How long does it takes to charge the CDMA GNex?

It seems like I've been downloading this phone for more than 3 hours,does it take that long? I put the phone on the charger and it had 10% left and its still charging,Is that normal?

takes me about 1.5-2 hrs

When I use the Samsung charger, it will charge from 20% to 90% in less than an hour

I took a nap for 3 hours. My phone was nearly dead and when I woke up it was fully charged.
Just as fast as my previous level iPhone 4.

T-Mobile Terrible Battery Life

Hi everyone I got my phone 4 days ago and have been through charge cycles but my battery life sucks. I only get a Max of 2hrs on screen time and 12 hours with the phone on (if its in airplane mode the whole time). Also, it takes forever to charge. I charged it from 7pm to 10:30pm and it went from 2% to 34%. And as i type this message (on wifi) I lost 3% battery life. What should I do?

Also it seems that display takes up 50% battery (which is good) but as soon as I send one text, phone immediately goes to 50% and display down to 18%. It stays that way all day and rebooting does not help. And the battery percent goes up and down without charging. And yes I have calibrated it multiple times

Have you considered getting another battery

I would not like to spend anymore money on this phone if possible. I just spent $680 on it. What kind of battery life are u getting?
Sent from my SGH-T999 using xda premium

You should return it. My on screen time is 3hrs and I still have 61% left.
Sent from my SGH-T999 using xda app-developers app

Yup, I can get 4+ hours screen time, not on power saver. You need to swap your phone out, something's not right.

Something is definitely wrong. I had a 45 minute conversation in my car today with the screen on for navigation and it only drained 15%. I was quite impressed.

Call up T-Mobile and tell them your battery is defective and they will send you a new one free of charge. Plus you can keep your old one.

Well I went back to the tmobile store and just swapped the phone. Hopefully this one will be better than the last.

Most likely, you have a lemon, and you should exchange it.

keep in mind, if you store your phone in a hot place it will drain considerably quicker..happen to my S2

are you serious? can someone verify this?

Do you have low signal. At my home I had the same issue, but on sprint. Using something like juice defender extended my battery life considerably.

Then they'll start charging. My friends Sensation legit needed a back cover for his phone (power button was shot and volume rocker fell out) but he couldn't get one from HTC after three attempts.

Try doing a factory reset. It helped on my S3.

If Your phone is running battery intensive apps its gunna take longer to charge. For instance...if I'm running navigation with music and the screen is on high brightness I will still LOSE power while I'm charging on my trucks USB.

Something wrong with your charger. Try another charger, if it charges ok with another charger then obviously your charger is at fault. Get a replacement from Samsung.

Thanks mate..will try that

Make sure you use the charger provided. The note 2 uses 2mA. Most phones use 1mA.

Make sure you are using the same cable as provided. One time I changed to a different and longer cable and it took forever to charge.
Sent from my GT-N7100 using xda premium

+1, the longer cable also not able to withstand charge while using the phone...

How long does it take for a full charge? [Culprit: Bad USB cable]

Well I need to know from you guys, it's not that I don't know, but need to reconfirm. I think mine is taking much lower now than it was. A full charge, say from 5% to 100%, with Stock charger?
Thanks in adv.
Sent from my GT-N7100 using Tapatalk 2

roughly 1 percent for 1 minute. should be charged in a couple of hours

~2h30
Sent from my GT-N7100 using xda app-developers app

Charging from 0 to 90% happens in no more that 2 hours I would say. from 90% to 100% the charging rate gets slowed a lot. So basically shouldn't take more than 2:30 hours from 0 to 100%.

Thanks guys. Now I remember it was 2 hours 45 mins for me too at first.
Today it took 4 hrs 30 mins. Reason? I'll say tomorrow, after confirming.
Jeez PowerAMP!

I rarely charge it to 100%, usually to 70 or 80%. much better for the battery in the long term

Any research or refrence for this longevity ? I heard its always better to charge 100% ?

Thanks man ! Really helpful article...
Sent from my GT-N7100 using xda app-developers app

you are welcome. the general rule is to try to 1) avoid charging to 100%, really diminishing return the higher it goes; and 2) avoid deep discharge cycle. I usually use 40% of the capacity at work everyday, so charge to ~70% in the morning, use down to ~30% and then charge again. charging time in this range is rather linear, about 1 percent a minute

Yeah, it happened to mine too few days back. My Note2 went crazy, taking around 7-8 hrs to fully charge from 15%. So, i tried searching about the problem on google but to no avail. Did a factory reset with cache wipe and problem solved :good:. Now it takes about 2.5 hrs to fully charge from say 10% (using the samsung wall charger with phone switched on). I can only say that the slow charging was caused due to some software but don't know exactly which one? You may as well try the hard reset if anything else doesn't work out .
P.S : Btw i'm on stock fw with no root or mod! Only did some OTA updates couple of weeks ago.

Guys, we have a changeable battery and is already writed Inside to android that it won't charge to 100%, it just shows at 100% but really it is at 95%-98% that feature came with 2.2.1 update 2yrs ago.
And we can change the battery after 2yrs for 20-30$, unlike Nokia lumia users or HTC one x or iPhone users.

Yeah, thanks. But if you've Watchdog installed then you can see which app is going over threshold and keep running on background. And yes, this time, again, the culprit was PowerAMP! Uninstalled it and voila. The same app created problem for me when I had my S2, charging was pathetically slow, even I had to go to SC and they said battery is gone. But I didn't believe and asked a techy friend and he said it might be some app, and damn right he was.
Anyway, if anyone having the same issue like mine, that is, charging duration has increased with Stock charger, then install Watchdog (the lite version will do) and see who is the culprit.
I have no idea how a top app like PowerAMP could cause this! Jeez!

The same problem happen to me few days ago..during that that i was charging using extension cable where 3 pin plug is sharing with my note 2, laptop n tablet charging @ the same time..its take nearly 4 hour for fully charge the note 2 while im using n charging my laptop n tablet..but, from that i understand that when the connection all charging at the same time on the same 3 pin plug, the load are higher which decrease the current value (current drop)..that the reason why my note 2 charging slow..check if OP case is same like me??

Is this long-charging-time problem a single occurrence or you are consistently having this problem?

[Q] Faulty unit?

Hello everyone,
I just bought a new LG gpad and the battery is awful.
Browsing webpages gives me about 3/4 hours of lifespan but the worst part happend tonight
I had 32% battery left and decided to switch off the unit completely, when I turned on the pad this morning there was no battery left at all
I believe this unit is faulty or is normal to consume battery when switched off (not sleeping)
Do you experience the same?
Thank you.

When my tablet is off, I don't lose a single percentage point over night.
Maybe you need to return yours.

Battery isn't amazing but its pretty darn good with screen at 60% and under clocked to 1100mhz. I can get a days use out of it and no loss of charge overnight.
Yeah, yours sounds wrecked.
