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.

If you saying only 4G I cannot share the expirience with you. I even turned of data completly, while I was still in the US and still got bad battery life with ONLY the radio turned on (WLAN + Data + GPS turned off)

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 know 4g is a battery hog, however how would you rate the following with regards to which uses more battery from most to least:
3g, 4g, weak wi-fi, medium strength wi-fi?
I'm guessing
1. 4g
2. weak wi-fi
3. 3g
4. medium wi-fi
I ask because right now I'm waiting on a new usb port for my nexus and in the meantime I am fortunate to have a spare charger, however it takes 3 hours to fully charge so I'm keeping data turned off unless I need it because my samsung galaxy nexus only lasts 2.5 hours w/ heavy use and auto brightness turned on...rooted w/ Sourcery and Lean 43.
Thanks in advance

my personal opinion is that wifi uses the least battery, regardless of 4g or 3g.
4G uses more battery than 3G than wifi
4G>3G>wifi>2G:laugh: wifi is best than 3g and 4g
4G drain more
Thanks.
So regardless of how strong the wifi signal is, using it will eat up less battery than 3g?even when it takes 30 seconds for a Web page to load? I would have thought it would be better to use 3 in cases like that.

I agree
4g just drains your battery than the other
Thanks for the replies

just background data tasks, mobile gaming, streaming
1. 4G
2. 3G
3. Weak Wifi
Big Download
1. 3G
2. 4G
3. Weak wifi
Reversed the differential on big download because the difference in 4G speed is very significant and you may very well waste battery on 3G by engaging in extended radio transmissions to and from the tower that 4G would have ended long ago. 3G will use much less at continuous tasks at a fixed/slightly variable(but well within 3G's capability) such as gaming and streaming. Both should be fairly equal at idle aka not tranmitting/receiving data, provided your phone is indeed going to sleep and not transmitting data every 2 seconds. But if you got apps waking it up every n minutes, expect 4G battery drain to go up. The moral, leach wifi where you can and make sure your phone isn't talking about you over the air all day.
