I found out the hard way that task killer was a big waste of time and effort. Doesnt improve crap (at least for my phone). Even when used every 10 mins my battery drained the same, it probably drains more using it due to restarting programs etc.
battery life is a bigggggggg issue from this phone but what do you expect from such a powerful device, just learn to manage it depending on needs.
Honestly if your a juice head like me, on a typical work day 5-5 with overtime I need to charge the phone by mid day.
This is with everything on and constant usage every 10-30 mins checking email, social apps, banks, etc..
I have push on for exchange, yahoo, and gmail. Most motorola and android widgets such as weather, messaging, twitter, social apps/updator i.e aim, facebook, and myspace, dictionary widget (constant search for new words), urban dictionary and more.
Gps and blutooth is on as well. I never mess with it. Wireless network on using company wireless. And 3g while I'm out of the office. By mid day I am around 10-30% battery left with phone already connected to the charger. Cant use this phone with the usb either (sucks I know). This is with 1-2 minor trips to the coffee shop, minor stop at starbucks and/or office depot for purchases.
I dont mind the charging since I have three chargers, yes 3! 1 at home, 1 in car, and one at work. And I repeat I don't mind the charging at all because I am a heavy user of the phone and I absolutely love this phone coming from crappy at&t iphone.
However, when Im off work saturdays and sundays, 1 charge will easily last the whole day. I always have the screen brightness on the lowest (not auto). This has never been an issue for me and I can see the screen clear enough in the sun and indoors in direct light. I think this saves tons of battery.
Also I turn off background data unless I need something from the market place (Im pretty sure this helps as well), On battery manager I put it to the lowest. I also turn off push and fetch for all emails as I can fetch manually on weekends when the phone isnt that important to me other than for text and email. wifi off 100%. Bluetooth and gps only enabled if needed such as driving to the closest store and/or receiving a call while driving where I know Ill be on the phone for awhile. With all these changes, they really do help improve the battery performance and I can get a full days worth this way from morning to night.
I was an avid iphone user for over 2 years on at&t and I can finally say the android phone was well worth the change. I do miss the look of the iphone with slightly better battery life and the fact that I can be using the internet while talking to another person however those advantages arent enough for me to go back.
