[Thunderbolt General] OdinGuru:
Thanks for the suggestion.

If you look at the last part of my post under the "Variation Testing" heading, I believe I did try a number of configurations with LTE off. Each case where LTE was off I saw normal or low power consumption. This is why I grew to suspect the LTE radio in the first place.

The technique I used for switching between 3G and 4G modes was actually the "Set prefered network type" drop down on the "Phone info" menu that can be reached using "LTE OnOff" app, "Network" app, or by dialing *#*#4636#*#* and selecting "Phone Information".

I have used the dial ##778# to get the ESPT menu before, but that was to modify the "Rev. A" setting from "eHRPD" to "Enable" as a work around to re-enable 3G EVDO during the few days of nation wide 4G LTE & 3G SVDO outage we had a month or so ago. BTW, it looks like I had by phone set to the non-stock "Enable" setting rather than "eHRPD" for the original data capture. I switched this back to "eHRPD" and I'll report if I have the issue again. I was last playing with this setting to see if had any effect on the random reboots after the OTA while on 3G, but it did not.

In the ESPT -> Modem Settings -> Preferred Mode drop down I only see the options for:

- Automatic

- HDR Only

- Digital Only

- CDMA Only (selected by default)

- CDMA HDR Only

There is also a a Preferred Mode(9k) drop down that has these options:

- Automatic

- HDR Only

- LTE Only

- HDR LTE only (selected by default)

I believe that these are settings for the voice radio and the data radio respectively. See the third page of the excellent Anandtech review of the HTC Thunderbolt: <Sorry, I am a new xda-developers forum member so it won't let me post external links yet.>

Do you have suggestions on how to set these? I am unfamiliar with the HDR acronym and haven't turned up anything that seems relevant in my Google searches.
[Thunderbolt General] OdinGuru:
I had another instance of the 4G LTE power burn issue today. I tried a few of the above suggestions.

I enabled WiFi and logged on to an access point. This did not stop the abnormally high power burn. Instead it went up slightly; I assume this was the extra power for the WiFi radio.

I also tried turning off Settings -> Wireless & networks -> Mobile networks. That resulted in the 4G LTE icon going away but the signal bars were still showing. I couldn't use the Internet but a SMS came through in this mode. This mode did not stop the power burn either.

The burn stopped only when I rebooted.

The reboot happened when I dialed ##778# to get the ESPT menu and switched the "Rev. A" setting from "Enable" to "eHRPD" and this time remembered to commit the changes (forgot to when I posted above). Committing the changes auto-rebooted the phone, which returned me to normal power consumption. I will report if I have the problem again now that I have confirmed I am back in the stock eHRPD mode.

Most of today I was in very good signal conditions, judging by the time the drain started, I could have been out on a errand in the neighborhood. So I can't 100% guarantee that the 4G signal was high the whole time.

Does anyone know of an app that works on the Thunderbolt that can log signal strength over time and preferably graph it too (e.g. similar to Battery Monitor Widget). I have tried to download and use a few without success including: Open Signal Maps, Network Signal Info, RF Signal Tracker, and Signal Finder. Some of these apps didn't work at all (I suspect 4G signal is reported a bit differently and this confuses some of them). Some work in general but I can't seem to get the logging I'm looking for.

Thanks!
[Thunderbolt General] crpalmer:
By disabling data, I was actually using the notification tools in most rooted roms. That should be equivalent to what you said.

Toggling airplane mode toggled the battery drain problem until it failed to enter airplane mode and I had to reboot.
[Thunderbolt General] mcargil05:
I see the same thing

Where I live at home we only have 3G at work I have 4G. The phone will get itself into some kind of mode at work and burn through the battery in 4-5 hours. So I keep it charging on my desk all day. If I didn't, some days it wouldn't make it till lunch.
[Thunderbolt General] agdaniels:
You are absolutely correct on all three points, my main focus with the two suggestions were background data for the factory reset and faulty hardware for the replacement.

If you have the ability to disable all background data syncing while on 4g- on the application side, sense ui side, and the android side you could completely rule out software being the cause. My thoughts with this are some background service is keeping the radio active, causing the burn.

The replacement device would help to narrow down whether the issue lies on the device side, or if its more related to the towers/the way lte functions. The latter is bad news for you. My thoughts on this are that some people report no issues running lte, while others are having similar problems as you have reported; I doubt that it is faulty phone hardware, but its possible.

I share your conclusion that this is a firmware(baseband) issue. Actually going in and manipulating it would require root, a considerable understanding of how the interaction between hardware and software works, and the abilty to make tweaks and test them. I will also contact some people more knowledgable then myself and see if they want to chime in on the matter.
[Thunderbolt General] OdinGuru:
Excellent idea. I then I was able to execute the test you suggested yesterday when I re-encountered the issue. I saw the exact same behavior you reported: even though I disable applications data over LTE, the drain did not stop. This is strong supporting evidence that it is not an issue with some kind of rouge app / sync settings.

Drain toggling with airplane mode is the exactly consistent with my observations as well. Sounds like we have confirmed you having the exact same burn issue.

Thank you for the feedback and confirmation.
[Thunderbolt General] OdinGuru:
This is consistent with my observations of the burn issue. The baseline power consumption I observed is about 20% of the battery per hour while phone is idle with screen off. That would correspond to the phone burning through a full charge in 5 hours even if you didn't use it at all. Add any extra actual usage on top of that and 4-5 hours of life sounds very plausible. That assumes you have the problem right away though (the worst case).

I typically see a variable amount of time of normal consumption before the issue starts. For instance, let's say I've been running normally for 3 hours and am at 80% before the issue starts. Then I'd quickly burn through the last 80% in 4 hours or less. In that case I'd get less than 7 hours of total battery life (e.g. not making it through the day). If my normal usage had continued, it should be more like 15 hours (e.g. more than enough for a long day and needs charging every night).

There is still the question if this issue is related or not to 4G signal levels. What do you normally see in the office? Number of bars is useful, and also the more detailed dBm number can be found in Settings -> About Phone -> Network.

Thank you for your report.
[Thunderbolt General] OdinGuru:
In the most recent test I disabled "Mobile Networks" which effectively shutdown data service. I also tested switching to WiFi which should have redirected all data away from the 4G LTE radio. Neither one of these stopped the power burn. Do you agree this is sufficient enough to rule out apps/services?

I noticed on the Phone info screen there are some counters for number of bytes sent over the radio. Next time I have the issue perhaps I'll keep track of how those change when I'm having the issue vs not.

I agree that trying replacement HW would be a useful data point to help identify if the issue is inherent or tower related. I'm not quite ready to jump through all the hoops with Verizon to do it myself yet. I'd want to root first to create a backup of my current setup first to reduce the pain of the procedure. And I'll probably give them the benefit of the doubt and wait for the next OTA to give them another shot at fixing the issue with FW.

Part of our questions would be answered if there was indeed a user out there that runs 4G LTE and can document that they do not have this issue. Does anyone out there run Battery Monitor Widget or similar and can say they have never seen the tell-tail pattern of power burn I am talking about?

I really wish Android had a built in screen capture feature. I need to get adb installed and setup on my computer so I can post examples of what the graphs look like; I think that would help other users to identify the issue as it happens so they know when to re-boot to save what is left of their battery.

I agree there is very little we as users can do to fix the issue if it is in the radio FW. As you say, it would indeed take very detailed knowledge of the HW. Also, I think it would be impossible without the radio FW source code. Although I haven't looked through the HTC released code, I would be very surprised if this was included. It wouldn't be covered under the Android or Linux open source licenses as it likely originally came from Qualcomm and is considered proprietary. Without that, we can only hope that Qualcomm/HTC/Verizon work together to get it figured out. The good news is that they all have a good business case to do so. This LTE chipset is likely to be used in several phones so they need these issues resolved before it affects their whole lineup.

Anyone know if the new Samsung Droid Charge has this issue too?
[Thunderbolt General] alexdw369:
After experiencing all the same issues myself, I have noticed that this seems to have been addressed in the leaked Gingerbread radio. Might be worthwhile to repeat testing using that radio and then somehow compare code.
[Thunderbolt General] agdaniels:
I would have to agree you've sufficiently ruled out software, the point about the gingerbread build not having issues is worth noting though. Can someone confirm the 2.3 release has new radio firmware? It wouldn't be difficult at all to pull it out and flash it if it does

My thunderbolt will be in hand Monday, I don't have the phd you have in c.s (mines just a bs) but I've been in the business long enough to throw some graphs together. We'll compare notes then if we don't find resolution sooner.
[Thunderbolt General] AndroidGraphix:
I experience the same problem in North Phoenix when running 4GLTE in a weak 4g signal area. It doesn't happen too often if I'm in a heavily blanketed 4g area.

EDIT. I'm running rooted. OC to usually 1400 mhz. I'm constantly being synced with the Exchange Server. My phone gets super hot when running navigation plus 4GLTE. Temperature gets up to around 110 degrees Fahrenheit.

When I notice my phone heating up, I'll switch to CDMA prl and immediately my battery temperature starts dropping to normal levels, ie. 86 degrees Fahrenheit.

At the time I was running on different radio combinations. Such as, CDMA. 6 and lte. 7 radio combo. I have recently switched to Gingerbread so more testing is needed.
[Thunderbolt General] agdaniels:
Had a spare minute to look up the radio, looks like its bricking certain devices after flashing. Not completely ruling it out, maybe you can flash it, test it, then flash it back, but there is some risk involved.

Whatever the case, its reassuring to know updates are coming eventually.

[Thunderbolt General] 1454:
I experienced the same issue when I was still running stock, nonrooted. It always happened when I was at home, where I stay in the -82 to -88 range in signal strength. I posted a question on it both times I had the issue, but never saw a response. I haven't had the same issue since rooting and flashing. However, I am now having the issue of no 4g data at all. (recently occurring issue) I have a replacement coming and will see if this fixes my issues.
[Thunderbolt General] videoeditman:
I've been having random massive power draining also! A while back I installed an APP LTE On/Off, Then I select CDMA auto PRL - 3G only. I believe I've still seen the massive power drain once or twice since running 3G only. I live in a 4G network area. Occasionally I'll switch back to 4G to use USB tethering to my computer. I'll try to keep a better watch, I'm running Current Widget App, when it happens it shows 250-400ma drain. I think more people have this problem than know it!
[Thunderbolt General] dcsr23:
I've experienced this issue as recently as today, and have had it occur several times (non-rooted, and after OTA). I've also had occasional 4g lock ups on my device where despite having 4g signal, I'd get no data even after several reboots. I assumed my device to be defective and ordered a replacement to which I'm getting ready to switch to now.

Although I have no CS degree, my theory is that because of the dual radios (LTE and CDMA) that somewhere the LTE radio possibly gets locked into a power consuming state possibly when trying to amplify signal as I've noticed it usually occurs at my house which is on the border of an LTE coverage (the front of my house carries 2-3 bars of LTE, while the back half seems to sit at 4-5 bars 3g). I've also had it occur at my office as well, which is in the heart of 4G coverage in Phoenix, AZ.

I'm wondering if it has something to do with a radio hand-off. I'm interested to see what you more qualified people come up with.
[Thunderbolt General] AndroidGraphix:
It's bricked about 4% of people surveyed and it appears to only have happened upon the initial release. I'm running gb just fine.
[Thunderbolt General] AndroidGraphix:
I've never experienced any rapid power drain while on CDMA prl. If the problem is on the radio hand off then eHPRD should be suspect. It's designed to switch the network type when there is no signal of 4g.

I'm thinking the eHPRD wasn't on or undergoing repair when these test were done. This would prove that our phones spike in consumption when they receive a signal from eHPRD to switch from 4g to 3g.
[Thunderbolt General] fupaboss:
Yeah, same here. I have the same problems as OP. When my phone is on wifi and while on 4g LTE mode and on standby i have rapid loss of battery. It lasts on standby 10-11 hours. While on wifi and on standby but in 3g mode, the standby time is over 24 hours!
[Thunderbolt General] BigMcGuire:
Same experience - I've just given up and turned on CDMA Auto PRL just because I can easily get 24 hours with the amount of standby my Bolt experiences in a normal day. I'm on WiFi 99% of the time when I need to do something data intensive anyway, so why have LTE enabled unless I REALLY need it? I'm running 3G all the time now.

With the new MR2 radio, 3G standby seems to be AMAZING.
[Thunderbolt General] Bunnywinkles:
I am having this issue too. I called Verizon and they are trying to say it is because the 4G in my area is not officially turned on yet, even though I can pick it up. I am sorry, but under no situations should an idle phone die in 2 hours. They tried to sell me an extended battery for half off but I am not doing it. This is ridiculous, I use my phone for work, and it is useless. I might as well train a carrier pigeon to communicate with my boss.

Note: HTC and Verizon both have it listed as an issue under investigation. The rep told me they have a fix but couldn't tell me a release date. He did tell me to expect MR2 2nd half of June, which we knew already. I don't know, they are suppose to call me back tonight. I am going to see if they won't just switch me to the Charge. I love the hardware of the TB but the software support over the last month has sucked, and now this battery issue. I will update you on what they say.

Also in-store reps can give you an extended battery, extra battery, (And? or?) a mobile emergency battery charger thing at half price. They aren't authorized to swap phones or any of the good stuff. You have to call corporate for that. At least that's what my buddy at VZW said. So it looks like all of us with this issue need to be heard at corporate.

Oh and this was my first post :)
[Thunderbolt General] OdinGuru:
It has been over two weeks now singe I correctly re-enabled eHRPD (see previous post in this thread). I've kept a close eye out, but I have not seen the 4G LTE battery burn bug since. I suggest anyone here who thinks they have been suffering from the same thing check their configuration for this to see if it helps them too (and make sure to actually COMMIT the change :)).

The occasional extremely high rate burn (1000 mW / 250 mA baseline consumption) has gone away, but I wouldn't say power consumption in 4G LTE is now "good". By my observations, it still eats up ~8% of my battery per hour on standby which is about double what 3G does. Switching the Rev A. mode to "Enabled" instead of the normal "eHRPD" was not a stock setup or recomended by Verizon, so I can't blame them too much for that configuration having issues (not like the reboots in 3G mode, which I do blame them for.) I'm glad to hear the reports that Verizon/HTC/Qualcomm are working on improvements and that some people have noticed better performance on some of the leaked updates.
[Thunderbolt General] AndroidGraphix:
Today was one of my worst days ever on 4g . My battery drained 65% in two hours. It said I was on lte which is strange because I'm on lte now and my battery is not draining fast or heating up. I was overclocked to 1.4 MHz but I noticed it I immediately dropped it to 1ghz. I still noticed a rapid power drain. I've switched kernels since then but I was on the latest mr2 which I've posted below.

Is it possible the rapid power drain is dependant on the signal strength of the lte.

For anyone living in the Phoenix area, I was at 48th St and Washington. Inside the f1 race track.

Also, my signal strength showed -90 . Does that have any relation to the lte signal strength?
[Thunderbolt General] cowisland:
I was on MR2 radio for a few days last week and kept the phone on 4G all that time. The burn did not happen, which gives me hope they will fix in the next OTA update. On MR1 it happens every other day or so when its on 4G.
[Thunderbolt General] idkwhothatis123:
Used 4g in Chicago on CM7. never dropped and batt life was great
[Thunderbolt General] cowisland:
Not everyone has the burn issue. I know someone on stock and this has never happened to him.
[Thunderbolt General] Bunnywinkles:
Yesterday I got my replacement phone. Only lost 15% battery while at work today with moderate usage. This is with MR1. Seemed like I didn't have 4G in places I did before though. We will see what happens with this MR2. Also noticed the phone seems faster? Maybe its because I don't have 4k texts on it though. Nothing else really noticed though. I laugh at Verizon trying to blame the battery. This is the same one from my old TB. Just new SIM and Phone. OH! I either got an extremely lightly used phone, or this was brand new just not in retail box. Not a single sign of use. No dirt, no scratches. Kickstand wasn't worn at all, ect. Still have the reboot issue, but I was expecting that. Its not as frequent now though.

Hello Guys,

yesterday i got my shiny new Nook Color and it is pretty awesome. The root process and installing Cyanogenmod was quite easy and without problems.

The only which is not working properly for me ist watching my Anime Collection. I have a lot of files (.mkv and .avi) and they have all subtitles.

I found the HandBrake presets but after the encoding, the subtitles are gone.

Is there another program,script or anything like that? Windows or Linux doesnt care.

Use the "burned in" option for subtitles (I'm assuming these recoded videos won't replace your originals) when recoding for the NC in Handbrake. A lot of players say they support soft subs but I've not found them to be reliable in finding (included in container, not separate e.g. srt or ass) subs.

Hi All,

Any can help me on this or recommend me which Camera app is compatible with touch Cruise that no need to use H/W Button to snap photo?

Currently, my phone Center round H/W button is no longer sensitive or not function well, each time want to snap photo, need to press very hard and long time and tried few times only it able to snap photo. Right now, I am looking for other Camera S/W which can replace the current 1 and that S/W just press OnScreen Button to snap photo. Anyone can help me?

Thanks.

You could try Camera_6_01_31727_00, it works on Polaris, there's an on-screen button to take shots, so hw button is not needed anymore; you just loose hardware autofocus ability (digital one works I guess), but is required only to take macro shots I guess :)

Entering Android Recovery Mode

Reading ODM fuse: 1

And thats it, its just stuck there.

Now I bought it second hand and was told it had been rooted and flashed with a kernel that allowed you to alter the CPU.

My question is how do I get rid of my data and get it booting into this recovey mode?

I've installed Rom Manger from the market and tried installing CWM but it just gets stuck again on the dual core screen.

Mine is a UK 3G model.

Any advice, suggestions would be most welcome. It does boot fine into android 3.01.

I need to get this posted out today, hence the wipe.

Thanks,
