This doesn't make sense but... - Samsung Epic 4G Touch

For some reason when my battery gets real low, like below 5%, my phone starts to roam and I have no data.
If I reboot my phone it comes back.
I'm on CodeName Alpha 2 and EL29 modem.
Is this just a bug or something else?

Check your power saving settings. It might shut off your internet connection at 5%

WiFi turns off by itself

Got my sgs3 Sunday and when I got home turned on WiFi and started playing with it I notice that I lose network for a second after about 15 mins and my WiFi icon on the status bar disappear but network comes back on .. but in settings it is greyed out and I can't turn it off then back on till I reboot 0_o...thought maybe after I rooted and flash AOKP it would be fixed but no! I'm on T-Mobile and AOKP..so is it a bad WiFi driver or...? Any ideas?
#*0011# press the menu key. Select wifi. uncheck wifi power saver mode. Its should be green when on black off. Make sure its not on and done go back to home screen. Your phone should reboot the wifi driver and your done.
This method works for 4.0.4 any of the roms. Cm10 doesn't work. Cm9 haven't tried but I'm sure it'll work for u.
Hit the thanks if I've helped!

JB has these wifi issues I was expiriencing the same problems on cm10 as well. (I know not the same but both are jb) I decided to downgrade to the intrigue rom r3. It has smooth transitions. Real buttery and it let me access the wifi power saver mode by down ng the method above. I'll look into aokp and see if I can find a fix for u.

does aokp have a setting like i think TW has where if the wifi signal is too weak it will use network instead?

Question: are you rebooting your phone when this happens?
Cuz if you are that's normal on every reboot you have to go back and turn it off again.

Sent from my SGH-T999 using Tapatalk 2
would the method above work for me? since yesterday, my wifi kept turning on by itself. After I turned the wifi off for like a couple minutes then it'll turn on automatically again. I have the Keep Wifi on during sleep set as "only when plugged in" and it never happen to be before until yesterday. My power saving in the setting menu has always been off too. Please help! :crying::crying:
Install the app called "Wifi Fixer" app to the solve the issue.
Whatever Google did to cause a variety of wakelock problems, having a strong wifi signal seems to solve them. Apparently, wakelocks occur when there are unreliable connections to Google's servers.

How about screenshots without the volume indicator? You can also try GSam Battery Monitor from the Play Store, to get a little more information on what is eating the battery.

What's your screen on time.
Looked kinda like liteflow might be causing problems?
Cell Standby i think is the one that is coded wrong and is lying, ignore that one.
If you press Android System in settings, battery it will show you the top components being used
Also in dev options look for and check Show CPU Usage. It will show whats using the cpu in the top right of your screen. Watch for what stays in the top few spots in the list.
There may have been something that didnt like the update. Try first uninstalling apps and if that helps reinstall them clean, no data restore. If you continue to have problems backup all data and factory reset. Start clean.
If all else fails use odin to flash the full LH2 fw.
LH2 should be a fairly stable build. Most have no issues and many get outstanding battery life. Im willing to bet its either an app or the way you updated or both.

Yesterday before i delete liteflow the android system was always ontop of the list but now it is at the very end i hope that it was simply that because i have way too many apps to delete and re install :/ but ill see how it goes today i got root and cwm so ill probably odin the lh2 as you suggested ..

That's really not THAT bad for a screen on time. I saw your screenshots in the OP, and you were down to 80% in only two hours of being on the battery, but you had the screen on for almost an hour of those two hours; 20%/hr for the first few hours is pretty normal. It's not stellar, but I wouldn't say it's an epic drain that being said, I'm sure you could squeeze some more juice out of it, and prob is just an app causing more drain than usual.
Also when doing a screenshot, it helps to hit the power button first, then the volume, so you don't get the volume pop up every time.

3:30 screen on time it's good no matter how you use your phone. I got 2.45 hours on screen with 1day and 6 hours. I've had issues with liteflow and battery as well. Others say they don't, it seems to depend on how you set the phone and liteflow to work.

Yes, use it now (Ulitmate) I have found nothing wrong personally. Mine's set for Data on with screen on, Data off screen off.. I don't have a schedule set or anything (i'm always off and on the phone anyway) does increase the battery life a bit.. Download, try it for a bit.. see what you think overall.
I did use it before, just the light version. it was indeed a battery extender. But now I am using ON(X).

Nope. IMO, battery saving apps like Juice defender burn more battery than they claim to save.

Juice defender WILL help. I get about 24hrs to a charge. It simply disables data/location/wifi when not in use and can be customized to run different ways for different apps
-SlimBean...the bulimic's choice for the Galaxy III
Hope this helps. It's fully customizable and it does wonders. U can train it to learn your wifi and after a while, never touch the toggle again. Use it for games so they don't go online and pick up those annoying ads (if your unrooted). And u can schedule when the net comes on to get emails and so forth when your not touching you phone.

Been using Ultimate from the beginning and if set up correctly is the difference between night and day for battery life. It works very well with no problems whatsoever on my end.
+1 When setup properly it can save a lot of juice. Or turn data off when not needed it will save a little more than using JD. But I rather have JD running so things are seamless. For Streaming audio like Spotify I find setting for enable/screen off works the best.

Be honest and tell people you have an extended battery.
i got a small issue with JD ultimate:
i set it quite correctly i think, but then, it prevents datas from coming to my phone, even when they're enabled.
let me explain better:
i set it so datas are off when screen is off and on when screen is on.
so i turn my phone on, datas take smth like 5 to 10 seconds to enable, everything normal till here, then the small H or G appear meaning i'm connected through 3G, but even then, i'm still offline... i wait, and wait 5 mins, but still, the H or G is visible on top right of my screen but.. no data.
i disable juice defender, restart my phone, didn't solve.
then i uninstall it completely, restard my phone, and everything works fine again...
anyone could help me on this one?

Battery does not list app usage

Battery doesn't show what apps are running
All my battery displays is Screen,Device Idle, and Wifi
It shows no other third party app that is running. This can only be temporarily fixed by rebooting my Note 2. Which then it happens again after full charging the device.
Is there a fix to this? I barely got it and it is bugging the crap out of me

This happen to mine too.. when i turn off auto sync in Settings>Data Usage>Left menu then turn off Auto sync data.. But good in battery saving..
My Note 2 just started doing this as well. Settings> Battery and all it shows is the overall usage graph and Android OS 100%. If I click on Android OS it shows 298 days of usage. I tried deleting the batterystats.bin file/full charge/reboot etc but that didn't work.
Anyone have any ideas?

Fixed it.
Ran it down until it turned off/died.
Plugged in stock charger.
Once fully charged..green LED...powered on.
Booted into CWM from restart menu.
Wiped both caches.
Wiped battery stats.
Reboot.
Unplug from charger while at 100%.
Thought I followed these steps before but apparently I didn't.
Back to normal.

Any ways to save battery other than settings?

I really like how my settings are. Sync settings are minimal...but its been off the charger for 3.5 hours with moderate use and its at 76%....im looking for how to undervolt (not underclock) or any battery saving tweaks.
Also...im on synergy rom and cant change the setting so there is no LTE..why? And quck question...is there a key strock to get to recovery...new here
Sent from my SAMSUNG-SGH-I747 using xda app-developers app
Turn off the Location access, and dim the screen as much as you like... I just got 36hrs with 3hr screen time with only those changes... To undervolt, you need to be running a custom kernel, and use a tool like SetCPU, Voltage Control, or KTweaker if the kernel is KT... To get into recovery, use the advanced power menu, or while it's off, Vol Up + Home + Power... Check your APN settings for LTE...
I've found that undervolting is a pain, and doesn't save me anymore battery than stock voltages... Mess around with it and decide...

I'm sure it has some sort of battery use, it's always looking for motion... Whether turning it off or not will help a noticeable amount, I'm really not sure, it's a TouchWiz feature, I haven't ran a TouchWiz ROM the entire life of my phone...
Any TouchWiz junkies out there who have noticed a difference turning it off?
find and eliminate wake locks. disable bloat apps. run a good light rom with battery saving kernal. turn off what you dont need. thats all really. if your battery is dying fast find whats keeping your phonw awake and do something about it. I can go to bed with phone at 100 and wake up 8 hours later at 99. also go to bed 50 and wake up 49 etc. you should expect the same. on 3g I get at least 5 hours of screen if im heavily using all day. but battery life is up to you. you want to be minimalist like me you can expect similar results.

You can dial *#0011# then hit Menu > Wi-Fi Settings and make sure the WiFi sleep policy is enabled. Every time your phone sleeps, WiFi is disabled and you have to reconnect, but it does help on battery life.

I dont think it does. uses battery to turn on and off the wifi. just leave it on. ny rom is wicked v8 and intergalactic 2.5 kernal. weird combo I guess. but it just works for now
I squeezed 7 hours display (18+ hours standby) on a single charge with auto brightness on and LTE and sync on all the time. Routinely I get 5+. I would say, get a good rom n kernel combination (only way to know is to try out).
