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
After logging the temperature for a few days I've noticed a direct correlation between phone temperature and battery life. The phone drains 1% every 3-4 minutes when its at or above 35. when its around 27° or lower it only drains about 5% per hour... I'm having an issue however. Today my phone was extremely hot. Right under 40° all day... with the screen off 90% of the time. Tonight I'm doing a test I've removed the back cover and its nowhere close to as hot as it was.before. I'm starting to think the battery cover is too close to the battery and internals thus causing overheating issues. I love this phone but I may try to swap it out for another while I still can. Has anyone else noticed similar issues? I'm underclocked at 800mhz screen brightness 10%. Does at&t charge a restocking fee if I return it?

well there must be a big current draw for it too get hot. android has a bug that shows up occasionally where the radio consumes large amounts of power. also 2.3.3 has a similar bug where the system wont sleep, this should only effect gingerbread but it may just be more frequent in gingerbread.
check battery usage in settings>about phone. if anything other than the display is over 50% there is a problem. if it is android system then shut it down and pull the battery for a few minutes, start it back up. if it is the cell radio then put it in airplane mode for a minute and take it out of airplane mode.
removing the cover may help it stay cool but there isnt enough heat there to cause battery drain, instead the cause of the battery drain must also be the source of the heat.
was almost thinking bout buying this phone as its very hot in africa this could burn my hands
I am on my second Infuse.
My first one had battery charging issues, and compare to the current one it was also a battery hog. I did not put two and two together until the current one i have, but the first one would get hot around the camera area with just streaming slacker while browsing the web.
I exchanged it like 4 days after i got it due to it taking 6.5 hours to charge from 5% to 100%.
I just had the same issue... it was down to 10% so I put it on the charger... 3 hours later I looked back and its barley on 40%. It took 7 hours to fully charge last night. Something isn't right. Now my screen is completely set to off and I'm underclockong and its gone from 24° to 39° in 5 minutes.

please check the battery usage in about phone. if anything other than the screen is around 50% there is a problem, the solution may be as easy as starting airplane modeand turning it off
Hello.
I have Samsung Galaxy Note I GT-N7000 I have problem... serious. I was watching Netflix and recharging my phone. Then i got warning of low battery and it turned off after 5 minutes and it was "charging" Well then i leaved and next day, i but it to charge. Battery image appeared to screen and was there about 10 seconds. After 2 hours of waiting i tried to start the phone but it didn't. Now i tested the voltage of the battery and how ever (-0.00 V) No life in whole battery Then my dad told me to take out the battery from phone and leave it to table for an hour and check does it work.
Does anyone else have/had problem where Battery has died?
Can it be fix'd?
I tried cleaning Micro-USB port!
Thanks.

How long have you had the battery? They don't have a very long lifespan and die quite dramatically. If you put it on a flat surface can you see its bloated and spins easily? If so it's definitely gone and needs replacing.

Hey guys,
You can see the problem in the Screenshot. At one point the phone stops charging fast and goes on charging very slow. It looks like the phone thinks the battery is full and minimizes the charging power. It is a 1500mah battery, bought a few days ago. I also calibrated the battery at 100% in the 4ext recovery. CM 10.2 from 08.08.

Provably not a problem at all. My guess would be that the battery or charging circuits were getting too hot so it dropped the charging current - fairly normal behavior.
The phone is staying completely cool. I think the calibration is wrong. It is supposed to charge slower at 90% Not something like 50

I suspect a cheap battery... What brand is it?
Its a german brand MTec, oder via ebay.
I've noticed my battery does the exact same thing. Charges quickly to around 50% and then very slow for the remaining 50%. I'm using the original HTC battery that came with my Desire S so I just presumed that it was either the due to the battery aging or perhaps due to the CM 10.1 I'm running. Can't say I noticed this charging behaviour before I used CM 10.1 but I didn't immediately notice it after flashing either.
My phone takes around 8 hours to do a full charge. I've noticed that I can get it to charge to 100% more quickly if I let it charge to near 50%, unplug it and leave it for 5/10 mins, then plug it in again. It's starts off with a fast charge again. It slows after a while but overall it's a quicker way to get to 100%. It's probably not the best thing for your battery to do that regularly so I don't do it unless I need it to charge quickly.
Basically my nexus 5 switches itself off at random battery percentages and then when u switch it back on it will be dead or on a low percentage, this doesn't always happen but you can imagine how frustrating it must be.
Just wondering if anyone has had an issue with this and if I just need a replacement battery.
I have included a screenshot of the battery graph
Thanks
Faulty battery I guess...
replace your battery
