I have the 2750 mah battery in my phone. Bamf 1.5 with the new radio. 4 hours off the charger and it is at 65 percent. Any idea? All syncing is off, screen at 40%, no Widgets other than fancy widget on. This is nuts. I can't figure out what's going on.

Have you wiped battery stats?
I have the same issue. One day my phone goes 20+ hrs on a charge, the next day it drains 40% in 3 hrs, with no significant change in usage. I've swapped kernels, wiped battery stats, kill nonessential apps & services, and I still can't find the culprit. But my extra battery is in en route, so I'm not too concerned
No. Haven't wiped battery stats yet. I heard bad things about wiping the stats on the TB.

I get the same thing every few days and it drives me crazy. You can instal a current widget and it'll show you what the draw is. Normall idle I'm at 38mA. But in these bouts of mystery drain it'll go up to 250-300mA for no reason. And this is with wifi/4G off too. But once I turn it on airplane mode the current goes back to normal until I take it off airplanel. So it's something to do with the regular cell radio...
Its ridiculous. Its stuff like this that kind of make me wish HTC held this back another few weeks.

yeah i have this issue also. today Google Voice had partial waked my phone to 50% battery. i don't get it.
I have seen the same thing, anyone also notice the battery cooking when the drain is going on. I usually reboot the phone thinking an app is hung just banging on the system, sometimes it works other times not so much.
+1 i'm seeing this as well. when its happening the phone gets really hot. i hope this gets figured out.

I had this problem on the BAMF 1.5 ROM + kernel combination. I recently switched to Imoseyon lean kernel (http://forum.xda-developers.com/showthread.php?t=1021404) and now the battery life is amazing. I've been off the charger since about 12:33am (CST) and it is now 12:28pm (CST) and I'm at 52% with average use.
On battery calibration. I strongly recommend doing this if when you restart your phone you lose drastic percentages. I was losing 11% with a restart indicating that it wasn't reporting accurate battery status. I used the battery calibration tool which is on the market. Now here is the kicker that i learned from Droid Incredible days, you have to fully charge the battery. That does not mean wait till your phone reports 100% that means turn off the device and charge until the notification led turns green and start up the phone and let it charge to the light goes green again then calibrate. Then disconnect and use til completely dead without plugging it in AT ALL!! This has worked for me.
Hope this helps everyone.
i really hope this thread doesnt die since this is a real problem apparently quite a few people have....
I didn't read all the post but after flashing a radio you have to wait a couple days yoga week before the battery can recalibrate.

Battery monitor is showing 1350mAh
Wondering if I have a bad battery or maybe that's how it's read? Shouldn't it read 1400 instead of 1350?
I have this problem too... Its because something is not letting the kernal throttle down. Check setcpu and you will see it stuck on the Max speed. The smartass gov is most suspect because it doesn't use profiles
It's just the way it is for now. For the last 2 days I've been getting horrible battery life. All of a sudden things changed today. Battery drain is between 30 & 38 every 60 seconds. 2 days straight of 250-300 drove me frigging crazy.
Thunderbolt - BAMF Remix 1.5
Yeah I have these random cases too. However a reboot fixes the issue. Besides faster than normal battery drain, you should notice higher battery temperature.
I believe it's an application issue, something that we can't tell yet.
Honestly I have high hopes for the TBolt down the road. When Evo first came out, we were experiencing similar problems too. Given time the devs were able to get them solved. This is why I prefer HTC and XDA.
I got great life today. Yesterday was terrible. I'm still getting the large drop in percentages on reboot, but battery life is draining slowly. Something I was wondering is if we lose 15 percent on a drop, does that mean the battery is actually 15 percent lower when I restart? So if my battery is at 60 percent in my task bar, is it actually 45 percent? And if that is the case, what happens when it drops down to 10 percent on my taskbar? In theory that would mean the battery had 0% life. Now the strange part of that is I'm still losing battery from 10% down to 0%, once it hits 0 it shuts off, however, if I restart the phone at 8 percent it won't reboot. So why will the phone stay running at 8% battery, but it will not boot back up after the restart. Its been a long day so sorry if I'm rambling or not making sense. But you know what I'm getting at.

Just the way it is, the thunderbolt technically has a 1350 mAh stock battery.
I saw a thread on another site that says, if you recalibrate your battery once a month it will help... Full charge... Unplug.. reboot...3 times only has helped mine.... Now I Only loose 2-3% of battery per hr...

oh ok. Thanks
So I bought my phone just after the first day of release. While battery life isn't bad its still pretty questionable. But for now my main issue is the battery level. When charging my phone, the battery level never reaches 100%, it usually sticks around 97%. When I go to check in settings, the battery reads fully charged but the percentage says differently. I just wanted to know if this is an issue that anyone else and if a battery calibration will help fix this.
This had been addressed many times if you charge a battery to 100%.... they explode after a while. 97 is normal and good don't think to much about it your phone is fully charged

It's a samsung/gingerbread feature , to prevent causing any damage to the batteries
Ok cool. While on topic of batteries, what kind d of usage are you guys getting out of yours? I've noticed that I need to turn off internet throughout the day without getting too low when away from a charger. I know around school I have bad signal and there's not much I can do for that, buried there any other advice?
Does anybody know why is the battery percentage so inconsistent?
I am just switched over to the sensation from the HD2. I have had the phone for about a week now. The first couple of nights I turned off my phone because it was around 20% battery life. The next morning when I turned on my phone the battery percentage was at 33%. I have done a couple of other times and the percentage goes up about 10% after a day of use. My wife's sensation does this also. I am using the stock battery, and I am not using any roms or mods. I am monitoring with battery monitor widget and current widget to make sure it is not the app.
Anyone else notice this?
battery monitor widget is not anything official from HTC.
I think that is your problem.
I have never seen my % go from 20% to 30% without charging it.
I thought about that also, but I will turn the phone off with the battery icon at the top yellow color, and then in the morning it will be green. So the widgets would have no effect on that. Like I said I have noticed this on both phones.
I have also had my batter meter go up after a reboot. Not sure why... The meter works good enough to give me an estimate or battery life. Good enough for me.

I am not worried about it, but is kind of interesting how power cycling shows the correct battery. It must be some kind of glitch in the OS or something.
yeah, it happens to me too! For example, after a full charge the % stays on 100% for about 8-9 hours and after that it starts to decrease. About the % growing, it happened to me two times... maybe it's about calibration...
Hello Xda community!
I'm not sure why, but recently my phone seems to be draining battery life quite quickly over night.
The really weird thing is this time, my phone was on the charger.
I put my phone on the charger before I went to bed last night, and the battery was at 65%.
When I got up the next morning, my phone was off for some reason, and I find that I only have 3% battery left.
Not sure if my battery is lying to me, but I have been running off the supposed "3%" battery life for a good 30 minutes now.
Either my battery is glitched or something else.
Any feedback is appreciated.

First, use zeppelinrox's Die Hard Battery Calibrator, and then after you finish the steps it gives you an option to view what is taking up battery life, uninstall any apps that cause wake locks. Also, you're going to want to freeze the default android gallery and get a 3rd party Gallery (I recommend quickpic.) As the 3D gallery can cause huge battery drain.
Many of My Friends are facing Problem With Battery as Rom shows wrong information about remaining Battery %... As a result your phone goes off and when you start your Phone again it starts to show different % battery that mean that your battery is not Calibrate.. I am making this guide so that every one on this world may enjoy their phone for long time...
Warning Do at your own RISK...! Dont do it again and again
Steps you need to Do -1 First thing you need to do is let your battery goes to 0%.. then again start your phone(Don't plug in charger) and repeat 1st step until your phone denies to turn on back..
-2 Then Charge your phone in Switched off mode to 100%
-3 Unplug your charger
-4 On phone
-5 Your phone is going to show % of battery lesser than 100%
-6 Charge your phone again in on mode to 100%
-7 Unplug your charger
-8 Restart your phone and repeat Steps from 4 to 8 again and again until on every restart u battery % shows about 97%to100%
-9Next step is to calibrate your battery Download free app from plat Store that is Battery Calibration
-10 Calibrate your Battery with the help of that app and make sure that your Battery % is 100
-11 After Calibration Use ur Battery Upto 0%
-12 Then Charge it again and Your battery will be Calibrated...
Enjoy..

DON'T ever do this! Discharging a Li-ion battery completely WILL decrease your battery life.
Next, the battery calibration app is nothing more but a hoax. It only deletes a file containing the battery stats which is ONLY used in the battery statistics screen in settings.
So please, DON'T!
It's true you get the same result from the battery calibrate app by wiping battery stats in recovery. Draining your battery does decrease battery life of li-ion batteries, same goes for your laptop. The theory to cycle your battery is a myth and actually wrecks your battery.

The 0% reported by the operating system is actually a bit higher than the voltage at which li-ion batteries will become damaged. Any modern phone should not allow you to discharge the battery to the point where it could cause damage.
Also there was an employee from Google IIRC that said wiping battery stats was useless because its only a file that keeps track of what apps used the battery and it wiped automatically when charged to 100%.

Well when there is fall in battery from 100% to zero in 10 min then u have to calibrate
I am not saying to calibtate it daily... as i said you have to go to zero once to complete one cycle..

I admit, when that happens, the battery circuit is probably in a dumb state and it _may_ be useful then. But doing this regularly is incredibly dangerous for the battery. Yes, some phones bias the battery reading but the post suggests to actually force it empty while turning it back on and on and on and that really kills it.
Still, using the app is just pure nonsense.

How about the 1st point of the first post? "Drain it to 0 then turn it on and on again until it doesnt turn on anymore"?
You could brick an hp touchpad by doing this.

Because 0% shown by the phone is.not actually 0% to gain that actual 0% we have to do that
Sent from my Karbonn A5 using xda app-developers app
You do realize why they make the reported 0% above the actual 0%. If you drain a lithium ion battery to actual 0% you'll permanently damage it. Also calibration is only useful if you want the OS to read the battery percentage more correctly. Lithium ion batteries themselves work perfectly fine with partial charge cycles.

That doesn't make any sense - you're stating in that post that turning on the phone damages the battery.
I will state this again: if you force your phone on and on again until it doesn't react, you may and on the long run probably will damage your battery. If your battery is not removable, this can also easily brick your device as seen with HP Touchpads.
If you feel that you must do something, simply drain the battery _once_ then charge it. This is the only thing that a sane electric engineer will ever advise.
Well that worked on my phone... i said that do at your own risk.... actually i am saying the same thing that drain your battery.. but if battery is not calibrate sometimes phone goes off even on 36% and if u charge at that point to hundread then that method will not work...

This is why you shouldn't/ need not calibrate your batteries.. It'll do you more harm than good.

are we in need to wipe battery status for once in the recovery
What about for me, me tab has been saying 1% the past 3 hours and I've been using it and trying to kill it so hard but whatever I do it won't die. I want to "truly" get it to 1% or even 0% so I can then charge it back up to 100% in hopes of calibrating the battery to show what my actual % is. Any help will be appreciated greatly.
