I have seen a few people say they have noticed slow charging with the Nexus 7. I'm not sure if the following means anything, but here is what I have noticed between the two N7's that I have and the one that my brother owns.
My brothers 16GB N7 (purchased 2-3 weeks ago) is extremely slow charging from both the wall and USB power sources Using the OEM cable, and after market, and when trying an iPad wall adapter. No matter what, it's just SLOW.
I purchased a 32GB about a week ago, and have noticed that, while still slow compared to my iPad 3 and iPhone 5, it charges faster than my brothers, so we set them side by side @ 40% and while I should have recorded the time, mine had reached 87 % while his was only at 80%.
A few days ago I realized that while ai sit on the train so much that having celular would probably be a better idea and I missed having it on the iPad which I had sold to buy the N7(aside from missing LTE I do not regret this move one bit). So I sold the 32GB to a friend and bought the 32 W/ 3G. This one though charges noticeably faster than even the last 32GB did. I am running the same kernel and a CM branded ROM, but it doesn't seem to suffer from the slow charging as much, still not iPad3 recharge speed though.
I am wondering if Google/ASUS are changing firmware on different revisions to fix this issue as I see no other reason for the charging speeds to be so different.
** On a side note while my brothers 16GB had no screen lift, my 32GB had lift. I opened it and found that, while face down on the table, the top right screw was 2/3 unscrewed and while tightening it I saw that the screw about an inch or so down from it for the screen was missing all together. Luckily my 3G doesn't have any lift, at least not that I have noticed yet.
I think I saw something straight from a google higher up mentioned to developers that a different power controller would be implemented as a hardware revision on later n7s. I would assume most if not all 3g models are using this new power controller.

My 3G 32GB charges pretty fast .. quicker than the 16GB that is for sure .
i had a seven that was replaced recently, 16gb, because it stopped charging. that seven always charged slow. the replacement seven, also 16gb, charges much faster than the older one. same charger/usb used on both devices.
The stock Asus charger has always been slow to charge my C9O 16GB N7. Using my TouchPad charger instead the N7 charges significantly faster. The Asus charger has since been relegated to charging phones.

My nexus 7 used to charge fairly quickly, around 90 minutes from zero to full. But recently I plugged it in and after an hour it was not charging at all. I unplugged the cable and it looked a little charred, and the socket itself had a slight burning smell. I've used the official charger only, but I think something has gone wrong, it note takes hours to reach a full charge, so think I need to return mine.

Mine was connected to the socket about eight hours while I was asleep since yesterday (when I got it). It charged only from 25% to about 80%, though I remember the screen was lit up, and I turned it off some time during the night.
When I was in stock ROM it was fast but now on paranoid android 2.54 it's very slow.....

My C80K is picky about what chargers I use with it. It's fine and quick with the Asus charger that came with it, and the Samsung charger that came with my phone, but doesn't charge very quickly on my mom's Motorola charger (still reasonable though) and takes 10+ hours to charge fully on a generic charger I bought at Five Below (which is ridiculous). It charges off the USB ports on my computer slower than the Asus and Samsung chargers. I still use the generic charger for my phone though, and it works fine.
Please, define slow in minutes/hours and if not using the original Asus charger, also mention the output current, which the 3rd party gives. Otherwise it just talking . Asus charher is 10W, whereas a phone charger is usually below 5W - it is normal to charge slow.

I have noticed that charging is slow with mine (32gb model). It will normally take around 6-7 hours from around 10% battery life to be fully recharged. I have also noticed that the device will not charge when in graphically intensive apps e.g games. In fact, it will slowly decrease.

I got mine from digigood, so it came with an original US charger (I'm in UK) and digigood supplied a universal microUSB charger.
I've not timed it, but a full charge from empty takes approx. 3 and a half to 4 hours. Someone in this thread said theirs took 90 minutes... I also have a blackberry charger which is micro usb, and I have an OEM galaxy s3 charger too. I think I'll time each from empty and see what happens.

I'm on my 3rd n7 (got 16gb at release, then 32 when it came out, then got a replacement for that as the screen had a few dead pixels). The 16gb is very picky about the charging cable, using the stock cable it charges quite quick (maybe slightly slower than the 32) but using an extension with the stock cable the power actually falls very very slowly, and an overnight charge only adds about 50%
The 32 however, is lightning fast, a full charge only takes about 3hours. I can put it on charge for 20 minutes and get about 20-30% charge.

Weird I have a 16 gig and it charges fast 15-80% in about 30 minutes hell even my car charger for my phone will keep it fully charged while running wifi and gps doing navigation

N7 32GB charges faster than N7 16GB?? I'm interested... how about some absolute numbers like this?

Above is using the standard Asus charger and cable.
My N7 16GB charges slowly if using my Motorola DroidX charger and cable.

Huh????? My 32 N7 takes 4 hours to o charge.....
For reference, mine took ~5 hrs to charge fully from 0 to 100. Nexus 7 32G WiFi.
Using wall charger. 2A current.
I just took my 16 gig off the charger put it on at 14% 30 minutes ago and it is sitting at 56% now mine is only a couple weeks old
Mine is a c80 I was reading they can have the new power management chip

Can we get (Fast Charge) to work on the N7 like they have working on the GN? I love it on my GN.
I know fast charge is for pc usb charging only.
Last night mine was completely dead. Plugged in the supplied charger at 10pm. Battery is now 97% after 7.5 hours

So this makes little sense to me, but I have found that using the charging block from my note 3 (not adaptive fast charging) gives me way better battery life than if using the note 4's block with fast charging enabled.
My phone lasts about 7 hours after charging to 100% with the N4 charger but well over 16 hours after charging to 100% with the n3 charger.
Anyone else getting this phenomena?

Wow! I don't have an old charger but will test non fast charge and see what I get.

do you get the same results when using the stock charger but disabling fast charging in settings?
Still testing. Only been awake a few hours and just recently unplugged

I use a mix of wireless, fast charging, car fast charging, and a Motorola wall charger. Have not noticed any difference. I change batteries to new ones at 6 months as well. Maybe a battery going bad?

No updates?
So, I exchanged my explodey note 7 for a non-explodey one.
I'm now having an issue with fast charging. With the old note 7 I would leave a game running while connected to the fast charger (samsung) and would gain percent fairly quickly.
Since the exchange, the phone holds steady and gains a percent every 30 minutes or so. If I disable quick charging I begin to gain percent at a reasonable rate. Not as fast as the old note 7 with quick charging, but notably faster than with quick charge enabled.
Is anyone else experiencing this issue?
I having Problems with my phone charging. it can take up to 7 hr to fully charge when dead. @ 60 % it takes 55 min to charge just 40 %. Not sure what's going on with my new replacement phone.
They change the rates. Slow it down a bit. They dont want another battery recall. So there taking steps.
I find it that if i charge while on it take long, but off it work as my old note 7
I have the same problem .. when I'm using Viber app and charging doesn't charge I was a 48% after a 20 minutes I was at 47% so I'm really worry about it I hope is not a big problem

Yup, for me while the screen is on it charges like regular . Only after the screen is off does it fast charge and even then it's inconsistent. Had to get the coral blue instead of my black because they were out of exchanges and now this charging ish. Makes me feel like I should have kept my old one
i have nokia 7 plus and for couple of weeks i use the 1.5 amp charger ...
the screen usage of using my phone is between 4 to 5 hours use no gaming...
after that i tried the original 3 amp fast charger and the usage increase to 8 hours of use after a day recharge by orginal its come back to first 4 to 5 hours...
i scratched the cable ..in 1 direction it is not fast when i reverse it switched fast charge
i think its software issue about liying the percentage of charge and shown the 100% battery when it's 70%
i repair mobiles for 5 years and i use a lot of phones but i don't see phone like this with this battery.
comments your battery usage and send pictures...
Hi!
I'm a bit annoyed about the charging speed of the Pixel 7.
Tested with a bunch of chargers and cables and charging is not going 15-16w.
Pixel 6 was charging with up to 21w with the same hardware.
Anyone having the situation?
The Pixel 7 does not charge very fast, yes. I got the original charger from the Google Store (for 30€) and it takes ca. 1,5h to charge the device from 5% to 100%. It won't get any faster I guess. Not every USB PD charger supports PPS, keep that in mind and buy only chargers that fully work for the Pixel 7.
All the chargers and cables I'm using are capable and we're charging the Pixel 6 up to 21W and the Pixel 7 is specified just like the Pixel 6 so i assume my one is kind of faulty
Understand that best practice is to:
1. Use low power charging
2. Charge up to 80%
3. Do not allow the batt to fall below 30%
This will help with battery durability.
Just my 2 cents.
Yes, but when you're on a bike packing trip in race mode you need a fast charging phone.
Beside that, I'm also pissed that devices don't fulfill their own specs
