I've done a search but can't find anything to do with my issue. I am running L26LEOV2.1_GoldEdition_213_WWE_21899_SE and have been for probably a month. Everything has been running excellent. I've got AS pushmail, weather etc all running and had no issues.
All of a sudden the battery life has disappeared. Noticed my battery at ~30% last night which was strange as I usually charge every night or 2nd night but it's never that low. After about 45mins it was at 8% just sitting idle (no data or anything running).
Did a full charge last night before going to bed and unplugged it. So 100% charged. This morning I found the phone is off, turn it on and its on 0% then shuts down again due to no power. Would only be like 6-8mths old.
I haven't made any software/ROM changes in weeks so I'm fairly sure it is hardware related. Before I go back to stock ROM and send it in for warranty work, does anyone have any suggestions for things to try beforehand? I don't want to go back to an old Nokia while I'm waiting
You could try BattLog to see where/when the rapid power drain is occurring. I've had my battery do the same thing once. I usually get through the work day with 50% left, but one day (without any use) my HD2 was dead before lunch. The problem went away as mysteriously as it arrived. So maybe just give it a few more charges and see if it works itself out. I'm curious if you've noticed any unusual ammount of heat from the battery? It could very well be that it is failing.
I'll try that program but oddly enough today its been ok, using only 10% with a bit of google maps and phone usage in about 10hr.
My Vibrant with full charge died in less than 3 hours. During this period I've only checked email a couple times. No surfing, txting, etc. whatsoever on my side.
I had it on charge all night. I am sure it was charging because when I plugged it in last night it almost got no juice left and then battery displayed full in the morning. I thought; we might have lost power since it was raining last night but that's also impossible since the digital clock in the bedroom never reset.
I came work around 8AM, put my phone on my desk as usual and I got battery low message around 10 AM and finally it died before 11 AM. I did not install any new apps in the last 10 days.
What might be the cause? Anybody else had this problem before?
Kernel, which?
battery needs to be recalibrated.
@kangxi: stock kernel
@proresearch: how do I do it? What's the reason for a need to recalibrate?
Like couple months ago I was able to use my phone unplugged from 7AM to 11PM give or take some. Recently my mileage started dropping for no obvious reason. Nowadays it dies around 8PM. It might be the NOLED app consuming some or maybe brightness settings. On top, today's short battery life. What's going on???

Yes, on a sock phone randomly my phone will only last like 3-4 hours. Last night my phone was at < 25% after being off the charger for 3.5 hours.
Since I was at the rink that means I didn't actually use the phone for at least 2 hours and 10 minutes because I was on the ice for about that long.

Serious Lulz...
It's just a misbehaving process - it's happened to me every once in a while on every ROM I've ever used. Rebooting the phone should fix it.
I had the same issue....on 2 VIBRANTS! I would charge it all night and in the morning it would display "100% charge". But once I disconnected the charger, it would ask to connect the charger. Low battery. I sent the first 2 back. Currently on my 3rd one and its going good.......for now.

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 ?

something is running background...
after i removed all these applications such spare parts and other i got 3 days with light use of course...
with screen off after 3 hours it drops 1% !
and this is fantastic for me!!!

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.
its an android thing

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.
Hey all,
now i'm totally aware of the OS drain bug.
and i've been effected by this depending on ROM. KE1 was the best for me.
anyways i'm on KF1 and it's been good, better response, seems a little quicker to turn off too.
however i'm confused by this issue regarding the battery.
the other day i charged, calibrated and drained, recharged etc. went out and the phone managed 6hours and 47mins on @ 91% thought, brilliant back the the KE1 days, however felt it running, drained it recharged and i'm finding that after 3 hours i'm down to 89%. now i've checked my syncing, only Push is running, and the os is no higher than 8% so what the hell happened? i'm still sitting in my office as the other day, and i've travelled to the same locations, so why is this?
has anyone else had this?
Hi folks,
A few days ago my never rooted & bootloader still locked OP-direct 8/256 6T took the 9.0.11 OTA, updating from the prior 9.0.7. Each night since then I've had a much higher overnight idle drain than before the update.
For the week or so I had the device prior to the update, I would loose 2-3 % total for an ~8-9 hour downtime. Since the update, I'm losing 10-15% overnight.
Accubattery is installed; it didn't give anything useful but it's limited due to lack of root I think. BBS I don't think runs at all without root.
Of the 370mAh used, only about 15 mAh are accounted for by app usage tracked. The device was in deep sleep for 98% of the time. It doesn't show what else has drained the battery anywhere I can see. Cell standby, wifi, etc.. The phone is kept in a place where wifi is reasonably strong in the house; there's cell service here no problem too.
The device has been rebooted a couple times since the update.
Any thoughts on figuring out why the drain is higher now? I've installed nothing new since day one when I got the device.

Haven't noticed any additional drain on 9.0.11 on mine. Yes, you can run BBS unrooted, you just need to do a couple of adb commands to give the app permissions.
I started using the "deep sleep" mode to turn the phone off at midnight, and back on at 6am, since I don't use it overnight
at all. If I unplug it from the charger at 9pm, at 6am (after it turns off at midnight), the battery shows 99%.
OK thanks. I'll first do some investigating after I get BBS running via ADB commands, and consider the deep sleep option as well if I can sort out why it seems to drain a lot at night.
Normally, on my rooted devices, I would backup, flash the latest version (I'm on latest so no problem), factory reset, then restore the apps/data I care about. But without Titanium backup I'm reluctant to wipe so quickly since backup and restore is more involved. Still trying to avoid rooting this one... but may give in and enjoy the ride.
I didn't get around to messing with this yesterday, but overnight last night I only lost 3%. Not sure why the previous two nights were relative disasters. I'll keep monitoring.
I have heard, that sometimes after an update, it might take a day or two for the phone battery level to stabilize.
I don't root/custom flash anymore. (after I stopped buying bloated carrier branded phones). Stock is "good enough"
for my use, but, I've never had a battery drain on stock, but I've heard that some do.
If it continues, it might not hurt to clear the phone cache.
android has to rebuild its optimization cache after every update. it's normal.
No problems here 6t McLaren all stock, 4g all the time, bt always on
try wipe cache from recovery .
Oh yeah & its quite noticeable after using it for over a week even after wiping Dalvik / Art Cache. @funkwizard
As an update, some nights I lose 3% which is sort of my baseline, and other nights I lose up to 15%, and I have no idea why. Apps are using negligible power. Need to get BBS permissions (I'm unrooted) to track it down I think.

I've been losing about 1% an hour overnight and it's very frustrating, not being able to pinpoint the cause. I am rooted and have better battery stats and gsam battery monitor and all I can tell is that Android system is using a lot of power and there are a lot of wakelocks happening up to 40 or 50 times an hour that seems to be keeping my phone from consistently being in deep sleep
Interesting, and thanks for the reply (thanks button hit!).
Today was my first normal day back to work since getting the phone, and it was a busy day so I didn't use the phone much. It was at about 95% charge when I got to work (topped off in the car, so almost full), and 8.5 hours later it had only lost about 17% power, including about an hour of screen on time due to use during the day. So, 7+ hours of standby and an hour actually on in a few minutes here, a few minutes there, using up 17% of the battery is incredible, best phone I ever had. What I don't understand is why sometimes, not others, it uses almost this much power in 9-10 hours sitting alone, unattended, in an area with decent (2-3 bars) cell signal and very strong wifi. Note when it sits at night it always reports ~95+ % deep sleep (typically 98%), so wakelocks aren't my problem as far as I can tell.
I may go ahead and clear the cache through stock recovery and see if that changes anything. Not sure why it would, really, other than some extra power used to rebuild the cache.
It's a busy week so it may be the weekend before I can do much of anything other than observe...
