Does anyone else set their device to GSM / edge only? I dont have a data plan so there isn't a need for 3G. Also i spend my day in an area of a building that barely receives an edge connection so it keeps the Fuze from switching from 3g to edge to 3g / etc...
Today was the first day (outside of my office) that i used it with 3G off. and the battery only lasted about 4 hours i had only sent / read about 40 text messages in that time too. it is weird.
just looking for input from others that might have the 3g turned off.
thanks!
u mentioned u don't have a data plan... so did you use your wifi extensively?
I have 3G off, but I don't read so many massages my battery keep 2-4 days. I also disabled TF3D.
I have 3G disabled as I have the Euro/Asia TP so 3G doesn't work here in North America. I have a data plan, 3G would be nice but EDGE is enough for my medium email / browsing needs.
I use WiFi only when I need to stream media or download files above 10mb, etc. I fine that my battery lasts 1-2 days, depending on my usage. Also I find my battery lasts longer than it did before, partly I think because I put the phone down sometimes now, and partly because it is now "broken in" properly.
I think it is vital to battery life to disable the radios you are not using, such as bluetooth and WiFi, as those are from a battery's standpoint, the silent killer.
I would also be inclined to agree with majkeljj, in that TF3D really draws a lot of power. I did test this, but I find reduced battery life is worth it, as I like TF3D....for now at least
i started today with
a full charge
egde
TF3D - enabled
no wifi
no BT
and it is crummy to the point where it will be dead later tonight. I dont browse EVER from my phones. I'll try it again tomorrow with the same start and TF3D off.
thanks for the input!
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.

Hi all
Im trying to find a way to make my nexus 5 automatically disable my 3g connection when i connect to my home WiFi, as i have horrendous 3g signal in my home and i think its affecting battery life.
Any ideas?
Thanks
You can always shut it off manually. I personally use Llama, to automate it everything
Sent from my Nexus 5 using Tapatalk
You can turn it off manually. I believe it stops you from sending pictures and receiving pictures through text though.
As for battery life, I don't think it would change anything since it's using WiFi for data as a Primary.

if you are in WiFi, battery drain shouldnt be a problem.. all data will be routed via wifi and only voice and SMS/MMS would come via cell tower...
i suggest wakelock detector to see whats using the most battery
As suggested... If WiFi is on, a week signal won't drain your battery. WiFi off, then of course it will.

This actually happens automatically. However doing it yourself does seem to be a quick fix for some WiFi related issues. Tasker or Llama if you think it will help.

As mentioned: mobile DATA is turned off when wifi is connected.
You don't want to turn off the mobile radio entirely, as then you cannot receive phone calls or texts.
If you're in a low signal area, you'll have a small hit to battery life from this, but it's not anywhere near as bad as not using wifi.
but changing the radio to Edge or 3G when on WiFi should be better for battery life right?
I use the smart radio setting in cataclysm and I think it actually helps a little (indoors I get 2 bars of LTE on average vs 4 on 3G).

No, as it's not using the data services. It's only maintaining base voice capability.

I'm not sure what others are talking about but from personal experience changing from 3g to 2g whilst on wifi did help battery life. People in this thread appear to forget the fact that even without data enabled, poor 3g/LTE signal will still drain more battery compared with having a strong 2G/3G signal as your phone's radio requires more power to maintain connection for base functionality (calls, texts).

If the phone is on WiFi, battery life is not affected much by whatever you switch your connection to. On data, then sure...signal issues are a big factor.
Switching from this to that to this while WiFi is on is really a lot of trouble for maybe a slight difference in battery life. ?

I completely agree with you on the fact that with data enabled on a poor 3G connection, your battery's gonna drain pretty quickly. After doing more research I found that changing from 3G to 2G can reduce power usage of the radio quite considerably (apparently up to 50% when in voice/sms mode only). Now as great as that all sounds, that's only around 50% power usage of the radio and I have no idea how much battery the radio actually uses during idle.. Looking at google's specifications it seems like the radio uses a pretty insignificant amount of battery when in idle (300 hours or so) so a 50% saving in idle radio probably wouldn't make nearly as much difference as say a more contributing factor to battery drain like screen on time or cpu usage. So yeah, I guess I gotta agree with kj2112 here, It's pretty negligible in the grand scheme of things if you're actually using your phone with wifi connected.

If it did make a big difference on WiFi....I'd have terrible battery life at home. There is no 2g on my carrier and my signal at home is horrible. But, I get over 24 hours and 6 plus screen hours always, whether at home (on WiFi always...and usually one bar of radio inside) or at work on LTE.
So for me, the weak signal does next to nothing to my battery.....while on WiFi. WiFi off, I get half those times at home.

I'm not doubting you there, I pretty much summarised why in my previous post. When the radio is idling (connected to wifi) it's using a very small amount of power. Hence why it doesn't make much of a difference reducing an already very small power draw.
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.

So currently wifi kills more battery than 3g!
its been on an hour and already accounts for 13% of todays power use.

Check for am app that's throwing lots of wakelocks or alarms when on Wi-Fi. Some apps think they have free reign to check in all they want when you're not using cell data.

Had the same issue beginning 5.1.1. Turned out keeping the phone only on 5GHz instead of both 2.4 & 5GHz wifi did the trick for me. Try it out if you also have a dual-band wifi router.

Many Playstore apps exist to measure wifi strength & effectiveness. "Wifi Overview 360", "Network Signal Info Pro".
My Sammy S6 has a much better wifi hardware than my cheap, old phones. But my home wifi routers are the same.
Wifi transmissions are bothered by:
1) poor hardware (old, cheap phones, etc), which drains battery with weak signals.
2) radio interference rubbish between the main sender, and your wifi receiver.
3) orientation of the two aerials, in relation to each other; horizontal, angled, vertical, ... (especially if 1), 2) above are bad
4) Whether the receiver unit is facing the main unit, sideways, backwards, frontwards, etc. On poor quality hardware, this is very important.
Being very crippled myself much of my time is just lying in my (nursing) bed. My Samsung Note Pro 12.2 floats above my head, in bed. Smartphones are affected if my head gets between the unit and the main unit.
My main wifi unit is about 20 yards/ meters away, but transmitting diagonally through a thick, metal-rod reinforced, load bearing wall. So I have a hardwired ethernet cable linked to another wifi unit under my bed, getting a faster, less power-wasting signal.
I have this on my work WiFi it drains the battery really quickly even idle it is about 1% per 5mins whilst connected to WiFi. On 3/4g it is significantly less drain.
But at home I don't have the issue battery life is good even on wifi.
It'd be nice to resolve it, have had it since I got my s6 in may so following this thread closely.
I opened my own thread back then which explains my experience a bit more:
