Yeah, I get a variety of reminders from Astrid through the day. I base most of my tasks at work around it. It vibrates each time they remind me.

How would I check I'm on GSM auto? I think I am, it's something like #*#*36*#*# isn't it?

I guess Wavesecure will not use much more than Google Latitude which updates my position every half hour or so? Can these updates be slowed?
[Nexus One General] rj3005:
Down to 61% after 18 hours, 3G and sync on, used 1h Spotify, 30 minutes reading news and a couple of messages.... at least it´s much better then my milestone was
[Nexus One General] theloginwithnoname:
That's it, star hash star hash I N F O hash star hash star - Preferred Network Type.

Latitude or, more correctly My Location (which Latitude uses), is a battery drainer as it uses 2/3G radio *and* GPS, if you allow it. Battery loss went up about 1% with it on, but as I use it, I'll take the hit.

I know nothing about Wavesecure and/or how to slow it - my preference would be for My Location to update my position as the cell I'm connected to changes; this may be the way it works at present, I don't know.
[Nexus One General] 1991stonecold:
Just been on vacation and to avoid roaming I disabled 3G and also wifi (vacation!!!).

122 hours and still 22% left! Used it for max 10 messages and 20 minutes of talk.

It is still far from 290 hours according to technical specification on google/phone.

Any other low end nokia phone would still say 100% after 5 days of standby!
[Nexus One General] SiNJiN76:
Phone use to die @ approximately 15%, but now it goes all the way down to 1% an probably 0 because it'll sty on 1% for quite a while. This just recently started on a Froyo ROM and has carried over to CM 508.
[Nexus One General] naturefreak85:
See my Backflip (and I suspect Nexus One as well) had been set for WCDMA Preferred, which meant it was constantly looking for a 3G signal whenever the signal downgraded, burning through the battery like nothing else. When I get my N1 back I'll test out with WCDMA Only vs GSM Auto and see which gives me better battery life.
[Nexus One General] RogerPodacter:
how did you get your battery to go all the way down to zero? because mine has always died at 8% and nothing i can do to change it. i've tried everything.
[Nexus One General] RogerPodacter:
it gets the list from your carrier. when you enable gsm auto (prl) it will briefly swith to EDGE, grab the list, then switch back to 3g. this improved my standby time significantly. now if i unplug my phone and dont use it, it will stay at 100% for the first few hours. before it would go down to 95-96% in the first hour even without using the phone.

but it doesnt change much when you are actually using the device, i.e. screen on.
[Nexus One General] AndyCr15:
I tried GSM auto and it didn't seem to connect properly. Dropbox wouldn't do anything, if I opened a page, it loaded a third and then seemed to hang :(
[Nexus One General] AndyCr15:
So, I'm back on WCDMA or whatever it was. At home from 11pm on Wifi though, 12 hours later I've gone from 54% to 36% that's 1½%ph. I don't think I've ever had that good before!

I've removed my 'Power Time' battery monitor widget and have switched back to pershoots latest 0619 kernel.

I'm also finding FroYo's data disabling setting much better than the APN changing alternatives. Connection seems to almost come straight back.

Do people find selecting 2G is a good battery saver? I'm sure I tried it before and it didn't help. Maybe instead of a 5 second use of 3G it just means a 50 second use of 2G?

Any ideas why my GSM auto didn't work? (Orange, London)
[Nexus One General] theloginwithnoname:
Good stuff. On my second charge since installing 0619 and getting considerably less from the battery than after the first charge. Will see what the third charge brings...

I would say it does save battery going to 2G but I wouldn't say it would be a massive saving, unless you're often in an area with virtually non-existent 3G coverage and it constantly switches between.

Depends what traffic your device is generating - web pages, yes; background push messages, no.

Shonky network? ;) It could be that orange don't provide a list?

When you said you opened a third of a web page, was it indicating 3G/H at the time? Did it flick between? Try different site? What was the PPP info when connected (in testing/INFO screen)? Try it again, drop into terminal and do a few network tests - ping www.google.co.uk, traceroute -d www.bbc.co.uk, etc
[Nexus One General] AndyCr15:
Oh.... GSM auto appears to be working today. Now I just need a FroYo widget to switch 'Data enabled' :)
[Nexus One General] AndyCr15:
So, I came off charge last night at exactly 5pm. Today I put it back on at exactly 6pm @14%. That's the best I've had yet.

While on WiFi at home it moved 15% in 12 hours... but as soon as I go outside, it starts to plummet at 5-7% an hour, almost regardless to what I do. For an hour I turned data off and it went back to around 2% an hour.

After the morning of bad consumption and some bad connection on GSM auto, I went back to WCDMA again... but got similar results.

I just read someone uses WCDMA only, while I use preferred. I wonder if that might help? I really need to figure how people have data on and still get usage like I had with WiFi on. When I'm at home is not when I need the battery to last :(
[Nexus One General] hah2110:
Its the heat outside, happens to me too.
[Nexus One General] AndyCr15:
And turning off data cools down my phone? I'm sorry, I don't believe that's it.
[Nexus One General] theloginwithnoname:
Could be that 3G (or GSM radio generally) generates more heat?

Since the warmer weather this week, my phone is getting rather hot on charge. Twice I've seen 37 degrees in OS monitor and it is actually too hot to press my palm on the front or back - is this safe?! Combined with my potentially-under capacity battery, I may be phoning HTC for a replacement soon...

btw I got 1361mAh in OS Mon whilst charging with phone on today - bonkers.
[Nexus One General] theloginwithnoname:
WCDMA preferred - it tries 3G first, drops to 2G if too weak, and gives no signal if no 2G

WCDMA only - it tries 3G first and gives no signal if no 3G

GSM auto (PRL) - it tries known 3G networks first, drops to known 2G networks if too weak, and gives no signal if no known 2G networks

i.e. with 'only', if you're not in a 3G area, you'll get no calls - never mind data!
[Nexus One General] Wylker:
Well, I tried the initial non-public release of 2.2 and had TERRIBLE battery life. As in full to dead in 4-5 hours doing nothing but idling/making a few calls. I have been holding out hoping the public release would fix this, but alas, I put FRF82 on (Kangs final .9) and all my battery problems are back :(

I feel like it has to be the new froyo radio, as this is a different rom and kernel than what I had before. I'll try a .35 kernel next, but my hopes are low.
[Nexus One General] ram130:
Well if it was a problem with froyo radio I wouldn't be getting over 20-30hours with moderate usage. Thats with 3hour display on time, 1hour worth of calls(sometimes two)....and browsing, texting. All on stock.

Also if it was I'm sure the XDA boards would be flooded by now. The problem is with you. Either get a swap or new battery. Also if you only had the phone less than a month, give it time.
[Nexus One General] blas4me:
Battery life

Mines ends with M, and I have a extended one that I don't need to use, because I have no issues with battery life. I spend hours on the web, playing games, downloading videos, roms, music, apps, and flashing the latest roms to see what they offer, and if I like it I perfom a nandroid. I've been off the charger since 10'oclock & it's 6 now, and I only lost 1 bar on the battery graph. I'm so used to having to keep my G1 plugged in, that I keep checking the N1, and I have no drain, expecially if I'm not using it, all I've been doing today is texting and answering emails. What I really need is a 32GB sdcard, because my little 8GB is like 96% full. Try to get google to send you a replacement battery. I read the specs for N1, and it said 7 hours talk time and 24 hours standby. So maybe you got a bad batch, it happens with electronics.
[Nexus One General] ram130:
Actually my battery had improved, it more than double. I use to get 8-10hours, now its around 15-31hours depending on how heavy i use it. Today I made 2hr worth of calls, use the phone for over 2 30min straight(display on time). Texting and browsing the web, 3G and wifi on and my battery lasted 15hours with 15% left. This is with the original battery I got with my phone. I even got 2 extra battery free. I guess the phone only needed time.:D
[Nexus One General] cpm:
I'm experiencing exactly the same. Eats battery while not on wifi. If at home on wifi battery lasts really well. I use GSM Auto PRL. I've also tried removing widgets, turning off background data/sync etc. Bluetooth always off. GPS is usually on for WaveSecure, but rarely do I notice being used.

My usage would mainly be data related e.g. browsing, email etc rather than voice calls.

I also have second eBay battery and that's the same, bad battery life when off wifi.

I'm on 3ireland network.

One thing I can think of is, as far as I know, 3ireland HAS NO EDGE - I wonder does that have anything to do with it? Also when the Three network drops to 2G it actually uses the Vodafone network.

I use a 3 pin direct wall charger I got with the phone which is direct from Google. I also have a slower wall charger I got from my purchase of the spare battery from eBay. That doesn't seem any better.

I'm also on FroYo 2.2 FRF83, but that hasn't made any noticeable difference to battery life.
[Nexus One General] ram130:
I'm losing 1-2% per hour on T-Mobile 3G network with WCDMA only. I suggest you go on WCDMA only if you don't have a EDGE network or have good 3G. Also get rid of that news app widget. If you can set most of your social networks to update like once a hour or two and not all the time.
[Nexus One General] Mokurex:
After updating to Froyo, my battery life has been going downhill, and I've been using the phone the same way as I did with Eclair. This is just sad.
[Nexus One General] ecapox:
Since updating to FRF85B my battery life has changed for the better. Not sure how much, but i went to bed last night with 1/4 battery and when i woke up this morning, it was still on and didnt give me the "You have less than 15% battery left" message. On EPE54B that was NEVER the case.
[Nexus One General] cpm:
As far as I understand, the problem with WCDMA Only is that it won't drop back to 2G if you're in a bad 3G spot? If I'm out and about I may need the phone to switch to 2G when 3G isn't available.

Is there a radio option for 3G/2G with no Edge scanning?
[Nexus One General] bigmout:
After 24 hours of light-moderate use (mostly web surfing and streaming audio over wifi and 3G) I'm at 40% battery. Wifi, gps, and sync are on, but bluetooth is off. Screen is set to auto brightness. Email is set to fetch every 30 minutes. Phone is running Android 2.2.
[Nexus One General] decoyjoe:
So I don't know what's going on with my battery. I unplugged it from a full charge 1hr and 15min ago. Battery usage shows 79% display usage at only 11min usage time. However my battery is already at 89%. I lost over 10% of battery in 1 hour with it being almost entirely on standby. This is all on 2.1. Any ideas what's going on?
[Nexus One General] AndyCr15:
Hmm, two days ago I had an amazing battery day. With light to medium use (2 hours podcast listening, a few texts and maybe 20-50 minutes screen on) it managed 3% per hour through the hole day. After 15 hours I think I was still 50%+

The very next day I've averaged just over 5% per hour, with similar use.

The only real difference is the first day I ran down to less than 20%, turned off and charged with it turned off. The next day, I was around 50% when I plugged in and charged with it on... much worse life.

Day 1 it stayed on 100% charge for 2 hours, day 2 it dropped 1% almost instantly...

Which was the bigger factor, charging while off, or charging from 20%?
[Nexus One General] Raymond77:
Froyo has definitely improved my battery life. I got a day and a bit before, now can get 48 hours with light usage.

In practise it means that I can use my phone fairly heavily with the confidence that I will get a full day out of it, whereas before I've run completely out in 12 hours!
[Nexus One General] ram130:
Yep great battery life with Froyo! Some people phones are just mad buggy..get a swap!
[Nexus One General] naturefreak85:
After a new battery, breaking in the new battery, and further playing around yesterday determined the fact that my battery clearly isn't the problem (at least in my opinion.) I used my phone for about 2 hours and 45 minutes total. From my understanding I should have gotten more time out of the battery than just under 24 hours. Now I could be wrong about this, so I have attached my type out of the log. In the 4 minutes it took me to copy the log and type it out, I lost another 2 percent (and my display is on auto brightness and wifi/bt/gps are off) So yea, 2 hours 34 minutes of display, and 3 minutes of phone calls, = a battery that will last under 24 hours. I'm losing 1-2% per hour while the phone is just doing nothing (except polling twitter every 15 minutes, but that is taking the minimal battery life according to the log)

Display 59% 2Hrs, 34 Minutes 38 seconds

Cell Standby 11% 20 Hrs 31 Minutes 6 Seconds time w/o signal 0%

Phone Idle 9% Time on 17hrs 56 Minutes 32 Seconds

Android System 6% CPU Total 19m 30 seconds CPU Foreground 7s Data Sent 96.36KB Data Received 185.04KB

Aldiko 4% CPU Total 14m 23S CPU Foreground 12m 36s

Voice Calls 3% 2m 37s

Twidroid Pro 2% CPU total 7m 43s CPU Foreground 6m17s

Android OS 2% CPU Total 7m 2s Data Sent 22.98KB Data Received 243.84KB

Mediaserver 2% CPU Total 5m18s

akmd 2% 4m22s

Total Time? 20h 31m 10s Percentage Left? 12%

Time Taken to Type out this data? 4 minutes

Percentage after typing out data? 10%

This is ultra light usage for me and as you can see, I barely get to use my phone. A total of under 3 hours of use and the rest standby.
[Nexus One General] AndyCr15:
Really? I would have said 2½ hours in a day is quite a lot of time to have your screen on? I doubt I get that high. Anyone else?
[Nexus One General] bigmout:
First, that isn't terrible battery life, especially given that your display was on most of the time you used it. Were you surfing the web a lot or something? Touching the display is the quickest way to burn battery life, in my experience -- far more important than brightness.

Second, I would turn off the twitter feed and see if that makes a difference. I know checking email every fifteen minutes burns my battery pretty quickly.

Third, have you done the trick recommended by HTC? If not, charge your phone until it's 100%. Unplug the phone and power off. Plug the phone back into the charger and charge again until the green light comes on. Now unplug the phone and power on. Power off a second time, plug in the phone and charge until the light is green. Unplug and power on, and you're good to go.

PS: Another tip -- switch your wifi sleep setting to "never." It may be using 3g for those twitter updates after wifi goes to sleep.
[Nexus One General] naturefreak85:
Mostly when using the display I was browsing through my twitter feed quickly, and occasionally opening a book or checking an email. I may be in a minority, but I prefer to use the trackball to navigate the device.

Most of the time? 2 hours and 45 minutes is not even close to "most of the time", I also always choose to charge my phone when it is off. Normally I charge at night. The fact is, if 2.75 hours of display will take 60% of the battery, that's way too much. That means that in that 2.75 hours it draing almost 60% of the battery. Considering twitter is only taking 2% of the battery, I don't think that's draining the unit that much. This battery life is also only what I get on the weekends, when I hardly use the device. Normally during the week, I'm lucky if I can make it through an 8 hour day. Considering I had an iPhone that I could have the display on for over 3 hours total and only use 20-30% of the battery, something doesn't seem to add up. But that could just be me.

Also forgot to mention, I tend to lost on average 2% within the first 30 minutes of the device being on and with under 10 minutes of screen time. Even with a loose interpretation of the device usage, that still isn't good battery life. Plus if I lost 2% in 4 minutes when typing out that post, that means that the screen can only be on for 3.3 hours before the battery is fully drained. So if I was supposed to get up to the 7 hours of battery life with video playback, I am woefully under such.

Attempting to play music? Forget about it, 20 minutes of music will drain me 5% (and it's music from an SD card) So I can only get 6 hours of music before the battery dies. Quite a bit under the 20 hours (with average usage, expecting 12-15.)
[Nexus One General] RogerPodacter:
Google's official battery specs say 6.5 hours continuous web browsing or video playback. That is the "screen always on" benchmark. If you are using your phone for 3 of those hours (2 hours 45 min you say) in ADDITION to full 24 hours of use, that is spot on battery life. Exactly what the official specs say it should be. You are still running the radio standby, OS idle, etc the rest of that time. Seems pretty obvious to me.
[Nexus One General] ericc191:
I keep wi-fi on 24/7 and have most of my apps auto refresh turned off. It can usually make it about 6-7 hours and that's with the screen on at mid to low brightness for 50-75% of the time. I consider that medium life.
[Nexus One General] NexusDro:
For those who have bad battery life and don't mind starting fresh, try wiping the cache and do a factory reset. Avoid reinstalling any 3rd party apps and then monitor the battery drainage rate. If it doesn't improve significantly, then there's probably something wrong with your phone and battery. Reinstall your 3rd party apps and see how much worse the battery life has become. If it is significantly worse then there's probably something wrong with the app setting.

On 2.1, my phone last a whole day (8am to 9pm with 20%+ battery left) with moderate usage (music during my commute, 3G browsing, Gmail, one Exchange account, one IMAP email account (no polling, manual refresh), facebook and twitter set up to poll every 2 hours.)

Haven't tested 2.2 thoroughly yet.
[Nexus One General] ram130:
Had the same problems. After one month or two my battery now lasts 20-30hrs easily with 2hrs of display on time, 10min of music, 1hr worth of calls. Wifi & 3G on. I think yall should give the battery more time to calibrate. Takes time.
[Nexus One General] AndyCr15:
I don't really trust the battery stats when it says this though. This might be just the CPU used for Twitter cost you 2%, but the data usage might have cost you 10% which is not shown in either Cell Stadby or Phone Idle.

Again, we probably differ on what 'hardly use' means. If I've had my screen on for almost 3 hours in a day, that's heavy usage. I'm only awake for 16 hours... that's almost a fifth of my day I'm playing with my device! You seem to be the only one that classes this as 'hardly use'. If I got 20 hours when I used it this much, I'd be really happy!

Right now I've been off charge for 20 hours, screen on time is 22m 4s! That's 'hardly used'! I've received a couple of calls and a few texts and I'm still at 77%. I'm at home on WiFi, when I go to work in a couple of hours and have to switch to 3G it'll start to plummet, but I'm going for a new personal best :) Maybe 30 hours without charge.
[Nexus One General] RogerPodacter:
again, google's official rating for continuous SCREEN ON time is only 6-7 hours from the official specifications page. thats full battery to dead in 6 hours with screen on. if you are using 3 hours of screen on time, then another 24 hours, that is damn good battery life.
[Nexus One General] Mokurex:
I don't need dual core processor in the next generation of phone, I need double the battery life. =)
[Nexus One General] bigmout:
Wait, what? You said you used your phone for 2 hrs and 45 mins. Your stats say that, for most of that time (i.e., 2 hrs and 34 mins) your display was operative. Under those circumstances, it's entirely reasonable to think your display was responsible for most of the power you consumed.
[Nexus One General] wastegate13:
As i type this i am sitting at 57 percent battery life. My phone has been off the charger for 11 hours and 15 minutes. The screen has been on for 1 hour 25 of those minutes. I hope the battery life does improve as some suggest after a few weeks. I may pick up one of those 1600mah batteries to test a difference. If that doesn't help adequately then I'll jump on that 3200mah bad boy.
[Nexus One General] AndyCr15:
Again, that's reasonably heavy use 1h 25m. You're not doing bad to be at 57% still.

I'm on a record setting run for my N1 though, 34 hours since charge and I'm down to 23% now. About 22 hours of this was on WiFi though, around 1.2% per hour then. Now I'm back home on WiFi, I could probably go another 10 hours too.

Of 34 hours, display is 30% of my drain with only 1h 16 minutes of 'Time On'.

I have been underclocked to 800mhz for this, but tbh, I don't think that's made much difference.
[Nexus One General] wastegate13:
As of now i am sitting at 38 percent battery life. Phone has been off the charger for 14 hours and 25 minutes. 2 hours 12 minutes screen time. I've been on wifi since I got home at 2 est.
[Nexus One General] Docmjldds:
Don't waste your time with Seidio 1600. I have better times with stock and I have gone thru all the posts on recalibration, etc. I am an original owner, BTW dating back to mid January, of the N1. Don't remember off hand but there was a site that did a substantial amount of testing and basically proved the stock battery did better, when placed thru exhaustive testing. If you still want the battery, mine is only two weeks old. I'll make you great deal :) (Based on my purchase when they first released the battery) It stays in a drawer now, only for occasional backup if needed.
[Nexus One General] ram130:
Welllllllllllllllll It's been 11h 38min since unplugged and I'm at 22%. 1h 59m 37s of voice calls, 2h 32m 6s of display on time. Wifi has been on for 11h 37m 18s and I have 3G on.

COMPLETELY STOCKED too..:rolleyes::rolleyes:

[Nexus One General] luojs:
I have "Netcount" and "RF Signal Tracker" installed When I am on 2.1. The best record is eat 30% battery in 12 Hours(light usage but Weak 3G signal).

After OTA to 2.2(Then I unintalled "Netcount" change to "Stats"). N1 eat more than 60% battery in 12 Hours ~!@#$%^&*()_+.

First I found "RF Signal Tracker" have some kind of Wake_Lock after exit(Because it prevent N1 from Sleep untill manually kill the process).But The satuation only got a little bit better.

Then I unstalled the "Stats". Now N1 only eat less than 20% Battery in 12 Hours.

I think google was right, the battery life issue most cause by bad apps.

BTW: I have Exchange Push enabled all the time.
[Nexus One General] ram130:
Well I unplugged it at 5am and so far I have done 12min worth of calls and 5min worth of texting. Downloaded 2apps ,one of which I'm currently using(xda). Im at 81% now and its 10:50am. Lets see how today goes. Btw, I lost 5% in 15min of taking it off the charger this morning!!

Out of curiosity... when did everyone get their "F" phones? I got mine first day. There is definitely a quality control issue here because some people (like me) are already down 20% from 7am and haven't even used my phone, as compared to people who go 30h before needing to charge and they beat it up. Also, what about 3G? Are those of you with great battery life in 3G?
