[Q] Smartphone newb in need of gen advice - General Questions and Answers

A few months ago I bought a HTC EVO. It is my first smart phone. I am not what I would describe as a heavy user.... My web/phone mix is about 40/60.
I was referred to this site from guys in my car club. They recommend some sort of rooting? and kernel? for battery life....
My batt life sucks and is unreliable when I'm on the move. Even a short drive with virtually no use will kill my battery. I haven't tried the recalibration. I just actually read about that process but frankly I don't understand the directions 100%.
What do I NEED to do to this thing in order to keep it performing top tier and extend my battery life?
Should I remove my advanced task killer? What about antivirus?
I am super computer ignorant. Cars are my thing, computers not so much. What the hell is a root? What is a kernel? What is removing sense? ROM meaning Read Only Memory? Is this something I need to physically add to my device? Will I run into support issues after all this stuff?
I need some solid, straight forward advice in lamen words about what I need to properly maintain the software on this thing.
Thanks a bunch!!!

I realize this may not be the best section for my question.....
Mods/Admin can you move this thread to the Android section that would be the most appropriate?

Ok, well i dont have an evo i have a mt3g but i will tell you a few things. There are a lot of people that say task killers do more harm than good. Android already has a way of killing tasks on its own. Antivirus never caused an issue for me. If you have no interest on computers or knowing your phone that personally i would not suggest you root. Rooting gives you super user permissions. Basically an all access pass. Of course they have issues as nothing is perfect. You can see that from running into issues stock. A kernel if i understand correctly is what controls the communication between the software and the hardware. Some have better battery life than others. You have to be rooted to flash them though. Setcpu can also control your processor speed for better battery control. Again you need root to use it. Sense is what your phone runs on stock and some people like it others dont. Rom- Yes read only memory. There are different ones you can flash to totally change your phone. They run different on everything as well as battery life, options, look, feel ect. Again you need root to flash custom Roms.
Hope this helps. Also you can go to the evo section here and read all the info you want on rooting, roms, flashing, battery issues, ect.
This should have been in evo Q&A section. Not complaining or anything strictly fyi so you know next time and where to look for your info.

Humble vs gummy froyo

Title says most. I am going to be getting my charge on tuesday and have been doing some research about what rom to try, and gave it narrowed down to these two. which one do you like more and why? I have read the threads on both and they seem pretty even, just wondering which one you prefer and why...thanks for any and all responses!

Perhaps you did not research enough, enjoy.
http://forum.xda-developers.com/showthread.php?t=1171270&highlight=humble
they are both good but I prefer Humble because of the battery savings...Gummy is very snazzy looking though and works pretty much flawlessly and quick. Its a tough choice honestly but I personally want/need the battery to be as efficient as possible and for the Rom to do everything I need it to do.....Humble does that for me..as an example I have been unplugged for 9 hours---dropped 31% battery! I say thats a pretty nice win!
Of course your mileage may vary and everyones battery life is different...I think either way you will be happy...I say try both for a few days each and see
I will be trying both personally...but I have to flash one on both my daughters and wifes phones as well..and they hate it when I change their rom after they her their phone setup

Heard that, thats why I never work on my familys phone anymore. Lol.
Why do you have to flash it on both of their phones? Just try it yourself and then give out the goods lol,

No one seems to get that battery life is 99 percentinfluenced by the kernel....most framework mods that claim battery savings are either placebo or stupidity
Humble gets good battery life because it packagesimnuts undervolt kernel in
Use the same kernel with gc and you will get virtually identical results

There is little to nothing in a rom that would impact battery life unless there is an app that is not letting the phone sleep if something

well at any rate it is a truth..I have tried gummy on 2 totally separate occasions and battery life on Humble(which I have also tried switched back and forth from) is a decent amount better..I dont know why but it is......I always flash the same exact kernel which is Imnuts non OC one
I was using imnuts pbj voodoo kernel and decided to try gummycharged and it just locked up the phone, sloooooow reaction to moving screens, scrolling, opening apps, etc and would lock up all the time... might've been my imagination but data (3G/4G) seemed flaky too, even after several wipes and reflashes. Guess my Charge doesn't like it Oh well I just loaded up the debloated EE4 and it flies with imnuts kernel

uhmmmm i want better battery life. i'm a CS major too so i'm fine with technology, i just never wanted to pay the 30 a month for data until now. and i've had the phone for a few weeks now.
Humble has great battery life, don't want to disregard what Nitsuj said but I swear I have much better battery life switching over to Humble then I did on GC. It might just be the battery gremlins but the battery life was noticeably different, maybe it's just my imagination since its advertised to be a low power ROM.
Humble has some cool animations, it's sort of a love hate thing. You may get incredibly sick of it after awhile but you can easily turn the option off.
Humble is updated very frequently, that might not be a good thing for you. It's very easy to flash the updated versions if you're already on Humble but you may not want to keep downloading new updates every few days, I personally love it. Keeps the ROM fresh.
Humble doesn't have that nasty freeze/reboot issue that happened about once every day or two on GC. Might have been a bad flash but I read about others saying it happened to them as well.
I believe Humble has an increased Dalvik cache which supposedly is the source of increased battery life. I have personally never used GC, but flashed Humble on day one and fell in love with it compared to the stock ROM.

I hate it when people that obviously have no clue as to what they are talking about start making BS up.. Especially ones who disagree with people who obviously know a ton more than them like nitsuj17....
I can tell you right here and now that there is no way that Humble has significantly better battery life the GC or vice versa..
I am not here to rip on Humble its fine rom (Its built on the GummyCharges base) and if people like it better than GC than that is fine. But people who spread BS piss me off.
I have been making ROM's for the better part of a year now across multiple Phone(three) and will tell you that any ROM especially ones built from the OTA (such as these) will never see an increase of more or less than 5 ~ 10% better battery life with any tweak you can apply. The increase they do get is from removing bloat and install custom Kernels..
If both ROM's were set side by side with the same kernel they would more or lass last the same amount time under the same utilization.
Making a change to the heap size in the build.prop will not change battery life, anyone who tells you that is full of $hit or obviously clueless..
Sorry gotta call FUD when I see FUD
To the OP I suggest yo try out all the ROM's and make the decision based on your own opinion.. Most ROM's will be a vast improvement over stock.

how is my personal experience making BS up? Like I stated I dont know why the battery life is better. I am not a dev or even super experienced in smart phones. but the fact is with the same Kernel and the exact same apps running that are restored from TB on all ROMs the battery life is different. I appreciate everything that everyone does here to improve and make these devices better than they originally came out. The things you guys do and the knowledge you have is crazy. Way more than I can ever understand personally.
Maybe it was an error on my part when I installed the other various ROM's. I dunno...but my own personal experience is not BS. Its upsetting to have someone claim that my honest experiences with my device are BS. I receive no benefit to claiming either is better or whatever. If you see post #3 I pretty much said what you said. try them out and form your own opinion.

Because like it or not your opinion is based on perception and perception is easily fooled when it comes to battery life on these phones. I have seen it again and again. People believe that one ROM has better battery life than another bla bla bla.. Most if not all those people have no numbers to back up their assumption.. To top that off I am sure you did not recondition your battery stats before using each ROM.
And on top of all that its almost impossible to create an environment where you actually test each phone equally.
So what we have to go by is what is actually changed.. And I can tell you here and now... Its almost nothing, nothing under the hood is that much different at least in the modules and drivers and radio and kernel. And as someone who is a dev I can tell you that nothing about either ROM can make that much difference in battery life.
I have gotten good results and battery life from humble. First time i used gc it didnt do well on my phone. Not sure why. Second time around it was much better.
I also used altered beast v4 and it was just awful on my phone. Exchanged my phone for a new one and installed the same v4 as before and it was like a totally different rom.
I have had similar experiences with blackberries as well and if i remember correctly people always said roms act differently with other same model phones
I always set my phone up the same way and with the same apps and widgets.

Known Android Myths

Hello I usually don't post stuff like this, but whenever I see someone answer something, they are not telling the fact, but the myth. These myths are well known "solutions", but never work, since they're myths So I'm here to tell most of the myths that people are spreading... If you have any other myths that you'll like to talk about or if one of my myth is false, feel free to post about it . So without farther ado, lets get started
Task Killers: As much as this is obvious, people still uses it. So much, that it is annoying. Android handles apps and tasks well. However, there is an exception, and that is when the app constantly freezes or crashes and you need to restart it. If that's the case, there's a "Running Apps" section, where you can force close apps under system settings. So you won't need 3rd party Task Killers, EVER
Battery Calibration (Draining then fully charging): People thinks that this is good for your battery life, but it isn't. The only thing that this does is make the system read the battery percentage more accurate. Doing this once per month might help you improve read battery % better, but it isn't necessarily at all.
Wiping battery stat when the phone doesn't charge up to 100%: This myth is quite annoying. I dunno about other forums, but in Galaxy Nexus forum, quite a few people use this myth as a answer. Wiping battery stats DOES NOTHING to how system reads battery%.
Anti-Virus app: This is another myth that is obvious, but used by many people. You don't need anti-virus apps, unless you download a lot from untrusted source (4shared, because it is uploaded by people, not the company). If you know (And you SHOULD) what you're downloading, anti-virus is nothing.
Benchmark: People get so hyped about benchmark results... And I dunno why... It's just a number, I tell them. It wouldn't matter in daily usage, I tell them. But they do it anyways... Benchmarks are just numbers people. My Gnex can be as smooth and fast as GS3, but have a significant difference in benchmark tests.
Quad-core is faster than dual-core: While this isn't a myth, it isn't 100% correct either. You see, in daily usage, the phone only uses and needs a little bit of CPU power. For example, Facebook app doesn't use full 4 cores. That's just plain silly. However, when it comes to heavy gaming, yes, that 2-extra cores will help. But overall in daily usage, you're not gonna miss almost anything, because you have dual-core...
You need to clear cache and dalvik when updating/flashing a custom kernel: This is not true. I flash Franco kernel without clearing anything with NO problem.
You need to fix permission whenever you dirty flash: I don't hear that too often, but people still believes in it. Fixing permission isn't necessarily, unless you're experiencing random force close or crash.
Turn GPS off when not using: You do not need to do that at all. Phone only turns on the GPS when it needs to. For example, when you open map app, you'll see the GPS icon on the status bar, but when you exit out, you won't see it anymore. This means that the GPS radio is off. OFF. No need to waste your time turning it off and on.
Switch to 2G (Edge) when screen off to save battery: This is probably one of the biggest mistake people do to save battery. Yes, 2G does consume less battery than 3G, but constantly switching between them just burns the battery. It is just pointless if you ask me. Either stick with 3G, or stick with 2G. Constantly switching between them will be the worst choice.
Undervolt as much as you can to save battery: This is not true. Undervolting to a certain point can help you extend your battery life, but doing it too much will drain more battery instead of extending it. Also it makes the phone less stable, so make sure you know what you're doing and don't undervolt like crazy
iOS apps are more optimized than Android, and is more stable: This is part true but mainly not. Yes, dev only needs to worry about 2-3 screen size when making apps, which means that apps can be optimized for the screen size, but that doesn't mean much anyways... Also did you know that iOS apps crash more than Android? Now you know
iOS is better than Android : Lol wut?
Hope that cleared few things up. Again, if you got a myth of your own, feel free to post it in the thread!

Some interesting stuff
Sent from my SGH-T989 with Cyanogenmod 10 Alpha Power.
Quad core uses more battery than dual-core: this confusion comes from the intuition that "you'd need more power to run 4 of them". In fact, the results are closer to the opposite: on those rare occasions where multiple cores are used, they allow for faster processing (hence more sleep) and less intensive. Mostly, however, it just doesn't make a difference.

"Turn GPS off when not using"
I turn mine off when not using it for navigation because i dont want apps......yes that ive given permission to......to access my location.
Nothing to do with battery.
But good list!

We should send these in to mytbusters so they can prove/disprove the facts. I personally use appkillers because the newer ones to make a difference on my underpowered P500. While these apps to start up, they consume less memory when started in the background and allows for faster start up once killed by the task manager.Android does have impressive memory management, but nothing is infallable.
Battery stats is just silly, if you keep charging till 90% then unplug, you can make it appear that your device can run for days on one charge, so that is very misleading.
Benchmarks are worth noting when it comes to gaming performance. On my device ICS definatly scores lower than gb, yet it runs smoother day to day. Playing games is tragic simply because the drivers are an issue on this device for ICS.
You dont need to clear the dalvik cache or normal cache to flash a kernel, the kernel modules are loaded at boot. The linux core behind android was designed this way. Clearing them when you flash to a different rom eg: AOKP to CM9 its a good idea to flash the cache since this could retain incompatible files between roms.
Myths arent annoying, people clinging to them for no reason is annoying.

I also had P500 and app killers did almost nothing at all... Maybe it's just me?
That's not what I've meant when I said about battery stat.. Some people's phone just doesn't simply charge all the way up to 100%. And others just tell them to clear battery stat, which does nothing...
Benchmarks ARE pointless in my opinion. I personally don't think that noting Benchmark scores are needed... Also they are not very accurate either. What I mean by that? Well, in real life (including gaming), even if you overclock, the performance isn't so huge. But in Benchmark scores, little overclock increases the score a lot.
I know myth itself isn't annoying, but people spread them. Like crazy. And that's what irks me

How to select a kernel?

Hey guys,
So, I was wondering.. I am new to the all android experience, I am learning and I am enjoying tweaking and messing around with my phone.
Problem is that I am really un knowledgeable when it comes to kernels and roms..
I tested at least 5 kernels today and tbh apart from system performance on antutu i'm not seeing much, i'm wondering how people can reach 19 hours on here when no matter which rom or kernel I pick my phone just keeps draining pretty fast when i'm playing games..
I want to learn, to understand more.. but for that, I need help.
I want to know how to select a good rom, a good kernel, what features to look at, how to mess with voltages and etc..
I would love to learn, so someday I can be the one assisting other android users.

Only one way to do that : READ READ READ READ and read some more. And don`t be afraid to try things like flashing roms, kernels, recovery`s, mods. Always read the OP`s of the devs well so you`ll know what to do,

Thing is that most people here are already.. " in the zone " when it comes to knowledge, so they speak the language that I don't understand.. it's like chinese when I first look at it.
How does a beginner evolve like that?
Btw: I was wondering maybe I should test kernels and roms for a period of time instead of periods of hours? because I don't see immediate results I just switch a rom or a kernel not really giving it a chance to evolve

This is a very good start to stop beeing a` NOOB` and eliminate the risk of bricking your phone.
All users start from scratch bro, we all live and learn till the day we die
First don't care about bemchmarks. They mean nothing in term of user experience.
Second a kernel must be tried at least during one or two days.
Third there is no best Rom our best kernel. Golden rule. Each person has different needs and tastes.
And be careful when you see amazing battery times. What matters is phone usage. Good phone network ? Wi-Fi? Localisation always on? And so on.
What surprises you when you play your battery drains? Normal.
What makes difference is 'idle' time. Use Greenify, fight backend running apps.
Some people spend days tweaking their phones, and though don't have time to use it...

this is normal... what do you expect when you stress the CPU/GPU?
Thing is, you don't just change kernels and run. Many of the efficiencies you gain with custom kernels comes from the tweaks you make to the system made possible by the kernel. These are where you can get increased performance in many respects. Keep in mind, though, no matter what you do, the processors will still be hungry under load and there is not much to do about screen use except brightness control. (i.e. games will kill your battery faster than just about anything else)

Have you checked into finding out which apps and services may be causing your phone to wake up often, or even not sleep at all? Learn about wakelocks if you haven't already. There are good tools for finding out which ones are affecting your battery life, such as BetterBatteryStats.

[Q] Rooting and its basics

I've rooted one phone in my history of rooting - the mytouch 4g. I found it very unstable during that process thus my hold off of rooting until now.
I have a Nexus 5, thus me creating a thread in this forum. I know many will just tell me to google or whatever but I rather get someone's actual response to my post.
That said, what is the different between a ROM and a Kernal. And how can one tell if one is better than another?
I think I want what everyone wants in their phones - stability and extended battery life.
Thanks again.
a rom is the ui, it gives the user variables to adjust and can add some features. a kernel is the central control of your whole phone. it ties the cpu to the rest of your phone, and to your ui. the kernel is like the brain, where the rom is like the outside/skin of the body.
hiw do you know which is better? only by trying them out. some phones will like certain kernels better than others, and you wont know which until you try.
Hi,
Sorry to give you a link to explain what is a rom and what is a kernel, but anyway: http://forum.xda-developers.com/wiki/index.php?title=ROM-VS-Kernel, for me it's a good start.
About battery life it's not the rom that will give you better or worse battery life (unless a "bug"), at least the kernel can play its role but it's mainly your use and settings, the apps you use...
If you have a bad signal reception or a rogue apps with a ton of wakelocks, whatever the rom or the kernel, it will be always the same thing.

I`am not rooted also atm, the device does everything that i need it to do to be honest. Rooting is handy and usefull if you want to use features or do things that cannot be done with the stock configuration. Read the first 4 threads in the General section well if you want to learn the basics of rooting.

Battery issues

Hey guys, was wondering if there was an app I could use to control the CPU speed and cores of my galaxy s5. Any app I use seems to reset itself upon exit, and I have not been able to get clock speeds to stick once, despite forcing it to set on boot. Any help would be appreciated, I keep losing close to 1% every minute of usage. Thanks.

There are a lot of factors involved in the Battery of your device. Keep in mind that not all devices act the same. Also the way you use your device. What apps you have. Cell reception. How often you check your Email. How often your apps sync. These are just some of the factors involved in how long your battery will last on any given charge. With that in mind, yes, you can increase the Battery life on your device. Are you Rooted ? What Rom ? What Kernel ? Which Android version are you on currently ? What Recovery are you using ? I know these sound like a lot of questions. But it's much easier to help you with more information.
Lastly this really should be posted in the Q/A section. It will get faster responses there.

I'm on aosp lollipop, I use greenify for my apps, keep app count to minimum. I know what can be done to manage battery, but all I really need is an app, or method to manually control the CPU of this phone. Like I said, any way I try doesn't allow CPU speeds I choose to stick.
I'm not familiar with AOSP, but are you using a kernel that supports changing the cpu speeds?
