Denim update should significantly boost battery life as, I have mentioned in this thread. Lumia 830 which has a small battery and an old processor, has 68 hour battery life compared to 46 hour of 930.
I really hope that Denim will increase duration of the battery. I bought the phone month ago and I am really disappointed with the battery, rest is ok. I just dont get how it gets drained so fast even though I'm using Battery Saver, looks like IE was badly coded, because it shows me that it used 50% of my battery in last 24h.
Say as you wish, however, as mentioned, we specialize in producing all types (SLA, NiCad and Lithium) mainship and e-batt batteries for aircraft, commercial and military and I can assure you that lithium's will loose capacity faster if discharged "deeply" than if they are kept topped.
How much "faster" is hard to say. They have a certain number of discharge/charge cycles during their life time. Deeply discharging and then charging counts as a charge cycle. "Deeply" depends a little on the particular lithium chemistry as there are several in use now.
I never said that they can be discharged "too much", I said that deep discharging and then charging will shorten their capacity faster than keeping them topped. As an aside, for "long term" storage they should only have about a 50% charge. This is why the cellphones (when new) have their battery only charged about 1/2 way, if anyone has noticed.
And this is not something I "heard" on the internet. This is from a engineer with over 40 years experience in the field (me).

I have a great tip btw: Wifi consumes a load of energy. Normally I'd let wifi stay on all day because I have wifi everywhere and a limited data plan, but it discharges more than 3% /hour only in standby already. Leaving wifi off for the whole day and only use 4G/LTE and my battery drained les than 2% /hour which is a pretty big difference. 20% discharge in 10 hours vs 10% discharge in only 2 hours...
I experience the same battery drain on my 925
I got my 930 few weeks ago and I'm not happy with my battery life at all. After I remove it from the charger, I lose like 10% in first 20-25 minutes without touching it and than it slows down. I did both hard and soft reset without any sucess of incresing battery life and there are no tasks running in background acording to battery saver. I even tried installing update for developers last week and I only got a little better stand by time as it loses 4-5% over night (about 8 hours) with wifi and mobile data on. As soon as I start using it, percentage drops like crazy. Yesterday I played angry birds for less than 2 hours and it dropped to 40% from a full charge...that not even a graphic intense game. Not to mention camera app, it just eats battery as I'm taking pictures around.
Now I'm reading here that some people gets 2 days on a moderate usage...do you guys even use your phone or it sits on a desk for 2 days? That just doesn't seem possible as in my case 20-22 hours is about all I get (including 8 hours over night) and I'm barely using it. Reading few e-mails, a little bit of messenger, few minutes of internet explorer, maybe a song or two on a youtube and taking some pictures as it never gets boring to see how good this camers is. That's frustrating, I wanna use my phone without worrying if it's gonna make it throo the day.
