I posted this in another thread, but judging by the lack of replies, I guess that was the wrong place. I have a SE Arc S with cm9, when I turn my phone off (last time I tried it it was switched off for 10 min.) the battery drains, and not just a little bit, but 40% easily. I've attached a screenshot, this was after powering down for 10 min.
What's causing this?

This issue may be due to incorrect battery calibration, i suggest you discharge your battery fully and then charge it to 100%.

There is no such thing as battery calibration for Li type batteries.
And are you sure, that your phone turned off properly and did not end up in a bootloop?
yes, I long press on/off button and chose "turn off", then it says "turning off" for a few seconds, then the screen goes blank, so I don't think it's a bootloop

Hi,
I've been using HTC Desire for 6 months and I got this problem lately.
First, please have a look at the battery icon. What does it mean?

Second, during the day use, my phone just freeze for no reason. And when it's freeze, the screen is totally off and the notification light flash 1 green, 2 orange continuously. Then I have to take out the battery, plug it in and turn it on to use. It just happens so randomly.
Third, it happened just now. I played game till the battery gone and left it on the table and went to sleep. But when I woke up, plugin the USB charger (I forgot the main charge at work) and it didnt charge. I turned the phone on and saw the battery icon was like what appears on the screenshot above. I turn it off and on again, the battery became full magically
So what caused all those is the battery? And sometimes when I use the phone for a long time when the battery get hot, it's freeze like I described as well.
Anyone got in the same case as mine?
No one knows?
For several past days I'm having issues with battery calibration. T700 drains extremely fast. When battery shows 0% device turns of...OK but when I turn it back on it shows 37% ?!?!
How to solve this?
Using stock rooted ROM.

Did you try to reset your batterystats.bin file?
There is a lot of discussion if it actually does something or not.
But in your situation maybe worth a try?
Google for it if you want to know how it works. There are a lot of tutorials for that.
i ll give a shot

Hi,
I bought this tablet (Tab S 10.5 LTE, model number T-805) on September 2014. In the last month I'm experiencing weird battery behaviour, like the one in the screen attached. I had about 50% of battery charge and I started a game like Angry Birds 2.
In a matter of minutes, the tablet warned me that the battery charge was under 15% and after another minute the under 5% charge warning message appeared.
Questions:
1) is the tablet battery already worn out? Do you know if Samsung European warranty cover battery problems?
2) Before sending the tablet back to Samsung, should I try recalibrating the battery? I have an old power adaptor with 5V 0,7A (or 5V 1A), should I try a a "slow charge" to see if the battery situation improve?
I have the latest firmware, lollipop 5.0.2 and I did a factory reset after the update.

Do a battery re-calibrate is the first thing i would do.

Thanks Thinderbox, I'll try with root and battery calibration.
Update: after a battery calibration discharge rate of the battery seems back to normal. Thanks again @Tinderbox (UK)!
Hello everyone, yesterday I picked up a brand new Galaxy s9 exynos version. At the very start, the battery gad around 42 procent, it lasted me about 2 hours till it went to 10 percent. Later I charged the phone to 75 percent, went out with friends, and after around 35 minutes, doing nothing in my pocket, it dropped 4 percent. After some heavy usage, I decided its time to do a full charge for the first time. I will post the screenshot down bellow. I've heard, that its just the first day, and it will get much better after around a week, although im a bit affraid, that the battery life wont improve. What do you all think?

You are meant to charge it as soon as you get it 100%. You need to calibrate your battery now and maybe do a factory reset.

Don't worry about factory reset, just drain the battery to 0 then charge back to 100 for the next few charge cycles
