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

i have flashed multiple Roms, and i will admit i have never went through with the FULL battery calibration, but one thing i have gotten after each rom/kernal install is, after charging full, and wiping battery stats, it seems with just little usage my gnex drops so fast, even with screen down, on wifi, just texting...i can literyly watch the battery drop.
is this normal since it has not been fully calibrated? if i let it completey die after wiping battery stats, will the battery drop significanly slower? i has tested this with both batterys, ext, and standard
THIS is my ONLY gripe and the ONLY reason i would return it..
Thanks..
If you're basing your battery off of the first few discharges after a rom install.. it is bound to be pretty bad. You can just go from full to empty and then charge to 100 to calibrate it.

That doesn't seem normal. I'm getting as good battery life as you can ask for with this giant screen. I recommend checking out the android revolution thread in the development section. Mike has posted a few links to threads that really detail how to maximize battery life. You may see your battery life increase after a week or so of usage. Good luck.

Hi!
I installed blackout ICS incredible in my DHD. Everything went well but I wanted to calibrate my battery.
So I downloaded Battery Calibration by NeMa from Google play. Before calibration my batterylife was about 12-24h depending on my use.
Now after the calibration my batterylife is about 5h!! And the same usage as I have always had, couple of calls, net surfing and maybe a little of Angry Birds and spotify.
Did I do something wrong or is my battery dead? My DHD is about 2 years old.
According to Google calibrating your battery (erasing your battery stats) doesn't actually do anything, so it shouldn't have made your battery life shorter. You could install BetterBatteryStats from a thread here on XDA to see if something else is eating your battery. Look at alarms and wakelocks.
Ok, thanks. I installed the BBS and I'll tell the alarms and wakelocks here if I don't find anything funny about them...
bananagranola is right.

calibrating your battery basically tells your OS how much batter it has or doesn't have. IF you flash a rom at less than 100% battery, then the max amount of battery your OS thinks it has might be different from how much your phone actually has. Sometimes this can affect battery life.
The other thing is, did you calibrate at 100%, then unplug immediately? If not, that might trick your OS into burning your battery so quickly.
Otherwise, 12hrs to 24 hours is super amazing, I'm a semi heavy user, and I'll only be able to get 12-14 hours of semi serious use (8 hours standby, 2 hours on off usage, some of that at 100% brightness when i'm outside, and lots of music), end of that I have only 32% left. 24 is pretty amazing, I wouldn't be complaining :laugh:
Well when you simply reboot new stats are generated.

Ok, so I have had today the BBS running on the background. I tried one thing in afternoon, I switched of Wifi. Wifi was off about 3h and when I came back to home I switched wifi back to on. I have still 70% battery!! and about 12h without charging.
BBS alarms:
android, wakeups:83 (Is this much?)
com.google.android.gsf, wakeups:56
com.android.settings, wakeups:13
and the rest of them is under 10
BBS Kernel Wakelock:
wlan_rx_wake: 14m18s
PowerManagerService: 10m57s
and rest is under 4mins
BBS Partial Wakelocks:
AudioOut_3: 3min16s
Twitter sync: 1m56s
BBS Other:
Deep Sleep is about 10.5h
Wifi On/running is about 6h
Is there something wrong or is there something that uses too much battery? Could the battery be "damaged" due it's about 2 years old now?
Sorry for stupid questions but I find it very annoying that sometimes battery life is 5h and sometimes it's way more than 12h with same usage.

What you've got looks fine (which makes sense, since you had good battery life this time). Keep BBS installed. If/when battery life starts tanking, take a look at BBS and see if anything else pops up. If you've got more questions then feel free to post again here.
Although you might miss the customizations of the roms, aospX has great and I mean great, battery life.

Dn3 5v2 I have one question, why the level of battery power is dropping so fast when I don't do anything with the phone in one hour your battery falls by 1% but if I play a game or anything else and it is very quick to use the batteries in one hour, say 50% or is there any option to keep the battery a long time I tried also calibration battery but nothing beter eny idea?!?!?
Agni kernel can help with Battery drain issue... go to their thread
Anyone else experiencing battery drain on the CM13 nightlies? I see a lot of people in the thread talking about better battery life, mine seems to be draining at least 20% over night. I tried a few different nightlies that all exhibited the same kind of battery drain, someone on Reddit suggested my battery would get used to it after a few charge cycles and I might see random drops until then. However now it's been 4 days, the phones still losing 5% battery an hour doing nothing and last night drained almost 30% while I was asleep.
I've got Greenify and BBS but I'm not really sure how to gauge BBS and the drain. If anyone can give me any suggestions or help I'd really appreciate it, as I really can't go back to stock now.
