Horrible battery life

My Huawei has a horrible battery life. I'm using stock rom (rooted of course) and the battery drains really fast, like 5-10% an hour even in sleep mode. I have used a battery calibration app recommended by someone here in xda, but I don't think it made any difference. My last Android phone used around 1% an hour, even with data and sync on, but with pretty much the same settings, I can hardly make it through the day with my Huawei.
So, what to do? I don't need the battery to last for days, but having to recharge twice a day at worst is just too much.

My battery drops around 7-10% overnight.
Probably a defective cell?

mine after i installed custom rom (b160) and a battery calibartion in flight mode during my sleep after 7 hours that passed and woke up it was 1% dropped and now 7 almost hours afterwards in normal mode it has dropped 7% with very light use of course...
i want to say just that with gsm active it drained 5% more than in flight mode...
so something must be going wrong , like you don't have a good signal and it uses much power to keep your connection alive and have better signal....
i must say that i have a profile with setcpu when the screen is off with min 122 and max 460...
and just for the record i think that with custom rom also mine was dropping more...
i don't know why although...

Noticed this myself. i use spotify alot on the phone, walking, bicycling, at the gym. and it drains a whole lot of power even in offline mode. but if i set it in flight mode the phone last for hours and hours without even dropping 5-10% of power. but when gsm or data traffic is on the battery life just drains out so quickly! so it is definitly something serously wrong in this rom. Im hoping gingerbread is coming soon to this phone, so maybe all these small issues has been fixed.

I've found highly variable battery life. Sometimes it's awful, almost 50% overnight when it's sleeping on my nightstand, other times it's much better and only drops 7-10% under those conditions.
One thing is Google Maps, even when not in use it seems to suck battery like crazy if it's loaded (and it has a habit of getting loaded even when you don't run it or any apps that use it). There's a long thread on this in the Google support forums, but no sign of a fix from Google yet.
I've found doing a 'force stop' on Maps if it's running often helps, another thing is to reboot the phone after you charge it, that seems to fix it for several days sometimes, but then it starts sucking juice again for no apparent reason, so I tend to reboot it after each recharge. There can also be other apps that due to bugs can suck battery, for a while there app killer did this but the author put a fix out pretty quick and it shouldn't be an issue now.
Just noticed that there's an Android update from Huawei now available for download, maybe that'll fix some of the irritations and help with battery life; I'm off to install it!

where can you find that update? through phone's settings->check for update (in my case it says i got the latest version) or online?

My phone has been on for nearly 48 hours.. charging it right now. I played, connected to wifi, browsed the net, facebook, gmail etc.. and I really played hard on it for a few hours.
30mins ago it switched off, dead battery.. I'm quite pleased with the battery life

Exactly the same problem here. I formatted now both the internal and external SD card, let's see if that helps.
edit: No it doesn't. The problem seems to be that my phone doesn't sleep properly. I charged it to full, then turned the screen off for one hour. App called Spart Parts shows that since last unplugged, time spent without sleeping is 36m.

it took mine 2 weeks to get to the full battery life. now i get 36-48 hours from it.

After 5 weeks i get about 12hrs. No GPS, no 3G. About 10min ago i took the charging cable off. Now Battery History in Spare Parts show that "Since last unplugged" time spent without sleeping is 10m 33s (99.9998%), and time spent with screen on is 3m 23s.

im thinking of buying this phone is it available in India ? also can this device be rooted n what about the custom roms ? are they available as there is nthng on XDA :'( . And what about its battery life even being 1500mah is it so awful ?

Now after factory reset it seems that this is fixed. Over night with Wi-Fi and all sync's enabled, it took about 20% which is quite ok.

The problem is back... For some unknown reason the phone doesn't go to sleep and starts to use more battery.
Battery History:
Other usage, since last unplugged:
Running (100%)
Screen on (3,2%)
Partial wake usage, since last unplugged:
Android System: Total time: 13s
Dialer: Total time: 0s
Maps: Total time: 0s
It seems that reboot helps with this every time. After reboot, running-% is 32.9 when screen on is 6.5%. It would still be interesting and helpful to know what causes this.

Do you mean it's a common bug, or is it normal thing for Android to not go to sleep after few hours of using the phone?

That's not true. My battery history shows that correct(as far as I can perceive) running time.

I get most of the time also. But after charging, at one point (after some time) for some reason the time spent without sleeping goes to 99%. The problem is, that the partial wake usage doesn't show that something is wrong. Usually restart helps, but sometimes it can be already late, because 100% running has already taken quite much of the battery.
Also, when the time spent without sleeping is 99% or 100%, the CPU is still NOT in heavy use. So something just prevents the phone to go to sleep mode, and it seems that it is not the CPU that causes it.

I got it through the phone, it was the 2.2.1 B136SP02 update. Not online at Huawei website. It doesn't seem to have improved battery life alas (or the frequent WiFi dropouts I've had since new, particularly while downloading app updates). Main feature of the update is WiFi tethering/hotspot support, at last...

What seems to have worked for me after a couple of weeks++ of REALLY crappy battery life is a battery stats wipe.
FullCharge while the phone was off. First boot in recovery, battery wipe and then i just let it run close to dry before the first charge (almost 48 hours of medium use). Note here that i am now using the charger that came with the phone because i noticed that my generic usb one had an output of 0.7A instead of the full 1A of the factory charger.
Another point arose however. Does anyone else have stability issues when battery drops below 25%? I am talking about some serious crash/reboot/lag/noradio issues.

Good post thanks.
Got 1 tip Ive noticed recently and that is to ''Reboot your phone at very least once a week''. Reason for this as Ive left it for 2 weeks with out reboot and charged up full and went to work which was 40 mins away. Then noticed that battery was at 80%. So an hour later was down to 50%. I checked my running services and nothing running only standard android stuff. So I rebooted and then was on 40% and that lasted me 11hrs of radio while at work with 4 calls I made.
I know you can ''wipe battery stats'' in Recovery but I didn't use it this time but rebooting the phone stopped the massive drain.
May be different for you?

I wiped the battery stats when it was fully charged, and now it lasts 2 days without recharge. I'm also running juice defender for some more power saving.

Galaxy S5 plus battery drain (G901F)

Hello everyone,
I received my S5 plus about 4 weeks ago, (After an overheating LG G3 and a unresponsive Oppo Find 7a i took this one) and all the time I have had a battery drain.
The first one was fixed with a factory reset.
After that the Android System and Android OS were draining battery. At one moment it became to mutch, so I did an reset again.
It was normal for a day an a half, after that the phone was awake/active all the time.
Now I still have the same thing, Android OS and System (Espescially System) are using a lot of battery.
here you have some samples
No photos because im still new
But Gsam says the Android System is using 40% and The android OS is using 20%
Al the other apps are using below 2%
Samsung battery says the System is using 10% and the OS 8%
I am running Android 5.0.2
Anything I can do? I disabled all of Samsung bloatware and other thing but it doesn't help.
I am not rooted and i dont want to. (Lose warranty)

Note 4 battery problem after flashing some custom roms

Hi everyone, i have problem with my note 4, battery drops from 11 % to 3% very fast and charges after 85% very slow.. this problems started 2 days ago when i flashed dn5 custom rom i thought it was rom problem and flashed sixperience rom but still i have same issue also i tried battery calibration but again.... what can i do???? and my screen on time is only 3 hour. please help me, thanks.

Have you checked what's eating away at your battery? Settings => Battery (Here you should be able to see if anything is causing a drain).
If the settings screen doesn't seem to show anything, you could try BetterBatteryStats (This app will be able to tell you everything that's going on regarding running processes, wakelocks,... You should give it a day or so from a fully charged battery.)
And if even BBS doesn't show anything, I'd flash the stock firmware again (And check if it isn't the battery).

Well, in all fairness, mine is running CM 12.1, and SOT is a bit under 4hrs. Which isn't fantastic either. Quickcharge does slow down a bit after a certain percentage. You could try a new battery, but might be a waste of money.
I'm afraid I can't help you any further, maybe someone else can.

did u change ur battey? im going to buy anker battery as i know they have good ones

I am facing exactly the same problem .. I don't think buying a new battery will solve this problem.
My mobile is charging by AC very very slow and sometimes it stuck at certain percentage for hours and I tried many things but I am still facing this problem... While recharging if I removed the battery and put it again, the phone shows me that it is 100% while it was not 100% at all.
I wish someone can help us about this problem or if any of u guys tried a new battery and the problem has been solved, so please feed us back in here

well after 3 4 days (i mean after flashing sixperience rom) everything is ok. discharge to 0% then wait and full charge + calibrate battery may fix issue. but still dont like screen on time. only up to 3.5 4 hours

That sounds weard...
I mean the good thing is we could change the battery.

I have a feeling this is not battery issue. it's exynos + apps running on the background. Try to root + disable unnecessary apps (maybe Android 4.4 Would give you higher SOT). I had Note 3 previously and SOT was at the level of around 6 hrs (snap processor) - now on exynos it's around 4 hrs on stock firmware (5.1.1).

My battery just drained from 100% to 13%

Hello guys, I have a problem
So, I charged my Nokia 6 ( with his own charger ) until it was 100%. and after that, I unplugged it from the charger.
After that I went to sleep for 8 hours and after that I went somewhere for another 6 hours ( I forgot my phone at home, didn't use it at all)
When I got home and unlocked my phone, the battery was at 13%. When I opened the battery drain history, Android System was 43% and the aplication KIK was 13%.
I just bought this phone last month and it this scared me..did someone else had this problem? Or is it a factory issue?
Yeah I admit, when I go to work, I use the phone a lot, like using facebook, messenger etc but how can I say this, in 8 hours at work, I use it and it goes from 100% battery to 30%.....
Can someone help?

I think it was before update( I.e September) I too faced this issue before updating and now it is good (but mine was 100-30 and no usage for about 12hrs or more)

well I didn't have any updates, my Nokia6 is still on 7.1.1 and in that night, I didn't have my mobile data on nore the wifi. So it was simply on idle :s but since then, the problem didn't appear...

Ok I understand it (may) happen I think u need to use a original charger
