10581 Battery Improvement - It's True!

a hard reset will fix everything

2 full days now on the build 10581 and with average to high usage, the battery is approximately 50% at midnight!
At this point, I really don't think it could get any better..
Props to the Windows team!

Can you define "high usage"

I use my 920 _alot_ so I don't get many hours... But I still see a huge improvement in battery still. If I'm off work I'm getting almost 6 hours of batterlife compared to 1,5 hour with the previous build.

My battery would last alot longer if I hadn't abused it for 2,5 years though. I'm surprised it still works. I had a Samsung Galaxy S2 which gave up after 11 months.

Battery life doubled from build 36. Lumia 930.

Me too... big improvement with this build (in many ways!)

Massively improved battery life here on HTC One M8.

Another One M8 here with same experience.

Can you define "high usage"

Average to high usage, in my perspective, means pretty heavy screen on time, with task such as browsing, phone calls, emails, gaming and youtube videos.
If I can recall correctly I did the below things:

The usual browsing of all the Windows blogs (~20 minutes)
Research the lenovo yoga 2 8 (~30 minutes) (awesome little device!)
15 minutes phone calls,
Sent emails
Jet car stunts gaming for 30 minutes (I love this game, reminds me of trackmania!)
One 1+ hour long documentary on Perfect Tube and a couple of 10 minutes videos from the subscription feed,
Set appointments and reminders / note taking with onenote / saved map locations
Updates / downloaded 2 new apps, tried out, deleted..
In the night browsing news, about the asteroid flyby, sports and those Windows blogs again (!)
20 minutes music playback with groove
Searched and downloaded photos with Perfect Wallpaper / Edited a bunch of photos with autodesk pixlr
Spent 20 minutes on Readit
Many calculations with the calculator in order to build the space station in kerbal (I'm a noob)

This is pretty much what I remember I did with the phone.
Of course they where short screen on sessions for minor stuff as usual

The fact is that the usage scenarios are defined exclusively by the user and everyone has different perspective on those 3 values (light,average and heavy)
I wrote average to high usage because after all the work and media consumption I've done, I wasn't expecting the battery to last that long and frankly, it is on par with WP8.1!

I feel 10581 use the more battery than 10572

No scientific measurements here but it seems about the same (as 8.1) or slightly better on my 640 XL and 735. Standby is excellent.

Unfortunately I can't say the same for my experience with 925. Battery used to give me a full day, now my mobile phone seems to not be mobile anymore, constantly plugged in. I don't get any more than 4 hours!!

My 920's battery would last a day (or two with light usage) on 8.1. Right now on 10581, it was at 57% after three hours. Yes I did a hard reset after upgrading, so no, that doesn't automatically fix everything. And it's not like I can really turn the offensive processes off either....it seems like the worst offenders are Messaging + Skype and Cortana.

10581 battery as good as 8.1 on my 640,I charge it every day by habit and its never below 50%.The longest run is 1 day 11 hours on my battery stat.Could easily go 2 days or more and I use the phone a lot for web browsing

I wonder if MS is not giving a crap about the old S4 chipset? Maybe I need to grab a 640...
