Hi,
I've been noticing that my Hero has been gulping battery down VERY fast.
In general, the battery lasts 7-8 hrs, which is not acceptable (I'm out for 12+ hrs).
My usage is not heavy. Wifi, Bluetooth and GPS are rarely, if ever, on.
I do read some news and surf the web a little but only for 2-3 of those 7-8 hrs.
Is my battery life normal?
I've been reading people achieving 12+ hours with their stock battery...
2 or 3 hours websurfing is very heavy on the battery, much more so than phone calls. One of the biggest drains is the screen and you having it on for 2 - 3 hours is going to drain the battery I guess
Seems very poor, much poorer than my iDevice that I use more frequently.
Today, after flashing the 2.1 ROM, it has gotten worse.
Battery's down to 40% in 6 hours, and Battery Usage shows 50% phone idle, 50% cell standby.
I've not even touched the phone since unplugging it 6 hours ago ;S
Is it possible I've a defective battery?
If your battery is down to 40% after 6 hours of it being idle (no screen but switched on) then either you have some power hungry app(s) running in the background or the battery is defective.
At the moment my battery is showing 40%. It was last charged about 40 hours ago, and I have had it switched on the whole time with some light use, picking up emails in the background and occassionally switching the screen on.
I ran task killer and sync was off.
One thing I didn't do was charge it for 10-13 hours straight on first charge; I just unplugged it when the led turned green in ~4 hours (impatient...).
Could this have affected battery life?
Nope - when the LED is green it is fully charged. No minimum charge times suggested in the manual.

That is amazing battery life, I never get more than 24 hours with similar use... what ROM and radio are you using Peter? Also, where are you and what network are you on?
I am in UK on Orange, and have standard Orange ROM and Radio - not the latest one but the one they had before 2.73.61.5.
I have read lots of complaints about battery life, but I think mine is fine for a smartphone. I am a relatively light user of a phone - don't do lots of surfing or watching videos. A few phone calls, very few texts, checking emails and listening to some music is all I normally do with it. The other thing I do use it for is I always have the sat nav on while I am driving, but in that case it is plugged into my Brodit mount and charging from the car.
This latest spell may have been helped because I have not been out over those 40 hours - spent the weekend at home, which means that the Hero has been logged into wifi rather than trying to use mobile data. And not used it to make calls or texts or used the music player.
I notice keep Internet connection active take a lot of battery. Go to settings and turn it off and try to see whether the problem exist. It'll will take you a few seconds to re-establish the connecting whenever you need it... not so unbearable considering it'll save a lot of battery.
Same, I notice the mobile chip is using abnormal amounts of battery.
In the morning I watched a 40 minute episode of drama.
Battery dove from 100% to 65%.
To preserve battery life, I turned Airplane mode on.
When I was done with the episode, there was still 55% battery left!
I'm pretty shocked at the battery drain.
I'm using one of the new 2.1 ROMs. They're known for having a bit of a battery-hunger. I solved it by installing the app Ultimatejuice from Market. it's a pay app, but it's worth it. It's also another app called juicedefender (free, less options) that I used before I bought the Ultimate. It also worked good! Now my battery lasts the whole day without any problem
Upgraded to KE7 yesterday using Odin.
Before going to bed around midnight, I had the phone connected to charger for a couple of hours, so the battery was fully charged at a hundred %.
Before turning in, I disconnected the charger, and disabled Wifi (generally battery life is worse on mobile data then Wifi, in my experience atleast). Around 8 am I woke and found the phone had switced itself off, completely drained. The phone that was fully charged, should've been on idle most of the time. I have 2 exchange account configured for Push, 1 F/book account, Whatsapp, Tango, NO live widgets. I think these are the main users of data/background processes. The phone had died in 8 hours, possibly less as I'm not sure exactly when it had switched off.
Put it back on charge again, left it charging for a few hours, around noon time, it was back up to a 100%, so, disconnected charger, now. 8 hours, 21 minutes later, the battery is sitting with 44% left, so, I would get circa 15 hours of usage on Wifi.
Under Wifi, 60% of the battery usage comes form Android OS...
Has anyone else noticed the same, iis there any fix for this... has Samsung fixed anything worthwhile in the jump from KE2 to KE7??

Hadn't quite figured what was causing pretty good battery in some circumstances and very poor in others. This would explain it and would be consistent with the stuff I was doing when I noticed the quickest drain.
Can't offer definitive proof, but certainly a very plausible working hypothesis. Solution anyone??

I think you should test it a few more times before concluding that it's due to mobile data vs wifi...?
I have just logged on to this forum to complain about the same issue! After KE7 battery has gone worse than before!!!!

Boogweed,
Normally yes.. but I've always noted worse battery performance on gprs/3g than WiFi, which is why I tested the phone mobile data at night.
Its a recurring problem.

Battery life has been pretty great on my EVO 3D using juice defender and SetCPU.
Switched to Sprint for this thing yesterday and I gotta agree. Coming from an SGS I've learned to be paranoid about my battery life, so when I barely see the battery draining off this thing I have myself convinced that it HAS to be a bug lol
How is your awake time so low compared to your up time!!
How can I see what is keeping my phone awake.

Because in the time that the phone has actually been powered on, its only been in use 4 hours. If he had been really using it, the battery would be down more than it is, but its still good battery life.
I agree, of all the devices have had so far, HERO, EVO 4G, EPIC, 3D. the 3D (comparing all of them on stock) has had the best battery life of them all. Heck even my Rooted EPIC with SFR 1.1.1 didnt get quite as good battery life, and it was rooted.
you guys know that the 3d has a larger battery than all those phones listed right?
still has the best battery i've used.
Well you will get amazing battery life turning the display brightness down anyday though. Still i have to agree this phone has great battery life. On auto my biggest battery drainer is the display but still I can get through all day with the phone. I unplugged the phone yesterday at 6 in the morning and at 9 at night I still had 20% battery life and that is with medium usage.
you barely used it. i can get great standby time too. but once i have the screen on and turn data on or a game you drop something like 10 percent an hour.
in the past 53 minutes ive had my screen on for 17 minutes. lost 8 percent.
Up Time: 37:49:30
Awake Time: 05:17:50
Battery Remaining - 52%
Impressed with battery life thus far.
I think the battery life is even better at 1.5 GHz and stock voltage.
well you guys are lucky cause my battery life stinks. medium usage, brightness at 30% sync accounts knocked back , no 4g and im getting 4-5 hours out of this thing which I think is terrible. something is wrong. Anyone else experiencing the same ?
how much of the battery is listed as "display"? last week while i was working i would leave my phone in my truck and come check on it an hour later to notice a 30%+ drop in battery. it would die after only being unplugged for 5 hours. but then i realized my screen wasn't ever turning off so if i got a text, notification, etc. that turned my screen on, my battery got drained idling in my truck.
rebooting usually fixed it but i think it was one of the early temp roots that really was causing it because i don't think it happens anymore
under battery usage the display is 75% percent of drain the rest is voice calls
mine is stock, no root here
Wow thats crazy my phone has an up time of 87 hours and an awake time of 69, i still have 95% battery left.
I'm dominating all of you.
Or maybe those two numbers mean nothing besides how long the phone has been on, and not anything to do with battery

Battery life is awesome on this phone. I still think its too good to be true. When I turn off mobile data, I can easily go a whole weekend without charging my phone. And that's with sending and receiving over a thousand texts, taking random drunken pics and vids, and talking on the phone for long periods of time. I only turn on mobile data when I need to sync up for fb, email and such or look up stuff, and I've pretty much been charging my phone every other day, and sometimes on the 3rd day. This alone makes this phone priceless to me and I've never been so satisfied with a phone like I am now.

All and all battery life on this phone is average. It lasts the same 9-10 hours as every other android i've owned. I spend the same amount of time doing the same things day in day out.
The only android I've ever noticed an exception was the NS4G and it had crazy battery life, easily 20 hours.
I think its better to post time the display or voice calls was used rather than percentage.
I'm at about 13 hrs usage with about 2hrs and 50 minutes with the display on. Probably close to 20% battery left

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.
Hi guys, will need your help.
would love to get your input in your battery discharge overnight when the prime is not in use. i noticed that my prime drops about 10% overnight. i highly doubt this is normal.
my ipad 2 drops about 1% in a day if not used...
also i noticed that when docked, the dock drops about 2% a day and thats even if my prime is fully charged and not in use.
your input would be appreciated.
The last time I checked this -- on the .13 release -- mine drops 1-2% overnight. However, I'm very conservative on power usage and do things like turn off the Wifi when I am not going to be directly using it. I don't have Bluetooth on either and have all apps set to sync manually as far as is possible.
Mine dropped about 2% last night, with Wifi on, Bluetooth off, and apps set to auto-update.
Mine drops 1-2% an hour when idle and docked with wifi off and power savings mode. When it's not docked the battery is much better in idle. When wifi is on the battery idle sucks
