I just upgrade to cm 9.1 from CM 7 and everything works great except that my battery went from lasting 2 days to lasting less then 3 hours. I have been searching the forums and have lost 40% battery in 30 minutes of doing so. I know my phone is having a deep sleep problem but that. Doesn't explain the massive drain while on. I've tried wiping stats a few times tried different kernels I just don't know what else to do.

No matter what you do ICS will always drain your battery fast it is the very nature of ICS. ICS will never touch GB's battery life though.

Recently my battery life has dropped extremely low. I have been running setcpu to underclock when not in use to preserve battery life and it was working very well draining 1% on standby every 2 hours approx. A couple days ago I had it on standby and somehow in the morning the battery was completely dead after I had fully charged it the night before. It is such a drastic drop and I didn't even change anything that I think it's the actual battery itself. I can watch the %'s drop just watching my phone now. Has anyone else had a problem with this? It seems that the battery can't hold a charge anymore.
Looking at my phone right now, I had it off the charger for about 10 minutes after it fully charged and it's already down to 90%.
The first question that comes to mind is have you made any changes lately? Installed new software? upgraded something? If your phone was getting okay battery life last week and now it's not, it's time to start pin pointing what, if anything, has changed. Keep it mind it is possible for a battery to die...
Someone on this forum told me to erase the battery stats. I was told to go into the recovery. I use clockwork. There is an option to reset battery stats. This worked for me but do some research on this site. I am not an expert but was told to do this by someone who is

Anyone else seeing much better battery life after the 2.2 update?
Mine seems a world better
Yeh mine lasts almost 3 times longer
I'm still testing mine before commenting about this. When i give my findings i'll also put a summary of how i am using the phone, sync frequency, useage etc.
I'll let you know later tonight but so far seems about the same for me.
I think so as well, but it could be a placebo effect from the awesomeness of 2.2.
So far it seems worse. More to follow as I track this for a bit lomger, but my phone has been on for 12 hours and the battery is down to 45% with 40% of the usage attributed to Cell Standby and 37% of usage attributed to Phone Idle. With Eclaire, I would still have had 70% - 75% life left on the battery with that much standby and idle time.

mine seems to as well
just left on with a few background apps syncing I could see the battery drain but about 20-30% in 4-5 hours. Today it's still in the 90% range
How long does it take your battery to be fully loaded?
My Desire told me that the battery is at 9 % and it took maybe about 3 hours to reach 100 %.
Loading it while it was in Stand-by.
much better for me. no doubt about it.
Yep 100% to 86% in nine hours, with Eclair and this use it would probably be around 60-65%
I can't wait to get the upgrade
Hi guys I know battery issues are covered a lot but this is slightly different.
The past couple days my battery has drained a lot. Within 6 hours usually its a minimum 7 hours until it reaches 20%.
But since yesterday Android System has been partial wake lock, according to battery use it was 50%. It was only till I rebooted earlier this afternoon that it was cleared but saying that the drain after a full charge ive been on battery for 3 and half hours im already on 53%. Should I use battery calibration app to remove battery stats? Im not sure if I should as once I reach 90% the battery stats reset itself.
Im on stock rom rooted latest firmware.
Thanks in advance

Hi I have: HTC Wildfire with CyanogenMod 7.2.0-RC1
In about the past 2 days my battery life has dropped considerably with the phone not lasting more then 12 hours, as opposed to the previous life of 2-3 days.
I charged it too 100% last night and this morning when I checked it it was at 20%
I have not installed any new apps, my screen usually runs on low brightness and the data connection only running on 2g/Edge and I have changed no settings lately.
I tried a battery stats wipe, no change.
I remember having that problem just after I flashed a new recovery.
It was about 80% before I sleep And when I wake up I find it 55%
I installed Sympfinity kernel and it really improved battery life.
now only 10% (sometimes less) are lost through the night.
Try Sympfinity kernel.

I Flashed CM7.2 RC2 it seems to have fixed the problem.

I advise you to install battery calibration from play store, sometimes after flashing a new rom, battery may be miss-read
tip
the battery life is also affected depending on the time you have automatic update on your phone because if you have updated very often it spends considerably battery not in use so the phone .. hechale a look at this and help us a lot of your battery greetings
Welll i used to have a similar problem on my wildfire,so i downloaded power max and used it on standard mode and used Go power master with autoswtching and other stuff...just before exchanging it for a Nexus, i had the battery to last around 40 hours with 5 hours of browsing, 3 hours of listening to music and 2 hours of gaming with heavy use of whatsapp and texting and 30-40 minutes of calling...previously my battery use to last only 10 hours...hope this will help you...you can also go up to ebay and buy an extended battery for just Rs.960 which is 3000mah...cheaper than the original smaller battery....link to the extended battery http://www.ebay.in/itm/3000MAh-Exte...4-HTC-Wildfire-G8-/140533335447#ht_1453wt_907
So i'm running stock jellybean 4.1.1 OTA (yakju) however i've noticed battery life isn't great, charged phone overnight to 100% its been on standby for 7 hours and is already down to 68% screen time on is only 3 minutes, is this normal battery drain seems a bit excessive for standby.
depends on what you have running and syncing, etc.
you gave us no screenshots or anything to base anything off of.
I just charged up my phone from a 20 hour run, almost 4 hours screen time broswing with wifi mostly... stock JB 4.1.1
edit: oh i forgot i am using franco.Kernel
On my Nexus battery life isn't much better than on your Nexus, It is normal or then my Gnex battery is poor again..
I'm using "takju" JRCO03C with it's own radio + kernel so all is stock and battery life is enough good, for me on yakju builds the battery drains much much faster than on yakjuxw/takju builds..
My Galaxy Nexus's battery stays 14 hours with not using it and then battery is left something 12% or less, and when I use my Gnex then I can use it like 2 and half hours and then the battery has too less life to use it... (when Clock Alarm is on, and Hotmail + Facebook notification enabled...)
Google Now is said to use lots of power, have you tried disabling that?
I am also getting really bad battery life since JB. I have the extended 2000mah(?) battery so this might be the issue although I have not had any issue with ICS, I got about 26 hours with this battery on ICS. Now on JB I will go from 100% to 85% in 2 hours and all I did was text about 10 times, no phone calls. Today I woke up at 6am listened to Google music going to the beach, at the beach did not use the phone except to check the time.
Listened to Google Music on the way home, got home at 6:30pm battery was at 31%. I did not surf, made one phone call that lasted 30 seconds.
This has been about consistent since JB installation. Everything is stock except for the fact that I am rooted.
I am currently conditioning my battery, when done Im going to remove facebook and see what happens. Also can we "freeze" Google Now? This so I can test the batter.
Thanks for any suggestions and/or ideas.
I'll chime in to say I'm also getting slightly worse battery life on JB. I'm mostly observing idle battery drain during the work day. On ICS it was a steady 0.5%/hr, on JB it is over 1%/hr. So before I could get away with not charging it some nights and it'd only lose like 3% overnight, but now it's more like 7%. The phone is stationary during this time so I can't imagine Google Now is contributing much. I'm not rooted, completely stock.
What are some options available to investigate this? BetterBatteryStats or apps like that?
