Default Bizarre battery issue - help?! Please!!!

Hey all,

I donít know if anybody could help me but I need a little advice.

In the last two days, my battery has gone from giving me 20+ hours to conking out at about 15/16 hours.

Hereís what I did:
Installed Lookout Mobile Security (which says it uses pretty much no battery as it lays dormant unless Ďcalled uponí)
Installed WP Clock live wallpaper (which I then found out DOES drain battery on some launchers)
Installed a couple of other clock widgets which have been uninstalled now apart from 'clean clock' which I'm using.

Installed a widget that updates info once a day. Have removed it now.


So, I stopped using WP Clock Live Wallpaper and froze it using titanium but my battery is still a bit crazy. I have not changed any settings in the display or syncing or anything like that.

My battery says display and Android OS are the big users of juice (before the last couple of days, Android OS was minimal and display was the big hitter Ė now, theyíre almost equal.)

So Iíve now installed WP clock as I figured even if it is not being used, it may still be draining battery. Iíve also installed Watchdog to monitor apps.

After installing Watchdog, my battery was 36%. I pulled it and replaced it to reset the phone and immediately when it was turned on, it read 19%. Iím now drip charging it from my USB port at work and it has taken not very long to go from 19% back to 36% (maybe half an hour) which makes me think the battery readings are all over the place.

Iím running a Samsung Galaxy S2 with the baseband version I9100XXKE7 which I think is the one that was on there by default (I did root it).

What do you think? Is this one of the situations where all that calibration stuff is necessary or am I jumping the gun?

Help and advice would be greatly appreciated.

Thanks in advance.

Install BetterBatteryStats from the Market and set its defaults to "Partial wakelocks" and "Since charged". Charge the handset fully, reboot then use as normal. After a few hours open BetterBatteryStats and it will show any apps preventing deep-sleep, the most likely cause of unusual drain.

Thanks for that. Is that different to Watchdog in terms of what it does or should I run them both simultaneously?

Sorry to be a numpty but what's deep sleep as opposed to the normal screen-off type sleep?

Thanks a lot

Running both won't cause any problems. BBS simply presents some of Android's 'hidden' data to the user.

When idle the CPU should clock down to a minimum setting, reduce voltage and basically go into 'life support'. Processes running in the background will require processor activity, obviously disturbing this (by generating a wakelock), but for the majority of the time the handset sits idle it should be in this state. BBS will reveal if anything is causing excessive wakelocks and thus effectively preventing the CPU from entering the power-saving mode. You can already get an idea from the "Awake" history under the battery usage graph - BBS expands on that by going into more detail.

I hope that made some sort of sense?
