[Nexus 7 Q&A, Help & Troubleshooting] dbstrat:
"Show low low battery logo" Nexus 7 thinks battery is dead even when fully charged!

I have already got a replacement on order from the Play Store but since I haven't seen any reports on this after plenty of searching I figured I'd describe the issue.

My 16gb Nexus 7 worked pretty much flawlessly for the first several days of pretty light use minus very minimal flicker on occasion. As of two days ago the unit is basically unusable as it randomly but excessively decides that the battery is dead even though it is fully charged. The first several times this happened I wasn't paying attention and I thought it just shut off by itself, but then I started to watch it more closely but it also started happening more and more. As of this morning it will not stay on more than 5 minutes before it audibly notifies a low battery with the messages "Connect Charger" and "Powering down". Sometimes it will give two options "Battery" and "OK" but I was never able to actually get the buttons to respond because it would already be shutting down. Other times it will just show the connect charger and powering down messages with no buttons which is strange, but in either case the device shuts down.

Once I started troubleshooting I figured out a little more information.

Watching the lock screen while it is charging I will see it go from it's (I think) correct charge percent to 0% randomly.

While not charging it will either show a red battery indicator in the notification area or just an empty battery when it decides to shut down

Sometimes it will boot right up and be back up to regular charge level (of course just to shut down again within a few minutes)

Other times it will not boot up and I noticed the error message (almost like a debug prompt mistakenly left in the code) in the upper left corner "Show low low battery logo" + some strange symbol like when you get 100 1-Ups in Super Mario Brothers :). Yes the message has the word "low" twice - I guess this is lower than standard low!

Anyway, kinda bummed but since I have not seen any other report of this particular issue I'm hopeful that the replacement will not have the same problem. I'm just hoping I don't get a unit that has some of the other problems being reported so I'm crossing my fingers.

Mine started doing the same this morning :(
[Nexus 7 Q&A, Help & Troubleshooting] omnikai:
This sounds pretty similar to my problem from another thread. Every time it hits 25% while discharging it dies. Normally I'd say it's just a software calibration issue and fixable by wiping battery stats, but I've wiped several times at 100% and run down to 25% and it still dies.

Do you find that you still get a normal amount of battery life before it dies? It'd help to establish whether this is the battery misreporting, or actually not discharging properly.

* Strangely this time after my N7 had died at 25% I turned it on and it's at 0% battery. It's been charging for ~15min and it still says 0%... When you all first got the device, did you let it run to 0%, or did you charge it right away?

** And now, after almost an hour, it's at 1%. Seems to be charging, but brutally slowly (and I'm using the bundled charger, not PC USB).
[Nexus 7 Q&A, Help & Troubleshooting] dbstrat:
Yours sounds like a similar but different issue. My N7 dies regardless of how much charge it has. It can have 100% charge and within 5 minutes it will report 0% charge and die. Then when I can get it to boot again it will be back up to 99% charge again. I can't get more than 10 minutes of use before it dies regardless of how much charge it truly has.
[Nexus 7 Q&A, Help & Troubleshooting] NeoMagus:
I'm starting to have this same issue, however mine goes at about 19%. Just turns off. I have also seen the show low battery in white text thing. I have tried calibrating by fully charging then deleting batterystats.bin from data/system and letting it decharge and it still died around there, I'm recharging again to 100 to see what happens this next time I let it go... thought mine was issue free than this happens
[Nexus 7 Q&A, Help & Troubleshooting] NeoMagus:
Well in case anyone else runs into this, I have no idea what caused this or how I got out of it thinking it was dead at 20%. I tried deleting the stats, reflashed stock and then CM10 and back again, tried a different kernel, and still died at 20 and gave me the "low low battery logo".

I just took it into Gamestop where I got it and started the process for an exchange, so I have another one coming now. Go figure when I got home I plugged it back in, and now this time just like omnikai said instead of being at 20% it was at 0 when I turned it on. Been a while and now and seems to be charging normally so hopefully it will decharge fine.. either way really weird only problem I've had with mine so far

** Just wanted to edit and say its now decharging normally dont know what caused it to spazz out or fix it one of those ghost in the machine android moments

if anyone else gets this, try disconnecting the battery and then re connect and see if that fixes it. i had same type of issue on viewsonic g-tab and that was the required fix.

This is the app

You need to be rooted
[Nexus 7 Q&A, Help & Troubleshooting] Beekhouse:
Same problem here when battery reaches 24% whole tab dies...

Did someone fixed it?
[Nexus 7 Q&A, Help & Troubleshooting] najaboy:
While this reply is late to the game, it needs to be pointed out that such apps are 100% snake oil and do not calibrate the battery. They are based upon gross misinformation and any dev that tells you that clearing batterystats.bin has any effect on battery life or reported battery charge clearly doesn't know how Android works.
[Nexus 7 Q&A, Help & Troubleshooting] noisetty13:
Have you fixed this yet cos mine does the same?
[Nexus 7 Q&A, Help & Troubleshooting] AdamK123:
I had been having the same problems that everyone described: would suddenly die at 25% and wouldn't turn back on unless I gave it a charge for a bit and then held the power button down for a while.

For the last 2 weeks, I've been charging it only with the stock charger and that seems to have fixed it. Previously I would charge with any charger I had around.

Not sure if it's a permanent fix but it's working now (I've taken it down to 4% before charging it back up).
[Nexus 7 Q&A, Help & Troubleshooting] noisetty13:
I only use the stock charger on mine but after this happened so often I tried another one and battery charged OK but then kept blipping from say 50% to 54%, went bed with it at 49% and this morning dead again. Charged it again today on stock charger and waiting to see what happens.
[Nexus 7 Q&A, Help & Troubleshooting] xilefian:
Sorry all for this bump.

I just got this same issue tonight on stock, unrooted nexus 7 16gb and I only use the stock charger, I let it die through battery and then when I charged it amend turned it on, all these problems happened.

One symptom that hasn't been mentioned is that the clock is set back to January 1st 1am.

I managed to get it to start without turning off by holding the power button until the Google logo showed twice, at the moment it's on but charging.

Hope this doesn't become a problem again in the future.

I am currently having the 20% problem. Did your tablet reaminworking normally since the self correction?
[Nexus 7 Q&A, Help & Troubleshooting] ArjBasu:
A Probable solution to the nexus 7 dying at 15% + charge

I recently started having the same problem with my 2 month old rooted Nexus 7 (wifi only) . It was dying at about 19% - 23% charge . Tried doing the battery recallibration at 100% charge, even wiped the device clean and flashed the Jellybean 4.2 factory image but it didn't work.

I talked with the ASUS service center guys to get it fixed, and created a sort of guest user so that I won't have to disconnect my accounts. After that my problem seems to have been fixed. I discharged it to about 4% and then put it to charge, it's charging properly now so I am hoping the problem has been fixed.

I am not sure whether this would work for everybody, but I guess it's worth a try.

I'm running the latest full throttle cdma from. My question is is there a way to do a group sms ? I have the group in my contacts, but cannot find a way to send a text to that group. This is extremely important for my job. I've already search the forums and haven't found an answer. Any help would be greatly appreciated!

Never mind, I decided to just use go SMS. I was just trying to avoid using a third party messenger because the theme was so nice.
[HD2 General] DillonBladez:
Hey all,

Firstly, if this thread is in the wrong place, then by all means move it. There are specific threads for Android and Wp7 questions, however this does not have to do with either of them specifically.

Anyways, I'm thinking of getting the HD2; I know it's an ageing phone but it seems to do the impossible :)

My reasons are

1) I'm looking for a phone to tie me over until I can afford a more "Upgrade-y" kind of upgrade, specs wise it is a downgrade from my current phone.

2) I love tinkering with phones and using the latest builds of whatever this baby runs. Unfortunately I'm no dev but maybe I'll get to it some day. Anyways, this will be more or less a toy for me, and perhaps even an educational tool.

3) I've gone through a lot of phones and I tend to get somewhat bored with them, which is why I cycle through them pretty often. The amazing HD2 runs so many things I doubt I'm going to get bored.

Anyways, I would like some user opinions on the usability of this phone. I realize that using the latest Jelly Bean build or whatnot will probably be slow and sluggish, and that's usually fine (as long as it's not slow to the point where it's unusable) but at times I will need stable roms. I'd like to know how performance is on the most stable of roms. I don't use it for games much, only texting and light web browsing, so for these simple tasks I'd expect them to be buttery smooth, but is that how it works in reality? let me know.

Also, aside from the great things I hear about the HD2, I've also heard of a freezing issue that pretty much renders the phone unusable without a hard reboot, and I hear it is due to the CPU overheating. I'm not sure if this is such a common issue but please let me know.

Finally, how does this perform with day to day functions? Screen legibility, speaker volume, responsiveness, battery life, etc...

Thanks a ton!

-Dillon
[HD2 General] jianC:
I had no problems using the HD2 until the digitizer died on me (common issue).. Screen legibility is great on such a huge screen, speaker volume is good, responsiveness is good, and battery life is decent. I could get through an entire day with some calls, some games, some texting and still have ~40% left. The performance is great on most roms I have tried. All AOSP/CM/etc ICS, GB, and Froyo are all very smooth. Even the sense roms ported over from newer devices are butter smooth. There are so many choices, you can practically flash a new rom every week and won't be bored by the end of the year.
[HD2 General] DillonBladez:
Hey, thanks for the reply.

Do you know what the digitizer problem is caused by? Perhaps I can prevent it. But if I can't, would buying a new digitizer fix the problem?
[HD2 General] jianC:
No problem, the digitizer problem is caused by the digitizer flex ribbon physically wearing out over time. It only occurs because the "end call/power" button is directly on top of that flex ribbon.. You can avoid this by not using the power button at all and use an app that emulates that button to turn off your phone. Buying a new digitizer will fix the problem, but if you have never opened the HD2 before, best to pay a professional to do it since it is a pain in the arse to disassemble and assemble..
[HD2 General] IWR:
Been using an HD2 for a good while and basically I would have to think very caerfully before upgrading. It does everything I need and does most things very well indeed. If you can find one at a good s/h price I'd say go for it.

Advantages:

Good screen for Internet browsing,etc.

Gorilla glass so reasonably damage-resistant.

One of the best phone cameras I've used, can be tweaked even further, see hacks.

GPS and magnetic compass.

Plays music even when in standby.

NOT WM7 so you don't have to encrypt the microSD card.

Stable. Runs for weeks without crashing.

Disadvantages:

A bit large. (I keep mine in a shirt pocket, which I find works well.)

Needs charging daily if you use it a lot. (Spare batts are cheap though)

Limited RAM, therefore don't open too many apps at once.

OS WM6.5, less easy to use than Android, though plenty free apps available.

Major annoyance:

Random dialling when on phone screen, due to static or a shirtsleeve-touch. Wish I could find a way to remove that speed-dial background list which seems to be the culprit. Basically, NEVER leave the thing on the phone screen unless you are in a call.

Minor annoyance:

Badly placed volume keys. Hard to pick up without accidentally changing volume.

Not all headphones are suitable for music use. Some give very inadequate volume.
[HD2 General] DillonBladez:
Thanks for the informative response. Did you happen to have the digitizer issue that Jian had, or the overheating issue?

When you said that some headphones were unsuitable for music, was it specifically headphones with a Mic or Volume control on them? Trying to use a pair of Monster Jamz (which had volume/playback control for iPod/iPhone) didn't really give me a "full" sound without pressing on the play/pause button.

Also, all of these things were on WinMo 6.5, correct? Have you tried a WP7 or Android rom?
[HD2 General] Moschino02:
Had my phone since release date.yep your right, the phone is a Beast!

I cannot recall how many roms, builds, os's whatever you want to call em i have installed in the past year fews and everytime i love my phone even more .i think the only time i will get another phone is if the hardware specs outweigh the hd2 that it cannot cope will a new os ie window8 apparently

Listen, There are thousands of reviews on this website but dont read into it that much. Its all about trial and error and how you go about your own business - by all means read the threads too as common faults do occur- but every phone user is different and alot of factors have an impact ie have you got the right radio installed ,have you got the right SD card? Have you formatted the card properly ie task 29 before installing a new rom have you installed the right files etc all these issues people face are repairable but ultimately,so you will have a different experience than others.

The old windows6.5 rom were absolutely great and fun to customize

Android builds that i tried were up to scratch for everyday use , stability wise, battery life fantastic internt browsing email etc great no lag freezing

Windows7 some battery issues with certain roms and overheating i did come across at first , again if you experience this "trial and error" try another rom, im currently using pdamatejam now for 2months no looking back.. For everyday use, stability excellant, battery life over 24hours etc no lag freezing

Im dualbooting so chopping and changing inbetween android and windows 7 a feature many phones cannot offer.i love the hd2

Note..Newly release build/roms will be unstable when first , thats expected but overtime they become more stable as through feedback from this forum the little errors problems are reticfied -i always wait until these problems are eradicated but everyones different as lot ofpeople like to try new releases roms and leave feedback which is what the dev are asking for-

Another note the SD card ..this is a MASSIVE factor imho which causes many people problems ie boot loops freezing crashing.... I have been through 5different sd card from the start of the hd2 when you stop having problems you know you got the right one, but stay away from fakes Period.

Good luck
[HD2 General] DillonBladez:
Thanks a ton guys :)

I've another question; Should I get the TMOUS phone for it's bigger ROM capacity? If so, how can I even tell if it has more ROM than the regular? All T-Mobile phones are like that?
[HD2 General] samsamuel:
Yes all tmous have 1gb internal rom. You can tell a tmous by the red+green send+end keys, and it says T-Mobile beneath the ear piece.(and its fractionally longer) They're slightly easier to brick than regular hd2, but only in one particular way (wrong radio) so as long as you know the danger it needn't be a worry.

As for jellybean, in the days since your first post there are now several jb roms that are shaping up to be as good as any previous versions. I'm running jb with my processor UNDER clocked, and barely a hint of lag anywhere.
[HD2 General] DillonBladez:
Thanks for the insight!

This phone really seems to live up to it's name.

What do you guys think of WP8 on the device? I think I read somewhere that it's using a different kernel or something from WP7, and that it's a pain in the ass to get it to work with new hardware that it wasn't meant for.
[HD2 General] immanuel20341:
i got the hd2 when it came out and i'm still using it today. It's just that good. ;)
[HD2 General] DillonBladez:
Also, I forgot to ask; Is there a notification LED on the HD2? It seems so small that it's not really mentioned anywhere, for any phone, but it's quite useful to me.
[HD2 General] jianC:
Yes there is. It is on the left side of the speaker and it only has two colors: amber/orange and green.
[HD2 General] Mister B:
I personally think the development effort would best be utilised on last of WP7 to make functionality superb & a few innovations to make W8 users envious.

Chasing latest OS's does not always result in real practical usable device.
[HD2 General] zipperant:
friend its perefect the phone big variety of roms!
[HD2 General] DillonBladez:
Sorry for not replying for a while,

Does the hd2 encounter some of the force close mishaps caused by lack of ram? Its only got 512mb, and I find my current phone with the same amount of ram to be doing this often. Would the wp7 Roms perform better in the stability aspects?

Thanks a ton,

Dillon.
[HD2 General] anonymous-x:
I still have an HD2 sitting w/a couple extra cells I'm not using, it's still brand new, it was never used just the box opened. I'm kinda slow answering emails but give me a shout.
[HD2 General] htccraze:
I'm running the latest Jelly Bean build without overclocking and I think it runs rather smooth. At times it can pause for just a slit second but this isn't very often.

If your looking for a great phone that can do just about anything (but Sense 4) then this is the phone. Because this phone has a very high developer following it

often has new ROMs being released. This is one of the biggest reasons why I got the phone myself. I came from the HTC Touch Pro 2 so I picked this phone up

back in late 2009 early 2010. There are some great deals for the phone now that its several years old but I really feel this phone is going to last a long time to come.
[HD2 General] DillonBladez:
I'm looking to use the phone mainly for text messaging, perhaps some facebook and light gaming.

Right now I'm choosing between the HD2 and the S II.

They both seem to have a bit of developer backing (obviously the HD2 has more), but is the S II worth the extra $150ish over the HD2?
[HD2 General] htccraze:
Hmm thats hard to say. Both are great phones but personally I like HTC phones a little more. Mainly because I like HTC Sense. Samsung though is my second favorite so you really can't go wrong with either. I really like the Galaxy S II and the screen is a lot better then the HD2 as well as the camera. Some of its other specs are a little better then the HD2 but the big selling point is choice. With the HD2 if you start to get tired of Windows Mobile 6.5 (stock) you can switch to Android. Then if you ever get tired of that you can go to Windows Phone 7.5. I've bought several phones since I bought my HD2 some even that were dual core but I've always seem to end up going back to the HD2 so that should say something. I would check out some videos on youtube about both phones you're looking at to try and get an idea of what you feel you'll like best.
[HD2 General] DillonBladez:
Having owned several phones, many of which were Android, I guess I can say I'm a seasoned android user. But I was looking to get a feel for WP7 which is why the HD2 is such a compelling phone.

What do you think about the HD2 and WP8?

Also, I was googling a bit and found this thread http://xdaforums.com/showthread.php?t=734347

Have you been able to achieve these kind of results with your HD2? They look pretty damn good.
[HD2 General] :
The camera in android is not as good as the camera in WM6.5. The camera in WP7 always has too much exposure, but the quality is ok.
[HD2 General] htccraze:
I never installed Windows Phone 7 so I cant really say for sure what that would be like. Both Android and Windows Mobile though have pretty decent pictures. I found that if you are

very

still it gives excellent pictures. There are also many tweaks like the link you gave that can give you better control. The Galaxy SII I think has a 8MP camera which is a lot higher then the 5MP that comes on the HD2 but higher MP doesn't always mean better pictures. It really means how large you can increase the pictures before they get all pixelated. Because its a newer phone with more up to date specs I would have to admit the Galaxy's camera would probably be better but I still think you will be happy with the HD2 if thats what you decide on. I have found the need to take a few pictures back to back but I am still happy with its quality. There seems to be a pretty good demand for this phone though anyway so if you can get it for a good price and you dont like it, you could always sell it to get back all or most of your money. I've seen them as low as $60-$75 on ebay if you're patient enough.

Below is a picture taken with my HD2 without any mods to the camera just to give reference.
[HD2 General] Mister B:
Due to actual size of mobile lenses the pixel rating does not result in comparable quality improvement.

An old n95 with 5MP CZ lens & good camera software still outclasses some of the new big MP rated cameras in real world use due to fact lens is not large enough to benefit from high MP rating & software optimization is poor due to constant change ...
[HD2 General] DillonBladez:
Thanks for the responses. I think that I should be fine with the camera should I choose to buy the HD2.

However, the issue of proper multi touch just occurred to me. Back when I had a Desire and an X10, they both had some crippled form of multi touch that they called dual touch. It was horrendous and made typing a huge pain. I've looked on YouTube for some demos of multi touch with a multi touch visualizer, but to no avail. Could one of you confirm how many touch points the HD2 supports? I

Thanks,
[HD2 General] :
The HD2 only has two points (what you would call dual touch?). The multitouch is good enough for fast typing, in my opinion. However, the multitouch becomes jumpy if you play games that require two fingers on the screen for an extended amount of time (Ex. Counterstrike Portable), but for normal use, it is fine.
