    Default Nexus 7 LTE battery life.

    So I have had mine for about 10 days and overall very happy with it.

    The battery life however is bugging me, I am used to my iPad Air which gets an easy 15-16 hours of usage and 3+ days of stand by.

    I am not exactly sure how to compare but if I take the screen on time of the Nexus it is around 8 hours and total off the charger time almost two days. The iPad battery is much higher capacity but that should be offset by the bigger screen.

    What type of battery life do most of you get and any particular app/s that you find to be the culprit. Here are the battery stats, can someone tell me what can be improved?

    Thanks much.

    Yes I am since cost has nothing to do with battery life only the efficiency of the system matters. Trust me on this I am an Electrical Engineer and get paid for maintaining and improving system efficiency.

    As far as that goes the Nexus is definitely as efficient as the iPad. As a matter of fact I had the Moto X until recently and the battery life on that was pretty close to that of my 5s. That is a $350 device vs a $750 device.

    I am sorry I came in here asking for help and so let's stick to that please.

    Thank you

    Yes I have and also I am not really new to mobile devices so have tried most of the common culprits. . I was hoping someone with experience of the N7 could give me some pointers from my screen shots
    I have been a member here for awhile though don't post much, I do believe the forum has changed for the worst unfortunately.

    WOW! some really snippy banter going on.

    Just for the sake of being thorough was the iPad also on a mobile network or was it wifi only?

    My Nexus 7 (2013 wifi only) has tremendous idle time, does really well surfing the web but if I decide to play a game for an hour the battery just gets decimated.

    Also, this forum has not changed for the worse. I have no idea why you are being attacked for asking a very reasonable question but I am on your side on this one. Personal attacks are just not called for.

    My Nexus 7 gets about 4 hours of battery life, not as much as iPad but quicker to charge, not the same price.

    Thanks finally

    Yes they are both LTE and both on AT&T. I also tried the Mini retina before I got the Nexus and that seemed to have better battery life than my Air.

    Now the Mini was WiFi only so not a proper comparison.

    Thanks, for bringing it up, I should have mentioned it.

    My only other thought is that it is common for people to experience very poor battery life after taking a system update. From your batters status shots it doesn't look like anything fishy is going on but clearing your Dalvic cache might help (Shouldn't hurt).

    Oh good, I am glad nothing looks fishy. As a matter of fact I got two updates on it as soon as I powered it up, so that could definitely be.

    I will give cleaning the Dalvic cache a try.

    Thanks very much for all your help.

    I was going to suggest adjusting the screen brightness to a lower setting to see if that made a difference. Some people like a really bright screen,though.

    I don't have any screenshots to post at the moment, but I've been quite happy with the battery life of the N7 (2013, Wi-Fi only). Seems like I get about 4 hours on a CPU/graphics intensive game like XCOM http://market.android.com/details?id...2kgames.xcomeu and probably 10+ hours reading ebooks (with the screen at minimum brightness).

    I'll try to get you some hard data after the next charge cycle.

    Ladies and gentlemen, I really hope that I never come into a thread like this with a new member asking for help on their new device being met with trolling, ridicule and just straight up stupidity. Same rules as always: if you don't like a post, ignore it.

    Thanks, I don't need it really bright but do need it a little higher.

    My major reason for getting a small tablet was the ease of traveling with it for work. Most if these are construction sites and do not have adequate or dependable power.

    Also a reason for my obsession with battery life. Lol

    Charlyee, that looks from your screenshots like very reasonable battery life for the LTE Nexus 7 2013. You are using about 10% per hour with the screen on and about a third to a half percent per hour with the screen off. That is consistent with what others report.

    Please accept our apologies and welcome to the forums. I hope you get some more of the answers you seek.

    I have the Nexus 7 (2012) version myself and have had good things to say about the battery life at least for myself. That doesn't mean its the same for everyone and it doesn't take much to cause a severe drop in battery life.

    Thanks, that is really good to know. I will just have to plan to get it charged sooner than waiting until its about to die, yeah I know not good for a Li-Ion battery lol

    Fortunately as someone pointed out it charges much faster than the iTablets.

    Apology not needed, I shouldn't have judged a forum based on one person's confrontational attitude.

    Thank you so much for the welcome.

    Yes all the other posters so far have been extremely helpful and I very much appreciate that and learned quite a few things already.

    I do like mine very much, I bought and returned the iPad Mini and the Toshiba Encore 2 before this and am really glad I found what was looking for.

    Thanks again for making me feel welcome.

    Maybe even consider purchasing one of the many types of portable " juice packs " on the market today. Should give you that extra juice you need to get thru the rest of your day for cheap and they don't take up much space at all..

    While I am at home yes, but not at some of the places we get to stay during construction. I would be worried about setting the place on fire or blowing up my charger. The power situation is not safe or dependable in most cases.

    WiFi was the biggest battery killer for me. If I'm travelling or watching a movie, I always turn wifi off and it will significantly boost battery life. It seems like its always searching for a signal and constantly updating apps.

    Your battery life doesn't seem that bad considering you have the LTE version.

    About the battery life on the iPad, Apple produces their on hardware so their software optimization is much better then on Android, which results in better battery life.

    Also Taylor from Pocketnow noted that idle time on most of his android tablets sucked, but the iPad has always been consistend.

    It really depends on the user, some people get great idle drain and some don't. If you really value good battery life you just should stick with the iPad. But if you want the best bang for your buck and you can deal with the battery life issue's (sometimes) just stick with the n7

    Thanks, yes good point about Apple. I really like my Nexus, the size, the zippyness etc. As long as I know that there is nothing wrong with my device I will just have to train myself to charge it sooner than I usually do.

    I have two iDevices already and the N7 is a breath of fresh air.

    BTW, does any if you turn your N7 off at night or from time to time? Is this recommended?

    Well, a factory reset won't hurt either to find out if there is something draining your battery, or maybe try safe mode and let it sit for a while. Also wiping the cache partition could help.

    And since your using a mobile connection, signal strength has to do with the drain too. A bad signal equals more drain per hour.

    And if you really think the battery life sucks and you still have warranty, just send it back to Asus and ask for a battery replacement, see if that makes any difference

    About turning off at night, the only thing I do with all my devices at night is just, set them in airplane mode, that saves some battery too.

    You can however reboot it once a week or something, i.m.o if my drain is not weird I live by : If it ain't broke, don't fix it, haha.

    Anyways I understand were you're coming from. I'm a battery freak myself haha, and their are just too many factors too really tell if you have good battery life, it ultimatley is your decision if you're happy with it or not

    Thanks everyone, my battery went from 97 to 82% overnight, that's around 8 hours. You are right I need to decide if I can live with this.

    I will try putting it in airplane mode at night and see if that helps.

    Short story...
    I had an HTC thunderbolt, the phone with the worst battery performance of any modern smartphone ever released. After I upgraded I put the phone in airplane mode and let my kids use it on WiFi for games/YouTube. With the radio off is was getting 3 days out of a battery that used to need a charger every 4 hours.

    Moral: you might just need to put the nexus into airplane mode when not in use. If you don't need to receive notifications on it maybe a battery optimizing app could be used to turn off the mobile radio whenever the screen is off. I have never used one of those apps but I bet if it works and you don't need to receive notifications like texts and instant email alerts you will probably see a significant gain in battery life.

    Based on the battery drop you reported with the phone idling a am pretty sure its your mobile radio eating up battery.
