    I just bought a used galaxy s2 (international version), off eBay along with a new 'genuine' Samsung battery, to replace my trustworthy 3 years old HTC sensation, I lost. I upgraded the phone to 4.1 and performed a factory reset, as recommended by many users of this forum. I then calibrated the battery, by taking it out of the device after charging, with the device off. I am still only getting 6 hours of 'weekend' usage and approx. 11 hours of light 'weekday' usage. Any recommendations? This is a great phone, even though it is 2 years old, apart from this issue.

    Welcome to the forums.
    Since batteries are pretty cheap, I would try another one.
    Although calibrating the battery isn't needed.

    I get the same battery life on both batteries, so trying another one is pretty much out of the question... What about system tweaks? Would rooting help? Is there a touchwiz custom ROM that has better battery life? I have disabled a few Samsung apps, which seems to have helped, although I still have trouble making it through the day without topping it up, which is quite unpractical!

    Clearing cache in recovery may help.

    No noticeable improvement after the cache clear... Any other suggestions?

    Do you leave Bluetooth and WiFi on all the time? Brightness level?

    Bluetooth and WiFi are off ( on 3g most of the day. Brightness is down to the minimum setting. I guess I'll have to live with recharging my battery twice a day... Thanks for the advice anyways

    It may be you have a weak cell signal too.

    So I've found that the battery drain stops when Mobile Internet & Wi-Fi are off (I managed to get 10 hours with 25% drain, turning on 3g a few times to check Messenger)! Is there any way I could reduce the drain the 3G has on the battery? My network signal is not bad (I live in the tcity centre)!
    Thanks for the advice!
