If you want to avoid this from happening, after your phone is charged, simply turn it off (while still connected to the charger). You'll notice it'll continue charging once again for another 15 minutes or so.
Once this is done, the first 10% of the charge will not drop off quickly anymore. It appears HTC did this by design.
This is a well discussed issue. The last 10 pct can only be charged by turning off ur phone, remove the power for 5 seconds replace power plug. It will charge for about 30 min. Rinse wash repeat 2 more times. Power on. Then ur first 10pct will last a long time.
the batteries always odd for the intitial use IMO. they seem to be more consistent after a bit. are you leaving it on the charger longer than when the light just turns green
and i dont agree that the ONLY way to charge the last 10% is with it off. i dont turn it off and it act the same no matter what.

Try this before charging the phone open up the desk clock app and then connect the charger, for some reason the battery is not fully charged no matter if you leave it 2-3hrs after the light is green, for example my phone was charging overnight and the light has been green since I got up this morning, then I read about the charging tip and unplugged it ( opened up the desktop clock app) re connected and to my surprise its still charging the light is make to orange ( its been 45mins) so that proofs that the reason the battery drops the 10% fast is because its not completely charged even when leaving it overnight.. I take no credit for this here is the link (NEW) battery trick!!! 6/5/10

You no longer have to do this method to get it fully charged

I plugged in my phone at 60% battery life after opening the desk clock app to see the time, weather and battery % and once it hit 100 and I disconnected from the charger, it immediately dipped to 99%. What did I do wrong?
Step 1: Open desk clock app
Step 2: Hit back key to see time and weather
step 3: plug in charger
step 4: no difference

Yes, the first 10% goes by very fast for me. I don't really bother with the battery trick that's been discussed on the boards (the turn off, replug, turn back on); That first 10% doesn't make a big difference for me, although I've never heard of that desktop clock app trick. I may have to give that a try as I don't like constantly turning on and off my phone.
the $5 external charger i just got charges my battery full and the first 10% lasts just as long as the rest. last night it was pegged at 100% for 2 hour and 15 minutes after i charged it with the external charger and then put the battery in my phone and booted it up. it was 2 hours and 15 minutes of idle time, other than me waking the phone to check the battery % cause i was curious, but still that's a long time before it dropped 1%.
I use a case on my phone.. so what a pain it is to have to remove the battery to charge it externally.
I just charge my phone, usually overnight.. and within about 2 minutes of taking it off the charger it's down to 90%. I don't have a landline, so I don't like to have to keep turning it on and off. I usually end up forgetting to turn it back on!
I love the phone, but I'm not a big fan of this battery issue.

i have a case too. the verizon silicon case. it's kind of a pain to get off, but whatever.

ONLY 2 more times? Does more times = bad news or is it just fully charged after 3 cycles?
Dumb question...could this damage the battery at all?

Wait, can you please explain EXACTLY what you are doing for this new battery trick?
This morning, my phone finished charging, I left it on, unplugeed, when to the desk clock and it was at 99%, plug it, and it finished charging in a few seconds.
Then I unplugged, powered off the phone, plugged back in and it charged another 20 minutes or so.
So.....how do you get the phone to charge that extra 20 minutes without actually turning it off?

EXACTLY my observation. I saw this nugget and thought I'd try it, but I followed the directions laid out and it charges only for a couple of minutes. As soon as I turned the phone off (phone was reading 99% when I did) and plugged it in, it remains charging for an additional 30 minutes. Not sure how others are doing this as described without shutting the phone off...
Has anyone tried this "trick" yet to see if, when using this method, then powering the phone off while connected to the charger, is it green or orange? If you have used this method, and charged it until it has turned green, then powered the phone off while connected to the charger, the indicator would be green if this "trick" actually works. If it turns orange again, it did nothing.

i really hope they can fix this issue. it's really a bummer that we have to charge our phones with external battery chargers to truly get a full charge.

I have an observation I've made about doing this "extra charge" where you shut off the phone and charge more.
Seems to me that, if I turn on the phone again, after it's finished the 2nd charge, but still leave it plugged in, it drains down to the point where it was before that 2nd charge.
In other words, I charge with the phone on, unplug, power phone off, charge until it's green, turn on the phone, leave it plugged in for a while, unplug and I drop to 96% pretty quickly.
If I don't turn on the phone again until I take it off, it seems to hold the 100% longer.

Anyone notice this?

I have noticed this the past few mornings and have had to ask WTF?
This whole battery charging thing, we we need some kind of a bizarre conversion chart and multiple techniques, is for the birds. HTC needs to fix this in short order. I can't believe in 2010 we have to trick the phone into charging the battery completely.
If I hadn't purchased the Seidio Innocase II I would go on eBay and buy a cheap wall charger for it so I could have it charged correctly. But, then I'd have to shut it down and take the case and battery door off every day, which I'm not to interested in either, so I'll choose the lesser of two evils and rely on the bizarre conversion chart to charge my battery...

Where is this being "well discussed." I see a lot of other posts referring to battery life but not this specific issue.
Has anyone taken a multi meter to the battery after the initial charge? It shows what is pos/neg on the battery. If not ill check in the morning and see what it says before and after the turn it off and charge again trick. This will tell if its doing anything.

Please post your results.
This sounds like it might provide some interesting data.
I didnt get a chance to do it myself but i did find some info online where someone had already done it. A 3.7 volt lipo battery should be close to 4.2volts when fully charged. . So in essence it shows that its true that the battery light is cumming on at only a 90% charge. Hopefully they can fix this with a software update. I also want to note that if you have the battery out and in a charger it will get a better charge
here are his results.
Measuring the actual voltage at the terminals let's you see the approximate state of the battery's remaining charge, using the rule of thumb guide (for Lithium Cobalt Polymer chemistry):
4.2 volts 100%
4.1 about 90%
4.0 about 80%
3.9 about 60%
3.8 about 40%
3.7 about 20%
3.6 empty
Full Discharge State: 3.55V // 3.52V // 3.51V
After30 mins of AC charger: 3.82V // 3.80V // 3.79V
After 60 mins of AC charger: 3.96V // 3.95V // 3.93V
After 90 mins of AC charger: 4.15V // 4.13V // 4.11V
After 160 mins of AC charger: 4.16V // 4.14V // 4.12V green light comes on
After 180 mins of AC charger: 4.18V // 4.16V // 4.14V
also Here is the thread if anyone wants to take a peak.

Well, I don't think that data is very helpful unless we know what the readings are when tested after green light comes on power phone down green light comes on again.
When the charge started it was at 4% on the phone. When it said a 100% is when it was at 4.16. Then turning off the phone and charging more is when it goes to 4.18v. at a 100% charge.
I will do my own test tonight if i can kill the phone. That shouldnt be a problem since i just got it thursday. Ill update with a new thread.

please dont, we dont need more battery threads...plenty of others to post your results in and compare to others that have given their results in the threads
sorry should have been reply not new thread. I know there is way to many battery threads as it is. I'm just trying to bring some understanding to what we are getting. Hopefully to end these threads. Its a small battery in a powerfull phone. Its just the short end of the stick we got and have to deal with it.
Does the first 10% of the battery drain quicker than the rest
