General :: Galaxy Nexus - Battery Not Fully Charging
Sep 9, 2012
My specific device is a GSM Galaxy Nexus.
So, I have 3 batteries for my phone. 1 stock (1750mAh) and 2 extended (2000mAh). No I don't need all that juice... its a story for another time. Anyway....
Lately when I charge a battery in the external charger (using a USB cable and the wall plug supplied with the phone) the battery will not fully charge. The LED on the charger will change from red to green (Usually I charge the battery overnight, or while I'm away at work during the day). However when I put the battery in the phone, it will show somewhere between 80%-90% charged.
1) Would a 100% drain and charge reset the battery's "fuel gauge"?
2) My phone automatically powers off at 6% (which is fine, needs enough juice to save current settings and power down properly). Is there a way to truely drain the battery down to 0%? (I'm thinking of some kind of low-voltage lightbulb or LED connected to the positive and negative terminals should drain that down to 0%. Is this recommeneded or is it fine just running it down till the phone powers off?
Normally I try to plug my phone in and charge (or power off and swap batteries) once they hit about 40%-60%. I'm only interested in doing a full drain to see if that will get these batteries to fully charge in the desktop charger. Besides I've read from a few sources that it is GOOD for the battery to do this once in a while (Fully drain, charge to100%) to properly maintain them.
And as a side note, charging the battery in the phone (either with the wall plug or from USB cable on my computer) will always result in a 100% charge, which makes me thing the issue is with the desktop unit itself (perhaps faulty circuit that cuts off charge current when it thinks its full ?)

I've had my HTC Desire for about 2 weeks. I have searched through the forums for info...but between threads getting off track or just not understanding anything, I thought it would be easier to ask basic questions about my particular issues.
1) What is root? I have the 2.2 update, I am happy enough with HTC and my carrier (Telus) and I don't need tonnes of room right now.
2) Speaking of room, I try to put my apps on my SD card with the 2.2 update but only Google Earth and Night Sky are able to do it. All of my icon packs etc. wont go to SD. I'm pretty sure I have lots of room left so I dont think this is a huge issue.
3) Battery issues. I didn't do the first full charge as I had to use the phone asap when I bought it. I don't have much going on with my phone, no active wallpapers, just weather toggle and clock, text and a few phone calls, check a couple websites, maybe a video here and there, and sometime use GPS for maps. I keep my screen on zero percent and I soft touch the power button to go black screen when i'm idle. I turn off gps and wifi when not using them. With that said, I cant keep the phone idle and off charge overnight without it going to zero. After a charge I lose 10-20% in the first hour. I have never lasted a day on a full charge.
4) After playing around with customizing my phone with icons and widgets I am done. All I need this phone to do is make phones calls, text and check my favorite websites. I use my tracks when I go running and listen to music when I run. Thats all I want it to do. Its a phone so I would love if it could keep a charge in case of an emergency. I was late for dinner the other night because my battery died and I couldn't even call to say I was late! so....
5) What do you recommend I do with my phone to keep it as basic as possible and powered up?
6) What are the key apps to make this the best user experience?
7) When in my pocket I lock screen but once I found that I had 23 unsuccessful attempts to open screen from jiggling around in my pocket lol. Is there anything to help me with that?

I turn off my 4G/LTE on my Galaxy Nexus to save battery but when charging or plugged in, I would like to take advantage of the faster speeds. Is there a way to automatically turn on/off 4G/LTE in relation to the charging status? 3G on battery, 4G when plugged in.

My sister has a Samsung Galaxy y phone running Gingerbread 2.3.3 (not rooted). She plugged the phone after it ran out of charge and saw this screen (pic attached) with the battery icon empty and a blue triangle with a crossed out battery symbol inside it. The phone would not power up.
We tried everything : checked charger, plug points, usb charging, taking out battery and cleaning contacts but everything is fine.

Prior to getting the Galaxy S, after I read what Samsung were saying in the manual of not to overcharge, I investigated the reasons and wrote in various topics on the battery and the differences between Li-Ion & Li-Pol battery types.At that point with all the evidence found it made sense to believe that what Samsung were saying in not to overcharge was accurate.Basically, at that time it was believed the phone used a Li-Pol, Li-Pol batteries are different in that they are 'wet cell' as opposed to Li-Ion which are 'dry cell' charged.Li-Pol can be manufactured much thinner but can not be manufactured in different shapes.This is to allow the wet cells whilst under charge which become hot to move around the battery freely. If a Li-Pol was manufactured in different shapes like Li-Ion it would create a 'hot-spot' in an area where the wet cell could not move fluidly around the remainder of the battery.However, it has now come to light that this is not the case and that the batteries provided with the phone are indeed Li-Ion.Anyway, moving on to the present.
After now getting the phone and doing a bit of testing I have found the overcharging issue NOT to be an issue.When you commence a charge on the phone the icon changes to a charge state.However, once the battery has reached maximum charge capacity the battery icon automatically changes to a 'Non-Charge' state and then the phone simply runs off it's own battery. This is despite the phone is still connected to the charger. It's just that the charger although still attached is no longer charging the battery.As soon as the battery falls below a certain figure (I've had different figures ranging from 98% right down to 91% which is probably due to whatever the phone is doing at that particular time to wake the phone up from realizing "hey, you are still attached to a charger, now wake up and start charging again").

I'm getting a lot of conflicting opinions. Matchup:
1. This site strongly recommends that you charge your battery before activating it.
2. Other sources have noted that you should start it up and use it until it is mostly drained before charging it.
Does anybody have any scientific evidence to support one theory over the other? What are the consequences of letting it drain before charging if you side with #1?

I purchased an extended battery, a Motorola branded BP7X for a Droid 2 phone. It's rated at 3.7 volts/1820 mAh. I tested it with a volt-ohm meter and got a reading of 4.2 volts.
When I install the battery in the phone and connect the charger (phone is off), the charging graphic shows the battery is fully charged. I can power on the phone with the charger attached, but as soon as the charger is disconnected, the phone dies. I tried this battery in two Droid 2 phones and got the same behaviour. Is this an indication the battery is defective, or is there something I need to do to make the battery work?

My Droid wall charger stopped fully working this morning, and Im not sure why. It may be either that the charger is broken or the port is. When I charged the phone this afternoon on my car charger, it worked fine, but I did notice once that the input piece for the car charger is slightly wider than the wall charger, and the wall charger has seemed to fit loosely in. I cant tell if anything is actually wrong with the silver input piece on the wall charger. Should I buy a new wall charger or take the phone to Verizon to get the the port possibly fixed if that is the issue? Can they even fix the port?

This is my second Nexus. I just purchased a new charge cord because I needed to turn off my nexus to charge properly, and I hated that. But this new cord only did me good for a bit. Now, the nexus refuses to charge, unless you put the cord a certain way, and if you even touch it while charging, it stops charging.Edit-now its not charging no matter what I do

how the Nexus Tablet 7 charges? Not through the USB port, right?
I have a Transformer right now w/ the dock & 2 full sized usb ports on it. But I have been waiting for the Nexus Tab for months, because of the screen, processor, and price. however since it does not have a microSD, I would definitely need to be able to plug in my 500GB usb hdd into it. I would need a OTG cable, right? And it does not use the MicroUSB port to charge, right? Otherwise how could you use the usb and charge it at the same time?

My Nexus 7's (2013) battery was low so I decided to charge it. I plugged it in to a AC adapter and it showed that it was charging. The tablet's battery was decreasing! I decided to turn it off and charge it. I've been trying to fix the tablet for a while. It showed empty battery icon, LED light above the usb port was flickering 5 times. Then it showed no more sign of life. I've tried many things including holding power button for 1 minute, tried different chargers, plugged in a different outlet, used original charger. The tablet is still under warranty but I don't want to go through all the trouble to get a new one. My tablet is not rooted.

I've noticed my Gnex's battery loosing its s#!t and draining rather quickly than before. I mostly charge it by plugging it into my laptop via the usb cable and very few times via wall socket. I was wondering does slow charging via "usb on laptop" damages/degrades battery life? Google search didn't throw any relevant info.

I have had the issue of plugging the phone it at around 9pm when going to bed and it charging to 100% the next morning at around 7:30-8am but as soon as i unplug the charger it drops from 100% to 99 to 97%? Im using the battery circle app to monitor my battery %. I have "calibrated" the battery by using the phone until it shuts it self off then charging it to 100% while its off then unplug it and turn it on and then plugging it back in.
Usually i will get between 15-19+ hours on normal use if i unplug it and plug it back up when it drops suddenly to 9-% in the mornings but if i dont ill get somewhere around 13 hours of life. is there something wrong with the phone, battery or charger?

I want to change the battery charging animation that lights up when the phone is charged while it is still switched-off. I have installed the "BAC lite" to change the boot animation. however, it does not support the change of battery animation.
Looking for path of the system file/folder which must be modded to change the animation? I am using Spice MI 270 (Chinese Model no. MT6516). The android version running on it is Froyo (2.2.1).

I've noticed that when charging my phone overnight, the light will turn green like it is fully charged, but if I unplug it, and plug it back in the light is red again and can take 10-20 minutes to turn green again. It seems the phone doesn't agree with what it considers for the battery to be fully charged. Anyone else have this issue? Is it a software thing?

I recently noticed my Incredible 2 was only showing the battery life to be 50% after charging it overnight. I switched AC chargers and the problem continued. So I figured the battery was done, for whatever reason, and I ordered a replacement battery from Verizon directly. The replacement battery also only charged to 50% after a full night's charge. So...it's probably an issue with the phone itself. I have Total Equipment Coverage but getting a new phone's a hassle and I like my Incredible 2 (not guaranteed to get another I imagine). I figure it might be the phone's "charging circuitry"...is that easily repairable? I need to have a fully-charging phone in a week or so...

I recently got a new Samsung gt-i9100 smartphone I had it updated and rooted to the XXLPS ICS 4.0.3 Firmware.
I have problem that the phone charges very slow like ~12% per hour with both the PC USB cable and the original wall charger.
I know that the phone supposed to charge very slow in USB mode however I've noticed that even when charging trough the wall charger the phone still charges in USB mode. (I can see it in the phone status menu)
My question is: Is there there really another charging mode (shown in phone status) when charging trough the wall charger?
I did factory reset and wiped data but the problem still exists.
