New to VM & Android. Picked up two Optimus V phones a couple of weeks ago. While on the wall charger, both exhibit different behaviors once they've reached full charge.
On one Optimus, once the phone is 100% charged, it says "Full Charge" (or "Fully") on the lock screen. As it stays on the wall charger, the status remains full charge - there is no discharge.
However, on the other Optimus, once it reaches 100% charge, there is no mention of any charging status on the lock screen. And when I check the status in the settings, the phone shows that it is discharging, even though it remains on the wall charger.
The discharging status bears itself out as it remains on the charger, I'll eventually see the percentage of battery life drop.
Did I inadvertently switch a setting? The phone discharging itself once it reaches full charge even when on the wall charger is a problem. This is especially evident when I leave the phone on the charger overnight. In the morning, instead of starting the day fully charged, I'll see it at about 80% charged.
Thanks for any help.
There are not any settings in the Android operating system that affect charging directly. This is more a function of the kernel/hardware specific. This is why some phones can charge while off and others must be turned on. Try trading chargers/batteries between the two phones and see if the problem follows the hardware. Be sure and do this one part at a time, i.e. first trade batteries. Then if that isn't it trade chargers. You could have a bad battery and/ or charger. Also, are you rooted? Running custom Rom? These factors can also affect your situation.
Thanks for your advice. I followed what you instructed. First, switched the chargers to no avail. I changed the batteries and still no change.
It's odd to see two different behaviors exhibited by the same model phone. Both phone are unrooted running stock rom. As I indicated, one phone (which I consider the normal one) does not discharge as long as it's plugged in. The second phone starts discharging once full, even though it's plugged in.
The problem is when I leave it plugged in overnight - if I don't catch it at the moment it reaches complete charge, it'll discharge. Since I'm asleep when the phone reaches a full charge sometime in the night, by the time I wake up, I'll leave the home with a phone that is 60-80% charged.
I'll chalk this up to something faulty with the board and just turn it back in to Target.

This might be wishing the impossible but I was wondering if there any charger and/or dock on the market that will automatically cut the power when the phone is fully charged.
I know the concept is workable because I've seen a different product that works along the same principles - a trailing socket that completely cuts the power when the load drops.
This could be adapted to suit a phone charger so that when it drops to a trickle, the charger cuts the power completely.
I know it's probably unnecessary but the reason I'm asking is that I know it's not advisable to leave your phone on charge overnight but given how easily the HD chews it way through batteries, having to do so is bound to prove inevitable at some point and I'd like to avoid having to switch off my handset when it does happen (after all, what's the point in having a phone if you can't be contacted on it?).
I suppose the alternative is some sort of program that chimes when the handset is fully charged, so that I'd be woken up and can take it off but I'd rather have a good night's sleep

Why do you think that?
Surely the charging circuit is controlled by the handset, and it stops feeding power to the battery when it is fully charged...
Two parts.
Firstly, whilst there is a charge control circuit in the handset, that's all well and good whilst the handset is off but not so good if it's left on.
If the phone is off, it will charge 'til full then drop to a trickle charge to stay there without damaging the battery. If it's on, it will do the same thing, except when the phone checks in with the network or does anything else that uses the battery, the charge level will drop, the charger will ramp up to full power, hit maximum, drop back down to a trickle and so on - it's just not as good for the battery over time.
Secondly, it's better for the environment.
Since I first posted this, Carphone Warehouse in the UK has released a range of 'eco-chargers' for Nokia, SE and Samsung phones that cut out when the load drops (ie when the phone reaches full charge) and will stay off until the user presses a button on the wall plug.
It's a good idea, if a somewhat-impractical design. Placing the button on the wall plug is a bit stupid IMO.
I was actually using a Motorola wall charger at work recently and it seems it has the same function built-in.
When I checked to see if it was fully-charged, my HD wasn't showing as being connected to a charger, it was just showing a full battery. At first I thought it had been un-plugged it switched off by a colleague but when I checked, it wasn't. So I disconnected the phone and re-connected it and the charger symbol appeared in the bar at the top of the screen but, lo-and-behold, a few minutes later the same thing had happened.
Surely chargers these days are intelligent enough to drop to virtually zero output once the battery has charged and then only supply sufficient to maintain that charge.
It's not like leaving the tap on in the bathtub running overnight and flooding the bathroom.
The vast majority of chargers are capable of trickle charging but I already addressed that in my last post.
It was working fine before I went to bed last night, then I let it charge for the night since that battery was at about 4%, But this morning it won't turn on at all. The battery feels warm as if its been charging but nothing seems to be making it turn on. Any ideas?

If it was my phone here is what I would do.
First I would see if the phone charges the battery by putting the battery into
the phone and plug the usb cable from phone into the wall charger or into
the computer.
If the display on phone shows a picture of a battery charging let it charge
for an hour more or less and try turning on the phone.
If the phone is not charging the battery I would purchase a cheapy battery
charger and battery combo on eBay.
You can find this combo on eBay for less than $8 bucks shipped for both the battery and charger:
http://www.ebay.com/itm/1800m-BATTE...045605?pt=PDA_Accessories&hash=item43aa9a4465
(even if you decide to return and exchange the phone its still a good thing to have a spare battery and charger)
Check it out.
Good Luck!

are you on cm7? not sure about the s2 (never had the issue), but i know that on the infuse, there was a problem (or maybe it was intentional) with low power charging mode (phone wouldn't charge when off).
i think this can be solved by trying to charge the phone via your computer usb, as opposed to your OEM wall charger.
Thanks for the suggestion. It definitely isn't showing the picture of the battery when its plugged in to the wall or the computer. I'm debating the battery charger combo you linked.
I actually am. But I have it plugged to my computer and nothings changed.
Time for some trouble shooting.
Start eliminating possibilities. You need to determine where the problem is.
From what you say, it seems possible that the battery is completely discharged but not recharging. That could be a bad battery or it could be the phone.
If you know someone else with an SGS II, try inserting their battery temporarily to see if your phone will boot. If you don't know someone else, maybe you can borrow a charged battery from the store where you bought it.
Continue on until you pinpoint the problem.
Do NOT buy a "cheapie" battery for your SGS2. Unless you want to eisk causing damage. The stock battery for the SGS2 has NFC technology built into it. Using anything other than OEM could cause damage/performance issues to your phone, and void the warranty.

Have goh tried a battery pull? Unplug the phone, pull the battery and let sit for a few minutes to allow tbe IC's to discharge. Put battery back in and try powering up the device. Good luck.

Similar issue and got phone fixed finally
Have had similar issue as yours. Cable charger was plugged into the phone to be charged at night and was surprised to find that the phone became hot and battery was not charged at the next morning, in fact the battery level got lower than it was before charging.
Notes:
- ROM in use: AOCP version 7.2 (Android 4.4.2)
- Kernel in use: Version 3.0.101 [email protected] #3
Here are some tests done and the observations after getting a charger with a slot to place the removed battery for charging:
1. Charging via USB cable connected to PC:
- With the phone turned on, battery charging icon is only displayed after some wiggling at the charging port. The phone got charged further to 100% when the initial remaining battery level is 90%. However, when the initial battery level was less than 50%, the battery level continued dropping ALTHOUGH the battery charging icon was displayed.
- With the phone turned off, battery charging icon is only displayed after some wiggling at the charging port. When the initial battery level was less than 50%, the battery charging icon displayed only a battery level of 1% and the battery level did not increase at all after 15 minutes of charging.
Initially suspected that it was a dead battery issue and bought an i9100 battery, I thought it was a compatible battery at first. With the i9100 battery, I repeated the above tests.
2. Charging via USB cable connected to PC:
- With the phone turned on, battery charging icon is only displayed after some wiggling at the charging port. The phone got charged further to 100% when the initial remaining battery level is 90%. However, when the initial battery level was less than 50%, the battery level continued dropping ALTHOUGH the battery charging icon was displayed.
- With the phone turned off, battery charging icon is NOT displayed but the phone screen flashed continuously, and at times the phone is turned on automatically as the USB charging port is inserted. When the phone is turned on, the charging proceeded as the above sentence.
Upon searching the forum, I found that i777 has a different battery with NFC chip and i9100 battery has reported to cause issues during charging on i777 devices. There was also a Chinese forum which mentioned that the battery compatibility issues should have been overcome in ROM with Android version 4.0 and above.
I then bought a new i777 compatible battery and tested charging via USB cable. The observations are same as the first battery as at 1.
With the battery issues possibility eliminated, I approached a phone technician to examine the phone by telling him that the phone couldn't be charged and the battery level continued dropping even with the battery charging icon displayed. The phone technician then thought that the USB charging port to be the cause of the charging issue and replaced it. The replaced part is the small metal housing where the USB cable is inserted, and is replaced by heating the old metal housing and replacing it with new part by soldering.
The phone could be charged with USB cable as usual after the part replacement and all the batteries are found to be still working fine. Ended up with 2 i777 batteries and a i9100 battery, may be I could continue using this phone for at least another 5 years down the road.
Okay so I've this problem where my battery discharges while charging!
I had this problem since wednesday that time I was on stock... So I thought flashing a custom ROM now as of now i'm on SonyStyle still the same problem,
let me elaborate my problem a bit more
-To monitor how much current is discharging n charging! -498 mA while discharging n -298 mA while charging it normally
-So next thing I tried is to charge it while being switched off, most of the times it wont charge n when it'll charge it'll reach some point n starts discharging! Discharging even when its off and plugged to the charger! BIZZARE isnt it?
-Now in order to put it on chrging i've to reboot it couple of times untill battery monitor widget shows +current... N when it reaches 100 it'll begin to discharge like it'll be empty in 1nhalf hour
-ALSO I'VE TURNED OFF ANYTHING THAT SUCKS BATTERY! AND I'M NOT USING MY DEVICE WHILE CHARGING! ALSO IT DISCHARGES WHILE BEING ON CHARGER IN A switched off state.
these things i've already tried
-Flashing custom ROM
-Putting my cell on powersave CPU governor
-undervolting
-charging using USB
-CUSTOMER CARE CENTRE only resets the software
I'M SO FRUSTRATED THAT I'LL BURN THIS CELL INTO ASHES! Anybody help me before I kill thislil fellow!
You might try resetting your battery stats on clockworkmod or xrecovery. Charge until 100% and let it discharge naturally to switch off, allow a few days of charge cycling and it should be ok.
Lipoly batteries dont trickle charge. If you leave your phone on charge for 8 hours it will just switch off the charger, discharge for awhile and then switch back on the charger. Most take 1 to 1.5 hours to charge, so if you leave it plugged in you will be charging/discharging about 6 times in that period. Lipoly have a limited number of charges before they diminish, usually about 500. So if you leave it plugged in you can reduce your battery life span considerably - otherwise it should last a good year and a half before it wears out.
Dont ever try to trickle charge, overcharge or manually discharge a lipoly battery as they have a tendancy to explode.
The good news is lipoly batteries are cheap to manufacture. You should be able to pick up a decent bst-38 (or substitute) on ebay/amazon for around 15-20 euros. Dont be hoodwinked into the 2000mAh batteries, most are fake. My 970mAh can last 2 days on Gintonic rom.

I had a similar problem with the battery discharging whilst charging.
For me the problem turned out to be my USB cable becoming faulty. It would still transfer data when connected to a computer, but would get a similar problem to the one you describe when charging. Might not be the same problem for you though.
I am now experiencing this problem. I think it is my usb cable too. Will buy another 1 soon. It discharges then charges again when I pull out the cable and plug it in again.

Well already tried wiping battery stats
heres what I've discovered till now
-The charge current drops as if the battery is at 91% but it isnt even close
-It is either the battery is sending wrong data to charger, or it is faulty
-Not able to explain how n why it discharges even a switched off state???
-Only solution I can think is a charging dock for BST-38

If I leave my cell on charging for 8 hours, then after 8 hours my battery will be zero... It'll keep blinking the red light for hour or more... See thats a wicked problem...
happened to me also, had to use a better cable (don't use thin and/or long cables)
Yeah I tried with a Nokia made cable and its charging flawlessly! This is my first time with a Non-Nokia n so far the experience is not very good!
btw thanxxx a lot for your attention n concern!
- similar (identical) problem, tried similar resolutions (factory reset/sdcard/sim removing/different chargers/battery replacement)
- disassemble my phone... and found out, that micro usb connector replacement is unrealistic.
- watched charge/discharge/voltage/current/temperature process trough battery monitor widget (1 minute sampling)..
- re-calibrated battery many times
RESOLUTION : micro usb connector or connections in mobo is dead. I build charger with current meter. No matter, what says my phone about charging (pluged in - discharging)- any information displayed delays for minutes on phone. IF my external current meter says - "charging", than phone state is "CHARGING" independent from what phone is displaying at the moment. Moving usb charging connector in phone causes current to stop flying to phone or reducing current value. Phone still says "plugged in" and or "charging" on "discharging"...
Temporary resolution: little pushing/deformation on charging connector (male) and LED in charging chain, witch is displaying - charging or not. Every time connecting charger i'm looking on indicator LED and moving charge connector, till LED says "charging" and then no more any moves on phone.
Future resolution: contact-less charging trough inductive coupling
I've been having issues with my phone charging. Took it to Telus and I got a new one. Problem kept occurring so I got the battery replaced as well. Despite basically getting a new phone I'm still having issues. Basically say I'll have 14% battery, I plug it in overnight and come back and it's 34%. So it charges 20% in 7 or 8 hours in the wall charger. I'll then turn it off and pop out the battery, put it back in, turn it on and I'll have 60%. Within a few minutes I'll have 50%. After an hour of use or so it'll beep saying I have 15% battery. I once again pop out the battery and then it'll say I have 40%. I don't even remember the last time I've ever got over an 80% charge or even a 100% charge. I'm lost for ideas at how to fix this.
I'm running ICS S-On, but rooted.
Thanks.
PS The picture I've attached shows what I was talking about. When it was at the bottom red when my phone died saying it had over 20% battery I plugged it in and left it charging for about 14 hours to find it at under 30%.
Sell it and get a better phone
You probably are flashing something wrong or have a rogue app... but there are better phones and its the "black friday" time of year. Just get a better phone.

Have you tried using a different USB cable and/or adapter? Either or both could be faulty.
Give Better Battery Stats a try, and see if it can point out some apps that are running that you were unaware of.

Alternatively, based on what you're saying, you might need to re-train your battery stats. Since you used a new phone with a possible bad battery, when your phone depleted itself on that bad battery, that might have trained the battery stats improperly. Retrain your battery stats and see if that will help you out.
Instructions on that are provided here:

—Edit—
I just re-read OP and noticed you advised it NEVER hits 100% charge - Few more things to try:
Firstly, try shutting phone off and charging it OFF overnight, as that might charge it faster.
Secondly, if that fixed the issue, try a different phone charger. Either your USB cord or the USB adaptor (or both) might be bad and not supplying sufficient power.
Thirdly, if that didn’t work, try a different wall outlet – I have run into a few wall outlets that don’t supply sufficient enough power to charge a device.
Finally, if everything I advised fails …… get a new phone. LOL I’d suggest a new battery, but you already did that. If you still have your old one, try the steps I suggested with that battery as well.
Yeah, you could try a different battery or charger. Make the the battery is genuine OEM and new just to be sure, and/or try getting that T-Mobile branded micro-usb charger that outputs 1,000 mAh.
First I don't think anything is wrong with my device but just curious if anyone else noticed this.
1. Fully Powered off device
2. Plug in charger (little battery charging icon animates)
3. This is where it gets strange I let it get to 100% but didn't unplug it (left it plugged in all night like I usually do on all my devices) , next morning I check the charge and it showed 97%
so I assume the phone circuitry shuts off the charger after it's fully charged to prevent overheating or whatever, or the charger shuts off, strange why I got a 3% drain though with it completely off...
so far I have only tried with the official charger and cable, curious if anyone else had this issue.
besides for that the battery in this device seems good I can get about 1 day 1/2 moderate / heavy use out of it
Perhaps it's the boot animation etc?

I guess it could be if it runs in the background , it just was strange to me since my samsung tablet will always show 100% even if I leave it plugged in forever, maybe lithium-ion (samsung) and lithium-poly (xiaomi) have different charging rules like maybe you can't float charge lithium poly (just guessing)
