Fully charged indicator? - Nexus 7 Q&A, Help & Troubleshooting

Sorry if it was asked before.
I see that the battery is 100%, but there is no indication that it's fully charged.
I still see the charging indicator.
Is it OK?
Thanks!

If you're worried about "over charging", don't worry about it, just leave it plugged in.
Otherwise, yes, it indicates "charged" on the lock screen when it's completely charged.

I searched but couldn't seem to find an answer. My new N7 is charging up while off. When I plugged in the charger the screen showed an icon showing it was charging.....then went off. When the unit is fully charged will an icon come on screen to show it is fully charged....and will it stay onscreen with the unit powered off?

With the N7 powered down, when the charging is complete, there is no icon to tell you it is fully charged. You have to depress the power button to see if it is fully charged.

battery charging question

how do you tell if your phone is fully charged when charging the x1 beside looking at the battery status when the phone is on. does the illumination light go out when your unit is charged or does it continue blinking whether its fully charged or not.
when i charge mine, the lights blink and then after several hours, i would not see it blink for a little while but then every now and then, i would see it blinking again.
just want to know if the lights stops blinking, the phone is fully charged.
Exactly what I want to know.
Yes, the side lights stop blinking when it is fully charged.
When it stops charging, the lights go out. But then, when in trickle charging mode, it is shown by the light.
how can I see the remaining battery (percentage) without pressing a series of buttons?

You can set the clock in the menubar to show the battery power, but the the clock is gone or you use a small and nice freeware like batti: http://code.google.com/p/batti/

thanks, that makes a lot of sense now that you pointed it out.

Battery level drops to 99%

Anyone out there notice that on a completely full charge using the AC charger, the minute you pull out the charger, the batt indicator on the TAB will drop to 99% ? The 100% only last a couple of seconds!!! No apps running , wifi, BT, GSM is all off.
Is this normal ?
Yup. Same thing happens here. I think it's normal. Same thing happens with my mobile phone.
Thanks.. but this never happens to my mobile phones and that includes Samsung Omnia, Omnia II and Omnia Pro..
As soon as i pull my plug i am showing 98%.
Yep, I was wondering that too. It goes straight to 99%. I guess it's some bug, it doesn't really go to 99%
It's just rounding down, but think about it:
The moment you unplug it, you're consuming battery power.
If you've consumed any battery power, it can't be at 100%, now can it?
I really don't see the problem with it dropping to 99% .. really i don't !!

Any number of ways, but I have been using the "Batterylife" widget from curve fish on the market.
Thanks i installed it. I noticed that my battery drains quiet quickly, my tab was in stand by mode for 30 to 45 min and i battery drains by 9%. I just bought it this afternoon could please guide.

With a lot of android devices the battery is not calibrated with the system, there was a post on how to do this with a nexus one. i used it on my vibrant and it worked the same. it was a series of steps like plugging the phone in, powering off, powering on, unplugging again, weird stuff like that. and it actually works. sorry i dont know where the post is or the exact steps to do.

I did this for my captivate and works well:
1. Connect the phone to the charger with the phone powered on, and allow the phone to charge until it shows 100%
2. Disconnect the phone from the charger, and power it off.
3. Reconnect the phone to the charger with the phone powered off, and allow the phone to charge until the battery indicator shows 100% (you can use vol-up/vol-down to make the indicator come back up when the screen goes to sleep).
4. Disconnect the phone from the charger and power it on.
5. Once the phone is powered completely on, power it off again and reconnect it to the charger until the battery indicator shows 100%.
6. Disconnect the phone, power it on, and use it.
Hey, it doesn't happen to me so you must have something else going on.
The only thing that matters is how long the battery lasts between charges.
The percentage of charge shown on a battery gauge widget is meaningless unless the battery is draining abnormally in relationship to the way the tab is being used.
I find that my tab drains from 99% to 60% in about 2.5 hours with wifi on, GPS on, bluetooth off. It then takes another 4.5 hours or so to drop from 60% to about 10% under the same conditions. So... 7 hours of continous wifi on web browsing isn't much to complain about.

exactly..
Most modern electronic devices on Li-ion batteries do this. When the device reaches 100%, it will stop charging to prevent damage to the battery. The battery then drains to 90-95% and the charging circuit allows the battery to charge again. Most systems hide this by displaying the battery level at 100 or 99% for a while after the device is unplugged. Hope this helps!

Charging fails until reboot?

When running n163, my charger (twice) stopped working until I rebooted. The odd symptom was that the "n" was green, right down to a low-battery shutdown, even when the USB end of the cable was unplugged.
The NC itself acted as if the cable was unplugged, even when plugged into a USB port.
It hasn't happened under n165, but that's only since this morning.
These were some USB changes recently, weren't there?
Thanks!

It happened to me again just now. I'm running n177 now, and I'd been using my NC off and on the charger all morning. I plugged in with the gauge at about half, the plug light went green, and I got no lightning bolt on the gauge.
A reboot restored normal charging.

Same cable works fine after reboot, didn't even unplug it for the reboot. The light changed color midway through the boot.

I had this happen to me too. Put it on the charger last night right before I went to bed. Woke up to a green 'n' but the battery was down 6%. Unplugged & replugged the charger, still a green 'n' but not charging. Reboot got an orange 'n' and it's finally charging.
Running Nightly 174.
I am seeing a bit of bizarre behavior with Nightly 166. On two units, when I power down, and plug in the charging cord, the unit boots up. I have had to press the power button to get the screen to go dark, and it will charge faster than if I had not done so.
Also, I have experienced once or twice, an issue of putting the unit under charge only to have the charge level reported as low, but, strangely, it felt like the unit was warm, like the battery had undergone charging.
A friend's Nook with 166, he claimed when he put the unit on a charge, it kept cycling screen on/off. He was using a non-OEM cable, but the proper AC adapter.
Does the unit have to wake itself? Does the OS assist in charging the device? Is there a known issue with %Charge being displayed?
I had Nightly 177 loaded but backed it out because the Market wasn't working.

That's normal behavior. Something about preventing Sleep of Death.

Can't trust non-OEM cables; there're extra conductors in the B&N cable for faster charging.

Yes; look for PBD, Premature Battery Death.
Turning USB host mode on and off affects my problem, but it doesn't help it any.

Sounds like the same issue. I find that if it's unplugged when I boot, it just doesn't charge, and the NC never notices when I insert or remove the charger cable, the lightning bolt never changes. Also, I've lost USB storage mode altogether, a real pain.
Sent from my NookColor using xda premium
Well, it turns out that this whole problem was the charge cable. I had satisfied myself that it wasn't the cable with a visit to the store earlier, but I think that was before I realized that the "plugged in" state never changed after boot.
The fact that the plug could make the NC itself so confused about the state of the power supply is really startling. By the end, the light on the cable was changing color when I powered up.

Battery Status Wonky....
Ok. Reading through this I seem to have a similar but not identical situation.
Running CyanogenMod-7-08312011-Nightly-encore with kernel 2.6.32.9.
Nothing special about the install.
Few days ago Nook took a nap and didn't wake up. Thought it was bricked but after fussing with a combination of pressing power and the "N" button finally got it to boot up like if nothing had happened.
Problem? When the battery started to discharge after its nap of death it got to 16% and stopped. Doesn't move. Perpetually at 16%.
If I plug it is to charge it the bottom gets warm, status says it is charging and the cable changes color like it is supposed to, (orange to green), just like it were fully charged but the Battery Status stays at 16%.
Bought a new cable from B&N and same thing. Battery Status stuck at 16%. Nook feels warm, (as if battery has been charged), and the cable changes color correctly, (orange to green).
At one point I even took the cable out and the status indicator showed that the battery was still being charged but no change from the 16%.
Very annoying as I keep getting notifications that I need to recharge since the battery is at 16% but I can leave it on for HOURS and it keeps working fine.
Any ideas or should I reformat to stock and get a new one from B&N?

That sounds like classic Sleep of Death, and is most likely unrelated.

At this point, I trust the cable light over the software to reflect reality, but mine would change color as I wiggled it because it was flaking out.

Did you power-cycle while plugged in? I did several boot-to-CWR while fiddling with things, and wound up with not enough power to boot when I got to the store. Try full power down, insert new cable, power up. I'm pretty sure that the software has a role in this.

What's reporting 16%? Battery monitor and the status bar (just the icon) both reported consistent levels throughout, except for being always plugged in.

Okay. Decided to try and discharge this puppy completely and they let it charge all the way up again and see what the Battery Status indicators look like.
As of right now, (12:24 am on Wednesday 9/14/2011), my Nook has been on since boot for 7:22:14 and the Battery Voltage still shows 3613 mV with a Battery Level of 16%.
BTW Battery Temp is 27.8 C and Battery Status shows as Discharging.
How long this sucker is going to last is anyone's guess. Hopefully by tomorrow it will be dead and I can start charging it to see if the battery status goes back to normal.

Red light of death after Antutu Benchmark

The title pretty much explains it.
My N4 died on me today after running an Antutu Benchmark. I was running on Android 4.4 with the latest Fauxkernel (v29).
I can't boot it up anymore without the charging cable plugged in. When the charging cable is plugged in, the LED flashes red once, the display turns on and shows me the battery charging indicator and turns off just a couple seconds later also with the LED flashing red once. If I attempt to turn it on, the Google sign appears but the phone turns off immediately after that and once again, say Hi! to the red LED.
Pretty much tried everything so far, charging my battery, getting into the recovery menu, pushing down the power+VOL Up buttons for 60 seconds, etc. Nothing helped.
Maybe you guys know any way to fix it? I don't wanna open my device nor replace the battery if possible.
Thanks in advance.
2 ways to fix it. first, leave your phone on the charger for 3-4 hours. thwn try to boot it into the bootloader and press turn off the phone. let it charge further. if that doesnt work, remove the back cover, remove the battery, then clip the battery back in. the second method works 100%.

I can get into the bootloader but once I select power off, the phone just turns on again and shows me the battery charging indicator. Not sure if it's supposed to be like that but the indicator is completely filled so that would probably mean the battery is full.
Not sure if I have the right screwdrivers to open the back.

the reason for rlod is that the phone thinks that it is under 0% battery. leave it on the indicator that is filled, thats a good start. when that filled indicator starts the reguler behavior that it looks like its filling(up and down), thats when your phone will be fixed. leave it charging for a few hours.

Alright, I'll try that out. It's kinda annoying though that the display turns on every few seconds and turns off again but if it's going to work later that'll be worth it. Thanks alot!
if worst comes to worst, remove the battery and plug the battery back in. this will "reset" the battery(like a normal battery pull for devices with a removable battery).
seems the post may drive users a mis-understanding to AnTuTu Benchmark, I will ask our engineer to double check.

Oneplus 5 battery error. I need help...

Have a nice day. I have Oneplus 5 phones. While playing with the phone, the battery ran out and turned off. Then I tried to turn it on several times by pressing the power button but it didn't turn on. In my last press, a screen came and went 'battery low' and something Chinese came out. Then it closed again. Then I overcharged the team, but no more charging half a day barely enough. What is the reason? How can I fix? Can you help me, please?
From a Google search;
Discharge your phone fully until it turns itself off.
Turn it on again and let it turn itself off.
Plug your phone into a charger and, without turning it on, let it charge until the on-screen or LED indicator says 100 percent.
Unplug your charger.
Turn your phone on. ...
Unplug your phone and restart it.
Should I use the original charging adapter?

That would be wise i presume, but the OP is not very picky about chargers like an Apple is. But for me i would certainly want the quickcharge function as it saves some time

1. I will fully discharge the phone. 2. I will try to turn the phone back on. If it opens, I'il wait until it closes again. 3. I will charge the phone. 4. When it's 100, I'il unplug it and restart the phone. Are the steps correct?
Actually, I didn't understand the last sentence you wrote.
