So, there has been a lot of carping on this forum about performance. Be it battery, speed, lag, etc., a lot of people have issues with the phone. I will admit, I am one of them. Initially I had battery issues. My battery seems to be pretty (wouldn't say very) robust now. I can get a full day with HEAVY use (GPS on, BT on and connected for 30 plus minutes of calls, lots of browsing, FB, camera, photo uploads, etc.) So inspired by this thread, and especially ErisUser's post, I decided to go back and look at my phone more closely. I had posted in another thread that I finally had figured out that the main issue causing lag on my phone was Sense. Sense has been running terribly: re-booting, freezing, taking FOREVER to load, and generally slowing the phone really down. Reverting to the stock "Home" application eliminated all of this, at the cost of my HTC widgets, and some of the ease of the Sense operation. I've been running this way since Saturday, and the phone has been great. I've checked back with Sense a couple of times, and it was just laggy and slow. Note, that I am doing all the correct maintenance: task killing, cache clearing, etc. So this last thread got me thinking: the phone hadn't always been this way. I never would have bought it if it were running this slow. So the problem, more than likely, was something that was interfering with Sense, not Sense itself. I made a list of Apps I had installed: Advanced Task Manager AK Notepad Amazon Astro File Manager Backgrounds Barcode Scanner Dolphin BrowserEar EBuddy Facebook Handcent Key Ring Open Sudoku Shop Savvy Spare Parts Sports Tap Startup Auditor The Weather Channel Unit Converter Retro Clock Widget (used with Home) Android Agenda Widget Then I thought: what could be screwing with Sense? I have had pretty much all of the Task Managers: Task Panel, Advanced Task Mgr, Advanced Task Killer, Auto Task Killer, etc. So I figured, that probably wasn't it. Especially since I always have ATK kill itself. But Startup Auditor. Now there could be a possibility. So I decided to uninstall AK Notebook, the Retro Clock widget, and Startup Auditor. I then re-activated Sense. I did not restart the phone. My phone was back. Speed was blazing fast again, even faster than with Home running. I could not believe the difference. Dialer, Facebook, Browser, EVERYTHING was fast again. Now, I am sure that there are people using Startup Auditor with success. And I have to say that I have had apps "go bad" on me before (Chomps SMS was one of them). But for me, it was the culprit. So here's my thought, and I'm sure it's been said before, but I'm sure that some people new to Android (me, included) could stand to give it some thought. Android is an operating system, like WinMobile, Blackberry, etc. It operates on a LOT of platforms. In addition, HTC phones overlay another GUI over-top of Android. So right there, there are a lot of variables to performance. Now, add in apps. Each app has the potential to screw something up. Add to that the fact that the apps are open source and go through nothing more than peer / market testing and again run on multiple platforms, and you have a recipe for issues. I've said it before, and I'll say it again, Android phones are for tweakers. I've tweaked my phone a LOT and am still getting to know the ins and outs of how it works. I've tweaked a lot of settings, but I'm sure that I haven't scratched the surface. I can only imagine what can be done with Root access....I'm not sure I want to know. So, if you're having issues, have faith, think about how your phone was in the beginning, or how others run. Take measurements of program usage, keep notes, figure out what's wrong. Chances are, you'll figure it out. All I can say is, I'm glad to have my phone back!! P.S. One other thing I did, that helped a lot. I got my wife an iPod touch for Christmas. It's WiFi enabled, so I have been able to set up mail, etc. In typing, I noticed that I LOVED the keyboard. But I also noticed...no haptic feedback while typing. Hmmm. So I turned it off on the Eris. Holy crap, I type SO much faster now. And with better accuracy too, as I can type much closer to my "natural" typing speed, so I tend to make less errors. I don't think the keypad has become any more sensitive, just my fingers more accurate!!!
