Something to be aware of: The AnandTech review didn't have an LTE version of the G2. So the battery life results they got should be taken with a grain of salt.

Google services will stop draining your battery if you disable the 'find my phone' feature. Trust me, it'll help A LOT!
[G2 General] zxrax:
Where is that feature?
[G2 General] jonathan3579:
Go into the green Google Settings app. You'll see it in there. :) You won't see Google services taking any more of your battery life after that.
[G2 General] mahendra1020:
Am loving it.
[G2 General] Semantics:
Thanks for this, but I don't see a "find my phone" feature in Google settings.
[G2 General] jonathan3579:
I'll try to look up the exact name of it. I'll report back here in a few. The short of it all is that it's reporting your location constantly for the service. Maybe I missed a sub section in the app? It has to do with location.

Edit: Okay, it's specifically called Android Device Manager. I wish I had a phone in front of me so I could give you a more specific spot.
[G2 General] Semantics:
Thanks, turned that off. Apparently I have something called IMS Service which has woken my phone 254 times since its been off the charger. I'm going to investigate this and find out what's going on. Its not even Google Services that are bad, its Android System number 1, and Android OS number 2. Need to figure this out, battery is draining quickly today, it was great yesterday.
[G2 General] jonathan3579:
No problem! I can tell you that IMS Service relates to WiFi Calling. I remember having to deal with this on the HTC One S. Unfortunately, I do not remember what the fix was or if it was something I could do. Hopefully that helps a little though. I do not use WiFi Calling so the only thing I can remember doing myself was making sure it was off.

Great screen on time. No heavy apps? Like video recording or Asphalt 8 game? ))

Mine is constantly getting 5 hours screen on time out of 16 hours of total use. Thats pretty good, cause i use miracast, i play Asphalt 8 and making a LOT of photos and videos.
[G2 General] 903tex:
Using a lot of Facebook app, lte and WiFi on all day. A lot of phone calls., plus texting all day and constant work email. Crazy how this phone does on battery life. I've only gotten similar battery life using extended batteries! But I'm using the d800 att model if that's makes a difference

Best battery after 4th charge cycle...

Coming from HTC one.... that's a great improvement ... HTC one would only around 4h of screen on time with The same partten of setup and usuage ... lovin it...
[G2 General] unlockall.mobi:

[G2 General] vween:
Am I reading that last image correctly? Your phone was awake 99% of the time?

Also, in the third image Setup is at 9h 9m. What is Setup?

Also, you got some carrier.iq running. Not sure about T-Mobile, but on my AT&T that junk is buggy and causes a HUGE wakelock.
[G2 General] oliver2ooi:
What worked for me

I was having battery drain issues or should I say battery calibration problems, because around 10% it used to hold very long.

So I did this method found on another thread :

Charge phone while on for 8 hours or more, turn phone off and charge for 1 hour, turn phone on, wait 2 minutes and turn off, charge for 1 hour.

My battery has improved well. I would post screenshots but I messed with the recovery unsuccessfully which drained my battery by 5% because it freezes
[G2 General] El Che:
Had charged my phone fully, played with it for 15 mins then went to sleep. 7hrs later when the alarm rang the battery was still at 100% :victory:
[G2 General] JohnnyZNN:
From 100 to 99% takes a long time. From there it goes faster.

But still slow compared to other phones.
[G2 General] magestic1995:
Thats what I'm trying to understand I do not get why my phone did not sleep the entire time it was off the charger, also I have no idea what is taking my battery up as setup, its name changes every day, yesterday it was called camera test. Any ideas?

I have the T-Mobile Version and its only about a week old. Running stock all I have done is root and greenify

Edit: Added photos of what is shows under android system/setup
[G2 General] MarvinSpr:
My battery life is great. I'll get 10-12 hours juice with heavy use.

Now i have a custom rom, so i will test out the battery life again.
[G2 General] Timger:
Finally I get better battery life, but I still have a question. The first 50% battery life, I got 3h of screen on time, and 26h standby, and everything was just good.

When it got below 50%, the battery was draining much faster. Right now the phone is on 30%, it went from 45% to 35% over night, and I'm up to 3:30h screen on time, and 37h standby time.

The battery drains faster when I use the phone.

Is that normal?

[G2 General] vween:
It's not normal that you should go from 45 to 35 overnight. You either have a wakelock or you haven't configured the apps you use to not be doing junk while you sleep.

Oh, and yes, batteries on all phones drain faster when you use them.

---------- Post added at 10:22 AM ---------- Previous post was at 10:15 AM ----------

I'm not too familiar with greenify, but maybe it's freezing something that camera test/setup are using and so causing them to wakelock? That's just a guess. maybe disable greenify for a day and see?

Maybe it's time to try a factory reset.

[G2 General] bd1212:
Are you running the latest CM10.2 build? Since I got the phone a week ago I've only been running stock ROM's, but I'd been seeing subpar battery life (barely 4 hours of screen on time with 14 hours of usage). Then, yesterday I flashed CM10.2 and my battery life skyrocketed. I was able to get 6 hours, 10 minutes of screen on with 19.5 hours of usage. That was with 1 hour of navigation which rapidly drains the battery. Had I not used navigation I'm sure I could've gotten 7 hours of screen on time easily with at least 22-24 hours usage. Battery life on AOSP ROM's blows away battery life on the stock LG ROM's.

Can someone help me please

Hi guys i am new to Lg, i am trying to find out how long can my battery lasts, but every time i boot my phone the count starts from that time, so i cant get a real time of battery history. By the way i am using a stock Asian rom, i have rooted it and installed official touch CWM. i have charged my phone like 5 times already and i have had my phone for 4 days. So yesterday i wanted to check how long my battery lasts so i have charged it to 100% and unplugged it from charger since 11.16 am that morning. You see as long i don't reboot my phone the stats are ok, but after i reboot the stats are reset and show only since boot or the last 3 hours. i can't seem to see the whole history since charged i have attached a screen as you can see it shows 81% but usage is 1h 53mins which is not, as i stated earlier i unplugged my phone from charger since 11.16 am and now its 10.46 pm so around 11 hours and 30 minutes of use.

I have found another post suggesting i wipe the battery stats. Since there isn't that option in recovery i did that manually by deleting data/system/batterystats.bin after i fully charged the phone and wiped cache partition, and wipe Dalvik cache.

But after reboot i tried to reboot again and it didn't show my first boot history time, so it's as if the battery history isn't saved or it's reset,

By the way i checked the battery with BetterBatteryStats and it only gives 1 option to view history and thats since boot, but when i did my first boot after deleting batterystats.bin, BetterBatteryStats gave me the option to view since charged and unplugged but not any more.

so far i don't see any other option but to install a fresh stock.

Battery Life with Google Now and Location services

What kind of life are people getting with Google Now and Location services on?

I am getting about 8% an hour drain, very little screen on time (~2 hrs a day). I stream pandora over bluetooth for about 1hr a day.

I am running a stock rom with only the wifi tether and de-bloat scripts installed. This doesn't seem good.

Google services is a known batter hog. Sometimes with it in it only takes 5-10% of battery, but then other times it takes up close to 50%.

I just tried the delete Google Play Services and Google Search with Ti Backup / Re-install from the market trick, I will post back with findings.

Better battery stats shows Wifi is running 100% of the time, even though "Keep Wifi on during sleep" is set to "only when plugged in" and the phone is not plugged in.

---------- Post added at 04:01 PM ---------- Previous post was at 03:57 PM ----------

You are getting much better battery life than I am. I would love to have that stamina. I am running everything, Wifi, 4G, location services, GPS, Bluetooth, 70% brightness (auto). With around 2 hrs of screen on time I get about 12 hrs life.

My One X running the latest VenomRom would get 20hrs with the same stuff turned on and much smaller battery. Somethings not right, but I don't think it's defective HW.
[G2 General] joshwoods:
The main reason I lean toward hardware is that when I bought the phone at best buy, the battery was completely dead out of the box. Took the guy forever to get it running and provisioned. He thought it was odd since most have around 60% battery out of box but wasn't interested in opening up another for me.
[G2 General] Timger:
Hello.

I have noticed something strange with my phone.

I fully charged it 2 days ago. The first night, it used 3-5% over night, that's acceptable.

The next day, in the beginning, I had great batteri life. Got 2 hours screen on time, when I reached 60%. After that, things started to get fast. From 60% to 18% I got 1h ekstra screen on time, with the same usage. When I got to bed last night at 22 there was 18% battery left. This morning at 6,the phone was dead, used all the battery.

From the start, the first 50% battery gives me up to 2:30h screen on time, and then the battery start draining fast, no matter if I use it or not.

I am rooted, have greenifyd almost all apps, turned of location service and so on.

Are there anybody else having the same issues, that the phone is discharging faster, at the last 50%, or could that be a faulty phone? As I wrote, it's have been like this from the beginning

I can confirm that my battery had ~70% when I opened the shipping box.

---------- Post added at 10:19 AM ---------- Previous post was at 10:13 AM ----------

Reporting back after I deleted the Play Services and Google search. The battery drained at the exact same rate (~8% per hr) until it was below 12%.

I put the phone on the LG charger and while it was charging I deleted the hangouts app with Ti Backup. I took the phone off the charger and it drained ~3% per hr while I surfed the web before going to sleep. Put on charger again to fully charge and have been heavily streaming music and ~1hr screen on time. I did not do the restart after charging trick others have mentioned. Battery drain is ~3% per hour, this is satisfactory to me.

To summarize, I run Auto brightness with 70% baseline, Wifi on (not during sleep), Bluetooth, GPS, Gmail and Exchange sync, No Facebook, Location services on, Google now, Google+, Wetherbug. And I see ~3% per hr average drain.
[G2 General] Gigniotron:
This is with normal daily use on a single charge.

Includes ~3 hrs screen on time, ~3hrs pandora, bluetooth, wifi, and 85% screen brightness.

Only at the last 10% did i turn on the battery saver feature wich dimmed screen all the way and turned off BT and WIFI. At 8% i turned bluetooth back on for the drive home(about 30 mins) and took this snapshot which battery was at 4%.

Not too shabby... ;)
[G2 General] wargreymon89:
If you get "bad" times you use better battery stats to check what is keeping your phone from sleeping. Installing CM or switching kernel doesn't solve your problem if you have rouge apps or settings. No BBS, no problem.
[G2 General] joshwoods:
That's another reason bad hardware may be plaguing my phone. My post a few up shows that my phone was deep sleeping 91% of the time while being used lightly.

[G2 General] G1_enthusiast:
normal...

battery thread take it with a grain of salt, because everyone usage is different, even ambient temperature play a factor in battery life. Some people buy phones just to bench battery, trying to see how long they can go before the battery dead. With that being said, I typically get 2-3 hours screen on time with 12-14 hours standby. limited wifi, mostly 4g and hspa+, screen on 55% with auto brightness, I stream bluetooth music an hour or two every day. youtube about an hour... sync turn on for fb and 2 gmail account.

I honestly think this thread is utterly useless, unless anyone can prove me wrong.

[G2 General] Iczer:
I'm not a huge power user, I text during the day, make some phone calls and browse the internet/facebook during poop breaks,etc. On my N4, by the time I got home I would usually be around the 30% range battery left. Yesterday on my G2 I had like 68% left. I don't there would be any way to justify me going to the N5 which I was still thinking about. Battery life is huge for me and so far this thing is awesome. I just hope we get KitKat somewhat soon. Hopefully that rumor of December is true?
[G2 General] yyz123:
I agree, I think any threads regarding battery life are useless unless you use the same platforms to compare.

Posts saying somebody else got 24hours of battery life vs. somebody else getting 6 is useless if they aren't honest (or maybe don't remember) their usage.

I don't typically post about battery life because I don't have much of a clue how to tweak things and everyone's usage affects things differently. This phone, IMHO, rocks though. In many ways.

I didn't take a screenshot afterwards but I ended up with 3 days and 10'ish hours around 15% and 4 hours 40'ish minutes of screen on time
