[Q] Charging Battery - HD2 Windows Phone 7 Q&A, Help & Troubleshooting an

For me there is a very strange Battery charging on my HD2 with WP7. I'm normally charging and after a hour the green LED is shown. But When i unplug the cable und plug it in again, it is charging again ^^
Is it a System Bug? I don't know when my Battery is really full, cause it can't be, that after 30 minutes the battery is draining so much, that i can see a not full batteryicon. Ah and after i make a reset, so reboot my Phone, Battery is again Full.
Maybe it's like on Apple where it is sometimes under 15 % then again on 30% then on 45%, after some minutes again under 20% :-D

Xperia wont charge to 100% - gets stuck at 90 %

Xperia wont charge to 100% - gets stuck at 90 %
any ideas whats going on?
its been charging all night at 90% :S
are you charging via usb to pc, or usb to floor charger?
i hope battery not been extremely discharged before....
USB - but i've just done 2 restarts and 3 soft resets and its gone up to 100% now - really odd problem - lucjy its fixed - phew
if you can't get it to 100% charge while charging with the floor charger..
you might have already discharged it too greatly.
90% might be your new maximum, unless it's the phone's problem.
EDIT: Ah I see, that's good then! I usually charge it with the floor charger since it's faster than a pc-usb charge =]
Good news then~
If you have a laptop and you're trying to charge you're phone thru the USB port...you'll wait A LONG LONG time...
I only use the floor charger...
i think by doing a soft reset, you just recalibrated the battery settings. just a guess tho. sometimes battery charge, and indication gets out of sync and so you have to recalibrate them. as i said, dont know if this applies to the x1.
To recalibrate a battery you need to drain it to the last drop then charge it fully (i think preferably thru Wall charger) for several hours.. so the battery controller can detect which voltage range the battery is working on... normally i think when i charge thru usb it gives me power but i think it drops faster... than when on wall charger...
just don't drain it very often.. it makes your batt go bad... i read somewhere that once every three months is ok...

Software problem emptying battery?

Ok so I just charged my battery all day, it was at 100%, took it off charge.
5 minutes later I plug it in to charge while im at my desk and took the battery out for about 5 minutes - phone was still plugged in.
Put the battery in and its flat. I get a warning saying its below 5% and now I need to charge it otherwise my phone shuts down
I know full well the battery isn't dead, but the phone thinks it is
Whats the deal?

Battery will NEVER fully charge!!

I've been experiencing problems(like most) with battery life on the Epic, so I found a thread here from the EVO forums about "recalibrating" the battery. It involves steps of fully charging with it on, removing cable, powering down, plugging back in, etc...
Well I've actually come to realize that a blue LED should turn on when the battery is fully charged & the phone should stop charging(duh). Well i've tried for the last two days for the blue LED to come on after countless hours of charging, resetting the phone, etc. I've now had my phone on the charger for 8+ hours & my battery widget states 100% yet it continues to charge!
Has anyone else experienced anything like this?
No, but my wife's battery would drop immediately from 100% to 75% as soon as it was removed from the charger. This occurred no matter what charging regime I tried. I know that the battery may start to discharge after its peak charge has been obtained, and that it is possible to remove the charger and see only 90% on the battery, but 75%?
I returned that battery last night and now today I see that this battery never gets past 98%. I'll give it a day or so to see if the battery life degrades again, in which case I'll know it is the phone and not the battery.

Are you getting the blue light and what app are you using to tell what percent? There are other thread that say some of the battery apps are off a bit. What kind of battery life are you getting?
Success!
I used a few different apps to tell the battery charge so it wasn't the apps.
I found a fix that not only allows my battery to charge to 100% but also seems to give a better charge. Since doing this my battery shows 100% when fully charged, doesn't drop significantly when I unplug the phone, and so far has caused the battery to go down very slowly. In the three and a half hours since coming off charge the battery has gone down to 93%, while holding up to my wife using it for calls and ShopSavvy. I intend on doing the instructions below every few months.
In the Evo space there are two sets of directions on how to prep your batteries for a good charge. One involves plugging and unplugging your phone while at full charge, and the other involves briefly turning your phone on and off between charges. Because I'm impatient I've amalgamated the two with success.
Fully charge the battery with the phone on (several hours)
Once the charging light is blue, unplug the charger
Turn the phone off, then plug the charger back in, for 30-60 minutes
Unplug the charger, turn the phone on for two minutes, then turn it off.
Plug the charger back in for 30-60 minutes
Then repeat this cycle about ten times: unplug the phone for five seconds, then plug it back in until it says it is at 100% (about two minutes)
For the record, I think this has little to do with the battery and a lot to do with how the phone recognizes the battery as full.
I haven't had any of these problems. My battery charges %100 with blue light and it doesn't drop after I unplug it either. Guess I'm lucky

I don't run a battery app. When the blue light comes on it's done. I get about 11-12hours before I get the low battery warning.
Ha! It really worked. She's at 17% and its been 1 day and 11 hours. Not as good as my Evo.
I guess I'll re-try calibrating the battery again, first time I tried it my battery ended up at 95% instead of the regular 98%, really odd.

That seems a little crazy. All you should really need to do is drain it until it won't power on anymore (not even for a second) then charge to 100%.
Still, the epic's sensor just isn't very accurate at the top-end (most aren't), so you're gonna get some strange behavior near the 100%.
All the older WM phones were weird like that too in the 90% range; the sensor just can't detect it very accurately near full charge. The difference was that they showed battery in 10% increments, instead of 1% (unless you use a hacked driver).
too crazy for me.
I think I'm going to just buy some spare batteries for this phone. Immediate unplugging leads to 100% battery.

I have the same problem, I'm using battery life and juiceplotter and they give me the same %

Thanks for this. I was having trouble getting my device to recognize the top 3% of the battery, and one iteration of your plan above did the trick.
^After I noticed these steps in the Evo thread last week, following them did the trick for 1 iteration.
My phone rarely has stayed long @ 100% after coming off a full charge since then, though.

[Q] When I unplug my charger, battery drops to 89%

Can anyone help??
My phone works well, and I get ok battery life. However when my phone shows fully charged after overnight charging, I unplug the cable and within a minute, the battery drops to around 90%, then normally discharges throughout the day. I would try resetting battery stats, but don't really want to root the phone. Any ideas? ?
If you don't want to root, try fully discharging the battery, and then fully charge it.

[Battery] Battery doesn't charge

I'm facing problems with charging my phone for a long time. I've already tried some roms but my phone doesn't charge in any of those, staying on the same % for a long time and sometimes decreasing it. I've tried many chargers, and all of them show high numbers on Ampere App and charge normally another phones, but not mine. When sometines I can charge, the battery has a nice duration on using, but to charge it is very slow, to get out of 0% take hours, sometimes doesn't even starts to charge. Anyone knows what I should do to repair this? There is any rom that the charging is normally with no kernel changes or something?
