My battery life seems far too short. If I remove my phone from charge at 6am it's got very little life left by 10pm. 16 hours is pretty poor... No WiFi or BT, but I do have reasonably high usage of around 15-20% perhaps.
I did read something about Quick Calendar being a bit of a drain, but I really like this widget, so I don't really want to lose it.
I don't have all that many apps installed, maybe 10-15. How does this battery life compare to everyone elses? Is there anything I can do to extend it?
mine last about the same. I am using the internet alot & widgets like twitter & flickr as well as watching films/listening to music. To be honest I think that this battery is pretty good seeing as how much I use.
When I compare this to my Diamond which i was using a lil bit less by way of features I am truly impressed with the stamina they have given to the stock battery.
That being said if they ever release an extended battery I will be buying that in a heart beat
Generally I think it has decent battery life, but its changeable. Sometimes I wake up in the morning and the battery has drained overnight from nearly full to totally empty, but sometimes there is no indicated overnight drain based on the battery meter.
I think the battery meter is probably about as accurate as the one on my Diamond (ie not accurate at all)! I get the same battery life from my Hero if not more as I did on my Diamond with the extended battery which considering I do a lot more with my Hero is impressive.
I think the battery is pretty good considering all it's doing.
When I have it on, playing mp3s and HSDPA and wifi all day, I'm lucky to get 12 hours. I mean literally MP3s all day though, and since I'm at work having a usb cable into my laptop isn't a big problem, which removes the battery problem.
Today I've had limited internet use (mostly just 2g email polling, with about 30 minutes of whatever 3g exists in the bowels of wiltshire) and, as I've just noticed about 3 hours of GPS. It says it's used about a quarter of it's battery. Used as a simple phone, I'm sure it would last more than 3 days, but why bother?. As a pure email device, maybe just under 2, and as an always racing internet/music/gps beasty 1 day.
I'm happy with it.
Have you tried intstalling taskiller to get rid of those apps using power in the background?
My battery life is terrible. I fully charged my hero and unpluged it 8 hours ago. Since then i've made 10 minutes of calls, around 45 minutes of browsing (with 15 minutes using wifi), and 'played' about with it for around 30 minutes. My battery is down to 20%. I don't think this is good at all because i haven't used it that much.
edit: I also use taskiller to close apps after im finished with them.
Yeah, I use taskiller, nice app. I've also installed something called Power Manager v1.5.9 but I'm not really sure how it helps... if it does...
Woah I started doing a Battery Saving /Speed up Tips thread last night - Just posted it - Any good stuff post on there... Plus there might be stuff you've not done yet (Tho its pretty straightforward stuff that I reckon you'll have done already Ya never know tho)
Dayz xx
I found the first 3 charges only gave me a day (but this was when hammering the phone for the first few days), after the 4th charge and dropping to my normal useage i get 2 - 3 days, which is just better than my Tytn2.
I use my hero as my works phone and make about 40 minutes of phone calls on a 12 hour shift, it also picks up my emails and does about 30 minutes of browsing during that time, and by the time i get home it has about 30% of battery left which isn't too bad, and is much better than my diamond.
Things seem to be improving for me too now. Also, I took of Quick Calendar which people were suggesting was eating battery...
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
I just received my Rezound new yesterday, downloaded some apps from the market, and set everything up for normal use today. I got it off the charger this morning around 7:30am at 100% and its dead at 4:30pm. I would consider my use light today as I only used the web for maybe 10 minutes. I mostly did things like add contact shortcuts to my home screens and move icons around, and download maybe 2 new apps.
I came from a Droid 2 which got pretty awesome battery life running Liberty 3 and I'm wondering if my usage time is normal.
Total Time 8h 22m 33s
Display 80% (Time on 2h 45m)
Call Stand 5%
Phone Idle (Time on 5h 37m)
Android System 3%
Dolphin Browser 2%
Android OS 2%
Wi-Fi 2% (Time on 1h 38m)(I don't believe I was connected to any networks though)
Drop box 2%
The screen is what kills it along with LTE. If your screen was on for 2:45 that is why. The display sucks battery on this phone.
Thanks for the reply, I figured that was the case, but I still thought I would have gotten a little longer. I hope a custom ROM will help some with the battery life.
I am on stock rooted and don't really have battery issues. Typically I get 12-14 hours which by then I have easy access to power. If it is going to be a long day, I use the extended battery. It is not uncommon to still have charge left going into late at night.
I have the screen less than a third of the way on the selector and have Auto brightness turned off. Screen timeout is set to 1m but when I set the phone down, I have a widget called ScreenOff that I click to blank the screen. Primary reason for doing that is so I don't accidentally enter some app, but a secondary is that it turns off the screen before it would normally timeout.
When I am at home or at work, I use WiFi almost 100% of the time which due to strong WiFi signals there, (for me) uses less battery power than LTE.
Otherwise, I have LTE on.
Right now today, I am about 50% with 9h 12m of use. I fully charge nightly with the AC charger on my night stand so when I get up it is 100%.
I have an extended battery, but normally use the stock battery unless I know I am going to be away from the office for long periods of time.
I am not much of a game player, but I do watch short videos from time to time. I have streamed music, but don't normally. I get 10-20 calls a day typically and use my browser on a regular basis (reddit as well).
The camera is Awesome!
Unless your display was on max brightness and you were streaming HD movies. That's bad battery life. I get 2 times that even with autobrightness, maybe your battery isn't broken in yet
A good measure is 30minutes display time per 10%, and 1% per hour with 3G and normal sync scheduling... If your apps sync ever 15 minutes that will kill it, and 4G should kill it a little more than just 3G... Minor fluctuations are still OK, but you shouldn't have 15 minutes per 10% unless everything is basically on full blast
My battery life using the setup in my sig is usually very good.
I can easily make it through a normal workday listening to mp3s from my card/texting etc using the standard battery. My screen is set to 30%, screen timeout to 30 seconds.
I do like to stream audio however using iheart radio or Sirius radio online. If I do that, I'm lucky if I make it 4 hours on the standard battery (without ever turning the screen on) When I am going to do that, I use the extended battery and keep a 2nd one in my pocket. I have two external chargers I use so I always have spare fully charged batts.
I actually prefer the feel/weight of the phone with the extended battery and the HTCPedia cutout hard rubber case.. That gives me a better grip on the phone and I barely notice the weight difference when it is in a Jean pocket.
I guess it just depends on the actual phone itself. My phone charges everynight. I pull it off the charger at 6 am and by 10am the battery is dead. I have 3 batterys, and a wall charger that I carry around. I don't consider myself a heavy user either. No music or videos. Only text, gtalk, gmail and a phone phone calls that last a few min each. I only have google and exchage set to push. My 2 yahoo accts sync every 4 hours. I do have fecebook as well. Screen is very dim. This was all using rooted cleanrom.
I am now back to bone stock, with a CLNR phone that just arrived yesterday (due to connection problems with my computer) So maybe a stock rom unrooted will make a difference. Heres hoping!
Sad.....great phone, I love it!

This. I was playing "draw something " with friends today at work and even with a fully charged extended battery it only lasted about 3.5 hours with the backlight at 100% and oc'd to 1.7 GHz. But that was constant usage for those three hours.

That game literally jumps out of your phone, and rips your battery in half. But its way too fun.

Diff. Roms equal diff results for me. All of the ICS roms I've tried all keep my phone up time and awake time the same. Is anyone else having this issue? Due to this, I typically end up getting around 5 hours of life even if I leave my phone off for the duration of that time. It's annoying because I really want to stay on ICS but get double the battery life out of the GB Roms.

On Scotts CleanRom 3.6, with fairly heavy usage (hour of solitaire, hour of browsing xda, texting, 30 minutes of phone calls) I can get about 10 hours before needing a charge again. Before I updated to 3.6, which has the 3.8v battery fix, I could only get about 5 or 6 hours of similar usage. I don't recall if prior versions had my awake and up times the same, but I haven't noticed it recently.

I take it you don't stream audio like I do??
I just got my Rezound yesterday, and have noticed a surprisingly poor battery life. I did all my setup yesterday, and fully charged the battery over night. After unplugging it this morning, I listened to music off the sd card for about 45 min, browsed the net for about another 45, then stopped using it for a while. I noticed the battery was about halfway through, so I plugged it in to my car charger and did some more Internet stuff. However, after checking the battery info, I realized that even plugged in to the car charger it was consuming more power than it was taking in. I finally had to turn it completely off and let it charge to get the battery from yellow back to green.
This is the same charger I used for my Droid X, so I know that it is working...

I've been running BAMF ICS v0.9 for a few days, and the other versions before that. I get 12-14 hours with 4G on, and 20-23 with 4G off....I keep the screen on 40% brightness
Watch your clock speeds if you are on ICS. They constantly Max out, both cores. That's where your battery life is going.
Sometimes data flickers for me on random days, that's the only thing that wears my battery down fast. But I can still go through the day have 40ish percent left. If it doesn't flicker I can go through through day with about 50% left. And if in on Wi-Fi most of the time I have nore than that left over. And that's with using the phone for a couple of hours with the display on.
Trying ineffabilis with DSBs 1.1.3 kernel and undervolt it some
for me, battery life killers can be streaming audio (sirius xm or espn radio) and definitely jelly wars. Phone will die on extended battery in about 4 hours of continuous play.
Otherwise, normal usage, I get 10-16 hours of use on my extended battery before swapping it out (use 2 extended batteries).
4g definitely runs the phone hotter than wifi (about 20 degrees hotter for me)
The only time my phone gets around 95 degrees is if it's on a charger and I'm watching a movie, and it takes about an hour for it to feel warm, which could even be caused from me holding it the whole time. 4G doesn't get my phone any hotter than 3G Or Wi-Fi. Guess every phone is different though. least we get signal xD

KORM via the beast known as the Rezound.
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.

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!
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.

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.

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.
