So it seems like I have a defective battery but I wanted to ask if anyone else has experienced similar issues that may lead me to believe that this could be a software issue.
After unplugging my phone from a full charge it takes approximately 2 hours for the battery to report anything other than 100%. And when it does change it drops all the way to 80%. Nothing in between just a sharp drop. Sometimes I even see the battery gain new life and the percentage increases.
I am using the extended control widget to monitor my battery, but even the battery panelin the settings menu reports the same. I have played around a bit with temp rooting my phone, but these issues pre-date my first attempts, so I'm fairly sure that isn't the cause.
So before I call HTC or T-Mobile to get a new battery, has anyone else had the same issues with their G2?
I don't think its a defective battery. I, and I think almost everyone here, have same the issue.
I just notice after 4.3 update, my battery life suffers a lot. When I check BBS, the main culprit is surfaceflinger. I know its all about the display it shows in the screen but how can it eat almost all the power? Max screen time I get is 2.5 hours. Anyone experiencing it? Last post regarding this says its normal but I have my phone for the longest time but I think the drain is not normal.
My Samsung Galaxy S5 started having battery problems after the Lollipop update. Since many users has reported the same thing I downgraded to KitKat, which included a complete wipe of all apps, but that did not change anything. Maybe the Lollipod upgrade had nothing to do with this?
I did a comparison with my SO's identical phone. I fully charged them, put them in Airplane mode and let them be for 100 minutes. The results? Her phone had 96% left. Mine had 82%. **Four times** as much battery used! Battery monitors report nothing except that the screen and the android system uses most of the battery.
Another unusual thing: normally the phone automatically shuts off at 1% but now it shuts itself off randomly at 2% to as high as 12%. Battery calibration out of order or a dying battery? No, because I switched the battery with my SO's and I still experience the same issues.
I still have warranty left, but we all know that would likely mean I will be without phone for a month so I want to try everything I can first. Does anyone have any suggestions on this issue?
Subject of this thread is listed as a major kernel wake lock at times for me. Anyone know exactly what that is?

I just started seeing this wakelock also. I haven't changed anything lately and it just appeared. I hope someone has an answer.

I just started getting it since updating to 6.0.1 PN. I switched to AK Synapse and it drastically reduced it, but it is still there. Only info I can find is much older phones. I am using an LED manager...wonder if that could be it. May freeze it this week and see.

I believe that wakelock is from charging. I don't know why but the device doesn't seem to register as deep sleep with better battery stats when fully charged and then idle but still plugged in. Likely an issue with the program and not the phone.
However if you want to test this simply charge your phone over night. Once it hits 100% it will stop charging at some point and go into sleep mode. The device is still plugged in but won't charge anymore. Device will use power, mine is usually around 95 or 93% when I fire it up and use a little juice in the morning. During this time the device uses battery quickly until it drops to 89% or so then normal discharge rate. This is normal of most android devices I've had and most everyone here is aware of this:

Getting back to the wakelock issue, f you check better battery stats this wakelock shows up under the above condition. You'll notice the time on this wakelock is usually the sum of the device on but screen off time and your screen on usage or pretty close to it.
Now charge your device to full while waiting for it (as in not going to leave it for 4+ hours on the charger after it is full). Once it stops charging at 100% pull the device. Use as normally.
Now the device is fully charged. Really this time and not just the UI telling you it's full. When you use it throughout your day and then check better battery stats you'll notice the wakelock is no longer there or nearly so depending on how fast you got the device off the charger after it was full.
End result is this seems like a reporting issue with better battery stats or the device not fully going into deep sleep while being plugged in. I would tend to lean on a reporting issue as discharge time seems about normal at 1% or so per hour while idle and that tends to hold true to my regular doze discharge.
TLDR:
This seems more like a reporting issue than actual wakelock. Any significant battery drain when fully charged can be explained by the link above and testing as I have explained in the post.

The only thing is this wakelock doesn't start until after I unplug it and leave for work. It grows during the day..so is it faulty reporting? Something is using my phone when idle for about 2 hours a day with screen and sync off at 384 Mhz and that wakelock usually shows at about an hour and 10 minutes or so. I have also done as you said and after it dropped to 97% charged it back up and pulled it off immediately..same wakelock and similar time. Also this wakelock was not there with 6.0.0. So Google changed something with 6.0.1 that brought this to life for me. Also interestingly, this wakelock was at about 4-6 hours with stock kernel. I changed to AK kernel and that is what made it drop to about an hour and doubled my standby time.
OK, I froze Light Manager with TB and this wakelock went away. This was the only new thing I added to 6.0.1 to get the battery fully charged light to not change until 100%. Stock changes it at 90% for some stupid reason. So if anyone is using an LED manager, try removing it for a day and see if that makes this wakelock go away.
so here is the source. Are you guys all using the stock charger that came with the device? Only reason I ask is because I didn't start seeing this until I started using a samsung charger with a micro to c adapter.... I think
Reported at 93% it's my highest wakelock. Stock charger and no LED manager installed. Other causes or fixes?
I too have this at the top of my wakelocks. Did anyone else find a solution? I don't have any led managers

Exact same problem here... any luck guys?
HTC 10 (Stock Australian Variant - 7.0)
I contacted Lenovo support on email. As usual they told me to do FACTORY RESET. I did factory reset but eventually after couple of days issue started again.
there is some issue with SMB1351 chip on motherboard of Lenovo P2. but they are not able to figure it out. In battery stat, there is no issue with any of the apps which i installed on my phone.
any help on this is greatly appreciated.....
Hi, I have exynos version of my s8. It's about 1,5 years old. After update do Pie, I have a lot troubles with battery.
At first, if the battery drops to 8-6% it will die in the next 1-2 minutes. I try to do charging from 0 to 100% to recalibrate battery indicator but this don't helps.
Now I see something new, If I will plug the charger for example at 8% battery status it will drop to 1% (8-7-6-5 etc) and then it starts to rise... I have never seen something like that on my previous phones. All the problems with battery started after updating to Pie... Do anyone else have similar problems? Are there any solutions to this issue?
