Weird battery problems...

I used to get OK battery times on this phone, it easily lasted over 60 hours without really doing anything to it apart from disabling wifi + bluetooth.
Then i rooted it and using SetCPU i got 4 - 5 days battery, very good.
Now, for no reason at all, it suddenly lasts about 24 hours with very little usage, and nothing has been changed. I've tried uninstalling everything and using SetCPU + Juice Defender + Disabled Wifi and Bluetooth. No help. Screen brightness is on 60%, but like i say it dont get used much so that wont have much effect.
Whats going on? My sister also has this phone and her battery is a joke, lasts about 14 hours at most, sometimes not even her whole work hours, and ive tried everything to get it to last longer, even rooted it and put SetCPU on there, disabled everything, and uninstalled everything. Un-rooted or rooted phone makes no difference.
I know lots of others have battery problems too... something seems really wrong with these phones, i dont know if it's android 1.6 or the hardware. But i'm starting to think they are utter **** and should not have been released.
Any suggestions would be good, thanks...

More details please...

There are ways to find out whats consuming the battery on your phone. Settings-> About Phone-> Battery use, is one.
You can use the application called "Spare parts" to get more details on battery history.
By your own admission, you have seen the battery last upto 4-5 days, there could be many different things that may have happened between then and now. Trust me, 1.6 and the hardware are fine so you can tone it down a bit.
The forums have several threads on this topic so read them. Monitor your battery usage and try to isolate the problem.
At the worst, your battery could be the culprit... its not unheard of. If you can track it down to the battery, you can ask for a replacement if your phone is still under warranty.

It could be the battery, but what about my sisters phone? she already purchased a 2nd battery because the phone did not last the whole work day. So it's highly unlikely that we have 3 batteries between us that are defective.
The point is these issues should not exist in the first place, i shouldn't have to monitor the batterry for hours and spend hours messing around trying to get a battery to last longer. Everything has been uninstalled anyway so i can only see basic phone functions draining the battery like Cell Standby, Display, and Calls. Same with Spare Parts.
We're both in different area's too, and signal is good in both, so it's not like the phone is constantly searching for a signal either. Even our networks are different.
I've already read many other threads but nothing has really helped. Tried Helix Launcher and other interfaces too.
So i'm having to disagree and say it might be a problem with the hardware or Android on this specific hardware, which would make more sense, i mean something with software would more likely be the cause of this when it's been proven it can last longer. Just a quick google search will show how widespread this is, and the guy at my local phone store even brought this issue up without me even asking about it.
I'll keep trying though, and thanks for your help.

JI6 update: a *serious* let-down, in my opinion

So, this post is 1/2 "rant" and 1/2 "any ideas", but the JI6 Update has been (in my opinion) a very serious letdown.
First of all, I can't be alone in thinking that the late-September update from Samsung would be a full-blown upgrade to Froyo. Obviously it's not. I guess we'll wait awhile before that's released
Secondly, I'm one of those sorry saps that had the update soft-brick my phone. It took me a few days to get around to the ODIN fix (bumping me back to "stock"), but it was still a royal pain.
Thirdly, I've already seen some issues that I didn't have before. For instance, the phone "froze" on me while sitting at home: no screen response. I had to pull the battery and power up again. Nice!
Finally, the battery life is utterly horrible for me -- and I'm not sure why. Currently at 26% battery life (now 8h 4m since unplugged). 34% of the usage is "display", which has been on for 28m total. 22% is cell standby. 15% is phone idle. 10% is voice calls (2m 10s of that). 8% is the Android System. So on and so forth. Basically, I've *hardly* used my phone today, yet the battery isn't going to last thru to the afternoon. I have 6 active applications, with none of them hitting the CPU at all currently. Best of all? The battery icon looks like I'm about 1/2 full, so evidently Samsung couldn't be bothered to make that icon accurate. I know about the battery icon mods out there (I've used 'em), but I figured Samsung would take care of that.
Sorry for the venting, folks. Is anyone else seeing similar stuff? Any ideas on the lame battery life??
Thanks,
Yip

For me Android 2.1 which samsung released in Galaxy S is exactly like Windows Vista ! No matter how many updates you release for it still will make your phone **** !
The only option is to release a full new OS which is Windows 7 = Froyo !

Better than Windows NT = 1.6

Getting your phone bricked isnt the updates fault, there are hundreds of threads out there and reading just one couldve given you signs of warning.
As for your battery life, I am willing to bet your phone screen is full of widgets. Try limiting those, as well as automated syncing. I get excellent battery life that can EASILY last me the whole day (I actually find myself running avatar/pandora at the end of the night just to drain it so I can recharge the battery).
However, I do agree that the inaccurate battery reading should have been fixed a long time ago (or at least in this update) and that froyo should have been included with the release of this phone.

Your cell standy is too high which means you have things constantly using the cell signal to pull data, thus draining your battery. Right now I'm at 72% with 67% display, 14% voice calls, and 9% cell standby. Been unplugged for 3 and a half hours.
Not great but I'm purposely trying to let it die because I'm reconditioning.

Ha! You may just be right on that. Eclair seems like a fairly lame version of Android, if you ask me. Not horrible, but not great.

"Signs of warning" means nothing, my friend. There are folks who didn't even *root* that got soft-bricked with this update. It was (somehow) poorly handled.
As for your widgets comment, well... you would've lost the bet. I use a single screen, no widgets, no weather stuff, bluetooth off, wifi on (but currently turned off), and nothing extraneous. I run Android about as light & frothy as you can get! I prefer speed over just about everything.
Any other thoughts, though? Perhaps I should re-load Autostarts to see if there's anything strange launching at boot time...

Interesting. Any ideas what would be pinging the cell standby so much? I'm in a high-bandwidth area (full bars), so it's not like the phone is struggling to get signal. I use Gmail and Exchange, but my Exchange sync is set to "hourly", rather than push.
Doesn't seem like I'd need to disable my 3G connectivity. I certainly have never had to before.

You should probably reflash the update. JI6 was great on my phone, no hiccups, no lag, perfect GPS.
Also, you should recalibrate your battery after the update and give it a few days to settle down. I always get horrible battery life after flashing a rom, but after a few cycles I'm back up to 24h+.

Honestly, I wouldn't know unless I knew your full setup. What I will say is that I do have a lot of widgets and apps running that pull from the internet but yet my cell standby isn't as high as yours. I haven't reduced any of my sync intervals either. The 3G radio can really drain battery fast, faster than even the screen so that is a problem.
Also, in JI6, they increased the strength of the radio so it drains even more battery. I am running the JI6 modem however.
You should use something like WatchDog to see what is constantly running and using CPU. That could give you an indicator of problem apps.

Well, I'm disabling some startup items: Visual Voicemail, Telenav, and Daily Briefing -- none of which I use. Maybe that'll help. I don't know...
I was really trying to run "stock" this time around -- not so much fooling and tinkering with things, but it doesn't appear to be paying off for me. Frustrating.

Oh wow, yea definitely you need to disable all of those. That's the first thing I do. I actually uninstall Visual Voicemail, Telenav, Amazon MP3 etc. ALL of those things constantly run for some reason even without you opening them once.

You're not alone. My battery life is terrible as well after the update. I'm losing 4% an hour on standby.
That said, my phone is smooth and working great when I do use it.

Amen to that. Except that the GPS is still unreliable.

I'm having terrible battery life as well.

i'm 24 hours unplugged, sitting at 27%
all stock JI6

Again, if you didn't do so after the update, wipe battery stats and then do a few full drain/charge cycles. My battery life always sucks after flashing a new ROM, but it always goes back to normal given time.
Sent from my SGH-T959 using XDA App

after the update for me, my gps is much better, but i actually have more lag then i had stock before....
so I need to either flash a kernel, lag fix, or a rom with at least one of those.... its kind of frustrating to have lag just from opening or closing a simple app, messages, or call... I honestly cant believe a phone with these hardware specs can have lag just from somthing as simple going into the dialer and exiting out...

Battery life seems to have decreased a little but still getting a good 20+ hours. GPS is a little better with use wireless networks. Lag is an issue now though. Didn't have much before a the update. Hopefully its solved in another update or froyo.

So I applied the update on Tuesday through Mini Kies. First experience with this update, it's been great. My phone seems to faster, really I hardly experience any kind of lag or slowdown (and this is in comparison with my stock vibrant running OCLF). Battery life even seems to be better, but that is probably to do with conditioning. So everything has been good except for the fact that my phone has froze on me TWICE today. I'm thinking it's something to do with the apps though. I was in Layar and it was working for a bit when suddenly, it froze, I didn't have to pull the battery I just held the power button down for a good 5-10 seconds and it restarted. The other time was in a game, which kind of concerns me. I suppose I can reinstall both and see how that goes. I'm thinking it has more to do with the apps possibly being corrupted. The first thing I did was install the 2.2 market on my phone and I ran the update all function on like 15 apps that needed updating. Not a good idea imo, the market went crazy and forced closed a couple of times. I'm not entirely sure what is going but it seems like my phone is only freezing in certain apps. I hope it's not just some random freeze that can happen at anytime, that wouldn't be no good.

You guys complaining about battery life... i would Love to have your times. I got 3 hours and 8 minutes today on a fully charged battery.

I am using, B137 custom rom by Fibblesan from modaco.
http://android.modaco.com/content/h...rom-for-the-huawei-u8800-with-online-kitchen/
Reason.
Works flawlessly, can do normal calls,browsing the network, flash works perfectly and no shuttering lastly battery life is great, holds quite long. I would also point out that when questions are asked most help when they can @modaco.
I would say hearing opinion is a small reason to try a rom, biggest would be to experience the rom then see if its really good.

With 3g, wifi on and light web browsing I get around 11 hours of usage until next charge. If I do not play around for such long time it can hold for 3 days in sleep doing nothing. But if I do normal activity, which involves, music,web,3g,sms and some calls + games. I will have 20 % left from 08:00 to 23:00 and thats no problem 20% is fine enough for a night sleep, and charge in the morning !

so is like my galaxy ace, form 08:00 to 23:00, i use 70% of the battery, with the sincro on all the time, using my emal like sms, it means that i send a lot during all day, wifi turn on during 8 hours and some games and web.
i still dont have the x5 but iam waitting for it, but i thought that the battery could be longer

Why would it be longer?
First thing you need to understand, the concept of why smartphone battery sucks. They don't evolve as fast as the smartphones itself. No one seems to wish add more power into their small batteries for the smartphones, thus making it look stupid.

ok i understand and i know, but the software could improve the battery life in some way

Yeah, software can only make sure a certain amount won't go to waste, for example stopping useless workload.

I don't mean to upset anybody, but I think that battery consumption is 80% related to the hardware and the rest to software. I used to have Wifi, bluetooth, 2 e-mail accounts with push on non stop, on my old Iphone 3G and battery used to hold for at least 2 days. Now, because this battery is 3 years newer, wouldn't you think that there should be improvements? The fact that you get 3 days out of this phone's battery, makes me think that you're lucky...I never got more than 2 days, with all sorts of ROMs, including FLB.
The rule "what you pay is what you get" reflects the reality here, quality hardware makes the difference, simple as that. I like the U8800, but to be able to get more life out of the battery, the quality of hardware needs big improvements.
As an example, the bluetooth on the Iphone use to work in the proximity of my car, but with the U8800 it disconnects while I'm in the car... not to mention the wifi, that's flaky as...I'm not bagging the U8800, for $300 brand new, it's definitely worth buying, but if you want a bit more quality, pay the difference and get the Desire or something.

First: No one who needs 3+ day battery should buy a smartphone! If you want a super battery, go to a dumbphone with a xpto 8+ days battery. I my opinion, a smartphone with a 24h battery (wifi on, 3G on, network data on, good brightness, some gps, etc) is the perfect deal. I couldn't 100% test the battery duration of the Huawei because it's still network locked, so I've done any calls and any sms/mms, but with wifi on, auto-sync, FB sync, tweetdeck sync, google account sync, some internet browsing, lots of social network browsing and good brightness, there's now 25h uptime and 32% remaing. Is this bad? I don't think so...
Second: Go ahead, compare a 500€ iPhone to a 150€ Huawei
BTW: It's network locked but I'm using the original SIM and it's working properly. I've done any calls or sms but it's not in flight mode, it's completely operational... Except for the fact that I aint no friends using TMN ahah SO, the battery duration isn't much affected by this fact.

Iphone is more than 3 years old and worth less than $100...Not sure what you're talking about. Or do you still think that Iphone 3g is worth 500??
The topic here was to decide if to buy U8800 or not. If you think that a "smart-phone"s battery should last 24h, then you deserve this phone... I'm thinking, "no go". You can get a whole lot more from a Desire.
In my view, the specification says 370h in standby, with wifi on, you should still get 100h...not 24h.
BTW, can you give me an example of an $300 "dumb-phone" ? )

só tiago, I can see that you are Portuguese, I'm to. so with a lot of using you can get one day of battery, with an extreme use. because for me I will use a lot the email because I use it like sms to.my girl that is out of the country so it should e on all the times. the rest us a normal use with calls something like 2 hours of phone calls.

Sorry, I thought you have the 4G... I take back what I said about 500€ iPhone.
370h only if it's sleeping all the time without data, syncs, wifi, etc... With a full smartphone use, 100h are impossible to get otherwise I think the user is not using it with full capacities... Like I said, with all-day wi-fi, sync, notifications, data transfer, good brightness, some GPS, browsing, sms, calls, etc etc (full smartphone use), get 24h+ battery is very hard... My 2 cents.
$300 dumbphone? A "dumbphone" is a phone for those who don't need a smart one, so I don't see the point of your question... If anyone is thinking on spending $300 on a phone, I doubt a dumbphone will do the needs.
(Sorry for my bad English)

What I meant was that you can't really find dumbphones any more, in less they are $20 or something... Anyway, the whole idea is that I think the battery should hold longer than 24h, with wifi and minimal usage. With this phone, you can barely achieve that...
If the initiator of this thread wants more battery life, he should reconsider.

[Q] kernel for GB retail?

hi guys im a newbie about android. yesterday i have updated my phone with motorola update gingebread for ms2 retail (italian).
I wish to know if is there a kernel for improve battery duration, i`ve searched around and on this forum but have found nothing.
thx!
edit: around i`ve read that i can improve my battery life installing setcpu or milestone overclock and setting up some profiles with cpu and monitor differents frequences.
anyone tried it? is this helping battery life and are these app compatible with new stock gingerbread 2.3.4 for ms2 retail?

any advice guys? im still searching around, can someone address me to on the right way(aany guide or thread talking about this).

I have never had any battery issues and still don't. Still rockin' at about 23 hours non stop with WiFi and 3G on and brightness set to automatic.
I actually realized I didn't even undervolt yet, so I guess battery performance might be improved.

hi dude, thx for ur reply.
do u use a custom rom? or different battery?
as i told i use a ms2 unbranded with stock rom, now updated battery seems going better now than when i was on froyo but still low hard arriving in the night if i use wifi

The only kernels we can get on ms2 are the stock ones thanks to the locked boot loader. If you downlooad milestone2toolbox from one of the threads in the android development forum (pretty sure miui has it on first page), it has a pretty nice over/underclock feature. And custom roms will help you battery life somewhat, however if you are like me and can't put your phone down, and are on it all the time, you'll still only get like 4 - 6 hours battery life .
Once and once only, I squeezed out 24 hours, I was very proud. Granted that I was bored out of my brain, but still managed about 15 minutes of gaming, a couple calls and about a dozen sms, 1/2 hour browsing xda, another half on android market.
And I don't know about other people's experience with it, but Juice defender seemed to have actually DECREASED my battery life - quite significantly I might add. A friend at work tried it too and unistalled that same day from the amount of drain he got :/. I suspect perhaps its more useful on eclair, but with gingerbread (and maybe froyo) it is redundant.
Moral of the story - underclocking is your friend for battery life. I'm underclocked to 800 mhz and barely notice any performance loss - even when playing NOVA hd
Sent from my A953 using xda premium

hey dude thx for ur reply!
ok ill try tool box. yeah i think same on juice defender.
well i`ve not calibrated my battery and dont know if it helps, but my battery life especially when use wifi is very low!btw ive noticed that the over 60% of consume of the battery juice is about screen. I was thinking of underclock gpu too when i dont use games etc... is that possible on milestone 2? i`ve found nothing around about that

I didn't know phones could have gpu clocked? Unless you were just speculating
Yeah the screen is a bit of a power hog, but just remember that it has back lights lighting it the whole time your using it, so that's the reason it drains so much. So either setting screen brightness to low or automatic is a plus. Obviously low is best but its pretty hard to see . Autosync/gps will push apps like facebook into the lead too.
I'd recomend one of those recharable portable batteries that has a usb out port, they are so handy in a pinch it's a bit of a decent investment too since you can just plug whatever usb cable you have to charge any device really
Oh and using your phone's internet is a crazy, crazy drain to the battery!

Poor Battery Management!!!

I am using this phone from Last 1 week and one thing I've noticed that battery management is very poor. it keeps decreasing without no usage even when the phone sitting on the table. the phone has 4000Mah of battery but there is battery usage tab in the settings like stock android to track down what is consuming more battery. The battery is not even lasting a full day.
I think its better if someone makes or port a Stock Android-based ROM for Samsung A51 or get the solution for Poor battery management.

I think its better if someone makes or port a Stock Android-based ROM for Samsung A51 or get the solution for Poor battery management.

I think you can check battery management in Setting > Device Care > Battery.
I agree with you that the battery is poor. I cant use the phone in 1 day without charging.

Thanks for the update, let me track down the background apps for 24 hours, let see if I can help to minimize the battery drainage. BCS its the first time when I am using a Samsung phone. I usually like to use phones with stock android & never faced this issue before regarding the battery

Human consumption. My battery lasts 3 days

Well, not sure if you just purchased the phone to keep looking at it and only making and receiving calls?️

Hello !
You said that u can use u're phone 3 days and that's because of the firmware.. Can you give me more information about that please ?
I got recently this phone but the 4000mah is drained too fast, I optimize a lot of thing and got the minimal app in background or fonction like sync. The proof is that One UI is the app that drain the most of my battery.
Finally i think that is because of the screen..
But do you have an solution with a firmware or root for the autonomy of this phone ?
Sorry for my english and thanks for you're answer !
