Nexus 7 (2nd gen)= OMG the screen is amazing!

[ChronoReverse]

Exactly. All my devices are plugged in near my power ranger night light during bed time.

Even easier with my Touchpad, it sits on the wireless charging stand when not in use. The idle drain is poor but neatly negated most of the time.

I don't touch my tablet every day so I don't want to leave it plugged in that long. Scared of over charging it and slowly ruining the battery. And this of course is the problem. If I'm leaving it off the charger and pick it up in three days, it's usually dead or nearly there.

 

[ChronoReverse]

Unless it's a terrible piece of junk, your tablet and its battery will have power circuitry that prevents overcharging.

Sometimes people report "my battery dropped from 100% super fast when I took it off the charger" but that was only because the power circuitry disconnected the battery after it was fully charged and left the power meter at 100% (so people wouldn't think OMG my phone isn't charging).

 

[Suspicious-Teach8788]

Does nobody else plug in their device to recharge at night? I find it annoying to use a tablet while plugged into a charger, so recharging over night is the perfect time. Why 100% idle power usage is such a big issue, I have no idea.

I recharge my phone, but why recharge my tablet every night? Given how the iPad is setup, you can go a week or two just having it lie around, and pick it up another night and finish an episode of The Office. That shows how good the damn battery is. I don't ever remember my gf charging her iPad save 1 or 2 times, and it's always been at her disposal whether its waking up and reading some email or using it as a recipe book. I complained about this during the TouchPad era and then people said why not charge?

Well now with the Nexus tablets being decent I can leave mine around for a week or so and pick it up for a road trip and not worry about battery. The fact is once you get your devices setup so that they only sip battery, you'll love it. Why do I need 2 USB cables for my phone and my tablet EVERY night?

I absolutely love the Touchstone charger for the Touchpad. No charging cords to plug in and worry about. It sits on the charging stand when not in use and makes for a perfect clock. I have 9 tablets around the house. If one is dead, I simply pick up another. If you only have one tablet, it's not hard to keep it charged. It's when you have multiple tablets that you might forget to charge one. But in that situation, you can simply grab another. People want to make a big deal out of non issue.

Good question.

I'd be interested to see how much juice it looses in a 24 hour period. I am considering this tablet but because of the poor standby life of Android tablets, I am currently waiting for an iPad Mini with retena.

Ok here's my results. Screen only turned on to check battery life (6 times total):


Aug 12

Unplugged n7 at 5:47 pm
100% charge

Aug13

12:30am
99% charge
11:31am- 94%
3:05pm - 93%
7:01pm -92%
11:12pm - 86%


So, in ~ 30.5 h it lost 14% charge. This is with wifi on, etc.*
in 24 h it lost only 8%

For some reason Google+ is going nuts with battery usage on my Nexus 7 FHD. I didn't touch my tablet at all today and in 13 hours it went from 100% to 80% and it seems to be all Google+. It totaled over 4 hours of keep awake time.

Not sure why Google+ waking up the tablet so much. I have Google+ on my Nexus 4 and it doesn't even show up in my battery stats at all on my phone. The settings appear to be identical, same notification settings, the only difference I saw was integrate with contacts was enabled on the Nexus 7, but not the Nexus 4. But I don't think that would be keeping the tablet awake all the time.

I might have to uninstall Google+ from my Nexus 7 FHD if this keeps up. I'm curious is it just me or does Google need to update Google+ for the Nexus 7 FHD?

New Nexus 7 is having lot of issues with their screen.. people are reporting problem that screen is behaving abnormal, auto-touch issues...

Thank you jiffylube for your testing.

I've since set my tablet to turn wifi off during sleep and seems that I got my drain down to about 15% per day which is a decrease about 50% with wifi enabled.

 

[lopri]

If you don't install anything and run anything, Android device can retain battery like forever. I have a Chinese iPhone mock-up that I picked up for $100 that I haven't gotten a chance to get rid of. It has no SIM and runs Android 4.0, and only connected to Wi-Fi. And it reports wildly incorrect battery stats. No Google Play, weird ROM with Chinese and English mixed up, so basically it just sits in the corner.

But nearly one month after a full charge it still turned on and told me it still got 30% of juice. I didn't believe that number but the fact that it still turned on obviously means there was some power left. So power usage is all about what apps you install and what you do with them. Issues arise because apps are not properly coded (incompetent devs) and they do things that you don't want them to or you have no knowledge of.

My retired Nexus S still acts as my alarm clock and PMP. I can leave it on for a month in airplane mode and it'll still be going strong. With wifi on, it doesn't last as long but a couple weeks isn't unreasonable.

I love my 2012 Nexus 7, particularly since the 4.3 update, but I hate how long it takes to charge. Since the 2013 model includes a Snapdragon processor, I'm assuming that it supports Qualcomm's Quick Charge, but I can't verify that. How quickly does the new 7 charge compared to the old one?

Other than that, has anyone noticed degraded sound quality/buzzing as they decrease volume on the new model? It was something mentioned elsewhere on these forums, if memory serves. Here's what I'm talking about: Static / buzzing from speakers at low volumes - xda-developers

It's because the Nexus 7 uses a crappy digital volume control that simply reduces the volume of the digital waveform before it hits the DAC, instead of having a real analog volume control -an op-amp that adjusts the volume of the signal before it hits the headphone/speaker amplifier.

What you're hearing is quantization noise as at the lowest volume the audio uses only 2-4 bits of dynamic range instead of the full 16 (or 24, dunno what DAC is in this thing). It's the same as the bit-crushing effect you hear in some dubstep and other electronic music that degrades the audio into a robotic crunchy mess, only here it's not on purpose, it's just cheap design.

There is nothing you can do about it.

 

[openwheel]

coming from a audiophile like myself who is anal about sound quality, the new Nexus 7 performs fine. The speakers do get loud, but like all tiny speakers, they all sound like crap to me. At low volumes there is no "static" noise that my ears can distinguish. The headphone out drives my Etymotics well for travel purpose.

Overall, I'd give the new Nexus 7 a B+ for headphone output, and B for its stereo speakers. (For comparason, I would give iPhone 5 A- for headphone output and C+ for its speaker).

Considering that most devices use similar amounts of idle power, why are people trying to compare an iPad (11,560mAh battery pack), to a Nexus 7 (4,325mAh battery pack).

If all things were equal, the iPad would still leverage 275% more idle standby time, simply because its a far larger device with a far larger battery. Remember the Nexus 7 goes in my back pocket. The iPad goes in the backpack.

Anyways, my 2012 Nexus is generally used 5 days at a time, between recharges. And when I left it home during a business trip, the tablet still had 30% battery life when I came home 18 days later, and that was while it was doing nightly Titanium backups (and happened to update about 50 apps during that time.. yeah, I have a lot of apps.)

Anyways, the same thing seems to be good with the 2013 Nexus. I don't have one myself per se. I bought one for my fiancee and I'm waiting for the LTE version. But she only charges hers every few days and uses it constantly. More than any other device, including for Netflix.

Ultimately, I find battery life on all my modern devices (Galaxy S3, 2012 Nexus, and 2013 Nexus) to be fantastic and more than enough for my needs.

My Nexus 7 finally arrived today, and I agree... That screen is awesome! It's also really responsive, and it runs rings around any Android device I've used before.

But the thing is the original iPad and iPad 2 were already terrific at battery management. My iPad 2 with a 6900 mAh battery dropped 1% after 24 hours of non use with wifi on and push notifications going the whole time.

Plus it's not even about comparing Nexus 7 2013 to an iPad 4. These comparisons have been going on forever. Whether its an iPad 1, 2, 3, 4, they've had great battery. The Nexus 7 2012, 2013, and Nexus 10 seem to drain much faster.

You can make excuses about the battery being larger, but at the end of the day, Apple just offers a far better standby time for its devices. I don't know what secret they use or what tricks up the sleeve they have, but Android tablets really just don't come close. The best way is to try to Greenify everything and try to kill as many syncing apps as you can and rely on push notifications.

As for people talking about Google+, that thing is a wakelock machine. I know this board doesn't like Facebook, but I studied wakelocks for quite a while and I have quite a few posts on the Nexus 4 development section. Google+ can easily gobble up more battery than Facebook and consume more wakelocks EVEN though I get an average of 1 notification a week versus like 10 a day for Facebook.

the nexus 7.2 i had had similar battery drain to my nexus 4 when sleeping. had wifi turned off during sleep. i don't think it would last month in sleep.

That's nuts! Mine is less than 15% per day with wifi and everything turned on. What's your battery usage like? Also, check you CPU usage states. Should be at the lowest for most of the time.

My wife's ipad mini drains about 1-2% per day as well. Ipad and mini idle drain are still the best.

Yeah, a handful of people are having n7s with dead pixels, backlight bleed and touchscreen issues on a few, too. Most are fine, but asus definitely needs to improve its quality control - this is two nexus 7 launches in a row with QC issues. Still, we're talking a certain small percentage are faulty. Bear that in mind and buy from a brick and mortar store so you can return / exchange if necessary. I bought mine at staples. Opened it in store right after I paid. No immediate issues visible so I took it home, mine's perfect!

.......Whether its an iPad 1, 2, 3, 4, they've had great battery. The Nexus 7 2012, 2013, and Nexus 10 seem to drain much faster..........

Not true. It's all about how the Android device is being used and the capacity of the battery matters heavily. It's simple math. All other variable equal, the larger capacity battery will always drain slower. Otherwise Android can claim the King of all platforms because Motorola makes the MAXX.

I can make my old, radio power hungary, but trusty Samsung Infuse drain 1% in 24 hours too. It's still the best portable music player to my ears. It's all about how you use it. I can do even better with today's chipsets like Nexus 7 FHD. Unfortunately, it's easier for Android users to drain faster due to bad user management and bad apps. On iOS, it's stupid proof.

Considering that most devices use similar amounts of idle power..

Because they don't. Some of Google's innovations, like Google Now I assume, cause devices to consume more power than other devices. And isn't obvious or easy to figure out when and why some of these things are are running. Or to reconfigure them.

I haven't used my new Nexus 7 a lot yet but it does seems better than the original Nexus 7 in this regard. The older N7 had a habit of being dead at annoying times. And also could be a pain to get restarted if it had gone dead.

But it's not always equal. Even device to device. Android is always 1 wakelock away from being screwed. Today you may get 0 FB notifications. Tomorrow you might get 1, and then FB locks up and stays open forever. Then what? It's not Google's fault, but what I'm saying is the experience can vary so much. Today I take a photo, next thing you know Google+ gets in a wakelock mode trying to upload that photo in bad connection.

Furthermore, I realize that you're saying capacity matters. So even if the iPad 4 has a massive battery, a lot of users have been talking about older iPads with smaller batteries. The advantage in iOS battery performance isn't linearly scaling with the battery size--it's far more. There's inherent OS differences resulting in different battery use. It's the same reason why an iOS phone can standby for 2 days easily whereas Android phones of need a much larger battery to achieve those standby stats.

I can make my old, radio power hungary, but trusty Samsung Infuse drain 1% in 24 hours too. It's still the best portable music player to my ears. It's all about how you use it. I can do even better with today's chipsets like Nexus 7 FHD. Unfortunately, it's easier for Android users to drain faster due to bad user management and bad apps. On iOS, it's stupid proof.

So you're saying your Samsung Infuse will last 2400 hours on 1 battery charge? I did a test in this thread (http://forums.anandtech.com/showthread.php?p=34098423), so I highly doubt you can get 2400 hours when I was getting those 530 hours for 65% of battery use on airplane mode.

My question to YOU is what kind of battery drain would you get on a Nexus 7 or 10 with Gmail syncing, Facebook syncing, Twitter syncing, etc? The iPad will drop 1-2% over a day, but certainly I DOUBT a Nexus tablet can achieve that. I have yet to see it on my Nexus 10 at least, so maybe I'm doing it wrong.

Agreed. I mainly became an apple fanboi due to the crappyness of my first android device (droid x) and couldnt believe how stable and smooth iOS ran. My 4S is really starting to show its age and my wife's iPhone 5 is unimpressive other than a slightly bigger screen. I'm finally ready to make the swap to android after my expierence with my nexus 7. Bring on the note 3 and HTC equivalent!

yeah alot of people still base their opinion of Android of yester-year. Every since they introduced Jelly Bean it has been a total different experience.
