Our Nexus 5 battery life test is ready, Grumpy Cat is not impressed
Nexus 5 battery life test
We measure battery life by running a custom web-script, designed to replicate the power consumption of typical real-life usage. All devices that go through the test have their displays set at 200-nit brightness.
13 November Our Google Nexus 6 battery life test is complete, phablet lags behind the Note 4
31 October Step aside, Sony Xperia Z3, the Motorola DROID Turbo is the new king of flagship battery life
27 October Apple iPad Air 2 battery life test: shorter battery life despite Apple’s claims
10 October Surprise, surprise! The Note 4 defies expectations by acing our battery life test, becomes the longest-lasting QHD phone
2 October Our Meizu MX4 battery life test is complete: ties with the Samsung Galaxy S5 and HTC One M8

That's pretty bad if kitkat is supposed to be less power hungry. Would that mean that the Nexus 5 might be dead last after the competition gets the update?

Being less battery hungry is not Kitkat's primary aim. Being faster and requiring less ram for system processes is.
9. cripton805 (Posts: 995; Member since: 18 Mar 2012)
Its faster because if requires less ram and processes. Thus should improve power consumption... Which goes hand in hand. Get it? Guess not.
10. ilia1986 (unregistered)
No it doesn't. Just because less ram is being used and the overall performance is better, doesn't mean there is significantly less stress on the battery.
13. cripton805 (Posts: 995; Member since: 18 Mar 2012)
Yes it does. It requires heavier usage of its processor which in return cuts its battery life even while the phone is idle. Also, some of those phones have skins on top of the stock OS. It does affect the battery life.

I dont think so,as all the hardware is going to work as normal,but the software is way lighter than other versions,so you get a much more fluid and smooth performance in the OS but with the same battery life
you can underclock the processor if you root your kitkat device,and that would make battery consumption way better
11. tech2 (Posts: 2436; Member since: 26 Oct 2012)
I think it only uses less RAM when there is a constraint.
It won't make sense if the phone has 2GB ram and Android deploys sequential launch to conserve RAM. That would slow down the phone a bit.
15. cripton805 (Posts: 995; Member since: 18 Mar 2012)
Yes, PA also noted that Google modified Google services and the OS as a whole which puts strain on the devices on its own. Try running 100mb or more of apps in the background and you will see a difference in battery life. Just like apps, the os and services put a strain on the device and by making them more efficient, it also helps the battery life.

Uhhhh no, ram and cpu still take a major back seat to the DISPLAY which eats about 80%+ of all batteries in any smartphone. So unless Google magically found a software way to limit screen battery consumption, battery life will remain the same. Making the OS more ram and cpu efficient would have a marginal (read

Screen and wireless technology use the most power in my experience.
56. cripton805 (Posts: 995; Member since: 18 Mar 2012)
Do you pay attention to anything Im posting? Who said that the screen wasnt the major reason that it drains more quickly? I know that the screen is going to be the #1battery killer or maybe #2. As of right now, my own battery on my GS3 has been drained 26% between the OS, Google services, and system idle. The screen was only 33% because I have my brightness set all the way down and on my GS3 its still bright enough to see.
Do you people even know that you can look this up on your phones??? You can see how much battery the OS uses up on each specific category.
57. cripton805 (Posts: 995; Member since: 18 Mar 2012)
Oh and they have been improving battery life with software updates for years... I know because Ive been an Android user since Eclair and I tend to follow up on the news about the updates.
43. jove39 (Posts: 1328; Member since: 18 Oct 2011)
Well...kitkat is supposed to be power efficient...you'll find it in coming releases.
8. woodshop20 (Posts: 459; Member since: 14 Sep 2013)
Well, you can't complain too much. The Nexus 5 costs almost half that of an HTC One,.
23. bucky (Posts: 1574; Member since: 30 Sep 2009)
It's quite expensive when you consider it off contract vs price of another phone on contract. Also, it can get quite pricey in many parts of the world.
Don't get me wrong, great phone but the price can't keep being the excuse for the nexus short comings every year. Battery and camera are always a slight concern with nexus devices.
26. fanboy1974 (Posts: 1289; Member since: 12 Nov 2011)
I would pay $350 all day long if it meant not being locked into a contract. Sure I can get a lg g2 for $100 on contract but there are some pretty good prepaid plans such as t-mobiles $30 a month plan. Just by ending one of my verizon lines I will end up dropping $90 total ($40 for the phone and $50 for data on my family plan). That's a savings of $60 per month if I go t-mobile. In one year that's $720 dollars saved. No Verizon contract phone can beat that.
28. bucky (Posts: 1574; Member since: 30 Sep 2009)
In Canada, the plans are the same whether I sign a contract or not. Also, the contract cancellations after a year or so are almost always lower than the resale of the phone.
84. networkdood (Posts: 6326; Member since: 31 Mar 2010)
That is what I am doing - running my Nexus 5 no contract for 30.00 a month with T- M0...great great deal
42. QWIKSTRIKE (Posts: 913; Member since: 09 Mar 2010)
When you compare it to a contract phone it can definitely win either way. On contract it's 49.00 at Sprint.....this is the price of lower level phones with half the specs of this. Either way you buy it it s a steal for what it is contract or not!
44. bucky (Posts: 1574; Member since: 30 Sep 2009)
That's awesome if that's the price there. I see it listed for full contract prices :/
80. jimv1983 (Posts: 22; Member since: 10 Oct 2013)
The 32GB HTC One is $650 off contract. The 32GB Nexus 5 is $400 off contract. The Nexus 5 is just over 60% the cost of the One not less than half.
17. Evil_SaNz (Posts: 258; Member since: 20 Oct 2011)
Pretty bad 10 min less vs galaxy s4 while having a cpu clocked crazy high? Not understanding.
41. QWIKSTRIKE (Posts: 913; Member since: 09 Mar 2010)
Not too bad when you consider it has a 2300mah battery, and the G2 has a 3000. The battery is last years technology size wise....wake up!
74. 4.1.2 (Posts: 11; Member since: 30 Oct 2013)
So not getting this phone now.... The commercial looked cool but this.... No
2. TrueGee85 (Posts: 7; Member since: 25 Sep 2013)
Disable Google Now and you will see an incremental increase in the battery life. It worked on my Nexus 4.
18. dexter_jdr (Posts: 1162; Member since: 28 Jun 2012)
i thought google now is just an app for downloading apps?
how is battery affected by it
25. orca99 (Posts: 87; Member since: 05 Oct 2013)
No, google now is not for downloading apps. Have you actually used android ever?
38. dexter_jdr (Posts: 1162; Member since: 28 Jun 2012)
just borrowing tab2 10.1
i only know its a menu on every android to update/search apps
51. Klamba92 (Posts: 206; Member since: 25 Jun 2012)
No you are getting confused with the Google play store which is the place where you can get apps,books,magazines, tv/movies and music depending where you live! Google now is a service that tries to predict and give you relevant information to you when you need it. For me it works amazingly!
66. rd_nest (Posts: 822; Member since: 06 Jun 2010)
If you are outside US/UK and a few 1st world countries, google Now is useless anyways. So you better disable that.
it caused severe wakelocks.
77. dexter_jdr (Posts: 1162; Member since: 28 Jun 2012)
no. im better than iusers.. i dont have a smartphone :D
-well at least i can do better grammar than you
3. ilia1986 (unregistered)
Almost 5 hours of screen time is very very very good, regardless what your phone is.
I got a GS3, 2100 mAh battery, CortexA9 - not nearly as new and efficient as the Snapdragon 800. I got 4 - 4.5 hours of on screen time, with multuiple widgets refreshing in the background as well as numerous tweaks running as well, but that's due to SlimBean 4.3.1 build 2 I'm running atm.
5. mittalmailbox (Posts: 43; Member since: 14 Feb 2012)
In addition lg g2 have additional display RAM to reduce power consumption.
6. Kal-el (Posts: 91; Member since: 14 Dec 2012)
My xperia z1 does a day and a half...i leave data on for about 60%-70% off the day ...plus bbm now....granted i'm not a heavy user but i do play games every so often even then i would have to charge it late at night after the day is done....so this much be some intense usage test
7. ilia1986 (unregistered)
Your phone DOES NOT last you a day and a half with the screen BEING ON for 36 hours. Unless you have a nuclear reactor instead of a lithium-ion battery lol.
12. eggimage (Posts: 68; Member since: 19 Jan 2012)
Kal-el, you obviously have no idea what you're talking about here.. there's no way your z1 can be like 7 times better in battery life than other phones
81. Kal-el (Posts: 91; Member since: 14 Dec 2012)
the article claim "We measure battery life by running a custom script, replicating the power consumption of typical real-life usage."
"real-life" To me means the screen goes off when ur not using it
If this test means the screen is on constantly then Yes my phone would not last a whole day it would last a couple of hours Therefore making this "real-life" quote by PA highly redundant and should have just called it a endurance test....so forgive me for phone arena's mistake
...so i repeat at work i can't really use my phone constantly other than checking mail thus nearly 30-40% of my day it's not being used fully and when i do "game " on it...it lasts only a day but till the end of the night thus meaning only a relative 12-14 hrs... without gaming it last till the next day...granted i have to charge in the morning since it's like 10-15% and considering i OWN the phone unlike some commentators here....i would know -____-
87. Pancholo (Posts: 377; Member since: 27 Feb 2012)
Fair enough. Going by your logic, my Note 2 lasts me a whole week. Suck it! Of course, you can't touch it.
Real-life experience, yo.
14. techguyone (Posts: 114; Member since: 18 May 2013)
They should have stuck in the 3k battery instead, this is a big fail for what otherwise would have been pretty good.
21. ilia1986 (unregistered)
Yeah but they chose to go with wireless charging instead of a bigger battery..
33. NexusPhan (Posts: 538; Member since: 11 Jul 2013)
In what world is 5 hours of screen on time (the same and the GS4 with it's much larger battery and the same as hte iphone 5S with it's much smaller screen) bad? Please explain how this is anything other than great battery life.
70. jimv1983 (Posts: 22; Member since: 10 Oct 2013)
Saying 5 hours screen on time is good doesn't mean much unless you consider the total time off the charger as well. If a phone gets 5 hours of screen on time but also only 5 hours off charger that isn't good at all. If it gets 5 hours of screen on time over like 20 hours off the charger I'd say that is pretty good. Personally, I'd be happy with like 4 hours screen on time with like 15 hours off charger. I'll be getting my Nexus 5 tomorrow or Monday. If it gets the battery life I mentioned I'll be happy.
63. jroc74 (Posts: 5192; Member since: 30 Dec 2010)
Please keep in mind whatever this test, script was isnt typical use for everyone.
I posted battery tests for the GS4 that gsmarena did that showed great battery life doing specific things. But according to this tests here, battery life isnt that great.
16. scriptwriter (Posts: 396; Member since: 13 Nov 2012)
Define real world usage? You can't, can you. This is because everyone is different and will therefore have different experiences with battery life. This is a lab test not a real world test
30. Martin_Cooper (Posts: 634; Member since: 30 Jul 2013)
Very true, but no matter what you do if you use nexus 5 same way as an LG G2 it means LG G2 will always have a much better battery, Simple as that.
76. LoveHater (Posts: 161; Member since: 09 Oct 2013)
But Lg g2 wouldn't have 4.4 soon and probably not 5.0
34. NexusPhan (Posts: 538; Member since: 11 Jul 2013)
This is real world usage of what happens with the screen on. Expect up to 5 hours of screen on time. So, for most people, easily a full days worth of battery.
19. LiquidGalaxy (Posts: 252; Member since: 03 Jul 2013)
I don't see how the 5s battery is only 3 mins better than the S4 which makes me question this test. After going to a 5s from an S4, I get 15-20 hours more on my 5s...Right now my standby usage time is 1 day 14 hours, the S4 could get no where near that......
24. bucky (Posts: 1574; Member since: 30 Sep 2009)
I have to agree with you there. With the same usage on the s4 I had, my 5s lasts significantly longer.
I guess it really depends on the variables in the test.
78. LiquidGalaxy (Posts: 252; Member since: 03 Jul 2013)
Not really sure i understand this response, i'm assuming its incredulity of some sort. Believe what you want, the usage times speak for themselves - my 5s died at 1 day 18 hours standby time yesterday. The most i ever had with my S4 in the time i had it was 1 day 1 hour, so yes, 15-20 hours more...
31. Martin_Cooper (Posts: 634; Member since: 30 Jul 2013)
I have an iphone 5 which has tiny bit of less battery than a 5S. And lets suppose 5S has more efficient cpu/gpu how the hell you get 15-20 hours more battery life when me and other friends with iphone 5 get same battery life with an S4. Some times worse some times better. But tiny bit. Is your 5S on the lowest brightness and everything off even making calls? Thats the only way you will get 20 more hours than asn S4.
35. NexusPhan (Posts: 538; Member since: 11 Jul 2013)
This test is screen on time only. You'll get a lot, lot longer standby time with the GS4 but similar screen on time. Seems pretty simple. Not sure why everyone is having such a difficult time understanding this screen on time test.
45. jroc74 (Posts: 5192; Member since: 30 Dec 2010)
Yea I added the iPhones to the list, and thats what made me post what I posted below.
We need tests from Anandtech, GSMArena for a better overall picture of battery life.
20. Klamba92 (Posts: 206; Member since: 25 Jun 2012)
This is interesting as when I was testing the s4 it had great battery life with 4g granted I was going between normal and power saving mode with about 22 hours of usage. My dad is still charging his iPhone 5s twice a day just like the iPhone 5. Hopefully this means nexus 5 won't be as bad as people are saying? Anyone who has one please tell us how the battery life is after all everyone has different usage?
22. AeroPrime (Posts: 173; Member since: 21 Feb 2011)
Oh come on guys this what nexus is for. You and I know battery life for the nexus is not really that great. This is just a great android user experience.
