So in general I get phenomenal battery life out of my lovely i777. Full day on a single charge, frequently with lots of juice to spare.
I am using the Titanium backup "freeze" TetherManager approach to get me some tethering without having to activate the obnoxious AT&T plan.
What I've noticed is battery life ends up being 1/2 of what it was if I activate tethering, even if I shut it off again right away. 'About phone' merely reports 'Android OS' as a top CPU user - looking higher than normal - and SystemPanel doesn't give me much better.
Has anyone else noticed this behavior?
ps - I used to use the WiFi tether app here http://code.google.com/p/android-wifi-tether/ but I found it was pretty glitchy .
Install better battery stats it on this site soe where cant link at the momemnt and see what is wakelocks u have killing ur phone or flash a rom that has tethering built in

That's weird... I've never had problems with tether continuing to hog battery beyond when I turn it off.
Of course I haven't used a UC base since November.
It sounds like tethering might be a trigger condition for the dreaded BT-AMP bug... See my "known battery drainers" reference in General along with tymong's "horrible battery life" thread in General.
Installed Better Battery Monitor. Regarding installing a ROM with tethering already present, I am actually kind of a TouchWiz fan, so prefer stock if I can roll with it. And technically, tethering *is* already present But I get your meaning
Entropy I checked out your known offenders post, very informative. I can't say for sure if this falls into that but maybe the battery monitor can help find out. SystemPanel reports for CPU usage within System Processes:
"events/0: 7.6%"
"suspend: 7.5%"
Here's a screen grab of the events/0 system manager graph:

Skip straight to the Wireshark part of my post...
I would suggest an I9100 Touchwiz-based firmware like XWLA4. IMO that was the pinnacle of Gingerbread on this device. Or you can try something ICS-based now.
I think I may just do that Entropy.
I feel like a jerk a little for mentioning that even after a reboot or two it continues to exhibit the behavior. Which doesn't really jive.
When I didn't tether for many days, my battery life was back to super awesome. And ,just to prove it to myself, I tried tethering today and sure enough the faster drain began. But after shutting down/rebooting, it continues. It almost seems like I have to pull the battery.
It may be time just to do ICS as you (and others) say.

Just wondering if anyone has discussed anything about battery life with this specific ROM and using Juice Defender Ultimate (or not).
I've done a quick search and didn't find anything and I looked on the viperROM thread and I saw the dev claimed he got 19 hours of battery life on it. I'm only getting around 9hrs on it now.
Any ideas\suggestions?

Try calibrating Ur battery. JDU is good to use. Also grab autostarts and stop apps from running in the background. After calibrating your battery life should almost double.
Sent from my Beastly EVO.. And did I mention it has 3D?
I use JD and Viper and no problems. Not real sure what my battery life is because I don't monitor it that much but if I take it off the charger at 6am by 4pm when I leave work it is usually around 75-80%. That is with probably an hour of podcast listening and a few other things like texts and phone calls. Not a power user but not completely ignored either.
It depends on usage... i ALWAYS make it a whole day. Light usage i made it more then two, with a bad wake lock that drained 20% before i noticed it.
I'm on Viper and I use not juice things. Here's the battery life I'm getting.

Download CPU Spy from the market and see if you have any widgets or apps preventing your phone from going into DEEP SLEEP.
I think this is woeful

This is the Q&A section of the board. You made a statement.
Apart from getting roughly 3 hrs of screen on time with around 63% of battery (this based purely on your screen shot & may not be entirely accurate given the complete lack of detail you've provided), this tells us pretty much nothing about your usage.
Well you've probably had about 3 hours screen time + 3g + Bluetooth on and connected as well. Seems fair to me.
Anyway, with so many battery related threads why not just post there instead of starting a new thread?
Sent from my GT-I9100T
Really, what for new thread?
Not clearly...
Turn on GSM-only in the network settings. Turn off bluetooth and auto-brightness. Sync and background data also sucks the hell out of your battery ^^
this is my usage. the battery keeps reducing even during idle, with no wakelocks, by around 3% an hour. i've set the setting to gsm only, turned off wifi & bluetooth, turned off auto syncing, but its still like this.
and in the 2nd attachment picture is the rom i'm using
any help would be greatly appreciated. thanks
looks good but how is your on screen time?
is that considered good? cause i've seen a straight line (only losing 1 to 2% over 8 hours) during screen off time. i don't quite like it now cause i always fully charge before sleep, and when i woke up it only remains 70%....
on screen time, i've never fully use from 100% to dead, so cant be sure...
Try the JuiceDefender application (Market). The free version is good enough to help you out. I use the ultimate version and using my phone all day long (3g, internet, sync, gps) I can easily got 40% to 50% left at night (full charge in the morning).
i dun think i'll need juice defender...i always do everything it does (i.e turning off 3g, wifi, bluetooth, sync, gps) when not in use...
You need autostarts, I paid for it and its made having my phone possible.

Don't use Juice Defender. Unless you want to use more battery. It uses far more juice than it claims to save if many people on XDA's experience using it holds true. Plus, as Thonney quite rightly pointed out, many (most) of us already do the things it does manually which takes all of a few seconds & costs zero battery.
Hi Guys,
Coming from a blackberry in the past, battery life hasnt been splendid for me at all. Having switched to sgs3, i am running the custom rom and kernel as stated on my siggy.
I am looking to have better battery life if possible. If you guys need more information let me know. I hope the single screenshot is enough.
Please comment if I am experiencing good battery life or not. I am also contemplating to download BetterBatteryStats to check my wakelocks.
Cheers,
Anjoid
P.S Feel free to post your battery life with a screenshot here as well, and I hope to learn more from that. and i cant seem to attach any file. when i click on attach, another window pops up that asks me to sign in. and when i do, it repeats the process.

Please do. There is a free APK of BetterBatteryStats here on Xda.
Since switching to Cyanogenmod9 with DXLF3 modem and Siyah Kernel, by standby battery drain has been between 1-2% with 3G and Sync enabled. It would be even somewhat better if it was von 2G. I also configured the kernel in ExTweaks for better responsiveness on the cost of battery life.
Please specify your usage and battery life. People who only use the phone for the odd phone call experience up to 5 days of battery life, while I usually have 20% left at the end of the day. Totally different usage scenarios.
Also make sure your network supports fast dormancy. To check, dial *#0011# on stock dialer (not Go Dialer!) and check the RRC state if the phone has not been transferring data for some time. It should state IDLE when the phone is connected to HSPA/3G.
Are others having this? i mean i go through a full battery about twice a day.... I cant figure out what is draining it so bad. i have used WLD, greenify, and bootmanager to try to figure it out..... None of my apps are ever on the battery list, and screen is around 50% usually with android system and android OS always being up the list. I always thought it was my bad signal strength at work but i had two weeks off and my phone NEVER lasted even close to a day.
I have factory reset once but loaded my same apps backup.
I heard someone else mention that the sprint has this weird battery drain that is explainable and was wondering if others see that also.
I am on the search for a 6000+ mah battery i know it will have a replacement back plate but i don't want the whole case thing like the 9000 zero lemon.
Sounds like kernel wakelock
As of the last two days i have also been experiencing much faster battery drain. Have had the phone since launch and never had this problem.
I do not use the device in excess. Very few if any phone calls per day, some texting and gmail, occasional skim of xda, huffpo, phandroid apps and very light Twitter use if bored and not near the computer.
Battery has dipped 5% since writing this post...that's all of 1-2 minutes in use.

That's not normal for a Sprint LG G3. A couple of questions:
Have you looked at the battery stats page to see what app(s) are using the most battery? I'd suggest taking a screen shot of that page and posting it here.
Have you tried rebooting the phone? If there's an app or process running out of control that will often clear it up.
Are you rooted? If so, install better battery stats so we can get a better look at what's eating the battery.
Finally, you might want to take a look at this thread: http://forums.androidcentral.com/sa...android-system-eating-your-battery-check.html
While it's unlikely you have the same problem I did, the tools and techniques I used to debug it might be useful for you.
Gonna wait for some custom roms to see if the problem just goes away.

Dude the battery app should show you what is causing it. Something has gone rouge!!! I just had my weather app running in the background using GPS for 5 hours, yeah my battery went way down. Freeze some BS apps. I routinely get 30 hrs plus on a single charge. Not the phone itself something you are using is causingi it.
As requested, my craptastic battery info. Brightness was 83.

bought BBS, phone is up stairs charging... imagine that... will post those screens next drain...
I have a Mate 10 pro with very high battery drain. During the night 6-8hours it can drop from 100% to in worst case 75%.
I have done many factory resets and just installed basic apps (for me). Up til now I've been used dual SIMs. But this morning I removed one of the SIMs to see if that makes any difference.

To start with, Google Services (in their fifteen million different flavours) will chew through a lot of battery power in the first couple of hours after a factory reset.
Secondly, have you tried doing a tiered installation of your non-standard apps, to see at which point the battery starts going South? It may be that one or more of your apps don't know how to run properly under Oreo? I'd be paying particular attention to Samsung's apps, as their programmers have never been known to care about how the software will run on non-Samsung devices.
Thirdly, have you investigated why the apps which were auto-launched, were auto-launched? If (for example) Slides was auto-launched because you were looking at a presentation from an e-mail, then fine - but I've encountered apps in the past which keep trying to re-start themselves for no valid reason (most notably apps which try to maintain ad revenue even when you're not using them).
Finally, though the signal strength on your screenshots would indicate that you have decent coverage, if you're in a borderline area and the 'phone is having to constantly switch between LTE/UMTS/GSM just to remain connected, that will chew through a lot of battery without anything worthwhile to show for it. If this is the case with either of your SIMs, try forcing that SIM to remain on a single standard (for example, limit it to just UMTS/GSM); that helped me in the past with an Asus PadFone 2 and the rather pathetic carrier I was using at the time (yes, it was Optus).
This is happening to me as well. Started a few days ago, maybe a week I think. All of a sudden, out of nowhere. No apps draining battery. 20% ish drain during the night. Seems like there are many users having this problem the last week after a quick google search.
Last night I went to bed at 2:00. The battery started to drain from 5:00-10:00. No apps have been draining battery during this time.
