Easiest on the battery? I love sky raider and that's what I'm using. I've restarted my phone fully charged 4 hours ago and now I'm down to 15% battery life. I'm very disturbed by this. I made a few phone calls, surfed the market, searched the web for phone listings, used my tapatalk, and took a few photos, but goleee!! 15% after 4 hours?! Sheesh! I tried recalibrating my battery updating the kernel, (runing kingx2). I'm seeing on youtube and here on the forums about people boasting about their improved battery life but I just can't seem to keep up. As I'm typing I've bumped down to 12%. This is ridiculous. Any suggestions?

Uhmm. Well, the ROM has almost no affect on battery life. Battery is mostly used by Radio and kernels.
You need to give us more information.
Are you Over Clocking/Under Clocking?
What Radio do you have installed?
Are you using an Auto-killer?
Have you ever tried to bump charge your phone?
Did you clear your battery stats after a full charge, then reboot?
I think its kind a funny you even have to bump charge in the first place. I still am amazed that my Droid 1 gets 20 hours+ of battery life and my Droid Incredible is lucky to get 6 hours.
I am on UD 8.0 right now trying it out as Skyraider destroyed my battery.
Do you have to bump charge every time or just once?
Does reseting your battery stats fix anything?
What ROM + Kernal would you recommend for good battery life?
I am on radio 2.15 no auto killer.

I do clear battery stats after full charge then reboot.
I do power down the phone to get that additional charge it makes a slight difference.
I have the slightest idea what bump charging is. School me brother.
And btw, my battery life just went down 8% while typing this message.

Is that the BFS #2? If so, I'm at a bit of a loss, but it's worth mentioning that overclocking is pretty harsh on the battery. I underclock.
From my experience the rom does have an effect on battery.... there are many things in the rom and how it's setup that do in fact effect the battery usage.
With that said, stay away from cut, copy and paste roms like UD.... pure trash.
I'm getting about 10-16 hours from my inc with minimal usage. Running froyo 2.2 latest leak with the latest radio.

That is your problem right there. Aggressive auto killer? Jesus every time you do anything with your phone, whether it be starting a new app, sycning your gmail, or even turning your phone off, your CPU is going full blast overclocked killing every possible app and service. This will drain your battery. I bet it is the main cause. I bet that your task killer is killing an app or service, the app is restarting itself, and it kills it again... therefore draining all your battery.
But then again... if this didnt happen before, then i dont know. I still think task killers should be used very minimally only when your phone is running really sluggish and you know you have several apps running that you do not need.
The Rom has minimal effect on battery same goes for autokiller. Apps kill you battery, change governor in setcpu to conservative. Create a profile for screen off CPU min/max 245. Check your sync settings I bet something is syncing often or stuck in a continuous sync.

Since I've been letting it sit, cell standby has taken over along with phone idle. Prior to that, my phone was running pretty hot. I deleted batterystats from root explorer a few hours ago so I'm letting it drain again. Plus now I'm using my eris battery which has ran alot of cycles of drain & recharge. I'll bump down my task killer tho.
Sent from my ADR6300 using Tapatalk
As has been said, the absolute best way to make it through the day is set a profile for 245 when your screen is off. I underclock using hydrakernel 1 at 652 full time. I never need to use the maximum 1152 for anything practical.
The other suggestion is going with the seidio 3500mah battery. Sure you'll have a heavier bulkier phone, but people have gone upwards of 5-7 days on a charge. And also people state that it feels better in their hands. There is also a 1750mah battery that won't require an extension, and an official HTC battery at 2150 (but also requires an extension).
I honestly think HTC and Verizon screwed the pooch on the battery issue. I'm sure they were thinking extra sales on extra batteries, but at the cost of customer satisfaction.

Several of the more knowledgeable devs has said deleting your battery stats is useless, maybe even counterproductive. There was a thread in general about battery stats that several devs chimed in on.

Are you using task killer or autokiller? If you are using task killer get rid of it. Also Android system using your battery means its not sleeping right something is keeping your phone awake. It shouldn't be hot when screen is off.
I have a similar set up. King3 @1113 and skyraider3 I get about 10 hours of heavy use. I turned every sync down to once a day except weather @ 3 hours. The conservative governor and screen off profile with max/min 245 governor powersave. Will make a huge difference.
sent from my Incredible via skyraider & tapatalk
Yes that's awesome. Before reading your post I figured I should do a sleep profile. I turned off my syncing except weather. And battery life is slightly improved. I still have auto killer though. I set it to moderate. In at
29% and I been running it since 130. But not bad after watching a video and listening to a few songs and going back and fourth with a few folks on sms &a few phone calls. So should I still get rid of auto killer?
Sent from my ADR6300 using Tapatalk
I like autokiller. It's a min free utility. It should have no negative effect on battery. All it does is tweak the OS to be a little more aggressive on killing tasks as needed.
Also note that streaming especially over 3g is going to drain your batt. Videos will also drain it pretty fast.

Tasks fall into two categories: running and idle. Most tasks on the system are idle and are not using any battery. The tasks killing your battery are the running ones.
Examples of running tasks are;
Android system
HTC Sense
Any active widgets (clock, weather)
Any auto-sync (news, weather, facebook, twitter, etc.)
AND autokiller
Autokiller is constantly running looking for tasks to kill, using up the presious battery you're trying to save. Plus if it kills an idle task that you're going to need later the system just has to go thru the overhead of restating the app.
To confirm whether or not autokiller is using system resources, get app Android System Info from the market. Run it. Switch to the task tab, then hit menu and change the sort to CPU. You can see which tasks are active and using CPU/battery.

Yes when you look at cpu usage the Android System Info app does use the most cpu. But this is only because it's running in the foreground at that moment. Once you exit the app it doesn't run continuously in the background like autokiller does.
Did you determine how much cpu was being used by autokiller?

I have been reading of a lot of threads about how to save battery life..
here's what I done:
1. gps off
2. auto kill w/ advanced task killer
3. screen brightness at low
4. sleep screen after 15 seconds
I have got my desire for a few months and battery life has been bugging me. I understand that modern big touchscreen will drain the battery as compared to normal phones. Using a custom rooted rom atm.
I unplugged the phone at 12:00 with data on (push, auto-sync, etc), when i woke up at 7:00, I'm getting 73% of battery life. Charged it to full again and unplugged it at 8:30. My phone the phone shutdown by itself at 21:30. It's a little bit more than 13 hours of battery.
Is it me or everyone else is getting the same number? I just installed setcpu and see how it goes.. please tell me if there's any other way to preserve more battery!
I think it partly depends on which ROM you are using. I am currently using a new ROM (which I LOVE) but I've noticed that my battery life has decreased quite a bit. It can be kind of a trade off. I love the ROM so much that I'm not going to change it but it works ok for me because most of the time, I am somewhere where I can charge my phone if necessary.
Just found this thread which might help. http://forum.xda-developers.com/showthread.php?t=755903&highlight=battery+usage I'm going to try it and see if it helps.

My battery life is also quite shocking, also lasts for approximatly 13 hours under normal use, but if it is in standby then I'd say it lasts for 20 hours.
under normal use:

occasional games
occasional call (like 1 in 10 hours)
1~2 messages
btw you can find display on time in 設定->關於手機->電池->喚醒時間

I'm not familiar with the app but I am with FB and such and their widgets. Any app/widget polling at high frequencies like per second or per minute produces a high additional average drain which cuts runtimes, especially standby efficiency. That includes monitoring apps.
Do you have the battery widget chosen in Extended Controls, or the auto-brightness?

I can't say because supposedly, mine is well above average. It depends critically on usage and setup, too. 24-42hours with 5-9h display on and WiFi/2G always on is quite the norm on mine. Put to sleep (standby), it doesn't drop 1% until 6-9 hours. There's many many threads every week about this now. And I have many updating widgets and auto syncs running, just nothing to do with social networking since I've completely deleted from my phone.

Sorta new to the forum.
Just got me a HTC Desire. Rooted running CM6.0.2
If i baby it, i get maybe 6am-2pm. Heavy use, its done before noon. Ouch
Standby is ok, i left it off the charger last night and I lost 25% over 10.5hrs.
Ive got 1 twitter app on a 5min refresh. Weather is on 1hr. Screeen is down around 15% brightness. setcpu is on 245min, 998max, scaling on demand an a screen off profile of 245.
I have no idea what more I can do to get more then half a day out of it without just not using it lol.
Im pretty new to Android and all this rooting/rom stuff so maybe Ive got something screwy. I also tried a second battery from a friend, no change.
set that friends widget to longer than 5 mins and the weather widget to every 3 or 6 hours. i bet you that will get you alot more time.
Made the switch but cant see it making that much of a change.
Any other suggestions?
I installed the new app yesterday. Its nice to have a options menu again, I set update to never so when I close the app I expected it to fully close but I am left with 3 apps running for Facebook. I left my phone unplugged last night when I went to sleep and my battery went down 12% whilst I slept. Normally only looses about 2-3% in this time. Only app has changed is Facebook so it must be this. Anyone else having this issue?

Same Herr! I only lost 10% but i think this depends ob Thema length offen my night (only 7 hours) and in Thema fact that i'm switching permenantly all my connections off
Sent from my Galaxy Nexus using XDA App
yes, somehow with the new update, if we press home, the total cpu time will continue going up and eat my battery a lot probably 5% idle per hr wifi sync on.
Then i decided to swipe it away in the multitasking menu, and it stops, battery back to my normal 0.5 - 1% idle per hr wifi on and sync on and whatsapp on. So u can try that. hope that helps.
Glad it's not just me. But I thought I would do some extra testing.
When I first got my Nexus, coming from a rooted CM'd Desire, I was amazed the battery went down only a few percent over night and I've been getting over a day of use with it easily even when using the phone frequently. After an average day I was on 30-45% battery. I even tested with Skype on wifi, then left it on 3G and I still got good battery.
The day after fb install, I barely got through the day. 12% is what I ended up on. I'll test for a few more days.
So I unplugged the phone at 7am in the morning,its almost 12 hours since.
My Usage was browsing 20 mins,facebook 10 mins, 5-10 texts, few apps installation,5-10 emails,5 min instagram,10 minutes of calls, 5-10 minutes reading pulse,GPS on for 5-10 minutes
And general other things using the screen to look up contacts etc.
These are the screenshots below.
Im running everything stock jellybean 4.1.1,stock rom,stock kernel. Its rooted and installed flash apk.
Now i would like to know is this really light Usage?
For this usage,is the battery life good or can it be made better?
Thank you for your time!
Check your location settings in Maps. It seems Google Now is using up the battery by using the "Update Location" feature on my phone.
Yep the location settings are all enabled.

I think the "Location" features in Google Now need some fine tuning. I believe Google Now requires that you have location updating turned on to work so I have opted to turn off Google Now to see if Google will make it more efficient in the future.
But does this constitute average battery life?

Maybe I've always had below average battery life, but if I'm on any rom and I get 12+ hours of it + around 3 hours of screen on time. I usually consider it average. But that's basically what I've got on any rom/kernel, even stock.
At least your Nexus has better battery life than mine!
I'm using stock JB JRO03C ROM with stock kernel + XXLF1 radio baseband and with 3 hours screen using will drain my Nexus's battery too quick...
I gonna buy extended battery for my GSM Nexus but it will not help really much, maybe I gonna test Jame Bond kernel for Jelly Bean if that gives better battery life to my Nexus..

Try reducing the display brightness, it's the biggest factor in battery-drainage for me.
The display is at quite a low level. Maybe I need to flash other Roms to get better battery life.
For example right now.
My phone has been unplugged for roughly 2 1/2 hours. And I'm down to 86% and the screen usage time is only 33 minutes.

That roughly translates to 17 1/2 hours with 3 1/2 hours screen on time. Which is pretty average depending on what apps you use.
Could you provide more details like what apps/widgets you have with what sync settings you're using, email accounts, weather, etc?
Also, what variant of the Nexus are you using? GSM? Verizon? And are you using the stock battery or an extended?

Facebook is notorious for battery drain. Check the settings in Facebook and make sure to "uncheck" the location setting. Also, try to switch a couple email accounts to do "hourly" checks instead of push (unless you absolutely need them to be push). Also, try reducing the sync intervals on apps like Pulse and Twitter.
Considering you're using the stock battery the battery life seems on par with the usage your phone is getting even when not using the screen. Push, sync, and apps that use a lot of data transfer (like Dropbox) use significant battery.
I noticed the "Maps" application is using up a good amount of battery in your screenshots which means it's probably updating your location quite a bit and/or you use Navigation. Either way, that eats battery life as well. A lot of apps use location so it would be best to check those settings as well.
Also, depending on when you're using "2G", it could mean it is taking longer to pull data which might lead to battery drain.

Same here...but yesterdays battery life was remarkable...over 7 hours on with over 4 hours of screen on time at full brightness.
I'm thinking Quick Glace setting enabled is the drainer.
Feature is much more sensitive on ATTs.
hmm maybe higher sleep CPU level on ATTs
Sprint GN2 has whats called wakeup lag. When you wake device display has good 2-3 sec delay before turning on.

yeah that's how it should be.
As my screen shot shows there is 7 deep sleep wakeup points.
7 emails received , 7 wakeups shown with 3 of them being way to active.
Now the question is why.
Maybe a 3rd party app kicks in gear when email received.
Only thing I have on board is Fancy Widget with auto update disabled during that time frame

Seems reasonable to me.

I'm getting similiar to this. Tested 2 nights now and in 10 hours I'm dropping 2%. Multiple emails syncing, weather, Google Talk connected. Great usage battery life too.
In the "screen on" screenshot, live wallpaper active, 4 hours of Bluetooth music, brightness 80%, Web browsing and gaming heavy with 40ish minutes of phone calls and 30 minutes of GPS navigation. I hit 6h screen on time and 24h 32min unplugged when the battery finally died. That is stellar.
Also I'm in a LTE area, usually 4 bars signal strength but throughout my day I do leave LTE coverage multiple times. (I travel a lot)

Not sure if this applies to anyone else but last night I removed several Bloat apps before going to bed. I did NOT restart the phone. From doing this caused my phone to not sleep the whole night. Woke up this morning and restarted the phone. Phone went right to sleep after doing this.

I'm getting 1% drain a hour which is better then my note 1s 3%. Anyone using juice defender? Seems like battery life will be so much better then my note 1, I haven't both red to install it yet

Ok second day of sleep testing.
This time my toy is running Modded N7105ZHALJ4 MultiWindow rom with no 3rd party app installed.
Google sync active with 1 email received during sleep period.
Accuweather widget at 3 hour update interval .
Wifi enabled.
I'm still getting the 1% drain but this time only 1 email was received during 7hr sleep period so I can rule that out as being cause.
What the heck is waking up device lol
The AWAKE activity shown in screen shot should not be happening.
Edit
That small period showing Screen On I checked email device was awake maybe 90 seconds.
But from that point as you can see lots of activity happening that shouldnt
Maybe the small awake times are to check email, check weather, update Google now, Facebook, basically anything that is a widget or has check intervals for updates.

nah only thing running in background is Gmail & accuweather.
Gmail remains silent lights up sleep on push , seeing only one email was received that can be ruled out as problem.
Accuweather at 3 hour update interval so we can rule that out as well.
On Sprint version I had all kinds of background apps running during sleep , 15 emails receved and would lose 3-4% in 9 hour sleep session so somethings not playing well on ATT version.
I stopped by ATT store today ran across GN2 owner thats having same sleep issue like many in this thread
Turn on airplane mode and test it. 3g/H+ will cause it.

Its been sleeping wifi enabled during testing.
Tonight I'm going to test with network.
What's keeping my device awake? What wakes it up to begin with?
BetterBatteryStats.
Search for it on XDA and you'll find that XDA members get a free version. While it won't give you better battery usage, it will tell you WHY your battery is being used by something else.

Better battery stats is a great program, highly recommended from me too.
Not sure what the sleep problem is. I've maintained the 2ish% drop in 10ish hours of sleep. Great battery life still. Do you have NFC or Sbeam turned on? They have been known to sometimes cause battery drain and not show up as "awake" when looking at battery stats. Try toggling them in settings even if they are off and see if that makes any impact.
