No issues with battery here.
My advice would be to completely drain the battery.
Keep powering the device on until there is absolutely no juice left.
Then remove the battery, re-insert and leave to fully charge without powering the device on.
See if that resolves your issues.
Battery life on mine is excellent after a weeks useage, no complaints here.

Have you tried this yourself? Because, I wouldn't probably be comfortable draining the battery quite as empty as suggested by this method. The Li-Ion batteries need some charge to be left in them even when they are "completely" discharged, or else they are damaged (it may actually stop accepting charge, so recharging becomes impossible).
I think it should be enough to just leave the device on for as long time as possible - until the device finally shuts itself down. Then do a full recharge and you should be ready to go.
Of course if you've done this yourself and can confirm the battery still accepts charge after such procedure, then no serious damage has presumably been done. Wouldn't go quite this far myself, though.
Cheers
I can't say for certain about the TP2 battery but most Li-Ion batteries will have a tiny protection circuit in them to prevent over charging and over discharging. Becasue of the potentially explosive nature of Li-Ion batteries I would be very suprised if the TP2 battery didn't have any protection.
Yes that's true. And TP2 most certainly has this chip. However, I'm not 100 % sure if that chip can protect the battery against this kind of "abuse". It probably can, but I wouldn't like to be the first in line to check if it can or not...
I agree with what you all say, and yes I'm pretty sure that the protection circuits are there. I haven't tried it on my Rhodium, but did on my Raphael after lending to a colleague who was incapable of maintaining. Charge would hold for around three to four hours of useage, pretty damn useless after a week of abuse.
I totally disharged as much as I could, then left overnight with the device powered off and since then the battery useage has been as norm.
I know were not supposed to be affected by memory issues, but go figure...........

did as you said drained it right down even powering on again to make sure
gave it a full charge while powered off
from 5 this morning it has been in stand by and has about an hours use and im down to 2 bars on the main screen
when fully charged i check the power in setting and the last green bar was not lit
nothing running in the background
any other ides to try to sort it before i contact MPD and see about getting a new battery
thanks again for the help

Nope,
Sorry mate, sounds like your battery is a dead one.
Cheers,

been in touch with HTC uk
they have told me to do the following
from flat
charge for 10mins then use the phone do this 3 times each time making it dead before recharging
thay say this will condition the battery
does this sound right?
so what is the best thing to do?
is there any way of charging,dis charging ect to get the best battery life?
or should i just charg it to 100% and use it right away?
i did a charging squence with my nexus s. but duno about the Gn.
for me is to turn on the device and start working until the battery drops to 0-1%.
only then im charging it X2 then needed to go to 100%, you can make it Double if you want.
Well, this is going to be one of those threads where everyone has their own little way to care for a battery and others say their way is better, etc, etc the arguments breaking out which will result in people posting www.batteryuniversity.com in an effort to win said arguments.
Here's mine. On a brand new phone, I put the battery in, boot up, connect the charger, run it to 100%, disconnect charge, run battery all the way down, connect the charge, run to 100% and go about my life charging when I need to.
My two cents. Have no idea if it does any good, but my SGSII is going on 1 day 14 hrs on a single charge, so it must work somehow...

My way,
Turn on phone, charge it to 100%, leave it plugged for an extra 20 min, and start using it normally.
The only time I discharge a battery is after a couple of months. Because we never charge it to 100% and they start creating memory and charging less and less every time. The purpose of discharging it completely is to erase its memory. That's why when it is new, I see no point on discharging it completely. Batteries suffer every time they are completely discharged and if they are left 100% for a long period of time, thats why new batteries always come charged about 50%, to extend battery life since they may be stored for a long period of time. (ref. aviation school)
Just my 2 cents.

That hasn't been true since NiCd's in the 1980s.
Modern Lithium-Ion and Lithium-Polymer batteries have no "memory" and are actively damaged if allowed to discharge fully.

OK, I may be wrong I'm no expert.
Why do people keep discharging them to 0% if they have no memory? (I'm not been sarcastic)

Generally because they don't know any better and they don't realise battery technology has moved on.
Because batteries "back in the days" were quite sensitive to memory. That's why we were all raised by the complete-discharge-mantra, which sticks with you forever. The next generation won't have this problem and will feel free to charge their phones when they want to. ;-)

Becouse android in itself keeps a battery log, it is from this log your device calculates the amount of battery you have left. To keep these values true (calibrated) you should do 2-3 cycles where you on purchase, discharge fully until device auto shut down, start it WITHOUT charge a couple of times and let it die to set the min value, charge up to 100%, use your device again till auto shut down... you dont have to worry about damaging your battery in this case since your device it programmed to shut down with good marginal of battery depletion. What you SHOULD NOT do is leave an empty battery uncharged for a long period of time.

Lithium batteries will be damaged if they are stored fully charged or fully discharged for extended periods of time. Thats why the battery is about half charged when its new. They have no memory effect, they just loose capacity.

Good point. While it's important not to fully discharge the battery too often, there is also the issue of calibrating the battery meter.

That's exactly what I do, had 14 hours of moderate use today and still had 45% left. More than happy with that. It seems to be getting better each day at the moment.

78% after 14 hours here, but that's light use.

The whole "discharging the battery fully" thing doesn't really apply here - because nobody will ever fully discharge it. The Nexus uses a Lithium Ion cell - it's a single cell, with a nominal voltage of 3.6V. When fully charged, it peaks at 4.2V (at which point, the charging circuitry cuts off to avoid overcharging). However, when we "fully discharge" our phones, the cell only goes as low as 3.5V - and then the phone shuts off.
In reality, lithium cells can discharge to around 3.0V before any damage occurs. However, this would yield very little extra battery life. Stopping at 3.5V provides a wide safety margin (lithium cells are potentially dangerous if overcharged/discharged), whilst extending cell life.
In a nutshell - don't worry about running your phone down to 0% (unless you're putting it in storage, in which case leave it at about 60%). In fact, it's a good thing with a new phone, as cycling (charging and discharging a cell) helps to "wake" the cell up and reach it's max capacity more quickly.

i see some good ideas about charging and discharging.
but it is indeed a fact that 100% and 0%(real) isnt good for our new race of battery's.
but a few posts here already tell how and what.
and its not gonna be a thread of arguments and stuff,if we all keep it in our heads that we just want to share our tip's of how you think its the best way(and have some experience with it)
just to share some info. and not compete the info against each other.
i well know there are different ways. but its always nice to read what experience people have with it to make a choice for my own and any other wanting to know this.
and i posted here in the GN section,instead of the Android section because each phone handles battery different,and this narrows the options down to a single device :3
Just keep in mind it's not just about the battery itself it's about the software registering how much actual power the battery has at a certain time, so if the battery has in actuality 100% charge in it, and the software reads 80 then your phone will die out sooner. So charging and discharging is good because it calibrates the hardware with the software. Just remember to switch off the device then charge it so the software doesn't auto discharge when it thinks the battery reached 100%.
K i just skipped thru the posts, gonna throw in my input real quick.
Basically just run down the battery. Once it turns off, hold the power button to make sure all the juice is gone. Then charge it up to 100% and leave it there for a good hour. Now (root required) download https://market.android.com/details?...yLDEsImNvbS5uZW1hLmJhdHRlcnljYWxpYnJhdGlvbiJd and follow the instructions .. its not exactly necessary but a nice thing "just in case" .
thats my plan anyways.

Where does the loosed capacity go? Can it be caught?
And what do you think about charging with the phone being switched on? Is it better to have it switched off?

Won't make a difference.. Phones are designed to be left on anyway.
So, I bought another battery. Will this sort it?
Also, what's the usual procedure?
Should I charge the battery to full in the phone (turned off) then boot, set up, then charge again and reset battery stats?
The problem is that the battery control chip doesn't take into account that the battery ages.
Resetting battery stats or charging while turned off will only clear the stats you see in the settings menu. This guide will make your battery drain to 0% again: http://forum.xda-developers.com/showthread.php?t=1534892
I don't know what a new battery will do though.
I gathered that, but as the phone is going to a new user (my stepson) we got him a new battery anyway
I just wondered what the correct procedure is. I know you need to do a first charge with a new battery, as with a new phone, however, this phone obviously has a working ROM already on it.
So, the phone is charging now, switched off. Should I turn it on, use a little, then use the battery calibration app to delete the stats and then drain to 0%?

Well, that assumption is probably inherited from the NiHM batteries in the past, because it's not needed with Li-Ion batteries. In fact charging to 80% is better than charging to 100% and keeping it plugged in.
You can read more about it here and here.

Just charge it and use it for a full cycle. If it shuts down at 15%, you can try the battery calibration from the thread I mentioned above. If it doesn't, you're battery capacity is the same as the one the battery chip has calculated, which is good.
So, why does the first charge take so long?
This thing is still charging and it's been on the charger for 3 hours, whereas usually it'd be charged fully by now.
Been like that for every Li-Ion battery I've ever had (including my S3, took around 6 hours to charge, usually takes 3).
EDIT:
Just to clarify, I don't intend on leaving it past the green light. As soon as it says it's full I'll be taking it off charge and not trying ot overcharge it. But I still have the orange charging light after 3-4 hours.
To be honest, I don't know. Maybe it's a safety to prevent overcharging. Coincidentally, I've got exactly the same issue now. I asked about it in the calibration thread. I suppose it's normal, but I'm not sure about that.

The first month this phone was great on battery... Its horrible now 3 months later! I shut off all the samsung stuff that suck up the battery. I have the screen power down to the lowest setting. Sometimes when i charge the phone is says its fully charged and when i unplug it its about 98%. Does this once and awhile. I've been playing a games for about 1.5 hours. The batter is about 40%. Is this normal?
10 minutes later i just checked the phone and now its down to 30%... wtf is going on with this battery?

1.) You should get Better Battery Stats from the Play Store so you can see what could be causing this battery drain.
2.) When you unplug your device and it shows 98% it's a good thing. It means that your fuel gauge is working correctly. We have a safety feature that helps the battery to never get over charged. It helps the battery last a lot longer. The way these batteries work is if it's constantly overcharged over an certain amount of time it would deplete the battery life.

you have something in the background going on. could be a rouge app. check Better Battery Stats.
A coworker of mine has a Galaxy III on ATT same as I do. She complained about her battery to me. We both opened our Elvision Battery Widget and saw that screen times and time on battery were within 30 minutes of each other (1hr 50m mine vs 2hr 15m hers). She had 73% and I had 95%; her widget said 38XXmv, mine said 4100 (I have more stuff on than her). I had her restart her phone just for the hell of it, then I flipped through her settings and TURNED OFF battery saver. The problem went away. I've never used the battery saver and my battery stays golden all day. That said there's no telling if the restart did more for the phone than turning off the battery saver. I told her to turn on battery saver for 2 hours this weekend and see what it does. Will keep everyone posted.

Stock ICS on my S3
I'm rooted on stock ICS...
Google Now is a huge battery drain from my experience.
I'm rooted stock. No battery issues in fact gs3 has some of the best battery life I've seen second only to my hoxl.
Download autostart fromvthe market.
Find out what's running at os startup.
Disable. Things like googleplay, Googlemaps etc. Don't need to start up.
In fact the only thing required is integral Os components. At start up, I have alimost everything Google disabled.
None of your maps need time start when boot. None of them. Keep in mind I'm talkin aps like ....anything AT&T... w/e you dl'd from market.
Also go through and disable bloatware.
This will help. check your battery. It should be flat or slightly concaved. If it's bulging even slightly get a new one.
Report back and let us know.

I think I overcharged the battery since I had the phone on last Friday. I was used to overcharging my old phone cause it would die in like three hours at the most.. how can I fix it? I want my battery last like 10 hours or so.. battery draining one percent every min while I'm on chrome. I always kill the processes and services so it would fix that. The power saver is no help.

If you are not rooted, you can try letting the battery die and charging the phone fully while keeping the phone off the entire time.
