Lumia 800 (RM-801) high discharge rate - Nokia Lumia 800

Is anyone getting high discharge rate on 12070 firmware? This is driving me nuts, the phone lasts barely 24 hours. The drain value is about 207mA, sometimes drops to 76mA, but after a while peaks again even to 389mA. HD7 after 24 hours has 60% of battery left, Lumia 13%.
If this is the way how Nokia is going to continue with the windows phone brand, then god be with us.
PS: don´t go telling me about hard resetting the phone, I´m not gonna do that, I did, it fixed it, then I restored the data back, and after a week it´s back. I don´t have time to do this every weekend.

Yes and 12072 made it even worse for me, about 100mA when not in use and 350 or higher when a push notification comes in.
I personally think the data connection is causing the big drains, when actively using 3G the battery drains very fast. So using whatsapp, IE9, etc and other apps using data or PN will contribute quite significantly. I am lucky if I get 20 hours, most of the time 12-15... It used to be 20-24 on 12070 somehow.
You can test the battery drains due to PN by sending yourself some messages trough whatsapp (or let a friend do this) and then check the diagnosis app battery meter.
Also a bad 3G reception will kill the phone in 9 hours of use

It´s not a problem of 3G, when I switch to EDGE, I also get drains like that. What I think it is, it happened everytime when some apps got updated, lately SkyDrive and SoundHound and Weather Flow week before. Nokia should do something about this because this is unacceptable.

Are you using 'as items arrive' for the email 'Download new content' setting? I was getting wild and frequent fluctuations from 90-400 mA with this on, changing it to poll every X minutes seems to keep it down in the 70s. Can't be 100% sure if this is the issue without more testing.

Battery life problem related to Radio Rom 1.16?

Good morning!
Over the last week, the battery life on my JASJAM has become totally miserable. I'm just barely getting over the 12-hour mark most days, and this is with very little use, mostly just receiving emails on my desk while I'm sitting at work. The only programs running are ActiveSync and Outlook, as I use Microsoft Direct-Push with my company's Exchange server. I am always connected to 3G in New York City.
Now, this might be due to the usual crappy Cingular 3G issues in New York City. Before this ROM upgrade, in some parts of the city, my phone would constantly turn on as the network was creating some wacky reactions with the phone. Since going to the Cingular-inspired radio ROM, the screen stays off but I have no idea what's going on behind the scenes.
Anyway, do you think my battery problems are ROM related, network related or something else? BTW, I've tried two different batteries and they've both had similar run-down characteristics.
Thanks!
Mine was last loaded 3 days ago and has more than 60% left.
But i've used the phone just some times and only 4 or 45 phone calls.
And NO UMTS!

This is a problem that I have talked about before on other forums. Using 3G on the tytn will shorten your battery life about half compared to using edge. I dont use my tytn for much (a few calls, msn for chatting and email and some browsing) and I can't get more than 10 hours on a charge. When I change it to edge I can get over 24 hours.
Hollywood...
Believe me, I feel your pain. I'm using an extended 1500mah battery right now (which doesn't quite fit perfectly but close enough) and I think it should be good for about 17 hours according to the current calculation with UMTS always connected. That's enough to get me through 1 day, but it's pushing it. Do you think the next HTC rom might show improvements in battery life?
Thanks
hey CNJYC, slightly OT but did you get the Seidio battery or the one from Lionbattery.com?
Sleuth255...
I have the Mugen 1500mah version from Lionbattery.com. It is every so slightly thick which causes the battery cover to bow out maybe a millimeter or two in the middle, really not much at all. I will not go with anything larger that requires a new battery cover, as this defeats the purpose of such a nice, small device. Instead, I carry a spare or two when I'm traveling. Do you know anything about the Seidio battery?
Yeah, it has the same problem. I have a Seidio. I was wondering if the Lion battery fit a bit better.
Got it...thanks
@CJNYC and Sleuth255,
Compare to standard battery, how much more (hours or minutes) do you get from the extended battery?
Maybe 2 hours on 3G
After ur post and continious using of 1.16 radio on mu HTC TyTN for a week now i also feeling that the radio seems drain battry fast....the situation is that i generelly receive/made 10-15 call a day of total 1 hour or so duration....30-40 min of game play and may be more less 10-20 min of chatting and browsing in my tytn and i can get upto 2 days easily with 20-30 % of battry life left in gsm 900 mode ooo and always pushmail activated and of avarage 8-10 e-mail receiving and sending...
but after 1.16 radio i thnk i can go upto 1.5 days with same battry left and the senerio is the same regerding my usage pattern....and most of all before that the battry used to discharged 10% overnight at maximum when i was sleeping with 2-3 mail receiving through pushmail and of course no other use...but now it seems im loosing 20% on same time period...
i think i need to do some more testing regarding this battry life probs...any other feedback is really wanted...
thanks
Sajib...
Thanks for your posting. The 25% reduction since going to the 1.16 ROM that you reported is basically exactly the reduction I'm seeing here on 3G in NYC. Everything else about the ROM is better, especially how it handles weak signals and not forcing the screen on, but if I can't get a full day out of it I will probably downgrade. I'm just holding out for a new HTC ROM, but I'm not sure I can wait any longer.
Any other experiences with the 1.16 Radio ROM?
Thanks!
I have some problem... Dunno is because of 1.16 Radio ROM or my application. But i did Hard Reset & Install bk the Application that i use previously. The problem still same...
Let say i didn't touch my phone (Button) for about 30min and more. The phone will like go to Searching Mode.....wat i did is turn to FLIGHT MODE, then OFF the FLIGHT MODE. Then the phone only will get the service provider. After that it's ok. ...
Anyone encouter this problem b4?

[Q] Mozart battery life

Hi!
How long does your Mozart work.
My settings: WiFi & BT are off / Exchange sync is permanent.
Around 30 mins calling time a day.
Battery is empty during the afternoon. It simply does not "survive the day" and has to be recharded. Is my device not ok, or do you have the same experience?

Are you on telstra network perhaps?
I read something on the internet about a bug in the Exchange service, it reestablishes the connection every minute, so thats why you battery is empty so fast. (probably)
HTC is working on the problem. but if you are on a Telstra network there is a workaround http://blog.walshie.me/2010/11/15/htc-mozart-telstrabattery-issues-solved/
Hope this helps
I was not too pleased about the battery myself, but it was never as bad as what you're reporting!
I've always had Wifi turned on and use Exchange email... and have been continuously using the media player or an app or game now and then... and it lasts me a full day... There was once or twice when i had been continuously at it that it had 20% left by evening...
I posted about it on the forums too and someone said it'll automatically adjust itself... i was a bit skeptical, but today it still has 60% battery left and it is 12:15 AM now...! (though i did have Wifi turned off for the most part today)
Hello everyone
I have the htc mozart one month offered by the girlfriend. I used the mobile phone several times and even with wifi and bluetooth on and always lasted one day (24h) without problems. yesterday charged at 24h and at 15h had no battery. had not even turned on wifi or bluetooth. since then the battery does not last anything I do not know what happened but its not and nomal. Somebody now something about? This its really a joke but I know that the battery lasts well over

were you in an area with poor cell reception? if yes, that would affect the battery because the phone is constantly working to maintain a signal. i'm using an 1800 mAh battery from Mugen and it's easily lasting 32+ hours with 1 Push Exchange account, BT/Wifi off, 2 POP accounts (1 hour retrieval times) and about 40-80 minutes of calls when i'm in an area with a strong signal. i spent two weeks at a client site where i could barely get 1 Bar (and most often had "No Service) and the same battery would be depleted in about 18 hours. when working in an area with great cell reception, battery life is great for my use. on 2 occasions i forgot to charge the phone overnight and had about 15% battery left when i woke the next morning. in case you're wondering, i'm using the HTC TestTool - Battery Tool (v1.20.0.0) to determine battery percentage. you can find in in the WP7 forums.
I'm using the phone as I have always used but something happened that makes the battery last while. without stirring overnight stays with half in morning
i leave in portugal and use optimus

That the point you living in area where the cell phone reception is really bad!! It's same for me when I go to my Island in carraibe !!But where I living Paris and London I can keep the battry 100% at 7h in the morning till late in evening around 2h at 20%; Using all day Wifi, TV, Game... So the issue about battery is not the phone but carrier issue.
Because when I take a "Metro" or "Tube" where the reception are really bad my battery drainning fast....
For me it last for a day, since i don use 3g n wifi, i use followin settings.
3g turned off
wifi turned off
Always try to close the running apps using the back key.
everynite i switch my phone to low brightness, so that i don need much time in charging my phone in the morning b4 i leave to work.
with every settings turned on the battery last for 15-17 hours.
hope they fix the battery issue in the comming update.
With heavy usage 9-10 hours battery life for me.3g,4 e-mail account.One is push,the others checking every 15 minutes(almost getting 150 e-mails every day).1 hour talk time,Web browsing over 3G,listening music 30-45 mins,playing games 15 mins.(Brighness medium,location service all on)
using dark back grounds will help save power, but everyone nows that dont they.
Except it won't help with Mozart. It only works for AMOLED displays, Mozart has an LCD.
it has at least awesome standby time...
the red light once began to flash when i went to sleep.
when i got up around 9-10h later the phone was still on.
only bluetooth was off...
even more standby power, im back to report:
3+ DAY STANDBY!
i charged my phone friday 02-11-2011
untill today (tuesday) it still lasted,
same-time as last-charge 02-15-2011
thats incredible 4 days...
WLAN was OFF the most time
3G on
only did around 4-7 2min calls
didnt play much with it,
only quickly checking for news in market from time to time
had 2 reboots because of that
and did around 5 pictures.
i think its pretty awesome times...
yeah with heavy usage its only 1 day
but still its a phone and its standby is great
There's no surprise that the phone lasts long when you don't do anything with it.
As far as I can see, the battery annihilating combination is browsing the web via 3G. Guess IE was optimized for speed to impress with responsiveness. This probably won't change much until IE9 comes (which may or may not help). The power-hungry screens are a universal problem on all current HTC devices, with WP7 and Android equally, so this won't change.
The real killer is WI-FI, i upgraded to the MUGUN 1800MiH Battery, and im not looking back, it lasts way more than 50% longer than the standard battery did.
for £28 with free delivery, you'd be silly not to buy it.
also, as an aside, the Battery arrived within 4 days from HONGKONG, which is great because it advertised that the battery would have a 10 - 15 day shipping time.
Okay... what if
had 50% power left the night before...
after 6 hours sleep
phone is out of battery @@
Now that aint right, im guessing something is running under locked screen and iono what!!! but i always jump out of any program when im about to sleep too, so it cant be because of that
In the past, i could have standby time for a long period especially after one night. But the past two days when i woke up, it always ran out of battery!!
the first two days when i got my mozart it died on me due to low battery. but when i upgraded it to nodo(i think), the battery is longer now. but i will check some more.
my battery usually lasts 24 hours. But when I open htc weather, starts to pick up GPS signal if I leave soon have a very abnormal wear of the battery.
I tried with other Porgram gps and the same happens, the battery does not last 10h

[Q]Real world battery life

When someone here gets one of these could they please let us know what the battery life is like?
I know nokia says 400 hours standby but standby figures are kinda plucked out of the air since smart phones, i'm sure mine has 200h plus but realistically 2g, everthing turned off I can get around 4 days use of it when only using it for calls/txts. I nreal world upto 2 days, 1 day if I use it a lot.
I know its not real world use, but sometimes when i'm away in area's with no access to a charger I like to know I can last a couple of days without it dieing on me!
Cnet claims that it drops to 25% after just 4 hours of heavy usage. If this is true I would never buy it and it would be a real shame. Lumia 800 had same issues many months after launch and even after numerous software updates it is still not up there.Working at Nokia so I've seen my fair share of lumia failure...Really hope the 920 delivers.

Was that test with 4g on? i'm assuming with 4g it constantly searches for the network. If simply turning 4g off gives a nice boost to battery i'll be happy with that, personally i'm fine 90% of the time with 2g speeds.
My current phone gets just under 2 hours use in navigon at full charge. I know generally you have a car charger in car, but its the only way generally I use to measure how long the battery lasts.
I remember my first smart phone would power tomtom for around 5 hours on one charge, sure the screen was smaller and the processor was slower, but it was still perfectly usable. I suppose 320x240 would feel very wierd now tho...

Is this really that bad? Because this would mean you'll get about 8 hours with half the battery on heavy usage (assuming linear discharging). I'd think that is pretty good.
I currently own Samsung Focus (1st Gen) and I get about 26 hrs or so on moderate to low usage.
Unless they mean 4 hours straight gaming or watching a movie that is a lie.
I've had my phone for 6 hours using it pretty much none stop. Downloading lots, taking pictures/video, trying maps/gps, wifi on but not connected, no LTE but "4g", placed a few calls, dozens of text, full settings/setup, etc etc. This was from the phone coming out of the box at ~50% charged and I am at 19%.
Just got it so I will report back in a few days and see how it goes.
I've had mine for a week now and I have to say Im a heavy user - maybe because of that Im not too happy with the battery. I have to charge it after 7 or 8 hours but I do have bluetooth on, wifi on, 3g on, push email, facebook updates etc on all the time. As an Ipad owner I thought it might be on a par with that for battery life but it isnt....
I use my phones enough that I am use to charging them every day. I have yet to have a smart phone that would last me 2 days. This phone so far fits right in there, no worse no better. Haven't had it long enough to be a final decision though.
Yesterday I had it unplugged from 7am to 11:30pm and it was at 29%. This was with wifi off, BT off. Lots of usage, played a bunch of Angry Birds:SW, lots of texts/app downloads/heavy camera usage/etc...
In the end unless it makes it to the next morning at above ~55% it really doesn't matter, I'm going to have to charge it. All that matters to me is that i can make it through a day and so far this phone seems like it will be able to do that no problem. If you spent a heavy day of gaming and movies I suspect you would find yourself needing to charge again but that is inline with every other smartphone on the market unfortunately.
I've had the phone 72 hrs now. I previously had the 900, Focus S. I run my phone with bt, and WiFi on. I do not turn off lte or 4g. If the phone charge lasts from 6am till 330, then its good for me.
As with many new phones battery life in the first few weeks is not really accurate. Currently my 920 exhibits the same traits the 900 did.
I do light music and games, heavy internet and social contact, medium texting, but virtually no phone calls. As of now, this puts me in the 40-50% range. I expect it will get better as I stop experimenting with themes, lock screens and tile arrangements.
I've been able to use the Lumia 920 for one full day now and this is my battery information:
The information i'm about to put out is with; text messaging, internet, couple of phone calls, 15 minute gameplay, more surfing the internet
The battery information can be found ' Settings -> Battery Saver -> Battery Info '
Battery info:
Remaining battery life: 47%
Estimated time remaining: 3 days 3 hours (obviously meaning standby time)
Time since last charge: 20 hours
I took the phone off the charger at around 10pm last night and haven't used the charger since then.
My battery drains real fast. I think its down to 2 reasons: 1.data connection speed is set to 4G. 2.Loads of background apps running.
I dont have 4G in my area so the phone is swithing to 3G sometimes even poor 3G signal which makes it go to 2G. so if its constantly switching network signals that will drain battery fast. my Lumia has no option to keep it only on 2G, but i can change to 3G or 4G. If i could change it to 2G i guess the battery would last all day with no problems.
turning off background apps can also help reduce battery consumption.
btw i have a Lumia 920 bought from Phones4u using a TMobileUK sim
Ive had the 920 from the MS Build conference for a few weeks now.
1. I turned off NFC (tap to send). No need for it.
2. I turned off Bluetooth, unless I actually need it.
3. I ride the train for an hour to work, and an hour home, and use the internet sharing pretty much the whole way with my Surface.
4. I have it set to pull email from 3 different accounts, with it set to get items as they arrive, and I get a lot of email throughout the day.
5. The area I live in is all LTE.
6. I leave wifi turned on all the time, as I have it at home and at work.
7. I make a few calls during the day each day, but maybe only 20 or 30 total minutes at most.
I've found the battery life after a few weeks now to be excellent. Even after an hour of internet sharing on the train, it has only used 7% of the battery. Battery life seemed shorter during the first week or two, so i'm guessing everyone else will have similar results as the batteries get conditioned. I haven't had a problem with it running out of power before the end of the day. Early on it did, but it has gotten much better,

After a week, today , this is what I see also. My phone comes off the charger when full, last night it was 11:15pm. The charge sits at 85% with 40 hrs estimated time remaining.
I have BT, WiFi, Tap to Send on. I have gone into background tasks and blocked anything I don't want running. I have noticed that Nokia Drive+BETA, when on, really drains the battery, as does streaming from XBOX Music Cloud. So Nokia drive is blocked in background tasks and I do have Cloud Music turned off.
I drained the battery to under 10% last night....I'll try to push it tonight to get further.
But overall, I'm happy with the battery. I know I have some wiggle room with turning off BT and Tap to Send if I want.
Another day, another test.

I hope they allow that in a future update, when I know im going to be away from a charger for a while I always switch mine to 2g to get that extra bit of juice
I did cave and order a 920, t-mobile offered a silly retention deal, was going to get the 820 but for the price i thought why not!
Have had mine for almost 8 days now, same here. My battery life is excellent. I keep wifi/bt off unless in use. No LTE here.
I played Drag Race for a good 2 hours yesterday on top of texting a bunch, few pictures, normal browsing/FB/etc...
When I "plugged in" to go to bed I was still over 50%. (5:30am to 11pm)

[Q] Battery Life?

So how about the battery in the Lumia 920.
After the Lumia 800 failed in this area it would be great to know if the 2000mA battery is big enough for this whole Thing

I've been using it for half a week now and battery is phenomenal even in LTE all the time. Will last you a full day off not a day and a half with moderate use. Full day heavy use probably.
You have nothing to worry about this time. Nokia got it right.
More details here: http://forums.wpcentral.com/showthread.php?t=200158
Mine sucks right now. I'm just using it for normal email updates and a few downloads from the app store and it'll be on 40% by 4-5pm. I've turned off a lot of the background updates on the live tiles too, but it's not making a difference.
Screen on time is disappointing.
Mine has excellent battery life. 2 days on a row on my last charge.
Ppl with battery life problems, I would suggest to visit the Nokia support forum.
Important
If you disable NFC (tap+send in settings) you have a HUGE improvement in battery life.
As mentioned above, disabling NFC and background apps will greatly improve battery life. I am more than satisfied.
I leave my data connection on 2G most of the day and it seems make the phone last all day, with heavy use. If I really need the faster connection I switch it to 3G. This seems to work for me
Full day, 3G use (using on a 3G only carrier, no LTE unfortunately). Moderate-to-heavy usage, not a problem getting back home, chilling on the sofa, doing what not, and having enough battery to last until bed time. FYI my day starts around 8-9 and I head to bed around 11ish+.
I hear battery life isn't as good when NFC is on. Don't know though, I never have NFC on anyways (really don't see how useful it is atm).
Battery saving Tips
This battery saving tip has been overlooked since WP7 first generation devices. The reason why some ppl will be having huge battery drain is due to apps running in the background. So, you need to think about the apps that you actually need to run in the background. Make sure all your email accounts are on the highest interval time to be checked and/or "as the item arrives". When you select as the item arrives I believe true push is being used which if you don't receive tons of emails will save battery in the end. The other apps settings are located here start screen>settings>swipe over to applications>background tasks>and block all apps that you can that don't need to be running background tasks. I for instance only have accuWeather app running background tasks. Another thing is you need to be aware of apps power usage...i noticed that accuWeather is far better at using less power consumption than the Weather channel app. Other tips are common knowledge. Disable NFC, use WIFI when available, turn off high sensitivity if you're not needing it, use low time-out for shutting off display and use low brightness. Be efficient!!
Good
Lasts me about 1hr for each 10% increment. About the same i was getting with the S3. While playing music its battery life seems to last longer than leaving it on standby :S Find standby kills battery some reason, just recently turned of nokia drive background app, hopefully that makes it last longer
Battery life has been excellent for me. Mine was fully charged on Wednesday morning @ 8 AM and was at 48% when I put it on the charger Thursday @ 2 PM with moderate uses. Unexpectedly, the battery life is much better while on the LTE network than when I'm using my SIM card not registered for LTE usage. Standby drain is very very good.

That's because WiFi stays connected when you're streaming music, whereas WiFi disconnects when on standby. Known windows issue that should be addressed by ms soon.

I get great battery life unless I enter into an LTE area. When I do, my phone gets VERY hot and the battery runs down in a few hours. Even if I'm not doing ANYTHING with the phone. Strange...

How do you switch the 920 to 2g mode? I only have 3g and 4g in the options on max speed? my old lg wp let me set either 2g or 3g, huge difference in battery life on that devic.
to be honest tho so far i'm impressed easily outlasts my old phone, just tried turning off the high sensitivity on the touch to see if it makes a difference.
also run down the phone till it turned itself off last night, tried turning it on got the warning icon of low battery, did it again then it started, data connectino wouldn't work battery said 0% remaining and it lasted just under half hour with me playing mirrors edge, makes me wonder how accurate the battery % is
Battery capacity seems to have been cut in half!
When I first got the 920, at 100% the estimated battery life would say 1 day and X hours. Now (2 weeks later) when my battery is at 100%, it now says 13-14 hours of estimated life. My battery also drains much faster now than it did in the first week of owning the 920. My use of the phone has not changed over the last two weeks. I'm always in an LTE area, WiFi on and I use bluetooth from time to time. Is this an issue that other people are experiencing?
I'm trying to figure out if I need to exchange my 920. Any help or advice is much appreciated. Thanks!
i found it was using 2% battery every hour whilst connected to a data connection - but not syncing anything, all backround tasks turned off. This seems a bit mental.
So it seems that battery isn't so good :/ Too bad because i was wondering to buy this phone.

After deep cycling the battery, I am back to the correct reading. I am now losing a little less than 1% of battery life per hour on standby!

Crazy Battery Life on 920

The first week I had my 920 I was lucky if the battery was at or above 40% by 12 noon. The 920 is my 2nd phone line and I am using it mostly to learn WP8, to surf the web some and listen to a lot of podcasts, usually 6+ hours of them a day. The past 4 days the battery in the 920 is showing insane runtimes. It is currently 11:30pm and it has been off the charger since 8:00am, over 15 hours with overs 8 hours of audio podcast listening. The battery is currently reading 61%. I originally got the impression that LTE was killing the battery, but that is no longer the case.
I have a Share Plan with AT&T with 2 phones, a Galaxy Nexus (GSM model from Play Store) and a Lumia 920. I use my Nexus as my main phone line, to access GMail and Google Reader (a lot of Google Reader feeds). The Nexus has been off the charger the same period of time and is showing 41%.
For me wifi destroys my battery for some reason I get 15 hours with wi-fi on or 28 with it off
Interesting, mine will usually run for 24-30 hours before hitting 15%, including regular usage. 4G gives it a whack but generally I find similar to other phones, if low coverage it chews the battery
Reading all the doom and gloom of 4G LTE on various mobile phones, after my 1st weeks experience, I was expecting similar results going forward. But, after 2 weeks of use, the battery falls in line with the results you mention. And, with that I am not complaining.
same situation here.
It looks like the phone needs some days to warm up and get long lasting.
Also I see that wp8 is heavly optimized for background task in order to not consume a lot of battery eg: my phone lasts more than 2 days with light usage.
I listen to podcast for many hours and it doesnt affect the battery that much, in fact I'm surprised by it because I know audio playing takes a load on the cpu.
Mine.. overnight without charge or using the phone it drained from 100% down to 35%. BS
Two words: Background tasks.
Make sure you don't have unnecessary background tasks running. I have less than 5 and my battery runs more than 2 days easily.
How do you kill or monitor background tasks?
I had really good battery time of 19 hours the first day of installing the new firmware, then I enabled bluetooth again and it drains like crazy. its hit or miss but people seem to think that whatsapp drains battery. I personally would like to disable LTE (its really slow in my area) and just keep bluetooth that seems to give me 12+ hrs of battery.

You can block background tasks for 3rd party apps in Settings->Applications tab->Background tasks. There is no way to monitor these tasks because WP OS doesn't offer any such capability.
Unfortunately there is no easy way to block 1st party apps and if they are misbehaving (like sync something over and over), there is nothing you can do about it.
Turn on Battery Saver can also effectively kill all background tasks. But that's draconian. I still would like my smartphone do something in the background for me.
Don't forget, the biggest battery drain factor could be your cell phone signal. If you keep the phone in a fringe area, the cell radio will drain your battery very quickly while try to maintain communications with cell towers. This is outside the OS and you can't do anything about it.
I had a weird battery drain the day after the last upgrade. No apps running in the background BAR the movie that i had paused.. I lost 80% without using the phone in a 6 hour period (post charging). After a reboot it seems ok. Perhaps i should pause another movie to see if it happens again....
I must say that I have mine 2 days and the battery drains too fast... I dont know what to do .. Maybe because its new ? Some one can help me maybe ?

don't judge a phone's battery life until a week later.

in wp8 is 2 weeks later
My battery is pretty inconsistent. MOST of the time it's awesome, and will last like 20-25 hours without needing to charge, but that just makes it especially jarring when every now and then I go to check my phone at 4 in the afternoon and it's at critical, and I have no idea what causes it.
Plus when it does die I have to put it on the charger for like 2 hours before it will let me turn it on.
I found interesting point in the battery life today, if the screen is off, the battery drain is in the range of 3-4% which is good, however, if the screen goes on the battery drops like 15% in just 25 minutes. After thinking I tried to set the screen sensitivity to normal and it solved my problem. I kept the screen on for more than 45 minutes and the battery went down almost 6% only which is good. I still have to test more to give a concrete evidence.

I usually run a battery discharge app Saturday night. Then a full recharge with the phone off. That usually gives me dependable battery life of about 12 hours a day for the entire week. If I forget and not run the discharger I notice it midways into the week when I only get about 8 hours out of it.
AT&T lumia920:
after updating my phone to the 1314 update, my battery life got worse.
I went from 14 hours per day to only 8 hours.
thanks nokia -_-
note: I was not experiencing any connectivity issues on my phone.
let's see how many people here actually have NFC on and Auto-Brightness on... lol
I used the sleep app last night after charging to 100%, and then I fell asleep with it on.
I woke up to find the sounds still going, and when I checked my phone worried that I killed the charge, I found it still had 92% left. That's impressive.
