Random battery percentage drop?

Im running calks 3.0 with gunslinger with the aggressive tweak. When I reboot my phone the battery will drop in huge amounts. For instance I was at 44 percent then the reboot. When it came back on I was at 7 percent life. Any ideas how to fix?

Interesting, you actually recover somewhat after the drop. Mine would be somewhere below 15% and continue to drop from there.

I have that issue as well. I ran battry calibration app from the market. it wipes the battery stats and lets the rom rebuild new ones. it helps. I don't have that issue as much unless im flashing a new kernel.

Battery Life Poor on Blazer 1.6

When I first installed this rom, my battery life was great. Now, I think something is wrong because the battery life has been running out faster than normal. For example, this is my battery just today:
I am using the freeza dual core fix and I just recalibrated my battery last night. Does anyone know what could be causing the poor battery life?
A rouge app. Or your settings.

I looked at better battery stats app and there are no rogue apps running. My settings are good too. I'm so confused.

I know it was. Everyone's is. Except mine :/
Sent from my SPH-L710 using xda app-developers app
try flash a different radio or try a different rom. you will see different battery result.
Mines is OK.... in 14 hrs I had left 45% left ..
Sent from my SPH-L710 using xda premium
I just flashed the new radio so I'll see if that helps. So far, I got 12 hours of battery with 3 hours screen time, which is still pretty bad

Charging times change

I noticed lady night that the charge time slowed down after a few hours. I'm using the mugen 6400mah battery and I've never seen this happen. I didn't use my phone during the 6 his it was on charge. Any ideas?

My battery started this all at once. HELP

Fully charged 12 minutes ago. Rebooted phone and battery went even lower. Why is it doing this? It started doing this and progressively got worse when I recently installed AOKP again but didn't do this before. Should I re-install? Would that help? I've had random bugs before from aokp. But not sure if this is part of it.

Could be something wrong with the battery itself I'd try and use a friends battery if you know anyone who has the same phone

Really doesn't make any sense at the moment. Charged it back up earlier and now it's fine. Really don't understand this.

It's a problem with your UI. It gets confused and the battery percentage goes off. Calibrating it has been proven a myth.

Terrible Battery Life :(

I think I got a dud because my battery life is sucking real bad. I had G2 for over a week and I have to say, the battery on G2 blows Note 3 out of the water which bums me out. I mean 7% in 35 minutes is simply unacceptable. Anyone else having similar problems? Should I take it back to the T-Mobile store and ask for a replacement? Any help will be appreciated. Thanks

So far my battery is really good.

I guess I'll replace it tomorrow. I am also not happy with the wifi signal strength. It's hardly one bar. I am getting convinced that I got a defective one.

Can anyone else post their stats so I can at least compare. Please!

Hey buddy I work for tmobile... we are told to let the battery die completely and then charge all the way up to 100 and then unplug.

My battery life seems good so far. I'm still on the pre charge. Got about 3 hours phone call 2 hours screen on. And 18% left. Haven't done my first charge yet.

usually when you get a new battery you're supposed to condition it. but anyways, I usually turn off wifi, gps, disable pen detection when in holster
Here is another picture showing 3% drop in battery juice with only 17 minutes of usage. This is freaking embarrassing

Let the plucking battery cycle a couple of times. I'm sorry but youse sound like a bunch of whinny brats. It takes time for the battery to reach peak performance.
Sent from my SM-N900T using XDA Premium 4 mobile app
Is that with 17 minutes of screen on time? If so, ur battery is fine. Ur on pave for over 7 hours of screen time.

3% in 17 minutes of screen time is not bad at all

Yeah these screenshots without on-screen time are useless.
Even 10 minutes of on screen time for 3% is pretty good - that's on track for 5.5 hours of on-screen time.
What u talking about batt is breast since I got my phone I got it 45% out of the box. And it's still running good so far
