Battery, APN, Charging and Locking up issues found on recent trip...Info/discuss... - Venue Pro General

Hey everyone,
So I *JUST* walked in from a 7.5 hr drive from Kansas back to Colorado from a family visit, and I have some info that might be of use to some people. Here's some of my observations:
First: Battery! Coming home today, I had the phone aux'd into my car through 3.5 mm, and listened to podcasts and music for the entire trip. Additionally, I had about 45 minutes worth of call time, about 20 text messages, and two email accounts (one exchange, and one gmail that checks every 15 minutes or so). I still have ~20% remaining, which is fairly impressive.
Second: APN... When traveling with my HD7 previously, I could data roam from T-Mobile, to VieraLink to Westlink to USA West (all roaming partners) seamlessly. With my DVP, I was unable to get data to work on the trip out there, even though it showed I was syncing with either GPRS or their EDGE networks.
I hunted around the net, assuming that I would have to change APNs for each network, but luckily, I just "added" the epc.tmobile.com APN, and it worked for all roaming networks across the states.
Third: Charging! This was a big one...I have the Monster Travel-Go USB outlet for my car, and it worked with my HD7 flawlessly. I was able to stay completely charged for the entire trip...on the DVP, however, it looks like it's a little more power hungry. I noticed that the power was slowly dropping, despite being plugged in, and showing the charging symbol. Also, I don't think the power management is very good on WP7 yet, as when it got down to around 25%, it actually power cycled while plugged in. I was able to reproduce the power cycle as long as I had it plugged in to that charger - when I left it unplugged, the phone continued to operate from 25% down to 0...Was very strange. I actually had to spin down my harddrive and use my laptop as a charging device for the remainder of the trip.
I was going to try and pick up the Griffin 1amp USB plug in a couple of days and retry the experiment - but just as a warning, not all car chargers might work with the DVP! (reminds me of the old power-hungry blackberrys days)
Fourth: Freezing! This one is a little more finicky, but I was somehow managed to get the phone to lock-up and require a hard reboot on two occasions! Both times, I was multi-tasking by listening to music, and flipping through the tiles. The first time I didn't think much of it, and just rebooted quickly, but the second time was on the trip home, so I had plenty of time to sit (and I was listening to a podcast, so I let it continue). The device was completely unresponsive, although it continued to play the podcast for another 1-2 full minutes.
There was a notable hiccup - I had just flipped back to the homescreen from the People app, and was getting facebook updates. When I came back to the main screen, where the icon would normally rotate through images, the entire icon filled up with 9 complete (sub)images, which I've never seen before, almost like it was a software glitch (possible infinite loop programming error?)
Anyhow, I know there's a lot of discussion about whether people should get the phone, so hopefully some of this info helps!

Quick question - when you were roaming on the DVP, did it show the standard triangle "roaming" symbol? I'm roaming in Canada right now and it isn't showing that.

What a coincidence, I too traveled from Colorado (Denver) through Kansas and Missouri to Arkansas. I started a thread on the charging issue.
The following things happened in both car and in the house with variety of chargers (I didn't take the DVP chager). I tried the iPhone charger (1A), the iPad charger (2.5A), a dual 1A (each) charger, and then a 1A G2 charger.
1. The phone switches off when you plug it in when the battery is below 25%
2. When you get it to charge, it reaches 100% and then it keeps draining. Like I plug it in @ 80% (it starts charging) then after 6-7hrs (night) I see that the battery is @ about 25%.
3. I the car, it never managed to charge it more than 25%. It was plugged in with nothing on.
Since no one else seam to have this issue, I'm planning to return the phone and see if it's this particular units problem.
one Q, did you get the phone from the MS store?
( powering off as soon as you plug it in when batter is below 25%)

So strange...You would think they would have some better power management than to suddenly shut off...
No, purchased directly from dell, labeled 12/15/2010.

[Q] Help with DVP - won't turn on

Hello. I created this account so I can finally ask some of my questions regarding this phone. I've had it since the January 6th shipping, and it's really been fine for the most part. I've the 8 gig version.
Anyway - within the last few weeks my phone has been refusing to charge on random occasions (it's really very random as to when it will charge and when it won't) - both plugged into the wall outlet via the USB power converter that came with my phone and plugged into my computer.
It's been pretty annoying, but nothing I couldn't work around. It would charge eventually.
However, last night I plugged it in to the outlet and it made the noise confirming it was plugged and started charging. This morning, I unplug it and it's non-responsive. It doesn't respond to anything. I have tried:
-turning it on with the power button; holding it down for an extended period and releasing
-taking out the battery
-plugging it in to my computer (which didn't recognize anything being plugged in)
-plugging it in to a different outlet with a different cable (phone came with two)
I've let it sit plugged in for three hours now and retried all of these things and still nothing... it's dead!
I'm not sure where to go from here? I guess I should have my husband call Dell.
Has anyone had any trouble with the sporadic charging?
Are there any solutions I've missed to get my phone to turn on?
You say you've let it sit for a while, was that plugged into a power source? Try that, it sounds like your battery has gone completely flat and probably needs to sit on a power source. Failing that definitely call Dell and get a replacement battery and charger and see if that fixes it, sounds like one of those items is your problem.

Yes, it has been (and still is) plugged in that whole time. I edited my post
Yeah, something is wonky, I just cannot pinpoint it. My husband's will sometimes not charge, too. But, much less often than mine does.
charging issues
In the last 2 days my VP freezes while charging overnight. Restarts when I take out and replace battery. It will also freeze when I try to use any app while charging. I tried to use Dell chat to resolve issue but got bounced around. I even had an agent tell me my service tag wasnt valid. I'll try to call 800# when I have a free hour or so (I'm sure the call will take that long). The first two levels of support at Dell seem to have no clue regarding the VP it's very frustrating. P.S. what happens with all the apps I've purchased if they need to replace my phone?

Have you swapped batteries with your other DVP? Maybe replacement is the only option, hit up @dellcares on twitter, they have helped me in the past and bypass the whole waiting on hold nonsense with dell mobility.
@tbvnz: all your purchased appls will be reinstalled automatically if you installed them via the Zune software on your pc. The ones installed via the phone can be reinstalled from the MP on the phone, just hit the Buy button again and it will tell you its already been purchased and allow you to download it again.
Update:
I snagged my husband's battery and put it in my phone. My phone immediately came on and is now functioning. My computer recognizes it as being plugged in and it's charging.
And, my battery in my husband's phone works fine. It is fully charged and his phone is having no issues.
Certainly this is annoying (and did in fact happen to my husband a few weeks ago where his phone wouldn't respond until MY battery was put in his phone, but we chocked that up to the battery being dead {which it was}.) but at least my husband and I both have DVPs and can interchange batteries... I wonder what someone who didn't have that option would do.
Certainly confusing that removing and replacing my existing battery wouldn't turn the phone on, but my husband's would - even though both batteries are at full charge.
Thanks for the help! I'm not sure if I should contact Dell about it or not. Clearly it's subpar performance, but I've not been completely impressed by this phone in the nearly two months that we've had them, anyway.
Good to hear you are up and running. You could keep an eye on the situation and contact Dell for a replacement battery if it occurs again.
Thanks. Yep, I'll contact them the next time it happens. Anyone else had this problem??

My brother and I have experienced the same behavior on both of our phones. Most recent was his this past week, exactly as you described. It would not turn on via the power button, so I swapped his battery with mine and his booted right up. When I tried his battery in my phone it showed a full charge. That has happened to me one or two times, randomly.

I've seen that behavior in my DVP (picked it up two weekends ago) and I can tell you how to work around it.
What seems to be happening is some kind of bug when you have it connected and charging and try to turn on/off the phone. If you notice, when it seems unresponsive, the hardware keyboard will probably still light up. This is because it's actually on but the screen just doesn't get any output/input.
What I did was this:
1. Disconnect your phone from the charger.
2. Slide the hardware keyboard down so you can see whether it is lit up (on) or not.
3. Hold down the power button until the exact moment you see the keyboard go dark (off). You have to be quick because it will try to turn right back on a few milliseconds later if you still have the power button depressed, leaving it still non-responsive.
4. Wait a few seconds, and press the power button as normal to turn it on. This time you should see the Dell logo, etc. and everything will be fine.
I've gotten into the habit of either leaving it on or turning it off before I connect it to my charger (it's my alarm clock so it's on almost all the time).
Hope that helps.
my DVP won't turn on either...
Hi - i'm glad i found this post because i've had my DVP for 3 days now and its frozen about 5 times and this morning wouldn't turn on or seem to take a charge. it was fully charged when i put it down last night and this morning there was nothing.
i've stuck it into a wall outlet for now and i guess i'll just wait for it. don't know what else to do. don't know anyone else around with the same phone, so that battery swap isn't an option. pretty funny that you realized to do that and that it worked.
anyway, i feel better now that i've complained about it. thanks.
Did you try pulling the battery and then booting it up? If that doesn't work, after a pull just leave the battery in the phone and let it charge. After 20 minutes you should see it power on.
So it's continued to happen with my phone whenever I have it plugged in to the wall with the brick that came with the phone. Annoying! Basically I cannot have it plugged in next to my bed; it can only charge on my computer. So much for using it as an alarm!
I will try the power down and reboot with the keyboard out. I know what you speak of with the flashing keyboard. I hadn't tried to see if mine is flashing while the phone is 'dead'.

[Q] Hoping for some assistance... HD2 not charging/powering on properly

Ok, I'll try to make this short and sweet and we'll see what happens. I spent the last 2 hours scouring this forum (pretty much the Bible for the HD2) and some other places and I'm still kinda dead in the water.
Here's the situation:
I just grabbed a used HD2 in excellent cosmetic shape. It was from a pawn shop, for $100 cash, and the device would power up at the pawn shop into Windows Mobile 6.5 just long enough to see Sense starting to load, then the battery would complain (probably hadn't had a proper charge in a long time I'm suspecting), then it would go into the "Goodbye!" routine.
Fair enough. So I get it home, and they included the HD2 USB adapter/charger, and I have my own 100% working microUSB cable. I verified the charger works by attaching it to my microUSB cable and then plugging it into my current phone (a cheapy LG 900g on NET10) and it works fine, no issues for power or data connectivity.
So I unplug the cable from the LG, plug it into the HD2, and attach it to my Belkin USB hub (powered, with nothing else attached to it, no other USB devices) and after a few seconds I get the orange charging light on the HD2. Note, it's still off, I didn't turn it back on after it shut itself off. So I let it charge for a few minutes, then I realize I should probably be better off using the actual dedicated HD2 charger, so I unplug the USB end from the USB hub, the orange light obviously goes out since it's now without that source of juice, then plug it into the HTC USB charger and...
Nothing. Absolutely nothing. No orange charging light, no response when trying to power the HD2 up, absolutely nada. So now I'm frustrated. I disconnect the USB cable from the HD2, take off the back cover, remove the battery, wait about 1 minute, reinsert the battery (leaving the back cover off), attempt to power it up, no luck.
Plug the charger back in, and I can feel]/i] the tiny vibration motor just kinda "tick" ever few seconds; there's something going on in there, I'm certain. Repeat the unplug/remove battery/wait a minute/put it back together/plug it back in a few times, and then I get something:
The HD2 will vibrate and the screen will light up with the "Stick Together" graphic, for about 1/2 second. Then it's off again. Then it's on again, and off, and on, and off. It's a loop of some kind, but it's random. Sometimes the on/off happens every few seconds, sometimes it's 10, 15, 30, sometimes a full minute goes by before it'll "flash" then nothing again.
Now, the whole time this occurs, the orange charging light never ever comes back on again - it has not come on again regardless of whether I'm plugged into the USB hub or the HTC charger, it just doesn't light up anymore, so my current suspicion is that the battery itself is simply so "dead" it won't accept a charge of any kind - at least that's my current hope, as odd as that sounds. I can get a new battery, of course, it'll just take a few days to get one (ain't paying full price here in Vegas, will order something online).
I'm stumped. I check the contacts, they're fine, they were very very slightly bent but they're ok now. I don't know what else to do since it does seem like the battery could be the culprit. It'll sit here and just flash every so often - it's been plugged into the HTC charger for the past 30 minutes straight but, I'm not even seeing the flashes anymore (the past few minutes I've been typing this post).
Maybe the battery is to blame, I don't know, but I'm hoping that someone can say "Yes, that sounds like a completely toasted battery to me, get a new one" or whatever.
Any opinions? Anyone seen this particular behavior before? I do a search for "reboot loop" and what I find are people with HD2's that get stuck at the "Stick Together" screen and, well, that's not what's happening here - it shows that, for a 1/2 to 1 second on occasion, then nothing. The vibration motor kicks in when the flashes occur, as well.
It's like it wants to fire up but just doesn't have the power to do it - and since the charging circuit isn't kicking in (no orange light), well... that's my guess.
That's about it. If anyone has any advice, I'm reading.
Thanks, and have fun, always...

Do you know what short means? p joking, just next time don't make it too long)
You won't get replies if your question is too long, because they won't bother reading it .
Anyway, back to topic.
Your battery has no juice, and for some reason the HD2 automatically boots when (no juice in battery and plugged into charger) .. you need to unplug cable, remove battery, plug in cable, wait for a minute or so, insert battery .
Firstly try the above which should stop the phone trying to start,, but two other things, firstly the battery pins bend real easily, so since you've been doing a few battery pulls, keep checking them. Second, a really REALLY discharged battery may have so little juice it wont start charging , in which case you can try the 'bare wire USB Lead charging method, where you get an old mini /micro USB lead, cut end off, bare red and black ,red to + black to - on the battery, into wall charger for around a minute, back into phone, real USB lead in, and hopefully it now has enough chrge to start booting and charging properly.
Turned out to be the battery itself - went back to the pawn shop, took the battery from the one I purchased and placed it into a known working HD2 still on the shelf (another as-is item) and attached the microUSB cable and charger, no dice: same exact issue.
Took the battery from the second HD2, put it into my HD2 that I purchased, attached the microUSB cable and charger, wham bam we're cookin' with fire now.
So I paid the guy $10 to let me swap the batteries and keep it hush-hush (I'm in there all the time buying used busted stuff anyway), came home, gave it a full night's charge and so far so good. Got NexusHD2-Gingerbread V3.0 NAND by tytung on it in about 10 minutes, and it's smooth as silk so far.
I appreciate the responses, thanks.

[Q] Boot problem I can't seem to find a fix for

I've seen a few people with the exact same problem around the web, but no one has ever posted a solution (if they ever found one).
The kids were playing Angry Birds on the Nook before dinner, when I went to turn it back on after dinner it wouldn't boot (was working when I put it down).
When I plug it in the wall charger the light is always green.
When I plug it into a computer USB port it is momentarily detected as omap 3630 instead of Nook Color like it used to, then windows reports that it's been disconnected.
It had been running CM7 for a few weeks off of emmc, but now I can't even get it to boot from a uSD card into CWM.
When plugged in (computer or wall charger) I can see the backlight turn on and off every few seconds.
No combination of button presses seems to have any effect (power, power+n, power+n+vol+, etc.)
Try holding the power button for a full minute... release and try turning it on again... see if that don't do it.
Thanks for your reply.
I wish that worked, but I don't even see the back light flicker on for a split second unless it's plugged into the wall or a computer.
It's a shame too, I got it as a Christmas present from the wife and our toddlers really loved to play the games on it. They keep asking where "bad birdies" went
Your problem sound similar to an issue I had with charging. I has a bad charger/usb cable. Its a known issue and BN will replace it for free. If you are registered, call BN support a request a new one. I have done this twice. Once when the end bent and a second time when I had a green N but not juice (just flicker and/or a 'plug in the charger' symbol). The NC requires more power than the typical usb charger/cable setup, thus spares usb chargers AND cables around the house do not work.
I hate to do this because it was so maddeningly frustrating to see the same thing posted in the thread about boot problems here and elsewhere, but it turned on today and I have no idea why.
I'd been messing with it for a few days and finally after an unsuccessful morning I left it on my dresser. I was in the kitchen making hot chocolate after playing in the snow with the kids when my two year old comes walking down the stairs with the nook and drops it at my feet. When I went to pick it it, it was in the process of booting. Whether he had done something to it or the short fall jarred something that was loose I can't say, but it now seems to be fine.
It had about 50% battery and the lights on the charging cord now respond like they should.
I have no idea what happened, but I wish I did so I could help others in my boat.
Still could be your charger/usb cable. When the charger/cable start going bad, it takes for ever to charge. Like all day just to get enough juice to boot up. If it dies again and doesnt reboot after its been on the charger for a few minutes or you're only getting a partial charge over night, its the charger and or cable.
It charged fine overnight.
There definitely must be something loose on the inside. If I give it a fairly significant whack (nowhere near a punch, but harder than a tap) it will reboot. I think it was a refurbished unit. The newer units seem to have serial numbers where the first four digits correspond to the year. The first four digits of this one are 2004! Looks like they never fixed what was wrong in the first place.
You just ran it too dead. It won't power on until it's established a decent charge first.

Battery - Charging being inhibited

Have searched the forum and Google and haven't found anything yet. Usually good at performing obscure random searches but not this time. First off, I am running stock rooted 4.4.4 NI2. Running xposed and wanam but haven't found anything pertaining to my dilemma there either. Onto my issue...
I noticed after I got the phone a couple of months back that it wouldn't be at 100% when I woke up. Usually would be around 97 or so... No big deal. I tested chargers (my wife has/and had an s5 before I purchased mine) and cables with no real difference that I could see. I figured it was some type of protection built into the phone so when it achieved a full charge, it would stop charging until needed. I was perfectly fine with this, but that wasn't the big issue. I have also noticed that if I plug my phone in to charge and end up having to move to another outlet or get into my vehicle, when I plug it in again it won't charge.
The screen will come on acknowledging that it is plugged in, but it will not charge for an extended amount of time. It is almost like the phone has protection built-in so that if there is an issue with a charger/port connecting and disconnecting continuously, it will inhibit the charging until it has a consistent current. I, for instance, am about to head to the gym and wanted to charge my phone before going. It was at 13%, plugged into my nightstand charging. My wife and son got home and are going to take a nap so I unplug and go into the living room to continue charging. It was at 31% and when i plugged it back up a few seconds later it would not charge. I kept it plugged up as i was typing here and it didn't resume charging until is over halfway through writing this post. (5-10 minutes maybe? Haven't tried counting it exactly... Yet) Haven't heard or seen anything like this previously on multiple devices (Samsung, htc, 3 nexus devices, etc.) and haven't been able to find anything online so thought I'd ask here.
Also, sorry if anything isn't stated in a way to describe things perfectly. If anyone has any questions or thoughts, I would truly welcome them.
Thanks in advance.

[Q] Red Light - Charging without back?

So, I plugged my Nexus 4 into a generic car charger and it went black instantly. The battery was at about 92%. With the hope that a proper AC or computer USB charge connection would bring up the white battery icon and fix things, I stopped by an out of town T-mobile. The manager tried the button battery-reset (up volume + power for 60sec) and I googled alternatives and tried the - enter recovery by pressing those buttons for 15sec off the charger and connecting while still holding down the buttons - trick. Neither worked.
The manger seemed familiar with that and the other button pressing tricks, and said that really, my only real hope would be to reset/replace the battery, but that would void my warranty. However, although the T-mobile site claims my Google bought phone is under warranty (and I've been paying for it each month), technically, it isn't. Under them or Google (any more). So, I purchased the tools to open the phone, as well as a replacement battery. In the interim, I tried to use all the button combos and various charging connections to get it to come back to life. I *did* manage to get it charging the old battery. I know because the blinking red light turned constant for an hour or two, and the battery got warm. I can only guess that the battery was too damaged to keep the charge however, because I could never get it to turn on during or after. My best guess is that the software battery reset allowed the phone to send a charge to the battery - at least once.
After getting my tools and replacement battery, I managed to get the phone open (with great effort - I think there must be a difference between batches there). I removed the old battery connection and looked to see if I could get the charge icon with it unattached and on the charger. I couldn't. Reconnecting the old battery didn't seem to make any difference.
I was about to go through the process of prying up the old battery when I realized that you can actually connect the new battery to the board connector without getting the old one out. So I did that. Leaving it charging like that for awhile didn't do anything, so I decided to do another software battery reset and I'm letting it sit on the charger overnight. All of this has been without reattaching the back.
So my major question is - does anyone know for sure if the phone actually charges the battery with the back off? I know there are important circuits there - which seem to shut down the phone after the battery or google image when not detected (at least that's my deducement after reading posts). But are those connections also used in charging? The Qi goes though the back to the charger function, so perhaps that connection has to be there? I would like to try and find out though beforehand. It took 2 hours and two mangled guitar picks to get it open the first time, and the second may be just as trying. (And believe me, towards the end, I was not concerned with being gentle.)
I am also curious about the four prong battery connection. I've seen the post about charging the battery using external sources by connecting to the two outer pins. Does that mean the two inner pins constitute a second circuit between the charged battery and the phone? And if I find another 3.8v battery fully charged, I could perhaps connect that to the phone instead by wires and get it booted into recovery? As to why I'd want to do that, I don't recall the last dated CM version I had installed, so finding that in their folder plus pulling off everything from /data... assuming I replaced this with another Nexus 4, I might be able to save myself a lot of setup hassle.
In terms of the red light... it actually seems to be an error code. When triggered, it blinks 7 times, and on the eighth stays lit for a bit before repeating.

So my major question is - does anyone know for sure if the phone actually charges the battery with the back off? I know there are important circuits there - which seem to shut down the phone after the battery or google image when not detected (at least that's my deducement after reading posts). But are those connections also used in charging? The Qi goes though the back to the charger function, so perhaps that connection has to be there? I would like to try and find out though beforehand. It took 2 hours and two mangled guitar picks to get it open the first time, and the second may be just as trying. (And believe me, towards the end, I was not concerned with being gentle.)
I am also curious about the four prong battery connection. I've seen the post about charging the battery using external sources by connecting to the two outer pins. Does that mean the two inner pins constitute a second circuit between the charged battery and the phone? And if I find another 3.8v battery fully charged, I could perhaps connect that to the phone instead by wires and get it booted into recovery? As to why I'd want to do that, I don't recall the last dated CM version I had installed, so finding that in their folder plus pulling off everything from /data... assuming I replaced this with another Nexus 4, I might be able to save myself a lot of setup hassle.
In terms of the red light... it actually seems to be an error code. When triggered, it blinks 7 times, and on the eighth stays lit for a bit before repeating.

I RAN INTO A SIMILAR PROBLEM
I found that holding the power button for a while allowed my nexus 4 running stock Lollipop 5.1 to boot back up.
Have considered that you may have a faulty USB port ?
Just pop the old battery out install the new one plug in the charger and it will charge. You can boot up without the back on. The back contains the antennia.... and the NFC circuit board.
Good luck

Well, still no luck. I ended up putting the new battery in and closing it up to try the Qi charger, but all I can get is either 7 or 10 red blinks followed by a short solid light. No white battery charging symbol or anything else.
When you say a faulty USB port, what are you referring to? The cable works (though I've also tried my Nexus 7 one too) and even though it won't boot, my computer does recognize that something is there when I plug my phone into it (it just can't figure out what's plugged in - which is normal). I want to say that it's trying and failing to charge the new battery. At this point, I think the charger messed up more than just the battery.
