I came from a lumia 640 and so far the battery life on the 950 xl is terrible. Im using the single sim build .29. Idle time is great, about 1% an hour but usage is terrible, in edge my phone uses about 1% every 2-3 minutes. Also I've been having some weird things going on with battery icon %, sometimes it will say 60% and when I come back after not using my phone for an hour or so it might say 63%. Its done that a few time, other times it will stay on a % for a while then drain a few really fast. Is this a faulty phone or just new phone os issues? Also I have drained and charged a few times to calibrate it as some have recommended.

Any new phone takes few battery cycles to settle down...and the new build improves almost everything...update to latest build 36...iam happy with my 950 battery life and don't restore old data from old phone

[bijak_riyandi]

Let it be. After a few weeks it should get better. Also, try reducing the email sync time and turning off the features you don't need.

[garyhartaz]

My two cents.......HARD RESET your phone. I too waited a week for my battery to magically get better and it didn't. A hard reset fixed everything. IMHO, when I immediately went from .0 to .29, something requires a hard reset for battery life to be better.

- 8 cores
- Iris scanner on
- 2K screen

and you want the same battery life than your 640?

[Wookieekiller]

I've already hard reset a few times, had it since last Monday and I don't have my email app even setup yet.

EDIT lost 3% just typing out this response and editing it.

check and close background tabs in Edge. Edge doesn't close other tabs, so you have to be diligent about closing old tabs (esp. ad-serving pages, which keep trying to draw ads in the background) .

[Wookieekiller]

Yep, I've been keeping my tabs closed. Only ever really have a max of 2-3 open. Usually this site and facebook site is all I do in edge most of the time.

all 8 cores aren't active at the same time. its 4 cores at once. which 4 depends on how heavy your using the phone.

The 2k screen is a super hog. My battery has settled down and that's the biggest culprit. I get 2-3% standby drain in an hour with iris, location and Bluetooth on in standby. I lost 5% after 25mins just having the screen on and on the start screen.

I'm hoping for some firmware optimizations here but I've come to accept it's a daily charge for this phone.

I have come to accept whenever not doing anything charge the phone! Battery Sucks!

Yes, I know it, but the 4+4 on 950 > only 4 cores on 640, if you are taking pictures or gaming, the 4+4 will be active.

The battery is ok, just need more optimizations with future updates. Also, we tend to use more a new phone, using more the screen.

My battery is slightly better than my LG G4, however it wasn't too cracking initially.

[jazzedmurf]

Probably mirroring what others have said, but my battery life got WAY better once I let the battery cycle a couple times AND (and this is the important one, imho) edited which apps were allowed to run in the background. After that, battery life was on par with other users using iPhones with similar usage patterns as me at a conference we all attended.

[jeetu4444]

Iam getting good battery like with 17 to 18 hrs with medium use have activated windows hello...and like 10 apps on the background...i also have lg g4 which last about 12 hrs with medium use

All the above don't have to do with the device itself.
They are Windows 10 mobile bugs. I have exactly the same problems on a 730.
Give the OS some time if you have the strength to do so. They will fix them! (sometime)

And no, your device is not faulty, the OS is faulty :P

I suggest updating to the latest build and doing a hard reset.

[jagger9270]

As phones are designed with slim body, the battery should be slim too,Which means less power capacity

[ronaldme]

I suggest updating to the latest build and doing a hard reset.

And remember, it is not the same a hard reset using the option on settings than the hard reset using hardware buttons.

Hey guys, are you using the integrated skype features with the messaging + skype app? A lot of people have reported that it's background task has been sucking the life out of their phones.

If you don't rely skype that much, try logging out of the skype video app (which stops the integration) and see how battery life is after.

It might not help everyone but you could at least try.

Please clarify which method and how to do this "hard reset".

[jlangner]

Please clarify which method and how to do this "hard reset".

Hard reset resets back to like when you bought. You run setup again, download all apps, restore from backup,etc. - Go to Settings, System, About, scroll to bottom and select "Reset your phone"

[Wookieekiller]

Ok so I've tried what everybody has recommended, did a hard reset from .29 with the new firmware (since I can't get .36 since i'm a single sim XL) installed all my apps, did a soft reset when my phone was 100% charged. After a 9 hours of what I would consider very\light use (mostly some reddit, a decent amount of edge, some texting and messing around with phone settings, downloaded a 7MB app and browsed the store) I had 48% battery left and I just took this pic a while ago of my battery (it's been 21 hours now and I've been charging it up) Seems like my screen is taking almost 61%?? I don't think my apps are really using any battery since system is only using less then 20%. So it seems my usage really isn't affecting my battery but my screen. I had my screen on auto btw which I think would have it at 50% since I was in a fairly bright room.

Hard reset using the about method only reinstall the OS on the OS partition, the buttons method delete all the internal storage, not only the OS partition.
