[Q] JuiceDefender?!?!

I RARELY buy apps. Probably only bought 3 in total but how many people would recommend JuiceDefender Ultimate Juice? Does it really help with battery life? Is it great?

some ppl will probly argue tho it did help lil on my 2.2 rom but the gin roms jd has real issues the brightness goes up and down dosent allow u to install anything until u uninstall jd, i tried to stop it from running and still no go so id save your money

It work a little ..but like the guy said save ur cash...
funnie evo

I'm on cm7 and I bought UJ finally and it's pretty good. Makes my phone last the whole day. Granted I am a moderate user but from 4AM to 12AM is pretty good.

I use sense roms and i see a big enough difference with JD Ultimate for the few bucks it costs..i get close to double my regular battery usage with it..there is ways to get it without paying if u are into that kind of stuff

i'd try normal juicedefender first. if you like it, then review what features you will get from ultimate. if you think it's worth it, then buy on in. if not, then don't.
btw, in my experiance, letting it toggle my 4g actually lost me battery.

My experience it was ok. I got it for the sense 2.1 rom due to the brightness issues. I had to unistall it because it was making my connectivity act up. My data wouldn't start back up on wake sometimes. Overall it wasn't saving me a dramatic amount either.
In all fairness I didn't customize it. Just used normal or aggressive default.

SetCPU
If you're really gonna spend some money on an app SetCPU is the way to go for battery life (Assuming you're rooted). This way you have a customizable governor on your processor and you can tell it how fast to run. Unless you've already done this in which case sorry. I get at least a good two days out of my battery on almost all the roms I run and I flash a lot, Letting it die completely when the screen is off does a tremendous job & really you don't need it to run over 700 mhz for most things. Give it a try, the trick is setting the profiles. Use on demand for your scaling then set accordingly, keep in mind you need to set the most important profiles such as temperature and screen off as your 100 or 99 level profiles. You'll get the hang of it, but as I said if you already use it then this was a giant waste of typing
P.S. if running the Stock HTC Kernel you have to disable perflock in order for the profiles to work. Main tab, menu, perflock disabler.

First of all, the super awesome setcpu developer posted it on the forum for free, so you don't really need to buy from market. Second, the smart ass governer can do this all automatically. Finally, juice defender still works better for me.

I use Tasker from the Market, creating profiles such as turning off data when screen is off and data on when screen is on (doesn't affect voice calls or SMS/MMS). Also, I use Autokiller Memory Manager (not a task killer). I can get from 17 hours on normal use to 31 hours with light to moderate use. As I write this, I'm at 88% battery left after 5 hours off the charger.

What exactly do the app do?

On and off system lag. Is it related the amount of apps installed?

I am currently running mikG 2.45 more freedom. Titanium backup loaded 335 Apps, which include system apps. I am thinking the maybe 200+ apps I have installed are the reason for the on and off lag.
Sent from my PC36100 using Tapatalk

Apps maybe be paying apart in it but you say your running "more freedom" try running the stock freedom not the more or less or extreme or whatever he calls them. The undervolting may be limiting your processor. Also use set CPU and try to overclock a little. Im running synergy rls1 with stock freedom overclocked up to 1152 smooth as a whistle and battery is through the roof. try stock freedom and if that dont work pm me and ill help u out more if needed

Overclocking doesn't really show a noticeable impact in my experience. Only if you are playing a CPU intensive game that pins your CPU at 100% then it drains slightly faster not to bad tho. Also if you use the "interactive x" governor it manages the cpu's frequencys to try to keep them as low as possible so you only using enough to do a task instead of going 100% for something that doesn't need that much power. It also keep the CPU at the lowest frequency you allow it to be when you shut off the screen. So if you set your Max to 1152 and min to 245 for example. When you shut off the screen it will stay at 245 and not jump around. That tremendously helps battery. It about 8p.m. here and i have had ghis on since 7 a.m. and I'm at about 30% and that's with quite a few text, 2 - 5minute calls, about 20 minutes of games, and an hour of music. The only bad thing about overclocking is that if you go overclock to far for to long you can fry your phone. But ive been running 1152 for about 6 months and perfectly fine so i figure that's pretty good. If u have more questions or need help pm me
Edit: i forgot i also had about 20 min of internet/xda browsing on wifi and the past 45min on 3g doing the same thing haha

(Q)I have a og evo and cant overclock it 1.2ghz.

I have a og evo I want to know why when I overclock to 1.2ghz it freezes my phone why does it do that ?
Sent from my Nocturnal 4G using xda premium

Each Evo is different. Some of them can't handle that high overclock, or can't be undervolted very low. Each one is different, each has its limits.
I don't understand the big deal with overclocking. It burns your battery faster. I personally underclock, with little to no lag and is good enough for my casual gaming needs

Mine doesn't like a clock much at all. I can get about 1.1 before it starts locking up but even then it hangs a lot. I honestly don't see a difference from 1.0 to 1.2. Get a decent rom, good kernel and try out the v6 script an I almost guarantee you will like that better.

Well for us to be able to help you, you would need to provide us with more details on how you are trying to accomplish this.

I use no frils cpu but have also tried setcpu and viperMOD I know that's the best way to overclock but is very confusing. Have any step by step instructions to of to 1.2 I know having higher voltages helps as well.

Overclocking is overrated. If you need to overclock for every day usage, then something is wrong - at least in my opinion. Resource intensive gaming is different, but you shouldn't need to overclock for browsing, texting, casual games, etc.
Try out the V6 Supercharger script. I'm not currently using it, but have in the past and it seemed to make my phone more snappy. A lot of people swear by it and it's a great script, definitely worth a shot. There are other things you can do to speed up your phone without overclocking. I'd try other options first since overclocking will chew through your battery. Increase the dalvik vm heap size, there are plenty of free apps on the market to help with this task. Uninstall apps you don't use, I'll bet that you never use some of the apps on your phone. Back them up with Titanium Backup and you can restore them if you ever need them again.
In case you didn't already know, the Evo can't overclock past 1.2, I'm not 100% sure why - it has something to do with the processor.

I never oc over 1075 and only when plugged in if i play a game I need to oc.for I just activate my charging profile and plug up and play 1.2 ghz is a good chance of doing serious.damage as these older scorpion processors get very very hot at that clock speed so they lock up to try and protect themselves from heat damage or they shut down the phone 1075 is as high as you should need to go for any games the evo can handle on the subpar gpu

I'm pretty sure viperMOD is more for undervolting than overclocking, which are not suppose to be combined together. I am running vipermod with max voltages - 50. Other nite was playing snes9x and was getting some lag with a game so I bumped max CPU up to 1.2. Phone went into a bootloop and had to superwipe and reflash everything. Don't know if its b/c vipermod + 1.2 CPU or just bumping up CPU. Didn't try it again.

You can overclock and undervolt together just fine. You just need to ensure that every frequency has a high enough voltage to run the processor at that step. My Evo is overclocked and undervolted just fine, although IIRC I can only push it up to 1.1 GHz . My tablet is 1ghz to 1.6ghz and is undervolted as well, though.

merge rls 2.0, iron monkey, Droid overclock because of the profiles options. I set up four profiles including one for temp. sometimes i'm underclocking and sometimes overclocking but only up to 1.19 to prevent freeze and boot loops. Only downside is right at open Droid overclock needs su permission but that is my choice since profile changes at open.
Very snappy afterwards.

When I had the 4G, I was never able to go above 1118, or somewhere around that. It would have freezing issues.
On my evo shift, I was able to do 1.7 gHz (compared to stock 800 mhz) ok. 1.6 pretty reliabily, and I could run 1.5 all day long. Some guys could do 1.9. It just depends on the phone.

Actually overclocking and undervolting is counter-productive. What you should do, is read carhaulers and ropodopes guide over at vaelepak. Its give some good useful info about how to set up a good aosp rom. I'm underclocked, undervolted, and still getting 1400+ benchmarks. Check it out bro. You'll love the results.

What? Overclocking and undervolting are two completely different things, and they aren't mutually exclusive. Unless you can provide a good reason as to why it's counter productive to do both, I don't buy that at all. Just checked my phone, my overclock requires an extra 25 mV for all three steps I've overclocked. 25mV isnt much, and it certainly isn't going to kill my battery that much faster.
Besides, the only time the CPU is going to be entering these high power modes is when it needs to do work, and it's better to do work as fast as possible to go back to sleep. Would you rather wake up, do a mundane task for 5 minutes, then go back to sleep or wake up, do a task at 2x the speed while only consuming 30-50% more energy, then going back to sleep after only 2.5 minutes?

First let me say I don't use viper mod or any voltage controlling mod.
On sense 3.0 roms such as mikg I over clock to 1152 and set the minimum to 384 and its smooth as butter. No problem and battery lasts all day.
On aosp however such as decks (I'm on it now) I underclock to 499 and leave the min at 254. Smooth as always and battery lasts forever.
Anything past 1152 is going to cause problems (at least in my experience) also the rom/kernel can effect how much you can overclock.

Its counter productive because it is giving less to something that needs more. (Don't take this post as me trying to be a ****. Just voicing how someone explained it to me a while ago)
Think of this as cars.
Lets say you have a nice fancy v8 mustang. Stock, everything is well, balanced.
If you start adding parts and get it pushing out 1000 horsepower (overclock) your most likely gonna need more feul (voltage) or at least stock amount flowing into the engine just to keep it running.
Now lets say you got that same 1000 horsepower gas destroying mustang and you start to lower the amount of gas flowing into the engine (undervolt (done in vipermod)) cylinders (CPU) wont get enough gas, it wont work, and your stuck going no where.
So if that made sense (did to me) then you can see why they are counter productive. Unless your using vipermod to overvolt (which idk if you can since I don't use it) then you can disregard this whole post

Your car analogy is completely irrelevant. You can look up the exact voltages that the CPU runs on at every frequency, *even when overclocking*. Overclocking an Evo 1ghz to 1.2ghz takes maybe a 5% bump in voltage, and that 5% extra power is only going to be used *when the CPU is running at max speed* (which is only when there is a lot of work to do), and even then, it's *still better to let the CPU run at max speed with a tiny bit more power consumption than to cap the CPU at a slower speed and make it work for even longer*. Intel calls it HUGI, Hurry Up and Get Idle.
I know what I'm talking about, and I wish people would stop trying to argue with me based off of second hand speculation. I do this for a living, after all. There is absolutely nothing wrong with overclocking and undervolting, and it's the best way to get the most battery life *and* performance out of your phone, period.

Hmm, *interesting*. I believe the best answer to the OP was covered rather well earlier. It's all about your rom/kernel/hardware combination. With all the variables to consider as relevant, your best bet is to experiment and find what works for your device. Don't check set on boot untill you are confident the set-up is stable. Higher is not always better with overclocking. My device runs blazingly well underclocked @768max. Gets insanely great battery @499max. However my quadrants are better @ 1036 than at 1190.
Great thing about android is you can experiment and learn through trial and error.

Then why are you asking with help with overclocking? Your trouble lies in syncs or an errant app. Set your syncs to manual and uninstall any you don't use like Google + or Facebook or stuff like that. Get something like Betterbatterystats to see what might be using your battery. Also get Memory Booster Lite and use the task killer to see what apps are sitting in memory. Also get CPUspy to make sure your phone is going into deep sleep when not in use and not on charge.

Over-clocking will kill your battery faster. I think you meant to ask about undervolting? That could save you battery life. But, before all that, I'd check for errant apps that are running like the previous post suggested. Also, get rid of widgets, etc.

I honestly would not advise overclocking. Everyone has their own opinions of it, and it is ok, that is, if you know what your doing. Sometimes people get the wrong impression that anyone can overclock their phone, which is entirely untrue. Unless you constantly want to worry about tweaking voltages, monitoring temperature, worry about frying your CPU and voiding your warranty, i would just stick with what you have.
There are PLENTY of roms out there that will boost your speed significantly to the point of never needing to overclock, unless your just trying to impress your friends.
I strongly suggest starskyrom, which you can find here.
If your mind is still set on overclocking, go to youtube and search samsung epic overclock. Look specifically for videos made by qbking.
I would use the Samurai kernels, and I would NEVER go beyond 1.2 ghz for everday use. Its ok to bump it up to 1.3+ when your showing off, or need some power for a short period of time.
Good luck, and remember, overclocking has its rewards AND its risks. The question you need to ask yourself is a $500.00 phone worth risking for a barely noticeable amount of performance increase.

I'm sorry for misunderstood the use of O/C & U/V, my phone yesterday leave me without batt. & get tired of it. I've used Odin to go back stock and actually stay that way but find it kinda boring =/...
I will check the Starsky Rom right now, I'll search for more info. about the U/V uses which is the one I'm interested.
Thank you all for having the time & patience to answer, even recommend me some app's & rom's, I'm very thankful to you all =)!

It's actually pretty simple. First off you need a kernel that allows undervolting. Secondly you need an application like an NSTools or STweaks however with STweaks the kernel has to support that application. Once you get in there and it shows your frequencies its going to show your millivolts as in mV. Take for example let's just say that you're 1.6GHz frequency is @1100mV you can take it down to 1075mV. And after make sure its stable if so continue to undervolt and so on and so forth. Now again those aren't real numbers. There just an example for you. Now there is a thing called overvolting which is essentially only used when you have a frequency that is unstable.

Some tips:
Don't make any changes to roms, mods, kernels, etc while testing undervolting. You don't want to introduce other variables during this phase.
Go by steps of -25mV to be conservative. Do -50mV if you want to be aggressive in your testing.
You know if you've undervolted too much if you start noticing laggyness, UI studdering, random reboots, and other unexplained problems. This is why you shouldn't make other changes during the evaluation, since you wouldn't know what caused the problem.
You will need more voltage at higher MHz. It's not uncommon to undervolt more at the lower frequencies.
Once you find a safe undervolt settings, it can be a baseline for other kernels/roms. You'll still need to verify it's stable.
