For those who have upgraded their radio to the new leak, do you think it is better or worse than the official radio?
Worse. It keyed my car, impregnated my dog, and stole my wife.

Thats weird. For me it got me a raise a work, bought me a new car, picked the winning lotto numbers and otherwise tends to my every need.
Note: all these results were only while the phone was still on the charger. fearful of that the new radio actually requires a gas powered generator to keep this up.
with old radio i use to get full bars at work but now it shows up 2 or 3 with six bar signal icon
I know you cant base it off that but now it seems to drop all signals more often
and when i use usb tethering now for some reason it runs at snail mail speeds
but i was going to give it as much of a chance as i could before flashing back but its not looking good for me anyways
I have been running the new radio on my own ROM and it seems the same.
I would mention that this is original ROM from Verizon, not the new leak. This weekend I plan on installing the leaked RUU and trying that for a while.
Anyway, I do agree with adrynalyne, **** did key my car..
I've noticed no difference. Literally. My GPS is still broken and my battery life is still mediocre. How do you activate the "steal wife" feature?

For paid donations only sorry...
Funny, after I installed it, my phone now runs on oxygen. It actually charges on my belt clip. Also, my GPS consistently can tell me where I'm going to be 20 minutes from now.
I am running the new radio and Bamf 1.5 Debloat. I have not had any improvement in keeping 4G signal. I am in very strong coverage area most of the time and if I keep it on CDMA+LTE it will prefer CDMA. If I change it to LTE only it will grab 4G and keep it even if I switch back to CDMA+LTE. Just seems I should not have to do that.
Seems like Verizon is still having problems in my area with 4G if I even go near the border of 4G 1-2 blocks from it but still inside it drops 4G.
better battery life for me for sure sure but gps still sucks..
as far as signal, 4G signal in Houston has always been great so im not sure
I haven't noticed a bit of difference unfortunately.
GPS is a lot faster to lock on. 4G has always been stable for me, so I don't notice a difference there. Battery life seems to be about the same as before, but then again, my radio almost never switched over to 3G and that was a problem a lot of people were having on their phones, which drained battery like crazy.
No difference at all. So far.

Well, contrary to what everybody here seems to be experiencing (or not experiencing), the new radio has been an improvement for me.
The building I work in is pretty terrible, signal-wise. With the old radio, if I had the phone on CDMA + LTE, it would jump from 3G to 4G to 1X to no data all over the damn place. And the "no data" happened somewhat frequently, would last for a minute or two, and then kick back on. Kind of a pain if I was browsing web (while I should have been working).
But today, with the new radio, 4G was pretty much constant. I did see it drop out for a second here or there, but it resumed much more quickly and wasn't bouncing to 3G and 1X.
Only one day's worth of observation, but definitely seems to have helped here.
BAMF 1.5 Remix, if it matters.
With the new radio and bamf my phone sucks. Battery has gone to hell in stadby (even with all data off). 4G doesn't even work now. I even tried going back to stock RUU and reflashing everthing from the new RUU. No dice.
I'm going back to stock radio and bamf 1.4. At lease everything worked there... I think the new radio is to blame. BAMF 1.5 was running great when I didn't have the most recent raido.
my battery has gotten worse, and i cant send mms, signal has been about the same. GPS works better.
Edit : just flashed the new new radio and mms now works. We will see about battery.
On perfect storm 1.3 and the new radio has shown some signal improvement, and bettery battery life. My gps locks on within a couple seconds.

Flashed new radio and BAMF Remix this morning. So far, I'd say it's been a pretty fair improvement. GPS is dramatically faster (I used to get no lock at all, now it takes maybe 30 seconds), 4G to 3G hand off seems smoother, and battery life seems reasonably improved though that may have more to do with the ROM + kernel than the radio.
I'd have to give it a few days to make a definitive call, but over a day's usage it's been a fairly solid improvement for me.
I've had a fair improvement in GPS locks, and a noticeable increase in battery life. I have a feeling that at least some of these complaints are tied to not using the proper GPS app fix, not wiping battery stats, etc.
That being said, these leaks normally give some people headaches, which is why it's only a leak ;-)
Bolted!
I am not sure why you would root, change radios, update kernels, etc... if the end result is that the things that work out of the box, stop working. What is it that you are looking for? I had an HD2 so I get it, and I have done the whole android thing, but what is the end game?

Because it's unstable, battery life, modem sucks, no band switching, no bln, force closes render the phone useless for half a minute, the list goes on and on. It's cool to hop on ics for a bit, but it's not ready to be my daily

It seems to all come down to how good of a connection area you are in. It seems that people in low or bad connection areas experience way faster battery drain on ICS, but if you are in a strong signal strength area the battery actually seems better. Of course, this is just what I have noticed because I work in a low signal strength area (way faster battery drain), but I live in a good signal strength area (extremely good battery life). I've tried several different modems and although the rait of drain varies, it still holds true. Everbody's results may vary. I am hoping when "network switching" is introduced to ICS that it will help solve the problem.

Lower the signal more power is needed by modem to hold connection; this is how all modes work. But I do work in the area with very week LTE or even week 4G and I still get better battery life then with GB. It took few days to get batter battery life.

Good for you, glad it's working well for you.
I went back to GB earlier due to my dialer being extremely laggy, but the market place wouldn't allow me to download from the marketplace. It would go through the motions like it was going to download but then it would do nothing . Suggestions on let this?
I went back to the ICS leak and then installed the Super lite version and my phone is running amazing, but would like to know any suggestions as I may still go back to gb.

Hey not sure if im even putting this in the right thread but im very new to rom and kernel flashing etc
Im running CleanRom 5.0 and Beastmode 4.3 Kernel
My battery life right now is 30% after 8 hours...what am i doing wrong both the rom and kernel have allegedly good battery life...i recently flashed both like 2 days ago...am i supposed to let the kernel and rom calibrate etc before i freak out about the poor battery?
My screen is using abt 60%
voice 20%
standby 5
whats app 4% phone idle 4%...not sure what other info to provide but can anyone help me make modifications for better battery life
im using kernel tuner i tried governor: badass, wheatley, intellidemand..my screen brightness is veryy low i took it off auto because i felt it was sucking it even faster. I dont think im overclocking...random apps like youtube, facebook etc are running in the background is this a huge problem?
someone pls help!
thanks
What is your screen on time?
60% brightness isnt "low" by any means, I usually leave mine on 40%. You made a good choice to take the phone off auto brightness.
Personally I got really bad battery life with beastmode. I now run flar2's experimental 1.5 GHz kernel and couldn't be happier.
Radios also have a significant impact on battery life. The 2.29 radio + ril has worked best for me with battery life.

Yeah you have to keep in mind how you're using your phone. If your screen is on for a lot of taht 8 hours, that's a decent run.

Think he means screen is using 60% on the battery usage stats, not screen brightness.
60% is fairly high. I think he just has the screen on a lot. Brightness may also be a factor. Only about 4-5 hours if screen-on time is to be expected on low brightness.

Battery life
Hey guys, I've recently bought a AT&T HTC One X. This is my first smartphone, and it is fully stocked, locked bootloader and no root, android 4.0.4 and software version 2.20.502.7, really like the phone. However, I am not really impressed with the battery life. I would usually charge it over night for around 8 hours, take it off in the morning at around 08:00, take it to school, casually check facebook/gmail, maybe watch one or two videos and by the time I get home at around 15:30, the battery would be at around 15%. I was wondering whether this is normal and if there is any point of my rooting the device and flashing any custom roms?
I have disabled all the AT&T bloatware, decreased my screen brightness to around 25%, no live wallpapers, disabled auto syncing, wifi and mobile data mobile switched on only when I use it, only have a weather/clock widget and a couple of games. So I have been researching about rooting and customer roms for about a month now, and found out that some members have amazing battery life times with Cleanroms and custom kernels, so I was wondering whether the latest 5.1 Cleanrom with a Beastmode kernel 4.4 would cause any damage to my phone and whether any of you guys are using it?
Thanks for your time!

Are you using LTE? I found that my battery would drain very quickly when set to use LTE, even if I'm on wifi. I guess the LTE towers were further away or something because my signal would drop really low. I leave my phone on 4g for the most part now, only switching to LTE when I really need it, and I can get two days of battery with light usage. I've only recently flashed CleanROM so I would expect it to get better, but it's too early to tell. I've only got 22 minutes of screen time, but my phone has been on for 9 hours and it's at 85%.

Wow, that sounds good, even with that much screen time the standby is much better than on my device. Sorry I forgot to mention, I live in the UK and LTE or 4G is only available in major cities. However, my phone is AT&T and is sim-unlocked, and I get the '4G' mark on the top of the screen, therefore I think it might be the HSPA+ that is available in my area, which I rarely use anyway.
Is it the stock kernel that you have flashed with the rom?
Thanks.

Just because that person got a particular battery life by toggling off LTE, don't assume that you will get the same results. Battery life often tends to be very reception and location specific.
I leave LTE on 24/7 (as well as WiFi, and brightness on 40%), and can get close to 48 hours on a charge with low usage.
Also, bear in mind that you can't toggle LTE off on AT&T stock ROMs.

That's correct, on stock AT&T ROMs, the "4G" icon means HSPA+. If its on LTE, it will say "4G LTE".
My guess is that you are just having reception issues. Flashing ROMs and kernels may get you slight improvements in battery. But don't expect it to make a huge difference, or you will likely be disappointed. A different radio may also help.

Thank you, I will have this in mind. I was wondering whether it was due to reception or was it just the batter malfunctioning. In your opinion, would it be better to wait for the Jelly Bean update and see whether the battery life improves?
Thanks.
I have to say there are lots of thing that went backwards in the Jelly Bean update, but battery life seems to be worst. With all location services off, all maps location repoting/history off, the idle drain in low cell signal areas is terrible. Way worse than ICS.
I don't see any abnormal processor usage or wake locks. I think this means the radio is to blame.
Damn am I tired of Samsung/Android updates adding new features but making some things worse. I tried to like Android and defend it. I can't do it anymore. It's sloppy and rushed. I hate it now.
I am running stock deodex BLK3 and have had no problems with battery drain. Actually I am getting better than I had on ICS.
Only things done to it are kinda crap mods and removing stock applications. I have GPS on about 50% of the day and hardly ever use wifi.
I'm on cleanrom 5.5.1 and battery life is very good I can easily make it through the day

On on stock with Apex launcher. I'm a moderate user (browser, calls etc) and I get 24 hours and still at 30%+ Most of the time I'm on wifi as our building does not have great interior reception.
IP, download Carat app and see what is draining the battery. I assume you already used BetterBatteryStats and there were no wakelocks? Check if there are any apps that are refreshing at short intervals. The battery drain issue should not be that drastic. From my experience, I was completely stock ICS (bloat and all) until the JB update. Right now I am unlocked, rooted and debloated but still stock - and battery life is only slightly worse (VZW remote diagnostics were also disabled). If nothing else works, then wipe/ODIN to stock and see if things are different then.

I think each battery usage is different. Making your screen turn off quicker will save battery, turning off GPS will help too. I would like to know if WiFi or 4G:LTE uses more battery because with an unlimited data plan I can work with it a lot easier one way or the other.
Anybody done any research or have an inkling for one or the other?
Wi-Fi uses less power 4G uses more power, that's a fact.

I had terrible batt life after updating to JB. On ICS i would get 1% loss each hour when idle, right after the update it was more like 10% each hour. I ended up reading thru tons of posts not only for sgs3 but other phones updating to JB and having batt problems. So i factory reset and formated the sd card then put my files back on it. Then i finally found a post where it was stated that if you have a lot of media either on phone or sd the system will have to index each file, for thumbnails, quicker pinch zoom in gallery etc. That kept my phone awake and killing the battery for a good 12+ hours after the update. Today it finally ended. I am now 24 hours off the charger with 89% batt remaining, making it about .4% discharge per hour. I know this wont solve everyone's problems with the battery drain but maybe it will help some. GL!
I see a big difference for me with the battery between ICS and Jellybean rom. I was on Bean's custom stock build 15 originally and with medium - med heavy use, I see about 15-20% remaining battery after 10+ hours of use. With the new Bean's jelly rom b7, I need to charge before 10 hours with the type of same usage. This morning, I saw a 12% drain in 20 minutes for checking facebook/instagram and some email.

That's not true. If you have good LTE coverage it uses less power than WiFi. I have confirmed this checking power consumption with Battery Monitor Widget Pro. I'm losing ~22 mV every 10 minutes with WiFi turned off and pretty good LTE coverage (-100 dBm) and ~28 mV with WiFi on. When there is poor coverage WiFi will be better choice of course.

With Wi-Fi the signal is right there no sharing with millions of ppl no searching for signal, with 4g you'll use more power.I've done test with both and my 4g is great but still Wi-Fi uses less examples 4g great signal maybe 12-18hrs battery moderate use...Wi-Fi 1 day 9 hrs same usage.you do the math
Clean Romed&themed the [email protected]#out
My Jelly Bean battery issues are very tied to cell signal level. At home today, with good signal (LTE -100 dbm), I see no idle drain issues with JB. Its just like ICS. However, this last week at work with poor signal (LTE -112 dbm), with JB I had terrible idle drain. In that exact same setting ICS had no issues.
I have a feeling the new radio is doing some hyper spastic searching for better towers now around -110 dbm, where it didnt used to. If my woes at work keep up I'll flash back to ICS radio.
I've gotten great battery also on ics whether on 4g or Wi-Fi that time really didn't matter,I loved the hd radio.but on jb the lk3 is ok I do get faster gps lock.

At my workplace, I get terrible reception, as in 1-2 bars absolute max. This causes some significant battery drain (between 30-50% over 5 hours) and the phone gets very warm to the touch. I keep it in my pocket and even through the fabric, it's very warm on my thigh. Obviously this can be solved by turning the phone off or switching it to Airplane mode, but does anybody else have this issue? My first Nexus 5 that I ordered on launch day and received a week later didn't have this issue. My second Nexus 5, I RMA'd for dead pixels, and that had the same issue, as does the replacement one.

I'm not so much concerned about the reception, as it was pretty craptastic on my first Nexus 5 too, but I'll give it a try in the hopes that it'll cool this thing down. Looking at that thread, I see there are no 4.4.2 modems, so I assume older modems work fine too? Any recommendation on which to use?

Not sure how hot is hot for you. But, that's the typical behavior of the cell phone technology. When signal is strong, the cell phone will use lower power (less than 1 Watts) to communicate with the cell tower. When the signal is weak, it will draw more power (up to 1-2 Watts) in order to stay connected with the cell tower. When I was in the building with weak signal, I can see the battery drain at a much faster rate. At home with stronger signal, batter will last much longer. Recommended not to talk on the phone for a long period of time during the weak signal situation. Hope this help.
It's normal
