[LG Nitro HD] bmxant:
I've been researching this phone for the past couple days so far. From what I've read, the battery life is above average (12-15 hours on medium usage)

Here's the battery information that was listed for the AT&T Galaxy SII

Taken from Samsung.com on September 2nd

Samsung Galaxy SII AT&T Battery

Standby time: Up to 250 Hrs*

Continuous usage time: Up to 3 Hrs Talk*

Thoughts?
[LG Nitro HD] Aphorism:
Above average my foot. Refer to "LG Nitro HD" thread in Android General.

Also I have no idea why you mentioned one phone and posted the specifications of another.
[LG Nitro HD] bmxant:
I posted the battery life of the Galaxy S2 for a reason.

The LG Nitro specs tell us that the battery life is only 3 hours for talk.

The OLD Galaxy S2 specs told us that the battery life was only 3 hours for talk as well.

But was it true? No.
[LG Nitro HD] Aphorism:
I used the LG for a week and a half. At the beginning, battery drained 20% per hour. After a week, battery would drain 10% per hour. But this was by no means constant. I can tell you that I would get up sometimes, unplug my phone, leave, and in 5 minutes lose 5%. It was very unpredictable, and not even dependent on usage.
[LG Nitro HD] mgoblueno1:
Was this after continuous use or like standby? Also, were you able to get through a typical day without recharging?
[LG Nitro HD] saywhat4118:
Well I have the phone right now so ill test the battery and see how it is. It seems fine so far, screen is amazing with a little banding but nothing terrible like the issue Skyrocket is going through . If it wasn't for this phone's screen it would have been in my trash bag.
[LG Nitro HD] totaltoanage:
All day Wifi on and LTE turned off, I got 13 hours at 15%.

Im rooted on setcpu min 192 max 1.5 ondemand with screen off 192 profile. (Medium usage)

Im going to try to turn on nothing but LTE tomorrow.

Starting to like this phone more and more, def need some custom roms asap.
[LG Nitro HD] gordec:
I go about 14 hours before hitting 10%. That's with LTE, GPS, BT on at all times with low medium use.
[LG Nitro HD] dalamchops:
Mine just died

18 hour up time

2 hour screen time

LTE all day in ATL (Hit 57/10 just now in Duluth, gA)

I'd say it lasts a full day with moderate use... maybe 12 hours with a heavier day.
[LG Nitro HD] akfritz:
Is there anyway to turn LTE off?

I'm in a HSPA+ area & LTE is not quite here yet.

I hear on lots of LTE devices that battery life problems are from when the phone is searching for the network all day and it's suggested to turn it off if not in the area.

However I can't find the setting to turn specifically LTE off and leave HSPA+ on the Nitro.

Sounds like my battery is dying a lot quicker than the rest of yours, and that's after I've rooted, reset to factory defaults, removed bloatware, and using SetCPU, Green Power, and Go Launcher.
[LG Nitro HD] gordec:
I don't think the current stock Rom/kernel has that option. I tried to go into Phone info through the *#*# commands, and there is no option for switching radio bands.
[LG Nitro HD] netnerd:
if you "at work" and dont need your push emails, you can just disable data to save some battery.
[LG Nitro HD] rsohne:
Can't take credit for this but its pretty much the same setup used to shutoff LTE

Settings -> Wireless and Networks -> Mobile Networks -> Access Point Names -> Menu (Add new APN)

Name: HSPA+ (can name it whatever you want)

APN: phone

Proxy: leave blank

Port: leave blank

Username: leave blank

Password: leave blank

Server: leave blank

Mmsc: http://mmsc.mobile.att.net

Mms proxy: proxy.mobile.att.net

Mms port: 80

Mcc: 310

Mnc: 410

Authentication type: none

APN type: default,mms,supl,hipri (no spaces)

Then Menu and Save. This should let you have a new APN that will refuse to connect to LTE when it is not needed and has personally saved me tons of battery. You may have to put the phone in to airplane mode or sometimes reboot to get it to latch on to the new APN.
[LG Nitro HD] 8mileroad:
Not sure if I'm understanding this correctly, but will this just not look for LTE and save you battery even if LTE isn't available near you, or does it just deny LTE when it finds it so you'll only save batter if you have LTE?
[LG Nitro HD] netnerd:
if you use old apn: phone

it won't allow you to connect to lte network, so why would phone keep searching for LTE?
[LG Nitro HD] 8mileroad:
I don't think you understand me and I definitely don't understand you.
[LG Nitro HD] akfritz:
Ok, so it looks like the only difference between your settings and the preloaded ones are the "phone" instead of "pta" under the APN section.

Thanks a lot for the help, i'll give it a try over the next few days and see if it helps out my battery life.
[LG Nitro HD] dalamchops:
did a full drain last night, recalibrated this morning, and i'm at 18hrs with 2 hour screen time, and still @ 36%, so definitely better than yesterday.
[LG Nitro HD] rabbivj:
I use Green Power, that app seems to help...tho im using this on my cappy...looking @ prolly the nitro hd soon.
[LG Nitro HD] radon222:
If any of you are on the grandfathered "unlimited" plan...keep this alternate APN setting in easy reach. It will become really handy when you get the dreaded "5%" SMS from the dark overlords ;-)
[LG Nitro HD] blopez24:
lol i got that text the other day and was wondering what it meant
[LG Nitro HD] radon222:
In case you haven't figured it out yet. Your LTE data either has been or soon will be Throttled until your next billing cycle.

But if you set the alternate APN that uses only HSPA+ you'll at least be back up to reasonable data speeds. :D
[LG Nitro HD] diamondscar:
I was messing around with the phone the other night and looked at the "gestures" section of the settings. Generally I think they're useless, but I thought about it and the phone would have to be reading every moment to analyze gestures. I would think this would be a big battery drain so I turned it off.

After a root, hard reset, debloat and battery calibration (as well as several full charge/discharge cycles), my phone appears to have massively improved battery life while in standby. The display and voice calls still take up a lot of power, but I hope to have battery use stats to post later on.

What's a battery calibration?

[LG Nitro HD] s3v3n777:
Hey guys, I finally made the switch from an Iphone to Android (couldn't be happier) and I decided to purchase an LG Nitro. I was on the forum for a bit looking to see what people were getting for battery life. Having used the phone for over a week, I can give some feedback to some who may come here with the same issues I had. First, let me begin by saying that screen was beautiful (yes, was...I no longer have the phone). Secondly, under what I would consider light-medium usage in an HSPA+ area I was pulling about 12 hours to reach 10%. Now, 12 hours may seem like a lot but my Iphone easily would make it all day with the same usage. Perhaps I was spoiled from the Iphone, from what I hear they are great with battery, but those 12 hours on the Nitro weren't cutting it for me. I simply couldn't be attached to a plug. Watching a video would drain battery at roughly 1% per minute. In fact, I got so frustrated I decided to do some heavy usage (watch youtube, and browse the internet) and it died within 4.5 hours. I even drained the battery twice and did a full recharge to try and break it in. Nothing helped. I dimmed the screen, installed juice defender, killed any running apps religiously, nothing helped. :(

I know it seems like I'm bashing this phone, so let me give some perks...on standby this phone could last forever. It barely drained. My biggest power consumption was the screen. In fact, with the screen off, and not browsing the internet and using it as a "dumbphone" (text and calls) this thing would go over 24 hours.

So, lets wrap this up. This is a beautiful phone. Felt incredible in my hands and the screen was to die for...but I couldn't live with that battery. I switched over to the skyrocket and love the battery life (thats for another thread) but yes, I miss the amazing screen from the Nitro. :)

One more thing, once I made the switch to android, I'm never looking back at Apple baby. :D
[LG Nitro HD] slatestud:
Wow. I could not agree with you more. Honestly, I felt like I wrote this.

I also switched from the iphone to this and I am loving android.

The screen on the Nitro is amazing. I 100% agree that the battery does not cut it. The battery itself is pretty good. (calling/texting/pandora/music/ or anything with little screen use this phone lasts for a long time) using the screen however will eat the battery.

I will most likely make a switch to a different android phone soon.

The phone is still VERY good, but i need a phone that can last me a day.
[LG Nitro HD] akfritz:
How much more life do you get on the skyrocket vs the nitro? I'm in the same boat, don't want to switch but the battery life is a big issue. Phone arena gave a head to head of these devices and claimed 12 hr medium use on the nitro vs 14 on the skyrocket... If all I'm going to gain is less than 20% improvement than I'll stick with this for the screen. With lte coming to my area soon I don't want to be stuck on a 2008 network in 2013 so unless at&t unveils another device between now and Jan 4th it seems like these phones are my only option.

I'm holding out for the full duration of the return window either way...
[LG Nitro HD] dinan:
This is a little scary...

http://blog.gsmarena.com/lg-nitro-hd-completed-our-battery-trial-here-are-the-results-video/
[LG Nitro HD] Namuna:
Generally speaking, that is indeed some troubling info. BUT...

There's some missing information there. How were the tests run? Like when they tested Video playing. did they turn off Wifi, GPS and put the phones in Airplane mode so you KNOW you're looking at the actual battery drain by video (and not also the radios and sensors?).

Here's another scenario I would counter-argue with... I'm sure GSMArena used the bone stock versions of the different phones tested, so then all of the extra AT&T bloat that's on the Nitro would've been doing whatever it does in the background (we already KNOW that bloat contributes to general slowdowns on the Nitro). So I'm going to go ahead and blame this bloat as potentially hurting the Nitro's battery longevity as well.

AND, I'm going to compound that accusation and blame with the notion that AT&T's 4G LTE isn't available everywhere yet, so whoever was testing might be in a "dead zone" where the phone is constantly seeking a non-existent signal (like what happens when you're in the subway).

Maybe I'm being overly defensive, but my gut feeling tells me a LOT of the panning the Nitro is getting is because of the pre-installed crap/bloat and with just a little tweaking most of the concerns are completely addressed.
[LG Nitro HD] spaceboyusa:
Not only do I echo the sentiments of how sucky the battery life on this phone is in general, if there are any road warriors out there considering this phone, stay away. Here's details on my yesterday trip and battery results:

1. Pull up at gate at SFO and turn on phone: 98% battery (charged it on plane)

2. Foursquared from SFO, and on BART, all the way to Powell St. station (maybe a total of say 11 checkins)

3. Checked email twice, both personal (hotmail/gmail) and work (via Dolphin HD/web email)

4. Walked to Starbucks just down from the Ritz Carlton, sending about 10 texts and taking one 10 minute work call

5. Battery status at Starbucks: 50%; total elapsed time: 1 hour

Same crappy results for the Broncos game I went to on Sunday. Left the house 100% charged...by the time I got to the stadium via Light Rail an hour later, I was down to 55% simply by using Foursquare, sending a few texts, posting one FB status, and taking a few pics. By the start of the third quarter, after taking three 2-3 videos and say 10 pictures (couldn't call or send texts as at&t service in the stadium was mostly not available), the phone was at 10%.

I've had the phone a week...I've hard reset...I've drained and recharged...I've removed unnecessary apps...no help. I really want to like this phone but as someone that travels a ton, no way I'm sticking around to "wait this out"...too painful.
[LG Nitro HD] Namuna:
Wow spaceboy, I can certainly feel your frustration! That DOES suck!

Can you give a rundown of what's sucking up all your juice from Settings>About Phone>Battery Use?

I'd imagine the top offender is 'Display', but it would be interesting to see if there's other offenders in there.
[LG Nitro HD] spaceboyusa:
From what I remember, display and wifi have always been hangin' around the top three. As a result, after the Broncos game (and thus in effect for my trip to SFO), I started turning off things like wifi or GPS when I know I don't need them. Quite honestly, this has had little-to-no effect on the battery. As for the display, I have the Brightness set at auto, and have been keeping an eye on it by unchecking the Automatic Brightness box at various times in the day/night, and have yet to see it exceed 35-40%.

What bothers me most is that I even have to worry about/mess with this stuff just to survive a 2-3 hour block of time with moderate usage. I understand that LTE and the display puts even more pressure on the battery but still...at this level, simply more hassle than what it's worth. I want to keep LTE and 720p but the Nitro's "operational penalty" (if you will) is simply too much to pay.

I'll keep messing around with some settings and maybe even try a root (as a noob I get a little nervous about doing that but anything's worth a shot) to see if I can turn this around. In addition, the at&t store said they can always order a new battery for me to try so...not ruling that out either.
[LG Nitro HD] dinan:
You could argue this from any phone's perspective. For the video tests the phone is in airplane mode. I've somewhat confirmed their test with my Galaxy S2 so there's no way I could really get 8 hours of video while still on 3G. The video test is the one I usually look at the most since it's independent of network variables. It just shows the screen on the Nitro really sucks a ton of power... looking forward to the Galaxy Nexus battery test though since that also has a 720p screen.
[LG Nitro HD] scott0:
i'm in downtown los angeles, lte being turned on any day now so i'm trying to get a feel now for how the battery does without it. music is going pretty much all the time.
[LG Nitro HD] s3v3n777:
Under heavy usage my skyrocket gets an amazing battery life. I've been downloading apps, streaming music, reading web pages, and texting all day. I charged my phone last night at 9pm and it is currently at 25% with a good 2 hours left. It is currently 1:39pm here. So I'm looking at about 20 hours of use with medium to heavy usage. My nitro was dying in 4 to 5 hours with similar usage. Yes, it was that bad when the screen was on. Now, to be fair, my nitro would last me longer on standby than this phone, at least that is what it seemed like. However, I use my phone a lot so the nitro just didn't work out to be the phone for me. I'm currently in love with my white skyrocket. :p

Now, I respect those of you that kept this phone and can work with the battery, I just shouldn't have to tinker with something for it to work well. Then again, that screen definitely worked really really well.
[LG Nitro HD] Namuna:
Skyrocket and Nitro share the same Snapdragon APQ8060 chipset and the batteries are only 20mAH difference and both are 4.5" screens.

So assuming the rest of the hardware being the same, that's painting a mightily negative picture for the AH-IPS screen's power suckage.

So is it a matter of overworking the GPU to fill all that 1280x720 lusciousness? Maybe the brightness too?

Lucky for me, I'm usually never too far or long from a power source, so battery longevity isn't too much of a concern. MAN I want my phone NOW so I can for myself what's up!
[LG Nitro HD] s3v3n777:
You're right it does have the same processor just the different screen. I don't know if its the screen or what but there is a huge difference in battery life. The display was always the worst battery user.
[LG Nitro HD] dinan:
If the screen was the main factor for the battery differences between the two then shouldn't talk time be similar? The Skyrocket claims 7 hours while the LG only 3? They both claim similar standby times at ~250hrs. Seems like LG did a poor job optimizing their phone...
[LG Nitro HD] s3v3n777:
Actually, I just noticed that you wrote about having a power source nearby. I also have one near me all the time but I shouldn't need to plug it in all the time. Hence, the term portable phone. It lacks the portability of not being connected all the time.
[LG Nitro HD] karkas_:
Another iPhone to Android convert here. I can't say I'm loving android from the switch, but that's for another post.

I have to echo the other people here, the battery life has been a huge blow.

I have to keep mine on the charger constantly. Mine goes from ~100->40% in ~3 hours if I seem to do anything with the phone. At this rate, I'm not sure if I can stay with this device.

I tried some of the battery savers, but those seem to be interfering with the charge cycle, because I left mine to charge overnight 2 nights ago, and when I woke up it was only at 35% and was super hot.

I uninstalled those, but I still have to recharge around lunchtime if I want this to make it 'till bedtime tonight. I have ~2.5 weeks to return it, so I'll wait and see if things improve.
[LG Nitro HD] s3v3n777:
I never had charging issues so thats rather odd. Charging did take long but it did make it to 100% after a few hours. Maybe its a messed up battery. Who knows.
[LG Nitro HD] karkas_:
I was thinking the battery may be at fault, but I'll see if the problem returns in the next week or 2 without the battery savers on board.

FYI they were Juice defender and Battery Dr. Saver
[LG Nitro HD] s3v3n777:
Odd. I used juice defender and had no issues. In fact, I still use it on my skyrocket now.
[LG Nitro HD] karkas_:
I don't know for sure, I'll report back if the problem returns after the uninstall. 2 days now with no more charging issues since removal though. I dunno.
[LG Nitro HD] scott0:
i installed juice defender elite and set it up last night, here is a before and after for the same period/usage. (my morning routine)

it's important to note that i had the phone plugged into my computer and charging most of the time in the before.

impressive.
[LG Nitro HD] Namuna:
While on the hunt for availability of spare batteries for the Nitro (model BL-49kh), I hit on the forums at LG and in particular this thread about the bad battery drain:

http://www.lgforum.com/forum/boards/general/lg/topics/nitro-hd-battery-life

So there's apparently someone from the LG team actually looking at it...I'd say if anyone has more to add, that thread would be a good place to raise awareness.
[LG Nitro HD] red_solo_cup:
Scott -

Which setting do you have juice defender on?
[LG Nitro HD] s3v3n777:
My only thing with this picture is that the display was the main killer in picture 1 while it wasn't in picture 2. As far as I know juice defender will not help with drainage caused by the display. From personal experience, the biggest drain on battery was the display on the phone.

I'm more interested in seeing the screen below to see how battery drain relates to screen time on.
[LG Nitro HD] red_solo_cup:
Exactly. Every time I look at power usage, the screen is the biggest offender. Therefore the second screen capture is showing the difference between having the screen off and having the screen on.
[LG Nitro HD] dinan:
So basically if you wan't decent battery life don't turn on your screen... yea that's not gonna fly with most people heh.
[LG Nitro HD] scott0:
see pic below :-)

also, i had the name of the app wrong, it's juice defender Ultimate, not Elite.

the version of jd installed on this phone has functionality to adjust the display, see pic below

like you, i was concerned that this app would impact my enjoying this wonderful display but now that i am actually using it, the app has little to no impact on my usability, if i am not using the screen/phone, the screen turns off. when i need to see the screen, it turns on.

i like that.
[LG Nitro HD] scott0:
screen cap of most of JD's display adjustment features.

:-)
[LG Nitro HD] akfritz:
cool, your pre/post shots were convincing enough I picked up jd ultimate... Thnx
[LG Nitro HD] s3v3n777:
So wait, this basically turns off the screen just like the OS system does? Im sincerely not asking to be a smart ass, I'm just trying to find out how this is different than setting the screen display timer to really low on our OS. If it does help to save battery by having the display somehow suck less juice then I'm down to use it on my skyrocket to get into the 2 day battery range. My problem is I tend to always be on my phone browsing the net or fiddling with stuff, so I need my battery to make it with the screen on. So, let me know. Thanks.
[LG Nitro HD] scott0:
i don't really understand what all it does, tbh, i got the impression from those features shown in the screen cap that it works a lot on brightness levels and also how the light sensor works in addition to when the display turns off.
[LG Nitro HD] scott0:
seems the cpu draws a lot of juice as well.

that dramatic drop at the end of the 10 hours was when i played the 36 minutes of drag racing. :eek::eek:
[LG Nitro HD] V@no:
Can someone please test it with pandora radio and/or sportypal?

These are two apps I use 8 hours a day and my current atrix 4g is able to last about 5-6 hours with both of these apps running...Skyrocket would die in 3-4 hours with the same setup, but I didn't calibrate the battery there.

Thanks.
[LG Nitro HD] s3v3n777:
Well if Google music is any indication, it would do well as long as that screen didn't turn on. Whereas the skyrocket has a pretty steep (compared to the Nitro) battery drainage curve when the screen is off, the Nitro's curve takes a nose-dive once the screen is turned on. Additionally, really 3 hours for the skyrocket!? Holy crap. I hope its just the sportyapp and not Pandora.
[LG Nitro HD] manther:
This is the same snappy 1.2 overclocked to 1.5. Since you guys have root, has anyone thought about knocking the clock speed back down to 1.2 to see if the battery life improves. I assume most people are buying this phone for the screen and the LTE, not the CPU. (If you wanted an at&t phone with a bad ass cpu/gpu the original SGS2 is the way to go). Just an idea. Still watching this forum until my upgrade at EOM.
[LG Nitro HD] hashhash:
i have used alot of roms on SGS and including regular eclair/froyo/gingerbread and the battery usage was always horrible on official releases. Custom modems and future Roms will hopefully make the battery life alot better on this LG optimus LTE.

I am going to try and freeze the LG interface/launcher and see if that makes a difference coz i am using ADW right now.
