Has anyone experienced this issue? No matter how long I leave it on the charger, I've never seen it reach 100%. The most it got to was 99%. Thanks in advance!

Re: Extended battery not charging to 100%
1) does your screen need to be brighter than the sun (for me right now yes lol)
2) wifi when you can as 4G is a killer
3) are you just Nexus happy and using your new toy 3 times more than your old phone (for me right now yes lol)

Re: Extended battery not charging to 100%
You have to discharge it a few times before it get to 100%. All batteries has this behavior.
By the way, my wifes nexus battery life is pretty insane. Flat line at night due to no usage with email.sycn turned off. Over 23 hrs on one charge.

Thanks for the stats - looking forward to my extended battery arriving. Im getting close to 17 hrs on standard with my usage so the extra 300mAh will be nice!

Re: Extended battery not charging to 100%
I have the extended and it takes for ever to charge this battery. Both nights I have put it on the charger @ 14%. The 1st night it took 9 hrs to get to 100% last night it took 8hrs. I hope this gets better.

how is her android OS usage % so low.. mine is like mid 20's and so is a lot of peoples. i think that is causing battery drain issues.
but yea, i charged my battery all night and it showed 99% on the lock screen. i shut it off, let it charge for like 5 minutes and turned it back on. it finally went to 100%. this is the second time i fully charged it and saw this

Re: Extended battery not charging to 100%
are you charging through the computer or the wall? charging it through the computer is hella slow the wall charger is pretty quick only takes a couple hours for me

O have read that all phones show 100% even though they only charge to 90 or something like that. Which is why they drop the percent so fast at the end of a charge.

Re: Extended battery not charging to 100%
Not true. Every Android phone besides this one, charged up and said 100%. I notice this one only does 99% most of the time. Nothing a root and battery stats sweep cant fix.

Man if 8 hours is forever the 2 month wait from when the phone was announced to the released must have been brutal for you
I had that issue with the rezound, but I found it to be the charger issue. Replaced the charger and it started charging to a 100%

Ha I just 2nd cycled my GN after its first day with light use got me around 17 hours. I was shocked when after 8 minutes the battery went down from 100 to 90%. Ill try bump charging now see what happens.
I followed this process the first day I got it and it's been showing 100% each morning since then. Not really sure if it makes any difference during the day, but can't hurt.
Modern Li-Ion batteries do not have a memory and do not need to be conditioned, but Android needs to be taught exactly what a full charge represents so that it can manage power appropriately.
One of the things I recommend all new phone owners to do is to perform a deep power cycle.
Let your phone discharge completely, keep it on until you are warned about low battery and then just let it run out. Most phone will shut down automatically around 5%.
Plug the phone into the original a/c charger, not the usb cable. Let it charge to full uninterrupted.
When the phone says full, unplug the phone from the charge and reboot. Once the phone is completely restarted, plug it back into the charger and shut the phone off. Even if it says fully charged, let it charge for at least one more hour.
Unplug the charger and reboot the phone one more time. Now you should start seeing (possibly significantly) longer charge times.
Without a deep power cycle, it doesn't know the true capacity of the battery. Be advised that you should only need to do this once as regularly deep cycling the battery can harm it. Li-Ion batteries perform better and last longer with incremental charges.

For what it's worth, and this may or may not be the case with the Galaxy Nexus but, Samsung is known for using a practice with their phones of never charging to 100%.
My old (so sad to say that) Nexus S 4G only hit 96% without a custom kernel that specifically changed that setting.
The logic behind it is that charging to 100% and then trickle charging after that does damage to the battery and reduced it's overall life. Meaning the battery needed to be replaced sooner. You've seen where a battery hold a charge for an entire day when you get it, but in a year you need to charge mid day. That's what they are trying to reduce.
Instead Samsung charges to about 96-99% (varies by phone) and then cuts the power. Then when the phone discharges to say 94%, in the case of the Nexus S, it'll start charging again.
Again, not sure if that's what's happening here but the Nexus S is also a Samsung device and it's known to use this practice so I think it's a safe bet to assume that's the case with the Galaxy Nexus.
I wouldn't sweat it guys, crappy battery life is because of the large screen and LTE radio, getting another 1 or 2% of battery isn't going to really help that much. There will probably be custom kernels released that disable this if you do care that much.

Tried bump charging, got it to legitimately 100%, it didn't almost instantly go down to 90% which is awesome.
