Hello;
I've been an owner for galaxy ace 2 for 4 months now. My battery would last me 5 days until reaching 40%, then I would recharge fully without letting it go under 40% any time. My problem now is since 2 weeks my battery is only lasting me for 2 days (reaching 40%), the phone is still on stock and no applications were downloaded. I am just using it for frequent phone calls and maybe 5 minutes wifi for the whole day using "what's up". So what do you think going on?, I tried shutting off the phone and removing the battery, but that didn't help.
Thanks in advance for your help.
Regards.
5days is a dream me for example have to recharge battery every evening and many others too i think it's not that big problem just recharge evey ssncond day over night and no problems

Why does everyone still complain about battery life?
Every battery is different and how much it lasts depends on how you use the phone. Nowadays you shouldn't expect more than 24 full hours of usage from 1500mAh batteries, even on lower power-hungry devices like ours (not really, dual core).
It all depends on how you use the phone and how you recharge it: remember that Li-Ion batteries lower their capacity if discharged really deep and prefer being recharged frequently.
Very often, battery drain are caused by wakelock or triggers.
I'm using wakelock detector and cpu spy to diagnose.
With Cpu Spy you can see if your phone is realy going to deep sleep.
With Wakelock detector (or better battery stats) you can see what app is causing wakelock (preventing going to deep sleep) or triggers (events that wake up the phone to often).
Big consumers are some widgets, facebook app, Google Hangout, Google Now... some parameters in google maps...
Even if you don't install something new, you can received an update on something old, update that change the behavior of an app...
EDIT: 5 days ! a dream for me. Two days and I'm happy
Dude if i use my ace 2 for just browsing the internet 4 hours and my battery would reach 30% and i find that very reasonable.
And i read somewhere that not letting the battery discharge to at least 20% will make the battery forget its full capacity. And yes Batteries have a memory too.

NiMH and NiCd batteries suffer from the so called memory effect. Li-Ion and LiPo cells lose capacity if you deep-discharge them.

My ace 2 lasts a day of full use (wifi on, max brightness, occasional games, using facebook) and I just charge it when i get home. I never charge through the night, that would destroy the battery life completely.
Why should charging throw night destroy battery life ?

You possibly have some apps runing in background

I think it's a normal things because battery has its own 'life'

Battery life is very good compared to the previous releases. I ran for forty minutes with Bluetooth turned on while listening to tune in radio and using endomondo app. Google now turned on. I lost fifteen percent compared to losing 35% with similar usage. Very satisfied.
What do you think?

Bit unnecessary. To answer the question it's too early for me to thoroughly test battery life.

Ditto. My phone ran like a champ on a freshly flashed ROM. Then my phone realized it was born as a Verizon-Nexus mutt and had a psychological breakdown to the point of 1.75 hours of on-screen time the day after.
Twas a sad day
I'm reading my work email over the exchange service account. After upgrde to 4.2 the exchange service process eats my whole battery so I can't tell about any improvement.

When it comes to battery life (in general, though especially true with this newest release), it's crazy how many divergent opinions you get. Some people claim to get amazing battery life (exactly what quantifies for amazing?) and some people claim the battery life is crap. This is just to remind you that unless you have a good way of measuring battery life, your measurements can be plus/minus hour(s). Someone who just leaves their phone on a black screen with no wi-fi and cell may get 10 hours of screen-on time. Someone who is watching videos with cell/wi-fi might only get 2 hours of screen-on time.
In the future, I can make two recommendations:
Always report a complete cycle (from 100% to close to 0%). This is because the battery does not discharge at a constant rate.
Always report screen on time
Average for GNexus in previous builds was 2-4 hours. I've no idea about the plus/minus, but they tend not to be under 2 and over 4 with moderate usage. I think an average of 3-3.5 hours is what most people are happy to report.
And that is really sad because my old atrix used to get over 8 hours on Wi-Fi with over twelve hours of standby time. I wish they would make this phone but with a smaller screen size. The technology used on this phone is not battery efficient at all.

This tells us nothing....u don't show ur screen on time and uve been charging off and on..
Battery life in sleep mode is worse for me. I am losing 3% an hour with the screen off, I used to lose only 3% total overnight with the screen off not per hour. I tested this over the last 4 hours only waking the tablet up long enough to check the battery level and it has gone down by 3% each time. Nothing has changed with any apps or setting since I upgraded from 4.1.2 to 4.2. I got concerned when I noticed this morning that my battery was over 15% less then when I went to sleep. Anyone else notice this?
This is very good battery by my standards.

yeah using the 4.2 factory image with trinity a4 and getting great battery life
I can only use my phone for around 5hours on time until she dies. This is super annoying because of school it dies before lunch :/. Have flashed many different ROMs, tried different radios, one or two ROMs seemed to fix this but don't remember which ones did . Phone dies 1% every 3 minutes it feels, this is retarded is there any known issues with that or fixes? Sticking with juice defender till I find a better option

do you leave your mobile data on?
also what is your cpu settings?
what rom and kernel you running
and take screenshot of battery usage page and post please
I always leave data on, yes. ROM: Jedi jelly 4, I believe that its insecure kernel because idk any other tw jb kernels. Also on the lb7 blaze radio but I constantly switch those up when I get frustrated with battery. Screenshot may not be accurate because I just flashed at like 430 today, so battery was at like 78% ish on last charge which was around an hour and a half ago. CPU settings are untouched atm

Read my reply to the post here. It's an optional and known way of saving battery life for almost any Android phone and help prevent any overheating that you may experience with the phone.
Is your GPS on all the time? Account sync? Settings and data backup? Auto brightness or manual?
Always let the phone drain to 10% or less then fully charge it uninterruped, meaning dont unplug it.
CPU management always helps, especially with screen off. Also use wifi instead of data if avail at school or anywhere else for that matter

I'm betting its the battery. Place it on a flat surface. If it doesn't lay flat and it has a bulge that causes it to bounce around, your batteries screwed.

Got gsam, have ran it for a day. 100% at 6:00 am, 31% at 3:57 pm. This normal ? I flashed back to stock koodo everything , so is this just the quality of the phone? Yes, GPS is always on. Data is normally left on, although I do turn off WiFi from time to time. I used to have a nexus s and the battery would last for days, yet it's smaller and I never had to turn off things. I even get battery drain like this on cm based ROMs ?!

I went from Jedi Knight 6 to Jedi Jelly 4 two days ago and the Rom is super fast and snappy. Very little lag and no issues with fc so far. I do have a little bit of a battery issue myself. When I use the phone for anything I can sit there for an hour and watch the phone dip to below 80% after a full charge. It seems to eat battery when in use but overnight I get almost 14 hours of left untouched. I would like to get at least 8 hours with medium to heavy use. Is that a reasonable number? I have gone through three battery cycles so far.

Actually we are already discussing battery drain in this thread, so the previous poster did exactly what he should have. We don't want multiple threads for one topic.
Regarding your stats.. That's not too bad, but it's hard to say without seeing screen time, app usage, etc.

For anyone requesting input on battery life, please post screenshots of your battery screens as well as screen time. Also post a screenshot of the app sucker list in GSam battery monitor. It's impossible to say what's going on without seeing anything that's using your battery.

Hello All,
I just received the DMA6 update from Samsung... I know this update is new but it would be good if all of you can post your comments on the battery drain after this update.. Feel free to post screenshots of the battery..

Since flashing my battery life and deep sleep battery life is greatly improved. Very pleased with this update.
Thanks for your reply.. I just installed the update and am a bit skeptical and feel as if the battery is draining faster when the screen is on.. Might be that when the phone is in idle or deep idle the battery would be dropping less significantly.. let us wait for other users to post their comments... hope fr the best...

I had no batt issues since upgrading to 4.1.2
with this new update battery life seems better. Left my phone at 10% before i slept and woke up to it still at 10% so deep sleep is really good
Thanks Paulito.. As i said i am suspecting that deep sleep is good now... but do you notice a faster drain when screen is on.. Do let us know.. I will also keep an eye on the battery stats for the coming weeks and keep all posted.. :beer:

Guys, install Batter Monitor Widget and do a real test to see what your standby and screen on consumption is in %/hour. We need real numbers, not anecdotes.
With DLL7 I get between 0.6 and 2%/hour drain in standby. Screen on averages 10-18%/hour. Gaming is usually 30%/hour. Wifi on, brightness on auto, location on, Facebook , google plus, tapatalk and 2 gmail accounts syncing with notifications.
I'd love to see what this new firmware gets under those conditions .
I can't wait until it's available for my variant. On DLL3 my battery was terrible! I went back to 4.1.1 where I can easily go all day with 70% of my battery remaining.
I shall install the battery monitor widget and will upload my findings in a couple of days..

Nothing required to enable it,
it should go to deep sleep, if it doesn't go to deep sleep then you have to find out which process stoping it to do so.

Hi.
I've got a strange problem on my gio. The battery is draining quite fast and when there is only one percent left it switches off. If I plug in the charger now I see, that there is more than half of the battery left. What can I do to use this battery time as well?
I already wiped battery stats and made a battery calibration but there was no change after that.

Same problem here.
I've tried some ROMs and since then, the battery is a disaster.
Charges really quick and drains even faster. I am talking about 15 min with wifi or 3g before it dies.

My battery is bad too but not as bad as yours even after I delete a whole bunch of apps I don't use ,turn off LTE (my area don't have it yet),
turn off Location scan in google map (betterbatterystats showing it checking my location every 2-5 minutes). Lets see how today goes.
Battery life has been amazing for me! I'm averaging about 13 hours of of juice from 4.5 hours of screen, in other words very heavy usage. I've been showing off to all the iPhone users at work, They now want a GS4.
I knew it. I freaking knew it was going to happen. Some arse buys a quad core "super" smartphone and then starts a thread crying about battery life. really? REALLY?!
well that's okay, i suppose. you can always post on XDA and beg for a dev to cook a kernel just for you that will miraculously give amazing battery life to your quad core super phone.
okay.... rant over. now time for a more tactful response.
IT'S A QUAD CORE SNAPDRAGON. i wouldn't get too bent out of shape on battery life. And I most certainly would not compare it to another device short of the HTC One.
Battery life is great for me. I only disabled some apps, kept most of the Samsung apps, but also disable all those Air/Smart gestures. I can go 2 days without charging with moderate use.
My battery has been alright, but I don't know why "google services" is showing such a high battery usage. I had the screen off for the last hour and google services is showing a 43 percent battery usage. That seems unusually high, no?
I did some investigating with "gsam battery monitor" and it showed that "networklocationlocator" has been causing wakelocks.
