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.
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.

Deleted Messenger and Facebook just for the sake of it. I don't have the need to be online all the time and the people that want to contact me, have my number.

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.

Just did the tests.
Flightmode - 100% after 8 hours (sleep)
Edge - 99% after 8 hours (sleep)
4g - 93% after 8 hours (sleep)

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.
Hello,
I recently picked up a OP6 and I'm really pleased with it overall but SOT has been a little disappointing. At least I think it has depending which battery app I consult!
Accubattery Pro thinks I'm getting an average 8h 16m of SOT (this is definitely not correct!).
GSM Battery Monitor PRO reckons 4h 46m of SOT (which still seems a bit high).
In the battery tab of the Settings menu it reckons having used 65% of my battery I've had 2h 50m SOT (ie. from 100% after 2hr 50m of SOT I'm now sitting on 35%). I think this equates to about 4h 30m of SOT if I continued at the same pace. I guess this tallies pretty closely to the GSM Battery Monitor PRO so maybe this is about accurate.
I've followed the guide here to get the most SOT but 4h 30m seems on the low given that I don't game or stream, don't have FB installed etc. This is purely webbrowsing, a bit of YT and a podcast app (listening to downloaded podcasts rather than streamed if that makes a difference).
Nothing in the battery stats seems that unusual (please see attached). What does seem a little odd is that I'm not in a great spot for mobile reception but looking at the stats it doesn't look like the radio is draining the battery.
Any advice on how to delve deeper? I'm 100% stock and not rooted.
Any advice for a OP newbie is much appreciated
Hmmmm Better Battery Stats seems to tell a rather different story especially around the radio reception.
Again any advice much appreciated!
The poor signal is killing you. When the signal is poor it pumps out more juice trying to stay connected. If you will be in an area with poor signal and won't be using your phone I suggest putting it in airplane mode or maybe setting it to 3G as a proof of concept. If your battery is much better then you found your issue
Also wifi scanning is turned on,which is a battery killer. Turn it off and you can see a great difference

Thanks Spartan! The problem is poor indoor reception with the signal constantly cutting in and out. As such airplane mode may be the ultimate option but obviously it's a bit of a bummer as a long term solution! I'm going to try another provider which claims to have better indoor coverage in my area.
Question #1 - you mention trying setting to 3G as a proof of concept. Is that because a 2G/3G uses less power to connect than searching for a 4G connection? Should I try the 2G only option before the 3G one?
Question #2 - if I do try 2G/3G (before trying airplane mode) should I turn off mobile data too or does that make a difference?
Question #3 - I'm guessing having 2 sims installed makes the problem even worse as both are constantly calling for signal? I typically use one for data and one for voice.
Question #4 - when some folks post their battery graphs they have a picture which shows the mobile and wifi signal (see attached as an example). I don't seem to be able to find this. Was it removed from the latest update as the battery section seems to have changed a bit.
Thanks again!

Thanks for taking the time to reply!
Strangely I don't think I do have wifi scanning on (please see attached screenshots)! Location services are also off.
Are you thinking I do because the wifi is on 100% of the time?
Could this be because an app is somehow keeping it awake?
Hmmm can't see an option to check if "keep wifi on during sleep" is enabled. Has this been removed from 9.0.2?
My brand new p20 pro is now having a battery drain issue, something thag i never had with my old p9 lite device
Adter updating it to emui 9, my phone drains overnight. I left it at 90% and it drained 5-6% battery.
What is going on!?
Go to Settings -> Battery -> Battery Usage and check what drains your battery. Usually it's bad cellular network reception (you will see more "Cell standby") or some app.
Just a note - AOD (always-on-display) does drain your battery (yes, OLED display, black colours, bla-bla-bla, just test yourself), so if you want it enabled (because it's convenient, I use it too) keep your phone face down on your desk/bedside when you don't need it.

Yes., the cellular standby thing is draining my battery, also AOD drains like very little power from the phone. I set it to turn off itself at 22:00PM and turn on in the morning at 7

Well that is your answer. If you have bad cellular network signal you phone will drain battery faster to keep you connected. Just to confirm it you can try using your phone with a different carrier (that has better coverage) for a day or two and see if battery doesn't drain so fast.

I always have great signal but how comes it goes low or drains the battery when i have full signal?
I guess I should stick to 4g instead of 3g?
Go to System -> Settings -> About phone -> Status -> Network
Check the values there and google what is considered "good".
Signal quality affects battery drain because any fluctuations make the modem in your phone work harder (scan more frequently for better signal, jump between frequencies etc.), this can be caused by weak cellular signal, changing between bands/frequencies (3G/4G), changing between cellular network controllers (antennas) etc.
Taking it further, it can be also a hardware problem in a particular device.
P.S. I don't know your exact situation and never saw or used your device, and everything I say may be completely irrelevant, I'm just giving a lead to look into.
So I have the note 10+ 5G from T-mobile and the battery life is terrible, is anyone else in the same boat as me? Not sure what's happening because I had an S10 5G and battery on that was amazing but for some reason on this phone its terrible.
Yes, I have this problem and I have not found a solution
Could this be related to the GPS + 5G issue people are seeing? GPS is having issues locking on when 5G radio is in use.
he 5G radio of the terminal is a problem when the antenna that it emits, does it in a frequency and distance that is not yours ...
If the terminal is switching between 4G and 5G it consumes a lot of battery
It is more rare, the case, if as it says with an S105G and a Note105G has a different problem, especially when both terminals are cousins with screen variables (spen) and camera settings and little else
