[Q] bad battery life on my hero - Hero, G2 Touch General

Hey guys, i have a problem concerning the battery life of my HTC Hero with FroydVillain 1.7.3 (Android v2.2.1)
In the last couple of days my battery goes down by 10-12% per hour without even touching the phone. I tried factory reset, wiped sd card and reflashed, flashed CM7 but still the battery issue didn't go away.
I charge it 100% before i go to bed at 11.30 and when i wake up at 7 the phone is completely powered off..
The thing that consumes my battery is the process "Android OS". I read about it on the internet, but all threads were SGS2..
The strange thing is that it's CPU usage time according to the battery stats is 1h 21m after 3 hours of sleep.. Is this normal??
I have everything turned off - wifi, gps, mobile data, auto sync, background sync and still the drain continues.
Has anyone had this kind of issues and possibly a solution?
Or should i buy a new battery?

I have also been experiencing battery issues with Froyd lately, but not to the same degree as you are. My solution was to wipe and install another 2.2.1 based ROM. This new ROM is acting normally in terms of battery life.
With Froyd, my battery was acting "weird" in terms of overall battery life. Once I got about 3 good discharge / charge cycles in a row things seemed to improve.
Another thing to consider is did you recently install any new apps? Some apps don't play nice and cause the phone to not enter sleep state OR cause excess CPU usage.
Some people might say "wipe battery stats" but some Google Engineer / Developer has recently dispelled that myth... https://plus.google.com/u/0/105051985738280261832/posts/FV3LVtdVxPT
Good luck!

It's not from any app. Last night i wiped my sd card, wiped everything from recovery and flashed Froyd. I used it all day without installing anything besided battery graph to monitor my battery usage. it's something from the OS itself i guess..
The funny thing is that it seems that in the past two hours the drain has disappeared and now the battery is reducing by ~1% per hour and i haven't done anything during that time, except 2 calls under a minute each and 1 sms.

How old is ur battery? Did you consider that it might be physically related? Not because of the processes or so?
One more thing I noticed - if I charge by ac outlet, it charges faster, and lasts longer, if I charge by computer usb port, it charges really slowly and battery drains way faster... I don't know about battery life, maybe from ac outlet it dies faster, but 2 years of using it and still 1.5 day of normal use...

Thanks for the replies guys! I found the problem, it was my radio.
I flashed the latest radio and now my hero's battery life is better than before!

Looks like you have a battery problem. OS does not really kill batteries, you can see more or less the same performance if there are no background apps eating your power.
Check these batteries for your Hero. These are top quality and many users vouch for them.
HTC Hero Mugen Power batteries

@saj222 i'm now running the same radio as the one in your signature. before that i was with 09.05 or sth like that..
@porcupineli my hero is second hand with about a year of usage before me. i have it for about 2 months now. Since the phone costed me $90 i don't think i can pay $70 for a battery.. I was thinking of buying this one

Is it any good?

Battery Drain HD2?

Anyone else experiencing excessive battery drain on their HD2?
I am interested to know if this is just my phone or if it actually just chews through that much juice.
I have had windows mobile phones for several years so I know all the basic ways to keep battery drain down.
Stuff that I have generally found:
1. If I keep the screen turned on without it going blank I lose about 1% every 2 minutes.
2. If I am browsing that figure almost doubles.
3. My old Touch HD used about 5% battery overnight when in standby but this phone will go through about 25%.
4. The phone gets really hot when browsing (much hotter than my old Touch HD)
I have tried flashing ROM's and Radios but nothing seems to help.
I am not running any software on the phone that I wasn't running on my old HD1.
I have only had the phone for a week so I am not sure if this is normal but I would be very surprised if HTC released a phone that lasts for only a few hours on one battery.
+1
-1% every 3 minutes
-4% during the night (when i'am sleeping)
MAXIMUM : 45/48 HOURS

I wish I got 2 days
we really need extended battery ,hd1 battery was much more better.
Good mate but yes i agreee HTC has come up with a battery eating device this time around. My device on full charge just gives in around 8-10 hrs. This might be dat my EDGE is on and 7 mails accounts sending mails back and forth.
but truly i think that HTC better look into this very seriously cause more and more ppl are suffering in this battery drain..
Any of flashing roms and radio not helping either... did a complete hard reset but no step up
HTC come with longer battery battery for bigger devices soon......
The only solution i see now is get one of those extra battery worth mind bogling £52.87
I've had this problem ever since flashing to 1.66, I flashed the radio to 2.07.50.27 as this was said to solve the problem but it hasn't made any difference after a few days of use. My battery life used to be significantly better when I was on the original stock ROM, so much so I'm considering going back to it
I also know all the tricks as to clawing back the battery drain, my phone is idle on my desk at work most of the time and I don't use Wi-Fi, all the location stuff is turned off as are weather, stock and other updates plus my screen is set to 30% then off after 60 seconds. Despite all of that I lose 1% every 2-3 minutes
It seems to me that perhaps the radio is checking for reception pretty much constantly rather than say, 5-10 mins perhaps? This used to be a problem on my old Blackberry Storm but a few fimware updates solved it, eventually!
The only other thing I've noticed since the update is that once the battery drops below 50% or so, the drain seems to slow, I don't know if this is perhaps because the phone goes into some sort of semi-power saving mode?
Suggestions/hints welcome! I've had a semi-thorough look into this on the forums and tried most of the suggestions but still the problem remains. Will battery life improve after a few charges perhaps as this was a trait of my Storm's battery, the more you charged it the better the day to day battery life was (and no it wasn't because I had it plugged in all the time! Over time the general charge just seemed to improve when roaming).
Thanks!

You need to indicate what services you have running. Do you have any data services running eg: location services, push mail, weather? all of these have a bearing. In addition, network services can also drain a battery, especially if the signal is weak and the phone have to search for a transmitter, or 3g services.

That is a very interesting comment. Although since upgrading to radio 2.07.51.05_2 I have had very good battery life, I too have noticed a slowdown after 50%

Nothing is turned on, everything is set to manual.
As I stated I know all the basic stuff. I understand that all these things have a bearing on battery loss.
Everything I stated in the first post is for when I have nothing running. The phone is just sitting there running sense, thats all.
I have had my HD2 for a few days now. I am on Vodacom in South Africa.
I have not had a problem with battery life.
Yesterday i unplugged from the charger at 07:00. I spent about 1 and 1/2 hours of talk time on the phone, it was permanently connected to 3g doing weather updates etc. Sent and received a couple of sms's. Also played with a few tweaks and reboots.
When i got home at about 18:00 i had over 30% battery. I then surfed the web for over 2 hours to drain the battery.
try setting Network Selection to Manual

Same here with and without stock ROM.
yeah.. the phone is a battery sucker.... another cons of HD2....
This is very interesting to read because I do not have this problem. When I left my HTC HD2 on last night (I woke up at 4 in the morning to get something to drink and unplugged it) and then woke up at 8, it was at 98%. That means it went from 100% to 98% in 4 hours. Not to bad imo.
I am now at work and it is 15:34, and I am at 87%. I have made some calls, watched some videos, send a few text messages. Not much (I am at work so I got other things to do). So 08:00 (98%) - 15:34 (87%) - that's 7 and a half hours, with some calls, text messages and a video.
I am pretty sure when I get home at 18:30 the battery will still be above 75%. Then I connect to my wifi at home, refresh twitter, weather, browse the web a little bit, check e-mail etc. So that will drain my battery a little more.
But overall I have not had any problems with my battery life. I always make it trough a day, and never have a problem like 'damn my battery is almost done and I am not near a charger'.
Some info that might help:
I do not sync ANYTHING automatically. I still have some things to do with my Vodafone contract and do not have an unlimited plan yet. I only sync at home on my own wifi connection. For me this is not a problem, because I only need to refresh the weather each morning to see what the day is going to be like. Twitter I only do when I have the time. Stocks I do not use.
I have screen brightness set to automatic.
I am on 3G most of the time.
I am running the official 1.66 Dutch ROM.
I have some tweaks, games and programs installed.
I hope you all solve this issue, because it just can not be that my HD2 has a good battery life, and your HD2 not
Kind Regards
EDIT @ 17:00 still 87%.
I am in a 3G 2100 only network (I don't have 2G functionality).
ROM: Artemis 3.0
Radio: 2.06.50.23_3
Customization: Seiya 6.5.5
I don't leave any automatic updates on, except for my e-mail account every 2 hrs.
I never close my connection.
The drainage overnight is -3% (8hrs).
The battery lasts at least 12 hrs of intense usage.
Normally I have to recharge every second day (e.g. I charged last night, I answered a few calls, I did some IM and browsing and I still have 73% left).
For a phone with a 1 GHz processor, a 4.3" screen and a tiny 1250 mAh battery I find the drainage is rather decent.
Mind you, I ALWAYS do at least one full charging cycle to my battery after flashing a new ROM. I mean: full discharge, battery out 1 min, full charging in OFF mode, battery out 2 mins.

I have seen this process recommended a couple of times now. What is the theory behind it if you don't mind me asking?
maybe its also becouse some of us couldnt wait using the hd2 when they got it (like me) before it was fully charged for the first time
anyway my battery life has improved a little bit, i was at 74% this morning and did a lot of browsing, installing, tweaking and now its at 3%. it used to be much worse
I have battery consuming problem from time to time.I did everything:
installed new stock rom 1.66;
transfered all data which phone is using from card to phone memory(pictures,icons,sounds.etc...)
all updates are done manually;
Gprs connection is swiched off on the idle after one min;
One night it is loosing from 2 to 4%;
another from 30 to 40%
and it is eating memory from 10 to 15mb
I think that it is radio which is causing battery drainage so fast(to much communication wit a base stations,because when I am checking spb wireless monitor in the morning,there is no any data traffic.
I hope they can solve problem,because it is getting me mad and crazy
Try setting the screen brightness to 10-20% (on battery powered)
and dim backlight after 10 seconds (on batter powered).
It helps a lot, at least for me.

as far as i know, the battery has an integrated digital circuit (ic) which estimates the state-of-charge (soc). the procedure resets/calibrates the ic to obtain a more accurate estimation. since the radio rom is in charge with the power management (among other things), by changing it you decalibrate the "gauge".
i don't know if i've got the theory right but i tested this myself and it surely works.

ok, my phone battery life is messed up. Help please

Hi guys, this is not another rant post about battery life, but i'm starting to become really
frustrating with it, i tried almost all the solutions provided here on the forum but i can't
simply get the **** out of it. This is my story:
I bought the phone as used around 1 month ago (the guy who sold me the phone used it for around 1
month as well). I was quite satisfied about the device, but i noticed almost immediately the damn
poor battery life. With stock battery, my stats are (this is an average of the last 3 times i
used it):
Average duration: 27 hours
Average display usage: 2.5 hours
Average display %: around 45%
Average standby: Cell 30%, phone 15-16, other apps and android core 1-2
This with the following configuration:
3g off
gps off
background data off
bluetooth off
display brightness set to the minimum
no background applications or live wallpapers
No animations
No vibration feedback
No sounds
No widgets
Removed 5 touchwiz panels out of 7
Wi fi on (actually i noticed some small improvements by leaving it off)
The strange thing is, i noticed that the phone drains a LOT of battery while in standby. During
the night (7-8 hrs standby) my phone can drains up to 20% of the battery life. I read on the
forum that a lot of you guys have a battery drain overnight of around 2-3% which is 10 times
lower than mine.
So i thought about 2 possible causes:
1) Software related(processes or applications running in background)
2) Hardware related (battery ****ed up by the previous owner; phone not going in standby correctly)
Regarding the problem 1) i tried almost every solution provided here on the forum. Updated to new roms (JM5 and JM8) installed ultraslim roms, installed battery saving applications and task killers, performed some exotic "fixes" (removed battery stats file, tried to completely drain the battery following some procedures explained here on the forum). Nothing helped. To check case 2) i bought a cameronsino extended battery. Well with this battery i have exactly twice the duration of the stock battery. Last night i charged it to full before going to bed. This morning, when i woke up, the phone drained 10% (!) of the battery in 8 hours. So the stock battery is not the problem. What should i think then? that My phone is ****ed up? is There no chance to obtain a decent battery life? How is possible that a lot of guys have almost twice my battery life with stock battery?
I guess your phone may not be going into the sleep mode correctly ... try using system panel (from the market) and figure out which rogue app is causing the problem. Mine usually drains 4-5% at night.. (jm8 stock + voodoo)...

[Q] Is this normal battery use?

After 8.5 hrs of sleep I woke up to only 77% battery and when I went to bed it was at 100%... so with ZERO use of the phone it dropped 23%.. seems like a lot to me but is this normal for everyone? I'm running DJ05, Superclean .7, the stable version of geekniks kernel..
If I don't set airplane mode when I go to sleep at night, after 8 hours I will have lost anywhere from 20-30% of my battery. I have terrible coverage at my place, so that is the reason that is causing it. It's not nearly as bad if I turn off sync, but still drops >10%. In airplane mode though, I lost 2-3% over 8 hours last night.
I'm having the same problem, even at work if I take my phone off at full charge and just let it sit, 3hrs later its down 20%. and that's with me not touching it. I'm running the same thing
I turn auto-sync off at night and go to bed with 97% and wake up with 94%. I had battery issues with the xda app before though SEE HERE. No one else seems to have noticed this and it even contiued into DJ05. Might be something to look into or you might discover what is killing you.
good day.
Wipe the battery stats after flashing a kernel or rom. But before you do that, charge the phone to 100%. After wiping battery stats, disconnect the charger and use the phone regularly and let it die out. Then charge it back to 100%, not turning it on. This is a battery calibration, and I always do this after flashing a kernel. I've had instances where I've had the battery go down 1% during the night after doing this.
Rockin' DJ05, Minimal Icognito, Clocked at 1.3Ghz
Eh, it's a bit surprising that display took up 40% while your phone was supposedly asleep; maybe something woke it up during the night and turned the screen on.
That's about what I get over night, but i'm using a not using a custom kernel.
try a different kernel
after trying every kernel available, ive ended up with jt's 11/29 kernel being the absolute best on battery life. im getting around 30 hours with normal use, all other kernels seem to last 12-14 on my phone.
I turned off auto sync and only lost 10%.. So that helped, I also just installed a new kernel so we well see how that runs too..

did the battery calibration and I have had the phone off the charger and using it for about an hour now and it only dropped one percent so far..usually it would be like 15 percent

Edit also erase battery stats
Sent from my SCH-I500 using XDA App
One improvement I have noticed in the battery is it cut off about 1/3 of the time to get a charge.. In about 2 hours I went from 23% to 85% (with the phone running) and there is no way I would have been able to do that when I was running DI01.. IDK if it has anything to do with with the ROM, Kernel, or the fact that I'm on DJ05 but ever since I updated my charge time was cut by 1/3..
Hi there,
as you can see at the screenshot, there is about 3 to 6 Percent CPU Activity, no Device usage and the Battery drained from 100 down to 70% over night. I tried it with
1)Battery Doc (cycle charge)
2)Delete the battery history, and did this
1.Turn your device ON and Charge the device for 8 hours or more
2.Unplug the device and Turn the phone OFF and charge for 1 hour
3.Unplug the device Turn ON wait 2 minutes and Turn OFF and charge for one hour
it looks like that this is normal, right ?
Thanks for your help
what is your time without service? Settings > About Phone > Battery Use > Cell Standby
Thx for the quick response, it is 37%. "Witout service" means, the phone tries to find a signal, or some kind of "sleep mode" ?

It means that it's trying to find a signal. The more it tries to find a signal, the more the battery drains. Try putting it into airplane mode at night, probably will only have a few % lost on the battery then.
Actually it won't matter if you use a custom rom or kernel, smartphone these days will lose battery like crazy if you use heavy net data. I have DX and Droid2, they are the same way with froyo.
Also in case those of who didn't know, whenever you flash a rom, you automatically wipe your battery stats and others.
You definitely shouldn't wipe battery stats when you are on the midway. You should wipe either at nearly dying or completely full. However, wiping battery only "recalibrates," it does not increase the actual battery juice.
Different ROMs/kernels can help you minimize the battery drain as much as possible though by limiting how much is used by the cpu or background apps accessing the net.

Actually no. Different roms have all the same basic data usage, basic google auto-sync. Roms can't control what or how much data will be used by an app. Kernels also can't control how much net data will be utilized. Kernels can shutoff apps based on complier/lowmemkiller fix but that is based on the memory status, not net data usage.
What is the app's name for the battery usage percentage?

Getting 10% Battery Drain/Hour - And Everything is Turned Off!

So somehow my phone did not like the Froyo update, would not boot after install or even a factory wipe.
So Verizon swapped it for a refurbished one, Ive had it for 5 days.
It had 2.2 installed when I got it. However the phone is almost useless for me now, It wont last a full day with nothing on, no GPS, no WiFi, no mobile data, no apps running, only turning it on once or twice during the day to check things and each time I do the battery draining like crazy!
I used to get 5 days out of my old phone, literally, because I am not a big user. I actually did play with the phone the day after I received it, to personalize it, and I drained 50% of the battery in an hour!
This is the same battery as in my phone, you dont get a new battery with the replacement.
I think its a hardware problem with the phone, but a guy at work says its just the 2.2 update, that it slams the battery.
Im going to take it back to Verizon tomorrow and see what they will do for me. If they wont fix this, I will simply revert back to my old flip phone since it lasts 5 days and cancel my data plan.
Keep on them to get that one replaced. Something in your hardware is definitely borked.
Even running WiFi hotspot, I don't see anywhere near that kind of drain (50%/hour). At the very worst, my idle drain was about 9%/hour.
This is not a good thing.

You need to make sure your old battery is calibrated to your new phone.
1 - install CWM recovery.
2 - tonight when you go to bed, power off your phone (power off is not screen off). Plug in your charger and charge overnight, USB charging prefered over wall power charging.
3 - in the morning when 100% charged battery is indicated, boot first into CWM recovery and wipe battery stats, after which boot back into Android then you can check for battery longevity again.

Wiping battery stats seems to be a placebo effect. For anyone with serious drain (several % per hour), wiping battery stats does nothing. Its a shame so many threads are corrupted with this misunderstanding when there are other very real sources of battery drain on froyo ROMS.

It's perfectly normal for some people that wiping batterystats.bin did nothing useful, it's also perfectly normal for others to loose 1/3 of battery capacity from being uncalibrated.
It's definitely perfectly normal for some to loose 10% per hour from being uncalibrated.
This kind of variance often confused people.
After doing some experiments, I think its Froyo.
The reason is I turned off mobile data and the battery only drained 2% in 3 hours. Then I recorded some vids of my daughter and played them back with her and over those 3 hours it only dropped 6%. Seems pretty reasonable. I know in my original post I said I had mobile data off, but I realized I actually hadnt, sorry for the confusion.
So I turned on WiFi and GPS overnight and it only dropped 4% overnight.
So something in Froyo is sucking down huge amounts of battery when mobile data is turned on.
Or its still possible its hardware related, that the data radio runs non stop when its turned on, just seems unlikely.
A guy at work suggested turning off data roaming and turning back on mobile data and seeing what it did.
I've had my phone draining at about 10% per hour before, never did figure out what caused the problem. But I flashed back to stock (following the instructions to get ED01 by flashing back to DL09 and then running the update.zips), and that seems to have fixed it. Since 2.2, I've stayed largely stock - stock kernel and just debloated the stock rom. So far, that's what I've found to give the best battery life for me - 48 hours on a charge on average.
Few things to do/keep in mind:
Clearing the battery stats might not solve the problem, but it can't hurt. Charge the phone to 100%, then turn it off but leave it on the charger. Once the powered off battery indicator on the screen shows 100%, boot into CWM and wipe battery stats. Take it off the charger, turn it on and use it normally until the battery gets down to 5% or below. Charge it back up and you're good to go.
Also, give it a few days/battery cycles to come up to full capacity. I seem to notice shorter battery life immediately after a wipe, but after a few days, it's back to the normal 2 days or so between charges.

Definitely seem to be software problem instead of hardware, I suggest leaving everything on -Wifi, GPS, bluetooth, etc... and disable all data sync only one at a time to check for power usage.

Load up Spare parts and see what it says in Battery History. Under 'Other Usage', it should show that running is less than 100% (depending on your usage patterns, this could read anywhere from 10-90%, but it should never show 100%). Do this after having been unplugged for a while.
If running shows 100%, you have a wake lock, which is forcing the phone to be awake 100% of the time, rather than sleeping and using much less power.
You can use dumpsys power from an su terminal or adb to look and see if you have any locks.
If no locks show up, and running still shows 100% (or even if it doesn't) with mobile data on, then there's definitely something wrong with the data radio, and you should have it swapped.
Don't accept any other answer from either phone CSR or in-store rep. No matter how they try and excuse it, constant 10%/hour and up to 50%/hour drain is completely abnormal.
Ok this is what spare parts says
Running 5.2%
Screen On 3.1%
Phone On 0.5%
Wifi On 77.2%
Wifi running 55.6%
Try this, it will tell you what it causing the drain.

Is that with Mobile Data on? Are you still seeing 10%+/hour drain with those stats?
If you're seeing that kind of running time (which is good), and you're still getting huge drain (which is bad), then your phone is broken and needs to be replaced.

So somehow my phone did not like the Froyo update, would not boot after install or even a factory wipe.
So Verizon swapped it for a refurbished one, Ive had it for 5 days.
It had 2.2 installed when I got it. However the phone is almost useless for me now, It wont last a full day with nothing on, no GPS, no WiFi, no mobile data, no apps running, only turning it on once or twice during the day to check things and each time I do the battery draining like crazy!
I used to get 5 days out of my old phone, literally, because I am not a big user. I actually did play with the phone the day after I received it, to personalize it, and I drained 50% of the battery in an hour!
This is the same battery as in my phone, you dont get a new battery with the replacement.
I think its a hardware problem with the phone, but a guy at work says its just the 2.2 update, that it slams the battery.
Im going to take it back to Verizon tomorrow and see what they will do for me. If they wont fix this, I will simply revert back to my old flip phone since it lasts 5 days and cancel my data plan.

Thats total since all time.
So I had the phone all weekend with wifi and mobile data on, then one day with wifi off, then one day with wifi on, mobile data off.
But the battery was consumed the most with everything on, but still very high with wifi off and mobile data on.
Unfortunately a refurbished phone must be returned within 14 days if there is a problem with it. The remaining time on the 1 year warranty is voided.
just use stock rom DI01package3.tar.md5 and battery is very good for me

According to the OP, you've had it for 5 days as of yesterday, which leaves you a full week+ to get it swapped again.

50% in an hour.. even if u use it the whole time is ridicuoulous.. prob a junk batt.. what are batt temps getting to??
There is a setting in the WiFi area to have the WIFI automatically turn off when the phones screen turns off, you may want to look into it

amazing performance great bat life runz like a dream!!
I just want to report that I've been having similar experiences, and in my case it seems associated with signal strength.
If I'm at home all day (where signal is good, and I'm on wi-fi), my battery life is pretty good. Not as good as it was on 2.1, but acceptable.
But if I'm out driving around, or in a place where the 3G signal is weaker (maybe 2 bars or less, but I haven't really verified that), my phone gets uncomfortably warm in my pocket, and battery usage becomes horrible. I've had the phone drain from full charge to 20% or so in less than two hours.
This problem never happened before I flashed the DL30 Froyo leak. Since then, it has happened on every Froyo ROM I've run, including official ED01 and the community ROM.

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 ?

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.
