Dreadful battery life

---

I can't figure out whats wrong, all I know is battery life is dire. I got a HTC Mozart before Christmas, I would take it off the charger at 6am, before I even went out the door battery life had dropped. To cut a long story short it turned of shortly after lunch time and that is in airplane mode, I did listen to some music but even so an iphone in airplane mode listening to music will last a good couple of days easily if not longer, not 7-8 hrs. So I sent my phone back.

Just this week I got another HTC Mozart as I thought maybe the first one was faulty, and I really like the windows 7 platform and the Mozart has an awesum camera but it is exactly the same as the first, the phone dies soon after lunch time, I have never seen such poor battery life in a phone. My old HTC Desire with all turned on at least made it to 6pm and my previous iPhone made it right the way through to 11pm with all turned on so i can't figure out whats wrong with this phone.

Anyone any ideas?

I should add 3G is of as I don't have any coverage. No push notifications and also in airplane 90% of the day, only turned on occasionally to check email.

Here's setup that i got from HTC Team, :

System tab:
Wi-Fi: off
Bluetooth: off
Email & accounts > Download new content: manually (for all email accounts like Windows Live, Yahoo and Gmail)
Lock & wallpaper > Screen time-out: 30 sec
Location > Location services: off
Brightness > Automatically adjust: off, Level: low
Find my phone > off (both options unchecked)
Feedback > Disabled
Wallpaper > Set for darker color
3G connection > On only when browsing or downloading

..... i'm having the same problem previously... 3 hours standby and the batt drained...
so, i get this setup... with moderate usage, it can last 1.5 - 2 days... hardcore usage : 6 hours - 1 day [depends on what you're using]

Right ok I am already doing most of them, will try the rest and see what happens

owh ya...
+ my own setting :

speech > audio confirmation > off
ease of access > off [i'm not sure this is for what, i just simply turn it off..lol ]
keyboard > off the text suggestion
facebook > only tick for "shake to refresh" ; updating- never

that's all.. good luck [^_^]

i left mine stock, and the battery isnt great... but its not THAT bad....

Yeah its strange that about 5 mins after unplugging it from charge it looses a tiny bar...

But after that its ok for me, and i play music on it through my car for 4 hours a day and even after that its only just above half...

I'm a fairly heavy user with around 4+ hours of browsing, 1 hour of music and email retrieving every hour but I always make it through a full day. If I don't touch the internet and just stick to sms + calls I have managed to make it through 2 full days.

The Mozart does have a fairly small battery compared to some other smartphones available but Mugen do sell an higher capacity battery which I have contemplated buying. You can read more about it in this thread here.
