Anyone else having this ISSUE? My last phones all had like 4-6% standby time on the battery. But this g2x has been 64-83%. If this can get fixed I think my battery will be much much better!
What can be causing this?
when you say 64-83% how many hours has it been in standby? What else is using the battery? I know the G2X in my office has like 70% standby but that's standby from 14 hours and it's still at 92% battery life. (work phone so pretty much just sitting in the office until we need it)
Standby usually drains faster if you're in an area with no cell signal from what I've noticed.

This is very important to note. As the signal gets lower, your antenna has to increase power to maintain a connection with the tower. The lower your signal, the more battery required to keep a connection
My cell standby has been alot more then my display and I don't have it in standby. What is odd. My network connection says utms yet I have 4g showing and speedtest is 4-7mb dl. I can unplug my phone leave it on for an hour loose about 15-20% battery with it like at 70%+ cell standby. It's odd...
Maybe it's the 4g cell struggling to connect?

Do you have a lot of Widgets pulling data?

I have the same widgets on the G2x that I have on my Nexus S. I have pure calendar and pure calendar agenda both set to update when the calendar updates. I am still leaning towards more with the 4G struggeling or something.
I've always thought umts was pure 3G while hspa was an update to that which in turn you could get the hspa+. However my connection always says umts, yet I do get way above 3mb dl on the speedtest. It always gets between 4-7mb dl.
The battery life on this android reminds me of when I had the Eris, just blah!!

I have the EXACT same issue with cell standby. I think it's the 4g connection as mine is constantly switching between 4g and 2g (never 3G)
I can't remember can you click on the "cell standby" tab in 2.2 to get additional information? It will usually say something like xx% time without signal.
yes you can click on it but that option is not showing. I was thinking just like I could my Eris was place into airplane mode take it out and it would correct the cell standby issue. But the xx% without signal is not showing. Well at least on mine it doesn't.
I don't think it ever says 3G. Mine goes from 4G to 2g. I just traveled to Indianapolis and pulled 6mb down but at home we don't have 4g yet even though it says 4g. My download at home was the same as my nexus one = 700k
So while I see it drop to 2g... I think they replaced the 3G icon with a straight 4G icon.
Plus I thought utms was edge?

Same here with the cell standby... Battery life isn't that terrible for me though (six hours down to 75 percent). Still this seems to be a big problem. Can we somehow force it to just use 3G for the time being?
Make air plane mode your best friend when your not using it. It could be widgets your using

I was having the same issue, and battery life was terrible.
Performing a full factory reset as well as completely draining the battery several times solved the issue for me.
Before the factory reset Battery Monitor was reporting heavy battery use even while idle, after the reset it only uses 2-5mA while idle compared to over 150mA before.
Today I went from 5:45 AM to 4:30 PM and am only down to 70% charge left.
same exact issue here. My usage habits have not change from my mytouch 4g which only showed a few percent of cell standy and phone idle. I dont get it, but i think that is what is killing my battery.

Not the same. We want an option for JUST 3g as the problem (with the cell standby) seems to be a weak 4g signal...

I'm glad it worked for you but I am a little confused as to how could this fix this problem?
I'm on the EagleBlood Rom and currently in Singapore. Becsause I'm not using T-Mobiles expensive service and WLAN is here everywhere I have used the phone with WLAN + GPS only (Airplane mode + manual turned on WLAN + GPS). I used Locus Pro extensivly to navigate through the city and record my track. Battery after first day 8:00AM til 9:00PM was 79%. Second day is 55%.
Therefore the Cell Standby is really the issue here I would asume. But hack what do I have a cell phone for if I can't turn on the radio???
Battery really sucks otherwise. When I go to work at 07:30am and come home at 4:30PM I can put the phone on the charger, even though I barly used it.
I'm in the states, this phone lasts from about 7:30 AM until 8:00 PM with no problem, regular use, 4G all day. I disabled the Wifi which helped a lot.
Wifi uses less battery due to not having to poll the network to renew the connection. Wifi calling uses even less battery because now you have no connection to the network and it can keep a static connection to the wifi network. No need to renew that connection so it just sits there and does nothing.
I've tested and confirmed this on more than one phone.
And of course the radio is using battery. It's second only to the display in battery use. Like you said, what good is a cell phone without having the radio enabled?

This all true. Display and 3G/4G radio are the killers.
Unless you have wifi on and aren't connected to a network. Then your phone is polling for wifi connections in addition to 4G
Yay! Yet another battery thread that I get to comment on!
i use wifi/wifi-calling over 95% of the time and my battery rocks! The moment I turn it off... bam.... I get crappy life on a batter. the difference is from around 35hr and drops to around 20. Then if i had moderate to heavy use on it, I'm sure I'd be getting the 8hrs everyone is complaining about.

I'm going to Hong Kong this Sunday, then will be in Singapore by the end of next Wednesday. I'm thinking to buy a local sim and use 2g only with manual WLAN, GPS off.
Agreed. I'm running CM7 #9. Took the phone off the charger at 8am. Checked my push exchange, twitter, and facebook updates. Went into work where we have no service. I have WiFi turned on for data.
I still have the cellular radio on, btw. At 3pm I have 88%.
CM7 has a WiFi bug which the WiFi won't stay on (goes to sleep with the screen off). But still pretty good.
it has been proved that 4g kills battery faster then 3g and 2g. http://blog.lifehacker.com/5741627/why-you-might-want-to-wait-for-a-4g-phone until there is a way for 4g radios to manage data more efficiently 4g is gonna kill you battery.
I'm using Eagle Blood 1.03 and my battery life is awesome right now. I think at this point, I could do a couple days before running out. I am just speculating right now, but I will try to leave off the charger tonight to see what I can get out of it.

Hong Kong Airport has free WLAN. Singapore has free wirless LAN called [email protected] through the whole downtown area. But there is a catch you have to have a Singapore Mobile number to register. They will send you the UserID and Password via text message. Lucky me I have a friend here sharing his user ID with me ... Therefore no need for the Radio to be turned on at all. And like I said the battery now last forever...

Ok let me see if i understand (not trying to be a **** here), if all of the phone functions are turned off, what were you doing?, playing games?, watching videos?, i don't know, because to me it sounds like you phone was idle.
One more example that 4g kills battery is the thunderbolt, if you think that the G2x kills battery you should use that phone and comeback to the G2x, even HTC is selling bigger batteries for thunderbolt because customers are *****ing about the battery life.
You should try and use 2g only and see if this helps you battery life a little, i guess im just lucky, i have no screen bleed, no reboots and battery life for me is awesome, whit and without 4g.

Dude all the functions are turned on except the radio. I use the phone in airplane mode with WLAN + GPS enabled. I use GPS apps to track my way to Singapore. In downtown they have free WLAN everywhere. Phone last for 2 days this way, but makes no sence of course having a phone without a radio...
Oh and I use Sipdroid with Sipgate to receive and do free phone calls

Just making sure here, but you know that T-Mobile's 4G is still using the same existing 3G connections, thus not requiring it to run on a different band, right? HSPA/HSPA+ connections share the same bands, and thus the "4G" connection is running through the same radio without affecting battery life. WiMAX and LTE operate differently and both run seperate from the EVDO that Verizon and Sprint use for their 3G.
That being said, a radio, regardless, will always drain the battery faster than anything, which is why Wifi Calling is so effective in keeping high battery life.
The other HSPA+ enabled phones on T-Mobile are getting fantastic battery life, as long as you aren't constantly using the displays.
I am leaning to believe that's a major reason why everyone's phones are dying so fast. They've got a new toy so they're always playing with it and killing it quickly. I've done that with every new phone I've gotten. My G1, the Cliq, the myTouch Slide, and now this. Give it a few days and when you're not turning the screen on every five seconds to just flick around the menus, and you'll see your life improve.
Yesterday, for example, I ran my phone off of charge from 11 AM EST until 6 AM EST (6 AM, Monday Morning). This was with moderate use.
Its not just that we're playing with our new toys. This phone most definitely drains battery like its going out of style. I had to drive 90 minutes to the client I was coming to work with today. I unplugged my phone when I left my hotel room (and it was at 100%) and when I got to the office, 2hours and 15 minutes later, having never turned my phone on since I was driving the whole time, my phone was at 82%. That's really bad for a phone idling. I think there's a radio bug or its polling too often because if I let JuiceDefender work, then in the same period of time this evening I was at 94% battery. That's a big difference.

I know HK airport has free WLAN, but places like starbucks/Mcd only offer 30 mins- 2 hours of free WLAN a day.I will be in HK for a month(after I got back from Singapore), so I might need to purchase a pre-paid internet plan..I will be in Singapore for a week, so hopefully they will have unlimited free WLAN there...
IT'S NOT 4G THAT'S KILLING BATTERY. As was stated above it uses the existing 3G network for faster data speeds. Phones like the Thunderbolt and EVO (and anything else that connects to WIMAX or LTE) need a completely separate radio (and thus controller) to connect to 4G.
HSPA+ is just really fast 3G so the existing SOC's that have support on-die for T-Mobile 3G frequencies just have to have a slightly updated version of the hardware (to support either class 10 or class 14 HSPA+).
This would be a perfect example as to why T-Mobile and AT&T shouldn't be able to market HSPA+ as 4G. It confuses people and makes them think that battery life will suck because of it like it does on Sprint and Verizon. When SOC's come out that have on die support for LTE and WIMAX (I think I heard 2012) then battery life for those phones won't suck anymore.

The antena-radio, is using more battery, just because is handling data at a higher rate.
Just like I said before, until there is a way or update to the radio to handle data more efficiently, 4g radio is gonna keep draining battery.
And yes hspa+ and wimax are similar yet incompatible technologies, but the way they handle data take a big chunk out of you battery.
And is a fact that radio is draining most of the battery, and until we get a radio update, battery is gonna drain fast.

I noticed yesterday that for the first time at work that my phone doesn't show the 2G icon (I have the use only 2G networks tab checked), just the wifi signal, and that the battery lasts waaaaay longer. Haven't noticed if it does that yet with the wifi at home (hasn't before either place, it would show both icons). But I'm going to check this evening. Not sure what changed, but I'm glad, now getting 10-12 hours under moderate use instead of 6+. I'm aware this may be old news but I didn't do anything to change it. fyi
That is great that your battery improved. Do you remember making any changes to Apps or sync settings?
The phone lasts much longer when using Wifi for the data connection. I can make it through a full workday connected to wifi, well usually anyways, but on the network I have to charge at least once, often more.
If your phone was showing 2G and wifi, that means it was connected to both but only using 2G. Its a bug and you should try disconnecting and reconnecting if it happens again. Or restart the phone.

After reading this post I went ahead and selected 2G network only and turned on my Wifi. My battery lasted MUCH longer.
2G should last much longer than 4G.
Try CM7 #38. 10am-midnight @ 67% left.
I think they fixed the battery drivers finally.

ok so here's the deal.. my phone has been off the charger for about 4 hours and im already down to 40% left. I live in a 4g area but it is spotty in many areas, including my workplace. I have gps (for weather updates and nav, when i need it) and wifi on at all times. i am running the EP4P modems on GummyCharged Froyo ROM 2.0. I have the screen brightness turned all the way down. No overclocking.

I have tried several different methods to calibrate the battery but it doesnt seem to help. When i'm at home and using wifi the battery life is pretty good. so is it my modem? the ROM? my kernel? Can anyone help me get the most out of my phone? I've tried various modems but have stuck with GC since I loaded it back in sept.
If you are in a spotty area, that can happen. Searching for signal and 4G/3G switching can drain the battery very fast. I would try putting the phone in cdma mode while you are at work or any other spotty area.
Turn off wifi and gps if you are not currently using them, wifi scans for networks regularly and you may have apps/widgets that are using the gps/ network location services while you are idle
also, my battery stats say that display is using up 45% (as of now) of my battery life with 23 mins of usage time. I have the wifi turned on for my convenience, but it doesn't scan for networks as i've turned that function off. I will try the cdma switch, but I have also tried that before and I don't think it makes too much of a difference.

The battery usage metrics aren't useful until you've been up for several hours. And having the screen using a high percentage is ideal -- it means that the rest of the system is throttling like it is supposed to.
How long have you been on GummyCharged? A few weeks into having that on my phone happily, battery life took a nose dive similar to what you are experiencing. I flashed back to stock and battery life is much better. Waiting for official GB before trying another ROM.

i see your point but im now at 5 hours uptime with 23% battery left.. light/medium usage. display still says 46% battery use with 25 mins of usage time. that seems like incredibly too much battery drainage.
also, when i put the phone into cdma mode do i select the home or automatic option, and what is the difference?

i flashed GC onto my phone in mid september. since then i've tried calibrating the battery several times. a totally futile exercise it seems. What setup are you running now? 2.2.1 with EE4 modem? Rooted?
The only thing that has solved my battery problems is juice defender. Sitting idle for eight plus hours at night I only drop about 3-5%. Of choose it still drains just as quickly while using the phone but it will help if you're in a spotty area because data is turned off if your screen is off.

I have similar issues. After rooting and flashing Humble on my phone, my battery life sucked, much much worse than stock.
I then put the standard 2.3.6 on it and it still sucks. Full 4G all day, barely use it.
It's sat on my desk at work all day today. Sent a few texts. I've installed betterybatterystats and nothing is taking up a large portion of partial wakelocks.
Really don't understand how people are getting such good numbers...
I find that by far and away the best way to increase battery life is to lock my phone in 3G unless I am downloading something & want the 4G speed.
I have a home screen widget that turns 4G on/off & only turn on 4G occasionally. I do not leave WiFi on although I leave GPS on at all times & find that uses almost no battery life whatever.

I thought my battery was bad then i looked at that graph. I don't even get it... The screen is mostly off and the signal is green most of the time.
It may be some rogue app on your phone. Backup your apps and do a factory reset. If your battery life significantly improves, restore your apps one by one and find the culprit.

Just stock EE4, unrooted, will do OTA as soon as I get the notification. Battery life is not that good, I can get 14 or so hours of use leaving it on 3G most of the time, but on Gummy I would get 50+% drain just having it sit overnight. Now leaving it sit overnight doesn't kill it.

you prob shouldnt be using that ROM..its kinda outdated...just flash the new ALL IN ONE ODIN of EP4D...my battery life is pretty sick...i left it unplugged all night and saw a tiny drop..my phone was connected via wifi tho..if my phone is in 4g the battery loses pretty quickly or if my screen is on ultra bright..
I'm running the stock, rooted, manually-debloated EP4P and I've been getting downright stellar battery life.
My kids watched an hour of Netflix this morning while getting ready, and now (almost 10 hours later), I'm still at 63%.
But! (and here's the kicker) - I leave WiFi on all the time (I'm contemplating buying Woofi to save even more battery when I'm not at home or work) and have my WiFi sleep policy set to "Never".
This is (one of) the key(s). It doesn't matter how strong your 3G or 4G signal is, WiFi will always save you battery. 3G is less battery intensive per-time, but much more battery intensive per-byte. 4G is less battery intensive per-byte, but much more battery intensive per-time. WiFi is much more battery intensive per-time, but wildly less battery intensive per-byte.
In other words, for the same download, you'll use the least battery on WiFi (even with a slower than LTE connection), 4g in the middle, and 3G the most.

But! (and here's the kicker) - I leave WiFi on all the time (I'm contemplating buying Woofi to save even more battery when I'm not at home or work) and have my WiFi sleep policy set to "Never".
This is (one of) the key(s). It doesn't matter how strong your 3G or 4G signal is, WiFi will always save you battery. 3G is less battery intensive per-time, but much more battery intensive per-byte. 4G is less battery intensive per-byte, but much more battery intensive per-time. WiFi is much more battery intensive per-time, but wildly less battery intensive per-byte.
In other words, for the same download, you'll use the least battery on WiFi (even with a slower than LTE connection), 4g in the middle, and 3G the most.

is there an odin file for what you have or did you do the manually debloating after rooting?
Will the phone have a longer battery life if the cell modem is set to 3g vs lte?

Yes, in my experience with the S4 it's a pretty big difference UNLESS you get a very strong LTE signal. I'm on tmobile and now have the N5 and use the 3G setting which is HSPA/+ Plenty fast for me for what I do. When I want some extra speed I'll kick on the LTE
Does anyone have a more detailed answer for this? I just got this phone yesterday so I haven't been able to find out myself yet, just with 5hour battery life from 100% to 4% on what will only be half of its normal day I'm looking for anything to help right now till I get a battery case. This phone is one of only two to have a LTE radio that is supposed to use 30% less power than usual so I'm wondering if that makes it as efficient if not more than 3G for idle in your pocket to light stuff like FlipBoard.
it would depend on the quality of the data connection. im in brooklyn nyc, and use lte on my nexus 5 exclusively, used to use it on my nexus 4 as well. with 3g(hspa+), on both my n5 and n4, i average about 4-4.5 hours screen on time. when using lte, i average about 5-6 hours screen on time on both my nexus 5 and 4. after noticing this difference, i use exclusively lte on both my devices, as i average an hour more screen on time when using exclusively lte.

Serious battery drain can have many reasons. One is having LTE on, syncing on(if you just booted it up, and input your Google account and let all your apps sync and download, its gonna drain your battery fast the first time), having locations on and wifi enabled. If you are in an area with poor reception, your phone will drain more trying to find connection.

Thanks for the information. That's what I was wondering but I couldn't find anyone that had already tested this with these new radios. If I get the time this weekend maybe I'll do my own test in detail to compare LTE to 3G. Am thinking of using a TV episode on Netflix and see which makes the battery drop faster over the 30 or so minutes.
Slightly off topic, does anyone's WiFi show as always on in the battery monitor even if its been off? Still trying to figure out my battery drain issue, if it even is an issue with just me, I bought this phone knowing it had a small battery.

go to the main phone settings, wifi, 3 dots on the bottom right, advanced, then disable scanning always available..
ill be interested in seeing your results

Seems that's a whole other debate on weather leaving that on or turning it off helps battery life. Apparently if you turn it off then apps that want your location will turn the GPS on and waste battery (looking at you Facebook...), but if you leave it on the phone just tells the app your location from WiFi networks around you.
One thing I didn't think about is I had added my work WiFi yesterday but it wouldn't connect to it, wouldn't tell me why but I'm assuming it's because of bad signal as I'm a valet outside and the WiFi is from a bar across the street so I forgot about it but WiFi was left on with that network saved, my Nexus 7 can connect to it on most days and any laptop has no issues but with this being a phone I guess it doesn't have a big enough antenna. So I'm wondering if now that I deleted that WiFi network, and I always have my phone set to not notify me of public networks, if my battery won't die so fast today.
And now I'm just rambling but I just looked at my screenshot I took yesterday of battery use before plugging in at 4% and WiFi isn't even being shown on top six things that used the battery, lowest one being shown is a Chrome process using 3%.
EDIT: Well off to work now with my phone 100% charged, will have screen 100% (am outside in the sun), BT off, WiFi on (disconnected, no saved networks nearby, open network notifications off, always on during sleep, scanning always available, avoid poor connections, and WiFi optimization), LTE on/connected, NFC off. So lets see how things go. It will have tons of screen on time as all I do at work is read through FlipBoard, then if I run out of things on there I move to FB. Lets see how this goes...

Nexus 5 has it and its doing its job saving battery
Sorry for digging up such an old thread, but with LTE my Nexus 6P, it switches between HSPA and 3G. When turned to 3G, nothing changes. Would that mean I would save battery?
