Display eating up battery - please advise
I have been trying to extend the battery for my HTC Inspire 4G by following the tips on this forum. But I don't know what to do about the display (4.3" LCD screen), other than decreasing the brightness (set at 10%).
The battery usually dies in 5-6 hours of moderate usage and every time the culprit is Display (consumes 80-90 % of the battery).
Any thoughts / advise on this issue?
Are there any battery-friendly wallpapers or themes I can use ? Will rooting the phone make a huge difference?

Keep that brightness down, turn off auto brightness, and lock your phone, don't let it time out, unless you have some insanely low timeout increment. Don't use live wallpapers.
I went from 6 hours to 11 keeping my brightness to what I needed to see.
EDIT: If you really really really need to be out of reach of a power source for a while I reccommend considering an extended battery, might add 2-4 hours of life per charge, as well as just extra batteries to carry around, along with another charger such as: http://www.duracell.com/en-US/produc...b-charger.jspx for moderate use or: http://www.duracell.com/en-US/produc...b-charger.jspx for sweet holy hell use.

I got one of these from Amazon. It will give you 2 full recharges from dead. Definitely worth it if you have no other charging options.

The original poster was getting 5-6 hours of charge out of their 1230 mAh battery, lets assume 5.5 hours is a good number.
5.5 * 60 = 330 minutes
330 minutes/1230 mAh = 0.2682926829268293 minutes per mAh.
Multiply that by 70 (the difference in mAh with the extended battery) and you get: 18.78048780487805 extra minutes of power.
Obviously my theory is wrong or the battery doesn't add that much juice. (My previous 2-3 hours was from anecdotal evidence).

Also, while were talking about batteries, is it bad for the battery to charge it when it isn't dead or near dying? I heard that you only want to charge it when the powers almost completely drained. And is it bad to unplug it and use it before its fully charged?

If you're using your phone moderately and only getting that much usage something else is wrong. Double check all your apps you downloaded and the ones that came stock. Check to see if they're not connecting to the internet constantly. I leave my display at right under 50% and no auto dim and mine lasts all day. I unplug mine at about 6:30 in the morning and I still have about 50 or more by 8:00

Thank you all for your advice.
I guess an external charger is the only feasible solution to the battery issue, since I've tried all other software recommendations. So now the problem becomes which portable charger to get? Both the duracell and trent chargers have good reviews, but trent seems to offer more mAh for the same price (2000mAh vs 5000mAh).
For a cheap option, the Motorola P790 ($10 ; 1700mAh) seems to be a good bet. Any thoughts on it?

Other suggestions would be most welcome.
