My battery life has been great since day 1, I have it on wcdma only. My friends is on auto and his battery drains fast. So I will keep mine on wcdma only.
[T-Mobile LG G2x] r4d14n7:
Am I understanding this correctly? 2G = GSM, 3G/4G = WCDMA? So when your 3G/4G signal drops, the phone won't step down to 2G. So that makes sense that your battery would last longer on Auto.
[T-Mobile LG G2x] dougstoner:
I tried the fix, and I'm still getting horrible battery life. I'm not even using it, getting a signal just fine, etc.

Cell standby 59%

Phone Idle 38%

Display 4% (Time on 26 min)

Time on is 7H 17m and it's to 38%. I've only sent a couple texts, looked at facebook maybe twice.

Maybe I'll try to add the toggle 4g/edge so I can see if that helps, but this is horrible. My vibrant was nowhere near this bad. I could easily go 24 hours+ with 3g on and medium usage.

I know the driver is a big issue, and it's not reporting correctly, so that being said, does that mean we/I can be overcharging if my phone thinks it's a certain percentage, and actually at another?
[T-Mobile LG G2x] schmit:
Tried it.. no go. You have both 4636 and network settings on auto?
[T-Mobile LG G2x] rroyter:
On the 25th, evening I followed the 4636 method outlined in OP and changed the WCDMA preferred to Auto.

On the screenshot below you can see how the battery discharge rate changed on the 26th: it's less steep.

My routine was to wake up in the morning, unplug from charger, go to work, come home, and plug it back before sleep. This included some internet browsing, texts and 4G mode all day long.

Anycut can be used to reach this menu

Just adding an FYI to this post. The app anycut ( market.android.com/details?id=com.appdroid.anycut ) can be used to access this menu.

After installing, just longpress on the home screen, pick Anycut option, choose 'Activity', then scroll down and find 'Phone info'

It will add a shortcut to this screen to your home screen.
[T-Mobile LG G2x] JsonV:
Thanks. Oddly mine was set to GSM only.
[T-Mobile LG G2x] thatmatanater:
Ahh, am i the only one that didnt get a result from doing this? =/. My battery life is still the same as usual.. if not worse..
[T-Mobile LG G2x] rroyter:
Why don't you do what I did. Run Battery Monitor Widget and monitor your battery discharge before and after. Then you will know for sure.
[T-Mobile LG G2x] wmm:
Are you using Wi-Fi Calling? Whenever Wi-Fi Calling is enabled and you have a strong connection to a hotspot, it sets the phone to be in GSM only mode, with GPRS selected (and disconnected) to minimize battery drain.
[T-Mobile LG G2x] overground:
This is true. If wifi calling is enabled no matter what you do it will always be and/or revert to GSM only. I use wifi calling at home and at work and my battery life is fantastic.

Point is, if this setting makes a difference, it needs to be monitored for:

1. Once wifi calling is disabled, does it revert to what the user set it at previously?

2. Does the menu need to be revisited to be reset after each disabling of wifi calling?
[T-Mobile LG G2x] Profondo_Rosso:
I had a G1 and a Nexus One. The G1 was abysmal (about 12 hours), the N1 was getting me about 16 hours per day, with everything on besides bluetooth. So I don't agree all android phones deliver the same amount of battery life when I just got 9 hours from my G2X today.

[T-Mobile LG G2x] blahbot90:
Well, I don't know if anyone else is having this issue, but when I switched mine to just GSM, it doesn't send out texts quickly. It literally sits there as "sending..." and does nothing. I have to hit "Edit" and then hit send again. I have no idea why this is happening but I switched back and it worked fine then.

Edit: People also told me when it showed sending on my screen, it had already sent a text, and never confirmed on my screen, and when I did the edit-send, it resent the message as expected. I have no idea why.
[T-Mobile LG G2x] JsonV:
Wow, excuse my noob-ness. I did have it enabled, as I have no reception in my house.

1. It did revert to the factory set option. I changed it to Auto, toggled wifi calling and it still read Auto.

2. It does not, when wifi calling was enabled, i successfully moved back to GSM only, and after it was disabled, it reverted to what I had set previously.
[T-Mobile LG G2x] wmm:
Yes. I have mine set (in the phone info) to "GSM and WCDMA auto", and whenever I leave my wifi zone, it automatically reverts to that setting.
[T-Mobile LG G2x] ipodkiller:
did reset last night and it worked

Ok so I can absolutly confirm that the reset worked for me. For two days in a row I got under 5 hours battery. Which for my current work situation is not acceptable. I was really not happy because I love the phone. I did a reset last night and am happy to report I got 9 hours, which is all I need/expect from my phone. The only other possibility is that I did not re enable qik. But all other apps were loaded as per my original config.

So it worked for me.
[T-Mobile LG G2x] arcanumal:
It seems to me that when I have it set to either gsm only or wcdma only, I get very low power usage (avg 5 to 20 ma) but when set to wcdma and gsm auto, I get 50 to 100 and up. I haven't had enough time to gather definitive data, but has anyone any similar experience?

Most importantly, it looks like I get the same idle power usage from wcdma as gsm when set to wcdma only.
[T-Mobile LG G2x] boldfacelies:
I sent 4 text messages and one 30 second call, the rest was sitting in class for 1 hour with no use.

Total time OFF the charger was 1 hour and 4 minutes before I checked the battery.

It was 100% when I left for school -- result: 84% battery.

12% battery loss in 1 hour. That's horrible! I barely used it!

in Status:

80% Cell Standby

11% Phone Idle

I'm waiting until I'm allowed to post images to share, but I have some pretty interesting data in my battery history. Accessible from the 4636 menu, look at the network usage. Does anyone have an entry for something labeled "0"?

Understanding that the battery meter reading may be way off, I am at 70% battery remaining after unplugging last night at 7:00pm, 100% charged. Granted, I've only made about 30 min of calls and done about 30 min of web surfing, but it's been 15 hours and the battery hasn't been touched.
[T-Mobile LG G2x] sstang2006:
about 30 minutes web surfing and T-Mobile TV app ( using wifi )

about 8 hours of sleep, alarm in the morning (3G)

another 30 minutes of web surfing (3G)

about 15 minutes phone call

[stock rom, no root, second battery charge]
[T-Mobile LG G2x] arcanumal:
What measures did you take to achieve this kind of battery life?
[T-Mobile LG G2x] sstang2006:
Brand new phone.

First charged it to 100% without interruptions. kept it charging for an extra hour after 100%.

Then turned off phone and left it charging for another hour.

Unplugged charger and power ON the phone. While it was booting up, connected charger again and left it there for another 30 minutes.

Unplugged it and started using it.
[T-Mobile LG G2x] monomojao:
Changed the setting this morning to WCDMA only and from 9AM (when i unplugged from wall at 100% charge) to 12:10PM the battery is at 24%. I must note during this time i have been playing music consistently and sent about 30 text messages, no game playing, no browsing. This cant be right...

On my previous LG Optimus T i could play music all day and at about 5 or 6 the battery would be around 30%.

I have wifi off, GPS off, Data On, and very very low display, to the point where i can barely see (the lowest setting)

Am i doing something wrong here?
[T-Mobile LG G2x] spencersir2:
Well you changed it so that it is only using the 3G/4G network which also means that if you aren't in range of that specific network(3G/4G) it wont just kick down to edge/2G like normal it will sit there and scan until it finds the 3G/4G network again.(Plus to top it of the cell standby is already a huge power drain for some reason with the G2x)

O and i just noticed that you said data on... This is murder, i mean absolute murder for your battery(especially if you have auto-sync on)

What you should do is click the link in my sig and go check it out at least and it will help you with your situation!
[T-Mobile LG G2x] monomojao:
The only problem i have with your tips is the rooting process.. i really dont want to screw up things and i dont trust my skills to that level yet... :(
[T-Mobile LG G2x] spencersir2:
Well your in luck. Thanks to the wonderful Android Community, and to XDA for bringing us all together, there is an easy way to do this. It is called SuperOneClick and it is literally one click(After you open the program). This is a huge leap from when i first rooted my G1 and had to use ADB and typing and moving files etc etc... but with this you simply download the program, make sure you have the LG driver to connect your phone to your computer, plug your phone in and open SuperOneClick, and than click root. And TAH DUH you now have root access. To top it all off if you ever need to send the phone back to LG or T-mobile for any reason simply re-plug your phone in and click unroot. Trust me you haven't experienced the true android "Experience" until you root your phone.(Especially when we can finally overclock these bad boys! Dual-Core MONSTER NOM NOM!!)

Wow thank you so much for your time... I will definitly look into this!!!!

I havent read the link you posted yet, but if i root does my UI change from the way it looks now? or it just means i have access to everything on my phone? Cus i have read about roms like cynogen that i could load, etc etc that rom thingy is what confuses me
[T-Mobile LG G2x] Amd4life:
I get "connection problem or invalid MMI code"

what does that mean?
[T-Mobile LG G2x] spencersir2:
Rooting your phone simply gives you access to certain Administrator Rights in the phone(like being able to get rid of system apps), The UI only changes if you flash a new rom onto your phone(It is basically like installing an update), but outside of root I would definitely not flash anything until you do more research. Because you will need to learn about kernals, Recoveries, the different types of roms, etc... But in my honest opinion everything I have on my thread is simple and safe. Although, if you decide you want to play around inside your phone more(Which everyone eventually does after they root) make sure you have a Recovery and Backups(Which you will learn about by simply reading the forums).

P.S. If you can't tell by my sig I am Definitely i Cyanogen fan and in my opinion his (final version) roms are very efficient, have powerful and battery sipping kernals, look great, and have almost every extra that you would need. So just saying Cyanogen FTW.
[T-Mobile LG G2x] spencersir2:
Well how did you get there? What did you do?

Was it an app?

Walk us through step by step so someone on the forums could help you out!
[T-Mobile LG G2x] monomojao:
why havent your loaded a rom on your current G2X?

And if i root my phone does that mean i wont be getting the gingerbread update when its released by the magenta?
[T-Mobile LG G2x] spencersir2:
I haven't cause one I am lazy two cyanogen hasn't released one three want to see what true gingerbread is like and four the recovery programs out right now for G2x haven't combed all the bugs out yet. And you might have to go back to nonroot to get the update from magenta you just never know with updates.
[T-Mobile LG G2x] Mikeglongo:
I rooted my phone, but when I did ROM manager and what-not, I think I screwed up the back-up/restoring because when it rebooted, it didn't load.

I got an exchange, but now I'm afraid to do the ROM manager thing again. I'm new and tried following the instructions, but don't know what went wrong.

I want to try and do it though, I would love to freeze the bloatware, but I want to make a recovery first.

Stuck on GSM only

Is anyone else having this problem? When I change it to auto, it just reverts back to gsm only after I check it again? Anyone know why?
[T-Mobile LG G2x] Rayvenhawk:
My G2x

Ok I like most here in this thread jumped on the bandwagon and bought the G2x (simply for the front facing camera), I jumped from the G2.

Anyhow my first G2x had horrid battery life (got maybe 8hrs if I was lucky, drained at about ~11% an hour), had it reboot on me twice while in standby mode, was playing a youtube video and the screen shut off, video still playing (heard audio), the buttons lit up and I had to put it in standby in order to get the video back on. Also had an issue with recharging I had to pull the battery to get it to charge up again.

So I replaced it with a new one, so far the battery is doing good (I got about 15hrs with moderate random use before it went dead), I did a full drain (turned it back on until it wouldn't anymore), I found that was the cause of the failing to charge from my first phone. As I sit here my phone rebooted twice and then shutdown.

Long story short I followed the steps here from page 1 and went to batter info and found that mine is showing Battery Health: Overheat, temp is 43.9 degrees Celsius or 111.02 degrees Fahrenheit.

I wonder if that is the cause of the random reboots, an overheating battery. Of course I'm sure someone here has already mentioned this but I'm not in the mood to look through the 100's of pages regarding the battery & rebooting right now to verify that.
[T-Mobile LG G2x] wmm:
Are you using Wi-Fi Calling? If so, that's the reason: whenever you have good signal strength from a wifi access point, Wi-Fi Calling puts the phone into GSM-only mode with GPRS service and GPRS disconnected to reduce battery usage. When you turn off Wi-Fi Calling or get out of strong signal range from the access point, the setting automatically returns to what you had selected.

If you're not using Wi-Fi Calling, I don't have any idea what might be causing this.
[T-Mobile LG G2x] monomojao:
this is what i was trying to avoid.. :( one click root seems to have its flaws too
[T-Mobile LG G2x] spencersir2:
Well one click root really doesn't it is just their is no support for recovery or roms because the G2x just came out but I would definitely root just for the battery life alone.
[T-Mobile LG G2x] spencersir2:
It could be because it would make sense. The system would force a reboot to make sure that the battery over heating wouldn't fry the circuit.
[T-Mobile LG G2x] Mikeglongo:
Spencer, after a root, can I use freeze to freeze the appps? Or do I have to create a back-up first?

Thanks for this info.

Got the phone last night. Booted, setup wizard, factory reset, then did method after titanium finished restoring. Sitting at 36% battery, unplugged for 5hr 44 min, with 1hr 32min of display on time. Seems to be on par with my Vibrant at the very least. Granted this is the first full cycle so hopefully itll get better.
[T-Mobile LG G2x] bananaslug:
I don't think draining the battery completely and charging your phone until 100% while off can be emphasized enough.

Yesterday my phone lasted about 8 hours of moderate use and hit the 30% battery mark, I was kind of pissed because my Nexus one lasted longer so i decided to drain it completely while playing games and then charge it to full battery.

Now its been on for over 12 hours and is sitting at 69% battery with about an hour of screen on, some texts and a 30 min. call.

I haven't taken any other steps to conserve battery life other than the gms/cdma set to auto in the secret menu, but that was days ago and it didn't seem to do much.

[T-Mobile LG G2x] lilaliend:
I haven't read thru this whole thread, just the first couple pages. Don't know if it's been resolved, or if I'll be repeating stuff. Just chiming in w/ my own results though.

The first weekend I got the phone it died on my 3 nights in a row while going out. After leaving the house it would die about 4-5 hours later. Each time I only really texted people trying to meet, work out plans, etc. No Bueno.

So far this weekend my phone has stayed on from Friday afternoon to now, Sunday morning. I only plugged it in briefly yesterday morning and charged it from 48%-56%. I've made several phones calls, sent a few dozen texts, and been online to look things up 4/5 times.

After rooting I froze a few bloatware apps: Car Home, TeleNav, WiFi-Calling. I set my network settings to WCDMA only, and I only turn WiFi on when I'm home. A couple times I've checked running services and stopped facebook and tweetdeck after using them so they wouldn't keep checking for updates.

After those few things my battery has been great. Haven't factory reset either. I installed JuiceDefender last week, used it for a day or so, been disabled since.

Going to give iit a try.. I doubt it can hurt anything so might as well give it a try.
[T-Mobile LG G2x] Spoo76:
Wow I am really surprised how much and how quickly battery life has improved, you weren't kidding when you said immediately noticeable.

Mine was also set correctly in phone menu but not in the Test menu.

Ive only had my G2X since Saturday afternoon. and so far even after a factory reformat and letting the battery drain to calibrate the driver it wasn't great.

I havent pushed it hard but in the last few hours but I have streamed music from sound cloud on 4g and wifi, calls and a few other typical things and it has barely made a dent!

its now been another 2 hours off the charger and its still at 90% Im going to play a few games and Ill see how it is tonight.

I may even not charge tonight and see where it is in the AM. something Ive NEVER been able to do with my N1 that seems to live on a charger
[T-Mobile LG G2x] Spoo76:

[T-Mobile LG G2x] alodar1:
You know, this is not specific to this phone. The 'fixes' related here, switching settings etc, are available on many, if not all smartphones. The primary drain in these cases are most likely band switching, or the lack of band switching. Take any smartphone into a dead area and watch the battery drain as it continually tries to lock on a band. These switch changes simply lock to a band.

The Idle reading 'could' indicate, I'm locked to a band that is not available. My son lives south of Olympia WA with bad 3g/4g reception. If he leaves this setting on Auto, the battery drains in a few quick hrs. If he locks on Edge, his battery lasts 3 days.

If you're in a high 4g area, your battery usage can simply be a 4g power thing. But because 4g is not wide spread, yet, locking on the high bands will cause the phone to poll for the high band more often...increasing the drain.

We all want to say we have a 4g phone. But having a 4g phone in areas without great 4g coverage = High battery drain unless you manage the 4g polling.

Some place on XDA is a real good document on this. The only issue with this thread is it combines multiple reasons into a single solution without defining that Good 4g Coverage on a 4G phone will still use more battery than good 3G coverage on a 3G phone. Changing these setting won't impact this...unless you turn off the 4g settings and force the phone to poll only on 3g or below. That uses less power by default.

Lock to a high band in a Good 4g area = same battery impact

Lock to a High Band in a marginal 4G area = higher battery drain

Lock to a 3g band in a good 4g area = better battery impact

Lock to a 3g band in a marginal 4g area = better battery impact

Lock to a lower band in a good 4g/3g area = even better battery impact

Lock to a lower band in a marginal 4g/3g area = even better battery impact

Lock to any band in any area with questionable coverage = bad battery result...turn the phone off.

Test this on any smartphone...Apple, Windows Mobile or Android....its the same.

No option with MIUI 1.99?

So I'm wondering:

1) With MIUI 1.99 (thanks Whitehawkx!), in the hidden menu there's no "GSM/WCDMA auto" option, just a "GSM/CDMA auto (PRL)" option. Anyone know if that would set the same radio state, or make sense to the G2x?

2) Given the age of this tip/thread at this point, is the consensus that this actually does boost life on a the majority of phones, or is this just random coincidence?

3) In the same hidden menu, even though my phone was only awake for ~1h of the last 10 hour battery cycle (not great, not abysmal), under the Battery History section, my phone showed 5+h "running" when the screen time was less than a fifth of that... this could clearly explain where the juice is going, but any ideas how I track down the process that's going bonkers? When I view the apps/services running, everything seems pretty harmless (SetCPU is running in the background, but that should be low power drain).

Thoughts? Danke.

I can attest that there is a difference between the Settings/Wireless Networks and doing the *#*#4636#*#* menu. Under the user interface settings/Wireless Networks menu, it was set to AUTO. I was wondering why when I traveled, it would never switch to the AT&T towers for roaming. My wife has an iPhone (unlocked on TMO) and it would switch towers just fine. When I did the *#*#4636#*#* menu it was set to WCDMA only. So that is why it wasn't roaming. BTW, I'm using Weapon 2.8 OS.
[T-Mobile LG G2x] pmorrsn:
I was getting about 1% battery use/ hr overnight with my G2X, then I tried a new ROM, had problems and reset back to my Froyo and my battery use is now ~4% / hr overnight, a several fold increase in drainage. I have done my best to return all original settings, most were stored anyway. Clearly its not a usage issue. My phone brand new, had a similar drain rate. I fixed it by keeping on wifi, as I am almost always in a high wifi area. That solution no longer helps.

Also, adding, that I put phone into Airplane mode for an hour and noticed the 4% decline in battery. I am now getting ~16 hrs of life, rather than the 30+ hrs I was getting, apples to apples.
