[Nexus 7 Q&A, Help & Troubleshooting] bftb0:
Heat accelerates almost all aging & failure mechanisms.

Temperature cycling accelerates some types of failure mechanisms (fracture/rupture type failures)

So leave it on or turn it off every night, which is worse?

So long as you aren't streaming data at full bore 24x7 you will probably be fine leaving it on.

Note I said *probably*. That's because I certainly do not have accelerated life-test data for the N7 sitting in front of me; but even if I did, those statistics would only predict what fraction of units would fail over yeah-many hours/years of service... not which individual units will fail.

So unless someone from Asus comes in here and divulges what their MTBF design goal for the N7 was, or what the first 18 months of the repair stream has indicated about their reliability models, you're not going to get much of an answer to your inquiry.

FWIW, I leave mine on the charger & with the WiFi on when I am not using it, and I have the expectation of using it for a couple more years to come.

recently i played hd movie on my nexus 7

(Movie-300 blue ray version

Frame width-1280

Frame height- 544

frame rate - 23 frames per sec )

and found playback time of 5hrs only

I didn't played entire movie jst calculated in the form that my battery level reduced from 93 to 92 in exact 3 min

Like this i calculate entire playback time ,....

But on internet it says nexus 7 support 9 hrs of hd playback

Plz tell 5 hrs playback is fine for bluray version or I'm having some sought of a battery issue

And if it's a battery issue then what shall i do for its replacement because its been only 1 months

Plz do reply asap.

Regards.
[Nexus 7 Q&A, Help & Troubleshooting] bftb0:
Three minutes (or a 1% change) in battery "percent charge state" is way way too small of an interval to extrapolate from - the sampled data is just way too noisy to be meaningful. A 10% change would be a better measurement. And, those types of measurements should be made in the "middle" of the battery charge state (in the 30% - 70% range, not near the ends).

But - to answer your question - quite a long time ago, [MENTION=4285505]bcvictory[/MENTION] ran many battery drain tests - using a video loop test - with a bunch of different kernels, and most of the results tended to be between 5 and 7 hours or so.

I made some very detailed battery drain measurements playing a video loop about 4 weeks ago on my N7 (MX Player), and without tweaking anything (stock kernel, KitKat 4.4.2) I got about 6.25 hrs for a full discharge (100% - 4%).

So, I guess that means that if you saw an Asus/Google claim of 9 hours, that would probably be a significant exaggeration.

(BTW, keep in mind that for *movies* the GPU isn't doing all that much work, as the scenes are not being rendered from a model - they are just being decompressed from a file (or byte stream). So... that means that you should probably expect even worse battery drain times for playing video games continuously).

nexus 7 overcharging

Sir by mistake i overcharged nexus7 tablet for 1 hour and found out that

That it didn't get discharged for next 1 hour ( in which i surf web , watch youtube videos,and played temple run )

Don't you think it get overcharged for i hour because last time i removed the charger at exact 100 % and it started draining within that i hour

And plz do tell even if tablet gets overcharged

Is it safe ?

Becoz i usually charge my tablet at night.
[Nexus 7 Q&A, Help & Troubleshooting] bftb0:
I wrote a script to "watch" the battery current and voltage in my N7 once per minute (while it was charging from about 4% - 100%) and log the output to a file. (see attached image). So, I think I know exactly why you saw the results you did.

So here is what happens: as the battery voltage rises during charging, the current slowly gets smaller and smaller. Somewhere around 90% the current suddenly starts to slow down much faster in time, and the battery voltage only rises a tiny bit over the 90% - 100% interval.

Here was the surprise though: when the "% charge" got to 100%, the battery continued to charge (slowly) for another 20 minutes. Over that 20 minutes the battery charging current eventually went to zero.

So - it is safe to let your tablet sit on the charger. It is not the charger that determines how much current the battery receives, it is the SMB347 chip in the N7. There is no such thing as "overcharging" so long as the hardware in the tablet is operating correctly. I leave my tablet on the charger all the time when I am not using it, and don't worry about that one bit.

some bugs:

1. when some one call me they didn't get my voice but at the same time I called them back they can hear me properly it is increasing my mobile bill :mad: may be this happen only to me because no one others report the same.

2. Game glitches: most of the games like "hill claim racing", "Gt racing 2", "Thor", acting weird sine I installed this ROM. like car start flying, Teleportation, and many others.

3. Every time I restart the phone it says "android is upgrading" although it's not a big problem but I want to mention that.

4. status bar showing wifi tethering option beside of wifi on/off option, I didn't change any setting of status bar only once try to swipe wifi option to "on" and it start showing that, I just want to know is this new feature.

Point 3: whenever you wipe cache, android will try to optimize...

Point 4: yep its a feature in omnirom just swipe again to get back...
[Samsung Galaxy R i9103] dack1612:
karthik bro I am not blaming you. You are doing great job. I just want to aware guys that it will harm their SGR.

2. I never wiped cache after installing ROM, may any App doing it's own.

3. When I restated the phone it start showing Wifi on/off option again, sorry for mention that but I just want to know is this new features.

and thanks for you answers :victory::good:

someone asked about GPS so GPS working superfine. After long time GPS working like super smooth and fast in any ROM :D
[Samsung Galaxy R i9103] akshayprbhu:
point no. 1 - i too faced this in many calls... but some times it is proper... did a clean re-install as well and still the problem persists..

point no. 2 - there are many games which demand high hardware support like GT racing etc and it FCs i too faced this issue on some games.
[Samsung Galaxy R i9103] Emmes:
yeah, i was asking bout GPS! Thanks for the information!

Is it also working good without internet connection?
[Samsung Galaxy R i9103] rukenau:

But is it possible to Edit Quick Settings Panel Tiles????

Also, Please add charger notification sound
[Samsung Galaxy R i9103] dack1612:
yes It's working fine without wifi or 3g (gprs). I am using sygic offline navigation app.

It lock your position quickly when your are in open may be take 20 to 30 sec, even some time faster than my nokia phone but it's struggle to lock signal when your are under the roof or there are so many trees, but it happens even in GB ROM so it's ok.

for beautiful 4.2.2 ROM for Galaxy R!

You guys awesome.

Sorry for off-topic. I faced the problem with Google Play Store connection on BETA V3. Every time I launch google play store I getting error "No connection."(However, Google Chrome opens google.com, web play store, and other normal web pages) I tried everything that was on xda-developers forums about this problem, nothing helped. But when I clearly downgraded to Stock Indian 4.0.4 play store worked great. After flashing exactly as in [MENTION=4760584]milindthakker[/MENTION] 's flashing guide it got error again. Tested Mobile Data and Wifi Connections. Didn't work. Tried 20140111 latest gapps instead of 20131230 version - no changes. Cleared hosts, changed hosts, deleted hosts, installed mods of Google Play Store, used lucky patcher mods, used older versions of gapps - nothing helped. (after every attempt did factory reset)

I haven't found similar posts with this problem on this thread.

So... did anyone faced such problem on this ROM? Any solutions?

Karthik You haven't answer my question yet

will you going to fix the sound problem when playing music with the earphone(not bluetooth)

1.Playing Music but with noices or lagging,

If you turn on the touchsound in sound setting,and insert your earphone to the phone

Then open your default music player and play some music,you will hear your music (it should be work well otherwise it means your telsa sound driver is broken)

that not what I want to talk about:D

The problem is if you are multitasking when you playing music and touch other stuff together

the music which you are playing will got lagging and have a strange&horrible noise for a few second

after that the music will play normally again.however this problem just looping when you touch other stuff

The solution is turn off the touchsound option in setting>sound>touch sound

Finally you will not hear any horrible noise or few second of lagging

If this problem is not going to fix,my ear should got hurted by this such horrible noise

Solution is in hosts file which can be found in system/etc/ folder
[MENTION=5023629]frost_x64[/MENTION] open that file as text. remove all the lines below line containing

127.0.0.1 localhost

then it will work. Or else if you are too lazy to do so, just delete hosts file. it will work then too. ;)

Actually what happens here is some how a host address is added to the block list in hosts file (i dont exactly remember the address) just like to get rid of ads, adaway adds address' of ads to hosts file. Now there is an address which is accessed by google play(may be to verify something) and since that address is blocked, it couldnt pass further and though internet connection is available, we cant access google play store. :)
[Samsung Galaxy R i9103] frost_x64:
Tried it first!

Opened again - there was only this line

127.0.0.1 localhost

No changes.

Deleted, factory reset, rebooted.

No changes.

Used Hosts Editor App.

Not helping.

I even thought it was google side problem but looks like it happens in all apps with any kind of authorization. Play Store, Hangouts, Yandex.Store... That's really strange...

EDIT: well... something happened. Nothing works when connecting via mobile data, home wifi or notebook wifi AP. But used my friend's phone wifi tethering, and google voice search and Yandex.Store finally worked. However Google Play Store still have no connection retrying all basic solutions to this problem(like hosts file or re-adding google account).

EDIT2: maybe it's some problem with security protocols or something like that because google.com is just http protocol that works good. But can't connect to support.google.com which is https(should be secure protocol) via Google Chrome App. Changed Date and Time - not helped.

EDIT3: well, looks like there is only temporary solution of using 3rd-party store to download apps. hope there will be normal solution soon...
