    I usually have decent battery life (12+ hours with 4hours ish sceen on time) but every now and then (maybe fortnightly) I will notice the battery draining alot quicker, I look at the stats and Google Play Services seems to be the culprit. Is it usual for this to cause battery drain on a seemingly random basis?

    Yeah. I think that's common. I manage this stuff now so that it runs on my terms. Battery life on a full charge is about two days, provided I'm not doing extra stuff on the phone, especially playing games, for an extended amount of time.

    Check out the Snapdragon BatteryGuru app. I like to set it up so that other apps only connect when I run them, unless I want live notifications from them, then I set them to connect as they want, like my work e-mail, which is set to Automatic (Push).

    Play services can be a big battery drain, as its probably syncing apps and their data, location, or other things in the background.

    There was a recent update that should have taken care of the location problems, but the others is likely based on what you have it syncing.

    Do you have Dropbox on your phone? If yes do you have auto synch phots enabled? If yes, try disabling auto synch on the Dropbox app.

    Can you check the play services version in settings/apps/all? Is it 4.1.x? 4.1 fixed the location issue that Rxpert83 referred to - I noticed a significant improvement after that update a week or so ago.

    Looking in App Info, I find that the Google Search page has permissions to:

    "directly call phone numbers - this may cost you money"
    and
    "edit your text messages, read your text messages, and send SMS messages - this may cost you money".

    I can't believe that an app is able to send text messages and especially make phone calls without me knowing! Surely this can't be right.

    Is there something I should do about this or, hopefully, have I misunderstood the meaning of these statements?

    It doesn't say without you knowing. It just says it may cost you money. If I use Google search bar or Voice search to turn up a contact, I can then call or text to that contact. Or, I can ask OK Google to call my favorite restaurant. If it did not have those permissions, which it showed me when I downloaded it, it couldn't do those actions.

    By and large, the functionality we want in our mobile programs require deep permissions. Apple, Windows Phone, hell, even Palm and Win Mobile had some of those capabilities all along. At least, here, you are being told, before downloading, that it will be able to do those things. ;)

    I really enjoy having choices of how I setup my phone to sync my various apps and accounts, it's a huge advantage of the Android OS. By taking some time to think and plan my setup according to my needs I'm experiencing excellent battery life even though I'm a very heavy user.

    Already very happy with it's ability to breeze through a twelve hour workday, I still have over 35% to use in the evening.

    Then I found the Qualcomm BatteryGuru app. After it's initial learning period where it monitors one's usage it then begins extending the battery life significantly. In addition it also features user adjustable preferences on a per app basis for robust granular control. Now after doing some fine tuning I've been enjoying nearly double the battery life. All for free, an exemplary app.

    The terrific experience I'm enjoying with my Nexus 5 has exceeded my expectations beyond what I thought possible.

    Between the batteryguru for snapdragon and enabling ART, I've noticed a difference in battery life.

    ART is still unfinished, but it's already doing well. The tradeoff for using it is about 10 - 20% more space used up by your apps (so they can launch faster, meaning less processing power, meaning less battery used).

    Android police did a study on battery life and the conclusions were basically that ART had little to no effect. It was actually worse in certain scenarios.

    Meet ART, Part 3: Battery Life Benchmarks - Not Good, But Not Too Bad

    Hard to take too much from it though without delving deeper into how they did it. Methods make or break a study.

    It has happened to me a few times where google search would suddenly use 40% of my battery. Has only happened over night.
    It also happened twice on my galaxy nexus 2 months ago right before I switched to the n5.
