[G2 General] *Omnipresent*:
Two quotes from AnandTech's G2 review, explain the G2's superior battery life.

"In addition the G2 has a few unique power saving features of its own, including display GRAM (Graphics RAM) which enables the equivalent of panel self refresh for the display. When the display is static, the G2 can run parts of the display subsystem and AP off and save power, which they purport increases the mixed use battery life case by 10 percent overall, and 26 percent compared to the actively refreshing display equivalent.

"The G2 has a fairly sizable 3000 mAh 3.8V (11.4 watt-hour) battery which is stacked to get the most out of the rounded shape of the device, and utilizes LG's new SiO+ anode for increased energy density compared to the conventional graphite anode".
[G2 General] rkaria1970:
Sorry for my noob query, but having task manager clearing ram frequently should improve battery life, how come setting it at 3 days ?
[G2 General] gm007:
Go to task manager settings.
[G2 General] rkaria1970:
Yeah, i just saw that settings, but the guy above just commented that he keeps the auto clear settings to 3 days to improve battery life,

so my question is 12 hours or 3 days ? :confused:
[G2 General] G1_enthusiast:
lol some of you guys are just benching for battery rather than enjoying a smart phone hahah
[G2 General] gm007:
So we came together from XZ :p
[G2 General] G1_enthusiast:
Haha you jump ship too huh?
[G2 General] purpleraintoxicity:
you ate wrong

if task manager closes apps more frequently, the app will try to reopen, and that's the battery drainer

Mirror Link Cert Test

Hi there,

got my G2 on monday, it seems the battery is very powerful, but not as good as anyone mentioned.

I installed Better Battery Stats and I found a really big battery drain from "MirrorLink Cert Test".

What is this MirrorLink Cert Test and do I need this or can I freez this App with Titanium?
[G2 General] sil0:
From what i can see so far, it seems this application MirrorLink Cert Test is related to linking your phone applications to your car..

See more details here: http://xdaforums.com/showthread.php?t=1307005

Quote:

The idea is to enable an ecosystem of phones, cars, or head units, and applications that can work together, essentially porting the application to the car. The technology is 14 months old, and the CCC hopes that MirrorLink will be a standard feature on cars by 2014.

End Quote.

Currently it is not something i would use, and the battery usage did seem abnormally high in your screenshots so i have disabled it for now, will see report back any issues.

Anyone know what "Key chain" is? I see that alot.
[G2 General] theartofdance:
What else did you use your phone for mky4b11?
[G2 General] mky4b11:
Pretty much everything. I played driftmania for like 30 mins. Some zombie frontier. Facebook, instagrams, photo editing in pixlr. Camera, Netflix, YouTube, Pandora. Lot of Internet browsing , and tune in radio. Tapatalk, xda. Snap chat, texting, and few short phone calls.

I really don't hold back on using this phone to save battery like I used to on my HTC one.
[G2 General] theartofdance:
That's incredible. I'd never get battery life like that. I don't get it.. I wonder if I have a bad battery or something...
[G2 General] TNT321BOOM:
Coming from the LG Nitro, which had terrible battery (almost the worst in the market at the time) the G2 is a great improvement.

I can last a whole day of heavy usage and end up with 10-15% left.On a moderate day, it will be at 30-40% by the end of the day.
[G2 General] mky4b11:
I have most bloatware removed. Greenify most apps, and I use lux to control screen brightness to less aggressive values.
[G2 General] theartofdance:
Can you explain lux a little bit? I have most bloatware removed and Greenify most apps as well...
[G2 General] mky4b11:
With lux brightness manager, you can link a set brightness setting to whatever lighting conditions you have. I find I rarely need full brightness, so when I'm in a room, I have the brightness set to about 40%, and then the app dynamically adjusts your brightness based on that linked setting you set up.

[G2 General] Zorachus:
I am still running stock, not rooted or ROM'd yet. Right now I am at 8h 29m total usage off a 100% charge this morning. Current battery life is already down to 35%, and only 2h 49m On Screen Time, and I have been on WiFi all day. I have GPS off, sync off, no e-mail or Facebook stuff installed yet.
[G2 General] ac29593:
I'm not sure where all these bad reviews of battery life is coming from because on my phone the battery life is excellent. I get about 4 hours of screen time at a hundred percent brightness plus voice calls Plus GPS and I still don't need to charge it. The phone easily last one day. Charging it is so fast that putting on the charger for 20 minutes gets about 15 to 20 percent back anyway. And just so you know I easily use about 10 gigs a month and data and I'm constantly use my phone so I consider myself to be a mid to heavy user.
[G2 General] crashN2u:
That's odd. I am not rooted and i got about 16 hours with close to 7 hours screen on. Half of that time was LTE. Today I'm on track for 18 hours and I have 4 hours screen time with 54% to go. I did however, disable all the battery guzzlers and lowered my screen to a maxof 60%

Something is definitely eating away at your battery. If not, you got a defective phone.
[G2 General] XxJustaSexiBoyxX:
Rooted att g2 running stock rom with several things disabled, such as carrier iq and bloatware. Havent been really impressed with battery usage until the past 3 hours or so. It always lasts me a day, but so did my s4 and i find them very comparable. However, tonights usage while at home and on wifi has been amazing. Wifi on, gps off, bluetooth off and brightness going back and forth between 15 to 60%. Getting more than an hour On screen time for every 10 % used.
[G2 General] tupacpsp:
I get almost two days out of it,
[G2 General] sandeep20064096:
How much time it will take to fully charge from 0 to 100 % with stock charger
[G2 General] ock:
Slightly over two hours.
[G2 General] theartofdance:
I've realized that.... My battery life is GREAT when in standby. Overnight, it only loses about 3%. The problem is whenever I'm using it, the battery life goes down SO fast. The chart slopes down like a plane that's about to crash. Everyone else on here is getting some great screen on time, and I get lucky if I hit 5 hours. And it sounds like some of y'all are really using your phones for a lot. I'm a pretty heavy user, but I wish I could get a little more screen on time ... :(

[G2 General] simorangkir_dcs:
I feel for you bro, you might have a bad device there. You should return it and have a new one.

I am having the best battery life so far. Probably will hit 6 hours screen on time, and that's with all sync on, whatsapp, Facebook, location on, etc. For a guy coming from Nexus 4 this is a real significant upgrade. My N4 screen on time is 3 to 3,5 hours with less standby time.

And another good thing is devs are starting to come in. Things are looking up! :):):):)
[G2 General] gm007:
This phone is crazy :D

40 hours unplugged and 6:22 hours screen on time.
[G2 General] theartofdance:
I should just unsubscribe from this thread cause it's frustrating. Lol.
[G2 General] MoreGone:
I just wanted to chime it

This phone has totally amazed me with its battery life. I don't care if this isn't the thinnest phone out there, I can literally stream music all day, do my normal routine and not have to plugin at work.

I did a 6 hour drive from CA to AZ streaming music, talked on the phone, light browsing (driving) and did some navigation. When I got home I still had 50% battery.
[G2 General] nagel:
How come some of you have wifi on all the time? Don't you turn it off when out of the house or office? Does leaving wifi on even when not using the phone use less battery as compared to leaving it on data?
[G2 General] wargreymon89:
I thought your times with 80-100 hours were too good to be true, had to try this by only using my phone a little every day. Settings in the pics, Wi-Fi always on, sync always on, I used it for browsing (Naked Browser), twitter, camera and mail.

I did remove MTL, Google+ and Chrome with titanium and I also removed Google Search and Play Services and reinstalled them from the store.

When it was in Deep sleep it drained about 0.3-0.4% per hour. When I was reading articles I could get up to 10 minutes per 1%! (GRAM loves not scrolling). When I was changing pages a lot I usually got 4-5 minutes per 1%.

Pics so it did happen:

Yes, its in Swedish, Suck it up, buttercup.
[G2 General] theartofdance:
So... You just left your phone alone for majority of the time? I can't do that with my phone... Haha.
[G2 General] bd1212:
From the looks of it, he was using it quite a lot. 6 hours of screen-on time is a lot of use.
[G2 General] theartofdance:
Turned Google now location services on. These are the numbers I got. So sad because I would love to be able to use Google now...
[G2 General] Timger:
How do you guys get such a great battery life?! Right now, I had my phone off the charger for 4 hours. 1:10h screen on time, a couple of calls, and 63% back on the battery?!

What can I do to get a better battery life?
[G2 General] dukat0s:
d802

i got g2 for 1week +few days now and i must say the battery life is getting better and better after a full charge. i used to see 6.30 screen on time but now i see 8hours+ for fun. i use navigon a lot i stream episodes a lot and chat with friends all time through facebook
[G2 General] theartofdance:
That's insane. Wow...
[G2 General] magestic1995:
Hey guys,

So I have been trying to figure this out, why are my battery stats so weird. I bought the phone about 5 days ago and have charged about 2 times with a few like 10-20 minute charges. I love my battery life I am not complaining in the slightest, I loose about 30% for a days use, But I wanted to know what yous thing causes my screen not to be the largest battery absorber as per usual.
[G2 General] LittleH79:
Your CarrierIQ services are constantly hogging cpu etc.

Do a search for disabling them, I don't have CIQ here so don't know where the solution is where to disable them.
[G2 General] KrisisTP:
I used to turn wi-fi off when I could not connect to a wi-fi network (such as at work), and the difference between having wi-fi on when unable to connect and wi-fi off in those situations was very noticeable on my battery. That was on my poor Thunderbolt, and my OG Droid before that. Not so with this device. I have noticed no difference between leaving wi-fi on or off on the battery usage. I consistently get 48+ hours of usage on a charge with 6.5+ hours of screen on time. The battery life is crazy good.

Running Malladus 1.1 atm. Might upgrade to 1.8 or whatever sometime, but I have absolutely zero complaints about the function of this device, and I am glad many others get great battery life on their phone finally. I hope the rest of you reporting lesser battery life find what it is that is keeping your phone from running longer.
[G2 General] theartofdance:
I hope I find it too... I'm not disappointed s much because it's clearly better battery life than my previous iPhone 5. But I'm getting HALF the battery life of what everyone in these forums are getting... I'm confused. In starting to think it may just be a battery problem...
[G2 General] nagel:
I have been able to get 5 hrs but not 6hrs so far. I use lux for auto brightness and so bluetooth in the car for podcasts.

I tell myself that those of us who get insane battery life is just lowering brightness to a less than enjoyable level. Makes me feel better :D
[G2 General] Timger:
Can some of you with +6h screen on time please write a mini guide what you have done, removed and so on, to us with only 3:30h screen on time? Thank you :good:
[G2 General] oliver2ooi:
I don't agree with you. I'm also one of the G2 D802 users who get half of what most users post here and I rarely use over 0% brightness!

I'm rooted, greenified some apps, frozen others and uninstalled what I think don't matter to my phone. I'm gonna wait a month before sending my phone back where I bought it to get the battery changed

Battery life is what i am going to talk about, i am on CleanROM XE 1.1 with in my at&t G2. This phone doesn't require much battery power, i really wonder why.

No matter which phone i keep it in 85% brightness, do data tethering(30 minutes everyday), Wifi or 4G(always on 24/7), gmail, mail, whatsapp, Hangouts(gtalk), textplus, google voice, google maps (use it from time to time) are always running. I go to work at 9:00 AM and return by 7:00 PM.

Starting from 9:00 AM at 100% battery

Galaxy S3 --40 to 60% battery remaining by 7:00 PM

HTC one -- 40 to 50% battery remaining by 7:00 PM

Galaxy S4 -- 40 to 50% battery remaining by 7:00 PM

LG G2--79% battery remaining by 11:59 PM

I am not making this up or trying to rub it against anyone or exaggerate. It's unbelievable. Could be the ROM(CleanROM XE 1.1 ) highly optimized for the battery.
[G2 General] Damasterjj:
sometimes this phone last me 4 days in a single charge. so 25% per day is more than possible
[G2 General] gm007:
I am getting 6+ hours, i have the brightness at 60% auto and i think its ideal for indoor outdoor.

Most of the time i am on 3g or wifi.

When on wifi the battery will last longer than 3g.

What i do is browsing(boat browser),some YouTube,few calls,whatsapp,lot of xda,taking some pics with the camera,downloading from playstore....I don't play games.

You can check my screenshots 2-3 pages back and this from today,14 hours unplugged.

On a good day, I get just under 3h screen on time, in a 24th period, and then my phone is at 5%.

I have tried a lot, greenify apps, lower my brightness, use a 2x battery saver app, that turns off data, when the screen is off and so on.

I hope you will write a little something, so hopefully us with a bad battery, can unleash the full potential of this monster

[G2 General] GeneralRam:
I had to go stock as my battery life was terrible on CM
[G2 General] digitard:
Extremely impressed with the battery life. The below was taken after a full day.

As you can see by the usage it was off the charger all day long. I used it for about 3hrs. Mostly text, a few short calls and some browsing on WiFi. Minus maybe 2-3 email checks all usage was on WiFi so minimal LTE drain obviously helped.

Its still impressive to me having previously been an iUser.

Only real tweaking is:

ROM is running CleanROM 1.1 right now.

Using Greenify for saving of wake locks and so forth (Highly recommend)

Almost all data services are on manual sync.
[G2 General] justflorin:
Sure... Here is what I did/do to get 5-6.5 screen on time. Sometimes that's achieved over 3 days or over one depending on work of course :)

First of all cleanrom 1.1, disable the ciq stuff, get greening and just close everything you don't want turning on on its own so eBay, sports, news typing like that. I went a step further personally and under the LG task manager I disabled almost all services that I don't use every day. Email, text, voice mail through gvoice, greenify itself, system tuner, bbs, calender, contacts, Google keep, and maybe a couple others I left alone but everything else was checked.

I reboot after almost every charge, but thats me... Takes 20seconds, why change something that's working.

That's about all I do, if anyone else wants to chime in go for it.... Oh yeah, I used titanium to delete the Google system apps and reinstalled them myself... Read that somewhere, probably handles resources better not sure.
[G2 General] Vysin:
What does the ciq stuff do?
[G2 General] crashN2u:
How long have you had the phone, has it gotten worse, or better since you got it?

When I originally got mine, I was draining the battery in about 6-10 hours, 5-7 hours screen on time. I thought I had a defective phone, turned out I was just playing with it too much. After I tweaked a few settings and got into my normal routine, I started to see the battery lives that everyone else was posting. The other day, for example, After almost 7 hours of use and 45 minutes of screen on, I was still at 95%. By the time I plugged it in for the night, I still had 46% after 16 hours and about 3 1/2 screen on.

This is how mine is set up if you want to compare.

- Stock system, no root, no mods

- Screen set to auto, baseline 60%

- WiFi always on

- 4G signal everywhere I go

- GPS off unless needed

- Location services on

- Vibration on for all alerts

- Tactile feedback on

- 4 push email accounts

- Disabled all Verizon bloatware

What I tend to do after I'm done using my phone, is hold down the home button to bring up a list of active tasks, I use the "clear all" and put it away.

Today was heavier than normal for a work day. I'm at 29% after 14 1/2 hours with 3 1/2 screen on. I tend to average about 16-17 hours with an expected 22. 5 1/2 - 6 1/2 screen on.

Good luck with finding out your issue.
[G2 General] iamacronym:

i've only had the phone for 3-4 days now and the battery was draining pretty damn fast. like i had 2.5 hours of screen on and a dead battery after about 12-14 hours of total use. I have to see how it is over a longer period of time thogh
[G2 General] zxrax:
Man some if you just don't use your phones very much... Forty hours and under 1.5hrs screen time? In that amount of time im at more like 7 hours screen time.

Fortunately I still get about 50 hours of life out of my phone, but to me that's phenomenal. My iPhone 5 was dying before I got home every night (after school and work I end up back home around 11pm) and this phone is almost always at 50% battery or better by then.
