4.4.3 (and 4.4.4) should have better battery life since they fix a couple of wake lock issue:

4.4.4 is just a fix on a OpenSSL bug

i got my nexus 4 last year Jan (although n4 was launched oct/nov 2012). so, it'll be more than 18 months by the time L release next month. minus all the minor iteration, we get free upgrade from the initial 4.2 (another Jellybean) to

- 4.3 (sweeter jellybean) with Bluetooth Smart Ready, OpenGL ES 3.0, merge and re-organize 2d graphics, etc
- 4.4 (kitkat) Project Svelte, experimental ART, new launcher, etc

About the 18 months cycle support, that is just what they officially stated. "little bird" told me the real reason Nexus Galaxy not getting Kitkat is because of it OMAP SOC developed by Texas Instruments; a company that's no longer actively developing smartphone chips.

i m fully confident that L will be released for nexus 4. if goog dont release that, i m jumping ship to iOS.

my ipad 2 (2011) still got update... more than 3 years...

if my nexus 4 less than 2 years old not getting L release, it's my way to show the middle finger to Google.

ps: my ipad2 will still get the next version iOS 8 when they release in a few months later...

source? https://android.googlesource.com/platform/build/+/l-preview ?

anyway, to try it yourself, just install Android SDK: http://developer.android.com/sdk/index.html

Start the SDK Manager.exe, download the L platform.



Start the AVD Manager.exe.



"Create" a new Nexus 5/7 device, use L as the OS.



Start your engine!

hehe paishe lar... dont talk about my gaming life ler...

u can use the same sdk to run Android TV, Android Wear...

thinking Moto 360?

well, you can start "playing" with it with the Android Wear Round emulator!

i read somewhere before the barometer only meant to help to lock GPS faster.

let me start by saying nexus 4 battery is not the best. but if you practice leaving your phone charging over night, every night, you should have no problem.

i typically only charge the phone once every 2 nights because i barely used 50% battery everyday. my usage and preferences has a lot to do with it:

1. have wifi at home and office - phone save more juice when on wifi
2. have no facebook, wasapp, twitter installed - i use web and google plus
3. undervolt my phone to around -175.

IMO, most battery related issue are due to wakelock in the phone. the 2100mAh is not big by today's standard, but if you leave your phone in air plane mode, off screen, it could last 1 months!

Well, the idea is, if you can let your phone truly "sleep", your phone can last very long.

Unfortunately, most app went out of the way to try to work harder for you. This is especially true for social media app that need to keep you updated to the seconds. They end up waking your phone too regularly. Say 1 app, wake up every 30 minutes, check if there is any new messages for 1 sec, if nothing, go back to sleep. 1 sec in 30 minutes is not that bad right? Well, it turn out that, that 1 sec of waking up, may "echo" other to start busy-body and start checking things. other app (such as radio) will continue to check if signal is okay for another 5 minutes while the CPU is awake.

now, what if, there are 5 of such app, that wake your phone for 1 sec every 30 minutes? you get the idea.

so, enter the Project Volta!

Android L will have better battery life due to Project Volta. Google identify those issues, and is now pushing for developer to use "JobScheduler" API to push for more battery efficiency.

What it will do? Every app now should use JobScheduler to do background stuff. Instead of waking up based on each app, the OS will now consolidate all request and do it in 1 shot. Wake up 1 sec, do everything as fast as possible, and go back to sleep.

You are right. That will only be effective if every app participate. Good guy google will "eat their own dog food" (their term) and start using this in all their app. So, a Nexus 4, running only Google stuff in L release, you should see something like 30% better battery life (some already tested it in the preview). But as soon as you start putting your other favorite app, if they not using JobScheduler, the efficiency may decrease.

See for yourself



And 1 last thing, will you see a better SoT with L release? May be not. SoT may not be best to measure a phone battery life... AMOLED will always win. *wink*

personally, i chose IPS over AMOLED, anytime. i like bright screen.

pretty good summary:

http://www.phonegurureviews.com/ips-vs-amoled/

not useless. at least the OS will be more power efficient. it only take 1 bad app to drain your battery. nothing is changed. good thing that they now include a more efficient Battery Historian that may allow you to identify the culprit and take the necessary action.

i'll never run something like this in my nexus 4

Who is getting L release? Based on L preview source code Google published, the following device has new "L preview" build, which mean, they are working on getting L release to work on these devices.

Nexus 7 and variant:

device/asus/deb

device/asus/flo

device/asus/grouper

device/asus/tilapia

Nexus 5:

device/lge/hammerhead

Nexus 4:

device/lge/mako

Nexus 10:

device/samsung/manta

Android SDK emulator:

device/generic/goldfish

Not in the list:

Galaxy Nexus - Maguro / Tuna

Nexus S - Soju / Crespo

So, as you can see, L is coming to Nexus 4

Something interesting about the Google Search update this morning:

Successfully cast my phone into my TV via the "Cast Screen" and Chromecast attached to my TV.

Feel awesome to view photo/video recording in the phone in a big TV at a simple touch.

does not look like nexus is going to an end after Nexus 6:

"People have been commenting about Nexus because there is something else and they think that means the end of Nexus. That is the totally wrong conclusion to make," Burke said.

http://readwrite.com/2014/06/26/google-nexus-android-silver

personally, i m quite excited if HTC will build the next Nexus.... i was so close in getting HTC one previously... really like the hardware... micro-drill speaker holes, metal uniform frame, etc

however, dont think any phone is able to make me upgrade my nexus 4 any time soon...

everyday, i browse thru Google Play, hope to find an app that will make push my n4 to the limit... some games may be, that may perform poorly on my phone... but none...

Another smooth gameplay record

Act 1 Boss fight



ps: i am the left hand side shadow guy...

Act 5 Boss! I am getting good at this!

hahahahah! thanks for watching anyway! will take a break before fighting the final act

Final Act 6 Final Boss! Too bad the game ended with no option to roam the world and fight anymore... just end...



ps: it's free after all been fun

(recompiled kernel with linaro, tweak the RAMDisk's OnDemand governor, lower GPU idle voltage, etc)
