My HD2 recently froze, so i decided to pull out the battery, and now it wont turn back on
This is after i upgraded to Android 2.3.5 Gingerbread
How can i fix this?
More info would be really helpful. when did it freeze, during boot, after boot..did it ever boot up correctly and get pass the setup? are you using clk or magldr? can you link to which gingerbread ROM you used? sorry for all the questions but without some more accurate info we would only be taking an educated guess.
So my guess would be that it might just be coininsidense it froze and really the battery is just dead. Magldr does not charge when the phone is turned off so try and get a spare battery if you can to test it out. You might have some luck going into T-mobile and asking them about it only because they might be able to grab a battery out the back to test it for you. If your not using magldr other issues could be a bad download or you flashed the wrong ROM.
I use magldr and i had this problem once, infact it took me several days to get it up and running again. If you do find out its this which hopefully its all it is you can get a spare off ebay rather cheap. I bought three spare batteries plus a wall charger for them for around $10 or so...maybe $15.
Sounds like bent battery pins, which can happen when doing battery pulls.
Take out your battery again and look at the 3 pins that stick out and make sure none are bent and all connect to the battery.
Try this... Pull the battery, plug the phone into the charger, then while plugged in, insert the batter back into the phone.
The same thing just happened to my HD2. It froze so I pulled the battery out and now it wont turn on. The only difference with mine is that I was running stock software. I had not done any tinkering with it at all such as flashing ROMs to it and whatnot. Is it completely dead or could it just be a battery issue?

Battery might be fubar, I'd try another one.
To me it sounds like the battery pins if it wasn't for he said it froze, there is no description of when it froze but that it happened after he flashed a new ROM. If it was working fine for several hours and he hadn't pulled the battery out in that time then I would think its something else since it was working at one point. With out a little more info though we are just taking an educated guess...one of many things that could have happened.

It froze when i was just going through my messages, i am using Magldr,. and the rom is Cyanogen MOD 7 Gingerbread 2.3.5, (TyphooN_CM7_v3.5.8-MAGLDR)
And yes i do have a spare battery, ive tried using new battery, but same problem applies. and the pins are all aligned

I am running DC v1.0 and i feel like ever since installing this ROM
after being on Fresh 1.1, my batter takes forever to charge via the wall
outlet (AC power). I followed all of the steps on xda as far as properly getting damage's rom to install on my phone. Running 1.6.2 recovery, and i did not upgrade my radio but that really shouldnt have any effect on how long it now takes to charge my phone. I have yet to monitor how long it would take using USB cable. Anyone else experiencing this? When i was running 1.5 while rooted, the phone would charge in no time (could go from 25% to full in about 1.5 hrs). Now it seems that an hour charging will only net me another 15% or so in battery life. Any suggestions on something i can tweak/fix or even monitor why this is happening?

I'm also running DC v1.0 and from what I can tell, if I plug into a USB port and am actually using the phone, it pretty much only "keeps up". Meaning that the battery doesn't go down, but it doesn't seem to be charging significantly either.
Haven't noticed any difference plugged into the wall. I can go from dead to fully charged in a couple hours (haven't timed it, but I'd guess about 2 1/2).
Same here, really annoying. I've been charging the thing all day...
:/
Try this. It allows the phone to sleep properly, and also helps charge time.
this is one of those off the wall things that made me flash back to fresh 1.1...lol there were to many little things that would work. but then wouldnt,, and im sure its a combo of things etc.. but i got tired lol and went back..

Ok, my battery(atleast I believe it's my battery) is having a serious issue, so hopefully someone will be able to help me out on this one. After flashing multiple roms and such over time now, this has never happened till now, basically whats going on is my phone will be completely charged, then ill unplug it and mess around with it for a short time then say the battery percentage is at 75% well randomly the phone will just completely shut off. When turning it back on the battery will be completely dead, or on occasion it will either be slightly the same percentage or lower, but most of the time completely dead. Ive been running the same old stock evo battery since the day the evo came out and im currently running Gruesomwolf's shooter e3d rom which ironically this all started happening the first time I flashed it. So hopefully someone can help out with this, been thinking the battery is just done for, but im not sure. So I figured i'd ask for some help and opinions on what to do haha
Sounds like the battery is done to me.

since no one's said it, I think your battery is pining for the fjords.
Might want to clear battery stats and charge to full once while the phone is turned off, but I really think daisies are being pushed up...
Check and clean the contacts on both the battery and on the phone itself, being careful not to short the battery while cleaning it. Then, reinstall the battery and make sure theres not too much or any play where contact may be lost. If you do that and still have a problem, its definitely new battery time.

your battery might be dead but you should either try 1 of 3 things first:
1 - you can calibrate your battery
2 - Flash a new Kernel
3 - Flash a new Rom
you may find aosp roms/kernels in the link in my sig, if you are interested. hope i helped ^_^

Sounds like its toast to me as well. But you can try calibrating like others have mentioned just for sh*ts and giggles. It may or may not help.
Unplugging your battery and dropping a ton of percentage...that's normal with most evos...lack of an SBC kernel

If u clean the contacts use a qtip and 91% rubbing alcohol. Let it sit for 30 mins so the alcohol can completely evaporate. Then charge til green light with phone off, boot into recovery wipe battery stats, and cache and dalvik while ur there, reboot to phone run it completely dead recharge to green while phone is still off. Use like normal afterwards if battery is still acting up time to euthanize it and get a replacement
Edit: by 91% alcohol I mean the bottle says 91% on it not like 91% alcohol mixed with 9% water its the purest alcohol u can buy at the store

hello guys, i had recently bought a nexus 7 16gb about a month ago, and while i was gone for the weekend, my little sister was using it. When i returned, she said it had completely died and she had been charging all night but was still at 0%. I've tried the common fixes that everyone has tried, but for some reason my battery says it will not charge, but yet i left it on the charged for over 6 hours and its still at 0%. When i got to Settings > Battery > it has been unplugged for well over 18 hours. is there any fixes out there or any way to reset the battery stats? i'm on 4.1.2/ stock non-rooted. can post screenshots if needed. i dont want to keep charging and risk overcharging my battery or anything like that. It doesnt get hot, make any weird noises or anything. Thank you in advance!
I think you have loose battery connector.

Sounds like a loose connection in the battery.
If you dare, pop the back open and then check the flex cable.
When she said that 'it has completely died', did she mean it just randomly went off when she was using it and the battery level wasn't empty, or did she mean that she had got the 4% warning and kept using it until it died? This is important.
If it was the former, then yes, the battery connector may have come out. If it was the latter, it's very unlikely its anything to do with the connector. I'm sure I've seen something before about a problem when someone has used it until it has completely ran out of charge until it switched off.

Ask her by the scruff of neck, did you drop my n7. If she say's yes, either send in for repair using your warranty or pop off the back. Since it is recently bought - probably better to use the warranty...
thank you guys for the replys, i dont think its a loose battery connector, i popped the back off and everything seems to be okay, i let it charge for like 8 hours and then have been playing with it for about 9 hours now, its what it says in the settings, but it still says the battery has 0%, but its functioning just fine..? idk, its pretty weird but its running completely normal..

thank you xateeq, Wilks3y, and knuckles, it was just a loose cable. Also, when i had the back off, i noticed there was 4 soft buttons but only three that are pressable (power, vol up and vol down). did they have plans to make a camera shortcut perhaps? also, i realized there were two screws that are missing out of the holes. is that a normal mishap on their behalf? thanks for the answers guys, just a little curious.

Yes, that's normal, because they caused the screen lift in the first parties of N7, and without them the issue seems to have been resolved

Yeah when you had the back off you would have seen the empty square bit where there was originally going to be a rear camera, before Google told asus to take it out of the design. Sure someone from the modding community will be working on that.... In fact i saw a thread where they found out what camera was going to be in there, and they were in the process of trying to get it in and working...

2 days ago my phone (for the first time) just shut off and wouldn't turn back on even if I held the power button. It turned back on after plugging it into an outlet and holding the power button. The same thing happened today.
I'm using the stock battery (I just bought the Anker battery because I figure it's the battery causing issues) and I'm on Scott's CleanROM. I've had the phone since July (brand new) and haven't had any problems since.
How long have you been on this rom/release version? Got a new kernel or try any new kernel settings? Maybe try using the new battery for a few days to see if that's the problem?

I think I just got unlucky with a defective OEM battery. The new battery comes in tomorrow so I'll stick it in there and let you guys know what happens.
Ironically, my phone has this issue when the battery discharges to around ~40%. It's fully charged right now so I want to test that theory as well.

Well whatever works for ya. I'd hate to be that one case of a bad battery. Let us know.
So that didn't fix anything since I got the same issue again today with the Anker battery. I have a feeling it's the "hover your hand over the phone" gesture since this happens when the phone is in my pocket pressing against my wallet.
I have an L01F, a Japanese G2. The ROM right now is CloudyG2 3.3, with the stock Cloudy kernel. My problem is that the phone seemingly doesn't charge to 100%; it usually stops at 93-98%, but unplugging it and a simple reboot immediately changes the reading to 100%. I dug around, and whenever the phone stops charging at a level below 100%, the voltage reading is at ~4200mV, which is supposed to be 100%. I've done battery calibration numerous times already, and nothing seems to work. The problem first started showing when I installed KK Dorimanx kernel when I was still using CloudyG2 2.2 (KK). I've moved on to CloudyG2 3.3 (LP) with proper wipes, but to no avail. Anyone have any idea what's going on?
EDIT: the battery voltage hovers at around 4330mV when it stops charging below 100%
Seems like battery controller problem?..
Would that mean I have to replace the battery to fix this?
I don't think that you should do that.
For example my Mac shows 99% max, and wife's older one shows 93% max.
Just an update:
I recently found out that, using the hidden menu *#*#4636#*#*, the battery hovers at around 4330mV when it stops charging below 100% (in the past it would stop charging at around 4200mV). I think that this is detrimental for the battery's longevity, and I need to fix this asap. I've tried calibrating the battery again using the appropriate steps, still no luck. Anyone have any idea? Could this be a ROM bug? Kernel?

The battery is around 1.5 years old. And I have done complete discharge and (undisturbed) charge cycles multiple times now. It only gets straight to 100% if I leave it turned off while charging. Else, I would need a reboot to change the reading to 100% after it stops charging.

At that rate I'd look into a replacement battery. Litium cells build internal resistance over discharge cycles.and Given uve done full discharge/charge cycles only getting a full charge when off is a good sign.
If I remember right u said you have a LG G2. It does not have a replaceable battery it is very easy to swap. I can try and do a basic teardown video of a G2 tomorrow at work if you would like.

Not a problem man. I'll dig through the boxes at work tomorrow to build a G2 and tear it down. A new battery should be pretty easy to find on eBay, swappa, or some of the various parts dealers on line for pretty cheap. That used to be one of the biggest problems with g2's aside from broken lcd's

Try draining the phone till it shuts itself off, then charge it to 100% while the phone is still off.
Boot it back up with the power cord still attached.
It should be back to 100%.
If you have the time, a normal discharge refresh is 100%>0%>100%>0%>100%. So 3 cycles.(I do this with my 3000mA LiPo batteries at 1amp and it takes like 15 hours.)
If that doesn't help, you could try to check internal resistance, if it's over 500mili-ohms, it's a bad battery.

Thanks for the tips! And nope, I haven't been able to perform a normal discharge refresh. Unfortunately, I don't have that much time to spare away from my phone. But will definitely try this if I do find the time (before getting a replacement battery, that is).
Are you getting the same results with other roms too? Try Dirty Deeds rom, if you haven't tried it yet.

Unfortunately, it's the same with other compatible roms. AFAIK only a few roms are compatible with L01F (Japanese G2), and Dirty Deeds isn't one of them.
What I haven't tried is flashing the kdz, since I don't have the time to do that, plus I don't like JB (though the stock JB gave me the best battery life by far). Thinking back, this problem might have started when I played around with the charging speed options in the KK Dorimanx kernel back when I was in CloudyG2 2.2.

Sorry it took so long to get this made. finally got a g2 to tear apart. all thats needed is a gituar pick/nails/etc, p00 Philips screwdriver
turn sound off, theres no important audio.
1 remove sim tray
2 pry up the corner and use pick to remove back cover
3 Unscrew top and bottom plastic pieces, remembering where the black screw goes
4 remove associated ribbions and peel buttons back.
5 Pry battery out, Use a little caution here since it is a lithium battery, and you are using the back of the frame and lcd as leverage.
the frame is pretty sturdy. and the battery is taped in pretty good. a little 99% alcohol can help loosen it when the corner is peeled up,
Reinstall is opposite
