Basically as the title says, I've bought a "refurbished" one, but I'm not sure whether it's faulty, or whether this is just the average battery life of one of these things!
Woke up at 6am, I used it for about 30 mins this morning on facebook/ebay/bbc news through wifi. Send about 20 txt messages, 10 minutes on the phone. ANother 30 mins browsing/facebook on my lunch break. 12 hours later it's sitting at 17 hours battery life. And it's been on power save mode the WHOLE time. Is this just something I'm going to need to get used to or is mine just a dud?
LOVE the phone otherwise though
If you download Better Battery Stats app (either in the play store, or on this site here http://forum.xda-developers.com/showthread.php?t=1179809), and GSam battery monitor you can check up if certain apps are causing your battery to drain.
I had a really bad drain on my battery whilst in standby mode, and these battery apps helped show me that a few rogue apps were preventing my GS3 from going into deep sleep and the battery was draining even with the screen off.
I would say its more than likely an app causing your battery drain rather than a faulty phone. I spent weeks thinking I had a faulty phone then discovered these battery apps to find the problem... my battery lasts very well now. It just takes some patience to find the culprit.
What was your screen on time? Settings >> Battery >> click on screen and it will tell you the screen on time.
When you use GSam battery monitor, pay particular attention to the apps sections 'View time held awake' and 'View num times waking device'

Biggest culprit is usually having facebook sync on in the background, check that in settings. It's an awful app. I use other things like Seesmic to check facebook now.

Hi,
I've been noticing that my Hero has been gulping battery down VERY fast.
In general, the battery lasts 7-8 hrs, which is not acceptable (I'm out for 12+ hrs).
My usage is not heavy. Wifi, Bluetooth and GPS are rarely, if ever, on.
I do read some news and surf the web a little but only for 2-3 of those 7-8 hrs.
Is my battery life normal?
I've been reading people achieving 12+ hours with their stock battery...
2 or 3 hours websurfing is very heavy on the battery, much more so than phone calls. One of the biggest drains is the screen and you having it on for 2 - 3 hours is going to drain the battery I guess
Seems very poor, much poorer than my iDevice that I use more frequently.
Today, after flashing the 2.1 ROM, it has gotten worse.
Battery's down to 40% in 6 hours, and Battery Usage shows 50% phone idle, 50% cell standby.
I've not even touched the phone since unplugging it 6 hours ago ;S
Is it possible I've a defective battery?
If your battery is down to 40% after 6 hours of it being idle (no screen but switched on) then either you have some power hungry app(s) running in the background or the battery is defective.
At the moment my battery is showing 40%. It was last charged about 40 hours ago, and I have had it switched on the whole time with some light use, picking up emails in the background and occassionally switching the screen on.
I ran task killer and sync was off.
One thing I didn't do was charge it for 10-13 hours straight on first charge; I just unplugged it when the led turned green in ~4 hours (impatient...).
Could this have affected battery life?
Nope - when the LED is green it is fully charged. No minimum charge times suggested in the manual.

That is amazing battery life, I never get more than 24 hours with similar use... what ROM and radio are you using Peter? Also, where are you and what network are you on?
I am in UK on Orange, and have standard Orange ROM and Radio - not the latest one but the one they had before 2.73.61.5.
I have read lots of complaints about battery life, but I think mine is fine for a smartphone. I am a relatively light user of a phone - don't do lots of surfing or watching videos. A few phone calls, very few texts, checking emails and listening to some music is all I normally do with it. The other thing I do use it for is I always have the sat nav on while I am driving, but in that case it is plugged into my Brodit mount and charging from the car.
This latest spell may have been helped because I have not been out over those 40 hours - spent the weekend at home, which means that the Hero has been logged into wifi rather than trying to use mobile data. And not used it to make calls or texts or used the music player.
I notice keep Internet connection active take a lot of battery. Go to settings and turn it off and try to see whether the problem exist. It'll will take you a few seconds to re-establish the connecting whenever you need it... not so unbearable considering it'll save a lot of battery.
Same, I notice the mobile chip is using abnormal amounts of battery.
In the morning I watched a 40 minute episode of drama.
Battery dove from 100% to 65%.
To preserve battery life, I turned Airplane mode on.
When I was done with the episode, there was still 55% battery left!
I'm pretty shocked at the battery drain.
I'm using one of the new 2.1 ROMs. They're known for having a bit of a battery-hunger. I solved it by installing the app Ultimatejuice from Market. it's a pay app, but it's worth it. It's also another app called juicedefender (free, less options) that I used before I bought the Ultimate. It also worked good! Now my battery lasts the whole day without any problem
Hmm...well, this is the second time that this has happened in the 2.5 weeks that I've owned this phone. I'm currently running unNamed ROM 1.2.0 and noticed that my battery is draining quicker than usual (8%-10% drain per hour on IDLE).
Usually, my battery drain is between 1% - 2% per hour on unNamed. What I've noticed in both the instances where my battery drains rapidly is that I end up seeing 'Core Apps' (white envelope with android icon in the middle) under the Battery Usage. From what I can recall about this icon, it's the icon for the launcher. CPUSpy shows my phone at 78% deep sleep (the phone's usually around 93% - 95% deep sleep when in idle).
The first time this happened, I was away from home on business for 1 night and ended up having to power my phone off when it got down to 11%. Got home later that day and recharged my battery while the phone was off and after the phone was 100% charged, it lasted 38 hours with 7% left before I powered off and recharged. Again, the battery with light usage lasted 30 hours with 30% left.
Today, after charging (while off - seems to charge better this way) I was surprised to see that my battery was draining at ~10% per hour and I saw that 'Core Apps' was listed under Battery Usage again.
Fortunately, I am not away on business this time (yeah, my spare charger is on the way) so I can recharge teh phone at home. Is the only way to "reset" the phone's battery usage history by pulling the battery or charging the phone?
Hopefully, one of the devs can answer or provide a fix/workaround for the 'Core Apps' drain? (BTW, I leave my WiFi on all the time and my phone still lasts anywhere between 28 hours to 40 hours...just wondering why I have these sporadic glitches when the battery doesn't seem to last long.)
From my experience... this will be very hard to fix. Usually appear ramdomly, and disappear randomly.

Yeah...the 1st time it happened, I was wondering "WTF is 'Core Apps'?"
Now that I've seen this the 2nd time, I'm stumped by it since you're right...it doesn't happen often and doesn't seem to be reproducible by any consistent method.
Hard to do a battery pull with this Neo Hybrid case (case is a PITA to remove) and I don't have my 2ndary charger yet...
Rebooting the phone does nothing since the battery history remains and even powering off for an hour and then powering the phone back on still doesn't clear out the battery history so the drain continues!
Oh well...it is what it is then I guess...I was hoping that someone smarter than I could find a way to cure this. (BetterBatteryStats doesn't show this as a wakelock (partial or full)...CPUSpy just that my deep sleep state is in the mid to upper 70% which isn't the norm.
Oh well, hopefully, this doesn't happen too often.

But a few have reported their phone doesn't behave right in reporting battery percentages after wiping battery stats.
Doesn't mean you can't. But no one has proven it helps.

I haven't had any issues that can't be directly linked to something else (like random reboots).
If all you want to do is reset your battery useage screen to zero it definitely does that. The point isn't to help anything, just to reset the screen to zero without having to wait for the phone to charge all the way.
In that case not a bad idea if you see it show up. If it's as bad of a battery drainer as it seems and still running, it should show up again pretty quick after you clear battery stats.
It'd be useful in reading the logs to know that at a certain time it was for sure running.

Dunno, it's just odd...recharged my phone last night and now I'm back to 1%-2% battery drain on idle and the phone's going back into deep sleep at 93% and I haven't touched any of my settings. I just let the phone dip to 19% and powered off and put it on the charger for ~4 hours (I know, I could've pulled it sooner since it wasn't at 0% but honestly, I forgot.)
It's just the weirdest thing...whenever Core Apps appears as the envelope w/Android icon it seems to be persistent and stays in the battery usage. However, there have been times when the Core Apps appears as teh same icon as 'Contacts' and will disappear on it's own after a while. <-- This seems to be okay as the battery drain remains minimal.
I'll have to check out Entropy's battery drain thread later to see if I can gain any insights. (Haven't ever flashed any of Entropy's kernels as standalones -- I've just been flashing unNamed ROM so I know the kernels are stable builds and not the experimentals.)
Does this look normal to you?
Btw, everyone says that it take forever to charge, but how long exactly? It takes about 3 hours to charge my phone from 50% to 100%. Is it too short, or too long?
I use minimum brightness and running Unnamed 2.1.0
Where did your battery defect to? Those fricken commies.
Overall numbers don't really say a lot. You need to look at what might be causing excessive drain. Do a search for "better battery stats" here on XDA. It's essentally the pay version in the market. That will well you any "offending" programs that might be using up excessive battery time. 22 hrs on a single charge fricken awesome and you show more battery to go.
Yes it takes quite a long time to charge the battery. 3hrs from 50% might be a little long but not that far outside the posted norms. If you're connected to the computer via USB, it will take significantly longer than being plugged into the wall.
Use BBS to hunt wakelocks - you've got some unusually long awake times.
However, 54% drain in 22h with 1h37m of screen on time is not TOO bad.

I am using Unnamed 2.1, I believe it has BLN support. Is it a battery drainer? If so, how do I disable it? i dont see any BLN setting in Setting.
I installed BBS. Here are the screenshots.
Unless you enable BLN using the BLN Control app, it should not drain your battery.
71% deep sleep seems pretty poor, especially 9 hours of awake time with only 1h37m of screen on time.
it looks likely that you've got an app(s) gobbling up some of your battery. But i don't think your battery is defective at all. 22hrs and about half your battery left isn't too bad. You could certainly do some things to make it better, but the battery itself most likely isn't defective.
My DNA battery has gone crazy. Last night the battery was at 66%, I restarted it and the battery went up to 76%. Today, the battery was at 33%, I rebooted it and the battery dropped to 17%. After that I rebooted it again to see if it would go back up and it dropped to 14%. So I did it one last time and that battery then went up to 24%. I dont get it and on top of that my battery life has been terrible recently.
To try to extend it I have installed Lux to manage the screen brightness, I have turned off backup and Google Location Service.
I got Nova Launcher yesterday to see if that helps, I'm using Greenify to close apps and CleanMaster to get rid of junk. I dont use Google Now or have any apps sync/receive notifications besides Messages and Phone. I can't get through the day and I don't use my phone from 7am to 12 in the afternoon.
I have 25 apps installed from Google Play and all the bloatware and useless apps disabled. I use Next Browser instead of Stock/Chrome
Any solutions or suggestions

Maybe just try to do full cycles with the batter to re-calibrate it, charge it up 100%+ and drain it 99%, rinse/repeat a few times.

Ive read that you arent supposed to drain the battery and this phone is unpredictable for when it will turn off from a low battery.
Sometimes it turns off at 8%, sometimes it might turn off at 2%

You're right about draining the battery however we cannot fully drain these batteries. The system shuts the phone down when it hits a certain level, however you can still power the device back on after it does this, thus the battery still has charge and not fully drained.
And yes they can be unpredictable.
Mine will shut down when it gets to about 5 percent but I was using it one time and it went from 8 to 2 in a second and powered itself down. I think they all act weird when they get really low but your issue sounds like the battery is on its last leg.

According to your battery stats, what's draining the battery the most? Also download GSam battery stats to get a more detailed look at the apps and services that are consuming battery.
Maybe your battery is past its prime, but you want to be sure its not an app or service draining things before giving up.
My Droid 3 and 4 are still going strong as long as I charge them fully and then periodically drain them to 10%.
Hey I hope you guys are doing great !
Well i bought this phone like last month and the battery was working fine for the first few days but then its battery started decreasing faster than before while using the same apps as before. The most battery drains while its still in the idle conditions and overnight.
At first it would only loose like 1 or 2 percent over night but now it looses like 1 percent battery every hour it stays idle.
I have attached 2 screenshots below to show what I'm talking about . Both screenshots were taken 1 day apart and as you can see , sometimes the battery works fine but sometimes it drains a lot and its mostly when its idle. Kindly suggest me something if you got anything in mind that what might be the issue here.
Maybe the radio of your phone, that's what's draining mine fast.
And Facebook is a well known battery drainer
If you tap on the graph once, it allows you to find out the battery drain for specific time intervals and their length can be adjusted as well. Please do that and tell us which app or apps are draining the most battery during standby. Btw is your aod on? Aod prevents the device from sleeping properly so the battery drain can rise up to 2% per hour if its on. If that is not the case as well, try turning off location and nfc if they are not being used, and turn off wifi and cellular before going to sleep and then check the drain. Also try disabling google play protect from play store, and check out the link below which improved battery life for many people including myself:
