Awful battery life? - Nokia Lumia 920

Hi all,
Got my 920 a few days ago, and while it's a beautiful phone, I'm finding the battery life to be awful.
I've only installed a few apps on it, otherwise it's vanilla. With WiFi and GPS off and only moderate Internet usage (mostly Facebook and IM+) i get a max of 10 hours out of it.
My Galaxy Note easily does twice that with the same usage.
Is there anything I need to check/look for, are there apps that show what's chewing through my battery so much?
I love the phone but that sort of battery life means it can never replace my Note as my main phone.
Thanks!

I should add, it's running the Portico update. No crashes or random reboots that I've seen.

I have only had mine for a few days, but I have found with all WP8 devices (and I have tried most) a hard reset made a difference to battery life. Annoying, but true it seems, well, true for me. I have no idea if it is a placebo but might be worth trying if you can be bothered.
For your info, I am getting good battery life on my 920.

You need to discharge and recharge the battery a few times before the battery life gets better. In about a week you should find the battery life improves.
It was the same for WP7 too..... The software will calibrate the battery over time.

I actually did a hard reset when I first got the phone home, out of habit really. I don't mind doing it again, but maybe I'll give the battery a few more days and see what happens.

Also check your background apps.

it'll get better
when I first got my lumia 920 the battery life was shorter than my old NL 900.. but after a week or so and after I did a deep cycle now the battery will easily last for 48 hours... in battery settings it usually shows 4-5 days :good:

battery life is hit or miss, some days you'll get wonderful battery life and others its horrible, I know that its hard to measure battery life because you just cant replicate the exact same usage everyday. I find it hard to believe that the galaxy s3 (basically the same hardware) has better battery life, battery is only 100 maH more.
I honestly believe its a operating system/ application issue, I believe that there are some applications that are cycling and wasting precious juice from the battery. better coded apps/ better OS control will really be a big deal in the next os upgrade.

I've found turning off background tasks which are not required makes a big difference on the battery. Each time I install a new app, I look at the background tasks and see that it doesn't get added. Only tasks I have running are weather and a news reader app.
Also, I will not allow location on apps that don't need to. Searching for location when an app opens also drains a battery somewhat.
That being said, with my use, I easily get 2+ days (48+ hrs) of battery life.

May be it have to be synced
In my opinion, one reason why this phone need the run in for the battery life is in the first few days it need to be synced with many clouds, facebook, facebook photo, nokia drive....etc. As this will make poor the battery life in the first run in. But after one week everything done, the battery life becomes better. Just guess.

I've also noticed that with bluetooth turned off I get substantial more life out of the battery(but I tend to forget to turn it on when getting in my car, then I dont get calls on my cars bluetooth). I agree with disabling push and do a manual poll on your email servers, I dont have facebook or any of that stuff on the phone. Im mainly on twitter and on my email.
from time to time I see the Location services running when I unlock the phone, I've disabled the location service on bing search but that still comes up from time to time. Like I mentioned before I think the OS has tons of pros and like any other OS in its "early stages"(I say this because windows mobile has been out for some time pre iOS and Android, but it will get better over time as the company realizes main stream OS are getting replaced as the go to home PC.

My experience with Nokia Phones is they need 1 or 2 weeks to get the full battery life....
The first 4-5 days they really have a horrible battery live.. But as I said it's getting better after 1-2 weeks...
BTW I'm really impressed with the battery life of my HTC 8S, I'm getting 2-3 days out of it with heavy usage...
My Lumia 920 achieves a little bit more than 1 day..

I've had the phone since it was released(when it really bad battery problems), I was going to go with the 8x but I really love the camera on the lumia 920.....

Ok for the past two days I've been using my phone with bluetooth off and i've been getting really good battery life, a friend of mine has a surface rt and he was having an issue with the battery depleting even when he left the device on sleep for hrs, he noticed that after disabling bluetooth the issue with the battery went away, this clearly points out an issue with the os and the handling of Bluetooth.

Surface RT and Lumia 920 have a totally different OS i don't think you can compare them that easy...
And it well known the Bluetooth deceases the battery life of every smartphone... It's the same with NFC (Tap&Send) and super sensitive touch or Wifi...
Just turn off the things you don't need...

My Samsung Note 10.1 tablet has no noticeable difference with Bluetooth on or off (that is, not actually using it, just having it enabled). It's using BT 4.0 which has very good power efficiency.
Any idea what revision of BT our Lumias have?

It also makes a difference if you switch your bluetooth on to be visible or not...
Ii is the same with Wifi you can activate to be notified when open networks are around... If you do so.. your wifi will use more power because it is constantly searching for new hotspots...

Well, it's been a few days & recharges, and it seems the battery is getting better.
Thanks for all the suggestions from everyone. I was severely disappointed with the initial battery life, and while it's getting better, I hope it keeps improving. Switching background data services such as push mail and chat makes sense when it comes to preserving battery of course, but so far from all the smartphones I've owned, this is the worst performing of all in terms of battery. I don't want to have to manually check mail or log in/out of chat, since that defeats the purpose of having a smartphone imho.
It's the only thing I have against the Lumia so far... even though WP8 is not as customisable as my Android phone, I certainly appreciate the design and how it works. I'll just keep crossing fingers for more battery conditioning

I think there is something like a help app from nokia on the phone...
You can disable the live tiles you don't use and the automatic xbox live sync service...
I wouldn't totally disable email sync... I just reduce the syncing interval...
If you have a lot of email accounts (maybe more) it even makes sense forwarding them all to a new email account and syncing all your emails
with this 1 account...
There are a lot of dirty little tricks to improve your battery life... Maybe every
single one don't make much difference... But all of them do...

With a lot of frustration, I have been experiencing high battery drain also, with the phone staying warm even while idle.
Following various comments, fixes, could be' on various forums, I hard reset my new, less than one week old, phone.
I was kind of annoyed, surprised it took a very long time to recover, with a picture of gears churning on the screen.
Finally it booted up with a message, reset or restore. Wasn't expecting the choice. I chose restore to see what's up.
There was an amazing amount of stuff to restore.
After restore completed, my phone was still having battery drain issues. I decided to check out what this back up and restore thing was.
Pardon me I never read the manual. No need to go into discussion of the process.
I then chose to disable back up and restore, soft reset, and boom. Battery usage is now at -2%/hr. instead of -12-20% idle.
Have any of you tried this?

Battery life

ive had my xv6800 for about two weeks now and im still trying to get my power settings tweaked right. granted, i ahve been playing with it alot and probably doing some things that arent conducive to long battery life. One problem is that i dont really know what to expect, so if everyone could please post what they do, any tips/tricks to increase the battery life that get out of it.
also if anyone does think they get good battery life out of theres, what they try to avoid doing on it, that gives you such good life.
thanks

The brightness of the screen is a factor. Try lowering it if possible.
Disable active sync, bluetooth, wifi, and beam when not needed.
Using the GPS drains the battery quick. ( results vary )
Push email also assists with battery drain.
Put your phone on standby when not in use.
Also the extensive use of PIE and Windows Media Player also assists with the drain of battery.
Last if you have poor signal strength this can also be a factor for battery drainage.
There are others out there but these are some that I encountered and learned live with.
There is a battery hack out there that can help you with your battery life. I don't know from the top of my head but search for a registry battery hack.

I think [email protected]$ hit the nail on the head. Everythng stated is a sure fire way to drain your battery quicker. I just got my Mogul and have been playing with it quite a bit even though its pretty much the same thing as my Apache but none the less all those things will drain your battery. I have this thing going on 2 days with very little battery left with minimal use of phone options.
I had previously not had data, so i kept BT always on, never went past 80% with texting and using some programs throughout the day. Now with data, for the last 2 days, wow, down to 20% both days. I turned off BT to see if that can save a little and will turn down the screen a little (was on 100%).

Sprint Hero battery life

I'm fairly disappointed in this battery and will start gathering benchmark metrics,asking others to do the same for more data points and what does and doesnt work to increase.
Currently I have disabled sense ui and reduced widgets down to hardly anything, just a search and taskiller. I seem to get around 10 hours with moderate usage (occasional short call, several texts and quick searches, etc) letting android download background data and check google accounts email, contacts and calendar (this really is the power of the phone, cloud syncing pim). Weather, stocks and other "widgetable" apps are refreshed only on demand.
It's worse than I thought. I went less than 6 hours today with only one quick call (<1 minute) a few youtube clips and 2 texts. I noticed the phone was pretty warm in my pocket compared to my HTC touch (it actually felt cold sometimes if left on the desk) and a few times I noticed that there would be no radio "bars" but most of the time I had 3-4 out of 5 bars (I never have recetpion problems where I am) leading me to believe that something goofy is going on with the radio. I am going to reset since my testing is over today!!

Whit what tool did you test it?
It's still to early to tell but I'm seeing decent battery life. Better than my pre but not great. Certainly acceptable considering I'm playing with it all the time since its new.
i also am seeing bad battery life.. i had court yesterday, and had it OFF most of the day.. and it was dead last night, i turned it on after court.
anyone notice this:
the website has extra batteries
http://nextelonline.nextel.com/NASA...oryID=BSH5110&topPageNumber=0&subPageNumber=0
they say 1340mAh. mine says 1500mAh
do you guys think thats a mistake?

I just looked at battery usage in Spare Parts at various parts of the day and input this manually to minitab. No special app or anything.

I read that the European version has a small battery, but because it is GSM is supposed to have as good or better battery life than the CDMA version.
The GSM Hero has a 1350mAh battery, and battery life is reportedly slightly better than the Sprint Hero even with its more capacious battery. As you correctly surmise, this is due to the Sprint being a CDMA network.
Why Sprint would want to sell a lower capacity battery though, I've no idea!

my battery didn't last a full day either
I am into my 3rd day of usage (on single charge) on my week old hero.
Running on 2G network, turning off all data connectivity, manual reduce screen brightness, minimum vibrate and sound notifications for typing and applications
I have a Sprint Hero and the battery is at half strength not too long after lunch. But since I've only had the phone 3 days, I probably am playing with it more than usual. I'm guessing Seido will come out with an extended life, same size battery. They did with my Touch and it was great! It was very handy having a spare battery when I was out for a long period of time, away from anywhere to charge the phone.
Im also into my 3rd day of usage, and been off the charger all day today... had a couple calls, couple texts, bout 3hrs worth of browsing/facebook/twitter... down to about 60% as we speak so i know its a vast improvement from my tp... hell, 2 hrs of anything on that phone and it would be below 50 percent before the day even really started lol...
There are a number of things you can do to help improve battery life.
1 ) Turn off Wifi autodiscovery. You can always turn it on again if you are at a spot where you know you have a good wifi connection and plan on using it. My Hero was constantly telling me about wifi hotspots that I was driving past. I've found a number of widgets that will turn wifi on with one push.
2 ) Set Twitter, Facebook, and or email to check for updates less often than stock. I don't remember exactly what mine was set to at the beginning, but one of the first things I did was set Twitter to every four hours and Facebook to every two hours.
3 ) GPS is also a battery eater. Turn it off unless you need it.
4 ) Whenever you get a new phone, you ( well, I do, I'm just assuming that you do, too. ) use the heck out of it, playing with settings, seeing what all the programs do, downloading apps and games. Battery life should pick up as the newness wears off.
If you guys want a little more juice, Seidio just came out with a 1750mAh battery that fits in your device's existing battery space and doesn't require a replacement door.

Problem is, whats the point of having a phone designed to have al lthese features if you can't use them as the battery just dies.
My T-Mobile G2 / Hero dies so quick it's annoying.
Yes I've been doing lots of stuff with it this week but to have to turn of 3G to save battery is a laugh. My old Sony phone uses 3G etc and it can last a good two days without charge.
I've kept my 3G on but have kept all the updates to minimum amounts or to be done manually.
Background data also turned off most of the time but again, if it's required, then we shouldn't have to turn off.
It's about time batteries were developed or the companies actually provide longer life ones.
All the testers reviewes keep going on about how great the battery life is doing all these things and stuff, what batteries have they been given to use compared to the rest of us I wonder?

Battery Drain - hardware or software?

First of all, hello to everyone. I have been reading through a lot of threads here in the last few weeks after getting my HD2, especially the ones about battery life.
I have never owned a smartphone, so I have no comparison but I'm barely getting through 1 day of use when fully charged! And I'm not even using it that much yet, Wifi is off, no data transfers, just some texting and calls. I have installed Bandswitch and Battlog, didn't really help though.
Got the phone brand new (T-Mobile US) and haven't done any major tweaking yet, it's still pretty much stock with a few programs that I installed so far.
Do you guys have a similar experience or is it completely different? I love the phone, but if I dont even get through one day of use (and I want to use the phone in the future, not just for surfing but for music streaming or web browsing), I would have to bring it back.
Any help appreciated!
It's just something you have to live with, buy a spare battery, or the extended battery, flash a lighter ROM, adjust screen brightness turn off push e-mails etc etc.
I can get 2 days battery from very light use. i.e. a few texts and calls a day, no Wi-Fi, bluetooth or internet browsing. That's just how smartphones are.
So how do you do it on a daily basis?
My battery is fully charged in the morning and lets assume I'm using the phone for what I bought it for - some music streaming, gps here and there if I need it, some web browsing, calls and texts etc.
I haven't even started using most of the features of the phone and my battery has died twice on my already while I was out at night.
How can that be normal or acceptable? I can't charge my battery every 6h...

Maybe you shouldn't have a smart phone? Battery technology is ****, it's a shame, but it's true. The only thing I can suggest is a spare battery, I carry one everywhere.
I generally watch an hour and a half of video a day on my phone, text, call, use the internet and I can still make a 9 hour day with 40%+ battery left, and just incase I am out and about in the evening before I have a chance to get the phone on charge I have the spare.
But with that said half hours charge from the mains will give you a good 30% topup I very seldom have to swap the batterys and I use a pretty juicy ROM.

or maybe not
Given his kind of use, 2 days should be normal. Right now I'm squeezing 3 days out of this battery, and that's only because I swap it out when it's at 10%, otherwise it could be a little longer... and a few calls here and there is not the only thing I did with it... it's still my work pda after all
Since it's pretty much stock, unless it gets better with time (the first recharging cycles are the worst) and even after a hard reset it won't get better, it probably is something wrong not software related.
Install battclock and check the standby battery drain, shouldn't be much higher than 4mA, up to 7mA could be normal, any higher than that, especially if significant, and you've got something wrong, and found the cause to the short battery life.
First off, buy a couple of cheap oem batteries from here...
Now, these eBay batteries have performed slightly better than the original battery...
Some of us smartphone users are so used to poor battery life we have power charging cradles at home work and car just to keep the charge up... And have spare batteries every in case of emergency...
I take my phone off the charger at 6am to go to work... My avg day is 6-10 calls, 20 reminders, an hour of UNO, an hour as a wifi router and I return home at 5pm with 50-60% battery life...
they are trying to make batteries smaller and thinner so they can make the phones thinner and smaller so battery life is compromised. But you do need to give it some time to settle in.
Back up batteries and cradles to charge them are cheap and an easy solution. So are extra chargers to keep at work, in the car, etc. Most people can charge their phone at least an hour during the day and that should give you all you need.
The only smartphone that I didn't carry an extra battery for was the moto q9c, because it came with an extended life battery. But on these phones, that probably isn't the best option.
So what did you guys do to improve the battery life of your HD2? Are there any specific programs (I heared about G-Profile) you are not supposed to use or did you guys just deinstall all the T-Mobile Apps?
If I can just get 1 day of actual use out of it I am OK with that. I just dont want to have die every second or third day if I use more often than normal...
Any suggestions or may tests I could do? I feel like I could stream music on Slacker for about 90 Minutes and the battery would be dead...
EDIT: Just did Battlog for about 15 Minutes, my phone uses between 15ma and 31ma when in standby. So where do I start, how do I find the culprit?
I love huge screen HTC devices and Im a power user, so my solutions for power issues are:

There is a 15% discount right now, better hurry.
Extra chargers and thats it! Now I browse, calls, emails, music, videos, TV stream (Slingplayer) and maximize all of the other features of my HD2 t9193.
Software and the end-user are the cause behind battery drain. I've got 2.5days out of moderate use so I don't think it's the hardware at all.
Methods for testing battery consumption and proof it is typically software related
Hi,
At the risk of looking like I'm trying to hijack this thread, I started a discussion on this particular subject a while ago as feedback on my finding after reading almost all the threads I could find regarding battery use on the HD2. Lude219 is 100% correct, the issue is always software related (yea, I know there might be exceptions to the rule) and my phone was a prime example of that.
See the thread below that explains how to measure your battery consumption, has logs and screen shots from users you have high consumption and also people who have systems where battery life is more than 48 hours so that you can compare your results.
http://forum.xda-developers.com/showthread.php?t=718173

I'm also sure it's software related. My phone would use app. 2% overnight with all connections closed. This i tested over months. Then suddenly without me changing anything drastic software wise, it pulled 5% per 3-4 hours. So after going thru all the cleaning routines nothing helped exept a good "ram cleaning" . Somehow or other the phone starts processes over time wich consume alot of power. One would have to look into it with a process manager to find out what exactly it is. WinMo seems to be quite sofisticated looking at all the running processes. So my view is , keeping the system tidy might be the only way to save the extra power.This is where the huge diffrence to other platforms seems to be, it can take quite a while until you have configured your phone the way you need it. I am useing the stock rom 1.66 German
thanks you guys for participating and sharing your thoughts.
But now, here is a thinker:
Last night, I let my battery drain all the way to zero and then recharged it at night. The only other thing I did was installing BSBTweaks and Touch X Taskmanager. I also changed my Bandswitch Settings to turn off data when not used and put it at 60 sec (instead of 500 sec before).
And I couldnt believe what I was seeing, I took my phone off the charger this morning around 8.30am and now at 7pm I am still at 84%!!! I did not use the phone heavily but sent and received a few texts, made 1 call and played around with it for a little bit. Similiarly to what I did in the beginning after I got the phone, but then the battery had almost died at 7pm!
I am super happy and hope it stays like that but cannot explain why all the sudden it is that different...
Hi everyone,
This is a very usefull thread, for me it is, thanks to everybody that answered.
regrding the last post, a noobish quesition is
”Bandswitch Settings to turn off data when not used and put it at 60 sec (instead of 500 sec before): how do i do this?”
I remember stumbling upon this setting the day i got the phone and started viciously going through it.
Somehow it didnt store in my memory the path i went that day so i can try doing what the man sugested.
So if anyone can lay a hand, much obliged.
Regards
i lost 12 pct over night in 9 hours with my radio turned off last night and only gmail and texts were open...
with battlog how do i do the test so it stays in standby? it keeps turning the screen on and off when i run benchmark
You may want to flash a new radio. Try a new one each day and measure battery life. I use radio 2.12.50 and have had a good experience.
yeah but with my radio turned off the radio shouldnt affect it shoudl it?
i use blackberry to stream pandora radio thru aux for about 8 hours a day and it still has 2 bars left after that.
HD2 just sits there and kills the battery lol
what kind of phone is that when you have to disable all its functions every time you dont use it?
seriously this is called unfinished product or poor design, that is beeing sold to customers as a next best thing.
you guys can argue with me all you want. i heard many excuses from users advocating the companies. such as. if you dont like this than pay more for a better product. well HD2 is a better product, its a 500 dollar phone damn it.
but you dont realize that even the "better" products suffer from same underdevelopment syndrome.
companies spend millions on consumer research and consumers spend millions on **** they dont need every year. cows eat grass, consumers eat garbage made by big companies.
where are the better products? they dont exist because it became "normal" to have a faulty OS or for your phone buttons to fall off, or battery to explode.
companies worked long and hard to make consumers get used to the idea that garbage is just a part of life, and worked long and hard to minimize costs of production, and cut corners.
which corners?
the final QA testing that is not beeing done by a company, so they can release the phone 3 months earlier, the consumers pay for the phone and test it.
we work for the company and we pay for it instead of getting paid.
the phone breaks oh how sad ,
company takes note(dont use this cheap glue or the buttons fall off, get a lil more expensive glue next year)
so they use better glue and cut another corner and we buy another "new and improved phone" and this time screen goes dim oh dang not again...and it continues.
do you disconnect your car battery every night so it doesnt die? or when you buy a lexus do you drive with your AC off because it cant pull the car around when ac is on same time as the stereo?

Finally did the OTA update... crazy good battery?

Hey guys... I finally updated my E3D with that update. My sister and dad both updated theirs when they first got it.
I'm getting really good battery life. Minimal usage yesterday, but after 16+ hours I still had more than 60%... I even played a little N64oid.
However, my sister and my dad both get pretty bad - decent battery life. My dad doesn't use the phone nearly as much as me.
I wish I knew what settings are doing it. We all have the same settings but my idle time loses me like 2-3%/hr but for them it can be up to 7-10%/hr.
Anyone in a household with more than a couple E3D's getting this varied battery life?
Settings are virtually the same, and location isn't a big factor either.
A lot of things impact battery. If the settings are the same across all phones perhaps the drain is app related. If you really want to test you should factory reset all phones and then check. This way all truly have same settings and apps. I would bet at that point they all drain the same.
I did the OTA and my battery life shot up instantly.
Before the OTA I would have around 15 hours of light to moderate use of text, calls, and browsing before it hit 50 percent. Now, I would basically do the same things but I can go a full day before it hits 70 percent.
I bet you they use the phone more...calls..facebook....etc..friend of mine gets couple hours...and he plays games non stop.

Bigger battery capacity

Hi all,
I love the Sony Tablet except its battery life. for something that is so huge compared to the others similar products out there, I am sure that they could have squeezed a bigger battery into the unit.
The power capacity is pretty weak. Let's hope that Sony offers a higher capacity battery size. I would gladly pay to upgrade it.
That's weird, my battery life is fantastic. If I play games on it all day it'll last 8-12 hours, but if I just use it intermittently and moderately it'll easily last me a couple of days. On standby it only uses a couple percent a day if that!
I'm the same as unclespoon. Even during heavy use, I get about 9 hours, which is way better than my old Galaxy Tab could ever muster. Standby usage is crazy low, its fantastic!
Not sure what you mean either about being larger than most other devices. The Tablet's 9.4" screen is smaller than almost any other full-size Tab out there (including the iPad) and since the back curves, theres not actually a lot of usable rear space (look at how thin its getting at the thin end, now imagine trying to fit a battery in there!)
I'm not sure you'll find a Tab out there currently with a better combo of size/battery life. The chunkier Toshiba Thrive will last longer, the thinner Galaxy Tab's will last even less, and my Tablet S always outlasts my iPad, so it might just be your device. Try checking Settings -> About -> Battery Use
I'm of the same opinion as the op. My tablet s has dreadful battery life and especially when it isn't doing anything. (50% usage is system standby) my old galaxy 7 was far far better (charged about once a week)
I believe this may just be because it is new (only have 1 full charge) as my galaxy s2 was initially unimpressive and then lasted 3 days of moderate use without charge. Hoping the same will happen to my s1.
Time will tell
My only guess was that you did a shoddy job of conditioning the battery. My old Galaxy Tab (the first 7" one) was hopeless, but when I replaced it, I conditioned the battery better and it was a bit better.
My Tablet S lasts for days and days and the standby usage is tiny. Check whats using your battery in the Battery Use screen and get back to us, we might be able to help..
I noticed advanced wifi lock was causing massive amounts of wakelocks (8 hours out of 10 according to the stats in settings/about).
betterbatterystats is not available via market but I am trying out the XDA APK now

I noticed that as well. If you have Advanced WiFi lock activated the tablet won't go into deep sleep mode, there of massive battery usage. I still have Advanced WiFi lock on my tablet, but only activate it when I need to download/update something that takes time. Otherwise I turn it off. It's not worth the battry drain.
Wow. Your battery life are fantastic. 9 hours? That's huge. I have not used my Sony Tablet till flat but given the rate of battery loss think maybe the most is about 5 hours which is similar to what many reviewers are saying.
Just can't imagine that those reviewers are so far out of the ball park compared to you guys. I am using juice defender Beta. Not to sure if its helping or not. But at least if I not using WiFi it shuts it off automatically.
My battery used to drain badly during standby. I found that the Friend Stream service was preventing the tab from sleeping. Killed the service a while ago and battery has been fantastic since. Pushed it to 3 days with light use. About 3 hrs of browsing and facebook. My battery level is at 68%, been off power for 20h40 mins, and used for about 4hrs today - facebooking, Internet browsing. Note that no specific conditioning was performed.
What are the settings that you have on your Tablet? Auto brightness, background sync turned off ?
how did you stop friendstream, and what the heck is it, did you just kill the process and it stayed dead? (sometimes as u know u kill process but it will come back).
Good question. What is the Android software revision now. My is Android 3.2.1 (revision 2)
I acutally just uninstalled the crap-app. nothing I use anyway. It is an app for facebook, twitter and other social networks. So just get rid of it. Uninstall and be happy
my bad. I confused the HTC name and Sony name.
Social Feed Reader was misbehaving. Once started it kept running... rather than dropping off to sleep (and into Cached Apps).
Something wasn't right so I force stopped it and it stayed dead.
An additional note - the Setup, Applications, Running Applications feature isn't 100%. Some background apps aren't displaying as running or Cached. Go figure.
So any special method to stop the social feed reader?
I'm getting those kinds of numbers on mostly auto brightness (and sometimes lower, at night), with background sync turned on, WiFi sleep policy set to default, and no battery monitoring or saving apps running. The only thing I did was single initial conditioning cycle and since then its been great.
Also note that software-decoded video files will take a lot more of your battery than the equivalent properly encoded file. I havent had any trouble with Social Feed Reader, but I never even set it up and judging by the many stories around here, I would uninstall it if you're worried about battery..

Hi, that's good to know. Thanks for sharing. Unfortunately think I screwed up the initial conditioning. so I guess I will have to live with the 5 hour battery of my Tablet.
Btw how do you do battery conditioning?

In Setup, Applications, Running Services have a look at the awake time (listed on the right side) of the running processes. You'll note that system processes (the ones with the Android icon) have been awake since last boot.... but you might finds others that are as well. I noted Social Feed Reader showing high awake time and decided to nuke it. Simply click the offending app. You'll be given the option to stop the app... which is what I did. It's an app so doesn't restart once killed. Hope that helps...
Final thought: at the top right of the screen there's a 'Show cached processes' option.
The could be an offending app in there. Kill any installed app you suspect might be a problem and see if that helps.
my battery life is excellent.
