[Q] Charge drops overnight on AC?! - Desire Q&A, Help & Troubleshooting

Hey all,
Got a quick question about the charge level on my Desire after upgrading to Froyo. Basically before I used to put it on charge when I went to bed at say 11pm, and it would charge steadily to 100% and stay there until I took it off charge the next morning.
Now, since using unrEVOked and putting stock Froyo on, my battery will charge to 100%, then drop to around 89% and recharge again. It does this once every 3-4 hours it seems. I've done the whole charge til green, unplug, charge til green, power cycle and charge til green procedure and also wiped the battery stats in Clockwork.
At first I thought we'd had a couple of power cuts during the night, but it's every night and JuicePlotter shows an AC charge present all night.
Can anyone suggest what might be going on here?
JuicePlotter grab is attached to illustrate the problem.
Thanks in advance,
Nathan.

This is normal behaviour.
The phone has a safety feature that wont charge the battery when its full.

Ah, ok tahnks for that. Is this a feature of Froyo as it never used to do it on 2.1?
Sods law that it seems to just drop to 90% or so about 30mins before I am due to get up, then takes another hour or so to get back to 100% Maybe I need to sleep longer...or less

if you charge you device while off, it dosent follow the same 100% -> 90% -> 100% cycle, it will charge and stay charged

HD7 never charges 100%

I have purchesed HD7 4 days ago. It never charges 100% even if i leave it on charge for whole night.
Any solution.
how do you know it doesn't? the battery icon isn't exactly specific? but if it doesn't, take it back to the store you bought it from.
The phone stops charging before 100%
Just like other phones it has battery indicator in the form of cell/battery.
It should appears filled/full when charging is full and as the battery drains it should gradually appears empty. Now the issue is that it never appears full. The extreme right side of the cell/battery always stays/shows empty.
In other words we can say that the phone stops charging before 100%.
Beside this the indicator works fine and the battery life is also ok.
I bought this phone in UK and currently working in dubai so I cannot take it back to the store.
This happened to me, for the past week+ (I bought the phone on 28th).
I don't know why but an Overnight Charge didn't seem to be long enough for it to charge fully, it was always nearly charged.
However, This morning it seems to have charged 100% so maybe it's just a matter of time? Maybe the battery isn't in sync or something when you first buy it.
Think the battery icon is a bit dodge. As long as you get the green indicator light you know it's fully charged. If it's still orange then still needs topping up.
I've not had a problem charging myself but what I have found is that sometime the indicator says it's nearly dead. Reboot and sudenly there is an increase in amount of battery left. Very odd.
Maybe you need to wait a few weeks just to let it settle.

That isn't acceptable for obvious reasons, so I hope that isn't the case.
P.S. 14-30 day return/exchange policies.
All right Dudes!
The problem is fixed. Simply fully charge your mobile phone and then full discharge till it turns off by its own. Repeat the procedure three times and you are done.
Good Luck
I have the same issue, if you turn the phone off and back on when the light turns green, the battery icon is then full.
So seems like a software issue to me.
My HD7 is going back tommorow anyway, keeps resetting itself and when trying to video in 720p it looses focus!
I previously went back to O2 store the day after i bought the phone about the original charging issue. They were going to swap the phone but then had no stock. Then my above issues topped it today so took it back and surprise surprise they were out of stock! Apparantly expecting a delivery tommorow but they don't know what they receive till they get it (BS i reckon) so if they don't have any in tommorow I'm getting a refund and going to go for a Venue Pro or just stick with WM 6.5..

How do you "full discharge" the phone? Use it until the battery is complete dead and charge it up again x3?
Yes, use it till battery is fully dead and charge till charging light turns green.
That never worked for me either, infact last night when the phone was flat, I have left it on charge over night and it went green, but showing about 50% charge, turned it off and back on and its then full.
My phone is doing this as well, now. Charges to full on teh charger. Take it off, adn it goes straight to 75% charge - viewable in the Battery Saver by battery level. It's impossible to charge it fully, and battery life is TTEERRRRIIBBLLEE.
Either something is wrong with the phone or firmware, or the OS. Not sure. But I can't use the phone like this. It's as if it has a 920 mAh battery in it. Obviously that shouldn't require anymore explanation.
---------- Post added at 11:25 AM ---------- Previous post was at 11:14 AM ----------
Follow-Up: I'm convinced it's a bug in the WP7 OS. When you charge to full, and take it off the charger, it instantly drops to 75%, then if you put it back on the charger 20 minutes later it goes to 93%?!
Problem is, the OS is set to shut down service, etc. when battery power is low (even beyond the battery saver setting, IIRC), so the bad information the OS has can hamper usability. It's basically cutting 2 hours off your battery life when you unplug the phone after a full night/day's charge.

And kill the battery, forgot to say.
Charge on the wall charger, not PC USB.

Battery Life - Significantly better if taken off charger immediately?

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.

Charging problem! slow or no charge..

ok, over the last week or so ive had this issue, gradually getting worse...
my battery will charge to around 40-45% and then charging will slow right down.
two hours later, it will be on around 50% if im lucky, and about 3 more further hours before i hit 60% (this is some of the time, other times, it just remains on its current charge%)
if i leave it overnight for about 10hours or so, highest it goes to now is about 73%, but this is rare, usually 45-50%ish.
ive tested with htc ac wall charger, htc usb, blackberry charger, car charger and a random microusb wallcharger. all have same issue.
when tested with two friends desire hd's on different days, my battery charged perfectly, and at the normal gradient speed over the % range. and my phone reads it correctly at the 100%-98% when back in my phone after change back.
i thought it was down to my phone, just dont know if its rom or hardware. shud i factory restore, or claim on insurance?
i have another issue here...http://forum.xda-developers.com/showthread.php?p=18480603&posted=1#post18480603
which also applies to the question of restore or insurance...
thanks
What Rom are you using, i am using runny 2.2 only 62% charge in 6 hours
9 hours later on battery only upto 68% i have amazing battery life now
i'm using runny 2.2.....left it on charge for 2 hours with phone on, but wifi and everything off and it had only gone up 2% ! !
Turned phone off and plugged in charger, 30 mins later, only went up 1% ! !
72% charge at this point.
So took it off charge, put it in my pocket, went upstairs to bed, turned it on to set alarm and it said 100% on battery....weird!!
matt
Lol this is an issue with calibration. The battery is charging but the software doesnt report it.
You have to charge the phone for as long as possible so you know it is on 100% whether the software says it or not, go into CWM, wipe the battery stats and then let the battery drain fully until it shuts down by itself. Then plug it in and leave it until you know for certain it is at 100%. If the green light comes on leave it for an additional half an hour. Then it will be fixed.
ive only recently got this handset, as last one was replaced on insurance a month or so ago, and its runuing on stock rom with latest updates....?

Battery won't charge past 98%

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.
Thanks guys im happy if its one of those oem quirks.

Won't charge to 100%

Anyone having an issue with their phone only charging to 98%? It will only each 100% if I unplug it for a bit once it reaches 98% and then plug it back in.

not seeing that on mine.
It does this by design. It prevents battery damage and prolongs battery life (in terms of life expectancy and usability over years).

I've had the 98% issue since day 1. I've never seen 100%. It appears to be a very rare issue. Otherwise my battery performance is great!

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%...
