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

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.

This is the General forum. To answer your question, Yes it would use less battery on WiFi. On a data connection the signal is not a constant and the phone is always looking for a stronger signal.
Thanks, thats what I thought. And ive noticed that connected to wifi my battery lasts a lot longer.

yes. And 4g eats your battery.
When I am only using the phone for data, I use WiFi when available. I turn on airplane mode then activate WiFi.
I don't know about that... when I'm on wifi my battery drains like a mofo. Weapon 3.0 ICS theme faux 1.3 kernel.
On every ROM and Kernel I've tried, Wi-Fi uses much, much less battery than 4G. I haven't tried any of the toggles / battery saving apps though so I'm not sure what effect those might have.

He shouldn't have to. If he's draining faster on WiFi then something is screwy with his setup.
On stock, cyanogenmod 7.1, and cyanogenmod 7.1 with various other kernels I've experienced increased battery drain with wi-fi on and connected with the phone sitting at home the entire day. Turn off wi-fi and let it just use the data connection to T-Mobile and I get drastically increased battery times. I'm assuming those of you who get better battery with wi-fi on are in extremely bad signal areas. Also, if you're on cyanogenmod have you turned off the auto wi-fi disconnect when sleeping feature? If you haven't then your battery life when sleeping should be the same as that of wi-fi turned off.
Wi-fi should always be priority if your in range.
Well my personal experience has been that wi-fi eats up battery like crazy. Same thing happens to the other smartphone users I know around here so I was surprised to see that people get better battery times with wi-fi on. Are you guys completely turning off your cellular radio? I don't like the quality and slight delay of wi-fi calling so my cellular radio stays on when I have wi-fi on.
I don't usually notice much difference between wifi and 3g battery drain here (no 4G for tmo here).
As someone already posted, my drain is worst when 3g signal is poor, like when I'm at work and the metal building interferes with everything.
Have you tried checking logs while connected to wifi to see if maybe some app or service goes crazy?
Nothing fishy going on when wi-fi is on. I get about 10-14 hours on battery with wi-fi on and next to no use of the phone vs somewhere around 20+ hours with wi-fi off and similar extremely light use. I keep meaning to do some more standardized testing where I literally don't touch the phone but life gets in the way and I have to make/answer a call or txt or whatever so I can't nail down any hard numbers. Typical experience on a slow day for me is that if I forget my wi-fi is on, my battery will be somewhere in the 3-5% range when I'm getting ready for bed while if I hadn't left it on, I can go to sleep and wake up and it'll still be hanging in there.

That's true, I've always believed that Wifi eats battery faster because someone(don't remember who) always told me that Wifi uses more battery because it processes data faster, but I always noticed that when I used 4g, it drains a lot faster.
I always blamed it on the ROM, but I can see that it's not the ROM's fault.
I've been working on improving my battery. I've noticed a big improvement by using cpu-editor and super saver app. I've also noticed that battery lasts a lot longer on WiFi than it does on 4g Since 8:30 this morning (7 hours), I've used 33% mostly on WiFi and I think that's pretty good.
So, I was wondering... what can be done to improve battery life when on AT&T? I've tried the new radio, I'm not sire that's made a difference. Maybe it has, hard to tell.

If you're on LTE, you will inevitably use more power than just WiFi, that's just how it works.
If you can kick down to HSPA+ or UMTS you will see significant battery savings.

Thank you for your reply.
I'm in Albany, NY. I've been told we have one LTE tower here, but I've not experienced it yet. I should locate it and drive to it just so I can get a taste of how fast it is.
That said, I use HSPA+, unless I'm on WiFi.

HSPA+ uses more battery than WiFi when actively using it for data, the change just isn't as significant compared to when using the phone on LTE.
Some things you'll want to do to really get battery life savings is to eliminate partial wakelocks, and turn down screen brightness either by using a custom ROM or managing settings manually, as HTC's autobrightness is terrible out of the box and doesn't properly turn down brightness when you need it to, or turn it up when you need it to.
After that, if you don't need to have push email all the time then you can turn off always on mobile data, or manually turn off mobile data when you aren't using it.
Our Russian LTE testers of HTC One XL reports about 1.5-2 hours of LTE tethering. Make your conclusions.

Can someone explain to me how to go from LTE to HSPA+ to EDGE? I've tried looking in the settings but all I can find is a "Mobile network" on/off toggle. There is no option to turn on/off LTE, or HSPA+ or EDGE. It's a bit frustrating. Then in my status bar, the 4G icon is always displayed even when "Mobile network" is off. No data but it still shows up. Is this how it is supposed to be?
BTW, I'm using the stock ROM with Apex Launcher. I do not want to root or use a custom ROM.
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.

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...

Hi,
I am trying to get a clear idea on the battery consumption of N5 on Wifi, LTE and E. If the purpose is to be battery friendly, which one (LTE, Wifi, Edge) should I left my phone on most of the time?
Thank you,
Well id say not WiFi! I use Wi-Fi at home and battery life is OK, it actually depends on how much you use it. I'm usually on my tablet at home and on the road my n5. Idk what E is but I'm thinking it's edge so that's probably better than LTE battery wise.

Wi-Fi is by far, the most battery friendly connection because the device only has to transmit and receive from a very short distance. Mobile data signals have to travel to the cell tower so more power is used the farther away you are from it. Less bars, more power used to communicate with the tower. LTE is best because you get that transmission completed very, very fast. HSDPA is good as well. Edge connection is very slow and makes the device hang waiting on the package to be sent and received, thus using more power in the long run. I usually set my phone to edge when I'm not going to be really using it.
Hope that helps.

You certainly want to be using WiFi at home. I tried going data only for a couple days because it's unlimited and the battery drain especially while idle was much higher than using WiFi. This is with full signal 90% of the time.
WiFi is your friend for extended battery life. Mobile data - whether it's LTE, 3G/HSPA+ or good old Edge/2G will vary in power but it's pinging the towers for signal & cycling, so it will use more data - that is, all other things equal in terms of settings including the newer/est KitKat features.
Wifi whenever you can use it.
As far as cellular, as long as you have a decent signal, faster is always better (so the modem can download what it needs and turn back off). So use LTE if you're going to be using any data. Knock it down to edge (or off entirely) if you don't want to use data at all, or just for the occassional notification.
So Wifi is clearly the best. So when my phone is idle for a long time, let say at night, should I leave it under Edge or Wifi?
I am writing a tasker profile, so I just try to see which one is better in term of battery.

Well you can always put it on airplane mode/turn off the mobile radio and switch on Wi-Fi after to just have Wi-Fi data. The catch is, you will not be receiving any calls or SMS/MMS while you have the mobile radio shut off... unless you're using a VOIP service.
Hi
I tried searching Google, but get a lot of different answers.
I live in an area with a very bad cellular coverage. I always have 1 out of 5 bars and when I turn mobile data on, it is mainly LTE, but jumps a bit between LTE and Edge and rarely H and H+.
Can that cause a lot of battery drain? As I just factory reset my phone to get rid of every change I did. I enabled Stamina Mode, surfed the web for 15 minutes and my phone was at 95%. Is that normal? Because if my math is right, that shouldn't give me more than 5 hours of screen time, while I heard people getting 8+ without Stamina Mode.
Am I missing something or is their some very needed settings to be changed? Sync off, GPS off, bluetooth, Brightness is as low as possible, NFC off, black background (less power consumption), Wifi off and Wifi constant searching off.
U can easly check urself how cell signal draining battery ,first Check how it is with normal H+/LTE then charg it again for 100% and use ur smartphone with plane mode acivated ,now subtract result from 2 "experiment"
Also of note is that black backgrounds mean diddly on our displays. We aren't on OLEDs.
Also, if you ARE in wifi area it's better to be connected to wifi. Wifi is closer than the cell tower and data disconnects when wifi is connected.
On AMOLED/OLED black background helps because each pixel is individually lit (Black means those pixels are off). In LCDs there is a backlight providing illumination for the entire LCD so as long as your screen is on it won't make a differrence what colors are on your screen.
I'm having a similar issue. I have very low cell reception at work, and I can get maybe 4-5 hours SoT throughout the day and am at 10% when I get home. I've tried uninstalling/disabling apps that use a lot of battery, so hopefully it helps. I'll update if by the end of today I'm able to get 7+ hours SoT (which it seems it's on track to doing).
Edit: For clarification, the apps I've uninstalled that I believed to be using a lot of processing power/ram/battery were Facebook, [Facebook] Messenger, and Words with Friends.

Just use an app like Greenify to block apps running in the background when not in use so you dont havr to uninstall them.
Brightness can have a lot to play on this one. I tend to go with manual brightness so there's no ambient sensors working all the while the display is on, and if you are doing anything where you can cope with lower brightness then drop it.
Keep an eye in battery stats for "google play services" as this can go nuts. When this happens sometimes clearing data can help.
I also found that using google+ to backup my photos caused a lot of battery drain.
I have not found facebook or whatsapp etc to affect my battery much personally. I use stamina mode when i'm out and about to keep the phone at sleep while the screen is off.

At my house I get just enough LTE to cause our S3 to constantly switch to LTE then loose it and switch back to H+. Battery life couldn't make it thru one day. ATT removes the screen that let's you control network mode but I found a backdoor method to lock the phone out of LTE. The phone now stays on H+ and battery life easily jumped 40%. That's the primary reason I held out this time for an unlocked non-ATT-crippled phone--so I can easily turn LTE off.
Well, tried have my phone on over night (for a change to test it).
Everything off (mobile data, gps etc).
Used 7% of my power and every app was closed. When I looked at battery drain, 55% was from cell standby and 40-45% was from Phone Idle.
Tonight I will try charge it to 100% again and then let it be in Flight Mode to see.
I struggled to flatten the battery on my phone the first day 70% of the day with the screen on, no wifi enabled or stamina.
Another test would be to change mobile settings to 3G or 2G to see what difference that makes. Under settings, wireless & networks, select more, mobile networks, then network mode.
I would try the above first before making your phone completely unavailable, especially the 2G.

Nice, thank you! Care to check hspa too?

What is that? H/H+?
GSM - Edge
WCDMA - H/H+
LTE - 4g
But I think 4g uses less power than edge, but it is more than in my area there is 1/5 in 4g coverage, 3-4/5 in H/H+ and 5/5 (always) if using edge.
As I see an better connection gives better batterylife, but 4g uses way less than 3g/edge if same cell signal.
But is going to try it next time I get down to my dad. He got 5/5 in LTE signal. So gonna see if it can stay at 100% over night.

Hehe, ok I understand. But HSPA = 3G. [emoji4] I haven't done any rigorous testing, but I think my stand by times are much better using edge (2G) compared to 3G.

I see. But if you change between those, you probs have an better cell signal with 2g (in your area), right?

Nope, coverage is about the same. Generally speaking though, 2G > 3G > 4G when it comes to battery life. That's been the rule for years, but as of late, newer radios have become more efficient with 3G and 4G, thus making the difference less noticeable. YMMV. Would be interesting to see your drainage on 3G as well. ☺

Well could try it tonight.
