Hello. I upgraded from the stock 1390 to 3500 battery. Now, the phone doesn't properly read the battery juice. Does anyone know how or is willing to attempt to find out how to modify the phone to properly read the new battery?
Thank you!
Hello, I just went with my wife two hours ago and we upgraded her to the Droid 2 global and the salesman told us there wasn't an extended battery for her phone. So just out of curiosity where did you find one and does it come with a bigger battery cover? She loves the phone but I'm sure she will grow to hate the battery life of these smart phones.

I bought mine at the Verizon store, i order 6 (company phones), they had to ship them, but i got them the next day. They come with a battery cover, which you can get in the blue or white covers (you can actually get it in black also because it is the same extended battery that from the original droid and droid 2). The cover adds about 2-3mm to the phone but it still works in the car dock. It allows me to use the phone all day without plugging it in.
I'd like to back up your question as well. Online there is extended batteries but the only reason I won't get one due to the phone not reading it right.
I've heard that if you simply shut off the phone and on again It adjust but this is a workaround.

I was browsing here for a friend and stumbled upon this,
your best bet is to recalibrate the battery, pretty much let it fully charge and wipe the battery stats via clockworkmod bootloader
When I buy my extended battery I'll have to try this thanks

So I found this application for rooted users I believe. Does the same as mentioned above with recalibrating the battery but makes it a little easier. It's called battery recalibration.

Not sure if this applies to the Droid 2 Global but on the Milestone you can simply delete /data/batterystats.bin ("rm /data/batterystats.bin" without the quotes in Terminal Emulator/console/ADB).
The next time the phone's plugged in it will recreate this file, it's best to make sure the battery's fully charged up.
Look for the battery calibratio thread in the Droid/Milestone forum to find out how to fully charge the battery properly, basically just charge it to 100%, turn off the phone, plug it into the wall charger and then reinsert the battery once you see the "?" Inside the battery icon and let it sit for an other 30 mins or so until the phone is cool to the touch.

There is a new app in the market place called battery Calibration. It does the Battery.bin deletion from a easy to use user interface.
Hello xda,
Before yelling at me for posting something thats already posted I haven't seen any posts that were recently
I had an Atrix 4G when the digitizer went out I got an Atrix 2 replacement (How lucky was that) well I thought I was lucky until now. I owned my Atrix 2 for 2 months and last night I was playing a game I forget the name. I remember my phone being charged at 60% then I played for about an hour and half and all of a sudden my phone froze completely, no life at all just a lighted up screen with the game being frozen. So what I thought to do is do a battery pull. When I tried to boot it back up there is no life at all but a white light.
I read every where about these white lights ranging from your phone is toast to your battery is so low on a charge that it cant boot up the dual core screen.
Now I've tried everything so far right now I have a spliced up USB port rigged up to my battery charging from my PC. I checked the volts using a multimeter and the battery at first was 0.160 volt now it's up to 0.300 volt.
Now I am not good with volts and all but can someone tell me to keep charging til its at 3.8v (I think thats the batterys capacity) or what?
And I also let it charge all night with the light on to find it done nothing.
When the phones with no battery charging the multimeter voltage says 2.5v.
Lastly, I got a battery otw incase this one isnt good which will be here Tuesday-Wednesday.
Thanks and please come with positive news if you can =D

Honestly man, it sounds like you're on the right track, and yes to the best of my knowledge, the white light has to do with low battery.
Can you not just charge it while it's off? What ROM are you on?

Nobody is going to yell at you. You have a legitimate question. I don't have a answer for your problem because this has never happened to me. After you find a fix i ask that you post whatever you did to fix this for future reference for others and myself. If you would please.

It seems you have completely drained your battery, this thing has happened to me once. What you can do is get a battery only charger from ebay and charge your battery and you'll be ready to go. This has worked for me and hopefully will work for you as well.

Good idea, I probably will invest into one because after reading I took notice this must happen alot to people and if I get this new battery then I'd have 2 completely dead batteries. Not good at all lol
I am going to let the phone charge on a wall socket for the night. Hopefully it comes back to life.
I wasn't expecting so many replies in such a short amount of time so thanks to all of you!
I went to go watch a movie tonight and we were early and I saw an AT&T store so I went inside and borrowed their battery from the Atrix on display and it booted right up.
So this means either 2 things my battery is fried or just completely dead. I tried everything I could to get it to work from splicing wires to charging all night.
I suggest for people that have this problem to either get a wall charger as posted above by prasannapmv or get a new battery.
You can also go to an AT&T store and borrow their battery, all of this is better then paying a $50 fee for your insurance or paying $300 for a new phone.
I hope this thread has helped other people.

Thank your AT&T store again. I have two in my town, neither one of them would do that.
Nothing says fine customer service like AT&T.
Hello guys I'm I little worried. Here's the thing, I tried for some days figuring out how to root,unlock bootloader, super CID, etc.. it was with good battery life, but after I did all that, I installed the viperxl (i used it with my older HOXL) and everything ran good. What I have noticed is that my battery drain is so, I mean soooo bad..!
I tried a full wipe but I think it's still the same. My phone its brand new so there is no problem with older owners. I haven't changed the radio (maybe could be that?) I have lost more battery on standby than when using the phone and that didn't happened with my older HOXL
So could be that I messed my battery when I charged the phone with the nexus 7 charger??
Or what could be the problem?? Any suggestions will be good, thanks....

Is the N7 charger more amps than the One X charger? Some folks on here have said that the device will only pull the amps it needs, others have contradicted this. I don't know enough about the topic to comment either way. I use a Motorola charger on my One X every day, since it has a longer cord than the HTC charger and it happens to work better where I have it located on my desk.
I can honestly say I've used my nexus 7 charger a few times with no problems

Its a mental thing. I use my nexus 7 charger at home and my htc one at work and a high output Motorola in the car. My battery life has always been superb. Running latest viper with beastmode evita...
From what I know about charger outputs, it doesnt matter, it depends on the device. It can only pull in its max regardless of the charger. Higher the output in a charger should be better so your phone can pull in its max
There's also other factor that contributes to horrible battery life. Rogue apps, horrible networks that switches back and forth between lte and hspa+ and so on...
The last thing could just be a bad battery. Not common but I'm pretty sure it happens

yep the specifications of amps is the current that the charger can handle, as long as the charger of the n7 can handle the same or more current than the one xl charger it should be ok, many chargers are 1A.
For the OP , i think you should definitively try with another rom, maybe stock to make sure that the problem is not your battery?

On the one x charger says output: 1A, and in the N7 charger says output: 2A, but I only charged it like 2-3 times I guess, so I don't know why I have that poor battery life,.Maybe hardware problem? Or should I change my radio??
Also how can I know if its a hardware problem??

are you still running viperXL? maybe there are some settings that are pulling your battery life... look in viperHub and viperTweaks

Your device isn't going to take in 2A. It's only going to take in what it can. I'm not saying that by using a different charger is not going to harm your device, it's just highly unlikely it will. They only way is to flash back to stock and see if that makes a different.
Also, you mention you had another 1x, is your current one a refurb or replacement? That may have something to do with it as well
The Rom is awesome but there are times when it doesn't work for very small numbers of devices...you're just prob unlucky.

It's not a replacement, I soldy older one to a friend and bought this new one, with WiFi I have noticed that standby and normal usage I have a good battery life, the problem is when I'm on 3g/H, maybe could the radio? Because when I'm on data it drains really really fast, like 3-6% per hour on standby...

It might be your radio switching back and forth that's draining your battery.
I have 2 jobs, my first one has lte coverage but not so great in the building so it's always switching from LTE to 4g which I notice drains my battery. My 2nd job at night has great coverage in and out the warehouse. I get full bars of LTE there and my battery would drain very slowly.
In the beginning, I was worried as well because my battery drain seem like a lot so I thought something was wrong but then I checked the battery at my second job and it was great so I figured it was just the network and location.
Overall, especially compared to all the androids I ever used, the one x battery is pretty damn impressive especially for an LTE device.
I came from Verizon using the droid razr and galaxy nexus which couldn't make it past 4 hours on lte with light usage

I've experienced crapp battery life after using my HP Touchpad charger.
Also, my 2nd HOX had horrible battery life out of the box. After fully draining > charging twice my screen on time went from 2.5 hours to 4+ hours with the exact same settings and usage.
Edit: while we're talking batteries... I heard a tech from.the ATT Device Service Center tell two people not to charge their phones overnight because leaving it on the charger when it's full is bad for the battery. Those guys are so smart! They must get their info from Yahoo Answers.

The battery meter calibration gets wiped whenever you flash a custom ROM. You should do at least 2-3 power cycles before making any judgements on battery. Charge to full, but only drain to 10-20%. Draining to shutoff doesn't make it any more accurate, but has the added risk that once in a while the safety circuit will not engage properly, and you will be stuck with a battery that will not accept a charge.
Also, on any ROM but stock AT&T, you can toggle LTE off. Since you don't have LTE in your area, toggle it off (if you haven't already) in Settings>Mobile network settings>network mode.

That's the explanation I've read previously.
But if so, why did HTC used a different charger plug for the HTC Flyer tablet than all their phones? The charge port is an interesting one, in that its bigger than a MicroUSB port, but will still accept a MicroUSB charge or sync cable (the plug only takes up the bottom "half" of the port when plugged in). The pins needed for data sync are the same, and in fact you can actually plug any MicroUSB sync cable or charger into the Flyer. But you can't plug the Flyer's charger (1.62 Amp) to any HTC phone, only the Flyer (and I assume the Jetstream tablet).
Many have said that this is so people would not plug the Flyer charger to a phone, and damage the phone from the higher amps.
Seems like the difference in amps is the only reason HTC used a different charge port for the Flyer.

In my experience, an uncalibrated battery can go from 8% battery to 0% in a matter of minutes. The only way that I've corrected this is with a full discharge.

You're just calibrating the meter, not the battery. The notion of calibrating the battery is left over from 80s technology NiCad batteries.
Under the best of circumstances, the battery meter is nowhere near accurate enough to expect readings less than 8% to be accurate. If you've experienced some more "accurate" reading at this granularity, it may just be placebo or pure chance. Even if true, I'd rather have a bit of inaccuracy in the low end, rather than play with the probability of a battery that won't take a charge.
In any case, you shouldn't be running your battery down that low. We all do it once in a while, but it shouldn't be habit.

The battery usage data is wiped with each boot or charge (same as wiping battery stats). But I don't think that is the same as the calibration data.

Hi everyone,
I dont know what happened with my HTC, when I woke up this morning, the phone wont turn on at all. Even if I connect it to charger, the notification light doesnt on. I tried remove the battery and reboot, but nothing works.
My phone was rooted, S-OFFed and running [ROM]Viper 1.3.5 and still working last night, I didnt do anything to it (at least when I was sleeping).
Could anyone tell me what happened to it and how to fix it?
Thanks in advance
How long was it on the charger?
Sent from my Og Evo 4G
I put it on charger for about 30min, the light doens even go on, like, no charging at all. The phone still wont turn on
Could be the battery. I have had this very same thing happen to me with a new battery. No charging light at all, no sign of life what so ever! As soon as I poped in a new different battery, my phone sprang to life once more. It was very strange because the battery I was using had charge left last I checked and it was on the charger. When I checked the phone it had no life at all. No charging light either. If I we're you, I'd try a new fully charged battery, to see if that will solve your issue. Don't mess with the device before you try the new battery. My issue was the same as yours and a new fully charged battery solved my problem. Hopefully that's all it will take to also solve yours. It certainly can't hurt to try! It worked for me. If the new battery does not solve the issue then you have a different problem all together. But do give it a try and see what happens. Best of luck.

Hi there, you can order a good extended battery like Anker for under 20 bucks. I really hope the battery does the trick. When this happened to me, it was so strange because I was using a NEW
Battery and it had around 60% charge when I plugged it into my charger . Then when I went to check the phone after changing for about a hour it was black. I took it off charger and it had no life at all. I thought maybe the charger didn't connect properly so I plugged it back in, then I noticed I didn't have any charger light like I usually have. Phone was completely dead and it would not charge. Strange. I had another fully charged new battery I kept as a spare, when I put that battery in, the phone came back to life and the charging light worked again! I have not had ANY problems since. It's been about 5 months since that happened to me. I never used that battery again. I just threw it away. It must have been something with the battery. It would not even charge! No lights or anything! I'm really hoping this is your problem also because it's easily fixed. Please keep us updated and let us know if new fully charged battery solves your issue too. It sounds exactly like what happened to me, so I'm hopeful you can solve this with another battery. I wish you the best! Good luck!

It was the battery guys, I bring it to the HTC, and they tested it with new battery, didnt work also. So, they put in a new mobo, new battery, then it worked. They insisted to keep it a few more days to serviced it though. I forgot to tell you guys it still under warranty, sorry a lot.
P.S.: They even gave me a HTC Desire as a temp phone
I've just joined the dead battery club with my 6800 tab..
won't charge at all.even stock charger no icon nothing....
been on charge all night and have tried numerous things no response.
haven't bricked it went flashing anything just have been busy
Lately haven't used it and must have drained flat.have read before
once they get flat they won't charge as need a small amount of power
From battery to activate charging circuits.
What's the best battery to put into it? Stock one on ebay for 24 usd
Just thought I would ask but is there a bigger capacity one that would fit?
Anybody done this before just looking for ideas..
i will take the battery out and try charging it with a 3.8v mobile
Charger or camera charger by using some wires if any success will
Post up if works...thinking got to put small charge into it then can use wall
Charger.
Well ordered a new battery from eBay 28 bucks delivered...
Just decided to open it up and play with it tonight and got it charging now with the old battery.will let it charge for ages before turn on.new battery still in mail.
Got it working by unplugging the battery for a while and reconnecting to wall charger.note before doing this it would not charge no matter what I used..eg 2 amps etc
Not sure why it works but read it somewhere and worked for me too.
Tab seems to work sometimes and charges ok with old battery then later i turn it on and nothing..
wont wake up even with wall charger plugged in.never had problems with deep sleep before,
maybe a couple of roms ages ago but the one im currently using hasnt done it before and been
using it for ages.im guessing its the battery playing up.anyway got my new one in mail today
and then tab wouldnt start again and i know its not that flat.I decided to change the battery and are
charging now will leave it on charge for ages till full before turning it on.
Do i have to now delete the battery stats?
thanks..
My P6800 is also dead. Won't charge, whatever plug I try
Just ordered a replacement battery + tools for opening the device. Hopefully that will fix things.
I had very similar problems to MRBR7. I was about to order a new battery, but they were over $60 on ebay at the time. I ended up just buying a new tablet - a Nexus 7 2013 - rather than putting money into the old one.
However, I decided to experiment with the GT 7.7, so I took it apart, popped out the battery and hooked it up to a specialized charger than I have to remote control cars/planes/copters. The charger "conditions" LiPo batteries - discharging them and then balanced charging them back up. That worked. After the special charger did its thing I put the battery back in the GT 7.7 and it was happy.
Since then, though, I've had several mysterious and spontaneous reboots. I'm thinking of putting the stock ROM back on it to see if that will stabilize it.
Another weird issue is that the tablet doesn't seem to track how much battery power is left very well. It can drop 10-20% in a few minutes. I know it's not really dropping, but it is certainly weird. Now that the batteries are cheaper on ebay I may order one and replace it.
Edit: Update:
I did put the stock ICS back on my 7.7. It has been behaving nicely since then. No crashes. No reboots. No funny battery behavior. So I think I'll just leave it like that. Putting Nova Launcher on it meets most of my needs for customization, so I'm happy with it.
My tab is dead again. Don't know what happened. I'll try disconnecting the battery from the tab and connect it again, and then try to charge it. It won't charge now what ever charger I try.
If it doesn't work, I might go for the nexus 9

I have a new battery that I am about to put on eBay, but it probably depends on where you are located as to whether it is worth your while. I am in the UK.

I live in Norway, so that's doable. The one I ordered on eBay took around 5 weeks to arrive...
That being said, I don't know if I will invest more in this tablet if it just keeps on destroying batteries. If I get it back up and running again I might try the stock ROM to check for battery drain.

My tab is back from the dead (again). All it needed was a little bit of power-love from the original ac adapter. Still using the replacement battery.
I've flashed it with cm11 and it runs great.
