Battery drain with 1520 on latest build?

[Skulls138]

Since last night, I have been experiencing a bad battery drain. It seems my two highest usages are Skype and messaging, and the lock screen. I always have battery saver on. I keep all the extra stuff off (Double tap, glance, location, etc) Six hours of no usage brought down my battery by over 20%. I did a soft reset, and nothing. Any advice? Thanks!

It seems my phone is also sending stuff over wifi/data when idle, or being used. And they the culprit is my default lock screen....80% used in back ground.

Hmm. I left my phone kind of generic. Great battery life. I do mean great. I did change lock screen and start screen, but what are you doing differently?

Nothing out of the normal. I do everything the same as in WP8.1, I have no clue how my lock screen could be using 80% of battery in the background.

For me battery is just like wp 8.1 so far. 3rd day n i have no serious issues.

My 1520 was nearly dead by the end of the day yesterday, which hasn't happened in a while, so I'm going with "yes, battery drain".

I have a battery issue on 1520 as well. Turned off location, battery saver mode, wifi off but nothing helps. I have noticed that the upper part of the phone remains warm both from front and back. Anyone any ideas?

Any recent apps downloaded? Had a issue with latest FB app causing phone to get warm and battery drain. Took it off and solved issue. This was on the Icon.

No app changes. Just upgraded to latest build from 8.1.

I haven't downloaded any new apps. For everyone else having a drain issue...What does it say under battery use? Like I said, mine is display/lock screen with almost 90% in background.

 

[dajma00]

Mine says display 79%. If I go and look at edge performance it also has display as 95%. So looks like some kind of display issue? But then the drain continues even if the phone is not in use and display is off.

 

[Skulls138]

Edge is normal for me, I hardly ever use it. Now that I checked however, my messaging app is a pretty high usage, as well. Not nearly as bad as my lock screen though. I did a hard reset after upgrading, I'd hate to have to do another one so soon.

 

[dajma00]

Have you updated all apps? I went to store and saw lock screen update was pending. However that update has also not helped.

Check that your email is not constantly syncing as that happened to me , I had to delete account and start again. That fixed it for me.

 

[Skulls138]

Only updates I did were last night; and one of them was a blank update with no name or anything. Odd.
How would I check if they were syncing constantly?

Last night's blank update was Cortana. It switches on the new W10M Cortana for India and Australia. Should not do anything to affect your battery life.

Email synch turned off. No respite.

Email synch turned off. No respite.

A Microsoft technician recommend I hard reset. Afterwards, seems okay. But now my Skype integration is broken. Ugh!

 

[dajma00]

Skype integration is broken anyway....

Let me try hard reset...
