Google's Android L Project Volta boosts battery life by more than 30% on one and the same Nexus 5

Google's Android L Project Volta boosts battery life by more than 30% on one and the same Nexus 5
One and the same worn out Google Nexus 5 handset, loaded with the new Android L Preview, and Android 4.4 KitKat, showed a significant gain in battery life in standardized, controlled testing. The Nexus 5 with Android KitKat has been charged up to the max, and a standard web browsing test run with the screen set at 200 nits of brightness. The Nexus 5 lasted 6 hours and 45 minutes before it died completely. Afterwards, the Android L Developer Preview version was loaded on the handset, and the same test run again at 200 nits. Surprise, surprise, the same Nexus 5 lasted almost 8 hours in the same conditions. This comes to show that Google's new Project Volta that comes with Android L, and is aimed to optimize battery consumption, works as advertised, and the folks from Mountain View are even conservative in saying that it boosts battery life with 15-20%, compared to previous versions of Android. 

Project Volta consists of many moving parts, like the Battery Historian, or the JobScheduler API, many of which are on the developer side of things. End users also get visible perks, though, like the Battery Saver mode that can be enabled from the settings, or kicks in automatically when the battery reaches 15% charge. The results of this impromptu test with the Nexus 5 are nothing short of breathtaking, though, and, given that H1 flagships already last about 30% longer than the 2013 crop, another such boost will finally bring the situation with smartphone battery life on the bearable side.

Yes it really is. Imagine on a phone with GREAT battery life like say a Note 3... That's very impressive indeed...

Is this necessary, hater?
Also you need learning punctuation and sentencing. :)

Agreed
Also you can flash a custom kernel to get even better battery life
Can't wait to have Android L + ElementalX on my Nexus 5

Battery life is pretty good on L,
I almost can't believe it improved this much.

I definitely have noticed an improvement in battery life, but I do wish they'd optimize the developer preview a bit more performance-wise. My Nexus has been lagging and stuttering every now and then (but, again, it is just a preview.)

Turn transition animation down to .5 or off an force GPU for 2d environments, is it still stuttery?
I have no bog downs or stutters my N5s.

Unfortunately that didn't help. It's only really lagging when I swipe over to Google Now from the home screen, and in the new multitasking menu. Also, I was previously getting Quadrant scores of 14,000+ on 4.4.4 (stock + ART) whereas now I'm getting around 7,000, and the main culprit appears to be framerate.

Something is bogging that thing down big time. Hope you can find culprit.

What other choice do you have?

I've already owned a N5 but the poor battery life made me sell it...

Frugal OS, frugal apps. Fingers crossed, the average flagship smartphone gets 10+ hours OST by 2015.

It's impressive indeed !!

But I believe brands like Samsung, LG are already doing those type of similar optimizations lately .. So this would probably not show that much (30%) improvement on phones like S5 or G3 ..

This is great news for people who struggle to get their phones to last throughout the day without connecting to a charger. See, now this is the stuff I wanted to read about during their conference, not their cardboard VR headset.

Yeah that too. But if it turns pricier, i would get the 5. I'm really on tight budget this year. :(

I doubt it would be much more expensive than the Nexus 5, if at all. Either way, wait until the Nexus 6 comes out, even if it is outside your price range, the price for the Nexus 5 will drop on it's release.
