So this question stems from having a cm9 touchpad. If you fullly discharge the battery and plug in the touchpad, it will boot up after the battery gets like 5%.
Is this specific to the touchpad or is there a way to get the iconia to do it as well?
Reason I am asking is that I plan to install this in my dashboard and it would suck if I am away a few days and the thing fully discharges and I have to pull out the dash to just get at the power button.
Thanks
If you install it in the dash, you may not get a good gps signal.
But to answer upper your question, I don't think out will auto boot. You may need to tap into the power switch and install a dash switch.

Um is your phone running the stock rom or a tweaked rom?
are you using your phone with its intended carrier. IE: does your Rom match your carrier? If not the proxies are probably set wrong.
I am using a straight out of the box sprint phone on sprints network. I am now seeing that sometimes stuff updates and sometimes it doesn't. Sometimes it looks like it goes back to a previous state after having updated.
Also... bluetooth power usage. Can I just assume that battery life will be crappy if I leave bluetooth on all the time?
I drive around now with a power inverter under my passenger seat in the car because I think the wall charger charges the phone faster than the cig adapter and because i can snatch the adapter out of the car and plug it into the wall where ever I happen to be.
Will the 2150mAh battery make a significant difference usage of the phone with the bluetooth on? There are times that I can take a fully charged phone off the charger at 8am and talk some on my hr commute to work and have an essentially shot battery by 10:30-11 am. I work in Washington DC which has a mandatory bluetooth use law. It would seem that I could actually kill the phone battery on one hr or so long phone call if the bluetooth didn't die first. I have a callpod dragon blue tooth.
I'd rather drag a charger around than have a huge battery on the phone.
Has anyone used the TP2 with wifi router? When I had my TP wifi router would drain the battery faster than i could charge it even with the wall charger. Can I change this by using a bigger battery or by using a high powered but still safe battery charger?
Hi guys, this morning my desire was vibrating like mad, it was plugged in charge overnight, the screen was off and it was constantly vibrating, so I took the battery out. When putting it back in the phone wouldn't turn on and when holding the power button constantly down it would vibrate again like mad :-$ any ideas?? Thanks
How often does it vibrate? Seven times? If yes, then your phone might be bricked.

Its a constant vibrate, I changed my battery and the phone switches on and works fine
Its just my other battery. Could this mean the battery got overcharged and is now damaged? Any tips?

Such information would have fitted perfectly in the initial post as well.. From OP there were no indication that your phone turned on at all.
But yes seems likely, and if it doesn't work then throw it out.
Funny enough i put that old battrery back in, and after a few presses of the power button, it switched on, i put it on charge, and currently it was showing 0% but charging, and its charging very slow now :-s could this mean something else? because the battery was on charge overnight. Would a battery calbiration sort this problem?
p.s the battery is only 2 months old, being a genuine htc innovation one, it shouldnt go that quick i assume.

Probably.. It most likely won't ruin you phone, so keep using it, if it still works.
ok that battery is not charging at all, stays at 0% while plugged in, and if i switch the phone off and let it charge, then after a few mins the fone starts constantly vibrating like mad, i went into recovery - advanced - wipe battery stats as well but its still doing it, should i assume it is the battery which is completely gone now?
With my 2nd battery its working fine as normal.
It must be the battery, time for the bin I think...

So today my battery was draining pretty quickly and I just let my phone die. And right now it's charging, but I can't turn it on. The screen has a symbol of the battery icon and a warning sign. Is this a bad sign? Anyone ever get this?
Pull your battery and leave it out for about 10 minutes while you make coffee. Put it back in and it should start just fine assuming you have charged it. Also I recommend charging directly on wall charger, not USB plugged into computer.
If that doesn't work, hold the volume button up while holding the power button down. Just keep holding them. This will eventually open your recovery. Then click select "reboot phone" and hit power.

I've had this happen to me about a week ago, I wake up to find my phone dead and not charging. Luckily I have a spare (from my old one that was replaced) so I've been using it.
I've left it out for a while, but no luck. Tried booting from recovery and stuff, but it just turns on, doesn't charge then shuts off. I haven't done a whole lot to fix it, been busy but I think if I try again and let it sit on the charger for a bit, it may just be fine.
Edit: Went ahead and swapped the batteries then set in on the charger (wall) . Not showing the triangle, hopefully it charges just fine.
That shows when the battery is fully drained. The phone needs to charge for a bit to have enough power to turn on. It's the E4GT version of the iphone/ipad/ipod touch image when the battery is fully dead and just a little lightning bolt is showing under the battery when you charge it.

Left is the fully dead screen. (just like the battery with warning sign on E4GT)
Right is normal charging screen. (like normal batter with dots under it on E4GT)

Yeah I thought so. The weird thing is, I've been draining my battery quite often, since I've been doing ROM Beta testing so I wanted to get real battery percentages and such. One time, I even turned on the phone quite a few times after it would shut off just to make sure it was completely dead, and once it was, it never showed the triangle. This happened randomly during the night while I was asleep, with fully or nearly full battery life.
I'm sure it's no biggie, which is why I wasn't worried. Well I had it charge up a bit, and booting it up, everything seems fine. Either way I have a spare battery in case this one goes bad.
Charged it for around 5 hours and still getting this error. I'm just gonna leave the battery out for like 30 minutes and start charging it again. Just to make sure, this is a battery problem and not a phone problem, right? I would hate to be bricking my phone again xD
Hello everyone,
I have my old willy here on a drawer and i just remembered i could use it as a GPS tracker for my car in case some day (hopefully not) someone will try to take it away from me.
The plan is just to leave it hidden somewhere inside the vehicle and have it always on probably with a power bank connected too for when the battery drains. The powerbank itself is connected to the car power to start charging when the car is on.
There are tons of different apps to handle this so the problem isn't that. The problem is the "always on"... There are some periods when i only use my car once a week or less and even then it is not enough to charge the power bank completly. So there are times when the phone would be with no battery left and shuts down.
All i want is a way for it to auto power on when some charge is initiated (ie. the car is started and the battery starts charging). Simply put, is there any way for the phone to turn on when it is connected to a charger?
I have found some people that could acheive this by modifing the lpm file in /system/bin but that file is not present in my CM7 wildfire. This file controls the launch of that ugly battery screen that shows when we charge a phone if it is powered off, the replace that screen launch by a boot command. Where in our wildfire is that file present?
If it is not possible, how much time would you gess the battery will last beeing with the screen off? What cappacity of powerbank would be needed to last for, say, 2 weeks?
Thank you very much

Firstly, this is a pretty cool idea =)
Secondly you would need to work out how slowly the battery discharges. So say on idle with no screen time you get 2 days, with a stock the battery of say 1300mAh. In order to run two weeks you would need 7 full charges. So 7x1300mAh should be a 9100mAh battery.
Now as far as your power on is concerned its the recovery on htc devices that deal with charging while off and low power management as far as i know. So you could try look to the kernel or the clockworkmod source code for a way to power on or you could try make a device that activated the power button once the car engine was turned on, depressing it for say a full minute then releasing. When your android is already powered on the screen turning on will be the only side effect.
I will keep thinking =)

You kinda answered my question. If that math is right, if I connect the phone to a 20000mAh powerbank I have a month of life to give it. I can live with that. Not the "cleanest" solution but not bad. I use the car at least once a week so....
If I hardwire it to the car battery which is 60000mAh it would last even longer
Some device to push the button would be too unpractical, it has to be a software solution like the one I talked about. People have done this in all of the samsungs and also I have seen in a Sony x10 mini, all done modifying the bootloader. Unfortunately, my knowledge about how to fiddle in bootloaders, kernels or source codes is laughable at best, so I need some kind of walk-through...
Imagine beeing able to hide it inside the sun visor with a little peek hole... Instant mugshot!

Hi. I bought the Pixel C and the official keyboard used from 2 different people but both devices are practically new.
I have tried this twice now. When I stick the tablet and it's keyboard together in the evening, the keyboard charging features drains the tablet's battery flat. Anyone else experienced this? Any fix other than not putting them together? (What they're meant for!)
I tried this on mine last night and over a period of approx 12 hours the drain on the tablet's battery was just 5% from 98 down to 93 so I would think there's more going on with your tablet than just charging the keyboard?

I occasionally notice that when I put the keyboard and pixel together, I will accidentally turn the screen on, or maybe its the keyboard that does that. Anyway, I've had it happen where the screen remains on. Maybe it's caused by putting the keyboard on backwards? Anyway, the result is that the screen stays on and drains the battery. I would check that. I think maybe the magnets, if they are misaligned, keep the screen on (like it always detects that one of those "magic" covers is on).
Other than that, I haven't noticed any drain from my keyboard. In fact, since updating to Oreo, my overnight battery drain negligible (like 1%).
OK but it happens when the tablet is switched off. How can a tablet that's turned off have any apps draining the battery? The screen and keyboard are put together the right way and there is no misalignment. Anyone else having this issue or is it just me?? It's quite bad, I might have to get rid of the keyboard but I need it.

Do you mean off as in "screen off" (brief touch of the power button) or off as in "power off" (from a long press of the power button)?

Had a conversation with Google support about this issue yesterday; as much to satisfy my own curiosity as anything else. Apparently, the drain on the tablet is the same, when charging the keyboard, whether the tablet is fully powered down or just screen off. The electronics is such that once the keyboard has completed a full charge, it drains no further power from the tablet's battery. However, when I asked the question "what if the battery is sub-optimal or worn out?", the answer was "we have no way of knowing what the drain on the tablet's battery would be under those circumstances..." (!)

I meant actually powered off. I delayed replying because I wanted to test it further. For several days the battery charge was fine in the morning whether the tablet was powered off or not. This morning though I found it completely flat again. I had left it switched on, with battery saver on and stuck to the keyboard. The tablet was hot also... Very annoying defect as this will prematurely kill the battery which, I believe, is not replaceable.

Having the same issue with the keyboard. The keyboard is also charging when it's behind the tablet, and the battery on the tablet is drained out overnight. It also gets hot from the charging. No fix unfortunately, it seems.
