thats what i was rooting for was for the hotspot and bloatware but must of all was to get better battery life. what i wanted to know is battery life is suppost to be better after you root, i just wanted to be pointed in the right direction for that i.e. how to get rid of some of the bloatware and suggestion on what to run to get better battery life thats all. THANKS to anyone that can help
Try SetCPU. You can buy it off the market, or do some searches for joining XDA and picking it up as an XDA member. You can tinker with your profile settings to get bettery life out of your stock ROM.
Or if you don't want to go through the hassle (which I didn't)... you can try a custom ROM that has battery mods, in addition to other customizations. Here are two Sense based ROMs which I have tried that have good battery life:
Myn's warm 2.2 (which RLS5 is coming out tonight, based on 3.70) uses the colinph battery mod. I got some great battery life with that ROM. Don't use setCPU with the default kernel, because it does not run in tandem with colinph. The default kernel and stuff has all the mods out of the box, just flash the ROM, flash the mods you want (there's a bunch) and roll with it. You can experiment with different kernels later.
Evio 1.76b has an undervolted kernel built into it. You can then also download setCPU (which is not packaged with the ROM) to get additional savings... the ROM has setCPU profiles already built in, so just flash the rom, install setCPU, run setCPU and ensure it has root access and it should have all the profile settings the ROM was designed for.
I also used CM6 with setCPU. Inherently, since this ROM runs faster and uses less resources it feels like (seat of my pants measurement) that it is more power efficient. Coupled with setCPU, I had good battery life here. Cyanogen, remember, is completely AOSP based and has zero HTC Sense ported into it... and will never have. Wimax/4G is in alpha stage at the moment.
You can find all these ROMs on their respective pages in XDA under the Evo / Supersonic android development forum. With those above ROMs, I was getting around 16 hours battery life with gtalk running and with a constant 24/7 flow of work email. With gtalk turned off, I usually get like 24-40 hours depending on usage. YMMV.
I don't agree inherently that rooting gives you better battery life. Rooting allows you to apply mods, or run different software that is more efficient, but to say that rooting = better battery life is a misnomer. Functionally, yes, for best battery life... must root and apply mods/remove bloat/try new ROMs. =)
