14342 Battery usage

[xzb6np]

The biggest battery drain I have seen is having outlook set to sync by usage. Switch it to 15 minutes for all your email accounts.

640XL LTE barely lasts a day with 14342!!

The last couple of builds have progressively gotten worse - I thought. But with 14342... there is absolutely no doubt - the battery performance is very bad. Don't know what has been changed but I have woken up to a completely DEAD PHONE on 2 days since I installed this revision.

Yes, much better on 950XL.

Seems there is a rouge process or something happening that is causing a process to just hammer the CPU at 30-35% constantly. Draining the battery and heating up the phone.

svchost.exe is the process running under user: <devicename>\WPNONETWORK

Can't upload the ETL log since its like 250MB, but haven't been able to pin point why.

Happens on both my 735 and ICON. Only way I get to silence the process is to turn on airplane mode, which usually will stop it from churning.

But that is not practical, also turning on WiFi/BT/Location/NFC in airplane mode doesn't seem to kick the process up, might be related to cellular data/SIM maybe? if I remove the SIM card no heating or CPU usage, put SIM card back in and toaster mode activates....

My 1520.3 on .318 has terribly fast discharge rate, which usually results in a crash. I basically keep it plugged in all the time. Since it's getting old, I wonder if it's a hardware problem. Anyone else?

Looks like I'm not the only one - this thing (Lumia 640) is hot and eating up battery faster than my old Blackberry Z10 on 10.1.1... (EEK!)

Looks like I need to back it up a step and sit tight until they get it cured.

Someone try to switch temporary Ring to Production and reboot, and check if something change. It should stop telemetry and testing code (I guess)

I cannot test on my 650, I haven't any iussue till now

I tried Production on 950XL, stopping telemetry,NFC etc. Battery life still miserable 5 hours at best. MS doesn't care about us the now .7% of smartphone customers.

Sincerely, after decades of working on huge variety of desktops, I cannot explain such differences btwn same identical devices, despite apps ecc.
A lot of 950 users are satisfied, there's another two with light sensor malfunction, someone with battery drain. BOH!

PS: yesterday I tried the new Microsoft Healt without Band. It killed 50% battery in 2 hours!!!!

I had some serious drain happen over the weekend. Sometimes it was "lockscreen" or "Start" or "MSHealth" reporting the most usage.

I had turned off Cortana access from the lock screen and suddenly I still had over 50% after 18hrs of off charge time. The next day it went back to weird spikes. However, everytime I noticed the battery draining/heat build up, I just did a soft reset. This often resolved the issue but it doesn't mean that it resolved it permanmently as I did have to do that at least 3 times one day.

When those rogue processes are not going off and eating the battery, I get phenominal life (1-2% p/hr). Like right now: almost 8hrs off charge and I'm still at 87%.

I still have some minor issues with tiles not updating (MS Health) or store notifications (2 updates today with no notification) Skype stopped notifiying me until I did a soft reset at one point.

Edit: 950XL Build 14342

Out the 0004 minor build update, seems fixes the draining. Check it out!

Have the same issue. While reinstalling all apps, using the screen, have the ms band connected and in addition just having connectivity with about bar (for both cellular and wifi), I had draining batteries, even I was attached the power. When I stopped using it and just let it install all things, battery took 2,5 hours to load 20% :-(
It is most likely related to the cellular connection. Because during the last days i didn't enter the SIM Pin and at least it feels like the battery drains slower..
just having a look if i already got the new patch to fix it.

And I was so Happy the first 30 Minutes after the Update, as Cortana has it finally arrived to Switzerland, regardless that it uses the the Germany German and not ooffer content for my country...

by the way, the screenshot of an earlier post, where infos about the phone are shown within the browser - how can i get this? or how is this "tool" called, so I can find it out by myself? thx.
