[Q] JS7 Info? - Captivate General

I've been looking around trying to find out what's so special with JS7 (apart from the obvious fact that it's new). I'm running Serendipity 5.12 and am planning on moving up to 6.2, which I know is based on JS7. Can anyone give me a rundown of what's different with JS7?

Nothing is really different from the user's standpoint. its another build of the software from samsung, assuming that means improvements and better os management behind the OS.
it will look just the same. but smoother.

This should have been posted in the corresponding sticky in the Q&A subforum.

"1. JS5 is indeed noticeably better.
It's not only faster / smoother, it also fixes a heavy MVNO bug (roaming issues). " - Darkyy
Also I notice that JS7 has much better battery life than on JPY.
I'm at 19 hours, 43% left, over an hour of screen time. By now I'd be recharging.

There are already threads opened with this topic.
On that note, thread closed.

22hrs Std. Battery on GB and Sense 3.0 = YES!

OK, so I know there has been a lot of b*tching about the Tbolt battery life, especially if you are running Gingerbread and a Sense 2.1 or 3.0 ROM (I am running BAMF 3.0 R4.9). I just may have solved this issue when you can connect to a WiFi access point!
Using a program called Tasker, I have created specific profiles that actually help save my battery as well as do a lot of other things to make life easier. The learning curve is somewhat steep for non-Tech geeks, but it's not too difficult after you get the hang of it. (I think the only version of Tasker in the market is pay for use, but you can get a free trial from the Dev's website directly.)
On to how I can get a 22+ hour standard TBolt battery:
1st new profile:
-Called "WiFi"
-Context = WiFi Connected (Any SSID)
-Task = NET>WiFi Sleep>Never
2nd new profile:
-Called "Dim Screen"
-Context = Power Source Any, click "Invert" button (so when the phone is not charging).
-Task = Display>Display Brightness>Set to "20" and check "Immediate Effect" (you can certainly change it to something higher, but you may not get nearly the same battery life).
On WiFi, I can get almost 23 hours of battery. On 4G, I can get upwards of 8 hours, 3G I have yet to test.
Since LTE was just turned on near where I live, I noticed that my TBolt was making WiFi sleep while it sat in my pocket not in use, therefor switching to 4G/LTE and draining the battery. The brightness obviously helps when I am not plugged in no matter if I am 3G/4G/WiFi.
I have some other useful profiles setup. Like I have the phone screen go to Auto Brightness and into the Sense Dock Mode when the phone is charging. My favorite is the Car Dock Profile... when the phone goes into my Car Dock, the Bluetooth turns on, GPS goes on, and Google Music Starts.
I am a big fan of Tasker now... there are a lot of possibilities with the program!

I'm gonna say you might want to try a MUCH more modern ROM. I'm having very little trouble eeking 18 hours out of mine under moderate use, and well over a day if I'm not messing with it much. It will typically consume around 1.7% per hour unused, LTE on.

how do you get the GPS to enable? I've tried to set up my GPS to come when I open maps, navigation or anything that needs gps enable but I get "sorry that action is unavailable on this device."
Llama also does what Tasker does. And its free. I find that Llama works better too. I can get near 24 hours with everything stock.

Modern? The ROM I have is running Gingerbread and is full Sense 3.0 (which appears to be a big battery hog). When I was on a GB Sense 2.1 ROM from the same Dev, I was getting better battery. The only thing that may improve the battery any more on GB/Sense 3.0 would be a new and improved Kernel, though I think I am on one of the more stable ones.

You are right, my bad... it throws up a disclaimer that GPS enabling is not available on any 2.3 ROM because of the Pop-up. They suggest using Cyanogen (sp) if you want to use the feature on a 2.3 ROM.

Potato, Patahto. I like Tasker and found it really granular once I started playing with it. I don't mind paying for an app that is well Developed and supported. (If you like Llama that much, you should use the donate version to "thank" the Dev team!) The 23hrs is an estimated capacity right now as Battery Left is still calibrating.

I think he is refering to roms based off the 2.11 leak. battery life in that Ruu is much better than any other previous ruu. Any roms based off it will give you more life by default. The bamf 4.9 Rom is kinda old when your talking about custom roms and it isn't based on the 2.11 ruu.

You say BAMF 3.0 R4.9 is your ROM. This ROM is old, based upon the 2.01 GB leak (which is about 4 leaks ago), which was terribly flawed in many ways, and isn't even being developed by BAMF anymore. The newer kernels won't even work right on that ROM because aspects of the WiFi and camera have been changed in later leaks.
You're application of Tasker is probably one of the ONLY rational uses of such an app. Using it for such things as turning GPS on and off is pointless, and redundant, because Android already does that as long as you have GPS enabled. Having it enabled doesn't use any power unless you're using apps that abuse it, such as some of the traffic update apps that constantly update your position.
Power management apps aren't quite as useless as task killer apps, but for the purposes I see people use them for, they're not doing you many favors. I'm generally not a fan of these apps and I strongly recommend against task killers because the result of their use simply increases the amount of NAND reads the CPU must make, which is the most power intensive operation that CPU performs.
Newer ROMs, such as the RUU 2.10 and 2.11 based ROMs, are significantly better on battery life than the older ones, especially when used with the radios from the 1.70 OTA, 2.07 RUU, 2.10 RUU, and 2.11 RUU. I'd make the jump to a more modern ROM before I tried manipulating an older one to perform. Or, move up to a newer one and do the same thing and see what you get. In any event, there's good room for improvement.
I tried several ways to conserve battery and finally decided that it just isn't worth it to me to have to stop running game apps, to have to set the phone up a specific way, to carefully monitor what each app does etcetera. I went out Tuesday and bought a extended battery from a Verizon store. With discount I paid $25.00 for the battery and cover. I am now getting right around twenty five hours total battery life off one charge and I have watched videos, played games, played music, and did whatever else I could think of to kill that battery. I am ecstatic with it. Now when I am out overnight mountain climbing with the missus granted I will undoubtedly kill some apps. Wouldn't do to run into BigFoot, Smokey the Bear, and Jason Vorhies with a dead battery and no chocolate bars ( since she for some reason feels I should diet) now would it?
ps. I made sure it had antennaes on the cover. It has more than my original cover does. And the clerk had no clue why i was even asking about the antenaes on the cover

Reps are pretty clueless, in general. They're sales people and that's about it. That's what cracks me up when I see these goofy "corporate memos" that supposedly when out to stores with stuff like RUU and radio version numbers on them. Like the geek behind the counter actually knows any of that???

Yea tell me about it. At the Verizon kiosk in Costco I actually argued with the guy because he was spouting off about the Specs on AT&T phones being better than what were on the Thunderbolt. Saying how much better AT&T was and all this stuff. I listened for only a few minutes before I realized he was an imbecile. He was just throwing out things that made him sound like he knew what he was talking about. And yea you read that right. This brain fart of a human being was promoting AT&T from a Verizon kiosk

Considering I do use a bunch of Apps that can use GPS (Foursquare, Weather, and my Car Dock=Car Home) and I don't always need GPS on to do what I do in them, I choose to have GPS inactive as to not chew up more battery than is necessary.

I have never and will never use a task killer. Tasker is basically a way to create a 'macro' or series of them to help do things without having to click 18 different things on your phone. Apples to oranges.

As I said, if there is a viable full Sense 3.0 ROM with the latest RUU out there, please let me know what it is. Until that happens, I will use Tasker to fix the flaws that exist in my current RUU/ROM.

Really...newer kernels don't work with BAMF 3.0 RC4.9??? That's funny because I'm running Ziggy's latest on BAMF 3.0 RC4.9 with working WiFi and camera, front and back.
Out of all the 3.0, 2.1/3.0 ROM's this is the only one that I have never missed a call because I could not answer the phone because of the end only call bug.
It might be an older ROM but it's still one of the best for this phone.
UberBAMF, Adrynalyne's side-project BAMF, both of the Gingeritis ROMs, Th3ory's ROMs, Synergy... Where the Ziggy kernel came from. Maybe I'm wrong and 4.9 uses the 2.07 base. I've used nothing but 2.07 and newer Chingy ROMs for the last 2 months as daily drivers and I've never once seen this "end call only" bug.
Ziggy's kernels aren't freely available so I don't consider it an available custom kernel.

Anyone that downloads Gingeritis, or Synergy has full access to Ziggy's kernels. I would call that freely available. Either which way they still work on BAMF 3.0 RC4.9.
As for the ROM's you listed not one of them are a full Sense 3.0 ROM like RC4.9.
If you have never had the end only call bug consider yourself lucky because there are theads on both themikmik and team BAMF about this bug.

End-call only bug is real. In 2 months of running bamf (currently on uber 3), I've encountered it once. Others have been plagued with it. Basically, when someone calls, it only displays the large "end call" button.

I hardly call Ziggy's kernel freely available by any stretch of the imagination. That's like saying iOS is free to anyone to use. Not really if you ONLY get it with this product or that! Ziggy also flouts the GPL like it's no big deal, so obtaining his source is nigh impossible. He's got one of the least available kernels that exists.
Sense 3.0 is eye candy. Like live wallpaper, its cool for a day, that's about it. And Rosie launcher is weak. I mean, if that's your thing, cool. It's your phone. But AOSP roms are far beyond BAMF, and far more stable. Shift B2 is the best rom I've run on my Bolt, hands down. With G+ loaded I get between 18-22 hours moderate use. Without G+ I can get a little over 28 hours. This is all 3G, as our towers havent been upgraded yet here in BFE. I understand the desire for battery life on stock battery. I pocket mine for 8 hours a day, so extended battery is unappealing. I underclock to 768 and my phone is still more responsive than it was with sense at 1.4.

[REF] Benchmark Methods (All Phones)

This thread shows the results of some benchmarks of the Android OS (using a Nexus S) where certain parameters affecting performance have been isolated to the greatest extent and then compared statistically.
Background
I teach mathematics, and also used to be a professional sound engineer.
Some of my work on measuring battery drain was published on the XDA portal here however since then further studies were conducted, revealing critical flaws in my original test setup.
Although I believe some of my finding may be generalised to other devices, please bear in mind that my device is a Nexus S, and has its own peculiarities. I have attempted to edit out findings which I believe may be specific to the Nexus S, but I have linked to the original thread in case you wish to go exploring further results, or get an overview of my methodologies, which are usually in the second post.
Please feel free to post or PM with any queries, and I am more than happy to help if you want to apply my techniques to your own device.
Results
Over my time here in XDA I've built up a few studies on the Nexus S.
Here are the links. There are summaries in each thread in the first and second (and sometimes third) posts of the main findings, but I've done some very quick and minimal overviews here also.
ICS ROM Benchmarks: this thread
-Freely available benchmark programs were used to determine which ROMs had the best performance. Among the top six were an AOSP ROM with some CM9 parts, MIUI, and Stock, all within about 1% of each other. My conclusion was that the gingerbread tweaks we all knew and loved didn't improve performance with ICS, and in some cases, enthusiastic young developers were throwing together incompatible tweaks that hurt performance.
Battery Drain Benchmarks: this thread
#1 - With screen on, the slowest processor step saves the most power (duh... )
#2 - Regardless of your choice of governor, even with extreme undervolting, you are not going to be able to increase your battery life by more than 2%. (Click here for explanation.)
For the instability introduced by UV, it seems a 2% increase in battery life isn't really worth it! REMEMBER rebooting uses so much power, a single one would more than undo any savings made by UV.
Also, undervolting seems to cause more reboots when the battery is running low. This makes sense, as the battery runs low it loses some of its voltage (which shouldn't be confused with remaining power capacity).
#4 - This is one point that everyone ought to know, but I'm including because many people seem to believe in myths: if the screen is off, and the CPU is not active, neither deep idle nor UV will have any impact on battery life.
#6 - If you have an amoled display, black saves a great deal of power. After that, red. If you have a black and red theme, this is saving you power!
#9 - For amoled displays, Kernels higher FPS mods will cause the screen to drain about more power. For instance, on the Nexus S, 65 fps drained 10% more power than 56 fps. Also, 50 fps saved about 7% power compared to 56 fps.
#11 - If you've got no reception, you might as well be in airplane mode, because searching for reception also eats battery.
#12 - If your phone can't handle OC (or UV for that matter) it's because components in general are built to cost, which means factoring in tolerances, and every chip is made as cheaply as possible within the specified tolerances. Outside of those tolerances, whether your chip can cope or not is unfortunately down to the whether you got lucky with the individual device that dropped off the manufacturing line.
ARM document on A8 fault tolerance: http://infocenter.arm.com/help/index.../Babhjhag.html
In fact I measured how UV in particular can cause errors, and saw in action the A8 using MORE power to correct the errors.
CPU Governors and I/O Schedulers: this thread
-Interestingly, CFQ generally performs very well, and deadline. Most custom kernel developers in the Nexus S section recommend a version of deadline that has been tweaked for flash storage. In one of my unpublished benchmarks deadline performed slightly better than CFQ.
Does SuperCharging work?: this thread
-This was just a short study to find out if this script is suitable for the Nexus S, but it turned out it had no effect, positive or negative. This script was probably more use on devices that had less memory. One benefit that remains is to 'bulletproof' the launcher.
Kernel Memory Allocators: this thread
-This is another short study for kernel developers to show that SLUB performs best.

Ways to increase battery life?

My wife uses a rooted Bolt running Virus' Eternity ROM with Sense 3.5. I'm open to trying new ROMs and other less drastic measures as well. I've thought about switching to an AOSP ROM that might free up more memory. I personally use Liquid Smooth and have been trying tweaks to see if my battery life improves before trying to change hers. She uses the FM Radio a lot at work which is the primary culprit of her battery consumption. It's generally fully dead after 6 hours. What options do I have that might increase that life a little longer?
You may wanna take a look at THIS THREAD
Thank you much. I'm not sure how I've missed that thread as I've spent a good bit of time on those forums as well looking at different tweaks.

amazing battery.. better possible?

I'm using current venomxl Rom with elemental kernel (all default other than max 1.5ghz and flu overclock off) and getting what I feel are amazing results on battery life. On phones of the past, aosp style roms pulled better battery life, but I saw here in the forums people were getting better battery life with sense roms? Is that true? I posted a screenshot below of my battery life, sorry couldn't figure out how to get jpg link from dropbox app.

Would be nice to hear what Rom/kernel combos others are using and what kind of battery life you are getting.
Put the picture in your public folder. Right click on the picture and click copy public link, or something to that effect then paste the link in your thread.
In any case, the only things you could do to get even better battery would be to undervolt your processor and maybe underclock as well. Some phones become unstable however and while I noticed the general ui and most apps run fine with a clock speed of about 1.2ghz, some, more CPU intensive apps do lag a bit. You can also disable radios when not in use. I actually use juice defender to do this for me automatically, which is pretty handy though not everyone likes the idea of having an app do that for you.
Last but not least, if your radio signal seems low most of the time, you can try flashing different radios to give you a better signal which will, in turn, increase your battery life.
Hope this helps, maybe others have had different experiences?
I use viper and bulletproof right now ad I wanted a stock kernel with swipetowake
And this holds up damn well in terms of battery life. Never used elemental for long though so not sure if it's better or worse.
*edit* I forgot to add, you can also turn off fastboot. Your phone will take longer to power on but saves some battery life.

Such reports are often just anecdotal and very subjective. Like you, I've also seen people claim better life on AOSP or certain ROMs on various devices, but never really experienced it in any consistent or meaningful way. Battery life often has more to do with the radio and reception in your specific care, than anything. Sure, various ROMs on various devices may have some subtle difference in battery life. But unless you are very methodical and scientific about comparing them, there are just too many variables involved, and you are often just left with subjective reports and placebo effects.
Can't open your pic. But if you are satisfied with the battery life (enough to call it "amazing"), I'd just go with the ROM that has the features you like the best, and leave well enough alone.

ROM with best battery life

Hi
A friend of mine is endlessly complaining about the bad battery life on his stock nexus 5, the phone is off the charger at 7am and is all but dead at 4pm
Being a nice guy and all, I want to help him out by offering to install a ROM that optimises battery life.
Can anyone suggest a good rom for the task ?
If such a rom exists and battery life can be extended to 15 to 17hrs I might jump ship from my LG G3
None
roms have absolutely nothing to do with battery.
battery is determined by your personal use, your personal setup, apps installed, and very much the quality of your phone/data connection. there are other things that'll influence battery life slightly as well, but these are the main things that determine your battery life.

Autobrightness isn't too bad if your ROM allows you to change the values/levels
Also, "Lux Autobrightness" is useless for saving battery on an LCD screen since the backlight is still the same brightness. on AMOLED (aka not the Nexus 5) it would help, however.

battery is determined by your personal use, your personal setup, apps installed, and very much the quality of your phone/data connection. there are other things that'll influence battery life slightly as well, but these are the main things that determine your battery life.

so we shouldn't expect any battery improvements when Android L is released ?

its possible, a small amount. but that would be from new code that makes something more efficient. but, i personally, dont expect much difference in battery life.

not sure I agree with you, project volta looks like a concerted effort from Google to do exactly that.
Funny. I always use Auto-brightness and get 4 hours SoT at least twice a week. Other times, I get a little over 3 hours or below.
The best battery life for me is with elementalx 1.05 kernel with a stock rom. 2 days stand by and at least 5 hours sot is the usual verdict.
But i think the problem here is how your friend uses his phone
Different ROMs do have different battery usage. Even with the same kernel. He could stick on stock with elementalx aosp kernel. Then mess around with trickster mod to suck out the most use. Only use the high power goveners when needed. Then switch back to low power for general use. Honestly, had my n5 for a month. Also had a n4 before. The n5 battery isnt much better. Biggest downside. Just doing nothing its fine, but if I play some games on the train it dies in no time.
Some ideas
Vanir
Slim
Purity
Cm11
Vanir with elementalx was good for me battery wise. But after a certain nightly I was getting alot of heat and battery drain. Im now using sabermod carbon with elementalx.
Turn Location off. It has the biggest Impact in Battery life time.
"Best" ROM.
There is no such thing as a best ROM. The question itself is ambiguous. "Best" is obviously a subjective term.
What I want from a ROM may well differ from what you want from a ROM, ergo - what is best for me could be worst for you.
If you are asking what the most popular ROMs are, or which ROMs people are using, you can see which threads stay around on the first few pages (and have the most posts) in the Android Development or Original Android Development forums. You can also see what other people are running by reading the What are you running on your Nexus 5 thread.
If you are asking which is the most stable, being a Nexus device - they're all pretty stable.
If you are asking which is best on Battery, ROMs only affect battery if they have a feature that is badly coded. You will likely be able to read about this in the ROM threads. ROMs do not impact battery life. The only impact to battery life are your apps, your settings, how you use the phone and mostly, environmental issues such as Phone Signal.

"Best" Kernel
Also, please note that as above, "best" is still subjective. What we all want from a kernel is different. Again, many people have the misconception that Kernels affect battery life. Let's get this cleared up. Although Kernel devs will build in optimisations and efficiencies that will improve battery life, these are very, VERY tiny...and if 1 kernel has these optimisations, they likely all have.
People will often say "Kernel x is better than kernel y for battery life". This is actually wrong. Kernels respond to user settings. Setting up the governor to favour either battery life or performance is simple enough to do, you just have to do some learning. The reason people think Kernel x is better than y is because developers set their kernels up with their preferred governor settings. This is what we refer to as out-of-the-box settings. The out-of-the-box settings for kernel x may well produce better battery results than the out-of-the-box settings for kernel y, which favour performance. The fact is, you as the user have the ability to tune kernel x or y to perform the same, be that battery or performance - so start learning how to do this yourselves - that way, you can choose the kernel based on the FEATURES you want, and not the fictional performance benefits of one kernel over another.
Hope this helps

with this guy
I used about every rom and kernel.... And my battery life for me, with my lean setup and usage was always 24 hoursish total and usually over 6 hours screen time on all of them.
So no one will ever convince me that different kernels and especially different roms affect battery life any more than in the smallest ways. Definitely not enough difference to base a choice on solely.

Well said. I hope you don't mind but I've linked your well written response in a Reddit post. Users there argue daily over which ROM or kernel is best for battery life despite my best efforts.

Not at all. I'm just copying and pasting it wherever needed now.
