I upgraded to Official windows 10 mobile using Upgrade advisor. Was smooth installation and worked fine. Then i got it to full charge and battery usage was mild. After 24hrs it was about 35% charge. I took it outside for a small time and within 30 minutes it died.

Anyone know anything? I had turned off WiFi, Bluetooth, location, sync setting...

battery drain is an ongoing issue with the windows 10 mobile. have patience and wait for future builds. :) . perform a hard reset and see if that helps out.

One of the biggest culprits in the battery drain has been Messaging+Skype. If you aren't actively using Skype for video chats, be sure to log out from the Skype service and then you will only be using the SMS messaging portion of the app. If you get prompted when sending text messages as to which service to use (SMS / Skype) then you are logged in to Skype still, and it's going to drain your battery pretty quickly.

Second thing you can do is check the list of apps allowed to run in the background and disable any that really don't need it. Some like Messaging will need permission, but others like MS Office apps don't. This should help out a bit more on the battery life. If you are still experiencing a high rate of drain after doing these steps, then you may have to perform a hard reset and start fresh again. It's always better when upgrading from W8.1 to W10 to do the reset and build a fresh system rather than restoring from the W8.1 saved profile. This eliminates any mixing of the older W8.1 apps and data with the newer W10 system.

My L640 can usually get 2 full days on a charge with moderate use, and about 3 days over the weekend when I'm not really using it. So I know it's possible for you to get similar results.

How did you upgrade on lumia 640? It is still not available

[awidy seiza]

You should hard reset and fresh install (don't restore backup)
Mine was upgraded and done hard reset,everything works well and battery goes for up 8 hours with normal use (social,browsing,take photos,music)

[weaksauce27]

Was your L640 the at&t version?

If you are using glance, set to turn off in 15 minutes. Also, change your email setting to check your inbox less frequently.

I just installed and will reset it soon. Hope it will be fine now. I was getting around 24hrs with normal use. Had a hard reset before upgrade and started fresh. Does that count to smoothness or I have to reset again with windows 10?

Yes, I signed out from skype the first hour itself. I want my messaging to be clean from online activity. Had turned off different apps from background, but i feel confused with multiple places to control background running.

You have to install UpgradeAdvisor to get update

Let me check with hard reset :)

I am running a version without Carrier Lock (In India)

Glance is turned off.


I feel the gallery was refreshing when i closed and the Onedrive must have did something even though i am not logged into onedrive from photos app. Anyone experienced that?

[abhishek singh21]

resetting after upgrade is preferred. don't restore the data but start afresh. good luck. :)

[Maurizio Troso]

And don't forget looging out Skype

[awidy seiza]

Mine have been quietly good performance battery,all app was allowed to running background,including messaging and skype, but battery can used for all day

This is the best experience of w10m compared with insider realese before

[Sedp23]

I only get about 7 hours battery life on mines if that

Hi everyone, I'm new to this forum and I hope someone might be able to answer my questions.

I'm not on Windows 10 (on Denim, still, and am on Insider but haven't upgraded), BUT I have a Lumia 640 LTE (yes, on AT&T, but successfully running T-Mobile ROM with correct bands, etc, and everything works fine) and I've been having a seemingly specific battery drain issue on the Denim firmware.

The reason I am posting in this thread in particular is because of @Rugish Dapeca 's comment regarding the battery drain issue re: Skype and I was wondering if Skype (and Internet Explorer) is a battery drain on all Lumias and on all versions of Windows for Windows Phones... or if it's only an issue on Windows 10.

(If this post ought to be moved to its own thread or forum, please do so and excuse me for posting in the wrong place.)

The reason I'm asking is because I've been having a battery drain issue on my 640 and I THINK I've been able to track it down to regular Skype and Internet Explorer usage being the two biggest culprits... but I'm not positive and if I can confirm or deny with other Windows Phone users, I would really like to before I finally give in and do a hard factory reset and start all over.

I can listen to music overnight/6+ hours nonstop through headphones, watch HD video clips, music videos, and movies on my SD card, browse OneDrive, and even type up Word and One Note documents while syncing with OneDrive with minimal or 'expected' battery usage, but when I'm using Internet Explorer or Skype - especially Skype, my battery usage starts getting out of hand. Intense text messaging can be a bit bad at times, but better than Skype and phone calls are fine, too, as far as I can tell.

I used to own a Lumia 635 and where I had noticed a potentially mild issue, it wasn't even remotely this bad (I don't think)... but then again, the 635 also had a different screen type, etc.

I'm a veteran Windows Phone user and have Battery Saver always on, Bluetooth and Location and NFC (and etc) always off, etc., and if it weren't for Skype and Internet Explorer (and maybe Microsoft Health app since I have a Band 2, but I disallowed background processes and only turn on Bluetooth once a day to sync), my phone's battery life is otherwise fairly excellent.

I know that at this point, a hard reset + clean start/no restore might be my only option (or getting a new 640 if it's faulty), but do I really need to?

Is this likely a phone problem/general system problem or a Skype and Internet Explorer problem or... something else?

Thanks in advance for any insights.

Skype normally eats battery faster. Internet Explorer was just at boundaries for me with Denim. You should check whether skype and other important apps are installed on Phone or SD card. May be there is some relation with battery drain.

[Aithan]

Hi teckris!

Thanks for the reply. Skype is on the Phone and there is no option/App location for Internet Explorer. I think I tried moving Skype to SD before and it didn't work.

Does it matter where the apps are? Phone versus SD?

Internet Explorer didn't exists anymore. And you can find apps location in Settings -> System -> Storage

[Biotic Blue]

Don't know about battery drain on Windows 10 as my L640 unlocked UK (CV) is still awaiting the update, but in the past and on my Win 10 L930 the internet explorer/edge appeared to be draining battery, not sure about Skype as I didn't look in that much depth and particularly on my L640 seemed to work itself out.

[andrew bainbridge]

How did you upgrade on lumia 640? It is still not available

Windows store. Upgrade Advisor. Install. And you'll find out.

[GRAI2008]

I tried all of that but the battery is still draining on mild usage. I don't use skype or youtube

[PGrey]

Are you 110% sure your Skype Messaging being logged out and un-linked?
Several have mentioned it, and it's pretty critical, this app is really in need of some work, before prime-time, IMO.

My 950XL will do all day+, at moderate use, and have 30-50% left, but if I enable Skype Messaging (this is NOT the regular Skype app), I'm lucky if I can make it 6-8 hours, it's pretty bad.

Glance is bad too, if you have it on all the time, but these messaging apps that are half-baked (unfortunately the built-in Skype Messaging app is here too) are really, really tough on battery life, almost to the point of ridiculousness...
