    My less than 2 months young LG G2 battery drains very fast. 90% battery level before 12 midnight, 35% remained at 8 o'clock in the morning. I only received 15 Whatsapp text without graphic or video over night. What makes the battery drained from 90% to 35% while I was sleeping ? Do I need to turn off some built-in features that are battery hungry ? Does it matter I keep my phone on 24 hours or should I turn it off during the night ?

    Go in settings, general, battery click on expected time remaining and it will give you a list of apps that has ate the most percentage of battery. Mine was google play services. I did a factory reset. Dont update the google maps because that seemed to be the cause of my problem. Hope it helps

    The performance that you're getting definitely isn't normal or typical for the G2. Most people(me inc) have found it to be rerally efficient in standby mode. It will typically drain about 1% per hour if you've got location services and wifi off

    Do you have good cell service? Poor signal could eat a lot of battery, but that still seems extreme.

    Install wakelock detector to see if you have a wakelock issue. Then use Greenify to hibernate specific apps.

    I turn off GPS and battery back to normal. Why GPS is so hungry ?

    Likely because your phone can't find a GPS signal indoors so is constantly trying to search for one.

    I use "battery saving mode" and it really does work great for me. May be OP should try this if on 4.4.2.

    I have always turn my phones off at night, if someone really needs to call mt they know my home phone. Also I only turn on GPS when I use maps only.

    I just mentioned on another post... battery has been much better since kitkat where it's been very consistant and idle drain improved... I just unplugged last night went the full night and then some 12 hours at 100%. This phone has been the best I've ever had as far as battery life and usage time goes. Best phone I've had to date really.

    Sounds like OP has app installed thats causing it. I'd reset and test baseline. Also, curious what carrier you are using?

    Do you have hangouts installed and do u use it? My battery was AWESOME until I started using hangouts frequently. Google play services just raped my battery. after uninstalling hangouts my battery is mostly back to normal.

    vzw stock Rom 422 xposed. I use greenify on some apps and was getting about 30 hrs total life with 3+ hours screen on time before installing/upgrading/using hangouts and about 12-15 after. Google play services would consistently be responsible for 40% battery consumption with 5000+ wakes. the next closest would be android system with 500 wakes and 25 to 30% battery...

    this is all with the same usage habits.

    imo hangouts and other Google apps destroy battery life. after uninstalling hangouts my battery life immediately returned closer to normal

    My G2 battery life used to be great. But after recent Google Play's update, it effect battery life. It drain very quick and also getting hotter easily.
    I hope LG realize this and launch update patch very soon.

    I have battery saver switched off but battery life on my G2 is outstanding. I don't use any battery saving apps either. Used to use juice defender but discovered that the app in itself actually uses up battery especially as you have to keep it running.

    I fully charged it the other evening and went to bed. In the morning it was still showing 100%. All my other phones used to go down by up to 10% overnight. A lot does depend on how good your phone signal is. If you have a poor or no signal, your phone will constantly be searching for a signal which uses up battery power. I noticed this when I stayed in a hotel for a few days were there was literally no phone signal. My battery went down about 12% overnight. The lack of signal was reflected in the cell standby percentage which is shown in the breakdown of percentage battery use. Usually it's the screen which uses most battery but the cell standby was leading the way with a whopping 80%! I would suggest that if you live in a poor signal area, either put your phone in aeroplane mode or switch it completely off overnight.

    I also have location and synch switched off and also set the background process limit in developer options to no background processes.

    Over the last month I had the same problem. I found it was AT&T carrier IQ according to better battery stats app. It pushed me to install a custom rom (port from G3) onto my phone and now my battery is amazing. This past weekend I got 46 hours with light usage.

    my lg g2 vs980 I've had for 7/8 months...at first the battery was like extremely good for the first two months ,I'd be at work all day and use it here in their wifi was on Bluetooth always on and it would be like 93%when I left work for a 10 hour day and I get up at 6...recently my screen broke and I had to order a new one and put it back home now the battery seems to be draining like crazy I don't know if that has anything to do with it or if it's just a coincidence but I know one thing I have to charge itat least twice a day sometimes 3 if I'm going out later. I've been through the battery I don't seem to see anything anybody have any ideas I recently unlocked the developer options right before the phone broke but didn't change any settings
