The phone should not overcharge the battery, lipoly batteries or rather the charging mechanism shuts down when it reaches capacity. They do not trickle charge. Lipoly batteries take approximately 1hr-1hr30 to charge, after that the charging circuit switches on and off as it drops a few percent.
Most lipoly phones 'lie' about when they are full so people dont get concerned as they appear to drain whilst still plugged in. They could infact still register 100% even when they are at 90%!
In the last stage of charging they can get warm. Even though the guage states charged it may still be finishing the last 'virtual' 10%. After 10 mins the battery should cool down, if it doesnt then there could be a fault.
Overcharging lipoly using unconventional techniques will lead to explosive consequencies.

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...

It will definitely decrease the life of your battery..
It wont harm the phone as a one off every now and again. Lipoly batteries charge in about 1-2 hours and dont trickle charge. Once charged the phone switches off the charging circuit, when it drops a few percent it begins charging again. Lipoly batteries have a limited number of charge cycles (usually in the region of 500) before the capacity is reduced, if you charge once every day then you get a good year and a bit out of the battery.
The more charging the battery receives the less life it has. If you charge a few times a day then the life could be as little as 6-9 months before it degrades. The process is gradual though and not like a cliff edge, however, as the battery capacity is reduced there is a greater likelihood that it will loose charge quicker and switch the charging circuit more often causing further reductions.
Best practise is to charge once a day until it registers as charged, then leave it ten minutes and unplug it. I always reboot my phone once a day after charging to ensure that any rogue programs have shut down and therefore not causing any drain.
Lipoly batteries last longer when they are holding a charge. Try not to fully* discharge them too often.
*Never ever 'fully' empty the battery, you shouldnt even be able to as it should shut down the phone to prevent damage. (When the phone reads 0% it is still holding nearly 2/3 its charge!) A discharged lipoly battery has a safety cut out to prevent usage when severely discharged as they will explode.

I charge mine whenever the battery drops below 10-20%. So far the battery life is same. Phone is about 6 months old.

When I charge my phone it only charges to 99%. I'll leave it in for a while, come back and it's only at 99%. Either charging in the wall, or on the computer. It used to make it to 100% then all of a sudden it just stays at 99% regardless how long it charges. So the charging light always stays on and never lets me know when it's fully charged.
Any idea why?
Thanks.
Mine does that too once in a while, randomly.
But the Sensation would do that to randomly.
Dunno why.
Battery is strange...
I get that too. But eventually it will get to 100%. There has been times where it was charged to 100% then suddenly drop to 99% even though it still plugged in.
Did you get your phone recently? I'm thinking its because the battery needs to be conditioned.
Mines always does that, as soon as I unplug it it jumps to 98%. Im hoping ARHD fixes this
I've installed Battery Widget (from Market) and it reports 100%. I plug in every night and in the morning it reads 100%.

New Amaze Android Revolution HD ROM by mike1986?
This happens with many devices. I have not seen this yet on my Amaze but I am sure at some point it will happen. Try turning the phone off and charging it to 100% then power it on also try running the battery all the way down and letting it charge to full UNINTERRUPTED over night. If those dont help you can always try another rom with better battery management or go into a t-mobile store and get a battery replacement if your battery is still under warranty. Hope this helps
HTC does this on a lot of phones. It is a safety default to keep the battery healthy and safe. I had this issue with the Evo. The only way to fully charge a battery is to have other a wall charger or a SBC kernel.
its the best sense rom known to man in my opinion.

My stock battery is 3.8v, and it only goes to 100% if I charge it in the phone. If I use my wall charger, it shows up at 99% when I put it back in my phone. I have two aftermarket batteries that show about 98% when charged from the wall. I am thinking that the phone charging circuit is set for 3.8v, and might possibly overheat the aftermarket batteries (3.7v). I saw one review that said these batteries melted the top of his SIM card. I'm not planning on trying that; I use the stock, charging every night, and swap the spares in if I run out of charge during the day.
I just remember hearing the same stories when I had my evo. You could charge for hours and unplug it and it would almost immediately drop to 99 or 98. So my previous statement may or may not help.
I charged mine over nite and woke up to it being 99%, left it for another hour or two and it hit 100%. I would say to leave it a little longer to get that last 1%.

I find that if my phone its powered off while charging, it shows 100. If powered on, it shoes 99.
Sent from my Dell Streak 7 using xda premium
this is normal for lithium ion batteries...it also depends how the manufacturer perceives the battery...some manufeacturers say that your phone is 100 percent but it might only be around 95-98...overcharging lithium ions are bad...also some manufacturers say you have 10 percent left while you might actually have 15 or maybe to percent left...this is a fail safe method to shut off the phone and keep the battery from draining completely WHICH IS REALLY REALLY BAD FOR LITHIUM IONS...OVER CHARGING THE BATTERY IS BAD TOO...perhaps htc's thresh holds are a little different and actual to the real battery life.
also not a good idea to use your phone or any lithium ion device while its charging
powering off your phone to charge it overnight is the best idea to give you lithium ion a long life but this is not practical. this is why it says 100 percent when you turn off the phone and 99 when you're phone is off....it confuses the phone: " A portable device must be turned off during charge. This allows the battery to reach the set threshold voltage unhindered, and enables terminating charge on low current. A parasitic load (which means using phone or turning screen on while its charging) confuses the charger by depressing the battery voltage and preventing the current in the saturation stage to drop low. A battery may be fully charged, but the prevailing conditions prompt a continued charge. This causes undue battery stress and compromises safety."

Since Sunday my Aria has started heating up weirdly. When charging and while using, there is tremendous heating in the area right behind the optical touchpad.
Also the battery is not charging properly and discharging quickly.
I first thought it may be a battery problem, but wanted some genuine views regarding this.
Will changing my battery remove this issue? Has anyone faced anything similar?
There will always be heat around the touchpad whenever you are charging while using it. Happens to me all the time at least. Unless your battery exceeded 45 degrees Celsius, then that's abnormal.
You can track your battery stats for example, heat with apps in Market.
You said it discharges awfully quickly. Mind telling me, how long does it take for it to discharge from 100% to below 10%?
Really quickly.
For example, I charged the phone whole night from a wall charger, while switched off.
In the morning, I turn on the phone, it shows me 19% battery. I rebooted: 8%. Rebooted again: 2%. This all happened in about 5 minutes after taking the phone off the charger.
The phone used the 2% battery for about 15 minutes on standby, with no internet, before dying.
Now it does not even turn on. The battery is definitely gone, since it has bulged a bit. But I want to be sure before buying a new battery, if the new battery will face the same fate or not.
For now, I have given the phone to my brother who will test the battery in his phone. Let's see.
There's definitely a problem with the battery. It is advised you do not charge a faulty battery. It may damage your device or worse, explode depending on what the fault may be.

New battery should fix the problem. There's no reason to suspect that the phone is causing the problem.

Perform shallow discharges.
Instead of discharging to 0% all the time, lithium-ion batteries do best when you discharge them for a little bit, then charge them for a little bit. The table below, from Battery University, shows that discharges to 50% are better for your battery's long-term life than, say, small discharges to 90% or large discharges to 0% (since the 50% discharges provide the best number of cycles-to-usage ratio).
Don't leave it fully charged.
Similarly, lithium-ion batteries don't need to be charged all the way to 100%. In fact, they'd prefer not to be—so the 40%-80% rule you heard is a good guideline. If you do charge it to 100%, don't leave it plugged in. This is something most of us do, but it's another thing that will degrade your battery's health.
Fully discharge it once a month.
This may seem contradictory, but hear us out. While lithium-ion batteries shouldn't be discharged regularly, most modern batteries are what's known as "smart batteries". This feature can get miscalibrated after a lot of shallow discharges. So, manufacturers recommend fully discharging your battery once a month to make sure this stays accurate.

The only big no no is to constantly discharge to below 5% and recharge . That according to the experts leads to a much shorter battery life .
Yes leaving on charge is a waste .
Wiping Battery stats does not improve battery life .
But all this is an old story posted time and again and bring nothing new .

there is a built in feature that stops charging once battery level reaches 100%. so there will be no harm to your battery. I have doing the same since gs1
My old Nokia 3510 needed a battery replacement after 4-5 years since it only held 3 days worth of charge instead of the usual 7-8.
I constantly let it discharge from 100% (overnight charging) to empty, the replacement battery cost me 5 bucks.
My Galaxy S1's battery has, after 2 years, no observable loss in capacity with overnight charging to 100% and dropping to 10-15% over 1-2 days.
A replacement battery would cost roughly 15 bucks.
I could go on the same about my Laptop, Netbook, Tablet and other devices with rechargeable Li-Ion batteries.
The point is; don't try to forcefully extend your battery life, enjoy your phone. Most people replace the phone every 1-2 years and the batteries are designed to live that long with high usage and deep-discharging. If yours should not or you plan to keep the phone longer, a replacement battery is cheap.

All Lithium batteries have it (and need it) since there is a risk of damage, fire or even explosion when it is overcharged. That's why not the phone but the battery itself has the corresponding controller. Since the controller cannot measure the exact capacity of the battery (only an estimate), it is recomended to deep-discharge and fully charge (charge-cycle) the battery once in a while to reset the controller's counter.
Battery replacement is cheap and easy as abc. That's the benefit of having removable battery. Just enjoy your phone.
