Rooting doesn't effect battery life.

You went down 13% in 4 mins -________-. Go exchange your phone, lmao. Or turn off 3G, Accounts & Sync, turn off brightness, and install JuiceDefender. See if that makes a difference. My phone goes down 1% in about 2 hours...
mine barley lasts until evening when I plug it back in... but thats just how these phones are. 1% in 2 hours is very unlikely unless you just don't use it and have everything disabled.
Rooting your phone alone has no advert consequences on your phone's battery life. What you do on your phone does

So you go 200 hours between charging? I find it hard to believe that you only need to plug it in every 8 days.

indeed what a troll
Just turning off push email/notifications can have a significant effect on battery run time. I doubled my run time by putting some reasonable settings on my sync intervals.
I refresh my exchange account every 15 mins during peak-time ( 1 hour off-peak ), Tweetdeck every 2 hours, all other accounts hourly. With moderate use I have no problem going 24 hours on a single charge.
Also be on the lookout for misbehaving apps. I had a single dormant streaming app sitting in the background using over 10% of my battery. I kill that app manually after every use.

As it's being said before, if you do not use your device you get excellent battery life out of it - might as well have a painted brick on your desk.
Mine lasts a bit more than half a day, but I use mu phone a lot for streaming, texting, browsing, a game sometimes. I think it is about average, I wouldn't sweat it. Still beats my old.nexus one in battery life

My battery last about 24hrs on average. I bought extra batteries and I have run each of them until they hit 1% and then I use and external battery charger, bought of of ebay, came with 2 batteries and a charger for them for 14 bucks, and i do have certian things i do that drain more than others, but for instance i watch a 2 hour movie, and started with a fresh battery, (99%) and when the movie was over I was at 73%, much better than when i first got my phone, but i also still use advance task manager which everyone says is bad for the phone, but i just use it and exempt everything that is used for normal operations, then it only kills the apps i have used and want to kill. now the settings does allow you to do this by each app, but i am just lazy and paid for the app back on my G1 days and it makes killing them in widget form so one click. i just tried to exclude all the things that the phone uses to operate smoothly, and kill the rest of the garbage apps, also you can try a program autostarts, i have it as it suggested it in the app forum sticky, costs a buck, but i used it, not sure how much it helps, but like i said all I have done and how i use all of my battery each and every use now gives me outstanding battery life. No 8 days or anything but still tons better than my G1 and i didn't keep much running like i do on this one. Also turn off auto brightness, and just use the slide if you need to turn it up, dont use live wallpapers and turn it to use 2g only, and then when you need the 3g turn that back on, there is widgets to get for that so its a one click as 3g really drains the battery, so when not in use go to 2g if your not surfing the web or wacthing videos off a site, doing those things will help the life of your battery.

That just means that your while your phone was turned on, 74 percent of the total power was used by your display.
Makes sense because you turned your screen on for about 74% of the time.
Try running fix permissions from clockwork. I recently got a boost in power & battery life from doing eugenes v6 mod and the suggested lag.

Hey guys,
Just created this thread so we could all have our battery life info in once place and keep the dev thread from getting cluttered.
Please post the following info:
1. Standard or Fully Loaded version
2. Total hours unplugged and percentage
3. Details (percentage and time) for each service
4. And any pertinent details such as apps used (juice defender), or extended batterys
Also, please don't forget to calibrate, airplane bug fix, and kill that drm.
Ex. (will edit with final time)
1. Loaded
2. Total - 8h50m @66%
3.
Display - 55m 78%
Cell standby - 8h50m 9%
Wifi - 6h40m 7%
Phone idle - 7h54m 4%
Voice - 1m 3%
4. Juice defender, setcpu @ 100/1000
Ideally we want to wait for a full drain to post stats but this is just an example. Thx guys looking forward to seeing what you all are getting.
Just installed it will get back to you in a couple of days after recalibrating my battery.
Btw, i hear Juice defender does more harm than good...

Interesting. I think you are right, we are essentialy minimizing out idle drain to a certain extent. However, even activily using my phone it drans slower than stock with this rom. My next run ill try and use it all day to see what I get.

Battery drain
Hello everyone, noob here. I can't post in the development forum on this but it pertains to the battery and charge to a degree. Maybe someone here can help me in some sort of way.
I rooted and flashed the SyndicateROM Frozen yesterday, used it all day and never a hiccup. This thing is lightning fast and props to the dev's but here is the only issue I found. This morning after waking up I noticed the phone was stuck on the ACS android startup icon. I plugged in to charge last night and it's like it froze the phone when it reached full charge. Anyone else experience this?
Thanks for any help that I receive.

I think I read in the dev thread that it's a known problem with the kernel? Or maybe it was the rom... or CWM? anyways the dev's know about it. Just don't charge your phone when it's off.
Battery for me seems to be a lot better than stock, but I'm always charging here and there... today I'll let it run without charging for 4-5 hours and I'll report back. Using a lot of setCPU profiles.

Are you charging it with the power OFF? Lots of people were posting issues of freezing when charging with the battery off --- and I think the probs are related to CWM -- not the ROM. Only charge while the phone is on -- and you should not see problems.
I put on to charge with the power on last night because I had set the alarm to wake me up and it never did so that is when I noticed it. I don't think I've ever charged it with the power off, even when it was stock.
Maybe the dev's will come up with a fix sometime in the future. As for now, I'm happy as hell 'cause this ROM is great.

Did this just happen once? If it doesn't happen over and over, I wouldn't consider it a bug. I have only heard of issues like you describe with the power off.
I'm looking at 12 hours on ACS Frozen on average. I haven't even gotten close to the rumored 30 hours with "heavy use" I think my use has been moderate. My battery use log only only lists display 98% and cell standby 2%. This confuses me. I do more than sit there staring at my homescreen.

How you use your phone makes a difference and while 30h is possible, I don't see it happening with heavy use unless that is little display use. Below is my most recent "heavy use" run. Basically tried to use the phone all day, xda app, browsing, mainly wifi, 0% screen brightness.
1. Loaded
2. 8h7m @5%
3.
Display - 5h33m 95% <- serious display use which kills the phone quick
Wifi - 4h56m 2%
Cell standby - 8h7m 2%
Voice - 4m30s 2%
4. Setcpu @100/1000, juicedefender, 0% brightness
Pretty good considering the insane display usage. With normal use I get over 20h so that just shows how fast it kills your battery. Going to do an "extreme" run next to include heavy cpu use (play emulators all day haha).

You did that with a standard battery? I haven't seen anyone post more than 4 hours of display "time on". That's impressive. Maybe I should try 0% brightness. I have mine at 25%. Are you on "Conservative" on SetCPU?

The 98% means that 98% of your battery use is coming from the screen. Click on where is says 98% and look at see what the use details are (the "time on"). Generally, most people are getting less than 4 hours of display time on with a single charge. The explanation is that some people stretch 4 hours of display time over 30 hours of use. In other words, the people who are getting 30 hours of use only have their screen on 10 - 15% of the time (or less).

Yes, using the standard battery. Setcpu is on conservative. I always use 0% as it looks great (kick it up tp 25-50% outside). I think I was able to get that long of display use due to minimizing cpu usage and other services. All I did is browse in dolphin and use xda app. And, that was pretty much all on wifi. Only change was the hour I was at the dog park on 3g and I recorded a 5 min video.
I bet my gaming session tomorrow will kick it down to ~4 hours
With phone calls, texting, and music player, I average between 16-18hrs. If I start to web browse or watch videos then about 8-12hrs. Very impressed with this ROM to say the least.
1. Standard
2. 31 @ 5%
3. don't have that it was yesterday
4. standard battery, auto brightness, overclocked to 1.2, wifi on when I was at home and 3g at work.
I calibrated the day after froyo dropped. I didn't do the airplane thing and I thought drm was not in this rom. So in other words I didn't do any fancy stuff.
I will note today I tried 1ghz (which is undervolted) with 4G on all day (I have a repeter on my roof at work) and after 14.5 hours I am at 30% with about the same concistancy of usage as yesterday.
Edit: I only have 1 gmail syncing right now. We will see if I get these magical numbers when I put my other 2 gmail accounts and my 3 actice sync exchange accounts on Monday.

I'm getting mixed battery life. The first day on the rom/kernel I dropped down to 79% in 9 hours, with medium use (no web browsing). I was getting 1% drop every 1-2hrs, and thought it was amazing. Today I tried to be really conservative and didn't use it at all and it dropped 4-5% every hour WHILE IDLE.
Anyone else experiencing the same problem? It seems to happen after a reboot to be honest.
NOTE: If I disable data network mode, battery life is amazing,
I'm not sure about my battery life. I charge mine differently than the average person though. I charge it at work and leave it in my desk, because I use it a lot during my lunch break or whenever I get any downtime. When I get home it's usually at about 70%, and it remains unplugged until the next day. I used to have to charge it at home and at work.
Hi,
I am working with my eee pad for the last week and I am very disappointed from the battery results.
I sent to to the importer in my country and he claims that he checked the battery with the asus appropriate device and it is as good as new.
after nearly 5-6 hours it gets to a point that i need to charge it.
youtube and browsing.
this is my config:
Screen brightness is on auto.
WIFI off when screen off
I make sure with advanced task killer to shout other apps down(Hate that).
Screen goes off after 1 minute.
Is that normal? am i doing something wrong?
Thanks

I have found the following to help conserve battery charge :
1. Screen set to auto brightness
2. Sleep mode set to 1 minute
3. Wi-Fi off when in sleep mode
4. GPS set to off
5. Bluetooth set to off
Edit : Forgot to mention...I don't use "live wallpaper" which tends to be a battery power consumer

Actually I didn't turn off GPS when I was on 3.0. All other setting were turned off just like 3.0. On that first day (leaked verison) I noticed that the battery life got worst. Before I could get an hour per 10% when surfing and listening to music. Now I'm getting using about 17% per hour. Its 3.1, cause xoom owners r also complaining about it after 3.1
strange, i have amazing battery life.... i use a live wallpaper too.... decent amount of use nets me 2 days.... i CAN kill it in a day if i really try.
browsing, twitter, gaming, etc.
I don't know if this helps but not using the dock seems to improve battery life. I have been using the tablet without the dock for the last 3 hours playing Plants vs zombies and Bang bang racing and some flash videos online and battery is still at 82%

Tonight I did a factory reset hoping to see any improvement for the default browser as far as speed goes, but it was the same as before. After installing the 3.1 leaked on the 28th I noticed that the battery life got worst then before. After doing a factory reset tonight, my battery life has improvement! I was streaming a dvd from my server to the TF using Plex and I got 30 mins of playback with only eating up 5% of batter life! I used battery indicator pro to keep track of the usage. This is a big improvement prior to the factory reset. My brightness was set at 50% with auto bright disable.
For the next 30 mins I did my regular routine using playpro and surfing the net my tf only ate up 5% of battery life. This is the same kind battery life i was getting before on 3.0.

Its up to you. I noticed that I was getting better battery life before upgrading to 3.1. I don't regret doing the upgrade cause I will trade getting a working youtube app over better battery life. Like I said after I did a factory reset it looks like my battery life has improve on 3.1.

This is what happened tonight.
It charges normally from 17 to 39% and then slowed down and stops charging at 81%.
saturdaymorning i had something similar, but only then it stopped at 26%...
I can not charge it right now (or saturday) i have to wait an hour or so.
between saturday and now it charge normally to 100%

I can't comment on battery life, but did notice something a little alarming with regard to battery drain. Was on the couch for an hour talking to someone using viber, just plain text. No video or audio. Tablet was plugged into the wall, and after about an hour i noticed that the battery had gone from 100% to 98%. Should not be possible for a simple messaging app to cause the battery to drain faster than it can charge. screen was on auto brightness as well.

Did you look at your battery information to see what was using the most energy? Display is always far and away the highest for me, and if it was on Auto Brightness, depending on the lighting around you, it could have been running at full brightness...which would be a pretty massive drain on battery.

Once the device reaches a full charge it cuts off the power draw to avoid damaging the battery. It's normal for it to hover between 97% and 100% while still plugged in.
I barely get 6 hours of use now.

I did not look at battery usage, but the screen was generally dimmed, where as normally i have it manually set to full brightness, and nothing was running in the background that would not normally be running, that is to say nothing other than android stuff, it's basically a tablet for internet, email and skype/viber while i watch films etc on my computer

Indeed, but this has never happened before and i typically run the device with screen on maximum brightness. on 4.2.1 it would always show 100% when plugged in, i never once saw it drop to 99% or below.
So without further analysis of the issue, it could either be that something is sucking more power, which would seem odd, or that the update has brought about changes to the way the device charges, or changes to the way the device displays the battery level.
Damn guys, I don't know what I'm doing wrong, but I'm jumping around in happiness when I manage to get over 6 hours of screen time lol.
I've been on battery for the past 12+ hours with about 6 hours 15 minutes screen time and still have 36% battery left. Battery seems at least as good as on 4.2.1.

Thanks, I've done this now, and get about 5~6 hours of screen time now with around 50% left.
My battery life has gotten considerably better after updating to 4.2.2. The biggest improvement is how little the battery life drains on standby...it's nearly nonexistent.
Sent from my Nexus 10 using Tapatalk HD
Standby has always been great for me. With stock rooted 4.2.2 I'm getting great battery life. Loses maybe 2% after 8-10 hours idle. In constant use I'm averaging 11 hours on screen. I have everything on and synced but as I'm indoors I stick to 30% brightness. Also, I'm mostly just browsing. With games the life would be less for sure. Totally satisfied with the battery life of this tablet. If yours is getting truly bad battery life I suggest you try searching for rogue apps. After that, try a complete reflash of the stock image which deletes everything. Another thing I've found that helps performance is setting the WiFi band manually. As I have a pretty good router that utilizes both the 5 and 2.4ghz bands I set mine to 5ghz only. I live in a town house and 2.4ghz can be pretty congested even after turning my antenna power up to 150mv or greater. The 5ghz band is pretty open. I'm getting load times on webpages comparable to my i5 2500k sandy at 4.5ghz and ssd with its 5ghz WiFi n wireless card. This is the quickest rendering tablet I've ever used.
As an aside, the complete re image to stock 4.2.2 from Google might fix reboot problems as well. It seems to do wonders for people with battery and other issues on early n4s. My screen on mine is new but the hardware is from launch day.

Well...
Well, I haven't tried that, but I have heard that many people said the update can help save battery.
i just got the update i was barley able to hit 3 hours screen time lets see how this one lasts.

My battery life is significantly worse after the update. I flashed back to stock 4.2.2. It seems that the problem with mine is my tablet isn't sleeping. Android os is the highest battery user. Maps is taking a lot too. I have Google now and location services turned on so I'll try disabling those again... No rebooting though

if you are rooted change your processor speed to 1.5gHz, it really helped me get better battery life
so far at 6 hours of youtube with 50% left to go

do you mean reducing the maximum cpu clock to 1.5 ghz?
My battery life has been pretty good. However, the number one thing consistently using battery is "Android System". Is this normal? Thanks!
Same here. On all my other Android phones Screen is the top user.
U are using ips technology on the screen unlike amold that saamy used which kills the battery in hours in full brightness . As you could see that the iPhone has good batttery life because the 720p ips screen.

I've found that rebooting the phone after taking it off of charge, the battery life is awesome. There seem to be some wakelocks that kill the battery and for some reason, charging has something to do with it.
I don't know if this is why, but I heard the G2 has special screen technology that greatly reduces battery drain.

Those claiming that Android System > Screen for battery use on the G2...I'm coming from a Nexus 4 which is also IPS.

Yeah, somthing about 30% lower battery use or something like that. It's 6 hours since I took mine off the charger, must admit very moderate use, some toying, some photos, some mails and 1 phone call. but still, my phone is at 96% battery. My old S2 would be at 60% at this point.

What's your highest battery user?
I'm at 93% after 5 hours with only a dozen SMSes, an IMAP push account with a few emails, and 2 other pop accounts, very light use...Android System is 34%, Screen 21%.

I tried this and it worked. However, one instance is not proof I guess haha. I will experiment more tomorrow (namely, not rebooting after charging) and let you know what I find. I wonder what specifically about charging may cause wakelocks?
Over 48 hours of use, more than 50% battery left. 3,5 hours screen time. Android system worst offender with 35%, screen 2nd with 25%.

If you look at the programs listed under Android System, try uninstalling the ones that you would never use. This has seemed to help me. But to be honest it was kind of unnessary because the battery life is just crazy badass. In a few weeks or so when the devs have there way this phone is going to be epic.
It is two things, which by the way are great news.
A) LG's screen tech which doesn't refresh pixels when the images are static
and B) IPS
What we can't control is screen power consumption, but guess what? We can control android system consumption through kernels and roms. This means that we can *hopefully* expect EVEN BETTER! battery life since the screen is, for 80% of users, the main culprit for energy drain.
Just a quick note that flashing CleanROM on my ATT LG G2 basically took my battery life from <20% at the end of the workday to just under 80% at the end of the work day with increased use on the CleanROM install. Highly recommended.
Been off the charger since 6:50 this morning. Sitting here at work doing some texting, Words With Friends, and a test call for a co-worker...96% at 12:15pm. My Nexus would have been at 40% by now.
So is Android System different from Android OS?
I normally can squeeze out 15-22 hours since installing Snapdragon Battery Guru. Which has been working great until today.
Here's my situation today:
-100% charge at around 1230am. Light to moderate usage leaves me with
-77% between night before and waking up (only dropped like 2% overnight) at
-830, then i worked from 9 to 1230 so i didnt use my phone too much. But since ive been off work ive been using it more so im not too surprised about my low battery level currently.
But what concerns me is Android OS using half my battery! It says its been active for more than 4 hours and i dont understand where it comes from. Its way more than my screen usage even with a screen time of little over 3 hours.
Anyone know whats up with Android OS? It doesnt tell me what is running when i select it so im lost.
Also ive done many of the suggestions in this thread with positive results. Ive been monitoring my wakelocks and since doing some of the suggestions on here nlpcollector has actually gone down.

Just to benchmark .... I used the phone moderatley ..
I did.. a little over 50 hours of total on time
4.75 hours of on screen time,
2 hours of spotify with bluetooth for the entire time,
2 hours of MapMyRun with GPS running ..
then various text messaging and a couple phone calls
The only modifications i've made to the stop experiance is taking of google's location service for programs, but leaving GPS active .. and changing the screen to auto-brightness, baseline of 50%.
I came from the SGS2 ..... with 1 hour of on screen time and the other spotify and bluetooth .. i'd be around 10-20% after 8-10 hours !!!!!
Mines pretty awesome.

I'm not sure if my battery is defective or not. Right out of the box was around 75% and I drained it until it turned off then charged it to full.
Over the next few days at work it's on wifi and then on 3G/4G before /after work. I pull it from the charger at 7:30am and by 7pm its at 40%. Then on Friday night I unplugged it at 12am with 100% and woke up the next day with 80%. It's dropping like 1% about 10-15minutes. Would a factory reset fix the battery drain? or call for a replacement?
