so yeah,,, i got a nexus one from a friend of mine (whos done alot of flashing and installing custom roms on this phone so i dont really know whats running) but it drains about 10-15% battery every hour or so.
ne suggestions on how i can figure out if its a bad rom or a bad battery??
thanks
Easiest way to know if it's the ROM is to flash a new one. I suggest cyanogen mod it is some what simple but works well and battery is just fine. There is plenty of documentation on the forum to show you how to flash but if you still can't get it just ask and I can walk you through it. You may also want to check settings -> about phone -> battery use to see what uses up the most of your battery.
you could try calibrating the battery
so ive ran some tests, basically fully charge one time without simcard and another time with, to see if the radio drains more battery. and both times its about the same.
i did order a few batteries off ebay, but probably will be like two weeks or so before they come in.
mmmm the md5 stuff kinda confuses me haha, dont know how that stuff works
You don't always need to check md5 you can if you want but most people don't just make a nandroid backup and that way if the file is corrupted you just flash it back and your good. But if you do want to check them just download ManD5 and check to see if the one on the file matches the one on the website.
Under >Settings >About Phone >Battery >Battery Use
What are the top 5 applications and what %?
Wifi should be set to never sleep. under >Settings >Wireless >Advanced >Wifi Sleep Policy
Find out which ROM and radio are being used. Cyanogenmod7.x or OxygenROM would be good for battery life.
You should also try charging the phone to 100% and then wiping battery stats.
Does your phone get warm when charging?
Having swapped ROMs back and forth, wiping everything, I get the same bad battery life (-10%/30 minutes). Wife's N1 runs fine, ours ran the same stock OTA versions until this. I needed to see if it was something related to the OS and tried some alternatives.
Replaced battery - no difference (wiped stats, etc)
Turned off data (wifi and non).
I can't tell when the radio was updated on mine - if it was related to an update that would correlate to the problem, but I have the latest radio that has been out a while.
Logcat looks just fine. It's not data related, nothing seems to be going on when charging...
My hands are cold, using the N1 as a hand warmer right now (it's plugged in)...
There's a bug with CM's kernels causing a LOT of battery drain when you set the wifi sleep policy to anything but "never sleep", check that and change it in case it's not. I know it sounds counter-intituive, but it really works.
I set mine to "never sleep" and easily last a full day on a charge. I also calibrated my battery using the battery calibration app, and using a plain black background helps somewhat if your N1 is AMOLED

So I flashed the new Fresh ROM and it is taking FOREVER to charge. I finally got it up to 100% and less than 7 hours, it was completely dead.
Any ideas?
Me too! Killed my battery in 7 hours while charging overnight!
Have you looked at what's using the battery?
I know in some of the other 2.1 roms, facebook is constantly syncing which kills the battery.
You can use logcat in sdk to see what the phone is doing while it's idle.
Also, service can also change the drain on your battery. I know at work (inside a 3 story brick building) I get horrible service and my phone is dead by noon if it's not plugged in. At home, it can go all day and then some.
Same issues here. Takes forever to charge and dies quickly. I haven't flashed the new radio yet....could this be this issue?
I've been using it since he released it and battery life is more than excellent. I can go a whole day then some
Go under settings, about phone, battery. What is your uptime and awake time?
Then tap on battery use. What has the highest percentage of use time on your battery?
Also check out 'cell standby'. Tap it.. Time Without Signal should be very low, or missing.
up time 8:57
awake time : 2:42
highest use is close between cell stanby48% and phone idle 47%
time without signal : 0%
BTW my battery was at 38% with little use(a few text msgs and fb mobile a couple of times)
TWS is fine then. Do you have the sync icon constantly running?
And what is your PRL/PRI (sorry if you posted that already).
PRI - flipz_01
PRL - 60663
What about the sync icon?
sorry....no sync icon
Weird. Any mods/themes/etc?
What I would do at this point is wipe everything (including ext), and reflash, then see if you still have the problems. I haven't had those issues, so I can't give you anything else to look at.
Perhaps someone else can, but that's all I can think of.
You could try the new radio. Some have said they get much better battery life with it (which is likely caused by the radio not having to search for signal as often...but since your TWS is 0% I'd be surprised if that's it). Try that, then nuke and pave would be my suggestion.
Last night was the first night that I had my alarm set. Could this have anything to do with the drain?
I had a weird issue with the battery. I don't know what exactly caused it and I could not pinpoint it with "Battery Use" nor "Spare Parts." My phone was staying constantly awake though, no matter what.
I eventually just partitioned the SD card, with no ext partitions (no apps2sd), flashed fresh again, and now it's all working great. I am installing my apps very slowly and monitoring them to see which one may have been causing the problem. So far no problems though.

I was getting decent battery life when I flashed 2.0d originally so this might not help you but after I flashed the newest radio my battery life got way better. I can listen to slacker radio for 4 hours while studying and use the phone intermittently throughout the day and get about 12 hours out of the battery life.
anybody who has crappy battery life check if your phone is on GSM auto PRL?

I'm running Fresh Rom and my battery is great. I haven't charged my phone since 6:30am this morning(it's 8:30pm here now) and it's at 60%. I'm using the new radio too.
scratch what I said yesterday, lol... my phone randomly rebooted overnight and now I can't get it to stop being 100% awake...
EDIT: Tried rebooting, tried "power cycling" phone, did the CDMA (Auto PRL) fix just in case, didn't install any new apps, battery use shows TWS at 0%, Cell Standby Time on = My total uptime.
Spare Parts Battery History shows my phone as 100% running, no sleep time.
Spare parts partial wake usage just shows Android System..
Battery is draining like crazy..

That shouldnt be an issue any more. Flipz fixed it in 2.0d.
Change your screen brightness to auto. When I first flashed it was at the highest setting and killing my battery. A lot better now...
Alright so I've been running the cyan nightlies, I just updated to the latest one, installed the battery fix. Everythings working fine, put my phone down for and hour and the batt is at like %75, I go under battery use and it puts the screen at 79%, is this normal? I had my screen off most of the time and when it was on it wasnt bright and if this isn't normal how can I fix it?
Have you rebooted to see if it does this after every reboot? Try rebooting normally then see if its still doing it.
If so, then reboot into recovery, wipe dalvik, then reboot normally. Check your battery stats again after a couple hours and see if it's still doing it after the dalvik wipe.
(FYI, this belongs in Q&A section)
can you link to the battery fix plz?
I have had very high display usage on every version of CM6, and you will find it is a VERY common complaint on CDMA Hero's running CM6.
Everyone says it's because Froyo is more efficient, and uses less battery overall, so your display percentage is higher.
I call B.S. on that. I have had poor battery life with the more than 20 nightly versions I have run. I have had the Hero since the day before it came out, and I have never had worse battery life. I even bought a new battery thinking my battery was dying on me, and I still won't make it through a day (7 am - 11 pm) without plugging the phone in during the day.
My guess is there is something up with the display/lights/light sensor drivers that have been implemented in CM6 that don't allow something with the display to sleep properly. Either that, or the battery usage screen is simply completely inaccurate.
I could literally reboot my phone, leave it untouched with the screen off for four hours, then turn on the screen for one minute, and the display usage would shoot up to 50-75%. There is no way one minute of screen usage is using more battery than 4 hours of phone standby using the radio, checking email/twitter/facebook/gmail.
Anyway, that's just my opinion on the matter. Other than the battery life, the newest nightlies of CM6 are simply incredible, so I just deal with the poor battery life.
@ziggy682 -- Thanks for that info. I haven't yet tried CM6 (mainly cuz I'm so dependent on some Sense apps and widgets), and now that I'm reading about some battery issues I may hold off on trying it even longer.
@omair2005 -- if you haven't found it yet, here's the new thread on collin_ph's battery tweak specifically for CM/darch ROMs: http://forum.xda-developers.com/showthread.php?t=762283
Ok. so iam on darkys rom 9.3, used wipe and ever since my battery life has been bad since.
Take today for example,i pulled my phone off charge at 7isham listend to music for about 45mins, had possibly 3 hours of sporadic internet usage 3g/hsdpa, always turning off the 3g after usage. At about 130pm i had to switch to my 2nd battery.
this is a typical day for me, so its preeeety frustrating.
anyone have any ideas why or similar experiance and can share some wisdom?
cheers!
The first time you use the phone after a flash, the battery will be bad. A couple things to note:
Did you flash with 100% battery? A lot of people say this is necessary.
Did you calibrate it yet? When you do a new flash, use the phone until it is dead. Charge it without turning it on. When the battery is 100%, go into recovery and wipe the battery stats. Then use the phone again until it dies. After that normal charging patterns.
Some people say that they get better battery life with certain kernels, and whether or not you have lagfixes. I use speedmod and I'm getting great battery life.
Check all of these and see if anything helps.
Try this thread as it has a lot of helpful tips.

Clue your rom if you did not have battery drain before .
jje
First think: have you installed any programs that need constant internet connection, like skype or facebook? To check whether this is a possibility check battery history, when cell standby is absurdly high even though the screen was on some time it's a good indicator something is constantly downloading (That only works if you used your phone since unplug, I have 72% for cell standby because I never turned the screen on since I charged it: )
If you ruled that out check whether your modem is appropriate for your region.
After that you should wait and let the phone run down to very low percentage or even let it turn off itself. I don't believe in wiping the battery stats, the battery will calibrate itself with every charging cycle. just let it drop under 10-20% and then charge fully. That helps me.
If the drain does not get better after 2-3days fully charge your phone and reflash the rom with the kernel
I've got the exact same problem with my girlfriends SGS. I got her this phone because it is a bit smaller and lighter than my desire HD, and it supposedly has better battery life....but at the moment I'm not seeing it.
Her phone seems to go at 30-80mAh at sleep, whereas mine will be under 5. She doesn't have any apps that I don't, and I can't figure what is causing the drain based on the running apps.

How do you know if the modem is appropriate for your region? I've been dying to find that answer, searched several places but no luck. How do you pick a modem. I have an international GT-I9000 but live in north america.

On the first link there was a tip to make wifi sleep when the screens off, I did this an noticed a major change in my standby(screen off) battery life, it dropped 1% in like 6 hours rather than like nearly 10% Nisha, which I was noticing before.

I know, I read that post many times, but it's misleading, the country listed for each modem is just where the reporter tested out, not by any means comprehensively listing all the countries in which that modem would work well

I am currently running 5.7.893 rooted and I have been having battery issues lately. The problem is I sit here , 1h 37m off of the charger and the phone is reading 80%. The breakdown looks like this:
Android OS 39%
Maps 12%
Display 11%
WiFi 9%
and a couple other small things.
It seems like my phone is never going into standby and I can't figure out why. I've checked a bunch of things and no luck. If I click the chart at the top of battery info, I see "phone signal" taking a constant drain on the battery.
The only thing I can think of to do is to factory reset the phone and see if that helps.
Any ideas?
I would recommend the Factory Reset. But first, is there a chance it's a battery calibration issue? Have you checked the actual mV reading with an apps such as Spare Parts?
Before you do the reset, make sure the Backup and Restore are checked in the Privacy setting. And then after the reset make sure you check the two options presented about Backup and Restore. These show during the new setup after you enter you gmail info. Also, if not in a 4G area, if possible connect to wifi before you finish the setup as your apps will start downloading automatically. Good luck.
I did try battery calibration first without luck. I just did the factory reset and I'm charging to 100% now. I haven't done the titanium backup restore, because I want to see if installing the apps I use from scratch again will fix it rather than just restoring them.

That's a good idea. Lately I've been letting Google install the apps and then I use Titanium to only restore data to select apps (such as Tapatalk).

Well, now I'm confused. I haven't installed any apps yet after the factory reset. after 2h 50m of just sitting there, it's reporting:
90% still
32% Android OS
20% phone idle
16% display
16% cell standby
10% wifi
looks much better, but does this look right? I would have expected cell standby to be the dominant process.
wifi
Having the exact same problem. Seems to be draining battery at the same rate it was before the update (which was supposed to fix battery drain or so I thought). I'm-a try a little experimenting before doing a factory reset (HATE doing them). Right now, I'm theorizing the built-in Google backup process might be responsible because I've never seen so much drain before and I usually turn Google backup off since I use TiBu but forgot to disable it after the update.
In the meantime, I've prepared myself for the battery issues by purchasing the battery dock and an extra battery for three total. Swapping batteries is better than staying tethered to a wall charger so much.
EDIT 1: Looks like that did nothing. Next, I'll try wiping cache (didn't do this when I updated)
EDIT 2: Looks like not much change from wiping cache. Guess I will be trying that reset.
EDIT 3: Looks like I use the phrase "looks like" too much. However, the factory reset appears to have resolved the issue, at least initially. Fired up the phone and Android OS was only 8% of the battery usage after 10-15 minutes. Will check back if anything changes.
Disable push sync on your device.
changing and controlling your sync settings will solve your standby issues and improve your battery life.

I think a better way of looking it this is that your phone isn't spending 32% of its time using the Android OS and only 20% of its time being idle. That's just how much battery they are using. Your phone could be spending 3 hours "idle" and only 15 minutes using the OS and this is how it could read. It's just how much battery each one is using, not how much time each one is spending doing that particular task.

I'm with noosympathy on that one.
A ROM will improve better life but not that much... maybe if you ran it on 3G only, but then again, that is a maybe.
A lot of your battery is used when your phone is syncing.
When connected to 4G, it uses a lot of power trying to get a signal as well.
To help get some more life out of your battery, disable push syncing and notifications.
I set mine to 1 hour because I don't like being bothered for stupid bs.
When your in a place where you know you don't get 4G, turn it off. It is going to try to aquire a 4g signal while running on 3G the whole time draining your battery.
If am out and don't need 4G, I turn it off. It only takes about 15 seconds to turn it back on and have it link up.
Do you really need to be on 4G to play angry birds?
I recommend installing tasker. You can program stuff like this into it.

Maybe I'm weird, but I don't have a need for 4G data all the time. 95% of the time I leave it turned off and battery life is quite nice with the Bionic just riding on 3G. If I'm in a situation where 4G would be useful I'll manually turn it on. Battery life is so much nicer when the radios in the phone aren't constantly fighting for supremacy.
Call it as you will. I leave data off unless I need it for something and when I do use it I only use 3g. Most of the time I'm in a wifi area so I'll just use wifi. Speaking of wifi I leave that turned off also unless I need to use it then I turn that on for the time being and turn it back off when I'm done with it. Other then that I use my phone mainly for texting, and calling when need be. If I'm home I use the home phone to talk, and when I'm at work, I use my cell strictly for text and if you really need me I'll talk to you by office phone. I also leave gps off. I see no reason to leave it on. I tried to post a pic of battery life yesterday but it would not take for some reason.. Like I said. You can call BS all you like. I know what my phone did for the last 30 hrs. Last night I charged it. Downloaded a few apps, and updated some app and played angry birds for awhile last night before I threw it on the charger. Maybe that charge was a fluke. I dunno, but that charge was honestly what I had. Pretty sad to sign up to a forum, look for good info and also try and help out someone else with this phone and give insight and then be called a liar by other folks. Maybe I just won't post anymore. Hope you all enjoy your phones and ROM's. I'll just tend to myself.
Is it just for me? After a full charge the screen on time is about 2 hours.. Tried cm11 and other custom roms without luck.. When i bought the phone and wasnt on KitKat the screen could pass 4hours. Huge different!
In battery info the only program that drain the battery is the system it self . any tips?
check your rom and kernel, any overclock setting is active.
check battery usage to find what drain your battery.
Mine have 4h30 - 6h screen on (just wifi, without mobile data)

@colors Battery life isn't as good as I think it could have been but at completely stock and with nothing on the phone the phones battery is pretty phenomenal, an idle Z1 will stay on for over a week, infact i've seen some phones with 19 days before now quoted within stamina mode.
Just took a pic of one in my workplace and it's saying just over 19 days, that's not too bad for a phone which is always on and capable of receiving apps via wifi (see picture attached)
I know that 19 days is excessive and no one here is ever going to get anywhere near that or even a week, unless you don't use the phone, the problem most of us face is the apps that we use and their footprint on our phones, affecting battery life and performance.
Take a good look at your apps and what you use and see what you could do without or what could be affecting battery.
A clean install will usually give you great battery if theres nothing on the phone to slow it down, eliminating apps one by one might seem mundane but it's key to great battery life, after a while you'll learn whats bad and whats acceptable.
Using the likes of CM11 could cause even greater battery drain as it's all custom stuff, not to mention that some things within the system aren't working as good as they could be, there is still a lot of work before things are perfect, double tap to wake for example is a feature which could cause massive drain.
Always perform a full wipe and don't restore anything via recovery, leave it as a bare rom until you can verify the ROM you are using is without issue.
Hope this helps
