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?
I now have this phone for a week and I'm globally satisfied, it's reactive, good navigation, htc quality... but it seems that the autonomy is very bad. For instance, I fully charged it and unplugged it at midday, I sent 5 or 6 SMS, 15min of navigation, no Wifi or bluetooth activated and I already have to charge it. Hardly 7-8h of autonomy for a high-end phone, it a shame..
I hope it comes from a poor optimization of Windows Phone 7 and we will have better results soon...
Do you experience the same issue?
No major GPS usage?
GPS & WiFi are the main battery drainers. Intensive use of 3G / apps also contribute. Reviewers are still holding with full day statements without much GPS or WiFi usage.
No I almost never use GPS on my phone. Today I've disabled 3G to see if it's better (it should be). Nevertheless I've read a few reviews telling that the processor could be responsible for this as it's an old generation one and not really power efficient.
From a few texts and 15 minutes of navigation, I find it hard to believe the device drained primarily in standby before 7 hours.
I know some people who said that it seems the life got better after a few charges, but you say you've used it for a week.
That's weird, I get almost no batt drain unless I use the net/apps or make phone calls. It's midnight right now, and after a few sms today my batt is still at about 90%.
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?

what are others thoughts on some of the pros and cons of this update? i'm thinking it will actually save battery to have wifi 'always on' in standby mode rather than repeatedly switching between a on/off state which uses more energy.
It will definitely eat more battery if it's always on under the lockscreen...
Also there is an option to deactivate notifications when new wifi hotspots are around.. if you are about battery life you should deactivate this..

I keep my Wifi always on because it consumes the least battery (vs 3G, LTE, etc).
If I don't play games on my Lumia 920 the battery can last 3 days.
This update is freezing my phone Dunno why but I have tested it. I occasionally get a freeze now and then, but when the keep wifi is on, it is like every couple of hrs... Will test it more though.

Wrong unless your phone is using 5-year old wifi chip.
Correct me if I am wrong, but is the wifi on this phone an on demand type system? From what I see on mine, the wifi unless being used for an actual update or downloading other content goes to sleep when the lock screen is on. It then wakes up if there is an update pushed to it or if something else needs it or of course if you unlock the phone. At least that is the way it appears that mine works.
Also your radio service are going to use much more power than the wifi will as they are higher power transmitters and receivers. There is a reason wifi only works within a few hundred feet and radio works for several miles that is due to the power difference. Of course with more power you get more battery consumption.
In the case of conserving the battery you are better off to use wifi when possible, leave it on and let the phone control it.
In my experience keeping Wifi on permanently lead to a remarkable decrease in battery life. That will depend on where you are though. If I have it sitting at home where it has Wifi connectivity it's likely that I would see better battery life because all actual transfers will happen via Wifi. At work though it can't connect to the Wifi network (private phone, work network) and so I have 3G running anyway while the phone keeps looking for Wifi networks to connect to.
The problem boils down to the fact that while you can switch off Wifi completely because everything can still work using 3G you can't switch off the phone part completely because only data is done over Wifi but you still need the mobile connection to receive calls/SMS.
I would suggest to anyone to simply try out what works better for them. For me it worked best to let Wifi deactivate automatically as it had been the default in WP since WP7 came out.

Maybe Wifi is using less power when you are downloading something and need a lot of data... But when your phone is idle... Constant on Wifi is using far more battery power than 3G that checks for email or weather every 1-2 hours...
Simple enough...if you are consistently in an area with a WiFi signal, leave WiFi "always on"...it will consume less battery. If you're in an area without WiFi signal then turn it off, as searching for a signal will help run your battery down.

Again, simply not true unless you are using a 5-year old phone. Even if you are in an area that has no wifi connection, the extra drain caused by searching for Wi-Fi networks is minimum in a modern OS and modern chipset. I have left all my android phones (the ones that offer Wi-Fi always on feature for a few years now) wifi on all the time. Never have felt much difference vs if I turn wifi off. It annoys me that WP didn't offer this capability for so long.

I tested a lot of phones Android and WP, my experience is that wifi always on is a battery killer... And I'm talking about state of the art hardware... It's just my 2 cent's but i keep it off...
When I don't charge overnight and wifi is always on my battery drops about 40%
with only 3G on about 8-10%
Foxbat: you can leave it any way you want to do it. I'm not saying Microsoft should remove the feature. But in my experience keeping Wifi on kills the battery faster. I tested it for my use case with always on and with Auto and in the end: Auto it was for me.
The best advice you can give to people is: try it out yourself and you will see what works best for you.
A picture or two says it all. See the attached files for my two testing: one with wifi always on for 24-hour and one with Wi-Fi in auto mode for 24-hour:
The right picture shows 0.0%/hour under current discharge rate... pretty impressive

The keyword is 'Current' -- means at that moment. You can derive the same thing from the left in various sections. The key here is that I don't see any discernible difference. Certainly not a battery killer in any sense as you claimed.
If you look at the first 12-hour period of both chart (when the phone is mostly sleep and not used), the result is almost identical. FYI, there are three push emails connected all the time: Hotmail, GMail and Corporate Exchange Email.
Yes the keyword 'Current' -- means at that moment... so your phone is not discharging although your screen is on... Very accurate app...

So, what you saying is that if you have the screen on, you will see your battery percentage drop immediately? You should return your phone if that is the case.
Battery app get its information from the phone OS reporting. If the OS reported the same battery percentage over a short period of time, the discharge rate won't be anything other than zero. That's limitation of the platform, not app.
Instead of criticize the app which is not the point of the post, why don't you post your findings where leave Wi-Fi always on kills your battery?
it' % per hour... and your phone is using currently using 0,0% per hour so if you leave it like that it will run for ever... so where is the mistake?

% per hour is a unit of measurement. It doesn't mean you have to take one hour to measure it in order to claim its rate. That will be average rate on that hour, not current rate which is meant to see what your current usage pattern is. It can't be used to predict your battery life. If you notice that when you take your phone off the charger, it will stay on 100% for quite some time before it starts to drop. Does that mean your phone battery can last forever? Think about it before post these ridiculous statements.
Foxbat - you are trying to tell us how our devices should behave while we are telling you how they actually behave in the real world out there. You can repeat your 5 years story as often as you want to but it clearly doesn't live up to the factual reality we experience every day and I guess after trying it out with different ROMs on the 920 and leaving all other settings the same I know the effect it had pretty well.
Nice to know though that you are having a different experience with different devices.
No idea if this is the right place to post a feature request -- I've done a lot of searching and this seems closest.
I've been doing some testing here in an area with little-to-know cellular coverage. A substantial part of the world is in this situation. What I've found -- and this can be no surprise -- is that battery charge life is abysmal as the device seeks in vain for a good signal. What did surprise me is that this search and the resultant battery drain continues even when the device has a strong connection to a WiFi network. By going into airplane mode with WiFi enabled in an area of little cellular signal, I've found an enormous saving in battery life, with no loss of functionality -- still have WiFi calling and everything else.
With WiFi and cellular turned on, I'm burning 4 to 5 percent of the battery per hour (Pixel 6a, current GrapheneOS, normal use). With airplane/WiFi only, no searching for a cell signal, same device and same amount of use, I'm using well under 1 percent per hour. Battery life that was measured in hours is now measured in days.
What's necessary is for me to turn on airplane mode with WiFi enabled when I'm on WiFi, and turn airplane mode off when I leave WiFi. Of course, the issue is to remember to do this.
What I'm seeking, then, is a toggle that automates the process, that invokes WiFi only when logged in to WiFi, but that restores full cellular when one is no longer on WiFi (typically through having moved out of range of the WiFi network).
I do not think that this would require much programming, merely the addition of a switch (probably on the SIM page) that would enable it. But I cannot think of a single feature that would be more useful to users. It would provide battery savings to everyone, though some more than others.
Thanks for reading this and, if there's a place more appropriate to post it, for directing me there.

Good. So is turning off the phone and putting it in a plastic bag in the fridge. What I'm proposing here is maintaining full functionality of the device while extending the life of a charge by as much as 5 times, without even the slightest performance hit. Actually, that part can already be done; what I'm proposing is a toggle that automates it for those who want it.

I'm very sorry. Apparently my meaning was unclear. This, a switch somewhere in the configuration options, is a feature request that I was making because I think it would benefit AOSP overall, provide economy and convenience, and be something not found elsewhere. I seem to have accidentally asked what program will make a battery last longer while only partially shutting down the device, or what program would be best to kludge together a way of doing this. I apologize for my lack of clarity.
