I use Havoc OS 2.9(rooted). I bought a fast charger (Output 2.5A/9V = 2A/ 12V=1.5A) just yesterday. It charges from 50 to 70 in about 10 minutes.
I charged it from 30 to 65 before sleeping. And when I woke up, the battery had drained 15 % in 7.5 hours.
What can be done to avoid these battery drains?

Got my rezound battery in a couple days ago and so far its not so good. Gave it a full charge out of the box and then bump charged it. Wiped battery stats and then ran it hard to drain it dead till the phone shut off. Recharged and bumped it again. It will hold at 100% for a good while during use but then drops drastically. Sitting doing nothing it dropped to 60% in about 2 hours. Then listening to music it went into around 20% in 45 minutes. Charged it overnight and today sitting doing nothing it was down to 30% in about 4 hours. Put it back on the charger now its only charging to 88% and stops. Am I doing something wrong here or is my battery a dud.
Update
after the charge to 88% I have used the crap out of my phone tonight and more over the last 4 hours. Surfing on WiFi, music, and running repeated benchmarks. The battery had sit for several hours off charge and dropped from 88 to 52% while sitting unused. Dropped from 52 to 35% over a few hours of music and 4g web browsing while driving my wife around shopping. After I got home and started using it stayed at 35% for over 2 hours of use and has dropped down from 35 to 28% in the last hour or so of continuous use. Seems like its holding a good charge, but just not reporting battery stats correctly.

I have had the Rezound battery for several months and at first it was reporting the battery accurately, a longer usage time, and no complaints. I would go down to about 5% and then I would charge it.
The last few months have been erratic. The battery could show anywhere from 15% to 25% then just shut off completely. This has become very frustrating and unreliable once I get under 30. I downloaded a battery calibration app that has proven to be worthless.
I was on vacation last week and found out something interesting. If I charge the battery to 100% then take it off for about 5 minutes and reboot the phone it will show that it is charged to somewhere between 79% and 84%. I can let it charge again to 100% and get a full charge that time. I tried several times doing battery calibration and it seems to make no difference. I think the default stats file is limiting the charge to the stock battery capacity somehow. I know the stats file gets written on boot and I found a post on here somewhere about HTC releasing an update for their extended battery after its release due to it not charging completely. I wonder if the rezound battery and all other extended batteries that aren't the capacity of the two official ones could perform better if they had modified stats files. Without the reboot and additional charge I am averaging 16 hours roughly per charge. With the additional charge I have gotten over 30 hours on one charge and get at least 23 hours. Last full charge was 27 hours 38 min and still had 16% charge.

Finally broke down and got one yesterday from Big Red. So far, on initial charge (off wall charger), I'm @ 38%, 15 hrs, moderate use. For me, it's an improvement over the stock battery. FWIW, once I popped in the rezound battery, I wiped battery stats in CMW....

My rezound battery was doing great until the first weekend when I had to switch it with the stock thunderbolt one on the fly. Since then they seem to perform, at best, the same - but usually it seems like the rezound one lasts even shorter than the original.
RE: Idle Battery life - Solutions?
Hello,
I've been using my Nexus 7 very little this week. But since I stopped charging my current battery stats read:
1 day 11 hours and 57 minutes on battery.
Tablet Idle (39%) for 1 day 11 hours and 26 minutes.
Aside from that I've had 25 minutes screen time and 20 mins Wi-Fi use.
I'm currently on 71% Battery. Does this seem like normal battery usage? I would have thought the idle tablet could keep it's battery better than this.
Any tips/thoughts on if this is normal?
Thanks

Make sure Wifi, GPS, and Bluetooth are off. They drain the battery quite nicely. Another tip is turning off auto-syncing for Gmail, etc if you plan to keep the tablet in sleep. Other than that, the usage seems within normal range, maybe a bit over.
Then again, why not just turn it off? It takes about 10 seconds to power up...
Guys I had a problem and I hope you can help me with it
I bought an HTC 10
It charged 32 % in 30 min I was so frustrated
So I tried a fully charge it and fully drain it and it successfully charged to 44% in 30 min but then I charged it again at 3% and not fully drain it charged 34% again
I am so upset about it
Is there a problem or what?
Guys m notificing serious idle drains like
I just charged my phone to 100% usd for few sec n then i kept my phone idel for an hour m battery was 92% hell no ..
Also same day at night battery was 88% i close data wifi n all n in morning it was 72%
Whats this something is draining my battery
Battery drain from 100% to 90%
I got this phone last month and yes it's happening here too. When I unplug the charger after 100%, it drops down to 95% in 10 minutes, then to 90 within a few more minutes.
After that it works fine. I've noticed the same 10% drain happening even if I don't charge it fully. Even if I charge 70%, it goes to 60% within half an hour.

I second this, been really frustrated about my battery from last update; been waiting for Pie patiently, hope that improves things and kicks in development.
Hi all,
My phone drained 14 percent battery yesterday while idle for 9 hours. The interesting thing is when i add the mAh usages that i see in battery and performance tab it only adds up to 6 percent battery usage. ( i calculated and confirmed with time that 40 mah is aproximately 1% battery)
Also this morning i am seeing an unusual drain as well while the screen is on, it drained 5% but it should have draned only 3% because it says it drained 138 mAh.
Does anyone have any idea about this problem?
This also happened 2 weeks ago and the only thing common both days were, i charged my phone slower (charged using usb on the car) instead of using fast charging.
I also leave the screen shots that shows the battery usage.
