Q_ modem and kernel combo

Any help would be much appreciated. I'm currently running cognition rom v3.04 with a firebird v2 1.0 (firebird splash screen not death star) and a kpn1 modem. My problem is that I need raw performance. Battery life doesn't matter too much as I carry a newtrent battery pack and have access to a a/c outlet most of the day. I have mostly geographic problems. Living in a rural area with few towers and the fact that a active volcano keeps spewing volcanic ash and sulfur into the air seems to be killing much signal. I know that there are lots of recommendations on specific areas as far as combos go but I can't find any for hawaii. Thank u in advance for any help given and also a big thank you to all you great devs out there! Please keep up the good work so us on the ground level can keep reaping the benefits. Especially here in hawaii where support is non existent!

Im not sure any modem you flash will help with volcanic ash, lol. I like kp1 as my modem, but jk4 and jl2 seem to be popular choices also. Your best bet would be downloading one of the signal strength widgets from the market, then compare a few of the modems. Trial and error is usually the best way to choose your modem. Good luck!

Thanks. Finding a way around actual dirt in the air and lack of repeaters and towers is proving to be the main hurdle. I will get a signal app and start the trial process. The price of living in paradise seems to be coverage.

Are the Samsung Captivate and the Vibrant the same?

Well, that. Are they the same "under the hood"?

Not entirely. While both are Galaxy S phones, there are some significant differences that makes ROMs non-interchangeable.

For example?...Except for the networks frequency both phones use, they seem like twins with different clothes to me.

you can swap roms around between them, but you have to make sure you use a kernel AND modem made for your device in the rom zip. also, it seems that some of the framework in vibrant roms causes higher battery usage on the captivates...

^^^^What he said. The differences are small, but enough to cause issues ranging from important to minor. Most can be overcome with the right kernel/modem setup, but you'd probably be better off with a ROM specifically designed for your phone. And some carrier differences are problematic. Heck, even within the Captivates, there are some significant differences between a Rogers i896 and an AT&T i897. Then there's the issue of European Captivates that are slightly different from their U.S. counterparts. We can't even get the same ROM to run the same on all Captivates.

So they are the same. Just with little difference, but at the end of the day, they are twins. Just as i tought. Thanks for your answers!

Not twins, unless you mean fraternal and not identical.

just be careful. kernels and modems are not really something you want to mess with if you are unsure. always replace the kernel and modem in a rom zip with a pair that work with your phone....

I would say they are different enough that you should stick to the one you have as far as getting ROM's and other such info. It is too easy to miss some minor difference.

close specs really but the gps chip is different, the vibrant technically can get fm radio output from the gps chip but i dont know if the circuitry is there to enable it. the captivate does not have any chip that can support fm radio. also the vibrant is so close to the i9000 that the ffc fits and can be enabled with an i9000 kernel, the captivate has no room for an ffc and we are unsure if the board can support it.
so of you are talking off the shelf features that are not rom related then yes they are basically the same. but they do not have identical internals or features, the tmobile roms have some things that att likes to take out or charge for.

LTE battery use

All my phone's in the past I have gained a fair bit if battery life by turning off LTE and sticking to 3G. I have read that the chipsets used in newer phones including the One are now much better and you can actually save battery by having it on as the modem spends less time sending and receiving data. How true is this?

Six Days of Battery Life?

Hi folks,
I just ordered a Nexus 6.
I currently have a m7vzw (Verizon HTC One M7), and cut my teeth here rigging s-off and root, and then trying many different ROMS for it. My needs are pretty simple and, as you can see from the title, I like long battery life.
I currently run Vanilla AOSP 4.4.4 and minimal edition gapps. Light email push from gmail and to MS Outlook for work. Very little surfing and phone use. No extraneous apps, and no social networking apps. I typically need to charge up every 6-7 days.
Any suggestions for some ROMS to consider here? I never exceeded 3 days on my current phone using 5.x with the same usage and configuration. I quit trying after a while.
Thanks for your time

Errrr... I guess if you leave WiFi and data off you might get a couple days if you don't use screen often? Most get 3-6hrs screen on time to give a day to a day and a half?
Probably not getting 6 days, if you are, your spending way to much for your phone, because you obviously are not using it [emoji14]

Lol seriously though. You're the type of phone user to get a months use out of a ZeroLemon battery.

I have near-constant access to much more powerful equipment for business and gaming. I have some very specific needs that my phone addresses.
Is there a better place I could post the question? Does anyone here have the expertise to provide useful answers? Or does the sarcasm indicate that this device has stupidly low battery life, regardless of which ROM is used?

I fun stock 5.1.1 unencrypted, with Lean Kernel and a flashed.zip of the drives from the M preview.
I went from 7PM Sunday night to 3:44PM Wednesday Afternoon before charging my phone. I also have very light usage like you. That included 30+hrs of music listening, 2hrs SOT, a few camera shots and all my Google, work email, and Skype accts on ans syncing,

Seems to me that android M will work out for you.........I run M preview 3 currently and made it last weekend from unplugging Friday around 12 noon and plugged in Monday (labor day) forgot my charger at work over the weekend, but plugged in Monday around 11:30am and still had to about 25% remaining, had to use an old charger (not turbo charger) but I was afraid it would die overnight while I was sleeping and the alarm would not go off for work Tuesday. I don't remember what all my stats were, but very light usage since like I said, my turbo charger was at work
Good luck, nexus 6 is a great phone and tweaked right should yield very good standby time
Thanks

which rom or kernel you use will not have any influence on your battery life. battery life is determined by your personal use, your personal set up, which apps you decide to install, and very much your phone/data signal quality. everything else has very littke affect on battery. that said, i personally see about 5.5-7h screen on time. and that pretty decent. but 6 days battery, while using your device, youll never see. only if you dont use your device for long periods of time and if you have your signal turned off.

the device doesnt have stupid low battery, your previous experience, and expectations are stupid high.
tbh, short of turning off data when the screen is off, and having extremely light use (like almost none), i couldnt even speculate what phones could go that distance consistently, short of leaving the phone sit there like a paper weight and never using it.
not trying to be smart, just being realistic, given my experience with about a dozen flagship smart phones over the years.
the guy who commented about the zero lemon battery might have been being funny, but seriously, for the longevity you expect, you should be looking at phones that have zl support.
i have a g3 with a zl battery. with average use you can get 5 days or more, and easily increasing with lighter use.
i tested the n6 before for life with less than 1% use vs time, and it was in the range of 6 days. but that was running a premium rom and kernel and strong service always.
where the n6 excels imo is for the normal user. i have shown proof of 8 to 11 hours screen time during a normal days use consistently.
most people are happy to make it through the day, and charge nightly while you sleep. when you state an expectation of 5-6 days, the comments are undoubtedly not going to be up to your expectations.

I respectfully disagree. I tried several ROMs on my current HTC One. On average, the late 4.x series lasted twice as long as the 5.x series with the same apps, usage and locations. I realize you can attribute whatever battery life fail was added to the OS as "personal set up" or "app". But it is what it is.

My expectations? I've been charging my phone once a week for several months. I went through several configurations to get it that way.
Obviously my use case for the phone is different from yours. I typically use under 300 minutes talk, under 300 texts, and under 500 MB data monthly. But I depend on email push throughout the day, need text and voice when there's an issue, and need reliable data and a good screen for remoting to my servers if there's a problem.
I don't give people grief about how they use their phones. Evidently it's a fun and popular thing to do here. Good luck with that.
Thanks for the statistical info. The bulk of the battery case is duly noted as a last resort.

honestly, i have no ideas about an htc, considering that my last htc was the g1, which i got in oct of 2008, lol. but whatever rom that you use on a nexus, does not have anything in it for battery life, besides whats in it from stock android. now some kernels do add in things that can help YOU save battery, by how you use or setup your device, but they just wont save you battery on their own. well, they will, buy not enough to notice. unfortunately @SoulSherpa, many people have tried to prove me wrong over the many years ive been with android, but none have. just because people claim better battery with one rom over another, doesnt actually make it real. people believe many things, much of it is not true.

its not different from mine, its different from 99.9999% of all other users.
i typically use under 50min a MONTH, under 200 texts a MONTH, and data, well im grandfathered so thats nothing to discuss.
how others use their phone is representative to how the manufacturers design them, for the average user who charges daily.
you appear to perceive my previous comments as sarcastic and statistical, the further could be from my intention.
i have a rather extensive android knowledge from helping other users for about 5 years. your expectations of any device are highly irregular.
we are merely attempting to make you aware of that, however unsuccessful at the moment...

The reason people treat your question like its weird is pretty simple:
While with minimal and careful usage phones can get through multiple days of usage, the battery life your suggesting, on any android phone, is going to require very little screen on time, limiting the hell out of its data connections, ect...
If you are seriously just trying to have an emergency phone that you can make calls on occasionally and fire up a terminal to remote into your server to check status or run a command or two.... Why are you paying for a 6inch screen with ultra HD display, a powerful processor, dual front facing speakers.... All this stuff that only serves to drain battery and add weight if your not using your phone for entertainment.
Your looking to pay extra for specs you don't need on a device with only "adequate" battery life instead of getting a modest phone that won't consume as much, with an external battery case that would probably let it run a couple weeks for you....

my nexus 5, without sim card, in airplane mode, brightness all the way down, can last me around 3 weeks. but, thats with 0 use. 6 days, with a nexus 6, should be possible, even easy enough.

Because larger screens make remoting much, much easier. Especially when it's a GUI. So, a "phablet" sized phone has always been appealing.
Further, I've been waiting for a "good deal" and the price dropped to $350. My m7vzw had its radio neutered (thanks Verizon), so when I switched to Ting (t-mobile) GSM my data speed hit the floor with EDGE only. The Nexus 6 has nice radio band support.

Have you considered a small tablet? (7 inch or so). You could set up a Google voice account and do all your calls/texts over WiFi/cell data. You'd get a far better battery life with far less effort to do so, and itd be even better for remote access.

I have, and you make a good point. But I still want something I can holster since I don't normally carry a man-pack or utilikilt
This Nexus 6 is pushing it for size -- the holster is huge. But the screen real estate is nice.
FYI, I'm currently running CleanCore:
http://forum.xda-developers.com/nexus-6/development/rom-cleancore-vomer-100-lean-stock-03-t3059199
...and I seem to be on-track to meet or exceed the six day goal with my light usage (email checks and texts throughout the day, occasional remote, occasional surfing, occasional phone call).

My nexus 7 fits in my pocket no problem. And I'm a fairly average sized male.

How much of a concern is the battery life (specifically, SOT)?

Hello everyone!
Background (less important): So, I've been looking at getting a Oneplus phone for a while but when my last 2 phones died back to back, I got an S6 from insurance. Problem with the S6 being just about everything (no SD card expansion, no removable battery, no rooting abilities, etc). I've been keeping an eye out for the right time to get a new device and, now that my device memory is full, I'm looking at a new phone.
I was looking at picking up either the S7 or the Oneplus 3T. The S7 is under $500 on amazon, which is pretty surprising (thought it would be much more expensive), has expandable SD card support, pretty good battery, good camera, lots of RAM, etc and they just got the ability to root. It also has some cool options like medical sensor stuff, etc (not all that important, just extra bells and whistles).
However, the 3T appears to have a very active rooting/mods community, and overall, many people have said this is the best phone they've ever had so I'm leaning towards picking that up. The only downsides I've seen/heard are the camera on the 3T isn't as good (definitely not the end of the world, it's still an upgrade from my S6) and I've seen a number of battery drain threads and that genuinely concerns me. I understand that those with the issue are likely going to be a lot more vocal than those that have everything working but I was hoping to gauge how much of a concern this really is and if anyone has determined the cause of the battery drain and if there's a solution. What I don't want to do is get a developer friendly phone that dies super quick (I understand it charges fast too but I don;t want to rely on that).
Anyway, this is kind of an important decision for me as my goal is to keep a phone for 3 years so I'm looking for a phone that is pretty well future proof (for a while, I know 3 years is a long time in the technology field) and I don't want to "settle" for a phone that's going to give me nothing but headaches.
If you guys could help me understand how big of a deal the battery drain is, it would be greatly appreciated! Thanks!

Okay here's the deal. You're posting in the Oneplus 3T forum and people are clearly going to be biased, you're lucky I'm coming from a Galaxy Note 7 and my girlfriend has an S7 Edge.
The experience you're going to get with a Samsung is far richer in features and the camera is superior. The phone just yells premium out of it's every part. The microphone will record your voice better as well.
However, if you're looking for a future proof phone the Oneplus 3T is clearly a winner. People are crying about drain and SoT simply because they're more pretentious and pay more attention to details than Samsung users. All Android phones have some sort of drain and with time, stock ROMs get more laggy and battery consuming. The advantage you have on oneplus is that you can apply all sorts of custom ROMs, kernels and mods to squeeze out the most of your battery, while on Samsung you're more prone of getting stuck with drain sooner or later.
Here's where OP3T's top card comes, dash charge is amazing. At this point I don't even care about SoT since I can charge my phone to 60% in 30m. I'm getting 4-5 hours of SoT without tweaks and 4G always on data using stock ROM. Who even wants to stick their eyes in the phone screen for more than that?
You can't go wrong with the OP3T unless you're willing to wait for the next oneplus.
Bottom line, the drain people have been experiencing on OxygenOS 4.0.3 is of little concern, especially since it's improves with Beta 12 7.1.1. Stop overthinking and get the phone you like.

So just to be clear, you're saying that the battery drain people are experiencing is likely related to a version/rom/etc that they are using and they're too lazy to try different things to try and optimize it but even if I am that lazy, the dash charge still works well enough that it shouldn't be an issue for most people (assuming you're near a charging socket), is that a pretty good synopsis?
Just want to understand if you believe the issue is user error (not using the right software components/settings), user pickiness (IE they're perceiving a problem that's not really there) or if there are the occasional phone that experiences battery issues but it's a very small number.

I think that that's what he wants to tell you. To myself : I have the 3T since yesterday and since I'm coming from a M8 it's a huge upgrade for me. But for your comparison : my brother has the S7 and plenty of my friends have the S7E. S7E is in my opinion a superior phone in terms of camera, mic, display, waterproof .. etc. All the things that make the S7/E more superior is only because Sammy has done a better job, BUT what they didn't was to make the phone future proof. The thing with OP3T is that it also does/contains all of the superior things, it's just not that good. The camera is fine for me, I don't care about waterproofness, a 2K display is nice but you won't notice the difference anyway except for the brightness if you compare them both side by side. I'm pretty sure I've made my point.
Now for the 3T's battery drain : I was still on OxygenOS 3.5.4 because I didn't felt the urge to update. Woke up at 7 AM and plugged it out, somewhere between 10 - 11 AM I was on something like 27 percent. It was somehow strange but ok. Now that I couldn't resist to flash CM13 I've noticed a HUGE difference. I flashed CM13 at around 5 PM while I was charging it (was at 90% at 5PM) and now after 4h of using it I'm at 68%. Huge differnce no doubt and I'm staying at CM13.
Hope I could help you

Thanks for the advice, particularly about the future proofing. I honestly don't get why Samsung hasn't moved to a USB C connector yet . . . Seems like a no brainer, that's clearly the direction everything is heading.

Yeah, that's my opinion based on experience as a former Oneplus One, Samsung Galaxy Note 7 and current Oneplus 3T user. People mostly started complaining about drain with OOS4.0.3 (latest current stock) and it will definitely be fixed with OOS nougat 7.1.1. This "battery drain" stigma that you're currently placing on the OP3T has been placed on all major flagships at some point. I can't be certain how well this device will be officially updated in the future, or how the battery will hold up after many many cycles, but i can assure you it will hold up better than an S7.

They did have USB-C on the Note 7. At the point of S7 launch it wasn't that widespread.

I'm actually really glad you mentioned that because, you're right, I have definitely experienced various stages of battery drain between updates on Samsung devices except I didn't get to choose when or if I wanted to update with those. At least I'll now be in control of those things! Made up my mind, ordering the Oneplus 3T now! Thanks!

I am certain you won't regret getting this device. Let me know if you need any help or have any more questions via PM.

6-7 hour of sot per charge every 22-28 hours.

technology is weird. people can get battery drains for all kinds of reasons. google services may be a reason. or some wakelock by some random app that never was a problem, but after installing it on a certain rom on a certain phone it suddenly is a problem. and weirdly enough you are the only one experiencing it. it might be something with the rom where a factory reset may help. some people go ahead and flash another rom and then it is gone. sometimes they make the wrong conclusion that it is the roms fault. or the kernels or whatever. it happens on every phone. just go to a random phones forum and you will find threads with people complaining about battery drain. and they will be the only ones with this particular issue. the vast majority of users does not have such issues. if they do you will find out about it soon enough and after some time there will be an update that fixes it.
my sot is around 5 hours depending on what i do. using media like movies gives you more screen time, heavy gaming gives you less screen time.
