[HTC Amaze 4G] seansk:
I apologize for comming off angry. Something pissed me off today and got 3 hours of sleep.

Honestly I havn't flashed all the roms. Here's how could explain this to you better. AOSP is the pure google version of android...usually google flaship phones have these such as the nexus one, the nexus S series, and galaxy nexus. I believe the G2X also has a pure google version of android.

Each company such as samsung or HTC customizes these roms to their liking and puts it on their phone...sometimes they add features, widegers, eye candy, extra settings. HTC calls their User interface (UI) that they use Sense, samsung calls theirs touchwiz and so on.

Senseless rom takes some parts of sense out of sense and leaves some parts in I believe, this is what I remember from reading that thread. In the thread it usually tells you the major things that have been taken out, and things that have been put in

for you screen bleed solution the only way I have seen is to turn down or off the button lights using "screen filter" from the market.

4G is one of the biggest drains on the newer phones. I have juice defender Ultimate but stopped using it. under normal stock settings in juice defender when you turn off the screen it turns off both wifi and wireless data...so you could only basically get phone calls, sms, and mms. Things such as Gmail push, facebook updates, google voice updates etc will not be allowed while phone is off...is why I stopped using it. You could change settings to turn data on during screen off or, turn wifi on, etc. but that would defeat the purpose of the program, turning off wifi and data network is the biggest things that let juice defender save battery.

Biggest drains again are, 4g data, wifi, and screen. You can tweak these under the wireless and network settings.

Technically you could remove the contact and dialer app, titanium backup will let you do this. But I warn you against doing this I believe since parts of it are integrated into the rom. freezing apps is a much better idea. You could download dialers from the market currently I use excontacts with ICS them on it. You could other dialers. But I believe that actual contact editing and contacts cannot be completely removed from sense, you would have to flash a different rom to get the AOSP dialer and contacts, or other ones.

My understanding of lithium ion batteries is that they have NO Memory unlike older batteries, It is pointless to charge the battery for 12 hours the first time...there is no trickle charge on lithium ions. In my own honest opinion/experience battery statistics make no difference in battery life, but others can correct me if I am wrong, this is where people say calibration makes a difference, I really don't know. It's also very hard to do a controlled test of a battery, since phone uses different things at different times, network connections, wifi. all that stuff.

P.S. updating to the newest update from HTC on my phone solved my overheat and battery issues.

P.S.S switching to other launchers will take away you ability to use sense widgets and customizations, since they are part of the sense launcher.
