Does my battery suck or what?

I reset my battery stats 2 days ago after doing a full charge and drain and full charge again my battery is at 94% after 1 hour. My time without signal is only 3%, phone idle is 42%, and only 15 minutes without sleeping. Does this sound normal or am I being anal?

That kind of sounds like mine. Extrapolating the percentage loss over time for me almost always yields a rate of about 100%/24 hours discharge, +/- 3 hours depending on use. I've always been concerned about the battery, especially after hearing so many people saying they get almost 48 hours on a single charge with moderate/heavy use
My battery is new. My Hero is less than a month old, but I haven't put on a custom ROM yet. I think a custom ROM and kernel is supposed to help. Mine is rooted and running SetCPU with profiles. I found that whenever my phone felt hot (which is a lot of the time, actually), it's usually an indication that battery is draining fast. I also read many peoples' Hero's run very cool, and don't get that warm when charging. Mine can get pretty warm when charging, close to 40C, and 42-43C when using while charging. These observations have caused me to wonder if my battery is bad, or if newer Heros are somehow different from old ones. Does this sound like yours?

I've learned that the battery usage is not linear.
So dont' worry about 1 hr sampling of your battery, use a minimum of 4-6 hrs and if it still losing 5%/hour after that w/out much use, then you may have an issue, but I wouldn't worry about it.

I'm using Crunchy's buufed rom with the OC'd kernel. My temp stays pretty even but I did add auto memory manager yesterday. I wonder if that's contributing.

I just figured it out. The stock sms is still locking up the dialer and keeping the phone awake. I figured that was fixed in these custom roms. So I disabled all notifications on stock sms and downloaded handcent. All is well.

I believe your aren't supposed to use things like autokiller and auto memory manager with an Oc'd rom.

I agree on the task manager but I thought the memory manager would tweak the built in settings from conservative to aggressive. Am I wrong?
Sent From My Hero!

It still does that but I've read posts by devs saying not to use autokiller with and overclocked rom, I don't understand why either but that's what it said.

Thanks for the heads up!

Battery Drain Drach 2.7

I have done every possible thing i could think of to stop my battery drain:
first i had automatic task killer installed but it seemed as though that may be causing the drain
then i installed UV kernel and uninstalled automatic task killer and i thought it was getting better but it is now doing the exact same thing as before... about 1% every 5 minutes...without much use
i have the latest radio baseband (2.42.01.04.27) installed, but my battery stats are:
cell standby: 49%
phone idle: 43%
display: 10%
health: good
now i switched back to using automatic task killer WITH the UV Kernel but it doesnt look promising as my battery was going 2% every 5 minutes.
I tried to use setCPU but got a little confused setting things up so if that helps could someone please help me with that?
Thanks in advance for any help i get...
-Brian-

This is exactly my situation. I've been looking for a couple days for a solution, as I've been seeing people getting over a day with no CPU manager, no ATK or anything of that nature. Have you actually seen a difference with Task Killer on?
Now I'm just curious what could possibly be running?

yeah with the task killer running it seems to die slightly quicker... at least with UV kernel... prior to UV kernel the ATK actually helped a slight bit. My battery life just gets worse and worse... yesterday i was using wireless tether and it actaully LOST battery while charging because it was so hot. i have no idea what could be killing it.

Shame, I guess if I can't get this solved I'll have to go back to a non-OC Fresh build. Don't get me wrong, I really like FreshROM but I like the AOSPs so much better. I'm thinking my phone just doesn't like to be OC'd and I don't know if I can do with 10 hours worth of battery with minimal usage.

there were 2 thread about this already http://forum.xda-developers.com/showthread.php?t=704155&highlight=battery+darchdroid
http://forum.xda-developers.com/showthread.php?t=711462&highlight=battery+darchdroid

yes there are multiple threads and EVERY thread leads to the same response
"try reflashing your battery stats"
people have tried that and i still getting IDLE and standby at the same number
I know I am. I have tried all the different suggestions. I'm going to try using handcent again and getting away from the stock messenger to see if that is what is making my phone stay on.

it isnt, ive used handcent and chompSMS and i still get the same results with both.

Simple solution, use a different rom.

buncha wise guys in q and a. seriously though, why?
Sent from my Hero CDMA using Tapatalk

A simple response, yes, but Darchdroid is by a large margin my favorite ROM and I'd really like to use it. Especially considering the fact that DarchROM will be the first 2.2 rom out, it'd be nice to find the source of the problem now.
I'm back to Fresh2.3.3 (non OC) and my battery life appears to be great again. I'm almost curious enough to find a non OC kernel I can use with Darchdroid so I can have acceptable battery life and the UI I'd like.

Need Help w/ Battery (Yes, I've done my research as best I could)

Ok, so ever since I upgraded to CM6 (which I LOVE) I've had serious battery issues and I've tried to fix it by installing Pershoot's kernel and I have SetCPU to underclock in depending on what battery life it's at. Also, I've wiped my battery stats and I've calibrated my battery already.
Today my battery was at 64% after only 3hr and 26min. I don't have GPS on, auto backlight is on, 3g/2g and sync are on. If it makes any difference I have the Korean radio installed (which btw improved my reception a lot! ). After about 9hrs and half, my nexus one died. As per usage, I wouldn't say it's much at all because I'm in class most of the time and I've only talked on the phone for about 1 min, browsed a few websites, and sent only a few texts.
I keep reading on the forums about how people are getting 1-2% lower per hour while on standby but the % I reported earlier, my battery's draining at over 9%/hr!
I really just want to be one of those people that can say that "I still have 50% left after 12 hours!" lol
So, is there anything else I can to increase battery life? Is my battery just crap? Any recommended setCPU profiles?
If you're one of the users that get really good battery life from your Nexus One, please tell me what you did to get it that high! Thanks!

Don't use setCPU to manage battery life, only to overclock. It overrides the kernel's settings. Sounds like you need to wipe and flash the rom again. Then gradually add applications you want, something is sucking battery life.
Last, buy a new battery.

CM6 has less than stellar battery life. If you check the "help with my battery life" type threads, you will see most of the OP's have CM6 as their ROM. Try another ROM, you will get better results.

Quoted for lies

I'm using CM6 and I get between 22-32 hours on a single charge. I just use the kernel that comes with it and i almost always have sync on. No GPS or bluetooth though.
Are you using a battery you purchased on ebay? Or are you using the stock battery? ebay batteries last me about 9-12 hours and die. The stock battery is amazing

Exactly the same situation as you:
CM6.
N1.
Student.
Experiences massive drainage in short amounts of time with low usage.
Tried everything.
I'll now be trying Enomther, because yes I have heard CM6 users get worse battery life.
Just a viewpoint on what I'm facing. For the past week I've gone to bed with 100% battery and woken up ~7 hours later on 75%. I've tried WCDMA and GSM auto settings and neither male a difference.

Thanks, I'm glad I'm not the only one with this problem. I thought I was being an idiot by doing something wrong...
I've calibrated my battery several times already while trying to fix this issue. Could that have killed my battery life?

1) Discharging the battery below 10-15% is bad for the battery, doing it many time will destroy the battery, making it last just about nothing.
2) Check CPU usage - download System Monitor or some other app like that, and check the running frequency of the phone. When you just run the program and don't touch the phone, it should float around 300 MHz. If you have it locked on 998MHz - you have an app that got your CPU stuck in a loop.
3) Download some app that stores battery stats, and check your discharge current and battery capacity - that way you'll know if it's your battery dead or your apps drawing the juice.

Sorry, double post.

crap, all the guides that i've read regarding calibration told me to discharge it completely.
My CPU usage seemed normal. It was stable at around 245 and would jump up to 998 from time to time that doesn't last for more than half a second though.
My battery seems to be in good condition as it's labeled as "healthy" by my battery apps and the voltage seemed normal....

Do a nandroid back-up of CM6, and then try out the above ROM. You can always go right back to CM at any time.

For calibration, complete discharge is necessary. Doing it once is not too harmful. As long as the battery is reported "healthy" - you're ok.
There are apps that will show you the approximate capacity of your battery in numbers. Try to find one like that.
Please check discharge current and voltage over time. It doesn't make sense that a phone on 245 MHz in sleep mode will draw the current required to discharge 10%/hour.

in same boat as OP
im in the same position as the OP
student.
dont use phone for nearly 7 hrs a day
backlight on lowest, gps and bluetooth off.
ive been looking around for answers (hence why im reading this)
when class gets out ive gone from 100% to nearly 65%
running cm6 and ive wiped battery,
about to switch ROM, maybe that'll help.

Awesome, if you find a fix let me know please.

I haven't been able to do any of the suggestions yet but (when it comes to flashing) but I do have an update that might shine more light on this issue.
Today in class I noticed that my N1 was warm when it was in my pocket but nothing was running and gps and bluetooth was off. I checked the temp of my battery it was at 36.1C while it's usually at 30-31C when I'm not doing anything.
Also, I checked spare parts this morning and found that, while I was asleep, my N1 was not asleep for half that time but my screen on for only 4% of that time (probably from my messing with it before and a little bit after sleep).
I've checked to see if anything is running in the background that might lead to this but so far none of my apps should drain my battery that much while I was asleep.
Is this normal? Shouldn't my phone be mostly in sleep mode when I'm asleep since I'm not doing anything to it? As for the battery heating up, do y'all think it's a faulty battery or the fault of the OS?
Thanks again for all of y'all's helpful replies!

About battery heating...
I checked and mine is at 75-78F while in class. My n1 is also in a case, so for it to be that low is good. Just thought to throw that in as a comparison.
Also i've switched ROMs to help with battery, no luck there. Still experience 7-8% drop per hour.
I've been keeping my phone off now at school, which has helped, though I still lose nearly 15% while it's off.

[Q] My Battery is suicidal please help.:)

ok so i own the sprint htc hero obviously and i keep switching between plain cm6 and blackmod every few months or so. For my Kernel i use
Decad3nce-DecaFuct #589 691mhz CFS stable
i keep it clocked at 245-691 with collins battery tweak
i charge my phone to 100% and then unplug it. screen off, gps, mobile data, sync, bluetooth, 3g, everything is off. brightness is as low as it can go. so im doing everything i can to save battery power. if i leave it in my pocket all day it CAN last about8 hours....that being said at that point its basically a brick. however if i turn anything on obviously it dies faster. if im online for 45 min my phone will die. a five minute youtube video costs me 32% of my battery. there is no way that my phone should be acting this way and im out of ideas. i have tried switching roms, wiping battery stats, running through battery cycles reverting back to stock via the RUU nothing works.
PLease if you wonderful people have any ideas *PLEASE* help me with this.....

Well you could try running a more current rom like CM7 or Aosp's CM7 GingerBread. Also you could try running your roms without the Collins battery tweak. You could try using dec's battery tweak if you prefer to use one. You could try calibrating your battery. Just a few things you could try that might help.
Edit: Also do you have an on screen off screen profile set with the battery tweak???
Yea its me Again With the

i have tried cm7 and still had the same issue. and i am partial to the battery tweaks because setcpu and ocwidget seem like they would eat up resources wouldnt they?....i dont think ive heard of decs battery tweak tho....unless you mean the DECAmod one and i thought that was only for 2.1 roms.....maybe i got my facts mixed up tho...i calibrate my battery everytime that i flash a new rom to the phone. as far as i know the version i have does not allow for seperate profiles for screen on screen off.

I had the same problem and out of curiosity i dropped my processor speed from 710 to 576. Yeah its slower but on Aosp/CM7 and with sd-ext done its plenty fast. and with everything on and the phone in my pocket i drop about 4% every hour.

Deca's BattMod will work on CM7/aospCM7. However with CM7 you really don't need it (or anything else to overclock/underclock) as CPU settings are in the ROM itself. In fact, it is recommended that you don't, as they will/could fight with each other.
If properly calibrating the battery (properly is the key word) doesn't get you at least a solid day with moderate use, I would say it's time to look for a new battery. How old is it? Mine is about two years old and I still get about 2 days, stock aospCM7 ROM and kernel, moderate use with ONDEMAND 176/729

I'd still say that 4% an hour, without using the phone is way too much. If your battery is still good, you should be able to get better than that by at least half (2% an hour drop).
I have been up for two hours (unplugged at 6AM, it's now 8:56AM) and am still at 99% and that is with moderate usage (a couple texts, sent and received an email, one 3 minute phone call, some Facebook and XDA).
See ^^ for my settings. Give it a try

My brothers hero would die incredibly fast also no matter what we tried. We ended up RUUing and taking it into sprint. They did a battery test said they didn't know why it died so fast and ordered him a brand new one. He had normal batt life again after that.
So if all else fails try taking it into sprint and see what they tell you.

When you go to the battery usage stats in Settings--About Phone, what does it show you? That may show/tell what is eating up your battery so much.
What is your signal like? Are you in an area with poor signal? If so that could possibly cause the battery drain -- a phone working hard to keep a decent signal eats battery pretty quickly. Consider upgrading to the newest .29 radio baseband (if you're on Sprint) if you haven't already.
Try to check out the battery usage in your Settings and report back what it shows. We may can help you notice anything out of the norm.

my phone is about 7 months old. so battery *shouldnt* be crapping out quite yet as battery life on one of these seems to typically be about two years before it starts to crappify.

@MrDowntown12
i thought about that but was worried that the ruu doesnt get it COMPLETELY back to stock. good to know it does and that someone pulled one over on sprint ^_^ if all else fails then ill try this but in all honesty they will prob still charge me $50 and i just dont have it.....
@chromiumleaf
battery usage is:
Display 59%
cell standby 12%
Phone idle 11%
android OS 8%
Media 5%
setcpu 3%
google search 2%
gallery 3d 2%
"top -m 5 -n 1" returns
process id 2337 at 8% and 163 which i believe is the phone itself if im not mistaken is at 5%......everything else is zeros.
also i think my coverage is pretty average. throughout the day i typically have about three bars but my dbm is 80-100 the whole day and im not sure if thats high.
fyi these stats are while doing my battery cycles if it matters. and ive been unplugged for about 25 min and ive dropped from 100 to 91 with doing nothing but checking battery stats and running the terminal for a minute.
Edit: i know that android os is getting more and more popular....do you think its possible that i caught some kind of virus somehow???? the only ones ive seen are in china but is it likely that my phone is infected? also i want to run cm7 but as far as i can tell there really arent any stables out yet just the experimental nightlies and ive tried it and it didnt fix drain *immediately* but maybe after batt cycles? second edit^_^ i apologize i did not know exactly what you meant by signal. after finding THIS
-105 to -100 = Really bad
-99 to -90 = Not great
-89 to -80 = Pretty good
-79 to -65 = Good
Over -65 = Excellent
i now understand and my dbm hovers at about 88 half the time and the other half it shoots to 97

Ok so if all you were doing in 25 mins was checking battery stats and running the terminal for a little bit, it seems strange that Google Search, Gallery 3d, and Media would have some battery pull on them -- did you even open/use them at all? If not, then it seems like maybe you have some programs running non-stop in the background that are eating your battery even when you're not using them. Try clearing data and cache for any of those in your Settings-->Applications-->Manage Applications menu.
Also, just curious...when you change roms, do you wipe everything (data, dalvik, ext) before flashing to a new one?

I forgot to say that i have music playing through headphones whenever im awake lol, but yeah ill give that a try.

No I had not used any of those. I tried what you suggested and the battery is draining faster T^T. And I always do a full wipe. I wipe data and dalvik reformat my sd and as soon as I her the rom on my phone I go through three battery cycles.

HAHA Solved! for me anyway.
ok so my guess is that its not reading my batts full capacity because i didnt charge fully before one of my flashes. so what i did was:
*charge to full
*run my ruu to revert back to stock
*with phone -ON- charge til green
*power -OFF-
*charge for another two hours
*boot into recovery
*flash like you normally would
*Run through your Battery cycles like normal
since i have done that my battery has been fine. or as good as a battery on a smartphone can be anyway lol

[Q] Battery health

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?

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.

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
