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.

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
Hello all,
I just received my new battery from obostore.com. I have cleared battery stats but it seems to be charging and discharging at the same level as my previous stock battery. Could it be that I am doing something wrong?
Battery calibration takes a few cycles to accurately read your new battery.. give it 3-4 cycles and see from there.
An alternative way than clearing from cwm is to use an app called battery calibration.
Cheers.
Thanks. Yeah I have used the battery calibration app. I haven't done one cycle yet and I'm just testing to see how much battery power it's giving me. I really hope it's more than double the stock battery, else I fear I would have gotten ripped off.

double the stock ? no for sure (from personal experience); just make sure u charge the battery 30 minutes after u see the "full battery notification".
deleting the batterystats file is pointless also all the app related since del the file dosent help.

All right. Well is it me or does the battery not last that long. I was expecting 2 days for it to last. It lasts so far a little bit more than 24 hours. Or do I have to let it go through more cycles of charging?

Well.. i do still believe that new batteries require a few cycles before it performs at full potential..
But for the 3500mah will last twice as much as original.. unless the fat battery itself is original made by LG or a trusted brand.. I will take the capacity label with a pinch of salt.
-full charge
-calibrate
-full discharge, untill phone cant be turned on
-full charge back w/o break, preffered overnite aftr shutting down phone
-use it normal
-after your 3rd-4th charge(not including above procedure's charging cycles) aftr this you should notice improvement
During these whole procedure dont wipe data/ dont install new rom.
Evenif you cant notice difference then ask for refund if possible.

Thanks. I am noticing some improvements right now yes. There are some apps which eat a lot of battery. Aside from apps, 3G tends to eat a lot of battery too. I think Skype also uses a lot of battery, to which I had to sign out. I'm on my 2nd or 3rd charge cycle and on this one, I am going to use it as normally as I can.
ok, i've had my phone for about 6 months now....
was on GB Rooted for a few months, then upgraded to the new ICS stock a few days ago, and have now gone back to GB... i'm sticking with stock stuff now, no rooting, no CWM, etc....
but each day i use this phone, it is so unpredictable. the battery life i mean....
i have worked out, that to get the best battery life, after each charge, i need to switch off phone and pull out the battery for 10 seconds...
if i dont do this, battery life is pretty miserable.... this has been going on for nearly 6 months..
eg - if i just charge my phone and use it, each hour, around 3-5% battery life drain. however if i charge my phone and pull out battery and reset phone, battery life drain is about 1% every 2-3 hours....
WHY? why do i have to baby sit my phone?!??!?!? i dont want to always find the best kernel etc anymore.. i think Samsung need to get their act together and fix this damn phone.... i love this phone, but also hate it so much because i have to always find the right rom, kernel to make it usable!
for example, i upgraded to ICS LPY when it came out - OMFG the lag was ridiculous! battery drain was bad, and it crashed my phone all the time... hence i have reverted back to GB...
where is the quality control from samsung?
am i the only one who thinks this? anyone have battery problems like mine?
That doesn't sound like normal behavior... Might be a rogue app screwing up your battery life/stability. Have you tried starting from a clean slate?

clean slate - meaning full wipe?
i've only done factory resets, is that the same thing?
Hi, I would like to know the best way to measure my battery health. For about a month my battery starts to drain fast. I know my phone is already old and battery don't handle the same charge, but I have recharged the phone all night long and in ten minutes using wifi to just update some apps the battery just gone.
It is just ridiculous as I don't use any different configuration.
To be more specific, my phone configurations are:
- Cyanogenmod 7.2 by vo-1 (31/06/2012) deodexed by me;
- Firekernel Unnoficial OC (22/07/2012), CPU governor: smartassv2, max 787, min 245;
- Adrenaline Engine 4.2b;
One more thing. I was facing the same problem with blackhawk kernel.
I just think a battery can't die a sudden.
Could anyone help me with this?

There are a few things that can be causing this, but the first thing that you can try is to wipe your battery stats using "BatteryCalibration" app. After flashing a few things, it's best to do this. I had the same thing happen after flashing my third ROM or so.
After that, it basically comes down to the apps and widgets that you have running. Shut them off with a task manager so they don't end up draining your battery, but it might not be that either....
The only other thing that I can think of is that I heard in another thread (I really wish that I could find it again ) that the ace has a motherboard fault that causes it to drain faster than usual.
Other than that, all I can say is that the Ace generally has poor battery life, and it really does suck, but I don't really know how much more you can do. You could try flashing a stock-light ROM and see if it does the same thing (wipe battery stats too). But I would say is that you should try wiping the stats and see if anything changes.... Other than that.... I`m out. Hopefully it helps, and if it doesn`t, you might need to take it in (Service Center or wherever you bought the phone).
Maybe try searching in other threads (as it is a common problem) but besides that, goodluck :fingers-crossed:

I forgot to mention but I already did the calibration, using the app and manually to see if I could get different results.
I even tried to force a better charge, charging the phone off, waiting till 100%, unplugging and recharging, till the phone gets 100% again.
Ace's battery isn't good, but a month ago my phone was holding 12-14 hours without charge, using wifi a lot, that's why I think something is wrong.
Well, I'm flashing the original stock rom to see if get some change.
Thanks about the motherboard information, this is new for me :good:
Gonna see tomorrow if the battery holds better with the original stock ROM.
Thanks again!
Wiping the battery stats is a myth. All it does it clear the battery usage screen!
Android has a built in tool which can try to check the health of your battery.
Open the dialer
type *#*#4636#*#*
then go to battery information
Look at battery health.
Feedback
Just to give a feedback, my battery was really damaged. I bought a new one, stock because I didn't find other, and the phone now easily last a day, even using wifi a lot.
But that's not the only reason why I posting here again, I want to share how my old battery is. Comparing with new one, I realized that the old battery had stuffed something about 5 mm
If you pay attention, you'll see the small deformation.
Don't know yet what could have cause this, but I think it was heat and bad recharges...
Thanks for the help :good:

I'd recommend you to use SetCPU to prevent this on your new battery. Set up a profile with sound notification when it hits around 40degree, and underclock it at the same time.
I faced a similar problem. Battery was hardly six months old when it died but it was my fault. I was running a wi-fi tether and continuously charging it for about two days. :silly:
Got a new one under warranty. Been a year with the new battery and just recently facing problems with it. 3G just sucks the life out of it.
OK I just got 3g on my phone (yay for promotional 6gb plans!). But yeah, the 3g definitely kills my battery. I used to be able to go two or three days with very little use. Now I can only go one day even with standby with my 3g enabled. As long as I can put my phone on to charge before it dies, its all good to me
Finally with my 3g going, I understand everyone else's pain with the battery life haha

So got my father a S6 and its running stock Marshmallow, Long story short his battery life dies extremely fast. He has wifi turned off and bluetooth on most of the time. He has the phone on his pocket or on a desk not being used and the phone goes from full to 20% in a few hours. Should I flash a rom to help the battery performance or do you think its a faulty battery?
I Would provide screenshots but I dont have the phone on my at the moment.

Was the marshmallow just flashed if so might need to let the battery and kernel set in some scenes screenshots or stats would help determine if its a faulty battery

I ended up flashing back to factory using samsung smart switch, gonna give it another test tomorrow with minimal apps installed and if it drains then i know its a bad battery.
try wiping cache or factory reset in stock recovery. my phone had minor bugs after I installed 6.0 using Odin. factory reset fixed them.

ill try doing that thanks!
My battery life has actually improved since the update.
Make sure NFC is turned off as well (unless you use it often)
My battery life on MM isn't all that bad.. It gave me my first report on the apps that use the most juice, and gave me the option not to have it run in the background.. Not a bad feature.. Mine is rooted with a ton of Apps Frozen or Removed via Titanium Backup.. Battery life isn't better, but over time the device will get to know your habits and battery life should get better over time..
I'm stock MM and rooted running DS Battery Saver with the slumber profile. I'm just settling into it (a day or so) as well but out of the gate it's not too bad (12+ hours per charge). I've got most of the Tmobile and Samsung apps frozen but run a good dose of others.
I'm inclined to think this will improve over the next couple/few days and even more so with a custom kernel.
Update:
So I flashed the phone with samsung smart switch and battery is much better
Not as good as other phones ive used but its much better than what it used to be.

Root it an install deep sleep battery saver if that is an option.
If not, you can install an app like Greenify or Macrodroid and use them to disable sync or data/wifi when the screen is off.
That will help conserve battery quite a bit.
yes thats my next step. Its my fathers phone not mines. Just got my G5 today
