For some reason no matter what build, radio or rom I use BatteryMinder tells me that I will get better life with wifi on vs wifi being off. (check jpegs in attachment)
If i turn mobile data off too I get better battery life as well.
Why is the Mobile network killing my battery?
Hm. Could the email checking be doing it? I would decrease the frequency of that. The processor might be ramping up during some parts of the email checking routine. It's also possible that your WiFi service makes the operation quicker. Negotiating a cellular data connection takes some overhead. Ask a radio expert...

Are you in an area that has poor reception? That can drain the battery pretty quickly. The phone is constantly trying to reconnect to the network.

Hey all,
I have an idea for an application that I think could be really helpful. With more skill and experience, I might be able to write it myself but I lack in both of those fields
The general idea:
An application that can be used to measure the battery consumption, 2G/3G signal LEVEL, and data down/up SPEED over Wifi and cellular data modes, over periods of time. The device should not be moved or interfered with until the process has finished (i.e. an audio notification is used)
This could be useful for comparing various versions of radio and how they perform IN THE USERS GEOGRAPHICAL AREA.
Details:
The app will kill non-critical processes and services, and lock the phone for a short-ish space of time (e.g. an hour) so that it can test without disruption
In this time, it will read and record the cellular signal level (2G or 3G) every minute or so for the hour to find the average signal level and the same for Wi-fi
It could also download a small file using cellular and Wifi connections to test average download speed and upload could also be tested
There could be an 'overnight' mode or a longer time period where the battery level could be recorded over the space of several hours while the connection is idle or even kept alive. A decrease in battery level per hour could then be worked out
All this information is recorded and the radio is then rated in terms of battery consumption, connection strength and speed. The process can be repeated with other radio versions and the user can choose which radio suits them
What do you all think - viable or not?
A very good idea. Users can then publish their results in the forum and the radio choice will be far easier.
Good idea but so many variables, so what may be a good radio for one user may be awful for another...
dial ##DEBUG# from your phone or run the hidden file fieldtrial.exe from your windows folder. it has everything you could ask for regarding radio and consumption.
Hi All!
I have a Diamond 2 I bought 2 months ago.
I tried many roms lately but with most i cannot get more than 15-17h Battery
I dont talk much on the phone...i dont really surf from it...i just have my hotmail linked in it.
I recalibrated the battery on last flash still the same. I am using Nhaohoa rom (build 23529), i m using radio 4.49.25.91. I dont use wifi.
Which consumes less power? 3G or HSPDA? or?
Any can suggest a different rom that is very fast and stable and can give better battery time?
Thanks!!!
(sorry for posting it before in the wrong section)

I cannot give you general information for your other questions, but afaik, 3G (HSDPA is only the faster version of standard UMTS bandwith) consumes more power than GSM (GPRS/EDGE), so I have my TD2 set to use GPRS only. 3G i use only, when necessary. My battery keeps a day, too. But I use my device heavily for making calls and internet, so i guess, thats okay when i have to charge my device so often.
Another thing is, what increases the power consumption is a low signals strength and/or how often you lose your connection. Maybe your signal strength is more stable if you use GPRS only. You can verify, if you have an active data connection even if you not use the internet.
I'm not sure, how much the battery life depends on the rom, but I'm comfortable with my current udk rom.

Hi,
I'm starting this thread to collect informations about using the N1 on a HSDPA network. Over the next weeks I'll be posting stats and infos about my experience on a HSDPA network.
*-----------------------------------------------------*
Tips
*-----------------------------------------------------*
(reserved)
*-----------------------------------------------------*
Battery optimization
*-----------------------------------------------------*
HSDPA seems to be very hard on the battery, and to get the most of your N1 there will be some sacrifice.
What COULD help:
- Dial *#*#4636#*#* and set the phone to "WCDMA Only" in the phone informations.
- Try the app called "battery refresh" on the android store. It will discharge your phone. Then boot into recovery and wipe your battery stats.
- Install setCPU from the android store (1$) and force it to 245/576 while the phone is standby/sleep (thanks djmcnz)
- there's an app on the appstore called JuiceDefender that allow you to disable APN based on time or your location.
What WILL help
- disable sync (push). This have a MAJOR impact on HSDPA network
- and obliviously set brightness to auto or lowest acceptable value.
*-----------------------------------------------------*
Signal optimization
*-----------------------------------------------------*
So far I've tried two different radio rom, and the older 4.03.00.21_2 seem to offer better signal. So you could try using that one.
*-----------------------------------------------------*
Bandwith optimization
*-----------------------------------------------------*
- If you have a rooted N1, you could try in "spare parts" the hotweiss's Radio mod (in miscellaneous). In my case, there's not difference but still could be worth a try.
*-----------------------------------------------------*
N.B. : Fellow canadians, if you are on Bell or Telus with your N1, your are on a HSDPA network.

You could try JuiceDefender, I think that app does exactly that.
I seem to get alot of network connection errors from market, to internet, and some games that use internet.
I noticed my signal is usally full bars but switches alot between 3G and H (HSDPA)
Are my connections errors due to the switching of 3G and H much like some people have issues with EDGE and 3G switching back and forth in certain spots?
Also that *#*#4636#*#* didn't work. EDIT: nevermind, needs to be done on the stock dialer.
I set my network from WCDMA prefered to WCDMA only. See how that works. EDIT: Still switches from 3G to HSDPA...

I believe this is normal behavior. The 'WCDMA only' option disables EDGE network connections so that you only use the 3G/HSDPA.
Cheers
I hope there is a bug on the N1 radios..Cause I can't last 20hrs with 1hr worth of calls..and small use of internet. Yet other people saying they easily go pass 30hrs with heavy use...liars..
I can still get though a full day, business and pleasure on a single charge using HSDPA, WiFi and making calls... lots of calls.
In an average (16h) day I will be connected via 3G for about 10 of those and WiFi for the remaining six. I make about 180 mins of calls a day, 20% of those using the speaker, I have a feed reader with 20 feeds that update constantly, I listen to music to and form work (20mins + 20mins), I might play a game or two and I often read xda and/or download during the day. Brightness at about 55% fixed.
I charge my phone overnight, every night (have been doing this since my original RAZR anyway).
I have never, ever run out of battery during a given day.
Setting the CPU to min in standby is not a good idea - it needs some headroom to actually complete background tasks and 245 is too low IMHO and will be counter-productive. I suggest 245/576.
If your usage is much above mine then I'm not sure how many marginal tips will be needed before it makes a meaningful difference...

I got these errors on T-Mobile as well - since moving over to AT&T with the AT&T version they have completely disappeared.

Well I'm not sure but on mine it switch from 3G to H only when I fetch data. Else it stays on 3G.

Testing Juice Defender now. So far it's an incredible solution to battery drain, if it does what it claims. Will post findings this weekend.

Yep I'm getting the same results here. Juice Defender is the most effective thing I've tried so far. I'll collecting stats about it right now will post later.
I spend a fair amount of the day in areas with intermittent reception.
My battery life is really poor, since I think the phone is frequently looking for a signal that may not exist.
Is there a way to improve this without having to manually turn the cellular radio on and off?
Thanks!
improve the cell reception or the battery?
for battery, settings, wireless and something
mobile networks
uncheck the first 2
You could possibly use something like "locale" which is gps/location based or tasker which is system based, but I'm not 100 percent sure it support something like this. You might also want to try and take a look at the "superapp" by xda. All Apps can be found in the market.
You could use Tasker for this. You can create a profile that disables your cell radio (airplane mode) when there is poor / no reception and checks for cell signal every 10 minutes or so which is customizable. Its not a free app but a great app to invest in.
If you have Wifi where you dont have cell coverage then you could use wifi calling which saves battery as well..
So I just disabled connections optimizer because I was having issues with my hotspot and I get 2-3 times faster 4g LTE speeds now. Call me crazy but it's true, I've tested it by turning it back on and the speed goes back down!!! Anyone else want to test to confirm if it's a fluke or if we are really being throttled by sprint?
Speeds are crap here :/
Connection optimizer tries to pick the "best" connection available, switching connections in the background. I've always turned it off because it prioritizes wi-fi above all others (even when the available wifi connections are considerably slower than the 4G in the area). I think it may have even connected automatically to open wifi hotspots that I had never used before (it's been too long for me to be sure on that point, though). Even when it ultimately decided to stick with the 4G connection, the moment that it took to check other connections would interrupt many downloads and slow down those that managed to keep going - perhaps that's the issue you were experiencing...
But with it turned off, you should enjoy better battery life as well

Thanks for the details. I see that the second post is showing very high download speeds. Why are you saying they are crap?
In reply to the styles 420, I wasn't experiencing overall issues, I just noticed an immediate LTE improvement after I disabled sprint optimizer. When I turned it back off immediate decline. Speed test with connections optimizer on would be around 3mb/s, immediately after turning off optimizer, standing in the exact same location, my speeds are 7-9 mb/s. Please more people test this to see if you see an improvement, doing a before and after a few times with connections optimizer on and off for mobile.
bump - someone else please try this need at least 5-10 people to try.
Turning mine on and off changed it a little bit.
Turned on top pic and bottom pic is turned off. only.
Wow good news that's over triple increase in upload 33% increase in download! Thanking you for the post, anyone else please share?

If you are having problems with your hotspot I found a useful app that stops it from breaking up. "Connections Optimizer" stops disconnections and if the connection is forced off it reconnects more quickly (works best with super access ). At home I make my hotspot through my PC with pda.net. through the hotspot my speeds are actually double what they are through mobile data.
Well piggy where my lte speed is supposed to be way faster i use my wifi in my house. Lte sucks here.
Ya to me my 5-10 mb LTE is bad because I have 170 at home but for people who use LTE a lot outside like me it is a big deal. other people please post your before and after connections optimizer speeds we are seeing big improvements.
This thread isn't about hot spot it is about connections optimizer actually throttling your Internet speed. If you can please post before and after speeds with connections optimizer on and off, testing from your phone with speed test.

My LTE sucks here as well. It depends on the time of day I use it. I can't even use the connections optimizer anymore. If I don't disable it my connection gets interrupted every 10 minutes or so. I use 100gb+ from Sprints network every month so they dial me back. I get around it by installing a new ROM or resetting the SCRTN often. I think that the device is programmed to remember home (where you spend most of your time) and it dials it back there. A new ROM will get up to 10mbs for a day or so and then it kicks back to .5 - 1.5 at home. If I go somewhere else it jumps up to 20.
I don't have WiFi at home right now. If you read the description in the optimizer it says it is designed for the smart switch. So, unless you are somewhere that there is WiFi for it to switch in and out of it does no good.
Read op on Google's policies for WiFi. You will be surprised to find what they say about it. Unless you opt out devices are allowed to make quick connections to anyone's router.
Ya that's normal for 4g to go up and down depending on where you are and how much data you have used. But good to know that your speed does go up with connections optimizer off!!! That's 4/4 people I belive? Anyone else care to test before and after speeds in same location?

I tried it out to get you the picture you requested. I did 4 tests. I was actually getting better speeds with the optimizer on. The forth one didn't show in the total. In my screenshot 1 and 3 are with the optimizer off and 2 is with it on. It's 1mb faster with it on. I'll try again later when I'm not at home.
The 1mb isn't worth leaving it on when it's not plugged in because of battery usage from having to leave the GPS. Also, I don't use it because I get interrupted every few minutes with a notification saying connections optimizer has stopped.
