Razr Maxx Battery Issues?

[avenged61973]

So I figured out my battery always jumps from around 40% to around 20%. It has always been dropping off right around this point over the last couple days.

Do you have a razr or a maxx?

Maxx

Ok I wanted to check because there are three threads I have been involved with and I get confused sometimes with which one I'm on. Lol..

This is the first time I've heard of someone having this problem with a maxx all of the others were with the regular razr.

Something I noticed on my phone when I had this problem is that I would let the phone go to 1 percent and it would last for 45 minutes to an hour before it would shut off. I know your not supposed to do that, but I was running out of options . it's like the 10 to 20 percent drop is getting made up when the meter is at 1 percent. If that makes any sense? I know the meter is off but I shut my phone off and charged it every time for 3 weeks and it didn't help. I'm completely out of ideas. I don't know if foxcat can jump in and help maybe give some ideas. But like I said I changed my razr battery to a maxx battery and it's been working perfectly.

I've been looking at new batteries, but I want to make sure it's my battery's fault before I spend $50 on a new one. Does anyone know how I can tell the health of my battery besides just looking at the time it lasts?

I don't think a new battery would help. The third replacement phone I received was brand new. It still had ics installed worked perfectly. When I updated to jelly bean the problem started again.

I'm going to see if I can get a free one out of Motorola, worth a shot.

Hey that is definitely worth a shot! Good luck!

I just found this part of gsam that shows kernel wake locks. Does this tell you anything?

I just compared mine to yours...I am 4 hours 43 minutes off charger and my kernel main wakelock is 1 hour 53 minutes. I don't know if this is good or bad. I really hope someone can jump in here and let us know.

I also noticed last night that my battery was at 15%, then it immediately jumped to 50% when I plugged it in. Maybe the battery isn't calibrated right?

I would try a couple of meter calibrations.

Tricia I think that is about normal. I don't have gram installed right now. I will install it and let you know what mine says tomorrow.

Or you could try this found on another thread...I believe this is FoxKat's method of calibrating the battery.


1) Charge phone (with Power Off) to full
2) Run phone down until it says 15%
3) Repeat step 1

I know my battery life is back to where it was on ICS. I can get a good two days with moderate use. But I sure do know how frustrating it is when your battery life goes down the toilet! Curious to see what yours comes up with.

 

[avenged61973]

Here's what my kernel wake time looks like. My phone has been running flawless. Love the maxx battery. This is with mild usage. I think yours is running pretty normalView attachment 62776
