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.

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.
Hi. I have a Voda branded TP2.
I have installed the 1% battery indicator and have realised that the battery is dropping at an alarming rate. In two hours without any data activity, just two calls of 5 mins each and the battery has already reached 74%. The number drops in front of my eyes. Quite scary actually.
Anybody else faced a similar porblem?
2 things I can advice you (as a TP2 beginner)
-First times: charge up to 12 hours non-stop even when light is green (has nothing to do with phone but with the chemical proces inyour battery) this will prolong lifetime
-This TP2 WWE ROM has a lot (and I mean A LOT!) of background running stuff compared to other WM 6.1 - ROMS. So you thing it is not using any current but it is!
Maybe you could install advance task manager and check out all running programs and processes ...
hope this helps ...

Thanks. I have done the 12 hours charging many times - about 6-7 times. Will try the advanced task manager.
Anybody else with a battery problem?
Any application / software is known to be a battery drainer?
Thanks
Had a strange one last night. Went to be, put the phone on charge (was about 16% iirc), and the orange light came on to say it was charging. Then, this morning at about 3am, I hear the phone making bleeps. Check it out, and it's at 5%, with orange light flashing. Take out charger, put it back in, and it starts charging. I went out afterwards, came back about 4.30, and it says it was about 80% complete. Go sleep, wake up about 7.30am, and it's fully charged (green light). Then, I unplug charger, turn on, and it says 96%, and I notice it dropping the amount of charge in front of me (like OP's notice), until it got to about 91%.
Now, about 5 hours later, it reckons the charge is 74%. So dunno why it went down so quickly, and why it didn't actually charge... But will keep my eye on it and see how it goes...
data connection
Another way 2 keep your eye on it: check data connection (start>settings>connections>comm manager) a lot of stuff open this connection which uses power. if it turns on without you knowing .... (especially auto-update plugins (weather?)), sometimes AS also ...

that it isn't a good idea to do "old style battery cycling"
I really don't know what to think of LiPo battery management, so many different theories.
Also, something that annoys me is that I fully charge the TP2 overnight, in the morning the lights green. If I simply unlug charger and plug in back in it well go back orange and stay orange for a good half hour... and I can start again a few times...
To be honest, I had to hard reset my device couple of times and haven't had time to 'fully' recharge it after the resets.
I guess I will give it a few days of full charging and then check on the battery.
But, I am not joking when the 1% battery meter just drops numbers faster than a meter at the gas station.

I had this problem when I have push mail turn on. If you disable push mail and set it to receive like every 15 mins, it save the power a lot.
Try the advance config to auto disconnect every x mins, this will helps as well.
Hi HaveryR and others,
yep your source isn't to bad. Beginning with full charges (6 to 12 hrs instead of 3 like the manual says) isn't about the old charge-memory story (because Lithium-Ion battery don't work this way, only the nickel-cadmium and nimH do) but about fully charging cells.
I mean the best way to look upon this is like a pile of bricks on top of each other (all different cells if you wish). So the first time it is important to give all the bricks enough time to charge - so even when it says 100% it does not mean that it has (you're indicator is a feedback of a reading by your cpu). So not all the bricks (let's say) have the same quality (yesyes even in this day and age of hight teck).
So you can also take this parallel to discharging: if you discharge fully, you risk that one of these bricks get busted and so will NEVER recover.
So i agree on this with your source a LiOn batter is bettery served with frequent partial charging and must NEVER be drained completely

Guys,
I put the TP2 on for charging the whole night (about 9 hours). In the morning the LED was green and the battery meter said 100%. I took the charger off from the handset and re-inserted the tip in. Guess what? 95%.
AM not sure if it is a battery problem or handset problem?
Its come down to 73% with just one phone call of 5 mins. Mail is on, but its on manual and havent pulled anything since morning.
Any idea?
I got my Tilt 2 yesterday. I charged it to 100% before using it, then had it on all afternoon setting it up and adding programs. I charged it all night, but when I got up this morning the battery said 70%.
I went to the power settings and noticed there's an information tab that has status info since the last full charge. The status under Last full charge on my phone said "not applicable". I plugged it in at work this morning and waited a while to make sure the charging light turned from orange to green. It did and the battery power remaining was 100%. I left it charging another hour.
A little later I checked the information tab again. It still says Last full charge: Not applicable. HUH???
Aside from the Last full charge field, it also has stats for Standby time, Talk time and Device usage since last full charge. Since I apparently still haven't had a "last full charge" all the values are 0 on my phone.
Does anyone else have a date and time in that field on the information tab?
i got the same on my imagio.
When I first got my Tilt 2, I noticed that screen and thought "hey that's useful". It had the values all filled in properly. But when I went back later to check it, I saw "Not Applicable" just like you. It seems to be intermittent though, because I checked it just now and it has good data. I haven't noticed any correlated factors that predict whether the info will be there or not.

you should never leave your phone plugged into the charger after it has reached full capacity. you're basically draining the overall battery life of the phone, so it won't last as long off of a full charge.
did that to my old tilt before I found out about the overcharging thing, and had to use my warranty to get a new one since the phone would shut off by itself at 90%+ and turn back on again with >5% battery power left

I wasn't really sure that it was fully charged because of that stupid message about the last full charge not applicable. Thanks for the information. I didn't know that it was possible to ruin a battery by overcharging it.
@enisoc,
I thought it seemed like it would be a useful feature, too. Every single time I check power settings the values are null. It's interesting to know you've seen data there at least twice.
ETA: Now that I think about it, for the last two years I've plugged in my Tilt before going to bed and left it charging all night. Every morning it was 100% charged and I never noticed any adverse effects.

Maybe I've just been very lucky, but I have had a Sprint HTC Touch and before that a Samsung Blade (razr wannabe), each for two years. Every night for those four years, I plugged in my phone before going to bed and left it there. I have always had great battery life on both phones.
Specifically for the TP2, I have read that it stops charging at some point when it's done, and won't trickle even if you leave it plugged in. This has been reported by various people because they find that if they leave it plugged in for very long times, they'll end up with only about 95% battery, because after the first few hours it was no longer charging.
Perhaps less convincing, but also interesting, is the fact that (when it works) the "last full charge time" on my TP2 shows up as a couple hours after I went to bed, rather than the time when I unplugged it in the morning.
YMMV

oh wow really? that's interesting. that would be nice if it's really true. what I've been wanting is an app that allows the phone to make some sort of noise (i.e. an alarm sound) when it is fully charged. just to let it's owner know that it's finished and so it won't get overcharged. I think i'll go request it at development n hacking.
I am 100% sure that you cannot overcharge a TP2, in fact I would say any phone or device with a Lithium Polymer battery.
..........
it's true, once the TP2 hits 100% it stops charging the battery & the usage time will kick in.
Day 3 and still no data in the battery power information tab.
do a hard reset. mebbe itll work.
Since its very new, you got nothing to lose.
flip, do you have a TP2? If so, does that tab give you data all the time?
yes, its a Tmo TP2.
it worked on the Stock rom.
I have a custom rom now, and it works as well
once the green light comes on on the touch pro 2 u it stops charging, u cannot overrcharge it
Not only can you not overcharge the lithium Ion batteries it is actually better for them to be recharged as often as possible.
Menneisyys wrote a great article on it a while ago. This confirms what I have always been told.
http://forum.xda-developers.com/showthread.php?t=342162&highlight=battery+charging
Overcharging li-ion (and li-po) batteries results in catastrophic failure, a.k.a. explosion. Therefore, chargers for these battery chemistries stop charging when they're full.
Something is wrong with ne WM6.5 driver!
Yesterday my battery duration was about 24h (with 6.1 i charge it every 2-3 days!)!!
I fully charged at midnight and now, after 15h it says 90%... It's a little bit strange!
At midnight i could see battery stats.. Now it says "not applicable".
I used Dr SigStat and it says a temperature of 2,47°C!!! (in WM6.1 temperature was normal).
What's wrong??
Over the weekend I finally got some data on the information tab. Either Saturday or Sunday morning when I checked it gave some time around 5AM as the last full charge time. Now it's back to Not Applicable.
@D J Palmis,
I wonder if anyone knows the answer to the 6.5 battery dilemma. When I was using a cooked 6.5 ROM on my Tilt I was getting normal battery duration. My battery life on the Tilt 2 is comparable to my old Tilt.
i see this on my tilt2. battery info shows up, with idle/usage times for a short while after full charge (green) if i check after a few hours, it goes to n/a. looks like a driver bug to me.
I have purchesed HD7 4 days ago. It never charges 100% even if i leave it on charge for whole night.
Any solution.
how do you know it doesn't? the battery icon isn't exactly specific? but if it doesn't, take it back to the store you bought it from.
The phone stops charging before 100%
Just like other phones it has battery indicator in the form of cell/battery.
It should appears filled/full when charging is full and as the battery drains it should gradually appears empty. Now the issue is that it never appears full. The extreme right side of the cell/battery always stays/shows empty.
In other words we can say that the phone stops charging before 100%.
Beside this the indicator works fine and the battery life is also ok.
I bought this phone in UK and currently working in dubai so I cannot take it back to the store.
This happened to me, for the past week+ (I bought the phone on 28th).
I don't know why but an Overnight Charge didn't seem to be long enough for it to charge fully, it was always nearly charged.
However, This morning it seems to have charged 100% so maybe it's just a matter of time? Maybe the battery isn't in sync or something when you first buy it.
Think the battery icon is a bit dodge. As long as you get the green indicator light you know it's fully charged. If it's still orange then still needs topping up.
I've not had a problem charging myself but what I have found is that sometime the indicator says it's nearly dead. Reboot and sudenly there is an increase in amount of battery left. Very odd.
Maybe you need to wait a few weeks just to let it settle.

That isn't acceptable for obvious reasons, so I hope that isn't the case.
P.S. 14-30 day return/exchange policies.
All right Dudes!
The problem is fixed. Simply fully charge your mobile phone and then full discharge till it turns off by its own. Repeat the procedure three times and you are done.
Good Luck
I have the same issue, if you turn the phone off and back on when the light turns green, the battery icon is then full.
So seems like a software issue to me.
My HD7 is going back tommorow anyway, keeps resetting itself and when trying to video in 720p it looses focus!
I previously went back to O2 store the day after i bought the phone about the original charging issue. They were going to swap the phone but then had no stock. Then my above issues topped it today so took it back and surprise surprise they were out of stock! Apparantly expecting a delivery tommorow but they don't know what they receive till they get it (BS i reckon) so if they don't have any in tommorow I'm getting a refund and going to go for a Venue Pro or just stick with WM 6.5..

How do you "full discharge" the phone? Use it until the battery is complete dead and charge it up again x3?
Yes, use it till battery is fully dead and charge till charging light turns green.
That never worked for me either, infact last night when the phone was flat, I have left it on charge over night and it went green, but showing about 50% charge, turned it off and back on and its then full.
My phone is doing this as well, now. Charges to full on teh charger. Take it off, adn it goes straight to 75% charge - viewable in the Battery Saver by battery level. It's impossible to charge it fully, and battery life is TTEERRRRIIBBLLEE.
Either something is wrong with the phone or firmware, or the OS. Not sure. But I can't use the phone like this. It's as if it has a 920 mAh battery in it. Obviously that shouldn't require anymore explanation.
---------- Post added at 11:25 AM ---------- Previous post was at 11:14 AM ----------
Follow-Up: I'm convinced it's a bug in the WP7 OS. When you charge to full, and take it off the charger, it instantly drops to 75%, then if you put it back on the charger 20 minutes later it goes to 93%?!
Problem is, the OS is set to shut down service, etc. when battery power is low (even beyond the battery saver setting, IIRC), so the bad information the OS has can hamper usability. It's basically cutting 2 hours off your battery life when you unplug the phone after a full night/day's charge.

And kill the battery, forgot to say.
Charge on the wall charger, not PC USB.
Hello,
My desire, after:
an inability to restore nandroid backup
a possible corrupted sd card
a usb brick and inability to mount some nand partitions
and finally succeeding in fixing it, now using/running:
2.29.405.5 stock rooted rom
a new sd card (samsung 16GB class 6)
clockworkmod 2.5.0.7
s-off
seems that has battery issues. When it reaches below 30%, it drains a lot faster. In example few minutes ago, the battery was below 30% level and after sending a couple of sms messages the phone, without the "Connect the charger" indication shut down. Not even the battery icon was red.
What should I do?
After flashing the above ROM I ran an app called battery calibration (could this be the culprit?).
I haven't experienced such problems before the whole mess mentioned above.
Thank you for your time.
Well, it seems to me like a "classic" battery meter calibration issue.
TVTV said:
In order to calibrate the battery meter - FYI the battery itself cannot be calibrated, as Li-Ion batteries have a very low memory compared to old Ni-Cd etc. batteries - you have to go through the following procedure:
1) charge the battery to 100%;
2) let the battery discharge until the phone shuts itself down;
3) plug the wall charger into the phone, boot the phone up then charge the battery to 100% without interruptions.
If the above procedure does not yield the expected results, you can try fully charging the phone (LED showing green) with it completely turned off (after completely draining it). Again, the charging procedure should not be interrupted.
Source: personal experience - had to do this twice after installing new ROMs, as the phone was shutting down at ~14% (working like a charm now).
Regarding the matter of battery wear because of complete discharges, Li-Ion batteries do indeed have a lower cycle count than old-school batteries, but the standard charge/discharge number a Li-Ion battery can take is ~350, so you can't damage the battery pack by doing a full cycle per month (required to keep the battery meter accurate).
Good luck!

Did this work you mate? I have the same issue with my year old batter now... the phone shuts down @ 40% without any warning... and when I charge it, it starts from 0% and as soon as it hits the 58% mark, it jumps to 100% by itself... and i cant seem to figure out what the hell could I do to fix it... I tried calibrating the battery using the awesome method described here http://forum.cyanogenmod.com/topic/11823-battery-calibration-thread 3 times and nothing changed...
bump bump.. i really need help on this guys... :/
Sent from the infinity and beyond...
Weird that after calibration you still get that kind of issues, does this only happen on your current ROM? I have the latest CM in my desire and everything works just fine... Maybe try another ROM if calibration doesn't work to see if it's a hardware or software issue
i actually had issues with MIUI first.. the phone randomly shut down by itself but when i turned it back on, it was perfect... then i switched back to Oxygen and while everything was fine, suddenly one day the phone died at 40% :S and from that day on the phone charges to 58% and then instantly jumps to 100%... and as soon as it gets to 40% it shuts down itself... i guess i need a new battery but i wanted to see wether i can fix this one somehow so i can use it till the new one arrives...

phone turning off at 20% is fine mate because thats the battery guards against any damage
most of the phones ( smart phones) switch off at 20% as going lower can damage the System .
It shouldnt normally..It's supposed to work fine upto 5%
Have a look at this, it worked for me (but you need a compatible kernel, most AOSP are so)
