Has anyone noticed that their 3D drains while it is plugged in? I plug in my phone for charging. It charges completely and the LED turns green. Then it begins a slow drain (as if it weren't plugged in). I notice the behavior on system panel. It shows I have it plugged in, but my charge is slowly going down.
What's going on here? Is this normal?
I read somewhere that once it is fully charged, it stops taking juice till it drops down to 90 percent and draws juice again while still plugged in.
I think this is from the intelligent charging that most new phones have. In fact in every android phone i have had...i put it on charger at night, wake up and it shows full charge, but if i unplug and replug it will drop down to 94ish and start charging again. I believe it is a form of governor to prevent over charging and heating.
Looking at my Battery Monitor Widget information, charging overnight, the battery gets to 100%, then is allowed to drop to about 95%, then charges up to 100%, then drops, then charges, repeating the cycle between 95% to 100% until unplugged. It looks like a saw tooth pattern.

noticed this as well
I love Battery Monitor Widget Pro.
I checked my log file from over night and noticed the same pattern. Goes from 100 to 95 percent. Pretty cool.

seems HTC tweaked it since the EVO 4G, it would drop to 90 not 95. I been using that widget, too, to monitor it.
anyone notice when it starts to cycle back to 100 it stays 99% for a while longer than what would seem normal?

Hi,
Got my 101 yesterday and i charged it directly on the power adapter.
I charged it like 17hours but no blinking led?
It all runs well and i think it is charged enough, anybody got the same issue?

My 70 will only blink if it is turned on while charging, otherwise it won't.
What do you mean, while it is charging or when it is done charging and turned on?
If i charge the 70 when it is turned off, it imediately turns itself on and stays on. When it has fully chrarged the led will flash. However if i put it on charge and it turns itself on, if i then turn it off and leave it charging the led never flashes when it is charged.
Modern Li-Ion battery charge regimes are complex. They will charge until full then turn off until the charge falls below a certain level, then start charging again. So if you happen to look at your device at they wrong time it might not show fully charged because it is part way through the wait cycle. This is done to prolong battery life - it stops the battery from being cooked. You can bump charge a li-on battery to get more juice it it, but that shortens battery life considerably.
Also, it is possible that your battery meter need calibrating. Every 30 days or so let your device run right down before re-charging - this should re-calibrate the meter.
Thanks
I did discover that he only blink when turned on, just what you guys telling here.
Thanks for the reactions

Somewhat same issue, battery charge light NEVER blinked, had Archos 32 for 2 weeks on 2.0.71. The charge would never reach 100%, it would stay at 99% for hours, all day, just could not find that 100% mark and switch to status "charged". When I would wait at 99% for an hour or more, when unplugged, the meter would say 100% immediately after disconnecting it. Maybe it was cycling or doing something battery related, but I doubt it in light of upgrading to fw 2.1.2 and now it charges to 100% without an issue and the power led blinks. Looks like they fixed that bug, or at least it is fixed for me now.
Does anyone have trouble with the Archos 70 not charging at all? This has happened a few times now, I've put it on charge overnight and when I check in the morning the battery is at no charge.
Re: Battery Drain While Charging
Has anyone else experienced this?
This is the first time I've had this happen to me....
Sometimes while charging my phone....I'll leave it idle for maybe an hour, and when I go to check my messages, I notice I've lost 10% of my charge while the phones "charging."

Are you charging using the stock charger? USB cable?
That sure sounds like a bad charger... or you have some kind of hardware short? My phone only loses about 10% in 7-8 hours. I can't imagine it on a phone that is plugged in and charging.
I read somewhere that once the phone reaches 100% it discharges slightly in order to protect the battery. My phone drops down to 95% after it reaches 100% then charges back up to 100% again.

I think it may be a bad charger.....Because if I leave my phone idle on the home charger (It's the oem one) it will eventually lose battery power.
But on a sidenote, I have my phone plugged into my usb right now and it is charging appropriately. But whenever I use the phone to text, or whatnot, it either stays charged at the current percentage, or it slowly loses power (albeit 1-2% every 10 minutes)
I've never had any of these problems before
ive experienced this a couple times. i charge it over night and when i wake up in the morning its at like 96%. when that happens i just unplug it, and plug it back in and eventually charges to full and it stays that way. i dont know why that happens, and it happens sporadically so i can't pinpoint the exact cause

This is the norm for me.
I am experiencing a worse version of this problem... I no matter whether I plug my phone into the wall charger that came in the box, or via usb, it actually loses charge while it is "charging". I have had it completely drain the battery while on charge. I've killed all applications, and the problem still exists. The only way around this is to turn the phone off completely while it is charging- which is something I feel I should not have to do. Not found a solution online yet...

Is anybody having problems fully charging the battery to100 percent? I noticed the battery life has gotten worse since I owned the phone. it would always charge 100 percent. Now it only charges to about 98 percent. I made sure all active apps are turned off and running apps as well turned off. I will turn my phone off at least once a week and fully charge it overnight. I notice after doing this the battery life Is always worse.

Don't believe your battery bar...
Check the number of volts your battery has... its a much better indicator

The phones charges to 100% and then it stops charging if left on the charger. So you will lose 2% or 3% of battery power before it start charging again. This is designed to help keep the battery healthy as its usually not a good idea to leave the phone charging for long periods of time.
I charge mine until the thing on the status bars pops up indicating "full" and then remove from charger. The "full" indicator pops up about a half hour after the phone shows 100% which I find odd however... That also might be a battery health thing as they probably don't want you to charge it to absolute max, so maybe by saying 100% whens its more like 97% that it helps with battery health...

It trickle charges for a while after hitting 100%, then shuts off giving you the "unplug me" notification, drains a few %, then back to trickle charging.
In the morning if you unplug it and then plug it back in it will be fully charged in less than 30 minutes. To the full 100%.
When I first got my phone I was playing with it so much (and testing out the true battery capacity) I was often plugging it in at night with a nearly dead battery - which takes longer to fully charge overnight. So by morning it had only stopped charging an hour or two earlier so it still showed 100% for a while. Lately its been at 60-70% so by morning it has been done for 4-5 hours. So after booting it often shows 98%. No difference in battery capacity, just a longer time post-charge where it has drained a percent or two.

Thanks for all the replies. I guess it makes sense. it just seems to run down a lot faster everytime I turn the phone off and back on the next day. It must just be me

Try the unplug-then-replug routine one morning to restart the charging process. See if it is better that day. If it is, you are probably running into the same problem I talked about in my last paragraph.
I don't know if some of you have the same experience but here is my issue:
I usually charge my phone when I go to bed at night and unplug it in the morning. In the recent a few days, I woke up and found out my GS3 is 99% charged and battery status is still charging after an overnight. I have the Battery Indicator Pro app on it and it keeps the log of all the changes of the battery, so I went to the log and saw that the battery was full charged at e.g. 5:32AM at 100% and CHARGING status, then at 6:15AM it was 99% and CHARGING. So I turned off the phone, and leave it charging when its off and turned it back on after 15 minutes, after a while it showed as FULLY CHARGED at 100% .
I think it was very interesting and would like to know if it's the battery problem or the phone problem, if there is anyone have the same issue.
THANKS!!

I have had that problem before. But now for me it will say fully charged then after i take it off the charger it drops to 98%.

I've had the same problem with taking my phone off the charger and found bump charging helps (remove the phone when at 100%, let it drop and then re-plug it in).
As for not charging to 100%, is there something keeping it awake? background process? Screen not shutting off? Sounds like something is keeping the phone from a sleep cycle.

My friend with a nexus s tells me that his phone fully charges at 96% so it saves that battery from over charging. idk if thats whats happening here.
So I heard that the reason why when you unplug your phone it immediately goes down to 98 or 97% is because the phones are designed to charge as fast as possible. Is there a way to program the phone to slow charge? (like overnight) so that it will get longer/better battery performance?
I am not sure where you heard that.
The reason that you unplug it and it is at 97% is because once the phone charges the battery to 100%, it slows down on the voltage. It lets the battery drain a bit, to about 95% and then trickle charges up to about 99%. It does this cycle until you take it off of the charger. So, you may unplug it at anywhere from ~ 95%-99%.
Well, wolf is probably correct, but I believe it is the charging circuitry in the phone and battery that regulates the charging rate. The charger voltage output will be the same at all times.
What I would like to know is how the charging system works and what aspects can be modified by the kernel.

You can make it charger faster in the kernel, but not too much.

The actual reason is that it's "bouncing" the charge in the background, and due to the way the OS set up to report, you don't see it happening. Li-ion batteries are happiest when they are either charging or discharging. The fastest way to wear one out is to hold it at a single charge for a period of time. To combat that, the kernel lets it get to full charge, and then switches off charging so the phone is operating off of battery for a bit. After it discharges a bit, it switches charging back on and tops it back off. That way, you have a full, or at least a nearly full charge when you unplug, and the battery is kept in a constant state of charge or discharge so it doesn't wear out as fast. The OS plays a little psychology with the user. Most users are going to expect that the battery should be fully charged when they unplug it, so once it hits 100% the first time, it no longer displays the actual percentage...it just keeps displaying 100%. After it's unplugged, it rapidly (over the course of a few minutes) scales down to the actual number before it's starts showing the real number. That makes people think it's starting at 100%, and it lets the battery longevity be maximized.
There are certain battery monitor apps that let you actually see the bouncing effect. The one build into Android Tuner is one.
Thanks for the info everyone!
