Battery usage after 3.2

So I finally gave up waiting on Motorola and switched my UK Wifi to the US rom. I unlocked, flashed the relevant images and did not relock; then got the OTAs for 3.1 and 3.2. Everything seemed fine but now I've noticed the battery is dropping significantly quicker now with the same usage. I've also checked the battery usage and noticed that there is no "Tablet Idle" entry, so does that mean its constantly staying awake? And does anyone know how to fix it?

my battery life improved with 3.2

I did exactly the same, install the stock US rom on my non-US xoom and update to 3.1 then 3.2, and I noticed the same battery life drop.

I noticed that my Xoom was staying awake pretty much the whole time the screen was off so tried uninstalling a few apps and sure enough that solved it. If you have the CNN app then try removing that for starters

Cell Standby drains battery

Hey guys,
Had my phone fully charged last night, went to bed, and 7 hours later the battery was at 19%. Quick check on what's using the battery revealed Cell Standby was the major power factor, using 60-some% of the battery.
Any one else experiencing this issue? The X10 is rooted, Android 2.3.3 installed.

Too much updating/synching going on maybe
Try increasing the time between sync on you running apps( weather,facebook,email,etc)

How is your phone reception/signal?
Cell standby usage is high for me as well, but that is due to the poor signal at my house.
The poor signal will drain your battery

Signal is good.
The syncing hasn't changed. mostly battery lasts for quite a while. I think it may be caused by the Facebook app.

Battery Drains QUICKLY!

I got school at around 6 am. By the time I eat lunch it's already at 57%. By the time I get home around 5 and it's already at 17%.
All I do is listen to music (doubletwist/playerpro) and play Cut the Rope, WTF!?
Cell standy by is 46% in batter usage followed by wifi with 11%
any help guys?

What I tend to do is have brightness down to about half. Have you also tried fully charging the phone, taking the battery out and charging back to full? I sometimes find it drops down but regenerates itself.

Brightness is below half,I never go over. WiFi is on but not all the time.
Stock rom 2.3.4 rooted

Do you have data off?

How's your phone signal most of the time? It has been proven that low/bad signal drains battery quicker than good signal.
Sometimes certain buildings/rooms have pretty bad reception making it a huge drain for your phone.

This is a useful piece of information, however is not really practical. Ideally we don't want to be turning off our phones on every charge :/
I myself own 3 batteries, and alternate them (I have a wall charger for the batteries)

what ver are you using if 2.3.4 the battery issue is fix.

I get 3 /4 bars, at school right new and yea some times I get nothing, especial ly during the subway ruse which is an hour
Sent from my R800i using XDA App

Once I updated my phone to 2.3.3 I noticed that the battery life was sub-par, only lasting 3/5s of the day on a full charge.
I proceeded to root my phone (as I don't have the money to unlock my Big Red Bootloader); after installing SetCPU I took down the clocking meter 1 notch (768MHz) and the phone is stable with not difference in performance (so far). Doing this and removing some unneeded bloatware has increased my battery life 2.5x and I can go almost 3 days on a single charge.

xiEvo is correct and I've read a lot of good stuff regarding battery life with 2.3.4. I can only begin to imagine what kind of battery life I'll have once I get that update.

I'm 2.3.4.
Honestly I had the best battery life with 2.3.2, IDK why.

Someone help me! (BatLife woes)

Alright I wasn't going to make a thread on this because this topic is already discussed elsewhere naturally but I feel my situation is different. All over the place I see people reporting great battery life with ICS.. well mine is HORRIBLE. I just flashed the latest nightly for Pete's bugless. I didn't change the kernel. Everything is stock. Only a few apps installed. Noop for scheduler and ondemand for governer.
The phones been off the charger for 55 minutes and I'm sitting at 76%. Idk what's going on. I've tried so many rom/kernel combos and I seem to get the same exact battery life no matter what. Around 6-9 hours with less than 1 hour of screen on time.
Things I've tried to combat this:
Undervolting
Freezing apps
Restricting background data
Underclocking
Brightness set to auto
And I'm sure a few other things I'm forgetting about. I've done all this and still get ****ty battery life. I've flashed the new radio hoping that it would solve my issues but no dice. My signal strength reports at -67 dbm yet the bars never go over 2. 3g or 4g. Even after updating plr.
On gingerbread cm7 I ran brightness at 70%, ocd to 1.4ghz and always got 15+ hours.
For the love of god someone help me. Cuz I think my phone hates the cream sammiches.

try this kernel, trinity teuv underclocked/undervolted kernel, oc'd gpu http://goo.gl/rY6ga
and do not set brightness to auto, its a battery killer. i keep my brightness at about 20-25%.
also, be sure to fully discharge your battery then charge it completely, after 2 or 3 cycles you should be good.

I do this every day lol I let the battery drain to around 15-30% before I plug it back in.
Screenie: 1 hour later and I lost another 25% this can't be rom or kernel related. As I have tried trinity already and the same thing happens

Ugh. Another 20% gone. Its only been a half hour from the above screenie. You guys see my dilemma? Lol **** me.

i was having horrible battery drain after flashing a new rom & kernel - i finally figured it out that my APN settings were messed up and I re-entered them according to the correct carrier settings.
i don't know if that will apply to you since it looks like your 4G data is working properly, but since I was on wifi 99% of the time, as soon as I went off, my data didn't work. but it's something to look at.

4 hours later I'm down to 4% from a full charge.

Could you try better battery stats to see if something is holding a wakelock?

Turn Data usage off :/ i think Fb or some app is using your 4g

I would be interested to see what your battle life diff is without 4g switched on. Also in that 4 hrs what was ur screen on time?
Have you thought of trying a new batt? Just got an OEM Samsung for 5 bucks on eBay. Worth a shot.
Oh remove fb app it blows...install friend caster way better less batt make sure you change the sync interval.
You could also try green power from the market to manage your data use while screen is off.

Ok here's how my battery performs back in cm7 nightly 174 gingerbread. Almost 4 hours and only 25% chipped away. If you look above you'll notice I lost more than 40% in the same time with ics. And I'm doing nothing different. I'm even overclocked to 1.3ghz ondemand with noop for a scheduler.
I think I'm sticking to gbread until official source is out. Maybe then ill get the same battery life.
Sent from my Nexus S 4G using xda premium

That is really weird, if you have time try Milestone 3 and SG's latest kernel and just leave the settings stock . I get wonderful battery life with it hopefully you do to
Oh and are there any apps you are using on ICS that you aren't on CM7?
Sent from my Nexus S 4G using XDA App

Nope. Lately its only been a handful. I actually have more apps installed on gbread to achieve some of the features that are baked into ics. I just don't get it. Ics hates my phone. I even used the GPS today. So weird.

This. If you are installing the same ol battery-draining POS app then you are not going to fix it with any rom or kernel.

So you guys think my batter watcher widget is preventing my phone from sleeping properly? Ok.. I'm on cm7 right now. Battery is def back to normal. And this is with bacround data on. Ill delete bw and get better battery stats.

Better battery stats is not the same thing as other (mostly useless) monitoring apps.

Look. 16 hours on gb. If none of my apps are killing the battery then what could it be?

Regarding battery life

Hello
Long time Hero user who switched to blackberry and now back to android. I've had note 2 for 3 months now and I'm actually disappointed from its battery level. Not that its not enough. .it just didnt live up to its expectations
Through constant whatsapp messaging only (today) 40% drained in 7-8 hours. . I know its a long time but shouldn't it last longer or is 3g that much of a battery usage?
Also does charging with a 2a non official charger might affect my battery? And with the time frames I have available for charging I can never get a full charge. .does that matter?
And is pile stocking on applications and games affecting my battery? Even if they are not open? (Currently using go power master for that)

Show some screen shots of the battery graph. I was just wondering what was your screen time to get a better idea.

You can click on that little chart to see a more detailed view of your battery consumption. Your battery life is a bit on the short side (compared to mine at least), Im guessing the screen is the culprit. Do you have brightness all the way down? How much screen time does the phone get?

@Shei77
For me is battery consumption pretty fine. It depends of course what I am doing with the phone through the day. For example yesterday after whole day "playing" with phone from time to time I had around 70%. I am chargin it when I go to sleep because still if I have in the morning 30-50% it wont make it through day when I dont have option to charge it. Just to add, I have Wifi and GPS always on.

If constant messaging for 7-8 hours means the screen being on for 7ish hours, you have ridiculously good battery life at 40 percent..

I'd say your battery life is fine, im guessing maybe even better than mine. Im doing 6h 37m right now with 69% left, H+/3G always on, with moderate screen time and a bit of gaming.

Huh..what about charging?
Also any tips for extending? Ram keeps filling up after some time..is it cause I have a lot of applications?

As shown from your screenshot your phone signals are really bad. That might be contributing to the drain of the battery.

I think your battery life is fine :good: Usually with my note 2 i can do 4 display hours and 1 day or more of battery life. 3g/h+ always on, lumi 50% all sync on, calls, gaming and web.

This is the current on screen which is a few hours after the first screenshots
What can I do about signals? And if I have a lot of apps do they consume battery through background?
Sent from my GT-N7100 using xda premium

Really, your battery life isn't that bad. The 7 or so screen time hours you'll get if that continues, is pretty good!
And to your other questions, charger type doesn't affect battery performance. Charging time should take around 2,5 hours from 0 to 100, if you're far away from that, the charger might be at fault.

Charging usually takes 3 hours for a full charge and according to my charging current its using 1698mah

I updated it just a couple of days ago I need an expert opinion on how good my battery's time is.

^No offence, but without screen on time a battery stats is just meaningless!
So kindly post your 'Screen on' time.
@shei77: You're on H+ and you're having almost three hours screen on time, with 60 odd percent left. That is very good battery life.
'Swyped' from my GT-N7100

Maybe a bit OT, but what I have noticed is that when the phone reports fully charged, Elixir widget still displays 1600mA being charged into the device? Also, when the battery is full at 100%, the phone is still pretty warm! I don;t remember my HTC did that? It was warm, but when it reached 100% it cooled down and was not hot anymore... I tend to keep phone in charger in the evening because I use wifi hotspot....

My battery life is awesome I'm on cm 10.1 rom with uneak kernel, cm 10.1 is smooth and great performance and great on battery life,
I have attached a screen shot of battery stats...
