[Q] G2 Battery Life Issue

For the past couple of weeks ive been having issues with the battery life on my G2. I used to get 12+ hours of battery life on it but now im only getting about 7 or 8. Ive tried recalibrating the battery, clearing the dalvik cache, and changing settings on certain apps but that hasnt seemed to make a difference. Ive noticed that at the end of the day, the android system takes up a huge chunk of my battery. Any ideas?

I've had the same issues as the builds of CM have gotten higher in numbers. The ROM that's given me the longest life is the stoock Gingerbread rooted ROM. I switched back to CM because oof the Text MMS & them always being Slideshow issues as well as no ability to stoop the phone from vibrating when I'm on a call. Same issue with CM too actually.
I'm bumping this because I feel your pain.

you can fix that in call settings you know!

Are you running CM7? If you are, open up spare parts and look at the battery information under Partial Wake. See if there's something tying up the system.

There are a few things listed but I dont think its anything that would eat a whole lot of battery. Should I be looking for something in specific?

Anything that's more than a sliver is eating the battery and keeping your phone from sleeping.

I'm getting 24 plus hours on glite which is aosp also. Maybe the battery is finally giving up the ghost. They do have a finite amount if charge cycles. If nothing else has changed and all things being equal to your 12 hour charge cycles maybe you could try a different battery.

Desire Standby Time Results

Hey all,
I just thought I would post this as I thought it was quite incredible.
I don't know what HTC's stats are on 'standby time' (which is usually how long a phone will last with no radio gear active) but look at how long my Desire lasted when I took the sim card out

That's 302 hours
Just Sayin'...

Another thing that I noted was the vast amount of 'awake' time vs 'screen on' time, sometimes lasting hours.
What does android have to do so desperately whilst the screen, radio, wifi, in fact everything is turned off??

Its not Andeoid really. My best bet would be that Go Weather app.
via xda app

I'm not entirely convinced that it is, I could uninstall GoWeather or do a /userdata wipe and retry to see if it'll last any longer?

Even if you put it on airplane mode, the apps you have would still try to wake up every now and then to try and refresh themselves. If you have a resource hungry app then it will wake your device to do the task it needs to perform. It may or may not be go weather app but there is something installed on ur phone that is keeping it awake even on standby. That's what I think anyway.
via xda app

Ha ha ha ha...looks about the same as my desire. I got one hour battery life on idle once with 3G off, wifi off and most of my user apps killed.
My phones been charging for the last four hours and it hasn't moved from 75%. It dies in ten minutes If I use the data connection when it's discharging.

Another battery drain with screen shots

Ready to go back to @??/€..... hate that but im sick of this battery drain randomly
Ive found a few things to be consistent maybe others can chime in.
With google services. Its not always bad. Recently had everything on and no issues. Including gps, Google now, location services etc.
I have found out to last more than a work day. Come home with 45-50%
But today..... Phone just restarted randomly, not the first time either. Usually there is an update for something and the phone restarts to update an app or whatever.
Today, just restart. Then 40 min to 1 hour later. Phone is getting HOT, I look and I had gone from 70% batt to 56 in minutes. Then to 40 then 15 and all the way to 2%
I wanted it to shut down on its own and restart it with a charge but, I had to drive home and car isnt 100% reliable and I didnt have a car charger. So I plugged it into pc to get a few % up.
Google plus went rogue I guess. As you'll see below. But why? And why doesn't @??/€ have this problem?
I just want the phone to last a full day. I dont even use it at work hardly at all with the exception of a bit of tapatalk and facebook......
Screen shots below for help.

Not to state the obvious, but have you considered freezing or uninstalling Google Plus?
Also, check out the link in my signature about keeping Google Services in check.

I forgot to mention that I'm on 4.2 .2 . In addition I didn't do anything to the song, I did not force stop loss, nothing. And everything is back to normal today

[Q] System_server: Excessive CPU usage & battery drain

Hey guys,
I've really liked this phone - until a few weeks ago.
I had the fated sudden decline in battery life. BetterBatteryStats has been on my phone for a while, so I opened it up and checked what usually kills battery on Android: the wakelocks.
It seemed totally normal!
Then, I checked processes. (These are today's stats, still just as bad)

system_server?
I noticed my phone was getting warmer whenever I was actively using it right under the camera, I guess which is where the SoC is. It's also been getting noticeably laggier.
Also today, under the battery usage in the settings:
Android OS and Android System are using twice as much battery as the screen.
This is pissing me the hell off. My phone drains perfectly acceptable battery when it's asleep, but take it out to use it and suddenly it's draining over 20% an hour. The extremely vague and obscure nature of the process doesn't help either. What does system_server even do?
I'm running Tweaked, and I've been alternating between ColonelX and Lean with no difference in battery.
I've also dirty flashed (really don't want to factory reset) to the NF4 Tweaked 3.5 beta. Only difference here is less lag.
As for bootloader, radio, and all that stuff, it's NF4 as well.
Nearly all Samsung bloatware is frozen in Titanium Backup, and all other troublesome apps have been greenified.
Attached is a log from BetterBatteryStats.
Thanks in advance for your help!
(I'm typing this on my phone, and battery had drained over 10% since I started writing this post.)

I had exactly the same issue since I upgraded my note 3 to Lollipop. It was fine when the phone was in sleep. But when using it, it drained the battery super fast...
system_server consumed lots of CPU resource at most time.

Phone always awake & massive battery drain

So I've had this problem for a while now where the phone would be awake for longer than my screen has been on. I would usually get around 10-12% of standby drain overnight.
But since this morning the problem has gotten way worse; the phone has been awake for pretty much every second with 20% overnight drain (I've attached a screenshot below).
How should I go about troubleshooting the issue?
I'm using the Indian variant with 6 gb and I'm currently on MIUI 10.0.2.

Battery Drain Because of Continue High Cpu Frequency Bug
Some Persons Solve this Bug in Miui 10.0.3.

Not solved!
I have also Redmi Note 5 global version with latest MIUI 10.2.1.0 stable and no root just unlocked bootloader and face the same problem!
A big thumb down to Xiaomi.
Maybe chinese try to spy people? Bugs like this should be addressed asap but it seems they are still in place, version after version.
With this big battery we should not face issues of this kind and have battery life over 2 days if this bugs would be resolved!
There a question in my mind: why the hell all manufacturers go for encapsulated phones where you cannot take the battery out??? Devices need current nonstop, even when they're off, for what??? Conspiracy?
Still, what we should do in order to repair our problems, without rooting if it is possible! I know rooting solves a lot of bugs but I'd like to keep it simple.

Something is running in background, try to figured out which app is awake by looking into running services under developer option and then close running applications
S.off your phone for 5 mins and then reboot your device
