...how did you freaking do it? I have tried everything from the 1.47 to the 1.54 and still nothing. I am living in Japan using the Cingular/AT&T 8525 and am always ...constantly connected to the 3G( i always have either the "3g" or "H" symbol showing. Is there some other trick i can do to get my battery to last me through the day? I cant use my phone on the weekends cause of this issue...I will be away from a usb port for too long lol.
I hear there is GPRS network in Japan...is there a way you guys are connecting to that instead when the phone is idle to conserve battery life.
The thing I dont get is there HAS to be a way to fix this because my non PDA phone (issued to me by softbank) has great battery life and it is using the 3G network as well. It must be using some other kind of band or something to preserve its life. I hate having to switch to my crappy phone on the weekends because of battery life...please help me out guys. Thanks.
P.S. I owe this site so much ...as it is because of this site I am able to even use my phone here. THx in advance.
phone: cingular 8525
rom: black satin
radio: 1.54.07.00
(got mms, live ...and all the other stuff working thx to u all..just the battery is left)
not a softbank user, but you can try and disable 3g using a comm managers that has the 3g button.
like this one:
http://forum.xda-developers.com/showthread.php?t=320239
see post #24 for the one with a 3g button.
you other option would be to get an extended battery, see the threads in the accessories subforum
I was using the Black Satin ROM for awhile and my battery life was really short. Same thing with K's Roms. They both ran nice and fast, but the battery was almost dead before I left work.
i switched to the latest HTC WWE Rom. Battery life was instantly better. Lasts almost 2 days. I have a Softbank X01HT in the US and connect to AT&T 3G service. I get corporate email, so Active Sync is constantly running too.
hmm interesting suggestions I'll have to try them (yes the xtended battery one too) However, are you connected to the 3g network constantly..cause I am, and I'm almost certain that is what the culprit is. I am just baffled how other phones here manage last long here, I know I am doing something wrong in my connection settings. If i turn 3g off, phone can no longer recieve calls and basically stops being a phone. Dayum.
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.
Hey XDA,
I'm running Android Revolution HD 3.0.0 with S-OFF and SuperCID. I am using Mobilicity as my carrier. When I first installed Revolution HD, I did not back up my APN's (it didn't say to do that in guide). After booting up for the first time, I was unable to use Mobile Network until I posted here asking why it wouldn't work, and I was told to put my APN's in.
After putting the APN in for Mobilicity, Mobile Network began to work. Here's the problem though - my phone is trying to use 4G on a network that hardly supports 3.5G. Prior to installing Revolution HD, my phone would switch between using 3G and HSDPA to manage battery consumption better. Now when I turn Mobile Network on, it consistently stays on 4G, burning up more power than before.
I can tell you that 4G is useless on Mobilicity because my data speeds are about 2Mbps download (Speedtest.net App).
Could someone provide me with APN to disable 4G from turning on, or if a different APN is not the solution, provide me with an alternative method.
Thank you so much XDA, you've been great,
Robert
Actually ARHD is based on T-Mobile's ICS, which actually switches between 3G and H (on T-Mobile they label it 4G but it's actually H), as I was saying, it actually switches but T-Mobile had HTC modify the system files to show 4G whether the phone is on 3G or H, it just shows 4G all the time, so calm down.
Next point is, your phone switching between 3G and 4G, it's not a form of saving power, it's just your phone showing what coverage it has, therefore your phone is constantly switching between the two, so your power consumption isn't to blame on your coverage if you're in basically the same areas as you were before flashing and your coverage remains similar, but most likely on some programs you have running in the background or well, you just find the phone more usable with ARHD and you're just glued to it more than you used to be. APN settings have nothing to do with 3G or 4G, most if not all carriers use a general apn, it's upto the devices capabilities to determine what data type would connect and what data coverage they provide.
Alternative to reduce power us would be to switch your phone to GSM (2G) coverage only, which would be slow, compared to your current 3G.
Okay thank you for your reply, but I will dispute the fact that ARHD does not use more power than Stock (or just the same).
Using the built in battery monitor, it shows me how fast my battery dies based on the type of usage (it has that graph thing, i'm pretty sure most android phone have it). The phone remains pretty much stagnant with battery usage when its screen is off, but when I turn the screen on, BAM, the battery begins falling vertically. If I get a chance I will upload a picture of my battery usage.
It is literally the same as stock, I honestly get no better battery life with ARHD than before. Although I am not saying that ARHD does not have its advantages such as running the OS much smoother and ICS being awesome.
Robert
Check if your brightness level is too high, I use auto brightness, ARHD is basically stock, just tweaked and a few additions to make it better and smoother.
You can also check the Amaze Bible thread for tips and tricks on improving battery life, it's a general list, so should be able to help, at least a bit.
Anyone who has LTE care to compare?
Some say that the integrated LTE modem means that LTE won't drain your battery any more than 3G will. I highly, highly doubt it (just my guess).
Thanks
im not sure how clearly i can explain this so bare with me here and tell me if you have no idea what im talking about.
the 3g (cdma) and 4g (lte) radios are both built into the processor so right off the bat they use less power than usual but since there is no lte anywhere yet, no one can accurately say just how much it will use but from what i have been reading, people have been ball parking it and saying that it shouldn't use any more battery than the 3g. their reasoning behind this is the fact that the setting for 3g is tied to the lte so if you turn on the 3g radio your essentially turning on both at the same time and lte will connect and take over the 3g and switch to the lte network whenever possible. now you can set it to only use 3g when you turn on the 3g radio but then there is no other way to toggle lte. since i got my phone i have had it so that it turns them both on at the same time and since i have seen no severe drain i would have to say that if it was infact using the lte network that it wouldn't use anymore than the 3g would at any other time (if i had to guess)
to help explain what i am talking about with the settings, here is a few pics that should make it clearer.

edit: so in short, no, it won't drain any more battery
That would be awesome. My Samsung Epic sucked the battery dry when 4G was turned on, so I never used it.
The goal with Sprint is to REPLACE 3G with 4G, and not just have it as a secondary like Wimax, or Verizon LTE is now. They are tuning is so much in battery efficiency so that it drains no more, if not less than 3G, since LTE can burst a dl quickly then go back into idle mode much more than 3G, when in use it should take less battery in theory.

I understand the theory better now, but in practice, it seems that the AT&T version of the One X does drain more battery? Although you can not turn off LTE so I'm not sure how people are comparing it to HSPA+.

I'm thinking the same way you are,no LTE here yet of course,but I do have it set to 3g,LTE mode not 3g only and have been getting excellent battery life.I'm assuming it must at least occasionally check for LTE coverage.
Of course, no actual LTE yet. But I have run full days with LTE on and off and have noticed little or no difference in battery life. Maybe a little better data speed even on 3g, but not enough in my area to prove it with speedtest.
I believe what it is is the Radio no matter what looks for a signal from CDMA or LTE either way BUT I believe the options only opts as to what type of signal is allowed to be USED by the radio as the primary signal technology. So basically either way it searches for both since they are both integrated into one on the processor but accepts the best one available according to the settings in OS(Best As In LTE if available and CDMA if not, not Best as in terms of signal strength).

Your defiance astounds and impresses me.
Believe that both 3G and LTE run on the 1900 radio, where the WIMAX used a 2500 separate radio that killed the WIMAX battery life. Plus the LTE phone battery life with the larger battery and ICS (and less HTC crapware polling the network all the time) has lasted all day with moderate use and power left to spare.
Was disappointed that there wasn't an easy switch to turn off the LTE like in WIMAX phones but then if both 3g and LTE are truly tied together that it would be impossible to turn off.
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

Regarding bsnl signal I have six phones in my home using bsnl I m in a poor signal area using 100R I have better signal than e71,n900 I'm using so try it with ur current from so u can check difference

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

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?

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?
