I installed cm7 last night and the battery stats show phone idle and wifi using like 30-50% while display is low like 5-10‰ I'm using 26.04.03.30
Is this a bad radio??

Don't pay attention to those stats. It's been discussed before; they are inaccurate. It has nothing to do with your radio

I've been running it a while longer now and it seems to use next to no power in standby but goes down way fast in use. Any tips about cm7 and battery?

oh geez, where to start...there's tons of info on prolonging your battery life. you're just gonna have to use the search button for that.
it's no secret that the biggest culprit, when it comes to battery drain, is the screen. personally, i've seen improvements on battery life when i turn the brightness setting down.
i've seen my battery last anywhere between 8 hours (very heavy use i.e. screen on pretty much all day) to 30 hours (very light use, few phone calls, few sms, light online surfing, i.e. screen hardly on). rather than what rom or radio you are using, i think how you use the phone has a bigger impact on battery drain.
also, if you want to prolong the life of your li-ion battery, avoid fully discharging it. li-ion batteries perform better (and longer in the long run) when you avoid full discharges.
I cant tell if it's always been like this. Or if this actually isn't normal because I'm always concern with battery life. Im a very heavy user in the sense my phone will be on and im texting, xda, social apps i.e google +, email check every hr, and twitter.
However, i started feeling like my battery has been draining alot faster when the screen is on. I have no problem with the phone sleeping. I was experience this on Calk rom and now acs ics rom. I literally can look at my battery percentage drop 10% in like a half hour. Is this normal if screen is on the whole time? I've used better battery stats and system panel I can't find anything causing the drain. I see the suspend and events but doesn't that effect the phone sleeping?

Are you on the new modem? Looks like you have weak a signal. EG31 might help a little if your not on it already. I used the full EG31 tar right when it dropped and have been getting great battery life (it may be to early but so far so good)

not sure if its going to work but hoping it does thanks for the response still
turn your display down to under 50% you won't see a difference except outside in daylight and kill this app every time you reboot the phone hit Settings>Applications>Running services then hit DRM content > stop > ok
I get over a day on one charge.

Ok ill try the drm content stop..however my display brightness is already down at like 10%.
Also, kill the Social Hub as well, that drains the battery significantly.
You might try one of several roms available in dev. They address most of the aforementioned issues.

The biggest battery drain reason is the location by wireless network option. Make sure its unchecked. Ever since I did that, my battery life has been awesome. I get to keep my brightness high, Bluetooth on, etc...

All the basics (brightness and all that stuff) on top of the stuff you have running. The darn task killer/manager I see in the icon top left of your screenshot is a HOG on resources check the caching... You can literally **** with these phones for half a day to set it up the right way to conserve. I think wireless is hogging too but I am talking primarily about the first part of your rapid loss, the left part of the graph so to speak.

I purchased an extended battery and was still getting crappy battery life. SpareParts always FC'd on me... but last night I found Badass Battery Monitor in the market and in my opinion it's even better than SpareParts!
It helped me find that the Hotmail app was keeping my phone awake for almost an hour every day even though I had it set to download email only once a day. Removed that right away.
Plus it gives a great % readout in notification of the battery level. I think it's a fairly new app, but it really is worth checking out especially if you're having battery drain problems.
Just killing Social Hub has increased my battery life significantly. I'm at 11 hours now on battery, with 62% left. This is from last night when I unplugged the phone at 100%.

I'm on the Sydnicate Rom there isn't even no social hubb app. He has alot of the mods like noCiq and everything. My phone sleeps well its just when I start using it I can see it basically draining like 10% every half hour. I'm a heavy user I know my phone will drain fast while I'm on it I just would expect it to last 8-10 hours on heavy use.
Right NOW:
I'm at 4 hours 12 mins 22 secs at 37% left.
Display Time is 50% 2 hrs 41 mins 51s (Brightness is set all the way down)
Android OS 10%
So I'm assuming in 2 more hours my phone will die. If this is just normal for a heavy user then I guess I have to deal with it?
I was very disappointed with my Epic Touch when I first got it. I was getting a dead battery in about 6 to 8 hours no matter what I did or did not do.
Calibrating the battery seems to have fixed it.
I'm at 73% battery with 8:32 hours up time and I've made about 12 calls ranging from 2 to 10 minutes.
I've also checked voice mails, emails and other stuff.
I just charged the battery til it was full, plugged and repeated until it stayed at 10%, popped into CWM5 and cleared the battery data and then used Battery Calibration from the market (free) and it's like a got a battery upgrade!
As far as wake lock issues, I've not having any of those. I took my charger off the phone around 3:30am this morning (100% charge) and when I left for work at 6:50am, I had 98% battery still.
When I got to work it was down to 96%, I checked my email on the drive there.
I'm trying this out, wish me luck.
There doesn't seem to be any possible way to charge my battery to 100%, unplug it and not have it immediately drop to 99%.

If those screens are both from the same charge, I see nothing wrong with your phone.
you have 17% left, and you have 2.5 hours of screen on time. So you're on target to get just over 3 hours of on screeen time which is completely in the norm for these phones. AND you're over 12 hours. I don't understand what else you could ask for?
People get all caught up on total charge time, but, to be honest, it's completely IRRELEVENT.
If I dont use my phone I'll get easily over 48 hours out of the phone... Screen on time is what matters. And from a full charge, if I were to use my phone for 4 straight hours without stopping, it would be about dead. When the screen is on, you're using the phone, and the display is the biggest battery suck out there. When I do all the tricks to conserve battery, and I set it up right, I get 4 hours screen on time, which is pretty incredible with these phones.
Now, If you WANT to get better then you have right now, a few things are coming into play.
1) Your signal is weak, this will suck power no matter what more then it should, so get better signal if you want some more time out of your phone.
2) If you installed a new rom, and you didn't calibrate your battery properly, you're losing battery life.
to calibrate properly:
a) download battery callibration app from market
b) charge to 100%
c) unplug battery charger and REPLUG IN and wait for 100%
d) repeat step c a couple times
e) while plugged in hit the calibrate battery button in the app
f) unplug phone and use til dead and recharge
This will yeild you the best battery life.
3) De-Theme. Although I use a theme, every theme I've tested, for one reason or another, drains my battery faster then running the stock phone theme.
4) If you haven't done the basic battery saving things, you should do them to help yourself out. Here's a few I use.
a) Turn off background data, you only need it on to use market
b) Turn off, or set sync for all email and social apps at as long intervals as possible
c) dont use any widgets
d) download watchdog lite so you can see when apps are acting up and using extra battery
e) when you're done using your phone, open task manager, kill all apps, and clear memory
f) always leave the brightness off automatic and as low as possible
g) download SETCPU and run your phone at 800mhz, and undervolt as much as possible (50mv most all phone can take)
h) use black or dark wallpapers, on LED screens back means the pixel is off which uses less battery
G will be your biggest battery save. I've also tried using the SUPERFREEZE thing in the dev section and, besides in sleep mode, I saw no adverse effect. If you wanna kill socialhub, fine, but I dont see any noticable difference on my phone with it off.
If you do all these I promise you'll get better battery life.
Wow, I did a proper calibration today and I'm getting great results already. I've calibrated before but I never had cleared stats in CWM or did the unplug then replug charging thing.
Anyways, I after 12 hours I'm still at 35%! The longest I've ever gone before is 12.5 hours. Screen on time = 1 hour 30 min, but some of that was a battery intensive game (puzzle quest 2). Also i'm running calk's rom, so i'm sure that helped.
Thanks kdoggy, i didn't expect to see results this great.
Those are good tips too Jermzz, thanks!
Hi!
I installed blackout ICS incredible in my DHD. Everything went well but I wanted to calibrate my battery.
So I downloaded Battery Calibration by NeMa from Google play. Before calibration my batterylife was about 12-24h depending on my use.
Now after the calibration my batterylife is about 5h!! And the same usage as I have always had, couple of calls, net surfing and maybe a little of Angry Birds and spotify.
Did I do something wrong or is my battery dead? My DHD is about 2 years old.
According to Google calibrating your battery (erasing your battery stats) doesn't actually do anything, so it shouldn't have made your battery life shorter. You could install BetterBatteryStats from a thread here on XDA to see if something else is eating your battery. Look at alarms and wakelocks.
Ok, thanks. I installed the BBS and I'll tell the alarms and wakelocks here if I don't find anything funny about them...
bananagranola is right.
- hit my thanks button if i helped you -
calibrating your battery basically tells your OS how much batter it has or doesn't have. IF you flash a rom at less than 100% battery, then the max amount of battery your OS thinks it has might be different from how much your phone actually has. Sometimes this can affect battery life.
The other thing is, did you calibrate at 100%, then unplug immediately? If not, that might trick your OS into burning your battery so quickly.
Otherwise, 12hrs to 24 hours is super amazing, I'm a semi heavy user, and I'll only be able to get 12-14 hours of semi serious use (8 hours standby, 2 hours on off usage, some of that at 100% brightness when i'm outside, and lots of music), end of that I have only 32% left. 24 is pretty amazing, I wouldn't be complaining :laugh:
Well when you simply reboot new stats are generated.

Ok, so I have had today the BBS running on the background. I tried one thing in afternoon, I switched of Wifi. Wifi was off about 3h and when I came back to home I switched wifi back to on. I have still 70% battery!! and about 12h without charging.
BBS alarms:
android, wakeups:83 (Is this much?)
com.google.android.gsf, wakeups:56
com.android.settings, wakeups:13
and the rest of them is under 10
BBS Kernel Wakelock:
wlan_rx_wake: 14m18s
PowerManagerService: 10m57s
and rest is under 4mins
BBS Partial Wakelocks:
AudioOut_3: 3min16s
Twitter sync: 1m56s
BBS Other:
Deep Sleep is about 10.5h
Wifi On/running is about 6h
Is there something wrong or is there something that uses too much battery? Could the battery be "damaged" due it's about 2 years old now?
Sorry for stupid questions but I find it very annoying that sometimes battery life is 5h and sometimes it's way more than 12h with same usage.

What you've got looks fine (which makes sense, since you had good battery life this time). Keep BBS installed. If/when battery life starts tanking, take a look at BBS and see if anything else pops up. If you've got more questions then feel free to post again here.
Although you might miss the customizations of the roms, aospX has great and I mean great, battery life.

I've had my Note 3 for a month now, and I noticed that after 90% the battery starts to drain a bit faster.
For example, between 100 and 90%, it takes about 6-8 minutes to drain 1% while doing something simple like using Facebook, reading an article, instant messaging, texting, etc. This is on Wi-Fi.
But as the battery goes lower and lower, it drains faster.. by the time it's in the 30s or 40s, it takes only 3-5 minutes to drain 1% while doing the same general activities. This is also on Wi-Fi. Even idle drain is faster.
By the time it gets to 20%, it's a bit faster... didn't keep track though.
Most of the times I have charged it were like this: full charge -> full drain -> full charge -> full drain.. etc
I have also tried the popular Battery Calibration app. It didn't seem to have any effect.
It is rooted, and I have frozen some bloatware (mostly some Samsung & T-Mobile apps).
I have not tried a factory reset yet.
Is this happening to anyone else? Maybe my battery is defective?
I wouldn't full drain your battery often. Try to keep it above ~20% if you can. Draining it low like that wears out the battery much quicker. Trying not to charge it to 100% helps also but that is harder to do and need a kernel that can support setting max charge.
But yes I noticed that battery does seem to drain a little bit faster after about 90%. Not a big difference though. And you shouldn't sweat it. Battery chips and batteries tend to have different characteristics from phone to phone and battery to battery to battery. Even though it should be an exact science, exact science battery chips cost a lot more. My note2 took forever to get off 100% but once it hit 99% battery drain was very consistent. Less so in note 3 but more or less consistent. Don't sweat it. I would worry more about trying not to drain your battery so low if you can. Your battery will perform best and last much longer if you can keep it between 20-80% but that is OCD. Just let it do its thing. Early android phones were terrible mostly at being accurate and consistent.

Hi guys,
I'm having trouble getting through the day with this phone. I have a new Anker 2200mAh battery that I've cycled about 3 times now. I am running BeanStalk 4.4.4, and I have few tweaks like, Memory Manager (cause it keeps freazing, running out of ram), Entropy Fix app (at ~512, which doesn't seem to fix lag, but not sure), greenify and Amplify, related to battery.
But I'm still draining about 6%/hour on mobile data. This is not normal right? It's really hard to get through the day with this kind of battery life.
So what do you guys do to get about 1% or 2% drain per 1 hour in standby on mobile data? I'm using Xposed, and I greenified apps that greenify says wakelock a lot.
I would really appreciate your help!
Thanks.
BTW, I'm pretty sure it is not normal because in Amazon website, this anker battery has full of satisfied reviews saying it lasts a full day/ 2 days with this battery, but for me, even with this larger battery, it drains very quickly in standby.
In addition, when screen is on, I get about 1%/2.5 minutes in mobile data at 50% brightness. I think this is fine. Am I right? For 100% drain, this leads to 250minutes, which is slightly over 4 hours screen on time. This is on mobile data, so I think it's pretty good, but I'm not 100% sure.
But because standby drains quite a lot, I'm not even able to get over 2 hours screen on time.
I don't have wifi at work btw.
I hope someone helps me soon. Thanks!
