so why exactly am i losing battery life on a reboot. its happening on every rom ive used so far.
I think its because your battery is not properly calibrated with the rom. Are you bump charging each new rom you put on and wiping the battery stats?
This happens to me. I am stock currently, but I have been through two phones and they both lost 5 - 10% on reboot.
It's normal for the phone, it takes a bit to "power" up the phone. Don't stress out that much over it. The battery % isn't 100% accurate anyway.
I'm losing ~10% on each reboot too. Its definitely not just from the reboot and I don't think its accurate. Yesterday, as an example, I was at 43%, rebooted and came up at 32%. Then my phone sat 32% forever, just flat lined in the battery stats for hours. It finally started reasonably dropping again hours and hours later as if the battery level had finally caught up with what was being reported.
Have you ever bump charged and battery wipe stats before?
Cuz mmy battery doesn't drop like that.
I don't think I lose a full 10%, but I definitely notice a significant, if not excessive battery drop when rebooting. It seems unlikely that the battery could have discharged that much, so it's probably a reporting issue. Not something that really bothers me, but just pointing out that I noticed it as well.

This was similar to what I experience. More evidence that it is a mostly harmless reporting error. The reporting "corrects" itself once the phone is booted. Interesting behavior, but harmless.
Download Battery Calibration from the Market.

Your battery gague isn't telling you the truth.
I don't even get a 100% charge. It sits at 97 for like 3 hours and then drops. Reboot usually only takes <5 for me though. I'm thinking ROM issue.

This really explains why you drop rapidly after unplugging your pone from charging to "100%". I believe the OP is referring to a step function-like decrease in battery level between reboots. That is what I'm referring to anyways. That link does have some interesting info though.
I've been having the same issue. Reboot sometimes drops the battery by 5%, and the battery gauge seems to get stuck after that. I've also noticed that sometimes if I reboot while it's charging, the % will jump something ridiculous like 20%. Just now, it was at 45% while charging, I rebooted, and now it's at 57%.
This has been happening on both BAMF and CM7, though I've always been using Imoseyon's kernels.
Same problem here. Bump charge and battery stat wipe is the fix but it's definitely a pain. Especially, since I am flashing a new rom everyday.
to bump charge does my phone have to be off or when it reaches 100 unplug and plug a few times? will that do. i hate having to shut the phone off especially for a number of hours.
Bump charge> charge the phone on till light turns green. > turn phone off> charge phone until light turns green> unplug and reconnect several times> boot into recovery> wipe battery stats. > done. Use the phone all day and let it die on that charge. Then charge over night turned on. And you are now calibrated.

because rebooting entails the re-starting of operating system, services, background apps, internet connectivity, and initial data sync. it's just the nature of restarting an operating system.

I think the question was meant to be something like, "why do I lose 5-10% of my battery after a reboot?" Of course rebooting using a little power, but that's not the issue here.

Because the battery gauge isn't reading it right. Solution. Bump charge and battery wipe stats.
I am running IC 3.3.9 on my Sensation.
Today in evening i noticed my phone was getting laggy and stuttering alot so i thought I shud reboot it. it was 32% battery left. after reboot it was 8%.. how did that drastic change occur after a single reboot?
Then i kept it on charge as it was falling rapidly and after 2 mins i got a message that your Phone is consuming more power than what is supplied... its not exact quote but something like that.
I kept it on charge for 10 mins turning everything off... the phone was laggy again and battery showed 10%, so i rebooted again while it was plugged to charger..When it reboots, the battery indicator showed 62%... how could it change from 10% to 62% in one reboot???
When i dont reboots it falls down at constant rate except at 100% it stays for a longer time and then suddenly falls to 80%..
Damn, can someone fix this indicator issue or tell me a solution? What is causing this problem?
I deleted battery stats once i flashed it about 2 days back and i thought it would return to normal after some cycles but tis getting worst
EDIT: Just to add: I am on Stock Kernel
1( How are you running IC? EDIT: Oh stupid me pff
2( it might be a bug, nothing serious. What you can do to make sure it is a bug, is to just make one of those magically battery drain happen again, and let it drain.
He is running Insert Coin not icecream sandwitch... I have similar problem ...
Recently I've updated my Note through OTA to 4.1.2.
I've spot that after update the Note is just draining the battery.
I could read about 10 hours on it before, and now it is only about 6 !!!!!
I even do not mention gaming, which is draining the battery in 2.5-3h from 100% to about 5%. I could play approx. 5-6 hours before.
It's ridicules.
Did any of you spot the same thing?
I haven't installed any additional apps after update that may "help" to discharge the battery.
The values above are based on Screen usage time in Battery menu.
Any suggestions?
After the update, I'm facing recharging issues. The tab is taking twice the time of what it used too to recharge to 100%.
i haven't spot any issues with charging.
.
Same here.Used to get 10 hours of screen on time,now i am lucky if i get 8 hours!

Some tips :
Kill all apps, switch to offline/airplane, and power saving mode when charging..
Still not working?
Try reboot your device once or twice if necessary..
And your device will charge normally
Work on my gnote...
I hope it will work for you too
Correct me if i'm wrong
Im using juice defender with good results, I lost a pretty noticeable amount of battery time after 4.1.2, too.
Maybe a problem with the battery stats?
Try to drain the battery empty and full charge afterwards.

It will damage the lithium battery when you drain it till empty
I think it is Wi-Fi that drains the battery !!!!
Usually I was leaving the tablet with wi-fi on all the time. After 4.1.2 update it takes approx 2% of battery per hour !!!!!!!!!! when you do not use the tablet but wi-fi is on, so after night in the drawer you had approx 10-15% drained.
When I turned the wi-fi off and left it overnight i haven't loose even a 1% during the night !!!!!
I have to try to work on it as usual but with wi-fi turned off, it will be difficult though as usually i play on-line or browsing the net
I think they f#^%*d something in 4.1.2 update with wi-fi energy consumption. hope they will repair it in next update.

I mean, just let the device turn off by itself, and after that, charge 100%.

Yeah, I had this problem after I updated too. It was also laggy. I did a factory erase and now it works better. I think it is still draining more than before, but not as bad as after I updated. I think a good rule of thumb is to wipe everything after an update and start all over. You could also try wiping and flashing the rom for a fresh install.
I suggest you to change your rom to germany stock 4.1.2...
It will solve your charging problem
Tested on my gnote
Hi, my phone battery keeps messing up. I have done a battery calibration but it still seems to mess up.
The main problem is that the battery runs out, 10 mins later I have like 3 percent battery, then that runs out so I start to charge it, it charges up to around 20 percent then it jumps to around 60 percent.
By the way I have terrible battery life too - maybe 1 to 2 hours of use before running out.
Edit - I didn't say this but I am on albinoman887's cm10.1 rom.

I'm facing a similar issue, and changing Kernels doesn't seem to help either.
Things have gotten slightly better now in today's build. If updating doesn't help then you should try staying in an older build, the last where the issue was not present.
I don't think its the ROM's issue. Even by itself, after reboot I gain a few % of battery but those deplete quickly.
And then while charging. I restart, from 20% to 60% is possible too. So its not recommended restarting while charging.
Full charge then calculate drain pattern.
I have similar problems. My phone also shuts down very often. When I turn it on again it shows strange readings like 0%, 11% etc. If I reboot my phone it might either stick with the percentage it showed before, not boot at all, or jump back to 80% or so. However, it never takes long before it shuts down again. Even happens sometimes when using my charger...
Chances of my phone shutting down instantly are nearly at a 100% when using the flash while taking a picture.
I don't know what to think in terms of whether or not this is a software or hardware issue as many other people have similar problems, all on different roms and kernels.
Currently I am on:
Firmware build: 3.33
Kernel: Sultan Kernel r21
Rom: JBMIUIv4.1 #3.3.1
about battery percentange when chraging it's a commonn htc issue
i have the same too
no one has found a solution for it yet
Do you all get bad battery life too? Because I don't seem to get a very long battery life.

No. The battery life on Albino's builds has been nothing short of fantastic for most. You might consider replacing your battery if it's the original stock one. It's bound to be wearing out by now.
I have just bought an anker battery so I will see how it fairs vs he original battery.

I believe its something that occasionally happens when u change a rom and kernel. I remember theres somewhere where u can reset battery stats....i think in clockwork...

In fact, kernel and ROM do affect battery life, search for what fits your cell phone the best.
I get amazing battery life on ViperS 1.6.3 and the latest Faux + Yank555's kernel besides TurboBoost MOD... These can make up a great combination

I dont think they affected the rom so much as to ruin the battery or drain it faster. Charge the battery and reset stats 90% i bet it works.

I have had this problem through numerous roms so i have put it down to the phone and not the software.
R: Strange battery stats.
It can happen at any point if u ever flashed a not-so-secure or old rom.
Once the battery percentages, for any reason, get corrupted, theyre gonna stick to being corrupted no matter how many flashes u try.
Really its not that difficult u just have to press a button (i believe, as i said, in clockwork but im not sure) and all that will happen is when phone reboots battery will get reanalyzed and resynced, nothing else gets modified. might save ur day.

You are describing 'battery calibration'. Its complete urban legend hogwash. It does absolutely nothing.
Wiping the battery stats has no effect whatsoever on battery performance. Those stats get wiped every time you charge the phone to 100%.
However, you can improve the battery reporting by charging to 100%, then draining all the way to 0%, then charging all the way back to 100% again without rebooting (other than after it shuts off at 0%). This is not calibration. Its just running the battery through a full charge and discharge cycle. This helps to stabilize how the draining is reported. It does nothing to actually make the battery last longer.

Then please explain how I can drain my battery to 0% if my phone shuts off every minute. As long as I keep the charger plugged in, my phone will function like it should. However, as soon as the charger gets disconnected, it's only a matter of minutes before the screen goes blank and my phone shuts itself off without notice. Then when I reboot, chances are that either 1) it won't even boot and shut itself down at the splash screen 2) it's gonna give me a strange battery reading and shut itself off again after 10 seconds of activity. So how am I supposed to drain my battery if I can't even get it to drain, because it constantly shuts itself off?

The stock battery that comes with the Sensation is known to have this problem. I experienced this problem quite often before I was rooted; a new 1900mAh battery remedied the issue. Here is proof that this isn't software related: after becoming extremely frustrated with the lags and random reboots of my recently ICS-updated Sensation, I decided to do a factory reset. The phone restarted normally with all data wiped and everything seemed like normal again. So I was just sitting there happily with my phone at 50% battery. I decided to open the browser to go and browse the web, and the phone was quite goo- BOOM! RANDOM REBOOT! After my phone finished rebooting, it was at 4% battery!
Moral of the story: HTC doesn't know how to make batteries. Buy a third party battery like Anker.

battery life varies from phone to phone, kernel to kernel and rom to rom. but your battery behavior sounds exceptional.
Like stated previously, wiping battery stats in recovery (Battery Calibaration does exactly the same on rooted phones) has never proved me to be efficient. Random shutdowns occur when the phone isn't recieving enough juice from the battery, the demand in voltage will exceed the CPU's capacity and the phone shuts down to prevent damage.
here's something you can try and it worked for me. I used to have random shutdowns and poor battery life aswell.
Wedge a piece of paper, like 0,5-1mm thick, between the upper right corner of your battery, and the battery housing. This way the battery will be presses firmly against the 4 contact pins. Also make sure the contacts are clean.
maybe it's just a battery issue. What does the battery info section say about the condition of the battery?
My anker battery arrived 2 to 3 days ago and it seems to have stopped all problems with the battery.
Thanks for all the suggestions though. I will refer back to this thread if any other problems arise.
i know there are a lot of other threads out there, but I haven't found one that talked about the problem deeper and has a fix. anyways, I'm experiencing a serious battery drain where I charge my phone up to 100, unplug it in the morning, go to school and leave it in my pocket for 2 hours, and it ends up being 70-80% and the screen on time isn't even on the battery stats because I've barely used my phone to have it show up. As im typing this on my phone, ive even lost 2%. Is anyone experiencing something similar and is there a fix for this? At 33% now, according to the battery usage, cell standby is at the top of the list with 10% and screen on time is 25 minutes . Thanks so much
Please post some screenshots of battery stats and someone may be able to help

My phone is the same way. Even with the latest update that made cell standby way better where it sits at 1-3% my phone drains like crazy. It's been off the charger for 3 hours and 1 hour of screen on time and it's at 57%. They need a bigger battery in the s7.
Check to see if you have a VPN app installed, Firefox, Candy Crush (or other King app), or a weather app. Many use mdnsd that eats power. King apps send data all the time. And there may be some adware that you have that is eating power. Hope this helps...

Battery Drain
I have had the same problem. With the earlier update I had the issue with (what I consider) excessive drain caused by cell phone standby. With the latest update cell phone standby has taken a back seat to Android System. Here is a screenshot from today. As you can see Android System has more than twice the percentage of anything else. I reset the phone a couple of days ago but that had absolutely no effect. Went to a local Verizon store to complain which naturally went nowhere.

I did a factory reset in recovery wiped cache twice and rebooted I have had much better battery. 20-30% higher when I leave work. I also kept WiFi calling turned off not sure if that was the drainer.
