Obviously we don't need 4G or 3G running when we're just walking about town waiting for phone calls, emails, or texts. Is there any way to reduce battery drain by turning off the 3G EVDO radio and falling back to 1xRTT, in a similar way to how we currently turn off 3G UMTS/HSDPA on an iPhone and fall back to EDGE to preserve battery life?
Any help would be appreciated. Thanks!

I have been thinking about this and would like to know as well.
Just because 3G GSM is not as efficient with battery life as 2G does not necessarily mean the same problem exists for cdma technology, however I do not know for certain and its a good question

Indeed. I don't know. And that's why I'm asking!
A few things might improve battery life:
-Turn off constant GPS; it chews up battery when not needed. It's on by default with the EVO and queried every 3 hours (default) by Sense UI for weather information. You can get the same information based on Cell Tower triangulation without firing up GPS needlessly.
-Sense UI (according to rumor) uses more power in and of itself than the stock Android GUI.
-Froyo (by virtue of JIT) should be more efficient and therefore consume less battery life as well.
One topic I'm not sure on is whether Android can scale CPU clocks automatically based on need, like mobile CPUs for laptops/netbooks do? If not, it should absolutely be implemented, and that would be my next project..
Coming from a samsung moment to the evo i can say that jumping back and fourth between evdo and 1xrtt cancause battery drain. Really theres no great method to combat this other than using common sense. If your not in need of gps- turn it off. Turn off queing for cell towers as well, while it doesnt consume as much power as the gps it does take some resource to triangulate your location. The only other thing i would say is using setcpu and establishing profiles that suit your needs. I.e. screen off can be the lowest cpu setting while battery at 50% you could set your profiles clock speed to sit at 600-700. But thats all providing an app like setcpu will play nice with the evo.

I assure you it does.
I manually set my wife's pixi to 1xrtt and her battery life has increased significantly, had to do some hidden code, so perhaps same for evo
It's ##EVDO# in WebOS. Not sure what the code is in Android.
Is there anyway to boost signal strength on dinc2?

I was just about to ask this too ha. The time I have no signal or 1x is quite a bit more than my incredible 1, which was worse than the dare I had. And its not just a "o the bars don't correlate well with true signal strength"
Its killing the battery.
You would think with all the advancements in cell phones the antenna would be more powerful..

Hey, I'm new here but I was messing around with the phone and noticed that changing the phone from Global settings to CDMA (I'm with Verizon) drastically improved signal, 3G reception, and battery life. My phone can be alive and alright with normal use for about 1.5 to 1.75 days. Maybe this will help? Good luck.
P.S. The phone was new out of the box, then fully charged; global settings on the phone reduced battery life (at least for me) to 4-5 hours of use.
Ima test it out and see if cdma settings help I get about 8 hrs of battery now

But i will say.. my brother has the Moto X... I have the Inc2
Side by side, his signal strength will be at 80 - 90... while mine is 90 - 100.
Not good!
With all the technology around, why can''t they make a phone with consistent radio performance!!!

Unless they were calibrated with the same tools, you can't guarantee they will measure with the same accuracy.
i have a similar question but i am rooted (CM7). in my network settings i have several settings i am currently on CMDA/EvDo auto, my other choices are:
Global
EvDo only
CDMA w/o EvDo
GSM/WCDMA auto
WCDMA only
GSM only
GSM/WCDMA preferred
which is the better setting to maximize my battery and still improve my signal strength? Thanks a bunch!

I'm Running CM7 (THANK GOD) but I still cant find where to set CDMA
I just removed the Sim card That should force it to CDMA, but I am not sure.

Hi My Friends ,
when I use mobile data networking ( GSM & HSPA ) it drains so fast , cant i just go for edge , there is function for it in iphone , you can turn off or on 3g , is there any function in nexus ?
Because it drains so fast , it drains one percentile per a min , it means that battery drains in 2 hours
Google are you kidding us ?
Its not the data. Its probably what you're doing all together. Actively using data means that 1) the screen is on, which is the biggest drain and 2) the processor is actively running, which is the 2nd biggest drain.
If you want to switch to EDGE only, go to Settings > More... > Mobile networks > "Use only 2G networks"
You'll still get about the same battery drain because the screen will still be on, and the processor will still be working. Any savings you get from slower data will probably be wasted by keeping the screen on longer to complete the task.
I'm assuming you just got the phone? Use it regularly for a few days and stop watching your battery % and you'll be fine. Checking your battery just drains more battery...
Believe me i have been doing nothing , and it drains so much fast compared to HTC Sensation , my gf has a htc sensation and it also use 4g and we dont use it , and the result is HTC drains 2 % and mine ( galaxy nexus ) drains 17 % , we dont have any app under working , believe me this phone is the worst second thing ive ever had ( first one is Iphone 4s )

uninstall all your apps.
check all settings of apps still on the phone.
and see if the battery is better.
often its an app that is using a lot of CPU or Data in the background causing it to never really sleep.
Maybe use CPUSpy to see if its the cpu which is causing the drain.

Looks like you might want to go back to the drawing board and spend another 2 years trying to learn Android. Surely with your vast knowledge of smartphones and computers you would have figured out the problem by now. Hint: It's you. Damn, well I gave you the answer.
In all seriousness, you are the reason for the problem. You control the apps installed. You control the permissions these apps are allowed to have. It is your job to monitor activity and make sure none are misbehaving. Don't blame Samsung, Google, or anyone else.

Antennas
Wifi
Consumes more energy per time when trasmitting than mobile data, BUT...
Takes less time to transmit data, espescially large files, so it consumes overall less energy.
Wifi scans for a connection and pings the router less often than mobile data, thus consuming less energy at idle
Bluetooth
Consumes a small amount of power at idle to connect to new devices
Scanning for deveices consumes more energy
While connected, very little energy is consumed unless data is transmitted.
GPS
Unless an application specifically invokes the GPS antenna, it will not consume power
Using constant GPS updates (as in Navigation apps) will consume a large amount of power
Some apps will have bugs in them which will keep GPS on indefinitely. Try reinstalling those applications first, then remove if necessary.
Mobile Data
2G antennas consume the LEAST amount of energy at idle, but because they take so long to trasmit data, they can kill your battery.
3G antennas are Ok at idle, but take less time to transmit data, so are the best all around for traveling around metropilitan areas.
4G Antennas are FAST, but consume the most power. Best to leave these off when in transit, and used for stationary, stable connections
All Antennas consume much more power idling in areas of bad reception. So if you know you're going somewhere with poor reception, and don't need data, turn it off until needed (Settings->Wireless&Networks ->More ->Mobile Networks-> "Data Enabled"; "Data Roming" OFF; "Use Only 2G Networks"
This is from the guide to galaxy nexus battery life

I never turn off Wifi, H+, 3G or GPS. Sometimes I forget to turn off Bluetooth after I get out of my car and just leave it on for the heck of it, that while a blue LED is blinking on all the time to notify me Bluetooth is on. It would still last me the 6-8 hours i'm away from home with regular usage of browsing, checking mail, messaging and stuff until I get back, and even then it would still have some power in it. Lasting only two hours means something is wrong and I doubt it's the data networking. Check background services and widgets refresh intervals.

Hi. Battery drain in sleep mode is really good. Around 0.5 % an hour. But when using 3g internet, battery drain is massive, around 3% per minute. My friend was using his iPhone with similar usage to mine, his drained from 75% to 50%, mine drained from 73% to 20%!
I have brightness on low, GPS and Bluetooth off, and I am using radio 26.13.04.19 which is one that I have found to be good and reliable. Is there anyway to reduce my drain? It's way too much right now. Thank you!

3% per minute while screen is off means your phone isn't going into sleep mode.

No, I think you misunderstand. 3% per minute while using my phone (ie: when screen is on). Like I said, when screen is off, drain is only 0.5% per hour.
Try to switch to EDGE, I had it too before. The drain was caused by a bad and cell tower signal. By switching to EDGE the signal went better, same as the battery drain. Only uses 3G if you're signal/reception is good(above 3 bars).
you can turn off Wifi GPS BT and of course the screen brightness .
iyou need to activate sleep mode beacuse when in this mode you almost dont have battery drain ....

There are some build.prop tweaks that you could try. Related to sleep mode and hsdpa power collapse. Look through this page and add whichever are network and battery saving related (mentioned). Look through your current /system/build.prop and only add what isn't already there. If it's already there, just change the values.

To save my battery I have started to use Tasker, this is a profile manager. For example You can set up your phone to switch On Data and sync your apps every 30 min or more, instead of have it On all the time. There is a lot of options to set up your phone. For me it is working great and it helped me to lower daily battery drain. You can find other Profile Managers on Google Shop.

That doesn't help with the 3% per minute while awake.
And switching data on every 30 minutes often means that you can forget using apps like whatsapp and viber. Most of the time people rely on messages arriving shortly after they were sent.
Image your boyfriend/girlfriend sitting outside in the car and texting you "hurry up! we need to go!!" and you get that message 30 minutes later....
And consider using Llama....it's mostly the same as tasker but free

Hi,
I have stock 4.1.1, so build 3.14.708.28.
I've found that since the last firmware update I have a major battery issue. It takes the form of:
- When WCDMA radio is enabled the battery drain is phenomenal, even with no use. I can drop 30% in 30 minutes at times.
- The battery levels do not appear to be accurate. It will be on 40%, then I reboot and the battery shows at 8%, for example. Only apparent at lower battery levels. This not just a widget thing - you can see it in the Power settings.
Have tried 2 hardware resets, rebooting the bootloader multiple times, uninstalling all software except for stock, monitoring the battery usage stats, using Carat to check for errors over a three week period, etc. No software related issues have been found.
Any ideas on what to do? At the moment I'm just using 2g most of the time, which yields much better results.
thanks,
Andrew

WCDMA preferred mode drains a lot lot of battery as it is always searching for a stronger 3G signal.
I recommend keeping the mode to GSM Auto PRL.

It is good advice when you're on place with weak or no signal, but almost everywhere, especially in towns there's full 3G/HSDPA signal anyway
GSM or 2G networks will be shut down soon anyway and speed on GPRS is not acceptable novadays...

Good tip, thanks. Will try hsdpa only and see how that goes.

Well... Battery issue on my HOX is still present- battery don't last long...
Yesterday flashed latest generic ROM (3.20.401.1), fully charged, cleared battery stats but still same results... Right now down to 32% since morning 8AM, with mild usage...
Well I think it worked for me. I've gone from 4.5 hours of battery life to about 11. Also, my random restarts have stopped.
I guess I can't conclude absolutely that changing to wcdma only was the cause of the improvement, but nothing else has changed at all.
