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

I previously made a thread regarding low battery life.
After a week of use and more testing, here's what I gathered.
(Note: I have GPS, Bluetooth, Wifi always disabled, brightness lowest)
My phone will completely drain out in 6-7 hours.
I found the culprit: Cell Standby
1.) Cell Standby always uses the most battery, often 60%+.
2.) Phone Idle often follows with 30%+.
So, to verify my theory that the screen isn't the issue, I turned on airplane mode.
I proceeded to watch a 1 hour comedy, and battery life dropped from 60% to 50%.
This is lower battery usage than if it were sleeping with cellphone on.
I then noticed that my signal hasn't been good (provider sucks, no choice, all of em here sucks).
So, I placed my phone on, but asleep inside a locker for 2 hours (no signal).
When I took it out, it was very warm at 40+ C and battery life dropped about 20-30% per hour.
I've tried turning 3G off, turning always-connected off or downgrading 2g.
The result has always been the same. It still sucks bigtime.
It seems like Nexus One also has this problem, anyone notice similar problems?
I've googled and been told that this is "normal", because the phone increases power to secure a signal.
However, I've clearly owned phones and placed them in signal-less lockers prior to this, and trust me when I say most of them drop 5% per hour max.
20-30% per hour is horrible, and clearly the phone is overpowering its components.
There are some certain Radios you can flash to improve how your phone uses power to pick up a signal, Requires root access tho.
Can you please point me to those radios? I've already tried updating my radio to latest.
My phone is already rooted.
My battery is a joke and I have tried many different things. I always have to charge it by around 3pm everyday during week as It will almost die on way home.
I take it of charge at 7.30am by 9.30 it could be down to 86% and then it judt continues to drop by 3 It can be between 60 and 50% if lucky, by time i'm tenmins from my house I get 15% and warnings.
I use basically for txt, some net usage and sometimes playing a game 10 - 20 mins tops and or read ten mins of books.
I have all updates off only manual and screen down low etc - doing my head in!

Strange, I always have 3g on, and still play a lot with my hero (games and such)
Still it survives about 36 hours on 1 battery load. Without 3g it holds out for 72 hours.
Post #1 on the thread below seems to have a working solution (re-interpreted below)
It seems to be something to do with the battery stats and charging via usb through PC instead of via the mains.
You have to clear your battery data when your phone has really really low battery (this is probably the MOST IMPORTANT step) (you can do this through recovery mode in amonRa). Once the battery data is clear, switch back on (before plugging in) and drain the battery so that your phone switches off by itself (playing music loud and switching wifi, data connect etc, etc is suggested in the thread).
Once battery has died, plug in your phone WHILE it is STILL OFF, then when the battery shows green (will probably take longer to charge because this time it is getting a full charge), UNPLUG BEFORE you switch it on. and you should notice the significant difference. - Oh yeah make sure you switch off all those data connections and wifi and all those other things that you used to drain the battery - unless you use some of them of course
EXTRA TIP given on the thread: TIP!! Remeber when changing and flashing new roms to unplug the phone from charge *(i.e. unplug from your PC) (edit Bad4ss) * after you boot!
TO answer LennyUK's Q below ( and so that the next page doesn't start to quickly before this suggestion is read ) I think why it is suggested for the first boot after this process to be done while off is because it is already off because of the drain AND because it will get a clean full charge up for the first time after a battery data wipe. Because while it is on it will be depleting the battery even if it is in a small way - after that you can do it whichever way you want *nudge-nudge-wink-wink-say-no-more*

I don't see why the same thing cannot be achieved by charging with the phone on, just as long as you don't change between phone being on or off during the charge i.e. if you start charging with the phone on leave it like that the whole time and visa versa

Can you do this on non rooted phone? How do I get into recovery mode?
I think the analysis is flawed. I also think the stats information doesn't tell you everything. For example, yesterday I had 60% cell standby, 20% WiFi, 20% phone idle. Consumption was 45% in 24 hours.
Previous to yesterday, I had high battery consumption. So yesterday was a breakthrough but YMMV. I removed the PCSCII and the Mail app (I don't sync with Exchange and I don't sync with a PC as such - I don't run Windows). I also disabled auto task killer. I rebooted without being connected via USB to power or to PC. Suddenly power consumption became similar to Modaco ROMs.
Last night, I also disabled the setCPU application and rebooted. 6% battery consumption in 9 hours. 34% cell standby, 33% WiFi, 33% phone idle. Consumption was 45% in 24 hours.
how have you improved battery usage, ive tried resetting battery stats, draining battery, fully charging, using kimera 1.5 and with no wifi no bluetooth, not using phone in few hours it was down to 63% and in 10mins had dropped to 59%
i had similar battery problems but today i changed radio versions into a different one, now i get almost full signal all the time and battery usage is geatly increased (went down 2% in 4 hours as compared to 10%/hour)
so i suggest finding a radio that give you good reception

i unplugged my phone from the charger after doing this at 6am, it had 100% charge
its now10:45 pm, i have 44%charge left...its crazy
before i used to run out of juice around 10 hours after i charged my phone, its not been almost 17 hous and i got 45% left

I will use that radio too seeing as I too am on T-Mobile in the UK. When you say to use the link and suggest doing it, I take it you mean the "get to 10% -> get to recovery mode -> wipe battery info -> reboot and drain battery 'til off -> charge while off and the take off charger once charged and switch on..
'cos I tried that and still having problems - am using the new Villain 4.0 beta2, so maybe the radio change in combination to this is what will work - I'll try it tonight when I get home.
immya : many thanks i now hove phone back
flashed radio 63.18.55.06_6.35.05.31
and lost 1% over night
previously on LOST
radio 63.18.55.06JU_6.35.09.26 lost 56% overnight
perhaps issue with 2.1 roms is the latest radio and not latest kernal
BTW using sensehero at moment as was trying 1.5 roms to get better battery, and that didnt work.
some one maybe sticky this info , if anymore find it a saviour. will report back after work, mayeven be able to use data syncing again
Hi, all. Purchased my Vibrant back in July and always had some battery issues. I figured I'd try one last thing before asking T-Mobile for a battery replacement, so here's what I did. Can someone tell me whether or not this seems normal?
Two days ago, I ODIN'd to JFD to start completely from scratch, then flashed Bionix-V 1.3 non-TouchWiz edition (wiping in the process). The flash was on a completely full battery (plugged into AC, unplugging for the first time after booting into Android).
Here are my usage stats for today:
WiFi off, GPS off, Bluetooth off, auto-rotation off, 3G enabled, brightness around 25%, power saving mode enabled
Gmail/Contacts/Calendar - push, Exchange email - every 15 minutes
Google Talk logged in the whole time
No other syncing applications
Usage consisted mainly of web browsing and around an hour of listening to music through PowerAMP
Charged to 100% overnight
Unplugged for 5 hours, 30 minutes (8:30am to 2pm)
Battery stats: Display 97% (display on 1h 35m), cell standby 3%
Final battery at the end of period: 30%
So, does anyone else get similar battery life on a nearly untouched installation of Bionix? A 70% battery loss with only 1 hour and 30 minutes of screen time seems a little high to me.
That seems like a lot. Try downloading an app called battery left from the market. Charge up to 100 percent and let the app calibrate. It will show you how long a full charge should last. With moderate use I get about 15 to 20 hrs of life with bionix.
Exchange Sync? With what app? I've heard that touchdown is a really bad drain on battery and refreshing every 15 minutes might be a problem. Poweramp for an hour probably cost you 20% battery as well. I'd give a few more cycles to judge your battery life. Compared to my phone, been off the phone since about 8 AM, 20% battery now around midnight. This included 30 minutes of music with the TW player, about 3 hours of display time, a few photos, and about 5 minutes of phone calls, 15-20 text messages. Also some web browsing on 3G and wifi.

Just the Samsung Email app. And I don't think 15 minute polling for new email could cause that much drain... that's something I only enabled recently. This is after a few full battery cycles.
I've also never observed PowerAMP using much more battery than the stock music player.
Sounds like your phone is getting much better battery life.

An hour of PowerAMP drains about 3-4% with flipping through songs, and I have been using this app for several weeks.
Check out system panel also, see what apps you have running in the background.

As I mentioned, this is a fresh installation of Bionix-V 1.3-- I haven't added on any apps that could possibly be responsible for the battery drain. I've used System Panel in the past to evaluate battery issues with little success.
I've had bionix-v 1.3 for about 3 days now.
This afternoon i pulled it off the charger at 90%. Now, 7 hours later, i'm at 69% with:
display: 79%
cell standby: 16%
phone idle: 4%
Today was pretty light use though. Just about 20 texts, 30 min. of web browsing, 5 min. on phone calls. I also put my display brightness down all the way and freeze a few apps using TiB.
Normally though, i make it through the entire day (18 hours) with one charge and what i consider to be 'average' or medium usage.
Hi all,
Just curious if any Bell users are experiencing the same battery performance as I am.
My phone is complete stock. The only change I've made is using launcher pro.
I leave for work on a full charge at 7am and by 5pm, I'm down to 30% after light to moderate use. By this I mean, sending 20-30 txt msgs, checking my email and twitter half a dozen times.
It seems like poor performance to me.
Thanks in advance for any comments.
your battery is bad because you have emails, calendar, weather, and news constantly syncing throughout the day. theres so many battery threads, do a search and and check out the developer forums and you will find out what you can do.
Try changing your browser settings on the phone to load plug-ins "on demand". This made a significant improvement for me. I went from 20-30% by 5pm to having 70+% by 5pm. I'm on day 2 of light useage and still at 50% (24+ hours so far)
If that doesn't fix it, charge that beast to full, unplug it, and do a factory reset. Then let it drain till she powers off.
Do a full charge (8-10 hrs) up and full drain (use phone till it shuts off by itself) a couple of times and you should get amazing battery life. When doing the charging turn your phone off and just plug in the wall charger.
When the battery has finished charging do a factory reset once (don't need to do it every time you cycle battery).
I didn't do this initially and my phone had like maybe 8-9 hrs of battery life on the very first charge. After I did a couple of full cycles my phone would last me almost 2 days with moderate use. I have the Bell version of the phone as well.
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??
Riz
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??

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

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
