Simple questions to the long story I wrote below the line(didn't realize it was so long):
I have two batteries that get a red light when trying to charge and they will not charge. I'm using a travel charger that came with the phone (used, not sure if it is the original charger). Input is 110-220V 50-60Hz Output is 5.5V 500mA. Says model T-HT-8125-SH on it.
Based on my findings, the phone should charge with 1.0A so it makes me think this is not an original charger. Old posts stated if the battery was this empty you need an original charger since it is the only thing strong enough.
The second question regards a new battery (just bought - one of the two above) dropping from having about 50% to having 0%. This is described in the story below, but could switching batteries / putting in a dead battery anything like this cause the new battery to lose it's charge all of the sudden? Or could there be damage to the phone other than the battery causing this issue?
Anyone have experience with this? What specs on a charger am I looking for that match the original charger? I may find other mini USB chargers around and if I have one that matches I can try it. I just don't want to damage the phone.
------
I have a wizard I bought used a couple months ago. It worked fine until a water damage issue occurred. I let it dry out for a week and then it was back to working fine. The only thing I noticed afterwards was sometimes the battery would drop from about 75% to 25% really quickly when it did not used to.
Last weekend, it was charging overnight and in the morning it would not turn on at all. I tried taking the battery out and trying to charge it again without success. The orange light usually does not come on. I either get no light, or a red light. Sometimes the red light stays, sometimes it blinks, but usually it is red when I first plug it in for a couple seconds then goes away.
I read recently in the manual that red means it is in LDO charging mode, thus the battery is empty. I thought the battery was dead so I ordered a replacement. It arrived, I stuck it in, it worked.
Now the weird part - I let it charge some on the new battery (it was around 18% when I got it). Then I decided to test the old battery and make sure that was indeed the problem. The phone wouldn't turn on or charge. However, I put the new battery back in and there is no charge. I tried charging it and the light was orange as it should be. However, after a couple more battery switches (I found out about the red light / orange light from the manual at this point so I went to test that with the old), the new battery is acting like the old battery. Both get a red light and will not charge.
Any ideas?
No answers for you but -
My original HTC charger has the following stats:
HTC p/n 70h00051-01
Model ADP-5FH B
Input 100-240v~0.2A 50-60Hz
Output 5V 1A LPS
Thanks for the details. I suppose mine isn't an original charger as it only has half the power yours does (and is a different model). It is probably some generic third-party charger.
For anyone interested, I did manage to get the phone charging by jump starting the battery with a 9 volt battery (saw an old post about it). Just connect the positive terminal of 9V to positive end of battery, and negative end of 9V to negative on battery. I used the metal from the inside of twist ties to connect the two batteries. Hold for about 15 seconds, then see if it will charge. If not, take battery out of phone again and use the 9V for another 15 seconds..See if it will charge afterwards. It only took a couple tries before it had enough power to start charging with my charger. Just don't hold it too long as the 9V is nearly twice what you need.
Anyways - it's charging now and is at 80%. We will see if it works like it should afterwards. If so, then I will have two working batteries for the phone.
Note - this shouldn't be an issue with an original charger that is 1.0A. It seems the third party ones are less (500mA, or my car charger is 650mA). I imagine the original charger is strong enough to get it started even on a completely empty battery. If not, the 9V battery sure is.
Just an update - not sure what is going on. It finished charging and the light turned green. As soon as I unplugged the wall charger, it dropped down to 51%. Ok...so that was weird...maybe it wasn't really charged. So, I let it charge up to 100% again. Light turns green. Unplugged it, dropped immediately to 39%.
Anyone have any idea why it would lose a large amount of charge when I unplug the cable? I'm charging it for the third time now...I'm not sure what is going on.
This is all with one battery (the old one). I haven't done anything with the new battery yet to try and get it to charge, but this might explain how the new battery lost the charge it did have and became empty like the original battery - perhaps it lost it's charge when I unplugged it just as the old one is doing...in which case this seems like a phone problem...hopefully not though.
Well the title sais it all.
Mine take 4,5 to 5 hours to be fully charged from FULLY empty (I wait till the phone switches off i.e. Battery level = 0%).
I find that toooooooo long
Is it just mine or do your HDs take so long as well?
I must add I'm charging the phone via normal electrical power not via USB to PC.
I believe it may not be advisable to fully drain your battery all the time to charge it. We are all using lithium battery these days and not nickel cadmium battery. Hence, there's no issue of discharging the battery prior to the charging.
A new battery will take slightly longer to be charged to reach its full potential and capacity.
If it's taking that long, you may want to check whether you're on the right voltage settings of your charger.
I just let it fully drain twice (I still belong to the old school of fully discharging and recharging your batterya couple of times in the beginning).
Voltage settings are fine.
hi
what the recommended method to charge the new battery?
1)charge few hrs till full and drain till 0% and charge again?
2)charge >10hrs?
I used to have N6288, it will auto stop charging when full.
Therefore i tend to charge my hp before i sleep and wake up in the morning to off the charger. So which is like charging for >10hrs.
Since i do not own htc before, so i'm not sure about how they charge.
lets say if battery full till 100%, will it auto stop charging?
i only afraid with my charging pattern (charging while sleeping) will make htc batt spoilt.
any advices?
thx alot

Of course it will stop. Every battery will stop charging when it will be full otherwise it would burn or explode.

i see..thx
so how long u charge the 1st time?
Before when I bough Tytn II, I charge it over 10 hours and that works well (3~4 days). Recently I bought HTC Touch Cruise09 and I only charge it for 3~5 hours (because the LED turns its color and I just remove the charger). I will see how this battery works.
How to charge a new battery... the solution. ;-)
Hi,
As erzketis says, you have an internal tools wihc switch of your charge.
I'm an electronical technician...
As the charger is a 1Aand the battery is a 1.1 Ah.
In two hour maximum it should be OK.
For me, I went to the sport and 3 hours after, it was OK.
What we usually forget to says is 2 things:
- After the first charge try to use at maximum your battery, let put it close himself (memory effect even if we says taht Lithium has a minus effct, it's a bull****). Try to reperform the same thing 5 times before going on the second tab...
- Avoid to charge you phone when it's not necessary (desactive auto charge when connected on USB). I'll says, wait till 10~0% to charge it. I know it's not prctical, but you'll have a better battery life.
I hope it will help you.
I've been experiencing problems(like most) with battery life on the Epic, so I found a thread here from the EVO forums about "recalibrating" the battery. It involves steps of fully charging with it on, removing cable, powering down, plugging back in, etc...
Well I've actually come to realize that a blue LED should turn on when the battery is fully charged & the phone should stop charging(duh). Well i've tried for the last two days for the blue LED to come on after countless hours of charging, resetting the phone, etc. I've now had my phone on the charger for 8+ hours & my battery widget states 100% yet it continues to charge!
Has anyone else experienced anything like this?
No, but my wife's battery would drop immediately from 100% to 75% as soon as it was removed from the charger. This occurred no matter what charging regime I tried. I know that the battery may start to discharge after its peak charge has been obtained, and that it is possible to remove the charger and see only 90% on the battery, but 75%?
I returned that battery last night and now today I see that this battery never gets past 98%. I'll give it a day or so to see if the battery life degrades again, in which case I'll know it is the phone and not the battery.

Are you getting the blue light and what app are you using to tell what percent? There are other thread that say some of the battery apps are off a bit. What kind of battery life are you getting?
Success!
I used a few different apps to tell the battery charge so it wasn't the apps.
I found a fix that not only allows my battery to charge to 100% but also seems to give a better charge. Since doing this my battery shows 100% when fully charged, doesn't drop significantly when I unplug the phone, and so far has caused the battery to go down very slowly. In the three and a half hours since coming off charge the battery has gone down to 93%, while holding up to my wife using it for calls and ShopSavvy. I intend on doing the instructions below every few months.
In the Evo space there are two sets of directions on how to prep your batteries for a good charge. One involves plugging and unplugging your phone while at full charge, and the other involves briefly turning your phone on and off between charges. Because I'm impatient I've amalgamated the two with success.
Fully charge the battery with the phone on (several hours)
Once the charging light is blue, unplug the charger
Turn the phone off, then plug the charger back in, for 30-60 minutes
Unplug the charger, turn the phone on for two minutes, then turn it off.
Plug the charger back in for 30-60 minutes
Then repeat this cycle about ten times: unplug the phone for five seconds, then plug it back in until it says it is at 100% (about two minutes)
For the record, I think this has little to do with the battery and a lot to do with how the phone recognizes the battery as full.
I haven't had any of these problems. My battery charges %100 with blue light and it doesn't drop after I unplug it either. Guess I'm lucky

I don't run a battery app. When the blue light comes on it's done. I get about 11-12hours before I get the low battery warning.
Ha! It really worked. She's at 17% and its been 1 day and 11 hours. Not as good as my Evo.
I guess I'll re-try calibrating the battery again, first time I tried it my battery ended up at 95% instead of the regular 98%, really odd.

That seems a little crazy. All you should really need to do is drain it until it won't power on anymore (not even for a second) then charge to 100%.
Still, the epic's sensor just isn't very accurate at the top-end (most aren't), so you're gonna get some strange behavior near the 100%.
All the older WM phones were weird like that too in the 90% range; the sensor just can't detect it very accurately near full charge. The difference was that they showed battery in 10% increments, instead of 1% (unless you use a hacked driver).
too crazy for me.
I think I'm going to just buy some spare batteries for this phone. Immediate unplugging leads to 100% battery.

I have the same problem, I'm using battery life and juiceplotter and they give me the same %

Thanks for this. I was having trouble getting my device to recognize the top 3% of the battery, and one iteration of your plan above did the trick.
^After I noticed these steps in the Evo thread last week, following them did the trick for 1 iteration.
My phone rarely has stayed long @ 100% after coming off a full charge since then, though.
My N7 has been on charge for 4 hours (charging while turn-off). Just took a look at it and it says fully charged but only 97% (see in setting > battery). Once I unplugged and then plug it, it show 100% fully charged right away. This is my second charge since I got it and the first one was also like this.
What happen to my N7's battery? Any idea how can I make my N7 fully charged at the first charge. Thanks!!
