[Q] Best way to test a battery's health? - Epic 4G Q&A, Help & Troubleshooting

We have 2 batteries, one that's 2 years old and one that's about a month old. STUPID ME, YES, I AGREE, I did not mark either and have managed to mix them up. Both seem to work properly for an hour's test, and I do not want to turn this into an all-day affair. What's the best way to quickly determine which battery is the newer (healthier) one so that I can mark the other as the spare.
Pete

Unfortunately if the two batteries are identical, there is no quick way to tell. Maybe try matching the seriel number to the newest one if you still have the receipt/paper work from the order. Other than that I don't know.

Thank you Kenny.

What's it matter, I'd charge both up and then just keep the other in your pocket, if there's a large discrepincy in capacity then you'll learn pretty fast after both full drain.

Yea I'd say just keep em both handy. Otherwise, the batteries do have date codes on them, but who knows if your newer ones IS new or just "old stock". At any rate I'm quite certain that the "DPQ" line on the battery is the date code, which this is what 3 Stratosphere batteries say in their DPQ line:
DC110922
DC110928
DC120718 [this is an extended life]
Which those all can be deciphered perfectly as a date: 2011-09-22, 2011-09-28 and 2012-07-18.
Hope that helps some...
EDIT: Heck, DC could even stand for Date Code, for that matter lol

Build date year will be the give away. To see which retains the best charge, use each for a 24hr span with regular usage. Then make the least drained your primary.

Let's start looking at battery differently?

Hello friends,
As you may or may not notice depending on your frequency here on xda, we have many people with wide results in the battery department, especially with leaks.
The problem is, these reports are simply not consistant. Posting "I lost 6% in 1" min does nothing for anyone. This post is not to make fun or to bash but to awaken potential ways to help each other.
If you are suffering from poor battery, grab this app.
http://forum.xda-developers.com/showthread.php?t=1179809
Its called better battery stats and the dev is nice enough to allow it for free to xda members. One of its primary features in our case is tracking down wake locks and kernel wake locks. Instead of posting "my battery life is horrible" do some investigating. Try to find out why. Help out yourself, or hell, if Samsung or sprint are here, maybe you'll help them too.
Just a thought, but srzly, "battery life sucks" is no gud.
So as the leaks progress, feel free to share experiences. Help users help you with locks because I can assure some of your poor battery is not experienced by everyone. And if it is, then we can all determine why.
If you need help understanding the app or how to use it, and you can't figure it out from the apps in app help section then ask.
I've got to say, coming from the Evo 3D, this phone has way better battery life for me. I'm not one to pay close attention to battery stats, screen on time, etc. because I'm usually near a charger every where and hardly ever let it go below 40%. I completely understand what you're saying about the user reports though. My favorite is when a rom gets released, 1 hr later you get the "How is battery life?!" Hopefully members will take you're advice and start looking more closely at it and give better info

+1 I would have to agree with that one myself but it also make me wonder what the heck is wrong with people...LOL
Also as stated previously when coming from a HTC device this is like almost having an extended battery but I will make reference in here of battery life in the future... thx
Yeah, I just came from the OG EVO 4G and it's like having an extra battery. I was looking at posts about bad battery life and chuckling to myself.
But I will install that app and track mine, if we/I can improve it then I'm all for it. Be nice if we can get a number of people on board so we have a good pool of stats to work with, might find something.

[q] battery life

I looked to find a similar thread but i didnt see one.
I have been reading in different posts where people have mentioned how their battery life has been with combinations of roms and kernels. I would like to know everyones opinion and their results. From my test and observations, i lose around 10% and hour on my galaxy nexus (gsm version). I seem to get around the same amount of battery life if i use jb or a ics rom. I have seen people claiming they lose 5% an hour and even 1% an hour. Also if you would include any apps you use that seem to help with battery life. Thanks.
This is a small sample of battery life threads.

Most of these threads are closed because no one wants to help. The thread gets closed before it has a chance to get going. Im trying to get a decent thread going where people post what works best for them. That isnt on here that ive seen. I know its a matter of process of elimination but im just curious.
they get abandoned because there are a billion "which rom/kernel get the best battery life' threads.
seriously. try them out.. there is no 'ZOMG THE BEST ROM/KERNEL COMBO EVAR!'
There's a reason why those threads ramble on then get closed. Battery life is extremely subjective.
I have tried them. I know what im doing with kernels and roms as far as testing and flashing. Im just curious what has worked out for other people. I am a flashaholic, i just think it would be interesting to see what other people are using.

[Q] T-Mobile Data Usage Check on Rooted S3?

OK, so I have a rooted S3 running the FrostyJB ROM. When I try using the USSD code to check my data usage (#932#), I get a message that my account is not set up for that feature. Also, both the TMO My Account app and the mytmobile website do not show my data usage, although they do show usage for minutes and text messages.
I ran into a TMO store, and they couldn't figure it out but said it may be due to root. Thoughts? I would like to be able to check my data usage, and every time I flash a ROM, it resets the data usage stats on the phone. Very annoying.

Keep smiling, and the forum is for us all! You Me and any a$$hole that comes along, I guess.
just my 2 cents.

Thought on the issues cobraboy85 brought up about some kernels in the closed thread.

Before i begin let me say I do appreciate all the devs here....but I want to know if what cobraboy85 brought up about ktoonsez and faux kernel really running at higher/ lower mHz than they are letting us know? Reason being is I love his 747 kernels but would never knowingly run my phone at such a high MHz. I personally feel if we are knowingly be miss lead on what the kernel is OCing our phones to it should be fixed. I wouldn't want to fry my phone from being miss lead. No disrespect to ktoonsez or faux just want an honest answer and thoughts. Thx.
Please don't start a flame war, just want some answers.

Whatever the case may be, it is vitally important to be able to trust the source of any kernel you use.
Can you? Probably not. I mean, who has the oversight here? Unless you really know what you're doing.. and let's face it, most users don't - they just install some kernel because another user said "use so-and-so's kernel, it's the best!"
There is waaay more to be concerned about when it comes to kernels than the clock speed (not to take away from those concerns, they are also valid, just not a major security risk).
I never use custom kernels. Just no way for me to tell what's really going on under the hood. Think about it.. call recording, statistical/data stealing such as Carrier IQ.. those sort of things tend to be implemented at the kernel level because
a. they have complete access to the entire system
and
b. it's undetectable to the average consumer, and even some of the most savvy individuals.
Not to say any Dev named here or otherwise is dishonest. I have no idea. But to act like we should just shrug our shoulders and "hope for the best" is idiocy.
If it were me, and I were the Dev, I think I would have moved very quickly to put any misinformation to rest and explain.
But I'm not a Dev
I for one am also interested in this. I am using ktoonsez's KT747 kernel because it integrates faux sound which REALLY improves the sound experience. However, my SGS3 is brand new and I paid quite a bit of hard earned $$$ for it, so I am not really interested in OC'ing it just yet until I'm ready.
I'm no developer but I know in Ktweaker there is an option to enable & disable overclocking steps. I have them disabled. While disabled, CPU Spy shows 6 different "1512" frequencies being unused. When enabled, CPU Spy shows the 6 steps above 1512.
It's probably just the way he coded his kernel to be able to enable/disable CPU steps (because I haven't even seen a kernel before where you could enable/disable overclocking steps before). I think there is way too much being made of this.
They aren't criminals or some masterminds bent on world destruction...I feel like if you had just brought it up as a question in faux or ktoonsez development thread like "hey i noticed this in the code does that really mean it's not clocked at what it says its clocked at?" nicely they would have responded to it with an explanation. They are genuinely helpful and answer everyone's questions no matter how rudimentary or repeated they may be.
And I'd bet money on it being a coding quirk, like a shortcut or workaround or a creative way to give us, who remember do not pay these guys a cent, awesome software for our phones. I think Google or Samsung should pay them serious money to develop kernels for them. They should be rich men with the talents they have.
Ktoonsez, faux, if you read this, I'm behind you guys 100%. Don't let some witchunters and attention whores bring you down. My battery life doubled with Ktoonsez's kernel and I thank him for his hard work. Thank you both so much for your work!
Re: Is the issues cobraboy85 brought up about some kernels in the closed thread true?
No ones on a witch hunt and I'm far from an attention whore....just want to know when I set my CPU controller to a certain frequency that's what it set to. I'm running ktoonsez kernel right now and really appreciate all the dev here in our forums.

Still don't understand why anyone would want to overclock this phone. There is nothing to be gained, except higher benchmarks scores.
Re: Is the issues cobraboy85 brought up about some kernels in the closed thread true?
This thread is complete fail. No one deserves any kind of answer for anything. Both of these devs do this for free. Both do it in their spare time. Both create amazing kernels that I've ran on my phone flawlessly for months.
Even if the clock speeds were inaccurate, who cares? Don't use it. Move on. Whatever. Why so much drama on a development site? These threads are 100 percent disrespectful and if I was smart enough to do what these guys do I would stop sharing my work.

I didn't mean you in I actually meant cobraboy85. (sorry! ) It's indeed a legitimate concern, but the way cobraboy85 went about figuring it out was just plain disrespectful.
When somebody finds something that doesn't make sense or seems wrong, the first step is to privately contact the person, even politely on the development thread, about what they find.
If the develpoer tries to cover something up or hide guilt or dodge questions, they bring it up to an admin or another developer to get a second opinion.
If they determine with other people (with experience) in agreement that something wrong is going on, and administration is unable/unwilling to do something about it, only then do you post something like he did.
Instead he just posts a thread and makes accusations. I think that's cowardly and rude and wrong. Now everyone is wondering what's going on and now the reputations of two developers are being dragged through the dirt for no reason. It's just ridiculous to me.
Re: Is the issues cobraboy85 brought up about some kernels in the closed thread true?
The OP is asking a simple question. He is not accusing the developers of anything. If you don't have the answer, feel free to move along. No need for argument. If you really feel that a thread is out of line, use the report button and let the mods decide.

I have this to say. I absolutely do not stand behind forum trolls who are out to make names for themselves, and cause trouble for those who spend of their free time to make our devices better and free from the grips of the garbage software they are released with.
At the same time, I also will not blindly (note the word blindly) follow what developers do and say. This is the reason why we have things like nightlies for CM; so that code is constantly reviewed to ensure they are not only clean, but optimal.
Having said that, I absolutely TRUST 100% more the word of a developer than a troll. And as for ktoonsez and faux, all I know is that their work has made a real-life difference for me. The sound on the SGS3 out of the box is TRASH. I'm a musician and I'm a pure stickler for sound quality; believe me when I say that their work has made the sound 200% better than it was. And for that, I am grateful.
Although it would be nice for the devs to pitch in this thread and just let us know what's up (they really don't have to), I am apt to believe the cobraboy85 is just a whole lot of hot air. If the kernels were indeed overclocking like he claims, my phone would not get better battery life than with stock; it would get magnitudes worse, because the ROI is just not there for 300Mhz more.
So all in all, either our phones are magical enough to stay with the same battery life AND enhancements with these custom kernels, or someone is just looking to make a name for themselves.

Just to add my 2 cents here...does not all CPU checking apps report 1512Mhz when you set to no overclocking? Kernel source has ALWAYS been freely available as per GPL so no one here on this site is deceiving anyone. Also I have never had a problem with kernel devs answering my questions. If you post a question and in general no less, do you really think the developer is going to see it? As pointed out earlier, a respectful post in the kernel thread would have gotten you the same answer I got from KT last night...no...when set to 1512 your phone runs at 1512.

Sounds like a great question sir. Hopefully someone can tell us how the apps measure speed and if there is a true test app. I do know that Samsung hugely underclocks these phones to give a compromise between battery life and speed. Personal experience is that I get better battery life on the Sprint KT TW kernel than I do on stock. That wouldn't happen if I was at 1.8Ghz instead of 1.5.

I feel the same....by far best battery life with KT's kernel. And it would make sense if it was really running at 1.8 we probably wouldn't be getting such great battery life.

Ok guys, kenny brought this and the SUPER rude thread to my attention so I am responding. Let me start off by saying I NEVER knowingly mislead anyone and sorry a bunch of you feel I jipped and mislead you!
The table the original thread posted about is only about 1 tenth of the code. Here is snippit of code that regulates the table size (again only a little piece)
Code:
int get_the_freq_table(int cnt, int steps[]) {
if (acpu_freq_tbl == NULL)
return 0;
int real_cnt=FREQ_STEPS;
int i= 0;
//if (isenable_oc == 0)
// real_cnt = real_cnt - FREQ_TABLE_SIZE_OFFSET;
for (i = 0; i < real_cnt; i++) {
steps[i] = acpu_freq_tbl[i+1].speed.khz;
}
return real_cnt;
}
Important piece here is FREQ_STEPS = 24 thus not using the other steps which are mearly placeholders for people that are gonna use the OC steps.
As far as the math on the OC, that is my bad for not checking the math. To be totally honest, we were all new to the QCOM chipset back in June/July of last year and kanged from the same XDA dev, not gonna put blame on that person. So in conclusion, yes the 2106mhz after I examined it after seeing that post was indeed lower due to following the original incorrect math. Also it turns out the Sammy original 384 Mhz is not even possible when you try the following simple math:
384,000 / 27,000 = 14.2222222222222222222222
So again, let me reiterate, I NEVER knowly lied to say its going faster or going faster than it is telling you and sorry for the confusion on the OC :good:

Rating ROMs.

Like to start rating ROMs.. Maybe on a point basis..The highest point would be 10 .Have a list of ROMs and there rating next to it.. Just a thought.. Like 9.8 etc... Like in my IMO. MOAR 9.8.
JELLYBOMBED 9.3 etc... Points would be because of customization, stability, functionality, support, battery life, and performance. Just a idea..

Are you sure this thread is a good idea? Since every phone is different and there is no base to start with, ie..must be clean flash only to eliminate corrupted data interfering with stability.

This thread is kind of offensive to the developers. If I was a developer I would be pissed to see a rom I made being rated
Yeah I am not liking this idea one for what Kenny and E said but I have only tried 3 ROMS on THIS phone. Two worked very well for ME but I stick with one over the other well because I am kind of bias to it because I test for that dev. So this isn't the best idea and exactly what E said not good I think this is going to start a "war of words" This is just a differently worded "What is the best ROM" thread.
This is probably not a good idea just use the built in rating system for each thread and give some feedback there
Sent from my Nexus 7
I really see no good coming from this...people arguing, then saying "you trolled this thread and didn't know what you were doing"
In my opinion all ROMs are 10's all around and my hat is off to any that put in the time it takes to get one working and then answer questions and support it for 100's of hours more.
With that said I think we should close this before trouble starts
