and i turned it of. do u use your facebook account ? maybe its that whats taking lot of energy
[Windows Phone 8 General] go0gle:
Is there an app that would let you see the actual battery usage in real time ? That way we can see the idle usage in terms of mA ..

I have it on my Symbian devices, and I know its possible on android..

My EKA2 device idles at around 8mA with couple of system apps open and Wi-Fi turned off, it will be really nice to know the idle usage in WP8.

I've been using the 810 for a couple days and the battery life is great. No drain issues what so ever. Off line navigation is great for battery saving.
[Windows Phone 8 General] Narathan:
Got my HTC 8x two days now. Here's roughly my set-up:

- two e-mail accounts with 30 minute sync interval

- 3 calendars syncing along with contacts

- Whatsapp

- IM+ Pro (2 accounts)

- Facebook

- Skype

- Cloudy Box

- lots of live tiles actually

- Locations on!

- Weather app off HTC

Note: I've disabled the backup options.

On the first day I got around 6 hours usage and the phone begged for juice. I silently weeped, then remembered I had to factory reset my Dell Venue Pro to fix the drain, and behold...

On the second day (today) I'm 8 hours in and I'm down to 69% only! Same usage, if not a bit more.

Now I'm not sure if this is just pure luck, but since I had a GNex (replaced the DVP), I was used to an average of 8 hours tops, this blows my Nexus out of the water - and that with 200 mAh less! (I used the extended battery)

Don't use kik... It's a huge culprit.
[Windows Phone 8 General] theguitarman94:
Awesome thanks for the tips, tricks and general info about your phones battery lifes. Keep them coming! So Narathan is windows phone 8 worth it? I'm considering selling my 8x without opening it and getting a One x
[Windows Phone 8 General] Narathan:
I like it, 10 hours of medium/heavy usage now and down to 62% but this was a pretty heavy day, I can tell the battery keeps getting better.

And if it's worth it, thats something personal man! :o For me, it was actually needed because my Android couldn't work with some of the settings we use at Uni and it was getting sluggish with 4,2 update, but I really like the stability and especially the speed of WP8! So if you don't mind having a little less customization and just want a fast, solid device, WP8 is interesting alright. But if you like to customize your phone and just use it for private use, the One x might be better maybe... But thats a question only you can answer yourself I'm afraid. I'm keeping my Android as a back up, but I don't see myself going to miss the OS anytime soon :D
[Windows Phone 8 General] gmfeld:
I think my battery drain is now getting worse over time. I'm on day 9. Today, my battery came off overnight charge around 6:30 a.m., it is now 11:32 a.m. and I am already at 68% with very little usage. No calls, Outlook emails come through, a little bit of reading the morning paper on IE. Bluetooth is always on, WiFi is off, tap and send is off. Using the FB app as my background in lock-screen. And I've been closing apps using the back button.

That seems like a lot of battery drain to me.
[Windows Phone 8 General] blackofe:
i've turned on everything on my nokia 920: bluetooth, wi-fi, gps, nfc, and started watching its battery consuming. after 30 hours on 6% i put it to charge. in this time i was playing with the phone a lot and downloaded USA all states nokia maps (2.5Gb).

i'm going to turn nfc and wi-fi off and check it again.
[Windows Phone 8 General] Manafest:
u guys kidding me ?!

I just use WhatsApp and one mail account and i cant hit even the 8hour wihtout to lose all my battery.

I dont know what u understand under "heavy" usage, but for me its normal usage. For example every 15-20 mins a WhatsApp message, and every 40-50 mins i read some news for five minutes. I´m listening to my music 40 mins every morning and i coming home at 15:00 (3pm) and i have 30%. Its not good on my Lumia 920, my SII has a better performance.... and i´´m always on 2G mobile data... -.-
[Windows Phone 8 General] bkaul:
I'm definitely seeing a big difference based on app usage. Haven't narrowed it down entirely to specific apps yet, but a reboot (to kill all background tasks) and taking care to exit out of certain apps (e.g. Drive) has almost eliminated the battery drain issue for me. I do notice pretty significant heating and battery drain if I play games, though.

I've seen reports of some people correlating Gmail's screwy IMAP implementation to battery drain issues with syncing too, but haven't delved into that possibility myself - my main account isn't Gmail.
[Windows Phone 8 General] Manafest:
that sounds wired to me...... but okay, i´ll give outlook a try and lets see what happens, but to be hones GMail is the best. Didn´t try other services... any suggestions ?
[Windows Phone 8 General] bkaul:
I haven't tried playing around with Gmail settings myself; I have an account, but it's not my main one and I only have it checking like once an hour rather than "as items arrive" etc. Google is known for using nonstandard implementations of both IMAP and EAS though, and several times in the past year, they have apparently sabotaged functionality of Gmail on Windows Phones (whether intentionally or inadvertently). For example, up until about 4 months ago, interactions with calender invites worked fine. Then they changed something, and creating an event in a Google calendar from a Windows Phone and trying to add attendees to it doesn't send out an invite any longer. Not sure why ... something changed on the server and it affects both my wife's account and mine, on different phones (fortunately, Microsoft just added the Rooms feature to WP8, so we have a shared calendar there now to use instead.)

The battery life & e-mail sync correlation isn't entirely unprecedented either - there was a big issue along the same lines with Yahoo! accounts and battery life a while back, I think with the first generation of WP7. (Turned out to affect not just WP but iOS too at some level - was due to nonstandard mail server behavior on Yahoo's end)... I think MS patched to work around it in later versions. Likely they'll try to do the same to stay ahead of Gmail's bugginess in a future update if it turns out to actually be the problem. In the meantime, setting Gmail to only sync at specified time intervals might be something to try if that is an issue for you.

As for other services, I use outlook.com to host my own e-mail (e.g. me@mydomain.com); its features and integration as Microsoft Account are great - I actually prefer its web UI to Gmail's (especially when you tie in Skydrive and the like), and it seems to do a better job on "greymail" filtering (e.g. newsletters and the like that aren't actually SPAM). It does a much better job on compatibility with EAS push notifications, etc. on the phone. Can set it up with a new @outlook.com or @live.com or @hotmail.com account or with an existing domain name you own.
[Windows Phone 8 General] Manafest:
thanks very mutch, i´ll give live.com or outlook a try. Is it possible to transfer my WP Phone to an outlook account ?

Its hard to me to switch to Outlook, but i´ll give myself a try. I was using GMail for years and i got a lots of Mails, many of thos from my ex-girlfriends and of old firends.
[Windows Phone 8 General] Narathan:
HTC 8x: yesterday I got 15 hours of usage out of my battery and it was down to 13% when I plugged it back in.

I roughly used whatsapp throughout the day for group chats (projects), made some phone calls, checked my agenda's every hour (Uni), did some browsing, about 2 hours... Then listened to music for 4 hours, wrote some stuff on the Office app, synced with dropbox a few times, watched a few youtube vids and snapped some photo's.

Thats some pretty heavy usage for me in any case. I do have very good coverage, maybe thats helping a bit. I use gmail, outlook and exchange, no drain from them (well, abnormal drain)

I'm not sure why people get such weird results. Have you tried factory resetting the phone? I did that the moment I got my phone. It felt silly, doing a factory reset while the phone wasn't even used yet, but since day 1 I've had amazing battery life.
[Windows Phone 8 General] bkaul:
I'm not sure I'd want to keep old e-mails from ex-es, but that's your call. ;)

If you're thinking of switching providers, this article by Paul Thurrott has some instructions/tips that might help you migrate (click through to the earlier ones he links at the beginning for details):

http://winsupersite.com/windows-live/outlookcom-tip-access-other-email-accounts

(Outlook.com is what used to be called Hotmail.com, before Microsoft reskinned and rebranded it)

If you're really serious about migrating, another thing to do could be to add both the new and old e-mail accounts in a desktop e-mail client (Outlook, Thunderbird, Eudora, whatever), and copy all the old messages from one server to the other. I did that with my old e-mails, calendar events, contacts, and everything when switching service providers.

It's easy enough to set up new e-mail accounts, etc. on WP - just go to settings/e-mail & accounts. Changing the Microsoft Account you're logged into the Store, etc. with requires a factory reset of the phone, and app purchases and the like are tied to the account, not the phone. But, you can keep a Microsoft account that's with an @gmail.com e-mail address and not have it sync e-mail, calendar, contacts, etc. with Google.

If you want to find out if the Google stuff is actually affecting your battery life, you could change the sync setting to "manual" for a day or two and then just manually check your e-mail to see if that makes a difference. I don't know if that's actually a root cause of battery issues for many people or not; have just seen people reporting they thought it was an issue for them. I don't know if it's hurting your battery situation any. My reason for using outlook.com rather than Gmail is partially on the privacy side - I just don't trust Google with my information - and partially that I just personally prefer Microsoft's products, and Microsoft's services work better with Windows Phone than Google's do.

Hope that helps.
[Windows Phone 8 General] Manafest:
thnaks, nice tips.

but my i think u didnt get my message. I already have a @live.com account which is connectet to my WP8 device. And i´ve created a new @outlook.com account and I would like to transfer all my apps which i bought on my @live.com account to my @outlook.com account.

Is that possivle ? And yes, GMail drains my battery, i´ve tested it today... u´re right.
[Windows Phone 8 General] jago25_98:
Somebody needs to replicate the test that was done using a very senstive multimeter and some very careful probes on Android phones (vid on youtube somewhere), but with WP8 phones.

I am hearing reports that WP8 wins on battery, which goes with Nokias reputation.

But I'm interested to know if that's actually the OS itself (Android System Process taking up 2-4% cpu for no use anyone?) or whether it's just stricter on badly behaving apps (no wakelocks, better managed or no true multitasking like iphone).

Better battery could be the Unique Selling Point (killer app) for WP8. No more diagnosing wakelocks and removing CarrierIQ?
[Windows Phone 8 General] richardorchard:
just being connected to a 3g network was causing a drain of 2% per hour. all background processes turned off, no email checking.

This was on a lumia 920. supposed to get 340 hours of 3G on standby. I had reset the phone twice.

2% per hour doing nothing seems a bit much to me.
[Windows Phone 8 General] leventccc:
I bought my lumia today I never charged it to full. It was %60 percent when I bought it. I turned battery saver on(always) and wifi and disabled mobile data,location and nfc. Set brightness to low. Now my phone loses %1 every 5 minutes while screen is on and when I use it. So I think its great.
[Windows Phone 8 General] dnorthington:
I've got an 820 and have good battery life. Low idle drain. Better in both respects than similar Android devices. I've seen plenty of reports from 8X and 920 users who have horrible drain. I think its a software issue that I'm sure they're working now.
[Windows Phone 8 General] bkaul:
Ah sorry, you're right - I misunderstood.

There is presently no means for transfering app purchases from one Microsoft Account to another, and I believe the only way to change what Microsoft Account is associated with your phone for app purchases and the like, once you've initially set it up, is to do a factory reset on the phone and set it up with a different account.
[Windows Phone 8 General] blackofe:
one more time i've made my lumia 920 to dry its battery with turned everything on (LTE, wi-fi, bluetooth, NFC, GPS). it had been working for about 2 days. on 16% i wanted to watch some youtube clips. in some time after that the phone has died, and i couldn't take a screenshot.

after that i've turned wi-fi and NFC off and started watching its battery again. for now it's been working for almost 3 days. here are some screenshots, i was taking during the last days:

i realize, that i haven't been using the phone much - just several phone calls and periodical checking email, weather and some searching with bing voice. however, such a result is more than enough for me. :good:
[Windows Phone 8 General] bkaul:
Actually ... while it is impossible to transfer app purchases from one account to another, it *is* possible to rename your Microsoft Account to use a different e-mail address ... though if the address you want to use already has an account associated with it (i.e. you already created a new account with the new address), this obviously won't work. (I suppose you might be able to rename the latter account to yet another address to free up the desired one, but not sure if there is a waiting period before the address becomes available again)

Caveat: if you rename your Microsoft Account that's associated with your Windows Phone, you'll have to factory-reset the phone and set it up again from scratch to get everything to work correctly.
[Windows Phone 8 General] blackofe:
finally my lumia 920 beeped and said, that "battery is critically low":

well, i'm more than satisfied with the result.
[Windows Phone 8 General] Slai:
My 920 lasts about 1.5 days on average.
[Windows Phone 8 General] Snaqvi91:
How the hell did you manage that?
[Windows Phone 8 General] blackofe:
well, i was just using my nokia 920 as a smartphone, but a game console or a home theater. i don't play (much) on my phone - i have a powerful 3 monitor desktop at home for it, i don't watch movies (just short youtube clips, when it's needed) - watching movies on such a tiny screen could kill my eyes.

several calls a day (i'm not a big phone speaker), emails, FB, short reading, when i stay in line for a cup of DD coffee. this is what i used to use my phone for. of course, i've downloaded nokia maps (2.5Gb for USA), tried noka drive, installed a flashlight and skydrive. of course i feel myself comfortable, knowing, that anytime i can get access to all my online documents and files. of course i'm fine to listen all my music or skype with my parents. but it happens, that i use all these features very very rarely. very rarely. as much rarely as it doesn't impact the phone battery life. much.

i used to use my smartphone as a smartphone should be used for. or what i think a smartphone should be used for. and for these purposes the nokia 920 battery life is more than enough.
[Windows Phone 8 General] muddtt:
My battery life on my 920 is excellent. I usually end up with 50% battery life by the end of the day with moderately heavy use. I have found that certain apps kill the battery. One I've found so far is ESPN Radio. That app sucked battery like a kid on a pixie stick. Even after I exited the app it was still draining it. Since i deleted it everything is back to normal.
[Windows Phone 8 General] Manafest:
lol. i cant even unse my lumia for one day. I have turned NFC, LTE and GPS off. I dont watch any movies, i just listen to music. And not even via stream. I have it ony my davice. I dont use Facebook I just write somethimes with my friends via WhatsApp. I turned Mail Sync off as well.

I dont know how u´re doin this. 1 day for me is like heaven.
[Windows Phone 8 General] nixxor:
I have zero issues with battery life on my Lumia 920. Mine lasts more than a day with moderate usage. I have done some tweaking tho to make it better than default settings would.

Nokia 822

I'm having FANTASTIC battery life with my 822. Literally, I've had it on for 6 hours. Texting, Facebook, etc. I'd say medium usage. I've also noticed at the end of most of my heavy usage days, I'm at around 75%.

It's silly because my Verizon Galaxy Nexus drops down to 90% after less than an hour.
[Windows Phone 8 General] 3clectic:
WOW!! Had the 920 for 12 days and the best I seem to be able to get is about 8 hours with mixed/moderate usage. With heavy usage, i.e. IM, Whatsapp and email for 20 minutes each hour and music playing the whole time, I am lucky to get 4 hours. Am gonna hard reset and see if that makes a difference (as most say whatsapp is a killer, there are a couple that say they don't experience a drain).

There is a WP8 update but hasn't been released in my country yet though.
[Windows Phone 8 General] Higherflight:
Before the latest Skype update my Nokia Lumia 920 would only last only one day with normal usage (FB, about 4 phone calls, some gaming and music listening, 30 minutes on WiFi).

Now, since Skype was updated, I get about 2 and a half days with the same usage.
[Windows Phone 8 General] LudoGris:
Here is a quick survey question for you all and a theory I am testing...

How many of you use the back button to get out of an app and how many just hit the windows button?

Reason I ask is that I think the back button seems to close the apps while the windows button leaves it running in the background (at least the apps that allow fast restart) and may be the cause to drain.

I have just started using the back button recently and noticed improved battery life, though it could be placebo.

In addition, how many of you are letting WiFi stay connected when screen is off? Another theory of mine is that WP8 is not as efficient as Android when leaving WiFi connected and could also be draining battery. Most of us noticed the drop in battery life after Portico and that was one of the major new features.

[Windows Phone 8 General] 3clectic:
I normally use the back button except with Whatsapp (seems if I use the back button with Whatsapp, sometimes I don't get notifications until I open Whatsapp again) or I am purposely multi-tasking (i.e. copy, paste between 2 apps because the contextual options doesn't give me the one I want). I still only really get about a day tops (that's if I don't use the phone). If I use it, that number drops dramatically. Another thing I do, is sporadically during the day, I press and hold the back button and see what's "running" in the background, select the far right window and then start pressing back until I am back to the Homescreen.

For me the battery lasted on 8X and Lumia 920 for 24 Hours on average use and without 3G. I am on edge.
[Windows Phone 8 General] theguitarman94:
Only got my 8x a few days ago and I'm the OP! My battery seems to be lasting about a day and a half on moderate to light use which isn't bad. Power saver mode seems to really help
[Windows Phone 8 General] LudoGris:
So, I realized the back button is changing nothing battery wise. Today I removed the google email access, instead having google forward mail yo my outlook account, and I removed weather flow. Not sire which fixed the issue but I got amazing battery life today. I mean amazing! 20% used with crazy usage (I am at CES) in 10 hours. I am going to put weather flow back on because I don't think that is the issue.

How many of you with bad battery are syncing google or some other POP?

On a Lumina 822 here and the battery life is good, it lasts me all day and then some. My kids were using it for games and Youtube the other day and I still had enough battery life to take pictures, post on Facebook and make phone calls. I just simply charge it over night and it lasts all day.
[Windows Phone 8 General] tboy2000:
I really think there are certain apps that kill battery life. I used to get day and a half stand by reported by battery setting. Now I get something like 15 hours standby or so. I believe its an app. I think I found the culprit. Whatsapp. I uninstalled it and so far standby has gone back up to over a day. Anyone else using whatsapp with poor battery life? Maybe you have excellent battery life. If so are you running whatsapp?
[Windows Phone 8 General] theguitarman94:
1 day 15 hours :)

Moderate use. Dad's been playing with my phone for quite a bit of the day :) Uninstalled skype and enabled the option that keeps wifi on during sleep. I've had the phone a week now so the battery has definitely settled in. I'm extremely pleased with my battery life for a phone with a bright hd screen. Reason I uninstalled skype was because it's still a preview and I believe it makes the phone lag a tiny bit. I've got the 8x by the way
[Windows Phone 8 General] LudoGris:
I have read in many places about the issues with Whatsapp and Skype. Both have caused battery issues. I have found that syncing google was my problem. Ever since I stopped using google on the phone and instead forward it from the server to outlook things have gotten much better. Same with weather flow, but I don't know if that us an issue, I just haven't put it back on. Could carr less about actual temp, just need to look outside to plan.
