Hello,
I noticed that the phone continues to use the battery a lot while it's in airplane mode and NOT awake.
For example last night I went to sleep and put it in airplane mode with 67% of battery, when I woke after 8 hours the battery was at 58%. It dropped 10% for no reason (with my other android device if nothing is on it never drops a point all day!).
Viewing the battery stats I see that the in those 8h the signal was off, the screen was off, wifi off, the phone was asleep the whole time but still the battery dropped. How is that even possible? What used the battery if nothing kept it awake?
I'm using cm7 KANG

I fully charged my ds7 last night, used it to surf the web for over an hour. When I went to bed, I turned on airplane mode and noticed battery at 71% before putting the ds7 on standby. When I woke up this morning the battery level was at 35%!!!! What's going on? I set power management to aggressive, to turn off all data after 15 minutes when screen is off. Is anyone else having this problem?
I have been watching my battery life daily after upgrading my stock wifi streak on Monday. First day after only adding a couple of apps, my battery went down 65% in 10 hours on standby. Loaded more apps and played around a lot and then put in airplane mode and turned off GPS sat and it dropped 23% the next day using same 10 hours in standby. Last time i kept sat gps off, in airplane mode AND turned off wifi, and it only dropped 3% in the same 10 hours. That was nice coming back to a 97% charged streak.
Draw your own conclusions. Obviously something is still draining it with wifi on.
A few times i noticed the screen come on when it was in standby sitting on the cocktail table in front of me. (wifi on at the time) So is an app doing that? or an account syncing? I dont have any answers.

Do you remember using Google maps? I noticed that Google maps does not shut down after you run it, it keeps running in the background and drain the battery.

First time(when it dropped 65%) yes. I remember opening Maps. Next day i went in and forced it closed.
Also forgot to mention in power management, i used standard but i set the times to 00:00 to 23:59.
Ok, I have a sort of answer. When the DS7 first got 2.2.2, it really seemed that battery life improved. But what I found were a couple of things that worked.
1. Standard Power Saver. I hate waiting for wifi as the DS7 wakes up.
2. Turn off auto-sync. I also have a DInc, so I am not worried about missing my gmail. (auto-sync will also run while there is no data service, often running the battery down quicker than when data is connected)
3. Turn off GPS. There's really no need for me to keep it running all the time.
4. Turn on Airplane Mode and then turn on the WiFi.
I can usually squeeze out about 6 hours of normal use in honeycomb with these settings. And definitely more when left alone overnight. But yes, the battery still does go down significantly.

DOnt forget about to remove the Phone.apk and telephony.apk fi yours is WIFI only
Recalibrate your battery and try juice defender it might work

I have stopped doing this as i found out that once the phone full charged ( leD green) , the wifi if ON is still conencted and running in full power mode and this seems to drain the battery , while the battery indicator is showing 100%!
when unplugged in the mrning, just a 1 hour or 2 hour use seems to drain the battery to 50% because the the whole night while it was conencted it was being used by the wifi
so now when i had the phone fully charged i just disconnt it and leave it to rest.
In th emorning the phone seems to behave normally and left with juice to last whole day even after 8 hours on sleep standby...
With a couple cycles of my battery and using the power saver, I have noticed a big increase in the the battery life. However, I typically turn my phone off at night and have noticed that when I turn it back on in the morning, I have lost 5% - 8% of battery life because my phone has stayed awake all night (see pics). I have attached some screenshots and highlighted in red the times when it was turned off. It looks like the wavelock keeping it awake is the HTcShutdownThread-shutdown. Is anyone else experiencing this? I would like to find a solution, as it seems my phone would do better with battery life if I left it on in standby, instead of turning it off. This should not be the case.
It appears to me by looking at the first screenie that the awake time is caused by your phone looking for a signal
The Network signal and the awake match up if they were put together the would make one continuous line
There was an update that addressed this.

The same fix also stops location from keeping your phone awake.
I am having exactly the same problem! And I don't know how to fix it!

Losing around 15% of battery whilst switched off overnight. The phone reads as being either awake with screen on or off.
Hi guys, I've a problem with my one.
Sometimes the battery percentage get stuck on a value for a long time, even if I keep stuff running (that usually drains battery). Tonight happened again in such a strange way..
The phone turned off yesterday evening at 0%, so I plugged in, turned on the phone, used another bit and than setted in plane mode so I went to sleep. I woke up in the middle of the night and noticed the green light so i took the opportunity to pull the plug (to avoid overcharge). This morning i notice battery percentage at 77% and battery stats with no app activity with cronology time on 32mins (I pulled the plug 4/5 hours before). Now I'm using the phone from more then an hour and it's still at 77%.
Is this an hardware or a software problem? I have stock rom update to lollipop version.
Do you know how can I try to solve this?
Also if i leave the phone unplugged at night it battery drops down 4/5% and in the battery stat i can see "standby 100%" with 100% of the time "without signal".. in the battery cronology wifi bar looks always active
My battery is draining by 8-10 percent during night in about 6-7 hours in stand by mode.
I have even tried switching on the 'maximum power save mode', but no change in battery drain.
That's not normal! Do you've airplane mode on or off?

it's probably a network issue, it happened to me as well, the network signal is weak on this phone i guess, something that helped is switching from (4g/3g/2g) to (3g only)
