Battery drain... funny problem

Hi All,
Got this funny problem since I have flashed TNT WM6.1.
My mobile battery shows some funny traits.
1. It can suddenly go off (even if the bar is at 87% or 63% or 30% or anything of that sort)
2. Once it goes off, it gets into a loopback of restarting the device, goes upto the screen where WM6.1 logo appears and restarts again.
3. The only way I can then get it restarted is to get it to plug to a powersource.
4. When I plugin it shows within 5 min that the battery is fully charged.
5. I use audio manager a lot and its like every 30 seconds 1% of battery is gone.
Have search through the forum but haven't found anything like this.
Anyone has face a similar problem and found any solution?
Any help will be much appreciated.
I am on SPL/IPL 3.08.

Time for a new battery....
I ran across the same problem. It turned out that the terminals on the battery were seriously worn down so much that the battery couldn't hold a charge to safe it's life let alone mine!!!! I went to a battery store and replaced the muthaf^$#a!!!!!
Go grab a new battery and you'll be electric sliding again in no time!!!!

Thanks Trej3k. Much appreciate your response.

Yeah
Had the same issue.
Replaced the battery ... and now everything is fine.
Now I don't expect 5 days without recharge but at least 2 days.
Along with the new battery I bought an battery charger so now I can use two batteries.
The nice thing is that the old battery is lasting at least as the new one, Maybe because of the charging more regularly and not so frequently and because both batteries never go in usage when they are hot of charge.
Try your thing

I had the same problem pretty soon after I flashed my ROM for the first time. I would charge to 100% and then browse the Internet or take a call, and the device would reset within a couple of minutes b/c it would think it was out of power. The timing may have been a coincidence; I don't know. I bought an extended battery and everything works fine now.

I had the exact same problem right after flashing to wm6. I really wonder if it's a coincidence.

I ordered a new battery today because I have exactly the same problem. I also apeared after flashing WM6.1 a while ago an became worse with time. Since my battery is 3 years old, it could also just be a battery at its end of life...

Slow charging

I have decided to move this post from the issues thread to a dedicated one to give it better visibility. If no one else is getting this problem then I will probably return the device.
I have the excellent "devstate" today plugin application installed which gives the battery charge level in 1% steps. When I say slow, it takes around 3 mins to increase by 1% which means it will take 4 hours for 80% charge (too long) when this is the case, the back doesn't heat up.
I have seen it charge much faster on one occasion i.e. around 1% a minute and the back was warming up (this is logical if more current is flowing) I was wondering the cause of the slow charge is that the device thinks it is connected to a pc and the charging current is limited. Also when you plug the cable sometimes the menu pops up asking whether you want to enter activesync/disk drive mode but doesn't on other occasions. There doesn't seem to be any pattern to it.
Another observation is that a soft reeboot occasionaly gives wildly varying battery levels for example before reboot the charge might be 100% and straight after the reboot 90%, or 83% before and 100% after. Interestingly before turning on the device for the first time I fully charged the battery, but up on boot up it was reporting 60%! (maybe it didn't charge at all when it was switched off and 60% was the initial amount of charge the battery came with) Have I got a duff battery or some issue with the device itself?
I seems like the battery charges fast up to 75% at around 1% a minute but then slows down to 1% every 3 to 4 minutes. Maybe this is the charging profile for this battery. Has anyone else noticed this?
Here are a couple of threads from the diamond section regarding the sort of issues I am experiencing but there doesn't seem to be a conclusive fix.

Could people please answer the following questions to help me decide whether I have a faulty device/battery or some ROM issue which all of us have. I have the stock UK touch pro ROM 1.90.405.1 WWE.
1) If you fully charged the battery before powering on for the first time, what was you battery charge level immediately after power on?
2) Have you noticed fluctuating charging rates?
3) Soft reboot gives different battery charge levels.

Just a quick Q, which charger are you using? Can you just post the amp / volt data printed onto it for us?

I am using the one that came with the touch pro, model no TC P300, its output rating is 5V at 1A. Input rating 100-240V
I have also tried the mda vario III charger and I get similar results i.e. fast charge up to 75% then slow afterwards.

As i stated in the other tread with the "Raphael issues" i have the same problem.
When i use the shiny new charger with the "usb-mini usb" cable i takes 7-8 hours to completely charge the device. (output is 5V-1A)
However, when i use my good old Hermes charger, or any other 5V-1A charger, it goes to 100% in about 3 hours.

Mine charges up to 90% from 10% in less than 3 hours after which it stays @ 90% (According to the built in battery meter of the device) forever. Is it a faulty battery or its supposed to be like that?

And do you get varying battery levels on soft reboot?
3 hours is probably what I would get i.e. "75% at 1% a minute = 75 mins" PLUS "25% at 1% every 4 mins = 100 mins" giving a total of 175 mins.
question is that is this behaviour normal for touch pro or only present on
some device/battery/chargers.
I also have another issue, this time regarding interference on speaker, see this thread:
http://forum.xda-developers.com/showthread.php?t=419761
If only my touch pro has these faults then I want to replace it asap, especially when having paid £500 for it.

Yes i do get varying levels on reboot, but i got that with my Hermes and Magician too. So i wouldn't worry about it. Usually when you softreset while it's charging you get a higher battery reading then you should have, but it wil drop after some time to it's real level.

This happens when its not charging. I don't get this with the vario III. Maybe it is ROM dependant. The other concern was after having charged the device fully when switched off, it reported 60% on power up. I might let the battery drain to a low level then charge when switched off to see whether it charges at all. Some diamond owners were also reporting this.

Hmm, got the same thing tonight with my Hermes charger, has been charging for 6 hours and still not fully charged, now at about 80%. Very strange. Are there more people experiencing this?

This didn't appear to happen to me on the first charge, but I turned it on immediately after putting the battery and SIM in place, and then I charged (I don't remember what the initial battery charge was). I've not noticed such wildly inaccurate readings after reboot either. I haven't specifically checked for inaccuracy in the battery meter, but I would (probably) have noticed such a big difference.
Have you tried to do a full discharge and charge cycle? This is necessary after around every 30th charge to recalibrate the gauge so that it is as accurate as possible. I know yours probably haven't gone through 30 charges yet, but it may be worth trying.

This is normal for lithium-ion batteries. The last 20% or so can take as long as the first 80% to charge.

When charging I usually leave mine overnight, so I think I've only charged it once during the day, and then I think this was through USB while connected to the PC so it may have been a bit longer than 'normal' (3-4 hours) for that reason. I'll keep an eye at it next time I do it during the day.
Six hours plus sounds far too long though, do you have a chance of trying the battery in another device, or another battery in your device?

Nope, don't have a second Touch Pro around here, but this is really annoying, I need a fully charged battery in the morning. If this is hardware related i'd return it to get a replacement.

hmm, this is interesting.....so just to clarify we are seeing slower charging with the bundled adapter: which is essentially an AC to USB power transformer?? If the USB port on that (yes i know its power only) is capable of supplying only a standard ammount of juice then your battery may charge to 100% as slowly as from a pc or car charger..
..id like to perhaps see if i can meter the current and voltage coming from it but would need me to cobble together a breadboard with the relevent power points.
Is the hermes / kaiser charger charging it fully in less time?? (to clarify)

Yes I drained the battery till the phone switched off by itself but still have this problem. I suspect there is a problem either with the phone itself or the battery as supposed to a ROM issue. I thought all the clever charging circuit is in the battery these days and it's the battery which reports it's charge level to the device too. If this is true then probably the battery is faulty but I am not going to buy another one just to find out. I'll try to get a replacement for the touch pro tomorrow when the shops open.

It is, but even so the gauge (in the battery) needs recalibration once in a while, hence the full discharge/charge cycle every 30th charge or so (other than that it is recommended to charge li-ion batteries often, and not deplete them fully).
Your next port of call is probably to see if another battery makes a difference.

Today I charged my phone from empty to full while connected to the PC, which took around 3 hours 30 minutes (phone not used except to check charge levels towards the end).

the charging cycle on mine has been a little erratic too.
I put it on charge at 9pm last night, at 6.30 this morning it was at 88%. 9 hours and not fully charged!!...still, 3 hours later and it's on 87%. so I think its more a case of requiring a few charge/discharge cycels to settle the guage down a bit.

This night it fully charged in 5 hours. While yesterday it wasn't completely charged in over 8 hours. There doesn't seem to be a pattern in this.

Yesterday it was showing 48% battery level at one time, a soft reset later 28%, another soft reset and it was 24%. Today I have sent it back for a replacement. Can those people affected by this issue please state where they bought it from, in order to figure out whether it might be a faulty batch. I bought mine from clove technology in the UK.

Mine came from Expansys.be, please let us know your new unit has the same behaviour.

Will do if I get a replacement one, they have satisfy themselves that there is fault first. Will probably take around 3 days. I miss my touch pro already.....
Oh well back to the vario III for the time being, seems cumbersome already in comparison.

Hermes Charger

Whilst I don't have any exact figures to hand, my hermes charger took about 45 mins (Give or take a little.)
I've been using the standard Raphael charger today and charged from 50% and it's still going after 1 hour 20 mins and only at 90%
I know the final 80% takes a lot longer, but even so.....

Strange battery behavior...

Today when I woke up, the battery was 40%. Not TOO strange (I am not very sure how much I left it last night) but strange.
That is not the problem though. The problem is that 3 minutes later while I was playing some backgammon on the device (don't ask), the power was already 37%.
Since daylight savings today, must have confused a couple of apps in my device (notably Klaxon - will post in its thread for that), while I was playing klaxon I got some delays so what do we do? Soft reset of course.
This is where the strange thing happened... After soft reset, just a few minutes after the 40%... I got... 23%!
Anybody noticed something like that?
I usually don't let my batter go so low (li-ion batteries don't like low numbers), so I don't know if this is a known issue.

This is a common problem, check out the other battery threads. The battery maagement on this device is a little suspect. A soft reset usually results in a different battery level - some people including me sometimes find chargin stops around 87% however a soft reset will give 100%.
Hopefully a new rom update will provide better drivers.......but only if people are telling htc about it.
A full discharge in every 20 charge cycles is recomended as posted in other threads, in order to calibrate the battery indicator.

ok thanks man

That capping at 87% thing happens on my Elfin. When I softreset, it's 100%. Though it doesn't always happen.

Does battery status read accurately on your device?

In the Raphael Radio thread(http://forum.xda-developers.com/showthread.php?t=439566), someone said:

Try soft resetting the device and see if the charge holds.
I was impressed mine was only down to 50% by the end of the day, but then i did a soft reset and afterwards it read as 28%

I also have this kind of problem on my device, but not it doesn't occur every time on these situations. In further research, I find out only some of the batteries (I have 3 original batteries for the device) can't read accurately. Does anybody else experience this problem?

I also have this problem.
HTC support seem a bit oblivious to it however and gave me no help.
seems that after a few reboots, once the loss of charge seems to settle, ie only going down by say a few percent each boot, then it is stable, and once given a full to 100% charge, which can take more than overnight (if you leave the phone on - which it seems you have to, for this to work) then it holds a charge well.

Yep, same problem here as well. It seems to have started with me over-loading the battery. Afterwards it showed a bit of variation before and after a cold boot. However the differences are not that extreme (+- 5%). Also I noticed that temperature plays quite an important role.
Maybe also the battery % tweak has something to do with it, but I cannot confirm this.

I've also noticed this. But I think that the battery reading is never fully accurate and never was on earlier devices either. It's only the detailed percentage reading which is now possible on the VGA screen that makes us noticing it.

I always use other utilities to view battery status in percentage for years. On my previous devices, from Magician to Kaiser, percentage was going down all the time, but on Raphael, sometimes the percentage just freeze - It means, the percentage stayed on like 73% for serveral hours but after I soft-reset the device, the percentage reads 49%. So this problem is more than inaccuracy, actually it may be a hardware bug.

I've noticed that after charging my TP for around 2-3 hours the battery will be fully recharged, even though my TP is reporting it only being as low as 50 % charged. If I just unplug it at this point, and start using it normally, the battery reading is highly inaccurate and often freezes for several hours just to take a ~20 % dive later. However, if I do a soft reset after charging (no matter if it's fully charged or not) I feel I can get fairly accurate and consistent battery readings. Also, if I've been charging for ~3 hours, the battery reading may well say it's only 80 % charged, but after a soft reset it's gone up to 100 %.
So, for me, a soft reset after every charging period keeps the battery reading quite accurate.

I've been noticing the same problem with the soft resets from all my ROM flashing. I've also noticed that it pccurs sometimes when texting or using the internet. I'll send like one or two texts and my charge drops 5%. I guess the thing that calculates the battery charge uses some weird algorithm that doesnt work correctly when the phone is essentially idle.

[Q] Restarting the phone gives MORE Battery?!

Yes, this is exactly what I get lots of time. Today, I had been charging my phone for around 3 hours starting from 14% battery. Till now it had reached around 55 % when I had to remove the charger and I put my phone somewhere. Then after some minutes I connected my phone to the PC to charge via PC now, as the charger was unavailable to me for the moment. I found that the phone had been turned off automatically. OK, so I turned it on but I saw that the battery is 100% !!
Similar thing happened yesterday when I was charging phone and decided to restart mobile thinking of getting more RAM, for it had not been restarted since a while. I restarted at 20% battery and turned it on to find that it was above 50% !
Why is it happening? Does my battery get charged quickly but phone does not tell me or is my battery behaving funny? (actually, not funny at all)
My brother's HTC Amaze charges from zero to 100% in around 2.5 hrs and other brother's Xperia Arc also charges from zero to 100% in around 2 hrs.
But my Sensation normally takes 5-6 hours.

This is a known "issue" and is due to (closed source) htc drivers. Those jumps are rather large though, could also be due to bad battery calibration; something to be expected just after flashing a rom.

I have never flashed or rooted.. didn't they give a solution?

Actually it happens even if you're completely stock. It's a known issue in everyone sensation, i think. I also think It won't give you more juice as percentage will reduce faster to where it should be.

That's what I experienced yesterday.. it dropped down real fast.
As mentioned above, it may also be a calibration issue. I am saying this because I sometimes charge with charger and sometimes with PC (USB charging Mode), and even sometimes switch between these while going from 0-100%.

I think it doesn't matter how you charge or deal with your phone. I don't think that battery calibration will solve it. If you reboot it'll increase your battery percentage, even if you don't use a charger.

it is a common htc issue with battery percentage
it happens with my device too
while charging if i do a reboot it jumps to a higher percentage
