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.

Hey all,
I took my N1 out of the charger 5 hours ago. I checked 1 website, that took like 1min. I've been voicecalling for 25min and 4s (had the speaker active for 4 minutes). That's all I've done with my phone. All the other time it's been idle with it set to use 2G only to save battery (I'm in an area where 3g is weak, so it keeps switching, and I heard that kills battery quite a bit, so that's why I set it to 2G only, correct me if I'm wrong on that).
Now my phone only has 15% of battery left.
I can't imagine this is normal, so my question is: Is this normal? If not, what % of battery should I have left normally after 25min of voicecalling?
Thanks in advance.

Do you have any background apps that are refreshing a lot? What's the screen setting while on a call (how long for the screen to turn off), does the screen stay ton while on speakerphone? Are you sure you were at 100% when removed from the charger? GPS? bluetooth?
No idea how the battery couod drain that quickly without at least a couple of these things being some sort of a role.
Sorry, forgot to mention those things.
- No things running in background. Just mail checking once every hour.
- GPS is on, but normally that doesnt drain my battery at all, can leave my phone idle for 12 hours and still have 80% or more left.
- Screen is on auto adjust, and it wasnt bright at all while I was using it, when i normally use my screen I can use it for at least 2+ hours before battery is at 30% or less.
- Screen was on during the speaker, but that was only 4min. The screen does go off when I'm calling without the speaker on.
- Yes it was at 100%, I'm 100% sure.
- Bluetooth is off, wifi was also off.
I've had problems with the phone draining during phonecalls with the same length of talk time.
That, or playing movies/youtube, but i can understand why that would happen.
What ROM are you using?
After i switched to the undervolted CyanMod Rom, it helped with battery length.
I'm running the stock ROM with update 1.
As an extra note, I tried to start the camera, but it didn't want to start. Not even after multiple tries.
I don't know if that has anything to do with this problem.
I've been posting here as well, there's some extra information as well: google.com/support/forum/p/android/thread?tid=3b2399fce53a8f2a&hl=en
run your battery completely dead... like when your phone turns off open the boot loader and just kill the thing till you cant even get the boot loader to come up...
take the battery out wait a few seconds to make sure all the extra juice has discharged in the phone and put it back in...
start charging again and dont turn it on until it is fully charged (green light should show up and then wait smore after that)
I've turned everything off (Wifi, GPS, Sync, brightness, and autorotate by mistake) in an attempt to increase my battery life just like everyone else. The only item I leave on is Bluetooth for my car. The last couple of days my phone lasted all day. I can live with that.
This morning I went onto a web page and turned my phone sideways to read the screen a little better and it didn't flip. That’s right I turned the autorotation off so I turned it back on. Use the phone and set it down. I picked it up about an hour ago to check an email and the battery level was at 68%. At this rate I'll need to charge it sometime after lunch.
Could this feature be draining the battery this much?
Just an observation that seemed strange to me.
I would have never guessed that it would use that much battery. I assume it is constantly looking at the sensors which could be leading to the increased battery usage.
Leaving it off seems to be helping me get through the day without charging.

My battery life seems pretty similar on perception, I'll be running without auto rotate for awhile to check the graph. Will let you know. FYI Screen Filter has made my battery last an extra few hours+.
it could just be that your battery meter is not reporting the percentage properly. an easy remedy for this is recalibrating the battery by allowing it to discharge completely until it shuts off and then proceeding to charge it back to full without unplugging it. autorotate is definately not a battery drain, but the screen definately is.
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'm getting a regular wakelock labeled msm_hsic_host. I thought this was related to the phone's radio, but I turned on airplane mode and the wakelock continues. Anyone know why?

You probably have a rogue app polling for a radio signal and putting it in airplane mode is making it worse.
The same wakelock doubled my battery drain last night. I had it in airplane mode overnight. Going to leave the signal on tonight and see what happens. I was getting between 3-7% but it was 15% last night.
Tested it again last night. Unplugged at 4pm yesterday and used 5% battery overnight. I just hit 24 hours with light/medium use today and battery is at 75%. I know others have shared this but battery life has certainly improved with time. The wakelock is certainly reduced leaving data connected overnight. Hope this helps.

How are you able to see wakelocks without root?

GSam battery monitor has an option at the bottom that looks like a vacuum. Its called app sucker. Once that screen opens there is a drop down menu at the top that allows you to see the kernel wakelocks. Then you can select each wakelock and the next screen has a button there to google it. Hope this helps.

It does! I'm used to better battery stats, and still learning gsam. Thanks!
Looks like it's a big problem for alot more phones. I have the same wake lock also. I get about 1% per hour by leaving it overnight. Is that normal?

I think it is. But alot depends on your settings and the strength of the cell connection. Actually the cell connection is about the biggest battery drain that I have. I use Tasker on my phone. It disconnects my cell connection when the screen times out and limits anything running in the background. Calls and texts still come through. When the screen wakes up everything reconnects. Some would say the settings I use are extreme but I get good battery life from it. Tasker can be difficult to start at first but there are some good youtube how-to videos. Im hoping the new battery saving feature in lollipop will make it unnecessary to regulate any settings. I guess we will see.

This. I use tasker to turn off data and auto sync when I go to sleep (because its literally a waste of battery) and I got 0% to 2% drainage overnight (total, not hourly) but that was with a custom rom. I expect 0.5% to less than 1% per hour with this phone because at idle with 4g on I drain about 1%/hr
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
