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
just had a thought, my g2x just started rebooting like crazy i.e it would get to the tmobile g2x android start up animation and after it finishes it would reboot. my battery was around 30%-35% at the time i was thinking maybe the battery cant maintain a decent voltage and it falls below the g2x voltage threshold while under load and boom instant reboot. this could also explain why some batteries heat up to hot as well, they dont have a high enough discharge rate to keep up with the demands of the phone.
this can be solved one of two ways get a larger capacity battery of the same discharge rate. or get a higher discharge rate battery of the same size. both of those will allow the phone to draw more power without overtaxing the battery and would keep the battery cooler as well.
I wouldn't be surprised if the battery drivers are the culprit for all our issues. The phone can't properly read the battery charge and so the battery overheats or the phone reboots itself in hopes of getting a better reading on the battery.
i noticed my phone starts to heat up when the battery level hits around 40%. i never really understood why.
Mine once rebooted when it was plugged in and 100% charged. I think when it's plugged in it draws power from charger not the battery. So your theory, if true, only explains some reboots, not all.

I may be mistaken, but if it was in fact 100% then it was probably drawing from the battery at that point. I believe that once they reach 100% they will cycle between battery usage and charging.
well i know from using lipo batterys in my r/c planes and cars that if you draw them below 3v it can damage the battey im not sure what Li-ion low voltage is but its near the same basicly once the battery hit around 3.6 volts at rest its empty and will not hold voltage at all.
and for the 100% full charge if the battery drivers is fubar it could be overcharging your battery and damaging it so it has less capacity so when it pulls a draw it cant keep up and reboots
I plug my phone in every day before going to bed, and unplug it in the morning. If G2x doesn't have overcharging protection my battery would have been damaged long ago.
Also, I used the phone several times when it was charged 100% and still plugged in, never saw battery percentage went to 99% then back to 100%. So I believe when 100% and plugged in, it won't cycle power source through battery and charger.

I will add a little information that may or may not have relevance. I have 4 batteries for my G2X (This is my solution to the short battery life). The LG battery, $25 AceSoft battery, and two $6 generic Chinese batteries. None of them including the dirt cheap ones cause my phone to reboot. Conclusions can be drawn from this information but I'm going to leave that up to someone else. If you want to test the battery hypothesis I suggest you buy some of those cheap batteries off of eBay and see if something changes. Would be a rather inexpensive experiment.
I agree, ever since I started using a 1900mah battery from ebay, the random reboots and freezing issues have disappeared completely, and I have been using the phone for almost a month now. Please try a different battery to get rid of random reboots and overheating issue. Hope it will help someone.

you know what, I bought 3 ebay batteries so I can swap them around if i don't have a charger. none of them did the black lock screen. weird.
I had random reboot issues using some of the custom roms + original battery.
Then I bought a charger + batteries off ebay, and reset to original rom, and havn't had a single reboot/freeze since.
i just had my second reboot in cyanogen with my battery at 32% after if rebooted it went back up to 45%. i was playing galaxy on fire 2 when it rebooted. and according to battery monitor it was pulling 931mA when it rebooted.
i think the battery discharge rate is substandard for this phone this is a high performance phone and you cant just stick a normal cell phone battery in and expect it to work. this is in part why some of the reboots are happening and why when people got new battery they problem went away for them.
You might be on to something. Everytime my phone restarts it is because it is overheating.

i wish we had more info on the batterys lg used like the discharge rate and everything. i bet they are .5c or 1c discharge that would be why they overcheat when under heavy use or charging
I got a replacement battery from T-Mobile this past Tuesday, and had two random reboots within an hour. However, since then, I haven't had one issue. 4 days and counting going strong... Knocking on wood. Phone is stock and rooted.
well i know cm fixed the battery should be in his next build also data speeds with gingerbread, should be build 54 not 53, something is wrong with 53 and root access so they are going to have it fixed im pretty sure in 54, here peep this via twitter.........
@CM_arcee RC
My dark magical powers have beaten the G2x's radio into submission. Starting tonight, p999 gets a battery meter and twice the data speed
3 hours ago via web
while that is awsome news i dont think the battery meter for the phone is really the problem it happens when the draw on the battery pulls it below 3v under load the batterys low voltage cutoff kicks in and shuts the phone off and then the spings back up and the phone restarts
I think it could be the chargers causing issues. My gf pulled my g2x charger out of the box and said it made her phone whacky and died after a few hours.
Her comment made me think about it.
I never had battery issues but I use my old nexus one and zune charger.
Food for thought

I had the infuse on the AC charger the other day, when I took it off, it had a message stating charging stopped because of battery temperature. Now battery will only charge to 35% no matter how long its plugged in. Also when phone is off the charger, phone is getting very warm to the touch and the phone is not being used. Do you think I need a new battery or is the charging circuit messed up? Thanks for any input!!!

If your able to plug it in and it shows it's charging then there is noting wrong with the circuitry. Your gonna need to replace the battery.
A new battery is much cheaper than a new phone.
Batteries heat up as the internal resistance increases over time. As Axiomkid suggests, get another battery. Do it soon. Old (or defective batteries) overheating run the risk of shorting, leaking, or exploding.
Better yet get two batteries and maintain them properly ie discharge to 10%, recharge to 100%, then swap out with another battery and let the recharged battery cool down.
Tried a new battery, it charged to 100%... but drained 50% in one hour. When I charged it again same problem is still happening. Thanks for all that helped.

You might need a new charger too. are you using the original Samsung charger? Try charging it from a PC too. The 50% drop in the charge could be a calibration issue too. It would improve that reading over the first few charges with the new battery.
yes i am using original charger, i have use a captivate phone charger as well. i think they are both the same. i'm thinking something is wrong with the phone because after charging and taking the phone off, the phone is getting really hot without being on the charger. like the phone is being used but it's not. could maybe the rom cause an issue like this? i'm thinking maybe trying to flash the phone with a stock rom and see how much the battery drains
Problem solved!!! Reflashed ROM and all is good

Glad to hear your problem is solved! Was that the root cause with your first battery as well?
Hi guys,
I got a mt4gs a week ago and it charged the battery at first but then after 3 days of use i connect it to the charger but still the battery is discharging, I got another battery but still its discharging while connected to an ac adapter. I am rooted and running miktouch 0.5. should I return the phone?
If it's doing the same thing while connected to your computer thru the USB, I have to admit it DOES sound like a mechanical issue.
That was happening to me awhile ago too. Mine was due to the USB charging pins being bent. I took the phone apart and was able to bend them back using a safety pin.
You also might want to try a different cable.
As a precaution, I bought a couple ankers and wall charger so I always have a spare.
Good luck.

got a new charger but still didnt work, going to return it.
Also have a weird battery problem on mt4gs.
Battery seems to drain while connected on AC, whether it's being used or not, but a restart shows it with more power. e.g. if I restart @ 52% when I restart it says 79%. if I restart again it may be 32% or another almost random number. sometimes 17%, 82%, 92%. I've tried all sorts of apps and wiping batter stats in cw.
Once I left it off and plugged in and the led turned from orange to green. But power on showed 92%. I tried two different batteries, it seems to be the same.
I worked properly before and I can't seem to remember when I realized it was doing this. Yesterday I also noticed, when I pull the battery for a while date and time resets. Dec, 1 1974 I think, Internal battery dead?
Anyone have suggestions?

I'm also having that problem with mine. Its in the cm9rc buglist, affecting users of some aftermarket batteries. I have the Hyperion 3500. Suspecting battery firmware issues...its always been a little strange. Reporting %100 for way too long, then declining normally for a while, then dropping from %30 to nothing pretty rapidly. Now on CM9 rc reporting is just random and inaccurate. Time to spend for an Anker. Ready to get rid of this heavy double-thick battery anyways. With consistent improvements in battery life I don't think I need it anymore.

Hmmm. Although I'm on virtuous Inquisition now. I was having these issues on the stock tmo from which prompted me to upgrade. Was on same virtuous Inquisition before that but went to stock because I just love the Genius button. :what:

I have bought two of these the first one swelled up until the cover wouldn't fit... now the second one the charge just goes away in idle... i am wondering if other people complaining about not being able to keep a charge is a battery issue and not a rom... i am constantly going back to my factory battery...it seems to hold a charge longer and keep its ability to hold a charge over years of use better than these after market bigger batteries... does anyone know of a good replacement that stays good over time?

How long have you had them? Totally sucks to hear that - I just bought mine a few weeks ago and love it thus far. I haven't had a problem with the original battery but I work 12 hour shifts in a cellular black hole. Even with data/wifi/GPS turned off, I normally leave dangling from a thread... I know that any lithium ion battery requires proper "care and maintenance" - have you been good about letting it discharge appropriately and not keeping it plugged in all the time?
My original battery lasted 10 months. It stopped holding a charge so I purchased the OEM 2600 battery and cover. Works like a champ - I get a full days use - and I only recharge it overnight. I am running stock/rooted/debloated, but I expect Tweaked to provide even better battery life. In my experience a swelling battery is due to excessive heat.
