Stock , or custom rooted ? Where can i find ?
Or this is just the modem ?
Im newbie in android....sorry
Villain 1.4 good battery life .
Multiple flashing of roms degrades battery life unless you reset battery stats and give the battery time to readjust + 80 %of battery drain is user apps /rogue aps constantly trying to connect /wake phone .
jje
I reset the bat every time that i do a flash when reach 100 %
Thanks
Villain 1.4 includes de modem ?

No idea if it has a German modem sorry .

all stock
like brand new when u get a new phone
u can get pure stock roms from here

WOW.....your device is so hard work, but I would like to know you whether open the auto-sync?! you can download the app for Juicedefender or Green Power to control the data/ Wifi, it can save power.
I use Lite'ning V1.5 and use Juicedefender for my Galaxy S II, it can work for 2 days for one charge
stock KF3 works great for me. You shouldn't need a special ROM to get decent battery time.
What is the display on time when the battery is getting close to empty? That tells a lot how you use the phone.
In the past i got a lot of Screen 65 %
Now android ios is taking 45 %....

Ok...3 years of iphone...
Btw what is your best rom regarding power consuption ?
Must admit the battery on this SGS2 is a bit of a pain.
It takes all day to charge from 20% to FULL then about half a day to drain back to about 20%...
my Iphone 4 I have just sold, would charge up to full in a couple of hours and last all day.
I am doing pretty much the same things

Litening rom 1.5
Dont forget to remove all the junk stuff (hubs,etc.)
Use tegrak overclock and undervolt
result for me= after 12 hours with medium usage still 60% left

i will help save you some headache, the SGS2 will never get quite as good battery life as the iphone 4 does. you may be able to improve it, but it will never match the IP4 unfortunately. it sucks i know.

can confirm that
now i am on litening rom 2.1 and i got the felling battery life got a lot better.
im also using tegrak. just search in his thread to get some values that fit your phone.
aditionaly i am using juice defender wich is a great app. i have set it to enable (while in sleep) data every 30 min to sync mails and stuff. when you unlock your phone it always enables data automaticly. thats enough for me and battery lasts way longer. just give it a try...
Hi everyone !
I´ve been flashing roms frequently for like a year or so, testing each and every rom released.
Ones are clearly better than others,but every developer is making a good job.
The thing is, since my last 3 flashes,i'm experiencing a HUGE battery drain once i'm over 3G network, so i'm considering flashing a STOCK rom so i can use my phone correctly.
Which is the best BASE ROM i can have ? (JPS,JPQ,JPM... 2.2 Froyo ofc).
I'm tired of flashing and reflashing things that are not working 100%, stability is VERY important.
Also, any idea of whats happening to my 3G ? My battery life is OK once i'm not using the 3G network,but once i turn it on my battery goes down like water in a waterfall.
Thanks in advance.

JPM was very stable. But you can try JPS too.

Actually, all i need is a rom that does not EAT my battery over 3G network.
I guess i've messed up my battery flashing all those roms.
Since i've already calibrated it 3 times and it still draining as much as it was before the whole process

Over 3G usage ...you will definitely get low battery, due to resource usage over the high speed network.
Try My ROM and let me know if it helps your cause ... though my ROM is based on XXJPS and have lots of battery Customization to improve performance the battery backup as well.

I dont think it is normal to have my battery drained like hell over 3G Networks...
I mean,i wasnt like that,it started someday and never stopped.
Do you think that flashing a STOCK rom would fix it ?
All i want is to be able to stay connected to 3G for like 4-5 hours,maybe more.
If i turn it on,my battery drops to ZERO in matter of minutes.
Then its time to change your battery.same thing happens with me.i have already changed so many roms...but after data network on battery drops in 10min...

is my battery damaged ? I have tried many ROMs and on all of them I'm having a very bad battery life. I have everything turned off and my brightness is 0% and the battery drains super fast. what should I do ?
1. Do factory reset
2. Exchange the phone if option 1 doesn't work...good working G2s don't perform like your phone is @ the moment

What's the problem with that exactly? (Most issues with battery life are user problems - usually a poor wipe / flash regime and using poor quality apps and heavy syncing. I assume you have used the usual wakelock detection procedures).

Por signal will drain your battery.
Mostly apps are draining it post a screanshots of your battery stats.
Install gsam to see what's draining..

I would try to reset everything to factory, see how it goes then. If not, flash custom rom/kernel, tweak cpu and search for wakelocks. If the problem is still present, get a new battery.

1% / 3mins sounds like 5 hours on battery to me. Reasonable, but not great.
Depends if you have your screen on during that time or not, and what brightness, and what tasks it is doing. If that is screen off at all, then it's horrible. If full brightness screen-on for the whole time, then it's ok.

Yep. If you go to Battery, is your phone intensivly active while screen is off?
My Battery atm: 1d 3h 14m with 53m screen on time at 87%, but pretty much all day on wlan.

If your phone is the international version, you have the option to buy a new battery And swap it out. I would try this since batteries are pretty cheap at the moment.
If it still drains after all these things only then do I recommend you return the phone for a new one

Culd be som app running that is draining it.
Install a battery monitor. Like gsam then u can see what's drainimg the battery.
Try delete google+. Giving a lot wakelocks. If u are rooted install wakelock detector and let it run 2 or 3 hours and see if its under 20%

I would suggest to stop draining processes first. If stopping it doesn't cause any problems i would rather freeze than delet it.
But if it's caused by a ****ty app you downloaded, delete it right away.
if none works, get warranty
When i switch another rom, every time my battery draining is terrible so i think this is the battery states fault.
Anyone tell me what is the better way to fix this issue?

What do you mean?
It's normal for a rom to use more battery the first time you use it. Besides that there is no such thing as a fake battery state.
Ok sir
I use amlify, freenify, and boot manager but...
After 3 days using this rom or every CM based rom i lost 25% of battery on 7 hour without using my device.
Sorry for my bad english.

well obviously everything that is not plugged-in , on the electricity needs power to run, but i think you lost the point of his message,
i think he means that 25% is a lot, for a phone in no use.

I lose more with data on. I think it's normal result for 7 hours.
Custom ROMs need a "settling in" period where the software polls the hardware for its capabilities. The OP may simply be impatient and expecting instant benefits from the ROM without giving it a chance to adjust itself to the hardware. 25% in 7 hours is typical for someone not using Greenify, but it's arguably high for someone using that app. If the OP isn't being impatient, it makes me wonder how old the OP's battery is, since a new battery shouldn't be having this much drain.
The OP would greatly benefit from updating to an Android 6 ROM. In situations where the phone is simply sitting there, Doze kicks Greenify's a** all over the park.
Just wanted to point out, without evidence yet, that battery life on Nougat (Concept update 38.3.A.0.107) is amazing. I'm talking about days here.
¿Anyone else experiencing this?
As for the evidence, I will charge my phone to 100% today and upload a battery life screencap as soon as I can.
What? I need that firmware! My battery goes from 80 to 70 in 5 minutes On screen time!!!
Hi,
Just a quick update with a screenshot. Just 2h short of a day with 14% to go, the mostly horizontal part of the graph happened when I was asleep.
SOT for that is 3h13m

I dont understand.. my phone is brand new, I have optimasations, underclock and everything except wifi is off.. what am I doing wrong? I have also calibrated the battery, full discharge ans full charge, its not any app im using since with stock and. nothing. installed battery runs the same.. Also the camera is worse after the drm fix than before drm fix (too much noise) the hell is wrong with my phone??

No, I am using the poison nougat rom. Actually, I have been using gsam for 2 weeks I think, just like you I cannot find the problem. My SOT is 3 hours, 4 hours at best. And keep in mind that is with very simple usage , not any intense apps or games
