Desire Battery Voltage Issue

Hi all,
I've been having issues with my phone lasting nowhere as long as my girlfriends identical one,
I installed Quick System Info on both phones, Killed all tasks.. Not only is my display duller than hers on the lowest setting using the power control widget but the voltage on my battery is 3737mV while hers is 4071mV..
Is this cause for concern?
Update, forgot to mention, this is from a full charge on both handsets.

Sounds like your battery is fu#ked!
There seems to be an issue with the way android reports the battery voltage. If I leave my phone on the charger until the light goes green and the indicator says 100%, the voltage will often report between 4.146v - 4.156v.
Upon unplugging the phone would drop to 99% and 4.125v almost immediately.
I noticed the other day that after leaving the battery on the charger overnight the voltage was reporting as 4.206v and I was able to use the phone for over 15min before it dropped to 99% from 100%.
Minimum voltage before your phone powers off is around 3.6v - 3.650v. So 3.737 is pretty close to the cut-off point. The OS is may report 100% charge but your battery is not holding charge.
I had a battery on a different device that was like this. The battery had collapsed. I could charge it for 24hrs and it would not make a difference. Within 30min of use or 1 phone call it would die.
Does your battery have any bugles, bumps or protrusions? This is often a sign of a collapsed battery.

Edit: Don't write when you're tired, silly things come out of your fingers! Soz!

have you tried to swap batteries between the two phones. That will exclude either your phone or the battery from being faulty.

Yes, after scratching my head for a few days I did eventualy come up with the genius idea of putting the battery from the other phone into my phone!! and after charging it up, set it down for an hour and then checked and the battery was on 98% !!
So it looks like there is something wrong with my battery, This morning I woke up and my phone had been charging for 7 hours and was fully charged, I looked at the battery meter and it said 100%, I turned the phone off then back on and checked again.. 90% ???? WTF ??? just from turning the phone off and on?

[Q] How come the phone does not sleep when charging?

I'm still relatively new to the whole android platform. Evo being my first. Why does the evo not sleep when charging? I have the issue of rapid battery drain when I unplug the phone from 100-90 in a matter of minutes. This bugs me to no end. The only way I am able to get around that is to watch for the phone to ding 100 and immediately unplug it and turn it off.
I believe that, and (correct me if im wrong), if your phone is awake, it is being used to its full capacity all of the time. CPU is running and doing whatever it does that drains the battery like it does when its unplugged and being used by the user.
Since the phone doesn't trickle charge it stops charging at 100% until it gets down to ~90% (all the while still reporting that it is at 100%). It stands to reason that if the phone doesnt sleep while its on the charger, its using this cpu power and this is the culprit of the rapid battery drain, and to that end, the culprit of a lot of people's battery woes.
food for thought i guess. that's my take on it.

There are numerous discussions about the charging thing. Search, or at least Google. The most intriguing answer I ever saw to this was that the charging system was set up to protect the Li-Ion battery from degradation by not cramming it full of charge all the time. (The OP on that was a bit more technical, but you get the idea.)
If it bugs you that much, you could root your phone, flash a ROM that is undervolted and compatible with SetCPU, install that, and then set a profile up so your phone is underclocked when it's charging / charged.

I searched xda prior to posting specifically about sleeping while plugged in. My query isn't neccisarily about charging bit rather the sleep function and awake state of the phone while its pretending to charge.
I'm curious as to whether this is hardware related or not. For example when the phone reaches 100% and stops charge could the phone then actually begin to sleep. Unless its physically impossible for the phone to sleep while there is a usb chord plugged into it.
A little test I did with this over the past two days. At night I charged to full and took the phone off the charge and went to bed. I woke up and only lost about 4% all night and was able to use the phone on the way to work never going below 90%
The next night I left the phone on charge all night. Wake up take it off the charger and within 10 minutes I'm down to 92%
Keep in mind I'm not blaming charging on this. The first night lasted longer off of the charger than the night on the charger simply because the phone was allowed to sleep through the night.
I could be wrong

you can set the options it will say 'screen stay on while plugged up' or something to the like
or when you plug it in, just push your lock button (the top power key)

also you can get a brightness widget and put it on your home screen. that way you can still have your screen on while charging but it will be dimmed or whatever setting you set it too.
hope this helps!

Your screen being on vs off while charging does not factor into the asleep vs awake time of the phone.
for an example of this, a freshly rebooted phone on the charger, with the screen off for 5 minutes, will have an "up" time of 5 minutes and an "awake" time of 5 minutes.
this is true while the phone is plugged in and the screen is on or off.
simply put, your awake time on the phone is always going up as long as the phone is plugged in, double this with the fact that the phone stops charging at 100% and you have constant drain even when plugged in.

the phone shuts off at 100% to protect the battery. If you want your phone asleep then turn it off at night. that is the only way to put the phone to sleep try searching app market. Other then that the only other way is to push the power/lock button at the top

Mobile internet fail. Sorry double post

Moto 360 won't go past 92% charging

Hey guys just checking in if anybody has had this issue and a solution. My moto 360 charges up until 92% and then discharges after that point. It never gets to a 100%. I've tried rebooting the device, even resetting it and it's still stuck at 92%. Any help would be appreciated. Thanks!

I may have the same issue as of late. Cant seem to get it past 94%.....

I was having the same problem. I let the moto 360 battery run out completely until the watch turned off, then I let it charge on the dock overnight. It sits at 100% now, but the dock light never goes off.
cycling the battery a couple times might help, it did for me at least.

For me it didn't get past 98% for a good 4 hours within the first few days. So it's all about the charging cycles. Well for me anyways. Mine charges pretty quick to 100% now without much issue. This is with the 4.4w.1 update of course.

I just received mine yesterday, set it up, charged to about 97% last night and turned it off. Woke up this morning and finished the charge before leaving for work so that I was starting with a clean 100%. So far this morning I've been playing with it pretty heavily and showing it off to people at work but did notice that the percentages have been swinging back and forth a few times, like for example, after a period of heavy activity I checked the battery and it was at 94% but in checking a few minutes later it was up to 95%.
This sort of reminds me of when I flash a new AOSP rom on my phone and it takes a day or so for the battery and software to get in sync with each other. The graphs on battery history (still talking about the phone) show percentage going up a little, like the software predicts what it should be but then somehow determines that it has overcompensated and credits you a few percentage points. After a few days this effect goes away on the phone and it appears to settle.

Happened to me maybe 3 times. I dont know what it is. Sometimes restarting works. I even flipped the watch upside down and that worked. one time it stuck at 97% and after it restarted, it showed 100%

Since the new update the dock light won't turn off.

Thanks for this. I completely drained my 360 and now it goes to 100%

This is what I posted in other thread:
I can honestly say that I found the issue of the Moto 360 getting stuck while charges, since I bought it almost 3 weeks ago I hadn't been able to get a full charge in my bedroom, I live in Puerto Rico and here is basically Summer all year, average temperatures 80-85 with lower around 65 degrees on Christmas time and highest around 95-100% during July and August, plus 75-90% humidity. Well, with all that said, my bedroom is closed all day, so when I get home it's very hot, as soon as I get there I open windows and all doors but it takes a while to get it cooler. Since I got the Moto 360, I was getting home, changing clothes and putting the watch to charge, it never fully charged, I've tried everything suggested here and other forums, the only place it charged completely was on my Family Room where I have a lot of ventilation and is way colder than my bedroom.
Last Wednesday I got home and just turn the A/C on as soon as I got there, 30 minutes later I put my watch to charge and it charged fully for the first time, so immediately I realized that the only difference this time was that the room was cooler. So I decided to make some tests and I have concluded that every time I put my phone to charge in a cool room it charges completely, but as soon as I try to do it in a warm or hot room it never fully charges, it's obvious that the watch gets warm and hotter while charging so if the environment in which you are charging it it's even hotter it just stops charging, maybe to just protect itself or something.
Those of you with the same issue, just try this and see what happens. Good luck

Hello,
My Moto 360 seems to be stuck at 83 or 84% after a full night on the charger...
It's been the case for the two previous nights, at least.
I've tried restarting the watch, before putting it again on the charger -> No change, still stuck at 84%.
I've then tried resetting it, reinstalling and charging -> No change, still stuck at 84%
After reading posts where people stated that a complete discharge/recharge cycle would let them get back to 100% charge, I tried that as well.
The good news is that it took 28h for my watch's battery to deplete completely, quite significantly more than what I expected.
The bad news is that it charged up to 85%, then down to 83/84% again while seated on the charger.
In a desperate attempt to find something else to try, I put my Moto 360 on another Qi charger, and the battery level climbed up to 92%, which was encouraging... Unfortunately, it stopped there, and didn't go up to 100%, so I don't know what I can make of all this.
As for the theory about the room temperature, it's always been the same here, between 20 and 25°C (70-75°F), so not anything I would call hot.

So I got mine a few days ago and I've noticed when on the charger I get 2 different level of screen brightness. I've also had the problem of only getting 94% some times 97% but what I found that worked was that if I turn the watch off then put it on the charger it turns on and the charging display is really dim and it gets to 100%. If I just put it on the charger the display does not get as dim. The fastest and best charge is with the display off I've been playing with getting this done but haven't found a sure way to get the display off while charging.

I think there is something to the temperature idea. When I first got it, the weather was pleasant, never going above the upper 70s, so my living room was also pleasant, and it charged to 100% within an hour with no problems. Since the cursed summer heat, of 85-90 everyday, I can't get it past 98%. Which is not too bad, but I can't help waiting for another cooler day (hopefully before the fall) to see if it can get to 100% quickly again.

I do not have any problems getting my 360 to charge to 100%. What I do when charging is to set the 360 on its charger. Then with my phone I turn on Ambient Screen. When the 360 screen dims I turn off the Ambient screen. This keeps the 360 screen dark for quite a while. Works for me.

do you guys leave your g3 charging while you sleep.

I always been afraid to leave my g3 charging during the night. But is it true that it damages your battery.
Should I start to leaving my phone charging during I sleep without worries?

Do it every time, with the device powered off. Power is disconnected when battery reaches 100%, so no problems.

night charge now is safe for your phone. The phone will not recharge until the battery <95% or 90% (still plug in )

I charge the phone overnight every night - with the phone left on. No issues.... As mentioned you can do this now with today's battery technology without worrying about battery memory, etc.

I have done this all the time with all my smartphones. No issues.

Just don't leave it on your pillow or on the bed as it may reduce heat dissipation. But perfectly fine to be left overnight charging.

I always leave it to charge when going to bed, but it gets fully charged only 2-3hrs in, so it stops charging as i have not noticed it heats up excessively. PS: i put it into airplane mode too.
The nice thing about G3 over many other phones (even G2) is the battery is replaceable. Even if you kill it over time, just buy a new battery. Voila.

HTC 10 overcharging?

Hi. Please excuse my English. My HTC 10 remains warm as long as it is plugged in, that is, even several hours after the green led started to flash. All my previous phones aborted the charging process and cooled down after the battery was fully charged (Of course, I use the bundled charger). This is very concerning. Does it mean that the phone overcharges? I always turn my devices off before I plug them in and begin to charge them. Thanks.

I think this pretty normal. What means warm to you? 40degrees celsius on charger is normal for this device. It does not matter if you charge while turned off as the quickcharge technology works either way and will not quick charge after reaching 80% load. I recently read an article of someone who charged his 10 with an google pixel c charger ( usb c 5v, no quick charge). His 10 loaded normally until 100% but charging procedure did not stop and phone shut down after reaching 50degrees battery temp... maybe your charger is faulty!? How fast does it charge?

I can tell you that my phone tends to get warmer (keep in mind I said warmer, not hotter) when it is plugged in and I am doing stuff (Youtube, browsing, etc...). It will most likely keep warm unless you are not doing anything. I try to not charge my phone overnight since I usually get up to go to the bathroom or get water in the middle of the night, and since I only got like 2-3 hours of sleep left that's when I plug my phone in. You say you turn your phone off when your phone is charging so I'm unsure why it would get hot.

Clarifications
Thank you very much, xperia x root.
By "warm" I mean that the actual phone (not the charger) is above room temperature, unlike any of my previous phones, indicative of redundant electrical activity, which, to my fear, might be overcharging. This is why I wrote that I turn my device off before I charge it: it means that the phone does not consume power, and thus that there is no charging-discharging routine going on. I am yet to measure my phone's charging time.

There's really no need to turn off your phone every time you charge it. My phone gets slightly warmer when quick charging compared to using the regular charger from my previous M9. If you Google "overcharging cell phone", you'll find so many articles about how it's a myth because the phones are smart enough to know when to stop taking a charge when it's completely full.

Yeah i meant the phone too. This phone is always above room temp . Nothing to worry about. While Im typing here(chrome desktop modus) my device battety temp is 40degrees. While using phone during charging it even gets 46 degrees warm, before throttling very hard. I'll watch temp today when charging after reaching 100% and post my temp.

Thanks, xperia x root. When the phone is off, it should, eventually, reach room temperature. That's why I fear that my phone's warmth indicate overcharging. I completely understand that it is unnecessary to turn the phone off while charging, but if it is on, you just cannot know if the heat is due to overcharging, or some operation of the processor. This is why it would be most helpful if you would, only once, for the sake of our experiment, charge your HTC 10 today while it is turned off. And I think you shouldn't watch the temperature, but simply touch it with your hand and feel if it is in room temperature or not. And it would be very helpful if you examine the phone's warmth sometime after the green light is on -- one hour, for example -- to be sure that the phone had enough time to cool down. Thank you very much!

My HTC 10's charging time looks normal, on par with what you see and hear from other consumers and reviewers : it took 1:33 hr to reach 100% from 10%.
