so i rotoed my phone last night and now my battery life is terrible. i used unrevoked3 and have not added any roms. i did download titanium backup and wireless tether from the market. it doesn't look like anything is using phone needlessly, nothing with long process times or keeping phone from sleeping. i have noticed that phone seems faster than before. i am using battery indicator and just using my browser for a few minutes my battery dropped from 96% to 91%. i guess i'm asking is this normal or do i need to look deeper for the cause of this? oh yeah, i don't use my phone much during the day while working but i have had to charge it twice today just to make it through the day. thanks for any help anybody can give.
 
Same here. Used unrevoked3. No other changes. Battery life is terrible now. For those of you who say one has nothing to do with the other.....you are wrong. This is the second time I have rooted since having the phone with the same result. Once with 2.1 and now with 2.2

I'm running CyanogenMod 6.1 (stable with invisiblek #18 kernel and BatteryLeft right now reports a 68 hour battery life. I use the phone lightly and mostly as an mp3 player (siriusxm, last.fm and mixzing music player) and for emails. This morning after 24 hours of use I was still at 70% battery.

With the Virtuous 3.1 ROM and heyitslou's #5 kernel I was able to get 33 hours of battery life.

silentronin..this is normal for a incredible whether rooted or not. It has to do with the way the software charges/reads battery capacity. The 10% from 90-100 usually burns very quickly. I just rooted and put miui on for a ROM. I have seen at least 6-7 more hours while using the phone heavily. If i dont use it much during the day im seeing up around 15 hours of total battery use.

Reset the battery settings; the Dinc post-root will apply the old readings and miscalculate available charge.

I did that using Battery Left and suddenly saw a marked improvement.

Incidentally, rooting alone will not necessarily improve battery life. Installing a ROM that doesn't have the Verizon-always-on-bloatware will help, as will installing a different kernel, or running apps like SetCPU which only run on rooted Dincs and which will underclock the unit when it is not in use.

I get close to 24 hours battery life running Virtuous ROM 3.1 with stock kernel and letting SetCPU underclock. The Battery Left widget is finally figuring out how much charge I really have left.

*UPDATE* I've since flashed HeyIt'sLou's kernels 3, 4 and currently running 7. I've pretty much disabled SetCPU except for when I'm charging (so the kernel doesn't underclock while the phone is doing Titanium backups). Battery life is even better, even with the stock battery.

I get over 2 days of normal use with Warm Two Point Two and Lou's #4 Kernel. I'd try flashing a ROM/Kernel combo that is known to improve battery life.

rooting doesn't change how your phone operates and will have no effect on battery life. An analogy would be turning an account on a windows laptop from limited to administrator... Your just giving yourself extra permissions, no changes are made to the phone.


Yes, but that is not all you are doing.
various things are changed also.
For example a superuser app is installed and starts to monitor permissions.
I think my facebook syncing was turned back on and news was turned back on.
I have now turned those back off and it seems that things are going a littel better. I am going to start reinstalling apps that are for rooted phone and see if they make a difference.

I noticed you said you DL'ed a wireless tethering app. I'm fairly new to the dinc, but i'm assuming that's the app that lets you "hotspot" your mobile. If that's the case, that will likely own battery life if you don't make sure it's turned off. Also, if you give yourself admin access to anything, you are automatically giving the system permission to run various apps that it couldn't before. Maybe make sure you're only running the apps and features you want to run.
