Battery acting weird? - Nexus 4 Q&A, Help & Troubleshooting

I don't know if it's the battery or maybe the rom's battery display. I was at 33% when I plugged in my charger bam 100%.I rebooted and everything is fine. Should I worry about it?

No. It's a known bug. We all have it once in a while.

ICS battery use

I have been using my phone for about two hours straight now and it seems that android OS is using more battery than the screen. I thought the screen was the biggest battery drain.
Before you ask, this is the stats right from a fresh charge.

Won't charge properly..??

Has anybody else had charging issues with their Nexus7? Mine ran out of juice this morning and shut down on me so I plugged in in to the original charger and its been on charge to 9 hours uninterrupted... yet just picked it up for some browsing sitting in the garden and the battery is only at 35% charged??? Something not right there surely?
Any advice

Did you also use the original cable?
Yes, original everything....

Since posting this question, its been back on charge and as of now its up to 43%... not sure what's happening or if this was because it was completely dead I.e. wonder if the charger stops after a pre-set period??

There is a rather large thread on this issue. Something about which kind of cable and other issues. I have to use the OEM or it will not charge.

3hrs later and fully charged.... odd, perhaps a freak issue... so to confirm, used original charger and cable from the beginning... 9hrs to 35% then a further 3hrs with a disconnect to get to 100%
Thanks for assistant all,

Nexus 7 battery drain

Hi. It has been two weeks since I got the nexus 7. At first, the battery lasted for a long time. Now I'm realizing that it is draining much quicker than it is supposed to. What should I do?

Better battery stats to check the wake locks and cpu spy to see if your device is deep sleeping

My battery isn't very good either. Brightness on 0 percent and still only getting about 6.5 hours of screen time.

Battery suddenly drops to 0%

Hi,
Since about a week ago my nexus suddenly started to die at about 30-40%, it depends. I don't really care about the fact that my battery is empty, but the fact that it happens on 30% and I don't receive a notification at 14% is really annoying. Is there a fix for this?
I'm running Aicp with stock Aicp kernel.
EDIT: Since I stopped charging my battery percentage hasn't changed for about half an hour.
Edit 2: I rebooted and now it's 41%.. Really strange

It's getting worser now, it usually turns off when it's around 40% and around 50% I lose connection with mobile network and can't connect any more. I've tried different radio's but had no effect. I'd really like to know how to fix this. Or is the only solution to buy a new battery?

Take the back off the phone and see if your battery is bulging. This sounds like a battery issue. I had similar symptoms on my last phone. I took the battery out and spun it like a top.

Yeah I had it with my old galaxy Y too, my battery became so fat the battery cover didn't fit any more. But that happened slightly, this came out of nothing.

Haha, I was with friends and suddenly I noticed that I was able to spin my phone, and together with the fact that the battery was acting strange I thought it must have been swollen. And yesterday I saw a little lump.

Your battery stats will not be accurate until you drain more of your battery.
