I thought it might be the brightness but then I remembered that motion launch also uses the screen (duh!). I turned it off today and so far I've only lost only 2% battery in 1 hour and 37 min, on standby. This is good and all but I really like motion launch, it's easier than reaching for the top of my phone when I'm using it with one-hand . My question is, does anyone have the same problem as I do? Cause if so it might be an issue with all the One (M8) phones running the software. If not, It might be my phone and I can send it to get fixed or something. Thanks

I don't have this issue.I have viper rom installed and motion launch all the time and I lose only 2% in 8 hours in standby.My screen on time is 7h30min.Try another rom or send it to change with another one.cheers

Motion launch isn't draining battery for me. I lose about 1-2 % when I leave it for the whole night

Motion launch shouldn't use much battery. Firstly the screen isn't always on waiting for touch input as you say. The touch response is only awakened when the phone sensors pick up movement. For this the HTC one uses a new device called a fusion sensor hub. This hub is a collection of sensors and is able to have active sensors that don't need the cpu and thus have a very low power requirement.
I'd look more into display options and turning the WiFi off when not needed and disabling some of the sync options.

I don't think that the battery draining has something with the motion launch to do. For example for me during the night on airplane mode, lose about 0,5% per hour.

Yeah I think my issue is with sync. I'll test it out for the week maybe something will change. Thanks

So I decided to try Wakelock Detector, I found something called "1013" keeping my phone almost 2 hours awake. I researched it and found no solutions to this problem just people reporting on the same issue with other devices. The app also showed me that my phone only gets 3 hours of deep sleep and it stays 8 hours awake. How can I fix this on a non-rooted device?
Edit: I found something that says that the 1013 is a partial wakelock and can be solved by a silencing touch sounds. Going to try it out and post the results here

App that keeps ambient mode always on?

So I found this one app " Swipify" that lets me keep the watch face on full time. I like it but it drains the battery a bit faster then I would like. Also when charging the watch the round charge progress bar does not advance so I have no idea how charged it is until I take it off the dock. So I un-installed it. I am looking for an app that will let me keep the watch in the dimmed "Ambient mode" full time and then when I lift the watch to look at it, have it to the full watch face mode until I set my arm back down.
Anyone make such a add-on app by chance? :fingers-crossed:
Or should I start learning how to code apps?
Any chance they (moto) will update with such features?
Thanks,
-DK

I'm not sure if such an app exists, but I'm just about 100% sure that Motorola will never add this feature. The current 5.1.1 software version was significantly delayed because they were trying to optimize battery life. I think it's a combination of a small battery and an old, power hungry processor that is the main problem.

I find that since upgrading to 5.1.1 I can go the entire day on one charge in ambient mode but I have to leave the watch sitting flat in order to test it. But by the end of the day I still have 25-25% charge left with it running the entire day in Ambient mode as long as I do not get to many notifications during the day which of course I can control those with no problem.

Huh? What's the point of having a watch if the only way you can get it to work is to lie it on the desk and not touch it, oh and to disable notifications, aka the only thing that makes the "watch" something more than juts a watch?

That is why I am looking for an App similar to Swipify to keep the ambient mode on full time. And I only let it lie flat for a day to test the battery life and it makes it through the day with the screen on full time in ambient mode. So I know the watch is capable of doing what I would want it to use it for.
And I said "as long as I don't get too many notifications", I never said I disabled notifications. I still have those on.

Gocha. No need to be defensive, sorry for the misunderstanding.
Still seems like you'd always be on the hairy edge of running out of battery in a real-world scenario. Hell, I'm ambient mode off but tilt-to-wake on, and some long days I barely make it to the end of the day. Never had luck with even the fake ambient mode the Moto provides.

All good, sorry to come off as defensive. :good::highfive:
Been using it with tilt-to-wake turned off and I am finding that by the end of the day I still have plenty of juice left.
With Ambient on and tilt-to wake off I find I have about 35-40% left at the end of a 7am - 11pm day. That is with receiving some email and text notifications (maybe 15-20) during the day.
I know everyone has different uses and ideas of how to use their Moto 360 so everyone's setting are going to be different, but what I am after is a always on "dimmed" or "ambient" mode with the option to turn on tilt to wake so I could test the battery life both ways. I would also like to use my 360 for home automation control and I I know with "Autowear" it is possible but from the little testing I have done so far it would kill my battery way to fast so perhaps on a future SW that will be something I will be doing.
Pausing and starting Netflix or HBOgo or Plex from my 360 is working pretty good for me as a start.
Think I will try and contact the owner of the Swipify app and see what he can do for me...... :laugh:

With the latest update LCA44B, when ambient is on and tilt is off, the screen will stay on all the time. However with ambient on and tilt on, it is same as previous behavior, screen will turn off when you put your arm by your side.
