Battery Problem

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 ...

For indo, it says here (amongst others)

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?

Last full charge status = Not applicable???

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.

Charging problem! slow or no charge..

ok, over the last week or so ive had this issue, gradually getting worse...
my battery will charge to around 40-45% and then charging will slow right down.
two hours later, it will be on around 50% if im lucky, and about 3 more further hours before i hit 60% (this is some of the time, other times, it just remains on its current charge%)
if i leave it overnight for about 10hours or so, highest it goes to now is about 73%, but this is rare, usually 45-50%ish.
ive tested with htc ac wall charger, htc usb, blackberry charger, car charger and a random microusb wallcharger. all have same issue.
when tested with two friends desire hd's on different days, my battery charged perfectly, and at the normal gradient speed over the % range. and my phone reads it correctly at the 100%-98% when back in my phone after change back.
i thought it was down to my phone, just dont know if its rom or hardware. shud i factory restore, or claim on insurance?
i have another issue here...http://forum.xda-developers.com/showthread.php?p=18480603&posted=1#post18480603
which also applies to the question of restore or insurance...
thanks

What Rom are you using, i am using runny 2.2 only 62% charge in 6 hours
9 hours later on battery only upto 68% i have amazing battery life now

i'm using runny 2.2.....left it on charge for 2 hours with phone on, but wifi and everything off and it had only gone up 2% ! !
Turned phone off and plugged in charger, 30 mins later, only went up 1% ! !
72% charge at this point.
So took it off charge, put it in my pocket, went upstairs to bed, turned it on to set alarm and it said 100% on battery....weird!!

Lol this is an issue with calibration. The battery is charging but the software doesnt report it.
You have to charge the phone for as long as possible so you know it is on 100% whether the software says it or not, go into CWM, wipe the battery stats and then let the battery drain fully until it shuts down by itself. Then plug it in and leave it until you know for certain it is at 100%. If the green light comes on leave it for an additional half an hour. Then it will be fixed.

ive only recently got this handset, as last one was replaced on insurance a month or so ago, and its runuing on stock rom with latest updates....?

Phone shuts down at 14%

So, I bought another battery. Will this sort it?
Also, what's the usual procedure?
Should I charge the battery to full in the phone (turned off) then boot, set up, then charge again and reset battery stats?

The problem is that the battery control chip doesn't take into account that the battery ages.
Resetting battery stats or charging while turned off will only clear the stats you see in the settings menu. This guide will make your battery drain to 0% again: http://forum.xda-developers.com/showthread.php?t=1534892
I don't know what a new battery will do though.

I gathered that, but as the phone is going to a new user (my stepson) we got him a new battery anyway
I just wondered what the correct procedure is. I know you need to do a first charge with a new battery, as with a new phone, however, this phone obviously has a working ROM already on it.
So, the phone is charging now, switched off. Should I turn it on, use a little, then use the battery calibration app to delete the stats and then drain to 0%?

Well, that assumption is probably inherited from the NiHM batteries in the past, because it's not needed with Li-Ion batteries. In fact charging to 80% is better than charging to 100% and keeping it plugged in.
You can read more about it here and here.

Just charge it and use it for a full cycle. If it shuts down at 15%, you can try the battery calibration from the thread I mentioned above. If it doesn't, you're battery capacity is the same as the one the battery chip has calculated, which is good.

So, why does the first charge take so long?
This thing is still charging and it's been on the charger for 3 hours, whereas usually it'd be charged fully by now.
Been like that for every Li-Ion battery I've ever had (including my S3, took around 6 hours to charge, usually takes 3).
EDIT:
Just to clarify, I don't intend on leaving it past the green light. As soon as it says it's full I'll be taking it off charge and not trying ot overcharge it. But I still have the orange charging light after 3-4 hours.

To be honest, I don't know. Maybe it's a safety to prevent overcharging. Coincidentally, I've got exactly the same issue now. I asked about it in the calibration thread. I suppose it's normal, but I'm not sure about that.

my battery took just over 6 hours to charge the other day from completly dead
Sent from my HTC Desire

Phone dies now around 10% ?

Very odd ever since the phone died since it was really cold out ( i left it in car for a few seconds and looked at my phone and it was dead ) its been shuting off or dieing around 10% left but drains normally. but can still turn it back on once its plugged into a wall charger. so im not sure on what to do cause i mean i only had it for a year now.

it happens with mine too, 2-3 weeks ago.
I had 40%+ and after few sec, was dead too.
I turn it on with 1% battery lol

was thinking of letting it die once then letting it cable charge not fast charge saw a video for an older phone to do that with some call code to reset the battery gauge

I have the same problem since a few weeks.
The percentage drops from 15% to zero.

Mine was a bit different, I was in 13% and then when I plugged in the cable to charge my phone, it showed I was actually in 6%. My friends, our phone is aging

Since it became cold outside I'm having the same problem

Yes
I had this problem with my Galaxy A5 2016 and now with my Galaxy S9...
Never go under 10% if you can't charge within 1 minute or better less. That's why I have a battery case.

So I think I fixed mine a video is for a note 4 ut I think it worked for mine also. Make sure your phone is almost dead and turn off fast charging then go to the phone dial up (built in app) and dial *#0228# and click the quick start (this will restart your battery gauge) let it die then charge to full might take longer but it's worth it.
