Could it be Battery or WM6 problem?

Hey, I have bought myself a second-hand Universal and found it turn off at about 40% of battery. Could it be a software fault?

i have the same problem ( need help plz

i have the same problem ( need help plz

I'm pretty sure it's a battery issue. It has been reported numerous times, my Universal started turning off at ~35% battery after about one year, bought a new one, problem solved.

oh....
Maybe it is somehow recoverable?
I have no money for a new one... in my country they're quite expensive.

i have the same problem in wm5 and mw6

cycling the battery
You could try cycling the battery. Its probably LithiumION. You need to somehow drain it all the way down, then charge it up all the way a few times.
This should bring the battery back to full capacity. Only you can't do it on the phone cuz the phone shuts off at 40%.
That may or may not work. Typical life of a lithium Ion is only 2-3 years.
Ebay has really good deals on them for phones.

It is a battery issue.
Why don't you search a little.
There are some exact same threads already.
Buy a new battery!!!!

All well an good saying look at other threads and "buy a battery" but from my experience I am very sceptical about this issue. I have read many forums on other similar phones and it appears that the Exec seems to be the only model that seems to have this battery issue.
I cannot seriously believe that buying a new battery is the answer, there must be an underlying problem here which allways goes unanswered...!!!
I am now on my third battery, the last one lasted no more than four weeks when it started shutting down at around 75%, and this was a battery from the manufacturer...
My only other option now is to purchase a big blob of a thing which once fitted, will not allow my exec to sit in its cradle whilst on the move...

oh... these Universals seem quite problematic, but anyway I think i'll stay with one a little longer.
I think Universal needs too much power and this is why batteries, which loose some voltage after being drained, are so weak with it.
Some say that when they turn WiFi on, the battery faints at 80% I think it is caused because WiFi module takes even more power.

The problem is, Li-Ion batteries only last around 1000 dis-/charge-cycles. (see Wikipedia) and on WM6 I found no way to disable the charging while connected to my PC. (Okay, I didn't try another cable.) So every time you plug your device to your PC for some minutes, it's like charging your battery and it gets a bit weaker.
Also there's no memory-effect with Li-Ion-batteries so a full discharge followed by a full charge may not bring any results despite of an even worse capacity. You should only do this on the very first usage of the battery.
Wikipedia also says the capacity depends on the age of the battery. So if your dealer sells you a battery he has had in his shelf for 2 years, it won't have the capacity as a brand new one.
Read Wikipedia for more info on Li-Ion batteries. WM6 seems to consume some more power than WM5 and thus the battery shuts down a bit sooner than with WM5. It's really a battery issue.
If you could manage to charge the battery only when it is at around 10%, it will last longer than if you charge it every day or even on every PC connection.

AFAIK there is no problem to charge Li-Ion batteries every day even if it still has any level of charge exactly because there is no memory-effect.

from my experience - WM6 issue
reverted back to WM5 and now it happens at 20% rather than 40% previously with WM6.
try reverting back to WM5 to find if that is the same case for you as well.....

this ain't what HTC FAQ section says. That states the battery can be charged at any level withoyut any detriment to the battery life over a period of time.

overcharging my 8525?

I did a search on this topic but didn't find anything to answer my question. is it possible to overcharge my 8525. can i plug it into the charger before bed and take it out in the morning (usually about 7 hour). also i tend to use 50% of my battery power during the day, so should i go 2 days without charging it and let it drain, or plug it in at night with 50% power and let it fully charge for the next day and never let it really go below 40%. i just want to try and get the best possible use of my battery. any advice would be helpful, thanks

Charge all the time
The short and sweet is that for lithium ion batteries, charge them as much as you can. They are designed for it. Read this article to find out more.

I first read this and thought 'what a **** for asking such an obvious question' - then i read the links from winnebago's and brivent's replies and I realised that I'm the ****. VERY interesting - maybe the links should even be made a sticky.
Thanks for asking the question and educating me from the replies.

It's all in the chemicals
NiMH and NiCad batteries develop memories after repeated chargings. It's the chemicals that are in the battery. That's why it's better to completely discharge these kinds of batteries from time-to-time. It won't stop the memory process but it will slow down the memory formation.
As to Li-Ion batteries, they were designed not to develop memories. One of the side-affects of this design is that the batteries perform better when charged as often as possible. In other words, keep it on the charger until you need it. The major downside is that you should never let the battery dry up. Not good for it.
Most folks mistreat batteries not knowing how they work. Usually they are cheap to replace so it's not a big deal to ruin a battery. However, if you want to get the most bang for your buck, you have to treat each battery type the way it functions best.

thanks for all the quick replys-very interesting and informative links

Charging via car charger while navigating (long GPS usage time)

Hi all,
It is really exciting to see how a new device's forum gets filled up so quickly . (i'll be getting my device sometime today so I feel like a small kid waiting to go to the candy store hehe)
I did do some reading on http://www.batteryuniversity.com/ and also in different parts of the forum.
But i am not sure how this case fits in all of the battery discussions out there. If am going to drive in the states for 3-5 hours a day where i;ll need to use my phone afterwards to continue my day.
Will keeping the phone plugged in the car charger hurt the battery?
Thanks all.

The best to do in order to increase your battery's life is to let it drop to 5 or 10% then plug it on your car charger.
It will last longer then if you keep it plugged on the charger, that's for sure.
On the other hand, the average life of a battery of this type is between 1 year and 1 year and a half.
Personally I keep a second battery with me all the time.
That's what I used to do with all my previous devices so I never be short of battery

Thanks, then i guess i'll play it safe and recharge when it goes low on juice.
If i dare ask, given the scenario where you disrubt the battery while charging, would it hurt it? I read that it is better to keep it charging once plugged in, but then again this is Li-Ion which should not get hurt if you take it out while charging!
Thanks

Not charging in the car
I noticed that when I have my device pluged into car charger and use it as GPS, it does not charge or loose power. In other words, if it is half-charged when I get into the car, and I drive for 2 hours, it is still half-charged, no more and no less.
What is going all?
Thanks

This is correct, but for the good of the battery you need to have it down to 5% (or less) from time to time

I used to have this behavior with my HTC Athena, but did not see it yet on the blackstone. I'll check in the coming days and will let you know

Hi Fadik,
I'd recommend just using your GPS and charging at the same time. Go with BigDede's advice and let it run down a bit before plugging in. This will help avoid possible overcharging.
Compare this with what most laptops are put through - permanently connected to the charger and hardly ever being used on battery. Our Dell still has more than half its capacity after three years of this. If you are still using your HD in 2 years, give a battery as a birthday present!
I don't know of anything that would damage your phone's battery during normal usage. The main battery killers are deep discharge (protection circuits turn your phone off before this point) and very high temperatures (you weren't going to leave your HD on the dashboard of the car during summer while you shop??). Oh, and the obvious, including blocking your car's wheels on a hill, providing canine nutrition, etc...
Hope this helps...

Thanks all for the feedback and input.
and I guess, I should replace the battery every year and a half

This is a common misinformation.
Do charge the battery often. The battery lasts longer with partial rather than full discharges.

Avoid full cycle because of wear. 80% depth-of-discharge recommended. Re- charge more often. Avoid full discharge. Low voltage may cut off safety circuit

No maintenance needed. Loses capacity due to aging whether used or not.

All quotes from this handy table at batteryuniversity.com
So to adress the question of the OP:
Your battery will probably do just fine, as long as the pack itself does not heat up too much from the prolonged charges. The battery it self should be protected from overcharge, and tickle charge should not hurt it.

Im talking about personal experience here
I got my 2 batteries dead in less then 2 monthes on my HTC Athena
due to charging the device everyday while on 50% or more. (Actually charging it in the car, in the office at home, etc ...)
The 3rd one lasted more then a year when I was letting it drop to around 15 or 20%
Again, this is personal experience

I had this same thing when charging through the USB port in the car stereo. I had to revert to the dedicated car charger providing power from the cigarette lighter socket to get it to charge.

Hello
I had some trouble in the past, charging an Ipaq in my car.
You have to check how much the device can provide.
I think the wall charger is giving 1A.
On my USB car charger it could output 750mA. Maybe that's enough to maintain battery level in the case of the HD in GPS use.
I'll check.
You can check how much your usb on your car radio/USB can provide.
But I suppose it's 500mA which is the standard level given by a PC.And that may not be enough.

Car charger problems

I use TomTom on my Touch HD with a car charger.
The first charger I used was fine but since I lost it I cannot find a charger that works properly... At first I thought I was just using faulty charger's but as I have now tried 3 different ones I am beggining to wonder if the problem is with my HD!
The funny thing is that on both the main screen and in TomTom it is showing the status as 'charging'... even the light on the top of the phone is lit to show it is charging but the battery level is still going down all the time!
The only thing I can think of is that maybe the chargers I am using now are not as powerful as the first one I used? Or are all car chargers standard?
Either that or my HD is broken!
Can anyone please help me find a solution?
Ps. The phone still charges fine through both a wall plug socket and a USB connected to a PC.

The car charger I use I bought for my old Tytn 2 (original HTC one), works great for the HD and Diamond, even when the battery was at about 20% left on the HD, TomTom 7 running, screen brightness max, the battery was almost fully charged within an 1hr.
Think it's rated at 1amp, you might want to check the power rating on yours, anything under 1amp and it's really going struggle to charge while using it.

Unfortunately its not printed on any of my chargers what amp they are... I actually thought they were all the same amp but if some are more powerful than others this could be my problem.
What does concern me however is that even when the HD is switched off it is still not charging (even though the light at the top of the phone shows it should be!)

There are plenty of tools around (HTC's battery.exe, acbpowermonitor, battlog, powerguard, etc...) that can show you charge/discharge current. If your car charger gives you less than the unit is consuming, battery will not be able to charge.

I had this problem and found it was because I was charging through the usb socket on the stereo which always worked on Polaris but not with Blackstone. If I charge from the cig lighter socket it works good.

Hi, first post here and rather than start a similar thread so soon, i thought it best to post here.
Is it possible for car chargers to over-charge the device? I bought a cheap and cheerful car charger off ebay but was a bit concerned some of them are listed as having overcharge protection and this one wasn't. Wouldn't normally be bothered but its a £550 handset!
Cheers!

Having another device and cable to carry around works, but is a pain...

my battery easily lasts a day. I can get through a full 9 hour day of work and still have 78% battery left. Not to mention I left my phone off the charger last night, got up 10 hours later and the battery only went down 3%
You sure you dont have any programs open? Also I don't use a task manager if that means anything to u

I bought this, it took about 2 weeks to get to me,(but for 12.99 for 2 batteries and a wall charger) as it was coming from hongkong, but got it yesterday, and its great, 2 extra batteries, and a wall charger so now i dont even need to charge my phone, i let the battery die so i can train them right, and just pop in a fully charged one when needed. the charger even has a usb hookup like the original wall charger that came with it, so really you could charge an extra battery, plus the one in the phone through the usb cable. The batteries are the same as the stock one that came with the phone. I wish i would have done this with my G1, instead of spending 90 bucks on 1 extra battery that didnt even have an external charger.

They are Samsung batteries, they look exactly like the one that came with my phone( down to the details written on the battery, only different thing is the date which was from 6/10 where the one with my phone was 7/10 and the s/n number), so I would say yes it is the same quality.

I got the same type of deal on ebay, 2 batteries & the charger (did the same thing with my MT3G as well), it's always nice having extra batteries, and I can use the charger when I'm traveling (it will also charge up my PSP). Now just need to get a mini to micro USB adapter and I have one less cable to carry around for charging - although I recently got an external drive for data storage, so I guess I will need a second cable if I want to tether my phone and use the external drive.
The batteries are not as good as stock and one seems to hold a charge better than the other (have to mark them so I remember which is which - these are generic one without the Samsung label), but as I train them via charge, use until dead, swap, charge, this should at least max them out a bit. The ones I had for my MT3G actually outperformed the original battery that came with so was hoping for the same. But considering how cheap these are, I could even pick up a couple more.

Those batteries from Hong Kong are not an original Samsung battery, they are just compatibles.
The lasting power of a li-on battery depends not just on the mAh, also the circuit inside the battery counts much of it.
The circuit takes care of the special sleep modes and energy saving features of a battery.
Samsung has its own energy saving codes that can not be put into a common compatible batteries.
This is why an original one is much more expensive than a compatible ones.

Extended battery for the vibrant, lasts twice as long and great door
Check this out: Moretalktime's feedback is 100% and the door is soft rubberized--better than stock IMO. It cradles well in your hand in a very comfortable position and lasts over twice as long.

Re: Batteries not lasting all day
I'd like to throw in an observation on this thread. My battery life is quite good on my Vibrant. Lasts all day easily but there are a couple of things to take notice of. First, I do not use any task killers or such, but I do check if there are any running programs with the built in task manager and stop them once I'm through with them. I've found that Voice Search and Web Access continue to run even after I've closed or backed out of them. Thus the need for use of task manager. But here's what I really found out. I've always charged my phone using the wall adapter with USB cable plugged into it. Never had a problem with battery life. Then for some reason, I decided to start using the USB cable attached to my computer. It would charge as normal and each morning it showed 100% charged. But after about 1 week of using the USB cable from the PC to charge the phone, I started having the horrible battery issues that I've read about. Extremely fast discharge. Leave at 8am and have like 50% use at noon. Crazy. So I started using the wall charger again and the phone has returned to its original state, easily lasting all day. Just a heads up for some of you guys having battery problems. No idea why this has happened but I've confirmed it. Maybe the Power Management thing on the USB ports on the PC?

I just saw this thread after a search on Google. I already posted elsewhere, but this looks like it might be the battery some of you are looking for.
http://forum.xda-developers.com/showpost.php?p=10055333&postcount=80
If nothing else, they also sell a 1600mAh battery which is 100mAh larger than the stock battery and still fits unter the stock cover. Good Luck
