Hi all.
I have had my N1 for a little over a week now, and the battery life i guess is normal for a pda with this power etc, but i read over on modaco that by changing over the settings from CDMA preferred to CDMA only, actually increased the battery life loads! So I tested this and indeed it does nearly double my battery life..
I have also now read from an add for the new HD2 that the battery life is again increased by swithching over to GSM only! Look at the battery details quoted for the HD2 below.
Talk Time –
Up to 320 minutes for WCDMA
Up to 380 minutes for GSM
Standby Time –
Up to 390 hours for WCDMA
Up to 490 hours for GSM
I am now testing GSM only, and guess that the battery life is going to increase yet again, awesome..
this looks promising but T-Mobile has lots of 3G dead spots scattered around even a major city like NYC, meaning if I would set the phone to WCDMA only and put it in my pocket, I would not receive any calls or data when not in a 3G area.

u do know that with WCDMA you will get far better speeds than just plain old gsm right?
Setting it to WCDMA only will actually drain your battery faster if you are in an area with poor 3G. So only use it when you have optimal 3G conditions.

Faster yes. But noway worth the hassle of toggling it on or off. Unless you don't like to charge your phone each night then its not a prob. I use 3G/wifi,music,games and my battery easily survives a day or two.

Thanks for that Amon_RA, and a personel thanks for for RA-nexus-v1.5.3
I guess my phone usage is split 50/50, i.e 50% at work with a max 3G signal, and 50% at home with a weak 3G signal. I definately saw a massive increase in my battery life when on WCDMA only, so changing to GSM should benefit me even more. I live in the UK and am on the Orange network, overall the 3G coverage is not to bad.
I will report back after a couple of days testing.
Good news for me: there is basically no 3G coverage here so guess I'll be GSM all the time. Getting my N1 this afternoon.
Is it just me or am I not seeing a 200% increase? 20% maybe.
how do i actually choose which band to use? been trying and didnt see any options.
in your dialer dial *#*#4636#*#* then go to phone information > set it to WCDMA only (3G only). Default is WCDMA preferred.
thanks! guessed i learned something new today
Hi again everyone..
Well one day into testing GSM only, what a difference in the battery life..
This is my default setting definately when on holiday to save on power, and when I am not using data roaming. But the speed difference is bummer, i.e GSM only gives me GPRS slow-ish speed, and not fast speeds that 3G gives you, if you are in a 3G area that is.
I have now found an easier way to switch bands, well at least between CDMA preferred and GSM only mode's, and you don't have to switch off your N1 or even put it into flight mode anymore.
1-Swap your band to GSM only mode via phone keypad.
2-When you need 3G speed if available just go to settings/wireless & network settings/mobile network settings, and untick box to use only 2G networks.This re activates the CDMA preffered mode.
3-When you want to go back to GSM only mode, re tick 2G box as detailed in 2 above.
If you use GSM, and by extension GPRS, most if not all of your calls will go to voicemail. 2G only means your phone can do either voice OR data at a particular time - eg If you're browsing or reading messages or syncing you wont get calls. Conversely if you're talking on the phone you can't browse the web. This is why 3g is so much better - you can do both simultaneously.
You may already be aware of this but I thought I'd mention it just in case you weren't.

actually when android receives or makes a call on EDGE / GPRS it automatically turns off data to allow the call to get through.
This is a must solution if you are on AT&T, with the phone only being gsm capable for me it has increased my battery life by I say 20-30% and going into settings also and switching to only use 2g networks works amazing.
I wonder if there will ever be an AT&T nexus AT&T thats what all my family use..

AT&T doesn't support this (or didn't a year ago when I last looked into it) for incoming calls, so be careful if you're using AT&T (of course, if you're on AT&T there's no other option).
T-Mobile supports this, so it'll work fine.

thanks alot for this code it helped
I dont know why everyone is treating this GSM vs 3G battery life stuff as if its something new..
Those who remember, the iPhone 3G suffered from the very same issue...
wooo hooo!
Poll in..
Finished testing..
GSM only mode is a definate winner as far as battery life goes, but the down side side is the slow data speed side, and the fact that you can't recieve calls when say surfing, or when data is being downloaded in back ground, it just goes to voice mail... Try it.. change to GSM mode, phone yourself via a land line while surfing etc and see your calls go to voice mail.
The easy switching via the 2G mode does help, and you can swap as and when required, but as alot of my current N1 apps connect to the web for updates etc (beautiful widgets for weather updates, e-mail checking etc) I will stick to CDMA only mode for now, and just use GSM mode when I go on me hols abroad when I don't use data at all.

Receiving calls during 2D data transfer is a feature that needs to be supported by your mobile network. Your mobile operator probably needs to implement a Gs interface and change the Network Operation Mode. That way your phone can be paged during 2G data transfer and you'll be able to receive the call.
guys, I've been struggling with you all that my SGS2 is jumping from 3G <-> H <-> H+ and I don't know if it costs extra battery, but I'm kinda tired with the 1-2 seconds lag whenever I wanna use the data (like browsing).
I would like to know if there's a way to use ONLY HSPA but not the 3G? I know there is a way to disable HSPA leave only 3G, but I want it vice versa, at the end of the day it's an expensive device and I want to use fast connection on it. my old HTC Desire stayed connected to H at all time and I felt good about it.
well, any idea?
If I'm not wrong, I think it's a good thing that it keeps switching between HSPA and 3G. If it needs to download/upload large amount is data, it'll use HSPA and it'll switch back to 3G for normal usage which I think save battery in long term.

WCDMA
Have you tried using WCDMA only mode? This still lags?
For your question, dial *#301279#, change HSPA revision and release 5(HSDPA only). To return to previous setting, release 6.
HSDPA drains the battery a lot. 3g helps when in standby.

This is what I believe as well. The phone should switch to 3G when sleeping / stand-by to save battery... but for some reason, each time I wake my phone up, I can see 'H' on the Data Connection instead of '3G'. If I unlock my screen and wait 5-10 secs, Data then switches to 3G. But if I lock it and unlock again, it's back to 'H'. This has been draining my battery more than when I have WiFi connected.
I've searched for this issue on google, this whole forum but just can't find a post discussing about this issue. Maybe I didn't use the right keywords... I've been searching: "samsung galaxy s2 sleep 3g hsdpa" , something along those lines. Of course I tried combinations like just sleep 3g or sleep hsdpa etc.
If there is a discussion regarding this, could you point me to it please or suggest keywords to search for.

Are you talking about fast dormancy?
When Hspa is turned on when you unlock your phone, maybe there is an app or a widget that calls out for an internet connection? Those widgets that refresh in a couple of minutes maybe? Because in my experience H is only called when data is needed.
I'm aware of Fast Dormancy and the way it works, but definitely not what causing it to stay idle in H mode. I've switched it off before and still the phone wakes up to H signal.
One app I know to use the Data connection every hour is Beautiful Weather widget. I've disabled refresh-on-wake so it will only update hourly.
Isn't fast dormancy detrimental to users who use data on the go frequently? I mean, if I'm on my phone quite regularly, constantly using data, locking, unlocking and using data some more, wouldn't the change from 3G to H+ drain more battery than it saves?

Basically, FD (fast dormacy) enabled, means that your internet connection will be at max speed, of course depending on your carrier speed.
Some ppl say when FD disabled, you get better battery life, but from my experience, nothing changes, you only get a super slow internet connection.
So if you use your internet connection more frequently, just leave it as it is.
Cheers.
I thought it referred to the switch between 3G and H+ to save battery. Can you link me to a proper description?

Search the forum it is there.
Theoretically it saves power by using slower data connection ( if your carrier supports it), but then again if you have wakelocks and they use data connection or you use data connection every action will take you double the time since connection is slow, do the math.
Not all networks use FD .
jje
Absolutely, and I'd really like to know if any Indian carrier supports it or not?

I'm confirmed that my hometowm support the 21M hspa+ network,but why my gs3 can't lock the hspa+ network.When I open the data,H+ just showed at a very short time,and then it turns to H.
And I moddified the build.prop hsxpa=2,and flash the modem.but it just can't lock:crying:who can help me. thanks
I'm pretty sure that phones will only go to H+ if they actually need it. Hence you'll find that if you start requesting data, it will switch over to H+ again, and then revert to basic H when it's done. Probably not an issue.

thanks,I know what you said,but I want to ask is that even it starts requesting data,it just stay at H,not H+.It just show at a very short time ,then it turns to H and alaways to be H.
In which case it's a problem with either your network provider or your phone. I'd suspect your provider primarily; give them a call and see if they can help.

To expand to what anthropolyte said, the GS3 has a Fast Dormancy mode, where it'll connect to H+ network when is truly needed (heavy surfing/streaming, etc), and when the phone is mainly idle or doing light/periodical syncing, it'll switch back down to H or even 3G to conserve battery. As far as I know, Fast Dormancy must be supported by your carrier (which it does in your case) and must have a compatible phone to toggle between different network mode (GSM/HSPDA/UMTS, etc) to increase battery life.

mine alternates between 3g and H+ too. It bumps it up to H+ when I start using apps. The slight lag before it kicks in is not a bad trade off for better battery life.

I am using an AT&T Atrix 4G (rooted and has NottachTrix ROM with 37p radio) in India on BSNL AP circle and I have been getting really poor reception. It is so bad that I can only receive or make calls about 25% of the time. Many times, the phone shows no signal, but often it can't receive or make calls even when there are full bars on it at that moment. I tried using the other popular radio posted here, which is 36p and that showed no difference. Is there another radio that is better suited for this region and mobile operator?
I also have a severe battery life problem. With a brand new battery, it lasts about 24hs on standby, but even with a bit of usage it will not last full day. Sometimes it goes from around 60% to under 10% overnight (in 8hrs or so). I am using JuiceDefender for maximum battery life, and also verified with CPU Spy that the CPU is going into deep sleep as expected. Battery usage always shows "Phone Idle" and "Cell Standby" as the biggest battery consumers. Perhaps, the same problem that is causing bad reception is also causing the battery to go down quickly? I bought it as a used phone and used it on T-Mobile for a few days before leaving US. The battery life was terrible then too, but I thought it was because the battery was getting old, so purchased a new one before leaving.
Even though the reception on T-Mobile was also bad, it was nothing compared to what I am seeing here. Besides, T-Mobile didn't have a good coverage in that area anyway, so the reception was just like most of the other phones I tried there. My guess is that there is nothing wrong with the hardware itself, and the right modem firmware will fix both issues. Could someone who is already using this model in India, preferably with this mobile network comment?

Been using the Atrix for the past 6 months. Have used in AP Docomo, AP Vodafone and Chennai Aircel networks, Reception is top notch.
Everyone knows about the quality of BSNL signal and your problem lies there, IMHO.
Battery life is also awesome.
I used CM nightly and I do not overclock. I found faux kernel to be draining my battery so not using that too.

Interesting... I have heard people say bad things about BSNL signal, but I didn't think it would be this bad, so I was still under the impression that the issue is with the phone. May be I should borrow some dumb nokia phone from someone and confirm/rule out the issue with signal quality
I have't tried CM yet on this because I wanted the blur functionality for the dock, but I am not finding much use for the dock, so may be I will switch to CM one day, if only the support for biometric scanner is added. Thanks for the helpful reply!
Well, since the signal is always alternating, it increases the battery usage, i think
Well, my first concern is the reception. With full bars showing up, i am some times unable to make or receive calls. If his can still be BSNL issue, then I might just have to switch. When the phone is in this state, I have occasionally tried to see if restart would fix it, and though I can't confirm it 100%, I was almost always able to make a call immediately after the reboot. The reason I can't confirm that a reboot fixes he issue is because, there is obviously a few minutes of gap between that might have had external change as well.

Support for the fingerprint sensor is already present in Cyanogenmod 7. Give CM7 a try. The phone is smooth and rock solid.
And as ticiano_arraes suggested, poor reception or network quality has a direct impact on the battery, as the phone keeps trying to get hold of a stronger network.

Nice, I would love to give CM7 a try. Is I said earlier, I am less concerned about the battery life than the reception, as 3 out of the 4 times when I want to make a call, I don't get the signal immediately. Also, callers complain about not able to reach me. This is not my primarily line, so I am able to somehow manage so far, but if the problem is definitely on the network side, I will consider switching to a different service. In any case, I will try CM7 and report back.
What band are you using?2g or 3g?never set it to auto.Set it to GSM ONLY
I use atrix with bsnl 3g sim, cm9 Turk,radio is 100R don't have any signal issues or battery drain if I am using only calls I switch to 2g only otherwise 3g only mode use lot of data if I switch to auto or other radios I had lots of issues but with 100R no issues good signal as well as good data speed so pls try that using for nearly 9 months without issue
This is what I have right now:
- Select network - 2G Only
- Operator selection - Select automatically
I don't have a GSM Only option anywhere.
First try 100R radio I too call& battery issues then switched to this radio now don't have network issue when using 36& 37 radios most of the time my mobile was not reachable even when signal was showing do u use data? If not select 2g only using power Widgets u can easily switch 2g or 3g mode easily try 100R with nottachtrix it was good & if u r interested try Turk cm9 & 100R it gives better battery life than others comparatively

Thank you, will give that a shot now. I found the 100R download link from here: http://forum.xda-developers.com/showpost.php?p=21525149&postcount=8
That post also mentions 30p, did you try that?
I got my mobile with .30 then switched to 36 got severe battery issues & switched to 37 it will show signal but mobile all be not reachable then switched to 100R never looked back try with ur current rom check difference.
I'm on .30P and JB epinter's CM10 rom and signal is top notch, no reception problems, battery life great, from INDIA on tata docomo

If you have the stock ROM it's probably that the main problem is the radio that you are using right now. The radios control the way the antenna communicates and all that stuff. So if you are having bad reception, the antena is searching constantly and making more effort to keep you alive on the mobile network.
Try flashing a new radio, it's too easy. Just find in the forum a radio for your region( but it could be from anywhere, for example i'm in Finland right now but i use the normal att{usa}).
I read that you are using just 2G, that's great for improving battery life, but don't expect a huge amount. I always run in 2G and in HSPA+ when i really need the gps, fast info, etc, I'm always syncing with FB, Twitter, Instagram, listening to music and barely it last a day withe the extended battery(bh6x).
Hope this works for you
btw, ,flashing a new radio doesn't delete the data of your rom, it's so easy
I have now observed the signal quality over 24hrs with the 100R firmware and I think there is marked improvement in quality. There were times when I had no signal and I couldn't make calls, but at least I didn't have a situation when there were bars showing and yet the call didn't go through. Obviously, I need more time to see if what I am seeing is genuine.
On the other hand, I don't think the battery life increased significantly. With very light usage, it went down from 100% to 22% in about 23hrs and 70% of that is in Phone idle. I have attached 3 snapshots taken at different times of the battery usage to show what I mean. May be it is just the stock kernel not fully optimized, so I will give CM7 a try.
I installed cwm touch recovery 5.8.1.8 and wondering if the backup created by this recovery is complete enough for the stock rom so that I can switch back to it if CM7 doesn't work out.

Does this ROM also support biometric scanner? What would be the biggest reason not to use it and go with CM7 instead? Stability?

No, this ROM doesn't support biometric scanner and the stock Camcoder cannot record videos due to Nvidia Driver Issues (3rd party video recording apps work), apart from that sometimes random reboot, rest everything works like WiFi Hotspot, GPS is great, and instead of staying on GB I'd like to stay on JB with these few quirks...

The driver should then be there with CM7 as well as CM9 too right?
