That link is for Motorola droid. This is the Eris forum. Any update from HTC or Verizon expected? Also, how do u know if background apps are running?
Not sure I agree with Cereal. I don't know why a specific UI would be a battery hog. I too experienced horrible battery life at first. Then I followed a few steps detailed on other forums and things got better.
1 - For three nights in a row, fully discharge and then charge your battery up.
2 - Do not use Visual Voicemail; it doesn't allow your phone to sleep. Likewise for the third-party app YouMail. Do not install or use it.
3 - Check your Awake Time frequently (at least at first). If you see something apporaching 100%, some program or another is not allowing your phone to go into sleep mode.
4 - Be judicious with your use of Bluetooth, GPS and Wifi. I don't have Mobile Network turned off and I am still getting reasonable battery life.
5 - Under the Mobile Network settings, uncheck the setting for "Enable Always-On Mobile". I think this shuts down mobile network (which includes push email, for example) while the phone is sleeping.
Report back to us in a week and let us know how everything goes.
Yeah, all those pretty animations are using resources (don't get me wrong though, I've seen examples on youtube and man I wish they had a UI like that on the droid). They even modified the flip clock so it doesn't "flip" anymore to save memory, cut down resources and etc...It is well advised to not do #1, once in a while but never 3 nights in a row.
Secondly yes a UI can be more of a resource hog then not having it on there. Sense UI enables more features and effects then the normal UI. The reason that people like it so much is also the reason why it runs down a battery faster.
New extended life battery comes out jan. 10 2010. I cant remember the name of the company but it starts with an s. Supposedly it fits in the standard battery housing so it doesnt thicken the phone. From the website it goes for about 50$. I dont know if thats worth it, ive never bought an ext. Life battery
