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.

Hey guys just wanted to know how does different network/radio affect the battery life? I am on rogers.. if I am on LTE I usually only get about 10hour or less on 3G I can go for more then 2 days...
There is no easy answer to this question. Battery life is often a function of network reception, which varies drastically by location. If you are seeing such a huge difference from being on LTE, its possible you are in a fringe LTE reception zone and the phone is constantly scanning and trying to connect to LTE and draining the battery. Flashing a different radio may help, but its not necessarily a silver bullet.
Battery life always varies quite a bit from person to person, even regardless of LTE. LTE adds another level of complication. I'm on LTE all day, and I can easily get 24 hours or more before needing to charge. I think some on here have mentioned getting 2 days on LTE.
I'm on LTE 24/7 and my phone makes it through days no prob. I do charge each night while sleeping, but that's to be expected IMo.

I've had this thought for a while, but haven't found any practical way of implementing it, perhaps having it out to the broader public may help.
LTE or 4G, as we all know, is fast and great, but it also demands more on our batter than good old 3G.
These are some of the scenarios in which I would love an app, or OS be able to make smarter decisions about the network.
1. When connected to WiFi - When connected to WiFi, our battery life improves when compared to 3G or 4G, but I find sometimes that even though I'm connected to WiFi, my cell network is still connected to 4G (at home, my 3G signal is full bars, but 4G is 3/5), thus, wasting a bit of battery.
2. When phone is in low data use state, or lengthy sleep - Often, when I'm in the office for example, my phone sits there in standby for hours at a time (my emails come onto PC, plus I wear a moto360 so i check notifications there). In these modes, LTE is of little use for me, yet it can often spend hours in LTE standby.
I've looked into IFTTT, and messed with other software apps, but I always end up with the same conclusion, that is, this would have to be manually done...
does anyone know a way?
If you have a root you can do with with xposed and gavitybox (smart radio). I think some other modules can do it as well.

Let me guess, not on Telstra. Battery life on mine with Telstra is superb, even with 1-2 bar signal. I guess that would be because it is a stable 1-2 bar, unlike the issues I had previously with Optus, were my phone would drop signal very often in built up areas

Yes, not on Telstra, but that is besides the point here. This is not an AU specific thing. I travel internationally a lot for work, and this would be the same when I'm overseas. In fact, not complaining about battery life at all, just think that the way the phone manages its connections could be improved - this is not a problem on the Sony, but on most phones.

Hi all,*
I am currently in Japan (originally from India, just here for a business trip for two weeks), using OnePlus 2. I bought a new data sim card and thought I would use it along with my Indian sim card. Two problems popped up:
1. When the Japan card's data is active, the Indian sim losses signal completely. Whatever I try, only one sim gets signal... Not both at the same time.*
2. "Cell standby" started showing up in the battery draining apps. Today morning, after a full charge, if lasted for about only 4 hrs! Now I checked the battery stats, cell standby is taking about 22% drain! I have even removed my Indian sim in the morning itself but this still *persists!*
Please help guys! I am here in Japan for another 10 days and this is torture! I don't mind the other sim not working for now (though I wouldn't mind a solution either), but I need the cell standby to disappear!*
Thanks in advance!!*

i cant help with the sim issue, but usually any excessive battery drain from anything cell related is due to poor or weak signal, doesnt necessarily have to be weak to be poor. could also be some sort of poor communication management from the carrier. either way, there is no general fix that im aware of other than choosing a more popular carrier and/or one that has better coverage where you are.
My S8 plus had terrible battery life compared to the reviews . I get an average of 3-5 hours of SOT
i opened the stock android battery monitor and couldn't see what was eating up My battery so i downloaded the gsam monitor and found out that the phone radio was totaling a 60-70% of my consumption even exceeding my screen power consumption.
But i had excellent coverage(always full bars and -70 to -60 dbms)why would my phone radio consumption be that high ??
And my phone could last up to 11 hours of screen on time with continuous wifi websurfing with no mobile data usage so i know it isnt defective
Well i decided to do some research and testing.
In my country the cellphone network companies signed a national roaming agreement in an attempt to allow better coverage , which basically means that i can connect to any tower in my country even if its not the one that belongs to my provider. Which makes my phone always looking for the tower that has a stronger signal and switching to it.
I then decided to put that theory to the test and downloaded an app that lets me see the towers i am connected to
Check out the madness

3 towers in an area of less than 300 meters raduis and my phone keeps switching up between them .
So no matter what i do i will get the battery life of a roaming device ?

That the same issue i am facing here. I'm using lycamobile during my visit in germany and i noticed a heavy battery drain during the standby. Usually i disconnect my phone from the charger before i sleep so i always loose arround 6 to 7% also i can confirm that roaming is actually consumes lots of juice specially mobile data. While in wifi network the battery life is great.
Try to use a local sim card like Vodafone or etesalat and compare it to the one you are using. Cheers

Aha i got your point now. Well i am not sure how you are going to solve this problem as you can't do nothing about it. Have you experienced the same issues with your previous android phones!
You shouldn't have any problems with battery as your network provider assigns automatically to the nearest tower to insure the best network reception.

The constant connection and disconnection from towers does drain battery
My previous smartphones always had a battery life that is sub par with reviews
So today i activated tge 4g service on my sim card as the national roaming doesnt work on 4g . And to have 4g u have to be connected to your providers tower only ... and guess what ?
