I just wanted to post on the XDA forums that there is a thread to help determine what is causing the "heat + battery drain" issue(s) on the Lumia 920.
http://discussions.nokia.com/t5/Nok...n-ATT-Overheats-Battery-Draining/td-p/1606012
Specifically, we've seen fairly normal battery drain when using applications, but when LTE data is introduced the battery continues to drain at a rate of 7-8% per hour even after the applications are closed. For example, streaming something like Xbox Music or Netflix over the LTE connection (wifi OFF), the phone warms up considerably and the battery continues to drain at a high rate even after those applications are closed. The same applications behave normally over 3G or Wifi, and the battery drain is not present afterward.
The "fix" so far appears to be disabling LTE altogether.
• Open Dialer
• Punch in ##3282 and hit Call
• At the Field Test menu, choose more options via the three dots (lower right)
• Select Settings
• Under network type, select "3G only". UMTS should be set to "Automatic".
• Change the "Toggle ENS" setting to OFF
• Back out, power off the phone, and power on again
Definitely interested in hearing other's reports on this issue. Specifically, does this happen with ALL Lumia 920 phones? Is this specific to this particular model phone? Is this a Nokia issue, LTE chip issue, or WP8 issue? Was this introduced with the Portico update?
Thanks.
Upon further testing.........
Disabling LTE is *not* the ultimate fix. Yes, it does help keep the battery drain down to more reasonable levels, but it does not solve the problem. I've subsequently tested with the little brother phone -- the Lumia 820 -- to see if the issue is on all WP8 handsets, on all Lumia phones, or even limited to post-Portico update phones (in other words, did Portico make this issue).
After some thorough testing, I can say with confidence that this issue is specific to the Lumia 920 and not necessarily all WP8 handsets or Lumia phones.
Detailed thread here: http://discussions.nokia.com/t5/Nok...Overheats-Battery-Draining/m-p/1795212#M43837
I am currently working with Nokia to find a long-term resolution to this issue.
Please keep us updated, I'm very interested in knowing how to fix this problem! ??
I found that disabling bluetooth helps out.
Battery drain
To help reduce battery drain I do the following on my WP
I get a connectivity shortcut app. There are a few options available in the store. Anyway I pin airplane mode, Bluetooth, Wi-Fi, and Location on my home screen and turn them off when I'm not using them. Turning off location turns of GPS, so you must enable it before launching Drive/Here. A lot of battery issues I think have to do with the phone being to aggressive (power wise) trying to search for signal. Whether its Wi-Fi a Bluetooth device, etc. I also disable Tap+Send (NFC) because I never use it.
And I go into background tasks and I block every single app from running in the background except the ones I am sure I want to run. Remeber the list where you can block them is for apps that want to run on a timed schedule, they can still run in the BG if you home screen out of them. For me the only one I allow is MS Weather (for the live tile). Disabling Nokia Drive/Here seems to help battery life for some people.
The biggest battery saver I did was forwarding my other email accounts (Gmail & Yahoo!) to Outlook.com, and then set that to only look every 1 hour (instead of the stock 30 minutes). My phone went from lasting 1 - 1.5 days to over 2.5 - 3 days with my typical usage (light usage).
I try not to use Live Tiles, or lock screen pictures unless I really want them (like weather for instance), as they help drain the battery quicker.
Anyway Nokia is really on top of their game so I think they will help contribute to WP to eliminate these issues. The only non-software related issue with the 920 is the dust in the FFC, which personally does not bother me but I could see how it might bother others.
##3282 isn't working for me after yesterday's update. Lets see how I do with the battery today!!!
The earpiece on mine does not work I can't hear anyone and top of phone gets warm I have sent it to nokia repair.

Thanks for the tip!
I also have 5-8% per hour drain. (actual offi. release .1308...)
all off, sync, loaction, WLAN every thing, fresh reboot, phone on my desk, not working with it, about 2 lines H signal.
when i switch to airplane mode....1-2% battery drain over a complete night!
its also no problem to activate airplane mode ON and afterwards WLAN additionally ON, then about 1-4% over a night!
i tried everything i found on the inet.
and i have my white L920 since Dec.12! (i did a "hard" update over PC in Feb. and also the the last release over the air...nothing changed)
so now i'm checking if this works for me and post results
I'm located in AUT with an unlocked, unbranded GER L920.
and we dont have LTE til now...maybee thats the problem..?!

UPDATE:
i solved my battery drain issue by setting my "max network speed" to 2G!
by that i now have a drain of 1-2% p.h.!

That is great. To bad that we whom have received the latest OTA no longer have access to that menu.
really?
I'm on FW 1232.5957.1308.0001
and WPH 8.0.10211.204
I don't need to change the network type within ##3282 menu, also worked for me in normal network settings.

So then how do you set your network speed?
u don't need access to ##3282...its also possible to "limit" within settings/network. (##3282 NOT working within f.e. Rapdialer!!)
I limit it to "2G" only when its more importand to have less battery consumption than inet speed
limited to "2G" in my region it shows me afterwards a "E" on top.
On this PIC i found in the inet is "roaming" deactivated.
I have to activate "roaming" also when I'm within my own network to have inet access (and the "E").
In my town, network operators share their mobile radio transmitters.
I limited direktly at my provider the access to a "real roaming network" for example a swiss network.
Because i'm most of the time near the border
maybee not possible in your version or provider?
I'm on a free GER version.
Definitely trying this tonight.
For the battery drain try light (white) theme. intresting but that help my battery drain problem
Same issue here...Any updates?

My experience is that, I reset the cellphone and after doing this twice and connecting to the internet and waiting for one hour, Microsoft gave me an update for my battery saver and since that time everything is ok, including the battery. I always believed that the updates have problems to be installed completely most of the time, so it's better to reset or download it via the computer and instal it with a cable( using Nokia Software Update). But if it doesn't work, please don't panic. The updates are coming and just be sure that you have reset your device without choosing the setting backup, for you must start afresh. Good Luck.
Hi All,
Since I have updated to JB I am having strange problems with my phone( Xperia P ).
I turn off the Wifi and the Data for the nights, but still getting email, ebuy notifications in the middle of the night.
I do not use any 3rd party software only the sony STAMINA mode.
Has anybody experienced the same problem ??
Thanks

Maybe stamina mode does this for you? As far as i know, stamina mode connects automatically (i think you have to choose this option) when you are near to a trusted wifi network. Disable stamina mode and see if this problems persists.
Hope this helps you sleep tonight
Nah, there is a separate option that enables wifi once you are near a "saved" wifi network! But this is not in stamina mode...
However, check if this setting is enabled. It is under Settings - power management - location based wifi..

Thanks for the replies.
I have checked everything is turned off, wifi off, data off, location based wifi off, I have turned even the stamina off for last night. Still I have got an ebay, gmail notification around 6am.
Maybe there is a automated sync option, which I have not found yet. The thing is I do not remember having these issues with the ICS version.
Can you not put the phone into airplane mode instead?
Sent from my Nexus 7 using xda premium
I'm running on stock 4.1.2 and mobile data is always turned off. "Keep Wi-Fi on during sleep" is set to "Only when plugged in" so the phone should only connect to Wi-Fi when it's in use. It seems that the phone periodically connects to Wi-Fi even though it's been idle for extended periods (e.g. an hour) because it's able to deliver notifications (e.g. gmail and hangouts). Other Android devices that I have, including Nexus devices with the same settings don't deliver notifications until they are "awoken".
This might also explain where a lot of battery goes. Does anyone else experience this and does anyone know if other phones/brands/models behave like this?
I presume you got an app that keeps waking the phone up every so often. Which then enables Wi-Fi to activate. Or an app stopping your device from sleeping properly. If phone is on charge then Wi-Fi on all time.
Wrong forum by the way Q&A forum.

Thanks for the reply and sorry for posting in the wrong place.
I installed Wakelock Detector and I can seen numerous "CPU wakelocks" and "wakeup triggers" but no "screen wakelocks", so I didn't expect a Wi-Fi connection to be made unless I turned the screen on and started using the phone? Perhaps I misunderstand the meaning of "Keep Wi-Fi on during sleep", especially the meaning of "sleep"? And, it still doesn't explain why other devices with the same apps installed don't behave this way. That's why I wondered if it was something to do with mods that Samsung have made to the software?

The meaning of "Sleep" in Android is when the CPU is in a mode called deep sleep, the device is set to a really low power setting so it will just run, apps can wake the device up ie take it out of deep sleep if they need to sync with a server, etc and this is what a wake lock up, an app waking the device up, and as the device is out of deep sleep for those few seconds it can switch wifi on, I personally keep wifi and mobile data on all the time so I don't know much about it.
Thanks, it looks like I have misunderstood the meaning of "sleep". I do have apps that would run periodically.
For example I use SugarSync, which I have set to only backup while on Wi-Fi and when the device is plugged in. I assume that it will have a timer set (or cron job in the old speak) so that the app can run and check for the required conditions before attempting to backup? I guess when this happens, Wi-Fi might connect and any other app that wants Wi-Fi (like Gmail or Hangouts) would take advantage of the connection? I suppose that my older devices (that run Android 2.3) might not have time to connect and so don't get the notifications that the Galaxy S3 does?
Hello experts,
I've been using my trusted S II for several years, when only half a year ago I rooted it and installed NeatROM on it (jellybean). Even before the rooting, probably after upgrading to the official jellybean, I was experiencing the following scenario:
I put the phone on airplane mode when I fly, or simply turn off both Wifi and Data (over 3g cellular network), so to reduce the battery consumption when I go to bed and don't want to be woken up by texts at 3am. I also turn off Sync option so that different apps (like gmail or calendar) won't wake up the device and try to connect to the internet every minute (and fail).
Then after a long period I turn on Data or wifi, and then - BOOM - a massive drain of the battery, which is accompanied by sluggishness in responses to me pressing the screen or even pulling down the status bar. It is as if all the apps that need an internet uplink - Facebook, Messenger, Whatsapp - wake up at once and try to get online together.
Does anyone else experiences this kind of effect? Is there a way to fix that?
Thanks in advance.
my GS9+ is on the verizon network if that matters.
In the last 4-5 weeks my notifications, especially those with sound have become severely delayed. It is especially noticeable with apps such as:
SmartThings (when doors open and close at)
Nine (Exchange email)
HikVision Connect (Doorbell camera motion notifications)
It seems to happen more often when on wifi, but i can't confirm that.
When I get up at work from my desk it is like the phone wakes up and all of the sudden I get 5-10 notifications all at once. This also happens at home. It is like the phone wakes up and catches up with a bunch of notifications that it forgot to report.
SMS notifications don't seem to ever be delayed.
Was there a software update or app update that someone knows that might be causing this problem?
Granted I don't have Verizon at all, but my s9+ isn't having any notification issues.
Did you try disabling battery optimization? I turned mine off so that the phone wouldn't put apps to sleep and etc. Power savings for wifi turned on? If so try making sure that's turned off so your phone stays connected to wifi when the screen is off.
Any of the power savings mode enabled or other power savings apps you may have installed?
Mobile data plan permitting try running the phone on mobile data only (no wifi) to see if the issue happens as well.
Are there other apps effected by the issue your having? If a select number of apps are effected (and others are not) try getting in touch with the app developers and let them know what is going on.

I'm on Verizon. Similar deal. I let a system update get applied "Just security patches, no big deal", and it broke some of my notifications. Not all of them. Just some of them. I thought this was early Sept, but might have been in late Aug.
It's "doze". It used to only happen if your phone sat still for 20 min, but it was supposed to wake up with movement. Now mine kicks on after 3 min and movement doesn't impact it at all. You are supposed to be able to whitelist apps you don't want put to sleep, but it seems to be ignoring that setting for some of my apps. After three min I can send my phone a message, and it won't alert me at all. It's not until I turned on the screen, that they all come rolling through.
