    Hi, I am using a Lumia 720 since 3 months now.
    But from past 2-3 Weeks it is giving me serious battery back-up issues.
    I am getting only 9-10 hours of backup on normal usage of 3G and 2-3 calls and whatsapp, and battery drains fast even when not using the phone for internet.
    I donot play any games on the phone as well.
    I have recently performed a Hard Rest on my phone but saw no change in the battery performance.

    Would appreciate any solutions to rectify this issue.

    After the Hard-Reset what programs do you install after that? If you getting this type of battery drain with only the default applications installed I would say that there is something wrong with the battery then?

    By "Hard Reset" do you mean you reset to factory defaults and then set up your phone from scratch? Or do you mean you held down Vol Down + Power button for 15 secs - this is a 'soft' reset?

    Try uninstalling whatsapp and see if your battery will improve. I saw on the other threads that whatsapp is a battery hog app.

    Hello,

    Sorry for late replying as was busy with office work.

    @OzRob I had performed the hard reset i.e. Factory Reset.
    @PulseRider I installed most of the apps which I was using previously.
    @CharlieBoy1894 The problem was not with WhatsApp

    But I found a strange thing after this issue.
    after Hard Resetting my phone, from the 2nd day it was giving me a normal battery performace again i.e. 25-27 hours.

    What I noticed was that when my phone was giving the battery back-up properly, my Google Mail account which was added in my phone was syncing properly.
    But recently from yesterday, I am seeing the similar trend of the battery draining out quickly and the strange thing I saw that my Google mail was not synced from yesterday night, as it was showing mails from the previous day, but the Google Mail app was continuously syncing....so it was using up the battery on a continuous basis.

    Today I unlinked my Google Mail Account from my phone and now I am getting proper battery backup, after doing this I saw what were the reasons that the mails were not syncing in the Google Mail App.
    I saw that the clock of the phone was not up to date because of a soft reset, I changed the clock timings and tried syncing again, but the problem persisted and I had to unlink my account once again.

    So Now the reason of the problem is found that is the " Synchronization of the Google Mail App ", But I am not able to find a solution for this problem.

    Any help will be appreciated.

    Thanks and Regards

    Then it sounds like you DON'T have a problem - 9 hours screen time is gonna suck the battery dry pretty quick. I think getting 10 to 11 hours is actually pretty good under those circumstances.

    Did you check battery saver which app uses the most.
    Did you install a new app or pinned a website on your start screen?

    I also faced the same problem since a last week. the recent windows update(fix) ruined the phone like anything.
