    Does that occur frequently, or just this once? Sudden battery level drops can be due to a dendrite--see this article: http://forums.androidcentral.com/amb...tery-shot.html

    I just read the article but it's difficult to follow for a phone that has a non-removable battery. Also, my phone isn't even a month old... I faced this problem on Lollipop on the same model but a different phone but the sudden battery drop didn't repeat itself. and happened only once.

    Hopefully this incident won't repeat itself either... But the last date for exchanging this phone is on 29th of this month. So if there is any sure test I could perform to confirm whether or not the battery is fine, now is the time to do it. Please advice me on what to do...

    I'm not sure of any way to replicate that problem, so you're in a difficult position--if the store is willing to exchange the phone without any clear defect, then definitely try to do so. But if they require proof that the phone is malfunctioning, then it might be a tougher sell. The screenshot might be good to show them.

    The concerning thing to me is that the sudden drop occurred while you were still charging.

    Yeah I found that strange too... But it happened with my previous moto g2 while charging too...

    EDIT: Sadly, here in India, Motorola maintains a list of phones having unlocked bootloaders, so they'll have me on record even if I relock the bootloader (I'm guessing, correct me if I'm wrong). Rules out a return?

    Sorry, I don't know the answer to that.

    Are you using the charger that came with the phone? It might be worth trying a different (and reliable) charger.

    This has happened again. But after I restarted the phone the battery level came back to normal.

    This difference is that the last time this happened I was running Kitkat and this time I'm running CM 11

    I had the same issue a couple of times when running kitkat. After lollipop never happened again. I think there's some calibration bug causing this and another funny glitch, with airplane mode having a false battery drain.

    I think it's related to partial battery charges and enabling airplane mode sometime afterward. For some reason the Moto G doesn't like those two things happening the same day

    But the first time it happened with kitkat, restarting the phone didn't restore the battery indicator to the normal level.

    I had this issue on lollipop as well (on moto g 2nd gen itself) but I had that phone replaced. So if you count, I've had it on Lollipop, KitKat as well as CM11 lol...

    Ok so I had this issue once again. The phone was on around 64% and suddenly fell to 1%. Restarting the phone brought the battery % back to normal. I read that the solution is to charge the phone all the way to 100% and I did so last nightbut there was some battery drain even after I went to sleep and the phone wasn't even touched for 6 hours. Here are the screenshots:

    PS: Does the speed of WiFi affect battery usage? When my phone was connected to the WiFi, there was a huge download going on in my laptop so that download was taking up most of the bandwidth.

    I don't see anything wrong in your battery stats. It's quite difficult to know if there's something wrong after using your phone for such a little time. Much better if you wait until your battery has 30% left or so. 6 hours since full charge and 10 minutes SOT is not terrible for just 7‰ of your battery juice.

    About the slow WiFi. I don't think that's going to make a big difference. Just that your screen will be on for a longer time waiting for the data being loaded.

    Oh, it's just the sudden dip in the graph that got me concerned... An update is available for the ROM I'm using. I'll try it and see what happens...

    Also, what do you have to say about this:

    As I said before I had the same issue a couple of times and it's a very well documented bug in the Moto G forums. Never happened again after Lollipop. Maybe your CM version shares the bug with kitkat.

    Strangely enough, I've faced this issue on stock Lollipop as well. Now I'm not on CM but a ROM that is based on CM. Also, there are times when the battery graph just dips randomly (like in post #12 first and second screenshots). I've made inquiries on the XDA Thread of the ROM developer. Let's see what he has to say about this...

    Ok so I thought that I'd use a ROM for at least a week before trying to figure out if the battery is working fine. Here are a couple of screenshots...

    Those screenshots look perfectly fine to me. From the graph, you can see the battery depleting rapidly during the times when its "awake" and when the screen is on. Then it levels off (presumably) overnight when you're asleep but there is still some drain due to WiFi being on and Cellular Network being connected which is also completely normal. You can reduce this by putting it into airplane mode, turning off WiFi and Bluetooth etc but the amount you save will be fairly inconsequential compared to the amount that gets drained when you start using it through the day. You look like you are going to get over 24 hours and you already have roughly 3 hours screen on time so not sure you can expect any more from any phone.

    The sudden drops in battery life highlighted in previous posts is something I have had on both the 1st gen Moto G using KitKat and my current 2nd gen Moto G with 4G using Lollipop. I suspect its a bug somewhere and it did seem to occur when I had been charging frequently and not up to the full 100%. I now try to do a full charge to 100% and if that isn't convenient then I don't worry about it too much and just wait until a time when I can do a full charge. I suspect the phone's battery stats are just not always accurate hence the issue with it suddenly appearing to drop massively. Probably only once you do a full charge do the battery stats get updated accurately.
