Some of the apps, such as Ant, use a lot of my ram and it kills the battery
You're confusing two things. With Linux (Android is a version of Linux), unused RAM is wasted RAM. Android will always fill your RAM as much as possible. That doesn't use more or less battery. Every bit in your RAM is either a 0 or a 1 - whether they spell out the code of an app or they're random garbage has no effect on battery usage. (That's for an app sitting in RAM, not one that's running and using hardware. To Android, they're two totally different things. RAM is being used as a fast storage area in this case.)
What does, though, is having to load a program into RAM that was there a minute ago, and is needed now, but was killed by a user who thought that killing apps that aren't being used at the moment saves battery. It shortens the time between charges significantly.

making the life poor. I've tried removing the bloat with titanium back up and other app removal methods and none work. Titanium back up tells me "failed to find system APK" each time i try.
That would mean that the app you're trying to freeze was improperly uninstalled, or corrupted in some other way. (
Uninstalling system apps, OTOH, isn't just a bad idea, it's slitting your phone's wrists - with a chainsaw. Some system apps depend on code in other system apps to run. Uninstalling what you may think is bloat may disable your phone. At least a frozen app [it's still there, it just can't run] can be unfrozen.)
It did this to my on Some of my old LG's too. Anyone know what to do?
Pretty much ... just let the phone do its thing. Android does its thing pretty well all by itself.
If you need better battery life, turn off all functions you're not using - wifi, GPS, Bluetooth, even data. Set the screen to blank after 5 seconds. (Use an app like Stay Alive to keep the screen alive when you're plugged into power.) The screen uses a large part of the power usage of a phone.
I can get over 3 days on a single charge on my Note 3 with average use (if you really need proof, I'll waste the space on the forum and upload a screenshot of 4 days, 18 hours and some minutes, with 16% charge left [I cheated - I just peeked at it]), and I never bother to look at what's in RAM, the phone isn't rooted (I've seen some reports that battery usage skyrockets after rooting) and nothing is frozen. (I have all the S-crap that I can get to turned off - it's annoying to have your phone tell you that it'll check the internet for "sugar" during dinner.) Granted, my "average use" may not be yours - I don't spend hours streaming Youtube videos, or talking on the phone for hours. It's my PHONE. I write my reports on my laptop. (With my fingers, writing reports on a phone means carrying both a phone and a full-size keyboard - in 2013 I don't call that portable. [My Panasonic Sr. Partner was considered 'portable' - that meant that one man could lift it off the ground without incurring medical damage.])
But even "more-than-MY-average" usage should give you a full day's use on a single charge.
Oh, it may be too late but it can't hurt. Fully charge the battery (use the charger and the original cable, not a USB port on a computer - it's much faster and it's better for the battery). Unplug the charger when the phone tells you to and use it normally (whatever "normally" is for you - all the radios on, flash fully on, it doesn't matter, you just want to discharge the battery) - without charging it - until the phone tells you to plug it in. Turn the phone off and plug it into the charger and let it charge fully - don't turn it on until it's fully charged. Do that 3 times. Then you can charge it whenever you like.
Even though you've been using the phone for a while, depending on your charging cycle the battery may still not be fully conditioned. The "3 full cycles" will condition it. (I still have 10 year old batteries that give me full charge times.) Draining power from an unconditioned battery isn't all that good for it.
When I buy a new phone, if it's not something that can run on the charger with no battery installed, I insist that they set the phone up on their battery, or replace the battery after setting it up. I don't want a partially damaged battery with a new phone. Some engineers disagree with that, and I don't know enough chemistry to give a cogent argument [I'm an EE, not a CE], but I know from many years of experience that either it works, or randomness works differently with me than with everyone else.
