ICS Battery Life .. wow

I built ICS AOSP and slapped it on my wifi xoom - wingray WOW the battery life is amazing .. Granted, this it with VERY minimal use (checked my email a couple times during the day and that was it, screen off,) but I've never seen anything like this ..
I almost wonder if this is a mistake and the OS battery stats are bunk lol:

Pretty slick. I can't wait to get it on my Xoom.

I'm going on hour 48 and still have 79% battery .. only using it for brief email as I've been sitting at my desktop for the last 2 days pretty solid though ..

battery problem
Hey guys, i've upgraded my Wifi Xoom to ICS EOS Team nightly 55 and since then my battery drains like crazy while wifi is ON.
Also i think my wifi wont turn off when i lock my xoom.. i can see in battery managment that wifi bar is always blue even if screen is not.
Should i try another nightly?

i'm on cm9 and the battery life is fine .. i haven't tried eos yet so i won't be much help .. does cpu spy(market) show your proc as sleeping?

Cpu seems to be in deep sleep while xoon is locked..

I've always had a great battery life with my xoom except when I used Netflix on HC, either stock rom or tiamat. If I was able to get 5h00 of netflix out of a fully charged battery I was happy. Now with the ICS EOS rom I get at least 7h00 + some browsing time. It made a huge difference.

from the very first day i bought my xoom whenever i select the sleep when screen turn off option from the WiFi it changes back to never and now m using ICS still have the same issue still can get 2 to 2 and a half day with the issue

Battery life seems about the same of Honeycomb to me. But I have the Xoom since Christmas and I switched to EOS nightlies very soon.
With heavy use I always have about 8 hours of screen on.
Now I have 27% after 2d 19h 26m with light use: mails, some internet navigation, some pdf, wi-fi always on during the day

THis is my battery usage.. afte one day the battery is at 6% with only 2-3 hours playing some games (without wifi or cpu High usage).
Look what happens when wifi and screen is on!

I'm on EOS nightly 59. In 1 day 18 hours mine has 9hrs of usage in Android OS. But I've really only used my Xoom for aboutn1 hour and 20 mins. Strange.

got 23 days of standby almost 0 use on stock honeycomb
running the same usage test on stock ICS
14 days and Im at 58% which would mean a rather sizable improvement if it holds true on a full discharge.

Nexus 7 Battery Life

Hi! I recently got a Nexus 7 and I am somewhat disappointed in the battery life. I am only getting around 3 hrs of battery life and is draining quickly while idle. The battery is also draining while being used while connected to my pc. I am using Jellybro rom along with Trinity Alpha 64. Can anyone recommend the best Rom/Kernel combination for battery life ? I read that Trinity is great for battery life so I'm doubting the Rom (however it works great on my Galaxy Nexus). As I dont always use the same things on my tablet I cant really test the different roms myself.
Thanks

I'm getting great battery life on my stock N7 :|
I tried it the other day, used it all day and it died after around 8-9hrs. Was tethering via bluetooth, brightness set to auto, and either played games, used FB messenger, or read Wall St Journal frequently throughout the day.
Sync and location enabled.
Oh and the N7 will probably discharge faster than your PC can charge it. Typical USB ports on a PC only output .5A of power. Chargers meant for tablets usually provide about 2A of power. So thats another issue.
Might I suggest running the N7 till it shuts itself off due to no battery, then letting it sit and charge overnight till its 100%?

Thanks for the reply Can you please tell me the Screen on time ? Since then I switched to Paranoid Android so I'll how it goes but maybe the stock rom has a better battery life ?

Last night I got 19.5 hours on battery with 7.5 hours screen time on paranoid android. I'd say its safe to say that...

I'll unplug my tablet for today though and by tonight maybe I'll have some interesting results for ya.

If its enough to make you mad then its prolly not right.
To say your doing in wrong would be a far shot but your tablet is definitely doing it wrong..lol. I was just saying the other night to my girl that I was super happy with the battery because it lasts all day for me. From 7am in the morning till 12 at night. Of course im not using it every waking moment but I do check it/use it as much as I would have normally used my phone. During work I am on wifi till about 430 and then from 430-8/9 while im in class im tethering using it almost the whole time, then when im home for the rest of the night I will be on wifi. The things I do vary from webbrowsing (reddit, xda, etc) emailing attachments, listening to google music and GPS/texting. (yes I use tablet talk which is why I rarely use my phone anymore except to setup tethering)
If you are having any issues with your battery I recommend to get a battery app to reset the stats and try again. If not return to stock then try that method again.. then if NOT return.

Just turn off your google account auto-sync and your battery life should increase dramatically. I use the power widget to toggle sync.

Okay here are some screenshots of my battery life... Not sure if its uploading properly though since im doing this through the app.....
EDIT: Looks like it didnt work... But basically I had about 20.5hrs of total battery time. Screen on for a total of 5.5hrs. Bluetooth on the entire time, WiFi on for about 6 hours.

My N7 discharges faster than the google provided AC mains charger can recharge it. That seems pretty pathetic to me. How is it for others?

Post your battery life results!!!

I've made a thread like this in the Sensation forums and it was quite popular so I thought I'd make one here as well, as I'm really curious how far can the Xoom really go in terms of battery life !
So the general format of how the posts should look like should be this:
Running (stock/stock+rooted/custom(name) rom) on my (model).
Here is a picture (insert battery life screen shot).
I'm (undervolting or no undervolting)
PS: Make sure you don't charge your xoom as it makes the results invalid and useless!
OK! My turn:
I'm running Stable EOS 3 custom rom on my MZ604 WiFi only Xoom.
Here is a picture of my battery results:
online photo sharing
And this one:
image
No undervolting was done.
The only question left is, can you beat me?!

I usually don't take pictures of stuff like this, so next time when I get over a week of usage on my XOOM I will post it here. I should note I put it in airplane mode and have the WiFi and bluetooth on all the time, though I believe the WiFi does turn off after the device goes into sleep. It's a MZ601, uses Team EOS nightly builds always on the latest. Stock speeds and yeah.

A whole week? Isn't that a bit exaggerated? Mind you, I just got the xoom so I can't talk, but a week? That's a nice result.

Pretty much, I don't use it much, maybe one or two hours most each day.

Mine is a bit bias as I'm forever flashing and trying to edit/theme and therefore loads of time is spent in recovery/rebooting/'android upgrading'
but anyway, here it is:
CM10 Nightlies

Sure mate, just under 3 hours, 2hr 55mins to be precise.
I generally think I get pretty decent battery life out of my xoom

The only part really worth posting is the screen on time.
This damn thing can literally go weeks technically "on" because there is practically no battery drain when its "asleep."

In some ways that is true. However, what if somebody just charged it to 100% and played with it non-stop, so that the screen on time went to 12 hours. You say,"That's amazing". But some people don't have the time to play with them for 12 hours straight So the overall time adds towards the actual battery life, since it still loses some battery life during the sleep or the night. Take me for example, I play with it 3 hours a day and can go for as long as 2 days before charging it again.
I've said this before, but I'll say it again. This tablet is amazing !

Here are some pictures:
As I stated before I don't use my XOOM much, but I did use it a lot for music streaming to my bluetooth headphones and also watched a movie on it. Lol
And oh I had about ~35% left

EOS 3 Stable. No performance mods. Usually see a week at least between charges.

Help with Battery Life/Power Issues

Hey all
I've been having massive issues with my battery life recently, it's never been great however it's actually gotten a lot worse post Kit Kat. I've taken a few screenshots on a few different apps like GSam Monitor, Wakelock detector and Battery Widget, I was wondering if somebody could help me diagnose the issue. Or at least just give me general insights into the numbers that I'm getting in terms of battery life.
EDIT: Just noticed a new issue where a couple of times my battery was somewhere in the 40's and then the phone crashes and when I start it back again it just has about 2 % battery left. Weirdly enough, after charging it for a couple of minutes, that battery now goes up to 30%. Would love to know if somebody has had a similar issue and what might be a way to go about trying to find some sort of solution.

Hmm.. That's weird listen--- >
1. If the screen is jittering and phone crashes... Battery is bad..
2. Try flashing stock firmware... Might be a software issue
Sent from my Nexus 4 using XDA Free mobile app

same battery issue here. Its not because software. i tryed CM11m11, Ubuntu Touch, stock.. same problem. Im waitting new battery, because i was not that gentle with batteru when i was repalcing camera 15 days ago.
Usualy moment before phone restart, lose sim signal, then freeze and restart

If flashing stock doesn't resolve it, I'd say the battery is dying. I went from 2 hours between charges to 12-14 with a new battery.

I installed stock rom by tutorial what i found here, but problem stay same. Waiting for new battery

My battery is also dying (switched to new phone now). It averages about 1 hour of SOT over several days and it's only wifi only. I guess I could swap out a fresh one but it goes to show that we need easily removable batteries but they just don't last that long.

Experienced the same issues like you did. A friend of mine who is used to fix iPhones did it for me. I just bought the new battery and paid him a beer

Did your battery life return to "normal"? Not that the Nexus 4 ever had great usage time. I might attempt it myself as a challenge.

It did. I've connected my LG G Watch to my N4 so Bluetooth, GPS and mobile data are always on.
But Facebook is a Batterykiller I'm working from 07:45am till 4pm and when I come home I've around 40%-50% battery left.

Intriguing, but what is your SoT?

Around 3-4 hours when my Bluetooth, mobile data(3G) and gps is on. But I can't tell it exactly cause I'm not using it that much anymore cause my primary phone is the N5.

I replace battery, now everithing works perfect. It was battery problem, not software.

I've been waiting for my battery to die. This is my normal use. I just do what I normally do.
Streamed music to my car while driving for a while
browsed reddit/xda and other forums a lot... mainly on WiFi.
Had data/wifi disabled when I didn't need it on... really no point. Takes 3 second to enable it again
~50 texts with a few MMS sent. I'm not a popular person
checked voice mail once.
2-3 bars where I live.

Nope. Didn't configure it yet. I wanted to test out everything to see IF i needed to use greenify.

This things a beast no doubt!
This is normal mode with nothing special running to save battery btw

Max I get is 17 hours with 6 in a half to 7 hours battery life.

Nice! Yeah, this thing just goes and goes...took it off charger yesterday and it's still nice and full! :victory:

You've charged the phone to like 80% somewhere in between the discharging, if you look at your graph...

LOL Oh. Yeah your right. Didn't realize that. I have wireless chargers everywhere "even made one that was non-slip for my truck" must have put it on one sometime and forgot. Sorry bout that guys. Didn't mean to post a false reading LOL But still I've seen pretty close to those numbers several times without charging.. Depends on what I've been doing of course.
Btw That was an old screenshot I just had in my gallery from not long after I got the phone.

Ive gotten 34 hours out of it so far im really impressed

I have the moto Maxx, Mexican firmware. I´m from Argentina.
Could you tell me guys the version and the baseband of yours?
Because it seems that the latin america version the battery is barely poor.
Thanks!

Damn... Going beast mode with this battery. Would've gone longer, but gotta use it more tomorrow when I'm out. Ya, I know I only have 4hrs of SOT. Haven't been using much

I assume anyone getting more than 48 hours of battery life is turning off data, or at least disabling updates/background data. Just out of curiosity, do you always keep that turned off, or do you just do that when you're seeing how much you can squeeze out of the battery? In my mind, the big reason to get a device with a big battery is so you don't have to baby the battery like that.

I disable data and auto sync. I've done this for every phone I've ever owned. Not to preserve battery life, but I have no need to have it on 24/7. I turn it on when I need it.
