[Q] Battery going old? - Galaxy S II Q&A, Help & Troubleshooting

Hey, my phone has been bought in on September 2011.
I noticed battery keeps my phone shorter than it's been before.
Is it either by ICS or battery is just getting old and less reliable?
I use XWLPG and my hourly battery usage is about 0.8% to 1.4% (battery monitor).
Sometimes after I unplug from charger and keep phone alone, battery usage is about 0.1%... dunno why and how....
I use only few background apps:
- network type marker (to show I am in either 3G or 2G)
- TotallRecall for call recording
I know in GB I could unplug phone for night and by few hours I could loss max 1-2 percent (sometimes even 0% by 6 hours).
Now I lose usually 5-7%.
Do you have similar symptoms in your phones?

hey pal i also bought my s2 during the same period and my batt is good enough even now
u have to check which apps is causing the batt drain for u since in ICS, also turn off ur data connection when not in use since they also cause heavy batt drain
u can try Better battery app from store to see the wakelocks that is causing batt drain
ps- before all change ur modem and see

There are a couple of reasons why your battery is performing like that.
Some of my friends have reported lesser battery life when they switched to ICS, even when running the exact same apps. So you might want to try different ICS firmwares/roms to see if that will make a difference. Although, I'm using XWLPG also and it drops ~7% overnight. Same as your's.
Also, if you find that your battery levels are wack, then you might have a faulty battery. On my GNote, I sometimes have to push the battery upwards while turning the phone on so that the contacts touch. I think that it may have been due to constant charging (may be wrong) So, yes, there is a possibility that your battery is getting 'old'.

I don't use data connection and use same apps like in GB. I did check and deep sleep works, wakelocks test will have to wait till tomorrow when I charge battery fully^^

Hmm I am glad to hear you've got similar power drain during night. Perhaps ICS is really more powerhungry than GB. I will test in Better battery app for wakelocks occurence.
I don't know how and in what way the battery monitor reliable can be, especially when I see hourly battery drain. Generally sometimes I see power drain at 0.1-0.2%, sometimes at 1% but in same time CPU was doing nothing... (deep sleep).
I found Camera eats a lot of power compared to GB... or it is only my imagination
