    I bought note 4(nm-910c) 4 days back and I also updated to lollipop.
    But I'm not experiencing a great battery life.
    I had to switch mobile network to 2G(gsm)only and power saving to see my battery drain to 50% in 4/5 hours with only WhatsApp used in Wi-Fi. I can post the battery usage screenshot here.
    Is this normal?

    This is with 2G network, power saving and brightness kept at least.

    Must do a hard reset for batttery life to come back after updating to lolipop. Use Samsung Kies online to keep your files while doing hard reset.

    I dont necessarily think this is bad battery life. The OP says just 4 to 5 hours of use but the battery chart covers 11:00 to 18:00 so that's 7 hours . . Just a guess but it looks like 3 hours of SOT if not more based on the SOT graph. When screen isn't on the battery curve is fairly flat and the device appears to deep sleep (looking at the 15:00 to 17:30 range).

    Seeing other battery stats pages and getting a true idea of SOT would help. Then again, with LP it's even harder to figure out what the heck is eating battery now. Nothing beats having full access to stats through root.

    I'll try running a 100%to 10% discharge and post my graph here. I had hard reset,cleaned the cache after the update to lollipop too.

    I use 4G on my Note 4 and get about a day and half of battery life before I need to start charging it.

    To be honest I find the best way to figure out battery life is to start fresh with a full battery, connected to wifi, clearing cache in recovery, rebooting, unplugging and then letting the device sit for a couple of hours with screen off. On first wake, jump into battery stats and look at the list of services and applications to see what used battery the most. Easiest way to accomplish this is fully charge before bed then prep and unplug. Wake up in the morning and observe.

    While asleep the device shouldn't wake up frequently. If it is, tracking down the applications that wake it takes effort and patience. Rooted users have it easy since battery stats are more detailed with root permissions, not to mention more tools to handle wakelocks.

    That wake time with screen off is a concern. Like I noted above clear cache in recovery and do a clean boot. It's best to test on clean boot without ever launching anything, wait a couple of hours and then check battery stats to see what floats to the top.

    I don't have a battery problem with my Note 4. It's not rooted either.

    I'd say for adnanrider, you're getting a full 24 hours battery life with almost half of that being active usage, and over nine hours screen time according to the GSAM screenshot. In my view, thats quite good.
