    Hey guys I've noticed something odd on my HTC one m8's batter drain. I have the gsam app installed and I checked on the battery drain section and it stated that the kernel(android os) uses up most of the battery, anyone know what this means? I have some screenshots to help...thx

    That's normal. The system is usually going to be responsible for a good portion of battery usage, because the phone needs the system to run.

    If you think you're having abnormal battery drain, a couple of things to focus on would be:

    1. Poor cell signal. You have only one bar in that screenshot, and your Phone Radio is using 12% of battery. Some of this may be due to having to strain to latch onto a weak signal, which can use more battery.

    2. GPS can be a battery sucker--turn it off unless you absolutely need it. Change your Location Service to Battery Saving (which uses only wi-fi or cell signal to estimate your location).

    3. NFC might use a bit of extra battery as well. If you never use it, turn it off.

    Thx the poor signal strength is a result of living in the woods but will poor signal strength damage my battery or cpu?

    No, it doesn't damage anything--but it can lead to increased battery drain.
