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
Have to charge almost twice a day... I believe it happened after latest 1.45.531.1 update....
Disabled all animation, got auto adjust for display, disabled all what I could.. Still gives me 12 -16 hours on standby only....NOT even using the phone!!!!
Does anyone have something like that??? Or there is some remedy I skipped?
Sorry if I repeat someone's question.
Running full stock, HTC battery.
Thanks in advance!!
Tester.
PS. Recently exchanged the phone.... First one R.I.P......died completely, didn't even charge.
Is there a chance they swapped a refurbished one on me??? How to find out???
can you provide a screenshot of the battery usage graph? also, have you tried getting an aftermarket, bigger battery such as the anker?
I was the same way as you. I checked my battery graph, and standby was using something like 80% of the battery with almost everything turned off. By the time I got home from work I would need to charge it immediately. I bought one of the Anker batteries on Amazon for $15 bucks or so, and I'm now getting about 2 days for a charge. I don't know what it was with my battery, because it sounds like my experience wasn't typical, but I didn't really feel like going through HTC when I could just pay the $15.
I'm with ya...
This phone was running PERFECT prior to the HTC update. Now I'm having a plethora amount of problems, including the battery. For example, prior to the update I would get 13-16 hours on HEAVY usage... Moderate usage? Try a day or day in a half. Now take today for example, I unplugged my phone a little before 7am and I had 20 something percent 4 hours later.
I'm telling you, that HTC update really messed this phone up IMO.
Thanks, guys!!
Will try to get Anker battery, I believe it's 1900 mAh.
But again something running on the background with that update. We'll see.
I'll try to get the graph, maybe someone'll get some sense of it...
Much appreciated,
Tester.
here are the battery stats...
Display..........74%
Cell standby...13%
Phone idle......11%
Voice calls......2%
THAT'S IT!!! Nothing else is running...... SUX...
Still gives 12 - 16 hours of life on almost idle......
I hate to say it,but if you're battery's dying a lot faster after an update,a bigger battery won't help much.
I'd be getting in touch with HTC and ask them what the heck is going on.
Really annoyed with the battery performance. I checked and only display is using 90% of battery. Tried everything to reduce it but no change.

I've had the same issue since the update. My battery drains at a ridiculous rate. I've become really frustrated with the phone since. I rooted it and flashed a custom ROM in hopes of solving the problem but it's the same deal.
I've confirmed it's not the battery either since I've got another one I've tried and only get the same results. Even with Juice Defender running I get nowhere as great a battery life as I did before the update
I'm doing decent 8hrs 20,mins on batt. With 40% left mostly text and internet browsing

Try clicking the graph at the top of the screen it will give you another screen that shows awake/screen time etc. Is your phone going to sleep when you screen turns off?
I was having the same problem and realized that some app was keeping my phone awake even though the screen was off. I uninstalled 80% of the crap I had installed and now my phone sleeps like it should and battery lasts amazingly long time.

How can you tell if your phone is going to sleep when you lock the screen? What is a good method for this? And if I find it its not sleeping when it should, is there a way to find the culprit easily?

Click on the graph in battery stats, it should show awake time and screen on. If your awake time is constant when the screen on time isn't, then chances are you've got an bad app somewhere preventing the phone from sleeping
my battery life was plain **** on 2.3.3., device was running hot all the time (=waste of energy), charging took ridiculous 4h+! When I took it off at the charger around 23:00 the battery was dead at 14:00 the next day with most time being idle!
Since my update to 2.3.4 things got so much better. charging takes around 2h and battery finally lasted a whole day and had 40% juice left in the evening.
Since I got my 2 Ankers+charger for 20$, battery life is crazy now. Been on one charge for 2d2h and still had 16% left. Pushmail on, wifi on (cellular data only when not at home), brigthness at 100%, taking video, pictues and some navigation, messaging and phonecalls. Oh yeah and a few minutes of flashlight use
I would say between slight and medium use.
If 2.3.4 worsened your batterylife, contact HTC or your vendor.
I now replaced the battery at 16% with the other Anker because I still need to do my 5 charge cycles on that one to calibrate it.
Here's an example of the graph. At the bottom you can see awake and screen on time. I pulled phone of charger last night, did some browsing, then ran for an hour with music playing in the background (you can see the small green bar on awake even when screen is off). After I surfed a little and left it off the charger when I went to bed. The phone is properly sleeping when the screen is off and almost 16 hours and still have 62%.
Before I uninstalled the apps, the awake time was solid green across the screen.
Anker battery worked wonders on my device. Before I would have to throw it on the charger after lunch as I like to go for a beer after work and the stock battery would never make it that far... Now when I get home from the bar I still have ~30% battery. Anker battery FTW!
flash a custom rom and u will go gaga over ur battery life. definitely works for me. on standby overnight drain 0-1%.
I found out that if you don't have strong signal at your location your battery drains pretty fast that's why I always connect my phone to WiFi at my apartment where my phone looses signal sometimes. now I lose just 1-2% of power during a night.
Sorry to hear about your battery troubles. A couple days ago I rooted and switched to "Android Revolution HD 3.0.4" and my battery life seems pretty solid. I wasn't having battery life issues prior to this though.
I'm currently in the process of calibrating the battery:
- drain it mostly
- turn off
- plug it in overnight while still off
- in the morning unplug, wait 15 minutes, replug for a few hours; do this ONLY ONCE or you may damage the battery
- power on, immediately go to recovery, advanced, reset battery stats
- start normally
- drain battery until it shuts down; a continuous stress test or stability test app is probably ideal
- once it shuts off, turn it on again to double-check that it's dead; it should only come on for a second or two
- while off, plug in and allow to fully charge; no fooling around with plugging/unplugging, just normal
- calibration complete!
I think you can follow a similar procedure (minus clearing battery stats) to refresh the battery calibration even without rooting/custom recovery. I've read the effectiveness is similar. The phone just needs to be retaught what "full" and "empty" mean, all in one charge cycle. If you calibrate it wrong you could have issues with it shutting off while still reading ~15% battery life.
Anyway, as I said, I'm in the process of doing this. Currently I'm in the "drain it" phase... with my screen at maximum brightness (remaining on), overclocked to 1.5 ghz, I've been running "StabilityTest" (from market) for one hour and fifteen minutes. It stresses both cores as well as the RAM. At this time, my battery is at around 30-40% or so, and it's getting really hot! The phone's temperature is reading as 54.8 degrees!
Also, yesterday I used the GPS for about 4 hours before it died, this was prior to any calibration attempt. I think this is within typical battery life considering that the screen stays on.
TL;DR: Maybe you just need to try a custom rom or recalibrate your battery. Miscalibrated battery can be caused by flashing/updating a rom, I imagine even when it's an OTA. Sense is crippling your phone anyway, you might as well give it a try IMHO.
get yourself an anker battery..I havent charged my phone since the day before and now i have 20% left! heavy usage

Hey guys I just got my Anker Battery 2 days ago and it says to let it charge and discharge about 5 times before getting better results. So far so good and its getting better. I'm on my 2nd charge but just so im clear on something here...
By charge to discharge does it mean to charge to 100% (turning the phone off) then discharge to 0% ( phone shuts off) and charge to 100% again 5 times? Been doing that and im not charging in between so it's a mess when it runs out while I'm not home (happened today!)
Also: any suggestions or opinions on the product so far?
Ps:was in supposed to clear the battery stats or something?

I only do it 3 times.
As soon as I get the battery I turn it on & run it into the ground. After it's shut off from a dead battery I plug it in & let it charge with the device still off. When the charging light turns green I turn the phone on & run it into the ground again. Rinse & repeat for 3 cycles.
I love my Anker battery. I get way better battery life with it versus stock & it doesn't overheat like it the stock one does. I use one, my buddy with another Sensation does as well, & my mom with her MyTouch 4G has one too. All are outstanding!
Sounds good...i should try it too

just ordered my anker yesterday - i think the 5 times advise is the same like deleting the battery stats - more a software then hardware related thing
Sounds like your training your phone to establish effective range. Personally I would run it into the ground five times, but some people say It's okay to charge when It's under 10%. Better safe than sorry is what i think. U only have two more cycles to go, suck it up.

I have had mine for a few weeks now and it is getting me at least an extra 20% with heavy usage...
Even the new Sensation XE only gets a 1750mAh battery I have read today...still under powered imo
The XE proves that the base Sensation we all have is definately underclocked and that running at 1.5GHz is quite safe...
My battery has been acting funny lately. Some nights I go to bed with the battery at 100% and when I wake up it's still at 100%. Other nights it loses 10-15% (in about 9 hours). I don't have anything running in the background that I'm aware of that would cause such a discrepancy. A couple nights ago the battery lost 10-12% overnight with the phone turned off! Still the phone was apparently awake all night. How is that possible?
I'm too lazy right now to post a screenshot since xda only accepts urls.
The same here after flashing a new custom rom.
After turning on the phone and making this screenshot percentage immediately went down for 10 to 15 %.
You can check things like that pretty good with apps like Battery Monitor Widget.
Did both of you try to recalibrate the battery?

Why would you only go down to 10? Might as well drain the battery completely. It's not going to damage anything unless you let it sit around dead for weeks, possibly even months.
It's never good to completely drain a lion battery

Actually, for a proper cell calibration, it is best to drain the battery completely. Many agree and I have never heard a dev say that draining it dead hurts the battery. It is essential for each cell to be empty in order to properly and fully charge a li-ion battery (without this, % figures will be non-calibrated over time). Just like it is of good practice to let the device charge and extra hour or so once the indicator light turns green (to ensure 100% after trickle mode).
Rule 1: Battery calibration does absolutely nothing. Deleting battery stats will never, ever do a single thing to help your phone's battery calibration.
Rule 2: Standby drain is almost always because of partial wakelock or kernel wakelock. Install Betterbatterystats to figure out what the issue is.
Rule 3: If your phone is in a good reception area and still experiences heavy standby drain, charge the phone until it reaches max voltage (4.2 or 4.3), then use it until it shuts off, then go to hboot until it shuts off, then charge to full again, preferably with the phone off. Wait about an hour after you first see the green light to turn it on.
After that, enjoy. If you still have issues, I would suggest backing up everything and attempting an ruu flash with the battery at 100%.
I failed to mention it, but I haven't rooted or installed a custom rom.
I'll try better battery stats to see what I can find out with that.
Hi! So I've been using this rom http://forum.xda-developers.com/showthread.php?t=1782009 for about 3 weeks now and I'm very happy with it but I've noticed my battery has been really really bad! Here's a screen shot and this was on a full charge :\
I replied on the thread with the screen shot but no one answered.
If anyone can help I'd really appreciate it
You need to check in better battery stats and see if your getting a wake lock. Read on google or xda how certain wakelocks can be bad. You can isolate the app causing the wake lock by using better battery stats and then fix the situation. Also could be the rom but likely it's a wakelock. Once you fix your issue, it will be much better. You can get better battery stats at the market or here on xda. Best wishes.

I'm having the same problem with the same ROM, I just installed a few hours ago.
18.18: 99%, stopped charging.
18.26: 89% battery left.
18.31: 84% battery left.
18.46: 72% battery left.
18.49: 70% battery left.
Until now I have used stock 4.0.3, and never experienced anything like this. I did barely touch my phone during these 30 minutes. It still has S-ON, could this be why?

No, S-ON/S-OFF has nothing to do with battery life. In your case though, since you said you just installed the ROM a few hours ago, you need to do about 3 full charge cycles before you start worrying about your battery life.
Drain the battery right down (not completely dead though, 10% is enough), charge to 100% and repeat a few times. Then if you are still getting bad battery life you can start looking at what is actually draining the battery.
