Real World Battery Life

[christenmartin]

Will do!

I don't have anything to lose by doing a reset in this case. The only files I care about are on my MicroSD card and the rest is synched to SkyDrive. So what the heck, it's worth a shot and I've got nothing to lose by trying it.

I think this will work! Good luck.

If he means what I think he means, then I'd like to point out that with moderate use you'd be lucky yo make it through two days with any smartphone. Although my Lumia 920 had a weird issue where the battery would just start draining really fast for no apparent reason, so I hope that's not what's going on.

 

[christenmartin]

I had the same type of issue. I did a reset in it, been good since. If I have more than normal battery drain or flickering, I will go through the normal making sure nothing is running in the back ground , ie is shut down, if all is well it has always been an app that did not load right. Uninstall and reload. Move on.

I think I'm going to have to agree with the consensus that you might have a defective unit, because even my Surface Pro 2 (which should, obviously, be sucking juice at a much faster rate) is getting better battery life.

Same here. When I had the RT I was getting more as well.

Just did a rundown for 90 mins. Only surfing, 10 mins video in IE, battery dropped 22%. This would be less than 7 hours. Screen brightness was 50%, 5 bars WiFi.

Would you think that something is wrong with my surface 2?

That's drain more than I'm getting. I seem to be getting 5 to 10 % an hour. I'm not sure how much the battery will "settle" with time.

how poor? Less than 12 hrs heavy use?

Mine drains really fast in the beginning, but slower from 50 percent downwards.

I have a new l920 and my battery is poor I just have 3 days with the phone what should I do ?

Check what's running in the background, shut off things you don't use, and give it some time.
My Lumia's battery life improved with every day usage.
Now i tend to have 1.5 / 2 days before i have to charge it again. At this moment i have 69% and still 21 hours and 13 minutes to go untill i have to charge it again

So, after my reinstall I am two hours in (I mostly watched stuff on Netflix) and have burned 28%. Better than yesterday, but still not good enough to get me near to the ten hour mark. I suppose there are things I could try to increase my battery life, but I really shouldn't need to go get close to what is promised by Microsoft. It's not quite a deal-breaker for me, but it's very disappointing.

Also I'm having a weird problem now: every now and then a bar of what appears to be nothing but a mess of pixels flickers on my screen for a single frame. It doesn't appear to be tied to any particular application either. Very puzzling.

 

[christenmartin]

Maybe better battery with use. That's how my phone was. I took mine off the charges yesterday morning and haven't charged it yet. Its been used quite a bit. more than 7 hours.

 

[mcheiron]

I chatted with MS support and they recommended an exchange. So that's what I will do. I will see how the next one is doing.

I'm curious: People who are getting 10+ hours of battery life, do you have Bluetooth turned off?

Mine was on. I turned it off to see if there is any change.

Definitely starting to sound like you picked up an effective unit, that's worse battery life even than my Surface Pro 2, and the odd pixel thing only seems to support that theory.

My battery life also seems not to be like intended.
I get 6-7 hours of expected battery life from powercfg /batteryreport.

When playing games (MS Solitair mostly) it leaches like 20-25% per hour.
When only surfing and youtube it takes about 15-20% per hour.

Don't know what to think about those stats, seems like defective battery or something strange with software or apps.

So for me it appeared that my surface 2 was suffering from battery issues but I am much more hesitant to claim that now that I have turned brightness down to 50%. With max brightness before I was only getting 7hrs of active usage consistently. Now I am on pace for 10hrs.

 

[hcrick]

That sounds much more in line with what you should be getting.

 

[HeyCori]

Noticed that my battery drains pretty fast too. I was dropping around 12-13% an hour. That's mostly from web browsing and Office. Also had a few games suspended in the background. With drainage like that I couldn't imagine getting anything more than 7-10 hours out of mines. I also don't employ any battery saving techniques either. WiFi and Bluetooth stays on. I also heavily use my Bluetooth keyboard as well. Screen brightness never dips below 100% either. I can't tell if that's common or if something's wrong.
