Guys i have Lighning rom v6.1 with speedmod t27 kernel for 3 days now and i am noticing a high battery drain. I also tried using the follolwing apps but didnt notice any difference:

juicedefender using the balanced profile

autokiller memory

battery calibration after charging to 100%

rom manager

cpu master free and set the max to 1200 mhz and min to 200 mhz

android assistant

antutu benchmark made a test and got a total score of 5748

I was on stock firmware and kernel from seller without root before flashing to LR v6.1, did a cache and data wipe, flashed to stock XXKH3, Did a cache and data wipe, Flashed to LR v6.1 then flashed the kernel to speedmod t27

Appreciate some help to get a good battery life Thanks
[Galaxy S II Android Development] nraudigy2:
Uninstall Autokiller memory and probably juicedefender also. See how that goes.
[Galaxy S II Android Development] bhitt:
You can defeat your purpose when you start installing all sorts of apps that monitor. All of them put some drain themselves so when you add too many the monitoring apps can all add up to a big battery drain.

Hi. I have upgraded to LR 6.1 and speedkernel t28 and first bug which i noticed is minipaper widget is not working. When i click on it nothing happens. I really need that widget 'couse I'm useing it daily. Please help. How can I fix that?
[Galaxy S II Android Development] K-Paradise:
Because you flashed a non-stock custom-image.
[Galaxy S II Android Development] happyjacky:
Simple Question..

Can I upgrade from v6 to v6.1 without wipe??

Thank you.
[Galaxy S II Android Development] sniperwolf64:
Thanks for the replies

I uninstalled both juicedefender and autokill memory, flashed to speedmod t28, wiped cache data and dalvik. Then i installed only battery calibrator and cpu master free, will charge to 100% and do the calibration and see what happens.

I heard that some ppl getting a great battery life, can anyone suggest how they did it thanks
[Galaxy S II Android Development] Montala:
I am not quite sure what you mean by 'all models of galaxy s2' as I am only aware of one here in the U.K. which is the GT-I9100... which one do you have?

Yes you can for it's a no-wipe rom!

Android OS about 32%??

Hi,

Does anyone have a similar problem with android os?

I mentioned that this problem does only appear when wifi is enabled...

So, when wifi is enabled I get 80% battery usage of android os, after a few minutes its going down to 30%...

Tested with ninphetamine 2.1.3 and LR 5.0 as well as 6.1...
[Galaxy S II Android Development] newHere:):
i have the same issue...

i also noticed that the Android OS use a lot of the battery...

i didn't notice that the WIFI is the cause..

my WIFI is ON at most of the time...
[Galaxy S II Android Development] k1ng440:

Ok so I'm coming from darky rom 2 kh3 to this rom. Everything looks like it went well except one thing I am having an issue where openvpn will not work. I keep getting "ifconfig failed...". I've tried reinstalling busy box and that didn't change anything. I did an 'lsmod' and I noticed the tun driver is not loading. Does this litening rom come with tun.ko? I'm kind of new to this.

Thanks.
[Galaxy S II Android Development] vrekeno:
I don't know if it's the ROM, Go Launcher Ex, or WidgetLocker, but even with the correct setting within WL, the app that was open when the screen locked does not reopen after unlock, it always goes back to the home screen.

Guys, does my phone need to be rooted to install a ROM? This is my first time rooting/installing a rom. I get how to do it, but right now I have the stock Galaxy S2 (i9100) rom installed.

So does my phone need to be rooted for lightning rom?
[Galaxy S II Android Development] NoPompem:
It will be rooted after flashing. No worries.
[Galaxy S II Android Development] :
Thanks for the quick reply. Is there a rep system on XDA so I can rep you?

Also, a few more questions:

1. Will my apps and files be deleted after I install the ROM?

2. Will my battery life increase? I hope it will because the Stock ROM drains it extremely fast!

3. What should I do after I install the mod to maximize battery life?

4. What should I do in general after I install the mod to make my phone more user-friendly and overall a better phone?
[Galaxy S II Android Development] anupam_luv:
Even if I dont use the phone at all .... with WiFi on.... My battery life is only 7-8 hours after installing 6.1 ... upon checkin' I found Android OS is consuming 80% of battery...

I tried Wiping everythng off, clean install everythng possible but no luck.... I wonder why nobody's talkin about the battery life of 6.1 .....
[Galaxy S II Android Development] bhitt:
If you take a look back through this thread talk about battery life is at the heart of the discussions - "I have great battery life!" or "Why is the battery life so bad on LPX?" We all have the same phone. We all try different ways to improve the battery life. Obviously with so many in this group praising LP6.1 (and earlier) it is not the cause of your battery drain. Get a cup of tea and start reading about the last 100 pages or so and you will get a pretty good education. In the end, regardless of what you do you will discover that this is not a plain vanilla Nokia mob phone of yesterday that gets 4 days of battery. This is a smartphone that we all add apps to and enable it to do all sorts of things that we can show our friends. That all drinks juice. Good luck.
[Galaxy S II Android Development] KleoZy:
I had the same issue as you had. I tried to wipe and set default factory and to wipe the cache and dev. however I always get bootlooping.. therefore have to root it with default rom. anyway I tried all kinds of stuff, but ended up like what you had. Then I decided not to use the lock widget and it's working perfectly fine. for some reason I believe the lock widget does not like LitePro's rom. anyway I have no luck to it.

Btw I have jump ship, no longer using litepro's rom. It's was my first rom when

I flash and everything was flawless at V5. V6.0 and V6.1 drain too much of my battery life, even I have minimum widgets on screen, I also tried different Kernel, but still it does not last me that long. I ended up getting additional battery pack. But it's ridiculous to have this.. In the morning at 100% after charge and gone to work, after 2 hours I have 85%, with only 3G on. I use to get 92% after 3 hours with 3G on (V5 Litepro's rom). when I reach home at night at about 9pm, my phone is dead, hence with V5 I at least still having about 18% left.

the more I use it the more frustration i get, therefore ended up jump over to another rom which gives me more battery life.

nevertheless, litepro's rom is good in design, if only litepro can find a way to stop the drainage. I will be glad to provide information if required.
[Galaxy S II Android Development] JudgeyK:
Battery Drain

I'm still with the LitePro rom, but to backup the battery drain issue with more data, my phone now doesn't even last a day, I'm now charging twice a day.

For example, my phone was on charge last night until I wed to bed at 11:30pm, so the phone was at 100% and not used until 8am this morning, only 56% battery left, only 1 clock widget and the bloomberg Stocks widget running on screen with a live wallpaper, v5 did have a better battery life but I'm sure LitePro will come up with something, he always does...
[Galaxy S II Android Development] m444266:
for the rep, i think its the "Thanks" button. just guessing.

1. its supposed to be a no wipe therefore won't delete your files/apps.. but if coming from stock firmware, i forgot, you have to read previous pages. just do a backup first.

2. depends. too many factors can affect battery life. can be kernel, usage, setCPU settings, overall theme of you phone (light or dark). Check out my post for better idea.

3. if the kernel supports it, try setCPU and find a stable undervolted profile for you. read further on this since it kind of dangerous if you undervolt too much.

4. with custom rom/kernel, its already better than stock. its going to be your flavor from thereon.

a lot people are if only you read previous posts/pages. also its not just the rom involved re battery life. there still are kernel, theme, OC/UV, etc..

not sure if Litepro can help you with what else you chose to install in your phone, and how you run them. unless you provide more useful data that would point to possible reasons of your battery drain, you just cant point it on the rom.
[Galaxy S II Android Development] dejazz:
Just tried ragemod kernel, so far so good. 3 hrs 10% battery usage with multiple emails, calls, social apps, sms and games. For me, the best kernel so far.

Do a search on ragemod if u want to try the kernel

Forgotten to mention 3g and wifi is always on
[Galaxy S II Android Development] KleoZy:
wow, that seems alot on drainage.. maybe u can try out nip 2.1.3 kernel it does not drain that much

during a call screen turns black

When making or receiving a telephone call the screen turns black a few seconds after beginning the call. I have to push the home button to return to the call screen. Is this normal? If not, how can I avoid this? I'm on 6.1
[Galaxy S II Android Development] JudgeyK:
Appreciate what you are saying, and appreciate the work LitePro is doing, I am also a , all be it a Desktop / .Net Developer of some 20 years now, however even in my own job you have to look at the facts, my mobile has the same apps running as it did on v5, nothing else has been installed, no other widgets etc have been placed on the phones panels, I have Advanced Task Manager installed prior to V5 and set to autoshutdown taks every five minutes etc, not changed any of these settings since before v5 also, In development when something goes wrong you can only look at what has changed since it was last working ok, only thing I have done is install 6.1 so unless my battery is maybe "cattle trucked", there has to be an issue somewhere in the Rom, I'm not a android developer and know my limitations so have no idea what else to check.

I Again charged y phone this morning, after 2hrs 50 minutes at the time of this posting, battery is at 77% and I have not used it to make any phone calls, I opened Maps once or twice to search for a place but for less than a couple of minutes, have send 3 or 4 SMS messages and sync'd a few emails my phone Battery usage is reporting ;

Display at 63%

Android OS at 19%

Maps at 8%

Standby at 4%

Android System at 3%

Phone Idle at 2%

So looking at it I do have a live wallpaper running (Display 63%) but this was also on V5, I removed the Live wallpaper and see if that makes the difference and is somehow conflicting with 6.1 now...

[Galaxy S II Android Development] flagger:
For people with battery problems, try freezing Accuweather as even if you do not have the widget running, the OS may load it in the background and then it goes crazy polling the server for updates. I found out it was doing this when I looked in System Panel Lite when I forgot to freeze after a reinstall of Android (to get Samsung Dive working again).

Now getting about 6-9% loss over 9 hours of idling with 3G and wifi enabled with Ninph 2.1.3. I have also undervolted the cpu (800mV@200mhz), and a profile for screen off which maxes out at 500mhz.

Apps I froze are:

- Accuweather

- Ap Mobile

- Buddies Now

- FM Radio (Keep this if you listen to the radio)

- Game Hub

- IM 1.00

- Kobo

- Music Hub

- News & Weather

- Readers Hub

- Samsung Apps

- Samsung TTS (Doesn't work properly with Google Nav)

- Social Hub

- Video Maker (Keep this if you edit vids on the phone)

- Voice Command

- Yahoo finance

[Galaxy S II Android Development] huuub:
Hmmm, I have the same experience, but I believe I have it only since I installed handcent SMS, I froze it now, to see if that is really the cause. Are you using that?

Thanks-found this, but how do you put it on your phone? I would greatly prefer CWM because I cannot get Odin to recognize the galaxy at work.

[Galaxy S II Android Development] KleoZy:
I have done most of what you have listed and more. My home screen has a page with a music widget and 12 shortcuts, application are internet, citrix, camera, scanner, calculator, task manager, setting, skype, youtube, DI radio, clock and VM fusion. On V5, the battery can last me at least 9 to 11hours daily as I heavily use my phone for at least 4 to 5 hours daily at work. Mainly Citrix and VM Fusion.

however once I port over to V6 or V6.1, having the same setup that I did on V5, It can't even last 5 hours of usage. My phone normally gone dead before I reach home to charge it. This is how bad the situation it is.. I tried different kernel which indeed it helps.. niph 2.1.3 that is, but only last for another 1 to 2 hours.

I do appreciate what litepro have done for us, I do enjoy using his rom during V5. I thought of sticking to V5 but due to my own greed, I prefer to use up-to-date rom, kernel and modem. I had no choice but to jump ship. The rom I am using now allows me to at least use it for 9 or more hours. Do pardon me, no offense, just stating my experience with V6.0 and V6.1.

sorry if I did offended anyone here, especially the developer.

thank you!
[Galaxy S II Android Development] JudgeyK:
I know this is probably a stupid question, but how do you freeze an App, is that "force close" ?, and if it is, doe they simple start up again when your re-start your phone ?
[Galaxy S II Android Development] KleoZy:
using full version of Titanium Backup, you will be able to either Freeze apps from running or uninstall them totally. If apps are on Freeze mode, you will no have them running even if you reboot your handheld.

btw, nothing is a stupid question to me.. as everyone learn :P hope this help
[Galaxy S II Android Development] stefanjadex:
No, I don't use it. I use stock sms.

Do you have any idea what else could cause these random reboots?

Stefan
[Galaxy S II Android Development] stefanjadex:
I hope not to offend LitePro, I respect his work and I like his rom's, but I also need longer battery life because I'm also a heavy user. Can you pm me the name of the rom u are using now ?

[Galaxy S II Android Development] k1000716:
Unless you value form over function why not just get an extended battery? Then you won't have to worry about undervolting, removing apps etc. You can use whatever rom or apps you liek and won't have to gut your phone to make it last through the day.

I never used to get more than 12 hours from my battery, even with underclocking/undervolting and removing all the samsung apps (and not playing games). I spent $10 on the spiderfoot battery and now it's fine. Sure it's bigger, but I bought this phone to use, not look at...

Mugen have a 3500mAh battery for about $100, Momax have a 2700mAh for $45 and the spiderfoot battery is $10 for a 3500mAh (more like 2400-2700, but at $10 who cares?).

Just a thought.
[Galaxy S II Android Development] KleoZy:
I agree with what you mentioned.. I too gotten the 1 x 3500mAh and also 2 x 1800mAh, however it's so hard to charge the 1 x 3500mAh, I ended up with using the 2 x 1800mAh. I do understand the limitation of this android while dealing with my daily task at the server room, I should use a notebook instead.. but not enuff room inside the room, therefore no choice got to use this S2 which is by far the fastest handheld as compared to a dumb slow iphone4. (opps sorry no offence lol)

with the 1 x 3500mAh, it's the way to go but still takes longer time to fully charge it.

is it possible to update the firmware from 1.1 to 6.1 directly without doing a cache partition wipe and dalvik cache wipe? The other question I have is do I lose all my installed apps,msgs,contacts and etc? I have backed up the data though but just curious to know

-shortened battery life while using 3g,

-some graphics problems,

-random reboots;

Bug

there is a big with LR v6.1 after you select applications from the widget menu, If your apps are assorted in folders and not set in grid view you will find that they are all hidden if it is on a single page but if u grab a folder and split into 2 pages they will be shown. It is quite annoying but i think it is a bug so for the time being I have set it to grid view where it just lists all my folders and the apps within them.

[Galaxy S II Android Development] Teknovik:
I had a similar problem with Captivate but not with SGSII. You can check if the right 3G frequencies for Pelephone are enabled by the modem (I think they are 1850 and 2100) as they should be by default. You can do that with secret codes for SGSII that are available someplace on this site.

Also, you can check if you have the right carrier setup (available on the net)

Good luck
