Hey guys,
I flashed cm7.1 rc1, it's cool but I found the cell standby cost 40%, and phone idle also takes a lot of juice. My previous rom is arhd 1.10, on which the cell standby only takes 4%. I'm on the virgin's network in Canada. The virgin is acquired by Bell and of course it's using bell's network.
Is this network HSPA only? So in the *#*#4636#*#*, can I set the network mod as WCDMA only? Or by toggling 2G/3G to 3G only? Not sure if this will save some battery?
Switching to 2G only should save you a bit of battery. However, by far the best way to save battery is to switch mobile data off completely when you're not using it. I do this and my battery loses only 2 or 3% on standby overnight.
Switching to 2G wont work as Virgin Mobile/Bell does not have a 2G network backend like rogers or fido only 3G/4G so switching to 2g would make you have no service.
Yes. Virgin/Bell only use 1900MHz, the PCS band for their mobile communication, both voice and data.
In my opinion, use 3G only will save some power because the phone won't scan 2G frequency range. Moreover, setting the band as US band also will limit the scanning scope to save power. But after one day using, I didn't find much enhancement on battery life.
Ah, didn't know that. My apologies.

They act trully. Use 850/1900, bands ( for get the band number ) also if your in a area of low to no signal it kills battery becuase the phone is continues to serch for a signal almost as bad as call for battery. Also give you phone a week to calabrate your battery

if not just calibrate your battery I switched back to android revolution just cause i couldn't deal with the terrible camera app in cyanogen mod. And now display is back to my number one battery killer.
this is a "feature" of CM7.1, i found too
Yes, I also conclude this is a feature of AOSP.
I thought this battery use is a transient value for each process on battery draining, but now I found this is an accumulative statistics. The cell standby and phone idle's high usage make sense.
In the stock firmware, the fact that display always takes majority of the juice doesn't make sense actually, cuz the screen isn't always turned on.
Can somebody be so kind and upload stock buid.prop for Bell AHD?
Wanna see differences between the AT&T and Bell setup - looking for way to enable network type switch in phone info
Thanks
here you go!
please extract it to get the build.prop for a bell AHD
Well, I tried replacing build.prop in hope that will enable band switch but it did not
I would really like to have option enabled in settings or trough phone info.
In phone info i can switch between LTE/GSM/WCDMA and LTE/CDMA/EvDO/GSM/WCDMA.
Any other choice reverts back to LTE/GSM/WCDMA. I have done EB40 battery mod and I am not worried about battery life as I can pull out 2.5 days on medium usage but 70% of my day I do not need LTE so I was hoping to extend battery life even more by switching to EDGE

I dont know what ATT did...
I followed instructions from here: http://forum.xda-developers.com/showthread.php?t=1386383 and I got network switch enabled in settings but when I select GSM only setting does not stick...Reverts back to LTE.
I tried adding ATT 3g APN (wap.cingular) but it wont connect to the data network at all???
Really stuck now.
Generaly I always used 2g data connection when I am at work as I still can get my emails and mms and do some basic browsing and internet radio streaming. Then if I stream videos or download apps or upload large amount of pics I would switch to 3g (LTE in this case)
I wonder does it have anything to do with account provisoning for LTE???
I really would like to have that option enabled and working. I know ATT is in the process of phasing out 2G data on account of LTE but as long as it is available I would like to use it...
After completing the steps in that post and deleting the backups change the operator to maritime. Successfully dropped down to 2G /EDGE. Thanks for this thread. Was hoping someone would post a bit of information on it. Here's some screenshots.

Great - I did it too, bad thing it does not stick after reboot - reverts to auto select network but its better than before
I wonder what the heck is Maritime in network selection...
Anyhow will look more into keeping manual network selection after reboot.

Maritime is another AT&T network. It was actually the default on my Atrix 4G. Sadly, the Atrix HD doesn't display the code for each maritime network. Shouldn't be to hard to switch the default to it if we knew which code it was. Setting the default to Maritime wouldn't help considering there's 3.
Sent from my Motorola Atrix HD MAXX
Very interesting. If set to 3G only on Maritime it displays the 4G without LTE. Through Phone Info, it shows that I'm connected through HSPA as well. Selecting Automatic sticks with HSPA unless I get better LTE service. Seems like 3G is a good balance between speed and battery life.

Is there any proof that disabling LTE saves battery life? In older phones, disabling 3G would save battery life because there were separate chip-sets for 2G and 3G services. That isn't the case now, a single chipset handles all signaling. Thus, there are no chips that are powered down when 4G is disabled. I would expect battery savings to be minimal.
Additionally, because of the increase efficiency of the LTE network (combined with less network loading), your phone will have an open data connection for a much shorter time, when transmitting data.
I've got my AHD on the AT&T network using a StraightTalk AT&T sim. $45.00 unlimited everything. With the APN that straight talk uses, it never searches for LTE. Just on 4g all day long, with no LTE searching at all.

Hi folks
Today I got my i9305 (swapped for i9300).
I'm not interested at all in 4G, it's the 2GB ram i was craving for. Anyways, is it possible to disable 4g completely?
I read 3G and 4G both use the same chip/antenna and therefore disabling 4g is not possible without killing 3g too. Is that true? Would be a bit of a bummer but in the end I stick to edge anyways and fire 3g/4g only up when really needed and disable it asap.
Also, I read the new 3g/4g chip is more energy hungry than the 3g-only chip, even if only 3g networks are selected.
Can someone elaborate on this?
I dont think there is a big difference in battery performance
You can choose WCDMA only on the mobile network options and 4G will be off. I'm not sure if 2G will be off too, though.
Perseus Kernel has some lte energy tweaks.

You are dead wrong.
LTE is power hungry, the i9305 has the same battery as the i9300, you will notice a battery drop.
@OP, I saw somewhere the "trick" to get 4g on the nexus 4, maybe you can try that and see if it works to disable 4g? search it up, it's a code in the dialer.

WCDMA is 3G only. GSM is 2G. The S3 is really missing a setting for WCDMA/GSM only.. this would effectively block 4G and only allow 2G, 3G, HSDPA and HSUPA. I don't need 4G, even for normal browsing HSDPA is pretty fast. Would love the WCDMA/GSM option!

cool, thanks for the hint. But I wonder, does this disable the 4G modem? I think what it does is tell the phone to ignore 4g signals in favor of 3g, but the 4g module is still on (and thus consuming power).
If the 3g and 4g modems are actually on the same chip, we're phucked :silly: I believe this is the case, but I still need someone to confirm this...
afaik 4G will only be active if your contract/the area you are in supports it.
Same scenario for 2G/3G. If your phone is on 3G it will not be using 2G at the same time. Unless you are actually on 4G your 4G is NOT active. I can easily see this as I have both the 9300 and 9305 on which I get very similar battery performance (rom dependant of course). If 4G was active then this would not be the case.
Yes LTE is power hungry but only if you are using it!!!
Point is I notice NO difference between the phones battery so do not overthink the situation and just enjoy the phone.
EDIT: Check this out, will have to see if it actually makes any difference in battery preformance though!

Alright, thanks for your input. I'll take your word for it I just got i9305 yesterday (switched from i9300). I have yet to evaluate the battery behaviour. The WCDMA/GSM Auto option you linked to sure is a must have!
I have Korean Galaxy S3 with 2GB RAM.......from the dial pad i can enter a code and go to hidden settings menu....there i can select gsm/wcdma/lte only options.......... as I don't have a LTE connection but my operator and phone supports it.....in the beginning i got network error messages....although the network connection was always stable and i wasn't disconnected......
so what i guessed from this was that LTE modem was on and even i was connected to 3g it searched for lte and then got rejected by operator and gave error...
so i went to hidden menu and selected "WCDMA only" and now i don't get that error and always connected on 3g.....
from this i conclude that it has stopped searching for LTE connection but is the modem actually turned off.....i don't know...
maybe you can make some sense of this....
Just use a 3G sim.
I've got the LTE, and am using my previous 3G sim on a 3G plan.
You can switch off LTE by installing and app called "Phone Info" from the Play Store.
And under device info set network selection to "WCDMA Preferred". This is essentially the WCDMA/GSM option you're looking for.
I did that and my battery life is much better.

Yip PhoneInfo works well. You can use WCDMA preferred (this will prefer 3G/HSDPA over 2G) or GSM/CDMA PRL auto (this will go with the stronger signal)

Do you have a 4G sim/contract as I can only see this being of benefit if you can actually use 4G or if your network supports it and it tries to connect via 4G before realising your contract does not support 4G. Otherwise it will not use 4G anyway. As I mentioned above I can easily see this as I have both the 9300 and 9305.
I do not have time at the moment but will try next week and see if it actually makes any difference to battery life. Would be nice if it does!
Yeah, I have LTE provisioned on my contract, there's nothing special about the sim though. To be honest I have no idea if the phone will try to attach on LTE and then just fail in the case that you don't have LTE provisioned and as a result use more battery?

Guess only some good old tests will tell us but as I do not really notice any difference in battery life between the 9300 and 9305 (I do not have an LTE contract) I am not holding my breath though but hope to be pleasantly surprised!
This will information not be of much use but anyways:
I was abroad for 4 days and thus had mobile data connection turned off, only using regular cell phone connectivitgy for calls/sms and wifi in between.
The battery life was downright amazing, never managed to get it below 50% for an entire day, even when taking pictures, using wifi + whatsapp and doing calls all the time. I even did play games in between.
No surprise, but still, when mobile data is off and you rely solely on wifi, bettry life is outstanding :good:

Well having tested for over a full day now, I can safely say I see NO difference at all in having 4G disabled if you are not actually on 4G.

i dont think he is wrong at all..
I have Owned a I9300 And I have had the EXACT same battery expereince. So why is he wrong?
Your not ON LTE 24/7 it automatically picks up LTE when needed and Only if you are using the internet. I use the internet the same as the I9300 and I still had to charge my phone every night just like the I9305. I have all widgets that need Network connection and I Always have it set on auto 4g/3g/2g . 100% there is no difference at all. If I use powersaving mode and use my phone on occassion i can have it last almost 2 full days even with LTE set this is with stock kernel. And this is the same i had with the I9300 on stock rom.
But i always use the phone OC at 1700 No undervolt Always have lte on auto. And I using perseus Kenerl and i charge my phone before i sleep. Which is what i did with the I9300 when i had it OC
All this talk about dramatic battery drain.. I dont see it
So is there a problem with battery drain or not ?

Hi,
I was wondering if we can turn off hsdpa to save battery life, i used to have a Captivate and we used this secret menú to disable hsdpa, leaving only the 3G which consume less battery than Hdspa and is faster than 2G, but i can not find this menú on my nexus 4, someone knows how to do it?

[REF] WORKING: How to disable HSPA / HSDPA for better battery life
Hi people.
One way to get longer battery life is to disable HSPA and just use 3G. 3G (UMTS) is not as slow as EDGE/GPRS but doesn't use as much power as HSPA.
Here's a quick comparison of *typical* download speeds:
GPRS: 48 kbit/s, EDGE: 150-200 kbit/s, 3G: 384 kbit/s, HSDPA: 1000 kbit/s
After some searching, I've found a method that actually works for our Galaxy S:
Go to the phone dialer pad and enter this code: *#301279#
Click [2] CHANGE HSPA REVISION
Click [1] RELEASE 99 (HSPA OFF)
Then you should see something like:
CHANGE_R99
HSDPA OFF, HSUPA OFF
Done!
Press the BACK button to exit, or press MENU button then END.
The setting should take effect shortly after you exit the menu. To be sure that the setting take effect, toggle Flight/Airplane mode.
You could store that number in your phone book or speed dial for a quick way to toggle HSPA.
The setting STAYS ACROSS REBOOTS!
If you want to enable HSPA again just go back to the same menu and choose [3] RELEASE 6 (HSDPA/HSUPA).
Just tested it with the XXJPP radio and it really works.
Longer battery life at last!
Quick way is Settings-More-Mobile Networks- Use Only 2g.
Better way is to install a toggle control app that let's you do it in one touch.

HSPA is 3g
Sent from my Nexus 4 using xda app-developers app
Try this code:
*#*#4636#*#* :good:
Yeah the main way is to check "use 2g only" which would give you edge only and may save battery but yes it is very slow.
There is also a toggle 2g app which makes it more convenient, or you can use tasker.
Based on what I've read on the forums I'm pretty sure HSPA is 3g. In which case theres no in between.. if you go through the dialer menu you can choose wcdma/gsm which is 3g/2g. We're used to thinking hspa is 4g but its actually 3g since true 4g is actually LTE. Confusing, I know.
Please correct me if I'm wrong.
HSPA/HSDPA is enhanced 3G. Sometimes referred to as 3G+. It is faster than 3G, but not near as fast as LTE, which is true 4G. I speak mainly for the AT&T network because I spent a lot a time with this on my HTC Inspire. AT&T invested a bit of money enhancing their backhaul to accommodate HSPA. I lived in a marginal area where my Inspire was typically on 3G but, by design of the device, was constantly searching and switching to HSPA and back and forth. This constantly drained my battery and caused dropped calls because it was switching towers when doing this. I ended up having to place a microcell in my home to alleviate this, since there was no way to do it thru the device. I'm not sure how my N4 would act today because I still use that microcell.
The OP was asking how to turn off HSPA. In the context of this phone, that's 3G. The next step down is Edge.

True that. Considering this is considered a developers phone that is unlocked and unbranded, I'm a bit surprised at the limited band selection.
It's a 5 band GSM phone, what more would you want? Other than LTE, obviously, we've done THAT discussion to death
Sent from my Nexus 4 using xda app-developers app
I was referring to the ability to select the bands. When I go into the hidden test menu and try to select a radio band, I get a message that states "Unfortunately, the process com.android.phone has stopped". And yes I know this was done intentionally to hide the LTE band. My point was that I consider that somewhat odd. That is all. With previous phones I found the ability to switch bands useful for signal tests in my area, even though I couldn't always make them stick.
THANK YOU. I can finally enjoy fast (Fast enough for my needs) internet without the blackhole drain of HSPA+. 3g, UMTS, does not drain as much as HSPA+.

turn the data and gps off ,.turn down screen brightness, then you will found very long battery life for you
Hello,
I've been doing some tests and I can prove the 3g circuit of our T's is draining too much battery.
You may think this is a placebo effect but it's not. Numbers are numbers:
- With 3G ON (and no switching only 3g mode) - screen on time it moves within 1:15h - 1:55h
- With only GSM (2g) - screen on time goes easily to 2:45h - 3:20h
The same happens if Wifi is ON, screen on time is the same as with GSM.
The difference in my opinion is huge, I though android version could be the root of the problem but after upgrading to 4.3 (stock version) I experience the same results.Maybe is my phone that has a faulty 3g circuit but if not, I don't understand this as 2g & 3g are supposed to have the same power consumption.

That's the thing. If 3G drains that much battery then I was thinking on developing an app that will do the following:
If screen is on -> connect 3g
else connect 2g
It's very simple and it will save battery time. While screen is off, 2g is actually enough, push notifications aren't that heavy
Sony's STAMINA mode doesn't help me due it disconnects data traffic so I miss all push notifications...they should implement that out of the box, or Google instead...
However, I couldn't find a way using android api to switch network mode...you can switch off the data traffic but not its mode, weird :S anyone knows?
The smart radio feature of Gravity Box will switch to 2G after you turned off the screen and back to 3G when you turn on.
