I got my refurb LG Optimus from T-mobile a little over two weeks ago. I set it up with Groove IP and have wifi on almost all day with the phone in airplane mode. Running stock 2.2 and stock kernel, haven't rooted or anything. Generally I had it unplugged for about 14 hours a day and would charge it nightly. Battery life would get down in the 20-30% range on occasion and it was generally looking like I would have gotten about 20 hours total if I would have taken it down to 0%.
Without remembering making any major changes (updated a couple apps maybe) I am currently at 2 days 4 hours since last charge and battery is at 60%. This is the first time it's going this long ... basically two nights ago I was about to plug it in when I noticed the battery level was still really high so I didn't bother. Still high last night so I again didn't plug it in.
Any ideas what would cause this to happen? Looking at the battery use, it is mostly the same as before (50% wifi, 19% phone idle, 15% cell standby, 10% android system, a little to display and some other stuff). Was the battery level indication just wrong the first couple weeks? i.e. when it said 30% left it really might have been at like 80%?
Not complaining at all of course and I hope I keep getting this battery life.
Here's a situation two ways of charging the phone 2 results.
1.Battery gets low TURN OFF the phone and charge it
2 battery gets low charge it while ON..
Two amazing results
1.charging the phone while off still yielded a full charge of 4200mah
2charging the phone while on yielded the same 4200.
Nothing amazing right? For the past 6 days I've tested this from a stock cm7 ZERO 3rd party modifications same activities for the last 6 days. 6 hours standby and 1:30 minutes of usage in browsing 4g only never wifi for usage. Now results
charging while off -20% really really dissapointing...
Charging while on - 50% BIG BIG diffrence. I've never touched any settings I just accidentally noticed that I left my phone on through a charge overnight and amazingly best battery life I've ever had on the atrix.
I did a search and found similar threads, but it seems that my problem is slightly different.
I have been using different CM9 Roms over the past few months and they have all been pretty stable, and the battery life has been pretty good.
However, I was on a trip last weekend and all of a sudden, my phones battery went from 100% to 40% in a matter of hours with the phone screen completely off.
I tried flashing other ICS ROMs, installing the blue sleep fix to no avail (wiping in between each, even doing a fastboot wipe as well). Then I restored a nandroid I had of a CNA ROM where I knew I wasn't having any battery life problems, but the problem still persisted.
I installed better battery stats to see if I could get an idea of what could be wrong. For example, this morning, my phone was charged to 100%. I took it off the charger, and it literally sat on my end table for 2 hours. I didn't touch it. I then looked at it, and it was down to 80%. I went into better battery stats, and it said under the partial wakelocks that the longest wakelock was only a few seconds. I then looked at the processes, and it said that deep sleep was the dominant process at 1 hour and 45 minutes.
Obviously if the phone is in deep sleep it shouldn't be dying that quickly (I would assume). Is there anything that anyone knows might be wrong with my phone that it is killing the battery across all these different ROMs?
My only other option is to completely wipe the phone and sd-cards and install nottachtrix, since I was getting 2 - 3 days of battery life on that ROM.

Have you tried the app CPU spy on the cm9 ROM to see what's eating at the battery CPU wise and to see if your getting deep sleep?

has anyone else suffered from this this is the 3rd time this has happend to me in 2 weeks i leave my phone charging overnight then take it off when i go to work so its at 100% charged then the battery has been draining really quickly this happend to me on tuesday and again today on tuesday it was at 20% at 11:30 am i take it off charge at 8:00 am and today the battery is already below 50% and its only been 2 hours since i took it off charge keep in mind i hardly use my phone at work and the days i do use it more than usual i still go honme with a battery level of around 50% when im off work wondering what can be causing this or do i have a faulty battery??
You got something killing your battery way too fast. Take a look at what you have downloaded/installed. Try wiping it clean and install everything back, one at a time to find the problem. I'm using Freeza's ROM and kernel, getting a full day of moderate usage and usually ending up around 50-60% by bedtime.
You in a bad coverage area?
My phone battery life has been very unusual these past few months. It charges too quickly on 400:700 mA currency. The phone just gains +10% in under a minute. And the phone shuts down too quickly too. Can't get through an average day anymore on my usual custom roms. It's not a rom particular issue since I've tried multiple including flashing miui and still getting very bad battery life. Phone shuts down at 20:30% and the phone doesn't even last 3 hours.
What should I do?
Seems like your battery is done for. Exchanging it with a new one would probably be your best bet.
