I just received my Rezound new yesterday, downloaded some apps from the market, and set everything up for normal use today. I got it off the charger this morning around 7:30am at 100% and its dead at 4:30pm. I would consider my use light today as I only used the web for maybe 10 minutes. I mostly did things like add contact shortcuts to my home screens and move icons around, and download maybe 2 new apps.
I came from a Droid 2 which got pretty awesome battery life running Liberty 3 and I'm wondering if my usage time is normal.
Total Time 8h 22m 33s
Display 80% (Time on 2h 45m)
Call Stand 5%
Phone Idle (Time on 5h 37m)
Android System 3%
Dolphin Browser 2%
Android OS 2%
Wi-Fi 2% (Time on 1h 38m)(I don't believe I was connected to any networks though)
Drop box 2%
The screen is what kills it along with LTE. If your screen was on for 2:45 that is why. The display sucks battery on this phone.
Thanks for the reply, I figured that was the case, but I still thought I would have gotten a little longer. I hope a custom ROM will help some with the battery life.
I am on stock rooted and don't really have battery issues. Typically I get 12-14 hours which by then I have easy access to power. If it is going to be a long day, I use the extended battery. It is not uncommon to still have charge left going into late at night.
I have the screen less than a third of the way on the selector and have Auto brightness turned off. Screen timeout is set to 1m but when I set the phone down, I have a widget called ScreenOff that I click to blank the screen. Primary reason for doing that is so I don't accidentally enter some app, but a secondary is that it turns off the screen before it would normally timeout.
When I am at home or at work, I use WiFi almost 100% of the time which due to strong WiFi signals there, (for me) uses less battery power than LTE.
Otherwise, I have LTE on.
Right now today, I am about 50% with 9h 12m of use. I fully charge nightly with the AC charger on my night stand so when I get up it is 100%.
I have an extended battery, but normally use the stock battery unless I know I am going to be away from the office for long periods of time.
I am not much of a game player, but I do watch short videos from time to time. I have streamed music, but don't normally. I get 10-20 calls a day typically and use my browser on a regular basis (reddit as well).
The camera is Awesome!
Unless your display was on max brightness and you were streaming HD movies. That's bad battery life. I get 2 times that even with autobrightness, maybe your battery isn't broken in yet
A good measure is 30minutes display time per 10%, and 1% per hour with 3G and normal sync scheduling... If your apps sync ever 15 minutes that will kill it, and 4G should kill it a little more than just 3G... Minor fluctuations are still OK, but you shouldn't have 15 minutes per 10% unless everything is basically on full blast
My battery life using the setup in my sig is usually very good.
I can easily make it through a normal workday listening to mp3s from my card/texting etc using the standard battery. My screen is set to 30%, screen timeout to 30 seconds.
I do like to stream audio however using iheart radio or Sirius radio online. If I do that, I'm lucky if I make it 4 hours on the standard battery (without ever turning the screen on) When I am going to do that, I use the extended battery and keep a 2nd one in my pocket. I have two external chargers I use so I always have spare fully charged batts.
I actually prefer the feel/weight of the phone with the extended battery and the HTCPedia cutout hard rubber case.. That gives me a better grip on the phone and I barely notice the weight difference when it is in a Jean pocket.
I guess it just depends on the actual phone itself. My phone charges everynight. I pull it off the charger at 6 am and by 10am the battery is dead. I have 3 batterys, and a wall charger that I carry around. I don't consider myself a heavy user either. No music or videos. Only text, gtalk, gmail and a phone phone calls that last a few min each. I only have google and exchage set to push. My 2 yahoo accts sync every 4 hours. I do have fecebook as well. Screen is very dim. This was all using rooted cleanrom.
I am now back to bone stock, with a CLNR phone that just arrived yesterday (due to connection problems with my computer) So maybe a stock rom unrooted will make a difference. Heres hoping!
Sad.....great phone, I love it!

This. I was playing "draw something " with friends today at work and even with a fully charged extended battery it only lasted about 3.5 hours with the backlight at 100% and oc'd to 1.7 GHz. But that was constant usage for those three hours.

That game literally jumps out of your phone, and rips your battery in half. But its way too fun.

Diff. Roms equal diff results for me. All of the ICS roms I've tried all keep my phone up time and awake time the same. Is anyone else having this issue? Due to this, I typically end up getting around 5 hours of life even if I leave my phone off for the duration of that time. It's annoying because I really want to stay on ICS but get double the battery life out of the GB Roms.

On Scotts CleanRom 3.6, with fairly heavy usage (hour of solitaire, hour of browsing xda, texting, 30 minutes of phone calls) I can get about 10 hours before needing a charge again. Before I updated to 3.6, which has the 3.8v battery fix, I could only get about 5 or 6 hours of similar usage. I don't recall if prior versions had my awake and up times the same, but I haven't noticed it recently.

I take it you don't stream audio like I do??
I just got my Rezound yesterday, and have noticed a surprisingly poor battery life. I did all my setup yesterday, and fully charged the battery over night. After unplugging it this morning, I listened to music off the sd card for about 45 min, browsed the net for about another 45, then stopped using it for a while. I noticed the battery was about halfway through, so I plugged it in to my car charger and did some more Internet stuff. However, after checking the battery info, I realized that even plugged in to the car charger it was consuming more power than it was taking in. I finally had to turn it completely off and let it charge to get the battery from yellow back to green.
This is the same charger I used for my Droid X, so I know that it is working...

I've been running BAMF ICS v0.9 for a few days, and the other versions before that. I get 12-14 hours with 4G on, and 20-23 with 4G off....I keep the screen on 40% brightness
Watch your clock speeds if you are on ICS. They constantly Max out, both cores. That's where your battery life is going.
Sometimes data flickers for me on random days, that's the only thing that wears my battery down fast. But I can still go through the day have 40ish percent left. If it doesn't flicker I can go through through day with about 50% left. And if in on Wi-Fi most of the time I have nore than that left over. And that's with using the phone for a couple of hours with the display on.
Trying ineffabilis with DSBs 1.1.3 kernel and undervolt it some
for me, battery life killers can be streaming audio (sirius xm or espn radio) and definitely jelly wars. Phone will die on extended battery in about 4 hours of continuous play.
Otherwise, normal usage, I get 10-16 hours of use on my extended battery before swapping it out (use 2 extended batteries).
4g definitely runs the phone hotter than wifi (about 20 degrees hotter for me)
The only time my phone gets around 95 degrees is if it's on a charger and I'm watching a movie, and it takes about an hour for it to feel warm, which could even be caused from me holding it the whole time. 4G doesn't get my phone any hotter than 3G Or Wi-Fi. Guess every phone is different though. least we get signal xD

I just bought a Droid X2, but have decided to take it back for an LTE phone before the change in unlimited data.
I really don't like the way the charge looks, but it seems to be just as good as the TB. The TB has the likely potential to have a better community and better roms.
However I cannot have a phone that cant hold a charge for a whole day. And I do keep my phones for the 2 year duration of the contract, so whatever I get I need to be happy with.
I get the idea that the TB lasts between 4 and 8 hours. Is this a hardware issue, or is it the ROM which would be fixed as time progresses?
It is pretty bad. If you live in a 4G area, you should get the extended battery.
There are some settings tweaks, especially in the stock ROM, that help tremendously. The notification/background data is what kills the battery.
I always get at least 8 hrs with normal to heavy use.
But if your streaming video constantly, yeah like 4 hrs.
Most I have seen is around 20 hrs.
Seems like it always dies with about 4 hours of awake time or actual usage.
In a 4G area. And I think it will get better with hopefully a new OTA.

If you are going to play with ROM's, standard battery life is real bad. I loose about 25% of the battery, 4G downloading, then flashing 1 ROM!
Add 2 hours worth of on anf off fiddling with the screens and setups takes it down to 40% remaining, then I have to turn off wifi, and 4G to get through the workday, ending <10%. If I do 2 ROM's, i'm dead before lunch. Gotta get a cable for work.
Get the extended battery. Mine lasts typically a day and a half with it, moderate usage. Awesome phone.

I can get a full day out of my phone with moderate use (texting, calls, web browsing). I have my settings tweaked and have juice defender running which really helps. I'm on stock ROM and am not rooted, there is a lot you can do to improve the battery.
Well if you use your phone as much as I do then you would be surprised how quickly the Barry drains out haha
Sent from my TB yo.
Mine is usually 60-85% display, and I have it on dead minimum brightness unless I'm outside in the sun, in which case I set it to auto for a few minutes. Mind you, that's maybe five or ten minutes max of screen on time, two or three times a week. On the other hand, a twenty or thirty minute phone call can take ten percent off; I'm one of the people who sometimes remembers that it can make calls, too, so my experience is probably a bit off. I also have most everything set to sync every 2 hours, but I have imo.im running constantly.
If I'm using it pretty heavily, it may be down to 40-60% on the standard battery by lunch, which would be about three or four hours of screen on time. I'm in a 3G area, btw. I just carry a charger; which has the advantage of making other microUSB people happy when their phones die (and we can mock the iPeople with proprietary chargers). Yes, the battery sucks, but every phone has trade-offs.
If you won't have any way to charge the phone (car, wall, etc) during the day, then I don't think you will be happy with the phone. Between my wall charger (or USB cable), car charger, and two batteries (spare is the Seidio 1600 mAh), I'm satisfied.
As for the Droid Charge, the Touchwiz UI compared to Sense is a non-starter.
Is it bad? Yeah, seems like. Is it as bad as everyone is making it out to be? I dunno. I remember a lot of people complaining about the battery when I got the Incredible. With light use (about an hour of internet and email over 3G, one or two half hour calls, and a handful of texts), I'd charge it every other night (and have 30% or so when it went on the charger).
I picked up the Thunderbolt yesterday and charged it overnight. It came off the charger at 7:30 this morning, and I'm showing 54% as I'm typing this at 8:45pm. Since it's new, I was probably fiddling with it more than usual (but not a ton more, as the differences between the Thunderbolt and the Incredible aren't huge).
So with 4G on, yeah, it runs it's battery down faster than my old Incredible. But it seems like I can make it through a day without much difficulty.
EDIT: I figure I might as well mention my settings.
I have the brightness set to about 30%. I shut off any and all vibration. Screen timeout is 1 minute, volume is maxed for everything. Bluetooth and GPS are off (unless I need them). The weather widget updates every three hours. I don't use any other widgets that use data (just a volume profile and a power control widget). The phone can do background sync for my contacts, but my gmail, other mail, and Twitter (Seesmic) are all set to update manually.
I'm getting about 8 hours of moderate usage here as well. I've come to terms with the fact that using a device that is more powerful than my netbook will come with some battery trade-offs.
hey guys,
I'm going to follow this thread for a bit. My HD2 jumped into the Harbor yesterday and will probably be switching to Verizon for my next phone. I'd really like to get the TB, but am really concerned about battery life.
It sounds like people are getting a battery life similar to what I was getting running Gingerbread off the SD card on my HD2...which didn't quite cut it for me on days I was working in the field and not able to charge. But at least with the HD2 I could run WinMo on days like that and not have worry.
Keep the info coming!
thanks

Hello, im currently running with juice defender, but i was wondering if you could help me with what all settings i should tweak to help the battery?
After applying the MR1 OTA update I still wasn't happy with my battery or GPS performance, especially compared to my past phones (Incredible, X, original droid, blackberries, etc)...
After doing a wipe and reloading the apps I use by hand, I have seen battery life match the Inc in 3g only areas, and GPS lock on my location consistently in under 7 seconds.
In mixed 3g/4g areas (where I live), similar results. Battery life and GPS lock are very much improved. And the TB now makes it through the day for me.
In solid 4g areas, well, last night I was surfing the web, reading, looking to see if the GB update for the X had hit. I went to bed around 1 am with 80% battery, didn't hook to charger. This morning at 9 when I looked it had received some emails and auto updated some apps.. battery was at 55% so that is better.
It's still not as good as my droid x, but the TB is certainly more usable than when I first got it a month and a half or two months ago.
The t-bolt is better than my inc was, with bams GB rom I got 12 hours of heavy use with stock battery....my 2 cents...
I just tested my battery life. It was about 2 hours with Carl pagan cosmos on 2g. 4g really eats the battery. After I recharge, I'm going try it over 3g and see if that makes any huge differences.

I've not been able to drain this thing since I got it a week and a half ago. I have to say that I like to charge things over night. I've not been able to get the Photon below 40% before I go to bed each night.
I hear that you need to drain it full at least once but my habit of charging things overnight is getting in the way. Should I just let it go overnight one night?
I was under the impression that completely draining Lithium Ion batteries causes more harm than good.
"The smaller the depth of discharge, the longer the battery will last. If at all possible, avoid frequent full discharges and charge more often between uses. If full discharges cannot be avoided, try utilizing a larger battery. Partial discharge on Li-ion is fine; there is no memory and the battery does not need periodic full discharge cycles other than to calibrate the fuel gauge on a smart battery."

Also, i'm sitting at 46% after 15 hours of normal (for me) use. not to shabby. I should mention i'm running Juice Defender and build 4.5.1A-1_SUN-198_5 from the dev. forums and i'm connected to WiFi 90% of the time.
going to try tomorrow without Juice Defender and see how it does. After that i'm going to disable SPB Shell and see if that makes a difference.
Thank you sir. I don't want to root my phone so don't run Juice Defender but I do use the Data Saver in stock a lot. I usually just listen to a lot of music and look for new stuff on FB, check XDA forums blah blah blah, yada yada yada...
I'll not feel paranoid about charging my phone now lol.
Now with my tablet (Acer Iconia A500) I did root and load a bunch of different stuff. This is my first cell phone though and I didn't want to mess with something that I have to pay a monthly charge for. I know I could but it's my first cell phone lol.
How much are you guys using it? For me, I use about 30min talking, 1 hr heavy wifi use, 1 hr light wifi use (reading), 30 minutes playing with settings, and the rest of the day idle...that gets me to about 30%.
I actually thought that is kind of weak. Maybe my battery isn't as healthy as yours? I've only had it for 5 days. I charge it every night.
I use it for about 7 to 8 hours of music, FB updates/posting, checking XDA, about 10 minutes of calls and so far some Netflix watching just to show off the phone to my peeps. Oh and some picture taking.
I am the same way I hate to discharge it completely and its been very hard. I've went a day and a half without charging before it went under 10%. I will say that I am on Wifi 90% of the time as I have wifi at work and at home other than that its on performance mode so no true bells and whistles. I'm thoroughly impressed coming from the Evo.

Average day for me is about 30 to 45 minutes of phone calls, 80 to 100 texts, few conversations on google talk, 30 or so emails on three accounts and i have trillian running connected to two accounts.
Connected to WiFi most of the time, bluetooth is turned on (not connected most the time) and brightness set to Auto.
I really dont see how this phone is a monster when it comes to battery life, I've actually been getting the exact opposite. I just fully charged my phone and after running for 2hrs and 7mins its down 78%.... This phone has yet to last me for the whole day. What am i doing wrong? I dont have tons of widgets and the only app that im running that might pose a problem is Go Launcher

Is that your screen on time? If that is then I would say that is impressive already. When I had the epic on stock if I use it for 2ish hours screen on time. I would need a recharge. (Got a lot better after using custom rom. Around 4 hrs screen on time before recharge)

For the past couple of weeks I've been swapping batteries with an external charger one to two times during the course of a day (plus the overnight charge)... Looks like it's time to do some housekeeping...
Edit: used to have battery life like everyone else in this thread though! While at the climbing gym last night I noticed that the thing felt like it was about to catch fire against my thigh - it had burned through about 60 percent of a freshly charged battery in about two hours. I have a nagging suspicion that I neglected to uninstall something (or a few things), and now something non-existent is constantly being polled for as a service after I launch some app for the first time...
when i got my phone it did great on a full day charge, but now with it just sitting at the office its at 70% by 11am i take it off the charger 7-8am .. it started to "weaken" after i downloaded a ton of apps i leave wifi on and 4g off but it also depends on your signal strenght at home it will kill the phone halfway thru the day because i have one bar
This is my 4th note. The 3 I had previously the battery lasted a long time. I kept the same battery from the first one in all three exchanges. I took the new battery for this fourth one. Could this battery be a bad one or should I return the phone again for a 5th time. I don't wanna take a chance getting a phone with the problems I had on the other 3.
Just looking for some opinions

Good Lord, 3 exchanges!

I ran my batt that way once and I'm getting 18 or so hours per charge (depending on how much I play with it).

Reflash your modem, rom, and kernel. See if that helps
I only get about 3 hours of screen time myself. Seems normal for this phone. The huge screen eat up battery fast. Plus if your using LTE, so good bye to your battery.
I don't think you have a bad phone, That's just how it is in my opinion...
so whats your total at the end.. like say.. 5%..?
If you're getting about 3hrs screen time, I'd say you'd be on par with what I'm getting. Some days I can eek out close to 5 hours screen time, usually on the weekends when im at home and on WiFi.

I don't know why you guys are getting such horrible times. With regular use I'm getting an average of 8-10 hrs screen time, depending on what I'm doing. I'm running Saurom RCVI, with Da_g OC Kernel, and tweaked a few of the JKay settings. I recommend charging to 100%, wiping batter stats, and doing a power cycle on it. That's what I did after installing above Rom/Kernel, and battery went from from 4-5hrs to at a minimum 7hrs.

I would like to see a screen shot of that
Fighting battery problems here as well. I'd assume it was normal for this phone, except when I see people posting great times.
1 week old phone. Switched to Saurom yesterday to see if it's any better. Screen regularly at 5%. Usually on Wifi most of the day (and I'm not in an LTE market yet). I set all my synchs (rss, weather) to 4 hours. Others (Twitter) are manual. Only Exchange Email is push.
Using Cpusy & BetterBatteryStats to try to see what's going on. Could be a bad battery - could be that the number I'm seeing is wrong.
Anyway, I'm getting about a 7% drain an hour *with the phone off* ! I'm even rebooting as needed to make sure it's in deep sleep & not 384 (which is very, very annoying). Unplugging the phone @ 7am means a dead battery by 3pm. And if I'm using the phone, it's more like 12-15% an hour (min screen, reading a book). Been charging in the car and at work - whenever I can for now.
Going to try to run some tests on the new rom. Leave phone off for 30-60 minutes & track % loss. Then, maybe put it in airplane mode & try again.
Some weird ones I see to often - Adfree, Maps, Alarm Manager (which I understand can come from almost any of my apps). Oh - tried Juice Defender, no help there either (didn't make any difference at all)
Finally, in the car with Waze (gps), a Podcast Playing, and the screen cranked up for visibility - the car dock/charger keeps the phone about even. On my HD2, a drive to work would charge up like 20-30% of my phone.
Really, really hope I don't need to carry a 2nd battery for days when I can't keep the phone charging.

Finally, in the car with Waze (gps), a Podcast Playing, and the screen cranked up for visibility - the car dock/charger keeps the phone about even. On my HD2, a drive to work would charge up like 20-30% of my phone.
Really, really hope I don't need to carry a 2nd battery for days when I can't keep the phone charging.

How often do you get exchange emails? I stopped using push exchange email as it was a huge drain on the battery with the volume of emails I get...
With this phone the screen draws some serious juice, so if your using you phone in the car with the screen on its using about 950mah of juice, so your car charger will likely only keep this phone from losing power, it may not gain any juice, and it may even loose juice depending on charger power and what the phone is doing currently.
This is also why most of us are seeing about 3 hours of screen on time, as while the screen is on its using probably 700-800mah of power. divide that by the 2500mah battery and you can see why...
You can try other programs to try and help with things like background data, undervolting, etc, but that's all going to have a small effect as the "problem" is the screen, its eats up most of your juice. If you want to save battery you need to go after the big thing, the screen, not the little things. However short of reducing the brightness there's not a ton you can do about the screen. It is a big screen, and it needs big power to drive it.

I get about 5 an hour during the day. Will try setting it to once an hour in my testing instead of push.

I *think* (need to double check) that the charger is putting out 1A. Where did you get the 950m number from? Is there an appx. chart for different levels of screen brightness (how about 50% for example when in the car? oh - and how much lower is the 5% I use indoors?)
Agree, the #1 thing is the screen itself, which is why I get very confused when I have the large drain with the screen off.
I'll also have to try a test today where I turn on my podcast, but leave Waze off - and turn the screen off while it's charging in the car.

950mah is an educated guess. If you have root you can run this in a terminal to see how much power you car charger is giving the phone... (su first)
cat /sys/class/power_supply/battery/batt_current_adc
I usually get about 9100 for a result, which is 910.0 mah. and my phone will charge barely if I dont have gps going (screen on). if screen is on and gps is on the phone will slowly discharge, so that puts the phone power usage at about 900mah with screen on, so maybe 950 was too high of a guess. So when the phone screen is on, your using a ton of juice for such a small battery.
If I use just a podcast app and the screen is off the phone will charge much faster while in the car. If I have google maps running, it stays almost even...
You could even calculate your usage. She how many minutes your were driving with the screen off and the phone charging and note the amount of battery% gained in those minutes. You'd see a huge difference in charging times with the screen off. In my 50 minute commute to work, I gain about 20% battery charging with the screen off... With the screen on, I see almost nothing.
Seems like some days are better than others.

The first week I had my 920 I was lucky if the battery was at or above 40% by 12 noon. The 920 is my 2nd phone line and I am using it mostly to learn WP8, to surf the web some and listen to a lot of podcasts, usually 6+ hours of them a day. The past 4 days the battery in the 920 is showing insane runtimes. It is currently 11:30pm and it has been off the charger since 8:00am, over 15 hours with overs 8 hours of audio podcast listening. The battery is currently reading 61%. I originally got the impression that LTE was killing the battery, but that is no longer the case.
I have a Share Plan with AT&T with 2 phones, a Galaxy Nexus (GSM model from Play Store) and a Lumia 920. I use my Nexus as my main phone line, to access GMail and Google Reader (a lot of Google Reader feeds). The Nexus has been off the charger the same period of time and is showing 41%.
For me wifi destroys my battery for some reason I get 15 hours with wi-fi on or 28 with it off
Interesting, mine will usually run for 24-30 hours before hitting 15%, including regular usage. 4G gives it a whack but generally I find similar to other phones, if low coverage it chews the battery
Reading all the doom and gloom of 4G LTE on various mobile phones, after my 1st weeks experience, I was expecting similar results going forward. But, after 2 weeks of use, the battery falls in line with the results you mention. And, with that I am not complaining.
same situation here.
It looks like the phone needs some days to warm up and get long lasting.
Also I see that wp8 is heavly optimized for background task in order to not consume a lot of battery eg: my phone lasts more than 2 days with light usage.
I listen to podcast for many hours and it doesnt affect the battery that much, in fact I'm surprised by it because I know audio playing takes a load on the cpu.
Mine.. overnight without charge or using the phone it drained from 100% down to 35%. BS
Two words: Background tasks.
Make sure you don't have unnecessary background tasks running. I have less than 5 and my battery runs more than 2 days easily.
How do you kill or monitor background tasks?
I had really good battery time of 19 hours the first day of installing the new firmware, then I enabled bluetooth again and it drains like crazy. its hit or miss but people seem to think that whatsapp drains battery. I personally would like to disable LTE (its really slow in my area) and just keep bluetooth that seems to give me 12+ hrs of battery.

You can block background tasks for 3rd party apps in Settings->Applications tab->Background tasks. There is no way to monitor these tasks because WP OS doesn't offer any such capability.
Unfortunately there is no easy way to block 1st party apps and if they are misbehaving (like sync something over and over), there is nothing you can do about it.
Turn on Battery Saver can also effectively kill all background tasks. But that's draconian. I still would like my smartphone do something in the background for me.
Don't forget, the biggest battery drain factor could be your cell phone signal. If you keep the phone in a fringe area, the cell radio will drain your battery very quickly while try to maintain communications with cell towers. This is outside the OS and you can't do anything about it.
I had a weird battery drain the day after the last upgrade. No apps running in the background BAR the movie that i had paused.. I lost 80% without using the phone in a 6 hour period (post charging). After a reboot it seems ok. Perhaps i should pause another movie to see if it happens again....
I must say that I have mine 2 days and the battery drains too fast... I dont know what to do .. Maybe because its new ? Some one can help me maybe ?

don't judge a phone's battery life until a week later.

My battery is pretty inconsistent. MOST of the time it's awesome, and will last like 20-25 hours without needing to charge, but that just makes it especially jarring when every now and then I go to check my phone at 4 in the afternoon and it's at critical, and I have no idea what causes it.
Plus when it does die I have to put it on the charger for like 2 hours before it will let me turn it on.
I found interesting point in the battery life today, if the screen is off, the battery drain is in the range of 3-4% which is good, however, if the screen goes on the battery drops like 15% in just 25 minutes. After thinking I tried to set the screen sensitivity to normal and it solved my problem. I kept the screen on for more than 45 minutes and the battery went down almost 6% only which is good. I still have to test more to give a concrete evidence.

I usually run a battery discharge app Saturday night. Then a full recharge with the phone off. That usually gives me dependable battery life of about 12 hours a day for the entire week. If I forget and not run the discharger I notice it midways into the week when I only get about 8 hours out of it.
AT&T lumia920:
after updating my phone to the 1314 update, my battery life got worse.
I went from 14 hours per day to only 8 hours.
thanks nokia -_-
note: I was not experiencing any connectivity issues on my phone.
let's see how many people here actually have NFC on and Auto-Brightness on... lol
I used the sleep app last night after charging to 100%, and then I fell asleep with it on.
I woke up to find the sounds still going, and when I checked my phone worried that I killed the charge, I found it still had 92% left. That's impressive.
Awesome first charge.. plugged in Friday when I got it and just now 38 hours later I'm plugging it in. 4.5 hours of screen on at 85 percent brightness.. here and there browsing.. some photos.. gps enabled turn by turn a couple times.. SIRIUSXM for 4 hours at least.. fell asleep both Friday and Saturday night listening to Art Bell.. so at least 4 hours. Outlook checking mail every couple hours. Tested a few games for probably a total of an hour maybe. This is about average use for me. I would say this bests my note2 and that's a lot to say. Will it get better after a few more cycles? This phone is a keeper... loving the knock on/off feature and I'm getting really used to the buttons on the back.
Good stuff man....lower that brightness a little and turn on autobrightness and you'd be getting even better battery life. Doesnt the constant 85% hurt your eyes?
That's awesome. Battery life was a big reason I picked up this phone, and it has yet to disappoint. I'm on Verizon, so probably couldn't get the Nexus 5, but even if I could I'd probably go with the G2 for the battery. I like a nice bright screen as well
I took the attached a couple if days ago. GPS off, mobile location on, 65% brightness baseline with auto on. Mostly web browsing, with about an hour of talk time, and 3 hours of audio playing via Bluetooth. The battery really is fantastic.
However, there is something that can get stuck and prevent deep sleep causing excessive idle drain. Its happened to me twice now. A reboot clears it up, but I haven't tracked down the culprit yet to prevent it entirely.
Anyhoo, pics below.

Ive found 3 culprits for idle drain thus far:
*backup* - disable backup/ restore in global settings
Nlpwakelock - disable wifi/cell gps assist in global settings, and history anf reporting in Maps
CarrierIQ - disable it as per instructed in the carrier IQ thread

This was from my third charge. Gets better every charge. Basically full stock only debloated.

pretty insane results.. looks like it only gets better! On my second charge now.. still showing 100 percent after a few hours.. very little use though.

I found it takes a lot to get thought that first one percent. I had the screen on for 45 minutes before I dropped to 99% the other day. I'm starting to think there is something up with the battery gauge.

G2's battery life is very awesome...I got 6 hrs around screen on time for stock rom.
I believe if we get more tweaks, rom in future, it will get even better!

No... You're just using an awesome phone!
Yea the battery seems great when you don't touch the device but try playing a game for a little bit . Candy crush crushes ( ? ) my battery to hell.
