Why do I have such a massive battery drain on my HTC One M8?

Massive Battery Drain on HTC One M8

I had previously owned a Samsung Galaxy S3. A few months ago, I started thinking about buying another phone. After tons of reviews read, I decided to buy a GS5. A pretty good phone, only some Touchwiz lag, and some overheating. 3 weeks ago, an idot broke my phone. I sent it back, and I had the possibility to either try to repair it, or replace it. This took a week, and I was annoyed of going around with a Nokia, so, at the advice of a friend, I replaced it with a HTC One M8. I like this phone very much, but I have only a problem, the battery level drops very quick, or at least this is my impression. At the end of the day, after moderate usage, I have 30% left, while on my GS5 I had 60-65% left. I even saw an YouTubers M8 resisting for a weekend with moderate usage. And that wouldn't be such a problem, but when I am using it, the battery level falls dramaticly. In the morning, after 20- 30 min of browsing Internet, some Facebook and maybe sometimes a short video, it falls from 100% to 90%. My friend, that has a M7, leaves from school with 70-80% battery, after he uses it pretty much, with 4G and NFC activated almoust all the time. Is it normal? I love this phone, but I begin to regret that I made this change. Down below I will put some screenshots ( they are not my best, I deleted the other ones from mistake) Thank you for your help!

Condition the battery. Turn the phone off and charge the battery until the phone tells you to unplug it. Let it rest for 5 minutes, then plug it in again until the phone tells you to unplug it or 15 minutes, whichever is longer.

Use the phone until the phone tells you to charge it. Don't charge it until then. At that point, either turn it off and charge it or turn it off until you can get to a place you can charge it for a few hours.

Repeat that cycle for a total of 3 cycles.

Your battery usage statistics (what app is taking what percentage of the total usage) seems not only normal, but abnormally low. Android OS and Android System usually eat a lot of battery the first few days. (Although that could be because WW2 is using tons of battery - it's your single largest battery drain, and the phone wasn't off charge that long.)

BTW, for longest battery life (which you should be especially concerned with since you can't easily replace the battery in that phone), charge at the 40%-60% point once you've gone through the 3 conditioning cycles. NEVER let the battery get below 20% - shut it off if it gets that low, unless you have to call 911 to save your life. (Better to save yours than the battery's.) Choosing between someone else's life and the battery is your choice.

install GSAM and post your screenshots... I had a bad battery and swapped it for a new one that has been much better...

GSAM will not give accurate results when it is first installed, it has be used for at least one week.

Try turning off location reporting and location history. They are big battery drainers.

I am rooted and I use BetterBatteryStats. It shows kernel wakelocks and partial wakelocks.
