Hi all
So I rooted finally . . . .
Now my main reason for rooting was the battery drain. . .
Ive got titanium backup on my phone . ..
What is the best things to freeze/unistall to improve my battery life??
also any further simple things I should do now Ive rooted??
Thanks
Do you know what was causing your battery drain in the first place? On my phone it was wifi sharing and maps, but I've since rooted and installed a custom ROM (Lite'ning), and am hoping this fixes it.
I really don't know. . .my battery was draining in idle and I yesterday it went nuts and just drained down to 15% from 50 % in few hours .. not even using my phone. . . .
Really wanna know whats my nest moves now to improve battery
As battery drain was your concern, I'd highly advice you to install Better Battery Stats and see under Partial Wakelocks.
Search for it in XDA.

Got a interactive app now. . .
How can I delete that??
Can find it in titanium or in file manager??
Hi i am recently encountering a massive battery drain when phone is on idle. Screen off, wifi and everything off even syncs. Brightness only 15%. Battery is draining average of 10% per 2 hours on standby. I uninstalled all apps prior to this prob but still nothings changed. It wasnt like this before. I downloaded betterbattery and i have 3 things on top list under kernel wakelock. The smdcntl0, smdcntl1 and radio interface. But i have no idea what they are..
By any chance i have a virus that only a repair would fix?
Also, i heard that there is a new firmware for xperia s. If i downloaded the firmware in the future will that reset and fix my phone's problem? Cause i dont want to back up 2 g worth of mp3 for a single repair. Perhaps there are simpler solutions.. Any answer would be appreciated.. Thanks..
Ps. Im using stock ics no root no nothing and i dont plan on rooting.
same problem for me on stock 2.45 and cm 9.1
It's the modem.
Hello, I have installed BetterBatteryStats and CPU SPY, because I noticed that I had a faster than normal battery consumption when the tab was left alone.
I made a 30 mins test Wifi OFF, Flight Mode On, where the 29 mins of them showed me l2_hsic under Kernel Wakelock -> Since Unplugged.
Does anyone know what causes this and how to prevent it ?
Thank you.
( I am running Stock ICS 4.0.4 rooted)
Same problem here.
I am also having this issue as well using stock ics.
Hopefully someone might have an idea on solving this issue.
seems its a bug in 4.03 or 4.04 Roms , I searched internet and could not find any solution , The idea is this kernel wakelock is caused by some settings related issues like gps or wife or... , now I'm doing some investigation and try to find the root cause, however I wish an expert could bring some solution here
As I promised to report here is what I experienced:
My Tablet is P7500 and I did wipe , remove many applications , put in flight mode , disable this and that ,..... none of them where effective
and finally:
2 weeks ago I removed my simcard from tablet , Just to try to solve the issue I reinsert the sim and as you can see in attachment after around 45 minutes no l2_hsic wakelock .
what I mentioned above doesnt mean everybody have the same issue but I think its related to the sim and network discovery because during last 2 weeks I received notification in my status bar that says can not find network although it was on flight mode

You said 2 weeks ago you removed simcard from tablet and no more l2_hsic wakelock. Is your problem solved permanently?
l2_hsic

Hi,
I have the exact same problem.
Tried all possible solutions with no result.
The only way is to let the Flight mode OFF, at least in my case, with stock rom TPH, WLP5.
I'm going nuts with this problem.
Yesterday I thought I had found the problem. DId several tests of getting in and out of the Flight Mode and everything was looking perfect, 5 & 6 hours of deep sleep. Then i connected a usb flash drive, that apparently also causes a kernel problem (see other posts about usb unmount). Rebooted the Tablet to solve the problem and here i go again with the l2_hsic preventing the device to deep sleep....:crying:
Hello,
I have the exact same problem and it's driving me crazy. Was anyone able to find out something new?
Thanks,
hugo.
A Custom ROM is the Solution
Hey guys, I am also a proud owner of the Galaxy Tab 10.1 GT-P7500 but unfortunately, Samsung forgot about their flagship tablet and screwed up the kernel in an otherwise utterly awesome ICS Update. The only method to solve this problem is flashing another ROM no other go. This fixed the Deep Sleep issue for me, 12 and a half hours and I'm only down to 96%. So I suggest you Root your tab ( Instructions in this link:http://www.youtube.com/watch?v=kBd9gMFCCrA ) and flash Toldo's JellyBeanRom ICS v6 ( This link:http://forum.xda-developers.com/showthread.php?t=1813651 ) and then enjoy the great Honeycomb battery standby on ICS (If you can't understand how to flash the ROM PM me :good
Happy Flashing Guys
i have toldo jellybeanrom v6 already flashed few weeks ago.. nothings changed, battery drain still remaining.
The problem is still there. AOKP 4.1.1 JellyBean, P7500 with sim card in. Same on CM10.
BTW. This is not a system issue (ICS or JellyBean). Rather something wrong in the kernels that come from Samsung. On my HTC One X (ICS) there is no such issue. Maybe some skilled developer could look at the difference in the source of this module between HOX and P7500?

I will try to update the code w/ Samsung Galaxy S3 source code in my kernel...
I will inform you if there's any progress with this

Hey guys,need some help,i have KitKat Rom (cyanfox v2.0.2) and i have some major battery issues.I have been running this RoM for quite some time ,no issues.But the last month or so i have been experiencing major battery mood swings (issues) such as :
- battery is at 78% (i.e.) and i reboot the phone ,and now it shows its at 14%
- battery is at 99% and turn on wifi ,battery is at 10% within 15min.
- and similar
Im afraid the battery is damaged or something,usually i would not post questions about battery life,but this is a serious problem,and i dont know what to do.
Need help in any form ?
Buy new battery.
Definitely a battery problem. You could try changing roms but that won't help much.
I have a rooted vz s4 running all the latest ota's. This thing drains so fast while on cellular. Can't make it till the afternoon. Better battery stats says that "msm_hsic_host" is killing my battery...
Any fixes for this? I searched but maybe I did not search correctly cause I have seen no fixes.
Thanks in advance
Super-duper late but any luck? I'm having the same problem but only when it the screen is on not sure if that's a problem. Lol
