Poor battery life, only 14 hours fully charged

[tranite]

I am having some problems with my battery on my Lumia 920.. I have read on this forum on everything I can find, and have asked Nokia and read on their Troubleshooting guide.

I have turned off all background tasks except myBattery, the internet sharing, Bluetooth, tap+send, location, kid's corner, and all of that is set to off. I have the display+touch sensitivity set to normal (but I can use gloves and keys with both Normal and High sensitivity...). I have completely removed the Google account from the phone, as I have read in this forum could use a lot of battery, so I'm only using the Microsoft account, Twitter, Facebook, Nokia account and I have also added Outlook.com separate from the Microsoft account (just because of the icon on the live tile).

The screen is always off, and I don't use any lock screen apps, I only have a single photo on my lock screen.

I have also turned Connect with Xbox off in the Xbox Live.

My phone always charges over night, and it's now fully charged with 100%, and estimated time remaining says 13 hours, and time since last charge is less than 1 hour. I think this is very very low! What is wrong, I have done everything possible for getting the battery increased. Some solutions for me?

I'm not sure if you're actually experiencing a problem, or if you're basing this post on your "time remaining" reading after a charge.

If you're really only getting 14 hours on standby, you have a problem. If the "time remaining" thing says you have 14 hours left, that's not something to be concerned about. It's meaningless.

I get 7 to 8 hours, think that's bad? I'm furious, don't know if its the new update or the phone since I installed it right when I bought ot

No, the time remaining is correct, the myBattery app show it as well, and on the graph the battery level is sinking drastically. It's totally OK when I actually uses it, I use it a lot to surf on the web, play games, watch videos and so, and then I'm satisfied with the battery. But now in the holidays, I have not used it for anything, it's just been there on the table or in my pocked, and I still have to charge it in the evening because the battery only lasts a little over 12 hours.

Also, I do NOT have the Portico update installed, not available in Norway..

So yes, I'm only getting about 14 hours on standby. That's the frustrating part! Would it help by doing a hard reset or?

I'd be happy to offer some suggestions, but I'd ask you to do this first: before bed, FULLY (100% + a half hour) charge your phone. Remove it from the charger, and let the phone sit there untouched for 8 hours. Report back on what % of charge you have left after 8 hours.

Confused. Is the 14 hours based on time remaining you see or actual performance??

Of course the battery shows the same as when u go to setting. It pulls the data from there.

I was similarly confused. OP says that s/he is only getting 12-14 hours on standby in actual use.

Thanks Kooosh, I will try this tonight.

The actual performance of the battery is pretty equal to what the phone says is estimated time remaining.. But the performance have improved some more over the night, I did a soft reset and have slightly used it today, battery is 80% now, after 8 hours usage.

I am satisfied for now with this battery performance. I also turned of data usage and WiFi for standby, and that was some of the improvements I think. Thanks!

Just for you reference, went a day trip with my sexy green N8, my ATT cyan 920 stay home and got around two days on standby.

Ok, so I installed portico a week ago or so just when I got the 920 replacement, and battery went from 100 to 72 in 9 hrs overnight in standby with weather channel and a battery app I forgot what its called. That's terrible. So last night I flashed to old software and left it overnight again with same apps in background. in almost 9 hours battery was at 90. Is that good for it to go down 10-11 percent in 9 hrs? Just wanna make sure I don't have to send this back, and also really confused why some ppl have great battery life with the new update and some have terrible,my last phone had great life with portico.

I generally lose a % per hour while the phone is completely idle overnight. I don't think that's unusual. If you restart your phone in the morn, you might find that it's misreporting. I can gain up to 10% of reported charge just by restarting the phone. I'm convinced there is some battery reporting bug in the OS.

I tested tonight without charging to 100% battery, but yesterday I had 45% battery left, tomorrow 8-9 hours later it was 43%, 2% loss in all those hours! I think that is great. But I don't have the Portico update installed then.

I am now satisfied with the battery. Is it good for the phone to be turned off/on regularely, or is it not necessary? I believe the battery did increase a little after I turned my phone off and back on again, don't ask me why..

If rebooting fixed the issue, then I'd wager that it was some rogue app that didn't close in the background and kept eating at your CPU and, subsequently, your battery.

You have NFC, bluetooth, and location on, and you're complaining? I know the whole "I wanna actually use the phone and get good battery life" argument, but I doubt you use NFC and bluetooth all the time. Turn it off if you don't use it. I had the same experience with battery life, until turned those off and performed a hard reset. Battery lasted 21 hours yesterday.

Question, I installed portico and then I flashed back due to battery issues. So now I go back to settings and search for software updates and portico doesn't appear, it says its up to date, I reinstalled portico basically then? Or will it not search? What's the firmware number for portico att?

 

[Kooosh]

What's the firmware number for portico att?

1232.5951.1249.0001

haha what a fail, I reinstalled portico basically then. Wow I feel like an idiot, even tho I did drain the battery until it wouldn't turn on like someone suggested and its at 83% after 5 hours, I think that's pretty good. I'll keep monitoring

 

[Kooosh]

Yeah, I don't think there's a way to do a reset with AT&T and not get the Portico update. You can also look forward to a bunch of Nokia's settings updates to be pushed to you shortly.

Don't go by what Battery thing says... I had something like 83% battery and 2 hours battery life remaining according to that (I have screenshots from my WP7 if you want proof). That was with 1 background task, no location, no wifi, no Bluetooth, nada. Brightness set to automatic (but was setting to the medium level setting). If I only got 6 hours out of both batteries I would have hit the roof... would happen on the day I forgot my spare battery too... >_<

 

[anon(5503495)]

Ooh ever since I completely drained it till it wouldn't turn on, its at 14 hours since charge and 21% left, not bad
