I had my new HTC Desire 3 weeks ago. Those last days I plug my HTC to the charger overnight and when I take it back in the morning the battery is only up to 92-93% and the led is green, like it had a full charge. If I unplug-plug the device, it will resume charging, this time up to 100%.
Is this a normal behaviour for a battery 3 weeks old?
How can I fix this?
This is normal behavior of the phone. It charges up to 100% and then stops until the charge drops down to 90%, at that point it starts charging again up to 100%. This is what you have noticed, there is nothing wrong with your phone or the battery
This worked, even though I am no longer worried about it.
1) After green light unplug phone and wait 10 minutes
2) Shut phone off
3) Plug back in till light green
4) Turn back on
Poof, 100% but other than that the above post is correct, not a problem. I bought an extended battery for mine. 3,000 mAh and have no problems.

I have a wierd issue on the new purchased TP2.
I am recently I owner of Tytn II, just switched over to TP2. Once I received the TP2, it came in a full battery status. Then I used it all up and then proceed to my 1st charge ( over 12 hours, with phone off)
Things happened after I woke up in the morning.
1. No lights on for charging ( I assume that's a new feature when battery is full, instead of charging when red )
2. once I turned on and shows only 45-50% of battery status.
So I used it all up again, and see if it charges on the this time.
I am just wondering if anyone have this charging issue.
Dude, you are not treating your battery correctly. The below link has some useful info. Especially the link in post 3 by Sjuust.

Btw, when it's charging, the status light will be a solid amber. When fully charged, it's a solid green. If there's no light, check your wires and stuff. Perhaps it's a bad socket.
Just doing a follow-up on the issue, the 2nd time not successful too
I tried and it worked only when I turn the device on to get a full charge.
Anyone think it's weird
Seems you mini usb does not connect propper. Try another cable, if this works you know the problem.
Or: press the male side of the mini usb each direction until you see a light burning. If this happens the usb opening in the phone is broken and you should get it fixed.
If this all does not work, still get it fixed. It's probably not the battery, but the usb opening in your phone.

that is very unusual as when phone is fully charged it stays on constant green light(led). at no time should it go off. unfortunately your battery may just need a few more normal charging cycles to achieve its full potential. if the led light goes off that is another issue! have you added any battery customizations?
Same problem here
I have - more or less - the same issue as D810Noob. My TP2 came fully charged out of the box. First time I charged it, the amber light was on during charging. Next morning no light was shown. I am not sure, but as I recall it, the battery was 100% charged. In the recent days, after one night charging (phone switched off) the green light is being shown but battery meter shows 89% (yesterday) or 91% (this morning). I have the 1% increment battery driver installed with the greenbatteryfix-icon installed.
This morning, after having switched on the phone and after having been confronted with 91% charge status, I reconnected the phone to the charger until it reached 100% (left the phone on during charging). With only two calls of two minutes in total and gprs (no hsdpa) running for two mail accounts, battery status dropped two 80% in 5:30 hrs. Never had such a drain with my TYTN2 that had (more or less) the same configuration.
It may very well be that my battery is not (yet) calibrated correctly, albeit that I fully discharged it last night. I will redo this a couple of times before returning to the shop, but this needs to be improved otherwise I will go back to my TYTN2.
Cheers, Dela
Still having this issue. I have drained my phone completely yesterday evening until it switched off itself. Ten restarted until it switched off again. Then had it charge for forteen hours (phone switched off). When I switched on the phone this morning, battery meter showed 96%. A bit more than an hour later it shows 80%. Had no phone calls, only receipt of six emails and half an hour drive in my car with BT connection. BT is on continiously, BTW.
This does not look good, does it? Anyone who can shine a light on this?
Cheers, Dela
PS: the charging light was green when I took it off the charger this morning, whilst the battery meter showing the 96% charge status right after the startup.
Does anyone have a link for the thread that discussed the correct way to wipe battery stats when upgrading to a new Rom? I remember it went something like drain dead, charge to full, drain dead again then charge to full and wipe stats. I can't remember the complete process. Thanks for the help.

I've seen a couple different threads on that here, one saying discharge fully then charge while powered off, and the other saying to do a full charge "conditioning cycle". I did the latter and it seems to have made a difference.
Here's what I did:
Charge the phone fully with it powered on
When fully charged, disconnect cable
After green LED goes off, power the phone off
When phone is fully powered off, reconnect cable, amber charging light should be on
When LED goes green, disconnect cable
Repeat previous two steps 10 times
After 10th cycle, boot into recovery and wipe battery stats.
I am using Amon Ra recovery which has the wipe battery stats option under the Wipe option. I never did this when I had Clockwork recovery installed, so I don't know if the option is in the same place.
Being an electrical engineer, I find this business of battery conditioning interesting, along with the Ni-Cd "memory" vs. Li-Ion "no memory" issue. If anyone has found a decent physics-based explanation as to why these things do or do not have any basis in fact, I'd appreciate a link. Yes, I'm too lazy to Google it at the moment.
Hmm, I may have to look into this again. I charged my phone all night (powered off) and unplugged it this morning. I did nothing with it this morning but turn it on and look at it, then put it in standby (quick press of power button). It lost 16% of charge in less than 2 hours!
I'm running BS1.2 with the Baked1 (low voltage/best battery) kernel.
Damn, just installed System Panel and found that my CPU is at 100% constantly!
I'm trying this now. The longest I've pushed my battery was 22 hours... and that was with 39 minutes of screen on time, lol. In standby almost the entire 22 hours....
Ok, I believe my issue was related to a camcorder problem, my CPU usage has dropped back to normal levels after fixing that separate problem. After my battery recharges fully I will see what happens with the charge.
the other methods to do "calibrate your battery" (which isnt really calibrating the battery but the battery stats of the phone so it can accuratly judge when it stops and starts charging)
1) charge the phone to full
2) unplug and use phone till it shuts off from no battery (do not plug in until it shuts off)
3) charge phone to full again with out unplugging till 100% (check under about phone > battery it shoudl say full charge there)
this should reset the battery stats.
the last method is one from HTC
1)Charge the phone for 8 hours uninterupted with power on
2) turn off the phone and charge for an additional hour
3) turn ont he phone unplug it and let it sit for 2 minutes then plug it in for an additional hour.
all 3 methods listed should help. I personally dont like the x10 method because it has the potential and basically over charges the battery to make sure it is acctually at a full charge. It is much faster then the other 2 methods though so to each there own.
Dont waste your time on...
plug/unplug 10 times. It really doesn't recal the battery.
the unplug/plug 10 times.
1. Phone on...charge until green light comes on. Immediately unplug and turn phone off.
2. Plug phone back in until green light comes on again. Immediately boot into Recovery and wipe battery stats.
3. Use the phone on battery until dies.
4. recharge phone to 100%
You are good to go!
If I tether during the day (5+ hours) a lot, is it bad on my battery? Isn't that like a constant charge or does once the LED turn green it stops trying to charge?
Thanks.

the evo doesnt do a trickle charge so when the light turns green it stops, this is why you will almost always drop 1-5% battery rather quickly.
Are you sure? My light has been green for a while, and my phone battery status says 'Full'.

There's a lot of confusion over how the battery / charging circuit works and how it reports. My advice is to just charge until it's green and full, then unplug it. If you leave it plugged in all night, unplug it for 10 mins in the morning, then plug it back in to top off.
That doesn't really help me SilverZero, my question is only if leaving it tethered (which means connected to USB) is bad for my battery.
Well on mine i would check it every once in awhile and i would see that once it get downs to under 90% that it would charge again till it recognized that it was full again. So based on that i dont think you should have to worry about it. It seems to only draw the charge when needed. I also leave mine plugged in alot when im home so its good to go when i leave and havent noticed a loss of battery life at all.
You guys don't want the charger to trickle charge. Li-Ion does not accept overcharge, even 0.01C (15 mA on the stock Evo battery) will cause it to vent and probably combust.
So does "calibrating the battery" calibrate the phone or the actual battery?
I ask because I have 3 spare batteries, wondering if I have to do this for each of them??? They are all standard size, one of them OEM
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!!

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....?
So I've noticed for a while now that when I disconnect my dInc after charging, the battery will drain almost 20% within the first couple hours (almost no use at all). I suspect that the battery isn't being fully charged when the green light first goes off. After I plug/unplug the cable and charge a couple more times, it holds a higher charge more consistently. I've read this is due to the phone not wanting to over-charge the battery, however in the case of my battery (Seido 1750), it doesn't even fully charge.
Is there any way (aside from the plug/unplug scenario) to fully charge the battery in one go? An app maybe?
My phone is rooted.
Thanks.
The battery could be losing its ability to hit its capacity. In other words its wearing down.
Nothing will fix it. There are no apps to bump charge.

Get an external charger for your battery and couple of extra batteries. I get best result not charging in the phone and rotating batteries.

Charge the phone powered on until the light turns green. Leave it plugged in but turn it off. Leave it plugged in, off for about 20 minutes, you will notice the light is still orange even though its already "charged." Once the light goes green again, unplug it and power it up. When I do this, my battery will go for 3 or 4 hours before it hits 90 percent with my regular use.

Just be aware that bump charging as it's called, can reduce the life of your battery over time.
Battery discharging while on charger.
The past 2 nights I've had the Acro S on charge via the wall charger through the USB plug (not in the cradle - due to a protective case) and during the night I noticed the phone charge with the Red LED showing and then it goes Green showing it above 90% - then later on in the night/early morning I've noticed the green light has gone out and checked the time and noticed that the battery has discharged to 80%
Looking at the battery stats it shows the phone had reached full capacity and then been discharging for a number of hours - the odd thing here is that the plug was still firmly in the phone and plugged into the wall with no chance of it being bumped - the other odd thing is that the charging lightening bolt was also still showing but the percentage was going down as I was trouble shooting all this.
Eventually I unplugged the phone a couple of times and the phone started charging again and reached 100% and was still like this when I picked it up to use it for the day.
This has occurred 2 nights in a row.
The manual says that the phone will reach full capacity while on the charger and will also self discharge and recharge again by itself but I think a 20% drop is a bit more that what would be considered normal especially when you want the phone fully charged in the morning.
If anyone knows what is going on here or has experienced this kind of behavior I'd be keen to know about it.

Nobody else has this problem yet I see.......
Its been a few days and this morning I've got the following
0650 hrs - battery showing discharge after being on the charger all night - red charging LED on and screen showing lightening bold charging symbol but battery still discharging and sitting at 81%
0701 hrs - phone still on charge, battery now 79%
0741 hrs - phone still on charger, battery now 77% - I cant believe that this is part of the battery cycling on charge
I'll contact Sony today and see if the battery is faulty - phone is only 2 weeks old.

Ok - so yesterday I went to the Sony support office in Khyber Pass New Zealand and the tech there said they dont support Acro S because its not been supplied by a NZ Sony distributor. So I then went to the place I bought it and they didnt want to look at the phone because its Rooted - I didn't tell them the boot loader is also unlocked - but they gave me an adapter so I could use the official Sony charger that I got with the phone (until now I've been using my old Xperia Neo charger) in the hope that the lower voltage rating might change things (they'd had acro Z which didn't charge on the Neo type charger they supplied).
So I got home and changed the power adapter over to the one that came with the phone using the adapter plug.
Last night I put the phone on charge and woke this morning to see that it had charged fully again and then since around 0400 it had discharged to 83%. I unplugged the phone and plugged it in again and it did not start charging - I did this a number of times and it didnt start charging but it did show that it was charging with the red LED and the lightening bolt on the battery and everywhere else it showed charge but the graph kept going down and the percentage kept dropping.
I had to reboot the phone for the battery to start charging.
I decided that I would re-lock the boot loader and repair the phone via Sony Update
Relock thread http://forum.xda-developers.com/showthread.php?t=1863179
Sony Update

On page 3 of the relock thread I found this http://forum.xda-developers.com/showpost.php?p=44093334&postcount=28 and waiting a reply from him to see if his issues were similar.
I've - re-locked and used Sony Update so now I'm back to square one I hope - I'm still going to root but I'm not going to bother unlocking the boot loader because I didn't find a kernel that could read external hard drives.
I'll update this if the phone continues to have a faulty charge...........
