Rooting and installing a new custom ROM will help with battery life. I noticed on 4.3, the media server bug was present. I had to disable the media server scan. That helped a ton with battery. For 4.4.2 i use purity ROM. In on 2 days one charge with 49% left. You need to charge the battery a few times also as mentioned

Any recommended ROM or Kernel ?

Once you get set up I recommend you look into Xposed Framework, Greenify (app on Play with Xposed enhancements) and Trickster (another Play app for setting kernel behavior).

Good luck,

P.D

P.S. when Paranoid Android 4.0 comes along it will be worth a look. Paranoid Android ROM was conceived with tablets in mind and is incredibly stable IMO. It's 4.4.x release (aka AOSPA 4.0 or AOSPAL for the Linaro enhanced version) should be along any friggin day now.

[Nexus 7 (2013) General] dinjo_jo:
Thanks but does this ROM enhances battery life or worsens ? Also what do you mean by Linaro ? Should i go 4.4.2 or 4.2 as per there post ?
[Nexus 7 (2013) General] pan.droid:
4.4 2 introduced a bunch of security enhancements in light of NSA revelations. I cannot say how much better this ROM is compared to current stock because I haven't used stock for some time. That said, the dev is a very talented one and the rom is popular in a way a battery sucker wouldn't be. The rom contains enhancements over the stock version such as proprietary bionic/dalvic enhancements from Qualcomm that Google couldn't legally include, due to licence issues.

The main factor is in the kernel and the options it gives you. You can disable things like S2W, DT2W, magnet wake thingy, etc. You can also specify the maximum processing power when your Nexus' screen is off/on. Etc, etc.

At a certain point you're just going to have to see for yourself. The fact is that you don't like your current battery performance, so maybe just take the dive and try for yourself?

I will say your questions have been asked and answered a million times before. My earlier reply was the best I could do for you, my friend. For my part, I'm afraid you're going to have to do what everyone before you has done in order to learn more: ask Google before asking anybody else.

For example, regarding your Linaro question:

Try searching 'Android Linaro'

Question about bionic or dalvic? Try the same thing, maybe you'll have to adjust your search to include 'Qualcomm' (the brand of processor in our device).

If it's frustrating not having all the answers at your fingertips then celebrate! It's that frustration that will motivate you to find your answers.

For now, though, maybe start reading up on the links I gave you. There are ways to return to stock if you feel you need to (you'll also need to do your own reading on that).

Arguably, all the business of unlocking, rooting, flashing, etc. is probably easier on Nexus devices than it is or has been on 99% of contemporary or former Android devices. So, you're in pretty good shape off the bat=)

---------- Post added at 06:05 PM ---------- Previous post was at 06:02 PM ----------

P.S. make sure NFC, BLUETOOTH, LOCATION (aka GPS) & WIFI are disabled in Settings when you're not using them.
[Nexus 7 (2013) General] wizzlewizzle:
The kernel is the most important when it comes to battery life because it Controls cpu and kernel and io operations.

I recommend using elementalx kernel because it has deepsleep state which will allow your device to save the most battery when you're not using it. I'm sure there are others but that's what I use.

The largest battery drain during use is the screen, so keep your screen at a minimum whenever you are using it if you're concerned about battery.

Another thing you can do to improve battery is undervolt. However you will only experience minimal benefit because you can only undervolt so much before your device is unstable. I don't recommend undervolting for newbies.

Another thing that can improve battery life is multicore power saving, a setting that is enabled with a custom kernel such as elementalx.

Another thing that I've heard that CAN help battery life is using Art, instead of dalvik cache. This is highly debatable, but some have reported improved battery life. I use art but mostly for the improved performance and load times, rather than the battery life.

Of course you should turn off anything you don't use, blue tooth, nfc, GPS, etc.. To help better manage this automatically you can use an app called profile scheduler.

-Wizzle
[Nexus 7 (2013) General] pan.droid:
Wizzle, I've heard ART isn't stable with apps that haven't been retrofitted to ruin with it. Is that your experience?

---------- Post added at 11:59 PM ---------- Previous post was at 11:52 PM ----------

Incidentally, there's a new 'Glitch' kernel released today. Just checked and it also goes into deep sleep. You may want to check it out... it, too, uses the Aroma installer and seems to offer a few more degrees of customization. Just make sure you snag the right one as there are a few different builds depending on your rom source.

Which rom do you use?
[Nexus 7 (2013) General] dinjo_jo:
I have installed the .AOSP Kangs][DJL4.4] ROM last night due to some reason some apps are closing on it. Will try out the new kernel.
[Nexus 7 (2013) General] pan.droid:
Yeah, I have the same ROM and have used both ElementalX & now the latest Glitch kernel. Odd you're having force close issues, tho. Pretty sure that isn't something many others are experiencing. Do you run other mods? Is SuperSU working okay?
[Nexus 7 (2013) General] wizzlewizzle:
I'm on cm11. I've tried glitch, but not the latest. Most of the customizations glitch offers is basically more overclocking and undercoating, I prefer stock values for stability, I've over clocked before just to see how fast I could actually get my Nexus to work, but of course you don't get the best battery life..

I've had 100% success with art. It has not been unstable one bit. It's definitely faster and I don't have to overclock which saves battery.

One word of caution! If you sideload apps, sometimes they will no longer install once you enable art. Oddly enough if they were installed before art was enabled, it works fine! (hehe at least that's my experience)

Another word of caution, once I've enabled art, I was not able to go back to dalvik unless I deleted all my data and reinstalled apps from scratch.. I recommend doing a nandroid backup before you enable art, just so you have data that is dalvik..

[Nexus 7 (2013) General] AssailantLF@gmail.com:
My battery life is like what most people are saying, over 10 hours of use doing various things... other than 3D games with hour+ play sessions. Basically if I'm playing something like GTAIII or Final Fantasy III, battery life will go down considerably faster, but not devastatingly so, probably like 50% faster, and only while playing.

Here are some things that will dramatically help your battery life, assuming it isn't defective or something:

Having the brightness on auto or generally very low will help a lot. If you look at battery usage in Settings, you'll see that the screen usually eats more than half of your battery at all times.

Keeping GPS/Bluetooth/Wifi off when they aren't needed.

Closing background apps.

Turning the screen time-out down, which can be found at Settings>Display>Sleep. The Nexus 7 '13 has a pretty average battery, but one of its best qualities is how it barely loses any power when it's on standby.

Don't use live wallpapers or turn their quality settings down.

I'm using CleanROM which is just a stable, prerooted, more optimized stock AOSP rom and keeps up to date very quickly. My battery/performance is loads better than it was on stock. I couldn't recommend the rom more, especially after installing Xposed Framework and the GravityBox module, which allows you to to have many CM/PA features without much effort.
[Nexus 7 (2013) General] jonnythan:
I get 10+ hours with WiFi and location on all the time. I do keep the brightness down a bit. If you're getting half that, something is wrong.

Not gonna lie. I know there are a few threads claiming that they have the "best leather case", and perhaps they are very good, but the one I ordered is also very top notch.

I ordered the case through here.

The package came in about a week, which is pretty decent. The case has a dual tone leather, brown and black, and the stitching pattern looks like a book. The back has a camera hole and speaker holes. It also has this little attachment at the back that I have no idea what is for. The leather is PU leather. The leather is also pretty darn thick too.

The inside has card holders, a strap for your hand when you're holding the case with the front flap flipped to the back, and two holder things I don't know what's for, but I bet for creative people you'll find a way to use it.

The pouch for the tablet is very secure, more secure than the other leather case I have. Normally cases have this plastic thing that snaps on to your Nexus 7, This case, however, has a stitched leather pouch around the tablet, and it has a velcro thing to secure the tablet in place so it can't slide out. The case has a hole in the front for the little LED light thing. The case also has a smart cover.

I've had this for about 2 weeks and I'm very happy with it. I highly recommend this to anyone looking for a sophisticated leather case!
[Nexus 7 (2013) Accessories] naturecannon:
Ya the case does look sexie :D
[Nexus 7 (2013) Accessories] Jimmy2u:
Its look quite ok ok but not much impressive or elegant one...not a shopping material....

PU "leather" is in no way, shape or form actual leather. It is a disingenuous term used to confuse the buyer into thinking "PU" is a type of leather, which it is not. PU stands for polyurethane, which is plastic. Not leather. :good:

Ok Im not really sure what i am doing wrong I read alot of websites but just cant really find the problem im encountering. I downloaded 10.2 via computer and transferred to SD card, I rebooted into recovery and I wiped data/factory reset. Then I install update from sd card option and select the 10.2 cyanogen option. Everything starts then it goes something like "failed to verify whole signature", then it just ends up restarting as a new device. I have clockwork, goo manager (which I didnt do anything with). under clockwork I have TWRP set up.

To be honest i have no clue really what Odin is, and thought (as most walkthrus didn't comment) that odin was an alternative to flashing but not required?

You have lost your recovery for some reason. Just reflash the latest TWRP from here

Shut off your device. http://techerrata.com/file/twrp2/m7wls/openrecovery-twrp-2.6.1.0-m7wls.img

Copy the file to your ADB folder on you PC. Plug the USB in.

Press and hold volume down and then press power. Keep holding volume down until a menu shows on your screen.

Use the volume rocker to select fastboot and press power to select fastboot.

Plug the device into your computer.

If you have the right drivers installed your phone screen will now say: FASTBOOT USB

Using a command prompt, type:

fastboot flash recovery recovery.img

fastboot reboot-bootloader

Your device will reboot. Use the volume rocker to select recovery and press power. You will now boot TWRP.
[Sprint HTC One (M7)] Xperi.a:

Here is the link to mini ADB (same as ADB) https://docs.google.com/file/d/0B1S0LCuXCnnmSWh6NGJmSE1BUWc/edit?usp=sharing

Uninstall all the HTC stuff from you PC and install only this driver http://xdaforums.com/attachment.php?attachmentid=2155881&d=1375297569

Go to the path where you installed the Mini ADB and from there open command prompt.

Copy the desired recovery to this folder

Put your phone in FASTBOOT mode Finally insert this command in command prompt:

fastboot flash recovery ---.img

I've restored the backup and everything was working fine but i noticed that I lost my sim unlock and my phone is rebooting in every 1-2 mins.

Please accept my sincere apologies for PM'ing you. I'll make sure I dont do that again and I've thanked all your posts. You are really a superstar sir. Hats off to your advice and posts.

I think the reason you are rebooting is because you flashed the wrong version of CWM.

Should I again flash the badboyz rom?

I remember while I recovered twrp recovery I did some kind of format/wipe. I guess because of that I lost my simunlock and possibly deleted something which is making it to do so.

Should I download badboyz rom again and flash it?
[Sprint HTC One (M7)] BMP7777:
NO, follow BigDaddys advice and RUU back to stock. Then work your way back to other ROM choices, most likely after flashing a new and appropriate recovery.
[Sprint HTC One (M7)] elvisypi:
Yes first try reflashing the ROM after full wipe. You shouldn't loose your SIM unlock no matter what you do so smth is messed maybe with your partitions

If it doesn't work you should run the ruu. It'll brink you to stock and would have to unlock bootloader, root, custom recovery, etc.
[Sprint HTC One (M7)] Xperi.a:
I guess I've loosed it as I bought the phone from ebay and it came unlocked for sure but when I restored the backup I saw no signal bars on my phone,

Anyways, I'm again downloading a fresh copy of the rom and will re-install it. I dont want to do RUU and and they again everything from scratch as that would be toooo time consuming.

Hope reflashing works. I'll keep this thread updated.

Tho, While restoring I found a error that .android_secure.img is not found.

I guess that is something I messed?
[Sprint HTC One (M7)] Xperi.a:
UPDATE:

I did a full wipe and re-installed the Bad Boyz Rom.

I suggest InserCoin 6.0-5. Your unlock won't work on CM or AKSP, GP ROMs like the Nocturnal, it works only on sense based ROMs. The Badboyz ROM doesn't have any bugs so it's either your download wasn't correct or you didn't full wipe

re: odin flash - JIG

What I would do is go to ebay or online stores and buy a USB JIG it works perfect on Samsung Galaxy S4

and other android phones. The price is right too, anywhere from $1.00 to $5.00 including shipping.

Here is a link worth looking at:

https://www.google.com/search?q=andr...icial&tbm=shop

JIGS are made for issues just like the ones you and @lasallegreen are experiencing.

All you need to do with the jig is first remove the battery from your phone for

20 seconds and replace it, then plug the USB jig into the usb port of the phone.

Wait a couple seconds or so and you will see the download mode screen.

Unplug the usb jig and load/open odin and after putting the stock rom in the

pda slot in odin connect usb cable from phone to computer.

Make sure the [COM:xx] lights up in Odin and click START.

Once odin successfully flashes the official stock rom the

phone will again be in perfect condition ready to use.

Your phone is NOT hard bricked, but most likely it is soft bricked meaning that it can be fixed to

come back to life after Odin flashing the official Samsung S4 stock firmware/rom which you can

find and download from http://SamMobile.com by searching by the model number of your phone.

Good luck!
