I have now done three cycles now drained to 1% and put on charge over night when I unplug and check the phone it says 98% and drops 2-3% within 5 mins of use. But if I plug it back in it will then go back to 100%. Anyone else?

There have been threads about this already. Batteries, once charged fully, cannot 'keep charging', so they will stop charging until it is low enough to charge again.
This protects the battery from all sorts of nasty and evil things.
^ precisely. Batteries shouldn't be pegged at 100% and continue to be charged. The firmware lets it drain down then charge up again. You can just get 'unlucky' and unplug at a point where its discharging and at 98%.
I remember that happening with the Nexus S. I'm thinking it must be a Samsung thing. It's just one of those weird OEM things like, Motorola phones measuring the battery in 10% intervals.
All manufacturers charge their batteries this way but there are many ways to mask that process. People apparently want to see a fully charged phone when they plug it off the charger. They don't mind that their phone drops to something between 95% and 100% in a matter of minutes as long as it's "full" upon disconneting. Seems Google just displays the correct charge instead of pretending to be on 100%.

Pretty much. The G2 with stock firmware (and from what I remember with the Evo 4G w/ stock), HTC charges to 100%, discharges back to 90%, and charges back up again. etc.. The LED charge indicator turns green at 90% (so according to them, anything about 90% is a "full charge").
You can see this in regular use. There are days where my phone sits at 100% for hours, and others where it only takes an hour to tick down do 99%, even with the same usage. Just depends what "state" the battery is at when you pull it off charge in the morning.

Hi every one,
As far i know, there is a BUG on every official ROM for European GSM Touch Pro2.
When your battery get full charged and keeping it plugged to the wallcharger, then your Pro2 start taking the power from your battery and NOT from the charger.
This can be checked by yourself and you will see that even with it connected, the battery in running down charge, till you unplug it and plug it again after some minutes/seconds.
Yeah, I have noticed it as well. Anyone have a solution?
Not a bug. LiPoly's do not like being trickle charged, therefore the charger turns off.
I have not verified it on the TP2 but I suspect that if you let it sit long enough the battery level would drop to some level and the charger would charge it back to 100%.
This is a rather good new if it can manage battery loads cycles...

just thought i would add this
for some reason on saturday i charged my phone via usb/pc and it lasted less than 24 hrs
so on sunday i drained it and charged it vis the plug
its still going noe
72 hrs 23 mins in stanby 30 mins talk and 4 hrs 7 mins use since 17.43 on 18/10/09
is never been this good so i thought it may be the new rom

Lithium-ion
(Li-ion)
Do charge the battery often. The battery lasts longer with partial rather than full discharges.
Do not use if pack gets hot during charge. Check also charger.
Charge methods: Constant voltage to 4.20V/cell (typical). No trickle-charge when full. Li-ion may remain in the charger (no memory). Battery must remain cool. No fast-charge possible.
Rapid charge = 3h
also i have read some where on xda that once it reaches 100% it'll stop charging

Every one is talking about battery and it's components but no one speaks about that with charger pluged in, it should supply power and by pass the battery once it is fully charged like others models do.

hello anyone know about the issue with the battery ok when i charge my euro tp2 all night and when i go to start>settings>all settings>system>power i then click on the infomation tab and under last full charge i get "not applicable" and get 0 hours and 0minute for the rest
im running the offical htc 6.5 rom
To me this sounds CRAZY. So people are saying that when the device is fully charged it starts to use its battery, thats just crazy... So basically charging it overnight leaves you with "almost" full battery in the morning...
I havent noticed anything out of the ordinary, and every morning when I come and take my device from the charger the charging light is green (opposed to the orange when started charging) and the battery shows to be 100% full.
I will check this again in the morning as I havent really paid 10000% attention to it, but I think I would have noticed the weird behaviour…
noticed this since day 1. my dash didnt do this. i did notice that a soft reset will resume the charge.
This is normal behavior for battery powered devices.
When it's plugged in, the charge circuit charges the battery.
The device itself always runs off the battery when it's available, this is why some devices won't power on without the battery installed, and many devices won't power on with a failed battery installed.
Laptops do the same thing, though they can switch to AC only without losing their state.
It's a holdover I think from when electronics couldn't switch between power sources fast enough to not lose anything (I remember the original game boy would reset no matter what if you tried to switch between batt and AC). It's possible that cell phones can't make this transition since there isn't really extra space to stuff in the bits that allow this (some large-ish caps).
I've also heard that this reduces wear on the electronics, because the voltage is more reliable, but I've never seen that documented.

I don't think this is true for (modern) laptops. All the macbooks and thinkpads that I've owned had a feature that if you plug it in while the battery is above X% (usually around 96) it will not charge. It even gives a message saying "Not Charging" in the battery status. The battery percentage then stays constant no matter how long I use the laptop, so it is not DIScharging either. Therefore it must be running from AC. If it can do that, I doubt they would have it run off the battery as soon as it is charged to 100% on a full charge cycle. I think any time AC is plugged in, a modern laptop will run from AC rather than battery, regardless of whether it is currently charging the battery. However, that's just my theory from personal observations.
I'm not sure if this has been posted yet, but when I unplug my phone after charging it overnight, it gets to 90% or so in around 30 minutes without use, and goes down at a fast rate throughout the day. If I charge it and unplug it exactly when it hits 100%, I can use the phone fairly regularly and it will take around 2 hours to get down to 90%, and depletes from there very slowly. What's the reason for this, and is there any way I can get the same battery life when leaving the phone overnight?
Running CM7 with incredikernel, although my phone has been this way with countless ROMs and kernels.

Short answer: Yes, you will see better battery life, and no there is not really any foolproof way to make it work if you leave it on the charger after it hits 100%.
Long answer: The Incredible has a battery saver feature built in that prevents over charging by cutting off charge to the battery when it hits 100% (actually 96% according to the people who figured all this out and are way smarter than I am) and doesn't let it start to recharge until it hits 80%. The reason, when you take it off in the morning, it drops so fast is because it is no longer actually at 100%, but has dropped to a legitimate ~90% since having hit the "100%" threshold.
There are some kernels out there that do allow "trickle charging" meaning they keep the phone at a legit 100%, but I don't think many have seen much success using them with the Incredible.
I get around this by charging a bit at night (using anywhere between 80-100%), leaving it off the charger until morning (I usually drop only around 4-5% per 8 hour night) and plug it back in while I get ready and eat breakfast. This usually puts me around 95-100% depending how much I was able to charge the night before and seems to be a much more simple way to handle it than bump charging in my opinion.

I've seen similar topics regarding the quick drop from 100 to 90%, but the battery life as a whole seems to be much longer when it's taken off the charger immediately after it hits 100%. There's so many topics on here, I can't find exactly what I'm talking about, so it's difficult to judge. I'll definitely try the tip in the second post though. Thanks!
It will charge it up to 100% but it won't stay there if you keep it in. It'll let the phone die down to 90% then it'll keep it at that level.
So yes if you unplug it when it first hits 100% you will have a full 100% battery. If you let it sit for much longer than it'll be at 90%
It's been said that leaving it on charger for a while after fully charged messes with the battery meter.
I always bump charge. Charge it full while on then power off and charge till green lights on. Def gets me more batt life. Im getting 24+ hours on a single charge under normal usage with UD 3.1.1.

Yeah fair statement, I had thought about that. I wasn't sure if it was bad to say plug the phone in at 11pm until 7am (8 hours) charging whilst it being turned on? I assumed if it was going to be plugged in say for that long that you should turn it off.
I just plug it in - went to bed on 80% last night but fair enough I'd hardly used the phone all day (standby battery life is incredible)

So you stuck it on charge just to boost that extra 20% yeah? How come you didn't just leave it until it was low?
Should of asked if people would partially charge it or if they always ensure its fully charged.. Can't amend the poll now though.
I was thinking about trying that - might do that tonight and see how it lasts...

Where did you hear that? Mines dropped to 14% before and I then turned it off and charged it and the battery still seems fine. Wasn't aware you could damage the battery if it got too low...
I killed my battery first 2 charges - never have in the past but thought I would this time
I have always charged with the phone on, all my phones since way back having an analogue Nokia mobile and never had any battery issues. Only time I have ever switched my phones off is if I was getting on a plane or the battery got really low and didn't want it to go completely flat.
Just plug it in whenever. Modern li-poly batteries doesn't have memory and charge cycle life is based on full charges.
Part charges actually increase life due to low % cycling

Agreed.
One thing to note is that you should never let it completely drain the battery, the phone will switch itself off once the battery reaches critical level then it needs a charge. I'd recommend charging it when it reaches 5-15%.
Also I'd never leave it charging over night it interrupts the cycle, if I have to charge it over night I set an alarm to go of after a few hours and unplug it.
i have 3 or 4 charges from different makes-and only htc charges the quickest. the worst is usb cable and car charger. but due to usage i need to charge twice a day

You are 100% right most modern phone battery’s don’t have memory any more so no need to worry about it, and no need to do full discharge and recharge cycles to maintain battery health, and if they do they normally tell you in warning labels or in instruction manuals, for example I recently bought a new shaver and it tells you to do a full discharge and then leave it on charge for at least 12 hours every 3 months to maintain battery life.

batteries have safety features built in so don't worry. What for you looks like 0-1% left - what android is showing you, might be actually 10-20% as seen internally by the battery.
Also, I have completely discharged my phone once, I simply left it at 1% and waited until it shut off. Then I charged to 100%. From then on, I charge whenever I want, phone is always ON.

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.

that happened top me on my first charge
just give it a couple charges it will start going to 100
I have to say battery life is great for me on pixel 2 xl. every time i charge it will go all the way to 100 %.
Hmm, I've charged it overnight for awhile now and it still won't get to 100%. It'll say that it's fully charged but will just show 98%
Experienced the same thing on my Pixel 2 XL. I did manage to fix it by powering the phone off for 10mins with it plugged in/charging. Once rebooted it showed 100%. Otherwise it will stay at 98 or 99% forever...
Strange thing happened yesterday. It finally charged to 100% and 5 minutes later I unlock the phone and its back down to 99% while still plugged in to the OEM wall charger (showing charging rapidly).
Copy and paste from my post in the Real Life Review section:
I would leave my 2 XL charging overnight (stock charger and cable) and when I wake up around 7-8 hours later, the percentage would either be 97%, 98%, or 99%. I've rarely seen my phone go to 100% since getting it on the 18th.
Whenever the battery hits 50% and I go and charge it mid-day, it would take a painfully long time to charge up after around the 85% mark (the general consensus and expected). I would check and it would be at 99%. After around 10 minutes, I check again and it shows 98%.
Needless to say, I disabled "show battery percentage". If the battery icon is full, then it's 100% to me.
I have this with my 2 xl too. It'll stop at 98-99, and if I unplug/plug back in a few times or reboot a few times it'll eventually get to 100. But it'll drop from 100 only after a few minutes even unused. Not sure if by design or a minor hardware issue.
Mine was charging overnight to 100% now for the last 2 or 3 days it's only been going to 98% overnight. Battery life is still good though.
I was wondering of was something to do with Battery Stats, maybe needs cache cleared or resetting somehow.
Actually I cannot even get mine to charge to 100%

Actually I cannot get mine to charge to 100 percent except two charges ago. That being said there must be something wrong as using the white charger and cable to go from 2% - 98% it took more than 5 hours ! I cannot get it to go past 99 % and I have been charging with phone off then with on and then according to Google support tried safemode but still no difference. Highly frustrating for a $1k phone. I finally shut phone off for the last 20 minutes and then checked the charge and it is now at 100% but what a battle and a SLOW SLOW charging phone.
I never charge mine to 100%, I usually take it off the charger around 85%. Not had any battery problems, don't think it's ever necessary to hit 100%.
I've had the opposite. Wake up it's 100. Listen to music on the way to work for about an hour (bluetooth). When I get there it is still 100 percent. Put it in pocket for another hour, check phone, 96%.
I turned off my phone when plugging it in last night hoping to make this go away.
When I turned it back on this morning... still only 98%...
