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.

From last 3 days battery drain of my Micromax Canvas HD A116 has been tremendous especially at night in standby mode. Before I go to sleep at around 12:30 a.m When I check the battery it's between 40% - 50% and when I get up at 7 a.m in the morning just to find the cell has got switched off. The drain is so heavy that it doesn't even power up for the alarm. In the attached pic you can see the complete drain marked in red color and the cell standby and phone idle are the highest battery consumer.
Previously I thought it was BBM messenger which is the battery consumer so I removed it but in vain as the problem still continues. Kindly help as what I need to do to resolve this problem.
Device: Micromax Canvas HD A116
ROM: JB 4.2.1
Service Provider: Reliance Communication
Network Mode: 2G/3G

Download and install Juice Defender from Playstore. It won't drain your battery again at night.

Problem looks to be with 4.4 apps like hangout etc. , read in some place. Recollect once if on same time line you installed these?

Well I really don't think the drain is due to application as if you see in my previous screenshot I am charging the handset and by 12:30 in afternoon I charged it completely to 100%. That charge last for almost 12 and 1/2 hour without any recharge as you can see in the current screen shot attached even after 11 hours battery was at 47% and then some what near 35% it made a steep drop to 15%(strange) and then it lasted for like an hour or so. Beside that my data connection was continuously on and all sync was on. My talktime was of 4 hour in that period and yet it sustained also gaming to some extent like for 20 min. or so and again in night was connected to my wifi yet it survived this huge load.
So around 1 am in midnight it got drained completely and then I put it on charge in switched off mode, at around 4:45 am in morning I removed it from charge with battery completely charged(100%) and then I switched it on and went back to sleep. After 2hr i.e. at 7 am when I woke up the battery went down to 89% without a single use(I didn't even unlock the phone after I switched it on) almost 11% battery drain is seen in stand by mode and that's the point of concern.
So one thing is for sure the drain is not because of any application also in last few days it's my observation that the place where I keep my mobile used to be covered properly under HSDPA n/w and always use to have H or H+ as the network symbol but now it shows E and it might be switching to and fro and I guess that might be the one reason for the drain.
Kindly share your view on this and also your guidance if you have any

I had the same issue except, in my case when it reached 25%, it dropped very quickly. So I calibrated my battery and its working fine now. This app is available in play store free of cost but you have to rooted to use it.

Hit thanks if I helped.
My DNA battery has gone crazy. Last night the battery was at 66%, I restarted it and the battery went up to 76%. Today, the battery was at 33%, I rebooted it and the battery dropped to 17%. After that I rebooted it again to see if it would go back up and it dropped to 14%. So I did it one last time and that battery then went up to 24%. I dont get it and on top of that my battery life has been terrible recently.
To try to extend it I have installed Lux to manage the screen brightness, I have turned off backup and Google Location Service.
I got Nova Launcher yesterday to see if that helps, I'm using Greenify to close apps and CleanMaster to get rid of junk. I dont use Google Now or have any apps sync/receive notifications besides Messages and Phone. I can't get through the day and I don't use my phone from 7am to 12 in the afternoon.
I have 25 apps installed from Google Play and all the bloatware and useless apps disabled. I use Next Browser instead of Stock/Chrome
Any solutions or suggestions

Maybe just try to do full cycles with the batter to re-calibrate it, charge it up 100%+ and drain it 99%, rinse/repeat a few times.

Ive read that you arent supposed to drain the battery and this phone is unpredictable for when it will turn off from a low battery.
Sometimes it turns off at 8%, sometimes it might turn off at 2%

You're right about draining the battery however we cannot fully drain these batteries. The system shuts the phone down when it hits a certain level, however you can still power the device back on after it does this, thus the battery still has charge and not fully drained.
And yes they can be unpredictable.
Mine will shut down when it gets to about 5 percent but I was using it one time and it went from 8 to 2 in a second and powered itself down. I think they all act weird when they get really low but your issue sounds like the battery is on its last leg.

According to your battery stats, what's draining the battery the most? Also download GSam battery stats to get a more detailed look at the apps and services that are consuming battery.
Maybe your battery is past its prime, but you want to be sure its not an app or service draining things before giving up.
My Droid 3 and 4 are still going strong as long as I charge them fully and then periodically drain them to 10%.
When you sleep, does your phone sleep, or does it stay up all night and crunch 1s and 0s? Rate this thread to express how you deem the speed at which the Huawei Mate 9's battery drains under standby conditions. A higher rating indicates that when the phone is not in use, the battery drains minimally.
Then, drop a comment if you have anything to add!
4% during my sleep, wifi and sound are on, impressed

During sleep, doing nothing < 0.4%/h
Standby drain is 1%/hour. Deep sleep is also bad. Firmware ver C185B110.
I'm not sure if is related to any app I use

Same as me.. hoping it gets better though..
from 23:00 to 9:00 battery drained from 14 to 8% with everything on (2 sims, 3g&4g+, wifi on - not connected, location on.
I think that at some level depends on how long we have it. I find that the the power consumption raises as day goes by.
I loose 1-2% of battery per night. Tweaked settings a bit. . Wifi/Bluetooth/NFC off during night. Check which apps are are eating your MaH in battery usage details during night time. For example my biggest eaters are Google Fit with approx 5 MaH per night and Swift Keyboard with about same + Hardware consumption of course, phone standby, device idle,... I have set most my applications to automatically close after I lock my screen. So I don't have to do that manually.
3% in 9 hours. 3 apps left running in the background (FB, FB messenger, and trigger). BT off, Wifi & mobile data on (2 active SIMs).
Very simple solution how to conserve power and increase standby time during your sleep is to turn off wifi and bluethooth. Unless it's critical for you during your sleep. For example today I went to sleep with 66% battery left, slept 9 hours and woke up with 66%. Less than 1% battery consumed over 9 hours.
I will try this.. thanks
I just got this phone 3 days ago, on its second charge and I went to bed last night at 11 o clock. Went from 92 to 91 percent when I got up at half Pas 6 this morning. Can't complain there
Still on the 126 firmware tho.
Edit/
So I got the update to 138 a few days ago and things looked real bad. At first, for some reason the battery got about 20 percent worse than at 126. I'm not a Facebook user so I can't blame Facebook nor messenger for that, I don't have those apps installed.
Now after a few days battery had gotten a lot better with this firmware and now I can say it's pretty much the same as the 126 update. Maybe even better!

My standby drain is pretty bad for a phone with such a huge battery. I just wiped the phone yesterday (for the third time), didn't recover from backup but set it up as a new phone to avoid the Google Sync problems I previously had. I installed just 8 apps: Twitter, Whatsapp, Telegram, Snapseed, Yelp, Youtube Studio and Spotify.
After 50% have gone, I have 2:50min of screen on time. As you can see, the phone wakes up way too often. In the very beginning of the graph I just unplugged the phone and let it rest. It seemed to deep sleep, but still lost about 6%. I also turned off wifi for an hour somewhere in the middle, but it doesn't show up. The battery life could be just so much better.. It's just disappointing.
I put the screenshots in the Google Drive. Can't post them here for some reason?! https://drive.google.com/open?id=0BzAs5-iV39iCTUpnYmpiLXJ5WEk
My standby drain is under 0,3%. Really good.
