Since I have upgraded to WM6 with the official ROM release for AT&T I have been having odd battery issues.
I forgot to charge my phone last night but when I left the house this morning it showed 40%.
I stream audiobooks from my phone to my car stereo via Bluetooth and less than 10 minutes into the drive I received a low battery warning. By the time I got to work which is about a half hour drive the phone switched itself to airplane mode and then powered down. I could not get it to come back on until I plugged into my PC at work and then it booted so it had been fully shut down.
I have noticed at other times that the battery level goes from a high number to a low number VERY quickly. It also seems to charge very quickly and can go to a full charge from a USB connection in just about 2 hours.
Anyone else see this? It was a very steady reliable discharge rate under WM5. I have seen others talking about the OS potentially mis-reading the battery level but have seen nothing conclusive. I think perhaps it is just not updating the actual battery level when it should so when I see it at 40% it was really very low and just had not updated.
Anybody else???
I havent had my phone for long and flashed it immediately to Windows Mobile 6, but what I have noticed is that it charges pretty fast and I just notices just now that if I turn the phone off while still plugged in for charging but the charge indicator on the phone was green when it was on changed to orange to indicate charging when I turned the phone off. So maybe there is something at the software level affecting the charging process as turning the phone completely off allows me to charge even further than when the phone was on.
What has worked for a number of people is to let the phone get to 0% battery so it shuts the GSM off and then itself, then plug it into the mains charger overnight. This seems to have the effect of re-calibrating the battery meter. I have no idea if this actually works or if its complete coincidence but a number of people in various Schaps threads have had success with this. There is also the possibility that your battery is just screwed. Most of us I assume have devices that are a year or more old and mobile batteries dont last very long especially in power hungry devices like the Hermes.
Another battery Observation!
I have experimented with 3g off al day, and only E (Edge) was displayed on top. 12 hours, 5 phone calls equal to 36 minutes total, I had 60% left on battery. Same hours, 5 Phone calls, with 3G turned on, 42 minutes of conversation, one email sent, 5 received, battery displays 90%. I believe EDGE is what consumes power and drains the battery. leave on 3G and your battery will indeed last longer.

I have noticed at home that when I plug it in to my Linux box (no synching of course) the charge light comes on briefly then shuts off and may come back on after about 10 seconds. I suspect in my case it may be the cable going bad but it only just started since the WM6 upgrade.

After a full charge yesterday afternoon I used my phone for a bit of reading an e-book for a half hour, 40 minutes listening to audio streamed via Bluetooth yesterday afternoon and another 40 minutes on the drive to work this morning and the phone is down to 50%. Wifi is disabled and I had no phone calls in that time. The only other usage is it automatically updating calendar and contacts with my exchange server but only every 4 hours ending at 6:00pm so that is not a big drain.
I have the device set to shut off the screen after 3 mins inactivity (not just backlight) but the battery drain seems to be much faster than it was with WM5. Perhaps it will straighten itself out with a few discharges and re-charges.
I have a wierd issue on the new purchased TP2.
I am recently I owner of Tytn II, just switched over to TP2. Once I received the TP2, it came in a full battery status. Then I used it all up and then proceed to my 1st charge ( over 12 hours, with phone off)
Things happened after I woke up in the morning.
1. No lights on for charging ( I assume that's a new feature when battery is full, instead of charging when red )
2. once I turned on and shows only 45-50% of battery status.
So I used it all up again, and see if it charges on the this time.
I am just wondering if anyone have this charging issue.
Dude, you are not treating your battery correctly. The below link has some useful info. Especially the link in post 3 by Sjuust.
http://forum.xda-developers.com/showthread.php?t=524393
Btw, when it's charging, the status light will be a solid amber. When fully charged, it's a solid green. If there's no light, check your wires and stuff. Perhaps it's a bad socket.
Just doing a follow-up on the issue, the 2nd time not successful too
I tried and it worked only when I turn the device on to get a full charge.
Anyone think it's weird
Seems you mini usb does not connect propper. Try another cable, if this works you know the problem.
Or: press the male side of the mini usb each direction until you see a light burning. If this happens the usb opening in the phone is broken and you should get it fixed.
If this all does not work, still get it fixed. It's probably not the battery, but the usb opening in your phone.

that is very unusual as when phone is fully charged it stays on constant green light(led). at no time should it go off. unfortunately your battery may just need a few more normal charging cycles to achieve its full potential. if the led light goes off that is another issue! have you added any battery customizations?
Same problem here
I have - more or less - the same issue as D810Noob. My TP2 came fully charged out of the box. First time I charged it, the amber light was on during charging. Next morning no light was shown. I am not sure, but as I recall it, the battery was 100% charged. In the recent days, after one night charging (phone switched off) the green light is being shown but battery meter shows 89% (yesterday) or 91% (this morning). I have the 1% increment battery driver installed with the greenbatteryfix-icon installed.
This morning, after having switched on the phone and after having been confronted with 91% charge status, I reconnected the phone to the charger until it reached 100% (left the phone on during charging). With only two calls of two minutes in total and gprs (no hsdpa) running for two mail accounts, battery status dropped two 80% in 5:30 hrs. Never had such a drain with my TYTN2 that had (more or less) the same configuration.
It may very well be that my battery is not (yet) calibrated correctly, albeit that I fully discharged it last night. I will redo this a couple of times before returning to the shop, but this needs to be improved otherwise I will go back to my TYTN2.

Still having this issue. I have drained my phone completely yesterday evening until it switched off itself. Ten restarted until it switched off again. Then had it charge for forteen hours (phone switched off). When I switched on the phone this morning, battery meter showed 96%. A bit more than an hour later it shows 80%. Had no phone calls, only receipt of six emails and half an hour drive in my car with BT connection. BT is on continiously, BTW.
This does not look good, does it? Anyone who can shine a light on this?
Cheers, Dela
PS: the charging light was green when I took it off the charger this morning, whilst the battery meter showing the 96% charge status right after the startup.
Is anyone else having a problem with the touch pro 2 not charging fully when it is off. I have the Tilt2 and have tried many different ROMs. For whatever reason if i charge the phone while it is off, it only charges to around 96% or less. I do have the 1% battery driver installed and i can not figure out for the life of me why it will not fully charge. If i leave the phone on, it charges to 100% but at some point i get a message telling me it disconnected from the connection. Can anyone help. Thanx
Same issue :-(
me too. Same problem
There's been several threads on this. The general consensus is the battery stops charging when it reaches 100%, and then begins to discharge. I've noticed the same behavior but haven't found a fix.
Very odd
The weird thing is that I have charged my phone while it is off and one morning I wake up and turn it on and it is at 91% then the next morning it will be at 100% then the next morning itll be 86%. I usually turn it off around the same time and turn it on around the same time. I cant see it starting to discharge if there is only an hour possible time difference. REALLY annoying lol
Icon issue with charging and Battery level
I have an odd issue. I am running the stock ATT rom until I can get the stupid phone to take the HardSPL (different issue being worked on).
The icon at the top shows the battery at full capacitiy all the time. I have Phone alarm on and it has a battery indicator that shows it as low as 20% while battery icon is still 4 bars full. Also there are times when I remove it from the usb and the charging icon stays on instead of showing the battery icon. If I soft reset then it seems to go to normal and the charging icon is replaced by battery which seems to always show full.
I've seen a few post regarding the 4.3V at 100% thing, but they're too old and haven't really given me much information.
My main issue is that I'm experiencing unusually rapid battery drops after my phone reaches 12% charge, it'd drop to 0% in just a few seconds. I downloaded a few battery calibration apps thinking that it might be a calibration issue. In that process, I noticed that the voltage read by these apps (and even in the *#*#4636#*#* menu) when fully charge is 4,38 volts. It was my understanding that Li-Po batteries should be fully charged at 4.2 volts and that charging past that point is harmful for the battery.
I also noticed that if at this point (charged at 4.38 volts - 100%) I unplugg the charger, the battery indicator would show 100% for a while, until the voltage drops below 4.2V, at that point the porcentage would change to 99%, so it seems that the device is set recognize 4,2V as fully charge, but it continues charging after that point. Also, the green light turns on at 90%, is this normal?
I tried calibrating using this app but with no results. I'm trying the manual calibration now. What is going on here? Could this be a clibration issue or do I have a faulty battery?
I think it is not normal. My P6 drops even a little bit slower from 10%. current my P6 is on 6% and 3,627V. (Edit: Turn off: 3,55V / After charge 100%: 4,32V)
Next time i will charge, then i post the Voltage at 100% for you.
To calibrate the accu you don't need any app. Use P6 until it is automatic power off. Now turn it on so often until it will not start anymore, and only show a red accu on screen. Now charge to 100%, turn on, unplug charger. Now your accu is calibrated.

Thanks, heross. So apparently the >4.2V @ 100% is not so unusual. Does your phone remain at 100% for a relatively long time and drops to 99 after the voltage is below 4.2V? Mine does that, and it also turns the led green when it reaches 90%.
I'm sure the dropping from 12% o 0% in seconds cannot be normal, but I'm wondering if the above is a symptom that something is wrong or
if it's normal.
EDIT: Ok, the phone just turned off by itself, the quick drop hapenned as usual (12% to 0% in less than a minute) and the voltage fluctuated between 3,1 and 3,3 volts in the process, maybe even less than 3.1 V, but I'm not sure. I took a series of screen shots 2 seconds apart, I'll post them when I turn the phone on again, I'll let it charge as you suggested.
Yes LED green at 90% is normal. My P6 drops to 99% after 1-2minutes screen on or after a boot without charger.
12% to 0% in seconds is definitely not normal. Normal it goes down very slowly to 3% then it comes a Info and after 30sec it power off.

Finished charging.
I've turned the phone on and it has been sitting at 100% for about 25 minutes at 4,348V with the screen on. (I even played a video with full brightess). After that it droped to 99% and 4,079V[/B]. That can't be normal.
I saw that the P6 battery is rated 4,35 volts, so i'm not too worried anymore abut that voltage and everyone else seems to have the same values, but this quick drop with 12% and the fact that it stays for so long at 100% does worries me.
The screenshots were taken 2 or 3 seconds apart. It doesn't give me a low battery warning at 15% like most phones, but at 8%
I'm still having this extremely annoying problem. The goddamn battery goes from 12-13% to 0% in a blink of an eye. I just plugged the charger at 8% and it show 0% right after and started charging from there. Voltages are strange too, it shows ~3,6 volts when it started dropping quickly. It has charged ~20% in less than ten minutes. Look at this behavior: sudden voltage drops, never went below 3,3V and dies at 3,6V (almost nominal voltage)
I've tried calibrating several with several methods a few times, I'd prefer to stop doing that since I know it stresses the battery.
Has anyone had this issue? Can someone please shed some light on WTH is wrong with this troublesome phone?
Saw this post now. I have the same problem but it is from 9% to 0% . I don't think it is the battery, i think it is how android reads your battery info. I managed to calibrate mine by charging it when off from 0% to 100%-didn't last for long, the problem appeared once again.
It stays to much at 100% after charging, so we have the same battery life. Might be the kernel, don't know. I home when emui 3.0 is relased comes with a new kernel as well.

I also managed to fix it once, I don't remember exactly what I did (I've tried so many things) but it didn't last long either, it discharged normally one time, but the next time dropped from 12% to 0% again in seconds. When will EMUI 3.0 be released?
They said emui 3.0 will be released in the middle of november for p6 but they also said that it will be available for p7 since october -they kept their word and it is available but only for the chinese versions of p7. So i would expect emui 3.0 for p6 in december for the international version.

Ok, I think I managed to calibrate it, I'm not sure yet, I will update once the battery is drained so I can see how it behaves at low charge, but there are indications that it's working.
If you're experiencing the same problem as me, then you've probably noticed that after your phone drops quickly from 9% (in your case) to 0% and you plug the charger, the battery will charge up to 9% also very quickly. If this happens, then Android is not reading the battery info right and you'll get a 100% reading before it's actually fully charged, and will keep on charging past that point (which I believe is why it stays at 100% for such a long time). It'll obviously drain from 9% to 0% again once it's discharged - because it's not really at 9%, it's much lower.
So, if we can manage to get Android to display normal charging speeds at low charge, then the battery should be calibrated. This is what I've managed to do.
Here's how:
1. Get a Battery Monitoring App (I use Battery Monitor Widget) and set the update intervals to 1 minute
2. Let your battery drain and your phone turn irself off until you can't turn it on
3. Plug the charger and turn the phone on. Watch how the charge increases in this process, it'll most likely charge too quickly (See graph screenshot - blue arrow: a steep slope indicates quick, abnormal charging speed readings)
4. Wait 5 minutes or until it reaches 10-12%
5. Unplug the charger and let the battery drain again. Watch how it discharges, if it charged too quickly in step 3, it'll most likely discharge quickly too here (You can see in the graph screenshot that the discharging slope in this process is also very steep)
6. When it says it's going to turn itself off in 30 seconds, plug in the charger (don't let it turn off).
7. If the 'turning off' message appeared, say, at 2%, your phone will probably display 0% after you plug the charger (i know this makes no sense, but it happens like that)
8. Let it charge and watch how it's charging.
After doing this my battery charged at a normal rate (Graph screenshot - red arrow) and it behaved normally approaching full charge (current started decreasing approaching 100% - green arrow). It didn't stay for ages in 100% after unplugging the charger either, just 1 hour in deep sleep (2nd and 3rd screenshots), which I think is fine because I used to unplugg the charger at night and wake up to a 100% battery, so it seems Android is reading battery info correctly now.
I hope this works for you too, mate (And that it will last more than one charge cycle).
I'll update tonight with low charge behaviour, but I'm pretty sure it'll discharge normally.
EDIT: It didn't actually eliminate the problem, but it got a little better, it now drops from 7% to 4% (instead of 12-13%) and stays at 4 for a while.
So here's a weird thing I'm experiencing:
I left my phone charging overnight, like always. In the morning, I saw the "fully charged" notification, so I unplugged it. To my surprise, the battery percentage dropped instantly from 100% to 96%.
Then, after thinking that maybe I was crazy and it never actually showed the "fully charged" notification, I plugged it in again. The phone said "charging" for a few seconds and then showed again the "fully charged, unplug device" notification. I proceeded to unplug it again and instantly the battery indicator changed to 96% again...
Anyone having this issue? Is my battery messed up already?
Yes that's normal....it's the way the software is nothing wrong with your battery even when it says zero you still have like 30 percent battery left...notice when your phone is dead you can still go into different modes....there used to be a number you could dial into the dialer and it would unlock it to be able to be used. But then when it's needed it's really dead...I think that's why they stopped that or maybe even it still exists and we don't know...but that's normal...that's the way Samsung coded it...every phones battery indication is just what has been programmed not an actual gauge for the battery...HTC is very renowned for doing that...when my phone died I could go into fast boot and it would stay there a very very long time with a bright white screen and even get nice and warm without shutting off...your good dude...

I think to recalibrate battery you have to let it drain completely until it shuts off. Then you have to charge it while it's off until full. Afterwards turn it on and charge until full and it should recalibrate. Someone correct me if I'm wrong.
