Battery drain

Speaking with a helpful young programmer around here help my drain issues a lot. I had to unplug at 5:30am for work, and wouldn't have access to charge again until 5:30pm. On most days, I would still see 20-40% battery left, but somedays, I would loose 50% by 10am, and be dead by noon. I have several chargers around from the myriad other electronics i "play" with, and had a habit of just grabbing the closest one. He say's to me that I should go a week with only the factory cable, and factory adapter, and see how it went. I tried this, and my battery problems disappeared. Apparently. not all cables are created equally, and the ones that do not work quite right, may still charge your device, but in disconnecting it causes wake-locks on some system apps. For me, It was Gallery, and Cell Standby. There were many more on other checks. A quick reboot after unplugging resets the wake locks, so if you have a faulty cable and have to use it, try rebooting as soon as you unplug. Worked for me, before i just threw the other cables away. Now on a moderate use 10 hour day, I come home with 50-60-%battery,

ya using a charger that wasnt the original one with your phone does cause issues i learned that with my galaxy s 2

My Battery life is not that bad i think, around 5hrs of screen time, 12-14hrs total, but it is weird how "Android System" takes a big chunk of battery juice, is JB reporting wrong information here? i have tried logging running processes and their CPU usage is minimum, so, what is happening here?

Mine runs on CSROM 1.5 "the bmb!".

Getting sensational battery life with hyperdrive rom and deviant kernel. I don't think it can get better than this.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] jdhommert:
I've gone through about 2 cycles now.

The first one I ran the battery down to 50% in about 3 hours, which I thought was actually pretty good because i was using the **** out of the device tinkering, downloading, installing, streaming pandora, doing speed tests etc. I was only on LTE when I walked outside, using wifi the whole time. I don't get LTE in my house which is probably for the best for battery/data considering I have wifi in my house. Screen was on all 3 hours or so. I went to sleep and left pandora playing trying to drain the battery, and turned it back on in the middle of the night too. Woke up and the battery said around 13 hours I think??? Like I said I was trying to drain the battery and raping it so I'm suprised it lasted that long.

Second cycle i got 15 or 16 hours out of I think. I think I got about 5 hours of screen time too. Maybe an hour or two on LTE the rest on HSPA+/wifi. This was when i wasn't at work and could use the device whenever. I text a lot too, but sometimes use mighty text on my computer so my screen isn't always on as long as it might be for some people.

On the 3rd cycle I'm trying to keep it in power saving mode most of the time. My buddies played with it for about 10 minutes or so without power saving on. Right now I'm at 70% with almost an hour of screen on time. About an hour or two was LTE but with only the 10 mins or so my buddies played with it as far as use. HSPA+/wifi since.

I certainly think there is enough battery on this thing to easily last a full day at work away from a charger and probably enough time to last if you have to go somewhere after too. I'd think you should be able to get at least 10 hours of moderate use on LTE..but again I have barely had the phone on LTE so idk how much faster it drains the battery. You might be able to get 15 hours of moderate use on lte who knows. Battery should only get better after some custom roms especially if they have LTE toggles. :)
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] tuffluck:
2 hours of phone calls, 2.5 hours screen time, 13 hours online, 25% left. Very little LTE though, i dont get service at work and use wifi at home. Still, pretty good. Also i use juice defender and i think it helps.

[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] SightSeeker:
This might not look that great to some but I was on this hard for the 8 hours+ I was using it. I streamed pandora for 2 hours and probably turned it on and off 50 times or more at the gym between sets. I hope after the honeymoon stage I can make it through a day. This was auto brightness, cpu battery saver only.

Standby time is high like others have mentioned.

Battery problem!!!

Good afternoon, everyone.

I since I have my AT & T Galaxy S3 have been having problems with the battery, as this never reaches 100 & and not what is the reason. Change charger, usb cable, and do nothing to get it reaches 100% loaded. It's been two months since I have the phone and I installed AOKP 4.2.2 thinking that would solve the problem and nothing. The phone my sister and my cousin also have the same problem, the 3 buyer right through amazon.

Another problem with two of these phones (mine and my sister) is the loading time, mine it took around 5 hours and I looked like it was too much. After a month this improved and now only takes me two hours. But my sister is taking five or more hours.

I wonder if anyone here has had a similar problem and has found the solution?!?!?!?! Thank you very much in advance for all the help you can give me.

[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] agentfusion:
Using Dandroid 3.8 AOSP-alike, I average about 15mins of screen on time per 1% battery loss with WiFi on, no power saving options, and manually adjusting the backlight keeping it as low as I can and still able to see everything.

Also note that I use black EVERYTHING when I can since organic light emitting diode screens only use juice when displaying a color. The individual pixels don't light up when displaying black.

So, average battery life on a full charge IF I'm not using GPS: about 26 hours, give or take.

If I'm using GPS, or texting a lot (which is normal for me) I get around 10 hours on a full charge. Still planning on buying a zerolemon 7000mAh battery because I'd love to be able to turn my screen way up, use GPS a lot on foot or on bike in the woods, music, photography, tv shows while I'm trying to fall asleep while camping, etc.

Depending upon what ROM I am running, I have gotten just over 48 hours using an Anker 4400mAh extended battery. Don't remember which ROMs right now since I have been flashing several different ones to see how I like them and how the battery life is. I think they were Deadly Venom and AxisM.

stock tw roms normally last much longer because they have access to better drivers etc. If you're still asking this kind of question, then stay on the 4.1.2 roms, I don't think you're ready to try flashing bootloaders and modems to use the leaked 4.3 tw roms.

also, best whatever roms are ususally frowned upon, because everyone's usage and phone varies a little, so there's really no best. YMMV.

Task650's

This incident I was driving for approximately an hour in SoCal from Norwalk to Temecula (using Google Navigation for the LOLs), and when I unplugged the car charger and touched the phone, it was so hot that I refused to touch it (particularly the back of the phone, the bottom part where the SIM card is). That seems to be the common theme when my battery remaining just goes down the crapper.

Right now, I'm not a big fan of the battery life of this phone when it comes to the screen being on, and I typically have it about 1/4th brightness. I'll try to get some typical use screens sometime (music, some browsing) but as far as I can remember, I've never been able to get to even 3 hours of screen usage.

EDIT: Also, I never actually had wi-fi on. Dunno why it shows up as on.

[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] ares117:
I didnt use anything which had a super high demand on the battery, just regular stuff. For example, most of the screen on time was either surfing web sites (such as news or reddit), checking emails and facebook, sending text messages or just checking the time. I also listened to music for about 20 minutes, and as you can see in my screenshot, I also had about 20 minutes of phone calls. I played about 15 minutes of chess but that's not very demanding on the battery. I think I should mention that I had wifi available the entire day and did not turn on my data even once.

I wouldn't say outrageously better but ,yes, it is well known that stock gets better life. I went stock (though I did run a launcher) for about a year before switching to a custom rom.
